Definitions

  • This invention relates to a device for allowing manual rotation of an axial brake rigging slack adjuster of the type with non-rotating barrel during normal operation on a railway vehicle by linear operational movement.
  • a so called axial slack adjuster is normally incorporated in the brake rigging underneath a railway vehicle. Occasionally, for example the replacement of worn-out brake blocks, it is required to manually operate the adjuster for restoring its length to the original value.
  • the adjuster As the adjuster is mounted underneath the vehicle, often in a position where it is difficult to reach, it is desired to effect the rotational movement from the side of the vehicle, preferably by linear movement back and forth of a handle of the like.
  • Some slack adjusters have barrels rotating in normal operation. There is, however, a tendency towards a type where the adjuster barrel is not rotating, whereas the manual adjustment may be brought about by rotation after a certain rotational lock within the adjuster has been overcome.
  • a device for remote manual rotation of a slack adjuster of the type with non-rotating barrel consists according to the invention of a sleeve to be coaxially attached to the slack adjuster, a collar coaxially mounted on the sleeve for rotation only and provided with means for pivotal connection to an operational rod, and a locking spring coaxially mounted between the sleeve and the collar for allowing relative rotation of these members in one direction only.
  • the operational rod extends preferably to the side of the vehicle and may there be connected to a handle arrangement for easy operation, for example by pumping motion.
  • the rod may, within the scope of the protection, be replaced by equivalent means, for example a wire with spring return.
  • Fig. 1 is a side view, partly sectional, of a device according to the invention and Fig. 2 is an end view of the device, a slack adjuster being indicated with a dash-dotted line.
  • the brake rigging underneath a railway vehicle generally includes a slack adjuster, in most cases of the so called axial type. Occasionally it is required to operate the adjuster manually, for example at the replacement of worn-out brake blocks, when the adjuster length is to be restored to its original value.
  • a device for this purpose consists according to the invention mainly of three coaxial parts: a sleeve 1, a collar 2 and a locking spring 3.
  • the sleeve 1 is to be attached coaxially on a housing or barrel of an axial slack adjuster.
  • a slack adjuster 4 as indicated with dash-dotted lines in Fig. 2, has a cross-sectional shape with diametrically opposed rims 4'.
  • the sleeve 1 has an inner cross-sectional shape corresponding thereto and is provided with screws 5 for its secure attachment to these rims 4'.
  • the collar 2 is rotatably arranged on the sleeve 1 but is held against axial movements by means of a locking ring 6. Towards its end, it is provided with sealing rings 7 for preventing the intrusion of dirt, moisture and the like. An ear 8 with a hole 9 is fixed to the collar 2.
  • the locking spring 3 is arranged as shown coaxially between the sleeve 1 and the collar 2 so as only to allow relative rotation between these two parts in one direction, as is well known to any person skilled in the art.
  • the described device is attached to a slack adjuster 4, and a rod 10, extending to a handle (not shown) at the side of the railway vehicle, is pivotally attached to the hole 9 in the ear 8, it will be possible to accomplish a manual rotation of the slack adjuster 4 in the pre-determined direction by operating the handle for moving the rod 10 to and fro in its axial direction as indicated with an arrow in Fig. 2.
