Be it known that I, WILL'IAM FLOYD, a citizen ..0f the United States, residing at Mas,-

' tic, Long Island, State of. New York, have I ca .the driver of the motor-car, mountin is enabled to'rotate the: crankinvented eertain new and useful Improvements in'Starters for Motor-Car Engines, of

which the following is a full, true, and concise specification. This invention, a starter for'motor-car and similar engines, aims to provide a. mechanism of simple and reliab e nature, whereby without "dis shaft or y-wheel ofthe engine and thereby produce an initial compression of fuel re- (lilllll'ed for setting the engine in motion, and t e invention consists in the construction,

operation and combination of-theseveral parts hereinafter described whereby these; and other desirable results are attainedand whereby said mechanism is adaptable to dif- 1 a familiar arrangement.

Referring to the two sheets of drawings forming a part hereof, Figure 1 shows in elevation astarting apparatus embodying my invention and a plied to the fly-wheel of an ordinary type of motor-car; Fig.2 isan enlarged sectional view of a portion of the apparatus with parts in elevation and showingthe'buckle in 1011 itudinal section on line IIII of Fig. 3; Fig. 3 is. a plan detail of the buckle showing the relation of adjacent parts, F' .4 is a sectional view of the girdle on line I$IV of Fig.2; and Figs. 5 and 6 are alternate details. a

In'the type of car with which the invention is illustrated the engine crank-shaft 1 is dis osed between and parallel withthe sidegir ers2 of the car frame and also between the side-bars 3' of interior engine frame. The fly-wheel. 4 is located just'beneath the flooring 5 which is under the oper'ators feet in the relation indicated b Fig. 1,this'being he startin mechanism comprises a flexible band 6 of eather or similar material constituting a dle em- One 'end 0 the strap is connected to the cross-ba'rilpf a buckle 8,

with the cable 10 b a flat. chain 12 which works freely throug the buckle and u on the roller, and the arts are so arranged .t at a pull on the handle will tighten the strap upon thewheel if the latter is not in motion,

and a continued pull will move the strap or girdle in a circumferential direction, thereby rotating the wheel forwardly or in the direc'.

tion indicated by'thearrow A restoring mechanism, which includes a spring roller 13 and a flat wire 14 thereon, is connected to the girdle or preferably tothe tail of the buckle .as shown, for roviding a sufficient yielding resistance to t e forward pull toproduce theinitial gri ping action and also'for returnin the hue e and girdle to original or norma position. As a matter of convenience the return wire is provided with a snap-hook 19 by which it is detachably connected to an eye in the buckle. A fiat'band of sprin steel 15 is associated with the leather; girdle, being preferably securedto the outer side thereof as shown in Figs. 2 and 4, for the urpose of facilitating the opening of the gir e when the actuating mec anism is released, and the said s ring band also serves tostrengthen the ird e and hold it out of contact with the w eel while the latter is revolving. The chain 12 is provided with an adjustable stop shown at 16 which limits its movement through the buckle and holds 'lt te e y-wheel may be forwardly rotated by pulling the. handle in obvious manner so that c'ompression and combustion take place with-- in the engine and the wheel takes up its own ati'ng' mechanism automaticallyloosens the grip and allows the girdle to expand under sure such automatic release of the girdle, an

abutment is provided against which thenose of thebuckle may strike to prevent its further travel with the-wheel. Such an abut- "mentis shown herein as a spring buffer: 17 the construction of which will be apparent from the drawing. Alikeabutment or buffer '18 'is also provided on the opposite side of-the fly-wheel for the pur ose of limiting themovement of the hue aim the op osi-te dinormal action of the spring roller 13 or to a rotation, whereupon the relative forward .niotion of the wheel with respect to the actuinc the engine. In the case of a backfire, the hand rip is jerked from the operator's grasp (whic may obviously take place without risk of injury to him) and the tension in the there y prevent damage to the mechanism.

The ends of the buckle are preferably turned somewhat outwardly in order to make reliable engagement with their respective buffers.

The fixed parts of the starting mechanism are attached to the side-bars of the frame 2 and 3 above mentioned and are located in the plane of the fly-wheel, but in other types of cars these parts may be secured to such other fixed members as may be adjacent to the wheel and may be attached, if desired, to the car-body. As shown herein, the sheave 11 is journaled in a standard 20 that rests upon a uide-plate 21, both of which are clam ed y a bolt tothe flanges of the frame.- he guide-plate 21 is adjustable toward and from the fly-wheel and forms a shelf support for the spring buffer 17 above described and at its inner end terminates in forked members 22 which embrace the peripheral edge of the fiy-wheel to confine the girdle thereto. -As shown in Fig. 6 the forked members 22 are relatively adjustable toward and from each other, in order to accommodate different thicknesses of flywheels. The spring buffer 18 is supported on a similar. guide-plate shelf 23 adjustably' clamped tothe frame on the opposite side of the wheel. The roller of the spring return 1 mechanism is conveniently mounted on the under side of the frame bars as indicated in Fig. 1 where it will exert a more or less constant pressure upon the buckle or irdle.

' The roller itself may be of any desire construction. In the modification shown in prising a buckle, a contractible girdle em racing the part to be revolved and having oneend connected with said buckle, in combination'with a chain connected to the other end of said girdle and passed through the v buckle and constituting means for contracting and moving said girdle in a cir-- cumferential direction.

2. In a starter for motor-car en mes, a

buckle, a fiexible'girdle embracin t e part to be revolved and having one en attached to said buckle and the other end passed therethrough and constituting an actuating connection for contracting and forwardlg moving said girdle, in combination wi means for returning said girdle in a reverse direction.

3. Ina starterfor motor-car engines, a fly-wheel gripping device including a buckle with an out-turned end adapted to cooperate with an abutment for arresting themovement of said gripping device.

4. In a starter for motor-car engines a fly-Wheel gripping device including a girdle and a buckle in combination with a sprin return for said device connected to' the en of said buckle.

.- In testimony whereof, I have signed my name to the specification in the presence of two subscribing witnesses.
