EXPLOSIVE-EN-GINE STARTER.

T all whom it may concern:

Be itknown that I, JAME R. Bra ns, a.

citizen of the. United States, residing at Canton, 1n the county of Stark and State of Ohio, have invented a new and useful EX- plosive-Engine Starter, of which the following is a specification.

My invention relates to explosive engine starters and has more especial reference to 1G a device, adapted to replace the ordinary crank used for starting automobile engines.

This device is adapted for more conveniently turning over the engine shaft, the

mechanism being so arranged that the op erator may have greater advantage in prop-' engine with a minimum exertion, the device being easily and conveniently operated and capable of being applied to' or removed from the engine practically as a unit without the necessity of altering the construction of said engine.

Another object'is to provide a device which will be out of engagement with the engine shaft and idle during the time the engine is running and which is only thrown into engagement with the engine shaft when it is desired to start the engine.

\Vith these objects in view the invention consists in the novel construction and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appendoil claims, it being understood that various.

changes in the form, proportions, size and minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the inven- Referring to the accompanying drawings: Figure 1 shows a top plan view of a pprtion of an automobile chass s and engine showing my explosive engine starter applied thereto. Fig. is an enlarged longitudinal sectional view taken through my explosive engine starter. Fig. 3 is a section on line 3 -'3, Fig. 1. fFig. 1 is a top plan View of a portion of my device, parts being Specification of Letters-Patent.

broken away for the purposeof illustration.

Fig.'5 is a section taken on; line 55, Fig. 1.

Fig. 6 is a side elevation of a portion of my device, parts being broken. away for the purpose of illustration. Fig. 7 is a vertical sectional View through the compound pulley fused in my device. Fig. 8 is a fragmentary elevatlon of a portion of the operating pedal, showing the outer side .of said pedal.

Similar numerals of refereifce indicate corresponding parts throughout the several figures of the drawings.

Referring more especially to the construction illustrated in the accompanying drawings, the numeral 1 indicates a portion of the chassis of an automobile and the numeral 2 the engine, which may be of any usual type of internal combustion engines. The numeral 3 indicates the engine shaft to which shaft is secured by means of the pin a the usual cylindrical member 5, which is provided with the clutch member 6 such is ordinarily provided upon the engine shaft for the purpose of cranking the engine. Secured to the cylindrical member 5 by means of screws 7 or their equivalents is a clutch member 8 provided with a series of teeth 9. The usual crank 10 such as is ordinarily used for cranking an automobile engine is suitably journaled in a bearing 11 The usual extremity. of the crank 10 by means of a Loosely mounted upon the member 12 is a sliding sleeve 14 which is provided with a spoke 15, which spoke supportsa segment 16 provided with a peripheralgroove 17 said segment adapted to rotate around the out side of the housing 18 as'best shown in Fig. 5 ofthe drawing. To the inner extremity of the sleeve 14 is connected a clutch member 19 by means of screws 20 or their equivalent, said clutch member being adapted to engage the clutch member 8 as hereinafter described. A coil spring 21 is located around the sleeve 14, one endof said spring being bent around the spoke 15 shown at 22, the other end of the spring resting in a notch 23 in the housing 18, the spring thus the memberf 8.

after described and'pointed out. Connected at one end. ofthe segment 16 by means of a screw 26 is a chain 27 which is located around the groove in the 'segmentand t%eln compound" pulley is composed of a large passes over the compound pulley 28.

sheave 29, and a small sheave 30, which are preferably made integral, the chain 27 passing first around the large sheave and then up and. aroundthe smaller sheave as best shown in Figs. 1 and 3 of the drawings. The chain is then continued back along the frame of the machine over aguiding pulleyv 31 and around the segment 32 being attached to the rear extremity of said segment.

The segment 32 is pivoted at..33 upon-a suitable axle which is connected to the side wall 34 of the automobile as shown. A. foot lever 35 is provided with a sleeve 36 which has a bearing upon the axle 33,. said foot lever being provided with a downwardly depending arm 37 which is adapted to be contacted with a set screw 38 located through a lug 39 in the segment 32., 'A bracket 40 extends downwardly from the axle 33 and is supported upon the channel frame of the chassis 1. The foot lever 35 is normally held in the position shown in Fig. 3 by means of. a spring 41 mounted upon the dash board 42 of the automobile, the shoulder 43 of the spring engaging the lug 44 upon the-end o I the foot pedal.

The operation of the device. is as follows: The parts are normally held in the position shown in Figs-'1 and 3, the foot pedal 35 being held forward by means of the'spring 41. Thesegment 16 is thus held in the position shown in Fig. 1 and in dotted lines in Fig; 5, as the chain is thus drawn back by means of the segment 32. In this position-the spoke 15 will be engaged by the inclined face 25 of the arm 24, thus holding the clutch member 8-.out'of engagement with the clutch member19. Whengit is desired to' start ;the engine the spring 41 is pushed back with the foot releasingv the lever 35 and allowing it to assume'ajvertical position. The pull being thus removed from the chain 27 allowing the spring 21 to throw the 1 segment 16 into the position shown in Figs. 5, 6 and 7 the spoke 15 engaging with the inclined face of the arm 24*; holding the clutchmembers 8 and 19 out of engagement with each other. The foot pedal 35 is then thrown forward again into the position shown in Figs. 1 and 3, the segment 16 being revolved, bringing the spoke 15 out. of engagement with the inclined face of the arm :34 and allowing the clutch member 8 to engagethe clutch member 19 thus rotatthe engine shaft'3. As the segment 13 xcompletes itsfmovement the spoke 15'will engage the inclinedface uponthe arm 24, thus throwingtheclutch members again out of-engagement as the engine is started. It

Jwill thus be seen that at all times while the device not in operation, either while the engine is running or dead the clutch memher .8 will'be held out of engagement from the clutch member 19 and said clutch members are only thrown into engagement during the operation of starting the engine.

This crank of course, is not necessary except when the driver of the car wants to start the engine 'fromthe outside when he can use the crank in the usual manner. The clutch member 12 upon the crank is nor-' mally held out of engagement with Ithe clutch member 9 by the usual spring 46.-

Although the drawings and above specification disclose'the best mode inwhich I have contemplated embodying my invention I desire to be not limited to the details of such disclosure, for, in the further practical application of my invention, many changes in v form and construction may be made, as circumstances require or experience suggests,

without departing from the spirit of the invention, within the scope of claims.
