13 Claims.

This invention relates to new and useful improvements in spinning machines, and more particularly to a thread and roving guide especially adapted for use on spinning machines in the manufacture of bourette and novelty yarns, the

same being a continuation in part of my to Other objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary top plan view showing the roller assembly of a spinning machine equipped with the improved guide means.

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a perspective view of the guide unit.

Figure 4 is a section on the line 4-4 of Figure 3. V Figure 5 is a section on the line 5-5 of Figure 3.

to Figure 6 is an elevational view ofan attachment adapted to be employed in place of the forked leg 32 when certain kinds of roving are used, especially roving of a finer gauge.

Referring to the drawings wherein like nu- 40 merals designate like parts, it can be seen in Figure 1, that numeral 5 denotes a bank of rollers consisting of the back roller 6 the front roller 7 and the intermediate roller 8 overlying corresponding rollers 9, I0 and II, respectively.

45 As shown in Figure 2, the guide is generally referred to by numeral I2 and is mounted on the usual roving transverse motion bar [3. The unit l2 consists of the post M, the lower portion of which is reduced as at I5 to define shoulders This reduced portion l5 has the opening i1 therein through which the bolt 13 extends and is equipped with the nut l3. This bolt l8 extends through the bar 13 and firmly secures the post 14 in the position sub- 55 stantially shown in Figure 2. This post l4 consists of a pair of interlapping sections a-b connected by a bolt and slot connection 0.

A substantially square-shaped block 23 is adapted to rest upon the shoulder 2| at the upper end of the post 14 which is defined by the 5 provision of the reduced extension 22. The lower edge portion of the block 20 has the elongated slot 23 therein, through which extends the screw 24, this screw passing'through a washer 25 bearing against the forward side of the block 20. 019- viously, by loosening the screw 24, which is driven into the reduced extension 22 of the post [4, the block can be adjusted in a lateral direction and secured in the adjusted position by tightening the screw. 15

A pair of eye members or bushings -26 extend through the upper portion of the block 20 and narrow slots 21-21 incline upwardly from i the side edges ofthe block to extend into the eyelets or bushings 26. Obviously the yarn threads 20 can be easily inserted into these eyelets by way of the slots 21, thus eliminating threading of the eyelets. This will save considerable time on the part of the attendant.

As shown in Figures l and 2, the yarn threads. 5 28-28 extend downwardly from the spools (not shown) through the eyelets 23-23, and downwardly over the roll' 8 and between the rolls 1 and [0.

The roving (see Figure 2) is denoted by numeral 29 and extends from an upward position,

' downwardly under the rail 30 and passes between the rolls and forwardly to bunch with the threads 28-28 as suggested in Figure 2.

Frequently this roving 29 shifts on-the rolls and does not merge withthe threads 28-28 intermediately. This results in the roving being exposed on the finished yarn, which, of course, is improper. In consideration of this, the roving guide element generally referred to by numeral 3lis employed.

This guide 31 consists of the arcuate-shaped member 34 formed with the down-turned bifurcated ear 35 through which the screw 31 is disposed. This screw is threadedly disposed into a threaded opening in the post section a.

The lower end portion of this arcuate-shaped member 34 is formedwith the slot 33. A leg 32 is apertured at its upper end to receive the bolt 32a which passes through the slot 33 and is equipped with a nut whereby and in complement with the bolt 32a, the leg 32 can be clamped in the desired adjusted position against the lower portion of the arcuate-shaped member 34. The lower portion of this leg 32 is forked as at 33 to receive the roving 29, as clearly shown in Figure 2.

This forked leg 32 is preferably employed when coars or heavy roving is being utilized, but when finer gauged roving has to be employed, it is preferable that the leg 32 be detached and the trumpet substitute therefor. This trumpet 40 has the opening 42'at its upper end to accommodate the bolt 32a and the roving guide opening 43 at its lower end.

Thus it can be seen, that with either the forked leg 32 or the trumpet 40 in use, the roving will be guided to meet the threads 28 at a centralized merging point to the end that improper twisting of the threads and roving will be eliminated which at present results in exposure of the roving in the resultant yarn.

The various adjustments afforded by reason of the extensible parts are adopted to the end that this appliance can be employed on various makes and sizes of spinning machines.

Obviously, the eyelets 26 can be of porcelain or some other suitable material to the end that there will be the least amount of friction possible to which the threads 28 must be subjected. and this is also'true with respect to the roving passing through the eyelet 38.

;While the foregoing specification sets forth the invention in specific terms, it is to beunderstood that numerous changes in the shape, size and materialsgmay be resorted to without departing from the spirit and scope-of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:
