Application filed June 26, 1912. Serial No. 705,3 95.

To all whom it may concern: l

. Belt known that we, G'EoRcE K. EWING and ConnvR. F ARLEY, citizens-of the United States of America, and residents of Ewing 'ton, Gallia county, in the State of Ohio, have jointly invented a. new and useful Improvement 'in- Mechanical Starters for Auto mobile'sfbf; which the following is a specification.

This invehtionrelates to mechanical desubstitute for ground.

The present invent-ion consists in certain novel combinations of parts, hereinafter particularly describedfland clainiedi The leading object of the invention is to provide for starting the motor from 'the seat cranking the same from the of the automobile by an effective handdeverj mechanism.

' Other objects will be set forth in the general description which follows.

specification as part thereof.

Figure 1 is an elevation .of the distinctive parts of the improved -starter, showing the same at rest; Figs. 2 and 3 are like views,

36 illustrating the operation of the starter;

Fig.4 is a top View of the crank shaft, fly-. wheel and starter conneetions of the motor.

Like reference characters. refer to like parts in all the figures.

"nism are a ratchet-toothed sector and pinion, l and 2, constructed and arranged to'1ntermesh with each other as shown inFigs. 2. and 3, "but normally held outof mesh by a 40 sprin 3, as in Fig. 1. The sector 1 is car- 'ried by the lower end of a hand-lever, 4, whichin common with an abutment, 5, for

' ranged at right angles to the motor shaft 10,

Fig. 4, and permanently geared thereto by bevel gearing" 11-12, Fig. 4, which should .be in perfect mesh.

The motor shaft 10 shown in Fig. 4 is provided with cranks 1', 2', 3, 4 for. a fourcy-linder motor, and with a fly wheel,- 13, adacent to which the bevel gear-12* is keye-l .fastto the crank shaft. It will be obvious that the motor shaft may be that of any in ternal combustion motor.

The motor being still or dead and the starter at rest as in Fig. 1, the operator, grasping the handle of the hand-lever 4,

sented by the arrows a and b, Fig. 1, until the sector 1 and pinion 2 are in perfect mesh as in Figs. 2'and 3, and then turns the handlever by a quick pull as represented by the arrows. c and d, which turns the motor shaft 10 in the proper direction as represented by the arrow 6. If the motor has not started by'the end of a pull, illustrated by Fig. 3,

. endwisepressure on the hand-lever 4 is relaxed, which permits the sprin 3to disengage the sector 1, and the handever is then returned toits position of rest, Fig. 1, and again operated as before; and this is repeatv ed until the-independent rotation of the i110 tor shaft and therewith the pinion 2, represented by the arrow f, Fig. 3, has begun. Should the sector 1 and pinion 2 be in mesh when the motor starts, the beveled shape of the ratchet teeth of the sector and pinion causes them to be automatically disconnected, and prevents any jerk on the hand lever. In the starting operation the momentum of the fly wheel 13 materially assists by prolonging the movements manually begun by the starter The sectorl may be of greater or less an gular extent. if desired; other forms of spring may be substituted for the helical spring 3; and other likemodifications in details will suggest themselvesto those skilled 100 in the art.

Having thus described said impiioveiiieiit, we claim as our invention, and desire to patent under this specification: l... A mechanical starter for automobiles having, in combination, an endwise movable handle'ver carrying a ratchet-toothed sector, af-ulcrum for the same, a ratchet- ,toothed pinion constructed and arrangedJo the motor shaft, and means whereby said hand lever and sector are rendered normally retracted.

2. A mechanical starter for automobiles having, in combination, an endwise movable hand-lever carrying a ratchet-toothed sector and constructed with a longitudinal slot and superjacent shoulders, a horlzontal pivot extending through said slot, a spring abutment, movable on the same pivot, a spring compressed between said abutment and shoulders, a ratchet-toothed pinion constructed and arranged to mesh with said sector, and a shaft and gearing connecting said pinion with the motor shaft.

3. The combination of a horizontal motor shaft provided with a fly Wheel, a horizontal starter shaft at rightangles thereto,

bevel gearing connecting said shafts, a ratchettoothed pinion fast on said starter shaft,'a

ratchet-toothed sector constructed and arranged to mesh with said pinion, a longitudinally slotted. and shouldered hand-lever carrying said. sector and extending upward therefrom, an abutment opposed to the shoulders of said hand-lever, a horizontal pivot,icom1non to said hand-lever and abutment, extending through the slot of said hand-lever, and a helical retracting spring compressed between said abutmentand shoulders, substantially as hereinbefore specified. v
