Application August 14, 1935, Serial No. 36,233
11 Claims.
This invention relates to radio cabinets, the object being to provide a cabinet structure, including a radio receiving set and loud speaker, that is mounted upon a trunnion permitting the same to be tilted to varying degrees relative to the vertical to provide for emanation of sound waves horizontally or at varying angles to the horizontal.
' It is further an object and feature of the invention to provide a radio cabinet including a loud speaker mounted on trunnions with the speaker arranged to project sounds outwardly from the cabinet and a sound or baflle board pivoted to the cabinet and, through the turning of the cabinet the trunnions, to vary the angle of the board relative to the speaker and thereby provide for reflection of sound waves at varying angles to the horizontal.
Itis further an object of the invention to 00 provide a new and unique frame construction providing for a trunnion support of the cabinet.
,These and other objects and various novel features of the invention are hereinafter more fully described and. claimed, and the preferred form of construction of a radio cabinet embodying my invention is shown in the accompanying drawing in which- Fig. 1 is a front elevation partly in section showing one form of my trunnion mounted cablnet.
Fig. 2 is a side elevation thereof partly in section.
Fig. 3 is an enlarged section taken on line 33 of Fig. 2.
Fig. 4 is an enlarged section taken on line 4-4 of Fig. 2.
Fig. 5 is a side elevation of a trunnion mounted cabinet of different construction.
The radio cabinet shown in Figs. 1 and 2 consists of a cabinet proper formed of the peripheral side walls I, the top wall 2 and within the cabinet is the radio set indicated at 3 carried on a frame element 4 supported by the walls I. The open bottom end of the cabinet has an inner peripheral frame 5 preferably notched to receive the peripheral edge of the speaker indicated at 6, This speaker is positioned to project sound downwardly through the open end of the cabinet.
To one side wall of the cabinet at the bottom is hinged a bafile plate! as indicated in Fig. 2 which lies at an angle to the horizontal and sound waves from the speaker strike this board and are reflected outwardly in a general horizontal direction. The baflle board will vary in its angular position by varying the angular position of the cabinet as shown by dotted lines in Fig. 2. Preferably, the bafile is hinged at one edge by means of the screws 8, one of which is shown particularly in Fig. 4, supported in one of the side walls of the cabinet. There are two screws one at each side edge of the bafile and each is threaded into a ferrule 9 and has an unthreaded end ID of cylindrical form entering a metal socket member II at the edge of the baffie 1. 10
Intermediate the ends of the board I is provided a sheet metal channel member I2 at one edge or both edges of the board. Into this channel extends a pin l3 supported on a leg I of the frame member. The pin is stationary and 15- the swinging of the cabinet causes the channel l2 to slide on the pin and to vary the angle of the board. This change in angle through the swinging of the cabinet on the trunnion hereinafter described may be increased by placing the pin IS on the leg l5 for instance of the framethat is, the nearer the pin I3 is to the hinge point 8 the more rapid will be the change in the angular position of the baflle plate I by tilting the cabinet.
The frame here shown consists of two leg members I4 and IE on each side of the cabinet preferably formed of tubing. Each pair of legs is secured to a block 16 at their upper ends on each side of the cabinet. The legs are outturned in a relationship one to the other as will be seen from Fig. 2 and a metal strap or bar [1 extends from a leg on one side of the cabinet to the companion leg on the other side of the cabinet. Thus there are two straps or bars H as will be clearly 35 understood from Fig. 2 providing a solid support for the cabinet. The block I6 is recessed as indicated at IS in Fig. l.
The cabinet proper on each side is provided with a circular disk 19 which is positioned in 4 the recess of the respective block l6 and the recess, as will be understood from dotted lines in Fig. 2, is circular at the bottom and has a width equal to the diameter of the disk l9. Thus the disk through at least half its periphery is in frictional contact with the recess wall and the cabinet simply rests in the recess in the two blocks IS on opposite sides of the cabinet by gravity and due to the extent of the surface contact of the disks with the recess, it will remain a in any of its usual tilted positions. The blocks H5 at the top are each provided with lugs 20 to receive the respective end of the U shaped handle 2| extending across the cabinet at the top and supporting the two blocks from being spread 55 apart. The bars I! serve this same purpose at the bottom.
By this arrangement a new character of framework is secured of desirable form and of unique structure particularly in the provision of the trunnions which consist of the disks l9 and the blocks l 6. This permits the cabinet to be readily tilted and enables the device, when of small size, to be readily carried from place to place in a room and to be mounted upon a table or other surface at the desired height from the floor and by tilting the cabinet the sound waves may be caused to emanate at different angles to the horizontal.
The usual radio cabinet is constructed to project the sound waves horizontally. If the cabinet is of the proper height this will be found quite satisfactory but by a construction enabling the angle to be changed to suit the character of the room or the position of the cabinet as to height, I have been able to secure a more universally satisfactory result in that the sound waves may be directed angularly upward if desired or practically in a direct horizontal line or below it, depending upon the point of the hinge element and its point of slide connection with the frame. Thus all the beneficial effects that may be attained through an inclined speaker are obtained and the device may be adjusted to suit the convenience of the listener or of the room in which the cabinet is positioned. In other words, the angle at which the sound waves emanate from the apparatus in some rooms would be different from that in other rooms to secure the best sound effect.
Thus by mounting the cabinet on trunnions, I am able to secure varying effects as to emanation of sound waves and so far as the tilting of the cabinet is concerned, the invention is not confined to the positioning of the speaker as shown in Fig. 2. This speaker, as is indicated at 6 in the small sketch, Fig. 5, may be positioned to project the sound through one of the side walls I of the cabinet and due to its being mounted on the trunnion, the angle at which the sound waves are projected may be changed simply by tilting the cabinet.
In the construction of Fig. 5, the cabinet wall I is to be understood as being apertured and the speaker 6*- positioned in the proper relation with the aperture to project the sound waves through the wall at a right angle to the surface of the wall. The arrangement therefore produces the desired result in directing the sound waves at an angle to the horizontal either upwardly or otherwise.
From the foregoing it is believed evident that the various objects of the invention are obtained by the construction described. The tilting of the cabinet may readily be secured with the hinged bafi'le board as shown in Fig. 2 or by positioning the speaker to direct the sound waves from one of the side walls of the cabinet. Further, in either of the forms of construction, I am able to provide the control buttons 22, 23 etc., on the front wall of the cabinet and the tilting of the machine as shown by the dotted lines in Fig. 2 or 5 positions the control devices and dial for more ready operation and does not require the operator to stoop to the level of the buttons to adjust the same or to observe the dial. This result is attainable in either of the forms shown, I, 2, or 5, as the control dials may be on the same face of the cabinet through which the sound from the speaker is projected.
It will also be observed from the foregoing that the various objects of the invention are attained by the construction described.
Having thus briefly described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. A radio cabinet comprising a cabinet structure for the support of a radio set and loud speaker therewithin, the speaker being mounted in a wall of the cabinet to transmit sound waves to the exterior thereof at a right angle to the said wall, and a trunnion providing the sole support for the cabinet and permitting the same to be tilted to varying degrees and thereby vary the angle of transmission of the sound waves.
