CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 561,895, dated June 1896- Application filed April 2, 1896. Serial No- 585,940. (No model.)

To all whom it may concern.-

Be it known that I, FRANK G. KAMMERER, a citizen of the United States, residing at Chicago, int-he county of Cook and State of Illinois, have invented certain new and useful Improvements in Car-Couplers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to carcouplers, and particularly to a combined knuckle and coupling-pin for automatic carco'uplers of the .lanney type, and it has for its object to provide a simple, durable, and inexpensive article adapted to serve the double purpose of a hinge-pin for the knuckle and a c0upling-pin for the link; and it consists of the parts and combinations of parts hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of car-coupler provided with improved pin; Fig. 2, a detail sectional view of a portion of the draw-head and pin; and Fig. 3, a side elevation of a draw-head, showing the pin in its uncoupled position.

Similar letters refer to similar parts throu ghout the several views.

In the drawings is rcpresen ted a draw'head and the knuckle of an automatic car-coupler of the Janney type. In this type of coupler a latch is usually employed to lock the tailpiece of the knuckle back in the draw-head and the knuckle is secured between the perforated lugs of one jaw of the draw-head by a pin, on which the knuckle is free to swing. lleretofore it has been customary in order to adapt this type of coupler to couple with a link-and-pin coupling (a dutywhich it is frequently called upon to perform) to form a recess or slot in the edge of the knuckle to re ccive a link and to perforate the knuckle on a vertical line intersecting the recess or slot to receive a coupling pin which extends through the link and secures the same in place, thus forming a coupling between cars provided with the different styles or types of couplers named.

in practice it is found that the forming of the perforation for the pin in the knuckle weakens the same and renders it liable to be easily broken through by the sudden and violent jerks of the link on the pin incident to the movement of the cars while in use, and such liability to easily break being greater in the event of the pin not passing fully through the perforation.

Now it is the object of my invention to obviate the liability of fracture of the knuckle of an automatic car'coupler when coupled to a link by a pin, and l accomplish this object by providing in a single piece a combined knuckle-pin and coupling -pin adapted to form the hinge-pin by which the knuckle is secured in the draw-head and to enter behind the same between its inner face and the draw-head and extend downward past the slot in the edge of the knuckle.

In the drawings, A represents the drawhcad, B the knuckle having the slot a in its edge, and C the latch employed to lock the tailpiece of the knuckle back in the drawhead, all of which may be of the usual or desired style,

D represents my combined knuckle-pin and coupling-pin made of a single piece or bar of metal bent at right angles, as at 12, and then downwardly, as at 0, parallel to its other end, (I. The end (:1 of the bar is in practice preferably made longer than the end 0, and is in serted through the lugs e of the draw-head and through the knuckle and, if found neccssary,secured against accidental entire withdrawal by a cotter or key inserted through a perforation in its lower end. The end 0 preferably extends but a short distance beyond the lower or bottom edge of the slot a, as shown by dotted lines in Fig. 1, so as to secure a firm bearing on the inner face of the knuckle and, with the link in place, the strain comes on the knuckle, as is usual; but the whole thickness and entire depth of the knuckle is utilized in receiving and resisting the strain instead of but a fraction thereof, as is the case where the coupling-pin extends through a perforation in the knuckle.

The combined pin is provided with an eye or ring f, whereby it may be easily raised, as indicated in dotted lines, Fig. 1, to release a link, and may then be swung or turned and dropped into the position shown in Fig. in rear or to one side of the draw-head, where it is out of the way. To make a coupling, the

link is inserted through the slot a of the knuckle and the combined pin raised and swung around till its end 0 is past the knuckle, when it is dropped through the link.

Then the pinis in its uncoupled position or not in use, it may be desirable to insure its retention in the position shown in Fig. 3, in which case Iform a recess g, (see Fig. 2,) extending rearwardly from the knuckle pin opening in the top of the draw-head and a short projection h on the pin adapted to enter said recess 9, and thereby prevent the accidental swinging or turning of the pin.

Among the advantages of m y invention over the loose pin it will be observed that it provides for the pin always being at hand when needed, and that owing to its location when in use it reduces the slack olf the link and renders unnecessary the use of extra pins or blocks for this purpose.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with an automatic carcoupler having a swinging knuckle, of a combined hinge or pivot pin and coupling-pin comprising two members one of which forms the hinge or pivot pin for the knuckle and the other the coupling-pin for a link, substantially as described.

2. A combined hinge or knuckle pin an d coupling-pin for automatic car-couplers having a swinging knuckle, consisting of a single barbent upon itself and adapted to be raised and swung in a circle and provided with means for h oldin g it in its uncoupled position. substantially as described.

The combination, with an automatic carcoupler having a swinging knuckle, of a combined hinge or knuckle pin and coupling-pin comprising two members one of which forms the pivot-pin for the knuckle and the other being adapted to enter between the front edge or wall of the draw-head and the knuckle. substantially as described.

4;. The combination, with an automatic can coupler having a swinging knuckle, of a combined hinge or pivot pin and coupling-pin comprising two parallel members one of which forms the hinge or pivot pin for the knuckle and the other a coupling-pin for a link, and means for retaining the coupling-pin in its u ncoupled position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
