HARRY PHILLIPS, OF GREENWICH, CONNECTICUT Application filed July 22.

This invention relates to radio receiving sets and has for its objects to insulate the cabinet structure containing the'radio apparatus against vibration and to accomplish this with a simple practical commercial form of construction, readily applicable to existing radio apparatus and further of such a form as not to mar the generally artistic appearance of the modern radio receiving in cabinet.

In the drawing accompanying and forming part of the specification, several different embodiments of the invention are illustrated, but it is to be understood that the structure may be-further modified without departure from the true spirit and broad scope of the invention.

Fig. 1 in the drawing is a front elevation of a radio cabinet having the present improvements incorporated therein; Fig. 2 is an enlarged front elevation and partbroken sectional view of the cushioned leg construction of-the cabinet; Fig. 3 is a detail sectional view as on the plane of line 3-3 of Fig. 2;

Fig. 4 is a broken sectional detail of a slight modification in the structure of the upper leg cushion; Fig. 5 is a cross-sectional detail as on lines 55 of Figs. 2 and 4; Fig. 6 is a broken sectional detail of another form of the lower leg cushion; Figs. 7 and 8 are broken sectional details of base cushions similar to those shoyvn in Figs. 1 and 2; Fig. 9 is a similar e rged view of the form oflbase cushion wn in Fig. 6.

The ca inet containing theradio appara tus is indicated generally at 10 and it should be understood that the same may be of any usual or special construction and of the consolelttype shown, the table type of cabinet, or

- any/"other style..

. Interposed between the cabinet and its support, whether the latter be a floor, table or stand for instance, are cushioned feet which absorb and prevent transmission of vibrations to the cabinet proper.

In the illustration, the cushioned supports are in the form tjf legs 11 having cushioned sockets in the cabinet base, cushioned intermediate portions and base cushions at the floor.

1929. Serial No. 380,125.

The cushion sockets for the legs are shown in Figs. 2, 4 and 5 as over-size seats 12 for the cylindrical upper ends 13 of the legs or corner posts, said seats having grooves 14 therein receiving longitudinal strips 15 of rubber or other non-microphonic cushioning material, which project from the grooves into yielding engagement with the cylindrical portion of the post. As shown particularly in F ig. 5, these rubber strips may be widened at their inner portions, somewhat in T-form to grip the post and positively prevent'contact between the post and the socket formed in the corner structure 16 of the cabinet. A pad or pads 17 of rubber or other suitable vibration absorbing material may be placed in the socket to take the end thrust of the post. This construction enables the post to vibrate in the socket in various directions without imparting such vibrations to the there can be no transmission of vibration from one solid portion to another.

The intermediate portion of the le or post is shown cushioned in Figs. 3 and 6 y making the post with relatively telescopic sections 20, 21, free of contact with each other and hollowed to contain a cushioning spring 22,

which latter is encased by a flexible sleeve 23 of rubber or the like to keep the leg sections aligned and out oi mechanical contact. Pads of cushion material 24 take the end thrust of the sustaining spring, and if desired, a rod- 25 may be placed within the spring to aid in ali ning the leg sections.

dditional cushioning effect is obtained in the illustration by employing a base cushion for each leg made up of discs 26 of suitable. sustaining material, such as wood, hard rubber, bakelite or the like, superposed one on the other with interposed pads or rings 27 of rubber, felt or other non-microphonic cushioning material, it being noted in this instance also that the solid portions 26 are maintained by the cushioning material out of material having cavities in opposite faces of contact, so that there can be no mechanical thesame and cushions of softer material fittransfer of vibration from one part to anting in said cavities and pro ecting beyond other. not to contact, is e ected by arranging the pads or cushions 27 in positioning seats 28 in the solid members. In Figs. 7 and 9, companion seats are formed in the opposing. faces of the discs to fit the cushions which thereupon position the members laterally one with respect to the other. In Fig. 8 the discs are made one sufiiciently smaller than the other to avoid contact, and if desired, the pads 27 may be-secured by adhesive or the like to the adjoining discs, so as to position the latter against possibility of contact. One or a number of the discs may be employed and the lowermost disc may have one of the cush-' tions and holds the relatively movable parts separated against mechanical contact. The ru ber pads also have an electrical insulating effect, which is of importance where the supports for the cabinetare of a metallic nature.

The invention is of simple construction, durable to last the life of the cabinet and can be inexpensively made and applied to radio cabinets, without detracting in any way from the general appearance of the cabinet.

The base or floor cushions when made up of superimposed discs of successively smaller size have an ornamental pyramidal appearance and may be of square, angular, circular or other outline to provide difierent ornamental effects.

What is claimed is:

1. In combination with a radio cabinet, supports therefor, comprising superposed discs pyramidal one on top the other and of successively smaller sizes with pads of nonmicrophonic cushioning material between adjacent discs, said pads being interlocked in opposin faces of adjoining discs to stabilize the mu tiple cushioned structure against lateral displacement.

2. As a new article of manufacture, a. support for radio cabinets comprising discs of relatively hard material, said discs being of different sizes and having cavities in opposite faces'of the same and cushions of softer material proportioned to fit in said cavities and to hold the discs separated when pyra- This spacin of the members, so as the surface of the disc.

In testimony whereof I aflix my si nature.

HARRY PHIL IPS.
