18 Claims.

This invention relates to uncoupling mechanisms for railway cars and has for an object the provision of new and improved uncoupling mechanism, simple in construction, reliable in action, and eiTectively prevented from accidental operation to uncoupling position. In this connection the invention includes supporting means cooperating with an uncoupling rod in a novel manner, whereby the parts may be assembled with facility, undesired actuation 'of the rod is precluded, and intended operation of the rod to uncoupling position may be expeditiously accomplished. A further object resides in provision of an uncoupling mechanism possessing the foregoing advantages :and in which the uncoupling rod is at the same time supported for movement laterally with the coupler. The invention also provides a novel and efi'icient uncoupling mechanism which may be readily applied to car couplers of the rotary 'bottom-operated type. Other features and advantages of the invention will be hereinafter described and claimed.

In the accompanying drawings:

Fig. 1 is a view in front elevation of an uncoupling mechanism embodying my invention, with associated car and coupler structure, of :conventional type, shown in dot-dash lines.

Fig. 2 is a top plan view illustrating the supporting bracket together with the adjacent portion of the uncoupling rod.

Fig. 4 is a View similar .to Fig. 3, but showing the uncoupling rod in knuckle thrown position. I Fig. 5 is a front elevational view showing the bracket on a slightly larger scale and illustrating in conjunction therewith a modified form of uncoupling rod.

Fig. 6 is a vertical of Fig. 5.

Referring to the drawings there is indicated in-dot-dash lines at ,A a portionof a conventional car structure in which is mounted in the usual manner a coupler B of known form. Said coupler includes a lever 5 (Fig. 3) pivoted at one end on a trunnion supported by lugs 6, G, and connected at its other end to a link i for operating the coupler lock. These elements are well-known in the art, and further description thereof is unnecessary to an understanding of my invention.

In carrying out my invention I secure to the car a bracket 8, comprising a web 9 and flanges Ill], ll adapted to lie against corresponding portions of the car frame work andfastened thereto sectional view on line 66 in any suitable way. This bracket cooperates with an uncoupling rod l 2 having one end portion 'bent into the form of an elongated loop, the lower element of which is the portion ii of said rod and the upper element of which loop is designated by the numeral I3. From the loop element J3 there extends downwardly the handle portion M, which, as shown, is bent laterally at the lower end to provide a portion l5 adapted to be grasped by the operator. The opposite end of the rod I2 is first bent to provide a laterally extending portion l6 (Figs. 3 and 6) and is then bent into the form of a hook I1. is adapted to overlie the lever 5 and the hook I! to extend downwardly through one side of said lever and thence to pass under the same, whereby said lever is operatively engaged by the rod por- .tions 56, H as shown in Fig. 3.

The bracket 8 is provided with an upwardly facing recessed portion l8 which forms a bearing for receiving the lower loop portion l2 of the uncoupling rod when the latter is in the normal unoperated position, as shown in Figs. 1 and 3. The shoulder 19 of bearing portion l8 assists in preventing turning of the uncoupling rod into uncoupling position so long as said rod portion I2 is seated in said bearing. Extending upwardly and outwardly from shoulder I9 is a ledge 20.

Spaced above the bearing portion 18 isa downwardly facing recessed portion 2| of the bracket adapted to receive and form a bearing for the upper element 53 of the loop. A downwardly and outwardly inclined surface 22 of the bracket extends from the bearing portion 2| to the bearing portion l8. In the bracket there is further provided a hole 23 for the reception of a bolt 24 to maintain the uncoupling rod in position when once assembled. Said opening 23 is provided at its forward end with a flared portion 23', which permits the bolt to be readily inserted in said opening, despite the sloping ledge 20 which extends in front of the opening. In other words, the wider recess provided by the flared portion 23' permits the bolt 24 to be tipped slightly upwardly and passed into the opening 23.

To assemble the rod in operative position in the bracket, the end portions l6, I! of said rod are first hooked over and around the rotary uncoupling lever 5 and then the upper element l3 of the loop at the outer end of said rod is placed in the bearing portion 2| of the bracket, the rod then assuming the position shown in Fig. 4. Bolt 24 is then placed in position and the rod thereby locked in place. In this connection it The portion l6 may be observed that the shortest distance from the head of the bolt 24 t0 the jaw 25 of the bearing portion 2! is less than the diameter or thickness of the rod, whereby the latter is locked against withdrawal from the bracket so long as the bolt 24 is in the opening 23. The head of said bolt seats against a shoulder 26 at the front of said opening, and said bolt may be fastened in position by the nut 24" which may be locked in place in any suitable or conventional manner.

When the handle M is released with the rod in the position shown in Fig. 4 the lower portion !2 of the loop drops into engagement with sloping ledge 26 on the bracket and slides down said ledge into the position shown in Fig. 3, due to the weight of the rod and its portion Hi. In the position shown in Fig. 3 the loop portion l2 has dropped into engagement with the bearing recess E3 while the upper loop element i3 has dropped out of seating engagement with the upper bearing 2|. At the same time, the jaw 25 overlaps said loop element l3, and the bolt head 24, in cooperation with said jaw, precludes removal of the rod from the bracket. Also in the position of the parts in Fig. 3 the vertical surface or shoulder !9 of the bearing portion l8 prevents the loop element l2 from moving forwardly and thus precludes the rod from swinging to uncoupling position. Sudden jolts that would tend to swing the handle I l forwardly will thus have no effect upon the uncoupling rod and the latter therefore cannot cause undesired unlocking of the coupler.

To operate the rod to uncoupling position, the operator grasps the projection i5 of the handle portion I l and lifts upwardly until the upper element 53 of the loop seats in the upper bearing 2|, at which time the lower element l2 of said loop is clear of the shoulder E9. The handle l4 may now be swung forwardly to unlock the coupler. After the coupler is unlocked and said handle released, the uncoupling rod will assume its normal locked position, shown in Fig. 3, without further attention by the operator. If it is desired, in addition to unlocking the coupler, to throw the knuckle to open position the handle I4 is swung further forwardly to substantially the position shown in Fig. 4, where the knuckle is shown open; and, upon release, said handle and associated rod portions will descend into their normal Fig. 3 position when the knuckle is fully closed.

It will be observed that the portions l2, l3 form an elongated loop which seats slidably in the bracket 8 and permits the uncoupling rod to move laterally with lateral movements of the coupler.

In Figs. 5 and 6 there is shown in conjunction with the bracket 8 an uncoupling rod 26 of modified form. The end of this rod which engages the rotary unlocking lever of the coupler is the same as that of the rod l2, but the portion of the rod 26 which engages the bracket 8 is of modified construction. Thus said rod 26 is bent downwardly to form the portion 2i, then laterally at 28, then upwardly and inwardly to provide the portion 29, and finally is bent outwardly to form the portion 30 which may extend in overlapping relation to the portion Zl. The portion 30, and the portion 2d of the rod 26 immediately thereabove constitute upper and lower elements of an elongated loop portion of the rod, similar to elements l2 and i3 of the loop formed in rod l2; the element 38 cooperating with the lower bearing portion l8 of bracket 8 in the same manner as does said rod portion !2, and portion 26' cooperating with the upper bearing 2| in the same way as does element I3. At the same time, the elements 2l3il provide an effective operating handle no part of which projects into posi tion for catching in the operators clothing or causing other possible damage.

The terms and expressions which I have employed are used as terms of description and not of limitation, and I have no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described or portions thereof, but recognize that various modifications are possible within the scope of the invention claimed.
