Abstract

172,818. Humpage, A. J., and Finney, W. Oct. 18, 1920. Tools for setting-out work.-Comprises a combination tool for setting out work which may be used as a protractor, depth gauge, marking-out gauge and scribing block &c. The member 1 having at least one straight edge 2 is curved and provided with a protractor scale 18 on one face as shown. The member is provided on each side with a circular recess to accommodate a circular plate 13 the edge of which is split to the centre to receive a rule 19 which may slide relative to or turn with the plate 13. A projection 12 on the plate passes through a hole in the web between the recesses on each face and forms the pivot, being clamped in any adjusted position by a nut 16. The edge 19 of the rule forms the reading edge of the protractor and passes through the axis of the disc. The face of the device in which is located the recess 10 is also provided with a recess 22 square to the edge 2 and in which the rule may lie so that longitudinal motion only of the rule is possible. The device may be bifurcated at 7 to receive the rule, the latter being provided with a slide and scriber, a fine adjustment device also being fitted. Specification 162,048, [Class 106 (ii), Dynamometers &c.], is referred to.
