fiQUND-RECOBDING APPARATUS.

To all whom it may concern: a

lie it known that I, JOHN Norm, citizen of the United States, residing; at- Brooklyn, in the county of Kings and State of New York, have invented certain new and useful-Imrovements in Sound-Recording; Apparatuses, of which the following is a specification,

This invention relates to sound recording apparatus, and contemplates the provision of novel means embodying a telephone-and a phonograph for producing phonographie records of dictated matter in a more accu-' rate, convenii'mtand economical manner than has been heretofore possible.

i' honographs especially constructed for the purpose are extensively and successfully employed in olfiees and elsewhere for makin; records of dictated matter, which when repri'itluetvl, are written out by an operator. Such use of phonographs is subject to certain marked disadvantages, In the first place. the operator must provide a place usually near his desk for a cumbersome machine and for the cylinder, holders. and the like, and must provide electric current or other means of operating the mechanism or the phonograph. He must attend to the provi sion of hianlc cylinders, guard them with ainstaking care against the readily occurring surface mutilation, .looth before and after use on the phonograph, and generally loot; after them until they are placed on the reproducing 'mar-hine. l1in'thermore, the user inurattend to the placing of the records in the machine; he must adjust the stylus in position for work, and generally give his personal attention and his-time to the me hanical manipulation of the p honograph mechanism from the time he starts to dictate to it until the dictation complete.

it one of the important objects of this invention to overcoinethe above named dis- :IIlYill'littffls by wholly relieving the user of the huruen of personally attending to open ating the phonograph mechanism, siunilying and removing records, adjusting the stylus, and looking after the wax cylinders from the time they are shaved, until adiusted in position on the ri-zproducer.

iinolher important object of the invention is to provide convenient and reliable means for starting and stopping the rotation of the Specification of Letters Patent.

A. further object of the invention is to Eatented May 30, 1911.

Application filed January 31; 1910. Serial No. 541,145.

provide signal means to apprise the dictator when a cylinder is in position ready for use, and to notify him when the record on the machine to which he is dictating, is completed, and when such record. is'replaced by a fresh cylinder.

Other objects and advantages will appear in the course of the following description, wherein reference is made to the accompanying drawings, in which,

Figure 1 is a cro ss-sectifinal view showing several phonograph units and. the driving means therefor. Fig. 2 is a side elevation of a singleunit. Fig. 53 is a detail view of a coil operated clutch which I employ. Fig. 4: is a detail view of a slide rod for opening and closing the operative circuit. Fig; 5 is a detail sectional view showing the magnetic recorder and associated parts. Fig. 6 is a, detail view partly in section, of the transmitter standard and a signal lamp mounted thereon. Fig. 7 is a detail sectional view of the transmitter standard showing the switch mechanism mounted therein, and Fig. 8 is a diagrammatic view of the electrical. features of my invention.

My invention essentially comprises a telephone transmitter 1 and a receiver 2, both being of the usual construction, except that the diaphragm 30f the receiver carries centrally thereof, a stylus 1 adapted for contactwith the surface of a phonograph c vlin der 5, as shown. The receiver 2, wherein are supported the magnets G, is pivotally supported from a pin. or bolt 7, by means of an arm 7 extending between ears 8 inounted upon a sleeve 9, adapted forsliding movement along a supporting guide rod 10.

The receiver being freely pivoted onthe pin or bolt :7, presses the stylus 4 against the cylinder 5, as will be evident from Fig. 1.

A table or other suitable support 11 is provided and suitably secured upon this are the standards 12, 13 and 14, these standards beingdisposed as clearly indicated in Figs.

1 and These standardstsupport the guiderod 10 and a hollow rod or sleeve 15, in which is mounted a shaft 16, which is screwthreaded for the greater portion its length between the supporting standard 1.3 and 14-.

The sleeve is open at its 10 or side as indicated in Fig. 5 to permit-the arm 17 to' engage the shaft 16, The arm 17 is threaded at its 'free end for operative engagement. with the screw threads on tile shaft 18 to efieei; ceivei 'si'yl'os iengiiuoiim as will be more fully is .piyotecl i pin 18 pass fix 5 19 supported a siee've 20, which is iv he liaiiism as liereinizofore 7o tudinailymovable upon the sleeve fies need, and also to operate the gea -cram?

This occurs only. when the plionoi ruph cylinder has been entirely utilized. and :1 new cylinder is required. It will thus be seen that when the glow disuppezus from lump 63. it indicates to the dictator that he must suspend dictution until the operator at the phonograph end of the line removes the record and supplies a new cylinder. the sleeve 5) is moved into contact with lug 52 and the slidc rod 51 moved to thc leftv so that spring 5t, again contacts with spring: 5i.
