ENGINE-STARTER.

Specification of Letters Patent. Application filed October 17, 1908. Serial No. 458,211.

Patented Sept. 21, 1909.

To all whom it ime concern:

Be it known that I, URBAN Mormon SEY- LER, residing at Nashville, in the county of Washington and State of Illinois, have invented certain new and useful Improvements in Engine-Starters, of which the following is a specification. My invention, which relates to that class of engine starters, more particularly designed for use in connection with explosive en ines of the gas and gasolene type, embo ies a easing into which the engine shaft Within the casing and fixed to the shaft to turn therewith is a ratchet disk that cooperates with a pawl which is mounted on a pawl carrying drum. The drum is turned in one direction by a cable, under control of the operator and is moved in an opposite direction to wind up the cable by a coil spring. A tension disk cooperates with the pawl to cause it to automatically engage and disengage the ratchet disk.

The primary object of my invention is to provide an engine starting device that can be manipulated from the seat of the automobile, when usedon such, and which will be constructed of few parts, simply arranged and eifectual in their operation, so that should the engine kick back or reverse its direction of rotation in starting, as often occurs, the pawl will be automatically released from the ratchet and hence the danger to the operator will be eliminated.

With other objects in view than have been specifically stated herein and which will be readily apparent to those skilled in the art to which the starter also includes those novel details of construction, combination and arrangement of parts, all of which will be first described in detail, and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Figure 1, is a perspectiye view illustrating my invention in use. Fig. 2, is a horizontal central cross section thereof. Fig. 3, is a vertical section on the line 3-3 of Fig. 2, showing the position of the parts when starting the engine. Fig. ,4, is a similar view showin the position of the parts when a back re of the engine occurs. Fig. 5, is a detail perspective view of the pawl carrying drum. iii 6, is a similar view of the Fig. 7, is a detail view of the tension rope or chaln invention appertains, myv

wheel and its brake or retarding mechanism.

Referring now to the accompanying drawings in which like letters and numerals indicate like parts in all of the figures, l designates the casing which incloses the moving parts of my invention. The casing 1 is provided with a hub 1 to form a bearing for the engine shaft 50 that projects through the casing and through a bearing 2 in the cap 2, the cap 2 being secured to t e body 1 of the casing in any approved manner, and the easing 1 may be secured to a fixed support by bolts or other means passing through the lugs 1 of the casing. The cap or cover 2 may be bolted to the body 1 by bolts 3, if desired.

Within the casin is a pawl carrying drum 4 which is provide witha peripheral groove 4; toireceive the cable, rope or chain 6, that passes through an aperture in the casing and connects with a suitable actuating lever 20, mounted in any suitable position to be grasped by the operator in starting the en-. g-ine. lhe pawl carrying drum 4: is apertured at, 4? to receive the bearing 1 of the casing 1 and is also provided with an annular projecting flange ik in which a coil spring 5 is located, the spring 5 being secured at one end 5 to the casing l and at the other end 5' to the flange 4 of the drum 1. On the face of the drum 4 opposite the flange 1 is a pawl 8 that is pivoted to a stud 9 carried by the drum 4-, the stud 9 passing throu h the elongated aperture d in the pawl 8 or a purpose which will hereinafter be more fully awl 8 with the stud 9 normally at one end of the slot 8, a leaf spring 8 is provided, the sprin 8 being secured as at 8 to the pawl 8. The pawl 8. is provided with a tooth portion 8 to engage a ratchet disk 7 which is keyed, or otherwise fixed to the shaft 50 to turn therewith.

10 designates a pin carried by the pawl 8 to project into a slot 11 in the tension disk 11, the disk 11 being apertured to receive the bearing hub 2 of the/cap 2, and is retained by a washer 12 that is bolted or screwed to the hub 2 to hold the tension disk on the cap 2 when the cap is removed understood. In order to maintain the fromthe casing. lln a like manner the drum band 14 being fixedl securedat one end 14,

Fig. 3. Since the rotation of the disk 11 is resisted by the brake band 14, it will lag to'the one 1, an at its other end is secured to a bolt 15 that pro ects through the casing, which receives a coil s ring 16 and adjusting and jam nu-ts 171 as cleagy loosenin or tighteningu the nuts 17- 'l7' shown in 'Fig. 7, of the drawings;

theban 14 may be ma e' to grip-the tension disk 11 to a greater orless extent, as

conditions may require.

In the practical application of my invention to automobiles and the like, the operating lever may be placed adjacent to the seat ofthe operator and as the operator moves the lever to pull on the cable 6, the drum 4 will be rotated in a clockwise direction, see

and hence thepin 10, which operates'in the slot 11", will 'be'forced" toward the center of the disk and thus bring the pawl 8 into active enga ement-wi-th the ratchet 7, caus-' ing the rate et 7 to turn with the drum a in the direction of the arrow. As soon as the operator releases the cable 6, the spring 5 will rotate the drum 4 in an opposite direc-.

tion, and owing to the lag of the tension disk 11, the pin 10 will move to the other end of the slot lland thus force the pawl 8 out of engagement with the ratchet 7 Should a back fire of the engine occur when the operator is attempting to start the same, the provision of the elongated slot 8 and the pin and slot connection 10* will serve to permit the pawl 8 to release itself from engagement with the ratchet 7, should the ratchet 7 commence to turn the drum 4' backwardly, as would be the case should 'a back fire occur. The proper tension may be applied to the disk 11 to cause it to lag the required amount by means of the ban 14 and the tension spring 16.

From the foregoing description, taken in connection with the accompanying drawings,

it is thought the complete construction, op-- eration and many advantages of my invention will be readily understood by those skilled in the art to which the engine shaft to turn therewith, a drum, a pawl carried thereby to engage said ratchet invention 'appertalns.
