IRELEASE-RIGGING.
Specification of Letters Patent.
PatentedMay 5, 1914.
Application filed December 27, 1913. Serial No. 809,032.
To aZZ whom it may camera:
Be it known that I, WALTER P. MURPHY, a citizen of the United States, residing at Chicago, State of 11 inois, have invented certain new and useful mprovements in Release-Rigging, of which the following is a specification.
The object of my invention is to produce a release rigging which may be operated either by a movement in a vertical plane or a movement in an arc, and it cons sts of a rock shaft flexibly connected at its inner end with the locking pin of a car coupler, and provided intermediate its ends with a crank to which an operating handle is pivotally interlocked intermediate its ends, the lower end of the handle terminating in a crank beneaththe plane of. the underface of the car while the other end is movably anchored to the car; and my invention consists, fur- 'ther-in'the parts and combination of parts as will be more fully hereinafter pointed out.
In the drawings: Figure 1 is a top plan view of a car (broken away) with my improved release rigging attached thereto. Fig. 2 is an end elevation of Fig. 1'. Fig. 3 is a detail perspective view. Fig. 4 is a detail view of another embodiment of my invention.
The reference numeral 1 designates a car,
i 2 and 3 brackets secured to the end of the car and 4 a rock shaft journaledin said brackets, the inner end of the shaft terminating in a forwardly extending crank' 5 which is flexibly connected with the locking pin of a car coupler. The rock shaft 4 is provided intermediate its ends with a crank or lever 6 with which an operating handle 7 has an interlocking pivotal joint intermediate its ends, the lower end of said handle terminating in an outwardly extending handle 8 which is positioned in a plane below the plane of the underface of the car in order that it may be readily operated by the foot or hand of the operator. The upper end of the handle projects beyond the inter locked pivotal joint of the lever 6, and haildle and is movably' anchored to the car, preferably, in the bracket 2 which is provided with a runway 9 into which said upper end projects, whereby the handle has a connection with the rock shaft and with the car body. This runway is such that it does not interfere with the movement of the handle with the lever 6.
In Fig. 4 I have shown the lever 10 on the rock shaft 11 as consisting of an eye which is inclined at approximately 20 degrees to the longitudinal axes of the rock shaft. 12 is an operating handle having intermediate its ends an interlocking pivotal joint with the lever 10, the body of the handle passing through the eye and terminating at its lower end in a crank 13 while the upper end portion of the operating handle projects beyond the lever 10 and its extreme end'is loosely anchored in the bracket 14, as explained in connection with Figs. 1, 2 and 3.
Referring to Figs. 1, 2, and 3 the operation is as follows: The parts being in a normal position the brakeman standing on the usual sidestep of a car places one foot on the crank 8 and pushes downward in a vertical plane, thus pulling the crank or lever 6 downward thereby revolving the rock shaft and operating the locking pin, the runway in the bracket permitting of the upper end of the handle to move and at the same time maintaining the interlocked relation between the lever 6 and the operating handle. If the brakeman should be standby pulling the crank 8 forward in an are thus bringing the body of the handle against the rock shaft 4: which serves as a fulcrum 'ing beside the car, he may operate the device for the handle wherebytherock shaft is rotated and the locking pm operated. In this movement the operating handle acts as a le-' vcr of the first order. I
The operation of the other construction is practically the same as just described The lower portion of the eye serving as a fulcrum for the operating handle when said handle is moved to serve as a lever of the first order.
What I claim is:
- 1. In a release rigging for a car coupler, the combination with a rock shaft journaled in brackets secured to the end of a car, and flexiblyconnected at its innerend with the locking pin of the coupler, a lever on said rock shaft substantially at the ends thereof, an operating handle having intermediate its ends an interlocking pivotal joint with said lever, the lower portion of said handle terminating in a crank positioned in a plane below the plane of the underface of the car,
2. In a release rigging for a car coupler, low the plane of the underface of the car the combination with a rock shaft journaled while the upper end portion of the handle in brackets secured to the end of a car, and projects beyond the lever of the rock shaft flexibly connected at its inner end with the and looselyengaging one of said brackets.
