SPOOL.

Application filed' February 24, 1927. Serial No. 170,577.

This invention relates in general to spools and particularly to spools adapted for use in the steaming and soaking of fabric in the course of manufacture. It is essential that such spools be strong and uninjured by moisture and at the same time permit circulation of liquid and air through them and the fabric wound thereon.

' One object of the present invention .is to l0 provide a. spool of this character which embodies novel and improved features of construction which ensure strength, simplicity and cheapness yin manufacture, and durability. l5 Other objects are to provide a spool of the character described comprising a minimum number4 of .simple and strong'parts which can be easily and vquickly assembled; to provide such a spool including a tubular body, end plates and means for clamping said end plates together and to said body, said parts being of novel and im )roved construction whereby the body is securely clamped between the end plates against movement in all directions and said end plates are held in fixed relation to each other; to provide a novel and improved method of making a spool, and to obtain other results and advantages as may be 3U brought out by the following description.

Referring to the accompanyingdrawings,

, in which corresponding and like parts .are designated throughout theseveral views vby the same reference characters, Figure l is a side elevation of a spool embodylng the invention;

Figure 2 is a vertical long1tudinalsec tional view therethrough, taken on the line 2-2 of Figure 1;

Figure 3 is a fragmentary vertical longitudinal sectional view, taken on the line 3 3 of Figure 1;

Figure yl is a side elevation of the inner side of one of the end plates;

Figure 5 is a transverse vertical sectional view, taken on the line 5 5 of Figure l;

Figure is an' end elevation of the spool showing the outer side' of one of the end plates. v

Specifically describing the embodlment of the invention illustrated in Figures 1-6, inclusive, the reference character 1 designates the bod of the spool which is preferably in the p orm of a cylindrical tube, andy the. reference characters 2 designate endl plates which are of a diameter somewhat greater than that of the body 1 to serve as flanges for the body to retain fabric or the like wound thereon. The plates 2 are substantially identical in construction and each is formed upon one side thereof with a coaxial annular groove 3 of a diameter corresponding to that of the tubular body 1, so that one end of said body may be fitted into each of said grooves.

Each of the end'plates is also formed upon the side thereof in which the groove 3 is formed, with an integral co-axial boss lv through which extends a threaded opening 5. Said boss is preferably formed by stalnping or otherwise pressing the central portion of the plate from one side to theother, and the opening 5 may be formed at the same time and subsequently threaded; 'although the boss 4 and the threaded opening 5 ma be formed in any other suitable manner. he side of each of the plates 2 opposite that of the boss 4 is formed with a countersink 6 surrounding the corresponding end of the open ing 5, and this countersink may be formed in any suitable manner, for example by the pressing operation when Ithe boss is formed by stamping the latter from the plate.

A tie member 7 which is preferably in the form of a tube has its ends threaded as at 8 to fit the openings 5..- In assembling the spool, one end of the body 1 is tted into the' groove 3 of one of the end plates 2, the tie member 7 preferably having been firstA fitted into the opening 5 of the `end plate. The 90 other end plate 2 is then fitted upon the other end of the tie member 7 and screwed thereon until the corresponding end of the body 1 is fitted in the respective groove 3. By relative rotation of the end plates 2, the bod)1 is securely clamped between the end plates and the end plates securely fastened to each other. Obviously, the grooves 3 prevent lateral .movement of the body 1 relative to the end plates, and the tie member 7 prevents separation of the end lates from each other and from the body. he ends of the tie member are then ups'et or flared, as at 9, into the respective c ountersinks 6 so that the plates 2 cannot be nnscrewed from the tie member. It will be noted that the countersinkspermit of easy upsetting or'iiaring of the ends of the tie member 7, and the upsetP portion is wholly beneath the plane of the corresponding end plate.

Preferably the body 1 is formed with a plurality of rows of perforations 10 and the end plates' 2 are perforated as at 11. The body may also be formed Withv longitudinal grooves or corrugations 12 in which the openings 10 are formed, so that the corrugations at the same time serve to strengthen the body 1 and as passages for liquid and air to and from the fabric on the spool.

While I have shown and described one pre.- ferred embodiment of my invention, it will be understood that this' is primarily for the purpose of illustrating the principles of my invention, and that many modifications and changes may be made inthe details of cou-V struction of spools b those skilled in the art without departing rom the spirit or scope of the-invention. Therefore, I do not desire to be-understood as limiting myself except as required by the following claims when construed in the light of the prior art..4 v

Having thus described the invention, what v I claim is:

i -'1. A spool 'comprising a substantially cylindrical tubular bod a pair of end plates l of a diameter greater t an that of said`body and each lhaving a central threaded opening and a'countersink around one end of said opening, said plates each having a lgroove on y its face opposite said v'countersink to receive 3o one end of said body, and a tie vmember extending co-axially through said body and having its end portionsthreaded and each fitted into saidopening in one of-said end plates and its extremity upset into the corresponding countersink .so as' to overlieV said end. platev with the upset portion below the opening, means on said end plates for sup-v porting said l body co-axially therebetween,

`and atie member extending co-axially throughsaid body. and having its end portions threaded and each fitted into said openin in one of said end plates and its extremlty upset into the corresponding countersink so a's to overlie said end plate with the'xupset( portion below the plane of the corresponding side of said end late.V
