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, in order to give 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 m. 55 or 2 m. 75; width, 0 m 80. Outdistance apron with the tangent with the aft wheels: 1 m. 87 or 2 m. 07.
Engine. -
The engine is with 4 run cylinders of one only block. The cylinder bore is 90 m/m and the travel of the pistons of 120 m/m. The cylinders are excentric in order to improve the output. The aspiration and exhaust valves interchangeable and are ordered by only one camshaft. Their visit is simpler.
The crankshaft out of steel Nickel-chromium with high strength, soaked and rectified, turns in strong ball bearings fixed in the aluminum casing. This casing rests by four legs well veined on a false pressed frame, and does not comprise a median joint, because it is of only one part. This provision as well as the molding of only one block of the 4 cylinders gives a very great rigidity, while forming a unit very little cumbersome.
The carburettor, of the mark Zenith, is rigorously automatic and makes it possible 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 Bosch magneto, with high voltage, models armoured.

Cooling is with water circulation per thermosiphon. Piping, of great section, is reduced to the possible minimum length, in order to not offer any resistance to the circulation of water. A ventilator, provided with a belt tightener, produces a strong air drainage has, through radiator has great surface placed in front of the frame.
Le greasing of the engine is internal, entirely automatic and fool-proof. The driver does not have to be occupied some, if is not to replace the oil provision when it is exhausted. Here how it is assured. Under the casing is an aluminium tank which is fixed by means of bolts. This tank is divided in two stages by a horizontal partition the higher stage itself is divided into 4 compartments corresponding each one to a cylinder U driving and years which come to plunge the big ends. The lower stage forms oil tank than one fills by a special pipe, quite accessible. A small gear pump, involved directly by the end before camshaft , aspires the oil of this tank and drives back it in the compartments - superiors. These compartments are provided each one with a overflow by which the oil excess turns over to the lower tank .The splashing of the big ends in oil is thus absolutely regular, since the oil level in the 4 compartments remains always the same one. The greasing is not influenced by the downward inclines and remains such as it was regulated with the assembly, until complete exhaustion of the provision 'oils versed in the tank. A simple pressure gauge, connected on the discharge pipe of the pump, indicates to the driver that the greasing functions well, and informs it as soon as the oil reserve starts to become exhausted.
Trorpedo-Limousine on frame 16/20 HP (extra-long).
This lubricating system, such as we established it, functions very regularly and gave us the best results. By unbolting the tank oils, one can visit the big ends and examine all the interior of the engine, without having to remove it frame.
The engine and its accessories, magneto, carburetor, ventilator, system lubrication, form a unit released and very simple, of which all the parts are quite accessible and easily dismountable, without cumbersome pipings or linkages. Its operation is soft and quiet, and its excellent output.
Clutch, shifting of speed,
tree with Cardan joints. - These bodies are absolutely similar to those of our type 12/14 HP; we thus request our readers to refer to descriptions which we gave of these bodies pages 11, 12 and 13 of this catalogue.
Bridge postpones with towards
The back bridge of our type 16/20 HP has the effect of having the rockets slightly inclined on the horizontal one, i.e. it has towards, which makes it possible to give set to the wheels. The advantages of this provision are well-known and its influence on the conservation of the tires is certainly very important. Unfortunately the realization of such a system of bridge is not without presenting certain difficulties and its cost price is much higher than that of an ordinary bridge without towards. Nevertheless, for more than four years that we build this system of bridge, our customers have shown themselves some so satisfied, as well from the point of view of the robustness as with that of the saving in tires, than we did not hesitate to continue to provide our frames with them, in spite of his high cost price.
The bridge is made up absolutely in the same way that that of our type 18/24 HP, described page 26 of this catalogue, and its connection with the frame is identical.
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 815/105.
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 behind 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.
