TALKING-MACHINE.

Toflll whom "it may concern;

Be it known that 1, James A. RABBITL, a

following is a specification.

invention relates to ,ta llrmgmachlnes and is directed to"the,.prov1s1on of a machinewhich is exceedingly light-and the,

parts of which ;may.'be conveniently and compactly arranged within a suitable cas- -ing,--so that the machine :may ,bc readily carried by .hand, from place to place.

" to, the :bed-y portion of the casing, this My ,improved machii-1e.-,pre'ferabl y comprises va casmg, one side of which is hinged hinged 'side having an opening therein adapted to receive the end of an amplifyinghorn to support the latter. \Vhen the machine is not n use, this openingis-closed by ..a circular metallic plate, and this plate forms the turntable for receiving the disk sound-record; The amplifying-berm may be made'sufliciently shallow to fit within the relatively small casing of the machine, or, if desired, a collapsible horn of :ample size may "be employedwhich can be fo ded so as to occupy but little space. I have illustrated the preferred embodiment of my invention'in the accompanying drawings, m whichp re 1 is a top view of the machine, broken away in part; Fig. 2 is a perspective view, showing the casing closed; Fig. 3 .-is a side elevation, partly in section; Fig.- 4. is a diront View, partly in section; Fig. 5 is a top View, broken away in part, illustrating a modification; and Fig. 6 is a side vi w,

broken away in part, showing the construction illustrated inFig. 5.

Referring first to Figs. 1 to 4, the casing for the machine consists of a body portion 1 and a top 2 hinged at 3 to .the body portion 1. In the removable side 2 of the casing is a circular opening, and this opening is closed by -.a circular metallic plate 4 secured to the removable side .2 in any suitable manner. Within the body portion of :the casing 1, is mounted a suita'ble spring-motor having a w-indable spring within the barrel 5, operating through gearing 6 to rotate a specification ofletters Patent?

central shaft 7. This shatt has a threaded opening therein adapted -to I-reoeive "the threaded endof ashort shaft 8. When the machine is in use, the ,plate 4:1lS'SQCI1I'9d upon the upper end of-t-heshort shaft :8, :as shown in Fig. 4, and receives thedisk-sound-reoond 9. The :body portion 1 of the c'asing-ofdihe machine may have an inner coverplate 10 secured ;ther'eto, -coyering' the 'motorb andhaving .an opening in it through which the windmg-shaft of the motorextends. Secured-Etc this 'coverwplate 10 at one :corner of :the casing is :a tubular member '11, upon which is pivotally mounted a tapering tone- I arm 12 having its larger -end 'turnedadownwardly and entering the-member .111, 510 the smaller .end of .this tonearm is secured a sound-b02113 having its stylus 14 adapted to track in the ,groove of :the' record :npon the inim table it, The tonemmn 12 adaptedfto' :tur'n relatively 'to the-tubular member lfl about 41 vertical :axis, .or iii tdsii ed the connec ion of the tone-arm 1.24m -the. :tubular member .11 may be such. that the ito nearm can turn freely about both werticagl and horizontal axes. The tubular member'ill is extended a'long one side of the casing 1 from the corner thereof where the tone-arm is monnted to the adjacent corner, as indicatedby the dotted lines in Fig. 1, and at this corner it .is turned upwardly .and lpasses again through :the ,plate 10, as shown at 15. The 15 of this tubular sound-conveying passageway is adapted to receive one end of a tubular coupling 16 which connects with a sound-amplifying device. In the drawings I have shown the coupling 16 as a short tube connected at one end to the end 15 of the sound-conveying passageway and at the other end to a shallow amplifying-horn 17.

' This amplifying-horn. preferably has the form/of .a metallic pan with its larger end 7 received in the opening in the removable side 2 of-the casing, the latter forming a support :for-the horn 17. In the side of the horn isan opening, formed to facilitate 'connecti the tubular member 16 to the horn 1. 1

It will be seen that the major portion of the mechanism of the spring-motor is arranged within the casing beyond the peripheryio-f the turmftablee, and that the connectionfrom this portion of the motor mech bottom of the casing. For this reason,-

when the turn-table 4 is removed from the shaft- 8, ample space remains for the reception of the shallow horn 17, by placing the horn in an inverted position over the shaft -8. If desired, however, the short shaft 8 may be readily disconnected from the shaft 7, and in this way even greater space is provided. The joints connecting the tubular member 16 and the tone-arm 12 with the sound-conveying passageway 11 and the joint between the tubular member 16 and the horn 17 are such that these parts may be readily disconnected, and they may be arranged within the casing 1, in the space therein beyond the periphery of the turntable. Preferably the sound-box is so arranged that it may be disconnected from the tone-arm l2, and supporting devices may be provided within the casing of the machine to hold these more delicate parts and thus avoid injury thereto whiletransportingthe machine.

Referring to Figs. 5 and 6, I have shown a somewhat different construction, whereby the same results are obtained and an amphfyFug-horn of ve' much greater size may be used. In this orm of my' invention, the amplifyinghorn f consists of a collapsible horn, one end of which enters the opening in the removable side of the casing, so that the horn is supported thereby. In this form of my invention, the sound-conveying assageway 20 ithin the casing of the'rnac ine extends "fl-0rd the tone-arm 12 along the side of the opposite that to which the removable cover 2 is hinged, to a point at about ,the middle of that side, where it is turned upwardly and passes through the innet cover-plate 10 of the machine. A col-. lapsible horn is shown at 21, consisting of a plurality of sections which when extended form a tapering horn of the form shown, This horn at one end connects with the upwardly turnedend of the tubular, soundconveying passageway 20, and at its other end enters the opening in the hinged coverplate 52. In this form of my invention, I

. have shown the spring-motor as somewhat diiiercntly arranged, the connection from the motor to the shaft of the turn-table being formed by a shaft 22. This shaft, however, arranged at the bottom of the easing of the machine, so that when the turntable is removed from its shaft ample space provided for the reception of the horn 21 when the latter is in its collapsed condition.

ftiaving now described my invention, what I claim as new therein and desire to secure by Letters Patent is as follows i. A portable talking-machine comprising the combination of a motor-box having 21 body and a top which is hinged to the body and which has an opening therethrough, a motor mounted within the box, a turn-table detachably mounted on a shaft of the motor and adapted to be secured to said top in position to close said opening therethrough, an amplifying device adapted to he in moperative position within the box, means for removably supporting the amplifyir. device in operative position upon the b0 y of the box and upon said hinged top in which position it directs sound through said opening in the top, and sound-reproducing mechamsm adapted to be connected to said-amplifying device, substantially as set forth.
