Abstract
Lubricating apparatus for the flanged wheels of railroad rolling stock comprises a lubricant applicator coupled to a source of lubricant under pressure. The applicator comprises a head engaging the wheel flange and coupled to a pivotally supported hollow shaft. A solenoid-operated, screw-driven piston working in a cylinder filled with lubricant supplies lubricant in metered amount to the hollow arm and thence to the applicator head, which spreads it in a uniform film on the flange of the wheel.
Claims15
In flanged wheel lubricating apparatus comprising a lubricant applicator unit adapted to discharge lubricant on the flange of the wheel, a lubricant drive unit providing a source of lubricant under pressure, and conduit means interconnecting the applicator and drive units, a lubricant drive unit comprising:
- a. a cylinder adapted to contain lubricant and having a port communicating with the conduit means and fitted with screw-driven piston means behind the lubricant,
- b. ratchet-driven gear wheel means arranged in driving connection to the screw of rhe screw-driven piston means, and
- c. electrically operated drive means arranged in driving connection to the ratchet of the ratchet-driven gear wheel means,
- d. the drive means comprising an electric circuit, an electric solenoid in the circuit fitted with a clapper and including crank means interconnecting the clapper and the ratchet of the ratchet-driven gear wheel means, and electric timing means in the circuit for energizing the solenoid at predetermined intervals.
In flanged wheel lubricating apparatus comprising a lubricant applicator unit adapted to discharge lubricant on the flange of the wheel, a lubricant drive unit providing a source of lubricant under pressure, and conduit means interconnecting the applicator and drive units, a lubricant drive unit comprising:
- a. a cylinder adapted to contain lubricant and having a port communicating with the conduit means and fitted with screw-driven piston means behind the lubricant,
- b. ratchet-driven gear wheel means arranged in driving connection to the screw of the screw-driven piston means, and
- c. electrically operated drive means arranged in driving connection to the ratchet of the ratchet-driven wheel means,
- d. the drive means comprising an electric circuit, an electric solenoid in the circuit, and electric timing means in the circuit for energizing the solenoid at predetermined intervals, the drive means being associated with the flanged wheel of a railway locomotive having a control for the locomotive drive, the electric circuit including a switch actuated by the locomotive control and operable to energize the timing means upon energization of the locomotive control.
In flanged wheel lubricating apparatus comprising a lubricant applicator unit adapted to discharge lubricant on the flange of the wheel, a lubricant drive unit providing a source of lubricant under pressure, and conduit means interconnecting the applicator unit and drive unit:
- a. a lubricant applicator unit comprising
- 1. an applicator head adapted to lie adjacent a flanged wheel, having a groove contoured to receive a wheel flange, and a channel opening out on the flange,
- 2. a shaft mounting the head on its forward end and having a longitudinal passageway communicating with the channel on one end and the conduit means on the other,
- 3. guide means receiving the shaft and restricting the latter to longitudinal sliding movement relative thereto,
- 4. resilient shaft-biasing means interengaging the guide means and shaft for biasing the shaft outwardly in the longitudinal direction, and
- 5. stop means associated with the biasing means for limiting the longitudinal movement of the shaft under the applied bias of the biasing means;
- and
- b. a lubricant drive unit comprising
- 1. a cylinder adapted to contain lubricant and having a port communicating with the conduit means and fitted with screw-driven piston means behind the lubricant,
- 2. ratchet-driven gear wheel means arranged in driving connection to the screw of the screw-driven piston means, and
- 3. electrically operated drive means arranged in driving connection to the ratchet of the ratchet-driven gear wheel means,
- 4. the drive means comprising an electric circuit, an electric solenoid in the circuit, and electric timing means in the circuit for energizing the solenoid at predetermined intervals, the drive means being associated with the flanged wheel of a railway locomotive having a control for the locomotive drive, the electric circuit including a switch actuated by the locomotive control and operable to energize the timing means upon energization of the locomotive control.
