CAR-STARTER.

SPECIFICATION forming part of Letters Patent No. 261,492, dated July 18, 1882. Application filed June 5, 1882. (No model.) Patented in Denmark January 2l, E82.

To all whom it may concern:

Be it known that I, HANs CHRISTIAN EMIL S'IILHOFF, a subject ot' His Majesty the King of Denmark, residing at the city of Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in Car-Starters and I do declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part ot' this specification, and in which- Figure l is a side view of my improved carstarter as applied to a car-wheel. Fig. 2 is a transverse section ot' the same, with so much of the wheel as is necessary to illustrate the operation of the device. Fig. 3 is an end or edge view of the device in its modified form for its application to a vehicle-wheel. Fig; 4 is a side view of the same. Fig. 5 is a sectional detail View, through line x x in Fig. 3, of the clutch or lock-pawl which interlocks with the rim or face of the wheel; and Fig. 6 is a detail top view ofthe draft beam or bar which is attached to and Qperates my device.

Similar letters of reference indicate corresponding parts in all the tigures.

My invention has relation to that class of car-starters in which the power of the team is temporarily applied to give direct impulse upon the wheel, soas to start the latter rolling, and then transfer the draft direct to the front axle, as usual; and it consists in' the improved construction of the same, as hereinafter more fully describedand particularly pointed out in the claim.

I shall first describe the constrcton of my device as applied to a car-wheel, and afterward its construction as applied to a vehicle-wheel or spoke-wheel, the construction and combination of the co-operating elements being substantially the same in both cases, and only modited to admit ot' their application to wheels ot' different character.

Referring to Figs. l and 2 in the drawings, the letter A represents a cast-iron car-wheel of any approved construction.

t' and t' are two slotted arms, the parallel lower parts, t" and i', of which are bolted together on opposite sides of the axle-box a, while their diverging upper slotted parts, which are connected by a brace-bar, I, form bearings for a curved bar, h, the curvature of which is concentric with the-wheel.

One et' the pendants or arms d of the yoke.

d is -slotted to receive the clutch or lock-pawl c, the inner end of which engages the serrated rim or flange s of the wheel.

A stout spring,f, connects the shank c of the lock-pawl c with the free end ot' thedraftbar b, the lock-pawl c being pivoted within its slot or box in the yokeafl d', so as to permit its inner end to engage the rim s ot the wheel A, as aforesaid, when it (the pawl) is actuated by its spring f.

This will be the relative position of the parts as indicated in Figs. 1 and 2 of the drawings. When the draft is applied to chain b it operates to tilt the yoke d in the direction ot' the line of draft, thereby imparting, through the clutch or lock-pawl c c', a direct impulse upon the rim of the wheel, which is kept up unt-il the arm d has been tilted enough to strike the arm or box t' of the arch h which is nearest to the line of draft. When the parts h, d, and d are in this position a triangular release-block, g, which is affixed upon the draft-bar b, will strike the projecting shank c of the clutch or lock-pawl c, and thus disengage it from the rim s of the wheel, in which disengaged or released position it will remain during the application of the draft. When the car stops yoke d may be brought back into its normal vertical position by means of a lever attached to it, or by any other suitable Ineans.`

In the application of my device toa wagon or spoke wheel the pivoted clutch is of the construction shown in Fig. 5 ot' the drawings, from which it will be seen that it is in the nature of an eccentric pivoted in the upper IOC slotted part of the yoke d', the shoulder c2 of l which, actuated by the spring f, (which in this case is in the nature of a leafspring or barspring secured upon the side of arm d of the yoke d,) bears against the rim of the wheel. In tilting arm d by its pivoted draft-bar b the clutch or eccentric c is released from binding against the rim of the wheel by the lip ca striking the nut b2, by which the bent inner end of the draft-bar is bolted to the arm or upright d, the arch h being in this case dispensed with, and arm d being pivoted either upon the hub or the axle of the Wheel.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- In a car-starter of the described class, the combination, with one or more of the wheels In testimony whereof I have hereto affixed 3o my signature in presence ot' two witnesses.

HANS CHRISTIAN EMIL STILHOFF.
