CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 502,304, dated August 1 1893.

' Application filed March 14, 1893.:

To all whom it may concern:

Be it known that we, DAVID A. LEE and cation.

The principal object of our said invention is to produce a car coupler which can be fully operated from aposition to the sides of the cars, outside of the track, and beyond danger.

Further objects are convenience of operation, durability, and security in use.

Said invention will be first fully described and then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof, and on which st'milar letters of reference indicate similar parts. Figure 1 is a side elevation of fragments of the ends of cars with couplers embodying our said invention; Fig. 2, a central sectional view through said couplers, on the dotted lines 2 2 in Figs. 3 and 5; Fig. 3, an under side plan-view; Fig. 4 a fragmentary top plan view; Fig. 5 an end elevation of one car separately, as seenfrom the dotted line 5 5 in Fig. 1, and Fig. 6 a view similar to Fig. 2, but showing the use of both links, instead of one only, as shown in the other views.

In said drawings the portions marked A represent the draw -bars; B the vertically moving pins; vG pivoted bars, and D the links. The draw-bars A are secured to the framework of the cars in any desired manner, a simple and easily understood method of attachment being shown. They are slotted underneath, for purposes presently to be described, and on the upper side have projections A in which are ways for the pins B, and which at the same time serve as bumpers, which, when the cars come together, will, (if the impact is too violent to be resisted by the usual springs, when said springs have been compressed to the determined extent,) come in contact with the frame-work ofthe car, and

prevent further movement, as will be readily understood. Within these draw-bars are suitable openings for the pins and links, as shown.

The pins B are rectangular in cross-section, and are mounted and move in ways in the draw-heads, as shown, the two positions be- Serial No. 465,863- (No model.)

ing clearly illustrated in Fig. 2. The. upper ends of said pins are bent outwardly, and extend through the slots in the projection A to the outside, where a wrist b is provided on each. Levers B mounted on pivots 12' extend from the outside of the cars to and engage with said wrists, and thus said pins may be raised by means of said levers. These levers are illustrated most clearly in Figs. 3 and 5. They are slotted where they pass over the pivots b, to permit of the necessary longitudinal movement at that point.

The bars 0 are pivoted at c, and extend up through the draw-heads. The upper ends are bent forward, and are arranged to normally come in contact with the back sides of the pins B, and thus sustain said pins in elevated positions after they are raised, until they are purposely released. Said bars extend downwardly and forwardly, and bear weights, 0, which gives them the necessary frictional contact. As will be seen most plainly in Fig. 3, these bars are adapted to be swung slightly on their pivots, and the pins B released by the forward movement of the links, when oper-' ated by the levers attached thereto, as willbe presently described. As will be seen by an inspection of the drawings, these bars 0 take a part of the service ordinarilyperformed by the pins B, as the inner ends of the links are held thereby, thus giving double strength.

The links D occupy the usual positions in v the draw-heads, butare two'in number, instead of only one, as usual. Each has an arm D which extends down through the corresponding slot in the under side of the draw-head in which it is mounted, and is connected by means of links 01 to levers D which extend across to near the outer sides of the cars, and are pivoted at (P. By means of these levers and links the links D can also be manipulated as desired from the sides of the car, and one or both can be put in use as may be desired. Thus for heavy work on long trains, especially near'the locomotives, where the strain is greatest, what is practically full double strength of attachment between the cars may be provided, where both cars are equipped with our improved coupler. At the same time the construction is such that only one link need be used if no more is required, and the links of either coupler can be used to couple to a car having the ordinary equipment, without difficulty. It will be observed that as the link is forced forward to its place, and thrust into the opposite draw-head, it comes in contact with the front side of the bar 0 in said drawhead, thus forcing it back out of contact with the pin B, and permitting the latter to drop; and pass through the link, which has entered into its place, thus securing the coupling of, the cars. A projection awill be noticed within and close to the mouth of each of the drawbars, over which the link must pass in entering the opposite draw-bar. This is provided' as a fulcrum over which the links maybe 0perated, by means of the levers D so that its extending end can be raised or lowered to suit the other car towhich the car bearing this device is to be coupled, should itbe higher or lower than said car.

Having thus fully described our said invention, what we claim as new, and desire to .se-fcure by Letters Patent, is-

1. The combination, in acarcoupler, of the. draw-head, ,the coupling link having a downwardly,projectingarm on its rear endwhich extends through a slot on the bottom side of said draw-head, anda lever connected to said armwhereby said link may be manipulated, substantially as set forth.

2. The combination, in a carcouplergof the draw-heads containing the coupling pins, pivoted barsalso in said draw-heads, twocoupling links one in each draw-head, said bars passing through said couplinglinks andserw' in g as a means to secure themat therear'end, and the coupling pins passing through the links of the opposite draw-heads and secur-t ingthem at the forward ends, wherebya doukale coupling is secured, substantially as set orth.

3. The combination, in a car coupler, of a draw bar, the rectangular coupling pin having a forwardly-extending arm, an upward projection on the draw-bar through a slot in the side of which said arm extends,a pivoted and weighted arm 0 passing through and securing the link in the draw-head and bearing against the rear side of the coupling pin B, sustaining the same until said contact is forcibly removed, substantially as set forth.

4. The combination, in a car coupler, of a draw-head, a coupling pin having a bend at its upper end, and a wrist on the end of said .bend, thedraw-head being provided with an upward extension A slotted to receive said bend or arm, levers B pivoted to the car frame attached to thewrist on theend of said bend, said wrists being slotted on their. pivots,-and said several partsbeiug arranged and operating substantiallyas-set forth.

5. The. combination, in ,a car coupler, of two draw-heads each providedwith avertically moving coupling pin, levers whereby said coupling pins are operatedrpivotedaud weighted bars 0 mounted insai'd draw-heads the upper endslwhereof come in contact with said coupling pinsland links D, one in each draw-head, and secured thereinby the ,bars 0 which passthrough them,and adapted to be connectedto the opposite draw-heads by the coupling pins Bgall substantiallyas shown and described.

Inwitnesswhereof we have hereunto set our hands andseals, at Mariettmlndian a, this lOthdayof March, AND. 1893.
