This invention relates to paper spools, and

has for an object to provide an.,improved construction wherein a comparatively strong structure is reduced at a minimum expense.

Another 0 feet of the inventiondsto provide a paper spool wherein the minimum number of parts are used and yet the spool is (ilformed with extra reinforcements at each en In the accompanying drawings- Figure 1 is a side view of a paper spool disclosin an embodiment of the invention,

art of t e same being shown in section for tter illustrating the construction;

Figure 2 is a sectional view taken from Figure 1 on the line 2-2;

Figure? is a view similar-to the left hand end of Figure 1 but showing a modified form of the invention.

'Referri to the accompanying drawings by numera s, 1 indicates the body or barrel of the spool, and 2' and 3 the ends. The thickness of these members and of the other members have been somewhat exaggerated in order to better illustrate the construction,

butit will be understood that these members and the other parts may be made of any desired thickness and size without departing from the spirit ofthe invention.

The barrel 1 is preferably a complete tube and the ends 2 and 3 are separate discs held to the tube by a hollow rivet 4 which is associated with reinforcing and connecting sleeve 5. The sleeve 5 is formed from a section of paper tubing and is bent into substantially the shape shown in Figure 1. This may be done by any well known means,-and after it has been bent it is inserted as shown in Figure 1.

Before the insertion of sleeve 5 the interior of the barrel 1 is provided with a layer of glue 6 at each end, and then the tubular members 5 are inserted to substantially the position shown in Figure 1.

Preferably in assembling the parts the sleeve 5 is first riveted to the end 2 or the and 3, as the case may be, and then the interior of the ends of the barrel supplied with glue or other adhesive. After this has been done sleeve 5 with its end is slipped into position as shown in Figure 1.

Both ends may be placed in sition at the same time, but preferably on y one end at a time is inserted, and after it has been slipped into osition the barrel l'is set in vertical position with the end down, whereby the adhesive that has been pushed inwardly when sleeve 5 has been inserted will gradually gather and form a-lump 7. This been inserted and the glue dried, the other end is inserted and allowed to become dry.

After the spool has been thus completed it is read for use. and by reason of the sleeve 5 the en s are strongly reinforced and consequently the spool as a whole is extra stron Preferably all parts are made of paper wit the exception of the rivet 4 and the Inc 6.

In Figure 3 a modified form 0 the invention is shown, where all the parts are similar to that shown in Figure 1 exce t the sleeve 5' which is in the shape of a b diametrically opposite ends cut off, end 8 presenting a larger opening, while end 9 is clamped by the rivet 4C This method of forming the sleeve 5 is such that the aper tube used may be more quickly (presse into sha e and just as easily inserte n this form of sleeve there are no sharp turns'and consequently none of the fibre of the sleeve is broken, which might be the case in sleeve 5 with the first structure unless some care was used in the formation of the sleeve. However, if this takes place it will not affect the usefulness of the spool as there is ample material to act as a connecting member and also as a brace.

After the parts have been assembled and with the glue dried the spools are then ready for a a q l assaua at each end of said barrel fitting snugliy therein, each of said sleeves having aturne v in end fittin flatwise against the end disk a hollow e e et extendin through each of 5 said turns -in ends and t rough the respective disks, each of'said eyelets having a flange I at each endfor clamping the respectiveend disks to the respectiveturned-in ends of said sleeves and adhesive for securing the respective sleeves to said barrel. I I 2. A spool com rising a tubular barrel, a pair of end disks aving'perforations there- .m of less diameter than the internal diameter of said barrel and means for securing each of said end disks to said barrel com risin a tubular sleeve snugly disposed within sci barrel at the end thereof and adapted to ex tend from said end inwardly toward the intermediate portion of said barrel. an-internal radialflange formed at the outer end of said sleeve, and adapted to fit flatwise against the inner surface of said end disk adjacent said rforation, the inner periphery of said ange defimng an aperture coextensive with 95 said perforation in said end disk, and a hol low eyelet extending through said aperture and said erforation, an outwardly ,extending radia flange formedon each end of said eyelet for clamping the end disk to theradial v flange of said sleeve and ineans for rigidly v securing said sleeves to said barrel.-
