CAR-COUPLING.

SBECIFICATION forming part of Letters Patent No. 716,571, dated December 23, 1902.

Application filed October 14. 1901. Serial No. 78,576. llo model.)

To all whom it may concern:

Be it known that we, WILLIAM A. MORE- LAND and HARRY B. BEDDING, citizens of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain newand useful Improvements in Oar- Couplers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in car-couplers, and has for its main object to provide a novel and effective means for supporting the couplingpin of what is commonly known as the automatic coupler.

Briefly described, our invention consists in the especial construction of the coupling-pin, a portion of the body being cut away and having pivoted thereto a supportingpin which when the coupling-pin is elevated to the position so that the couplers may be engaged the coupling-pin is retained in its position until such a time as the tailpiece of the engaging coupler moves the supporting-pin from the vertical to the horizontal position and allows the coupling-pin to descend into the coupling position.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a top plan view of an automatic coupler having our improvements applied thereto. Fig. 2 is a Vertical sectional View of the coupler, taken on line 2 2 of Fig. l and showing the pin in an elevated position. Fig. 3 is a sectional view similar to Fig. 2 and showing the position of the coupling-pin and tailpiece,so that the couplers maybe engaged. Fig. 4. is a cross-sectional viewof the coupler, showing the coupling-pin in locked position; and Fig. 5 is a view in perspective of the coupling-pin.

In the accompanying drawings, 1 indicates the barrel, which is suitably secured inthe draw-head of the car in any preferred manner, and 2 indicates the head of the coupler, having a jaw 3 and the knuckle 4. In the knuckle 4 is journaled a horn 5, which has an integral tailpiece 6, said tailpiece having its rear end curved outwardly, as at 7, and arranged in an opening 8 in the side wall of the coupler-head.

9 indicates the coupling-pin, having its lower portion cut away, as at 10, and provided with a recess 11, in which is pivotally mounted a supporting-pin 12. The lower end of the supporting-pin is provided with the enlarged portion or lug 13, adapted to normally hold the coupling-pin 9 in an elevated position, as shown in Fig. 2 of the drawings. The coupling-pint) is provided in its end.with a slidable lockingarm 14, which lies in a recess formed in one side of the pin and has its lower end formed with a lug 15, adapted to project beyond the face of the pin when 'the latter is in a coupled position, as shown in Fig. A of the drawings. The locking-arm 14 has its upper end enlarged, as at 16. A pin 17 extends through the said upper end of the locking-arm 14. and also through the slot 18 in the upper end of the couplingpin 9. 19 indicates the clevis, pivotally connected to the opposite ends of the said pin 17. It will thus be understood that an upward pull on the clevis draws the locking-arm 14 within its recess in'the coupling-pin, so that the latter is free to be elevated.

In operation the pin is elevated, as shown in Fig. 2 of the drawings, and when in this position the supporting-pin 12 hangs vertically, so as to support the coupling pin. When it is desired to couple the cars, the horn 5 is swung outward, and thereby causing the tailpiece 6 to strike the supporting-pin 12, which will assume the position shown in Fig. 3 of the drawings. The tailpiece and horn when the cars are coupled are in the position shown in Fig. 4 of the drawings. This operation is as follows: The engaging horn strikes the tailpiece 6 and swings the same rearwardly, and thereby permitting the couplingpin to drop or assume a locked position. Further, it will be observed that as thev couplingpin assumes a locked position the lower enlarged end of the locking-arm 14 is thrown outwardly, and thereby preventing the accidental displacement of the pin.

In order that the coupling may be readily removed from the coupler-head,weprovide the opening therefor with a communicating slot 20, through which the lower end of the supporting-pin 12 is adapted to pass.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. In a car-coupler, the combination of a draw-head, a pivoted knuckle, a coupling-pin having its lower portion cut away, a supporting-pin pivotally mounted in the cut-away portion of the said coupling-pin, and adapted to hang in a vertical position and engage the base of the opening of the draw-head to hold the coupling-pin in an elevated position, and a vertically-sliding locking-arm, mounted in the upper end of the said coupling-pin, substantially as described.

2. In a car-coupler, the combination of a draw-head, a pivotal knuckle, a coupling-pin having its lower portion cut away and provided in its upper end with a vertical recess, a supporting-pin pivotally mounted in the cut-away portion of said coupling-pin and adapted when the coupling-pin is elevated to hang in a vertical position and support said coupling-pin, a vertically-slidinglocking-arm mounted in the recess in the upper end of the coupling-pin, and means connected to the locking-arm for elevating the latter to disengage same and permit the elevating of the coupling-pin, substantially as described.

In testimony whereof we affix our signatures in the presence oftwo witnesses.
