Title: Improvements in or relating to tumbling material and method of finishing, deburring and polishing metal pieces
IPC: B24B31/14
Filed: 1955-04-07
Abstract: A tumbling material for polishing comprises dry fragments of a lightweight porous material, which has a specific gravity of about one and a largest particle dimension within the range of 1/4 -\ba1/32 inch, embedded on the surface of which is a film of dry abrasive powder grains which preferably have a largest particle dimension of about 1/100 inch.  These powder grains may be either embedded in the larger fragments by rolling, or be made adherent thereto by a solution of "Tylose" (Registered Trade Mark) varnish or other adhesive with which the larger fragments may be coated.  The larger fragments are preferably either of pumice or or of cement which has been rendered porous by aerating an unset cement mixture with air or carbon dioxide.  The abrasive powder coating is preferably aluminium oxide which may be picked up and held on the surface of the fragments by pumice powder.  In general about 15 parts of the porous fragments are used per part of abrasive powder.  The compositions are of particular use in polishing and deburring fine lightweight metal stampings by tumbling.

Title: Braking device
IPC: B60T7/20
Filed: 1974-03-08
Abstract: 1461603 Over-run internal shoe drum brakes FTF 8 March 1974 [20 March 1973] 10398/74 Heading F2E A two part shoe for a drum brake allows radial inward movement of one part relative to the other to reduce the braking effect in one direction of drum rotation, the connection between the parts comprising a flange on one part sandwiched between parallel flanges on the other. As shown, the right-hand shoe 29 consists firstly of an arcuate braking member in the form of a web 100 with attached friction lining 31, the web including elongated openings 102, 103, 104, each opening having its median line inclined with respect to a radius through the opening. Shoe 29 consists secondly of a support member in the form of two flanges 101 disposed on either side of web 100 joined by end members 107, 108, and by pegs 105, 106, extending through slots 102, 104, respectively with slight play. In operation, on over-running, slidable part 6, Fig. 2, of telescopic pole 3 moves to the right relative to the towed vehicle and pivots a lever 10 about pivot 11 to pull a control rod 15 to the left, whereupon the shoes 29, 30 are separated at their upper ends by mechanical device 26. The direction of rotation of the drum (not shown) is indicated by arrow 36. Shoe 29 is urged in the same direction by frictional contact with the drum until the lower ends of slots 102, 194 engage pegs 105, 106 respectively, the braking member 100, 31 being urged radially outwardly during this movement because of the inclination of the slots, and the brake is applied. When the towing vehicle is being reversed, part 6 again acts on control rod 15 to separate the upper ends of the shoes, but the drum rotation is now reversed so frictional contact of braking member 100, 31, with the drum now results in the upper ends of slots 102, 104, engaging pegs 105, 106 respectively with consequent inward movement of the braking member 100, 31, so the brake is effectively released. For hand operation for parking, a lever 25 is rotated clockwise about pivot 11 and, through a compression spring 18, pulls rod 15 a greater distance so that shoes 29, 30 are moved further away.
