TEXTILE MACHINE Filed NOV. 10, 1932 hwud'urs: STEPHEN n, FULTON GEORGE A. ARME'T HENRY Ewwc Patented Dec. 3, 1935 UNITED STATES,
PATENT OFFICE TEXTILE MACHINE Application November 10, 1932, Serial No. 641,980 In Great Britain November 18, 1931 3 Claims. (Cl. 24227) The present invention relates to yarn winding machines and in particular to pirn winding machines or similar machines in which the yarn is wound on to a conical or tapered surface. It has for its object improvement of the thread guiding mechanism of such machines, especially for the reduction of friction and tension and for the improvement of the building of the package.
According to the present invention a pim winding or similar machine (hereafter referred to for brevity solely in connection with pirn winding) is equipped with a traversing guide which is curved so as to conform closely to the curvature of the surface of the mm, and is provided with a narrow slot through which the yarn passes to the pirn. Thus while the oncoming yarn is allowed to oscillate freely within the slot as the winding point traverses the length of the chase of the pirn from the broad part to the narrow part and back again, the curvature of the slot causes the yarn to be controlled at a point at a substantially constant distance from the point at which the yarn meets the pirn, irrespective of the portion of the chase on to which the thread is being wound.
By suitable adjustment of the guide, the yarn is guided on to the pirn from a point quite close to the body of the pirn, thus preventing excessive and variable lag of the yarn at the extremities of the traverse which might cause soft places to be formed with consequent insecurity of the grip of the yarn on the pirn. This lag may be still further reduced by making the slotin the guide as narrow as possible. At the same time the slot in the guide enables the yarn to proceed in as direct a line as possible to the pirn with consequent diminution of friction and tension.
:The guide is provided with means for attaching it securely to the traverse rod and is preferably of light but rigid construction. For example it may be made of wire which may be easily bent to the desired shape, the slot being formed by bending the wire to correspond to the curvature of the pim surface and sharply bending back again along itself, leaving a space between, through which the yarn may run.
One end of the wire may be twisted or otherwise arranged to be fitted to the traversing rod. The free end of the wire may be bent to form a guide bar, conducting the yarn to the slotted guide, and thus fulfilling one of the normal functions of the breaker bar frequently employed in winding machines. The guide may also be made as a pressing in which case also the guide bar may be made integrally with the slotted member constituting the guide proper.
The invention will now be described in greater detail with reference to the accompanying drawing butiit is to be understood that this description is given by way of example only and is in no respect limitative.
Figure l is a plan view of yarn traversing mechanism for the purpose of winding yarn on to a pirn.
Figure 2 is an end elevation of the mechanism shown in Figure 1. m
A pirn tube 3 is carried on a spindle 4 extending from the side of a suitable gear box of which part is shown at 5. The spindle 4 and the pirn tube 3 are rapidly rotated from within the box 5 and the yarn 6 (shown clearly in Fig. 2) is there- 15 by wound on the tube. The yarn in passing to the pirn tube 3 passes over a guide bar I and through a slotted guide 8, the guide 8 being formed from a piece of wire which is bent into a curved shape as shown in the figures and as se- 20 cured by means of a screw 9 to a traversing part Hi. It will be seen that the guide 8 is bent into a curve which embraces the pirn tube 3 and then is turned back on to itself, after which it passes upwardly and is bent again to form the bar I lying 25 transversely to the slot formed in the guide and. adapted to lead the yarn 6 to the slot. A small knob H terminates the wire as a protection.
The slotted guide 8 is of such curvature as to intercept a substantially constant small length 3 of yarn passing to the pirn, the drawing clearly showing the equality of the length a of the part of the yarn 6 passing to the outside of the pim to the length b of the yarn when passing to the smaller diameter of the pirn as shown in dotted 35 lines at l2. The bar 1, forming part of the guide conducts the yarn into the slotted guide at such an angle that this constancy of length is maintained. As a result the amount by which the yarn lags behind the guide remains constant, since it 40 depends on the length of yarn between the guide and the pim which is caused to be constant by the nature of the yarn guide according to the invention.
The guide according to the invention is mounted 45 on the traversing part It which in turn is carried on a rod I3 which is oscillated in the direction of its length to traverse the yarn on to the pirn tube 3. The traversing pm "I is attached to the rod l3 by means of two arms l5 between 50 I which lies a disci6 secured to a screw threaded hub II. The disc 16 controls the diameter of the package, since when it comes into contact with the filaments, the wheel I6 is revolved by the rotatory motion of the pirn and in conjunction with the hall thread I l on the rod l3 moves the travers-.
ing part III a little along the rod !3 so that the next traverse is disposed somewhat to the right of the last. The initial building of the yarn package on the pim tube 3 is accomplished by means of a former I8 co-acting with a member i 9 carried by the traversing part III and acting in the usual manner. In order to adjust the traversing memher II! at the beginning of each traverse, the hub il may be pressed towards the spindle 4, and so disengaged from the half thread l4, when the member 10 may be slid along the rod 13.
What we claim and desire to secure by Letters Patent is:-
1. A yarn guide for a machine for winding pirns and the like wherein the tube upon which the yarn is wound is mounted on a rotatable support, said guide comprising a member forming an arc of a circle concave toward thesupport, said member having a slot therein, the construction and arrangement being such that the distance between the points of contact of the yarn with the package and with the guide is substantially constant during the winding of the yarn package.
2. A yarn guide for a machine for winding pirns and the like wherein the tube upon which the yarn is wound is mounted on a rotatable support, said guide comprising a wire bent upon itself to form a member forming an arc of a circle concave toward the support, said member having a slot therein, the construction and arrangement being such that the distance between the points of contact or the yarn with the package and with the guide is substantially constant during the winding of the yarn package.
3. A yarn guide for a machine for winding pirns and the like wherein the tube upon which the yarn is wound is mounted on a rotatable support, said guide comprising a wire bent back on itself to form a member forming an arc of a circle concave towards the support and having a slot therein, said wire being also bent to form a bar lying transverse to the slot and adapted to guide the yarn through the slot, the construction and arrangement being such that the distance between the points of contact of the yarn with the package and with the guide is constant during the winding of the yarn package.
