@ww/MM ATTORNEYJ y Patented Dec. 22, v1931 UNITED s'ra'rlizs NAOJIRO YAMANAKA, F KANAGrAWA-KEN','J'.AItAN` TALKING MACHINE Application led January 8, 1930, Serial No. 419,366, and in Japan January 31, 1929.
This invention relates to improvements in talking machines and more particularly to an improved cabinet thereof so constructed that it may provide a relatively large tone chamber of the horn type and has for its object to provide a construction of cabinet to cause the talking machine of small type and especially portable type to reproduce rela tively loud and clear sound. 1
In the accompanying drawings:
Fig. 1 is a perspective view of the talking machine. 4
Fig. 2 is the similar view to Fig. 1, but the top and bottom cover being opened.
Fig. 3 is a vertical section on the line III-III of Fig. 2, but the top cover being closed.
Fig. 4 is a cross -section on the line IV-IV of Fig. 3.'
y Referring to the drawings, the cabinet is indicated as a whole' by "the numeral 1, in
which a talking machine of vwell -known typemay be installed in the usual manner, the tone arm, sound box, turntable and driving 4motor being indicated by the numerals 2, 3, 4 andV 5 respectively.
The cabinet 1 comprisesl an ordinary hinged top cover 6, a body 7 and a bottom cover 8 swingably connected at 9, 9 to the lower end of the side walls of said body as shown. The body 7 is substantially of a three-sidedl square box having a s ecial raised `bottom n10, the front side-wall `eing partly omitted, and is provided with a suit'-l tone arm 2 and the underside of the raised bottom 10 to form a part of the sound amphfying horn as indicated by the numeral 11 by way of example in Figs. 3 and 4. The front part of the raised bottom 10 is upwards curved towards the front end as shown so that it form -the sound amplifying horn having the suitably increasing cross sectional area toward the front end. l y
The bottom cover 8 comprises two side walls 12, 12,.each having the increasing height towards the front end and adapted to make sliding fit with the corresponding slide wall 5o of the body, a bottom wall 13 and a front able conduit'betweenthe lower end of the wall 14 connected at its lower end to' the front end of said bottom wall 13 by means of the hinge 15, which may be suitably curved or flat and carries two wing walls 16, 16 adapted to make sliding fit with the corresponding side wall 12. In closed position, the bottom cover 8 is held in position by any lsuitable means such as the holding piece 1,7 co-operating with the slot 18 at the front wall 14 of the bottom cover as shown in Fig. 1. In opened position, the said bottom cover is held positioned by any suitable means such as a screw 19 having a winged thumb piece, the screw being threadable through the side wall 12, into a cavity (not shown) in the body 7 whilst the front wall is held opened by any suitable holding means such as the screw 20 adapted to engage the groove 21 on the side walls 12, the side walls 12 and the wing walls 16 being arranged partly to overlap the cor- 70 responding side wall of the body and said side wall 1l respectively, so that, as shown in Figs.`2 and 3, these walls combined with the raised bottom form a complete and tir-tight wall of the sound amplifying horn having suitably increasing cross sectional area to# wards the front open end. The mouth or exit area of the horn can be made quite large, combined with the sizeof the cabinet. The supports 22 are detachably attached to the body 30 by suitable means such as screw. The arrangement of the front wall 14 with wing walls of the bottom coverI may beomitted,v if desired. In practical construction,'the side walls of the bottom cover can be made so as .85 to make sliding fit withlthe inside of the side walls of the body, without departing from the scope of theinvention.
Having now particularly described and ascertained the nature of my said invention and in what manner .the same is to be performed I claim :l
1. In a talking machine, a cabinet compris. ing a raised bottom of suitable curvature and a bottom cover having two side walls adapted to make sliding t with corresponding side walls of the body and swingably'connected near the rear end of the body so that, when it v is swung open, these bottom cover and side walls combined with the raised bottom form a complete and air-tight wall of a part of the sound amplifying horn having suitably increasing cross sectional area towards the front open end Jf the cabinet. 5 2. In a talkin g machine, a cabinet comprising a raised bfttom cover having two side walls adapted to make sliding t with' the corresponding side walls of the body and swingably connected near the rear endlof the body and having the front walk hinged at the front end, with wing walls adapted to make sliding fit with the correspondingl walls of the bottom cover, so that, when the bottom cover` and the front wall are swung open, these walls combined with the raised bottom form a complete and air-tight wall of a part of the sound amplifying horn,y having suitably increasing cross sectional area towards the front open end of the cabinet.
