9 Claims.

The invention relates to means or device to operate a railway car coupler from adjacent the side of the car as required by the safety appliance act under the Interstate Commerce Commission law, and one of the objects of the invention is to provide such a device wherein the lateral service movements of the coupler will not cause the handle of the device to move sidewise of the car so that such handle is always in substantially the same relation to the side of. the car where it can be grabbed by the trainman, and furthermore always is within the limitations prescribed by the above mentioned safety appliance act.

My device is an improvement upon the constructionshown in Kinne Patent No. 1,985,036 of December 18, 1934:, one ofthe improved features being to increase the clearance between the inner end of the operating rod or member and the coupler to reduce the friction therebetween, which friction is caused by varying heights 'of couplers and improper height of the supporting bracket from the rail.

Another object and improvement is to provide an operating rod or member comprising two pieces which are hinged together so that one rod or member may be applied to any one of several railway cars of various widths without altering the car, position. of the coupler or the operating member and furthermore without altering the relation of the supporting bracket to the side wall of the car. Such a device reduces the cost thereof by permitting quantity production by the maker and quantity storage by the user. Inventories are also reduced. In other Words, standardization.

Another object of the invention is to provide a hinge connection between the two'pieces comprising the operating member for movement in substantially a vertical plane only, and if a hinged connection is not used to provide means to limit the angular movement of the two component pieces in a substantially horizontal plane.

In the drawings;

Figs. 1 and 2 show a typical application to a railway car.

Fig. 3 shows a side view of a coupler by itself.

Figs. 4 and 5 show a modified structure.

Figs. 6 and 7 show another modified structure. The drawings show the coupler lock lifter 2 pivotally supported by the coupler head 3 at 4 and operatively connected to the coupler look at 5. A typical coupler of the kind to which my device is especially adaptable is shown in Kinne Patent No. 1,639,300 of August 16, 1927, and Kinne Patent No. 1,985,036 of December 18, 1934.

The outer end of the two piece operating member is rotatably supported by the outer bracket 10 mounted upon the car adjacent the side wall of. the car and the inner end thereof is directly connected to and supported by the lifter arm 2. The two piece operating member is connected to the lifter arm intermediate its points of connection to the coupler head (4) and the coupler lock (5) so that a portion of the weight of the two piece operating member tends to keep the coupler look from unlocking or creeping.

The outer piece (29) and the inner piece (M) of the two piece operating member are hinged together for angular movement in a substantially vertical plane so that the coupler may move laterally of the car without disturbing the handle 22. The handle 22 may be offset, as shown at 24, to prevent the outer piece 20 from moving sidewise of the car in the bracket I0. The joint between the pieces 20 and 2| is preferably lower than the connection between the inner piece 2| and the lifter arm 2 to assure a hinge action between the two pieces 20 and 21 when the coupler moves laterally. v

The inner and outer pieces are also rotatively connected together; that is, so that the rotation of one piece rotates the other piece.

In Figs. 1 and 2 the hinged rotatable joint between the two pieces of. the operating member is shown as a pair of interengaging eyes SIS-3i.

Figs. 4 and 5 show a modified joint wherein one piece is provided with a flat part 34 fitting between a pair of jaws 35 on the other part and pivotally secured thereto by the pin 36.

Figs. 6 and '7 show a modification wherein the joint comprises an eye 40 on one of the pieces and a three pronged fork on the other piece with the middle prong 4i passing through the eye All and with the two outer prongs 42 engaging the sides of the eye 40 to cause rotation of both pieces upon rotation of one of the pieces. Some means are provided to retain the middle prong M in the eye; for instance, the middle prong may be bent to encircle a portion of the eye, as shown at 44. The outer prongs 42 maybe bent downwardly 35) for loose engagement with the opposite sides of the piece 46 to restrict the angular movement of the pieces in a substantially horizontal plane; that is, to prevent undue bodily swinging movement of the two piece operating member.

The accompanying drawings illustrate the preferred form of the invention, though it is to be understood that the invention is not 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.
