OTIS HOOD, OF ONSET, MASSACHUSETTS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0. 479,881, dated August 2, 1892. Application filed April 4, 1892. Serial No. 427,590. (No model.)

To all whom it may concern.-

Be it known that I, OTIS HOOD, a citizen of the United States, and a resident of Onset,in the county of Plymouth and State of Massachusetts, have invented new and useful Improvements in Oar-Oouplings, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in car-couplings for the purpose of automatically coupling railway-cars together without danger or injury to the operator, and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a side elevation of a pair of cars coupled together by my improved device. Fig. 2 represents a top plan of the improved car-coupler shown as coupled to another one of like construction. Fig. 3 represents a longitudinal section of Fig. 2 Fig.4 represents a longitudinal section of the improved car-couplers shown in the act of being coupled together, and Fig. 5 represents a detail side View of the outer end of one of the pivoted shackle-frames.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

A A represent a pair of railway-cars, on which E B are the hunters or draw bars, having flaring mouths or link-sockets B B, as is usual in car-coupling devices. To the top of each draw-bar is pivoted at b a swinging shackle-frame 0, having lateral slots 0, in which is loosely held the cross-bar D,having secured toit adownwardly-projecting shacklepin D, as shown in the drawings.

On opposite sides of the cross-bar D are located in the slot 0 elastic packings C" O for the purpose of allowing the shackle-frame O to yield longitudinally when the cars are coupled together, and thus relieve the said shackle-frame from undue strain.

E E are upwardly-projecting cams or inclines on the outer ends of the draw-barsBB, which serve to elevate the shackle-frame on the opposite bunter as the cars approach each other, and for this purpose I provide the outer end of each shackle-frame with one or more anti-friction-rollersffi which during the coupling operation come in contact with the wedge E E, causing said shackle-frame O and its shackle-pin D to rise sufficiently upward to enable the pin D to pass between the said wedges E E above the mouth B, and finally to be automatically guided into a perforation b in the draw-bar and through the link G, which is connected in its opposite end to the opposite draw-bar by means of a pin 1)", as shown in the drawings. Each shackle-frame O has an anti-friction roller f journaled on it back of the shaokle-pin'D for the purpose of guiding the latter into the perforation b after said shackle-frame has been raised to its highest point, when said roller f will come in contact with and roll against the rear face of the wedges E E. The cars can be unshackled without going between them simply by pulling on a cord H, attached to the shackle-frame, as shown in the drawings.

' This improved car-coupler maybe coupled to any of the ordinary draw-bars simply by swinging the shackle-frame C out of operative position and coupling the link by the usual link-pins.

It will be noticed that each draw-bar has a pivoted shackle-frame adapted to be actuated by wedges on the opposite drawbar, the shackle-frame on one draw-bar being arranged to one side of the shackle-frame on the opposite draw-bar, so as to provide for automatic coupling of one car with either of the ends of another car.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. The herein-described automatic car-coupler, consisting of draw-bars having flaring mouths and a link connected to one of the draw-bars, combined with ashackle-frame pivoted to one of the draw-bars and having a yielding shackle bar and pin mounted in slots in said shackle-frame, one or more anti-friction rollers on the latter, and wedge-shaped projections and a locking-perforation on the opposite draw-bar, substantially as and for the purpose set forth.

2. The herein-described automatic car-coupler, consisting of a pair of flaring-mouthed draw-bars, each one having a link adapted to be connected to the opposite draw-bar, apivbar, substantially as and for the purpose set oted shackleframe, a yielding shackle bar forth. and pin mounted in slots in said shackle In testimony whereof I have signed my frame, one or more anti-friction rollers on the name to this specification, in the presence of 5 latter, and wedges and a locking-perforation two subscribing witnesses, on this 1st day of I 5 for automatically guiding the locking-pin on March, A.
