UNCOUPLING DEVICE FOR CAR COUPLERS.

Application filed April Q1921. Serial iv-o. 458,501.

T all whom it may concern: v

Be it known that I GARTH G. GILIINV, a citizen of the United States, residing at River-side, in the county of Cook and State of Illinois have invented new and useful Improvements in Uncoupling Devices for Car Couplers, of-which thev following is a specification. a V v This invention relates to improvements in uncoupling devices for car couplers and more particularly to devices of this character employed on freight cars, and usually known as release rigging.

It isthe object of. this invention to.pro-" vide a simple and eflicient uncoupling de-. vice comprising but few parts and which can be readily attached to the different types of freight cars. i I

This particular invention relates to what is generally known in this art as the push down type of uncoupling device and comprises two levers having their adjacent ends pivotally mounted on the, same fulcrum. The particular advantage of this construction resides in the manner in which the levers are pivoted uponthe fulcrum. In levers of this general type mounted on a common fulcrum the connection between the levers must allow for the longitudinal movement of the coupler head in draft and inbufiing and the rotative movement of the pin lifting lever about the fulcrum must be limited for the purpose of safety to the operator.

The manner of mounting the levers on the fulcrum, in accordance with this invention, provides at the fulcrum means allowing play of the free end of the pin lifting lever in a horizontal plane without transmitting such movement to the hand lever, the connection between the levers surrounds the fulcrum and tilting of either lever from the vertical plane is prevented by positioning the levers between the shoulder on the fulcrum n1emher and lugs on the bearing and connecting block, or other similar projections on the fulcrum parts. This elimination of the tilting of the levers considerably reduces the friction between the levers and their fulcrum and safety stops preventing excessive rotating movement of either lever are also arranged at the fulcrum.

In the embodiment of this invention as illustrated the numerall indicates the end of a freight car ofthe non-end sill type, 2

the striking casting, 3 the couplerhead, t v the coupler locking pin eye, 5 the side sill and 6 the brake, mast, all of which are of usual construction. l

The uncoupling device comprises an operating lever 7 and a pin'lifting lever 8 having their adjacent ends mounted on a co1nmon fulcrum including a casting 9 mounted on a plate 10 depending from thejunderside of the car end. The pin lifting lever is provided with an offset to pass the brake mast with its free 'end portioi'i-parallel'to the car end, and is of reduced size, to pass through and beyond the eye of the looking pin with the extremity bent inthe form of a hook. Both ends of both levers are preferably offset, as shown so that their ex v tremiti-eswill lie in parallel horizontal planes which will allow the couplerhead to moveback and forth transversely with out transmitting its moven'ient to the pin lifting lever, provide a more convenient manner for attaching and mounting the ad ,jacent ends of the levers on the fulcrum and afford a ready hand grip or foot engagementon the. free end of the operating lever. i

'The fulcrum casting 9 comprises a base plate having a hollow bossll extending at right angles therefrom and is provided with a reduced cylindrical portion 12 at its outer end. Rectangular openings 13 are swedged in the adjacent ends of the operating and pin lifting leversthrough which is passed a rectangular connecting and bearing block 14 having a central aperture adapted to pass over and rotate upon the reduced por- This contheoutsidealong'its upper and lower edges with right angular lugs or projections 15 and the block is secured in position bya bolt 16 ssing typing the, rear throu glf the supporting plate 10 an'dlparts ll'and 12of the fulcrum casting having a Washer 1.7'a'ndnut l 0:1..thecout riencdhot they iul ru adap ecl Y to he en ged by the outer side ofthe hearing block.
