MEANS FOR STARTING INTERNAL-COMBUSTION ENGINES.
Specification of Letters Patent.
Patented July 24, 1914.
Application filed October 22, 1912. Serial No. 727,128.
To all whom it may concern Be it known that we, WILLIAM F. GROLL and CHARLES P. GRoLL, citizens of the United States, residing at Waldo, in the county of Marion and State of Ohio, have invented a certain new and useful Improvement in Means for Starting Internal-Combustion Engines, of which the following is a specification.
This invention relates more particularly to devices for cranking an automobile while the driver is seated in the seat.
The object of the invention is to provide simplified and improved means of the kind stated having among its advantages adaptability to difierent sizes of automobile.
The invention is embodied in the example herein shown and described,'the features of novelty being pointed out in the claims.
In the accompanying drawings-Figure 1,
is a view in elevation of an automobile equipped with the invention. Fig. 2 is a side elevation with parts in section. Fig. 3 isa top plan view with parts omitted to show details of the invention. Fig. 4 is a front view on a larger scale of the cranking wheel. Fig. 5 is an edge elevation of the same. Fig. 6 is a detail view of the drum member.
In the views 10 designates the forward end of the crank shaft of an ordinary automobile. Journaled in a suitable cross member 11 is the shaft 12 of the cranking or starting device. Fixed on the outer end of the shaft 12 is a ratchet wheel 13 and journaled to turn on the shaft 12 is a drum member or spider including four socketed arms 14 carrying spring actuated pawls 15 adapted to engage the ratchet wheel 13. The sockets of the arms 14 receive the shanks 16 of grooved angular heads 16, said heads being held in the positions to which they can be adjusted by set screws 17 The heads 16 will, in practice be adjusted to form approximately a square pulley or drum. Attached to the said pulley or drum is a strap 18 that passes rearward around a pulley 19 to a member carrying a pulley 20, the pulley 20 being operable by another strap or cord 21 attached to the automobile and passed around the pulley 20 and the pulleys 22 and 23 and thence through the dash 25 where it is provided with a handle or knob 26 within easy reach of the automobile driver.
The spider or drum is provided with a small pulley 27 fixed to it at its hub and attached to said pulley is a cord 28 attached to and operated by one arm of a spring 29 the other arm of which is pivoted vertically in a socket 30 to permit the spring to swing easily in a horizontal plane. The function of this spring and cord is to rewind the strap 18 after the latter has been pulled in a cranking or starting operation.
31 is a lever fulcrumed at 32 and engaging a grooved collar 33 attached to the shaft 12. The free end of the lever 31 has attached to it a cord 34 that is extended rearward and under a pulley 35 after which it is attached to a sliding finger piece 36 arranged on the front of the drivers seat and within easy reach of the driver.
38 is a spring operating on the lever 31 to hold the shaft 12 disengaged or unclutched from the crank shaft.
39 is a rod extending rearward to the carbureter valve, said rod has a head 40 and between this head and the cross member 11 is a coil spring 41. The head 40 is arranged in position to be operated by the lever 31 when the latter is drawn rearward to clutch the shaft 12 with the crank shaft. This operation of the rod 39 tickles or moves the float so as to insure the opening of the gasolene supply valve and an abundant priming supply of vapor for starting the engine. The shaft 12 is shown as provided with a pin 42 that engages clutch teeth 43 on the end of the crank shaft but any form of clutching devices can be employed. The large square drum member or spider is normally mounted with reference to the crank shaft so that the pull of the strap 18 is at one of the corners when the greater com pression of the piston charge is taking place.
What we claim is- 1. A driving device adapted for use in cranking means for automobiles consisting of a rotary spider wheel having radial arms provided with a plurality of angular rim pieces 16 forming a cornered driving member polygonal in side view, a pawl on said driving member and an actuating strap connected with said driving member and winding on the rim formed by said angular pieces 16, and means for rewinding the strap after it has been operated for turning the driving member, substantially as described.
2. A driving device adapted for use in cranking means for automobiles consisting of a rotary spider wheel having radial arms provided With a plurality 'of radially adjustated for turning the driving member, subable angular rim pieces 16 forming a corstantially as described, nered driving member polygonal 1n side WILLIAM F. GROLL.
