The teeth 28 are normally held in engagement ywith the teeth 29 by' means of springs 35, said springs being co'led around the pivot posts 36 and having their ends attached respectively to the dogs 20 and pawls 27, and it will be readily. seen that should the crank shaft be given a reverse rotation, as when a back tire occurs in the cylinder, the locking ends of the dogs will be immediately disengaged from 4the ratchet wheel, in view of the leverage exerted on the bifurcated ends of the dogs'when the outer cndsoi the pawls are caused to swing in the arc of a circle around their pivots by the slight reverse movement of the drum 21, the position of one of the locking dogs when a back re occurs being shown in dotted lines in Fig 3.

As the outer ends ci the pawls 27 move in the arc of a circle around their pivot posts,

pins 37 attached to the faces .of said pawls.

are brought into engagement with the inner face 38 of the ring 'member 30 and,` as said face extends inwardly slightly beyond the inner edges of the teeth 29, he teeth 28 will Abe entirely disengaged from the teeth 29 and held out of engagement therewith until the drum 21 is again rotated to operate the shaft 8. The drum 21`is. rotated in one direction by attaching thereto-one endoi a flexible pull strap 39, said strap member. being wrapped any suitable number of timesy around the drum, whereby, although a drum of small circumference is used, the shaft 8 will be suiiiciently rotated to impart one complete revolution to the crank shaft, and

in order to place the pull strap in convenient reach of, the operator whereby the motor may be started without necessitating the driverA leaving his seat, said pull strap is eX- tended through the dash 14 and is provided with a hand hold 40, thus enabling the driver to give an endwise pull to the, strap while occupying the seat ofthe car,

In order to rewind the pull strap 39 upon the drum 21 and position the hand hold ad- 'acent the dash 111-, a housing 41 is attached .to the frame 10 by means of a screw 112, or- 1n any convenient manner, and 1n said housing is positioned a iiat spiral spring 43, one

end of the spring being fixed'to 'the hub le of the drum 21, while the opposite end of the spring isxed in any suitable mr to the peripheral flange 45 of the housing 41 and when the strap is unwound from the drum, the tension of the spring 113 will be increased to such an extent that when the pull upon the strap is released, the spring will 'immediately rotate the drum in reverse movement and rewind' the strap thereon.

In operation, when it Vis desired to start the engine, the gripping end 17 of the rod 13 is rotated untilvsaid gripping end engages the highest parts of the inclined faces 16, this action swinging the frame 10 rearwardly and upwardly .until the pinion 7 meshes with the gear 6 of the belt wheel 5. The hand hold l0 is then grasped and 4an outward pull given thereto which will result in rotating the drum 21 until the outer ends of the pawls 27 are swung in the arc of a circle around their pivots and moved to the lli the motor does not start with the iirst i operation, the pull upon the hand hold is released, whereupon the 'spring i3 will immediately rewind the strap ready to give another rotation to the shaft 8. Should a premature explosion or back ire occur while an outward pull is being given to the strap, the locking ends of the dogs will .be immediately disengaged from the ratchet, through the action of the pawls against the opposite ends thereof, the'length of the pawls being greater than the distance between the teeth of the ring member and the ends of the dogs, when said dogs are in their normal'v engaging positions.

As soon as the gripping end 17 is returned to its initial position, thus permitting the pinion 7 to engine has, started, 4the A swing out 'of engagement with the gear 6, A

and as the gripping end and hand hold are retained adjacent the face of the dash, they will not interfere in any manner with the operation of the car.

ln view of the simplicity ci. this device;

iis

it can be verycheaply constructed and can be readily applied to various forms of motors as the bracket can be easily attached to any suitable part of the motor casing or to the bed plate thereof, the only part required to be changed about the motor con struction being -tliatot' disconnecting the ordinary belt wheel for the fanand substi tuting a belt wheel having a gear 6 thereon.

1t will likewise be seen that in view of the compactness of this device it can be readily positionedwithin the hood covering the motor without interfering with any Apart of themoton .will be I t will likewise be seen that it will require ut a minimum amount of exertion to rotztt'e the crank shaft and that seid crank shaft can be quickly rotated e number of times if occasion should require.

Having thus fully described. my invention what l. claim new and desire to secure by Letters Patent of the United States, is

l. The combination with the crunk Shaft oit e motor, of u belt wheel ixed to said motor, a geul' fixed to the belt wheel, :i pinion xswingly mounted adjaeent the belt, wheel end cooperating 'with .said gear, lneuns to Votate Suid pinion whmeby the crunk shaft rotated, n i'od connected to the pinion niolniting to seing; said pinion into or out ot engagement with Seid gen1', :1nd u 'znn cooperating with lSuid tod to move :1nd hold the rod in operative position..
