MAT-GAGE FOR PlCTURE-FRAM ES.

SPECIFICATION forming part of Letters Patent No. 313,197, dated March 3, 1885.

Application filed September 3, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDWARD L. GAYLORD, a citizen of the United States, residing at Bridgeport, in the county of Fair-field and State of Connecticut, have invented certain new and useful Improvements in Mat-Gages for Picture-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel and useful improvements in mat-gages for pictureframes, and has for its object to provide a device of this description by means of which the corner angle of the mat may be protracted either from within or from without, and the point of protraction determined without recourse to compasses or any means other than my device; and with these ends in view my invention consists in the details of construction and combination of elements hereinafter fully and in detail set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may more fully'understand its construction and operation, I will proceed to describe the same in detail, referring by letter to the accompanying drawings, forming a part of this specification, in which Figure 1 represents my device in position upon a picture-mat to determine from without the angle the point of protraction desired; Fig. 2, a central longitudinal section of my device and a perspective of one of the flanges; Fig. 3, my device applied to amat to protract the angle thereof from within.

Similar letters denote like parts in the several figures of the drawings.

A is the body of the gage, constructed from thin sheet metal, and having the corners C E G thereof right angles. Along the sides B C and D E of the gage are flanges F, (see Fig. 2,) projecting downwardly and at right angles thereto. These flanges terminate at the points B D, respectively. H is a projecting strip formed integral with the body A. Bisecting the angle G, and extending across the body of the device,is a line of perforations, I, through the metal, and spaced as may be desired from one another-say one-eighth of an inch. This line of perforations is continued to the end of projection H.

The operation of my improvement is as follows: The angle whose protraction it is'desired to obtain havingbeen determined and cut, the gage is, if the protraction is to be inward, placed upon the corner of the mat (see Fig. 1) and pushed forward until the flanges F rest against the edges of the mat. The line of perforations will then bisect the corner angle of the mat, and the desired point of protraction is then readily indicated by a pencil or punch mark made through one of the perforations in the gage. These points having been determined as described at the various corners of the mat, straight lines or cuts may readily be made between them. In protracting an angle from within outward, as may be sometimes found convenient, the projection H is laid upon the mat, as seen at Fig. 3, and pushed forward until the flanges Frest against the inner edges of the mat. The point of protraction may then be readily indicated, as before, by means of a mark made through one of the perforations in the pro jection H.

In my invention I do not wish to be confined to the exact shape or construction shown and described, as the gist of my invention rests in the broad idea of constructing a g for a given angle, whereby it may be readily and correctly protracted either from within or without.

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

1. The gage as described, the same consist ing of a flat sheet of metal having an outward projection from one corner thereof, and in the same plane provided with a line of perforations extending diagonally across its face and along the center of the projection, and having upon the two sides contiguous to said projection flanges extending downward and at right angles to the body of the gage, substantially as set forth.
