Specification of Letters Patent. pat-elltid AK)!- li 1911 Application filed February .23, 1910. Serial No. 545,356.

Be it known that we, CHARLES H. SMITH and ARTHUR L. GODDARD, citizens of. the residing at Rockford, in the county of \Vinnebago and State of Illinois,

following is a specification.

The object ofthis invention is to produce a simple and convenient device for starting the internal-combustionengine of an automobile or motor boat. Another object is toprovide an engine starting apparatus which may be readily applied to existing motor cars.

In the accompanying drawings, Figure 1 is a sideelevation illustrating the applica- 'tion to an automobile-of an engine-starting starting the engine, by

'gether by means of apparatus embodying the features of our in vention. Fig. 2 is a top plan view of the parts shown in 1., Fig. 3. is a vertical sectional View taken in t-he plane of dotted line 3 3' of Fig. 2, Fig. t is an" enlarged view' of some of the parts shown in Fig. 3.

Fig. 5. isv a sectional detail illustrating a.

lock for the operating lever. section on line 6 GofFig. 4. section on 1ine717 of -Fig. 4. p

In the illustrative embodiment herein shown of our invention, A" isoiue ofthe side sills of the chassis of a inotorv ear, B ,is the Fig. 6 is a Fig. 7v is a dash, C is the engine, Disthe engine shaft, and is the radiator;

The shaft D is arranged to be" rotated, for the purpose of pawl and ratchet mechanism, The rate et wheel '1' maybe made in sections, as herein shown, for convenience in. applying the invention to existing cars, We have shown the sections of the ratchet wheel 1 as secured tokeys 2 and the wheel as'being secured to the engine shaft D by a key 3. The ratchet wheel is'located forward of the engine, in the engine and the radiator.

The ratchet wheel 1. is arranged to be engaged by the pawl within a flanged pulley or drum 5 and is pivotally supported upon a pin 6 or other suitable member secured in the sides of the pulley; A spring? of any suitable form 8 is a, stop to means comprisin a the narrow space between 4 which is mountedlimit' the movement of the ratchet wheel.-

To facilitate the application of the invention to existing structures, the pulley 5 is made in two sections secured togetherby bolts or other suitable fast-enings 9 passing through flanges l0 onthe ulley sections. The pulley is loosely mounted on the engine the pawl away Irom and the fiangesof the pulley.

chain ,11 to rotate the pulley 5 consists of a bell-crank lever 15 pivotally connected to a bracket .16 on the sill A, One arm-of the bell-crank is connected with the chain by means of a link 17. The other arm of the bell-erank is connected through the medium of. a link 18 with the lower end of a lever 19,

the upper end of said lever being pivoted at 20 upon ,a base plate 21 attached, inthis instance, to the side of the car just rearwardly of the dash. An operating handlever 22 is pivoted at base plate 21 and is connected by means of a link 23 withthe lever 19 at a point be tween. the ends of the latter.

Suitable means may be provided for preventing the lever 22 from being jarred or otherwise accidentally movedout of its n0rmal position. WVe have herein shown a spring-pressed plunger 24: mounted on the base plate 21 and adapted to'enter a socket in the adjacent face of the hand-lever.

ratchet wheel after the engine has been started, and for permittingthe spring 7 to engage the pawliwith the ratchet wheel, -we provide upon the inner end of the link 17 aprojection 25 adapted to engage the tail 26 of the pawl and rock the awl upon its is to say, toward the shaft. An opening, 27

shaft, sothat the latter may rotate withoutits lower end to the In order to withdraw the pawl .4 from the pivot when the link is moved inwardly, that r 105 The means herein shown. for moving the v isforroed in the peripheral wall of the iml modifications will occur to persons skilled from the ratchet wheel.

ley 5, through which opening the inner end 1 of the link extends. The projection 28 on the an lar inner end of the link 17 assists to gui e said angular end into the'opening 27. As shown in Fig. i, the periphery of the pulley lies between the chain and the projection 28, said projection assisting to prevent sagging of the chain at this point or downward withdrawal of the projection 25 from the tail26 of the pawl.

When it is desired to start the engine, the operator grasps the hand-lever 22 and swings it rearwardly, thereby causing the bell-crank 15 to be rocked and drawing the link 17 'outwardly. Themovement of the link causes a movement of the chain 11, and the'latter being connected to the pulley 5, causes a partial rotation of said pulley. As the link 17 moves outwardly and the pulley 5 commences to rotate, the projection 25 and the tail 26 of the pawl move apart, thereby permitting the spring 7 to throw the pawl into engagement with the' ratchet. wheel. Continuing movement of the link, chain, and pulley causes rotation of the engine shaft. The extent of the movement thus imparted to the engine shaft may be suiiicient to start the engine; if it is not, the operator causesfurther rotation of the engine shaft by swinging the lever 22 back and forth.- When the hand-lever is thrown into the position shown in Fig. 1, the projection 25 is moved into engagement with the tail 26 of the pawl 4, thereby withdrawing said pawl It will be, seen that the apparatus herein described is simple, and is arranged for convenient operation. from the drivers seat. The portions adjacent the engine shaft are small and compactly arranged, so that the apparatus can be applied to cars now in use by connection with the shaft at the only point generally available, namely, in the narrow space between the engine and the radiator.

The invention is not limited to the precise. details illustrated and described, for various in the art. I

We claim asour invention:

1.

V 2. In an engine starter, in combination, a 1

pulley loosely mounted on the shaft and inclosing the ratchet wheel; a pawl pivotally supported within said pulley and adapted to engage said ratchet wheel; means tending to move the pawl into engagement with the ratchet wheel; an idler; an endless connection extending about said pulley and said idler, said connection being attached to the pulley; means for pulling said connection to turn the pulley; and a member moving with said connection and movable into and out of the pulley through an opening therein, said'member being adapted to engage said pawl to disengage it from the ratchet wheel.
