3Claims. (o1.2s5-9o) 4 through the flange I8 and engaging the'inner This invention relates to cleaning machines and, more particularly, to a construction for filling such machines with cleaning liquid.

A primary object of this invention is the provision of a filling device for cleaning machines which is very easily attached and detached and which includes a nozzle directed in substantially the same direction as, the hose to which it is a.t tached, so that it can be conveniently used for purposes other than filling the cleaning machine.

Another object of the invention is to provide a cleaning machine having a filler opening and a cooperating nozzle so constructed as to hold the nozzle in place during filling.

Still another object of the invention is to provide a cleaning machine including a cylindrical tub having a'filling opening in its side wall and a-nozzle arranged to discharge cleanin liquid tangentially into the tub. 1

Another object is to provide a filling nozzle connected to a supply of temperature-adjustable water, the nozzle leaving an exposed metal portion in good heat conducting contact with the water and readily contacted by the operator's hand, by means of which the temperature of the water entering the tub can be readily determined within necessary limits.

The above and other objects, advantages and novel features of the invention will be apparent from the following description when read in connection with the accompanying drawing, in which:

Figure 1 is a vperspective 'view of a cleaning machine embodying the invention with parts broken away;

Figure 2 is an enlarged vertical section through the flller opening with the nozzle in place; and Figure 3 is a section on the line 3-3 oi Figure v The illustrated cleaning machine comprises a cylindrical tub I 0 supported on a base I 2 with side of the tub to hold the grommet in place.

Inits central portion the grommet is provided with an elongated slot 25 as best seen in-Figure 3, whose long sides .are defined by arcuately curved wall portions 26, the cross section of the grommet in a plane normal to the side wall of the slot having the shape of the cross section of an anchor ring. The wall portions preferably extend inwardly through an arc of substantially 90 from the throat of the slot and may, if desired, be carried outwardly past the throat to.

form a flaring mouth.

The tub is adapted to be filled by a city water supply or the like, indicated generally at 28, through a flexible hose 30. At its outer end the hose 30 carries a nozzle 32 formed of a metal conduit bent through substantially 90". At its discharge end the conduit is flattened as at 34 to conform in section to the shape of the slot in the grommet and is bent through an arc of substantially-90. To'flll the tub the nozzle portion 34 is inserted through the slot in the grommet 20 and is swungaroundv to the position shown in Figure 2 with the curved portion 34 lying against one of the like arcuate walls 6 and discharging substantially tangentially of the 'itub. In this position the nozzle portion 3| serves to lock the nozzle in the grommet, so that it will remain in place without the necessity of any external holding means during filling of the tub. It also will its axis horizontal and having an opening in flanged portion 22 adapted to fit over the flange l8 and an enlarged inner portion 24 extendin be noted that the nozzle discharges tangentially between the tub'and the drum so as to flll the tub rapidly with a minimum of splashing.

While one embodiment of the invention has been shown and described in detail, it will be understood that this is illustrative only and is not intended as a definition of the scope of the in.- vention, reference being had for this purpose to the appended claims. 5

What is claimed is:

1. In combination, a fluid receiving tank having an opening through its wall, a rubber grommet secured in the opening, said grommet having a slot-shaped opening therethrough, one cross section of the grommet having the interior shape of the interior of an anchor ring, and a removable nozzlefitting said grommet opening and having a portion lying against the inner part of the grommet atone side of the grommet opening to prevent the removal of the nozzle byya-i'oroeapplied in line with the opening through the grommet, said nozzle being readily removable from the grommet by rotation on an axis lying within the grommet and parallel with the slot-shaped opening therein and parallel with the tank wall in which the grommet is secured.

2. In combination, a fluid receiving tank having' an opening therein, a flexible grommet fitted into said opening and having a portion overlying and underlying the tank wall about the opening therein, said grommet having a passage therethrough elongated in the plane of the tank wall and extending from without to within the moval of the nozzle by rotating it about the center of said circular part of said grommet.

3. A flexible grommet having an anchor-ring shaped cross section, a nozzle of a size to fit the opening through the grommet, the discharge end of the nozzle being curved to conform to the inner face of the grommet and discharging at substantially right angles to the opening through the grommet, the portion of the nozzle external of the grommet extending substantially parallel to the line of discharge from the nozzle but in the opposite direction, and a flexible hose attached to the external portion of the nozzle for assisting in preventing the nozzle from accidentally rotating in the grommet to a position in which the discharge end of the nozzle falls in alinement with the opening through the grommet.
