The subject of the present application for a patent is a continuous supply creel for winding warp beams in variable combinations, illustrated, byway of example, in the accompanying drawings, in which 2-- Figure 1 is a perspective view of a compartmental column comprised in the invention.

Figures 2 and 3 show, respectively, a perspective view and a side view of a carrier holding tray.

Figure 4 is'a perspective view of a carrler.

Figure 5' is a detail View of a thread distributor.

Figures 6' and 7 are sections on the lmes VIVI and VII-VII of Figure 5 respectively.

Figure 8 is a sect-ion on the hue VIII- VIII of Figure 14 showing two carriers placed side by side.

Figures 9 and 10 show respectively a front view and a vertical section of a detector device.

Figures 11 and 12 are diagrams illustrating the distribution of threads drawn out of a series of columns. 7

Figure 13 shows diagrammatically a set of columns with the collecting and tensioning rollers.

Figure 14: is an isometric view of the columns, distributors and detector.

The creel forming the subject of this invention dispenses with successive stages preliminary to the winding of the warp beam. The said continuous supply creel is composed substantially of columns of thread carriers combined to form sets supplying groups of warp ends of varying quantities. The latter are preferably kept apart by pins or lease rods which determine the spacing of each group, the various groups being afterwards brought together on suitably arranged horizontal rollers which impart a'uniform tension to the completed warp.

Before being wound on the warp beam, the threads pass between pins or lease rods, which determine the spacing between the groups, so that they can be arranged laterally in position corresponding with the draft 59 of the warp and enable the component threads to be arranged in a varying manner, which cannot be obtained by the existing method of working, in which the draft is fixed beforehand.

As shown in the drawing, the column 1 is divided into several compartments, each of which contains several metal trays 2, with central partitions 3, and each holding two carriers 4 which in turn contain three bobbins 5. These carriers, which are of sheet metal, the sides being folded over at the bottom and one end being open, hold the bobbins 5, the

axes of which converge towardsthe unwinding point, which is situated in the plane of the partition 3. There is always one carrier operative, the other being in reserve and brought into operation when the bobbin in the first one has run out. At one end of the partition 3 there is a support 6 on which rests the connecting thread running from the head of one bobbin to the base of the other and enabling the thread, when the first carrier has become empty, to pass over the partition 3 andbring the second reserve carrier into operation. 5 l

The thread issuing'from the carrier passes to a detector composed of a vertical bracket 7 positionedon the columnl adjacent the inner ends of the trays 2 intothe interiorof which extends a metal spiral 8 connected to? a movable oscillating weight 9 carrying a finger 10 adapted to engage a. hook 11 pivoting on the said spiral 8. To one side of the spiral 8 and-on the bracket 7' is secured asp-iral hook 12, whilst on the opposite side is arranged a contact strip 13 attached to a conducting wire 14. A conducting wire 15 is connected to; the spiral 8. Ordinarily, the thread passes through the spiral 8, lifts the hook 11 and passes through the hook 12, so that the ho-okll, being drawn away from the strip 13 ordinarily breaks the electric circuit (for example comprising a lamp, not shoWn,-) and remains out of contact with the finger 10, which is out of actionso long as the thread is unwinding from the greater diameter of the bobbin. hen the thread-is unwinding from'the lesser diameter of' the bobbin, and is thus subjected to greater tension, the hook 11 is d rawn'further outwards O0 by the traction of the thread, and the weight 9 attached to the finger 10 is brought into action by said finger. When the thread is again unwinding from the greater diameter 'of the bobbin, the weight 9 restores the hook 11 to its original position, and consequently the thread is kept in constant tension.

In the event of the thread breaking or being overstrained, the hook 11 rises to the level of the hook 12 and releases the thread, With the result that the weight 9 brings it into contact with the strip 13, thus completing the electric circuit, the ruptureor overstraining of the thread being then revealed by the lighting of the detector lamp.

The thread issuing from the hook 12 of the detector device passes to a distributor 40 (Figure 5) composed of the vertical bars 14, 15, 16 and the horizontal bars 17, 18, 19,

20 pivotally connected to the vertical bars, so that the bars can be brought closer together or moved apart whilst still remaining parallel. The threads from the first compartment of a column are carried over the pins or hooks 21 of the horizontal bar 17 and, passing under the bar 18, are carried round the hooks 22 of the bar 19, and finally, after passing to the bar 20,remain separated, and

pass on to a roller 23. The threads from the second compartment engage the pins 24 of the bar 18 and then, passing between the pins or hooks 22, ofthe bar 19 pass between the pins or hooks 25 on the arm 20, and like the former are led to the roller 23, whilst the threads from the third and fourth compartments are arranged above those from the 1st and 2ncb compartmentsand follow the lines indicated in Figure 5 to the correspondin roller 23. 7

y altering the inclination of the arms 17-20 constituting the distributor, the threads carried by said arms can be brought closer together, so as to vary the number of Warpends per unit of count. Assuming, for purposes of demonstration only, the 'nu1n ber of threads in acompartment to be 10, then, if the arms of the distributor are arthe feeding of the carriers, which is effected from outside the line, thus presenting an advantage in the organization of the work. Thus an infinite series of warp drafts can be obtained and with a metric length which cannot be obtained at present, because the draft has to be settled in each case, unless the draft is in series, because the winding of the warp as a whole on a single beam does not allow lateral shifting of the threads which, being laid side by side from the beginning, cannot be separated.

It will be understood that the details of shape, construction, structure, dimensions, application, finish, assembling arrangement, or the like, may be varied according to circumstances withoutdeparting from the scope of the invention, set forth in the claims hereunto annexed, as may be found more suitable and better adapted to conditions of practice. I claim r i 1. A creel comprising a plurality of compartmental columns, removable trays in the columns, a plurality of thread bobbins in eachtray, a distributor for each column adapted to space the threads from the bobbins and consisting of verticalbars, horizontal bars pivoted to the vertical bars so that they may be moved in parallel relationship, and thread guiding pins on the horizontal bars.

2. A creel comprising a'plurality of pairs ofcompartmental columns, the columns in each pair facing each other, thread carriers in the compartments of each column, a distributor for each column adapted to space the threads issuing therefrom and means for adjusting the spacing of the threads, said means comprising thread bars pivotally connected to a plurality of vertically disposedbars, one of which is rigidly afiixed to said compartmental columns.

ranged horizontally and are 40 centimetres in e length, there will be a thread every 4 cm.,

Whereas, retaining the 1O threads and inclining the arms at an angle of 45, there will be a thread at every 2 cm., that is to say, two threads per 4 cm. It follows, therefore, that the spacing is variable in relation to the 7 length of the arms and the number of threads, 7

and depends on the greater'or smaller angle of inclination of the arms of the distributor.

By combining the columns of carriers into sets and arranging these in parallel lines at suitable intervals, an indefinite aggregation ofthreads can be obtained, whichcan be subdivided by the removal or substitution of columns and groups so as to maintain a constant relation between the numberof groups removed and substituted and the total num-
