Theguidewhich;I have here constructed fulfillsthis requirement althoof course, it may be used in other spinning machines, such for instance as ringspinningor the like where greater spa cm e had n ,l I have shown an'illustration of this invention in connection with a mule spinning frame, in

natedrlo and bearingblocks 11, 12; 13, etc., are provided for the .lower fluted rolls, while along the overarm 16 there are provided guide blocks 17 18, 19,,etc.,,f or the upperrolls in eachof the pairs of rolls. Thefront pairs of rolls are desig- 40 nated 22 and. 23 -,-and':a= pair of rolls just back of the front rolls are designated 24 and'25, and it is between these two pairs of rolls that my guide is positioned. These rolls run with their surfacesjust clear; of. each other, as illustrated more 45 clearly in Fig. 1' where they are shown in'connection withvavmule spinning machine. 7

Between the Working surfaces of each of these. lower r-olls 22, there is'a reduced portion 26, at a point beneath the overarm, while the upper roll is short, seerfor. instance roll..25 in Fig. 5, with its trunnionsfiZ'l; as mounted'tin suitable bearing. blocksor. guides which are carried by the overanni fii gitjspacedapoints,such as at the overarmsllfi,

I provide a supporting member designated generally 30 which is constructed by bending it up from sheet stock to provide a bottom wall 31, side walls 32 and 33, connected by a top wall 34 and leaving a space 35 between the side walls which may be adjusted by moving the side wall 33 towards the side wall 32 by bending it at the top wall and which is permitted by the free edge 36 which may be slid. inwardly along the bottom wall 31. A square opening thru each of the side walls, designated 3'7, is provided for receiving the overarm 16 while a threaded opening 38 is provided for receiving a set screw 39 to extend down into engagement with the topof the overarm 16 for binding the support 30 in position. I

The yarn guide member consists of a thin, elongated strip of sheet stock 40 which is notched as at 41 and 42 and drawn slightly forwardly to provide a smooth rounding surface for the entrance of the yarn and for "confining it so that any straggling fibers will be forced back into the main strand as it travels thru the machine. At the ends of this body portion of the yarn guide I have formed fingers 43 which extendinto the space 35 in the support. A notch as at 45 may be provided for lightening up the structure. The fingers 43 will be sufliciently short so that with the top rolls-removed, the support 30 may be first placed on the overarm and then by diagonally placing the'support or guide 40 with first one end in the support and then the other,the yarn guide may be placed in position. v

In supplying the supporting member 30, I usually leave the walls 32 and 33 close together so that they will bind the fingers 43 when first positioned into these supports. However, as I position the supports in place I may take a screw driver and place it in the opening 35 and. by twisting this screw driver open the support so that the guide walls 32 and 33 are positioned the correct distance apart for maintaining the desired guiding action on the yarn guide as it is moved by the oscillation of the threads.

It will, of course, be understood that one or any desired number of slots or notches 42 or 41 may be placed in the guide '40 depending upon the number of ends which are located between two adjacent places of support, such as the overarm. a

By this construction a very simple arrangement of oscillatory guide is formed which may be extremely simple and economical to manufacture and assembled in position on the spinning machine.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:
