CAR-STARTER.

SPECIFICATION forming part of Letters Patent' No. 714,623, dated November 25, 1902.

` Application led August 13, 1902. Serial No. 119,574. (No model.)

arranged on a track-rail under a car-wheel and quickly operated with forceful pressure in relation to a car-wheel to start the latter and having means under control of liquidpressure.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

The accompanying drawing shows a side elevation of a portion of a car-wheel, a trackrail, and the improved starter in longitudinalA vertical section.

The numeral 1 designates the body of the device, having a forwardly-projecting extension or foot 2, tapered downwardly toward its free end for easy insertion under the lower rear portion of a wheel-rim, the bottom 3 of the body being horizontally straight and provided wiih transversely-extendin g knife-edge grips et to take into the upper surface of the head of the rail to which it is applied. Extending longitudinally through the center of the greater portion of the body 1 is a cylindrical liquid-chamber 5, opening out through the rear end of the body and closed at said end through the medium of a screw-plug 6, having a rearwardly-projecting lug or analogous device 7 for convenience in removing and. applying the same. Communicating with the forward terminal of the chamber 5 is an',upwar ily-inclinedV socket 8 of greater diameter than the said chamber and having a cylindrical pressure-head 9 movably mounted therein and formed with a convex bearing end 10. In the upper part of the rear eX- tremity of the body 1 is an upstanding screwsupport 11, which is pivotally connected to the lower end of a link 12, having its upper end also pivoted to the forward extremity of an operating-lever 13, movably attached to the upper extremity of a plunger 14, slidable through a vertical opening 15 in the rear outer portion of the said body, the said opening 15 communicating with the rear of the chamber 5.

In preparing the improved starter for use the plug 6 is removed and the chamber 5 lled with a suitable liquid, the pressure-head being pressed inwardly its full extent during such illing'operation. After the liquid has been disposed in the chamber 5 the Aplug 6 is reapplied and the starter is ready for use. In arranging the starter for engagement with a car-wheel or the like it is placed on the upper surface of the head of a track-rail, as clearly shown in the drawing, and the convex out-er end of the pressure-head 9 is brought to bear against the rim of the wheel. The plunger 14 is then depressed by bearing downwardly on the lever 13, and the compression of the liquid into chamber 5 will force the head 9 forcefully outward from the forward eXtremity of the body against the Wheel-rim and start the latter to move. The expulsion of the head 9 will be regulated by the downward pressure exerted on the lever 13, and after the wheel has moved away from engagement with the head 9 the starter may be shoved along or reset on the track-rail and the same operation repeated to insure a starting movement of the car-wheel. By elevating the plunger 14E the liquid will be allowed to recede and permit the head 9 to assume its lowered position, as shown.

It will be understood that the plunger 14 and head 9 will be supplied with suitable packing-rings or other analogous devices for insuring a tight joint between the same and the parts of the body with which they engage to prevent leakage and obtain the full bene- [it of the pressure of the liquid within the chamber 5.

The improved device will be foundeXceptionally useful for the purpose for which it has been devised, and for different applications changes in the proportions, dimensions, and minor details may be resorted to without in the least departing from the principle of the invention. i

Having thus fully described the invention, A

what is claimed as new .is-

1. A car-starter comprising a body having a longitudinallyextending liquid chamber ICO therein, a movable pressure-head arranged at an upward angle of inclination and operated by the liquid Within'the chamber; and a vertically-disposed plunger coperating with the rear portion of the chamber and adapted to force the head upwardly and outwardly when depressed.

2. A car-starter comprising a body having means for holding it in applied position on a track-rail and also provided with a longitudinally-extending horizontally-disposed liquid-'chamber and communicating with an upwardly-inclined socket, a pressure-head movably mounted in said socket, a plunger movable through the rear portion of the body and adapted to enter the said chamber, and a lever for operating said plunger.

In testimony whereof we ax our signatures in presence of two witnesses. v
