CAR-COUPLING.

SZPEGIFIGATION forming part of Letters Patent No. 461,635, dated October 20, 1891.

Application filed April 24, 1891. Serial No. 390,316. (No model.)

To all whom it may concern:

De it known that I, GEORGE A. KENNEDY, a c1t1 zen of the United States, residing at Denver, 1n the county of Arapahoe and State of Colorado, have invented a new and useful Oar- Coupler, of which the following is a specification.

This invention relates to car-couplings, and moreespecially to that class thereof known as pin-supports, and the object of the same 1s to effect certain improvements in car-couplings of this character.

To this end the invention consists in the specific details of construction hereinafter more I5 fully described and claimed, and as illustrated on the two sheets of drawings, wherein Figure 1 is a side elevation, and Fig. 2 a front elevation, of this improved car-coupling, with the pin in its lowered position. Fig. 3 is a central longitudinal section of the drawbar and draw-head, showing the pin raised. Fig. 4 is an enlarged perspective detail'of the supporting-catch. Fig. 5 is a plan view. Referring to the said drawings, the letter L 5 designates the frame or casing within which the draw-bar M is secured, said draw-bar having a vertical eye D at its front end.

L are longitudinal bars of the casing, outside of which are arranged stays M, and V 3 is a transverse bolt passing through the front ends of these stays, through L-shaped straps N at the corners of the casing, through the rear end of the draw-head A, and through the eye D. Said rear end of the draw-head is provided with a horizontal eye D, whereby the draw-head is allowed a slight longitudinal movement on the transverse bolt V. The rear end of the draw-head is bifurcated and loosely embraces the eye D, whereby it is al- 4 lowed a slight vertical movement. Through the draw-head is a bolt R, which'passes also through slots 0 in the straps N, and Whose ends are connected by contractile springs B with the front end of the frame. This per- 4 5 mits the draw-head to have a slight longitudinal movement, so that the eye D will slide over the bolt ,V.

The interior of the mouth of the draw-head coupled to another which is higher or lower.

Through the draw-head moves a vertical pin P, which passes through the link in the usual manner and is adapted to lock the same in the draw-head. The latter is about balanced on its bolt B when the link is in its front end, so that-it shall have a rocking motion over said bolt and will thereby afford a very steady and even draft for the cars as they rise and fall under the conditions of ordinary railroad travel.

On the upper side of the draw-head is a bracket K, and I preferably connect to this bracket a laterally-extending supplemental bracket F.

E is a horizontal rod, having depending perforated ears e, which are pivotally connected by bolts to the upper ends of the brackets, and this arm has a forward extension E, pivotallyconnected by a link J with the upper end of the pin P. \Vhen the handle J at the outer end of this rod is turned by an operator standing alongside the track,- it is obvious the pin will be raised.

H is a short arm projecting from the rod E, and 1-1 is a rod pivoted to the arm H and extending upwardly to the top of the car, if the latter be a box-car, and there provided with a handle J When this handle is drawn upon, the rod E will be oscillated to raise the arm E and the pin P the same as if the handle J were twisted.

The letter G designates a catch, which is of approximately L shape, with stub-shafts g projecting from its angle, and the said shafts are journaled in notches Q in the bracket K. The latter is bifurcated, as shown, and within such bifurcation the catch G works. Upon the inner end of the arm E is a projecting tongue T of about the shape shown, which engages with a notch U in the upper end of the catch G when the arm E is raised and immediately below this tongue is a longer tongue or projection T, as shown. The inner end of the catch is weighted, as at W".

IVith the above construction of parts, when two draw-heads come together the bolts R move to the rear in the slot 0 and dist nd the springs B, the longitudinal eyes D moving over the bolts V in a manner which will be clear. The link may be tilted to cause it to enter the mouth of an approaching draw-head, and the entire draw-head may be rocked upon its bolt R, which passes through it at about its center. The link may be engaged with or disengaged from the pin by moving the latter in the manner above described, and when the pin is raised the tongue T engages the notch U of the catch G and holds it raised. When it is desired to drop the pin to pass it through a link, the handle J or J is further slightly moved, so as to cause the projection T to throw the upper .end of the catch G forward to disengage the notch U from the tongue T, and before the weighted end W of the catch can fall again the rod E is turned in the opposite direction to shoot the pin downwardly through the link.

hat is claimed as new is- 1. In a car-coupling, the combination, with a draw-bar M, havinga vertical eye D in its front end, a draw-head A having a longitudinal eye D in its bifurcated rear end, loosely embracing the eye in the draw-bar, and a bolt through said eyes, of a transverse pivot-bolt B through said draw-head, and springs B, connecting this bolt with the car, as and for the purpose set forth.

2. In a car-coupling, the combination, with the draw-head having a vertical pin-opening, a pin therein, alink,and a bifurcated bracket in rear of said opening, of an arm E, pivoted in the upper end of said bracket and connected at its outer end with the link, said arm having a tongue T and a projection T, an L-shaped catch G, having aweighted rear end, said catch being pivoted in the bracket and its upper end provided with a notch U, adapted to engage the tongue above said projection, and means, substantially as described, for operating the arm'E, all as and for the purpose hereinbeforc set forth.

3. In a car-coupling, the combination, with the draw-head provided with a vertical pinopening, the pinin said opening, and the link, of a bracket rising from the draw-head in rear of the pin, a laterally-extendin g supplemental bracket mounted thereon, a transverse rod having depending perforated ears, bolts passing through said perforations and through the brackets, an arm projecting forwardly from said rod and connected with the pin, and means, substantially as described, for operating said rod, as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my ownI have hereto aflixed my signature in presence of two witnesses.

GEORGE A. KENNEDY.
