0 CHATTANOOGA, TENNESSEE, A CORPORATION or SLUB CATCHER.-
Application filed April 23, 1928. Serial No. 272,325.
My invention relatesto slub catchers, and
it is an object of the invention to provide a device which will catch slubs above a predetermined size, and will operate to stop the travel of the yarn when av slub larger than a predetermined size is encountered.
The device shown in this application closely resembles thatshown and described in my co-pending application Serial Number 672, 655, filed November 3, 1923, and is acontinuation in part of that application.
Referring to the accompanying drawings which are made a part hereof and on which similar reference characters indicate similar parts,
Figure 1 is a plan view of the invention,
Figure 2, a view in elevation,
Figure 3 a section on line 33 of Figure 1, I Figure 4, a section on line 4.l of Figure 1,and
Figure 5, a detail viewshowing the slub catcher plate.
In the drawings reference character 10 in dicates a support having an opening and a set screw 11 projecting into the opening by means of which the support may be secured to a rod on a spooler or other textile machine. Thesupport may be formed in various ways, that illustrated being a form which I consider desirable. Atthe right hand or for ward end it has a projection 12 providing means for guiding the yarn into'a notch 13 from which it passes backover the flat upper face of the support underneath a tension disc 1 1 and a slub catching plate 15.
The tension disc 14 is rounded on its under side for easy entry of the yarn beneath the disc and supported for rotation about a post 1 1. An arched guide 16 extends over the disc and post. 'The point17 of said guide preferably extends below the upper face of the disc. It will be seen that this provides a quick and easy method of entering the yarn under the disc, since the yarn may be laid on any part of the arch and slid down along the same, whereupon it will automatically slip under the disc.
The arch 16 is fastened by a set screwlS to a bar 19 in the form of a leaf spring, which is secured by a bolt 20 on an elevation 21 at one corner of the support 10. Preferably as hereshown, the upper and under surfaces of the elevated corner section form parallel oblique surfaces and the spring has an oblique part to correspond therewith, the main part tioning the same. I
of the spring being approximately horizon tal. The left end of the spring is free to move to a certain extent, such movement being limited by a screw 22 passing through an opening in the spring into the support 10. Near this support is a bracket 23 having a hole through which the spring bar 19 passes, a bracket being adjustably secured thereto by setscrews 24. V
At the end of thebracket-23 remote fron'i the spring support there is a pair of depending'arms 25 through which the pivot pin'2G passes by means of which pivot pin the rectangular slub catcher 15 is supported on the bracket. The slub catcher 15 hasa' notch or point just beneath the pivot 26. IThe'screw 22 forms a. rough adjustment for limiting the upper position of the slub catcher, while the screws 24 form a fine adjustment'for posi- Tn the use of my device the disc 14; and the guide 16 are positioned as shown in the drawings and the slub catcher is set at a distance" from the sup-port corresponding to the thickness of the yarn. The yarn is then entered through the notch 18, laid on the arch 16 and slipped under the tension disc 14 and the slub groove-15 extending across its face at a catcher 15. 'As the yarn passes over the face i of the support it will rotate the disc in known. manner and the knots by which the yarn is tied together will slip under the slub catcher between the face of the catcher and the face of the holder 10. Loose fluffs on the yarn will be pulled off by the disc and the plate 15, if
' the quantity is small. and if it does not adhere too tightly to the yarn. Any slub of suflicient size to be objectionable to the yarnwill cause the plate to tilt aboutits pivot 26 and to catch the yarn so as to break it. Thereupon, the slub may be removed and the yarn ends tied to-, gether, after which the winding or other operation may be resumed.
The device ofmy invention is not intended to stop the thread or yarn upon the appearance of any and all inequalities, but only upon to make trouble in subsequent operations. A v singleknot Wlll ordinarily not be objectionable, such knots being necessary for the reason that the yarn from a number of spinning bobbins is'wound on a single spool. A single knot willlift applicants pivoted plate have found under certain circumstances that a plate rigidly secured as the plate 15 will operate. Under these:circumstances the long objectionable slubs are caught by frictional contact between a surface of the plate 15 and the face of the support 10. However, i find the pivoted plate most satisfactory and is the form generally used.
It will be obvious to those skilled: in the art that various changes may be made in my device without departing from the spirit of the invention, and I, therefore, donot limit myself to what is shown in the drawings and described in the specification, i it only set forth in the appended claims.
i Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:
