AARON B. ALLEN, OF PUEBLO, COLORADO.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 430,460, dated June 17, 1890.

Application filed January 29, 1890. serial No. 338,473. (No model.)

State of Colorado, have invented certainnewand useful Improvements in Oar-Couplings, of which the following is aspecification, reference being had therein to the accompanyin g drawin This invention relates to certain improvements in car-couplings; and itconsists of the novel construction and combination of parts, as will appear from the following description and accompanying drawings, in which- Figure 1 is a plan view of my coupling in use, parts being broken away. Fig. 2 is a horizontal section thereof. Fig. 3 is a front elevation of the same. Fig. 4 is a detail perspective view of the lever, and Fig. 5 is a horizontal section showing my coupling uncoupled.

In carrying out my invention I provide a head or casting A, which is approximately U-shaped and provided with a shank or stem portion a, having an aperture 1). This apertured shank or stem portion in practice being adapted to engage the link-chamber of the draw-head of the ordinary form of car-coupling, provides, consequently, for the ready application of my coupling thereto, the aperture 1) serving to receive the ordinary couplingpin, which, therefore, connects the two drawheads together.

B is the coupling-hook, which is approximately right-angled in shape and pivoted at its angle in one of the arms of the draw-head A, said arm being bifurcated or slotted toreceive said hook. This hook engages in the coupling operation, its counterpart being on a duplicate head or casting.

O is a lever, which is lmuckle-jointed or pivoted to the inner end of the hook B and normally rests in a transverse groove or slot 0 in the head or casting A, its outer end projecting through one arm of said casting within convenient reach for manipulation in ctfecting the uncoupling operation. The lever Chas at its lower edge a short distance i11- ward from its outer end a shoulder (I, which engages a stop 6, provided upon the casting or head A, immediately at one side of the plane of the slot or groove 0, to effect the securement of said lever in a locked position,

retaining the hook in its engaging orcoupled 6, which will permit the lever to be drawn outward, by doing which the coupling-hook B is thrown outward when disengagement thereof from its fellow hook is permitted, and consequently the uncoupling of the cars. The opposite manipulation of said parts effects the coupling of the ears.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent. is-

1. In a car-coupling, the coupling-hook hung at its angle and having its inner end recessed, in combination with the couplinglever pivoted at one end in the slot of the coupling-hook, substantially as shown and described.

2. In a car-coupling, the coupling-hook hung at its angle and having its inner end recessed, in combination with the couplinglever pivoted at one end in the recess of the coupling-hook and having a shoulder on its under side which engages a stop, substantially as shown and described.

3. In a car-coupling, the coupling-hook hung at its angle in a bifurcation in the draw-head and having its inner end recessed, in combination with the coupling-lever pivoted at one end in the recess of the couplinghook and having ashoulder on its under side designed to engage a stop in a recess in theback of the draw-head, the lever in continuation being projected through an opening in the side of the draw-head which serves as a guide, substantially as shown and described.

4. In a car-coupling the coupling-hook pivoted at its angle, the lever connected thereto in a slot or bifurcation of the drawhead and having a shoulder on its under side engaging the stop in said slot, substantially as shown and described.

5. The car-coupling having the swinging coupling-hook hung in the draw-head and having the uncoupling-lever provided witha side of the cars, substantially as shown and I0 shoulder engaging a stop on the draw-head, described. substantially as shown and described. In testimony whereof I affix my signature 6. The car-coupling having the swinging in presence of two Witnesses. 5 coupling-hook provided with the uncouplinglever'knuckle-jointed or pivoted to said hook, AARON B. ALLEN. and provided with a shoulder engaginga stop WVitnesses:

on the draw-heed and projecting through the CHARLES V. STICKNEY,

latter to permit its manipulation from the A. E. COLBURN.
