Abstract
Abstract A stenciling apparatus for the marking of identification indicia on vehicles and the like having a casing accommodating a housing incorporating the convergence of means for compressed air supply delivery means for stencil medium pickup and means for stencil medium delivery to the surface to be marked, the casing having an elongated front portion and a lower forward wall casing portion extending rearward at a downward incline and then curving abruptly downward and forward meeting a rear wall casing forming a cusp which acts as a stencil medium holding area and a substantially cubical stencil holding unit having at least one aperture for receipt of a stencil and an elongated v-shaped notch member upon the top surface of the stencil holding unit to mate and overlay a corresponding elongated v-shaped notch upon a top front surface of the stencil unit casing.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
232 words
An improved casing for a stenciling apparatus of the type containing a stenciling medium therein to be delivered by means of a compressed air stream to a surface to be marked having the upper rear portion of the casing adapted to accommodate therein a housing incorporating the convergence of means for compressed air supply delivery, means for stencil medium pickup and means for stencil medium delivery to said surface, said casing having a forward portion formed by an upper surface sidewall, a bottom surface sidewall and a pair of sidewalls all forming at said forward portion a substantially rectangular aperture aligned to oppose said rear portion of said casing and the stenciling medium delivery means wherein the improvement comprises: said bottom surface sidewall extending from said rectangular aperture rearward at an incline and at a position below said housing curving abruptly downward and then forward at its lower extent; a lower rear sidewall extending from the upper rear portion of said casing downward in a forwardly bowed curve meeting said bottom surface sidewall; and said pair of surface sidewalls extending downward meeting said bottom surface sidewall and said lower surface sidewall forming an improved stenciling medium recycling and holding area in the shape of a forwardly extending cusp in order to better retain said stenciling medium in said holding and recycling area when the stenciling apparatus is used in a vertical position.
Claim 2
Dependent Claim
232 words
An improved casing for a stenciling apparatus of the type containing a stenciling medium therein to be delivered by means of a compressed air stream to a surface to be marked having the upper rear portion of the casing adapted to accommodate therein a housing incorporating the convergence of means for compressed air supply delivery, means for stencil medium pickup and means for stencil medium delivery to said surface, said casing having a forward portion formed by an upper surface sidewall, a bottom surface sidewall and a pair of sidewalls all forming at said forward portion a substantially rectangular aperture aligned to oppose said rear portion of said casing and the stenciling medium delivery means wherein the improvement comprises: said bottom surface sidewall extending from said rectangular aperture rearward at an incline and at a position below said housing curving abruptly downward and then forward at its lower extent; a lower rear sidewall extending from the upper rear portion of said casing downward in a forwardly bowed curve meeting said bottom surface sidewall; and said pair of surface sidewalls extending downward meeting said bottom surface sidewall and said lower surface sidewall forming an improved stenciling medium recycling and holding area in the shape of a forwardly extending cusp in order to better retain said stenciling medium in said holding and recycling area when the stenciling apparatus is used in a vertical position.
Claim 3
Dependent Claim
17 words
The stenciling apparatus casing of claim 1 having means to affix stencils over said frontal casing aperture.
Claim 4
Dependent Claim
84 words
The stenciling apparatus of claim 2 wherein the means of affixing said stencils comprises: a stencil holding unit having at least one substantially rectangular aperture defined within its front surface and four perpendicularly abutting sides to mate with said forward portion of said casing in an overlying relationship; a casing v-shaped notch member upon the upper sidewall surface of said casing; and a v-shaped notch upon the upper of said sides of said stencil holding unit to mate and overlay said casing v-shaped notch.
Claim 5
Dependent Claim
63 words
The apparatus as recited in claim 3 further including at least one stencil member to be removably affixed within said frontal aperture of said stencil holding unit; and wherein said stencil comprises a substantially rectangular member having two end portions in the same plane and a middle portion raised out of the plane of said end portions and having an indicia aperture therethrough.
Claim 6
Dependent Claim
35 words
The apparatus as recited in claim 4 wherein said housing is affixed within said casing to allow limited pivotal lateral movement of said stenciling medium delivery means to direct said medium horizontally across said stencils.
