To all euhm/t 'it may concern:

lie it known that l, EDWARD il. Escursione, a citizen of the United States, residing at Philadelphie, in the State of Fennsyivania, have invented a certain new and use'ilil lmnrovement in Tallgiiig-ll/lachines, whereof the 'following is a specification, reierenceloeing had to the accompanying drawings.

My invention relates 'to sound recording and reproducing machines, including,l gramophones and `rgraplroplumes; and particularly toed mechanism tor sound bones of such ma chines adjustable to automatically repeat their cooperation with a given sound record, at the Awill o'j the' operator.

its 'hereinafter described, my invention is specifically adapted for such machines ar tinged to cooperate withf flat disk records, and having sound conducting tubular arms. or horns which move with thesound noxes', and are so constructed-and arranged lthat repetition oi the coperation oit the sound hun with any given record f s consequent upon such movement, to an adjustahly predeter mined extent.

This is a division of my epplication Serial 175,082 .tiled d une 16, 1917, tor Letters Ratent oft the United States, showing; forms oi? my invention as respectively embodied in a grapliophone and in a gremophone and 1 nd it convenient to illustrate and describe the torni of my invention herein claimed in oonnection with a grainophone oi the type known commercially as -a 'Llictor talking machine. However, 'it is to he understood that 1 do not desire to limit myself to such specitic embodiments oi rny invention, which includes the various novel features oi conn struction and arrangement hereinafter ruoter definitely speciiied. i

llt may oe observed that although the embodiment otb `my invention chosen for illus'- tration herein is specically different from the Aform oi' my inventionsliosvn embodied in u lo raphophone in my original application, and specifically claimed therein, they each include means to vurialoly predetermine they initial and terminal positions of the respec-f tive sound boxes with reference to given sound records, in combination with a single rotary cam constructed and arranizcd to automatically lift the sound hor; from eofl'uperu tive relation with the record when itreaches a variably predetermined terminal position and to then return the sound hox to itsinitial position and again lower it into cooperative relation With the record; said earn having the capacity to shift said sound box,

throughout the maximum range ot' its movenient, hy trietional engagement with a cam plate carried with lthe sound box,- lout its eiffective capacity is adjustahly variable in accordance 'with Variations in the extent ot ditferent sound records.

ln the drawings; Figure l is a plan view iof thefiictor gramophone aioresald'having 'afcornf4 nient embodiment oi my invention in eonneetion therewith. Fig. 11 is a side elevation of said machine shown in Fig. l. Fis'. liti' is a full size plan View of the automatic teedmechanism indicated in Figs. l and ll., and Fig. IV is a left hand side elevation 'of seid mechanism. Fig. V is a sectional View i said mechanism, taken on the line V in tFig. Hl. Fig. V1 is a fragmentary sectional il view, taken on the line Vl in Fig. Hl.

in' 'said figures: 1 is a .casing inclosinlq` a gramophone including the record turn table arrenged to loe turned by the motor 3 which is only indicated in dotted lines in Fig. Il

but is mounted upon the underside of the easing top t whichI is detachebly rigidly secured on said casing 1. The sound looX 5, which is carried by the tubular tone arm (3, includes u Vibratory diaphragm and carries the stylus il, indicated in Fig. lll, arranged to traverse a groove in a record 9 on said turn talole 2 and automatically shift said 1oox toward 'the axis of said table. '.lhe amplifying horn 10 is rigidly connected with said casing l but is pivotally, eonnectedwith said tone arm G at 11.

The collar 12, Whicl'i is detaehaloly secured upon said horn 1() by the set screw `13, ourries the adg'ustable initial stop lever 14 which is arranged to be manually secured in adj usted position by the set screw shown in Figs. l and lil. Said lever 14 rests upon y the flange 16 of said collar 12 which is conveniently graduated aslindicated at 18 in Fig. lill. so es tn be traversed by the index lug 19 on 'lever 14; whereby the posiot said lever may* be accurately determined so ts to limit 'the initial position of titi ino
