JUSTUS A. TRAUT, OF NEW BRITAIN, CONNECTICUT.

IMPROVEMENT IN CARPENTERS GAGES.

Specification forming part of Letters Patent No. 132,421, dated October 22, 1872.

To all whom it may concern:

Be it known that I, JUsTUs A. TRAUT, of New Britain, county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Carpenters Gages; and to enable others skilled in the art to make and use the same I will proceed to describe, referring to the drawing, in which the same letters indicate like parts in each of the figures.

In the accompanying drawing, Fig. 1 shows a side view of a gage made after this improvement, Fig. 2 is the same taken apart to show its several parts; Fig. 3 is a plan view of same;

Fig. shows side and end views of the metal gib detached; Figs. 5 and 6 show elevation and plan views of a gage of ordinary construction.

a is the slide-head, having metal plates b giged into and made flush with the faces thereof. c is a thumb-screw by which the head a is firmly held in the desired position. at is a stock made in the common way. ff represent my improved stock made in two parts, kept apart the one from the other, each half being-provided with a groove, g, to receive the metal parts. it h are metal pieces placed at the ends between the two parts ff, and the whole being riveted together after the metal sliding frame h is inserted in its place between the two parts f f. iis an elongated thumbscrew fitted into a bearing in the hub 70 of the end piece h and is held in place free from endwise play by a screw-collar, I, turned up to the end piece and secured, and the screw fitted into a screw-nut, 1 formed in the sliding frame h so that by turning the thumbpiece 1 the slide k can be moved with its gagetooth m, inserted through the metal slide k back and forth at pleasure to any desired position relative to the tooth m in the end piece h. g shows a side and edge view of a metal gib fitted to the thickness of the heads a. The end pieces h h slide W, and gibs are first cast, then compressed in dies to bring them to a uniform width and thickness. A gage provided with these gibs, as shown and set forth, affords perfect security against defacing the stock, and the heads are held more perfectly with less pressure by the thumb-screw. By this mode of manufacture they are made cheaper, better, and more desirable for trade and use.

What I claim as my invention is- A carpenters gage constructed, substantially as set forth, of the parts f f, metal plates h h, slide h and screw 'i, operating in combination with the head a and gib q,substantia1ly' as and for the purpose specified.
