RELEASE-RIGGIN G.

Application filed. September 24, 1909; Serial No. 519,471.

To'alZ whom it may concern:

Be it known that 1, Human P. MURPHY, a citizen of the United States, and resident of St. Louis, State of Missouri, have invented a release rigging that is practical and can be applied to cabooses, tenders, etc., thathave no dcadwoods, as well as to cars w1th deadwoods; and with this and minor objectsin view my invention consists of the parts and combination of parts as will be more fully hereinafter set out.

In the drawing, Figure l is a top plan view of a car end sill and coupler, parts being broken away, with my improved rigging in position; Fig. 2 is a front elevation of the same; Fig. 3 is a detail view of the pin op erating lever and its mounting; Fig. 4 is a front elevation with the locking pin and locking pin lever in elevated position and the hand lever in normal position; Figs. 5

= and 6 are detail views showing different bends in the inner end of the hand lever.

represents the end sill of a car which may be of any approved pattern and may or may not have a deadwood, as far as the practicability of my invention is concerned.

- 2 are suitable bearings secured in any suitable manner to the end sill, in which is loosely journaled the hand operated rod or lever 3, the outer end of which terminates in a handle 4, which extends below the underface of the end sill as shown in Fig. 2. The inner end of the lever 3 terminates in a crank 5 extending horizontally when the lever 3 is in operative position on the end sill and is at a right. angle to the handle 4. 6 is an eye formed on the extreme end of the crank 5, the body forming the eye,,being formed in the longitudinal'axls of'the.

crank while the opening therethrough extends inthe vertical or transverse axis.

The pin operating lever 7 is tapered along its main body toward its inner end to adapt it to pass through the eye 8 of the usual lockin pin and is of such diameter that the eye 8 may slide freely thereon with minimum friction. The extreme inner end .of the lever 7 is bent to form a hook 9, which prevents the lever from becoming accidentally disengaged from the eye 8. The outer end of the pin lifting lever is bent to form a shoulder 11 and still further bent to form a hook Specification of Letters Patent.

12, by means of which'the pin lever 7 is secured to the crank 5 by reason of its ongagement with the eye 6; the engagement of one side of the hook 12 with the shoulder 11 and the engagement of the hook 12 with the other side of the eye serves to hold or support the pin lever 7 in a horizontal position normally, as shown in Fig. 2. The two levers may be entirely of'commercial bar wrought iron, which is a material consideration from the standpoint of durability and manufacture. This improved release rigging allows the coupler to move in and out sidewise and yet after the locking pin has been raised for lock setting, the handle 4 will drop to its normal vertical position,

while the pin lifting lever remains elevatedwith the pin.

The rod or lever 8 is revolved by means of the handle, which in turn elevates the crank 5, which through the hook 10 and eyefi elevates the pin'lifting lever 7, thereby lifting the locking pin for lock setting or throwing open the knuckle full open. As soon is the operator releases the handle 4-, the rod or.

lever 3 revolves under the weight of the handle, whereby the handle will drop and assume its normal" ver ical position against the face of the end sil thus eliminating all danger and damage resulting from the EIS E handle being struck by an abutting car.

The joint formed by the eye 6 and hook 12 is, for all practical purposes, substantially a universal jointwhich permits the lever 7 toremain in its elevated position, while the locking pin isheld 1n 1ts elevated position rigging; may be used on cabooses that must be uncoupled by a chain to hand rail and yet comply with the safety appliance law by being operative outside the rails.

The pin lever 7 is free to move backward,

forward and upward independent of any for lock setting, eta, and at the same time permits the handle4 to return to and re final 11 111 its normal vertical position. This lever 3. In Fig. 5, the bend is at a right angle to the main body of the lever. .In this construction, the outer end of the pin lever shown in dotted lines is formed in an eye,

shown in section. Should the draw bar pull a joint which will permit the crank to return to normal position after operating the pin lever without moving the pin lifting lever from its abnormal position.

Copies of this patent may be obtained for five cents each, by addressing the 60 Washington, D. 0.

2. A release rigging including a hand operated lever having a depending handle at its outer end and a forwardly extending crank at its inner end, the'crank havin Ian eye formed at its inner end, a pin li tin lever having an open hook at its outer end to engage the eye of the said crank, whereby .the pin lifting lever may be elevated, and

remain in such'elevated position while the crank and handle of the hand lever are free to return to their normal position.

In testimony whereof I afiix my signature in presence of two witnesses.
