Abstract
329,516. London Electric Railway Co., and Burgess, H. T. C. May 25, 1929. Surface and outline gauges. - Relates to gauges for determining the diameter of cylindrical surfaces of the type having two stationary contacts a fixed distance apart between which is a movable contact the movement of which is transmitted to a pointer, and consists in securing the movable contact directly to or forming it integrally with the pointer. The fixed contacts 14, 15 are secured by rivets or screws to a sectorlike plate frame 10 having a handle 34. The frame is flanged at the edge adjacent to the contacts and provided with projections 19 to carry screws in the coned ends of which bear the pointed ends of the pivot pin 22 of a pointer 21 the end 26 of which forms the movable contact. The pointer passes through a slot in the flange and moves over a scale 33 which is calibrated by applying the gauge to cylinders of known diameter. A guide strap 32 is provided. In a modification, the frame is provided with a scale on each side and the pointer is bifurcated at the end, one of the divided parts working over each scale. Two guide straps are provided in this case. A spring 29 normally holds the pointer against a stop 31.
