Divided and this application filed January a6, 1915. Serial No. ,flat-2l.

. at Riverside, in the county of Cook and #State et' illinois, have invented certain new and useful improvements in Uncoupling- Levers, of which the following is a specilication. L

(,)ne 'of the principal objects of the invention is to provide a device of novel construction in which a rigid link is utilized for lifting the locking' pin et the coupler, this link being directly connected with the locking pin and with the operating member ot the uncoupling device by connections which' allow the coupler perfect freedom in its normal intended movements, both lateral and longitudinal., and which furthermore permit an easy, free and unirnpeded ma nipulation of the device during the opera.- tion of raising the locking; pin.

A further object is 'to do away withl clevises, bolts, pins and other parts of like character which are apt to loe injured. or which may be lost when an uncoupling device connirising such parts is detached from the coupling for the purpose, for example, of repairing the latter and at the same time to provide an arrangement whereby the operative connection between the uncoupling` mechanism and the lock pin oi' the coupler is maintained under service conditions and also as against accident to and tampering; with the device. l

A further object is to provide a device of the general character' herein shown which will operate to automatically raise the locking pin upon an abnormal forward move-- ment of the coupler due to the failure of the coupler` or some of its connections.

A further object of the invention is to' provide an uncoupling device which will be very simple in its construction, economical to manufacture, strong, durable and reliable and effective in. its operation.

In the drawings: Figure l is a. fragmentary view in elevation ot the end oi a car with my improved uucoupling .leverl applied. Fig. il a side elevation of Fig, l. lig'. 3 is an enlarged detail trout elevation showing, ,in dotted lines, the coupler pin link in different positions to accommodate i Tthe lateral movement of the coupler. Fig.

d is an enlarged detail side elevation, also showing, in dotted lines, the coupling pin link in diderent positions to accommodate s the forward and rearward movement of the 1 draWba-r in draft' and bull. Figs. 5 and 6, are, views, at right angles to each other, et one form of pin links.

Rei'erencenumeral 9 designates the end .of a car (broken awayl, 10 the dead Wood,

and il the coupler resiliently mounted on the car, all of which may be ont any approved construction.

4The hand operated lever 12 is provided with acrank at each end at right-angles 'to each other, the crank 13, depending belov:l

the underface of the car, when vthe lever.

i "7o dle. lwith which to operate the lever 12 Wlule the crank 14, at the inner end of the.

is attached to the car and serving as al han lever, projects forwardly rornthe car to a. point ina plane perpendicular to the lock pin 15 of the coupler, an eye being formed on the end oli the crank 14e in ahorizontal-v plane. bymeans ot' the brackets 17 and i8 .each provided with lan opening through which the lever passes, said openings being of slightly greater diameter than the lever in order that the lever may have a slight play therein. yl`lie bracket 17 is provided with a stop 19 to limit the inward movement of the lever.' I n The connection between the lever l2 and the lock pin l5 oi' theconpler consists oi? a The lever l2 issecured to 'the car single rigid barlink 2O terminating in hooks' I 2l and` 22 at cach end disposed at right angles to each other, the end of the hook 21 being;` deflected to one sideas clearly shown in Figs. 2, 3, and G. It' will'be observed that the end of hook Z2 norinally stands close to the crank li so that the link can. bel turned or rotated with respect to itsv longitudinal axis to an appreciable extent only in one direct-ion. This permits the lower or deflected hook to be engaged with the lock pin when the apparatus is installed ontthe car, that is before the brackets are attached, and similarly the disengagement of the deflected hook .from the lock pin vprovided the operatingr rbd be dismountcd from the car. On the other hand with the rod in place onthe car there can be no other accidental disenbecause rotation in the opposite direction is necessary before arieh 'disengagement can be effected and this is prevented by the end of the hook 22 striking against the crank 14. 'lhe open hook 22 engages the eye 1G of the lever 12 and forms therewith a flexible joint between the lever and link, while the hook 21 engages the eye 15 of the lock pin and forms therewith a flexible joint. rThe upper end of the link 20 extends loosely through and projects beyond the eye 16 on the crank; the hook 22 providing means for retaining the link in the eye. The under surface of said eye provides a rounded bear- ;tor engagement with said eye 16 on the crank.

rl`he positioning of the flexible joint between the lever and the link in a plane perpendicular to the lock pin enables the link to travel with the coupler forward, under draft strains, and rearward under buff, without any binding or interlocking action between the link and lever, and also permits the link te move sidewise with-the late 'al movements of the coupler without binding or interlocking action between the lever and link; the joint between the lever and link being, in ellect, a universal joint.

in case of extreme forward travel of the draw bar in the event of its breaking or becoming loosened from its n orings, or in the event of the failure of the draft gear yoke or other parts of the draft gear, the link upon reaching the limit of its swinging movement withdraws the lock pin and permits the yknuckle of the coupler to open thus uncoupl'ing the two couplers and relieving the damaged draw bar from further pull and permitting it to remain in some of its bearings suspended' from the car, thus 'eliminating the danger incident to its dropping on the road bed.
