Abstract

892,229. Sliding-jaw gauges. SIMPSON, J. R. June 5, 1959 [June 13, 1958], No. 18900/58. Class 106 (2). A linear - dimension gauge comprises a main guide-bar 1 having projections 4 at regular intervals, a main slide 6 disposed on the guide-bar 1 with means 5 for engaging the projections, a cross-slide 9 with an inclined edge disposed upon the main slide 6 and a scale 13 attached to the bar 1 tc register with graduations on the cross-slide 9. The slide 9 is urged to the left against a stop 14 by a spring (not shown), and a further slide 10, with an edge mating with the inclined edge of the slide 9, is urged downwards by a second spring (also not shown) against the cross-slide 9. In use, an object to be measured is inserted between the slide 10 and a member 2 attached to the guidebar 1. The cross-slide 9 is then retracted, and the main slide 6 adjusted, by means of the member 5 mating with the projections 4, as close to the workpiece as possible. The crossslide 9 is then released and a measurement can be taken by use of the scale on the member 9 and a vernier on the member 10. The projections 4 may be in the form of teeth engaging a rack 5 as shown. Alternatively, a screw thread engaged by a split-nut or a set of balls or rollers engaged by suitably shaped members may be used. The apparatus may also be embodied in height or depth gauges.
