LUIVIP OR SLUB CATCHER FOR YARN-WINDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 793,084, dated June 27', 1905. Application filed December l, 1904. Serial No. 235,048.

To f1.7/ Uilm/11. fi llmfy/ (l/accru:

Beit known that I, IVILLIAM S. MILLS, a citizen otl the United States,residing at Bridgeport, in the county ot' Fairfield and State ot' Connecticut, have invented certain new and useful Improvements in Lump or Slub Catchers for Yarn-IVinding Machines, of which the Vfollowing is a specification.

My invention relates to improvements in IO lump or slub catchers 'for yarn-winding machines; and the main object of my improvement is etliciency in operation, especially with reference to the certainty ot' catching all imperfections in the yarn.

In the accompanying drawings, Figure I is a side elevation ot' my slub-catcher. Fig. 2 is a plan view ot' the same. Fig. 3 is a plan view ot' the same with the card-clothing plate turned back, so as to be out of action. Fig. a is a transverse section otl the guiding-plate on the line ,1' ,n ot' Fig. 3 with an elevation ot' the parts lying beyond the said line.

A designates the guiding-plate, that forms the base ot' my slub-catcher. It is provided with ears by means ot' which and proper screws or rivets it may be attached to the guide-bar of any ordinary yarn-winding machine and in a position to have the yarn or thread drawn tautly over the smooth or polished face 6 ofthe said plate A. This polished face of the said plate has a fiat middle portion with a rounded portion at each edge thereof.

At one end ot' the guiding-plate A there is a pair of bracket-ears 7, within which I pivot the lever 8 on the pin l5. A card-clothing plate 9 is pivoted tothe middle portion ol the said lever 8 by means of pintle 16 and lugs l0, that project upwardly from the said plate 9 near one end. The opposite end ot' the cardclothing plate 9 is provided with an adjustingscrew 1l and set-nut l2. A like adjustingscrew 13 and set-nut la are arranged in that end of the lever 8 which is farthest from the bracket-ears 7. The end ot' the adjusting- LS screw 13 bears on the top of the'card-clothing plate 9, as shown in Fig. l, whereby the said card-clothing plate may be adjusted to the desired distance 'from the top face 6 ot' the guiding-plate and also so adjusted as to be parallel to the said plate with reference to the length of the said parts. A piece of sharp-pointed card-clothing 17 or an equivalent series ot' sharp-pointed teeth is secured to the under t'ace of the card-clothing plate, as shown.

To use the slab-catcher. it is secured to the guide-bar or other part of a winding-machine, so that the thread or yarn may be drawn tautly over the top face ot' the guiding-plate A as it passes to the spool or bobbin on which it is wound. By means of the adjusting-screws l1 60 and 13 the card-clothing is adjusted to bring the plane ot' its points or teeth at agiven distance from the face 6 of the plate A when the parts are in the position shown in Figs. l and 2. This distance will be greater or less, accoi-ding to the size or thickness ot' the yarn to be wound. A gage in the form ot' a at plate and ot' the same thickness as the yarn to be wound may be used in adjusting the cardclothing to the guiding-plate, the said gage being' placed on theguiding-plate to adjust the points and removed after adjustment. The screws ll and .13 serve as stops to limit the downward movement of the outer ends of the card-clothing plate 9 and lever 8. vWhen the 75 gage-plate is to be used, the screws should be turned back far enough to be out of the way. After bringing the card-clothing plate 9 down level on the top of the gage-plate the screws can be turned down until they come to their SO bearings and the set-nuts tightened up. The gage-plate may now be removed, and the device is ready t'or use. Turning down the screw ll will raise the outer ends of the cardelothing plate 9 and the lever 8. Then turn- 85 ing down the screw 13 will raise the outer end otl the lever 1S and lower the pivoted end ot' the card-clothing plate 9. lVith the parts thus placed and adjusted, as shown in Fig. 1, the yarn passes along between the guidingplate and points of the card-clothing without obstruction so long as it is even and free from lumps or slubs. Them however, a lump or slub thicker than the regular size of yarn reaches the guiding-plate, it is caught bythe card-clothing. The operator then turns the level S and attached parts over into the position shown in Figs. 3 and 4, pulls otl' the yarn,

and breaks out the bad place. is again readjusted for winding, the lever and connecting parts are turned back again into the position shown in Figs. l and 2.

The main advantage of this Construction is the certainty of catching all the lumps or slubs, thereby insuring a clean yarn. All danger of breaking needles and such other trouble as results from the yarn not being freed from lum ps and slubs is avoided by the employment of my catcher.

I claim as my invention# l. The combination of a guiding-plate with a lever pivotally mounted on the said guidingplate, and a card-clothing plate pivotally conneoted to the said lever, and means for ad- 1 Vhen the yarn 1 justing the said card-clothing plate and lever on their pivots, substantially as described.

2. The combination of the guiding-plate With the lever pivotally connected by one end with the said guid e-plate, a card-clothing plate pivotally Connected to the said lever and the two adjusting-screws mounted near the respective ends ofthe said lever and card-clothing plate, the screw in the card-clothing plate being resisted by the guiding-plate and the screw in the lever being resisted by the cardolothing plate.
