Abstract

1,130,714. Grinding. MINNESOTA MINING & MFG. CO. 28 Jan., 1966 [8 Feb., 1965], No. 4006/66. Heading B3. A device for facilitating the grinding of workpieces W comprises a cylinder 16 which is attached to a table 14 for supporting a workpiece and has a piston 17 movable parallel to the table and secured to a workpiece-urging pusher plate 18, a fluid line 30 for supplying fluid under pressure to the cylinder, an infinitely variable valve 25 in the line for either quickly or slowly increasing or decreasing the pressure of fluid supplied to the cylinder, and a lever 33 for actuating the valve. As described, the grinding is effected by an abrasive belt entrained about a contact wheel C and the cylinder 16 is attached to a block 15 horizontally adjustable on the table 14 which is secured to a sleeve 13 vertically adjustable on a pillar 12. An air supply is connected to a line leading to a filter, pressure gauge, control valve, oiler 23 and hose 24 which, in turn, is connected to the inlet of the infinitely adjustable control valve 25, the outlet 27 of which is joined by line 30 containing a speed control valve 28 and quick release valve 29 to the cylinder 16. The infinitely adjustable control valve 25 consists of a conventional pressure regulating valve having its normal screwthreaded adjusting member replaced by a plunger which is movable to effect variation of the pressure in line 30 and cylinder 16 to vary the pressure with which the pusher 18 pushes the workpiece W against the bolt by movement of the lever 33 about a pivot adjacent the valve, the movement being effected by the knee of an operator engaging a pad 34 on the lever.
