Abstract:

A draftsman's stippling device, small enough to be manually held during use, includes a vibratable cantelever bar supported in a small housing and having a free end projecting to the outside on which end a stippling pen is mounted. A cam disk having lobes about its periphery is adapted to be rotated by means of a battery powered mini-motor and reduction gearing at high speed against the upper surface of the bar. The lobes on the spinning cam disk successively depress the bar against the opposing tension of a return spring, whereby the bar and pen rapidly vibrate as a unit to enable stippling of a drawing surface disposed below the pen.
