To facilitate the changing of bobbins in a creel frame the skewers are sometimes fixed to rotatable carriers, and sometimes carried by travelling holders which can be run out of the frame for making the change. For saving space it has also been proposed to fix groups of skewers to sickle shaped arms which overlap each other in parts. This arrangement does not enable several groups of bobbins to be changed in one operation, and

m is also not suitable for having the skewers in a horizontal or nearly horizontal position.

According to my invention the bobbins are carried by movable holders, or cages, each supporting a number of groups of bobbins, and the axes ll of the skewers of each holder are in different planes. A thread guide bar with eyes for the payed ofi yarn is placed preferably at the intersection of the planes, each holder forming a ldnd of prismatic cage. These holders can be moved 20 without any interference with the paying on of the yarn, even if the outside skewers of the holders make with each other an angle of more than 90. I have found an angle of about 120 to be very convenient in respect of saving space.

25 Several forms of construction are shown by way of example in the accompanying drawings, wherein,

Fig. 1 is a vertical section through one form of creel embodying the invention;

30 Fig. 2 is a plan view, with parts broken away,

of the creel shown in Fig. 1;

Fig. 3 is a vertical section similar to Fig. 1 of another form of the invention, the figure being simplified by showing only a few of the skewers; Fig. 4 is a plan view, with parts broken away, of the embodiment shown in Fig. 3;

Fig. 5 is a vertical section similar to Fig. 3 of another form of the invention;

Fig. 6 is a plan view of the form of the inven- 40 tion shown in Fig. 5, with parts broken away;

Fig. 7 is a vertical section of another form of the invention, taken at right angles to the views 1, 3 and 5; and

Fig. 8 is a plan view, partly broken away, of the 45 form of the invention shown in Fig. 7.

The frame 1 supports a number of cages 2. These are of prismatic shape, either right prisms, as in Figs. 1 to 6, or oblique prisms, as in Figs. 7 and 8. In the examples shown one side of each 50 cage, which is to receive the bobbins, is arcuate, about one third of a cylinder, with the concave side facing the front of the frame. Each cage comprisessegment shaped end members l1 and 18, several upright bars l9 arranged in an are, u and a thread guide bar 5 located at the center of the arc. Upon the bars [9 are pivotally mounted arms I, which bear at their ends bobbin supports in the form of skewers 4. The pivoted arms I permit the bobbin supports to be turned out of normal position-for exchange of bobbins, as indi- 5 cated at the middle of Fig. 2. In the drawing the bobbins are arranged in pairs, each pair comprising an' active bobbin and a reserve bobbin, with threads tied as indicated at ii. The bobbin supports may be staggered, individually or in 10 pairs, to facilitate the servicing of the creel. The drawing shows the bobbins staggered in pairs, in each of Figs. 1, 3, 5, and 7. That is to say, the two bobbins 20a which form one pair are at a higher level than the two bobbins "D, which form the other pair in the same group. The yarn from the bobbins is trained through eyes 2| in the thread guide bar 5 and through tensioners 6. The tensioners may, as usual, be fixed to the main frame, as shown at the left side of Fig. 2, or they may be fixed to the thread guide bar 5, as shown at the right side of Fig. 2.

To prevent entanglement of yarn caused by the ballooning of the payed of! yarn there are wires or rods 9 parallel with the bars I. These rods, which may be carried by pivoted arms I, have horizontal guards l0 fixed thereto. The pivoted arms enable them to be swung outwards if required, for example, for tying a ruptured thread.

The cages 2 may travel on rails 3 (Figs. 2 and 4) or they may be rigidly fixed to links I! (Fig. 6) pivoted to arms I I fixed to the frame I, and sup ported upon rollers l3 riding upon tracks I and upon the center board l5. From comparison of Figs. 2 and 4, it will be seen that the cages can be placed more closely together by laying the rails obliquely as at 3'.

With the pivoted arrangement of the cages shown in Fig. 6, enabling the bobbins to perform circular movements, the bobbins are particularly easy of access, without requiring the respective cage to be moved wholly out of alignment with the other cages. The links I! serve to limit the outward movement of the cages and also make possible a turning of the cages into a position giving convenient access to all bobbin supports.

- The construction shown in Figs. 7 and 8 enables the bottom rows of bobbins to be reached very easily, as the operative can lean over towards them. Here the rails 3" are arranged obliquely, like the rails 3' in Fig. 4 (only a portion of one side of the creel being shown), but the lower rails 3" are not directly under the upper rails, being displaced toward the left in occol'du 1 rected toward said thread guide bar, and a frame within which said cages are mounted so as to be independently movable transversely of the tier.

2. In a creel, a tier of cages, each cage comprising a vertical thread guide bar, at least three vertical skewer supporting bars equidistant from and parallel to said thread guide bar, andmeans tying said bars into a unitary oblique prism shaped body; skewers mounted in rows on said skewersupporting bars and directed toward said thread guide bar, and a frame within which said cages are mounted so as to be independently movable transversely of the tier.

3. A creel comprising a tier of cages, each cage being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side, each cage being individually movable in a direction transverse to the' tier.

4. A creel comprising a tier of cages, each cage being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side and a thread guide bar at the center of curvature of the arcuate side, each cage being individually movable in a direction transverse to the tier.

5. A creel comprising a tier of cages,-each cage being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side and a thread guide bar at the center of curvature of the arcuate side, each cage being individually movable in a direction transverse to the tier, and guards within each cage for preventing entanglement of yarn due to ballooning.

6. A creel comprising a tier oi cages, each cage being ofgenerally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side, each cage being individuallyvmovable in a direction oblique to the tier. I y

'l. A creel comprisinga tier of cages, each cage being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radilly inward from 1:; arcuate side, a frame within which said cage are mounted, and pivoted arms connecting the respective cages to said frame and adapted to guide the cages individually out of the tier by a circular movement.

8. A creel comprising a tier of cages, each cage being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side, said bobbin supports being in paired arrangement with the two supports of each pair on the same level and the pairs staggered with respect to'each other, each cage being movable in a direction transverse to the tier. i

9. A creel comprising a tier of cages, each cage,

being of generally arcuate shape on one side and having a multiplicity of bobbin supports directed radially inward from its arcuate side, said cagesall having a similar orientation to the axis of radially inward from its arcuate side but pivotally mounted so that they can be turned outward for changing bobbins, each cage being individually movable in a direction transverse to the tier.
