Abstract

A retaining and cutting device for positioning a leading edge of material at one end of a roll and for puncturing and severing the material a pre-determined distance from the leading edge after removing from the roll, the retaining device comprising elongated jaw members pivotally connected together, a closure member normally urging the jaw members together, and a cutter along one edge of at least one of the jaw members. Extensions of the jaw members are manually grasped to urge the jaw members into an open position for insertion of the next leading edge of material therebetween. The device may also be utilized as a cutting tool for opening sealed boxes and the like.

Claims

1. In a positioning device for holding and cutting material, comprising:

first and second elongated jaw members;

said first and second jaw members pivotally connected together including means for releasably gripping an edge of said material therebetween; and

a cutter along at least one edge of said jaw members.

2. In a positioning device according to claim 1 wherein at least one of said jaw members includes a frictional surface portion engageable with a surface of said material.

3. In a positioning device according to claim 1 wherein said gripping means includes a spring closure member having first and second extensions.

4. In a positioning device according to claim 1 wherein said elongated jaw members include first and second extension members.

5. In a positioning device according to claim 1 wherein said cutter is aligned along a distal end of at least one of said jaw members.

6. In a combination tool for maintaining separation of the leading edge of a material, puncturing and severing said material, the combination comprising:

elongated jaw members;

said jaw members having a spring closure member therebetween;

means for urging said jaw members into an open position; and

at least one of said jaw members having a frictional surface engageable with a surface of said material.

7. In a combination tool according to claim 6 wherein at least one of said jaw members includes means for cutting said material.

8. In a combination tool according to claim 7 wherein said cutting means includes a projection having at least one cutting edge.

9. In a combination tool according to claim 6 wherein said urging means include scissor-like grasping members.

10. In a combination tool according to claim 6 wherein said urging means are defined by a slightly upwardly extending member and an outwardly extending member located adjacent to said spring closure member.

11. In a combination tool according to claim 10 wherein said upwardly extending member is slightly concave and said outwardly extending member is defined by a depression extending perpendicular to said elongated jaw members.

12. In a combination tool according to claim 6 wherein said jaw members terminate in rounded ends.

13. In a combination tool for positioning and severing tape, the improvement comprising:

an elongated base member extending transversely of a roll of tape;

an upper member co-extensive with said base member;

said base member and said upper member having a hinge member located therebetween along a first end;

said first end including extension members; and

means extending along at least one of said base and upper members for cutting said tape.

14. In a combination tool according to claim 13 wherein at least one of said base or upper members includes a frictional surface.

15. In a combination tool according to claim 13 wherein said cutting means includes a member having at least one cutting surface.

16. In a combination tool according to claim 15 wherein said cutting surface extends outwardly along a horizontal plane.

17. In a combination tool according to claim 15 wherein said cutting surface is defined by a continuous beveled edge.

18. In a combination tool according to claim 13 wherein said cutting means includes a multi-tooth member.

19. In a method of retaining and cutting a leading end of material, having a combination tool with pivotally connected first and second members forming a jaw, engaging members extending from said first and second members, and a cutting member positioned along one of said first and second members, the method comprising the steps of:

applying manual pressure to said engaging members urging said first and second members into an open position;

positioning a leading edge of the material along an upper surface of said second member; and

releasing said engaging members, thereby placing said first and second members into a closed position.

20. In the method according to claim 19 wherein one of said first and second members includes means for cutting.

21. In the method according to claim 19 wherein said steps further include removing the leading edge of the material from said combination tool, pulling the leading edge of the material away from a roll and placing a desired length of the material along a member to be secured.

22. In the method according to claim 20 including re-positioning said first and second members to grasp said material and piercing the material with said cutting means.

23. In the method according to claim 19 further including positioning said tool along a surface of a length of material secured on an item, applying pressure along a surface of said first member thereby piercing the surface of the material and urging said tool along a desired length of the material.
