MEANS FOR PREVENTING DOUBLES IN RING SPINNING, DOUBLING, AND vLIKE FRAMES Filed Feb; 15, 1928 Patented May 21, 1929.
UNITED STATES PATENT OFFICE.
WILFRED WHITE-HEY, OF ELLAND, ENGLAND.
' MEANS FOR PREVENTING DOUBLES IN RING SPINNING, DOUBLING, AND LIKE FRAMES.
Application filed 'February 15, 1928, Serial No. 254,475, and in Great Britain June 25, 1927.
In ring spinning and doubling, twining, and the like, it is found that doubles or four-folds frequently occur, causing considerable loss in waste and deterioration in the quality of yarn being spun. This is caused in nearly all cases by excessive ballooning of the thread between the guide wire and the twisting medium and following a rupture of one of the threads caused thereby.
When excessive ballooning takes place,
two adjacent threads come into violent contact with each other which generally results in a rupture of one of them, whilst at the same'time it becomes entangled with the other thread and henceforth continues to be twisted along with the same until stopped by the operative. In the case of an ordinary breakage of a thread, this nearly always takes place below the guide wire,'and as the drawing-0d rollers continue to deliver, the loose end is very often caught by the adjacent end, with the same results as above described. Several different devices have previously been used for preventing or avoiding the formation of four-fold or doubles by a broken end or thread lashing into an adjacent one, one of which consists of a metal strip or plate whose side edges are provided with slits therein whose opposing sides are parallel for catching and breaking any ends that may have left the thread guide and lash against them. In another device, a triangular slot is formed in the said plate and a further slot affording communication therewith for threading of the loose end; slits with opposing parallel sides are also formed therein right and left of the thread for the purpose aforesaid. In another device composed of bent wire the sinuosity of the passages provided therein for the thread is relied upon to break the same.
The object of the present invention is an improved construction of said thread guides composed of wire bent in such a manner so as to form upon the right hand and upon the left hand of the thread, a fine or slightly tapering slot or recess the sides of which gradually converge and eventually meet at or near the bend forming the apex or termination of each recess, whereby the thread whether of thick or of the very finest counts, upon being lashed into one of these recesses 1s adapted to wedge itself therein for the purposes aforesaid. Further, the loose ends of the sald guide are adapted to overlap with a passage between them, and are so bent out wardly that a slight pressure thereon is adapted to slightly expand the corresponding recess and release the thread which may be held therein. Provision is also made where strong yarn is being spun, whereby the multiple guide lappet is prevented from be ing unduly raised by an entanglement of the threads thereof.
In place of the usual wire guide provided with a ring or circular eyelet, which in the case of ring doubling frames is generally placed lnimediately below a glass rod, a guide is employed constructed of wire bent in such a manner as to form a space for the thread, the space being provided with a recess at each side tapering slightly until the bent portions of the wire forming the said recesses, meet, as before described. A longitudinal loop extending from the aforesaid space, runs at right angles to the said recesses for the purpose of enabling the guide to be secured to the lappet by bolts or other suitable or well known means, the loose ends of the wire forming the guide being crossed opposite this loop, in such a manner, that a space is pro vided between the said ends for the threading of a loose end in front, at the commencement of operations or following the piecing up of a broken thread.
When the threads are working properly, they are delivered by the drawing-off rollers and pass over the customary glass rod or rods and through the guide forward to the bobbin upon the spindle. In the eventuality of one end or thread becoming attached to the adjacent end upon the left hand thereof, for example, the pull of this thread upon the broken thread causes the latter to be pulled into the left hand tapering recess in the corresponding uide, wherein the stronger it pulls and the tighter the thread becomes wedged therein or gripped thereby, until a rupture of the thread takes place; when the thread has been broken the aforesaid rollers form a lap and pull the loose end upwards out of the nip of the guide or otherwise break it off. Should there be a short length held by the recess it can be removed or cleared upon slightly opening the said recess by applying a slight pressure outwardly to the corresponding loose end of the guide. By forming a bulbous bend outside the meeting faces of the wire the re lease of the broken thread as aforesaid is greatly facilitated.
In the case of multiple guide lappets it is possible, where strong yarn is in process of being doubled, for the tension put upon the entangled threads, to aise the lappet and the whole of the guides thereon in a manner likely to also damage or break the remainder of the threads of the lappet; but provision is made whereby said la ppet is prevented from being raised beyond a predetermined amount, by means of a stop. Where singlelappet and glass rod is used for each spindle such a provision becomes unnecessary.
I attain my objects by the means illus trated in the accompanying drawing, in which Fig. 1 is a sectional end view showing the invention applied to a ring spinning and. doubling frame.
Fig. 2 is a front View of the invention as applied to Fig. 1, showing the attachment of a broken thread to an adjacent unbroken thread and its seizure by the guide.
Fig. 3 is a plan view showing the invention applied to ring spinning and doubling frames embodying multiple guide lappets.
Fig. at is a plan view, and Fig. 5 a side elevation of the improved guide.
Figs. 6 and 7 are plan views of modifications of Fig. 4.
Similar letters refer to similar parts throughout the several views.
Referring to the drawings :-A, B, are drawing-oft rollers, O a standard supporting same, D the roller beam supporting standard C, E are lappets hinging at F upon brackets Gr bolted to the roller beam D. H are glass rods supported at each end by brackets J, all of which are more or less common to existing ring spinning and doubling frames or machines.
K are improved guides preferably burnished, enamelled or plated, adapted to guide the yarn or thread L after passing over the rod H, forward to the spindle or bobbin M upon which it is wound. The said guide is formed from a suitable length of preferably round metallic wire subsequently bent so as to form a longitudinal loop N by which the guide is secured by screws, bolts or other suitable or well known means I? to the lappet E. The sides of the loop are again bent approximately at right angles thereto and back again towards the loop in such a manner that a wedge shaped or tapering recess R is formed therein right and left of the said guide, the loose ends S being adapted to overlap each other and are curved outwardly with a space T between to permit of the threading or passage of the loose end of the thread into the space U communicating with the recesses R upon each side and situate immediately over each spindle or bobbin M. Z is the bulbous bend (see Fig. 6) for facilitatingthe release of the broken thread or for cleaning out the slot R. 01, (see Fig. 7) in place of the loop N this portion of the guide may consist of a single straight portion of wire V with a screw-thread W formed thereon adapted to engage a suitable bracket (not shown) bored and tapped to receive the same. The loose end is bent to form the wedge shaped recesses R and terminates in a curved portion adapted to overlap the base of the part V for the purpose before described. To provide the desired space, U a curved recess is formed in the wire at this part.
The curved ends of the guide and the curved portions at the commencement of the loop N are adapted immediately upon being engaged by a broken thread to guide the same into one or the other of the taperin recesses R for the purposes before describe \Vhere strong yarn is in process of bein spun, to prevent the lappet with a multiple 0? guides from being unduly raised upon its hinges by the tension put upon the thread by the rollers A, B, or from an other cause, a wing bolt X is employed a apted to screw into the bracket G supporting said lappet, the bolt has projections Y thereon which are adapted to engage the lappets on each side and prevent the same from being raised beyond the desired limit. Or any other suitable form of step may be employed, as desired.
What I claim as my invention, and desire to secure by Letters Patent is 1. In a ring spinning and doubling machine or the like the combination with a series of spindles, of wire thread guides situate immediately above the spindles, and each provided with slots or recesses arranged at opposite sides of the thread, such slots being of such size as to be capable of catching and holding the thread and the sides of each slot gradually converging and eventually meeting at or near the bend in the wire forming the apex of each recess, substantially as and for the purposes described.
2. Ring spinning and doubling machines or the like according to claim 1, characterized in that the loose ends of the Wire thread guide forming one side of each tapering recess therein, overlap each other with a passage between them, said overlapping portions being bent outwardly, substantially as and for the purposes described.
3. A thread guide for the purpose described formed of wire bent to provide a supporting shank, an eye for passage of a thread, and arms extending laterally in opposite directions from the shank and each provided with a slot communicating with the eye and of such size as to be ca able of catching and holding a broken thread 4. A thread guide for the purpose described comprising a body provided with an 5 eye for the passage of a thread and two slots extending laterall in opposite directions from and commumcating with said eye,
each of said slots being gradually reduced in width from the eye toward its end remote from the eye and adapted to catch and hold a 10 broken thread from the eye.
In testimony whereof I aflix my signature.
WILFRED WHITELEY.
