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.

Abstract: A rear view mirror assembly for use in combination with a collapsible infant stroller of the type having an extendable handle part. The assembly includes an adjustable bracket for engaging the handle part, a mirror, and a position-adjustable member for connecting the mirror to the bracket. The mirror is movable between a first position, wherein the mirror is located in view of the infant occupant, when the stroller is in use, and a second position, wherein the mirror is adjacent the stroller, when the stroller is collapsed. A cushion surrounds the periphery of the mirror to protect the infant from injury.
