Patented Apr. 24, 1934 SPOOL HOLDER Richard J. Gollong, Johnson City, Tenn., assignor to American Glanzstofi Corporation, New York, N. Y., a corporation of Delaware Application April 1, 1932, Serial No. 602,583

6 Claims.

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 extruded into a suitable coagulating bath in the form of thread and collected on spools which may be of the perforated or foraminated type. These 9 spools are 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 thread guide. Since the thread is spun into a coagulating bath of acid reaction hereto- 5 fore great difiiculty has been encountered by the eating away of the spool holder by the liquid of the bath. Many types of spool holders are known to the trade which have been designed in an effort to overcome this difficulty. The use of 26 aluminum spool holders has been tried but they are unsatisfactory since the aluminum dissolved by the liquids of the bath will appear as aluminum spots when the thread or yarn is dyed. Spools made of other metals have been tried but they are either too expensive to be used on a commercial scale or are soon rendered useless by the action of the acid of the coagulating bath thereon.

It is therefore an object of my present invention to provide a new type of spool holder which will correct the above mentioned difficulties.

Another object of my invention is to provide a suitable means to secure the spool holder to the shaft whereby when the parts become eaten away by the liquids of the coagulating bath, or otherwise damaged, they may readily be replaced.

A further object of my present invention is to provide a spool holder having means associated therewith which will hold the spool mounted thereon in position, and at the same time be of such a construction and be made of such material that the holder will not be readily damaged by Figure 4 is a view corresponding to Figure 1,

but showing a modification thereof;

Figure 5 is a top plan view of the parts shown in Figure 4; and

Figure 6 is a detailed view of one of the holding blocks to be used with the spool holder shown in Figure 4.

Referring now to the drawings, and more particularly to Figures 1-3, I have shown a preferred embodiment of my present invention. My new holder is made of hard rubber or other acid resistant material, and consists of a .base 10, the surface 11 of which is tapered, merging into a cylindrical portion 12 provided with a centrally formed closed bore 13, adapted to receive the end of the blade 14 of a spindle (not shown). The bore is located along the horizontal or median axis of the holder to avoid any possibility of having the spool run untrue while the thread is being wound thereon.

I have provided a suitable means for holding the spool holder in place on the spool holder shaft, and which may be readily removed when rendered unfit for use either by the action of the acid of the coagulating liquid or for any other reason. This securing means consists of a ring or collar 15 made preferably of aluminum and which is provided with a threaded opening 16 adapted to receive the set screw 17. This collar or ring fits snugly around the cylindrical portion 12 of the holder and the set screw engages the blade 14 through the opening 18 formed in the cylindrical portion 12.

Formed integrally with the base is an upstanding hollow cylindrical member 19. The circumference of this portion is less than that of the circumference of the base thus providing a suitable seat 20 for the spool 21. The cylindrical member is also provided with a plurality of cutaway portions 22, preferably three in number defining three shoulders. Each of these shoulders is provided with rectangular slots 23 located adjacent the upper edge thereof.

Referring now more particularly to Figure 3, I have shown in detail my novel form of holding means. The holding means consists of an insert or spider 24 having three arms or leg portions 25. 'Each arm or leg is constructed at its outer end of hard rubber, the remainder thereof being' of resilient or soft rubber. A shoulder 26 is also provided adjacent the end of each arm which defines the limit of extension of the end thereof through oneof the slots 23. As may readily be seen from an inspection of Figure 3 the arms or leg portions of the insert or spider are made eccentric with respect to each other so that, when the spool is being placed in theholder, the tips of the arms or legs may be pushed inwardly bending the arms or legs and thus causing sufiicient pressure to hold the spool firmly in place on the holder.

In Figures 4, 5 and 6, I have shown a modified form of my invention. The base 10 is provided with a tapered surface 11' merging into a cylindrical portion 12' provided with a centrally formed bore 13' adapted to receive the end of the blade 14'. The bore is located centrally along the horizontal or median axis of the holder to avoid any possibility of the spools running untrue while the threads are being wound thereon.

A collar or ring 15 is used to secure the spool holder to the shaft and is of the same construction as that described in the description of the modification shown in Figures 1, 2, and 3.

The means provided to clamp the spool to the holder consists, in this instance, of a plurality of composite blocks 2'7. Each block is substantially rectangular in form having its outer surface made of an abrasion resisting soft rubber compound while the remainder thereof is of hard rubber. These blocks fit in the rectangular slots 23' provided therefor in the substantially cylindrical body member 19'. Each block is also provided with a shoulder 28 to limit the outward movement thereof through the slots. The inner edges of the blocks bear against a resilient hosing or tube 29.

In operation, the clamping members are in the position shown in Figure 4 and the spool is forced against the tapered surfaces 30 'of the blocks forcing them inwardly against the resilient hosing or tube which in turn resiliently holds the blocks against the inner wall of the spool with suflicient pressure to clamp the spool and holder together.

From the above description it will be appreciated that I have provided a new type of spool holder made of a hard rubber acid resisting compound which will alleviate the manifest defects existing in the present type of aluminum or other metallic holders. Moreover, I have constructed my holder that should any of the parts become damaged or otherwise rendered inoperative, they may readily be replaced without the necessity of discarding the entire assembly, thus decreasing to a considerable extent replacement costs.

While I have disclosed and described the preferred forms of my invention, it is obvious that many of the details of the construction thereof .may be varied and I desire it to be understood that my invention is not to be limited except by the scope of the appended claims.

What I claim as new is:

l. A spool holder comprising a base provided with a downwardly extending hollow member adapted to receive a spindle blade, means to hold a spool on said base comprising an upstanding hollow member formed integrally therewith provided with a plurality of spaced openings, and a unitary multi-armed insert located in said upstanding member, the arms thereof extending into said openings and bearing against said spool, said arms being eccentrically positioned with relation to each other, and means to secure said holder to said blade.

2. A spool holder comprising a base provided with a downwardly extending hollow member adapted to receive a spindle blade, means to hold a spool on said base comprising an upstanding hollow member provided with a plurality of spaced openings, a unitary multi-armed insert located in said upstanding member, the arms thereof extending into said openings and frictionally engaging said spools, said arms being eccentrically positioned with relation to each other and means to secure said holder to said blade.

3. A spool holder comprising a base provided with spindle blade engaging means, means to hold a spool on said base comprising an upstanding hollow member provided with a plurality of spaced openings, a unitary multi-armed resilient insert, the arms thereof extending through said openings and frictionally engaging said spool, said arms being eccentrically positioned with relation to each other.
