  • Patent number: 8307955
    Abstract: A hand brake mechanism having a mechanism to disengage a release lever disposed within a clutch and release assembly at the beginning of the brake application cycle. This mechanism includes a holding pawl having a force transmitting member which cooperates with a force receiving member disposed within the release lever to effect rotational motion onto the release lever at the beginning of the brake application cycle. At least one spring is provided to substantially complete rotational motion of the release lever.

  • Patent number: 7467724
    Abstract: A locking arrangement for securing a bearing assembly to a male connection member of an articulated coupling apparatus includes an aperture having an outwardly extending beveled portion formed at each end thereof. A race assembly of the bearing assembly has a beveled portion abuttingly engaging a first beveled portion of the aperture and has an inwardly extending recessed portion and a ledge portion disposed adjacent the second beveled portion. The ledge portion at least partially closes the recessed portion and has an inner surface extending from the recessed portion towards the aperture at a predetermined angle. A locking member is disposed in a groove formed by such second beveled portion, the recessed portion and the inner surface of the ledge portion for securing the race assembly within the aperture in combination with the opposed beveled portion formed in the race assembly.

  • Patent number: 7467812
    Abstract: An apparatus for lifting a brake hose including a glad hand secured to one end thereof. The brake hose to be lifted into an elevated position is attached to an end of a railway car. Such apparatus further maintains the brake hose in such elevated position during in track service. Such apparatus includes a first member engageable with a predetermined portion of such railway car and a second member engageable with one of such glad hand and such brake hose. There is at least one fluid pressure actuated expansion member disposed between and engageable with such first and second member. Additionally, a supply line having a choke is disposed in fluid communication with such at least one fluid pressure actuated expansion member and a source of fluid pressure for expanding the expansion member in a longitudinal direction and thereby raise such brake hoses to a predetermined elevated position.

  • Patent number: 6902042
    Abstract: An automatic application hand brake mechanism is provided for automatically applying at least one brake member secured to a railway vehicle with the hand brake assembly. The mechanism comprises an operating member having at least one ratchet engageable with at least one gear of the hand brake assembly for operating the gear assembly in a direction which will cause an application of the at least one brake member. The apparatus also includes an application cylinder and a drive arm extending from an end thereof having a first portion which is connected to the operating member. The drive arm is capable of reciprocating with respect to the application cylinder upon the application of a force thereto to supply a predetermined pressure to the operating member to cause an automatic application of the at least one brake member.

  • Publication number: 20050039993
    Abstract: An apparatus engageable with a hand brake assembly for automatically applying at least one brake device secured to a railway vehicle with such hand brake assembly. The apparatus includes an operating mechanism having at least a portion thereof engageable with at least one gear of a gear assembly disposed in a housing member of the hand brake assembly for operating such gear assembly in a direction which will cause an application of such brake device. A source of fluid pressure is connected to the operating mechanism for periodically supplying a predetermined pressure to such operating mechanism for the application of the brake device. An activating device is connected to the source of fluid pressure for initiating the supply of such predetermined pressure to the operating mechanism thereby causing an automatic application of such brake device by the hand brake assembly.
