Application filed January 11, 1906. Serial No. 295,546.

To all whom it may concern.-

Be it known that I, J Us'rUs A. TRAUT, a citizen of the United States, residing at New Britain, Connecticut, have invented certain to embody my invention. Fig. 2 is a plan view. Fig. 3 is a section onthe line 3 3, Fig.

' 1. Fig. 4 is a section on the line 4 4., Fig. 1.

Fig. 3 is a face view of the handle or back portion of the try-square shown in Fig. 1

looking from left to right, the blade of the square being removed.-

1 is the usual blade ofa try-square, which may be graduated in any'desired mannerf The back or handle portion of'the try-square is formed of a single piece of metal and comprises'two side members or checks 2 2-. (See section Fig. '3.) These checks are spaced apart the thickness of the blade 1.

2 is the face portion of the back. This face affords a broad bearing-surface, and. it

- determines one of the inner sides. or angles being folded back upon themselves.

of the square.

portion 2 is of double thickness, thesides These sides are then extended straight back and parallel to each other to form the cheek mem bers already referred to. The face 2 is centrally slotted at one end, as indicated at 3,

. may be a plain straight piece of metal, or it may be formed of a right angled piece of metal, as would appear in Fig. l,ignoring said dotted line, in which event one end of said bladewould act as a filler-piece between said Y the saving of metal.

The face 2" and the cheek pieces 2 2 are formed-integrally. As will be" seen by reference to Figs. 1, 2, and 3, the face m to the same, broadly. The particular construction herein disclosed is, however, from the standpoint of strength, economy,

and simplicity of manufacture unique and of substantial benefit and advantage. For example, the number of steps necessary to the complete production of the device is reduced to the minimum. Only two pieces of metal need be handled, the blade constituting one piece, the back the other. The addition of a separate filler-piece involves no dif-.

ficulties or complex operations, since it need I be but a plain piece of metal inserted between'the cheeks. The method of attaching the blade to the back may be any of the well-known methods already. practiced, such as riveting. I preferably form an elongated opening, as indicated in Figs. 1 and 4., in the cheeks 2 2, as it affordsa convenient fingergrip and results also in a saving in weight and What I claim is'v v 1. In a try-square, a blade, a back or handle portion comprising a face. and cheek members, said face and cheek members being formed integrally from a single piece of metal,

the,face being slotted to receive the blade,

the metal at the side edges of said face being folded back upon itself,-and then projected rearwardly to hold the blade and form a grip portion. 4
