of the drawings, reserving it tothe claims to point out the novel features and tedehne the scope of the invention, itubeing umlerstood that the clanns will be given the due range ci' equivalents to which theymay he entitled in view of the art.

The instrument has a segmental shaped casingand is like a consol table supported on legs, lout this particular forni is, of course, innnaterial. The lett hand end of the casis reserved for the rnotor 1, turntable 2,l reproducer 3, and tone arin a, and the right hand end for the horn 5. 6 is a horizontal shelf supported intermediate the top and hottoin of the casing. Below it is the motor and through. it vertically extends the spindie T of said motor, on whose upper end above the shelf is-the usual turntable 2 to support the' record disk 8. ln Fig-.1, the reproducer l is shown with its stylus in operative engagement With the record.v

The horn may' have the rectangular cross section shovmfin Fig. 11, and loe made of suitable sheet metal and ina-ivv have the round sectioned small eno'. or neck 9 which curves upivardlv through a re'lativel1 much larger hole 1U 'in the shelt` 6, so that there is anv 'air clearance all around it Without its touching the shelf. The horn is secured to the bottoni board of the casingby means as fol.

casing 1with a stripfot' felt or other, sounddeadening material 14 under it, and Washers 16 of siinilar material above it, and further there'niay oe similar bushings 17 provided to surround the screws. f

The neck 18 of the renroducer (Fig. 1) telescopes' with the free end of the tonejarm (el, permitting the former to be rotated about the longitudinal axis of said neck into andout of operating position. The curved tone arm hasan even here and swivels horizontally, being supported on a tubular cap 19 on the above described uptnrned neck of the horn (compare 1 and 7)., 20 isJ an upright from this cap having a hearing for the svv'ivel pin E21 that projects axially upward from the tone arm. Y

'22 is a' rubber throat havinpr a circular .iiange 23 anda tubular portion 24 tapering in 'thickness to its month. 25 is a plug fag imanes valve eperat-ing with the bore of this throat and is mounted on the vertically reciproeatory stem 2G, which latter is guided above in a. hole in a cross piece 27 and extends below through a hole 28 in the lower wall of the neck et the horn.

The throat and Valve form a tone and dynamics regulating means, elsewhere pat- The throat is held in nosition by between cnted. screws 9.9 which clamp its flange the cap 19 and the top of the neck t will be noted that the horn is substantially insulated from the casing by the described supporting means shown in detail in Fig. 4, as are also the tone arm and the reproducer, because these are supported on said insulated horn.

30 (Figs, l, 3 and 7") is a Vertizal partition extending upwardly from the shelf G, and 3l is a permanent cover over the. horn part of the casing flush with its upper edge. The lid 32 hinged at its straight edge is co` extensive with the top ofthe entire instrument, and when raised uncovers the lettV hand part of the instrument, thereby giving access to the reproducer and the turntable to adjust and change records.

33 is a folded or doubled over strip ot telt or equivalent vpacking material for the purpose. secured by cleat Si. and screws 35 -in the torno of an edgingaround the mouth ot this Ylett hand part of the casing (compare Figs. 3 and 7).` This felt, as shown in the latter figure, projects above the actual rim of the opening `so as to contact snugly with the lid when closed, and thereby prevent mechanical noise, due to the operation ot the instrument, fromescaping into the room.

Fig. 10 shows a modification of this 'teature, wherein the felt material 3G is mountedv to project from a groove in the lid yand contacts-with a correspondingly placed rigid strip or bead 37 on the other part of the casing of the instrument.

Further, to complete the description of the AeXternals of the instrumen@ 38`is a curved door (Fig. 3) hinged at 39k which, when closed, continues. and completes "the curved front of the instrument. 4l() is a curved, vertically positioned, stationary piece of board leading from the rear edge ol the horn' to the rear et ge ot the door. .lhe legs of the instrument are designated Lil.

l2 is the usual motor winding-handle insertible through a hole in the front ol. the instrument into engagement with the winding stem 43 of the spring motor l, which latter may be of any usual or preferred construction.

Means are provided so that the operator can continuously operate the throat Valve 25 to Vary .the dynamics and the quality ot the tones in sympathetic accord with the record being played; or the operator may move a `pointer over a dial, marked from double piano to double torte, to any desired indien tion which will automatically' adjust 'the aforesaid valve to a correspoinling position relative to the throat, so that the. instrument thereafter will play with the degree o' dynamics indicated on the dial until the pointer is adjusted to a new position, or until the first named means is operated. The con e nation of means by which 'these two in nientalities both act on the saine valve 'wi hout interference with each other will no w be described.

The valve Stem 26, as shown in Fis, i a ud in the enlarged View Fig. 6, projects throi bl. a hole in the bottom of the instrument where 'it connects by a link 4.1L and by a crank arm are .normally spring-held in their lowerniost l position away from the throat, which ne cordingly normally wide open tor loudest playing.

5l and are a pairotl similar wood mounted on either 'side of the aforesaid arm l) but, unlike it, 'they each swingt loosely and independently on the shat #hij rl. connecting rod 53 runs from the tree end of the a rin 51 and a rod 5l from thearcn is a pin extending through the cranlr a 'ai .sllwvith its respectivecends located in the path et these swinging arms 5l and 5:5., which latter, where they contact with the pin, are faced with Ytelt as best shown at e, in Fig. (l: the object being to secure noir lessl operation. rl `he net result ot' the tore going devices is that when the connecting); rod 53 is pulled by intermediate means con nected with the pointer 5G adjustable over the dynamics dial 57, it swings its connected arin 5l into contact with the aforesaid pin 55 and thereupon carries the crank arm with .it against the tension oil the spring and so adjusts the throat valve toward and perhaps into the throat to an extent corre sponding in playing eltect to the indicated adjustment ol" the pointer ou the dial. "lhe intermediate ,connections between said pointer 5G and said connecting rod 5&3 are as tollowse in the first place, the pointer placed v\. iiy.oiit.ally over the dial iii' (see to dan view ot' the instrument Fie'. til.`

whereby said toncarm is insulated :in its entirety by Said horn from Said frame and casing.

2. In a talkingv machine, a horn inclosed within the casing of the machine and secured thereto by intermediate insulation which insnlates the entire horn from Said casing, vsaid horn having an upturned end;

' shelf and casing.

3. In a phonograph, the combination of a casing' comprising a record-playing eompart ment; a-,closnre therefor for the introduc tion of vrecords into playing` position and their removal; son11d-reproducing mechanism, including a diaphragm, disposed within said compartment; a sound-conduit leading from said compartment; and packing means so arranged as to form a Sound-tight joint between said eompartnlent and its closure when the latter is closed, thereby to maratea prevent the escape from said compartment of sounds propagated from the exterior of the diaphragm.

4f.- 'In a talking machine, a playing control-device, a flexible wire control for operating the same from a distance, motor-A hrake means, and a separate Wire in said yflexible control operatively connected wit.;

the motor-brake means. l

5. ln a talkin g machine, a playing controldevice, a fiexihle wire control for operating fit from a distance comprisingv a relatively slidable wire and a surrounding casing therefor, and further comprising a handle comprising two relatively slidable parts attached respectively to said wire and casing parts, motor-brake means, a third movable part on said handle, and another wire in the aforesaid easing whose one end is connected with said third movable part, and whose other end is-operatively connected with said brake means.
