Abstract
A manually operable device that is used to cut a synthetic material and also singe the end of this newly cut material to prevent it from unravelling. This tool incorporates a separate crimping assembly, cutting assembly, and burning assembly for each of these steps. The crimping assembly holds the material in place during the cutting and burning stages and also aids in fusing the melted ends of the material into a uniform mass. The cutting assembly cuts the material where desired, trims any stray fibers from the cut and/or fused end, and also removes any excess burn from this fused end. The burning assembly, connected to a reservoir, burns a flammable fluid so as to burn or singe the material placed thereover.
Claims12
A hand tool comprising:
- (a) first and second elongated handles pivotally secured together at one end region and thereby defining a working end adjacent said one end region, wherein the end of said first and second elongated handles opposite said working end are enlarged and constructed for grasping by the user, said enlarged end of said first elongated handle opposite said working end comprising an opening constructed and arranged for the insertion therethrough of a user's finger or thumb and, said enlarged end of said second handle opposite said working end comprising reservoir means for containing or storing a flammable fluid therein;
- (b) crimping means forming a part of said working end for crimping a material placed therein, said crimping means comprising a pair of oppositely positioned crimps or die which are brought or biased together by the pivoting of said first and second elongated handles, said oppositely positioned crimps or die each being symmetrically notched and, further comprising a plurality of matching notches that are differently sized such that when said crimping means are in the closed position with said crimps or die abutting each other, differently sized openings through said crimps or die are created;
- (c) cutting means forming a part of said working end for cutting a material placed therein;
- (d) burning means projecting into said working end for burning or singeing a material placed therein;
- and,
- (e) control means for controlling the operation of said burning means, whereby a material placed within said working end can be sequentially crimped and held in place by said crimping means, trimmed by said cutting means, melted or singed by said burning means and fused together by repeated manipulation within said crimping means.
A method of cutting and singeing a strand of synthetic material comprising the steps of:
- (a) positioning the synthetic material within a working end of a hand tool, said working end of said hand tool comprising:
- i. crimping means for crimping the material placed therein;
- ii. cutting means for cutting the material placed therein;
- iii. burning means for burning or singeing the material placed thereover;
- and,
- iv. control means for controlling the operation of said burning means;
- (b) crimping the material by said crimping means thereby restraining the material in place within said working end;
- (c) cutting the material extending within said cutting means;
- (d) burning or singeing the newly cut end of the material via said burning means;
- (e) controlling the operation of said burning means by said control means;
- (f) crimping the material between a pair of oppositely positioned crimps or die which are constructed with at least one pair of symmetrical notches therein;
- and,
- (g) containing or storing a flammable fluid within a reservoir, said reservoir forming a part of and secured to said hand tool.
