Abstract
Abstract The disclosure relates to a hand held masking machine which is used for masking various surfaces adjacent to which paint is to be applied, as for example the machine may be used on a wall adjacent a ceiling so that the ceiling may be painted without contacting the adjacent wall with a brush or overlapping with spray paint. The hand held masking machine in accordance with the present disclosure is provided with a frame having offset portions holding a tape roll holder and a paper roll holder with their ends offset so that the tape is dispensed in such a manner that part of the tape adheres to the paper on the roller and the rest of the tape overlaps the paper beyond the edge of the paper roll and beyond the edge of the paper dispensed therefrom. The paper and tape is dispensed in adhered relation to each other and the tape is then adhesively engaged with a surface to which it is applied and, following this, the machine is moved with the tape and the paper in tension which pulls the paper and tape from the machine in adhesively connected relationship and a guide bar on the forward portion of the frame wipes the adhesive tape securely into adhesive relation with the surface being applied as the machine is moved along said surface.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
255 words
In a hand held masking machine: a frame; a rotary tape roll holder rotatably mounted on said frame; an elongated rotary paper roll holder rotatably mounted on said frame; said paper roll holder having a rotary axis and first and second ends; an elongated paper guide bar mounted on said frame in substantially parallel spaced relation to said rotary axis of said paper roll holder; said tape roll holder having a rotary axis generally parallel to said rotary axis of said paper roll holder; said tape roll holder having an end portion; said first end of said paper roll holder disposed in spaced overlapping relation to said end portion of said tape roll holder; whereby an edge of tape dispensed from said tape roll holder is spaced from and overlaps an edge of said paper disposed substantially in alignment with said first end portion of said paper roll holder; said frame having first and second offset portions adjacent to which said end portion of said tape roll holder and said first end of said paper roll holder respectively are disposed; a manually holdable handle on said frame; said handle spaced from said first offset portion of said frame in a direction toward which said end portion of said tape roll holder is directed; whereby said tape roll holder may be operated in close proximity to a building room corner or the like with said handle disposed substantially spaced therefrom; said paper roll holder extending from said second offset portion of said frame in said direction.
Claim 2
Dependent Claim
255 words
In a hand held masking machine: a frame; a rotary tape roll holder rotatably mounted on said frame; an elongated rotary paper roll holder rotatably mounted on said frame; said paper roll holder having a rotary axis and first and second ends; an elongated paper guide bar mounted on said frame in substantially parallel spaced relation to said rotary axis of said paper roll holder; said tape roll holder having a rotary axis generally parallel to said rotary axis of said paper roll holder; said tape roll holder having an end portion; said first end of said paper roll holder disposed in spaced overlapping relation to said end portion of said tape roll holder; whereby an edge of tape dispensed from said tape roll holder is spaced from and overlaps an edge of said paper disposed substantially in alignment with said first end portion of said paper roll holder; said frame having first and second offset portions adjacent to which said end portion of said tape roll holder and said first end of said paper roll holder respectively are disposed; a manually holdable handle on said frame; said handle spaced from said first offset portion of said frame in a direction toward which said end portion of said tape roll holder is directed; whereby said tape roll holder may be operated in close proximity to a building room corner or the like with said handle disposed substantially spaced therefrom; said paper roll holder extending from said second offset portion of said frame in said direction.
Claim 3
Dependent Claim
53 words
The invention as defined in claim 1, wherein: a roll of paper having opposite ends is disposed on said paper roll holder; and said handle is disposed in a position generally between opposite ends of a roll of paper disposed on said paper roll holder; said roll of paper having a peripheral portion.
Claim 4
Dependent Claim
112 words
The invention as defined in claim 2, wherein: a roll of tape is disposed on said tape roll holder; said roll of tape having a peripheral portion; said tape extending from said peripheral portion and having an adhesive side disposed in a direction facing inwardly toward said rotary axis of said tape roll holder whereby, when said tape is pulled and adhesively separated from said peripheral portion, adhesive tension tends to force said adhesive side of said tape toward said peripheral portion of said roll of paper as said tape is pulled therefrom, thus making adhesive contact with said peripheral portion of said roll of paper as the paper is dispensed therefrom.
Claim 5
Dependent Claim
89 words
The invention as defined in claim 3, wherein: said tape and paper are adhesively secured together with said tape overlapping said paper and whereby said tape may be adhesively secured to a surface being masked with said paper whereupon tension applied to said tape by movement of said frame unrolls and dispenses the tape and paper onto said surface; said guide bar being disposed to be pressed and wiped against said tape and paper to insure adhesion of said tape to said surface as said frame is moved thereover.
Claim 6
Dependent Claim
45 words
The invention as defined in claim 4, wherein: a resiliently located friction means is carried by said frame and disposed to frictionally and resiliently bear upon said peripheral portion of said roll of paper to insure even dispensation thereof relative to dispensation of said tape.
Claim 7
Dependent Claim
57 words
The invention as defined in claim 1, wherein: said paper roll holder is disposed between said tape roll holder and said guide bar; said guide bar having an elongated convex surface disposed to engage paper and tape adhesively secured thereto so as to force said adhesive side of said tape into contact with a surface being masked.
Claim 8
Dependent Claim
58 words
The invention as defined in claim 6, wherein: said guide bar is removeably coupled to said frame and longitudinally adjustable in a direction parallel with said rotary axes so as to accommodate tape of varying widths which may extend varying distances from an edge of said paper to which said tape is adhesively secured and overlapped relative thereto.
Claim 9
Dependent Claim
31 words
The invention as defined in claim 6, wherein: said guide bar is provided with a cut off edge disposed to cut off paper and tape when a masking operation is completed.

The invention as defined in claim 1, wherein: said masking machine is provided with a forward portion and a rearward portion; said manually holdable handle being elongated and having an end portion extending toward said rearward portion of said masking machine.
Claim 12
Dependent Claim
32 words
The invention as defined in claim 10, wherein: said paper roll holder is in a position which is disposed forwardly toward said forward portion of said masking machine relative to said handle.
Claim 13
Dependent Claim
