Third-rail Shoe Patents (Class 191/49)
  • Patent number: 11938829
    Abstract: A third rail paddle system includes a support assembly configured for attachment to a vehicle, a pivot connection attached to the support assembly and that defines a range of up and down movement, and a third rail paddle assembly having an arm unit and a paddle. The paddle assembly is attached to the pivot connection for the paddle to contact a third rail and move up and down relative to the third rail when the support assembly is attached to the vehicle. One of the pivot connection, the paddle assembly, or the support assembly includes a stop element that limits the range of the up and down movement and prevents the paddle assembly from moving downwards to a bottom of the range of movement.

  • Patent number: 9834095
    Abstract: In an apparatus and method of automatically providing or withholding fluid from a power rail for a mass transit vehicle, during movement of a mass transit vehicle on a pathway in an uncovered (or exposed) area of the pathway, fluid, for example, anti-icing fluid, is caused to be provided to (or dispensed on) the power rail supplying power to the mass transit vehicle. During movement of the mass transit vehicle in a covered area of the pathway, the fluid is withheld from (or not dispensed on) the power rail. The changing from fluid being dispensed on the power rail to the fluid being withheld from the power rail, or vice versa, can be based on movement of the mass transit vehicle from the uncovered area of the pathway to the covered area of the pathway, or vice versa.

The grounding pad is attached to a second end of the member. The grounding pad may be attached to the member in any location suitable for collecting ground from the guide beam during use. A pair of lock-on devices is installed on the vehicle, such that one is located on each side of the guide beam. Since the lock-on device is attached to the guide frame of the vehicle and engages the underneath of the guide beam, any force tending to tip the vehicle will cause the lock-on device to “grab” the guide beam. The relationship of the guide beam and the grounding pad prevents the vehicle from tipping. Thus, track jumping and roll over are inhibited.

    Abstract: The present invention is a third rail assembly that includes a beam made of synthetic material which will not crack upon exposure to the elements so that conductive material such as water, grease, or the like will not settle in the cracks. Also, the beam is lightweight for ease of installation and very strong so that the beam will not be destroyed when the third rail collector encounters an obstacle.

  • Patent number: 5193656
    Abstract: A collector shoe for a collector with a carbon brush and a support has, between the carbon brush and supporting element, a galvanically applied metallic layer. The galvanic layer anchors a head portion of a conductor member to the carbon brush. The conductor member has a shaft portion which projects through the support and secures the carbon brush to the support, as well as, establishes an electrical connection to the carbon brush.

  • Patent number: 5152380
    Abstract: A collector shoe for a collector with a carbon brush and a support has, between the carbon brush and supporting element, a galvanically applied metallic layer, which, at least at one end, either extends itself over the carbon brush at an angle, its extension which forms an angle being at least partially molded onto the supporting element or embedded into the latter and designed as an electrical connection element, or is linked with an electrical element which extends beyond the carbon brush, forms an angle and is similarly molded onto the supporting element or embedded in the latter. An advantageous process for producing said collector shoe consists producing the carbon brush with excess length, covering it in the metallic layer and then cutting it to length, and consequently bending the projecting metallic layer into the angular shape and embedding it in the directly molded-on supporting element of synthetic material.

  • Patent number: 4723641
    Abstract: A collector shoe assembly for transmitting current from an electrified rail to a mobile unit such as a trolley, crane, conveyor, or the like. In a preferred embodiment the electrical collector comprises an electrically conductive shoe for slidably engaging an electrified rail, and a bracket assembly to support and guide the shoe along the rail. The bracket assembly comprises a parallel pair of pivotally supported brackets with a transversely extending support and pivot pin extending between the outer ends. Supported on the pin between the brackets is the shoe which includes a U-shape top channel adapted to receive the pin. The pin is loosely captured within the channel by a pair of readily removable bolt and washer assemblies which are threadedly secured into the top of the shoe.

  • Patent number: 4572929
    Abstract: An assembly for the transmission of electrical energy to a vehicle comprises two current rails with respective contact surfaces inclined at an angle toward each other in a roof-like arrangement and a current collector having a sliding shoe with a pair of contact surfaces inclined toward each other at the same angle. The sliding shoe is mounted movably on the current collector by means of a ball and socket joint. The support point of the sliding shoe, i.e. the geometrical center of the support ball, is located at least approximately on an imaginary line which connects the centers of gravity of the two contact surfaces of the current rails.

  • Patent number: 4324301
    Abstract: A bumper car amusement ride includes a floor to which is adhesively bonded over their entire under surfaces a plurality of elongated electrically conductive plates separated by electrically non-conductive strips and with adjacent plates connected across a source of alternating current. A bumper car is supported for movement over the plates and strips by a pair of laterally spaced drive wheels and a pair of longitudinally spaced caster wheels, each of the drive wheels being coupled to the reversible, variable speed output of a hydrostatic transmission, the inputs of which are both coupled to the output of a direct current constant speed electric motor. The motor is connected through a rectifier to a plurality of contacts mounted on the car for sliding engagement with the floor plates.

  • Patent number: 4286698
    Abstract: A sliding contact for a toy rail vehicle has a body part having a convex slide face and a depression which is provided in the convex slide face and arranged so as to form on the latter an edge by which said slide face linearly contacts with a current-conductive rail and which removes extraneous particles from the current-conductive rail during sliding over the latter. The depression may have a circular cross-section so that the edge formed by the depression is annular. The depression may have a diameter which exceeds the width of the rail so that two curved edges are formed one of which is a leading edge, whereas the other of which is a trailing edge.
