CHARLES P. SKUBLIN, OF DETROIT, MICHIGAN.

STARTER FOR EXPLOSIVE-ENGIN ES.

Application filed February 17, 1916.

To all whom it may concern Be it known that 1, CHARLES P. SKUBLIN, citizen of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented a certain new and useful Improvement in Starters for Explosive-Engines, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this I that no material change need be made in the latter to adapt it for the installation of the device.

Other advantages and improvements will hereafter appear.

In .the drawings accompanying this specification:Figure 1 is a front elevation of the device, showing the pawl engaging the teeth of the internal ratchet wheel, as when starting the motor. Fig. 2 is a horizontal sectional view through the device indicating parts in elevation, and in dotted lines, a portion of an engine crank shaft. Fig. 3 is an elevation of the device similar to Fig. 1, in-

dicating the ratchet pawl in released posi- I tion, as when tripped by its weighted arm upon contacting with the frame or chassis. Fig. 4 is a front end elevation of an automobile with parts removed, indicating the device installed, and means for manually operating it from the drivers seat. Fig. 5 is a fragmentary diagrammatic plan view of the frame of an automobile with the device in position.

Referring now to the letters of reference placed upon the drawings :-A, denotes the crank shaft of an internal combustion engine ;-B, indicates an internal ratchet wheel Specification of Letters Patent.

and pulley, secured to the crank shaft by a transverse pin C.

B, designates a projecting stub shaft preferably integral with the ratchet wheel. D, indicates an annular member mounted upon the stub shaft 13, having a ratchet faced end (Z, to receive the usual crank arm E, (indicated in dotted lines) for manually cranking the engine.

(Z, is a transverse pin to secure the annular member to the stub shaft.

F, denotes a lever arm having a hub portion sleeved upon the annular member D.

G, indicates a pawl carried by the lever arm adapted to engage the teeth of the internal ratchet wheel and pulley B.

H, denotes a weighted arm secured to the shaftg, of the pawl G.

I, is a spring secured to the weighted arm H. I

J, is a flexible connection between the lever arm F, and the operating rod K, projecting through the dash-board L, the upper end of the rod being fitted with a handle K, (shown in dotted lines) for convenience of operation.

M, is a pulley, around which the flexible connection J, passes.

N, indicates a pulley for the fan N, actuated by the belt N in turn driven by the ratchet wheel and pulley B.

0, denotes a spiral spring connecting the lever F, with the frame of the automobile.

Having indicated the several parts by reference letters, the construction and operation of the device will be readily understood. To start the engine, the rod K, connected with the lever F, by a chain or cable, is manually pulled by means of the handle K, whereupon the pawl G, engaging one of the teeth of the internal ratchet wheel pulley as indicated in Fig. 1, serves to rotate the crank shaft of the engine. The crank arm being under control of the spring 0, is returned to its initial position, upon the release of the rod K, by the operator. Thus the operator may give the engine crank shaft one or more quick successive turns, if necessary to start the engine under its own power. In the event of the engine back-firing, the operating lever on its return to its initial position is released from engagement with the ratchet wheel upon the spring 1, carried by the weighted arm H. contacting with the frame or chassis P, (indicated by a line in Fig. 3) of the drawing :-it being obvious that the weighted arm when forced upward through contact of the spring I, with the frame will serve to trip the pawl G, out of engagement with the ratchet wheel ;the spring absorbing the shock it might otherwise sustain. Thus the ratchet wheel is free to turn in a counter clock-wise direction, as indicated by the arrow in Fig. 3. Upon the lever being raised through the manual operation of the rod K, the pawl will be forced into engagement with the ratchet wheel, due to the tilting action of the weighted arm H, as will be readily understood.

WVhile, as stated in the opening paragraph of this specification, my invention is especially designed for use on a Ford motor,

its use is contemplated on other types of internal combustion engines.

Having thus described my invention, what I claim is A device of the type described, including an internal-faced ratchet-wheel adapted for constant-rotation with the crank-shaft oi an engine, said ratchet-wheel having in con tinuation thereof a stub-shaft forming extension, an annular ratchet-faced, member pinned upon said shaft-forming extension, a resiliently held lever having one end sleeved upon said shaft and equipped with a pawl arranged to actuate said ratchet wheel, said pawl having a shaft bearing in said .lever and having keyed thereto a weighted or gravity arm, said arm carried by said pawl, being adapted to have a certain amount of movement independent of said lever, said weighted arm being provided with a spring adapted for engagement with the frame or chassis, whereby in event of back-fire the lever, on its return to initial position is released from control by the ratchet-wheel. thus guarding against shock as would otherwise take place.

- In testimony whereof, I sign this specification in the presence of two witnesses.

CHARLES P. SKUBLTN'.
