Application filed July 5,

To all whom it may concern:

Be it known that I, HENRY N. bessern, a citizen of the United States, residing at Manchester, in the county of Hillsborough e and State of New Hampshire, have invented certain new and useful Improvements in Thread Guides, of which the following is a specification, reference being had to the accompanying drawings;

l ments in thread guides and has relation more particularly to a device of this general character especially designed and adapted -for use in spooling and it is an object of the ini vention to provide a device of this general characterhaving novel and improved means- -whereby scraping of the yarn is prevented as the same travels through the guide.

Another object of the invention is to pro` vide a novel and improved device of this general character comprising an adjuster wheel to eiect the proper setting of -the thread on the s cols.

It is also an o ject of the invention to provide a novel and improved guide of this general character which operates to prevent the making of bad spools and which com rises in its'construction a tension post whic operates, as the spool grows larger, to increase the tension on the thread and thus make a harder and better spool.

The invention consists in the details of construction and in tli'e combination and arrangement of the several parts of my improved s thread guidev whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set 40 forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to theaccompanying drawings, wherein l Fi re 1 is a fragmentary view somewhat of a iagrammatic character partly in elevation and artly in section illustrating a thread guidb constructed in accordance with an embodiment of my invention;

Figure 2 is a view partly in section and This invention relates to certain improve- I GUIDE.

partly iii top plan of the guide as illustrated in Figure 1;

yFigure 3 is 'a view in front elevation of my improved guide as herein set orth;

VFigure 4 is a sectional view taken substantially on the line 4-4 of Figure 2;

As disclosed in the accom any/ing drawings, B denotes an arm or rod suitably supported by the spooler and with which is clamped or otherwise secured a tensioning device.

The tensioning device as herein disclosed comprises two sections X and Y. The section X comprises a base block 1 provided at its forward marginal portion with an upstanding blade 2, the block 1 having its lower portion. extending beyond the inner edge of tlieblade. The section Y includes a base 3 having an upper extension 4 overlying the extended portion 5 of the base 1 of the section X and the forward portion of the base-3 and the extension 4 thereof is provided with an upstanding vblade 6 substantiall in duplicate of the blade 2. The opposedl edges of the

blades

2 and 6 have their lower portions in parallelism 'with their upper portions disposed on predetermined outward curvatures.

The sections X and Y are adapted to be adjusted one with respect to lthe other in accordance with the count or number of yarn desiredl and as herein disclosed this adjustment is elected through the instrumentality ofv the bolt 7 disposed loosely through the outer end of the base 3 of the section Y and in threaded engagement withV the opposed end portion lof the extension 5 of the base 1 of the section X, as is particularly illustrated in Figure 4. The head 7a of the bolt 7 has direct contact with the outer end of the base 3 so that when the bolt 7 is turned in one direction the section Y will be moved toward the section X. The opposed faces of the base 3 and the exten- `sion-5 are. provided with the registerin or aligned sockets' 8 in which is mounte an expansible member 10 herein disclosed as a coiled s ring encircling the bolt 7. When the bolt the sprin or expansible member 10 serves to move ne section Y in a direction away from the section X.

is rotated in the reversed direction,

. extension 5 of the base 1.

The thread from the bobbin Z or the like is dropped by the spool tender between the jaws afforded by the

blades

2 and 6 and thence to the spool S it` being understood that the sections X and Y having been irst relatively adjusted in accordance with the count or number of the thread or yarn.

In lorder to assure the maintenance of the sections X and Y in desired adjusted relation I find it of advantage to employ the holding screw 11 threaded through the base 3 and having clamping contact with the bolt 7.

Extending upwardly from the base 3 inwardly of but in close proximity tothe blade 6 is a tension post 12 which serves to prevent the thread from scraping on the right blade 6 and as the spool grows bigger, the post 12 will give an'added tension to the thread resulting in a harder and betten s ool.

pExtending outwardly from the base 1 adjacent the outer end thereof is an arm 15 and extending inwardly from the arm 15 and carried thereby is a stub shaft 16,1 said shaft having its outer or free end terminating in close proximity to the free end of the Eccentrically mounted upon the st-ub shaft 16 is an` adjustable wheel 17 the pe-i riphery of which being grooved to receive a thread.

Threaded upon the stub shaft 16 at opposite sides of the wheel17 are the clamping nuts 18 which serve to hold the adjuster wheel in its different positions about the shaft 16. By proper rotation of the wheel 17, a proper setting will be eiected of the thread with respect to the spools, the wheel being adjustable to vary the path of the f thread through the guide to minimize wear.

From the foregoing description it is thought to be obvious that a thread guide constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my linvention issusceptible of some change and modification without departing from the principles and spirit thereof1 and for this reason I do not .wish to be understood as limiting myself to sections being Lacona? aligned with the inner edge of one of the blades.

2. A guide of the class described comprisaligned with the inner edge of said blade.

3. A guide of the class described comprising two sections, means for adjusting the same one with respect to the other, said sections being provided with upstanding blades providing jaws between which a thread is adapted tobe disposed, an upstanding guiding ost carried by one of the sections, and vertlcally adjustable means carried by one of the sections for setting the thread, said vertically adjustable means and a side of the post being substantially aligned with the jaw between the blades.

4. A guide of the class described comprising two sections, means for adjusting the same one with respect Ito the other, said provided vwith upstanding blades provi ng jaws between which a thread lis adapted to be disposed, an upstanding guiding post carried by one of the sections, and an eccentrically mounted wheel carried by one of the sections, said wheel and a side of the post being substantially aligned with the jaw between the blades.

5. A guide of the class described comprising two sections, means for adjusting the same one with respect to the other, 'said sections being provided, with upstanding blades providing jaws between which a thread is adapted to be disposed, an u standing guiding post carried by one of tliie sections, and an eccentrically mounted wheel carried by one of the sections, in advance of the blade carried thereby, said wheel and a side of the post being substantially aligned with the jaw between the blades.

6. A guide of the! class described comprising two sections, means for adjusting the same one with respect to the other, said sections being provided with upstanding blades providing jaws between which a thread is adapted to be disposed, an upstanding guiding post carried by one of the sections, an outstanding arm carried by one of the sections, a stub shaft carried by said arm, an adjuster wheel eccentrically mounted on said stub shaft, and means for holding said wheel a ainst movement about the stub shaft, said w eel and a side of the post being substantially aligned with the jaw between' the blades.

7*. A guide of the class described comprising a member provided with a slot through which a thread is adapted to be disposed, an

upstandng guide post carried bythe member and having a side thereo substantially aligned with an edge of the slot, and means carried by said member to vary the path of the thread through the slot.
