Abstract

A strip of pressure sensitive tape is laid out along top and bottom plates or top and bottom tracks of a wall that is to be constructed with studs at a fixed spacing. The tape bears stud location marks at preselected intervals for ease in locating the studs for connection to the top and bottom plates and top and bottom tracks. The tape is provided in a supply roll that is rotatably mounted in an applicator tool having a handle and a pressure roller that enable the tape to be pressed against the plate or track and withdrawn from the roll as the tool and tape are moved along. To facilitate locating and positioning of the end of the tape, and therefore of the first stud location mark of the tape, the tool is provided with a pressure foot extending from the pressure roller and has an edge which may easily be positioned at the desired starting point of the tape, as, for example, against an existing wall. Means are provided to hold the end of the tape against the pressure foot with a first stud location mark at the pressure foot end for initial positioning of the tape.

Claims

1. A method for marking locations of building elements in a wall of a building, comprising the steps of:

providing a roll of tape having adhesive on one side and a plurality of locating marks on the other side,

mounting the tape roll in a tape applicator having a pressure foot extending therefrom,

positioning the tape on one side of the pressure foot with an outer most end of the pressure foot at a known distance from one of said locating marks of the tape,

said step of positioning the tape on one side of said pressure foot comprising withdrawing tape from said roll until said one locating mark is aligned with said pressure foot end, holding the end of said tape at said pressure foot end, and severing the tape at said pressure foot end,

positioning the pressure foot end adjacent a member to be marked at a start position on said member that is a known distance from a desired first building element location,

pressing the tape against said member adjacent said start position to secure a leading portion of the tape to the member with said one locating mark at a known distance from said first location,

moving the applicator along said member, and

withdrawing tape from the roll as the applicator is moved, while pressing the tape against said member.

2. The method of claim 1 including the step of releasing the tape from said pressure foot end.

3. The method of claim 1 including the step of retracting the pressure foot and releasing the tape from said pressure foot end.

12. The apparatus of claim 1 including latch means for holding said bracket in an outer position displaced from said body, spring means for urging the bracket to a folded position adjacent said body, said first mentioned means including means for releasing the holding of said bracket in outer position in response to a force exerted on the pressure foot.

4. Apparatus for laying out locations of studs for a building, which studs are to be secured with one end thereof adjacent a structural member having a stud location start position, said apparatus comprising:

a tape applicator body,

a roll of tape rotatably mounted to said body, said tape having a plurality of location marks on one side mutually spaced by predetermined distances, and having adhesive on the other side,

a pressure foot secured to said body and having a locating end,

means for guiding an end of said tape to the pressure foot with an edge of one of said location marks of the tape positioned at said pressure foot locating end, whereby said pressure foot end may be positioned at said location start position to thereby position said one location mark of the tape at said location start position, and

means for releasably holding an end of said tape against the pressure foot adjacent said pressure foot locating end.

5. The apparatus of claim 4 including means responsive to pressure exerted on the pressure foot for retracting the pressure foot and releasing the tape from the pressure foot.

6. The apparatus of claim 4 including means on the pressure foot locating end for cutting said tape at said locating end.

7. Apparatus for laying out locations of studs for a building, which studs are to be secured with one end thereof adjacent a structural member having a stud location start position, said apparatus comprising:

a tape applicator body,

a roll of tape rotatably mounted to said body, said tape having a plurality of location marks on one side mutually spaced by predetermined distances, and having adhesive on the other side,

a pressure foot secured to said body and having a locating end, and

means for guiding an end of said tape to the pressure foot with an edge of one of said location marks of the tape positioned at said pressure foot locating end, whereby said pressure foot end may be positioned at said location start position to thereby position said one location mark of the tape at said location start position,

said means for guiding comprising a power roller rotatably mounted on said body, and means responsive to said power roller for withdrawing tape from said roll of tape and feeding withdrawn tape to said power roller, whereby tape entrained over said power roller is guided and driven to said pressure foot.

8. Apparatus for laying out locations of studs for a building, which studs are to be secured with one end thereof adjacent a structural member having a stud location start position, said apparatus comprising:

a tape applicator body,

a roll of tape rotatably mounted to said body, said tape having a plurality of location marks on one side mutually spaced by predetermined distances, and having adhesive on the other side,

a pressure foot secured to said body and having a locating end, and

means for guiding an end of said tape to the pressure foot with an edge of one of said location marks of the tape positioned at said pressure foot locating end, whereby said pressure foot end may be positioned at said location start position to thereby position said one location mark of the tape at said location start position,

said means for guiding including a power/pressure roller rotatably mounted to said applicator body and having a peripheral edge projecting from the applicator body for frictional engagement with said structural member to cause said roller to be rotated as the applicator body is moved along a contacting surface of such member with the roller in contact with said surface, a tape drive roller rotatably mounted in the body, a driving connection between said power/pressure roller and said tape drive roller, means coupled with the tape drive roller for withdrawing tape from said supply roll, and means on said body for severing the tape.

9. The apparatus of claim 8 including means on the end of said pressure foot for severing said tape at said pressure foot end.

10. The apparatus of claim 8 wherein said pressure foot is mounted to said body for motion between extended and retracted positions, and including over center spring means for releasably holding said pressure foot in each of said positions.

11. The apparatus of claim 8 wherein said pressure foot includes a bracket secured to the pressure foot and pivotally connected to said applicator body for motion between extended and retracted positions, means adjacent said pressure foot end for holding an end of the tape against an outer surface of the pressure foot in extended position, and means for moving the bracket to retracted position and releasing the tape end from the pressure foot.

13. Apparatus for laying out a series of positions to locate ends of a plurality of studs that will form a structural wall or the like, said apparatus comprising:

an applicator housing,

a power roller rotatably mounted to the housing and having a peripheral edge portion protruding therefrom,

a primary tape drive roller rotatably mounted in the housing,

a driving connection between the power roller and the tape drive roller,

a secondary drive roller rotatably mounted in the housing,

spring means for urging the drive rollers toward each other,

a tape supply roll rotatably mounted in the housing and carrying a roll of tape, said tape having adhesive on one side thereof and a plurality of stud location marks on the other side thereof, said tape extending between said drive rollers to be driven thereby,
