Patented Get. 22, 1929 UNITE STATES JAMES R. WELTON, OF SUB-ANTON, PENNSYLVANIA THREAD GUIDE App1icati0n.fi1ed December 6, 1928. Serial No. 324,179.

This invention relates to improvements in thread guides, and particularly to a novel guide to be employed with a silk thread cleaner.

My present device is designed to guide the silk or cotton through the cleaning blades, and eliminate the wear on such blade's, which are usually made of metal. With my device, which is preferably formed of porcelain, the

silk rides on specially shaped surfaces at the front of the device, and the back portion of the guide is shaped to distribute the silk on the bobbin, and provide a better bobbin, as this guide prevents the silk at the'rear of the 1:; guide from moving back and forth.

One of the objects of the invention is to furnish a thread guide preferably composed of vitreous material, porcelain for example, and of substantially inverted U-shaped in side elevation, the top of the guide having a longitudinally extending V-shaped groove which merges into a vertical slot that is de signed to receive the thread and guide the same through the cleaner. I

A further object is to furnish a thread guide of this character, having a front extension provided with a U-shaped surface that is curved to facilitate the riding of the silk back and forth, as it is coming off of the bobbin or skein, and passing to the cleaner.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, my invention consists in the novel features hereinafter des-.

cribed in detail, illustrated in the accompan' ing drawing, and more particularly pointed out in the appended claims.

Referring to the drawing,

Fig. 1 is a side elevation of my improved guide shown applied to a thread cleaner.

Fig. 2 is a front elevation of the same.

Fig. 3 is a top plan view.

Fig. 4 is a rear elevation of the guide.

Fig. 5 is a horizontal sectional view taken on line 5-5 of Fig. 1.

Fig. 6 is a vertical sectional view of a detail on line 6-6 of Fig. 2.

In the drawing, 1 designates the base or frame of a thread cleaner provided with cleaning'blades 2 which may be moved toward or away from each other to vary the width of the slot 8 between the blades, A silk or cotton thread may be fed from a bobbin or skein through this slot, and then be wound on a second bobbin and as is usual in such devices, the blades clean the thread as it is being wound on the quill or bobbin, preparatory to weaving. The blades catch or remove snarls, bad knots, wax, gums or the like.

It is the purpose of my invention to provide a novel guide for use with such cleaners and one which will eliminate the wear on the cleaner blades and provide a surface on which the thread may ride and another surface to facilitate the ditribution of the silk on the quill or bobbin the last mentioned surface being formed on the wall of a narrow slot which will prevent the thread from whipping back and forth on the cleaner blades as it is being wound on the bobbin.

As shown in the drawing, this improved guide 4 is preferably made of some vitreous substance such as porcelain, and in side elevation this guide is of inverted U-shape with the front leg 5 extending downwardly below the rear leg 6 and provided with a pin 7 to be inserted through a hole in the base 1, for securing the guide in position. The guide is a one-piece structure, so that it'may be readily installed or removed.

A narrow longitudinal slot8 is vertically arranged "through the device and extends through the top or crossbar 9, as well as through the legs, and the cross bar has a longitulinally extending upwardly flaring or V-shaped groove 10 to facilitate the introduction of a thread into the slot. At this point it may be noted that the slot in the guide is in alignment with the slot between the cleaning blades, and that the walls of the slot of the guide receive any whipping actionof the threads, and prevent such action being applied to the cleaning blades.

'lhe front ends of the side walls of the groove are curved as shown at 11, and these curved surfaces merge into vertically disposed curved surfaces 12 that join the front ends of the walls of the guide slot to the front surfaces 13 of the'front leg.

An extension 141 is provided at the extremity of the front leg, and this extension projects forwardly and is provided with a U-shaped surface 15 that is curved from the guide slot to the side edges 16 of the extension, as well as to the edge 17 of the extension, and due to this formation, it will be understood that the thread passing from the skein or bobbin through the cleaner, may readily ride back and forth on this U-shaped curved surface without interference; On the other hand, the parallel walls 18 at the rear end of the slot merge into a plane vertical transverse surface 19, formed on the rear legyand as the slot in the rear leg is only about onesixteenth of an inch wide, it willbe seen that the thread in leaving the guide, will be pre vented from moving back and forth, so that it will be more evenly distributed on the re-' ceiving bobbin.

From the foregoing it is believed that the construction, operation and advantages of the invention may be readily understood by those skilled in the art, and I am aware that various changes may be made in the details disclosed without departing from the spirit of the invention, as expressed in the claims.

What I claim and desire to secure by Letters Patent is:

1. A thread cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, said legs beingspaced apart to permit the insertion of a thread cleaner between the same.

2. A thread cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, the cross member having a longitudinally extending substantially V-shaped groove merging into said slot, said legs being spaced apart to permit the insertion of a thread cleaner be tween the same.

3. A thread cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, the rear surface of the rear leg being in a plane at right angles to the walls of said slot, said legs being spaced apart to permit the insertion of a thread cleaner between the same,

4. A thread cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, the front leg having vertically disposed curved surfaces which join the front surface of the front leg to the surfaces of the side walls of the slot, said legs being spaced apart to permit the insertion of a thread cleaner between the same.

5. A thread cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, the cross memher being provided w1th a longitudinally extending horizontally disposed groove, having curved surfaces at its forward end merging into the front surface of the front leg, said legs being spaced apart to permit the insertion of a thread cleaner between the same.

6. A thread'cleaner guide of substantially inverted U-shape in side elevation, and having a front leg, rear leg and cross member through which a narrow slot extends, an extension projecting forwardly from the front leg, said extension having a U-shaped curved surface merging into the walls of said slot, said legs being spaced apart to permit the insertion of a thread cleaner between the same;

7. A thread guide for use with thread cleaners, formed of a single piece of a vitreous substance, and of substantiallyinverted U-shape in sideelevation, said guide having front and rear legs joined by a cross bar, the guide being provided with a longi tudinally extending vertically disposed slot which passes through the l'egs and acres the bar, said cross bar having a longitudinally disposed upwardly flaring groove merging into said slot, the rear surface of the rear leg being arranged at right angles to the walls of the slot, and the front leg having an extension and curved-surfaces to permit a thread to ride back and forth on the front leg-and into said slot, said legs beingspaced apartto per mit the insertion of a thread cleaner between the same.
