June-.16, 1931. o. P. LIEBREICH LOUD SPEAKER CABINET Filed May 5. 1927 INVENTOR Oscar P zebrczc/z ATTORNEY Patented June 16, 1931 UNITED STATES OSCAR P. LIEIBREICH, OF JACKSON IIEIGHTS, NEW YORK LOUD SPEAKER CABINET Application filed Kay 5, 1927. Serial No. 188,954.

The present invention relates to loud speaker cabinets and is more particularly d1 rected toward an article of furniture whlch functions both as a cabinet for a loud speak- 5 er and a shield or cover for a steam or hot water radiator.

In radio receiving, it is customary to em ploy a loud speaker for roperl reproducing music and speech, an in or er to repro- 10 duce all the notes, it is preferable to use a comparatively large vibratory cone or diahragm so as to satisfactorily reproduce the ower notes and improve tone quality. This results in a lar and more or less cumber- 1 some piece of urniture which does not fit well into the decorative scheme of the room. On accunt of the fragile nature of such large cones, they are frequently hung on the wall to prevent accidental dama 2 It is also customary to shiel or cover steam heating radiators in order to hide the unsightl radiator. These shields or covers also eflect the heat from the radiator into the room and prevent the soiling of draperies and the smudging of walls on account of the dust carried up in the hot air from the radiator.

The present invention contemplates an article of furniture wherein the radio loud eaker and radiator cover or shield are combined into a single unit of furniture. I have found that when a loud speaker is incorporated in a radio shield or cover that the unsightliness of the radio loud speaker as well as the radiator is eliminated by one and the same article of furniture. The same shield serves as a protection for the speaker and as a heat and dust deflector for the radiator. This construction permits placing of the radio loud speaker near the floor where the source of sound appears more natural.

The accompanying drawings show, for purposes of illustrating the invention, one of the many possible embodiments in which the invention may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings: Figure 1 is a perspective view of a combined radiator cover and loud speaker cabinet' Figure 2 is a central sectional view through the same; and

Figure 3 is a sectional View takenon the 55 line 3-43 of Eigure 2.

As indicated in the drawings, the cabinet is made somewhat larger than the radiator, so as to cover the radiator and so as to carry the loud speaker in front-of the radiator. In the drawings, the radiator is indicated at 10. The cabinet has a top 11, end walls 12, and a front wall 13. The ends and front of the cabinet are provided with grille work as indicated at 14, 15 and 16 to facilitate the circ'u lation of air heated by the radiator. As indicated in the drawings, the front lower part of the cabinet is provided with a compartment formed by horizontal boards or the like 18 and 19, which extend from one end wall oi the cabinet to the other end wall. A sounding board 20 is placed a slight distance in front of theradiator. A loud speaker unit 21 is carried on a suitable-frame 22 fastened inside the compartment 17 and thisloud s aker unit is connected with a vibrating diap ragm such as a cone 23. The lower front part of the cabinet may be provided with door'frames carrying drapery, grille-work or a screen, as indicated at 25. The doors permit access to the unit for purposes of ad'ustment.

When a combined radio loud speaker and radiator cabinet is employed as indicated in the drawings, it will be'apparent that the combined unit may be placed over and adjacent -8 the radiator so as to cover the radiator and at the same time direct the heat from'the radiator and prevent the dust from accumulating on the draperies of the rooml Where-a high radiator is to be covered one can easily place a comparatively large cone-type speaker in the cabinet; where the radiator is low, a rectangular wooden diaphragm speaker of a conventional roll type of speaker may be used. The sound produced by the loud speakor unit will come out through the ends and front of the unit and spread through the room in a pleasing manner. The sounding board 20 assists in amplifying the sound and in directing the sound waves out into the at all times room. It is apparent that the combined unit will carry the loud speaker near the floor and this will bring about more natural reproduction than is the case where the loud speaker is mounted at a high elevation such as by hanging it up on the wall. The cabinet will protect the loud speaker from damage.

The entire cabinet resembles a piece of household furniture and effectively conceals both speaker and radiator with attendant advantages. The front can be provided with grilled doors to resemble a bookcase or any other similar piece of furniture and the entire cabinet can be finished to harmonize with any type of furniture.

It is obvious that the invention may be eInbodied in many forms and constructions, and I wish it to be understood that the particular form shown is but one of the many forms. Various modifications and changes being possible, I do not limit myself in any way with respect thereto.

What is claimed is:

1. A combined radiator cover and loud speaker cabinet having an open back comprising a frame work having a vertical longitudinally extending divider therein, the said divider terminating short of the top and bottom of said cabinet, horizontal partition members extending between the top andbottom edges of said divider and the front of said cabinet to form a compartmenhthe sides of said cabinet above and behind said com artment being enclosed by grilles and the ront and sides of said compartment being enclosed by screens. Y

2. A radiator cover comprising a cabinet having a frontanda rear compartment, said rear compartment being adapted to enclose a radiator and having means for transmitting the heat therefrom to the outside of said cabinet, said front compartment being adapted to retain a loud speaker unit and protect it from exposure to heat from the radiator and having means for transmitting the sound waves from said cabinet.
