TRY-SQUARE HANDLE.
Specification of Letters Patent.
Patented Feb. 22, 1921.
Application filed October 22, 1919. Serial No. 332,368.
face to be flush with the face of the try square for permitting mortises to be marked easily and expeditiously.
In the drawings: l v
Figure 1 is 'a top plan view of the improved square;
Fig. 2 is an endview, looking at the end of the handle remote from the blade;
Fig. 3 is an end view, looking at the opposite end;
Fig. 4c is a view looking at the edge of the handle.
In the present embodiment of the invention the try-square comprises a blade 1 of metal or the like and a handle 2 of wood. This handle has at one end a mortise in which is received one end of the blade, and the blade is connected to the handle by means of rivets 3. At one face of the trysquare and at the inner side edge of the handle it is rabbeted from end to end, to form a shoulder 4 and a surface 5 at right angles to the shoulder and flush with the adjacent face of the blade.
Referring to Fig. 1, it will be seen that the width of the rabbeted surface is slightly greater than half the width of the handle,
and in the present instance this rabbeted surface is an inch in width. Upon the end of the handle remote from the blade, andon that portion of the end adjacent to the rabbeted surface, there is provided a scale 6, one inch in length, and suitably graduated, and that side edge of the handle adjacent to the blade is also provided with a scale indicated at 7.
Thus it will be evident that two shoulders are provided for engaging the edge of the ob eet upon which the blade is to be used, namely, that shoulder 4 formed by the fabbet, and that shoulder8 at the opposite side of the blade, that is, the inner side edge of the handle. r
The use of the improved blade will be evident from the description. Either shoulder 4 or 8 may be engaged with the edge of the work, as indicated inFig. 2, and the blade extends perpendicularly to the long axis of the work, lying upon the surface thereof.
I claim: A try-square comprising a handle and a single blade secured thereto with its sides in parallel relation to the planesv of the handle and at right angles thereto, the blade extending entirely across one end of the handle and being graduated, and the edge of the handle toward the blade being cut away or rabbeted to define a surface flush with one side of the blade and a right angular shoulder extending the full length of the handle, the portion of the blade between the inner edge of the handle and the shoulder being also graduated.
