Description
Feb. 10, 1931, J..O$WALD THRO STLE FRAME FOR CONTINUOUS SPINNING Filed March 29. 1929 Patented Feb. 10, 1931 UNITED; STATES PATE T Fries JEAN OSWALD, OF IBELFOET, FRANCE, ASSIGNOR TO ETABLISSEMENTS GEORGES KOECHLIN, 0F BELFGRT, FRANCE, A CORPORATION OF FRANCE THROSTLE FRAME FOR CONTINUOUSQSPINNING Application filed March 29, 1929, Serial No.
It is known that throstle frames for continuous spinning comprise several grooved cylinders, generally three, on each of which rests a pressure roller.
Up to the present time the pressure applied to the roller which presses on the second grooved cylinder has been obtained either by the action of the actual weight of the upper cylinder or by the action of an independent distributed weight through the intermediary of a hook and collar between the two first cylinders of the set of three pressure cylinders and thus common to these two cylinders. But success has not yet been attained in applying an independent pressure to the second cylinder of a throstle frame on account of the difliculty of passing a suspension hook between the cylinders for a weight attached specially to the second roller.
- The present invention has for its object an improvement in throstle frames consisting in applying an independent pressure to the second cylinder by book and pressure weight means situated beneath the cylinders.
The suspension hook for this weight which passes between the cylinders, in some cases,
may be controlled in its inclination either by any part of said hook resting on any of the pressure or grooved cylinders, or by an arm which rests on one of the neighbouring pressure rollers.
'The pressure weight for the second cylinder can be applied to one or moresuccessive hooks.
' In the accompanying drawing is described by way of example an embodiment of the invention.
In this drawing Figure 1 is a view in elevation taken from the front I of the second grooved cylinder and of its pressure roller. Figure 2 is a view of a section through 2-2 of Figure 1.
Fig. 3 is a section of a modified embodiment and Fig. 4 a section of another modification.
1, 2 and 3 are the three grooved cylinders,
' and 4, 5 and 6 their pressure rollers.
The pressure is supplied in the lmown man I nor to the first cylinder by a weight acting through a hook 7.
An independent pressure is applied in acssas ee, and in France November 22, was.
cordance with the invention to the second roller by aweight 8 suspended by a pin 9 to the curved. extremity 10 of a hook 10 which passes behind this second cylinder and'which engages with the spindle 5 of the roller 5.
The hook 10 may be guided at anypart of said hook which can bear against any of the pressure or grooved cylinders and in this latter case preferably against the smooth part of said grooved cylinders, asjshown in Fig. 3.
When the hook 10 is guided by the pressure cylinders it is provided with'an extension 10 which rests against one of the pressure rollers, for instance the thirdroller 6, this latter thus serving to guide and control the inclination of this hook, and prevent it from coming into contact-with the grooved cylinder 2. i
In the modification of Fig. 4 the extension 10 of the hook 1O rests against the first pressure roller 4. v e
The pressure weight 8 can be applied to a single book 10, as in Figure 1, or two neigh bouring hooks 1O which span the spindles 5 of two successive pressure rollers 5. 11 and 12 are the upperand lower cleaning rollers.
l Vha't I claim is: r 7
In an inclined draw frame for spinning machines of the type having intermediate and en-o pairs of superposed rollers arranged step formation, means for loading the upaer middle roller comprising a hook suspended from the upper middle roller, a sus-' pended weight carriedby said hook, and an upwardly and rearwardly directed extension rigidly united with the hook and bearing against the upper roller of the uppermost pair of end rollers.
In testimony whereof I have signed this specification.
' JEAN OSWALD.
