Abstract
Abstract A machine for making artificial limbs as for a Christmas tree where twisted wires having simulated needles attached are fed by a reciprocating transverse action to a pair of cutters which cut the wires to predetermined lengths while at the same time a pair of wires and a strand of decorative material are fed between a pair of pulleys where the cut lengths are attached perpendicularly to the pair of wires and decorative strand being twisted.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A machine for making artificial limbs comprising first means for feeding twisted wires with simulated needles therein, second means for feeding wires and decorative material, said first means feeding the twisted wires with simulated needles between the wires fed from said second means, a pulley means receiving said wires and decorative material from said second means, a pair of spaced cutters receiving said wires with simulated needles from said first means, means to hold and twist said wires and decorative material, with cut lengths of said wires with simulated needles disposed between twisted wires of said wires and decorative material, said pulley means positioning said wires with simulated needles substantially perpendicularly to said wires with decorative material for attachment to said twisted wires and decorative material.
Claim 2
Dependent Claim
126 words
A machine for making artificial limbs comprising first means for feeding twisted wires with simulated needles therein, second means for feeding wires and decorative material, said first means feeding the twisted wires with simulated needles between the wires fed from said second means, a pulley means receiving said wires and decorative material from said second means, a pair of spaced cutters receiving said wires with simulated needles from said first means, means to hold and twist said wires and decorative material, with cut lengths of said wires with simulated needles disposed between twisted wires of said wires and decorative material, said pulley means positioning said wires with simulated needles substantially perpendicularly to said wires with decorative material for attachment to said twisted wires and decorative material.
Claim 3
Dependent Claim
24 words
The machine of claim 1, further characterized by said firs means mounted for transverse movement reciprocating past each of said spaced cutters in turn.
Claim 4
Dependent Claim
24 words
The machine of claim 1, further characterized by each of said cutters including sliding elements, and cam means controlling movement of said sliding elements.
Claim 5
Dependent Claim
32 words
The machine of claim 3, further characterized by said sliding elements including a set of at least three elements positioned to move toward and away from a set of three similar elements.
Claim 6
Dependent Claim
70 words
The machine of claim 4, further characterized by a first one of each of said sets of elements having a notch means to bend an end of said wire with simulated needles at an angle of 90° to said last mentioned wire, a second one of each of said sets of elements having a notch means to complete the bend of said last mentioned wires to substantially a 180° bend.
Claim 7
Dependent Claim
39 words
The machine of claim 1, further characterized by air cylinder operated cutting means positioned along said twisted wires and decorative material after said pulley means to cut said twisted wires and decorative material upon completion of an artificial limb.
Claim 8
Dependent Claim
32 words
The machine of claim 1, further characterized by said holding and twisting means mounted for movement longitudinally of the machine in the direction of movement of said twisted wires and decorative material.
Claim 9
Independent Claim
87 words
A method of making an artificial tree limb comprising the steps of feeding twisted wires with simulated needles therein to a pair of spaced cutters by a reciprocating motion transverse to the machine, feeding wires and decorative material to a pair of pulleys, cutting the twisted wires with simulated needles to lengths determined by the distance between said spaced cutters, twisting said wires and decorative material and catching said lengths of wires with simulated needles therein in a position substantially perpendicular to said wires with decorative material.
Claim 10
Independent Claim
87 words
A method of making an artificial tree limb comprising the steps of feeding twisted wires with simulated needles therein to a pair of spaced cutters by a reciprocating motion transverse to the machine, feeding wires and decorative material to a pair of pulleys, cutting the twisted wires with simulated needles to lengths determined by the distance between said spaced cutters, twisting said wires and decorative material and catching said lengths of wires with simulated needles therein in a position substantially perpendicular to said wires with decorative material.
Claim 11
Dependent Claim
27 words
The method of claim 8, further characterized by bending the ends of the cut lengths of said twisted wires with simulated needles following the step of cutting.
Claim 12
Dependent Claim
25 words
The method of claim 9, further characterized by the steps of cutting and bending performed by the cammed operation of cutting and bending slide elements.
Claim 13
Dependent Claim
35 words
The method of claim 8, further characterized by cutting said twisted wires and decorative material after a predetermined number of lengths of wires with simulated needles have been wound therein to form an artificial limb.
