RING SPINNING FRAME FOR WOOLENS Filed Nov. 19. 1928 I Patented Sept. 17, 1929 UNITED STATES PATENT OFFICE PERCY JOWET'I AND MALCOLM CHARLES MARSH, LEEDS, ENGLAND, ASSIGNORS TO THE BRITISH RESEARCH ASSOCIATION THE \VOOLEN AND WOBSTED INDUS- TRIES, 0F TORRIDON, LEEDS, ENGLAND RING-SPINNZNG FRAME FOR WOOLENS Application filed November 19, 1.928, Serial No. 320,459, and in Great Britain February 27, 1928.
This invention relates to ring spinning frames for W001 and also cotton and other fibres, the chief object being to control the thread during drafting with a view to the production of a more uniform yarn at a higher draft than usual.
According to the invention, means are pro vided in place of the usual deflection rod whereby the tension of the thread controls its mode of entrance to a false twist tube which leads the thread into the nip of the drawing rollers. The mouth of the false twist tube may be countersunk or flared and have a plurality of notches or projections in or on its conical or flared face, while the thread may first pass over a tension controller which may consist of a revolving roller or some such equivalent device, to gether with a smooth floating roller, the downward pressure upon which is counterbalanced in any appropriate manner.
In order that the invention may be clearly understood and readily carried into effect, the same will now be more fully described with reference to and by the aid of the accompanying drawings; wherein Figure 1 is a side elevation of a false twist tube and means whereby the tension of the thread controls its mode of entrance thereto,
Figure 2 is a plan View of the false twist tube drawn to an enlarged scale.
Referring to the drawings, the thread 1 first passes over a tension controller which, in the embodiment shown, consits of a revolving roller 2 together with a smooth. floating roller 3 the downward pressure upon which is counterbalanced. Thus the floating roller 3, which maybe made of metal or other appropriate material, is mounted at one end of a double-ended lever 4c freely pivoted. at 5, the other end of said lever 4 having slidably mounted thereon a bal ance weight 6. By adjusting the position of the balance weight 6 along the arm of the double-ended lever 1 the tension of the thread 1 is adjusted, and in this way the angle or mode of entrance of thread 1 into the mouth piece 7 of the false twisting tube 8 is controlled. As shown, the thread 1 is just clear of the roller 2 when working normally, saidroller *2 serving to prevent the angle ofentrance of the thread 1 into the mouth piece 7 from becoming too acute. The mouth piece 7 of the false twist tube 8 is in the form of a countersunk or flared means may be provided on the lower end of the twist tube 8 so as to grip the thread 1 in its passage into the nip of the drawing rollers 11, and in this connection the spring jaws 10 are so shaped that they may be brought as close to the nip of said rollers 11 as possible; The false twisttube 8 is revoluoly mounted in abearing bracket 12 secured to a cross member 13 of the machine frame, and said tWlSt ttlbQ 8 is adapted to be driven by means of a pulley 14 secured thereto by a setscrew 15, although it will be understood that any other appropriate means may be employed fordriving the false twist tube 8; The mouthpiece 7 is secured in position within the upper end of the false twist tube 8 by means of a set screw 16,
while a set screw 17 serves to secure the bal-J ance weight 6 in any adjusted position on the armof the double-ended lever 4.
What we claim as our invention is 1. In combination with aspinning machine of the class described, a twist tube having at one end a flared mouth provided with oppositely disposed inclined radial. projections arranged to engage the thread and impart a twist thereto upon actuation of the tube, depending resilientfingers connected to the opposite end of the twist tube for applying a uniform pressure on the thread as it issues from the tube, a lever associated with said twist tube, said lever having a smooth floating roller for engaging the thread, and a revolving roller positioned in front of said floating roller for controlling the angle at which the thread enters into the twist tube.
2. In combination with a spinning machine of the class described, a twist tube having-at one end a flared mouth provided with oppositely disposed inclined radial projections arranged to engage the thread and impart a twist thereto upon actuation of the tube, depending resilient fingers connected to the opposite end of the twist tube for applying a uniform pressure on the thread as it issues from the tube, a lever associated with said twist tube, said lever having a smooth floating roller for engaging the thread, adjustable means for counterbalancing the downward pressure of said roller, and a revolving roller positioned in front of said floating roller for controlling the angular entrance of the thread into the twist tube, said revolving roller arranged to' be normally out of engagement with the thread. i
3. In combination with a spinning machine of the class described, a twist tube having at one end a flared mouth provided with oppositely disposed inclined radial projections arranged to engage a thread and impart a twist thereto upon actuation of the tube, the-opposite end of thetwist tube havinga reduced axial extended portion, drawing rollers below said reduced portion, depending spring fingers connected to said tubeand extending close to said drawing rollers soas to exert a uniform pressure on the thread as it passes to the nip of the drawing rollers, a lever associated with said twist tube, said lever having a smooth tloatrevolving roller posltioned in front of said floating roller for controlling the angular entrance of the thread as it enters the twist tube.
4. A twist tube for spinning machines having at one end a mouth provided wit-h inwardly inclined pro1ect1ons for engaging the thread, and. spring fingers connected to the opposite end of the twist tube for applying a uniform pressure on the thread as it issues from the tube.
5. A twist tube for spinning machines having at one end a mouth provided with inwardly inclined projections for engaging the thread, and a reduced axial extending portion at its opposite end, and resilient means, extending axially from the reduced. portion of the twist tube for applying a uniform pressure on the thread as it issues from the tube.
