IMPROVEMENT IN MACHINES' FOR C'OPING SASH.

Specification forming part of Letters Patent No. 41,706, dated February 23, 1864.

Vmode of coping or scribing window-sash bars at their intersection or angles and I do hereby declare that the following is a clear and exact description thereof, reference being had to the annexed drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the form of a gouge or cutter worked by means of a slide and lever, which hasthe cuttingedge or point so formed as to strike the bar in an oblique or angular direction to the center of the gouge or cutter, as shown by F F,

. Fig. 2, thereby obviating the diiiiculty ot' splinterin g the bar when cuttin g directly through and across the ber of the wood at one cut, which would be the natural conse quence of a cut made directly through the bar by a common gouge as used by hand, the bar in that case having to be turned over and cut from both sides, which is still liable to splinter from a slip of the hand or gouge.

In order that others may construct or use my improvement, I will 'further describe it as follows Figure l is the plan. Fig. 2 is the longitudinal elevation. Fig. 3 is a transverse section. Fig. 4 is the front or operating side. Fig. 5 is the perspective.

A A, Fig. 2, is the bed-plate, on which to construct the slide and lever.

B B B, Fig. 2, is the stand through which Y the slide works.

C C, Fig. 2, is the lever.

D D, Fig. 2, is the slide.

E, Fig. 2, is a movable collar, by which the gouge is adj usted to the mounting on the bars.

F F, Fig. 2, thergouge or cutter.

G, Fig. 2, is a stop for the bar to prevent the gouge cutting too deep.

H, Fig. 2, is a back or rest, with a loose L piece, I, attached by means of two small setscrews, as shown in perspective, Fig. 5, to support the bars while being cut, or in other words to resist the pressure of the gouge or cutter.

K, Fig. 2, is a flange, by which to hold the machine in a vise or otherwise while being operated.

L, Fig. 2, shows the section of a sash-bar in position to be cut, which is done by moving the lever from left to right, or, in other words, directly forward toward the bar, when it will produce the direct cut.

What I claim as new, and desire to secure by Letters Patent, is-

The combination of gouge F, slide I), and lever C, when constructed and operating substantially as described. 1
