DEVICE FOR OPERATING CAR-COUPLINGS.

Application filed November 2, 1916.

To all :whom t may concern:

Be it known that we, FRANK M. TURNER and JOHN DAHLSTROM, both of the city of Pittsburgh, county of Allegheny, and State Vof Pennsylvania., have invented a new and usefulDevice for Operating Car-Couplings, of which the following is a full, clear, and

eXact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a plan view of a car-coupler provided with our operating device; Fig. 2 is a front elevation of the same; Fig. 3 is a plan view showing a modification; Fig. 4 is a front elevation of the same; Fig. 5 is a side elevation of the device shown in Fig. 1; Fig. 6 is a detached view, partly in section, of one of the pivotal supports of the adjusting yoke; and Fig. 7 is a like view of the v pivotal fulcrum of the pin operating lever.

In car couplers the coupling heads of locomotives and cars are so mounted as to be capable of lateral movement, which is necessary in rounding curves, and, owing to this movement, it becomes frequently necessary to adjust the couplers before they can be coupled one with the other. It is also necessary in coupling and uncoupling cars to raise the coupling pin.

The object of our invention is to provide a simple and effective device by means of which the coupler may be adjusted and the coupling pin raised from a point outside of the meeting faces of the cars, without danger to the operator and without interfering with the normal lateral play of the coupler.

In the drawing 2 represents a portion of the front end of a shifting engine provided with an automatic coupler, 3 and 4, which may be of ordinary construction and mounted on the engine or car in the usual manner to allow of suilicient lateral movement required in passing curves in the track. On each side of the coupler are substantially vertical adjusting arms, 5, which are disconnected with the coupler and are preferably normally out of contact with the same, but they are so connected with each other that lateral movement imparted to one arm will also be imparted to the other. This connection, in the device shown in Figs. 1 and2, is formed by the cross or yoke bar, 6, having sockets, 7, pivoted at the ends thereof, in which sockets cylindrical portions of the Specification of Letters Patent.

arms, 5, are journaled, as is shown in Fig. 2. The rear ends of the arms, 5, are similarly j ournaled in sockets, 7 which are pivoted in the seats, 8, secured to the sill or frame, 9, of the engine or car. The purpose of this construction is to permit the arms, 5, to be rigidly connected with the operating levers, 10, which must be capable of a double movement, one movement to adjust the coupler,

and the other movement to uncouple the same. These operating levers, l0, which are pivoted through the arms, 5, in the sockets, 7 extend beyond their pivotal point to and over a plate 11 which is integral with or secured to a lever arm 12 which is pivoted to a pivoted fulcrum support 13 and extends to a point over the coupling pin 14 to which it is connected by links 15.

When it is desired to adjust the coupler 3 to permit adjacent coupler heads to be coupled, the lever arm 10 is moved horizontally, as shown by dotted lines in Fig. 1, which imparts a lateral movement to the arm 5, bringing it in contact with the shank 4 to pushthe coupler to the desired position for coupling, and at the same time the outer end of the lever arm 10 may be raised, as shown by dotted lines in Fig. 2, the arm 5 turning in the socket 7, which brings the inner end of the arm 10 upon the plate 11 and depresses the same, thus lifting the coupling pin 14.

Modifications of the foregoing construcin housings 17, secured to the face of the plate 15, and is provided with handles 18 at its outer ends by means of which it may be rotated in its housings .to raise and lower the pin operating lever 12', While the coupler is adjusted by a horizontal movement of the arm 10 which brings either one of the arms 5 in contact with the head of the coupler.

The advantages of our device are that the cars may be coupled from a position outside of the meeting faces of the cars without liability of injury to the operator, the parts are simple and eifective, and the device is such as not to interfere with the normal movement and operation of the coupler.

Although We have shown certain forms of construction, We. do not desire to limit our invention thereto. f

Having thus described our invention, what We claim and desire to secure by Letters Patent is- In e device for operating car couplers, an adjusting member spanning the coupler and disconnected therewith, an uncoup1ingmem llo ber connected With the coupling pin, and an operating member capable of movements to operate both the adjusting and the coupling members.

In testimony whereof We have hereunto set our hands.
