Abstract
Abstract A tape and paper dispensing apparatus which has a C-shaped tubular frame and handle combination to which are also mounted a bracket for the tape and paper roller drums and a bracket for the cutting blade. The frame doubles as a handle and is made more stable by the placement of a thumbrest bracket on the tubular handle/frame. A depressor bar is spring biased to contact the point of adhesion of the tape to the paper on the paper roll and has a pressure applying foot which assists in insuring proper adhesion. The position of the end of the paper roller drum relative to a tape dispensing path is adjustable.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
A masking paper and tape dispensing machine comprising: a. an elongate curved frame member including i. a first end, ii. a second end, and iii. a central hand grip comprised of an integral portion of said curved frame intermediate said first and second ends; b. a roller mounting bracket carried proximate one of the ends of said frame member; c. a paper roller drum carried by said mounting bracket for rotation about an axis of rotation; d. a tape roller drum carried by said mounting bracket for rotation about an axis of rotation, said tape roller drum being positioned such that the dispensing path of a roll of tape mounted upon said tape roller drum is generally aligned with one end of said paper roller drum; e. a blade mounting bracket carried proximate the other of the ends of said frame member; and f. a blade carried by said blade mounting bracket and having a cutting edge.
Claim 2
Dependent Claim
157 words
A masking paper and tape dispensing machine comprising: a. an elongate curved frame member including i. a first end, ii. a second end, and iii. a central hand grip comprised of an integral portion of said curved frame intermediate said first and second ends; b. a roller mounting bracket carried proximate one of the ends of said frame member; c. a paper roller drum carried by said mounting bracket for rotation about an axis of rotation; d. a tape roller drum carried by said mounting bracket for rotation about an axis of rotation, said tape roller drum being positioned such that the dispensing path of a roll of tape mounted upon said tape roller drum is generally aligned with one end of said paper roller drum; e. a blade mounting bracket carried proximate the other of the ends of said frame member; and f. a blade carried by said blade mounting bracket and having a cutting edge.
Claim 3
Dependent Claim
77 words
The machine of claim 1, further including: a. a depressor bar pivotally mounted on said roller mounting bracket and having a pressure applying foot extending across the tape dispensing path; and b. biasing means for urging the pressure applying foot into contact with tape dispensed from said tape roll in the region of contact between the tape and the surface of a sheet of paper rolled in a roll of paper mounted on said paper roller drum.
Claim 4
Dependent Claim
22 words
The machine of claim 1, further including adjustment means for selectively positioning said paper roller drum along the axis of rotation thereof.
Claim 5
Dependent Claim
90 words
The apparatus of claim 3, wherein the mounting of the paper roller drum to the roller mounting bracket further comprises: a shaft of a greater length than the paper roller drum; a coil spring positioned between the paper roller drum and the bracket, urging the paper roller drum away from the bracket; and a selectively adjustable stop member operatively connected to the shaft to form a selectively adjustable stop which selectively adjusts the distance to which the coil spring urges the paper roller drum away from the roller mounting bracket.
Claim 6
Dependent Claim
34 words
The machine of claim 1, further including: a thumbrest bracket attached to the frame in a position to receive the thumb of a user grasping the frame by the hand grip of the frame.
Claim 7
Dependent Claim
56 words
The machine of claim 1, wherein said roller mounting bracket includes: a. a first leg extending in a direction toward said other of the ends of said frame bracket and carrying said paper roller drum; and b. a second leg extending in a direction generally opposite from said first leg and carrying said tape roller drum.
Claim 8
Dependent Claim
38 words
The machine of claim 6, wherein the axis of rotation of said paper roller drum extends from said roller mounting bracket laterally of said frame member and through an opening formed by the curve of said frame member.
Claim 9
Dependent Claim
34 words
The machine of claim 7, wherein the axis of rotation of said tape roller drum and the cutting edge of said blade are aligned with the axis of rotation of said paper roller drum.
