3 Claims.

This invention relates more particularly to means for washing or cleaning drinking vessels, such as tumblers, liquor glasses, mugs and the like, that are used in drinking parlors and at soda fountains.

The principal object of the invention is to provide improved and simplified means whereby such work can be done rapidly, thoroughly and economically. Other objects of the invention will 19 appear from the disclosure herein.

The invention is embodied in the example herein shown and described, the feature of novelty being pointed out in the claims.

In the accompanying drawings- Figure 1 is an elevational view of the mechanism according to the invention with some parts omitted and broken out for the sake of clarity.

Fig. 2 is a plan view from the line II--II, Fig. 1, showing the water supply means and control means therefor.

Fig. 3 is a top plan view looking at the turn table and brushes carried thereby.

Fig. 4 is a detail sectional view, on the line IV-IV, Fig. 1, of the pedestal and a portion of the water conducting means.

Fig. 5 is an elevational view of a pair of the brushes shown in the lower portion of Fig. 3 and their mountings in the rotatable table.

Fig. 6 is a detail view partly in section of the valve and means for actuating the same to control the water supply.

Fig. 7 is a detail, in plan view, of the mountings for the group of brushes shown at the left hand side of Fig. 1.

In the views, and referring more particularly to Figs. 1 and 4, the character l designates a suitable pedestal or stand having at its center a hollow member or chamber H from which latter is an upwardly extending tubular bearing l2. On the said bearing i2 is a rotatable sleeve 13 having fixed on its lower portion a cam 14.

Secured to and engaged by pins l3 with the upper end of the sleeve 13 to rotate therewith is a circular table I5, said table being retained so engaged with a screw and loose washer or keeper l3 The inner surface of the sleeve 13 is provided with an annular channel [6; and the spindle has a lateral passage coinciding with said channel, there being an outlet therefrom in the 50 sleeve with which a pipe is connected so that water under pressure coming into the chamber I I discharges through the pipe I! in all positions of the rotatable sleeve.

In order to provide for the scrubbing of various sizes and forms of ware and portions thereof the table I is provided with three sets of brushes, as best depicted or suggested in Fig. 3. Taking first the set in the lower portion of Fig. 3, it will be noted that the two brushes are elongated loops of twisted wire holding tufts of bristles. One of the brushes, [8, is somewhat smaller than the other, l9, and each brush is mounted on a weighted block, as shown at 26 and 2| respectively, said blocks being supported in a suitable frame 22 and hinged together by projecting ears and a hinge pin at 23 so that when one brush is laterally tilted the other is likewise tilted in the opposite direction (see Fig. 5). As shown the said brushes mesh when in normal position.

In practice according to the construction shown on Fig. 3, if a tumbler is pressed in inverted position fully down on one of the said brushes to enter the tumbler the effect is to slightly separate the brushes with one brush bearing on the interior wall of the tumbler and the other bearing on the exterior wall thereof. In all cases the brush selected for scrubbing is such that when the tumbler to be scrubbed is pressed down, the brush should be somewhat crowded in the tumbler to effect good scrubbing contact.

Upon rotating the table while firmly holding the tumbler from rotation in the hand of the operator the effect is to cause the brushes to scrub both the interior and exterior surfaces of the tumbler. When the tumbler is removed from the brush the weighted members in which they are rooted automatically restore the brushes to closed or meshed relation.

Referring now to the set or group of three brushes 25, 26 and 27, as shown in the plan view Fig. 3, the brushes 25 and 26 are rooted in a single block 28. The brush 25 is the smaller of the two and of cylindrical form while the brush 26 is of loop form. The brush 25 is rooted centrally at 2511 in the said block 28 and the stems of the loop-brush 26 are rooted at two points 26 at opposite sides of the root 25 as indicated in Fig. 7. The cylindrical brush 25 therefore stands at a meshing slant to the loop brush 26, as shown in Fig. 1. The block 28 is supported by a plate 29 on the upper surface of the table in a radial slot therein, said plate 29 being provided with slots 30, 30, through which set screws are passed to secure said brushes 25 and 2'6 in adjusted position in relation to the third brush 2?.

The third brush 2'! is rooted and supported, as seen in Figs. 1 and 7, in a weighting member or block 33 hinged at 3| between parallel bracket arms 32 secured to the upper side of the rotatable table and extend at the lower side of the said table so that after a piece of the drinking ware has been placed on said brush 27 it is internally and externally scrubbed in the same manner and with the same effect as hereinbefore described in respect to that operation with the brushes l8 and 19. The three brushes are adapted for three different diameters of drinking vessels.

At the right hand side of Figs. 1 and 3 there is shown a device for scrubbing the exterior of the bottom of a piece of ware such, for example, a beer mug. In this construction there is a circular brush mounted stationarily on four posts 36, the latter being supported on a plate 31 that in turn is secured to a central tube 38 fixed in the rotatable table. The other brush 39 of this device is shown as of pine-tree form having a trunk or stem 3E: that is reciprocable vertically in the said tube 38. In order that said brush 39 shall exert pressure on the bottom of the mug, especially if it be concaved considerably upward, the trunk or stem of this brush has a pin 40 extended through it with a coil spring 4| connecting each projecting end of the said pin with the plate 37 so as to hold the brush yieldingly upward with sufficient force satisfactorily to scrub the mugs bottom when pressed downward on said brush. When the brush 39 is thus pressed down with a mug or other article to be scrubbed at its bottom externally the end of the mug is at the same time encircled by the ring brush 35 so that when the article to be cleaned is held firmly in the hand and the table rotated, the said brushes exert a scrubbing effect, due to the relative rotation of the brushes in the ware, in the manner hereinbefore first described, except that the scrubbing action is in both horizontal and vertical planes.

It is, of course, desirable that water or other cleaning fluid be used in connection with the operation of the brushes, and that the apparatus be placed in a tub into which water or a sterile solution can be supplied. In Fig. l is illustrated, in broken lines, at 88 a tub in which the apparatus is placed, the said tub having an overflow hose connection at El, and a drain or clean out at 62. The said drain includes an ordinary han dle 63 to operate an ordinary valve to control the drain and the overflow hose connection 6| provides for the contingency of neglect to cut off Water after work is done. It is also desirable that the water or solution be directed into the region where the scrubbing is done and onto the brushes and the surfaces scrubbed and the supply of water controlled as to time of its application.

The means for supplying such water consists of a pipe connected at its discharge end with the chamber ll, there being in said pipe a casing 46 containing a valve for opening and closing said pipe and a spring 41 for automatically moving said valve to closing position. Said valve has a stem 48 projecting from the casing; and hinged at 49 near the valve casing is an arm 50 having at its free end a roller 5| in constant contact with the eccentric or cam l4 that rotates with the sleeve and table [5. The pipe 52 that leads to the valve casing is extended to be connected with any suitable source of water under pressure. If desired a sterilizing agent can be supplied to the water in the tub.

There are as many of the pipes I! as there are pairs and groups of the brushes, in this case there being three, said pipes being extended upward through small holes in the table in which said pipes fit so that the pipes are held steadily in proper relation to the brushes.

According to the construction shown the water is substantially simultaneously discharged onto practically all the groups of brushes and correspondingly cut off according to the position of the valve, the latter being controlled by the position of the eccentric or cam. By reason of this construction the water may be cut off when the washing of a piece of ware has been completed, and the brushes determined upon for application of another and perhaps different size of ware in the interval when the water is cut off. It will be understood that in applying a piece of hollow ware of the type of drinking glasses to a brush the pressure of the operators hand is first downward onto an appropriate brush and then in a lateral direction to cause rotation of the table and that this rotation of the table while the Ware is held without substantially turning the ware on its axis causes relative rotation of the brushes in respect to the axis of the ware. In other words if the ware were not held the brushes would not rotate with respect to the axis and surfaces of the ware.

The forms of the parts can be changed without departing from the gist of the invention as claimed.

What I claim is:

l. A drinking ware washing apparatus including a horizontal freely rotatable table, two brushes secured to the table in proximity to each other in an erect and meshing position and at points offset from the axis of rotation of the said table with the axis of said brushes both laterally remote from the axis of rotation of the table and between which brushes the wall of the drinking ware can be inserted, whereby when the table is rotated by pressure of the hand on the ware without substantial rotation of the ware a scrubbing action on the ware is effected.

2. A drinking ware washing apparatus including a horizontal freely rotatable table, two brushes secured to the table in proximity to each other in an erect and meshing position and at points offset from the axis of rotation of the said table with the axis of said brushes both laterally remote from the axis of rotation of the table and between which brushes the wall of the drinking ware can be inserted whereby when the table is I rotated by pressure of the hand on the ware without substantial rotation of the ware a scrubbing action on the ware is effected, and means connected with said table whereby a spray of water can be applied to said brushes during the rotation of said table.

3. A drinking ware washing apparatus including a horizontal freely rotatable table, two brushes secured to the table in proximity to each other in an erect and meshing position and at points offset from the axis of rotation of the said table with the axis of said brushes both laterally remote from the axis of rotation of the table and between which brushes the wall of the drinking ware can be inserted whereby when the table is rotated by pressure of the hand on the ware without substantial rotation of the ware a scrubbing action on the ware is effected, and means connected with said table whereby a spray of water can be applied to said brushes during a portion of the rotation of said table.
