OF BRIDG-EPORT, CONNECTICUT, A COB- REEL.

Application led December 7, 1925. Serial No. 73,688.

This invention relates to reels for artificial silk or the like, and has for its main object and feature the production of a reel of such character that a Washing or dyeing operation may readily be carried o'nwth respect tothe l material Wound thereon.

In the accompanying dra-Wingsthe invention is disclosed'in a concrete' and preferred' lform. in which :v

Fig. 1 nis a longitudinall sectional view of a device embodying one form of the invend tion.

Fig. 2 is an end elevation looking in the direction of'arrow 2 ofl Fig. 1. j

Fig. 3 is a-transverse sectional view on the plane of line 3--3 of Fig. 1. Fig. 4 is a view of the carrier looking' in the direction of arrovvr 4 of Fig .2.

The device of this invention is particularly though not exclusively designed to be used in connection with a machine of the character disclosed in application Ser. No. 75,093 iled December 12, 1925, now Patent 1,678,053,

July 24, 1928, in which the artificial silk is Wound upon a spool and the washing or dyeing fluid is drawn through the material and spool to edect the washing or dyeing operation. v v

The reel consists of a carrier 1 and a spool 2 detachably mounted thereon. The carrier is provided with a circularly extending abutment surface 1 from which rise, substantially at right angles thereto, a plurality of spaced projections 6 having slots 7 in their outer surface that extend substantially par.

allel to the abutment surface. Covering said projections in the plane of the slots is an elastic medium here taking the form of an elastic band 8 that passes around all of the projections. The spool consists of va hollow shell, preferabl o sheet material, having perforations a lew of which are shown at 3, and here own as being provided with strengthening beads 4 which constitutes a circu arly extending abutment portion substantially at right angles to' the axis of the spool and arallel to abutment surface 1. The spool a so carries a plurality of inwardly projecting AVand spaced detents 5 in the plane of the slots.l It Willnow be understood that the operator, by inserting his hand into the interior ofthe shell, may slip the shell on the carrier andv bring abutment portion 4 against abutment surface 1. Then, while retaining the abutment members in engagement, a slight twist will bring detente 5 into compressing the latter into slots 7, and that this can be done Without in any way damaging the delicate threads Wound on the outside of the' spool. The reverse 'operation will of course release the parts.v The thread is Wound on the spool in the spinning machine and it is essential to the Washing or dyeing process that the winding process be carried on properly, that is to say; openings 3 must be covered and not exposed if the dye or other fluid is to be drawn or freed through the threads. It is therefore essential that the spool run true in the winding machine, and as the spool runs as high as four hundred revolutions a minute it may easily free itself from or become displaced with respect to the carrier. The abutment members and the parallel arrangement of the .slot and de tents will prevent any loosening of the spool While rotating because, as shown by the drawing, the locking means do not work on the principle of a bayonet joint, that is to say: there is no inclined slot-and-pin connection. The result is that the spool runs true, but nevertheless it ma be detached and attached uickly when s ifting it from a carrier in t e winding machine to a carrier in the dyeing or Washing machine.

I claim:

The combination with a carrier having a circularly extending abutment surface, of a plurality of spaced projections on said carrier rising substantially at right angles from the abutment surface, each projection provided with a slot in its outer surface that extends substantially parallel with said abutment surface, an elastic covering, for each projection, in the plane of its slot, a spool to surround the 95 projections and to be thereby detachahly se cured to the carrier, a circularly extending abutment portion, on said spool, substantially at right angles to the axis of the spool and parallel to the abutment surface to engage 10o the latter, and a plurality of inwardly rojecting and s aced detents on said spoo in the plane oft e slots to enga e and compress or to disengage and release t e elastic coverings upon producing a relative turning movel105 ment between the spool and carrier While the abutment surface and abutment portion are in engagement. v

igned at Bridgeport in the county of Fairfield and State of Connecticut this 27 11o day of November 1925.
