Definitions

  • Such appliances are generally mounted upon the outer rail of the track at a curve for thepurpose of greasing the .inner face of the outer rail as it iswell known that by such grease application economy in engine power consumption and reductionin tyre flange and rail wear is brought about.
  • a further object of the invention is to provide means whereby the quantity of grease or other lubricant discharged at each operation can be effectively controlled and in which the appliance can be easily adjusted by a relatively unskilled workman to vary the grease output.
  • Figure l is a front elevation of the grease container without pumps attached.
  • Figure 2 is a part sectional side elevation of the same.
  • Figure 3 is a side elevation on an enlarged
  • the lubricating device comprises a cylindrical grease container I having one end closed with a removable cover '2 which forms the abutment for the thrust of a spring 3, the free end of which urges forward the sliding piston 4 which pushes forward the grease G with a light pressure, for instance, a pound or so per square inch, which is suilicient to propel it through the duets 6 to the outlet or communicating ports '5.
  • a light pressure for instance, a pound or so per square inch
  • the lugs 5 also serve for the attachment of 5 bolts H which pass through the rail web, and hold the grease container to the outside, and the greasing plate to the running face of the rail.
  • the faces of the lugs in which the ports l are 1 formed have smooth and preferably fiat ends for the attachment of pumps [2 which preferably are in the form of angular blocks of metal of substantial construction, each of which is fitted with plungers [3, with itsaxis substantially ver- 1 tical, and with .its head projecting above the
  • the plunger i3 is provided with a flange or stop I4 to limit its upward movement, and to receive the thrust of spring l5.
  • This barrel is preferably removable, and the top or a shoulder formed atso-me part of its length serves as a thrust or support for spring [5.
  • the lower end of hole IT is preferably provided with a simple ball valve l8 held up by a light spring l9.
  • the pumps 12 are adjustably held against the vertical facings of lugs by one or more bolts 26 passing through slotted holes 21 and Within the limit of adjustment, inlet port 25 in pump I2 is always open to duct outlet 1, and delivery hole 23 is open to duct 24 On the main casting 5.
  • the purpose of this adjustment is twofold, firstly, the height by which the external end of plunger l3 extends above the tread of passing wheels, determines the stroke and displacement of the pump, and this is increased by raising the pump 12 and decreased by lowering.
  • the rails towhich the lubricators are fixed may have their upper surface more or less worn down, and the adjustable feature of the pump permits of the apparatus being fixed to such rails and correctly set without altering the main casting, and particularly the bearing points it previously referred to.
  • the fastening bolts ll preferably two in numher, and one to each lug 5 may pass through a hole in 5 and be screwed into the anchorage strip 29 which is placed against the web of the rail on the running side, but preferably the arrangement is reversed and use is made of a bolt having a somewhat longer head than the ordinary bolts of commerce, and under the hexagon head 30 is formed a circular collar 3
  • the small diameter part of bolt II is passed through the metal bar 29 which is substantially the same length as the greasing plate 32 and through a hole drilled through the neutral axis of the rail, and screwed into a hole 33 tapped in lug 5.
  • This hole is prolonged beyond the end of bolt I I and forms a cavity into which grease discharged into duct 24 as previously described passes via hole 34 into hole 35 in bolt H thence through cross hole or holes 36 into space 31 around collar part 3! of bolt, thence into longitudinal channel 38 and vertical channels 39 into space 49 between top of anchor piece or bar 29 and underside of rail head from whence it passes through a plurality of vertical channels 4
  • the space 31 mentioned above is caused by making the hole in the greasing plate 32 considerably larger than collar 3
  • cover strip 43 On the outside of plate 32 is a cover strip 43 which is used to seal effectively holes 31A (Figure 5A) against the escape of grease around bolts or screws 1 IA which hold plate 32 against anchor plate 29 at positions other than those occupied by bolts II.
  • a cap 44 is provided for each bolt, and this cap, when forced against strip 43 by bolt 45, not only prevents escape of grease, but helps to hold plate 32 against plate 29 and the rail face.
  • the greasing plate 32 may be adjusted or removed without disturbing the attachment of the anchor plate 29 and grease cylinder l to the rail.
  • An automatic rail lubricator for supplying grease to the rail face comprising a plunger type of grease pump actuated directly by the tread of a vehicle wheel passing over the rail, a grease container having means for its attachment to the rail and carrying said pump, means for supplying grease from said container to said pump under pressure and a greasing plate for distributing grease delivered by said pump over the rail face, said pump being adjustably mounted upon said container to permit of said pump being raised or lowered to increase or decrease its effective stroke and thereby vary the quantity of grease supplied to the rail face and also to compensate for wear of the rail head, said pump being in the form of a self contained unit bolted in position upon a lug associated with said grease container, the pump casing having ports adapted to register with ports in the lug communicating with the grease container, said ports in said lug being larger than said ports in said pump casing to ensure registration in any position into which said pump may be moved for adjustment purposes.

  • An automatic rail lubricator for applying grease to the rail face comprising a lubricant container having means for its attachment to the rail, a plunger type grease pump actuated directly by the wheel tread and comprising a selfcontained unit adjustably mounted on the lubricant container external thereto, means for supplying lubricant from said container to the pump under pressure and a greasing plate for distributing lubricant delivered by the pump over the rail face.
  • An automatic rail lubricator for applying lubricant to the rail face comprising a lubricant container having means for attachment to the rail, a plunger type pump comprising a complete pump'unit adjustably mounted on the lubricant container external thereto, means for supplying lubricant from the container to the pump under pressure, a fixed greasing plate for distributing lubricant deliveredby the pump over the rail face, and a non-return valve device associated with the pump for segregating the pump from the greasing plate after each supply of lubricant has been delivered thereto.
