BEEL DR SWIFT USE'IH THE VJINDEN TEXTILE YARNS.

Application filed December 24, 1925, Serial No. 77,534=,and in Great Britain October 1, 1985.

This invention relates to reels or swifts on" which yarns are to be wound or on which they are to be placedin the hank form for rewinding therefrom, and is particularly ap- I pllcable to swlft-s whereon artificial silk,

yarns are to be wound from the package 111 which the said yarns have been spun, for instance, a cake as it comes from the spinning box in one of the viscose processes. The artificial silk at that stage is very liable to damage, being fragile and having little cohesion, and such damage does take place in removing the wound'hank from the swift for the subsequent treatment necessary.

My invention has for object a means for ensuring that a hunk may be safely removed from a swift without danger of rupture of any of the yarn coils, and in carrying the said invention into effect fo in the swift with arms which are all slidable radially, with means for sliding such arms simultaneously. A hank can thus after winding be left absolutely loose on the yarn bearing nuns, for easy removal. i

Although the invention is exceedingly useful for the purpose just stated, it can be equally well applied, as will be understood, to reels on which hanks of any fragile yarn have to be placed for winding off, as such hanks can be safely and rapidly put in position on the reels by sliding the reel arms inwardly, and then outwardly after the hank is in position to tighten the latter sufiiciently. i

The invention, in a very convenient manner of carrying it into effect, in a swift for the winding into hanks of artificial yarns, will now be described with reference to the accompanying drawings, in which Figure 1 is a side elevation of a swift showing the arms in two positions; and Figure 2 is a horizontal cross section taken centrally of Figure 1.

Referring to the figures, 3 is a squared driving shaft having the circular necks f two discs 5 being secured on this squared shaft by the grub screws 6. These discs will be referred to later. The hub 7 of the swift is of wood, this hub having a central b re. On each end of this hub are screwed the hub flanges 8 each flange being of sheet metal and having their peripheral edges turned over as shown in the figures, the turned over edges being slotted as at 9 for the passage of a swift arm 10 and to main tain the same vagainst angular movement in relation to the hub. Each hub flange 8 is radially, slotted as at 11 and the inner end of each arm 10 of the swift is returned at 12-see Figure 2and enters a slot 11 being slidably securedtherein by the distance col lar18, and the nut lei. Guides. 15 are punched from the metal of each hub flange on either side of 21111 10, these punched out guides 15 being perpendicular to the face of the flange Holes 16 may be punched iii-each hub fiaiige 8 for lightness.

Upon each returned end 12 of an arm 10, and held in place thereon by the distance piece or collar 13 and the nut 1th, is pivoted the end of a link 17 the other end of which is pivoted upon a headed screw 18 in the ad jacent disc 5. Normally, when the arms 10 are fully extended outwardly, a slot 11., an arm 10, and a link 1? lie on the same radius line of a hub flange 8.

To one of the discs 5 is secured as shown in the figures an arm 19, cranked so that its free end lies closely adjacent to the hub flange on that side, and having fitted on the said free end the handle 20. A pin or'the like 21 on the cranked arm fits, by the re silienoy of the metal of such arm 19, within either of two holes 22 and 23 in the adjacent hub flange. More than two such holes may be provided. c

As thus described and as shown in full lines in Figure 1 and in section in Figure 2, the arms are fully extended and the swift is in the Winding position. To remove a wound hank, handle 20 is pulled away from the hub flange 8, the wooden hub 7 is firmly grasped and the disc 5 to which the handle is attached is given angular motion, the disc on the other side receiving the same motion. The swift arms 10 are thus drawn inwardly, and the links 17 and swift arms 10 assume the position shownin dotted lines in Figure position of the arms 10, the yarns are shown in dotted lines.

For clearness 01 description I have referred to the arms 10 on each side of the swift as being separate. Two opposing arms hm'veVer are preferably formed in one, the central portion being cased With ehonite or like materiel which will Withstand the action of the corrosive acids in artificial silk yarns as they come from the spinning process.

I claim its a means the winding fragile yarns into or ozn hanl: form, a squared driving shaft, discs fixed upon the said shaft, 2 central tubular Wooden hub mounted upon the shaft between the discs and having end flanges concentric with the s id discs, the shaft being capable of angular lnoveinent relatively to the hub and its i'lang'es when the said hub is held to prevent its movement, a spring handle With pin mounted on one of the discs and adapted to engage in holes formed on radii'of an adjacent hub flange, arms radial to the hub and hearing yarn carrying surfaces at their outer ends the inner ends being returned and such returned ends slidebly engaging in radial slots in the hub flanges, means for slidably securing the returned ends Within such radiel slots, supports inthe flanges to preserve the radial relation of the arms thereto, and a pivoted link between each such arm and a point on 1-: radius of an adjacent driving shaft disc.

.In testimonywhereof I have hereunto set my hand, 7
