To all whom it may concern:

Be it known that I, FRIEDRICH BALAssA, of Budapest, AustriaI-Iungary, a subject of and whose post-oflice address is Rezso tr No. 1, Budapest, X, Kingdom of Hungary, Austria-Hungary, have invented a new and useful Improved Starting Device for Internal-Combustion Engines, of which the following is a specification.

I This invention relates to starting devices for internal combustion engines.

The object of the present invention is to provide means for starting internal combustion engines with ease and certainty with the assistance of a single workman.

In the accompanying drawings, Figures 1 and 2 show, by way of example, the improved starting device applied to a motor vehicle or portable engine; Figs. 3 and 4 show the device in two positions on a larger scale, and Figs. 5 and 6 are detail views hereinafter described.

In carrying out the invention a toothed gear a is provided on a shaft a rotatably supported in the frame of the engine. Pivoted on the shaft of is a forked lever e in which is journaled the shaft 0 of a gear a engaging with the gear a. Secured to the shaft 0 of the gear a is a sleeve or pulley d which is covered with, or is made of vulcanite, wood, leather, india-rubber or any other suitable material and which can be pressed against the rim of the fly-wheel of the engine by rotating the forked lever 6 around the shaft a On the frame of the engine-is'provided a bracket j. A lever is shown in end elevation in Fig. 5 and in side elevation in Fig. 6 has a projecting pin 70 which engages in a horizontal slot j in the bracket j and a pin 70 which passes through an orifice in the lever e. Loosely mounted on said pin 70 is a hand lever f having a pin f which passes through a concentric slot in the lever c and is adapted to engage with the side of the lever is.

k is a rod mounted to slide in the bracket j and having its end in proximity to a lug h'which is mounted on the cam shaft of the engine.

In order to start the engine the workman pumps or sprays with a small starting pump m a portion of fuel into the explosion chamber and then lifts the hand lever f into the position shown in Fig. 3. The rotation of said lever on its pivot 70 causes the pin f to engage with the side of the lever is and force it to the right so that the pin 10 moves to the right hand end of the horizontal slot 7' this causes the pin is? to move downward a little and rotates the lever e on its pivot a so as to press the pulley cl against the rim of the flywheel g. The crank b is then rotated by the workman whereupon through the gears a and a and the pulley cl which engages frictionally with the flywheel g' the latter is set in motion. The movement is continued until the piston reaches the inner dead'point. At this moment the fuel previously sprayed through the starting pump m and finely diffused as a result of the compression in the cylinder of the engine is ignited by a spark due to the magneto and the first explosion follows. At the same time, that is to say at the same moment that the spark occurs, the rod k is pressed downward by the lug and engaging with the side of the pin 76 causes it to move in the slot y' tion that as soon as the engine causes an accelerated movement of the flywheel due to the first explosion the pulley d is automatically disengaged from the rim so that no movement will be transmitted back through the gears a a to the handle 5 and any possibility of a shock or ar to the workman is avoided.

The device can readily be applied to any existing stationary or portable engine if desired.

What I do claim as my invention, and de sire to secure by Letters Patent of the United States, is

1. The combination with an internal combustion engine having a flywheel, of a pulley, a hand crank and gearing for rotating said pulley, manually operated means for forcing said pulley into frictional engagement with the flywheel, and means for autov the end of said lever, apin on said crank en- 7 matically disengaging said pulley and flywheel at the moment when the first explosion occurs.

2. The combination with anvinternalcom-i bustion engine having a flywheel, of a pulley, a hand crank and gearing for rotating said pulley, a lever on which said pulley is mounted journaled co-axially with the hand crank, manually operated means for'rotating said lever so as to force the pulley into frictional engagement with the flywheel,

and means for automatically disengaging said pulley and flywheel at the moment when the first explosion occurs.

3. The combination with an'internal combustion engine having a flywheel, of a rotatable pulley mounted on a lever pivoted to the frame of the engine, a crank pivoted at gaging-in a slot in a fixed part of the engine, manuallyoperated means for moving said pin in said slot to rotate the lever on its pivot and force said pulley intoengage ment with the flywheel, and means operating automatically when the first explosion occurs to move said pin in the opposite div rection soas to withdraw the pulleyfrom 4. The combinatlon with an'internal combustion 'englne having a v flywheel, of a Copies of this patent may be obtained for 5. The combination with an internal corn-V bustion'enginehaving a flywheel, ofa shaft journaled inthe engine frame, a lever pivoted on said shaft, a pulley rotatably mounted on said lever, va hand lever" pivoted on said lever,a pin on said hand lever proj ecting through a slot on said lever, a crank also pivoted on said'l'ever co-aXially with said hand lever and adapt'edto be engaged f by the pin 'on said handlevena pin on said crank adapted to move'ina slot in the frame, a rod slidably supported on said frame adapted to engage. with the pin on said crank and a lug on the cam shaft of the en- 7 7 inc for o eratin said rod when i ition occurs. a a In testlmony whereof I have hereunto set my hand 1n presence of two subscribing w1tnesses; l
