Application November 10, 1936, Serial No. 110,069 2 Claims. (01. 248-206) My invention relates to improvements in dish structures wherein the dish portion is turnably supported. by a re-inforced rubber bracket provided with a deflectable annular flanged base 5 having therein a vacuum or suction creating chamber whereby the bracket may be attached to any suitable vertically disposed surface; and the objects of improvement are, first, toprovide a dish structure that may be attached to a smooth 10 vertical or inclined. surface without marring the finish of the surface; second, to provide a vacuum or suction supported dish structure for attachment to vertically disposed surfaces; third, to provide a vacuum or suction supported dish strucl5 ture that may be readily attached to any suitable vertical surface; fourth, to provide a vacuum or suction supported dish structure of ornamental appearance; and, fifth, to provide a dish structure as above, of simple construction and cheap to manufacture,

A clear understanding of my present invention, whereby the attainments of the objects stated are secured, as well as others not enumerated, may be had from a perusal of the following description when taken in connection with the accompanying drawings, in which:

Figure l is a side elevation of my improved dish structure attached to a vertically disposed surface.

Figure 2 is a front elevation of my improved dish structure.

Figure 3 is a plan view of my said dish structure.

Figure 4 is a sectional view of my said dish 5 structure taken on line 3-3 of Figures 2 and 3.

Figure 5 is a sectional View of my said dish structure taken on line 55 of Figure 4.

Figure 6 illustrates a different embodiment of my improved dish structure than as shown in the previously named figures.

Throughout the several views of the drawings, similar numerals refer to similar parts, and referring thereto:

I represents, in section, the vertical back of a sink or other vertically disposed wall having a substantially smooth outer surface 2 to which is secured supporting bracket 3 by vacuum or suction created within suction chamber 4 which is sealed against entrance of air by atmospheric pressure against the flexible annular flange B flaring outwardly from the outwardly horizontally extending body portion of the soft rubber composition supporting bracket 3, which is reinforced by sheet metal stiffening member 8, provided with perforations 9 through which extend joining portions I of the rubber composition supporting bracket 3. The reinforcing member, at its portion farthest from the suction chamber 4, is bent into tubular form, as designated by numeral H and, which has outwardly extending bead-like bearing flange H2 at its top against which rests collar iii of the dish trunnion I land between which and the head it is clamped the bottom member it of the dish portion ll, having at its central portion depression l8 so formed that the top surface of the head I will be on the same plain as the top side of the bottom member It. At the upper edge of the dish portion I1 is outwardly extending beadlike flange Hi. This bead-like flange presents a curved surface which allows easy cleaning and also stiffens the outer wall of the dish portion and adds to the appearance of the dish portion.

In Figure 6 the dish portion I1 is illustrated as secured to the trunnion M by a headed pin 20 driven into a hole drilled axially into the trun-- nion 14.

To assist in arriving at a clear understanding of my present invention, I refer to the method of producing the same, and referring thereto,

I provide a suitable mold in which to form and vulcanize the rubber portion of the supporting bracket 3 and position within the mold the sheet metal re-inforcing member 8 having the tubular portion l I in such manner that the extended reinforcing portion having perforations 9- will extend toward the flexible flange 6 and the tubular portion II will be spaced away from the said flange with its bearing flange l2 at the side of the mold. I' then introduce a rubber compositicn which is plastic into the mold until the mold is filled and the plastic composition extends through the perforations 9, forming binding members I0 and then subject the mold together with the plastic rubber composition to a vulcanizing temperature for a suificient period of time to vulcanize the said composition to the degree of flexibility desired, and thereafter remove the vulcanized supporting bracket together with the reinforcing member therein from the mold and having produced the dish portion with its extended trunnion, I introduce the trunnion in the tubular portion l l of the metal reinforcing member, thus completing my improved dish structure in which completed state it may be attached to any substantially smooth vertical wall surface by pressing the structure against the said surface with sufficient force to collapse the suction chamber A to a reduced capacity and allowing the suction chamber to be expanded by the flexible flange 6, thus causing a vacuum or suction to be formed within the chamber 4 and thereby draw the supporting bracket securely against the wall surface with suflicient force to support the entire dish structure, which force is governed by the size and. capacity of the suction chamber which is sealed against entrance of air by the flexible flange 6 bearing against the wall surface 2.

Having described my invention, I claim:

1. In a dish structure, the combination comprising adish portion having a downwardly extending trunnion secured thereto with a bearing collar adjacent the bottom of the dish portion, a deflectable supporting bracket having a suction chamber at one of its ends and a vertically disposed sheet metal reinforcing member in the said supporting bracket and extending substantially horizontal from adjacent the said suction chamber a distance equal to more than one-half the width of the dish portion, the end of said reinforcing member bent at its portion farthest removed from the suction chamber into a vertically disposed tubular portion for loosely engaging the said downwardly extending trunnion, the said tubular portion having an outwardly extending bearing flange at its top for engagement with the said bearing collar of said downwardly extending trunnion.

2. In a dish structure, the combination comprising a horizontally disposed metal dish container portion having at its axis a downward extending trunnion rotatable in a tubular portion of a horizontally extending perforated sheet metal bracket reinforcing member, substantially wholly surrounded by a resilient rubber bracket having in horizontal spaced apart relation to the said tubular portion a vertically disposed flange having therein a suction chamber.
