A.J.S. (119.)
7 h.p.; 74x93 mm. (800 c.c.); V twin four-stroke; side-by-side valves; drip feed lubrication; Amac carburetter; chain-driven magneto; three-speed A.J.S. countershaft gear; all-chain drive; Dunlop 700x80 mm. tyres. Price: With sidecar £215; solo £159 10s.
A. J. Stevens and Co. (1914), Ltd., Graiseley House, Wolverhampton.
Long famous as a machine embodying every luxury that care in design can provide, the new A.J.S. will even improve its reputation. For 1921 a larger engine is fitted with roller bearing big-ends, a three-ring piston, and larger cooling fins. Also, an internal expanding front brake has been adopted, which is operated by pedal, thus doing away with the inverted handlebar brake levers. Primary chain adjustment has been elaborated, the gear box being moved backwards forwards by a screw, which provides easy and accurate positioning...

Blackburne. (12.)
Burney and Blackburne, Ltd., 28, Conduit Street, London, W.l.
A substantially constructed dual-purpose machine is the 4 h.p. Blackburne. It is fitted with 28in. wheels and all-chain drive, protected by a guard over the upper length of the chain. A contracting band foot brake operates on the rear wheel, and the pedal. is conveniently situated on the off side. Brampton spring forks are a standard fitting, and the Blackburne engine is, of course, employed. As is well known, this popular power unit has an outside flywheel and a detachable cylinder head held in place by three long studs and nuts. The low riding position, large footboards, and wide handle-bars combine to give the rider a feeling of security, and the black finish is admirably set off by the red panelled tank...

BAT. (69.)
6 h.p.; 76x85 mm. (770 c.c); twin-cylinder four-stroke; side valves; hand pump lubrication; Amac carburetter; chain-driven Magdyno; three-speed Sturmey-Archer gear; all-chain drive; 28x3in. tyres.
The Bat Motor Manufacturing Co. (1918), Ltd., Penge, S.E.
One of the pioneer firms of the motor cycle industry, the Bat has always had a high reputation, particularly for speed and workmanship. The 6 and 8 h.p. machines shown on the stand do not differ greatly from their predecessors, but all of them are good examples of the modern motor cycle, and in particular of the method whereby the parts are arranged, so that even the smallest details are accessible. The ordinary model has a twin V engine driving the rear wheel through a countershaft gear box and clutch, transmission being entirely by chain. Both chains are covered in by metal casings of substantial and stiff design...

Connaught. (Stand 95.)
The Bordesley Engineering Co., Ltd., Birmingham.
Quite the most attractive exhibit of the Connaught stand is the fascinating little sidecar outfit, for the performance of which we can vouch after an extended road test. Our readers will remember that the Connaught, which was a pioneer among two-strokes, has always embodied a combined inlet and exhaust manifold so that the incoming charge is well warmed. The engine is well constructed with ample bearing surfaces and drives by chain to a two-speed countershaft gear with handle-bar controlled clutch and kick-starter. This primary chain is protected by a neat cast aluminium cover. Final drive is by belt...

B.S.A. (Stand 69.)
4½ h.p.; 85x98 mm. (557 c.c); single-cylinder four-stroke; side-by-side valves; drip feed lubrication; B.S.A. carburetter; M-L chain-driven magneto; three- speed constant mesh gear; chain drive; 26 x 2½ in. tyres.
B.S.A. Cycles, Ltd., Small Heath, Birmingham.
For single-cylinder side-car work B.S.A. machines have made a reputation for reliability under hard usage. At the last Olympia Show, the company introduced a twin-cylinder model which has firmly established itself during the present year, and the same success is bound to follow the new single-cylinder machine which takes the place of the 4½ h.p. model previously marketed. This new machine may be said to be a redesigned proposition, using the older model as its nucleus, so externally those familiar with the well-known single will not, at first sight, observe much difference between the old and the new models. There are differences, however, and all are to the good. First, perhaps, should be mentioned the redesigned timing gear which now embodies external cams which materially reduce mechanical noises. There are also several other points which have been improved with a view to obtaining a great degree of silence, a new and larger silencer being one of them...

Ariel. (Stand 97.)
4½ h.p.; 86.4x100 mm. (585 c.c.); single-cylinder four-stroke; side-by- side valves; mechanical lubrication; B. and B. carburetter; chain-driven magneto; three-speed sliding pinion gear; chain drive; 28x3in. tyres.
6-7 h.p.; 73x95 mm. (795 c.c); twin-cylinder four-stroke; side-by-side valves; drip feed lubrication; B. and B. carburetter; chain-driven magneto; three-speed sliding pinion gear; chain drive; 28x3in. tyres.
Ariel Works, Ltd., Bournbrook, Birmingham.
Two new models are this year exhibited by this well-known Birmingham firm, and, except for the engines, the machines are identical. The 6-7 h.p. twin engine in one of these is little altered since the last Show, and is one of the few long-stroke twins on the market. The gear boxes, too, are as in the 1920 models, and are good examples of three-speed counter-shaft gears, in every way conforming to up-to-date practice. The 4½ h.p. single-cylinder engine is entirely new, embodying mechanical lubrication and a decompressor t facilitate starting. For this reason an exhaust valve lifter has been dispensed with. A plain bearing of exceptionally large diameter is used on the driving side main shaft, oil being led to it by ducts cast in the crank case.
A massive steering head, particularly large forks...

Alecto. (Stand 147.)
3 h.p.: 76x76 mm. (345 c.c); single cylinder two-stroke; drip-feed lubrication; Amac carburetter; cam-driven magneto; two-speed Burman gear; chain and belt drive; Dunlop 26x2¼ in. tyres. Price £87 10s.
Cashmore Bros., Grove Road, Balham, London, S.W.12.
Inspired no doubt by the fine performance of their small two-stroke engine at Brooklands, where it captured twenty-one long-distance records in August last, Messrs. Cashmore Bros, have gone very thoroughly into the question of lightweight sidecar work. The result of their investigation forms the chief exhibit on this stand - the specially designed 345 c.c passenger outfit. This machine has a considerably stronger frame, a larger tank, wider footboards, bigger spring forks and a different type of mudguarding from the solo model, and sells at £125. Another addition to their range is a single-geared T.T. machine...

Saltley. (Stand 175.)
4 h.p. Blackburne; 85x88 mm. (499 c.c.); single-cylinder four-stroke; side-by-side valves; B. and L. drip lubrication; Amac carburetter; chain-driven magneto; three-speed Sturmey-Archer gear; chain and belt drive; 26 x 2½ in. tyres. Price £130.
Saltley Cycle Co., 86, Snow Hill, Birmingham.
The Saltley Cycle Co. stage three neatly designed machines, embodying the 4 h.p. Blackburne, the 2¾ h.p. Vulcanus, and the 2½ h.p. Villiers power units. All three machines are excellent examples of the assembled type, and neatly finished in handsome colouring...

Chater-Lea. (Stand 90.)
2½ h.p.; 70x70 mm. (269 c.c.); single-cylinder two-stroke; drip feed lubrication; Amac carburetter; T.B. chain-driven magneto; two-speed countershaft gear; chain and belt drive; 26 x 3 in. tyres. Price £70.
Chater-Lea, Ltd., 74, Banner Street, London, E.C.1.
A pleasing looking little lightweight of standard design is the 2½ h.p. Chater-Lea, black and gold finish being employed. Mudguarding has been particularly well carried out, and the sloping top tube provides a low riding position and neat appearance. A lever control for the magneto is fitted to the tank, which also carries a Best and Lloyd drip feed lubricator. Special Chater-Lea spring forks are, of course, fitted, and a single toolbag is carried on the near side of the carrier. The countershaft gear box is particularly well carried out, and is controlled by a lever and quadrant on the left side of the tank.
8 h.p.; 85x85 mm. (964 c.c.); two-cylinder four-stroke; side-by-side valves; drip feed lubrication; Amac carburetter; T.B. chain-driven magneto; three-speed sliding gear; chain drive; 700x80 mm. tyres.
A luxurious sidecar machine is seen in the 8 h.p. Chater Lea twin...

Hobart. (Stand 102.)
Hobart Cycle Co., Ltd., Coventry.
This machine is the simplest, and most inexpensive of the wide range of Hobarts - all lightweights. Petroil lubrication has been adopted only this year, and only for this particular model. Owing to the design of the bottom bracket, which is specially slotted for this purpose, a Chater-Lea two-speed gear box may be fitted without any structural alterations. Should, therefore, the purchaser of a single gear Hobart desire later to go in for serious touring or mountaineering in a small way, he will be able, given the necessary sprocket, etc., to effect a conversion himself...

WILKIN. (Stand 146.)
4 h.p. Blackburne; 85x88 mm. (499c.c.); single-cylinder four-stroke; side-by-side valves; drip feed lubrication; Amac, B. and B., or Senspray carburetter; chain-driven Magdyno; two-speed Sturmey-Archer gear; all-chain drive; Wood-Milne or Hutchinson 26in. x 3in. tyres. Price £190 with sidecar.
Wilkin Motors, Ltd., Onslow Road, Sheffield.
The officially observed "Round the Coast" test is still fresh in the minds of the public; and just as surely have the lessons of that test been utilised by Wilkin Motors. Mudguarding has been much improved and strengthened, and the chain cases are designed to be completely mud and waterproof; albeit they detach with little trouble. Specially thoughtful is the provision of a means of clipping the chains in position, and thus avoiding much irritating "fishing" in the lower half of the gear case...

F.N. (139.)
7 h.p.; 52x88 mm. (748 c.c); four-cylinder four-stroke; valves on either side; mechanical lubrication; Amac carburetter; gear-driven magneto; three-speed gear; shaft and bevel drive; Palmer Cord 26in.x3in. tyres.
F.N. (England), Ltd., Kimberley Road, Willesden Lane, London, N.W.8.
Belgium has always been noted for its engineering products, particularly for the excellence of its foundry work, and it is rather disappointing that only one Belgian motor cycle manufacturer is seriously represented in this country. However, the good points of that one make - the F.N. - probably compensate for lack of variety. From very early days the F.N. four-cylinder has been steadily carving a niche for itself in the heart of the British public...

ZENITH. (87.)
3½ h.p. Bradshaw; 68x68 mm. (499 c.c); horizontal twin-cylinder four-stroke; overhead valves; mechanical lubrication; B. and B. carburetter; gear-driven magneto; Zenith-Gradua gear; belt drive; Avon 26x2-¼ in. tyres. Price (provisional) £130.
Zenith Motors, Ltd., Hampton Court.
Probably the greatest attraction on the Zenith stand is the new Bradshaw engine sporting machine. The engine of this may be regarded as the first attempt at really scientific oil-cooling. As has already been described in The Motor Cycle, the cylinders are sunk inside the crank case, only the heads being exposed. The forced-feed lubrication pump provides a constant stream of oil from a separate tank in which it is kept cool, and the cylinders and pistons...

SUNBEAM. (Stand129.)
3½ h.p.; 85x88 mm. (499 c.c.); single-cylinder four-stroke; side-by-side valves; drip feed lubrication; Amac or B. and B. carburetter; chain-driven magneto; three-speed constant mesh type gear; enclosed chain drive; Dunlop or Bates ,650 x 65 mm. tyres. Price £155 8s.
John Marston, Ltd., Sunbeamland, Wolverhampton.
Although the capacity of the Sunbeam single-cylinder engine is only 499 c.c, it has proved capable of the severest sidecar work, and for dual purposes it stands in the highest rank. Famous long ago on Sunbeam pedal cycles, the oil bath gear case...

Francis-Barnett. (Stand 34.)
2¾ h.p.; 70x76 mm. (292 c.c); single-cylinder four-stroke; side-by-side valves; splash lubrication; B. and B. carburetter, chain-driven magneto; two-speed Sturmey-Archer gear; chain and belt drive; 26 x 2¼ in. tyres. Price £89 5s.
Francis and Barnett. Ltd., Lower Ford Street, Coventry.
The Francis-Barnett lightweights are among the prettiest in the Show, and one interesting result of the 1921 taxation scheme is that the makers are careful to state the exact weight of all their models. With empty tanks and without lamps or tools, the weights range from 152 lb. for the single-speed two-stroke, to 195 lb. for the de luxe model...

RUDGE. (Stand 113)
3½ h.p.; 85x88 mm. (499 c.c); single-cylinder four-stroke; inlet over exhaust valves; pump lubrication; Senspray carburetter; gear-driven magneto; variable speed gear; belt drive: 650x65 mm. tyres. Price £110 5s.
Rudge-Whitworth, Ltd., Coventry.
It is interesting that the makers of the Rudge, as one of the few remaining exponents of the all-belt drive, have fitted an all-metal chain-belt to some of their latest Multi models. This belt is in effect a wide chain, to the links of which are attached sprung V shaped gun-metal plates...

Verus. (Stand 161.)
4 h.p. Blackburne; 85x88 mm. (499 c.c); single-cylinder four-stroke; side-by-side valves; drip feed lubrication; Cox-Atmos or Senspray carburetter; chain-driven Maglita ,; three-speed Sturmey-Archer gear; chain and belt drive; Dunlop 26x3in. tyres. Price with side-car £200.
Alfred Wiseman, Ltd., Glover Street, Birmingham. Very rapid has been the rise of the Verus. A trust in the value and lessons of reliability trials probably accounts for this in no small degree. Anyhow, whatever the cause, the Verus now ranks among the aristocracy of the pastime, and careful examination proves that the position has been well earned...

Matchless. (Stand 68.)
8 h.p. M.A.G.; 82x94 mm. (995 c.c.); twin-cylinder four-stroke; overhead inlet valves; drip feed lubrication; B. and B. carburetter; chain-driven Magdyno; three-speed sliding gear; chain drive; spring frames 28x3in. tyres. Price with sidecar £231 12s. 6d.
H. Collier and Sons, Ltd., 44, Plumstead Road, Plumstead, S.E. With a reputation second to none, the Matchless Model H is unrivalled for sidecar work, and with its spring frame and very complete equipment it must be numbered amongst the luxurious sidecar machines. Detachable and interchangeable wheels are provided, and it may be obtained with either the M.A.G. or J. A. P. engine...

F. E. Baker, Ltd., King's Norton.
Great interest was aroused at last year's Show in the first models of this machine, and the latest type shown this year is no less noteworthy. In internal design of the engine itself, certain alterations have been made, especially in the shape of the exhaust port and the piston deflection...

Whippet Miniature Motor Cycle. (Stand 26a.)
l½ h.p.: 56x61 mm. (150 c.c); single-cylinder four-stroke; overhead valves; drip feed lubrication; Vici single-lever carburetter; C.A.V. chain-driven magneto; single-speed gear; chain drive; Wood-Milne 18x2in. tyres. Price £58 10s.
W. G. Hayward and Co., Ltd., Twickenham.
Three distinct models are shown on this stand, which differ only in minor details. In every case the motive power is the same; the interesting little Whippet engine is fitted with an aluminium cylinder and a steel liner. The cylinder head is of cast iron...

Edmund. (Stand 145.)
2¾ h.p. Blackburne; 71x88 mm. (349 c.c); single-cylinder four-stroke; side-by-side valves; drip feed lubrication; Amac carburetter; E.I.C. chain-driven magneto; two-speed Burman gear; chain and belt drive; Dunlop 26x2 ¼ in. tyres. Price £105.
C. Edmund and Co. (1920), Ltd., Crane Bank, Chester.
Both front and rear springing on the Edmund is now very advanced for a lightweight machine. The rear system of springing is no new untried device; but, for the benefit, of those who are newcomers to the pastime, we will recapitulate. Briefly, the top tube, to which is attached the petrol tank, is pivoted at its forward end...

Dunelt. (Stand 138.)
4½ h.p.;, 85x88 mm. (499 c.c); single-cylinder two-stroke; drip feed lubrication; Cox Atmos carburetter; M-L chain-driven magneto; three-speed Sturmey-Archer gear; chain and belt drive; Hutchinson 26in. x2½ in. tyres. Price £115, with sidecar and spare wheel £150.
Dunford and Elliot (Sheffield). Ltd., 95, Bath Street, Birmingham.
It is satisfying to note that the Dunelt is making good, striking out as it does on new and hitherto untried lines, and yet with a definite reason for its divorce from Dame Convention. To combine power for sidecar-work with a low initial cost is the raison d'être of this machine, and we think that the makers have achieved their aim...

CALTHORPE. (Stand 112.)
3 h.p.; 75x79 mm. (350 c.c); single-cylinder two-stroke; drip feed lubrication; B. and B. carburetter; Sturmey-Archer gear; chain-driven magneto; chain and belt drive; Dunlop 26x2-in. tyres. Price £115 10s., with sidecar and lighting set.
Calthorpe Motor Cycle Co., 16, Barn Street, Birmingham.
One of the most interesting of the new lightweight sidecar machines is the 3 h.p. two-stroke Calthorpe. This model, which is fitted with the Calthorpe 350 c.c engine, is noteworthy as being a very complete outfit at an extremely moderate price. It is capable of averaging well over 20 m.p.h. on give-and-take roads with a passenger, and will reach a maximum of nearly double this figure. It is to be observed that in an effort to prevent the ruthless overloading...

Allon. (Stand 62.)
2 ½ h.p.; 70x76 mm. (292 c.c); single-cylinder two-stroke; drip-feed lubrication-; Senspray carburetter; Fellows chain-driven magneto; three-speed Allon gear; chain and belt drive; 26in. x 2¼ in. tyres.
Alldays and Onions, Ltd., Matchless Works, Birmingham.
The Allon is here shown for the first time with a three-speed gear box of the firm's own manufacture, the change making the machine more suitable for sidecar work. Accordingly a complete outfit is exhibited and is a small but practical vehicle not too elaborate, yet with all the fittings that the average rider would desire. The engine is quite a normal type two-stroke also made by the firm, and transmission, is by chain and belt. Two models are offered, the engine in each case having the cylinder cast integral with the top of the crank case...

Royal Ruby. (Stand 125.)
8 h.p.; 85.5x85 mm. (976 c.c); twin-cylinder four-stroke; side-by-side valves; drip-feed lubrication; Amac or B. and B. carburetter; chain-driven magneto; three-speed Sturmey-Archer gear; all-chain drive; Dunlop 28x3in. tyres. Price £235.
Ruby Cycle Co., Ltd., Royal Ruby Works, Altrincham.
Notable for its excellent system of springing, employing laminated leaves for both front and rear wheels, both the 3 h.p. and 5 h.p. Royal Ruby are again attracting the attention of prospective buyers. A very fine sidecar outfit is the leading feature of the stand, and employs an 8 h.p. J.A.P. engine. Notable points in the construction of the machine are the locking plates on the spring fork shackles. These enable the shackle bolts to have dome-ended nuts on them, thus preventing the ends of the bolts from getting rusty. A strengthened front down tube, which consists of a main central tube with a single tube of smaller section on each side of it, is another distinctive feature, while another good point is the well-designed spring housing below the saddle, and the double down tubes from it; one goes to the rear engine plate and the other to the front end of the chain stays, immediately behind the gear box...

Quadrant. (Stand 41.)
6 h.p.; 87x110 mm. (653 c.c.); single-cylinder four-stroke; side-by-side valves; hand pump lubrication; Amac or Senspray carburetter; gear-driven magneto; three-speed Sturmey-Archer gear; chain drive: 26x2½ in. tyres. Price with side-car £155.
March Newark and Co., Ltd., Lawley Street, Birmingham.
The Quadrant is a serviceable and steady mount, suitable for everyday hard work without needing undue care or attention. The principal model is the new 6 h.p., chiefly notable for a very wide and substantial crank case, which is kept smooth on the exterior, and, therefore, is exceptionally easy to clean. This idea has been consistently carried out, in that the number of plated parts on the motor cycle is reduced to a minimum. The riding position, and shape and length of handle-bar are good, and the sidecar chassis appears to be quite substantial enough to stand the exceptionally rough usage which this type of machine is usually accorded...

Victoria Works, Dennistoun, Glasgow.
Stands Scotland where she did? (sic) However, the absence of quantity is more than balanced by the quality and remarkable value of the only exhibit from across the Border. Most striking is the value of the sidecar outfit offered, as specified above, at the figure of £125 inclusive.

The Cotton Motor Co. Bristol Road, Gloucester.
Triangulated frame construction has been for years the text of the theorist, but in practice pedal cycle ideas and fashions remain very much with us. Eminently satisfactory as the conventional frame proves, it should not be regarded for this reason as le dernier cr; and an advanced design, such as the Cotton, which breaks away entirely from convention, deserves every encouragement, for in that direction progress lies...

Bayliss, Thomas and Co., Ltd., King's Road, Tyseley, Birmingham.
An extensive range of lightweight machines provided by this firm, as in addition to the Blackburne-engined model, with two-speed gear, clutch, and kick-starter, a similar model may be obtained with a 2½ h.p. Villiers two-stroke engine. This, again may be equipped with a plain two-speed gear box, or it may be single-geared, thus providing a range of four models on the same general lines. With footboards, curved mud shields and ample mudguards, the Excelsior should be a lightweight suitable for any weather....

Levis. (Stand 121.)
2½ h.p.; 62x70 mm. (211 c.c.); single-cylinder two-stroke; drip feed lubrication; Amac (or other) carburetter; chain-driven magneto; single-speed gear; belt drive; Hutchinson 24x2¼ in. tyres. Price £60.
Butterfields, Ltd., Stechford, Birmingham.
Two-strokes as a rule are suspected of being uneconomical that is to say, their consumption is considered to be high in proportion to their power. Therefore, great interest is being shown in the result of the recent Levis consumption test, when the machine averaged over 20 m.p.h. over a fifty-mile course, with a petrol consumption at the rate of 320 m.p.g.

Campion Cycle Co., Ltd., Robin Hood Street, Nottingham; and Nottingham Motor Cycle Taxi Co., Byard Lane, Nottingham.
Although these two firms (in conjunction) intend their vehicle primarily to be a sidecar-taxi outfit, there is no doubt that the luxurious two-seater here staged will appeal in addition to the family man. Another standard Campion outfit of last year's specification is shown; but, as this type is being discontinued, we will confine our description to the two-seater...

Dalton Motor Co., Ltd., 17-19, John Dalton Street, Manchester.
The 4 h.p. model is an attractive double-purpose mount, suitable for solo riding, and yet sufficiently powerful for a sidecar in all ordinary districts. One of the chief features of this mount is the careful manner in which the mudguarding has been studied. The rear guard extends well over the back wheel, and is provided not only with deep valances, but a special guard over the belt. Footboards sloping to a comfortable angle are provided. As regards the frame, combined lugs are employed where possible, and the tool-bag cases are welded on...

Raleigh Cycle Co., Ltd., Nottingham.
Although it was exhibited at last year's Show, the flat twin Raleigh has only lately been put into production. In fact, the Show exhibits are the first production samples, so that the machine has not yet been seen much on the road, and is probably not familiar to readers. Perhaps the most noticeable point about it is its neatness, when one considers that the engine is a flat twin of 700 c.c...

Among the interesting points of the Reading Standard is the fact that it has the largest engine of any motor cycle in the Show
The new cylinder head of the Reading Standard. The valve springs are enclosed m cases with a locking ring beneath.
READING STANDARD. (Stand 37.)
10 h.p.; 85.8x95.4 mm. (1,170 c.c.); twin-cylinder four-stroke; side-by-side valves; mechanical lubrication; Schebler carburetter; Splitdorf gear-driven magneto; three-speed countershaft gear; chain drive; Firestone 28x3in. tyres.
Stanley. J. Watson, 37, Sheen Road, Richmond, Surrey.
The Reading Standard was one of the first American-made motor cycles that conformed in design to British ideas as to valve disposition. It is, however, rather more up-to-date than many British machines in that mechanical lubrication is fitted. Like all American big twins it is strongly constructed, made to withstand roughly roads, and is provided with a comfortable saddle. The current for the electric lighting is supplied from a Splitdorf generator.
Following American practice the clutch can be actuated either by the foot or by hand, and unless the clutch is withdrawn the gear lever cannot be moved owing to the interlocking device provided. The models shown are all fitted with sidecars with the exception of one.
Although the engine is rather larger than is fitted to British motor cycles the complete machine is compactly arranged, and is not clumsy in appearance.
Priory. (Stand 6.)

Douglas Motors, Ltd., Kingswood, Bristol.
The new Douglas sporting engine has already been described in our columns. Only in its main lines does it follow existing Douglas practice. The valve gear is quite new. Both cylinder heads are detachable, and above the valve rocker bearings (which form part of the casting), there is a small ribbed aluminium chamber, which is filled with oil about every thousand miles, and lubricates the valve rockers by a wick feed. Engine lubrication is also new; a worm-driven pump on the top of the crank case draws oil from the tank and forces it through a sight feed to two pipes which lead into the base of each cylinder...

This exhibit comprises single gear and multi-speed lightweights fitted with the Orbit engine. The most interesting item of the specification is the swinging bracket on which the gear box is mounted in the multi-speed models. The bracket swings on a pivot pin; its arc of travel is adjusted by two set screws locked by four nuts, so that the chain tension can be set to very fine limits without any possibility of disturbing the alignment. Any make of gear box can be fitted to this bracket, and the requisite variations of chain or belt line are easily made with the aid of an adapter boss for the flywheel...
