Claim 1
Independent Claim
147 words
A burnishing tool for transferring indicia from a carrier sheet to a receiving surface, the tool comprising an elongated barrel having a bore in it, a movable plunger mounted in the bore, spring means urging the plunger out of the bore, stop means limiting the travel of the plunger out of the bore, a fixed ball tip formed integrally with the plunger and projecting from the bore to provide a spring-loaded burnishing surface, and means for adjusting the force applied by the spring to the plunger comprising a shank threaded into the bore and engaged with the spring to adjust pressure in the spring, and an elongated handle formed integrally with the shank and shaped as a flat blade to provide means for conveniently threading the shank into and out of the bore and to serve as a burnisher for the indicia transferred to the receiving surface.
