Abstract

Abstract A marker, which prints a concentric element such as a nut, bolt, or the like, for example, when moved into engagement with a surface, is retained adjacent one end of a base by magnets within the base. The marker is carried on a protruding portion of a support, which is slidably mounted within the base and carries a locating pin extending longitudinally therefrom and through the marker. When the locating pin is disposed on the surface at the point at which the center of the nut or bolt is to be located, a spring, which acts on the locating pin, is overcome by depressing the base so that the marker can be moved into engagement with the surface at the desired location. After printing, the marker is released from the effect of the magnets by pushing the support away from the base whereby the field of the magnets is no longer effective so that the marker drops off of the support by gravity.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 191 words
A device for supporting a marker or the like for printing on a surface at a particular location including: a base; means supported by said base for movement relative thereto; said base having means to releasably retain a marker on said supported means and adjacent said base; said supported means having a portion extending exteriorly of said base and cooperating with the marker to locate the marker exteriorly of said base and adjacent one end thereof; means to prevent rotation of the marker when the marker is on said supported means; means to locate the marker at the particular location on the surface for printing; said locating means extending longitudinally from the exterior portion of said supported means; means cooperating with said locating means to allow retraction of said locating means when said locating means is pressed against the surface so that the marker may be moved against the surface to print on the surface at the particular location; and means to produce relative movement between said supported means and said base to release the marker from said supported means by removing the marker from the effect of said retaining means.
Claim 2
Independent Claim 191 words
A device for supporting a marker or the like for printing on a surface at a particular location including: a base; means supported by said base for movement relative thereto; said base having means to releasably retain a marker on said supported means and adjacent said base; said supported means having a portion extending exteriorly of said base and cooperating with the marker to locate the marker exteriorly of said base and adjacent one end thereof; means to prevent rotation of the marker when the marker is on said supported means; means to locate the marker at the particular location on the surface for printing; said locating means extending longitudinally from the exterior portion of said supported means; means cooperating with said locating means to allow retraction of said locating means when said locating means is pressed against the surface so that the marker may be moved against the surface to print on the surface at the particular location; and means to produce relative movement between said supported means and said base to release the marker from said supported means by removing the marker from the effect of said retaining means.
Claim 3
Independent Claim 191 words
A device for supporting a marker or the like for printing on a surface at a particular location including: a base; means supported by said base for movement relative thereto; said base having means to releasably retain a marker on said supported means and adjacent said base; said supported means having a portion extending exteriorly of said base and cooperating with the marker to locate the marker exteriorly of said base and adjacent one end thereof; means to prevent rotation of the marker when the marker is on said supported means; means to locate the marker at the particular location on the surface for printing; said locating means extending longitudinally from the exterior portion of said supported means; means cooperating with said locating means to allow retraction of said locating means when said locating means is pressed against the surface so that the marker may be moved against the surface to print on the surface at the particular location; and means to produce relative movement between said supported means and said base to release the marker from said supported means by removing the marker from the effect of said retaining means.
Claim 4
Independent Claim 191 words
A device for supporting a marker or the like for printing on a surface at a particular location including: a base; means supported by said base for movement relative thereto; said base having means to releasably retain a marker on said supported means and adjacent said base; said supported means having a portion extending exteriorly of said base and cooperating with the marker to locate the marker exteriorly of said base and adjacent one end thereof; means to prevent rotation of the marker when the marker is on said supported means; means to locate the marker at the particular location on the surface for printing; said locating means extending longitudinally from the exterior portion of said supported means; means cooperating with said locating means to allow retraction of said locating means when said locating means is pressed against the surface so that the marker may be moved against the surface to print on the surface at the particular location; and means to produce relative movement between said supported means and said base to release the marker from said supported means by removing the marker from the effect of said retaining means.
