Abstract

Abstract The concept pertains to a decorative item such as an artificial Christmas tree, shrubbery, brushes or the like of a permanent or knockdown type. The branches or limbs are unique in that the imitation needles are obliquely angled and slanted toward the outward end of the stem-like core. Each branch comprises a core of intertwisted core wires and complemental pliant thermoplastic bristles which define imitation needles distributively arranged lengthwise of the core and having median portions nested and retentively clenched between the twisted convolutions of the wires and outwardly flaring half portions slanting away from the core and toward the outward end thereof. The branch or brush is formed with slanting bristles by insertion into a sleeve of lesser diameter than the brush to angle the bristles with the core wires then being heated to reset the thermoplastic plastic bristles so that the portions of the bristles outwardly of the core will be set at an oblique angle.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 161 words
IN COMBINATION, A TUBULAR HAVING MEMBERS UNOBSTRUCTED INLET AND OUTLET ENDS, AN INSERTABLE AND REMOVABLE PREFABRICATED SELF-CONTAINED BRUSH, SAID BRUSH COMPRISING AN ELONGATED STEM-LIKE MADE UP OF A PAIR OF LIKE INTERWISTED CORE WIRES AND COMPLEMENTAL PLIANT BRISTLES OF THERMOPLASTIC PLASTIC MATERIAL WHICH HAVE MEDIAN PORTIONS NESTED AND RETENTIVELY CLENCHED BETWEEN THE TWISTED CONVOLUTIONS OF SAID CORE WIRES, THE DIAMETER OF THE TUBULAR MEMBER BEING LESS THAN THE BRUSH WHEREBY FLEXIBLE BRISTLE HALF-PORTIONS PROJECTING RADIALLY FROM THE LOCALE OF SAID CORE WILL BE OBLIQUELY ANGLED WHEN THE BRUSH IS INSERTED THROUGH THE TUBULAR MEMBER, AND ELECTRIC CURRENT CONDUCTING WIRES CONNECTED TO THE END PORTIONS OF THE CORE WIRES OUTWARDLY OF THE ENDS OF THE TUBULAR MEMBER FOR HEATING SAID CORE WIRES AND SUBJECTING THE CLENCHED MEDIAN PORTIONS OF SAID BRISTLES TO HEAT AND CAUSING THE SAME TO BE RESET WHILE OBLIQUELY ANGLED AND IN SO DOING SETTING THE HALF-PORTIONS WITH A SLANT FROM THE CORE TOWARD ONE END OF SAID CORE.
Claim 2
Dependent Claim 161 words
IN COMBINATION, A TUBULAR HAVING MEMBERS UNOBSTRUCTED INLET AND OUTLET ENDS, AN INSERTABLE AND REMOVABLE PREFABRICATED SELF-CONTAINED BRUSH, SAID BRUSH COMPRISING AN ELONGATED STEM-LIKE MADE UP OF A PAIR OF LIKE INTERWISTED CORE WIRES AND COMPLEMENTAL PLIANT BRISTLES OF THERMOPLASTIC PLASTIC MATERIAL WHICH HAVE MEDIAN PORTIONS NESTED AND RETENTIVELY CLENCHED BETWEEN THE TWISTED CONVOLUTIONS OF SAID CORE WIRES, THE DIAMETER OF THE TUBULAR MEMBER BEING LESS THAN THE BRUSH WHEREBY FLEXIBLE BRISTLE HALF-PORTIONS PROJECTING RADIALLY FROM THE LOCALE OF SAID CORE WILL BE OBLIQUELY ANGLED WHEN THE BRUSH IS INSERTED THROUGH THE TUBULAR MEMBER, AND ELECTRIC CURRENT CONDUCTING WIRES CONNECTED TO THE END PORTIONS OF THE CORE WIRES OUTWARDLY OF THE ENDS OF THE TUBULAR MEMBER FOR HEATING SAID CORE WIRES AND SUBJECTING THE CLENCHED MEDIAN PORTIONS OF SAID BRISTLES TO HEAT AND CAUSING THE SAME TO BE RESET WHILE OBLIQUELY ANGLED AND IN SO DOING SETTING THE HALF-PORTIONS WITH A SLANT FROM THE CORE TOWARD ONE END OF SAID CORE.
Claim 3
Independent Claim 79 words
The method of fabricating an artificial branch having a plurality of thermoplastic needles extending transversely to a twisted wire pair and held therebetween by frictional engagement which consists of the steps of deflecting the needles longitudinally of the wires, heating the wires by passing electric current therethrough to soften the needles held therebetween and maintaining the needles in deflected position while electric current passes through the wires and until the needles are cooled and reset in their deflected position.
Claim 4
Independent Claim 79 words
The method of fabricating an artificial branch having a plurality of thermoplastic needles extending transversely to a twisted wire pair and held therebetween by frictional engagement which consists of the steps of deflecting the needles longitudinally of the wires, heating the wires by passing electric current therethrough to soften the needles held therebetween and maintaining the needles in deflected position while electric current passes through the wires and until the needles are cooled and reset in their deflected position.
Claim 5
Dependent Claim 49 words
The method as defined in claim 2 wherein the step of deflecting the needles includes the step of passing the twisted wire pair and needles through means to deflect said needles at a predetermined angle to the axis of said wires prior to passing electric current through the wires.
Claim 6
Dependent Claim 191 words
Apparatus for fabricating artificial branches consisting of a pair of central wires twisted together to frictionally hold a plurality of short thermoplastic needles positioned between said wires comprising means to bend said needles at a predetermined angle to said wires and means to heat said wires to sufficiently soften said needles by heat transfer from said wires to said needles, said heating means including electric conducting wires connected to the central wires at longitudinally spaced ends to pass electricity through the central wires for heating the central wires, said means to bend said needles including a tubular member having an unobstructed inlet end and an unobstructed outlet end at a substantially uniform internal bore of less diameter than the needles for deflecting the needles when the branch is inserted longitudinally through the tubular member, said electric wires being connected to the central wires outwardly of the inlet end and outlet end of the tubular member thereby requiring the needles to be bent to a predetermined angle prior to heating of the central wires and requiring disconnection of the electric conducting wires prior to removal of the branch from the tubular member.
Claim 7
Dependent Claim 191 words
