Abstract

430,934. Scales. GLOVER, H. S., 96, Stainbeck Road, Leeds. March 10, 1934, No. 7640. [Class 97 (iii)] A mensuration device comprises a body portion provided with a set of graduation marks and an index portion which is housed in a recess in the body portion and is movable or interchangeable to bring one of a number of sets of numerals into conjunction with the graduation marks thus providing a number of alternative scales in one instrument. As shown in Fig. 2, the body portion a has at one edge an inclined surface carrying the graduation marks, at the other edge a raised lip, and, between the two, a recess for the index portion b. The latter is of hexagonal cross-section, has six sets of differently spaced numerals one set on each face, and is held in the recess by springs c engaging annular grooves at the ends of the portion b. Locating pieces cl also engage the grooves in the portion b and ensure that the latter is accurately positioned relatively to the graduation marks. The portion b may be raised from the recess against the action of the spring c, turned to bring the desired face to the top and dropped back into the recess. In a modification in which alternative graduation marks may be used, the graduation marks are on an interchangeable part adapted to be attached to the body portion a by dovetail joints, clips, press studs or by utilizing the resilience of the part to spring it into engagement with studs on the body portion a. In a further modification the body portion is provided with a set of graduations on both edges and each set is provided with a rotatable index portion. The body portion may be in two separate strips with a rotatable index portion against the inner surface of each, the two strips being enclosed at the ends in caps and pressed apart by springs. In the form shown in Fig. 15, the graduation carrying strips a and retaining strips a<1> are mounted on a resilient base a<2> so as to form recesses for the index portions b. The latter may be withdrawn and adjusted by bending the base a2 transversely.
