Silencer

Application filed February 1, 1922. Serial No. 583,333.

To all whom it may concern:

Be it known that I, Harold A. Freeman, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles 5 and State of California, have invented new and useful Improvements in Silencers, of which the following is a specification.

My invention relates to a silencer that is adapted to be positioned on the base por10 tions of various articles formed of glass, earthenware, metal, etc., for the purpose of eliminating the noise produced when the articles are placed on a supporting surface, and likewise protecting the articles against 15 breakage and also from marring the surfaces on which they are positioned.

The principal objects of my invention are to provide a combined silencer and cushion that may be easily and cheaply produced, 20 readily applied to the periphery of the base of various articles such as bowls, vases and various office appliances that are usually placed on the tops of desks and tables and, further, to provide a device of the character 25 described that is constructed so that it will firmly adhere to the article on which it is positioned, said device having its under face formed so that it will tend to adhere to the surface on which it is positioned, thereby 30 holding the article on which it is placed in proper position upon a supporting surface.

With the foregoing and other objects in view, my invention consists in the features of construction and combination and ar36 rangement of parts hereinafter more fully described and claimed, reference being had to the accompanying drawings, in which—

Figure 1 is an elevational view of a combined silencer and cushion of my improved <0 construction, showing the same applied to th. base of a desk-set telephone;

Figure 2 is a perspective view of the combined silencer and cushioning device, the same being shaped to be applied to the rec45 tangular base of a receptacle or appliance;

Figure 3 is a sectional perspective view of a portion of a combined silencer and cushioning device of my improved construction;

Figure 4 is a sectional perspective view of 50 a portion of a modified form of the silencer and cushion.

The body of the combined silencer and cushion which is formed of rubber or analogous material is substantially Z-shaped 55 in cross section and comprises a horizontally disposed base portion 10 from the outer edge of which extends upwardly and inwardly an inclined web or wall 11 and formed integral with the upper edge of said web or wall and occupying a position directly above «0 the central portion of the base 10 is a relatively narrow flange 12, and that portion thereof that projects beyond the wall or web 11 is provided with an inclined or beveled under surface 13. es

The combined silencer and cushion thus constructed may be in the form of a ring, as illustrated in Figures 1 and 3, or it may be square or rectangular as shown in Figure 2, the shape of the device depending, of 70 course, upon the contour of the base portion of the article to which said device is to be applied. The support engaging underface of the base 10 is provided with a shallow annular groove 14 that is so undercut as to 76 be substantially dove-tail shape in cross section, thereby providing a pair of oppositely disposed inwardly inclined antislippage shoulders 15, the edges at the lower ends of said shoulders being adapted to 6® engage the surface upon which the device is positioned and resist movement of the device in any direction.

Formed in the upper face of base 10 and suitably spaced apart are recesses 16, which 85 when the silencer is positioned on an article perform the functions of vacuum pockets to cause the device to firmly adhere to the article. . If desired, the inner or under face of the inclined wall or web 11 may be pro- 90 vided with these vacuum pocket forming recesses 17, as illustrated in Figures 2 and 4, thus providing additional means for insuring the retention of the device upon the receptacle or appliance. 95

Inasmuch as the wall or web 11 overlies the greater portion of the base 10, a horizontally disposed V-shaped . article-receiving channel is produced between the parts 10 and 11. which channel receives the base of an 100 article such as a bowl, vase, telephone stand, or office appliance, and when applied to such an article the latter may be placed on a metal, glass or finished wood surface without noise and without marring the surface 105 and also without danger of breaking the base portion of the article to which the combined silencer and cushion is applied. The flange 12 projects outwardly a short distance from the wall of the web 11 in order ilO

1,462,036 to form a part that may be readily engaged when the device is removed from the base portion of an article or appliance.

A combined silencer and cushion of my 5 improved construction is comparatively simple, may be easily and cheaply produced, and is very effective in performing its intended functions.

It will be understood that minor changes 10 in the size, form and construction of the various parts of my improved silencer and cushion may be made and substituted for those herein shown and described without departing from the spirit of my invention, 15 the scope of which is set forth in the appended claims.
