Abstract
Abstract A system for fastening at least a pair of plies of fabric together utilizing a helical member having body portion of a certain pitch. The helical member also includes a sharpened tip and an end portion with a loop which lies in a plane which intersects the helical path of the helical member. A tool constructed with a gripping portion and a hollow portion connected to the same is employed to turn the helical member through the adjacent plies of fabric. The hollow portion is provided with a helical surface which is intended to contact the helical member. The pitch of the helical surface of the hollow member is opposite to that of the helical member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
99 words
A system for removably holding at least a pair of fabric plies together comprising: a. a helical member, tracing a helical path at a certain pitch, said helical member having a first end including a sharpened tip and a second end with a loop portion lying in a plane intersecting the helical path; and b. a tool including a gripping portion and a hollow portion connected to said gripping portion, said hollow portion including a helical surface intended to contact the helical member, said pitch of said helical surface being the opposite of said pitch of said helical member.
Claim 2
Independent Claim
99 words
A system for removably holding at least a pair of fabric plies together comprising: a. a helical member, tracing a helical path at a certain pitch, said helical member having a first end including a sharpened tip and a second end with a loop portion lying in a plane intersecting the helical path; and b. a tool including a gripping portion and a hollow portion connected to said gripping portion, said hollow portion including a helical surface intended to contact the helical member, said pitch of said helical surface being the opposite of said pitch of said helical member.
Claim 3
Dependent Claim
22 words
The system of claim 1 in which said loop portion of said second end of said helical member is a closed loop.
Claim 4
Dependent Claim
41 words
The system of claim 2 in which said sharpened tip of said first end of said helical member includes a first portion extending along said helical path, and a second helical portion joining said first portion to form said sharpened tip.
Claim 5
Dependent Claim
20 words
The system of claim 2 in which said tool gripping portion includes a flange extending outwardly from said hollow portion.
