SEPARATOR MECHANISM FOR RING-SPINNING FRAMES.

SPECIFICATION forming part of Letters Patent No. 498,267, dated May 30, 1893.

Application filed February 10, 1893. Serial No. 461,729. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES L. I-IILDRETH, a-citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Separator Mechanisms for Ring-Spinning Frames, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to separator-mechanisms of the class in which the separators are applied to suitable supports that are carried by vertical rods, termed separator-rods, having communicated thereto a vertical reciprocating movement resembling that which is communicated to the lifting-rods which support the ring-rail with its rings.

More particularly, the invention relates to the means for imparting to the separator-rods and the parts which are supported thereby the vertical reciprocating movement aforesaid.

The main object of the invention is to provide a simple, inexpensive, and convenient arrangement and construction of parts for communicating movement to the separatorrods, the same including a convenient means of effecting the vertical shift or translation of the traverse of the separators which sometimes it is desired and necessary to make without altering the extent of such traverse;

The invention consists in a novel combination of parts, and in certain novel features of construction, all as hereinafter is fully described with reference to the accompanying drawings, and as is particularly pointed out and clearly defined in the claims at the close of this specification.

In the accompanying drawings, Figure 1 is a View in front elevation showing a portion of a ring-spinning frame with my invention applied thereto. Fig. 2 is a view in vertical section on the line 2-2 of Fig. 1. Figs. 3 and 4 are detail views, the former being partly in section, illustrating the details of my improved devices.

In Figs. 1 and 2, 1 is the roller-beam, 2 the thread-board hinged thereto as usual, 3 the finger-boards hinged as usual to the threadso board, 4 the yarn-guides secured to the finger-boards, 5 the yarns passing from the yarnguides 4 .to the bobbins 6, through the travelers 7 on the rings 8 supported by the ring-

rail

9, 10 the spindles on which the bobbins are mounted, 11 the spindle-rail, 12 the lower or guide-rail, 13 the lifting-rod for the ring-rail, 14 the shoe or foot at the lower end of the said rod, 16 the cross-shaft arm carrying the stud or pin 15, the latter either acting directly upon the said shoe or foot or being provided with the roller 151 which acts against the said shoe or foot and fits upon the stud or pin 15. i.

At 17 is shown the cross-slot in the free end of the said cross-shaft arm 16 in which the said stud or pin is adjustably mounted, and at 18 the cross-shaft on which the said arm is secured, the said cross-shaft turning in bearings in brackets 19 (only one of which brackets is shown) and being caused to rock by usual means for the purposeof moving the ring-rail up and down. I At 20 the separators are shown, and at 21 the rail on which the separators are mounted. All of the foregoing parts may be of any usual or preferred construction.

At 22 is shown one of the separator-rods by the upper ends of which the separator-rail 21 is supported, the said rod being held in upright position by guides 23. Provision for actuating the rod 22 from the cross-shaft arm 16 simultaneously with the actuation of the ring-rail from the said arm, and in .the same direction but through a traverse of less extent, is made as follows, reference being had to Figs. 3 and 4, also: Upon the separatorrod 22 is slipped the collar 24, the said collar being secured in place at an intermediate point in the length of the separator-rod by means of a clamping-screw 25 which is fitted to a threaded hole in the collar and takes bearing at its end against the shaft. The said collar isprovided with a laterally projecting pin 26 on to which is fitted the upper end of an arm or link 27, the said end of the arm having a hole through which the pin 26 passes, and the arm being held in place upon the pin 26 by a split-pin 28 which is passed through a hole in the end of the latter. The arm 27 hangs vertically, and the lower part thereof is bent forwardly so as to overhang the cross-shaft arm 16, on the upper surface of which rests its tapered lower end 29, the point of the said end entering a concavity 30 formed in the said arm 16 at a point between the axis on which the latter turns and the point at which movement is transmitted from arm 16 to the lifting-rod. The weight of the parts supported by the arm 27 holds its lower end in contact with the arm 16, so that the separator-rail and separators rise and fall in unison with the ring-rail and rings, and as the arm 16 moves up and down through the arc in which it vibrates the arm 27 swings freely on the pin 26 to permit the lower end thereof to move laterally and follow the curve of the are which passes through the point where the arm 27 rests on the arm 16. The lower end of the arm 27 has no positive connection with the cross-shaft arm 16, and hence the arm 27 does not act like a connecting rod to draw the separator-rod and parts carried thereby positively downward.

In consequence of the fact that the arm 27 rests on the cross-shaft arm 16 at a point between the axis of the latter and the point at which movement is transmitted from arm 16 to the lifting-rod it follows that, while the separator-1'ail and separators are caused to rise and fall simultaneously with the ring-rail and rings, they are movedthrough a traverse of less extent than the latter, as is necessary in order that the separators may be maintained at all times in proper position relative to the parts to which they are adjacent in the spinning-frame.

By varying the point at which the collar 24: is fixed by the screw 25 to the separator-rod 22, the height of the separator-rail and separators in the spinning frame may be varied as required, and, also, the traverse of the separators may be shifted or translated vertically without the extent of such traverse being changed.

I claim as my invention- 1. The combination with the separators, the separator-rail, the separator-rod, and the cross-shaft arm, of the depending arm pivotally connected at its upper end to the sepa rator-rod and resting at its lower end upon the cross-shaft arm, whereby the separatorrod and parts carried thereby are sustained vertically and moved up and down with the cross-shaft arm, substantially as described.

2. The combination with the separators, the separator-rail, the separator-rod, and the cross-shaft arm, of the collar mounted on said rod, means for securing the said collar in desired position on the said rod, and the depending arm pivoted at its upper end to the collar and resting at its lower end upon the cross-shaft arm, whereby the separator-rod and parts carried thereby are sustained vertically and moved up and down with the cross-shaft arm, substantially as described.

3. The combination with the ring-rail, the

lifting-rod, the cross'shaft arm acting to move the lifting'rod, the separators, the separatorrail, and the separator-rod, of the depending arm pivotally connected at its upper end to the separator-rod and resting at its lower end upon the cross'shaft arm at a point between the axis on which the said arm turns and the point at which movement is communicated to the lifting-rod, substantially as described.

4. The combination with the ring-rail, the lifting-rod, the cross-shaft arm acting to move the lifting-rod, the separators, the separatorrail, and the separator rod, of the collar mounted on said rod, means for securing the said collar in desired position on the said rod, and the depending arm pivoted at its upper end to the collar and resting at its lower end upon the cross-shaft arm at a point between the axis on which the said arm turns and the point at which movement is communicated to the lifting-rod, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
