Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
265 words
In a machine for the false twist texturing of textile threads in a plurality of side by side thread treating positions comprising two up-standing spaced support frames positioned in facing relation, an operator walkway at the bottom of and extending between said frames to permit access to said thread treating positions, one of said frames supporting thread supply and thread take-up means and the other of said frames supporting thread heaters and false twist spindles for treating the threads, the thread supply means and the first heater of each thread treating position being located in an upper portion of the frames above the level of the head of an operator, each first heater including an elongate, thread passageway having a inlet at its upper end in the upper portion of the frame and a thread outlet at its lower end adjacent the level of an operator's head, means for removing fumes given off by the heated thread in the heater passageway operatively connected to said thread inlet, and means for transporting and guiding the thread at each thread treating position in a path from said thread supply means through said first heater and to said thread take-up means; the improvement therein comprising a first thread delivery means positioned in said thread path adjacent the head level of an operator within reach of the operator's hands, and wherein said means for transporting and guiding the thread includes means in the upper portion of the machine for pneumatically conveying the thread continuously from the outlet of said first delivery means to the inlet of said first heater.
Claim 2
Dependent Claim

In a machine for the false twist texturing of textile threads in a plurality of side by side thread treating positions comprising two up-standing spaced support frames positioned in facing relation, an operator walkway at the bottom of and extending between said frames to permit access to said thread treating positions, one of said frames supporting thread supply and thread take-up means and the other of said frames supporting thread heaters and false twist spindles for treating the threads, the thread supply means and the first heater of each thread treating position being located in an upper portion of the frames above the level of the head of an operator, each first heater including an elongate, thread passageway having a inlet at its upper end in the upper portion of the frame and a thread outlet at its lower end adjacent the level of an operator's head, means for removing fumes given off by the heated thread in the heater passageway operatively connected to said thread inlet, and means for transporting and guiding the thread at each thread treating position in a path from said thread supply means through said first heater and to said thread take-up means; the improvement therein comprising a first thread delivery means positioned in said thread path adjacent the head level of an operator within reach of the operator's hands, and wherein said means for transporting and guiding the thread includes means in the upper portion of the machine for pneumatically conveying the thread continuously from the outlet of said first delivery means to the inlet of said first heater.
Claim 3
Dependent Claim
52 words
A machine as defined in claim 1 wherein said means for pneumatically conveying the thread includes an elongate thread guide tube extending from the outlet of said first thread delivery means to said heater passageway inlet and is operatively connected to said means for removing the fumes given off by the threads.
Claim 4
Dependent Claim
80 words
A machine as defined in claim 2 wherein said fume removal means includes means for introducing a fluid current, and said pneumatic conveying means and said means for removing the fumes includes junction means connected to the inlet of said first heater passageway, said junction means including a generally T-shaped passageway, the base of which is connected to the inlet of the heater passageway and the arms of which are connected to said current introducing means and said guide tube.
Claim 5
Dependent Claim
34 words
A machine as defined in claim 3 wherein said junction member includes ceramic guide means in said T-shaped passageway to facilitate changing direction of the thread in its path of travel through said passageway.
Claim 6
Dependent Claim
39 words
A machine as defined in claim 3 wherein said junction member includes an internal chamber for directing fluid from said current introducing means in the direction of movement of thread in the thread path of travel through said passageway.
Claim 7
Dependent Claim
258 words
In a machine for the false twist texturing of textile threads in a plurality of side by side thread treating positions comprising two up-standing spaced support frames positioned in facing relation, an operator walkway at the bottom of and extending between said frames to permit access to said thread treating positions, one of said frames supporting thread supply and thread take-up means and the other of said frames supporting thread heaters and false twist spindles for treating the threads, the thread supply means and the first heater of each thread treating position being located in an upper portion of the frames above the level of the head of an operator, each first heater including an elongate, thread passageway having a inlet at its upper end in the upper portion of the frame and a thread outlet at its lower end adjacent the level of an operator's head, and means for transporting and guiding the thread at each thread treating position in a path from said thread supply means through said first heater and to said thread take-up means; the improvement therein comprising a first thread delivery means positioned in said thread path adjacent the head level of an operator within reach of the operator's hands, and wherein said means for transporting and guiding the thread includes a thread guide tube extending from adjacent the outlet of said first delivery means to the inlet of said first heater for pneumatically conveying the thread continuously from the outlet of said first delivery means to the inlet of said first heater.
