| 70 | Uncoupling Lever For Rail Car With Biasing Member | US15475372 | 2017-03-31 | US20180281827A1 | 2018-10-04 | Brian Maki |
| An uncoupling lever for a railcar has first, second, and third lever members slidably connected to each other for relative motion along their lengths. The second and third lever members are urged apart from one another along their lengths with a biasing member. The uncoupling lever has a handle configured for manual operation of the uncoupling lever, and a hook configured for actuating a lock of a coupler of the railcar. One of the handle and hook is operatively connected to the first lever member and the other of the handle and hook is operatively connected to the third lever member. | ||||||

| A spring-style railway hose support has a retraction-biased extension unit of a longitudinally compressible spring and a pair of oppositely directed internal wireforms within the longitudinally compressible spring. The internal wireforms engage respective ends of the longitudinally compressible spring, and a closed end of each is configured to allow it to project beyond a respective end of the longitudinally compressible spring. The retraction-biased extension unit is adapted to be directly or indirectly connected to a railway brake hose and to a railway car component that is positioned above the hose on a railway car. | ||||||

| A lower lockpin rotation shaft assembly includes a lower lockpin rotation shaft body, an outer end portion thereof having a first coupler lifting bar hole, an intermediate portion thereof having a connecting key; and a lower lockpin rotation shaft bush, an outer end portion of the lower lockpin rotation shaft bush having a second coupler lifting bar hole, and an inner end portion of the lower lockpin rotation shaft bush being operatively connected to an inner end portion of the lower lockpin rotation shaft body. Further, the present invention further provides a double-side operating coupler and a coupler draft gear having the above lower lockpin rotation shaft assembly. The coupler draft gear further includes two coupler lifting bars and two coupler lifting bar seats. Each of the coupler lifting bars is inserted in a keyhole-shaped through hole of corresponding coupler lifting bar seat, and the coupler lifting bar has a restrained segment at a fitted portion of the coupler lifting bar with the coupler lifting bar seat. Coupler heads of the two coupler lifting bar are inserted through the keyhole-shaped through holes of the two coupler lifting bar seats and then coupled with the first coupler lifting bar hole and the second coupler lifting bar hole of the double-side operating coupler. There is a gap between the restrained segment of each coupler lifting bar and walls of the rectangular hole of the keyhole-shaped through hole. | ||||||

| A telescoping, uncoupling lever for a railroad car. The lever is formed of round rod and includes a handle rod, a lock lifter rod and a track assembly. The track assembly includes a handle rod track and a lock lifter rod track with tracks connected to each other at their opposite ends. A glide housing is attached to one end of the handle and lock lifter rods to allow the handle and lock lifter rods to slide on the tracks of the track assembly. Each glide housing is tubular, has a cavity extending there through to connect rod openings at the opposite ends and has glide of C-shaped transverse cross-section positioned therein to receive and partially encircle a rod. | ||||||

| Removing the draft key from a so-called E-type railway car coupler can be a difficult job. A relatively simple tool for removing a key of the type including a flanged head includes a pair of parallel hydraulic cylinders, a yoke interconnecting one end of the cylinders, piston rods extending out of the other end of the cylinders, a sleeve in the yoke parallel to the cylinders, an elongated shaft for removable mounting in the sleeve, a latch for retaining the shaft in the sleeve, and a socket in the outer free end of the shaft for receiving the head of the key, whereby with the shaft in the sleeve and connected to a key, extension of the piston rods against the coupler pocket pushes the cylinders, and consequently the sleeve and shaft outwardly to pull the key from the coupler. | ||||||

| An apparatus for rotating a bearing assembly secured in an aperture at one end of a male connection member is provided. This apparatus includes an L-shaped member one leg of which engages a first surface formed on a longitudinal portion of a shaft member of such bearing assembly and a second leg which during use will be aligned with a bore formed in such outer end of the shaft member. A nut-like member is secured to an outer surface of such second leg which can be engaged by a tool capable of applying a force thereto for rotating such bearing assembly. Such nut-like member has a cavity formed therein adjacent an outer surface thereof. Such apparaus further includes a device for securing such apparatus to such bearing assembly in a removable manner. | ||||||

| A lifting device powered by an impact wrench, specifically designed to raise a on car railway freight car coupler. The embodiment of the invention disclosed herein comprises:A base plate that houses a load bearing that a lifting screw rod fits into and rotates on. A top plate that houses a pilot bearing that the screw rod passes through and is held vertical by, thereby stabilizing load being lifted. Four stachion rods that connect the top and bottom plates forming the coupler lift body.A lifting block with carrying handle that threads onto the screw rod with an attached arm that engages the freight car coupler. The lifting block is powered up and down the screw rod by applying an impact wrench to the attached socket at top of same. | ||||||

| An uncoupling rod assembly for railway vehicles having cushioning incorporated therein. The assembly includes telescoping members to accommodate the length of travel and swinging movement of the couplers. The telescoping members are formed from relatively thin stock to reduce the weight of the uncoupling rod assembly.
