SPECIFICATION forming part of Letters Patent No.629,1'73', dated July 18, 1899. Application filed March 4, 1899. Serial No. 707,763. (No model.)

To all whom, it may concern: Beit known that I,-WILLrAn-REESE, a citizen of the United States, residing at Carnegie,

in the county of Allegheny and State of Penn-'1 Sylvania, have invented or discovered a new and useful Improvement in Car-Couplers, of which the following is a full, clear, and exact description, referencebein g had to the accom-v panyin g drawings, forming part of this speci- Io cation, in which- Figure 1 is a central longitudinal vertical section through a draw-head furnished with my improved variable-position locking-pin, the jaw being shown in section.' Fig. 2 is a cross-sectional View taken on the line 11 l1 of Fig. 1. operation of coupling on a curve.

Fig. 3 is applan view showing the showing the tail of the locking-jaw locked at Fig. 5 is a detail view coming into. contact with the locking-pin. Fig. 6 is a detail view in front elevation, partly in section, of the locking-pin, showing z 5 thetail of the jaw in engagement with the main pin, .the supplemental portion being raised. Figa-7 is a detail view ofl the supplemental sliding portion. 4

My invention relates to the class of Atwin- 3o jaw couplers conforming Lto `the Master Car- Builders standard, and has reference more particularly to the mechanism Aemployed in locking and unlocking the tail of the swinging jaw, the construction. otherwise involving 3 5 no change from the well-known type of J anney couplers.

Referring'to the drawings, 2 is the drawhead, in which is pivoted the usual swinging jaw or knuckle 3, provided with the extended 4o tailpiece 4, made with a vertical iiat face 5 on the inner side of its end and having its outer end rounded at 6 and tapered down to a rounded nose. l

The interior of the draw-head is hollow and -provided with a vertical slot 7 8 in the upper 5o extending'portion 1l is correspondingly narrowed in width.

Fig. 4 is a plan View of one draw-head, partly in section,

ASlidinglyrmounted upon thebolt at the oppositeside from the approachot' the swingi'ngtailpiece is a supplemental bolt 12, vertically movable with relation to thernain bolt and adapted to be held upwardly by the tail ofthe jaw when the backward mot-ion of the jaw is purposely arrested at such point immediately under the supplemental bolt, thereby permitting the main bolt to drop downwardly in front of the tailpiece to arrest its forward movement, but holding the jaw in a partiallyclosed position. y The object of such construcv tion is to better, adapt the coupler to use on curves, where, as shown in Fig. 3, the part-s will move readily and easily come into contact and accomplish the act of coupling if the jaw is partially opened. The supplemental bolt Al2 projects upwardly andhas a sliding bearing in therecessed head of the main bolt and is Valso provided Vwith a'vertical slot 13, into whichprojects a pin 14, mounted in the main bolt, which pin limits the downward travel of the supplemental bolt. It will be noticed that the corner or face of the supplemental bolt is slightly beveled onv the approach side, so that in the operation of entirely closing the jaw in coupling the tailpiece will ride under both the beveledportion 10 and the bottom of the supplemental bolt, causing both to rise thereby, although it will'be seen that the supple-V Inental bolt will be carried' up with the main bolt by reason of the pin lll.

In operation the tail of, the lookin g-j aw will 'ordinarily swing around, raising the main and supplemental bolts and seating itself in a closed position back of both bolts, as shown in Fig. 4:. When it is desired to set it as de- Y scribed, the head is thrown around until the tail passes beyond the beveled portion 10 o f the main bol'twhen such bolt will fall by gravity and the tail .will arrest the fallof the supplemental bolt, as in Fig. 6, and will bear Vagainst the inner face of the main bolt until thrown back to the last position in the act of coupling. Raising of both bolts is accomplished in the usual manner, the slot and pin preventing excessive downwardtravel of the supplemental bolt.

It will be noticed that a spring 15 is provided, attached to the interior of the drawhead and bearing upon the tail of the lockingl IOO jaw in such a manner as to throw it outwardly when the end of the tail is released, thus automatically opening the jaw.

I-Iaving described my invention, what I claim isl. In a car-coupling, the combination of a draw-head, a swinging jaw pivotally mounted therein having an extended tailpiece rounded at its outer end, a main locking-bolt vertically and slidingly mounted in the draw-head in the path of the swinging tailpiece'provided with a beveled shoulder, a reduced lower eX- tension and a recessed head, and a supplemental independent vertically-movable bolt mounted on the side of the main locking-bolt, projecting upwardly into the recessed head of the main locking-bolt and provided with a beveled shoulder and means for limiting its downward movement.

2. In a car-coupling, the combination of a draw-head, a swinging jaw pivotally mounted therein having an extended tailpiece rounded at its outer end, a main locking-bolt vertically and slidiugly mounted in the draw-head in the path of the swinging tailpiece provided with a beveled shoulder, a reduced lower extension, a limiting-pin and a recessed head, and a supplemental independent verticallymovable bolt mounted on the side of the main locking-bolt havinga vertical slot in engagement with the limiting-pin, a beveled lower shoulder adapted to be engaged by the tailpiece, and an upper extremity projecting into the Arecessed head of the main bolt.

3. In a car-coupling, the combination of a therein having an extended tail piece rounded at its outer end, a spring mounted in the draw-head and adapted to bear against the tailpiece when closed, a main locking-bolt vertieally and slidingly mounted in the drawhead in the path of .theswinging tailpiece provided with a beveled shoulder, a reduced lowerext-ension, a limiting-pin and a recessed head, and a supplementalindependent vertically-movable bolt mounted on the side of the mainr locking-bolt having a vertical slot in engagement with the limiting-pin, a beveled lower shoulder adapted to be engaged by the tailpiece, and an upper extremity projecting into the recessed head of the main bolt.

4e In a car-coupling, in combination with a drawhead, and a swinging jaw pivotally mounted therein having an extended tailpiece rounded at its outer en'd: the locking-bolt consisting of the main bolt 9 having a beveled shoulder 1'0, a downward extension 11, a recessed head at the upper end with means for attaching a lifting device and a limitingpin lll, with the supplemental bolt l2 beveled on its lower approach side and having a sliding bearing in the recessed head of the main bolt, a vertical slot 13 for engagement with pin 14, and adapted to operate independently of the main bolt or to be lifted with it.

In testimony whereof I have hereunto set my hand.
