Definitions

  • My present invention relates to bumpers for railway vehicles and it has for its object to provide another embodiment of the generic invention disclosed in my application filed March '7, 1936, Ser. No. 67,715, issued as Pat. No. 2,187,625 of which the present application is a division.
  • the present invention provides two or more buffers disposed on either side of the longitudinal axis of the vehicle, the buffers being rigidly connected with two or more pistons, respectively, movable in corresponding cylinders which contain, at one side of the pistons, a compressible fluid, the cylinder for a piston at one side being 50 connected with the cylinder for a piston for the other side as to effect communication between the compressible fluid sides of the cylinders whereby the compressible fluid from a cylinder at one side of the vehicle will flow to the cylinder at the other side, and vice versa, according to the respective movements of the pistons, there being a third cylinder provided in comcunication with such connection, the third cylinder containing a piston connected to a drag hook through which two adjacent cars are coupled together, the piston in the third cylinder being subject, at one side, to the influence of the air in the other two cylinders when both their pistons move inwardly together, and being subjected at the other side to an air spring.
  • Fig. 2 is a diagrammatic view illustrating the working of the system according to the invention.
  • I and 2 represent two railway vehicles, each of which has a fixed cylinder 3 located at each side of the axis of the vehicle.
  • the cylinders 3 of one vehicle align, respectively, with those of the opposing vehicle.
  • each cylinder 3 Within each cylinder 3 is a piston 4 whose rigid rod carries a buffer 1.
  • Each cylinder encloses a chamber 5 containing a compressible fluid under above-atmospheric Serial No.
  • Each cylinder also contains a chamber 6 containing air.
  • the chambers 5 are at the rear sides of the pistons, while the chambers 6 are at the fore side thereof.
  • a third cylinder l2 communicates at one end through ducts 9 with the chambers 5 of the respective cylinders 3.
  • the other end of the cylinder I2 is closed.
  • Within the cylinder I2 is a piston l3 connected directly to the drag hock I5 by which two adjacent cars are coupled together, the drag hook I5 having its rod portion passed through a suitable gland M.
  • the piston I3 is suitably packed so thatwhen it is forced inwardly it will compress the fluid in the cylinder I2 between the piston 13 and the closed end of the cylinder, which fluid then acts as an airspring or cushion.
  • piston 13 is given an area substantially equal to the sum of the areas of the two pistons 4-4, the displacement of the drag hook I5 is made equal to that of the two pistons 4-4, so that the coupling shall be given a uniform tension.
  • Fluid may be introduced into the cylinders 3 through a small inlet tube l0 provided for connection with a high pressure pump. Eventually, the discharge of the fluid may take place through this tube l0.
  • the tube It] is of course suitably capped.
  • At least tWo bufiers movably carried by said vehicle on either side of the longitudinal axis thereof, two cylinders rigidly carried by said vehicle, pistons movable in said cylinders with a fiuidtight fit and rigid with said bufiers, respectively, a third cylinder, a piston movable with a fluidtight fit in said third cylinder, passages for interconnecting both of the first mentioned cylinders at their rear ends and the third mentioned cylinder at its front end, a compressible fluid filling the whole of these passages and the 10 two first mentioned cylinders.
