SLEEVE-WHIRL SPINDLE FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 333,822, dated January 5,1886.

Application led April 21, 1884. Serial No. 128,744. (No model.)

To all whom, it may concern:

Beit known that I, EDWARD E. BRADLEY, of Stonington, county of New London, State of Connecticut, have invented an Improvement in Sleeve Whirl Spindles for Spinning- Frames, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The object of my invention is to obviate evils due to too tight banding or strain of the bands, and at the same time drive the bobbincarrying spindle frictionally or adhesively.

In my invention the spindle is divided or made in two parts,one part placed in abolstercase and having a sleeve-whirl attached to it, beingherein called the whirl l or driving7 spindle, while the other part, which receives the bobbin upon is called the bobbincarry ing7 or driven spindle, the latter having attached to it a supporting-foot,which is held frictionally or adhesively to apart of the sleevewhirl of the spindle, as will be described.

Figure l represents a spindle and its co-operating parts to be described, the former iu elevation and the latter in vertical section; Fig. 2, alike view of a modification, and Fig. 3 a section of Fig. 2 in the dotted line x x.

In the drawings, A represents a spindlerail, and B a bolster case and step of usual construction, it having a suitable bolster or bushing, C, which in practice will be grooved in any usual manner for the passage and circulation of oil. The rotatable whirl-spindle D, having its lower end entered loosely into the stationary bolster-case, has securely attachedto itthesleeve-whirlD,iianged,asusual, for the reception of the spindle-'driving band, and, as herein shown, the said sleeve-whirl is provided with a cap, E, having a lip or projection, 2, to support one end of a spring, s, the opposite end of the said spring resting against the spring-support g2, attached to and moving in unison with the driven spindle G, the latter having attached toit the supporting foot or portion g3.

In Fig. l the supporting-foot g3 and springsupport g2 are connected by a sleevelike portion, which is extended downward about the tubular body of the sleeve-whirl and between it and the cap E, the spring s placed inside the cap and resting on the lip g2 serving to hold the driven spindle G down with its supporting-foot g3 against a washer, m, on the sleeve-whirl, thus rotating the driven spindle G through the friction exerted by the spring s, the force of which may be varied and made more or less by adjusting the cap E, screwthreaded, as shown in Fig. 1, and engaging a threaded part of the projection h of the sleevewhirl. A small space, 3, in practice about one one-hundredth of an inch, is left between the sleeve-whirl and the supportingfoot g3,to permit the spindle G to adjust or center itself to its load, as is well understood, the supportingfoot g3 being held against the washer m by the stress of the spring s, as stated.

In the modification shown in Fig. 2 the cap E is attached to the upper end of the sleevewhirl, and the lip g2 for supporting one endof 70 the spring s is made as a collar screwed upon the driven spindle,a portion of which is passed into the cap E, the portion 2 of which acts against the opposite end of the said spring.

In both the spindles described the principle of operation is the same.

I am aware that a bobbiucarrying spindle has been driven from a sleeve-whirl or lower spindle by means of a projection on one entering a notch in the other, thus forming a positive driving means; but I am not aware that one part of a spindle has been made to drive the other part i'rictionally through the intervention of a spring, and especially a spring the force of which may be adjusted.

I have shown but do not herein broadly claim the downwardly extended sleeve attached to the bobbin-carrying or driven spindle G; neither do I claim its combination, broadly, with the sleeve of the whirl, as that forms the subject of claims in my application No. 128,745.

I claim- 1. The rotatable whirl-spindle D, the stationary bolsteccase provided with a chamber to receive the lower end of the whirl-spindle,the whirl attached to the said spindle,the cap provided with the iiange 2 and a washer, combined with the spring s and the bobbin-car rying spindle` provided with a supporting-foot, g3, and a lip, g2, the said spring acted upon or held between the said flange and lip holding IOO the foot y3 against the washer and permitting l force of the springend with a support for the ro the bobbin-carrying spindle to move or tip I said spindle D, substantially as described. laterally on or with relation to the Whirl- In testimony whereof I have signed my spindle, the combination being and operating name to this specification in the presence of substantially as described. two subscribing Witnesses.

2. The bobbin-carrying spindle provided EDWARD E. BRADLEY. with a foot and spring support and the spring, lVitnesses: combined with the whir1-spind1e D, provided Jos. F. JOSEPH,

With a Whirl and adjustable cap, to vary the WM. A. GILBERT.
