UNITED STATES PATENT OFFICE.

STERLING H. CAMPBELL, OF ST. LOUIS, MISSOURI.

To all whom it may concern:

Be it known that I, STERLING H, CAMP- BELL, a citizen of the United States of America residing at the city of St. Louis, State of Missouri, United States of America, have invented a certain new and useful Coupling-Release Ri ging, of which the following is such a fu 1, clear, and exact description as will enable any one skilled in the art to which it appertains to make and with my invention together with a portion of a railway car to which it is applied, Figure 1 is a top plan view, Fig. 2 is an enlarged end view of a portion of the device,

Fig. 3 is a front view of the parts shown in Fig. 2 and Fig. 4; is a front view of the parts shown in Fi 1.

5 indicates a railway car provided with.

a draw head 6 having the usual locking pin 7. In the locking pin 7 is a horizontal eye for engagement with the operating connection. .9 is a rock shaft forming the operating rod of the device and secured to the car 5 by means of

brackets

10 and 11, the bracket 10 being positioned adjacent to the handle end of the rod 9 and the bracket 11 at the opposite or inner end of said rod. 12 is the operating arm arranged at right angles to the rod 9 at the inner end thereof. 13 is the o erating handle carried atthe outer end of ti le rod 9 and arranged at right angles thereto and preferably at right angles to a plane passing through the arm 12. The outer end of, the operating arm 12 is provided with a horizontal eye 14:. 15 is a member forming the colfnection between the operating arm 12 and the locking pin 7. The

upper end 16 ofthe member 15 is bent over at right angles to the body of said member so as to form a pivot or trunnion passing through the horizontal opening 14 in the rod 12. The end 16 is threaded to engage with a nut 17 and is provided with a slot 18 so that after the nut 17 is in position the end of the member may be spread to prevent I Specification of Letters Patent.

the disengagement of said nut. The lower end of the member 15 is bent to form an enlarged loop 19 closed at both ends but having an opening 20 in the upper side to allow its en agement with the eye 8 of the locking pin In applying my device to a car the elon gated loop 19 is first engaged with the eye 8 of the locking pin which is accomplished by means of the opening 20, after which the end 16 is passed through the opening 14. The nut 17 is now placed in position and the end 16 spread by inserting any suitable tool in the slot 18. The elongated form of the loop will allow the necessary lateral movement between the operating rod 12 and the coupler head 6 while the rocking move ment in a vertical longitudinal plane will allow for the necessary longitudinal movement between the said parts. It will be noted that the arm 12 when in its normal position is slightly inclined upwardly as shown in Fig. 2 and that the handle 13 has a corresponding inclination to the perpendicular so that when the end rod of the arm 12 is drawn downwardly by the relative longitudinal movement between the rod and coupler while the train is in motion, the handle 13 will not be thrown into contact with the end of the car.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a device of the class described, the combination with a car having avertical plane coupler head provided with a locking pin, of a rock shaft carrying an integral operating arm provided with a horizontal eye formed in an integral portion of the arm, and a rigid connecting member pivoted in said eye to move only in a vertical plane in the direction of the length of the coupler, said member having an elongated open sided loop engaging with the eye of the coupler locking pin to allow lateral movement of the coupler head.

2. In a device of the class described, the combination with a car having a vertical plane coupler head provided with a locking pin, of a rock shaft carrying an integral operating arm provided with a horizontaleye formed in an integral portion of the arm, and a rigid connecting member comprising a vertical rod having a lateral projection at its upper end extending through said eye so as to move only in a vertical plane in the direction of the length of the coupler, an elongated loop at its lower end engaging with the eye of the coupler locking pin, and retaining means for said member carried by a 5 said proj ection.

3. In a device of the class described, the combination with a car having a vertical plane coupler head provided with a locking pin, of a rock shaft, an operating arm car- 10 ried by said rock shaft and normally inclined upward therefrom, an operating handle also carried by said rock shaft and normally inclined from the perpendicular, and a rigid connecting member having a fixed pivotal connection with said operating arm, and a laterally sliding connection with the coupler locking pin.

In testimony whereof, I have hereunto set my hand and affixed my seal.
