Definitions

  • the present invention relates to braking and stopping devices intended to slow down and stop vehicles which run on rails.
  • a known device comprises a wedge-shaped body, one of the opposite sides of which rests on the upper rolling face of the rail and the other side of which is intended to come into contact with a wheel of the wagon to be stopped.
  • This corner is extended forward in the direction of its point by a tongue resting on the running rail and on which the car wheel must bear.
  • the device or shoe has a handling handle.
  • the shoe further comprises, on the part of the corner in contact with the running rail two strips of low height forming means for guiding and fitting the shoe on the rail.
  • This known device has a number of drawbacks.
  • the shoe rests on the rail by its own weight so that it risks being ejected by the untimely contact of any object, moved by vibrations or even removed by inattention.
  • this device is simply placed on the rail prohibits its use on a running track located above the ground, for example on a track for an overhead crane, because the risks of the device falling constitute a permanent danger for personnel and materials below.
  • a safety shoe for slowing down and stopping rolling machines on rails which comprises a body formed by a tongue bearing on the rail intended to be engaged under the wheel of the vehicle to be stopped and a cleat forming a stop for the vehicle wheel, a shoe for fixing the shoe to the rail being articulated on said body and a lock being provided for immobilizing the shoe in position closing.
  • this shoe has the disadvantage of comprising relatively complex parts forming part of the claw.
  • this shoe can not be used on portions of track whose rails have connecting fishplates because the shoe claw abuts on the fishplates without being able to avoid them.
  • the invention aims to remedy these drawbacks by creating a slowing and stopping device of the type described in the aforementioned patent application, which combines great simplicity of manufacture with rapid installation and removal compared with existing devices.
  • a slowing and stopping device for vehicles traveling on rails comprising a body intended to be placed on the rail in order to receive a wheel of a vehicle to slow down and stop and forming a stop for this wheel.
  • the securing means consist of a plate carrying elastic claws kept apart in the rest position, said plate being intended to be applied to the rail and being articulated on means for bringing said claws together for tightening on the rail flange, said bringing together means being integral with the body of the device.
  • the slowing and stopping device shown in Fig. 1 mainly comprises a support and braking body 1 constituted by a tongue 2 on which a wheel of a device to slow down or stop, a cleat must rest. inclined 3 forming a stop for the wheel of the machine, made integral with a sole 4 which has ledges 5 for guiding and fitting the shoe on the flange of the rail R.
  • a device for securing the shoe and the rail At the end of the body 1 opposite the tongue 2 is fixed a device for securing the shoe and the rail.
  • This securing device shown in detail in Fig. 2 to 4 comprises a plate 7 made of sheet steel constituted by a U- shaped piece 8 with uneven branches, reinforced by a vertical veil 9 welded inside the U-shaped piece.
  • the veil 9 is arranged along the longitudinal axis of symmetry of the plate 7 and consequently separates this plate into two equal parts.
  • two claws 10 and 11 On the plate are articulated on either side of the web 9, two claws 10 and 11 intended to come into engagement with the flange of the rail R in the manner shown in Fig.2.
  • the claws 10 and 11 are made of spring steel wire.
  • Each of the claws comprises a first rectilinear section 12 which crosses the branches of the U-shaped part 8 through orifices provided for this purpose; the first straight section 12 is extended by a loop 13 which, as shown in FIG. 2, has an inclined portion 14 which departs from the first section 12, this inclined portion being followed by a practically vertical portion 15, extended to its turn by a portion 16 folded down so as to be able to trap the flange of the rail R.
  • each of the claws 10 and 11 is mounted oscillating in the plate 7.
  • This plate has in its rear part a tubular part 19 welded to the U part 8 at level d e the junction of its rear branch with its horizontal part.
  • the piece 19 is crossed by a pin 20 by means of which the plate 7 is articulated on a box 21 of generally parallelepiped shape made integral with the rest of the shoe by means of a rod 22 welded by one of its ends to the box 21 and by its other end to the body 1 of the shoe.
  • the housing21 has in its lateral faces notches 21aöns to allow a separation of the claws 10 and 11 during the coming of the shoe at the height of connecting fishplates between two sections of rail.
  • the housing 21 Inside its front end wall, opposite the hinge pin 20, the housing 21 includes a part 23 for limiting the rotation of the plate 7 relative to the cover, so as to prevent this plate from completely out of the housing when removing the shoe.
  • openings 24 In the side walls of the housing 21 are formed openings 24 in which are mounted leaf springs 25 whose free ends bear on the approximately vertical sections 15 of each of the claws 10 and 11 in order to maintain their loop 13 in taken on the rail flange as shown in Fig. 2.
  • the slowing and stopping device shown in Figs. 2 to 4 has been designed to be able to be used on sections of tracks whose rails have connecting ribs.
  • its claws When the device is locked on a rail, its claws must be able to move apart when the device comes to the height of connecting fishplates.
  • each of the loops 13 of the claws 10 and 11 has in its lower section 16, a part 26 which can be clearly seen in Figs. 3 and 4 and which deviates from the axis of symmetry of the device .
  • the claws 11 and 12 may have the form shown in dashed line in Fig. 3.
  • the housing 21 may have solid side walls, without the notches 22 or the springs 25 for holding the claws.
  • the device which has just been described operates in the following manner.
  • the mounting of the claws 11 and 12 in the plate as well as their shape are such that when said claws are free, they tend to take, because of their elasticity, positions spaced apart from one another, so to allow the passage of the rod of the rail R. between them.
  • the device can be grasped by the operator by the rod 22 of connection between the housing 21 and the body 1 which also serves as a handle.
  • the cover then occupies the position shown in phantom in Fig.3, the claws 10 and 11 are spaced apart due to their natural elasticity.
  • the plate 7 abuts by the front branch of the U-shaped part 8 against the stop 23, so that it can only partially exit from the housing 21 and does not interfere with the manipulation of the device.
  • the device When the device according to the invention is to be placed on a rail, the device is placed so that the plate 7 is supported on the rail, the claws 11 and 12 being in the open position, then the assembly constituted by the body 1, the tongue 2 and the housing 21, so that this assembly comes into contact with the rail R.
  • the tongue 2 is pressed against the rail, the edges 5 of the sole 4 trap the flange of said rail and the housing 21, by turning around the pin 20 causes the claws 11,12 to come together, so that the portions 16 of said claws grip the flange of the rail as shown in Fig.2.
  • the device is then in place and can perform its slow motion function and stop.
  • the assembly constituted by the tongue 2, the body 1 and the housing 21 by the rod 22 forming a handle.
  • the housing 21 rotates relative to the plate 7 around the spindle 20 and its side walls release the claws 11 and 12. These, due to their elasticity, deviate from one another and therefore no longer trap the flange of the rail R.
  • the device which has just been described is extremely simple to handle, because its installation and its connection with a rail are ensured by a single and same gesture, which consists simply in placing the sole 4 on the rail, the approximation between the claws 11,12 being produced during the relative movement of the plate 7 inside the housing 21, under the effect of the weight of the assembly.
  • the removal of the device is also ensured by simple pulling on the handle 22 which causes the lifting of the assembly, tongue 2, body 1 and housing 21, which causes the release of the claws 11 and 12, and consequently their spacing under the effect of their elasticity.
  • the device according to the invention is produced using very simple parts, requiring no machining operation for their assembly, so that the device has a low cost price.
