SPOOLER.
Specification of Letters Patent.
Patented Mar. is, 1919.
Application filed September 17, 1917. Serial No. 191.670.
To all whom it may concern:
Be. it known that I, Anonzo E. vRnoanns, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an linprovement in Spoolers, of which the following description. in connection with the accompanying drawing. is a specification, like charactcrs on the drawing representing like parts.
This invention relates to spoolcrs and especially to spoolers of that type wherein the bobbin from which the yarn is drawn is supported on a spindle and is provided with a weft or filling wind.
The object of the invention is to provide tension mechanism in this type of spooler of such a character as to insure that the tension on the yarn as it passes to the spool shall be uniform regardless of the amount of, or variation in, the tension of the yarn as it comes from the bobbin.
The yarn is preferably drawn from the filling wound bobbin from the end thereof. As the conical layers of yarn unwind from the bobbin there is thus very little tension on the yarn and what there is varies more or less owing to the varying diameter of the yarn mass as each layer is unwound.
The present invention provides means for producing the required uniform tension on the yarn when drawn ofi a filling wound bobbin.
The invention also has for its object to provide a tension'device which will be selfthreading, that is, one in which it is only necessary to lay the yarn from the bobbin in the direction of the traversing guide and thereafter the yarn will be automatically drawn into proper position in the tension device.
These and other objects of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.
In the drawings,
Figure 1 is a transverse sectional view of a sufficient portion of an ordinary type of spooler with a preferred form of the invention embodied therein;
Fig. 2 is a top plan view of the upper portion of the bobbin holder with the tension device of the present invention applied thereto;
Fig. 3 is a side elevation of the bobbin holder, bobbin and tension device;
Fig. 4 is a side elevation of the upper portion of the parts shown in Fig. 3, looking in the opposite direction;
Fig. 5 is a View in cross section taken on the line A- A of Fig. .4;
Fig. 6 is a rear elevation of the upper portion of the parts shown in Fig. 3.
The invention is not concerned with the particular construction of the spooler and it is unnecessary, therefore, to describe in detail an ordinary type of spooler such as herein illustrated. It will be sufficient to note that the frame 1 of the spooler is provided with the usual drum shaft 2 extending longitudinally of the machine from which belts run to the whirls 3 for driving the spool carriers 4 on which are vertically mounted the spools 5. There are usually two rows of these spools arranged on opposite sides of the machine and driven from the drum shaft. In front of and below each row of spools extends a horizontal rod 6 supported on the frame. Bobbin holders 7 are provided for each spool and such a bobbin holder is herein shown at 7 as a casting recessed to embrace the rod 6 and rigidly secured thereto by the set screw 8. The bobbin holder is mounted on the rod 6 at an inclination to the horizontal although its particular position in this respect may be varied as desired. At its lower end it is provided with a step 9 on which is mounted a spindle over which is placed the bobbin 10.
The yarn 11 runs from the bobbin through a traversing guide 12. These traversing guides, one for each spool, are carried by a horizontal traverse rod 13 which by suitable mechanism is given a vertical traversing movement over the length of the spools.
At the front of the frame 1 and beneath the bobbin holders and supported by the brackets 14 are mounted the boxes 15 to receive the full bobbins while between these boxes and the frame are the open mouthed hoppers 16 for the spent bobbins.
All of the foregoing parts are of a familiar and well known construction of spooler and are illustrated and described simply for the purpose of enabling a dis closure of the invention to be made.
The invention presents in its preferred form three main elements, a main tension device, a preliminary tension device and a directing guide. These parts are all mounted between the bobbin support and the travei'sing guidehand preferably are mounted of bars 17 herein shown as four in number are formed of two wire loops the lower ends of which are embedded in or securedto studlike projections 18 formed in a bracket 19 secured to or forming a part of the bobbin holder 7 while the other set of bars 20 also four in number are likewise shown as formed into two wire loops, the lower ends 'of which are inserted in a bar 21 pivoted at its endsin bearings 22'projecting from the bracket 19.
The bar 21 has extending laterally therefrom an arm 23 to the free end of which is suspended a weight support 24 upon which may be placed weights 25 as desired. The arm 23 passes through a slotted plate 26 adjustably secured by the set screw 27 to the bracket 19, and this plate serves to limit the extent to which the arm 23 may be swung downwardly and consequently the extent to which the set of bars 20 may be swung toward the center bars 17.
The two sets of bars 20 and 17 are flared outwardly away from each other at their tops so that the yarn may be placed in position simply by laying it over the top of the device from the bobbin in the direction of the traversing guide. This main tension device is thus self-threading and acts to place any desired degree of tension on the yarn as it runs from the bobbin to the traversing guide, the amount of tension being varied by adjusting the plate 26 and by adding or removing the weights 25 thus varying the sinuosity of the course of the yarn between the bars and the amount of pressure applied by the one set of bars upon the yarn lying against the other set of bars.
The preliminary tension device is mounted between the main tension device and the bobbin support and is hereinv shown as comprising a pair of bars 28 embedded in the bracket 19 and the opposing bar 29 which may also be fixed in position or may if desired be mounted upon a plate 30 adjustable on the bracket 19 by means of the set screw 31. The ends of these bars flare outwardly and the yarn may therefore be laid in be tween the bars by simply passing it over the device.
The third feature is the directing guide which is located between the main tension device and the traversin guide and acts to maintain the yarn in a xed path through the tension device independent of the posimemes tion of the traversing guide.
This-directing guide is shown as a bar or wire 32 the main positioned on the rod 8 that the path of the yarn through the preliminary tension device, main tension device and beneath the directing guide would if prolonged intersect the traversing guide when the traversing guide is midway of its traversing movement.
This arrangement insures a symmetrical winding of the yarn on the spool and prevents the spool from being wound larger at one end than at the other.
It will now be seen that the whole device is self-threading. All that it is necessary for the operator to do is to take the yarn from the bobbin 1O lay it over between the bars of the preliminary tension device along and over and betweenthe bars of the main tension device and over the curved arm 34 and then pass it into the traversing guide. As the traversing guide moves downwardly the yarn will slide down the curved arm 34 and down between the various bars of the preliminary and main tension device and drop into its true course and run out underneath the cross-bar 33 of the directing guide.
It will thus be seen that the device may be simply and readily constructed and is of a character not likely to get out of order. It is readily and automatically threaded. The amount of tension may be varied as re quired under the particular conditions.
It will also be seen that the yarn is drawn oil from the end of the bobbin or along the general axial direction of the bobbin so that the conical layers unwind successively off 110 from the end of the bobbin and very little tension or drag is placed upon the yarn as it comes off the bobbin. What tension there is varies slightly back and :liorthas the diameter of the yarn mass varies throughout the conical layers. The present invention, however, provides means which are entirely independent of the tension or drag upon the bobbin and which insures a uniform tension upon the yarn as'it passes to thespool.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
1. In a spooler, a traversing yarn guide, a bobbin support, a tension device located be tween said guide and said support and acting to place a uniform tension on the yarn as it passes to the spool regardless of the amount of, or variation in, the'tension of the yarn as it comes from the bobbin, and a 130 amount of, or variation in,
directing guide located between the traversing guide and the tension device for maintaining the yarn in a fixed path through the tension device independent of the position of the traversing guide.
2. In a spooler, a traversing yarn guide, a bobbin support, a tension device located between said guide and said support and act ing to place a uniform tension on the yarn as it passes to the spool regardless of the the tension of the yarn as it comes from the bobbin, and a preliminary tension device located between the main tension device and the bobbin support.
3. In a spooler, a bobbin support for a filling wound bobbin, a bracket extending above the end of the bobbin, a preliminary tension device comprising a plurality of alternately arranged bars with their outer ends oppositely flared, a main tension device comprising a plurality of bars divided by alternation into two sets with the outer ends of the said sets flaring away from each other, one set being rigidly mounted on said bracket and the other set being mounted on a support ivoted to said bracket, and means for yieldingly pressing the pivoted set toward the fixed set.
4; In a spooler the combination of elements set forth in claim 3 together with a directing guide comprising a vertical bar, a laterally bent cross-bar and an upwardly curved arm.
5., Ina spooler a traversing yarn guide, a bobbin support, a tension device located between said traversing guide and said bobbin support comprising a plurality of vertically arranged bars divided by alternation into two sets, one set ivotally mounted to swing toward and from the other set, means for yieldingly pressing the pivoted set toward the fixed set, and means for guiding the yarn through said tension device in a path which if prolonged would intersect the traversing guide when the traversing guide is midway of its traversing movement.
In testimony whereof, I have signed my name to this specification.
