IMPROVEMENT IEN' YARN-GUIDE AND CLERER.

The Schedule referred to in these Letters Patent. and making part of the sam To all whom t't may concern:

Be it known that we, A; O. DAKIN, of Clinton, and J. D. BUTLER, of Lancaster, both in the county of Worcester, and State of Massachusetts, have invented a new and improved Yarn-Guide and Clearer; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure lf-is a front View;

Figure 2, a side view;

Figure 3, a View of movable plate A, fig. l, as decached.

Figure 4, a front view of a modified form ofthe invention Figure 5, a side View ofthe modified form; and

Figure 6, a top view of the modified form.

In the process of manufacture of yarn or thread, it is necessary at certain stages topass it through a narrow opening, in order to clear it of lumps, or loose iibres, that may be clinging to it. This opening should be of a width corresponding to the s ize of the yarn.VV To secure the means of varying thistwidth of opening at pleasure, to correspond with the dierent sizesoi' yarn used, in an improved manner, is the object of our invention.

In figs. l, 2, and 3, B represents the stem of the other part of the spooler, reel, or warper.

The thread passes between the edges a a and c c, of the plates A and O, as shown by the red lines.

These plates may be of steel, and O is riveted to -D, at c c, `while A` slides upon D,Ybetween the shoulder Z el and the edge c' c', of C, as shown.

When A is set in the desired position, it is held in place bythe screw E, which passes through a slot in it, and is screwed into D.

When E is loosened, and A is slipped up or down between l l and c c', the width of the opening between a a and c c, is increased or diminished.

It is obvious that the angle between c c and c c", must match that between a a and a a. .Now this angle may give so little variation from a straight line, that a certain movement of A, up or down, shall produce a still smaller one of widening or narrowing the space between the plates in which the threads run.

By this arrangement, we are able to adjust, with thread, because it is exaggerated, and so more'easily measured, in the upward or downward movement of A.

It has been customary to have A mo`ve in slides at right angles to the edges a a and c c, in which case it has been necessary to set the movable plate bythe width of the opening as directly measured.

It was also inconvenient or undesirable to Widen the clearer so much as should be necessary to make these thread runs, instead of at a right angle, as has been common heretofore.

It is not necessary that A should bear upon both edges c c' and (l (l, as one of these would answer if care were taken to keep A against it, when the. screw E should be tightened.

The modified form, shown be easily understood.

The yarn is shown as running up from the. other side, and the movable plate bears only on the side adjoining d' d. It is symmetrical in its shape, so that when the thread has worn into the one edge, it can be turned over, and the edge, which before ran upon d d', be used for the yarn to bear against.

. The iixed plate C', instead of being riveted on, as

in figs. 4, 5, and 6, will in the first arrangement, is screwed on after being set in position to match the inner edge of A. It can be turnedA end for end when worn by the thread.

The holes H are for wires, such as have been heretofore used to carry the yarn in between the plates, if it shall not be dropped directly upon these plates.

If desired, d d, in figs. l and 2, can be run furtherk up, so as to give a longer bearing-edge on the one side.

Both of the guide-plates might be moved, in adjusting the opening between them for the thread, if desired, instead of only one, as shown.

It is clear that there isa great variety of shapes which the invention may take. But without regard to particular details, We include in it the combination of two guide-plates, one or both of which shall have a movement oblique to their edges between which the thread runs.

' We have spoken ofthe invention only as a clearer; it may also serve as a guide for the yarn, as other styles of clearers have. f

The invention is not confined to the use of any par tioular material for the yarn.

We claim the combination of the guide-plates A and O, or their equivalents, adjustable by a movement of one or both, oblique to the edges between which the yarn runs, substantially as and for the purposes described. l
