Be 'it known that. L' JOHN CHARLESHEN 4Dansen,L a' citizen of the United States, re`

Si'din `atlSan-lEninoisco, in the county of 5. San trancisco and State of Caliiornia, have *invented certain .new and-useful "Improve,-

ments yiii Starters for Engines; aiiddo.

hereby declare. the following to bea full, Clear, and exact" description of the invention, suoli as lwill .enable o'thersslrilled .inthe art sam-e.. y l y M'yfinvention rela-tes to new and useful i improvements in starters for engines andl yis adapted more particularly .to be use'dtor starting theengines of motorpropelled ve-- hicles and-'my 'object is to provide suitable lgearsin connection with the shaft or-"other `parte; of thei'noto'r, through the -medium of which the shat of theinotor vmaybe rotated.

A further 'object is to `provide mea-ns lfor moving one of said gears intoor out of engagement' with the .other gear."

' A further 'bject is to .connect a segmental.

-. 1 gear withthe movable gear, whereby `when said rsegmental 'gear is moved upwardly, said gears will be rotated, and, a Lurther object is to provide a lever and .connect the same to said segmental near', said Alever beingl .in

@ther objects and, advantages will be more particur y hereinafter referred to and larlv' pointed out in the specification here- 'a-unto'annexed. l i 1n 4the'eccoiiipanfy'ing drawings which are made a .art idf-'this application, Figure 1 is a deta' side elevation of an automobile i vshew/ing. my im roved. starting device ap- 40 pliedthereto. ig. 2 is a' detail perspective view of abortion of an `automobile showing the manner 'of placing the starting lever- 'therein .Figi 3 isa detail transverse sectional view of rthe starting mechanism on an enlarged scale.

or any preferred manner;

' "lt hasbeenthe custom heretofore in starte ing engines -of automobiles to extend the these parts being constructed-in thejusual shaft of, the engine' to the forward end; of x the automobile and engage the same withv a ..3"5 crank, thus'necessitating considerable energy" 1in crankingf the engine, as well as the danger of-being struck bythe crank should. the

engine fly back and to overcome this obje,C

Ationalolefeature and at -the same time pro- 79' .I vide means whereby the engine. may be started without vleaving the vehicle, a 'lever eis extended upwardly throughv the floor 3,"

a slot- 5 being .out through, the floor and substantially at the transverse centerfof the automobile. The lever 4 is pivoted to:` a shaftl 6 ata suitable point belowI the iioor ,y

. and has a terminal '7 below its pivot, which" terminal extends laterally, forwardly land y downwardly, thus disposing said terminal to 80 one side of the longitudinal axis of the lever,

lto' 1which it is attached. The free end of the terminal I has att-achedthereto a link 8,which link coperates with a. pin 9 icarfried by a segmental gear 10, one end of the 85.

segmental gear 'being pivoted to an extension 11, which extension lis attached in any mannen t'partsof the frame 1 anddepends therefrom.' One port-ion of the segmental gear l()v is formed into a segment of a' cir- 90 cile andhas teeth 12 on its outer edge, which coperate withv teeth 13 of a pinion 14, said pinion being rotatably mounted upon a shaft 15, which'shaft is in Aturn carried by hangers 16. Also rotatably and movably mounted uponthe shaftgl. isa' gear 11 Y' inion an being adapted to-mesh with the teethy of a gear 18, which latter gear, int-his instance, 10C'4 '1s fixed to. theiiy wheel'v 19 of the engine,

erably .formed into aball`- or knob 21, which bears against the free end o'the pinion 111, so that when the arm is swun A1n one d1- rection, the'pinion and` gear wil be moved gear 17, the tension of the spring serving longitudinally of the shaft 15 and into engagement; with the teeth of the gear 18. The arm 20 is adapted to be swung in one direction through the medium of the pressure of the foot upon a foot lever 22, said foot lever having a horizontal and a vertical section, the horizontal section having a tread plate 23 thereon, while the vertical section has attached thereto one end of a rod 24, the opposite end of the rod being secured to the arm 2O adjacent its lower end and as said foot lever is pivotally mounted in brackets 25, it. will be readily seen that when the end of the horizontal portion is depressed, the arm 20 will be swung into engagement with and move the gear 17 into engagement with the gear 18. After the pressure has been released from the foot lever 22, the gear 17 is moved out or" engagement with the gear 18 by means -of a coil spring 26, which is positioned between one of the hangers 16 and the hub of the to hold the gears out of engagement with each other until such time as the foot lever is operated to connect said gears.

In order to guard against injury7 to the operator should the engine back lire, I provide means for automatically disengaging the gear 17 from the gear 18 and to this end, a cam 27 is swim@l from the shaft 15 and placed between the Aear 17 and the spring 26, said cam exten ing downwardly and forwardly so that the free end thereof will move into engagement with the gear 18 when the gear 17 is moved into engagement therewith. That face of the cam engaging the periphery of lthe gear 18, is curved to conform to the contour of the gear so that the frictional engagementof the cam with the gear 18 will cause the cam to swing upwardly when the gear 18 is rotated in the wrong direction and as the cam is placed at the inner face of the gear 17, the upward swinging movement of the cam will force the gear 17 outwardly and disengage the same from the gear 18, thus preventing the lever from kicking 'in case of premature ignition or back Atiring.

The end of the cam 27 is preferablyheld -in close proximity to the perlphery of the gear 13 by means of a coil spring 27", one end of said spring being attached to said cam and the opposite end thereof to .any suitable part lof the frame of the vehicle. As, shown, thel spring 27al will be compressed when ythe cam is elevated between the gears. When the gears have been separated, said spring will return said. cam to initial poy sition.

placing the foot thereon, which will result in moving the gear 17 and pinion 14 attached thereto, longitudinally of the shaft 15 until the spring 26 is depressed, which stops furher movement of the gear inwardly.

will result in swinging the segmental gear 10 upwardly and rotating the gears, which will impart motion to the shaft of the eugine. If the engine fails to start with one operation of the lever, pressure is released from the tread plate and the lever 4 swung forwardly, which will lower the segmental gear and parts eoperating therewith so that by'again moving the sliding gear into engagement with the gear 18, the starting operation may be repeated.

The segmental gear 10 will normally descend by gravity, but in order to cause the same to positively descend when the gears are out of mesh with each other, a spring 28 is attached to a projection 29 on the segmental gear. I

As the segmental gearlO remains stationary so far as its lateral movement is concerned, the pinion 141- is constructed of such length as to compensate for the movement of the pinion on its shaft, thus keeping the teeth of the segmental gear in engagement with the pinion at all times.

V/'hile l.' have shown and described the gear 18 as connected with the y wheel of the engine, it will be readily understood that said gear can be connected to the usual form of clutch mechanism (not shown) or direct to the shaft of the engine, or to any suitable part of the motor. It will further be seen that by placing the main lever substantially in the center of the vehicle, said lever will be suiciently removed from the other levers as to avoid confusion and it will also be seen that the engine can be readily started without the drlver leaving the seat. It will further be seen that in view of the simplicity oA the device, it can be very chea ly and at the same time strongly and duranly constructed and it will further be seen that the starting mechanism can be readily attached to any make o vehiclehavinfr an internal combustion engine for propeiling the same.
