9 Claims.

- My present invention relates to a portable combined automatic phonograph and radio and constitutes an improvement upon the apparatus disclosed in my co-pending application, Serial No. 16,418, filed April 15, 1935.

Primarily my present invention differs from that disclosed in my aforesaid application in that the record receiving means is made as a constituent part of one of the sides of the portable cabinet thereby simplifying the construction without destroying the capability of the record receiving means from operating as a guard for holding the records on the turntable when the instrument is being transported from place to place. With my present construction I am also enabled to play the phonograph while the lid of the cabinet is closed without interfering with the successive automatic discharge of the records on completion of the playing thereof. I am also enabled to make use of a self-contained radio receiving set unit and install it into the portable cabinet with a minimum expenditure of time and effort. The construction and cooperative arrangement of parts are also such as to permit the use of a larger loud speaker and a larger speaker bafile board, thus increasing the tonal qualities of the instrument without increasing the height dimension of the portable cabinet.

My invention will be more iully understood from the detailed description which follows when considered in conjunction with the accompanying drawing, wherein: I

Figure 1 is a perspective view of a portable cabinet in closed condition embodying the combined automatic phonograph and radio of my invention.

Fig. 2 is a perspective view of the cabinet of Fig. 1 with the lid thereof raised and the end wall which constitutes a closure for the front of the radio in open position.

Fig. 3 is a perspective view of the apparatus with the parts in the same respective relation as in Fig. 2 and showing the record receiving tray in its record receiving position.

Referring to the several figures of the drawing wherein the same reference characters are employed to designate the corresponding parts, the numeral l designates a portable substantially rectangular cabinet comprising a body portion consisting of a bottom I I, side walls l2 and I3, end walls I! and I5 and a lid l6 hingedly connected to the end wall M by a piano hinge or the like H. The side walls l2 and I3 and the end wall I5 have their top edges rabbeted to form upstanding ribs or flanges l2, l3 and I5 respectively, which seat within the rabbeted free edges of the depending walls l8 of the lid IS. The end wall l5 which may be considered as the front wall of the cabinet or as the closure wall for the radio receiving set I9 is hingedly connect- 5 ed to the bottom wall II by the fabric covering of the casing or by other suitable means so that said wall when not held in closing relation by the lid of the cabinet will drop down by the action of gravity into open position to render avail- 10 able for adjustment the control dials of the radio and when the cabinet is mounted on a horizontal surface said wall in open position will normally assume the position shownin Figs. 2 and 3 and function as a sounding board or deflector for the sounds issuing from the loud speaker of the radio.

Within the body of the cabinet there is mounted an automatic phonograph of any approved design including a, turntable disposed below the top edges of the body portion of the cabinet hav- 20 ing a central pin 2| adapted to accommodate a plurality of sound records 22 in superposed relation, a tone arm 23 and automatic mechanism comprising a, pivoted arm 24 adapted to successively remove each record from the turntable 25 after it has been played. The specific contruction of the automatic phonograph does not constitute a part of the present invention, but is of the type that comprises an electric motor and operative record discharge mechanism (not shown) which will remove each record in succession after being played by raising said record to clear the top of the pin 2| and giving to it a motion of translation which will discharge it from the turntable. Such automatic phonograph mechanism is shown and described in the patent to Mitchell et al. No. 1,936,335, November 21, 1933. To receive the records 22 when discharged by the automatic mechanism I have provided a record receiving tray 25 which has a fiat bottom 26 of somewhat greater than semi-circular form and an upstanding surrounding wall consisting of a substantially semi-circular portion 21 and a flat portion 28. The flat portion 28 of the wall preferably constitutes a part or a section of the side wall l2 and is hinged to the main section of said side wall by a piano hinge or the like 29 along a line which is parallel to and preferably below the plane of the turntable 20. The record receiving tray 25 may have its upstanding wall portions at their juncture reinforced by triangular reinforcing pieces 30. The tray 25 when in record receiving position e. g., in the position shown in Fig. 3 with the tray extending laterally from the side wall I2 is braced in its horizontal operated in the usual manner.

laterally extending relation to the cabinet by the engagement of the wall 28 with the outer face of the side wall I2. Preferably, the tray 25 is of such dimensions with respect to both area and depth as will adapt it to engage over the group of records 22 on the turntable and extend down into encircling relation to the turntable to constitute a holding and confining means for said records when the hingedly connected side wall section by which said tray is carried is in its normal side wall relation. The bottom of the tray 26 maybe provided with an overhanging lip or projection 26' which when the tray is in turntable encircling position engages over the tone arm 23 to hold said tone arm against accidental movement toward the lid when the cabinet is being carried from place to place.

The phonograph unit of the apparatus is preferably mounted within the rear of the body of the cabinet and the radio receiving set IS in the .front of the cabinet. As herein shown the radio receiving set I 9 is in the form of a self-contained unit which may be mounted within the cabinet with but little expenditure of time and effort. As shown the casing of the radio is of greater height than the side walls and end walls of the cabinet l0, thus permitting of the use of a larger loud speaker unit and a large baffle board for the radio whereby the total qualities thereof may be improved. This increased height of the radio casing, however, does not necessitate any increase in the height dimension of the cabinet, since the projecting portion of the radio casing above the sides of the cabinet seats within the lid of the cabinet. The radio receiving set l9 as is conventional includes an electromagnetic unit provided with a diaphragm (not shown) and electric amplifying means (not shown), and per se constitutes no part of the present invention. It is desirable, however, that the electromagnetic unit of the radio receiving set be so mounted as to direct the sound waves produced therein toward the baflie board 32 so as to impinge upon the end wall l5 so that the latter may function as a sounding board. In order that the advantageous qualities of the electronic amplifying means and the electro magnetic unit of the radio receiving set may-be utilized for reproducing sound from the phonograph records, the tone arm of the phonograph is connected up with the aforementioned means in any well known manner.

When the lid I6 is closed down over the top edges of the end wall 15 and the side walls I 2 and I3 it serves to hold said end wall in closed relation to the cabinet and to hold the record receiving tray 26 in its record confining relation over the turntable. When the lid of the cabinet is closed the cabinet as a whole will have the appearance of a travelling case as shown in Fig. 1 and may be carried from place to place by'the carryinghandle 33 mounted on the side wall I 3 For operation as a radio or an automatic phonograph the lid I6 is first raised and the connecting cord (not shown) for supplying electric current for the phonograph motor and the radio receiving set is plugged into an electric socket or outlet. If the device is to beused as an automatic phonograph the receiving tray 25 is brought into record receiving position by being turned about its hinge 29 and the phonograph The tray 25 in its record receiving position being below the bottom of the turntable it will be appreciated that as the records are discharged from the turntable they will be gracefully slid into said tray. In View of the tray construction, e. g. with one wall thereof formed as a section of the side wall l2, itwill be appreciated that an opening will be provided in the side wall l2 through which the records may be successively discharged upon the completion 5 of the playing thereof, even though the lid 18 be closed down upon the topedges' of the body of the cabinet. The radio may be operated when the tray 26 is in its record receiving position or in its record confining position with either the lid -of the cabinet open or closed.

Although'I have shown and described a preferred embodiment of my invention I do not wish to be limited to the precise details of construction disclosed since-changes may be made therein within the realm' of mechanical skill without departing from the spirit of the invention as claimed. 7
