As best shown in Figs. l and 4, the plate g is provided with a rectilinear Wall c, dis-V posed at right-angles thereto and parallel with the longitudinal axis of the sleeve, this being a matter of convenience in the use of the device.
The parts thus described may be used to great advantage for drawing curves or circles. After a pencil m has been disposed in the sleeve as shown in Figs. l and 2 it may be secured therein against longitudinal movements by the set-screw which is threaded in the wall f, the set-screw bearing upon the plate g and operating, when rotated, to cause the resilient plates to move. toward each other for coincidently compressing the pencil in the sleeve and securing the pencilholder in stationary relation with the scalestrip.
The device, as described, may have any desired length or proportion, and in instances Where a greater length than ordinary is required, the scale-strip, at its distal end, is provided with a roller or caster n, the pintle p of the caster being preferably provided and circumscribed by a spring s disposed in the housing or cylindrical terminal part t of said strip, a Washer w being interposed between the head of the pintle and the upper end of the housing and suitabiy secured thereto. i
The device is very convenient in use for any of the purposes mentioned. The holder ll may be readily mounted upon the scalestrip since the plates f and g are not connected at their lower ends, and the pencilhelder may have slidable movements on the strip", the stem of the screw engaging in the slot 9.
