Abstract
Abstract A portable tape dispenser for dispensing dry wall tape comprises a hopper for containing a supply of dry wall joint cement in fluid form and means serving to support the hopper from the waist of a workman in a manner freeing both of his hands. A roll of dry wall joint tape is carried and supported for rotation from the hopper whereby guide means lead the tape from its roll into and out of the supply of joint cement. A dispensing slot is formed between a stationary knife edge member and a movable knife edge member spaced therefrom to receive the tape therebetween. The two knife edge members serve to remove cement from opposite sides of the tape. However, the spacing between the edges serves to permit one of the two edges to leave a coating of cement of predetermined thickness when the tape is withdrawn across the other knife edge member. A comb element is disposed in conjunction with one of the knife edge members so that the coating of cement applied to the tape will extend in spaced longitudinal lines. A trowel cleaning chute extends along the outer edge of the hopper.

Total Claims: 13
Claim 1
Independent Claim
238 words
A portable tape dispenser comprising a hopper for containing a supply of dry wall joint cement in fluid form, means serving to support said hopper from the waist of a workman, means in said hopper loosely carrying a roll of pliable tape of a type to be cemented along a joint between dry wall sections, means disposed in said hopper and including means forming a tape dispensing slot for passing the tape therethrough, means between said slot and said roll for immersing a portion of the length of tape therebetween into the cement in said hopper to coat both sides of the tape with cement, said slot having first and second edges in opposed relation to respectively confront the ''''front '''' and ''''back'''' surfaces of the tape, as disposed along a dry wall joint, said first edge being disposed to wipe substantially all cement from said ''''front'''' surface as said tape is drawn across said first edge, the spacing between said edges being sufficient to cause said second edge to remove all but a predetermined thickness of cement from said ''''back'''' surface as the tape is drawn between said edges while riding in contact across said first edge thereby metering the thickness of the coating applied to said ''''back'''' surface and said slot forming means being mounted on a pivotable frame whereby said slot means is reversible with respect to the front and rear portions of said hopper.

A portable tape dispenser comprising a hopper for containing a supply of dry wall joint cement in fluid form, means serving to support said hopper from the waist of a workman, means in said hopper loosely carrying a roll of pliable tape of a type to be cemented along a joint between dry wall sections, means disposed in said hopper and including means forming a tape dispensing slot for passing the tape therethrough, means between said slot and said roll for immersing a portion of the length of tape therebetween into the cement in said hopper to coat both sides of the tape with cement, said slot having first and second edges in opposed relation to respectively confront the ''''front '''' and ''''back'''' surfaces of the tape, as disposed along a dry wall joint, said first edge being disposed to wipe substantially all cement from said ''''front'''' surface as said tape is drawn across said first edge, the spacing between said edges being sufficient to cause said second edge to remove all but a predetermined thickness of cement from said ''''back'''' surface as the tape is drawn between said edges while riding in contact across said first edge thereby metering the thickness of the coating applied to said ''''back'''' surface and said slot forming means being mounted on a pivotable frame whereby said slot means is reversible with respect to the front and rear portions of said hopper.
Claim 3
Dependent Claim
51 words
A portable tape dispenser according to claim 1 further comprising a chute leading to said hopper and having an elongated upper edge disposed at the side of the workman and adapted to permit a trowel to be scraped thereacross to remove and return excess cement to said hopper from the trowel.
Claim 4
Dependent Claim
44 words
In a portable tape dispenser for dry wall joint tape according to claim 1 wherein said dispensing slot is disposed below and adjacent to an edge of said hopper to catch dripping of the coated side of said tape when withdrawn via said slot.
Claim 5
Dependent Claim
187 words
A portable tape dispenser comprising a hopper for containing a supply of dry wall joint cement in fluid form, means serving to support said hopper from the waist of a workman in a manner freeing both of his hands, means for carrying a length of dry wall joint tape wrapped to form a roll thereof and supported for rotation, guide means for leading the tape from its roll into and out of the supply of joint cement, a dispensing slot formed between first and second knife edge members spaced to receive the tape therebetween and disposed transversely of said tape as the tape is drawn from said supply, said first and second edges serving to remove cement from opposite sides of the tape, the spacing between said edges serving to permit said second edge to leave a coating of cement of predetermined thickness when said tape is withdrawn via said slot while passing in contact over said first edge, and said knife edge members being mounted on a pivotable frame whereby said slot means is reversible with respect to the front and rear portions of said hopper.
Claim 6
Dependent Claim
187 words
A portable tape dispenser comprising a hopper for containing a supply of dry wall joint cement in fluid form, means serving to support said hopper from the waist of a workman in a manner freeing both of his hands, means for carrying a length of dry wall joint tape wrapped to form a roll thereof and supported for rotation, guide means for leading the tape from its roll into and out of the supply of joint cement, a dispensing slot formed between first and second knife edge members spaced to receive the tape therebetween and disposed transversely of said tape as the tape is drawn from said supply, said first and second edges serving to remove cement from opposite sides of the tape, the spacing between said edges serving to permit said second edge to leave a coating of cement of predetermined thickness when said tape is withdrawn via said slot while passing in contact over said first edge, and said knife edge members being mounted on a pivotable frame whereby said slot means is reversible with respect to the front and rear portions of said hopper.
Claim 7
Dependent Claim
