To all whom may concern:

Be it known that we, hnnnnnnni' 11mm and. Cumulus *Wnssmus, citizens of the United States of America, residing in iVoodhn-ven, in the county ofQueens and State of New- Yorh, have invented eerinin n0 nnd useful. Improvements in Grznnophones oi. which the following is a specification.

This invention relni'es lo an innfn'oved grznnophono of that type in which no rate nnd detachable horn is used, but in which the horn is pernuineni'ly located in a casing below "the l'eci'ird-cnrrying disk and its netuni'ing motor.

The separate and detachable horns used in phonogrnplnc apparatus heretofore, are

objectionable for he reason that ihey render the :jip nirntns cumbersome, :18 the horn takes up 1:. word deal of space, and as it i1npziirs lo some extent {he rlenrness of he delivery of the phonogrnphic records. ii}; dispensing with (he sepnrnie horn and ils supporting sinnd- (he eniire nppurnius becomes lnmdier. more conveniently lrnnsporinble and more easily siornhle when not reqinred for use.

This invention is designed. io furnish a phono g'rnphic npparuius in which the horn is arranged in n supporting easing below the recoiii-carrying disk and eonnecledwith :1 tubular tone-arm carrying the diaphragmloox by universal joint provided. with means for holdingthe tubular arm and (ii: phrugni-hox in raised position.

The invention consists fnrlher of certain details of CUIISil'llCilOll which will be fully described hereinafter and finally pointcd out in (he Cl-illl'1S.

Thecas' 1g C 18 made of rechingniar shown shape and of a snificiem size to permit the placing in the upper part of the same of n, soin'id-delivering horn H and other accessorics such as the record-cur disk or inrninhle l: and (he inoior for five same (not To the upper rear-end oi the easing C is applied a hinged cover C so that 'lhe rr owl-carrying dish or i'urniable D and um ione-nrin (6 with the dinphragni-box b all its front-end and the universal joint eon- IllJFiiUil with the horn H can be protected against dusland meddling when. not required for use. i

The lower portion of the spherical portion 6 extends into and opens into n tubular socket that is senled in fire top-pints of the casing at the T9111 of the (liSK'D.

The. spherical portion c of the iono-nrin a is fitted into the upper end of the socket a, so that the ions-urn: can, he run up and. down in foiiowinls; (he lilGi'iOl). of he stylus in the groores or deprc .IOHS of the record. ihc lower opei'i part of the s 'iherieul per-- ion 1; extends to some micii inio the socket u so as to irzinsniii; tin lillll'r i fl'l -li lifi into the inner or rennend of the horn ii con necized therewith as shown in i, The spherical portion a is preiiernhl v .nnide oi aluminum or oi'her ll lli niehii so to oii'er as hiiie re isinnee as pijlbfiiirh, h; ihe up and.

n; the inner end 0 arm and its spherical portion 6 rests by the shouldered dlsks 0 on the upper rim 6 of the socket and permits the easy swinging of the tone-arm in up and down, as well as in lateral direction, while the circumferential flanges of the disks act as guardflanges for keeping the spherical portion on the upper end of the socket 0 The spherical portion 6 of the tone-arm a in connection with the shouldered rim e and the flanged disks 6 moving over the rim form a kind of universal joint for permitting the free and easy movement of the tone-arm together with the diaphragm-box and stylus at the front-end of the same in following the depressions of the record, withoutexerting any strain on the needle or stylus. The diaphragm-box and its needle-holder are made in the usual approved manner.

The universal joint between the tone-arm and the socketat the inner end of the horn follows the motion of the needle or stylus in the grooves of the phonographic record, so

that the sound-waves embodied in the grooves are transmitted to the enlarged outer end of the horn.

The lower part of the case C ispreferably utilized for the storage of records in the spaces formed between vertical partitions C The outletopening of the horn and the partitioned space at the lower part of the casing may be closed by means of hinged doors in the usual manner, so as to permit the closing of the casing and prevent the entrance of dust into the horn and the partitions C in the lower part of the casing.

When it is desired, toreplaee a record by a new one, the tone-arm a is raised and retained in raised position by a hook f which is fulcrumed to the shouldered rim 6 of the socket 6 which hook engages a segmental shoulder f at the rear of the spherical portion e, as shown in dotted lines in Fig. 4.

The hook is weighted or spring-actuated at its lower end. When the new record'is placed in position on the disk D, the hook is released from the shoulder f and the tonearm and diaph cagm-box are returned into lowered or normal position, the stylus being of the horn, and a pair of rollers for sup- I porting the inner end of the tone-arm.
