SPECIFICATION forming part of Letters Patent N 0. 729,901, dated June 2, 1903.

1 Application filed October 10, 1902. Serial No. 126,671. (No model.)

Jrermany, have invented new and useful im provements in apparatus for continuously operating spinning-machines for arresting slots, of which the following is a full, clear, and exact specification.

The object of the present invention is an ap parat-us for continuously operating spinningmachines for arresting thick parts of the thread or twist, which device is applicable for all thicknesses (numbers) of the thread or yarn and makes use of the well-known arrangement of guide-slots. The device is, however, new, inasmuch as the said threadguide slots, tapering to the rear, are placed upon an adj ustably-arranged cross-plate provided alternately with elevations and depressions, 011 the crests of which elevations saidslots are arranged so that this slotted plate when adjusted to the required diameter of the thread will not only arrest any sidewardly-projecting fibers, but will also break off the thread at any knots or thickness at the slots, and will, moreover, collect the broken thread ends which continue to be delivered in its depressions, so that these ends do not fall down upon the spindles or become tangled and spun together with the other threads or yarn.

It is essential that the slotted plate should be properly adjusted for the thickness of the delivered threads of the spinning-machine and, namely, so that the threads in their passage through the slots remain continuously in contact with the edges thereof without actually rubbing on them.

In the accompanying drawings, Figure 1 shows in side elevation the front part of the spinning-machine, which is provided with the invention and of which the parts connected with the said invention are illustrated more or less diagrammatically. Figs. 2, 3, and L illustrate in plan, front view, and cross section the slotted plate forming the essential part of this invention.

Referring first to Fig. 1, a a indicate the thread-delivery rollers of the spinningmachine, from which the threads passing through the usual eyes I) pass to the spindles.

(Not shown in the drawings.) Between the rollers a and the eyes I) the device of the present invention is inserted. This consists, essentially, of the metal plate 0, placed transversely to'the direction of the threads and formed in this instance of corrugated tinplate, Fig. 2, reinforced behind by means of a bar (Z and supported by the bracketse from the shaft f.

I11 consequence of its corrugation the crossplate 0 possesses alternateelevations and depressions. At the crest of each of these elevations and along thesame is arranged a slot which is open to the front and graduallycontracted to the rear, Fig. 3. These slots serve as guides for the threads delivered from the rollers a. The front edge of the slotted plate 0 is preferably provided with an edging of plush g which is secured firmly thereon by means of a row of holes h and is designed to collect the fibers which accumulate in the depressions of the plate a and prevent them from falling down upon the spindles.

The slotted plate 0 can be adjusted according to the requirements by turning the shaft f. This is requisite in order to admit of the passage of threads of various strength or fineness, and this while retaining the loose contact of the threads with the edges of the slots. If the slotted plate c is adjusted for a given size or number of thread and there occurs in the thread a flaw, such as a knot or a thickening, and this reaches the respective slot of the plate, the knot is arrested, the thread breaks, and the continuously-delivered thread passing from the rollers a collects in a collecting-depression of the plate 0. It cannot, therefore, fall down upon the spindles or be tangled with any other thread. 011 the other hand, if the loose filaments projecting sidewise arrive on the passage of the thread through the slot 9, on the edges of which they have a slight contact in consequence of the adjustment, they will also be stopped and be collected in the depressions, so that the thread is at the same time cleaned to a certain extent.

In the machine illustrated the guide-eyes b, Fig. 1, are movable vertically, being placed 011 a bar 1', which can be moved verticallyin grooves upon the machine-frame for the purshaft Z, revoluble by hand.

p0se,well known, of regulating the swelling of the threads. The said bar 2 is supported upon two lever-arms 7c, which are placed upon the This shaft bears at determined regular intervals the arms m, which by the links it are compulsorily connected with arms 0 upon the shaft f of the slotted plate 0. A slot-anchpivot connection 19 z admits in the well-known manner of the adjustment of the working length of the links 01. Further, the shaftlcarries a ratchet-wheel 7*, into which the catch 8 engages. In this case the adjustment of the slotted plate 0 to adjust the width of its guide-slots to the fineness of the delivered thread is effected after loosening the slot-and-pivot connection 19 z. This connection is tightened again when the plate 0 has thus been adjusted, whereby the guideeyes b occupy their lowest position. Themachine being set into operation when the guideeyes I) are raised by rotating the shaft Z, carrying the lever-arms 7c, the slotted plate 0 by the agency of thelevers m n 0 sinks from its adjusted upper position (indicated in dotted lines) to that shown in f nll lines, so that during this motion of the guides Z) the delivered threads are guided always at substantially the same slot width, although they are some what pushed away from the shaft f when the guide-eyes Z) move upward.

If the thread guide eyes I) are fixed im- 1novab1y,the above-described connection with the slotted plate 0 becomes, of course, unnecessary.

What I claim is' 1. In a continuously-operating spinning machine an apparatus for arresting thicknesses of the delivered threads, consisting of an adjustable cross-plate formed with alternate elevations and depressions and rearwardly-tapering thread -guide slots on the crests of these elevations, the adjustment of said plate allowing the width of the guideslots to be adjusted to the number (fineness) of the delivered thread for arresting thick parts thereof and formed to catch in its depressions the broken threads which continue to be delivered by the spinning-machine, substantially as set forth.

2. In a continuously-operating spinningmachine, vertically-movable thread-guide eyes, an adjustable cross-plate formed with alternate elevations and depressions and rearwardly-tapering threadguide slots on the crests of these elevations for the purpose described and connecting means between said eyes and cross-plate arranged so as to automatically move this latter relatively to the movement ofthe threadguide eyes andtohave always the threads guided at substantially the same slot width, as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
