INVESTOR Dec. 30, 1930. H. R. NAYLOR PHONOGRAPH BEZEL Filed DeC. 1, 1928 ligatented Dec. 3Q, 193@ 'r orales HENRY RODLEY NAYLOR, OF SEYMOUR, CONNECTICUT, ASSIGNOR TO THE H. A. MAT- THEW S MANUEACTURING COMPANY, OF SEYMOUR, CONNECTICUT Pl-IONOGRAPH BEZEL Application 1ed December 1, 1928.

This invention relates to the manufacture of bezels for phonograph turn-tables. These bezels are employed a` finish and as a.

means for securing the edges oi' the felt or 5 similar covering on the turntable. lt is recognized that such bezels should be strong, so that they can be applied with considerable force over the rim of' the turntable and that they should be in perfectbalance so as not to throw the turntable oil balance.

To meet these requirements, the bezels have 'Y usually been constructed heretofore by punching out a blank of sheet material large enough to form the bezel and then punching out the center of this blank. As only a narrow rim of metal is required, this punched out center is the greater portion of the blank. Sometimes these centers can be used for other purposes, but in many cases they constitute just so much waste.

lt has been proposed to make the bezels or" cstrip material, soldering, welding or brazing the ends of the strip together to form the complete ring. This however, has not been entirely satisfactory, because of the weakness and uncertainty of such joints, the skill and expense required for the production oi such joints and the olf balance condition which these joints impartto the strncture.

'lhe objects of this invention are to provide a bezel, which will meet the requirements above set forth and at the same time be free of the object-ions recited, possessing the 3" requisite strength and balance and being inexpensive and easily manufactured without waste.

These and other desirable objects are attained in this invention by forming the blank from which the turntable is made with a flange which is deeper than the flange required for the table by an extent sufficient to form a bezel for the table, this bezel portion .1, being larger than and connected with the flange portion which remains attached to the table by a lateral shoulder and then severing this bezel portion ot the flange at the shoulder to thereby provide a detached ring which will lit over the table flange and which has, by

serial No. 323,031.

reason of the shoulder, a narrow bezel po"- tion to overlie the rim of the table.

Various other novel features of the invention will appear as the specification proceeds.

The drawing accompanying and forming part of thespecification illustrates a practical embodiment and method of manufacture of the bezel, but it should be understood that the structure and process may vary as regards this particular disclosure without departure from the true spirit and broad scope of the invention.

F ig. l is a broken and part sectional side view of a. phonograph turntable with the new bezel; Fig. 2 is an enlarged'detail sectional View of the bezel and rim portion of the turntable; F ig. 3 is a sectional view illustrating the turntable in process of manufacture with the bezel extension of therim liange still attached Vto the turntable blank; Fig. si isa sectional detail illustrating the pinching off operation of severing the bezel portion from the rim flange portion of the table.

ln Figs. l and 2, the bezel is indicated at 5 in the form of a narrow band encircling the dependent iiange 6 of the turntable 7 and having a narrow inwardly projecting annular bezel portion 8, overlying the rim of the table sulciently to frame7 the felt or other covering 9. Y

To produce this continuous one-piece bezel, the blank from which the turntable is made, is formed, as shown in Fig. 3 with the dependent rim flange 6, and in addition to that with the enlarged extension, providing material 5, for the bezel an connectedA with the norma-l flange material 6 'by an annular shoulder, providing material 8, for the flange of the bezel. Then this eXtra portion of the table flange is severed at the shoulder 8 substantially on the line 11 in pinching off dies l0 or the like as indicated in Fig. 4l, to leave the turntable blank with the rim flange 6 and to provide as a separate part the bezel to fit the turntable.

In shaping the blank shown in Fig. 3, the bezel portion of the table flange is made sufficiently larger than the diameter of the table to properly t down over the table and its covering and the shoulder at 8 is wide enough to afford sufficient depth for the flange of the bezel. The bezels need not necessarily be combined with the tables from which they are cut as the parts can be made with sufficient uniformity to insure interchangeability.

In drawing the table with the deeper flange required to provide the bezel material, there is a thinning out of the flange, but this is not objectionable, as the bezel may be of lighter stock than the original turntable stock. In the shouldering and. drawing operations, the working of the metal compacts and strengthens the material so that even if lighter than the original turntable material, the bezel amply strong enough to serve its required purposes.

The turntable may be produced' first by a blanking out and then a shaping up press operation, in which the shouldering and flange enlargement are effected as continuations of one and thesame forming operation. The deeper flange of the turntable blank. which may be as much as double the usual flange depth plus the amount of the lateral shoulder, may be worked up from the material of which the turntables are usually made. To lessen the drawingoperation, the turntable flange and bezel need not be made quite so deep as usual, or one may be made shallower than the other. For la particularly shallow bezel, the material for the bezel might be taken from the material provided for the rim flange. sacrificing the depth of the rim flange to that extent. Thus, turntable blanks produced by prior methods and having the usual depth of flange might be shouldered and enlarged according to this process to form the bezel material, which could then ber pinched off according to this-process. rlhe extra material required for the bezel however is relatively so ineX- pensive and the forming operation is so simple, that in practice the turntable blanks are usually made with substantially the same normal rim flange plus a su'liicient amount extra to provide the full depth bezel.

The annular shoulder and edge enlarged ment of the flange are readily formed without straining or tearing the material, while these parts remain attached to the initial or main body of the flange.

In drawing up the double flange or the table, the annular shoulder isV purposely thinned somewhat as indicated in Fig. 8 and the shoulder is clipped in this thinned portion. This leaves the bezel with a thinned bezel flange 8 of substantially the same inside diameter as the diameter of that part of the table flange 12 from which it is severed. As

clearly shown in Fig. 2 this bezel flange lies `close against the table top and forms practically a continuation of the line of the felt. Also in drawing the flange, the inner edge of the main flange where it merges into 'the shoulder is outwardly curved at l2 and the lower inside edge of the bezel flange is rounded out at 13 to eliminate burrs or sharp edges. The small annular rim or remainder of the shoulder left on the edge of the table flange partly closes up the gap between the lower edge of the table flange and the bezel, as indicated at 14 in Fig. 2.

'.lhe severance of the stepped flange in the intermediate thinned portion of the step makes thel shearing action easy and positive, due both to the lesser thickness of material and to the presence of shearing shoulders at opposite sides of the material which is cut.

lfhat is claimed is:

l. in coniibination with a phonograph t urntablc, having a dependent flange with a sin all outwardly turned rim at 'the edge thereof, a Continuous one piece bezel engaged over said flange and having a smallthinned inwardly turned bezel rim at the upper edge thereof".

2. ln combination with a phonograph turntable having a dependent flange with a small outwardly turned rim at the edge thereof, a continuous one piece bezel engaget'i over said flange and having av small thinned inwardly turned bezel rim at the upper edge thereof, the rim of the table flange being rounded outwardly at the lower edge thereof toward the lower edge ofthe surrounding bezel.

3. In combination with a phonograph turntable having a dependent flange terminating in an outwardly turned annular rim` a cover on said turntable and extending down over the flange toward .said out-turned rim and a continuous one piece bezel engaged over that part of the cover surrounding the flange and having at its upper edge an inwardly turned annular bezel rim having an inside diameter substantially the same as the outside diameter of the outturned rim oil' the flange. Y

4l. ln combination with a phonograph turntable having a dependent flange, a one piece continuoiisly integral bezel of large enough diameter to pass down over the flange of the turntable and having an inwardly extending annular bezel rim of an internal diameter, substantially corresponding to the external diameter of the edge of the turntable flange.

In testimony whereof l affix my signature.
