COUPLER-PIN" LIFT.

Original application filed May 31, 1923, Serial No. 642,693. Divided and this application filed August 18, 1924. Serial No. 732,635.

This invention relates to car coupling devices and more particularly to mechanism for lifting the coupling devices or looking pins for connecting cars of railway trains and the like.

One of the objects of the invention is the provision of new and improved uncoupling rigging or mechanism comprising an operating shaft or rod and a coupler pin lifting arm that may be, assembled without the use of tools and when assembled will be held in operative position without the employment of screws, bolts, or other independent fastening means.

Another object of the invention is the provision of new and improved mechanism for lifting cou Jler pins for uncoupling cars, that is composec of a minimum number of parts, that is cheap to manufacture, easily assembled, efficient in operation, easily manipulated, and that is not likely to become broken or get out of order.

Other and further objects and advantages of the invention will appear from the following description, taken in connection with the accompanying drawings, in which Fig. 1 is a plan view of a portion of a railway car showing my invention in position thereon, with parts in section and parts broken away;

Fig. 2 is a front elevation of a portion of a railway car, showing my invention in position thereon;

Fig. 3 is a side elevation of a portion of the car showing the invention in operative position; and

Figs. 4-. and 5 are detail views showing slight modifications of the connection between the lifting arm and the operating shaft.

On the drawing the reference character 10 designates a car provided with the draw bar 11, having the coupler 12 thereon, including the knuckle 13 which is adapted to be held in locked position by the coupler pin 14 as is usual in such constructions.

Since the specific features of the car construction constitute no part of the present invention, the same will not be further illusrated or described.

Journaled in suitable brackets 15 and 16 secured to the front end of the car 10 is a rock shaft 17 the outer end of which is bent laterally to form an operating handle 18 in the usual manner.

Suitable mechanism connecting the shaft 17 and the pin 14 is provided for releasing the knuckle 13. This mechanism is so con structed that it will permit longitudinal, lateral and vertical movements of the coupler relative to the car, and is preferably attached to said shaft without the aid of additional fastening means. As shown, the shaft 17 is distorted to provide a flattened portion 19 the edges of which are curved. An arm 20 is provided with a loop 21 forming a closed slot 22 for engaging said flattened portion 19.

Means are provided for permitting the loop to be slid onto the shaft 17 and for locking the same in position on the flattened portion 19. Any suitable means may be employed for this purpose. In the form of the device shown in Figs. 1, 2 and 3 the loop 21 is provided with an extended portion forming a groove 23 which extends transversely to said loop whereby the loop may be threaded on the shaft 17 by turning the same at right angles to said shaft so that the round portion 24 of said shaft will register with said groove. Suflicient clearance is provided between the upper side of the loop 21 and the shaft 17 for sliding the loop on said shaft. When the loop is slid on to the flattened portion 19 it is turned at an angle as shown at Figs. 1 and 2 whereby the same is locked to said shaft.

The loop 21 is provided with a downwardly and forwardly extending arm 25 which terminates in a laterally extending member 26 which is adaptedto engage in the eye of the pin 14. The member 26 may be reduced for engaging said eye. By means of this arrangement the coupler 12 is permitted to have a universal movement. The rotation of the rod 17 will permit it to move up and down and the sliding connection between the eye of the pin and the reduced portion or member 26 together with the pivot connection between the loop 21 and the flattened portion 19 will permit a lateral movement of the coupler in both directions, without aifecting the pin 14.

In the operation of the device the handle 18 is operated to rotate the shaft 17 which by means of the flattened portion 19 engaging in the loop 21 will elevate the arm 25 together with the pin It for releasing the knuckle 13.

The form of the device shown in Fig. 4 differs from that shown in Figs. 1, 2 and 3 in that the loop 27 which corresponds to the loop 21 of the form shown in said figures, is provided in both of its side walls with oppositely arranged grooves 28 and 29 which are adapted to accommodate the rod 17 in sliding said loop into position on said shaft.

In the form of the device shown in Fig. 5 the shaft 30 is flattened from one side only and consequently the groove 31 which corresponds to the groove 23 of the construction shown in Fig. 2 is sufficient without providing additional clearance for sliding the loop 82 along said rod into engagement with the flattened portion 33 thereof.

This application is a division of my former application, S01. No. 642,693, filed May 31, 1923, for coupler pin lift.

This invention is not limited in its application to the particular construction herein illustrated, as various changes might be made in the construction shown without departing from the spirit of this invention, or the scope of the appended claims.

I claim as my invention:

1. A coupler pin lifter comprising a rockshaft member and an arm member, a plurality of alined bearings for said rockshaft member, one of said members being provided with a distorted portion between said bearings and the other with a closed loop at one of its ends for engaging said distorted por tion, the outer end of said arm being a'dapt ed to engage a coupler pin for lifting the same when said shaft member is rotated.

2. A coupler pin lifter comprising a rockshaft, a flattened portion on said shaft, an arm, and .a loop member on one end of said arm for engaging said flattened portion, the outer end of said arm being adapted to ena coupler pin for lifting the same when said shaft is rotated.

3. A coupler pin lifter comprising a rockshaft having a comparatively straight body member, bearings engaging said body mem ber, means for rocking said body member, a coupler pin lifter arm member pivotally connected to said body member and interlocked therewith, and means integral with one of said members for holding said members in interlocked relation.

i. A coupler pin lifter comprising a rockshaft, bearings for rotatably mounting the same on the end of a car, said shaft being substantially straight between said bearings and having a distorted portion between said bearings, an arm having one end provided with slot for engaging said distorted por tion and having its other end extending substantially parallel with said shaft and adapted to engage the eye of a coupler pin, and means integral with said arm for preventing the disengagement of said shaft and arm while the latter is in operative position.

5. In a car uncoupling mechanism, a rockshaft, a coupler pin engaging arm, a connection between said shaft and said arm, said connection comprising a flattened portion on said shaft, having curved edges, an elongated opening in one end of said arm provided with curved end portions for engaging said curved edges said opening being provided with a central extension whereby when said arm is turned so that the extension of said slot extends parallel to said shaft the arm may be threaded on said shaft and may be interlocked with said flattened portion by an angular movement of said arm, said shaft and arm when interlocked having a limited pivotal movement relatively to each other.

6. In combination, a car provided with a coupler and a pin therefor, a rockshaft provided with a bent end constituting a handle for rotating said shaft, and means for journaling said shaft at the front end of said car, an arm, cooperating means on said shaft and arm for permitting said arm to slide along said shaft when said arm is in one position and for locking the same to said shaftwhen turned to another position, and means on said arm for engaging said pin for lifting the same.
