features of. this construction may be used inyarn-spools for other apparatus as well.

According to previous commercial practice, yarnspools have commonly been made of solid wooden cylinders to whose opposite ends were lued, or otherwise secured, disks of larger iameter to form flanged heads, journal pins being inserted at the opposite ends axially of the spool to support the same.

The present invention is intended to provide a. yarn-spool that is very strong and durable and at the same time is light in weight which is a material advantage'especially for yarn-spools used in tube frames. To cause satisfactory adherence of the yarn ends to the barrel of the spool, when the yarn thereon is nearly exhausted, I provide the metal or tubular barrel with a special surface ada ted to promote adhesion of the yarn to the arrel so as to prevent slip.

These and other features of the invention will be explained in the'following specification and will be defined in the claims hereto annexed.

-In the drawings l have illustrated various forms of construction and arrangement embodying the principles of this invention, in which:

Figure *1 is a side elevation of a complete spool embodying the features of my invention, a portion of the barrel and one head being shown in central cross Section.

Figure 2 is a transverse sectional view of the spool shown in Figure 1.

Figures 3 and t are longitudinal central sections showing modified forms of the spool lid head.

Fi ure 5 is a cross section showing a modisurface-which, in this case, comprises a .sheet of emerycloth, sand paper or the like, as shown at 2, which is wound snugly around the barrel between the heads and'may be glued or otherwise secured thereto to. main-' tain it in firm and smooth engagement with the barrel.

The heads or flanges of the spool comprise an outer or flange ring 3, having an outer flange 4 and an inner'flange 5, extending substantially parallel to the axisi of the spool, the inner flange forming 'a snug fit over the outer end of the barrel.

The inner member of the head com rises a rin 6, having an axially extendin ange 7 whlch fits snugly inside of the on of the spool barrel.

hen the spool head members are assembled in operative position, as shown in Figure 1, they may be spot-welded or otherwise rigidly secured to the interposed end portion of the tubular barrel.

The central open-ingthrough the inner head is of'a'size adapted to receive a. tubi'r lar socket '8, which is provided with a shoulder 9, abutting against'the outside face of the head 6. The outer edge portion of the To provide still furtherstifienin for the v structure the inner head 6, is provi ed with V an inwardly projecting flange 6, extending a short distance along the exterior of the socket to aflord elongated support thereof.

The formof head shown in Figure 3 shows a somewhat difi'erent form of bracin the Socket member 8, and. in this case the inner head 16 is provided with an outer flange it"- for attaching it inside the barrel. in the central opening of the head '16 is secured, b spot-welding or otherwise, a' flanged tube 1 whose flange lies against the inside face of the head 16 and whose tubular portion projects outwardly beyond said head to sur-- round and support the socket member 8 containin the journal pin 10.

In t e form shown in Figure 4, the inner ill) head 16 has the same construction as the rel and a spool supporting journal mounted form shown in Figure 3, and has attaching centrally of said disk to-rotatably support channel rings 20 and 21, rigidly secured to said spool, substantially as described.
