28 Claims.

This invention relates to washing machines, and more particularly to washing machines for glasses, tumblers and the like.

One of the principal objects of the invention is the provision of a washing machine for cleansing glasses, tumblers, and like articles which is simple in construction, efiective and eflicient in operation to wash both the outside and inside of the articles.

Another object 01' the invention is the provision of such a glass or tumbler washing machine having brushes adapted to be telescoped by a tumbler, and means for causing the washing fluid to fill the interior of a tumbler during the brushing action.

Other objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims.

In glass washing machines wherein a tumbler or like article is submerged in washing fluid, and while held in an inverted position is subjected to a rotary brushing action, it is diihcult to thor- 40 oughly cleanse the interior of the article because the air entrapped in the inverted tumbler arid the centrifugal action of the rotating brushes prevent the entrance and circulation of washing fluid through the interior of the article being 5 cleansed. The drawings, in which like characters of reference designate like parts throughout the several views thereof, illustrates a washing machine which is particularly adapted for eflectively cleansing tumblers and like, and which provides 50 for thorough cleansing of the interior of such articles by subjecting the interior to suction so that a positive circulation of washing fluid therein is obtained. The washing machine illustrated is arranged to provide for both washing and rinsing 55 of tumblers and like utensils. As shown, the machine comprises a suitable metal or other form of tank or liquid container III, carried upon suitable supporting legs, not shown, so that the machine is elevated to a convenient height for the operator. The washing unit designated generally by the nu- 6 meral it stands partially submerged within the washing tank Ill and arranged so that an inverted tumbler may be readily inserted. The unit II is provided with brushes for sweeping both the exterior and interior of a tumbler. 10

The washing unit is mounted upon a rotatable spindle 25 which extends up into the tank as is illustrated in Fig. 1. As shown, the spindle 25 extends vertically through an opening 28 provided in the bottom wall 21 of the washing com- 1 partment tank. The tank opening is closed by the spindle support 28 which comprises a plate 29 having a centrally extending hub 30 which projects through the tank opening It. The plate h spaced holes 3| for the insertion of screws 82 go that pass through the tank wall and into a bolting ring 33 on the interior oi the tank. A gasket 3! between the tank and plate serves to seal the tank opening upon drawing up the holding screws 32. The spindle support provides spaced bear- 25 lugs for free rotation of the spindle 25. A bearing I6 is carried by the plate part 20 directly beneath the packing gland 31. A second bearing II is spaced from the plate 29 by provision of meeting ribs 40. The axial positioning of the spindle 30 25 is maintained by provision of a thrust collar ll above the lower bearing 38 and a drive pulley l2 beneath this hearing. The pulley 42 carries a belt It connecting to a suitable source of power, which may be an electric motor.

In order to catch and drain away any shaft leakage so that it will not drip on the driving mechanism a cup like retainer 45 is carried by the spindle support ribs It and encircles the spindle 25 beneath the upper bearing III. This retainer is constructed with an outer cylindrical wall 46 of substantial height and an inner concentrically related vertical wall ll spaced from the spindle and of somewhat less height than the outer wall. An inclined gutter 48 is formed with a threaded connection for attachment of a waste pipe 48. A close fitting collar 50 is positioned on the spindle '25 adjacent the retainer and is provided with an outwardly flaring skirt ii that stands within the confines of the retainer outer wall 48. Any leak- 5 age along this shaft is thrown by the collar into the retainer from which it is carried away.

The upper end or the spindle is arranged to receive the washing unit in telescoping engagement, and is provided with a laterally extending stud 53 which afiords a driving engagement for the washer unit. The washer unit is arranged so that all of the brushes are carried by a common supporting member 55. As shown, brushes are arranged to sweep both the exterior and the interior of a tumbler. Means are provided whereby the interior of a tumbler telescoping the brushes is subjected to suction whereby washing fluid is caused to flow up to fill the interior of the glass during the washing operation. The suction is created by an ejector which is built into the brush supporting member 5.

As shown, the brush supporting member 55 is constructed as a unitary casting having a downwardly extending axial sleeve 56 that is receivable upon the spindle end, and a slot 51 that is engageable with the spindle lug 53, The upper end of the member 55, which is a continuation of the sleeve, has a socket 58 for reception of the inner brush 58. The socket 58 communicates with the ejector. The inner brush has a hollow stem or body portion with one or more openings therein. As shown, the brush stem has openings 88 at its upper end to afiord communication with the space on the interior of a tumbler.

The inner brush 59 is shown constructed of segmental bristle carrying parts 60 of arcuate section. These parts are proportioned so that they may be assembled to form the hollow stem of the inner brush. As shown, the segmental parts 60 are arranged to hold tufts of bristles as indicated at 6|. The bristles project substantially perpendicularly from the face of a segmental member and extend for substantially the full length of this member to the extreme upper end thus affording a distribution of bristles such that all parts of the interior of a tumbler are subjected to a sweeping action during the washing operation. The brush segments are assembled by application of a close fitting ferrule 84 over the lower ends of the segments. The segments are held in place by the provision of screws 65 which are proportioned to afford a stud projection 66 from the ferrule in assembly. The ferrule '54 and stud projections 66 form a bayonet latch that is engageable with the brush support sleeve 58 which has bayonet notches 51 for reception of the studs 56. The brush is thus readily attached to the supporting member in the position of use.

Additional brushes which serve to sweep the exterior of a tumbler, and which are indicated by the numeral 18, are mounted within a cylindrical sleeve II which extends axially of the spindle and which is attached to the supporting member 55 by engagement with an annular rim 12. The sleeve ll extends upwardly from the supporting member 55 and terminates some distance above the normal liquid level of the washing tank which is indicated by the numeral 13. A soft rubber ring 74 is applied to the upper end of the sleeve. As shown, this ring comprises an annular flange 15 which overlies the bead 16 at the top of the sleeve, and an inwardly extending flange 11 having an opening 18 of such diameter that a tumbler may be readily inserted into contacting engagement with the brushes.

As is shown in Fig. 5, the outer brushes 10 extend for substantially the full length of the enclosing sleeve H so that substantially the entire outer surface of a tumbler is subjected to the sweeping action of the bristles during washing. This construction may be modified somewhat to take care of glassware having a handle or other projection which would prevent its ready insertion within the sleeve of the construction illustrated in Fig. 1. As is shown in Fig. 6, the sleeve H carried by brush supporting member 55 is relatively short and has short brushes 10 of such extent that only a portion of the tumbler adjacent the open end is brushed.

As mentioned above, the ejector which is constructed within the brush supporting member is connected with the inner brush of the washer. This is accomplished by extending the socket 58 downwardly into communication with radial passages which terminate adjacent the periphery of the supporting member 55. The passages 80 are shown as being four in number, each of which opens into an elbow shaped passage 8| having an enlargement 82 which affords a flow path outwardly with respect to the end of the associated passage 80. The portions containing the passages 80, the elbow passages Bi and enlargements 82 are illustrated, in perspective, in Fig. '7 by the numerals 80 and Bi respectively. The passages 8| have inlet or suction openings 83 in the lower part of the member 55 some distance inwardly from the periphery thereof. The passages 8| open as indicated at 86 in the periphery of the supporting member 55 just to the rear of outwardly flaring projections 85. As is shown in Fig. 3, the brush supporting member is adapted for rotation in a counterclockwise direction. Just ahead of each opening the member 55 is flared outwardly as shown at 85 so that upon rotation a circulation is induced which enters the openings 83 and passes outwardly through the openings 86. The proportioning of these parts is such that an ejector action is afforded which creates suction within the passages 80 that are in communication with the hollow stem of the brush 59.

In order to restrain the tendency for the fluid adjacent the rotating parts to assume a rotary motion under influence of the rapidly rotating washing unit, which would thus diminish the effectiveness of the operation, baflles are provided adjacent the ejector inlets 83. As shown, the bolting ring 33 is provided with upwardly extending plates 90 which stand radially with respect to the spindle 25 and are positioned beneath the brush supporting member 55. These plates extend outwardly for some distance beyond the diameter of the washing unit and influence the movement of the washing fluid adjacent the lower part of the unit in a manner so as to reduce prerotation.

The washing compartment is shown as having a cover some distance above the normal fluid level with an opening 86 in alignment with the washing unit therebeneath. The opening 96 is of such size as to permit insertion of an inverted tumbler within the washing unit while held in the hand of the machine operator. A downwardly depending annular flange 91 extends from the cover 55 to beneath the liquid level. This flange is spaced from and encircles the brush sleeve H.

Upon inserting a tumbler within the washing unit so that the tumbler telescopes the rotating inner brush 59, suction acts to withdraw the entrapped air from within the tumbler and to concomitantly create a circulation of wash water upwardly into the interior of the tumbler. An upward circulation of washing fluid occurs over the exterior of the tumbler as well. The rotating shell and attached outer brushes 18 set up a centrifugal action which causes the washing fluid to rise upwardly within the shell to issume the usual paraboloid shape, and to thus overflow the lip of the ring 14 with resultant upward circulation through the glass washing zone. The

As shown, an inlet for the circulating water is aflorded within the brush supporting member I which has an opening III surrounding'the socket BI and deiined. by the inner edge ill of a ring: ifl'that extends inwardly fromthe rim I2. 'I'he flow or fluidthrough the "opening III is subjected to the action of the "plates ll.

By withdrawing the fluid from the brush top to create a circulation upwardly the entire brush is subjected to this cleansingaction.
