BEVEL.

SPECIFICATION forming part of Letters Patent No. 371,210, dated October 1], 1887.

Application filed June 17, 1887. Serial No. 241,615. (No model.)

To aZZ whom it may concern.-

Be it known that I, HENRY L. N ARAMORE, of Sharon, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Mechanics Rules or Gages, of which the following is a specification.

My inventionhas for its object to provide an improved gage or rule for cabinet-makers, carpenters, joiners, and other mechanics, whereby the dimensions and angles or form of a thing may be readily ascertainedas, for example, where it is desired to ascertain the length and angles of the sides and ends of a board to be filled in a frame-work or casing or between two walls or points.

It not infrequently happens that carpenters, cabinet-makers, and others are in the prosecution of their work required to fit boards in casings or between walls, partitions, or the like, where the angles of the ends of the board to be cut differ from each other, or are other than a right angle to the edge of the board, or both. This necessity arises, for instance, quite often in the building of a staircase. Various expedients are resorted to for obtaining the dimensions and form ofa board to be fitted in such place, all of which consume a considerable amount oftime and are attended with more or less perplexity to the workman, and unless the utmost care is exercised inaccuracy will result.

My invention consists in an extensible bar or rod provided on each end with an adjustable arm gage or rule, each of which arms may be adjusted to any angle with respect to the bar or rod, whereby the length of a board and the angles of the sides or walls of the casing or theliketo which it is to be fitted may be quickly and accurately ascertained.

Reference is to be had to the accompanying drawings,and to theletters of reference marked thereon, forming a part of this specification, the same letters indicating the same parts wherever they occur, of which drawings Figure 1 represents a perspective view of the invention in opened position. Fig. 2represents a longitudinal vertical section of the invention in closed position, the section being taken on the line w m, Fig. 3. Fig. 3 represents a bottom plan view of the invention in closed position.

a, to the lower end of which stud is affixed a block, (1, adapted to slide in a shallow groove, 6, formed in the bottom of part c. It is obvious that block d might constitute an integral part of stud b.that is, be formed as a kind of head to said stud-the upper end of which is screw-threaded to receive a thumb-nut, f. To

the inner end of part a is secured a stud, g, j

which extends upward through a slot, h, in part a, and is provided on its upper end with a thuinbnut, 2', as shown. By loosening the thumb-nuts the bar may be extended or shortened within limits permitted by its construe tion, and when moved to desired position it may be secured in such position by turning down the thumb nutsf 2'. Again, it is obvious that either of the studs by may be provided on its upper end with a simple head, the other having a thumb-nut, as shown, one such thumbnut being sufficient to secure the parts in adjusted position.

Each arm C is provided with a slot, j, to receive the shank of a bolt or stud, 7a, in the outer end of each part a a, by means of which each of said arms maybe moved to any position on its respective part within the limits of slot j, adjusted at any angle with respect to the bar, and fixed or held in such adjusted position by means of the thumb-nut Z on the upper end of stud 70.

It is obvious that the bar A and arms 0 may be marked off in inches and fractions thereof, and in some instances I have constructed the device in this way.

The arms 0 are preferably of such form that they may be folded under the bar, as represented in Figs. 2 and 3, so the device, when in closed position, will constitute a bar of rectangular form, convenient for transportation and packing.

Having thus explained the nature of my invention, what I claim is-- A tool or gage for wood-workers and other mechanics, consisting of an extensible rod or bar, A, consisting of the two parts a a, the

former provided with a slot, h, and the latter In testimony whereof I havesigned my name with the slot 0 and shallow groove e, a thumbto thisspecification, in the presence of two subscrew, f, on the inner end of part a, having its scribing witnesses, this 13th day of June, A.
