Title: Improvements relating to the control of operating means in a grinding operation
IPC: G01B11/08
Filed: 1950-09-14
Abstract: 690,293. Photo-electric gauges. JONES & SHIPMAN, Ltd., A. A., and HOULDSWORTH, J. Aug. 15, 1951 [Sept. 14, 1950], No. 22603/50. Class 40 (iii). Apparatus for effecting control of a grinding operation comprises a pair of mirrors between which multiple reflection of a light beam takes place, one mirror being moved by the work-piece and a light-sensitive cell receiving the emergent beam and effecting the control. As described, the invention is applied to gauging the diameter of a work-piece 7 which is being ground. The mirrors, light source and photo-cell are mounted in an arm which can be swung about a pivot 48 on the machine into contact with the work. A stop 10 is so adjusted that the ends of the workpiece diameter are engaged by a fixed stop 6 and a movable stop 16. As the diameter of the work is reduced the stop 16 is maintained in contact with the work by a spring 14 which at the same time depresses a rod 17 to rock a pivoted mirror 19 against a spring. This mirror receives collimated light from a source 38 and redirects it to a mirror 31 mounted on a member 28 which is spring-hinged at one end. Multiple reflections of the light take place between these two mirrors until the work diameter is sufficiently reduced when the beam passes through an aperture 28 to a photo-electric cell 35. This cell feeds an amplifier which rocks the top mirror by means of a solenoid 33 allowing further final grinding to take place before the cell receives the light beam again when the grinder is stopped. The cell may act to reduce speed when it receives the first light beam. The two successive signals may be produced by making each mirror of two side-by-side halves at a slight angle to each other so that as the feeler moves the cell receives light first from one pair of surfaces and then from the other. Both mirrors may be pivoted if desired, so as to be actuated by feelers on the work-piece.
