To all whom it may concern.-

Be it known that I, EMILE BA'rIssE,a citizen of the Re ublic of France, residing in Lyon, France, ave invented certain new and useful Im rovements in Starting Devices for Motors, 0 which the following is a specification. a

This invention relates to mechanical devices for starting explosive-motors.

The invention has among its objects to provide a starting device which is particularly applicable to motor-cars and which is enerzed by the motor itself after the latter has een started.

The invention also contemplates the use of fluid-pressure as a motive power, thereby doing away with the use of springs -or similar devices which are subject to rapid deteriora tion.

A further object of the invention is to providea starting device so mountedwith respect to the engine-shaft that the device may be operated so asto start the motor, tobe energized by tha'same, or to be moved out of cooperative relation with said shaft by means, of a single lever, which in case of a motor-car can'be operated from the drivers seat.

With these and other ends in view the invention consists in the novel features and combinations of parts to be hereinafter disscribed and claimed. 1

In the accompanying drawings, in

the same parts'are denoted by the same reference characters throughout the several views, Figure 1 is a front elevation of the improved starting device, showing the. same mounted upon a motor-vehicle. Fig. 2 is an enlarged side elevation of the device, certain parts of the motor-vehicle being removed for the sake of clearness and Fig. 3 is a front elevation of the starting device, the front plate being removed and-certain parts shown in section.

Referring to the drawings, A denotes the engine-hood of a motor-vehicle, and m the engine-shaft, which is disposed beneath the hood in the usual manner and has keyed'to its forward end a gear-wheel 1. To the front or face of the hood A and above and slightly to one side of the engine-shaft m are secured Extending forwardly from the lower edges of the front plate O are spaced brackets F, having sleeves at their forward ends, which embrace a rod G, extending between the forward ends of the vehicle-springs, as shown. A plate D, similar to the plates B C, is mounted in upright position across the brackets F, and between l the platesC and D are su ported the operative parts of the improve starting mechanism. This mechanism embodies a cylinder 1 d, extendin across the front of the hood in horizontal irection and supported at either side between the plates by means of bosses and screwnuts or in any other suitable manner. Leading from the head of the cylinder (1 which is farthest from the engine-shaft m is a pipe bflcontrolled by an oscillating cock or valve 1), operated by a crank-arm a and other mechanism to be presently-described. The ipe b is in turn connected to a pipe 0, which is referably made of flexible material, and t e latter pipe in turn connected to one head of a cylinder b, which is shown in Fig. 3 and in practice may be mounted upon any suitable part of the motor-car. A pipe (1 leads from the cylinder 1) at the end opposite the connection of the latter with the pipe 0, and said pipe (1 is in turn connected witha suitable receiver or reservoir a, as illustrated in Fig. 3. This receiver in practice is also mounted on or stored within any suitable part of the motor-car. For controlling the communication between the receiver a and the pi e d a valve r of any suitable type is provi ed.

In carrying out the invention the receiver a is filled with a highly elastic gas designed to .act upon a piston c, which is freely movable throughout the length of the cylinder-b. This piston acts in turn upon a body of liquid which is contained in the cylinder band which may be forced by said piston into the pipe 0 by the valve b- :when. the same is opened and thence into the cylinder (1, where it acts upon a piston e. Secured to the side of the last-named piston, which is not in con tact with the liquid, is a gear-actuating member, illustrated as a rack f, which is of considerable length and is movable-through an opening in the cylinder-head nearest the engine-shaft. The teeth of the rack f are arranged at the lower edge of the same and are ting mechanism to be described hereinafter. Between the rack f and the piston e a cushioning or lost-motion device m is arranged for reducing the shocks upon the transmitting mechanism.

Above the engine-shaft and pivoted between the plates C and D at a point slightly below the axis of the cylinder d is a hanger or designed to act upon a coupling or transmit-v at the'rear of the gear-wheel 70, said pivot-pin 0, upon which said hanger is pivoted, passing through the same at the intersection of the legs or branches thereof. -At a point above the pivot 0 said hanger is enlarged to form a segment W, provided with a segmental slot by which the hanger is guided over a pin 0, extending from a roller 0 disposed at the rear of the carrier and movable in contact with the upper edge of the rack f, so that said rack is efficiently guided and maintained against upward stress irrespective of the pivotal position of the hanger.

J ournaled upon the pivot-pin 0 at the rear of the hanger r s t is a gear-wheel g, meshing with the rackf. A larger geanwheel h is also j'ournaled upon the stud or pin 0 at the rear of the hanger, and said ear-wheel h meshes with a small gear-wheelIc, rotatable about a pin p, carried at the extreme end of one of the divergent hanger legs or branches. A large gear-wheelt' is also rotatable about the pin p w eels bearing a fixed relation to each other. A pin q, similar to the pin p, extends rearwardly .from the end of the other hanger-leg and has rotatable about the same a small gear-wheel 7', meshing with the large gear-wheel 'i. The train of gears described is so arranged upon the hanger that when the latter is oscillated on its pivot. either of the Wheels i 1' may be brought into mesh with the gear L upon the motor-shaft,-depending upon the direction in which said hanger is moved.

In order to effect the oscillation of the hanger 1" s t, one of the lower legs thereof hasconnected thereto a connecting-rod it, which is pivoted at n to a system of levers X Z, fixed to a spindle V, extendin between the supporting-plates. The lever J is connected in any suitable way to a lever, (not shown,)

' It is therefore obvious that when the hanger is shifted in either direction the crank-arm a will be shifted, as indicated by the arrows 3 and 4,and consequently the valve b will be opened; In the position shown-that is to say, when the train of gears carried by the hanger is out of cooperative relation with the gear on the motor-shaft-said valve is closed,

. its crankarm being disposed vertically.

The operation of the improved starting device is essentially as follows: Supposing the parts to be in the position shown in Fig. 3 and it is desired to energize the device from the motor, which will be considered as being in operation, the lever Z is so actuated by the termediary of the connecting-rod u, the rocking of the crank-arm a in the direction indi-' cated by the arrow 4 and the consequent opening of the valve b, which thus permits t e liquid in the cylinder (1 to escape into the pipe 0 under the pressure of the piston e. The liquid driven out of the cylinder (1 by said piston then enters the c linder b and under the pressure generate by the motor forces the piston ctoward the left, as indicated in Fig. 3, so that the highly-compressi ble gas filling said last-named cylinder at the side opposite the liquid is driven into the pipe d and thence to the receiver a, where it is highly compressed. The valve or stop- ,cock 1" is then closed in order to retain the gas in compressed condition in the receiver a.

The lever Z is then actuated, so that the hanger is shifted into its median positionviz., so that its gears are out of engagement pressed condition in the receiver a, a small amount being diffused in the pipe (1, as will be understood. When the motor has been stopped and it is desired to start the same, the operations previously described are re-' versed. The lever Z is thrown in a direction opposite to that first named, so that the gearcarrying hanger will be shifted to the left, as shown, and the small gear 1' will engage the motor-shaft gear Z, which in this case is the driven member. It is obvious that when the hanger is shifted as-indicated the crank-arm a of the valve bwill be shifted, as indicated by the arrow 3, whereupon the liquid in the cylinder 1) and pipe 0' will be driven by the gas in the receiver a, the cock r of which has previously been opened, into the cylinder (1 with a degree of force corresponding to the pressure of the gas. The liquid accordingly acts upon the piston e of the rack-cylinder d and forces the rack f outwardly, thereby transmitting motion to the train of gears carried by the hanger and from the gear 7', to which motion was last transmitted to the motor-sliaft gear Z. This last-named gear is therefore rotated at considerable speed and the motor started through the rotation of its shaft m. As soon as the starting operation has been completed the hanger which carroorio

legs, a train of gears,

By causing the compressed or liquefied gas or other elastic fluidtoact upon the piston and rack f through the intermediary of'a nonelastic fluid the advantage is obtained of suddenly suppressing all ressure in the cylinder (1 as soon as the va ve b is closed, which would not be the case if the gas acteddirectly u on the piston e by reason of the expansion 0? the former.

Having thus described my invention, I claim as new and desire to secure by Letters Patent. j
