CARROLL THOMAS, OF LINCOLN, ILLINOIS.
BEVEL AND TRY SQUARE.
SPECIFICATION forming part of Letters `Patent No. 252,065, dated January 10, 1882.
Application filed May 31, 1881. (No model.)
To all whom it may concern:
Be it known that I, CARROLL THOMAS, a. citizen of the United States, residing in the city of Lincoln, county of Logan, and State of Illinois, have invented a new and useful combination of mechanical tools by which the implement known among carpenters as a trysquare, by certain transpositions, may be ch anged from that implement toa bevel-square, a miter-square, or a gage and rule, and may also be converted into a level or plumb; and I do hereby declare the following to be a description of said invention7 which will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, forming part of this specification. t t
This implement may be constructed of metal, or part metal and part wood, the latter being preferred. t
In the drawings, Figure l represents what carpenters denominate a try-square 5 Fig.2, a bevel square; Fig. 3, ainiter-square; Fig.4, a gage and rule; Fig. 5, a level, and Fig. 6a
plumb.
` what. I call the handle of a try-square, and
letter B an adjustable blade ot' the same.
Letter C represents a slot cut longitudinally through blade B, one end of'which is enlarged into a square form, (represented by D,) and said slot, from the square form aforesaid, terminating in the form of a curve, as represented by letter O.
Letter E represents a thumb-screw in the end of handle A, passing through one side of Vsaid handle and through the blade B into an adjustable square screw-nut, H, made to fit into the portion ot' said slot represented at D.
The blade of the square, instead of being rigidly confined in the end ot' the handle, is so constructed as to slide smoothly and easily through it..
When used as a try-square, as in Fig. l, the end of the blade is so inserted in the handle that the turning of the thumb screw will press the nut H into that portion ot' the slot represented' by D, and by being closely screwed makes the implement a tirm and solid trysquare. To convert it into a bevel-square, as shown in Fig..2, the thumb-screw is loosed, so that the nut will pass out or" the slot at I). Then lift the blade and press the opposite end of it downward. The rod ot' the screw will pass into the rounded part of' the slotat O. When the angleis made screw the parts closely together. To convertitinto a miter'square the blade is loosed in the same manner as before stated, and the opposite end raised untilit reaches the degree required. Then sei-ew it closely, as in Fig. 3. Any desired angle may be made in the saine manner. To convert it into a 'gage and rule, as in Fig. 4, slide the blade through the end of the handle to the position desired, being the distance betwt en the marker (represented at letter I) and the handie, and make it` tight u ith the thumb-screw.
. What I claim as new, and desire to secure by Letters Patent, is-
The blade of a try-square or bevel constructed in manner and form as herein described, in combination with thumb-screw and adjustable nut H, as described and setforth. t
CARROLL THOMAS.
