10 Claims.

This invention relates to creels and the like, such as are used in the textile industry to support multiples of yarn supply cones which are to be unwound incident to warping or other yarn transfer operations common in the textile art; and to the individual yarn cone units of such creels.

In the art of warping, particularly as carried out by the modern shops of limited capacity, it has been the practice to employ relatively small standard spool creels of approximately four hundred and fifty spool capacity, for applying the individual yarns from these creels unto a measuring or warping reel, and from the latter directly unto a warp beam. After such shops have their equipment installed for most efficient operation, and production orders develop an unusual output demand, certain problems arise in connection with such creel arrangements. For example, to satisfy an unusual output demand, it may become necessary to increase the creel capacity. However, in the referred to shops, space limitations usually make it difiicult, if not impractical, to substitute creels of larger dimensions than those already in place. Then again, a more or less general industrial increase in the demand for loaded creel spools may create supply and delivery diflicultie preventing the said shops from promptly obtaining an adequate supply of spools for operating their creels as desired, or necessary, to avoid production losses, or the loss of orders which cannot be promptly satisfied.

One object of my invention is to overcome the mentioned and other difiiculties, by providing novel creel equipment adapted to effect increased yarn capacity over the said standard creels without necessitating an increase in the installation space.

Another object is to provide such equipment which is more efficient in operation than the referred to standard prior art creels.

A further object is to provide such equipment having novel features of advantage over the said heretofore available creel constructions.

Another object is to provide such equipment from which the yarn can be withdrawn at a relatively higher speed, and which does not necessitate as frequent replenishment of the individual yarn sources, as the mentioned standard spool creels.

An additional object is to provide such equipment in which the yarn tension of all the yarns is alike at all times and remains uniform during the entire yarn unwinding operation.

It is also an object of my invention to provide a novel yarn supply unit for creels and the like, which is simple in construction; adapted to take standard size yarn cones of all materials ordinarily used in warping; designed to limit or confine the ballooning of the yarn withdrawn from such a cone; which embodies yarn guide and tension means in a new and advantageous manner; and has other desirable features not present in available creel units of this general type.

With these and other objects in view, which will become more apparent from the following detailed description of certain practical and illustrative embodiments of my novel creel and yarn cone unit, shown in the accompanying drawings, the invention comprises the novel elements, fea tures of construction and arrangement of parts in cooperative relationship, as hereinafter more specifically pointed out in the claims.

Referring to the drawings:

Figure 1 is a side elevational view of a creel embodying my invention.

Fig, 2 is a partial front elevational view of the upper end of the creel shown in Fig. 1, as seen by looking in the direction of the arrow A in said figure.

Fig. 3 is an enlarged fragmentary side elevational view of a certain creel frame element shown in Fig. 1, and two identical yarn cone units which form part of my invention.

Fig. 4 is a top plan view of Fig. 3, as seen by looking in the direction of the arrows 4-4 in said figure.

Fig. 5 is a view similar to Fig. 4, but showing a certain member of the yarn cone unit in another position.

Fig. 6 is an enlarged cross-sectional view of the yarn cone unit of my invention, taken substantially as indicated by the arrows 6-6 on Fig. 4.

Figs. '7, 8 and 9 are, respectively, rear elevation, cross-sectional and front elevational views of the upper yarn cone unit shown in Fig. 3; Figs. 7 and 8 showing the unit as seen by looking in the direction of the arrows 1-1 and 8-8 in Fig. 6.

As shown in Figs. 1 and 2, one practical creel construction of my invention comprises two vertical end frames H and I2, which are united by a plurality of horizontal members or boards l4, rigidly secured to the end frames in suitable manner. The end frames l l and I2 are provided with a suitable wheel arrangement at their bottom, as indicated at l5, to facilitate movement of the creel along the floor.

The end frames H and l 2 may be of triangular configuration as shown, or otherwise constructed I to provide, with the cross-members M, a yarn supply mounting surface of desired areaand inyar'n's as later described.

Side plates or brackets II are rigi y secured to the top board l4, across the outer upper ends of which is fixed a cross-bar I] having a circular glass rod l3 secured to its top in such manner 'as to present a smooth supporting and aligning surface over which the yarns from the creel supply units may pass on their way to the usual measuring or warping reel (not shown) Inprder to maintain the yarns in desired spaced relationship when passing over the rod l3, a common type of reed I3- is provided rearwardly of the rodl8, so that the individual yarns may be separated from each other by the spacing or separating elements IS 01' the reed, in accordance with well top and bottom of the casing 23. The pivot pin 23* is fixed in the casing 23, while the pin 23 is loosely engaged in an aperture of thecasing 23 and provided with a head at its top and bottom. This arrangement permits the intermediate part of the bracket 25, which carries the yarn guide means 26, 21, and the yarn tension means 23, to be moved-or swung in a horizontal plane from the position shown in Fig. 4, to the position known practice. The reed I8 is mounted on the cross-bar H, or otherwise secured to the frame structure of the creel, to accomplish the stated purpose. I

A second cross-bar l9, similar to the cross-bar i1, is mounted on the top frame member 4, at the rear and slightly below the bar i1, and this second cross-bar l9 also has a circular glass rod i9 secured to its top to provide a resting surface for the yarns Y when in relaxedor lowered position, as indicated by the dot-and-dash line Y at the top of Fig. 1.

The individual yarn cone units of my invention, generally indicated by the numeral 20, are secured in suitable manner to laterally inclined and uniformly spaced bars or slats 2|, of wood or other material, fastened, against the horizontal members I4.

As shown in Fig. 2, the units 20 are arranged in laterally staggered vertical rows to achieve minimum spacing therebetween, and to effect separation of the yarns extending from the individual units to the glass rod i8 in substantial correspondence with the spacing determined by the reed l8. It will also be noted from Figs. 1

- and 2, that the units 20 are arranged in vertically and laterally inclined superimposed relationship in each vertically extending row, that is, each row of units is inclined rearwardly from the vertical, as shown in Fig, l, and inclined sidewise from the vertical, as shown in Fig. 2.

As illustrated in Figs. 3 to 9 inclusive, one practical form of my -novel yarn cone unit 20 comprises a plat or support 22, a, cylindrical casing 23, a yarn cone mounting or pin 24, an arcuate bracket having an extension 25', yarn guide means 26 and 21, and yarn tension means 28 The cylindrical casing 23 and the yarn cone mounting pin 24 are fixedly secured to the support 22 in such relation that the pin 24 is centrally located within the casing. The diameter of the casing is such that all standard yarn cones of various types of materials can be accommodated therein in such mannerthat the inner surface of the casing is spaced from the cone a determined distance to effect desired confinement of the ballooning of the yarn when being unwound from the cone.

The plate .22 is secured to the frame element 2| by wood screws 22 which pass through apertures 22 in said plate, as shown in Figs. 6 and 7.

The end portions 25 and 25 of the bracket 25 are connected withpivot pins 29 and- 29 located at diametrically opposite points at the shown in Fig. 5.

When the bracket 25 is in the position illustrated in Fig. 4, the yarn guide means 26, 21, and the yarn tension'means 29 are in active or operative position, and the bracket 25 extends vertically and centrally across the front of the easing 23. This places said yarn guide and tension means in substantial alignment with the longitudinal axis of the yarn cone mounting pin 24, as clearly illustrated in Fig. 6.

To seat a full yarn cone C onthe pin 24, the bracket 25 is first swung sidewise to a position adjacent the front of the casing 23, as illustrated in Fig. 5. This leaves the front end of the casing 23 open, or unobstructed, for ready inthrough central apertures in the discs. The lower end of the pin 32 is threaded and passes through a correspondingly threaded aperture centrally located in the bracket extension 25*. To maintain the pin 32 fixed in the position shown, a lock nut 33 is applied to its lower threaded end against the underside of the bracket extension 25. To prevent vibration of the tension discs, a felt pad 34, or other vibration absorbing means may be interposed between the lower disc 3| and the upper surface of the bracket extension 25, as clearly illustrated in Fig. 6.

,During unwinding of the cone C, the yarn Y passes from the cone through yarn guide 26, between the tenslon discs 30 and 3|, through yarn guide 21, over the glass rod l8 through reed I8 and to the measuring reel (not shown).

During such unwinding operation, ballooning of the yarn Y is limited or confined by the inner wall of casing 23, as illustrated in Fig. 6.

In order to prevent accidental movement or displacement of the bracket 25 while in the active or operative position shown in Figs. 4 and 6, the bracket is releasably held in place by detent means comprising a convex protuberance 35 on the upper bracket part 25', which registers with a complementary concave depression 36 in the casing 23. A compression spring 31, on the pivot pin 29, between its head and the bracket part the pivot pin 29, so that the application of sufficient sidewise force on the bracket 25 overcoming the downward pressure of the spring 31, will effect release of the detent means and permit free movement of the bracket 25 to its inactive position as portrayed by Fig. 5.

When the bracket 25 is moved from active to inactive position, or vice .versa, the yarn guide and tension means carried thereby are moved in a horizontal or substantially equi-distant plane relative to the glass rod l8.

Although I have found in practice that such parts of the unit 20 as the support plate 22, pin 24, casing 23, bracket 25, pivot pins 29 and 29 andtension device 28, can be made of metal in satisfactorily provide the structural and functional advantages of my invention, it is to be understood that such parts may also be formed of plastic or other materials to impart tothe unit whatever advantages may accrue from such substitution of materials. Of course. the yarn guide means 26 and 21, may be in the form of porcelain eyelets.

The creel construction of my invention illustrated by Figs. 1 and 2, when made substantially the same in size and general configuration as the previously referred to standard form of spool creel (capacity 450 spools) used in warping shops of moderate capacity at the present time, has a yarn cone capacity of abouttwo hundred and twenty-five cones. Since standard size yarn cones contain much more yarn than standard size yarn spools, the actual yarn capacity in weight of such a standard spool creel compared with one constructed in accordance with my invention is approximately 150 pounds as against 675 pounds, or roughly, my improved creel has about five times the yarn weight capacity of such a standard spool creel. Furthermore, it is a well known fact that the yarn unwinding speed of such a standard spool creel is limited by the practical speed of rotation of the spools. My improved creel is not subject to this limitation and it is therefore, entirely practical to attain an unwinding speed with the'latter which is three or more times greater than that of such standard creels. A further comparative advantage resides in the perfectly uniform unwinding tension of the yarns from all the cone units of my improved creel construction, as compared with the varying tension of the yarns from the spools of a standard creel, which results from their varying diameter and change in rotational force required as the weight of the spools decreases. These and other comparative advantages make it possible to reduce the cost of the yarn transfer operation to approximately one-half when my improved creel is employed in place of the said standard creels.

Since the yarn cone units individually embody yarn guide and tension means in combination with means for confining or limiting the ballooning of the yarn and means for accommodating standard size cones of various matrials used in warping, such units are also adapted to function as complete attachments for converting the referred to standard spool creels into cone creels. This can be accomplished by removing the usual spool, yarn guide and tension means from the frames of said standard creels, mounting thereon my novel units 20, and adding a glass rod and reed or equivalent arrangement at the top, substantially as shown in Figs. 1 and 2. Besides attaining the mentioned advantages of my improved creel construction, such a change will obviously eliminate all difiiculties and disadvantages characteristic of the spool creel and impart the benefits and advantages of my invention without change in the size or general configuration of the creel equipment previously utilized. The units 20 can be similarly utilized as attachments for improving other forms of yarn feeding equipment.

Of course, the creel and yarn cone unit improvements specifically described, by which I obtain the noted results, can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.
