MABIOCAMAGNL OF PATERSON, NEW' JERSEY.

Y SHUTTLE.

'. Application filed April a.

.lle it known that I, MARIO CAMAGNI, a. citizen of thelnited States, residing at Paterson.l ill the county of Passaic and State of'e/w' Jersey, ha ve. invented Certain new and useful In'lprovelnents in Shuttles,v ot which the following` is a specification.

'leans heretofore .proposed for securing the filling package on the s|i indlc of a shuttle` have been of such character that a coptulle, forming; the eoreof the package, would he usable. lult. a veryv few times` due 'to its bore-being` so' ahraded or wolll by th!- Securing means that the latters `grip thereon would cease to remain effectual to prevent slippage of the lilling package more-or less oil' the spindle. ill the violent hack and `forth nimenlents ol" the shuttle.

The object of this invention is to provide a spindle-` device .for shuttles wherein this object-ion will be overcome. vM v invention makes it possible. not only to use a. cop. tnhe until it becomes* useless .from other causes versc sectional than that attributable tonny wear which the improvement may engender,V but to use eoplallles ral-ying widely in size on the same spindle. l

1n the aceolnpanyin,"` drawing'` Figure 1 is a view of a shuttle provided with my improved spindle, the shuttle and the coptnbe on the spindle appearing,r in section and the spindle heiligr ill `its elevated position; Fig. L' is a plan view, the spindle being de e e. pressed auth l* lgs. 3 and 4 are a longltudlnal sectional view of the spindle and a. transview on the. Aline :L1- 17 in Fig. 3. Y

ln the shuttle a and `fulcrurned on the pin is the spindle c.

d is the eopltlzbe, in theprescnt-V ease .formed o'l paper and tapering, accordingr to custom. j 5

The'spindle isthl'eaded, as at e, throughout approxilru-itely its whole length. and preferably. in its upper side it has a longitudinal gioove f. .j

Screwed onto the spindle is theAcdp-grip member g, which is'in the form of a. sleeve of approximately the same dia meter throughA out and internally threaded to engage. the threadingr of the spindle. This oop-grip member is in the illustrated adaptation provided externally with Serrations i, and these are preferably in the form of threading. At ono .end the `eop-irip member pag a notch z', i

-is .a piece of spring wire 'bowed 'or arched slightly, arch' upstandingin the groove, and ha'vlng elle end la projecting out of the groove, being bentolf more or less at right angles, as best. shown in'Fig. 3, and its other end l rebent upon itself. '.llie key eXte dS;`

through the bore ol the sleevev g re' tained therein by thc best portion Ic and.' Z5

thereof. Upon sliding the key inthe groove toward `the free end of the spindld-"its end /rf may he engaged in the notelr'z' of the sleeve, te prevent the latte-r ,tlllning,fthe

key beingr heid against displacementtoward the butt of the spindle when thuslen.- gagged with the sleeve by rictional Contact of its bowed slee-re; v

` It being remarked that the 'bores-ofecp` tubes are tapered, it will-be apparent,.jin

portion with the bore of the.

view ofthe foregoing. that cop-tubes var-yf` ing; widely -in diameter may be eiectnally secured on the improved spindle, `biyingl lil-st adjusted the congriporf'sleeve. longitudinally of the spindle. so that when' the tube telly llome7 on the spindle the copgrip or sieevewill come :ltd point where il; will gri p the bor-e 'of' the cop-tnbe:'. 1he afdjust-ment of the sleeve olfcopgrip isiellectf ed h v forcingY the keylongitudinally 'toward the butt 'of the spindle until it clears the notch in the. sleeve, then turning thc'sleeve'. one way or the other llntll lthas been advanced to the desiredf position on the spin-v dle, and finally employing thel key torelock the sleeve against rotation. ily forming the serratiolls on the sleeve :is srrew-threading. when the tube is placed on the spindle and turned with some pressure toward the batt of the spindle the threadin g' ot the sleeve terms corresponding threading in the bore of the cop-tube; which thus becomes el'ectnally held to the spindle from longitudinal displacement` l' the. interior of a cop-tube becomes vorn where engaged by the cop-glip,i s onl necessary to adjust the latter fartlir toward the free end of the spindle, so that a fresh part of the bore of the cop-tube may be engaged thereby.

Haring thus fully described my invention1 what l @Lim as new and desile to secure by Lellerg Patient is:n

1 ln combination. a spindle struct-ure for shuttles ine-hiding a spindle proper and a cop-grip Ashorter than the spindle proper 'and adjustable longitudinallyY on and betwee'n the cn'dS of the latter, the spindle structure having' approximately the same general diameter in any transverse section the cop-grip.

Y2. In combination, a spindlefstructure for' shuttles includinga spindle proper`- and a cop-fgripsleeve shorter than the spindle proper and adjustable longitudinally Von 'and between the ends of the latter1 the spinl die structure havingv approxirn'ately the same generl diameter' in-any transverse sec.- tio'n thereof between the ends of the sleeve,

-whereby a cop or copo .tube having a conical bore may be slipped over and entirely house the-sleeve'.

1 '3Q In combination, a threaded -shuttle l spindle member, a cop-grip member screwed thereon, and adjustable by rotation thereon longitudinally thereof", and a key disengageably locking said members together against lrotation of the cop-grip .member on the spindleqnember.

4." In combination, a spindle member, a sleeve member screwed thereon and ad]ust Avable by rotation'A thereon longitudinally thereof, and a spring-extending between the sleeve anclspindle members and against each of them.

5. A shuttle'spindle device including a spindle, a cop grip member rotative on substantially the longitudinal '.xxisof the spindie. and7 having' screw connection therewith, and means to secure the grip member against rotation in various positions to which it is advanced .by screwing relatively to said spindle.l

In testiniony whereof I allix my signature.
