PORTABLE CASING FOB. TALKING MACHINES.

Application filed November 8,1821. Serial No. 512,587.

of Great Britain and Ireland, residing at 741 High Road, Leytonstone, in the county of London, England, have invented certain new and useful Im rovements in and Relating to Portable asin for Talking Machines, of which the fol owing is a specification. I

'This invention relates to gramophones and the like, and is intended for application primaril to portable gramophones mounted in folda 10 cases. The invention has for chief objects to enable the gramophone and case to be folded into smaller compas than heretofore, and to provide an improved construction of combined horn and sound diifuser or reflector.

In carrying out this invention, I hinge the motor-box and the diffuser or reflector to the case in such a manner that in order to close the case the reflector is first swung outwards, the motor-box is then swung inwards so as to bring the turntable close up against the back of the case, the tone-arm is next swung underneath the sound difl'user or reflector, and the latter is then folded back into the case so that the tone arm and a ortion of the turntable are accommodated 1n a space behind the reflector.

The horn passes through one side or portion of the sound difiuser or reflector, being conveniently and, if desired, permanently fixed thereto by means of a flange with which it may be provided. The horn is arranged so as to deliver the sound waves into the inner" end of the sound difl'user or reflector. The tone-arm has its inner end swivelled to the open end of the horn.

In the drawings Fig. 1 is a front elevation showing the case open and, in full lines, the motor-box andtone arm folded outwards in the position for playing.

Fig. 2 shows the motor-box and tone-arm in side elevation and the reflector and rear portion of the case in vertical section.

Referrin to the drawings, the motor box a is hinged at its lower rear edge a to the lower front edge of the case b and it is also made of such width from back to front that its top and the turntable a overhang it at the front to form a recess which, when the case is closed, is occupied by the tone-arm,

- the sound-box and. the turntable. Its front portion may be provided with rubber or like bufl'ers (not shown) on which it rests when opened out from the case.

When the motor box is folded outwards, its base a forms a continuation of the lower end of the case b and it may be maintained against accidental displacement from that position by means of a spring catch or the like which is fixed to the motor-box and engages the adjacent side of the case.

The sound diffuser or reflector d is hinged at d to the top front edge of the case and its shape is preferabl substantially frustropyramidal so that it ts snugly into the ease.

The inner end of the soun diffuser or reflector terminates in a yramid (3 whose apex is directed outwardly.

The portion of the case above the motorbox is provided at each side with a vertical door I) hinged thereto and extending, when closed, approximately halfway acrow the case.

Dealin now with the combined horn and sound di user or reflector, the horn e passes through the lower portion of the sound diffuser or reflector and is fixed thereto by means of a flange c with which it is provided. The portion of the horn on the underside of the sound diffuser or reflector is swivelled at e to the upper end of the tone arm f so that the latter can move sideways vas the needle g, carried by the reproducer, travels, in the usual wa over the record It.

The sound waves from t e upper open end'of the hornimpinge on the pyramid d, and are deflected thereby forwards.

It will be obvious that the horn may be combined with the sound diffuser or reflector in various other ways. For example, it me be attached to the underside of the soun 'difl'user or reflector and be bent or otherwise shaped so as to extend around the front edge of the sound diflfuser or reflector; this ar rangement renders any cutting away. of the sound difi'user or reflector unnecessary. Or again, the horn may be let into a recess or slot formed in the front edge of the sound difi'user or reflector. The point at which the horn passes throu h or around the front edge of the sound dlfi'user or reflector may be The sound difluser or reflector is prevented from becoming accidentally displaced from its inner position by means of spring catches d or the like. I

Rotatably mounted on a pin a, project-- ing below the overhangin top of the motor-- box, is a needle tray a, w ich can be swung outwards for the supply of needles. When not in use, the tray is swung inwards into the position shown in Fig. 2 in which position the overhanging portion of the motor box constitutes a lid for the needle tray.

In order to fold up the gramophone and case, the needle-tray is first swung in underneath the motor-board and then the winding-handle a is placed in a spring-clip (1 provided at the front of the motor-box, as

shown in Fig. 1, and the sound diffuser or reflector d is drawn outwards into some such position as that shown in broken lines in Fig. 2, so as to provide clearance for the motor-box. The tone-arm is next swung backwards behind the lower sloping portion of the sound difl'user or reflector, and the sound-box and'swan-neck are folded back thereon. The tone-arm is then drawn for- .wards a little and is held in the position shown in broken lines by means of a sprin catch d or the like, which 'is fixed to t e sound difi'user or reflector and engages the swan-neck. The motor-box is now swung upwards and inwards into the position shown in broken lines in Fig. 2, and the sound difl'user or reflector, tone-arm, etc.,

are swung downwards and inwards, as illustrated, and are held in' that position by meansof the catches d. It will be seen from an inspection of Fig. 2 that the triangular space behind the lower portion of the sound diffuser or reflector is now occupied by theoverhanging portion of the motor-board and turntable, md also by the tone-arm, etc.,

which arrangement results inconsiderable economy of space and compactness of construction. v

In its closed position, the base a of the motor box closes the lower ortion of the case. The. doors 6 are now 0 osed, one after the other, one of them being provided with a rabbet into which the other one fits, and the lower edges of both doors fitting into a rabbet a" .provided in the motor box.

. Finally, a catch 6 is turned down over the top edge of the doors. Thus, by means of the The arrangement of combined horn and sound diffuser or reflector is applicable for use with other gramophones and, the like besides the foldable gramophone above described.

It is to be understood that the swivellin of the horn to the tone arm may, if desire be eflected within instead of below the sound diffuser or reflector, also that the flange a may be arranged below instead of inside the sound diffuser or reflector.

I claim 1. A gramophone-cabinet comprising a casing, a motor-box hinged at its lower rear edge to the lower front edge of said casing, a sound difl'user or reflector hinged to said casing, and a bin ed tone-arm, the parts being so arranged t at, in their open position the bottom of the motor-box is flush with the bottom of said casing, and in their closed osition the motor-box lies completely within the casing, and thetone-arm lies between.

the motor-box and the sound difi'user or reflector.

4. In a portable casing for sound reproducing machines, comprising a receptacle which is open at its front when in use, a sound diffuser connected to the casing in such a manner as to be capable of swinging outward therefrom, a reproducer tone arm and horn associated with and maintained by the sound difiuser, the parts being so connected that the sound reproduoer may be moved to 1 motor box which maintains a turntable, said be, ositioned partly in the rear of the sound di user when it is moved outward, and a motor box being connected with the receptacle to be moved Within the same.

5. In a device of the character described, a casing having pivoted thereto a sound diffuser which is adapted to be swung beyond the open side of the casing, a horn fixedly attached to the sound difiuser, an arm movably connected to the horn and adapted to be extended beyond the sound difi'user, a reproducer pivoted to the arm, a motor box and turntable support hinged to the lower forward portion of the casing said box being and adapted to form a artial closure for the casing, doors hinge to the casing to complete the closure therefor when the parts herein mentioned are positioned within said casing. r
