Description of the frame 12/14 HP.

Frame. - The frame itself is out of sheet steel pressed with the press. It is narrowed with before making it possible to turn in a very reduced circle, and slightly raised with the back, so giving more freedom to the springs.
The frame rests on its axles by the intermediary of very long springs and with weak arrow giving a very soft suspension. The springs postpones are of the type with stick. All the ends of the springs are provided bolt-greasing devices. Principal dimensions of the frame are as follows: Length available for the body, 2 Mr. 35 or 2 Mr. 55 ; width, 0 Mr. 80. Outdistance apron with the tangent with the aft wheels: 1 Mr. 67 or 1 Mr. 87.
Engine. - The engine is with 4 run cylinders of only one block. The cylinder bore is 75 m/m and the travel of the pistons of 120 m/m. The cylinders are excentric so improving the output and decreasing wear. The valves are ordered by only one camshaft. The suction valves are placed above the exhaust valves and are ordered by tumblers. The stems of the valves, their springs, the push rods and the stems of ordering of the tumblers are locked up. A large door of visit out of aluminium, maintained by two butterfly nuts, very easily allows y to have access.
In the same way, the tumblers are locked up in a cast iron casing, easily dismountable because it is maintained only by two nuts.
The axes of the tumblers are hollow and are provided with a head forming oil tank.
The crankshaft, out of steel with high-strength, soaked and rectified nickel-chromium turns in broad bearings out of bronze furnished with antifriction metal, fixed in the aluminium casing. This last rests by 4 legs well nervées on a false frame.

Engine 12/14 HP “Springuel”, side carburettor.

The carburettor of, the mark “ZENITH , is rigorously automatic and allows to obtain a very reduced consumption. It is fool-proof, because it comprises neither arises, nor valve of air; it gives to the 'engine a great flexibility, and ensures of the very frank and very clear recoveries, without any failure.

Lighting is done by magneto BOSCH, with high voltage, models armoured:

Greasing of the engine is internal, entirely automatic and fool-proof. The driver does not have to be occupied some, if this N is to replace the oil provision when it is exhausted.

Here how it is assured. The lower part of the casing is consisted an oil tank than one filled by a broad pipe provided with a metal filter. A float provided with a stem which appears with the higher part of the casing indicates the quantity of oil contained in the tank. A small pump, ordered by a vertical shaft receiving its movement of the tree with edges via two helicoid pinions, draws the oil of the tank and drives back it in a slope which runs all along the engine inside the higher casing. This pump is located at the lower part of the oil tank; it is thus always charges some and is not likely to be defused.

Engine and Clutch frame 12/14 HP “Springuel”,

The oil driven back in the slope, falls, by openings suitably laid out, in 4 basins, arrivals of cast iron with the casing, and in which come to plunge the small spoons located under the heads of the blue ones. The height of these basins was regulated once for all, in order to ensure a suitable greasing, without excess. As of the level necessary is reached, the basins overflow and oil in excess falls down in the tank; the greasing remains thus absolutely regular until complete exhaustion of the oil provision poured in the tank and is never influenced by the downward inclines. A simple pressure gauge, connected on the discharge pipe, indicates to the driver that the greasing functions and informs it as soon as the oil reserve starts to become exhausted. Lastly, the channels still leave the slope of repression and lead oil to the stages of the crankshaft, with those of the camshaft and at all the places to be lubricated.

This system gives any safety and gets large saving in oil thanks to the regularity of the greasing which makes it possible to regulate consumption with bare essential. It is moreover very clean and contributes to give to the engine an aspect Net and released in consequence of the absence of any external piping.

A broad drain plug makes it possible to empty the oil tank.

The engine and its accessories, magneto, carburettor, ventilator, system lubrication, form a unit released and very simple, of which all the parts are quite accessible and easily dismountable, without cumbersome piping or linkages. Its operation is soft and quiet, and its excellent output.

Clutch. - The clutch is with opposite cone, furnished with leather. It is the simplest type, most robust and surest. When a clutch with leather is studied and built well, it gives perfect results and an absolute progressiveness. The clutch of our car 12/14 HP answers all the requirements; it is of a progressiveness such as one can easily start in the fourth speed.

The apparatus is composed of a cone female reversed, consisted a cast iron C crown fixed at the wheel V of the engine. Male cone A, out of aluminium furnished with leather, is bolted on a plate P finished by a casing D which can turn and slide on the prolongation B of the crankshaft of the engine. The male cone is centered thus perfectly compared to the cone female, condition essential with the correct operation of the apparatus..
      

 

The spring of clutch R takes support, on the one hand on the wheel, on the other hand on the plate P by means of a thrust ball bearing E. It results from it that this clutch gives moving any reaction, neither on the engine, nor on the shifting of speed; it is thus rigorously balanced.

Disengaging is obtained by the action of the pedal on a ball bearing 1, contained in a bronze F cage, by the intermediary of forks not illustrated on the drawing - the effort necessary to disengaging is very weak, so that the operation is very soft and much easier than with the metal clutches.

The clutch is joined together with the shifting of speed by two very neat cardan joints, in order to avoid the accidental deformations of the frame. The greasing of the first joint of the Cardan joint is ensured by a greasing device Stauffer G, which lubricates at the same time the casing D, the bearing of disengaging 1 and the thrust ball bearing E.

The second joint of the Cardan joint is lubricated with the means of a syringe belonging to the tools of the car and which one screws on the ring of the Cardan joint. This last contains rooms which fill of grease that the centrifugal force drives out little by little in the articulations.

Thanks to these provisions, the maintenance of this clutch is excessively simple. Its disassembling is also very easy and is done without touching neither with the engine nor with the shifting of speed.

Shifting of speed. - The box speeds is with two wandering trains and comprises four speeds before and a reverse gear ordered by only one lever. The fourth speed is in direct catch. The walkman not in service is engaged automatically, in order to what it cannot come in catch fortuitously. The trees of the shifting of speed are very short and of large diameters, so that they cannot vibrate. They all are assembled on ball bearings. All the gears are out of steel B. N. D. whose resistance is well-known.

 The casing itself is of only one part, joint less, which avoids any oil leakage and gives a very robust unit. The movement of ordering of the walkmans are in the box even shifting of speed; the order is thus very simple and fool-proof.
With the back of the shifting of speed is the foot-operated brake consisted a steel drum, broad and of large diameter, surrounded by 2 steel jaws also furnished with special cast iron band . Two double helicoid cams make it possible to bring closer these jaws and to tighten the pulley vigorously. The wear of the cast iron bands is caught up with very easily by tightening the nuts of adjustment of the cams. The brake is very powerful and of an easy adjustment.

The shifting of speed, the brake and its adjusting device, are entirely located under the floor before car; they are thus always easy to visit. It is an advantage on the frames in which the shifting of speed is under the operator's seat, because it is then necessary to remove the body to visit it suitably and to lie down under the car to regulate the brake. And the adjustment accessibility of a brake is a guarantee of very large safety, bus too often and in spite of the importance of this body, his visit is neglected because it is badly placed, and his adjustment because it is inconvenient.

 Tree with Cardan joints. - The transmission of  the shifting of speed to the back crane, is done by a tree provided with each one of these ends of an universal joint. Each one of these joints comprises 2 hollow axes, into which one introduces grease intended to lubricate the articulations. For this purpose, each of the two joints is provided with a threaded bushing which one removes and in the place of which one screws a grease gun, delivered with each car, then one stuffs grease until refusal; the two axes of each joint fill thus by only one operation, because they communicate between them by their medium; after which one screws up the stopper on the axis. When the car works, the centrifugal force drives out little by little grease in the articulations, which prevents at the same time mud from penetrating there.

This greasing is automatic and gives excellent results; it is enough for a normal use, to fill the axes with grease, all the 3 or 4 weeks.

 Back bridge - the back bridge of our type 12/14 HP is consisted a steel casing, on which two conical forged steel tubes are firmly bolted. A tensioner arms the whole and is opposed to any inflection. These parts form actually a hollow axle on which the wheels turn, gone up each one on two ball bearings. There is thus no door with forgery and the trees of the differential which pass inside the tubes and which involve the wheels by means of claws adjusted in the hubs, are not inflected any, but work only with torsions It is exactly the same provision as that adopted in our more powerful types.

       

The trees are out of nickel-plated steel the shells of the forged steel differential, it driving pinion and the bevel wheel out of steel B. NR. D., just as all the pinions of the differential; all the bearings are assembled on balls with bearing thrust ball adjustable; in short the unit constitutes a very robust whole and of a particularly neat execupion.

Connection of the bridge to the frame. - The bridge is connected to the frame by the springs postpones, which are very broad and are used as poussarts. The reaction of the bridge is balanced by a single strut, out of buckled plate, whose end finished in kneecap, is locked up in a box provided with springs shock absorbers.
The whole is lubricated by only one greasing device with consistent grease located outside the frame, therefore quite accessible.

Front axle. - The front axle is out of forged nickel steel, of section in double T. The rockets, very robust, are provided with ball bearing.

Tires. The four wheels are provided with rims for tires of 760/90 or 765/105.
On request, we provide our frames with wheels for tires of other dimensions

Direction. - The direction with endless screw is irreversible It is provided with shock absorbers with kneecaps; all the parts out of forged steel and are strongly proportioned, in order to give an absolute safety. The bar of connection of the direct wheels is in back of the axle, protected well from the shocks.

Brakes. - The car is provided with three brakes; one on the shifting of speed, ordered by a pedal, and two on the aft wheels, ordered by a hand lever. These three brakes are metal and very powerful, though progressive. Their adjustment is extremely simple and is done very quickly.
The brakes on wheels are with balanced tightening, avoiding the dangers of skid resulting from an unequal braking on the two wheels. They with interior tightening and are entirely contained.
