4 Claims. -464) This invention relates to drinking-glass washer brushes and more especially to that type of glass washers that is made adapted to provide a simultaneously cleansing contact with both the exterior and interior surfaces of the glass. 7

The objects of the invention are not only to provide a washer for the simultaneous cleansing of theentire surfaces of drinking glasses, but also to provide a washer adapted to accommodate different sizes of drinking glasses; to provide for such a washer a base adapted to immovably secure itself to a flat surface upon which it is placed until it is intentionally removed; and to provide for such a washer the manner of detachably securing brushes to its base against withdrawal by the utilization of the same means employed for assembling parts of the base.

With reference to the accompanying drawing the Figure 1 is a perspective view of the improved glass washer; the Figure 2 is a cross-sectional rear view of the base of the washer illustrating fragmentary parts -of brush stems seated and secured to the base; and the Figure 3 is a skeleton top View of intermeshing brushes.

Referring more particularly to the details of the drawing, the base 20, preferably made of a metal casting, has the upper-face 2| and the under-face 22. The under-face 22 is provided with the central concave surface 23 and the upperface 2| supports the sockets 24, 25 and 26 around a central area 2 of the upper-face 2|. Companion brushes 28 and 29 are provided with the vertical stems 30 and 3|, respectively, with their lower projections 30A and 3 IA seated within their respective sockets 24 and 25. A marginally supported stem '32, with its lower projection 32A seated within the socket 26, is provided at its upper extremity with the smaller brush 32B for a purpose to be later explained. The bristles extremities of the companion brushes 28 and 29 intermesh, and the bristles extremities of the smaller brush 32B intermesh with the bristles extremities of both companion brushes 28 and 29, as illustrated by the Figure 3. Each brush 28, 29 and 32B is provided with a vertically erect tuft 28A, 29A and 320, respectively, for a cleansing contact with the interior bottom surface of a glass placed thereon. The vacuum mat 33 is of wood-screws 34 being then made to enter the 55 be readily removed for stem-ends of the projections 30A, 3|A and 32A, thereby securing by the same means both the vacuum mat 33 and the various vertically supported brushes 28, 29 and 32B in such manner" that they easily can be detached for replacements.-

The applicant is aware that the artdiscloses the use of vacuum cups employed in connection with glass brush washers as a means of stability, the cups therefor being distributed beneath the base of the washer at points believed at the time by the designers to be best in securing the base against movement during the use of brushes seated within a centrally supported socket and surrounding sockets.

In the improved washer however it has been found most advantageous to locate no socket on the central area 21 of the upper-face 2| of the base 20, but to place a plurality of sockets, such as 24, 25 and 26 (more or less in number as may be desired) around the outside of the central area 21, and then, in place of vacuum cups hitherto used at distributive points, to employ the vacuum mat 33 with greater holding power exerted marginally within and beyond the annular scope of the plurality of sockets supported by the upper-face 2|.

For use, the improved glass washer is placed within a tank and, as the base of the washer rests on the floor of the tank, the vacuum mat 33 immediately anchors the washer against all accidental movement. With the tank of course supplied with water and cleansing material the larger glasses are in turn placed over and pressed down upon either of the companion brushes 24 or 25 and manually revolved. This treatment of the glass contacts its interior surface, including its bottom surface, with that brush and its tuft and, at the same time the exterior of that glass is contacted with the other companion brush and,

incidently too, with the smaller brush 32B although the use of the smaller brush 323 being primarily intended for smaller glasses which, in the same manner as the larger glasses, are each thoroughly cleansed interiorly by the smaller brush 32B and its tuft 32C and externally by simultaneous contact with both of the companion brushes 28 and 29.

To release the vacuum mat 33 from its tenacious hold on the floor of the tank a finger entered at any place under the mat rim will permit the washer to be lifted out of the tank.

To replace either the vacuum mat 33 or any of the brushes 28, 29 and 323, the screws 34 may the purpose.

While in the drawing three brushes are illustrated as being supported by sockets with which the base is provided on its upper-face around a central area, the right is here reserved, in connection with the use ,of the vacuum mat 33, to employ more or less than three brushes as may be desired.

I claim:

1. A drinking-glas washer having a base comprising two spaced sockets, each of said sockets having a vertical axis and an enlarged circular lower base portion and merged, one with another, to integrally provide a base outline substantially in the form of a figure 8 and upon the upperface of said base supports for multiple brushes; a concave underface provided within said outline; a vacuum mat having a flat marginal portion extending beyond and all around said outline thereby providing a mat in the pattern of an enlargement of said outline; and brushes having projecting stems secured one within each socket.

2. A drinking-glass washer brush support of intercommunicating bristle brushes having stems, the support comprising a single compact body unit; a plurality of sockets integrally formed face in all directions beyond that over which the support and the bristles of the supported brushes extend.

3. A drinking-glass washer comprising a base structure providing upon its upperface a support carrying multiple upright brushes, said base provided with a concave underface; a vacuum mat of uniform thickness centrally secured to said underface, said mat including a continuous flat marginal border extending beyond said underface, said base having a rim portion surrounding said underface and resting upon, and supported by, said flat marginal border of said mat, whereby said vacuum mat is adapted for a partial vacuum grip upon any fiat surface from which it may be released by the slight lifting of an edge of the mat.

4. A base for a vertically supporting glass cleansing device, the base comprising a rigid body unit, said base having a central concave underface; a vacuum mat of uniform thickness throughout its entirety and centrally secured to said concave underface, said mat including a continuous fiat marginal border extending substantially beyond said underface; and a rim portion of said base surrounding said underface and resting upon, and supported by, said fiat marginal border of said mat of which a substantial marginal portion remains exteriorly of said rim and thus made adapted for an increased partial vacuum grip upon any fiat surface upon which the device is placed and from which it may be released by the slight lifting of an edge of the mat by means of a finger placed thereunder.
