HARRY IB. MCNULTY, OF EAST CLEVELAND, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS,

TO THE UNITED STATES PHONOGRAPH COMPANY, 0F CLEVELAND, OHIO, A CORPO- RATION OF lOHIO.

PHONOGRAPH.

To all whom t n ay 'concern Bc it known hat I, HARRY B. MCNULTY,

'a citizen of the United States, and a resident of East Cleveland, county of Cuyahoga, and Sta-te of Ohio, have invented a new and useful Improvement in Phono-- graphs, ot' which the following is a'specitication, the principle of the invention being herein explained and the best mode in which l have contemplated applying that printwo minute and four minute records.

To eil'ect such adaptation of the machine, it is necessary that the reproducer be fed along the record at a different rate 0f speed in each case, and that a stylus of a vdiii'erent character, corresponding to the tineness of the thread, be properly positioned in the one case to play o-n the tine thread, in the other upon the coarse thread. One form of mechanism for conjointly eiecting thel two adjust-ments referred to is illustrated in my co-pending application, Serial No. 463,942, filed November 23, 1908, and the present invention is in part an improvement of such earlier mechanism, and in part an adaptation of the same to several variant forms of reproducer from thev preferred form there" shown. l

, Said invention, then, consists of the means hereinafter fully described', and particularly pointed out in the claims.

The annexed drawings and the following description sc t 'forth in det-ail certain mechanism embodying the invention, such disclosed means 'Y constituting, however, but several of thefvarious mechanical forms in which the principle of the invention may be used.

In said annexed drawing -Figure 1 is a transverse sectional view of ar phonograph embodying my several improvements in one approved form; Fig. 2 is a similar view of the reproducer andihat portion of the carriagev in which said repreducer is seated,

showing parts of the lattern a diefeent opspecification of Letters raient.

l; Fig. 3 is a bottom plan view of an actuating cam member that forms a feature of `the machine; Figs. 4, -5 and 6 respectively illustrate 1n diiferent operative positions, a

development of one of the cam elements of such cam member; Fig. 7 is a perspective view of another detail of the machine,'viz.-

the key whereby the adjustment of the reproducenstylus is secured; Fig. 8 is a secves tional view of the reproducer and the portion 'of its carriage corresponding to. that of F1g. l but showing the adaptation of my invention to a diiferent construction of stylus lever; Figs. 9 and l0 similarly illusother forms of stylus lever; and Fig. l1 shows a `det-ail of t-he construction of Figs. 8 and 9 in modified form.

AIt has not been deemed necessary for prestrate the adaptation of such invention to ent purposes to illustrate the general construction of the phonograph in greater detail than. is aorded inthe sectional view of F ig. 1 wherein the supportfor the record receiving mandrel A 'is not shown, but merely its position relatively to the base A. and to the ways a upon which is slidably .mounted the carriage B for the reproducer. Movement of this carriage along such ways is secured by connectlng the same with v one or the other of-two feed screws C C lying below and parallel with its direction of .movement, such engagement being had .by

means of plungers B B2 recoprocably mounted in the carriage, the lower ends ofwhich are in the form of sectional nuts gage the upper ends Z2 b pf t-he plungera4 respectively.

The disk B3, in the form shown, isv a composite construction, being made up of an uppersection bearing' the cam 64 Vjust reerred to, and a lower section incased within the carriage body. Such. lower section 1s, however, fixed to the upper section so as to `rotate therewith, justas though said sections Were integral.

.,JThe. under face of the lower section of camdisk B3 (see Fig. 3) is provided with a raised edge b'forming a cam adapted to laterally engage a key D that is both rota- 5 tably and longitudinally'movable within a sleeve D -pivoted to the under side of the rearwardly projecting annular portion B4 of the carriage wherein the reproducer E is seated when inuse. Disk B3 is further provided. with a heart-shaped cam b that is adapted to terminally engage said key D to advance the same. A tension spring d. con.v

nected with'the' outer end of the key's'erves both tolretract it and to depress its outer.; end against the operation of the cam ele':

inents'just referred to. Such raised cam edge b? however, is formed at substantially opposite points vin its extent with notches b that permit the lowering of the outer end 2b of the key at fthe same time that its retraction is rendered possible by heart-cani bs, such position ofthe two cam elementson the under face of the disk corresponding with the position of the cam b4 on its upper face '5 that permits operative engagement of one or the other of the two spring pressed plungers'B B2 with its feed screw C or C. Intermediate between the two notches b in cam 71", so as to correspond with tha forwardly extending lportion of heart-cam bs,

is a radially disposed pin '61 that engages a forked arm d on the rear 'end of the key.

I so as to rotate thelatter first in'one'fdirection, and then inthe other, depending upon the direction of movement of the cam member B?. The amount of. such rotation is accurately' determined by'means of two notches cl2 properly spaced about the inner end of the sleeve D', and adapted to engage a pin 40 Z3 bornef'on the side of the key (see Fig. 7). The portion of the sleeve lying between the two notches being suitably beveled, makes it necessary merely to carry the key in its rotative movement past the center of such pin to insure a proper'p'ositioning of the key, and of the stylus lever or actuating element W'itli'which'` the same engages, as, and for the purpose-now to beset fort-h.

The 'general construction ofl the reprod meer E ustrated in Figs. l and 2, is the same ast-hatshown in the co-pendino ap- V plication previously referred to, an includes a diaphragm (not shown), a floating weight E, a tubular lever e pivoted to said 35.5 weight vand connected to sald diaphragm,

and a stylus holder erotatably held vin said lever and provided at its forward end with a plurality ofstylusese2 adaptedE to opera- 't-ively contact with a record upon the mandrel Af in different positions of said holder respectively. The rearwardly projecting end ev of the holder is madev angular to receive the end of the key D when the latter is thrust forward, or advanced, bythe con- 6'5- jointly operated cams on the upder face of *feed-screw.

Y." The'modificationillustratedin Fig.- 8 lies,V

.the stud e5 with a gear e and journal in suitthe disk B3, fhe'prelimiiry estimada- Of such key` serving to raise the weight into the positionshown inA Fi 1, whereby the v'key and the stylus hol erl are properly alined forv the purpose in question. Pending such engagement, the rotative movement of the key takes place, andas a result, one

or the other of the styluses is brought, into said voperative position, depending upon the direction of said rotation. Thisy movement obviously will be correlated with the movement of a spring-pressed plunger B. or B2 into engagement with the .corresponding as has been-previously mt11nated,'1n the construction of the stylus lever which here is shown asa bar ofthe prevailing form.` In the oterend of the bar is rotatably mounted a vertically disposed transverse 'stud e5 85 that forms the stylus holder, the latter. bearing the two styluses, e2 one of which is suit-14 able for operating on anl Ordinar record .of threads per inch,- and the ot 1er operating on a record having 200 threads per inch. The specific construction of such stylus holder, it may be remarked, forms no part of the present invention, being shown in fact alongwith the two forms of Figs. 9 and 10, in U'. S. Patent No. 904,884. To au- 95 tomatically effect rotation of suoli stylus holder in a manner similar to that just described in connection with the preceding form of holder, I provide the upper endv of 100 able bearings on the'under side of the fioating weight E a shaft or spindle e7, the outer end of which bears a worm es that is adapted to mesh with said gear in the`raised position of the stylus lever illustrated in .the figures in question. The rear endof spindle c7 corresponds with the rear end of the stylus holder in the preceding construction, and is made of similar angular form, so that the key operated by the cam member 11o B3 is adapted to function in the same manner as before, first toraise the weight, and then to advance into engagement with, and

to rotate the spindle, withthe result that the stylus holder is likewise rotatedto bring first the one, and then the other of the twol styluses e2 into desired operative position.

The 'stylus holder in the reproducer of Fig. 9 consists of a horizontally disposed transverse stud e, which otherwise operates 12o the same as thatof Fig. 8, only la slight modification in the arrangement of the gear elo on thestud and of worm es on spindle e. being necessary. The same is true of Fig.

10, wherein the holder'consists of a sleeve 125 en rotatably mounted onthe forward end of the lever and previded with a spur gear e with which a pinion e, taking` the place of worm es on the forward end of spindle e7'is adapted to mesh. 130

" such a rack and pinion it Will obviously be shaft, or

possible to secure a com lete turn of the even more, shoul this be found desirable. l
