MARKING-GAGE.

SPECIFICATION forming part of Letters Patent No. 349,330, dated September 21, 1886.

Application filed May 20, 1886.

To all whom, it may concern,.-

, Be it known that I, CHARLEs E. ZIMMER- MANN, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Carpenters Gages, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention consists in a novel construction of a gage designed for Ause in carpentry, and to accurately, quickly, and conveniently mark or print out the locations and outlines of mortises to be cut. In the accompanying drawings, Figure l is a plan view of Iny invention as employed for marking on 'a Window-frame the mortise for Fig. 2 is a face view of the gage. Fig. 8 is a side view of the same; and Fig. 4 is a transverse section on line x x, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents a straight bar adapted togbe inserted in the groove B, which is usually formed in the vertical sides of the window-frame for the reception of the dividing strip between the two sashes ofthe window. One end off the bar A has secured to it a plate, a, which projects at right angles from opposite sides of said bar, and forms laterally-projecting abutments thereon, for the purpose hereinafter explained. To the opposite end of the bar A are adj ustably connected two arms, C C', which project from opposite sides thereof, andare provided with slots b b at right angles'to the bar A, through which slots pass the screws c c, which fasten the said arms on the upper side of the bar. The free ends of the arms O C have integral withthem or rigidly attached to them bars O O,"which.are thus carried 1ongtndinally by the sides of the bar A, and the 'under side of said bars are provided with pricking or marking points e e, which stand in rows parallel with the bar A, and are properl y spaced, so that when pressed into the surface of the window-frame each impression of said points shall indicate the center into which to insert the point of the auger by which the mortise is to be bored out, as represented by dotted lines in Fig. 1 of thedrawings.

In using my invention the bars C C are to be set ont from the sides of the bar A, to bring the rows of points e e to coincide with the lon- Serial No. 202,721. (No model.)

of the groove B by the mortise D, cut in the side piece of the window-frame for the attachment of the top cross-piece of said frame. The bars O C are thus carried at the requisite distances` from the mortise D to correspond to the distance required between the top rail or cross-piece of the window-frame and the sashpulley. After the' gage is placed in its aforesaid position a blow or pressure applied to the back of the bar A causes the markers or points e e of the bars C C to make their impressions in the surface of the side rail of the windowframe. A series of such side rails may thus be marked uniformly, accurate, and expedi- .the bar A. Neither-d'0 I limit myself to the employment of two marking-bars at opposite sides of the bar A, because in some cases only one of said marking-bars may be required.

What I claim as my invention is The within-described carpenter-s gage, consisting of the bar A, provided at one end with the laterally-projecting abutment a, the laterally-projecting arms C C', adjustably connected to the opposite end of the bar A, and the marking bar or bars O C, arranged longitudinally by the side of the bar A and rigidly attached to the arms O C', substantiall y as specified and shown.

In testimony whereof I have hereunto signed my name and aiiixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 18th day of May, 1886.
