Claims.

This invention relates to a device for forming designs with yarn, such as the iiower and pompon design shown and described hereinafter. The principal object of the invention is to provide means for forming such designs rapidly and with uniformity. It is also an object of the invention to make it possible to change the size of the design quickly and easily.

The nature and objects of the invention will best be understood from the following disclosure in conjunction with the accompanying drawing, in which:

Fig. 1 is a side view in elevation of the tool of the invention;

Fig. 2 is a top plan view, partly broken away;

Fig. 3 is a similar view showing a different position of operating parts from that shown in Fig. 2; and

Fig. 4 is a top plan view of a typical product formed with the tool of the invention.

In the drawings, a hollow head I is provided with a recess 2 carrying a turnable disc 3 having holes 4 in which one end of a plurality of wire ngers 5 are pivoted. The ngers 5, which are bent as shown, have straight projecting ends 6 which are slidable in openings 'I in a disc or plate 8 which is secured to the head I. The disc 3 is also secured by any suitable means to a rod 9 enclosed within and coaxial with a tube I0, which serves as a handle. The outer end of rod 9 carries a knurled knob I I. Rotation of knob II and consequent rotation of rod 9 turns disc 3 and thereby protrudes the ends of fingers 5 as shown in Fig. 2 or, by opposite rotation, retracts them as shown in Fig. 3.

The top of the tool and the head I are covered by a plate or cover I2 secured as by screws I3, and diametrically opposed holes I4 are formed therein which are adapted to receive the pins Iii-I5 projecting from crosshead I6 removably secured by said pins to said cover plate. Cross- 'head I6 has a generally convex middle top portion II flanked by elevated shoulders I8. The convex portion is substantially throughout its length provided with teeth I9. The lower middle portion of said crosshead is provided with a generally concave portion 28 flanked by slots 2 I--ZI which preferably begin as narrow channels 22 adjacent the curved portion 2Q and widen into pearshaped extremities 23.

In operation, the ngers 5 are protruded, the crosshead is removed, and yarn is passed back and forth diametrically across the top plate and around the ngers 5, each passage across being usually on the next adjacent diagonally opposed ngers-ffrom the ones initially chosen-to start with. The process is repeated, the fingers being utilized progressively around the head until at least one complete series of loops is formed. If desired, this circuit may be repeated one or more times. Then a needle (not shown) is employed to gather the crossed mid-sections of yarn. Thereupon the crosshead is placed on the cover plate over the looped yarny and repeated windings, preferably of a, different colored yarn, are made transversely of the crosshead from the central concave part to the central convex part- The lower extremities of a wind are held bunched in the concave part, the middle portion of the yarn wind pass across the vertical face and back of the crosshead, and the upper end of the successive winds are held on the teeth I9 and between the shoulders I8. The shoulders prevent displacement of the yarn from the mid-section, while the teeth prevent relative displacement of the windings.k Thus the windings can be uniformly and accurately centered with respect to the central part of the loops of yarn held by iingers 5, and the mid-section of the upper winding can be built up. When suicient material for a top-knot or pompon has been wound, the end is secured with the help of a needle, which onat least some of its strokes will be passed through slots 2 I-ZI to encircle the lower part of the upper winding. vOther strokes will penetrate the mid-portion ofthe looped lower winding. When the top-knot is secured, its upper part is cut along the sides of the toothed portion with scissors. The crosshead is then removed, and, except forA any desired final trimming, the pompon is'complete. gers 5, and the whole design removed. The edges of the loops are secured or otherwise treated in a manner not involving the use of the tool of the invention.

In order to change the size of thepetals or loops of the design, the distance travelled in forming each loop may be increased by placing a spacer (not shown) between the cover plate I2 yand. the base plate 8.

We claim:

l. A tool for forming designs with yarn comprising a nat hollow casing having spaced holes in its peripheral edge, a rotatable disk within said casing carrying a plurality of wire iingers which extend radially through the spaced holes in said casing and over which yarn may be wound, a handle for rotating said disk relative to the casing for retracting said wire fingers within said casing, and a removable cross piece The knob I I is turnedvto retract the n- 3 mounted diametrically across said casing having a convexly curved serrated upper edge.

2. A tool for forming designs with yarn comprising a at hollow casing having spaced holes in its peripheral edge, a rotatable disk within said casing carrying a plurality of wire ngers which extend radially through the spaced holes in said casing and over which yarn may be wound, a:l hamile,- for, rotating said;v disk -relative to the casing-- for rei'lracting'said` wire-'ngers within said casing, and a removable cross piece mounted diametrically across said head and atA right angles to the plane of said casing...-

3. 'I'he device according to claim 1 in which said cross piece has a convexly.: curved.fserratedx1`5=`v upper edge nanked by raised shoulders.

4. The device according to..-c1aim.1 inwhch. said cross piece has a convexly curved serrated upper edge and a concave lower edgesspacedl above the casing.
