S 'EPAR ATOR MECHANISM FOR RING-SPINNING FRAMES.

SPEGIFIGATION forming part of Letters Patent No. 527,389, dated October 9, 1894.

Application filed June 6 1894:- Serial No. 5 0 N m l-i To all whom it may concern.-

Be it known that I, ALFRED HITCHON, of Accrington, in the county of Lancaster, England, have invented certain new and useful Improvements in Separator Mechanism for Ring-Spinning Frames, of which the following is a specification.

My invention has reference to the separator plates used to check ballooning or interlashing of the bobbin threads in ring spinning frames, and it consists in an improved construction, arrangement and mounting of the parts whereby the space occupied by the separator and its attachments is diminished, and the separator can easily be thrown into and out of position.

My improvements can best be explained and understood by reference'tothe accompanying drawings in which-- Figure 1 is a cross sectional elevation of so much of a ring frame as needed to illustrate my invention. Fig. 2is a plan of aportion of the ring rail.

In the drawings, A represents the drawing roll stand; B, the ring rail; 0, the spindle rail; D, D, the lifting pokers which pass therethrough; E, the usual tin rollers for driving by cord or belt the spindles; F, F, the thread guide boards. These parts are organized and arranged to co-operate in the usual known manner, and require no further explanation.

In carrying my improvements into effect I form in the back of the ring rail a longitudinal groove or concave a in which is placed the shaft or rod b on which the separators are mounted-said rod being there held by bearing straps 0 located at convenient intervals apart. The rod or shaft is capable of a movement of rotation or partial rotation, and I prefer to form it in lengths corresponding with the sections of the ring rail so that the separators for each rail section may be operated independently of the others.

The separators may be loosely mounted on their rod or may be fixed thereto. Each separator is in the form of a blade G, which is formed by casting, stamping or in other convenient manner, and may be solid, perforated or (as shown) in the form of a grid. The blade projects between two adjoining spindles, and has a downwardly extending shank g, terminating in a tubular boss 9 through which the rod b is passed-the ring rail being recessed at the point where the boss comes so as to permit the latter to lie partly within it. Just above the boss is a forwardly projecting stop 9 which by bringing up against the ring rail prevents the separator from falling too far forward.

I affix to the roller beam A a'downwardly projecting stop plate or plates H, back of the separators, this stop plate being inclined, concaved or curved on its front face as shown in such a way that while acting as a stop for the separators when the ring rail is down and the separators are thrown back for doffing as indicated in full lines on the right of Fig. 1, it will, when the rail is raised act to throw forward the separators into working position, as indicated in the intermediate dotted line position on the right of Fig. 1. On the left side of the ring frame in Fig. 1, is shown a partly filled bobbin of yarn with its thread being delivered from the drawing rollers and passing through the thread guide to the bobbin on which the yarnis wound during the spinning operation. The separator is here shown in position for preventing the threads of any two bobbins from interlashing.

The downwardly projecting shank of the separator is of such length as to always maintain the blade itself at a sufficient distance from the ring traveler to allow the rings to be placed in the closest possible proximity to each other, that the working of the travelers upon two adjoining rings will admit of. The blade furthermore is always maintained ata sufficient distance from the rings and ring rails to enable the attendant to easily finger or manipulate the ring travelers when piecing up or handling the threads. The blades thus located, during the ascent of the ring rail, may at times rise above the thread guide board F. As this board is in their path, I form in it notches or slots f for the passage of the blades. In the topmost dotted line position on the right of Fig. 1, one of the separator blades is represented in the elevated position, partly received in the slot formed forits passage in the thread guide board. By this construction I am enabled to materially increase the height of the separator plate, and thus to enhance its efficiency.

Having now described my improvements,

what I claim; and desire to secure by Letters Patent, is p 1. In a ring spinning frame, the combination with the ring rail and the separators hinged thereto, of the curved or inclined stop plates H, located in rear of the separators and secured to astationary part of the frame,- substantially as and for the purposes hereinbefore set forth.

2. In a ring spinning frame, the combination of the ring rail, the separator shaft, the separators mounted thereon and provided
