STARTING DEVICE FOR EXPLOSIVE-ENGINES.

Specification of Letters Patent.

. Patented Aug.'1s, 1912.

Application filed September 10, 1909. Serial No. 517,028..

To all-whom it may concern. 7 Be itknown that I, WINFIELD S. REGUR, a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Starting Device for Explosive-Engines, of which the. following is a specification.

The obj ect' of my invention is to provide a device of simple, durable, and inexpensive construction, especially adapted for use on automobiles having explosive engines whereby the operator may, While occupying a seat in the automobile, readily and easily turn the shaft of the engine one or more revolutions as required in starting the engine,

My invention consists in the construction, arrangement, and combination of the various parts ofthe device whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows a side elevation of a part of an automobile with my improved starting device applied thereto. Fig. 2 shows a plan view of a part of an automobile chassis with an engine contained thereon, and with a portion of my attachment applied to the engine shaft. Fig. 3 shows an enlarged, detail, sectional view on the. line 33 of Fig. 1. Fig. 4 shows an enlarged, sectional view on the line H of Fig. 3. Fig. 5 shows an enlarged, detail, sectional view on the line 55 of Fig. 3, and Fig. 6 shows a detail, end view illustrating the sector and the fulcrum used forthe operating lever.

. Referring to the accompanying drawings, 1 have used the reference numeral '10 to indicate those portions of the automobile shown. 11 indicates an explosive engine mounted in the automobile frame and having a main driving shaft 12. These parts are all of the ordinary construction and of themselves form no part of my present invention, but-are illustrated for the purpose of showing the manner in which my attachment is applied to an explosive engine in an automobile. I Keyed to one end of the driving'shaft 12 is a sleeve 13 having a ratchet wheel 14 Rotatably mounted upon this sleeve 13 is'a disk 15 which forms one side designed to inclose said ratchet of a casi pg wheel. e mating part of the casing is indicated by the numeral 16 and it is connected with the'disk 15 by the screws 17.

Formed on the outer portion of the casing member 16 is a pinion 18, said pinion and easing being formed to-rotate on the shaft 12. Said casing 16 is provided on its in terior with a spring actuated pawl 19 normally in engagement with the ratchet wheel 14:. By means of this arrangement of parts, it is obvious that when the pinion 18 is given an alternating, rotary motion, the said ratchet wheel 151 and the shaft 12 to which it is keyed, will be rotated intermittently in one direction only, and inasmuch as theengine shaft 12 rotates in one. direction only, I- have arranged the ratchet device in such a manner that it will turn the engine shaft in the directiomin which the engine moves when in operation.

For operating the pinion 18, I have provided the following mechanism: Mounted upon the side of the automobile body isa sleeve 20 having formed on its upper por-' tion a sector 21. This sleeve is provided with a. shaft 22 on which is fulcrumed a segmentalrack 23, which rack isin mesh with the pinion 18. These parts are so arranged that when the lever 24 is moved to its rearward limit, it will be thrown to position out of contact with the pinion 18 so that said pinion may freely rotate with its shaft without having the ratchet device connected therewith in' continuous operation, such as would be the case if the said pinion 18 were held against rotation by the rack.

Fixed. to the rack 23 is a hand-lever 24. ex tended upwardly and provided with a spring-actuated pawl device 25, the latter being designed to engage the sector 21. The

handle of the lever 24 is projected to position Where it will be conveniently accessible. to a person occupying the operators seat of the automobile. I

The reference numeral 26-indicates a protecting shield fixed to the automobile body to inclose the segmental rack and pinion.

In practical use and assuming that it is desired to start the explosive engine, the operator first grasps the springfactuated ratchet device 25 to hold, it out of engagement with the sector 21. He then moves the lever 24 forwardly and rearwardly thus imparting an alternating, rotary motion to the pinion 18. This will, in turn, impart anintermittent, rotary motion in one direction that the operator may impartto the lever 24:, any length of stroke which most convenient for him, and he may also apply to the upper end of the lever a comparatively light amount of power. This power is greatly increased oniaccount of the length of the handle end of the lever as compared with the length of the segmental rack, and,-

hence it may require a comparatively large number of reeiprocations of the operating lever to turn the power shaft a complete revolution. However, an advantage is gainedin the fact that by this arrangement an engine having a comparatively high amount of compression and requiring considerable power to turn, may be started with a comparatively light amount of power applied to the handle end. of the lever I claim as my invention:

1. A starting device for explosive engines,

comprising a power shaft, a sleeve keyed to the power shaft, a ratchet wheel formed on Copies of this patent may be obtained for five cents each, by addressing the the outer end of said sleeve, a disk rotatably mounted on the sleeve, a casing member screwed to the disk, a pinion formed on the casing member and rotatably mounted on the power. shaft, a spring-actuated pawl carried by the casing to engage said ratchet wheel, a segmental rack fulcrumed above said pinion and in mesh with it, and a lever fixed to the segmental rack.

2. A starting device for explosive engines, comprising a power shaft, the powershaft, a ratchet wheel formed on the outer end of said sleeve, a disk rotatably mounted on the sleeve, a casing member detachably connected to the disk, a pinion formed on the casing member and rotatably mounted on the power shaft, a-spring actuated pawl carried by the. casing to engage said ratchet Wheel, a rack in mesh with said pinion, and a lever for operating said rack.
