The set-screw 24 is then clamped to hold the bar in its extended adjustment and the set-screw 23 is loosened. Now by rotating the crankwheel 22 the tool or pencil at the end of the bar will cut or draw a curved line, and if it be desired to cut parallel curved lines by operating the ratchet-lever 18 this may be accomplished.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of the invention will be readily understood without requiring further explanation.

The device is exceedingly simple in construction, strong in parts, and may be placed upon the market at comparatively small cost.

'While I have shown and described the preferred embodiment of myinvention, I would have it distinctly understood that I contemplate and reserve to myself the right to make such changes as fall within the scope of my claims.

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

1. In an instrument of the character described, the combination with the track, of a carriage mounted to reciprocate thereon, a beam having a sliding engagement in said carriage, means for sliding said beam lengthwise, said beam being provided with a head, and a tool-bar rotatably connected with said head, and provided with means for locking it, substantially as set forth.

2. In an instrument of the character described, the combination with the track, of a carriage mounted to reciprocate thereon, a

beam having a sliding engagement in said carriage, a ratchet-wheel carried by said carriage and provided with a screw-shaft, a nut engaged with said screw-shaft and adj ustably connected with said beam, said beam provided with means for clamping and holding a tool or pencil, substantially as set forth.

3. In an instrument of the character de- 4:. In a tool of the character described, thev combination with the standard, a post journaled therein, a pulley journaled on said post, a track connected to said post and provided .at its outer end with a foot having means for fastening it stationary, a carriage adapted to slide on said track, acord or connection wound about said pulley and having one end secured to the carriage at one point and the other end passing around a sheave journaled to the outer end of the track and secured to the carriage at another point, and a beam having a head at one end, means for longitudinally adjusting the beam, and atool or pencil bar rotatably connected with said head and provided with means for fixing the tool-bar to said head, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
