UNCOUPLINVBA- DEVICE.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed January 15, 1920. Serial No. 351,715.

State ofNew'Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in Uncoupling Devices,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and to usethe same, reference being had to the accompanying drawings, which illustratethe preferred form of the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings: 1

Figure 1 is a front elevational view of a portion of acar end showing my invention in position thereon;

Fig. 2 is a plan view ofthe same;

Fig. 3 is an enlarged fragmentary view of the pivoting mechanism looking in the direction indicated by arrow 3 in Fig.2; and

Fig. 4 is a plan view of the same looking in the direction indicated by arrow 4 in Fig. 3.

i The object. of my invention is to provide an uncoupling mechanism of the two-lever type in which; the levers are held in assembled position on the car bymeans of an interlocking fulcrum bracket on one of said levers and a supporting fulcrum on the car.

Other objects and advantages will appear in connection with the drawings in which 10 designates-an end ofa car equipped with my invention; 11, the car coupler provided with the usual locking-pin 12; 13 represents the operating lever of the uncoupling mecha nism, and 14 the pin lifting lever. Operating lever 13 is secured to an extension form ing a fulcrum bracket 15 adapted to receive supporting fulcrum 16 on the car.

The fulcrum bracket 15 is formed with a lever attaching flange 17 terminating in sleeve 18 for receiving the fulcrum 16, and a superposed stud 19 rising from abase-plate 20. An overhanging ledge portion 21 is projected from upper side of stud for engaging pin lifting lever 14. In the. embodiment shown the ledge 21 is extended downwardly to the base plate 20, to give the bracket greater stability during the pin lifting op eration. .The overhanging ledge portion 21 is spaced from stud 19 to provide a passageway 22 for the open book 23 of the pin lever 14 as shown in Figs. 3 and 4.

The pin lifting lever 14 is flexibly con-l nected with operating lever 13 through the medium of the open hook 23 moving between ledge '21 and base plate 20, and embracing stud 19 about which the pin lever pivots in response to the longitudinal movements of the coupler. Separation of pin lever and stud 19 is prevented by the overhanging ledge 21 which engages the upper side of the hook 23 during the pin lifting operation. This ledge and base plate 20 of the fulcrum bracket provide the means for the transmission of power from the operating lever 13 tothe couplerpin 12 through pin lever 14, for when the operating lever is drawn downwardly as shown by broken lines in Fig. 1, the under sideof the ledge bears upon the upper edge of the hook 23 while the underside thereof rests upon base plate 20 above the fulcrum 16.

It will be noted that the pivot stud 19 is positioned on operating lever 13 some dis tance from fulcrum 16 to provide sufficient overlap of levers 13 and 14 for transmitting power from one to the other. without unduly straining the connections. Base plate 20 is provided with an upstanding abutment 24 above the fulcrum 16 designed to engage said lever to check abnormal lateral movement thereof, while stop lug 25 on fulcrum 16 is in position to engage the underside of base plate 20 as shown in Fig. 3 to limit downward sweep of operating lever 13 after raising coupler pin 12 to release position indicated by broken lines in Fig. 1.

bolt 26 or the like, extending through sleeve 18 of the fulcrum bracket, washer 27, fulcrum 16, and a fulcrum supporting bracket 28 secured to the car. With the mechanism held in position by the bolt 26 as indicated, the parts thereof are interlocked but with such flexibility of connection between said parts as to permitnecessary lateral. and longitudinal play of the coupler.

It will be noted that the hook 23 of pin lever 14 is adapted to be engaged by ledge 21 of the fulcrum bracket and base plate 20 at points substantially in line with pivot stud 19 to prevent rotation of the lever about its g i d nel axis and transmit a balanced by deflectingthe' hook 23 from the body of the'lever to overcome eccentricity in the application of the pin lifting forceas above described.

.With the mechanism held in position by a single securing element the difiiculty heretofore experienced in disassambling worn, or damaged parts is largely overcome. The parts :are' connected by interlocking, and no special tools are required to assemble them.

What I claim is:

1. In an uncoupling device comprising operating and pin-lifting levers, a supporting fulcrum, and a fulcrum-bracket adapted to receive said fulcrum and flexibly connect said'levers so that said levers use said fulcrum in common.

'2."In an uncoupling device comprising operating and pin-lifting levers, a supporting fulcrum, and a fulcrum bracket carrying one of said levers and adapted to receive said fulcrum, said bracket including means for connecting said levers so that said levers use said fulcrum in common.

35111 an uncoupling device comprising operating and pin-lifting levers, a support ing fulcrum, and a fulcrum bracket adapted to receivesaid fulcrum and connect said levers so that said levers use'said fulcrum in common.

4:. In an uncoupling mechanism comprising operating and pin-lifting levers, a supporting fulcrum, a fulcrum bracket carrying'one of said'levers and sleeved to receive said fulcrum,- said bracket beingadapted to provide means for flexibly engaging the other of'said levers so that said levers use said fulcrum common;

.5. In an uncoupling mechanism comprising a plurality of levers, a'fulcrum common to said levers, a fulcrum bracket on one of said levers sleeved to receive said fulcrum and providing a connection for the other of' said levers, said levers overlapping between said connection and the fulcrum.

. 6. In; an uncoupling. device; comprising operating and pin-lifting levers 1n overlapping'relatioma fulcrum common to said levers, said operating lever terminating in a fulcrum bracket sleeved to receive said fulcrum and'provided with 'a'superposed pivot,
