SPINNING FRAME.

Application fi led March 10, 192a. Serial No. 542,675.

' To all whom it may concern:

Be it known that I, ARTH R C. VARNUM, a citizen of the United States, residing at Southbridge, in the county of VVo-rcester and Commonwealth of Massachusetts, have invented new and useful Improvements in a Spinning Frame, of which the following, together with the accompanying drawings, is a specification. i

My invention relates particularly ,to cap spinning frames and has for its object to provide improvements in the construction and arrangement of the thread guiding means and associated .parts, whereby the spinning frame as a. whole'willbe rendered more effective in its operation.-

Among the advantageous results obtained by the use of my invention, are the substantial elimination of the collection of fly around the thread guides during the operation of the machines, and the possibility of turnin of the others while spinning, or of liftin all of the thread guides in unison when do ing. A still further advantage of my improved construction lies in thefact that the separator plates between adjacent caps and spindles are extended above the line of the thread guides so as to substantially eliminate the possibility of double spinning. in addition to performing their usual function, that is, the prevention of the yarn from adjacent caps from becoming entangled due to the ballooning action of the yarn. The above, and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying drawings in which,

Fig. 1 is a view in end elevation of a portion of a spinning frame embodying my invention.

Fig. 2 is a view in front elevation of the parts shown in Fig. 1. r

Fig. 3 is a plan view of the parts shown in Fig. 1.

Fig. 4 is a fragmentary view in side elevation showing one of my improved thread guides on an enlarged scale.

Like reference characters refer to like parts in the different figures.

Referring to Fig. 1, the roller beam of a spinning frame is indicated at 1, to which is secured a thread board 2. A lifter'bar 3 is secured to the front edge of the thread board 2 by hinges 4, as best shown in Fig.

each thread guide independently 3. A'plurality of hinge brackets 5' are fsecured to th front face of the bar 3, each bracket providing apair of ears 6 between which is pivotally mounted a thread guide. or pot-eye holder 7 by means of a pin 8. As best shown in Figs. 3 and 4, each holder 7 consists of a strip of metal bent back on itself where it enters between the ears 6, opposed portions ofrthe strip being curved outwardly as indicated at 9 to provide a seat for the reception of a pot-eye or guide 10 which is providedwith a top flange 11 supported by the portions 9. Each poteye 10 is preferably formed of porcelain, or other similar smooth and durable material, and is provided with acentral thread opening 12 and a slot 13 communicating therewith. The side portionsof the holder 7 extend outwardly beyond the pot-eye seat to provide flaring wing portions 14 for guiding the thread into the opening 12.

The pot-eye holder 7 normally occupies V the position shown in Figs. 1 and 2,'so that the pot-eyes 10 are positioned for) convenlently receivlng threads from the drawing rolls 15, only one pair of which is shown.

The thread opening 12 of each pot-eye 10 is thus held substantially in alinement with the vertical axis of a spindle or of a cap and spindle 16, a thread] 17 being shown in Fig. 1 as passing between the rolls 15 through a pot-eye to the spindle 16. With the above described 'arrangemetnt it is obvious that each holder 7 may be lifted about its pivot pin 8 into the position shown in dotted lines in Fig. 1 at any time during spinning, or all o of the holders 7 may be lifted in unison byturning the bar 3 on its hinges 4 into the position shown in dotted lines in Fig. 4

a when it is desired to doff the machine, as a whole. When an individual holder 7 is lifted, as shown in Fig. 1, it returnsto its original position as soon as it is released, whereas when all of the holders 7 are lifted by thebar 3, as shown in Fig. 4, the holders will fall back into the position shown and remain out of the way during the operation of dofling. V

A plurality of spaced separator plates 18 are arranged between adjacent caps and spindles 16, each plate 18 extendingfrom a point near the lower edge of a cap upwardly into the spaces between adjacent pot-eye holders 7. Each plate 18 is provided with a notch 19 for receiving the bar 3 and the Q v r 1,494,825

double the desired size as frequently occurs when the pot-eyes are mounted on a continuous board with nothing interposed between adjacent pot-eyes, as in previous constructions.

Tith my improved. arrange ment of separate pot-eye holders 7 it is possible to extend the'separator plates upwardly between adjacent holders as far as is From the foregoing, it is apparent that I have provided an improved arrangement of the parts of a cap spinning frame whereby it is possible to lift the thread guides, or pot-eyes, either separately or in unison, as desired, my improved construction being such that there are no flat surfaces adjacent to the thread guides for the collection of fly or lint. hfy construction further includes the use of separator plates between adjacent caps and) spindles which extend from a point near the lower edges of the caps upwardly above the pot-eye holders and thereby effectively prevent double spinning, as well as eliminating the bad efiects of the ballooning ofthe yarn.

IVhile I have shown my inventionas applied to a particular arrangement of parts, it is not so limited, but is susceptible of such modifications and changes as may come withinthe scope of the appended claims.

I claim,

1. In a spinnlng frame, the combination with a plurality of spaced caps and spindles and a plurality of thread guides cooperating therewith, of separator plates extending between said caps and spindles and projecting above the said thread guides.

2. In a spinning frame, the combination with a plurality of spaced capsand'spind les and a plurality of thread guides cooperating therewith, of separator plates disposed between said caps and spindles and extending from the lower portion of a cap to a point above a horizontal plane passing through said thread guides.

3. In a spinning frame, the combination with a plurality of spaced caps and spindles and a plurality of thread guides cooperating therewith, of separator plates dispose-d between said caps and spindles and adapted to prevent double spinning and the entanglement of adjacent threads due to the ballooning thereof.

4. In a spinning frame, the combination with a plurality of spaced caps and spindles and a plurality of thread guides cooperating therewith, of separator plates extending upwardly from between said caps and spindles and adapted to--' prevent a broken thread from one thread guide entering the next adjacent thread guide.
