Gradior.
A new machine for the 1912 market is the Gradior, the production of the Gradior Machine Co, Stafford. This machine derives its power from a 3½ h.p. J. A. P. engine, and has a plate clutch on the engine-shaft operated from the handle-bar by Bowden wire...

3½ h.p. Sidecar New Hudson.
The New Hudson Company have decided to market a 3½ h.p. bicycle specially suitable for sidecar work.
At first sight the new model does not appear to differ greatly from this year's 3½ h.p. type, but on examination one sees that the machine has been greatly strengthened in many parts...

A New Arno.
The Arno Co. will market a new T.T. model for 1912. They will retain their already well-known power unit, in which the engine, magneto, carburetter, and footrests can be detached by removing three bolts and uncoupling the petrol union. The chief alterations will be in the frame. The head lugs are cast in one piece, and . the rear lug is of novel and neat appearance, as will be seen from the illustrations. This also is cast in one piece, and is designed to give great strength at the joints and a low saddle position...

Rover.
The Rover motor bicycle for 1912 will be very little changed in outward appearance from the current year's model. Minor improvements are being made, but these alterations apply to the detail work only. The wheelbase will however be shortened, and a consequent reduction in the weight will result. A sidecar combination is also on the tapis for next year.

The Bosch Magneto for 1912.
If there is one part of a motor cycle which goes wrong less than any other it is certainly the magneto, and hence it is a somewhat difficult thing to see how, having arrived at its present high stage of reliability and efficiency, it can be improved. In spite of this, the 1912 type of Bosch magneto is certainly an advance, both in design and construction, on any machine that has yet appeared, and we have no doubt that motor cyclists will appreciate the practical and well-thought out improvements it contains...

The Pilot Spring Fork.
The Pilot spring fork, made by the Pilot Cycle and Motor Co., Soho Road and Farm St., Birmingham, which we illustrate herewith, is of very neat appearance. The forks slide through round tubes on either side of the head, and while the fork is able to give to road shocks the friction of the tubes prevents bouncing and oscillation. Another point is that in the unlikely event of a spring breaking...

Two-speed Singer Lightweight.
The two-speed 3½ h.p. bicycle which we recently described will be one of the leading Singer machines in 1912. The company has now decided to apply its counter-shaft gear to the 2½ h.p. light weight model which has recently had such a remarkable run of successes. This smart little machine will also be supplied with the Armstrong three-speed gear, or if desired in its original form with a single gear.

Quadrant
The Quadrant Co. will list four models for 1912 - a clutch, three-speed, racing, and lady's model. In the first two cases, except, of course, for the rear hub, the machines will be identical, and will have a modification of this year's engine. The radiating fins have been removed from the inlet port and an improved adjustable pulley has been fitted.
The new racing type is fitted with an engine of 87 bore x 80 stroke, and the lady's machine, which we hope to illustrate shortly, will have an engine of 70x76 mm.

The Norton in 1912.
We recently had the pleasure of a chat with Mr. Norton on the subject of his 1912 models. He told us that he would make no great changes in his present types, but that owing to prolonged experiments with air cooling there will be a considerable increase of efficiency in the 1912 machines. He also told us that he would list a novel type of miniature machine. The engine, which is rated at 2½ h.p., is of the long stroke type with mechanically operated valves, placed one above the other. The cylinder is inclined with the ribs arranged so as to be parallel with the ground. The weight of the complete power unit, comprising engine, magneto carburetter, exhaust pipe, and engine clips, is stated to be only 28½ lbs.

A New F.N. Clutch.
The F.N. Motor Agency have just placed on the market a well designed and well made plate clutch, which may be easily fitted to all ancient and modern four-cylinder F.N. motor bicycles. The illustration accompanying this notice shows the clutch in pieces, and it will be seen that in design it follows standard practice. The whole device takes the place of the usual flywheel...

Sidecar Combinations.
Passenger enthusiasts are to be well catered for next year. Among the new firms who have variably-geared motor cycle and sidecar combinations in course of manufacture for 1912 are : Rover, Enfield, James, Premier, Douglas, and New Hudson. In these machines the lugs for the sidecar fittings will be, in most cases, brazed to the frame.
A Two-speed James.
The 1912 James motor cycles will retain the same sized engines, that is to say, 86 bore by 96 stroke, but the combustion chamber and valve ports have been re-designed, and the diameter of the exhaust pipe increased, with beneficial results The magneto also has been slightly raised to give greater belt clearance. The frame will remain the same, but with the addition of a front wheel stand, a neat spring fork on Druid lines with scimitar blade side members, and a carrier specially designed to allow of the saddle being in the lowest possible position, and to carry special pannier tool-bags...

The 2¼ h.p. S.I.A.M.T.
THIS interesting little machine, which has recently signally distinguished itself in Italy, the country of its origin, is being handled in England by Mr. Scales, 336, Gray's Inn Road, W.C.
In describing any vehicle propelled by petrol vapour it is customary to begin with the engine. In the case of the S.I.A.M.T. we make no exception, and feel we can safely state that this is the most interesting part of the machine. The cylinder head is of quite an unconventional design, being screwed into the cylinder. It is guaranteed compression tight, carries both valves, which are of the overhead type...

Humber.
The Humber Company have produced an entirely new 3½ h.p. model for 1912 embodying many improvements and refinements. Following the practice of the lightweights, which have met with such success this year, the new 3½ h.p. has a désaxé crankshaft. The bore and stroke are 84x90 mm. The side by side valves are operated by adjustable tappets, having fibre insertions in the heads. This should go far towards deadening the valve chatter...

B.S.A.
The first of the 1912 B.S.A. motor cycles was seen on the road recently. It has a dropped frame. We have had a short run on one of these machines, and found the 1912 design of clutch beautifully smooth in action.

Comet-Precision.
Mr. Haydon tells us that it is his intention to market two new models – a 2½ h.p. lightweights with a free engine, and a 4¼ h.p. Colonial model with 5½in. ground clearance.
Calthorpe.
There will be four Calthorpe models for 1912. A 4¼ h.p. type for sidecar work, a 3½ h.p., a T.T.. and a 2½ h.p. All of these models can be fitted either with a new type of clutch on the expanding shoe principle, or with a new chain and belt counter-shaft two-speed gear, in which the gears are operated by taper friction clutches.
A 5 h.p. Twin A.J.S.
A chat with Mr. Stevens elicited the information that next year he will market a new 5 h.p. on the lines of his well-known 2½ h.p. engine, for sidecar work. The 2½ h.p. machine will not be greatly changed. The engine will be modified, but the greatest change is in the fixing of the gear box.
Condor.
The Condor Engine Co. are building a 4½ h.p. single-cylinder engine of 86 x 112 mm., which comprises two unusual features – (1) the oil is fed through the cylinder wall into the hollow gudgeon pin, and thence to the hollow big end and (2) offset cam gear...

Components, Ltd.
For next year, Components, Ltd., will enlarge their engine to 86½ bore x 85 mm. stroke, as used in the T.T. Race. Other features will be an automatic sight-feed lubricator, and an improved form of their variable gear. The control of the decompressor has been redesigned.
Another Counter-shaft Gear.
Bowden Wire, Ltd., is the latest firm to devote attention to the two-speed question. A fortnight ago we encountered Mr. Alec Ross on a Bat machine, fitted with the Bowden two-speed bottom bracket gear, which he was testing. It will shortly be dealt with in these columns.
The M.M.
We illustrate below the new 7-9 h.p. twin M.M., the bore and stroke of which are 82 x 91.5 mm. The magneto is a Bosch and the carburetter a Schebler. The attachment of the engine to the frame by the cylinder heads is interesting. The 4 h.p. single-cylinder model is of the same dimensions. It is illustrated on page 1082..

B.S.A.
We publish a section of the free engine clutch which has been fitted to this year's B.S.A. machines, the same design having been decided upon for 1912. As will be seen, it consists of a double cone keyed to the belt rim, which is gripped between blocks with corresponding grooves on each side, and sliding in the hub shell. We have had an experience with one of the B.S.A. clutch machines, and found the clutch beautifully smooth in action.
The Racing B. and B.
Last week we described the new design B. and B. carburetter for 1912, illustrating its special features on page 1037. Our description applies to the light-weight and heavyweight standard models, but the firm have a racing pattern for those who wish to obtain racing results. This carburetter is similar to the universal type, but has a straight through air opening with an extension pipe at the rear...

New 3½ h.p. Premier.
Am important improvement has been made in the 3½ h.p. model Premier for 1912. which still remains 85 x 88 mm. The whole cylinder has been redesigned, and outwardly has a neat pear-shaped appearance. while the cylinder head and valve ports have been somewhat modified in design. especially inwardly.
The frame has been considerably lowered, but the straight top tube is still retained. Detail improvements consist of a detachable rear mudguard, a belt rim guard, and an improved carrier with provision for pannier tool bag.
A New Quadrant Engine.
The Quadrant Co. have decided to add to their previous list of models an engine of 87x95 mm. for sidecar work. They will also manufacture a two-speed gear and free engine of their own. The gear will be placed in the rear hub, and will be of the epicyclic type.

Kynoch Redivivus.
Kynochs, Ltd. will place a 3½ h.p. motor cycle on the market for 1912. It will be fitted with the J. A. P. 85.5x85 mm. engine, Druid forks, and the B.S.A. two-speed gear or free engine at option.
A Small Twin J. A. P.
We visited the works at Northumberland Park one day this week where the J.A.P. engines are made, and fortunately found Mr. J. A. Prestwich at home. A discussion on 1912 prospects elicited the information that the firm have one or two new designs in hand for the show. The 3 h.p. lightweight twin engine which has been used on a New Hudson in one or two 1911 events will be one of the 1912 standard models. It has V cylinders with bores and strokes of 60 by 76 mm. 425 c.c. side by side valves, and is a miniature model of its parent, the 8 h.p. Although called 3 h.p. it will give more and should be successfully applied to lightweight models where the even torque and smooth running of a twin are often preferred to the more powerful impulses of a 500 c.c. single.
Gradior.
The 1912 Gradior engine, made by the Gradior Machine Co., Statford, has an engine of 86½ x 90 mm. and ball bearing crankshaft. It is designed for those who find a 500 c.c. engine hardly powerful enough, and should appeal to heavyweight riders and also sidecarists.

A.J.S.
The method of attaching the counter-shaft gear to the frame has been improved for next year.
As will be seen, the box has a flat top. with slight extensions at the side which fit closely on a special lug, thus preventing any tendency to twist. It is held in position by two studs which pass through slotted holes (to allow for chain adjustment) in the lug. The box itself has been rendered considerably more accessible by a slight alteration in the main casting. It is no longer constructed in two halves, but is cast in one piece, with a separate end plate. By unscrewing the thrust washer and removing this plate, the gears and shafts can be dismantled and re-erected by the merest novice.
Tormo.
The Tormo Manufacturing Company (67-68, Bunhill Row, London, E.G.), agents in Great Britain for the Sarolea motor cycle engines and F.S. ball bearings, will be marketing the same models as those sold during this year, and in addition will introduce a new 2 ½ h.p. single-cylinder engine, 66 by 86 mm. This is identical, with the exception of the stroke, with the 8 h.p. 1911 model, which was 66 by 72 mm.
New Rudge Variable Gear Model
We were recently privileged to inspect the new model Rudge machines which are nearing completion and have formed the opinion that these machines which have made such leaps and bounds in their comparatively short active life will be even more to the front in 1912, not that there are any striking departures in design to chronicle, but there are many minor improvements which cannot fail to commend themselves to the practical rider...

Rushmore Lamp Set.
The Rushmore Lamp Co. claim to have introduced the first of the searchlight lamp patterns with lens mirror – an event which happened some four or five years ago. It was not, however, until the present time that the company decided to place on the market a British made motor cycle head light, following as nearly as possible the successful lines of the Rushmore car lamp.
The lamp differs from the well-known car model in the following respects. Firstly, it is provided with a hood which is attached to the front of the lamp by means of screws, so that it may be easily detached, and a special fixing is supplied. A genuine Mangin lens is fitted, while special notice must be taken of the bracket clips. The face of the clip is circular, with small semi-circular projections cast on it, while depressions to correspond are cast in the boss of the lamp itself. Both projections and hollows are very small, so that a great number of various positions may be utilised. By undoing the wing nuts the lamp may be placed at any angle, and when the wing nuts are screwed up it will stay in the required position, the projections and hollows preventing any further movement.
The front door of the lamp, carrying the glass in sections in the well-known Rushmore style, is provided with a ventilator which gives out no back light, while the position of the burner is adjustable so that the light may be focussed to suit the wish of the rider.
One of the chief features of the Rushmore lamp is that it is entirely put together by means of screws, thus allowing it to be taken to pieces with the utmost facility.
The generator is simply and strongly constructed, and is much on the lines of their well-known car generator.
The water compartment A has a well formation, in the bottom of which lies the valve D, which can be easily removed for cleaning purposes, by detaching the nut B which holds it to its seating C.
The pace of the water-feed is controlled by turning the valve rod. The face of the valve has a small taper slot across it, at the broad end of which a hole is drilled into the centre, which is bored out to the bottom A corresponding hole is drilled in the seat C, so that by turning the valve first the small end of the groove comes opposite the hole in C, allowing a small amount of water to leak through, while a further turn causes the holes to be brought gradually in line, thus allowing a steady stream of water to pass. This, of course, is seldom necessary, unless for lighting up in a hurry.
Round the well lies an annular chamber forming a gas reservoir, the gas entering through holes in the screw plug F. From this reservoir the gas is led through a pipe G in the usual manner.
The carbide is carried in the receptacle H, which is perforated round the lower edge and fitted with a heavy gauge wire gauze bottom. The whole is carried and allowed to swing on the two pins K. fixed to the outer shell L.
The object of this is that the used carbide is lifted through the holes and gauze and drops into the outer shell. Thus when only part of a charge is used the waste may be emptied away and the lamp is at once ready for use again. The top and bottom halves are held together by the internally screwed ring M, a rubber washer N making a gastight joint.
Three different styles of carrying the lamp are provided for. Firstly, with the lamp in front and the generator close behind; secondly, with a slot behind so that the lamp may be fixed on to the usual type of lamp bracket; thirdly, there is a special carrier on the generator so that the generator may be fitted to a bracket attached to any convenient part of the machine.
A New Quickly Detachable Terminal.
The Rex terminal is one of the quickly detachable type and the invention of their draughtsman, Mr. Sargisson; it is both simple and neat. The cable is placed in the large hollow portion of the jaw, the wire is turned back and the jaw clinched. The terminal is now ready to spring on to the thread of any sparking plug central wire. After the terminal is sprung on the wire of the plug a nut may be added as additional security, but is not necessary. The inventor has had one of these in use for some time and has found it perfectly satisfactory. We believe the Rex firm are adopting it for 1912.

The total weight of the machine unladen will be 170 lbs., and with petrol and oil it will not exceed 185 lbs. It will be exhibited at Olympia for the first time next month and will be enamelled French grey.
A New Motosacoche.
The famous Geneva firm of H. and A. Dufaux have plumped for the long-stroke engine, the dimensions of the 1912 model being 64 by 90 mm. The most drastic change, however, is the wholesale rejection of the chassis or tubular frame, to which were fastened the engine and all the accessories. The engine will in future models be fastened direct to the cycle frame...

Buck.
The Buckman Engineering Co., of Sherwood, Nottingham, are experimenting with a light four-wheeled runabout.
A two-cylinder V engine of 90 mm. bore and 95 mm. stroke is employed, cooled by two fans which blow direct on to the cylinder heads and valve ports.
The engine is set across the frame, and behind it is placed a two-speed epicyclic gear. From this the power is transmitted through a universally-jointed propeller-shaft, enclosed in a torque tube, to a neat live rear axle, a spur differential gear being used. Contracting brakes are fitted to each rear wheel, while the makers tell us that by putting both gears into action at once a powerful transmission-shaft brake is obtained. The wheels are shod with 550 x 65 voiturette tyres, and Bosch magneto and Amac carburetter are employed. The machine we were shown had a tubular frame, but in future pressed steel will be used throughout. A bonnet and scuttledash, with two aluminium seats, are fitted. Steering is effected by worm and nut.
While in the works we were shown a three-cylinder rotary engine, with rotary valves. This engine was originally made for aeroplane work, but we hear that a smaller and modified type will shortly be produced for motor cycle work.
P.M.C.
Three new models will be marketed by the Premier Motor Co., of Birmingham. In each case the frames are made by the Rex Manufacturing Co., while the engines fitted are the 4 h.p. single-cylinder and 6 and 8 h.p. twin-cylinder J.A.P.'s.

C.C.R.-J.A.P.
The other day one of the partners of the firm of Smith Bros., Nottingham, called upon us with the luxurious sidecar which we illustrate, with the object of giving us a short spin. We found the sidecar most comfortable riding, the double C springs forming an ideal suspension. The 6 h.p. side by side valve J. A. P. is most effectively silenced, and the machine purred along on its top gear at well up to legal limit with an entire absence of vibration. The sidecar hood and screen are standard fittings on the C.C.R.

The Two-stroke Levis.
This interesting little machine is propelled by a three port two-cycle engine, and has been slightly redesigned for 1912. The new piston is designed with a partially domed head, giving a sharp uprush to the inlet gases, and a very clean sweep for the exhaust...

Hazlewood.
A new make of motor cycle for 1912 is the Hazlewood. It is a 2¾ h.p. medium weight. A J.A.P. engine with side by side valves is employed in conjunction with the Armstrong three-speed hub, giving gears of 5, 7, and 10 to 1...

Alldays Improvements.
Since we last described the Alldays motor cycle several improvements have been made, with the object of producing a more handy and comfortable machine. A domed top piston is now used, and slippers have been interposed between the cams and tappets...

Rudge.
A small point, illustrative of Rudge thoroughness, is found in the manner in which spare valves are protected by neat metal shields as shown in the accompanying sketch. Not only is the working face of the valve completely prevented from suffering damage by being put loosely into the too1bag with other hard objects, but the spring and cotter are also kept in position by a small tubular distance piece which also protects the valve stem from injury. The drawing shows the idea as applied to the inlet, that for the exhaust valve being similar, but, of course, larger.

Puch
We have already referred to the new arrival in this country – the Austrian Puch. The machine has been amended in design to conform to English ideas, and at the Show will have B. and B. carburetter, footrests, pedal-applied foot brakes, Bowden operated hand brakes, and a lower saddle position.
His Highness Prince Alexander Lubomirski is an enthusiastic owner of a 6-7 h.p. twin Puch and sidecar.
Rex.
The Rex Motor Mfg. Co. will market the following models in 1912 : 3½ h.p. Speed King or Tourist; 6 h.p. twin Speed King or Tourist; 4 h.p. Tourist single-cylinder, air of water-cooled; 4 h.p. De Luxe, single cylinder, air or water-cooled; 6 h.p. De Luxe twin-cylinder; 4 h.p. Sidette De Luxe, air or water-cooled; 6 h.p. twin Sidette De Luxe. The 4 h.p. is a new model introduced for next year's market, and has a larger bore than the 1911 3½ h.p. of 499 c.c. capacity. It will be dealt with in detail in our Show issues.

N.S.U.
The most radical alterations in the N S.U. designs will be found in the 3½ h.p. engine, 85 by 88 mm., 499 c.c. The prototype of this engine was first seen in England at the Tourist Trophy Race. The magneto is placed behind the cylinder, is of the latest Bosch enclosed type, and is gear driven. On the gear wheel nearest the engine-shaft...

A New Sidecar Stand.
Mr. J. Varley. 57, Stoney Lane, Sparkbrook, Birmingham, has sent us particulars of a sidecar stand which we illustrate. The stand is clipped to the sidecar axle and is put into operation by placing one foot against the leg of the stand at the same time pulling the sidecar back. It will be noticed on reference to the illustration that the top of the stand is provided with a spring and plunger. When the sidecar is supported by the leg it inclines at an angle of seven degrees, thus making a support, and when out of use the spring prevents any possible chance of the leg falling. It will be exhibited on the Calthorpe stand at Olympia, as will the Forward sidecar which will be fitted with a canopy hood, luggage carrier, tyre carrier, petrol carrier, and refinements in the way of toolboxes, etc.
Another Two-speed Hub Gear.
The broad principle claimed for the Thornton two-speed hub is that a free engine can be obtained without disturbing the mechanism which operates the high or low gear. The clutch consists of a phosphor bronze ring D which is split and engages the hub shell H by means of cone E. pinion carrier C and lever F2 working on spiral F1. The normal ratio is obtained by locking gear wheel B to the belt hub K through the intermediary of clutch D and pinion carrier C, the gear wheel B being locked to the carrier by four pegs or keys. The low gear position is arrived at by sliding B along the shaft until it engages with pegs or keys L. the reduction in gear being effected through pinions J. On the underside of G is attached the free engine mechanism. This consists of teeth cut on plate G engaging with corresponding indentations on D and C; when the clutch ring is contracted the engine can be pedalled with rear wheel resting on the ground with either high or low gear engaged. The makers, W. J. Glover and Co., 32 King Street, Leicester, claim that the gear is absolutely proof against damage through bad handling.
