Application filed January 4, 1924:, Serial Ito. M4354. ltenewea September 11, 1925.

To all whom it may concern:

Be it known that l, Rossnnn H. Bowen, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented 'certain new and useful improvements in Methods of Securing Together the Component Parts of Metallic Spools or Heels and Apparatus Useful to This End, whereof the following is a specification, reference being had to the accompanyin drawings.

This invention is concerned with securing together the component parts of metal lic spools or reels oil the type wherein the barrel member is provided with projections or tabs engaging in apertures of the opposite'end flange heads. In accordance with the usual method employed heretofore in accomplishing this purpose, the portions of the tab ends projecting through the flange heads were upset or riveted by manual hammering, or by use of a power press to the together the component parts of a spool or same end. This rocedure was often at tended by distortion of the spool barrel especially in the case of spools-or reels constructed from comparatively thin sheet metal. I

The purpose of my invention is to over come the objection above pointed out, and this desideratum ll secure by heating the projections or tabs suihciently to permit of their being subsequently upset or spread by application of light pressure.

In the drawings, Fig. l is. a perspective view of the type of spool or reel to the assembling of which my invention is directed, one of the end flange heads being shown separated from the associated parts so as to avoid concealment of the charac teristic details of the structure.

Fig. H is an illustration in vertical sec tion showing more or less diagrammaticah ly, a typical embodiment of the apparatus of my invention with the spool or reel assemblage in place in readiness to be op" erated upon; 1

Fig. lll shows, in end elevation, the appearance of the spool or reel after its cont ponent parts have been permanently secured together in accordance with my in vention; and Fig. IV is a detail. sectional view on anenlarged scale taken as indicated by arrows llV-lV in Fig. lll. The spool or reel shown in Fig. l of the drawings comprises a barrel member 1, and separate end members or heads 5, 5. The barrel member 1 is fabricated from a sheet metal blank having integral short prolongation tabs 2 at intervals along opposite side edges, said blank being bent to cylindrical configuration WlllllltS ends meeting along a line 3. The heads 5 are like-- wise struck from sheet metal," the edges of the circular blanks from which they are formed being rolled to provide peripheral stifiening beads 6. Each head 5 has a concentric series of apertures 7 designed to receive the tabs 2 of the-barrel member 1, and also a circumferentially flanged cen tral aperture 8 so as to be mountable for dle.

The apparatus by aid of whichl secure reel such as described above includes, as

illustrated in Figzll of the drawings, a-

metallic plate 10 that serves to support the spool reel assemblage in vertical or end-on position with one of the heads 5 resting.

directly upon it. The upper face of the plate 10 is formed with concentric circular relatively movable electrodes such as shown at is in the illustration. The electrodes 1a are preferably made cylindrical with their rotation upon an appropriate axis or spinthe ends tapered as shown for operation upon the tabs 2, and any suitable means may be provided for their guidance and actuation placed as shown in Fig. ll and an electrode J apparatus as illusinthe manner hereinafter noted. The elec-- trio circu t previously referred to has interposed in it an appropriate switch 15 for conl t in contact an exposed projecting tab tirel end 2, the switch 15 is closed. When the tab 2 has been heated to vthe extent of rendering the metal semi-molten, the switch 5 is opened to intercept further flow of current in the circuit,, and sufiicient pressure is thereupon applied to the electrode 14 to spread or upset the softened metal within and over the flared aperture 7 of the head 5, the result of this procedure being shown in Figs. III and IV, The final step in the operation, it will be readily appreciated re quires application of but slight pressure as compared to the blow of a hammer or to the action of a power press so that the possibility of distorting the barrel is enobviated. The shutting oii of the heating current before the upsetting pressure is applied not only avoids needless heating of the head 5 and consequent risk of overheating and deformation, but also obviates risk of collapsing the spool end by excessive pressure of the electrode is combined with over-prolonged heating When the tabs 2 at one end of the spool or reel 1 have been upset as just explained the assemblage is inverted upon the plate electrode 10 and the operation repeated precisely as before,

Having thus describedmy invention I claim:

l. The herein described method of as sembling an all metal spool or reel where n the barrel portion is provided with tabs engaging through apertures of the end flangeheads, which consists in electrically npsetting the protruding ends of the tabs by combined application of heat and pres sure the protrudis softened,

heating curthe flange head members, the combination of a plate electrode for supporting the spool or reel assemblage end-on, and an opposin electrode movable into contact with the tabs projecting through the opposite end flange or head of said spool or ree at. In apparatus for securing together the component parts of a sheet metal spool or reel wherein the barrel portion is, provided with prolongation spuds engaging through flared apertures in the flange head members, the combination of a plate electrode for supporting the spool or reel assemblage end-on, said plate electrode being concentrically recessed to accommodate a peripheral head of the near flange head and the aforesaid tabs projecting therethrough, and

opposing electrode movable into contact with the tabs projecting through the opposite end flange head of the spool or reel.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyl- Vania this Q'Zth day of December 1928.

RUSSELL I BUWTEN.
