This invention relates to improvements in spools for use with mule spinning, carding and like machines and has particular reference to the method of making the same. t

Spools of the character embodying the invention are adapted for use in carrying a plurality of wool strands or the like which are initially wound on the spool and which are thereafter withdrawn therefrom during spinning, carding or like operations. In performing such operations the spools are manually placed on and removed from the machines and must be manually placed in and trucked from one machine to another. spools are relatively large and, when filled with wool strands, are quite heavy and bulky to handle and thereby receive considerable abuse during the handling thereof either from accidental dropping, from bumping the heads of the spools against the frames of the machines during their removal or replacement or from throwing the spools into the trucks by means of which they are conveyed from one machine to another.- One of the primary difculties has been that the ends of the barrels soon became displaced or bent with the result that the heads could not be supported in proper angular relation with the barrel or wererendered too loose for continued There are various types of spools on the market, all of which have attempted to overcome the above difliculties. Some of these spools are provided with a wooden barrel having the heads attached tothe opposed ends thereof by centrally disposed clamp bolts which enabled periodic tightening of the heads. It has been found that during use and due to the abuse which such `devices encountered, the ends of the Wooden barrels would either split or the material thereof became displaced to such an extent that the heads could norlonger be properly angularly disposed relative to the barrel or be suiciently tightened.

Another difficulty has been that such barrels become splintered to such an extent that individuals handling the spools often received severe injuries from slivers and further difficulty was encountered in being unable to freely draw the woolen strands from the barrels.

To overcome this difficulty other spools appeared on the market having the barrel portion thereof formed of tubing to which the heads were attached by centrally disposed relatively long interconnected sections of coil ice in connection with the accompanying drawings wherein FIG. 1 is a side elevational view of a spool embodying the invention;

FIG. 2 is an end view of the spool;

FIG. 3 is an enlarged fragmentary sectional view taken as on line 3 3 of FIG. l and looking in the direction indicated by the arrows;

FIG. 4 is a fragmentary sectional view of one end portion of the device embodying the invention;

FIG. 5 is an enlarged fragmentary sectional view taken as on line 5-5 of FIG. 3 and looking in the direction indicated by the arrows; and

FIG. 6 is an enlarged fragmentary sectional view of a modified form of the invention.

Referring to the drawings wherein like characters of reference designate like parts throughout the various views, the device embodying the invention comprises a Such U barrel 7 formed of hard plastic tubular material or metal of the length and diameter desired of the main body portion of the barrel. Press fitted internally of the opposed ends of the barrel 7 is a cylinder shaped member Shaving an inner closed end wall 9 and a circumferential flange 10 spaced inwardly of the opposed end of said cylinder member. The closed end wall 9 may be formed integrally with the cylinder member 8 or may be attached thereto by welding or the like as indicated at 11 and is provided with a circumferential peripheral stantial, reinforced inner wall for `said barrel 7 to resist spring tensioning means which was designed to relieve the head and barrel connections from shock and'strain as the result of the abuse they receive during the use of the spool. This type of spool did not solve the problem for the ends of the barrel soon became bent and displaced to such an extent that the heads not only loosened but tilted to an undesirable angle and rendered the spools impractical for use.

It, therefore, is one of the principal objects of the present invention to provide a spool which will overcome all of the above difficulties and which will be durable, resistant to displacement, impact, chipping, bending or splintering and having its head portions attached to the spools in such manner as to prevent the heads from becoming loose or angularly displaced during the use thereof, which will not require periodic tightening and which may be fabricated in a simple and inexpensive manner. l

Other objects 'and advantages of the invention will become apparent from the following .description taken l the parts in assembled relation with each other.

the said endsjfrom being dented or collapsed-inwardly. The flange 10 may be formed lintegrally with the cylinder member 8 or may be secured thereto by welding in a manner similar vto the closed end wall 9.

- The flange 10 is rprovided with a plurality of spacedbeveled openings 12 throughout a circumferential path as shown best in FIGS. 2- and 3 and is adapted to lie within a shouldered recess 13 formed in the inner side of the head 14 'as shown best in FIG. 3. The adjacent end of said cylinder member 8 is adapted to extend outwardly of the flange 10 as shown at 15 and to extend inwardly of an opening 16 formed centrally of the head 14.

Overlying the outer surface of the head 14 is a disk 17 preferably formed of metal having a pivot pin 18 formed integrally therewith, with said flange and pin being preferably formedV of steel or other similar hard, wear-resisting metal. Fitted over the pin 18 is a spacer washer or the like 19 which is secured to the outer surface of the disk 17 by Welding or the like. The said disk k17 is provided with spaced openings similar to and aligned with the openings'in the ange 10 and is adapted to receive rivets or the like 20 which extend through similarly formed aligned spaced openings in the head 14 to secure The inner ends of the rivets 20 are ared outwardly to iit vinternally of the tapered openings 12 in the flange lll with the said ends in substantially flush relation with the inner surface of said flange and are provided with outer enlarged heads overlying the disk 17.

The washerlike' member 19 has a shouldered central surface 21 which causes the washerlike members 19 to be of a thickness greater than the thickness ofthe outer heads of the rivets so as to permit free rotation of the spool in its conventional support on spinning or carding mai chines or the like without hindrance from rotation by y being rigidly attached to the respective ends of the barrel.

said outer enlarged heads of the rivets. The head portions of the spool and the associated parts thereof, including the cylindermember 8 and inner wall 9, while 7 by frictionally pressing said cylinder members 8 and end walls 9 into said ends and to a degree wherein the adjacent outer edge surfaces of the barrel 7 engage with the ilanges 1t) to provide a relatively intimate relation therewith to prevent the wool strands or the like which are wound on said spool from becoming wedged inwardly between said ends of the barrel and the ilanges 10 with the result that they cannot be freely drawn from said barrel.

While the head assemblies are provided with the cylinder members 8 and end walls 9 which are relatively long and press tted into the adjacent ends of the barrel 7, they are inwardly biased relative to each other by means of a rod 22 centrally disposed with respect to the barrel 7 and which extends through central openings 23 formed in said end walls to a point spaced inwardly relative to. the inner surfaces of the disks 17. The opposed endsv of said rod 22 are provided with threaded sections 24 adapted to each receive a threaded nut 25. Inwardly between the inner surfaces of the end walls` 9 and the inner Vsurfaces 0f the nuts 25 and in surrounding relation with the adja-V cent ends of the rod 22 there are provided coil springs 26. The tension of said springs is controlled by threading the nuts inwardly ot the respective threaded ends of the rods so as to set up a desired biasing eiect upon the respective heads of the device. This is to overcome the tendency of said heads working loose and requiring retightening during the use of the spool and is further. to resist any tendency of the heads being displaced outwardly of.l the respective ends of the barrel 7 while yetl permitting the said heads to yield in response to impact.

To insure that the nuts 25 do not loosen after once being adjusted to introduce the desired 'tension'to the. springs 26, the opposed ends 27 of the rod 22. are preferably flared over. While vthe heads 14. and the associatedv parts thereof are vdesigned to greatlyresistfimpact. the cylindermemb'ers 8 serve as inner reinforcing means for the respective ends of the barrel 7 while the coil springs 26 serve to permit a limited yieldingy action thereof in response to impact. and further prevent the heads from becoming loose during the use of the spool.

In FIG. 6 there is shown a slight. modilication wherein the ends of the barrel 7 are provided with sleeves 28v preferably formed of steel or otherrigid metal and ofa diameter such that they are intimately. press litted` internally of the respective ends of the barrel 7. The sleeves 28 are of a considerable length so asto provide adequate protection against the end areas of the barrel from being bent or otherwise dellected inwardly .and the outer ends thereof are positioned in iiush relation with the adjacent ends of the barrel to further protect said ends in response to any tilting movement of theheads. In this instance the cylinder members 8 arev formed so as to havey slight inward taper with respect to the inner surfaces of the sleeves 2 8y so as to provide a tapered clearance 29 of approximately no greater than 5 between said cyli'uder'mernbers 8 and the sleeves 28 adjacent the inner end thereof but theropposite or outer portions of said members 8' are so controlled dimensionallyV so as to havea relatively close lit within the outer ends of said sleeves 28.

The inner ends of the tapered cylinder members 8' are cach provided with a solidwall 9 in` a manner similar to the construction illustrated inFIG. 3A with Vthe exception that the said end` walls 9f arel ofv a diameter substantially equal to the inner diameter of the, cylinder members 8. The said cylinder members` 8', on the opposite ends thereof are provided with a. protruded end 15 and with a flange 10' similar to the construction of.. FIG.

3. The remaining construction of the heads are similarl to the construction shown in FIG. 3 and functions in a similar manner.

The cylinder members are formed relatively long so as to provide long inner bearing surfaces with the sleeves 2S when and if the heads are tilted in response to impact and the extent of yielding action of the coil springs are controlled in accordance with the length of said cylinder members to insure that they cannot be displaced outwardly of theends of said sleeves 28 during the use of the spool.

However, in this instance the tapered cylinder members 8' and the associated tie rods and coil springs permit a more free tilting movement of the associated heads in response to impact as well as preventing the heads Ifrom becoming loose and requiring retightening during the use ofthe spool. In this instance, while the heads and associated flanges 10' are permitted to more freely tilt in respouse to impact either from 4an outwardly or inwardly directed force, the sleeves 28 function to prevent the said ends of the barrel 7 from splitting as has been usual with the prior art spools of this nature and the Sleeves 28 further function to resist inward bending or compression of said end portions of the barrel in a manner similar tothe sleeves -8 shown in FIG. 3.

Itis to be understood that heads similar to the heads 14, disks similar to the disks 17 and spacer washers similarto the spacer washers 19 are employed with the present construction with the flanges -ltl'flying within recessed areas in the heads and with. the various parts being secured together by rivets or the like in a manner similar to the construction of-FIG. 3.

It is pointed'out that the barrels 7 or 7' may be formed of suitable plastic materials or metals as desired, all of which are resistant to cracking or splintering.

From the foregoing description it will be seen that simple, eicient and economical means and method have been provided for accomplishing all the objects and advant'ag'esof the invention.- Nevertheless, it should be ap parent that many changes in the details of construction, arrangement of parts and steps ofv the method may be made without departing from the spirit of the invention as expressed in the accompanying claims.
