Description

NITED SfrrvrnsV PATENT QFFIon FREDERICK VEAZIE, OF WORCESTER, MASSACHUSETTS.

IMPROVEMENT IN TRV-SQUARES.

Specication forming part of Letters Patent No. 182,620, dated September 26, 1876 application tiled April 20, 1876.

To all whom t may concern Be it known that I, FREDERICK VEAZIE, of the city and county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in the Construction of Squares, the following specification being a full description of my invention, reference being had to the annexed drawings- Figure l being a plate View of a completed square. Fig. 2 is a view of the inside construction, one half of the beam being removed, and showing the form of making the blade and attaching it to the beam, the dotted lines being the outline ofthe beam beneath. Eig. 3 is a sectional View of the beam and tongue, or shank of the blade, as seen from the end of the bealn, or from a section cut at the line drawn from m to m in Fig. 1, showing the manner ofrecessing the beam, and how the blade is itted into the recess, whereby each piece ties the others, and the Whole are held firmly in place.

In the construction of my square the blade is made of steel or other suitable material, with a shank at a right angle with the `eX- posed part ot' the blade, (formed in the manner shown in Fig. 2,) the shank being fitted tightly into a recess made into each half of the beam, the recess in each piece being the depth of half the thickness of the blade, or the recess may all bein one piece ofthe beam without departing from the principle of my invention. The beam may be made ofsteel or other suitable material adapted to the use of the tool, being made with a recess (as shown and described) intovwhich the blade is fitted, when the whole may be riveted together, whereby, by this manner of construction, the liability of the square getting out ot true is obviated, and accuracy and durability are secured, which adds greatly tothe value of the square.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a square, the combination of a blade pro vided with a shank at a right angle to the exposed part of the blade, with a beam recessed or grooved, the shank ot' the blade being fitted to said groove or recess, substantially in the manner and for the purpose specilied.
