Patented Feb. 24, 1931 UNITED STATES PATENT OFFICE LOUIS SEUTTER, OF MILWAUKEE, WISCONSIN, ASSIGNOR TO THE KIEL FURNITURE COMPANY, OF MILWAUKEE, WISCONSIN, A CORPORATION OF WISCONSIN RADIOTABLE Application filed August 1,

This invention relates to improvements in radio tables.

It is one of the objects of this invention to provide a radio table, in which a complete radio apparatus and speaker may be so concealed that the table will have the appearance of being an ordinary occasional table and in which, in spite of the concealed position of the speaker, the sound vibrations will be permitted to come forth therefrom '111 such a manner as to give true tone value.

A further object of this invention is to provide a radio table in which means is provided for deflecting the sound vibrations emitted from the rear of the speaker so that said vibrations will not interfere with or neutralize: the vibrations coming from the front of the speaker to impair the tone value.

A more specific object of this invention is to provide an improved radio table in which the apparatus and speaker are mounted upon a novel type of baflie board, the said baffle board having a fence surrounding a portion thereof, the said fence decreasing in height toward the sides to direct the sound vibrations emitted from the rear of the speaker toward openings provided beneath the table top, on each side of said bafile board.

A further object of this invention is to provide a radio table in which resilient feet are provided on which the receiver is adapted to be mounted, the said resilient feet preventing vibrations from the speaker from impairing the operation of the receiver and vice versa, and said feet further being adapted to elevate the receiver so that a portion of the speaker may extend therebeneath, the latter feature permitting a more compact construction. 1 I

A further object of this invention is to provide a radiotable in which an opening is provided between the table frame and the top to permit sound vibrations to emerge therefrom, and also to permit a complete circulation of air beneath the table to carry away heat generated by the receiver.

A further ob ect of this invention is to provide a radio table which is simple in construction, attractive in appearance, and well adapted for the purpose described.

. to carry away heat from thefreceiver.

With the above and other objects in view, the invention consists of the improved radio table, and all its parts and combinations, as set forth in the claims, and all equivalents thereof. I

In the accompanying drawings, in whlch the same reference characters designate the same parts in all of the views:

Fig. 1 is a perspective view of the 1mproved table, the front panel belng swung downwardly to permit access to the operating knobs;

Fig. 2 is a top view of the table, wlth the greater part of the table top removed to show interior construction;

Fig. 3 is a vertical longitudinal sectional view taken on line'33 of Fig. 2;

Fig. 4 is a vertical transverse sectional view taken on line 44 of Fig. 2, parts being broken away; and 70 Fig. 5 is an enlarged fragmentary detall view showing the means for providing an opening between the table frame and top.

Referring to the drawings, the numeral 8 designates a table top, 9 the body or compartment portion which is formed in part of side panels 10, 11 the suporting legs, and 12 the stretcher or lower brace member which conmeets the lower portions of the legs together, The table may be of any desired shape, and in the form shown, the legs extend upwardly to the top and the side panels are interposed therebetween, and with the exception of the front panel 10, arerigidly connected to the le Serial No. 382,751.

vided with one or more depending fast Ding" members 14 which are adapted tofit'wlthin clip members 15 (see Fig. 5) when thezltop 96 is closed to hold the top slightly above the table frame. This provides a space 16 through which sound vibrations may come forth, and through which air-may circulate creases toward the sides as at 23 (see Figs.

3 and 4) The receiver 24 is adapted to be mounted on resilient legs 25, constructed preferably of rubber and carried by the baflle board. Spacer blocks 26, extending inwardly from the ends of the fence are adapted to engage the sides of the receiver to position the same. Other spacer blocks 27 are positioned adjacent an opening 28 for the loud speaker 29. When the receiver is in position on the supporting legs 25, its rear portion fits agalnst the spacer blocks 27 as shown by the dotted lines in Fig. 4, and. the set being elevated by the legs, overlaps the flanged portion of the speaker as at 30. This permits a very compact construction.

The front panel 10 is hinged to the front lower edge of the baflle board 19 or to any other desirable portion of the frame, to permit it to swing downwardly to open horizontal position as shown. A supporting arm 31 engaging the panel and the body of the table supports said panel when in open position. Behind the panel 10 is an inner panel 32 which is formed with an opening 33 for exposing the controls and dial of the receiver.

It will be noted from Fig. 2 that large openings 34: are provided between the partitions 18 and the side panels 10. Smaller openings 35 are provided on the outer side of the fence 21, and other openings 36 are provided between the sides of the baflie board and the partitions near the front of the table.

. It is also to be noted that the loud speaker is so carried by the bafile board that the sound vibrations will be directed downwardly by the speaker toward the floor from the proper height 'to assure true tone value. If the speaker were supported too close to thefloor, the tone would be distorted, and if it were positioned too far away the beneficial results caused by directing the vibrations toward the floor would be lost. When the radio is being operated, the majority of sound vibrations are emitted from the front of the speaker and said vibrations are directed downwardly through the opening 28. However, other vibrations come forth from the rear of the speaker, and' it is found that in ordinary radio cabinets said vibrations frequently meet the vibrations coming from the front and interfere with or neutralize the latter, thereby impairing the tone quality. Inthis improved radio table, however, the vibrations emitted by the rear of the speaker are separated by the bafile board '19 from the vibrations emitted by thefront of the speaker. By employing the improved bafile board with the fence 21, the sound vibrations coming from the rear of the speaker are caused to travel over a comparatively long path before emerging, and therefore they will not cause interference. The major ity of said sound vibrations will travel over the low side portions 23 of the fence, through the recesses 18 of the partitions 17 and out through the large openings 34 between the partitions and the side panels 10. Other of the sound vibrations emitted from the rear of th'e speaker will pass over the high portion of the fence 21 and out through the openings 35. Still other vibrations will travel out through the openings 36 and through the opening 16 between the top and the table frame. Thus all of the vibrations coming from the rear of the speaker will be forced to travel over a comparatively long path and as a result there will be no inter-, ference with the sound vibrations emitted by the front of the speaker and a tone of exceptional quality and volume will result.

It will readily be seen that the elevation of the receiver by the resilient legs 25, in addition to permitting the overlapping of the edge of the speaker, prevents vibrations caused by the speaker from impairing the operation of the set. It will further be seen that by'having the top 8 spaced from the frame to provide the opening 16, a complete circulation of'air from the bottom to the top of the compartment 9 is permitted, to carry away heat from the receiver tubes.
