SPOOL OR REEL Filed May 15, 1951 Patented Feb. 16, 1932 UNITED STATES PATENT OFFICE D'ITO A. BOESEL, F ANSONIA, CONNECTICUT, ASSIGNOR TO THE E. A. MATTHEWS MANUFACTURING COMPANY, 01 SEYMOUR, CONNECTICUT, A CORPORATION SPOOL OR REEL Application filed Kay 15, 1931. Serial No. 537,651.

This invention relates to improvement in spools or reels and particularly to such as are formed from sheet-metal and adapted to contain tape, wire, and various other materials.

These spools usually comprise a tubular core with disk-like ends applied thereto, and in some uses of these spools they are subjected to considerable strain, so that it is neces sary to form them from comparatively heavy material or to reinforce the parts. The object of this invention is to so construct the core and heads that they may be readily as seinbled and will withstand the strains inrposed upon them, and the invention consists in the construction as hereinafter described and particularly recited in the claim.

In the accompanying drawings:

Fig. 1 is a side view of a spool or reel constructed in accordance with my invention;

Fig. 2 is an end view of the same; 7

Fig. 3 is a face view of one of the ends detached;

Fig. 4 is a perspective view of the core detached;

Fig. 5 is a sectional view on the line 55 of Fig. 2;

Fig. 6 is a sectional view on the line 6-6 of Fig. 2;

Fig. 7 is a sectional view corresponding to Fig. 5, showing the tongues turned inward;

and

Fig. 8 is a sectional view corresponding to Fig. 6, with the tongues turned inward.

In carrying out my invention, I form the core 10 from a strip of sheetmetal rolled to form a tube, or the core ma be drawn. The ends of the core will be provided with tongues 11, and preferably on each side of the tongues the end of the core is formed with notches'12. The ends 13 are also formed from sheetmetal, and preferably the edges 14 are rolled forming recesses 18 of a depth corresponding to the thickness of the tongues 11 and into which recesses the ton ues 11 are turned, and the edges of these into the spaces formed by the notches 12,

. so that the tongues 11, resting in the recesses 18,tend to prevent the ends turning on the tubular core, and the sides of the recess extending into the spaces formed by the notches 12, also hold the parts against turning one upon the other. The tongues may be turned outward, as shown in Figs. 2 and 6; or inward, as shown in Figs. 7 and 8.

This construction not only rovides a rigid spool or reel, but also by orming the recesses into which the tongues extend, there are no projections beyond the surface of the ends, so that paper disks containing printed matter may be readily ap lied to the ends.

It is obvious, wlthOllt'l lustration, that the notches 12 may be omitted, as the tongues turning down into the recesses formed in the ends will prevent the ends from turning on the core and avoid shearing of the tongues.

I claim:

A spool or reel comprising a tubular core formed at its ends with pro'ecting tongues and with notches'on each side of the said tongues, and ends formed with slots through which the tongues extend and with recesses around said tongues, said recesses forming epressions extend projections adapted to enter the notches formed in the ends of the core.

In testimony whereof, I have signed this specification. OTTO A. BOE SEL.
