CARRIAGE AND APPARATUS OI'ERABLE FROM A DISTANT STATION.

Specification of Letters Patent.

Patented July 17, 1917.

Application filed December 28, 1915. Serial No. 69,100.

To all whom it may concern:

Be it known that I, E GENE SCHNEIDER, a citizen of the Republic of France, residing at Le Creuzot, France, have invented a new and useful Improvement in or Relating to Carriages and Apparatus Operable from a Distant Station, which is fully set forth in v the following specification.

for instance with a collecting .also adapted K with the improved carriage part of the invention.

- particularly exerted from This invention has for its object to provide an improved carriage constructed more for being actuated by traction a distant station for the purpose of causing it to travel over variable distances and over very rough and uneven ground, andif desired, being finally returned tothe said station by traction in the reverse direction. The improved carriage is adapted for transporting at a distance an agricul-' tural implement (such as a machine for picking roots, beetroots and the'like, combined vessel). It is to bring up to a variable distance from a battle front or firing line a war 7 engine adapted to work by dropping, ejecting, throwing, time explosion, etc.

The problem of transport at a distance and of travel over very rough or uneven ground by simple traction-exerted at the starting station, has been solved by the pres-' ent invention which consists in the hereinafter described improvements.

An embodiment'of the invention applied to a particular war engine is illustrated by Way of example in the accompanying drawings. The combination of this war engine also constitutes In the drawings Figure 1 is a longitudinal elevation;

' plan corresponding thereto;

1g. 2 is a Figs. 3 and 4 arerespectively a plan and an elevation drawn to a larger scale of automatic apparatus for'discharging a jet of inflammable liquid and igniting it at a determined distance in front of the engine.

As shown, the improved apparatus comprises a carriage F, the body of which may of course vary according to the purposes in view, and which in the example shown, is designed to discharge at the place of arrival a powerful jet of petrol, petroleum or other inflammable, liquid. The carriage proper, comprises on each side, in addition to the front wheel A and the hind wheel B, an elevated wheel 0. Over these three Wheels A, B, C, which are provided with side band or belt D flanges or cheeks, there is stretched a metal carrying a series of blocks of Wood or other suitable material. The hind wheels B are connected to a drum or wheel H journaled in brackets H fixed to the body of the carriage, by means of gearing, such as the chain pinions I, J and the chain K. L M is a cable adapted to be wound on the drum H. For the purpose of increasing the adhesion of the cable, the latter is fitted with a tightening pulley or pulleys. For this purpose the cable after having passed over a certain portion of the circumference of drum H, is led around a pulley N mounted on an axle carried by the brackets H and thence it can be wound once or twice more around the drum H.

The Winding of the cable on the drum Q which is provided with a crank Q causes the drum H to rotate and the carriage to move forward. Meanwhile, the cable is Wound off the drum P on which it Was wound. When it is desired to cause the carriage to move backward, the crank Q is placed on the axle of the drum B, and the cable is unwound from the drum- Q and wound on to the drum P. The drums P and Q may be mounted on axles provided on a Windlass or any other suitable support already located at or, brought crating station.

en the wheels are caused to move B are rotated, the belts along, -and as the blocks to travel forward. If the carriage should happen to strike an obstacle with the portion of the belts situated between the wheels A, the blocks will grip the obstacle and will lift the front part of the carriage over the obstacle. The carriage in following the contour of the ground over whichit passes in its travel,rolls on the lower stretches of the belts comprised between the wheels B and A, or on the stretches comprised between the wheels A and O.

In order that these effects shall be. pro duced, the apparatus must satisfy certain conditions that result from the following technical considerations:

Let

6 represent the traction exerted upon the cable M,

k the radius of the drum H,

z the radius of the pinion I,

j the radius of the pinion J, and

b the radiusof the wheel B;

C and the wheels tact with the rolling then the tangential stress produced by consurface will be:

Now, since the force which opposes the forward movement of the carriage when it is rolling over the ground is Pm, P being the total weight of the carriage and 'rthe coefficient of rolling (taking the gradient into consideration), and if, as has been assumed, a pulling force t is exerted in the reverse direction to the forward travel of the carriage, the resistance opposing the advance will be P.1'+t.

Therefore, in order that the carriage shall be able to move from the point of traction upon the cable, it will be sufficient that that h j T73 that is to say, there must be a step-down in the transmission; in other words the speed of the cable must be greater than that of the carriage.

In order that the wheels shall not skid, it is necessary that the force acting tangentially on the wheels, shall be smaller than the adhesion. It is necessary therefore that 77 being the load on the driving part, and f the coeflicient of sliding friction over the ground or It will be seen that if the rolling is difficult, as for instance on plowed land, when 1' is not very much less than f, it will be necessary that p shall be a large fraction of P., that is to say, the whole of the load or almost the whole of the load must be on the driving part and f must also be as large as possible.

This result is assured by connecting the wheels A, B by means of the belt provided with a series of projections E. In these circumstances the whole of the weight P will come in aid to the adhesion to the ground and the coefficient is increased by the projections. Further, 1' is diminished because the wheels instead of rolling on the round, roll on a track constituted by the belt which bears with a large surface upon the ground. This arrangement also diminishes the effect of the unevenness of the ground, and thus diminishes also 1'. These belts may be made of metal for the purpose of reducing still more the resistance to rollmg.

Instead of belts, cables, chains, rollers or any other devices may be used that will fulfil the same purpose.

Similarly, any desired means may be employed such as chains, belts, endless screws, etc. for transmitting the power from the driving drum to the driving wheels.

The function of the elevated wheels C is, as already stated, to allow of passing over high prominences. The projections E instead of being formed of blocks of wood, may be formed of angle bars riveted transversely on the belt.

The invention also consists in the combination of the improved carriage with a particular engine, one constructicaal form of which is illustrated by way of example in Figs. 3 and 1 of the accompanying drawings. In this example the body of the carriage is constituted by a tank filled with an inflammable liquid such as petrol up to a suitable level, the space above the petrol being occupied by compressed air.

The tank is provided in front with a nozzle or jet device S fitted with a tap T.

The apparatus for discharging the petroleum jet and igniting it at the moment when the carriage has reached a predetermined distance which can be adjusted at will, may for instance be as follows:

One of the wheels C carries as a projection from its inside cheek, a stud or pin which at each revolution of the wheel causes a star wheel V to advance one tooth. This star wheel V is carried by one of the ends of a screw-threaded rod W journaled in a suitable support carried by the body of the carriage or by the wall of the tank. The other end of the rod W engages in a nut X which can slide but cannot rotate. The

rotation of the rod W will therefore cause the nut X to slide longitudinally in the direction of the arrow. The lever T of the tap T bears on a flat portion X formed on the nut X and is subjected to the action of a spring T that has a constant tendency to open the tap.

When the nut in its travel moves from under the lever T which will occur at the end of a period of time determined by the starting position given to the nut, thetap will open and will allow the inflammable liquid or the like to escape under pressure.

The apparatus for igniting the jet of liquid may be constructed in various ways. According to one way, a percussion cap Y is arranged on a fixed support in the path of the lever T so as to be struck by the latter when, by the action of the spring T.

it has arrived at theend of its opening stroke into the position shown in dash and nectcd to the traction apparatus can may comprise only one stretch M of hauling wheel mounted on dot lines in Fig. 3. This percussion cap will ignite a wick Z,'one end of which is conpercussion cap holder, While its other end terminates close to the issue aperture for the jet.

The carriage, whatever may be the use for which it is intended, may be provided with accessories, more particularly scrapers for cleaning the inside surface of the belt I). Intermediate rolling or guiding drums or wheels may be provided between the wheels A and B and also between the wheels A and C.

One of the main features of this present invention is the apparatus whereby the carriage can travel over the contour of the ground on different bands or belts. This feature is also present in the arrangement of the series of-wheels mounted on axles at different levels and connected together by a common band or belt which envelops them after the manner of a driving belt, and carries also projecting adhesion studs or projections.

This particular arrangement may obviously be employed not only in combination with the hereinbefore described apparatus for propulsion by traction, but also with any other suitable means of propulsion. It may for example be adapted to a motor-driven vehicle. 4

In the case ofa carriage with belts as employed with the hereinbefore described traction system, it may be advisable in some cases to release or abandon the said carriage at the point of arrival. In such a case the be simplified and remainder of the cable, the whole of the kept wound on the length of the cable being drum H.
