Title: Rail-scraper devices and installations
Inventor: WATKINS TERENCE JOHN
IPC: B61H7/06
Filed: 1998-02-05
Abstract: An abrasive block 1 used for scraping wet leaves, snow or ice from a rail R of a railway track in order to enhance traction, is urged onto the rail R by a piston 2 under oil-pressure within a cylinder 3. The pressure is created via a diaphragm 11 which separates the oil in the cylinder 3 from an air-chamber 12. Chamber 12 is supplied with air via a regulator 14, from the air-brake supply system 16 of the train, and has a dump valve 19 for dissipating air-pressure surges. A return spring 20 under the piston 2 is active in retracting the block 1 when air-pressure in the chamber 12 is reduced.

Abstract: -A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastics material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.
