Definitions

  • This invention relates to train braking systems, the chief object being to provide for the stopping of a train in a simple, eliicient and expeditious manner upon derailment of the train or a part thereof.
  • the train pipe of the braking system has associated therewith trip means adapted to permit communication between the train pipe and the atmosphere to cause a braking effect to be obtained upon derailment of the train or a part there of.
  • the said trip means may comprise, for instance, a suspended pipe or pipes connected to and in communication with the train pipe of the braking system, which may be of the vacuum, or ld estinghouse, or other type, the said pipe or pipes being adapted upon derailment of the train, or a part thereof, to permit air to enter, or escape from, the train pipe, according to the type of braking system empl yed, and thus cause braking to be effected in known manner, derailment being notified simultaneously, if desired, to the driver, for instance, of the train by the indication on the vacuum gauge on the engine.
  • the trip means would normally be so disposed as to engage with the rails, or the ground, or track, as soon as derailment takes place.
  • Figure l is a side elevation showing apparatus embodying the invention applied to the under-frame of a railway vehicle, the said under-frame being illustrated diagrammatically by dotted lines for the sake of clearness,
  • Figure 2 is a plan view
  • Figure 3 is a tranverse sectional view taken approximately on the line 3-3, Figure 2-,
  • Figure 4 is a fragmentary sectional view, on an enlarged scale, showing the trip means and relative parts, the trip means being in inoperative position, t
  • Figure 5 is a plan view thereof
  • Figure 6 is a view similar to Figure 4 but showing the trip means in operative position.
  • 1 denotes in general the under-frame of a railway vehicle and 2 a train pipe secured thereto, the train pipe having connected thereto and in communication therewith suspended pipes 3 spaced longitudinally from'one another and disposed one at each side of'the longitudinal centre of the vehicle, the train pipe being suitably arranged for this purpose, as shown more particularly in Figure 2.
  • Each of the suspended pipes 3 is shaped at the lower part thereof so as to afford a metallic flanged portion 4 disposed substantially horizontally and having an opening in communication with the train pipe.
  • the said flanged portion is provided, as shown in detail in Figures a and 6, with a facing 5 having a rubber or other resilient washer 6 arranged in an annular recess 7' and adapted to be engaged normally preferably by a corresponding washer 8 in an annular recess 9 in the facing 9 of a metallic closure 10 pivotally mounted at 11 relatively to the said flanged portion 4-.
  • the said closure has associated therewith an overhanging extension 12 which is bent or projected downwardly in such a manner that the outer end or extremity thereof, which is shown with oppositely directed oif-set portions 13 affording an extended contact surface, will occupy normally a convenient position, for instance, above one of the rails 14, so that in the event of derailment, the said extension may co-operate with the rail, or track, and cause the said pivoted closure to be actuated so as to occupy the position shown in Figure 6 and permit communication between the train pipe and the atmosphere, with a consequent braking ofthe train.
  • the co-operating washers 6 and 8 project or flare outwardly, thus ensuring a more effective oint between the closure 10 and the flanged portion 4 of the suspended pipe 3 when in normal engagement with one another.
  • the trip devices are arranged so as to provide for derailment taking place at either side of the train.
  • a train braking system comprising a train pipe, a suspended pipe carried by said train pipe, a pivoted closing member for said suspended pipe, said closing member being provided with jointing washers adapted to project outwardly upon the tripping of said pivoted closing member.
  • a train braking system comprising a train air pipe, pipes suspended at intervals and connected to said train pipe, pivoted closing members on the free ends of said suspended pipes, and means for trip ing said closing members to open the ends of said suspended pipes and form communication between the atmosphere and the train air pipe.
  • a train braking system comprising a train air pipe, pipes suspended at intervals and connected to said train pipe, a flanged portion formed with an ear secured to the free end of each of said suspended pipes, a closure member pivoted to said ear and adapted to close the free ends of each oi. the suspended pipes, sealing means between the flanged portion and the closure member, and means for trippingsaid closure member.
  • a train braking system comprising a train air pipe, pipe suspended at intervals and connected to said train pipe, a flanged portion formed with an ear secured to the free end of each of said suspended pipes, a closure member pivoted to said ear and adapted to close the free ends of each of the iuspended pipes, cooperating gasket members carried on said flanged portion and said closure member to efl'ectually seal the ends of said suspended pipes, and means normally holding said closure member in tight relation to said flanged portion, said means serving to trip said closure member on derailment of the car.
  • a train braking system comprising a train air pipe, pipes suspended at intervals and connected to said train pipe, a flanged portion formed with an ear secured to the free end of each of said suspended pipes, a closure member pivoted to said ear and adapted to close the free ends of each of the suspended pipes, sealing means between the flanged portion and the closure member, and an arm secured to and extending from said closure member normally serving, to hold said closure member in tight relation with said flanged portion, said arm engaging the rail and opening said closure member on derailment of the car.
