Patented Feb. 8, 1944 UNITED STATES PATENT OFFICE TYPE OF APPARATUS OR FRAME FOR WIND- ING CROSS WOUND BOBBINS FOR SPIN- NING MILLS AND THE LIKE Argentina Application August 5, 1942, Serial No. 453,746 In Argentina March 31, 1942 1 Claim.
This invention relates to a novel and improved type of apparatus or frame for winding cross wound bobbins for spinning mills and the like, and has for object an improved winding frame of this kind which, owing to its convenient features of construction and operation, offers several important advantages over the Winding frames of similar type heretofore known and used for said purpose.
Heretofore, the use of cross wound bobbins has not been adopted in a more general way, notwithstanding the fact that the bobbins of this kind unwind in more convenient conditionsthan those formed by parallel superposed layers of yarn, because the machines used for winding such bobbins are of limited yield and low' production, a drawback which has not been compensated in any way, in spite of the advantages of a more adequate unwinding of the cross wound bobbins.
At present, the frames used for Winding cross wound bobbins form a type of bobbin in which unwinding starts from inside, in the same manner as in the usual balls of yarn. Although these frames are of convenient operation in connection with heavy yarns, it frequently happens that when unwinding said bobbins, several turns of yarns will detach together, with the consequence that faults will occur in the finished fabric or breakage of the thread will be caused.
0n the other hand, the length and the capacity of bobbins with the yarn unwinding from outside, either of the cross wound or other type, will be restricted by the size of the tube or spool used therein, which must be of a rather limited length in order to prevent the yarn from breaking when unwinding from the spool, as owing to the extension of the same, the yarn must perform several turns around the spool.
The bobbins of this type also offer the disadvantage that for the reason stated, the tension of the thread when starting to unwind and at the end thereof, will lack uniformity and thus cause a certain unevenness in the finished fabric.
In order to avoid the disadvantages set forth, I have devised the improved winding frame which forms the object of this invention and which, in comparison with the known devices of similar type, prove to be of considerable advantage in use.
The invention also views other objects which will be understood when considering the following description of the same.
In order that the invention may be clearly understood and carried into practice, a preferred form of construction of thesame'has-beenshown by way of example in the accompanying drawing wherein- Figure 1 shows a diagrammatic elevation of the improved type of bobbin winding frame, in accordance with this invention.
Figure 2 illustrates, in plan view, a detail of said apparatus, and
Figure 3 is another detail view which shows the manner in which the yarn is wound for obtaining a cross wound bobbin, and the action of the cone for applying pressure to the yarn.
Similar numbers of reference have been used to indicate like or corresponding parts in the several views.
According to the form of construction shown in the drawings, the novel type of bobbin winding frame which I have devised, substantially consists of a cone I, of wood or similar suitable material, adapt-ed to snugly fit on a spindle or spool 2, being retained in its position thereon by means of a tapering stop or shoulder 3, formed integral with said spool.
When observing Figures 1 and 3, it will be seen that the spool 2 is formed at its lower end with an extension 4, of square shape in cross section, adapted to slidably fit within the hole 5, of a corresponding square shape, formed at the centre of a worm wheel 6 which in turn meshes with a worm gear l, affixed to the drive shaft 8, suitably coupled to a power take-off of the winding frame.
The novel type of winding frame includes also a cam disc 9, rotatably mounted on the bed A and formed integral with a gear member Hi to which rotatory motion is imparted by means of similar gear members H and i2; the latter of said gear members is rigidly secured to the drive shaft 8, above referred to.
On the periphery of the cam disc 9 bears an idler roller ta, rotatably and adjustably mounted in one of the ends of a lever l3, secured to an axle I l, mounted in suitable bearings in the stationary frame and connected, in turn, at its opposite end, to another lever l5, for guiding the yarn.
In a slanting position with regard to the axle of the spool 2, a cone It is mounted loosely on a spindle ll, conveniently supported on a fixed frame member 16a horizontally adjustable on the standard C. Said cone has for its object, among others, to apply a suitable degree of pressure to the yarn H3 at its crossing. position and prevent the same from sliding.
The improved type of winding frame also includes a; counterweight I9; suitably suspended from the lower end of a rod 29, slidably guided in the interior of a bracket member 2| which is carried by the horizontal support B on the standard C. To the upper end of said rod 20, a horizontal arm 22 is secured and the end of this arm 22 exerts a suitable degree of pressure against the upper end of a cylindrical extension or spindle 23, formed on the upper end of the spool 2. Said extension 23 is rotatably and slidably mounted in the inside of a bearing member 24, pivotally mounted at 24a on the support B to swing through an angle and assume the position indicated with dotted lines in Figure 1. When using the bobbin winder above described, the free end of the yarn I8 is wound on the cone i, whereupon this latter is caused to rotate by means of the drive shaft 8, gear I and worm wheel 6, which latter acts, as already explained, on the lower extension 4 of the spool At the same time, the drive shaft 8 will cause the rotation of the cam disc 9, through the gears H], II and I2 and as a consequence of the rotation of the cam disc 9, the lever i3-l5 will be rocked on its axis M for the purpose of guiding the yarn l8, and owing to such rocking or reciprocal motion, the yarn is caused to wind crosswise on the cone 1. The crossing of the yarn may be varied at will by controlling the action of said gears in, II and i2.
As the yarn is being wound on the spool, the head or top of the bobbin will rise and the bobbin with its corresponding spindle 2 and members 23, 22 and 29 will be raised by the contact of the said bobbin with the conical idler it, against the action of the counter-weight is.
On the other hand, when the yarn guide 15 reaches its uppermost position, the yarn IE will bear on the upper edge of the cone iii, as shown in detail in Figure 3, and when the descent of said guide member is initiated, the thread will be obliged to introduce itself between the bobbin and said cone I6, so as to become fixed and pushed into its position of crossing or traversing,
support for the same, having been filled, the
bobbin will continue to be wound on the lower extension 4 of the spool, until attaining the desired length.
This operation having been completed, the arm 22 is raised and the cylindrical extension 23 of the spool 2 is first slidably lifted in the bracket 24 until the lower extension 4 of the spool is disengaged from the gear 6. The spool or spindle 2 when thus lifted may then be swung in the bracket 24 about the pivot 24a so as to permit the spindle to move to the dotted line position shown in Figure 1. Under these conditions, the bobbin which contains a hollow space, is removed together with the cone i. This latter member, while assisting in conveniently placing the bobbin in the shuttle, will also assure the complete emptying of the bobbin.
The suitable degree of solidity or compactness of the bobbin thus obtained substantially depends, in the winding frame in accordance with this invention, of the degree of pressure exerted by the cone I6, rather than of the braking of the yarn. For this reason, slack or loose yarns may be wound to an advantage in this novel device, and breakage will be reduced to a minimum amount in winding as well as in unwinding in the loom.
Besides, the bobbin formed by my improved winder frame, when unwinding, will gradually shorten, without ofiering any resistance to the unwindingof the yarn, so that the tension of this latter will be maintained constant. In consequence, the bobbin may be made of any length as will be permitted by the shuttle of the loom. This feature, together with the absence of an inner spool, and the pressure caused by the particular manner of operation of the winding frame when forming the bobbin, contributes to greatly increase the yield of the machine, in comparison with the capacity of any other known type of bobbin winder.
In short, the novel winding frame according to this invention, produces cross wound bobbins with all the advantages as regards size and duration, of the bobbins unwinding from inside, but which unwind from outside, so that the drawbacks of the former will be avoided.
If desired, the improved winding frame above described may be provided with certain additional or auxiliary fittings, such as an automatic stopping device operated by breakage of the thread when a bobbin of the required length has been wound; means for adjusting the pressure cone, for obtaining bobbins of different diameters and other suitable or convenient means, not described in this specification, as their construction is based on well known principles and, though contributing to increase the yield of the winding frame, they are not absolutely necessary for producing cross wound bobbins of the type above set forth.
In the arrangement described it will be apparent that the gearing 6, l, 8, It, ll, 52, and cam 9 are mounted in a bed portion A of the machine and that the bracket 2| is carried by the horizontal support B of vertically extending standard C mounted on the bed, the said standard also constituting a support for the bracket which carries the spindle I? of the cone I6. This structural arrangement provides compactness and contributes materially to the functioning of the apparatus.
From the foregoing description, the nature of this invention will have fully been understood and no further explanations will be required by those skilled in the art.
It will be evident that several modifications of construction and detail might be introduced without departing from the scope of this invention, as clearly set forth in the appended claim.
