Patented Dec. 1,1936 l UNITED STATES PATENT} OFFICE RADIO RECEIVING SET Leon 1!. Amdur, Brooklyn, N. Y., assignor to Masterpiece Radio Cor-1)., Brooklyn, N. Y., a corporation of New York Application January a7, less, Serial No. 50,932

'1 Claims- (Cl. 250-14) This invention relates to radio receiving sets and more particularly to cabinets and the general arrangement thereof with special reference to the cabinet in which the set is incorporated. One

' 5 of the objects of this invention is to devise a radio receiving set which shall occupy very little space and which shall be usable without occupying floor space and without the need of special furniture, such as a standard or end table, upon which to place it. This object of the invention is especially important in such instances as hotelrooms, where there is very little space to spare,

although it is not necessary, in the contemplation of this invention, that the set be limited in use where space must be conserved.

Another object of this invention is to devise a radio set and ,cabinet therefor, which in addition to the first object above mentioned, shallbe more suitable and convenient for manipulation than radio sets heretofore made. In the present sets;

be it a cabinet or console model or a small table model, to manipulate the controls, an adult person must bend to reach them and bend still further to read the station dial. That is, this 5 object is to devise a set which shall be placed at the correct height for facility, ease and convenience in adjusting the controls and reading the dials. Closely connected with this object, a further object is to devise a radio receiving set in which the set and/or the loud speaker unit thereof shall be at the correct height for audibility; this height is, for the best audibility, at the level of the ear of adult persons.

To attain the above objects and other objects 5' below mentioned and such'other objects as may hereinafter appear, I make my radio receiving set in the form of .a picture to be hung on the wall, either from the picture molding of the room without stooping) andthe ears (in listening to the reception especially in the act'of adjusting the set). Furthermore, because of the coordination of the three senses mentioned and because of the fact, that in devising the set as above set .forth, the conditions are made 'ideal for all three requirements, the maximum enjoyment will be attained in radio reception. From the standpoint 55 of the ear. the loud speaker unit of the receiving set may itself alone be framed and hung as a picture. I, In so malrlng the the receiver that it may be hung on the wall, no limitation is set upon the height at which it may be placed (as in cabinet 5 and table models); the receiver may be located where it will best suit all conditions above enu-. merated, which as mentioned, is at the ear-eye level. An additional advantage attained thereby is that better resonance may be gotten from the 10 wall sincethe set may be locatednearer the center of the wall, i. e. its point of vibration, and closer to the wall than in present sets.

In addition to attaining the above-objects andadvantages, my invention contemplates theemreceiving set of this invention itself serves as 2 another piece, namely, a picture. Another advantage and object is the facility with which" wiring connections (aerial, ground, current) may be made, both from the standpoint of distance and location and also for blending or camouflag- 5 mg the wire connections.

Another .aspect of this invention contemplates the association of the various controls of the 'receiving set (which are, at least, the switch,

the station dial and the volume knob, but which may include other controls and adjustments) with, and in, the particular picture shown. That is, in this aspect of the invention, the controls will not appear as such, but will becamouflaged aspart of the picture, so that the uninitiated them. This aspect of my invention is not limited to radio receiving sets which arein the form of a hung picture, but may be embodied in the front face or panel of either console and cabinet models or small table sets. In addition to the controls bein formed as part of, or blended into, eloiid speaker unit will be formed the picture,

and disguised in the same manner. Besides, the

set may be provided with a light or lights, also disguised as part of the picture, which will be lit to illuminate, for example-thestationdifl.

Other objects of the invention is the construc- 5 tion of parts and. arrangement thereof so that the set may be brought within the encompass of a picture (of small size, preferably) both from the standpoint of width and height and also to be positionable within 'a shallow casing, as a pic- '55 ture must be. -Another object is to so locate the parts and so construct them as part of the picture, as to take advantage of certain features and limitations set by the physical requirements of pictures.

For the attainment of these objects and of such other objects as may hereinafter appear or be pointed out, I have illustrated an embodiment of my invention in the drawings, wherein:

Fig. l is a front view of the set in position on the wall and suspended from the picture molding.

Fig. la is a detail of the picture and service wires.

the susshowing movable parts thereof foradjusting the the above two arrangements, the suspender may set.

Fig. 3a is a detail (side elevation) of the movable part which adjusts the station selector.

One form of my improved radio receiving set is shown in Figs. 1 and 2, wherein the casing for the radio receiving elements is designated 8 and the picture frame, for the four sides, designated la, lb, lo, and Id, and the picture is designated 2. The set is shown suspended from the picture molding of the room by the picture wire 4, which may be secured to the frame sides lb and Id, as

shown, or to thesides of the casing. The picture wire may be looped over the usual'molding hook (not shown), or the picture wire may be secured'to the suspender 5 at la and 4b. The suspender has a hook end 5a which fits oven the picture'molding 3.

The suspender may have a number of binding posts, four being shown, 5a, 51 52, and 510 for the aerial wire, the ground wire and the current wires. Where the binding posts are located on the suspender, the respective wires are run along the picture wire 4, to the set; the wires, 2: and :z:' for example, insulated from each other andfrom the picture wire 4, may be encased'in an outer braid 40, Fig. 1a. The aerial, ground or current wires inbeing brought to the connection 5, would be concealed by the picture molding, see wire 2, Fig. 2 Instead of locating the binding posts, or all of them, on the suspender 5, all or some may be located on the frame itself, see it, Fig. 2', at convenient points thereon; also, additional binding posts may be there provided. This is for convenience inconnecting the set to the respective wire, which are usually brought from various points in the room. Instead of approaching the set from above, the wires or some of them may approach the set from the fioor.

Instead of placing the suspender on the picture molding, the suspender may be provided with a nail hole or holes, such as 6, Fig. 2a, for securing the suspender to-the wall at levels lower than the picture molding, if. desired. In addition to be made to be concealed behind the picture; in this case no picture wire is used. The set is made to befastened directly to the suspender; this is shown in Figs. 2b and 2c. The suspender 5 is first secured to the wall, by nails or other-means; the set is then attached to thesuspender by any suitable means, such as the modified bayonet joint shown in the figures. The rear wall I of the casing of the set is provided with the bayonet sIot comprising an enlarged portion la and a narrow portion lb. The suspender is made of a size to snugly fit in the enlarged slot, but not in the narrow portion. At both sides of the suspender is provided a groove, 5L (left) and 5R. (right), such that the material of the suspender between the grooves, ,designated X in Fig. 2c, is just a little narrower than the narrow portion lb of the bayonet slot. Hence, when the suspender is fully fitted in the enlarged portion la of the bayonet slot, the set may be lowered with the narrow slot lb, or rather the side edge thereof, fitting in the side grooves 5L and 5B. When the suspender is used in this manner, the aerial, ground and current wires are run directly to binding posts on the set, rather than on the suspender.

The picture frame the picture (2, Fig. 2) is as near the outside edge of the frame as possible; that is, the picture is very little set-in in the frame. The reason for this is to provide as much space as possible for the casing 8 of the receiving set. The front of the casing is the frame and picture 2; the rear wall 1 forms the rear face. Pictures are usually hung so as to be inclined to the wall; in embodying this invention, advantage is taken of this fact to secure sufficient space behind the picture for the casing, which appears as a trapezoid, see Fig. 2.

The receiving .element which requires the great est width may be either the loud speaker unit, or the variable condenser unit or both which would be placed, in the trapezoidal casing nearest the top of the picture, 8t, Fig. 2.

Within the casing 8 is housed the receiving set. The loud speaker unit might be directed toward the front of the casing, i. e. the-side covered. by the picture, which would be painted or otherwise impressed upon a loosely woven fabric, so that the egress of the sound waves will not be hindered. The opening of the speaker unit may be directed, instead, to other sides of the casing, for example,

is made so that the plane of the top side, 8t, Fig. 2, which would be provided with theappropriate opening or openings thereof; this arrangement would be used, for instance, where it is desired to cover the picture with glass.

The radio'controls (station dial, volume control, switch, etc.) may be located on the frame, on the casing, or formed as part of the picture. In the form shown in Figs. 1 and 2, the station selector, 9a, the station, dial 9b, and the volume control, 90, are on the frame, and the switch 9:1 is on the side wall of the casing, see Fig. 2. The controls 81: and 9c may be on the casing; the switch 9d may be on the frame, etc.

Where an indoor-aerial or a loop aerial is used, this may be formed by looping wires, such as In, around the casing, so that they are hidden by the top edges of the frame, see Fig. 2; or, the picture wire may constitute an aerial or part thereof.

In Figs. 1 and 2, the controls are on either the frame or the casing or both. Another aspect of this invention contemplates the disguising of the controls in a picture of which they form part. In this aspect of the invention, the picture may be a hung (and framed) picture or it may be on the panel of the ordinary radio receiving set, either the floor (cabinet .or console) or the table model. An exemplification of this aspect'of the invention appears in Fig. 3 which represents a portion of a.

2,062,632 from the loud speaker unit behind the picture,

designated l2). Any kind of picture or painting may, of course, be shown; it should, though, de-

pict parts which are susceptible of relative mo-' to amplify, or at least, not hamper, the sound production therefrom. For these reasons the picture, at points, may be attached to either stationary or vibrating parts of the speaker.

In addition to the securement of the picture to the frame, a number of cross-pieces, i3a, I3b and others not shown, which are used for purposes soon to be explained, may serve to hold the picture in place. These cross-pieces, besides securing the picture also serve to support the movable parts of the picture, which parts, as above stated, adjust the receiving set. For example, in the bar-room scene selected as an illustration, a stein or bottle d might repose on the bar a. and be movable therealong. The stein, which would be formed of, or painted on, a piece of thin wood or thick cardboard or other suitable material, see Fig. 3a, (and which may be either two-dimensional or three-dimensional) is integral with a bridge-piece l4 slidably-held in a slot I3A provided in the cross-piece i 3a. The bridge-piece is stabilized by the movable part (the stein) which be noticeable. The edges of the slot in the pic ture are secured to the cross-piece I3a, see Fig. 3a.

To the bridge-piece M (or its inner member Na) is connected the movable member of the station selector (not shown) of the radio receiving set. By advancing the movable picture part (the stein) along the bar, the selection of stations may be made. The station dial may be painted directly on the picture (e. g., on the hard of the picture) or an illuminable station dial maybe provided as shown. A portion of the picture (as shown, along the bar) designated l5 in Figs. 3 and 3a, is cut out of the picture material, and across this opening is placed a transparent or translucent station dial i512, bearing station indicla l5b. Ailight i5c, seated on cross-piece I30, is lit up (upon operating the starting switch, 9d, Fig. 2) to illuminate the dial. Cooperative with the markings on the dial is an indicator Mb attached to the bridge piece M or its inner member Ma. Thematerial and color of the dial should be such, in relation to the color of the picture, as not to be noticeable; i. e.,

it should not be seen (except, of course, upon close inspection) that there is a dial (on the bar) until the dial is lit up. Upon operating the station selector (the stein) the'indicator idb will be readable coordinately with the markings i5b of the 3 ible through a stationary window. Whatever type of selector dial is used, the movable parts thereof should harmonize-with, and become part of the picture.

The volume control may be concealed, in the bar room scene selected merely for purposes of illustration, by the barrel b. The end of the barrel, shown in Fig. 3, is a piece of suitable material fixed to the spindle i1, rotatably held in a journal I3B in the cross-piece I31). By turning the barrel, the volume of the radio reproduction may be controlled by the I claim: 1.
