. 2-Claims. (Cl. 242-465) My present invention relates to improvements in spool holders and more particularly to those types of holders adapted primarily for use in the manufacture of artificial silk.

In the manufacture of artificial silk and the like a suitable cellulosic solution is spun into a coagulatingmedium and then collected on spools. Each spool is mounted on a spool holder secured to a rotatable shaft, and the thread is laid thereon by leading the same over a reciprocating or oscillating guide. Since the thread is usually spun into a coagulating bath of acid reaction, the spool holders now in use are readily attacked by the liquid of said bath resulting in the necessity of a. frequent replacement of the spool holders. Many types of spool holders are known to the trade which have been designed to overcome this difficulty. The use of aluminum spool holders has been proven to be unsatisfactory since the aluminum is dissolved by the acid of the coagulating bath and causes the formation of aluminum spots on the yarn when dyed. The use of other metals has been suggested but these are open to the same objections or are impracticable to use on a commercial scale.

It is therefore an object of my present invention to provide a new type of spool holder which will obviate the abovedificulties.

It is another object of my invention to provide suitable means for clamping the spool to the spool holder and at thesame. time be of such a construction that the same may be readily replaced when worn or otherwise rendered unfit for further service.

These and other objects of my present invention will become more apparent from a study of the following description and by reference to the accompanying drawing in which:

Figure 1 is a section View of my" new spool holder on the line 1--1 of Figure 2 showing the same secured to the spool shaft;

Figure 2 is a top-plan view thereof; and

Figure 3 is a detailed view of the spool holding means.

Referring now more particularly to the drawing, I have disclosed thereon a preferred form of my invention. The base 10, made of hard rubber or other acid resistant material, is provided with a centrally located bore 11 adapted to receive the blade 12 of the spindle (not shown). This blade is threaded on its outer end and the spool holder is secured theretoby any conven ient locking means as by nut 13, and is provided with a shoulder 12 against which the base is held by the said nut. It is imperative to insure a perfect rotation of the spool during the spinning operation that the bore be located centrally of the base. l

Formed integrally with the base is' an upwardly extending hollow substantially cylindrical body member 14, the circumference of which is less than that V:ibf .the base thus providing a suitable seat 15 for, the end of the spool 16. A plurality of rectangular slots 17, preferably three in number, are formed in the wall of the ,hollow cylino5 drical member adjacent the outer' end thereof and are adapted to receive the spool locking means. A

The locking] means, shown in detail in Figure 3, each consists of a substantially rectangular 7o member 18 cut away at19 to form a shoulder 20 to limit the movement of same locking means in the slot provided therefor in the hollow cylindrical member 14. The outer end 21 of the locking member is wing shaped and the lip of veach wing is formed of stiff rubber. Since the inner end of Aeach locking member is larger thanv the slot in the cylindrical member within which it fits, I have provided a slot or cut-out portion 22 so that the furcations thus produced may be bent toward so each other suflicientlyvto permit insertion thereof in the slot in the cylindrical member.

In operation each of the slots in the cylindrical member is provided with one of these locking or holding members. The spool is then forced over the latter flattening the wing portions as indicated in dotted lines in Figure 2. 'Ihis causes the holding means to be pressed against the inner walls of the spool with sufficient force to hold the said spool securely on the spool holder. v

From the above description it will readily be appreciated that I have provided a novel type of spool holder the construction of which-is such as to render the same resistant against acids contained in the "spinning or coagulating bath. Moreover the device is constructed of few parts which are of such acharacter that should any one of them become damaged it may readily be replaced without necessitating thediscarding of the entire assembly.

Although I have described in detail'the preferred form of my invention, it is obvious that many modifications in the construction thereof may be made without departing from the spirit of my invention .or the scope of the appended claims. 05

What I claim as new is:

1. In a spool holder comprising an opening formed therein adapted to receive a spindle blade; means to hold a spool thereon comprising a hollow member extending upwardly from said' base 110 upwardly from said base and having a plurality of spaced openings formed therein, holding means having wing shaped outer ends secured in said openings adapted to bear resiliently against said spool, the inner ends thereof being biiurcated and shouldered to limit the outward movement of said members in said openings.
