3 Claims.

rfhis invention relates to glass cleaning devices and it has reference more particularly to the provision of a practical and conveniently usable `means for the cleaning of drinking glasses, such as those used in restaurants, taverns and like places; it being the principal object of the in vention to provide a glass cleaning device whereby the inside of a glass may be vcleaned by the action of a brush and the outside cleaned 'and wiped by one or more sponge or foam rubber brushes that better serve to remove nger marks, lipstick and other substances that are diiicult to remove or cannot be removed by the usual rinsing in Water or light brushing.

It is also an object cf the invention to provide a device of the above stated character 4wherein provision is made whereby the intended manual application of a drinking glass to a bristle brush 'in a cleaning operation will operate automatically to bring the rubber brushes into -contact with the outer surfaces and rim of the glass for their `functional operation of cleaning these parts while the bristles cleanse the inner surfaces of the glass.

Another object of the invention is to provide a means of applying the rubber brushes for effectively and quickly wiping lipstick from the rim of the glass, both along the inside and outside thereof.

Still further objects reside in the details of construction of parts, in their combination, and mode of use as will hereinafter be fully described.

In accomplishing the above mentioned and other objects of the invention, I have provided the improved details of construction, the preferred forms oi which are illustrated in the accompanying drawings, wherein:

Fig. l is a perspective view of a glass cleaning device embodying the improvements of the present invention therein.

Fig. 2 is a central, vertical section of the same.

Fig. 3 is a side view of one of the outside brushes, showing its attachment to a, bell-crank form of mounting lever.

Fig. 4 is a cross-section on line lt-fl in Fig. 3, illustrating the construction of the brush and the manner of mounting it in the bell-crank lever.

Referring more in detail to the drawings:

In its present preferred form of construction, the device comprises a circular metallic and horizontally disposed base member Ui, to the under side of which there is fitted and secured a rubber disk l2 of substantial diameter, serving as a suction cup element whereby the device may be held secure while in use upon a flat surface. Formed centrally on the base member is `a boss l 3 in which a short tubular guide member lil is iixed. This member extends a short distance above the boss, as noted best in Fig. 2.

Slidably contained in the tubular guide lll is a sleeve I5, held against rotative movement in the guide and its vertical movement limited by means of a pin or stud I5 xed on the sleeve and extended into a vertical slot Il formed in the upper end portion of the tubular member lll. At its upper end, the sleeve l5 has a directly outwardly turned flange IB for a purpose presently understood.

Fitted securely in the sleeve l5 is the lower end portion of a vertical stem or standard 2U, of wood or other suitable material, mounting a, bristle brush 2l along its upper end portion. This brush is shaped to conform to the inside of a drinking glass when the glass is placed thereover :for cleaning, as shown in Fig. 2. At its upper end, the standard mounts a tuft of bristles 2d for brushing or cleaning the inside surface of the bottom of the glass as applied thereto.

Extending upwardly from the peripheral portion of the base lll, at equally spaced intervals thereabout, are standards 25. Mounted pivotally upon each of these standards is a bell-crank lever comprising a substantially horizontally directed arm 25:0 and an upright arm 2611/. The arms 26a: extend radially from the brush standard i]l and are pivotally mounted intermediate their ends by pivot pins 2B. At their inner ends they engage against the under side of the flange t8 of sleeve l5 as noted in Fig. 2. The arms Zly extend upwardly from the outer ends of arms 26:1: beyond the points of pivotal support of the levers by the pivot pins 28. The arms 26g are of channel form in cross-section as seen in Fig. 4. Each of these arms mounts a brush 29 of foam or sponge rubber, for wiping the outside and rim surfaces of a glass when applied to the device as indicated in Fig. 2.

Each brush 29 comprises an elongated block of the selected material. Its outer longitudinal portion is contained between sheets of stiff rubber sil-3B, or the like, yas seen best in Fig. 4. These, in turn, are fitted in a U-shaped brush back 3| of metal, and the said back 3l is contained in the inwardly faced channel-shaped arm 25g of the supporting bell-crank.

It is noted that the various brushes 29 are pivotally xed in the arms of their respective levers by horizontal pivots 35 extended through the upper ends of the arms 261,/ and through the brush backs 3l at points medial of the upper and lower ends of these brush backs. The brushes are thereby held for pivotal action in the channel shaped arms 26g but can tilt as necessary to allow the rubber brushes to conform to the slope of the walls of the glass.

A coiled spring @t is located under compression about the sleeve l5, to bear at its lower end against the base it and at its upper end against the inner end portions of the bell-crank arms 26x. The spring operates to yieldingly retain the bell-crank levers :Qty outwardly inclined, for example as lshown in dotted lines in Fig.2;'t`nus to hold the brushes 29 outwardly and away from the bristle brush. However, when a glass, such as indicated at .'iii, is placed in an inverted, position over the bristle brush, and a downward pressure applied, the bristle brush,througn pressure of the glass, will be moved .downwardly against the pressure of the spring 40 and force Vwill be applied through the flange i3 toi sleeve l5 against the inner ends of arms 2te.n to cause .all bell-eranlnarms to swing Vthus to pressthe `brushes 29 against the 1outside surface of the glass. Thenpby .a rotative turningr .ofithe Aglass as' :held in the hand, vthe glassv will When down be'brushedboth-insideandoutside. vwardpressure against the glass is removed, `spring -filil restores. the pants `to normal position.

With the parts `so constructed and assembled, the yuse :of the device isa-s follows:

"First, A-thevdevice is .set-in a.Y pan. or basin v.of l f wash water,l the water level coming approximately upto the top of the brushes. A glass 'liebe `washed .is grasped :by its lower ,vend and-ao plied Tin an Ainverted position., directly over the bristle brush-and ispressed .downwardlymntil u thereof. will be pressed :tightly .into Acontact with Y Vthe wall :oftne glass as .indicated-fin 41, :also .against `.tl-ie rimof theglass, anddne .to its ipressure :against the rim, will curl upwardly and against -the .inside .of the rim surface, thus to 'eiiectively contact all :surfaces 'ofvr the rim with cleaning -eeet when .the glass is rotated.

VZraving thus; describ'edxmy invention, what I .claim .as :new .therein and desire to-secure .by Letters"Patent :.is1: Y
