12 Claims.
This invention relates to uncoupling mechanism for railway car couplers.
An object of my invention is to provide a simple and efllcient mechanism for operating the coupler from either side of the car.
Another object is to provide an uncoupling mechanism which, in addition to affording a high degree of flexibility to allow for the various movements of the coupler in service, is adapted to be locked when in unoperated position to preclude any accidental upward swinging of its parts as would result in unlocking of the coupler.
A-further object is to provide an uncoupling arrangement providing for operation of the coupler from either side of the car, the mechanism on either side bing operable to effect uncoupling while the mechanism on the other side remains locked.
Other objects and advantages of my invention will appear from the following description taken in conjunction with the drawings, in which:
Figure 1 is a plan view of the uncoupling mechanism applied to a car coupler.
Figure 2 is a front elevational view of the mechanism shown in Figure 1.

Figure 9 is a sectional view of the connector member taken along the line 9-8 of Figure 8.
Figure 10 is a sectional view taken along line Ill-40 of Figure 8.
Figure 11 is a view showing a modified form of the invention; and
Figure 12 is a view taken along line |2-l2 of Figure 11.
Referring to the drawings, there is shown a coupler Ill and car body ll. Pivotally attached to the car body by means of brackets l2 and I3 is the mechanism is in reposed position, key I! extends into slot 19, locking shaft l5 against accidental rotation. Movement of pivotal member I! laterally of the car is limited by portions and 2| of the member located adjacent the brackets.
Bearing portion 22 of bracket I2 has a kidneyshaped opening 23 receiving shaft l5. This opening is so positioned that when the shaft is in the bottom part thereof, key I! projects into slot l9. To rotate shaft l5, as during uncoupling, the outer end of the shaft is first raised by means of handle i 6 to the upper portion of opening 23 so as to withdraw key H from slot l9, after which the shaft is free to be pivoted. Projection 24 in opening 23 serves to oppose any accidental upward movement of the shaft and in no way interferes with manual raising of the shaft to the upper end of the opening.
Adjacent slot l9 bracket I2 is formed with an upwardly and outwardly extending surface 25 which facilitates returning of key I! from its raised position during uncoupling to locked position within slot I! when han'dle I6 is released. The raised positions of the shaft and handle are shown in dot-dash in Figure '7. Upon release of the handle, key ll engages surface 25 and slides downwardly into slot l9 as the handle swings to its lowered position, thereby locking the mechanism.
Transmission of the rotative force from shaft l5 to the coupler lock mechanism is accomplished by means of connector member 30 slidabiy mounted on the shaft and uncoupling rod 3| which is rigidly secured to the connector member. It will be clear that they key-hole opening 32 in the connector member permits movement of the member longitudinally of shaft l6 and also provides for rotation thereof with the shaft in whatever position it occupies thereon laterally of the car. Since rod 3| is thus keyed to shaft IE it cannot be swung upwardly to effect unlocking of the coupler without also causing member it to rotate therewith, and therefore, when member i4 is in locked position, rod 3! is precluded from being accidentally pivoted by flying objects or otherwise.
In order to allow for longitudinal and vertical movement of the coupler in service, wall 33 of the shaft receiving .portion of opening 32 and side and bottom walls 34 and 35 of the key receiving por-- tion of said opening are all convexly curved. It is therefore apparent that the connector member in addition to being slidably keyed to shaft I 5 may angle in both vertical and horizontal planes relative thereto. This plurality of movements of the connector member provides the degree of flexibility necessary between rod 3| and shaft L5 to allow for the displacement of the coupler which occurs in service. This flexibility is useful particularly a,sse,sae
Rod 5| is welded or otherwise made integral L with connector 55 and is of such length that when the coupler is in central position, the connector is located on the central portion of shaft i5, thereby enabling the rod to follow the coupler an equal amount in either direction transversely of the car. Furthermore, the length of shaft l5 may be increased or decreased, depending upon the amount of horizontal angling of the coupler. Also, rod 5| is formed with an offset fortion 55 which tends to maintain the rod in its reposed position. Although connector 55 and rod 3| are shown as initially separate parts, it is to be understood that a single member embodying the various features of the connector and rod as shown may be used without departing from the spirit of the invention. This single member may be produced by forming rod 5| with an arm thereon corresponding to connector 50 and similar to arm 55 on rod 55 of the modification later to be described.
The rotative force is transmitted from rod 3| to rotor lever 45 by means of hook portion 51. Lever 40 is formed with hook portions 4| by means of which the lever is pivotally connected to the laterally extending trunnions 42 on the coupler. The lever is operatively connected to lock member 43 by a link 44. Upon rotation of lever 40 the lock is raised and uncoupling is effected. Hook 5! on rod 5| is received by eye portion 45 on the lever and rotation of the latter is accomplished by the engagement of the hook with dependinglug 45 when handle I5 is swung upwardly.
It will be apparent that the uncoupling mechanism may be applied to either side of the car. In order to permit application of the device to both sides of the car and allow operation of the mechanism from either side independently of the other, rotor lever 40 is provided with eye portions 45 on each side thereof of a construction that will allow the aforesaid independent movement of the uncoupling rods. Extending laterally from each hook portion 4| of the rotor lever are the spaced arms 48 and 45 of eye 45. Joined to the outer ends of these arms is the U-shaped portion 50 which is positioned in a vertical plane with its open end extending upwards and forming a continuation of said arms, thereby providing an opening 5| which permits connecting I of hook 31 of the uncoupling rod to the eye.
It will be observed from Figure 5 that upon rotation of lever 40 to unlocked position of the coupler by means of an uncoupling rod on one side of the car the other rod is not disturbed. In Figure 5 the lever has been moved by rod 55 (similar to rod 5|) through an are greater than 90, and during this period rod 5| has remained locked in its normal position as the associated eye 45 is rotated with respect thereto. Supporting surface 52 is preferably made slightly eccentric with respect to the axis of trunnions 4| so that upon rotation of the lever to unlocked position the hook ends of both rods will be raised a small amount and will therefore tend to assist the return of the lever to its reposed position upon release of the operated rod and closing of the knuckle. It will be observed armisioinedtohook4|atapointwelle thehook portion oftheuncouplingrodsnd recesseda'sat55sotha'tsaidarmwillnot gage theihook of the non-operated rod portion 55.
While in the aforedescribed embodiment pivotal member |4 comprises a shaft portion II with a key |'l secured thereto, it will be apparent that the pivotal member may be of any suitable section other than circular so that uncoupling rod 5| which is slidably connected thereto will rotate therewith. In Figures 11 and i2 is shown a modified form of my invention in which the pivotal member 55 comprises a laterally extending supporting portion 5| rectangular in cross-section. The member is provided with trunnions 52 and 53 for pivotal mounting thereof. Trunnion 52 terminates in a handle 54 for operation of the member. Slidably and non-rotatably connected to member 55 is the uncoupling rod 55 which corresponds to rod 5| of the previous embodiment. Rod 55 is formed with an arm 55 which is shaped so as to have a rectangular opening 5'! for receiving portion 5| of member 55. The operation of this form of the invention is identical with that of the previous embodiment.
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.
