SLUB CATCHER Filed Sept. 14. 1929 INVENTOR 00 45. 6 9651900671 ATTORNEY Patented July 7, 1931 UNITED STATES PATENT OFFICE LOUIS B. HASBROUCK, OF ELMIRA, NEW YORK, ASSIGNOR TO ECLIPSE TEXTILE DE- VICES, INQ, OF ELMIRA, YORK, A CORPORATION OF NEW YORK SLUB CATCHER Application filed September 14, 1929.

This invention relates to slub catchers, and aims to provide a slub catcher particularly adapted for use on worsted yarns.

A slubcatcher embodying the invention has a spring blade mounted so that it is drawn in to sever the yarn by the engagement therewith of slubs or other projections on the yarn.

The device provides for positioning slubs or other projections on the yarn so as to engage lo the blade, and for accurate adjustment of the blade for use with different sizes of yarn.

An illustrative embodiment of the invention is shown in the accompanying drawings, in Which:

Fig. 1 is a side elevation;

Fig. 2 is an end elevation; and

Fig. 3 is a plan view.

The slub catcher illustrated has a frame 10, from which projects a curved bed 11 across and partly around which a traveling yarn A is drawn, as shown in Fig. 1. The bed 11 is made of hard material, such as porcelain, and may be cylindrical as shown, although the shape of the lower part of the bed is, of course, immaterial to the action of the device. On the outer end of a slightly resilient adjustable bracket or arm 12 secured to the frame 10 is mounted a plate 13 which is transverse to the line of travel of the yarn and to the upper surface of the bed. The plate 13 contains a bend near its outer edge so that its outer portion 14 is inclined toward the direction from which the yarn is traveling, while its main body 15 is either less inclined in said direction or substantially perpendicular to the line of travel of the yarn. Against the outer portion 14 of the plate 13 is secured the outer end of a spring blade 16, so that this blade tends under its own resil i iency to move away from the main body 15 of the plate 13 and to assume a position in which it is inclined toward the direction from which the yarn is traveling. Such outward movement of the blade is limited by a stop 17 which extends from the lower portion of the plate 13, and may be formed by a frame-like projection at the lower edge of the plate as shown. The blade 16 contains a bend near its lower edge, so that, when it is in its normal pos1- tion against the stop 17 the portion 18 of the Serial No. 392,619.

blade near its lower edge is substantially perpendicular to the line of travel of the yarn. The lower edge of the blade is preferably sharpened as shown.

The normal distance between the edge of the blade and the bed should be just sufficient to permit the yarn to travel freely between them. Accurate adjustment of this distance is obtained by adjusting the position of the plate 13 by means of a screw 19 threaded into the frame 10 and having a head bearing against the arm or bracket 12. A compression spring 20 holds the arm or bracket 12 in firm engagement with the head of the screw 19.

In the operation of the device, slubs and other projections on the yarn are turned upwardly by the drawing of the yarn across the curved bed 11. Such slubs and projections, therefore, strike the lower edge of the blade 16, whereupon the travel of the yarn draws the blade inwardly towards the plate 13. Because of the inclination of the blade and the portion 14 of the plate 13 to which it is attached, this inward movement of the blade swings its lower edge against the bed so that it severs the yarn.

W hat I claim is:

1. A slub catcher, comprising a bed across which a traveling yarn is drawn, and a bent resilient blade having a body portion inclined towards the direction from which the yarn is traveling and an end portion substantially perpendicular to the line of travel of the yarn and terminating in an edge slightly spaced from said bed.

2. A slub catcher, comprising a bed across which a travelin yarn is drawn, a rigid plate extending toward said bed and having an outer portion inclined towards the direction from which the yarn is traveling, a resilient blade having one of its ends secured against said inclined portion of said plate and its other end opposed to said bed, and a stop on said plate limiting movement of said blade away from the plate and the bed.

3. A slub catcher, comprising a bed across which a traveling yarn is drawn, a rigid plate extending toward said bed and having an outer portion inclined towards the direction from which the'yarn is traveling, a resilient I blade having one of its ends secured against said inclined portion of said plate and its other end opposedto said bed, a stop on said plate limiting'moveinent of said blade. awa
