Application August 12,

3 Claims.

This invention relates to cleaning equipment, and more particularly to combined washing and wringing devices for treating, cleaning, and polishing elements, such as chamois and the like cloths, which are sometimes employed for cleaning Windshields and polishing car bodies in automobile service stations, the principal objects of the invention being to provide a convenient, relatively economical and highly efficient apparatus of the character noted.

Other objects of the invention are to provide a self-contained washing and wringing device in which the wringing device is motor driven; to provide for energizing the wringing elements of the device at such times as it is desired that the apparatus be operated; to so arrange the apparatus that it may be operated by the foot of the operator, thus leaving the hands of the operator free to manipulate devices being washed and wrung; to provide a unit that is attractive in appearance and that is readily portable for facilitating the service of cars ina service station; to preclude wrapping of the cleaned and wrung devices about the wringing elements of the apparatus; to provide for presenting the wrung cleaning devices in convenient relation to the apparatus for facilitating handling thereof by an operator; to provide for encasing the driving parts or elements of the apparatus relative to the wring-. ing elements of the apparatus; to provide for adjusting the wringing and wrapping precluding elements of the apparatus; to provide for servicing the driving elements of the apparatus; and to provide improved elements and arrangements thereof in cleaning equipment apparatus of the character and for the purposes noted.

In accomplishing these and other objects of the present invention, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 6 is a diagrammatic view tern for energizing present cleaning equipment.

Referring more in detail to the drawings:

I generally designates cleaning equipment embodying the present invention, which preferably consists of a horizontally arranged base plate 2 that is preferably provided with swivelled casters or the like 3 at the corners and on the bottom surface thereof.

An end wall l is vertically arranged adjacent the end 5 of the base plate, the end wall preferably being of a width less than the Width of the base plate toprovide platforms or ledges 6 and 'l atopposite sides of the base plate. sidewalls 8 and 9 extend from the side edges of the end wall 4 forwardly approximately to the end Ill of thebase plate and terminate in inwardly directed flanges H and ii that are preferably of less length or height than the end wall 4. The lower edges of the side and end walls are turned inwardly to provide supporting flanges l3, l4 and I5 that may be suitably secured to the base plate 2 in order to form a rigid to more clearly illusof awiring systo overlie the flanges H and the panel and flanges apertures for receiving fastening which the panel l2 of the side walls,

It may be removably secured to theside walls and form an enclosure or compartment [8 within the walls.

A bottom forming plate IQ for a tank generally designated 20 is horizontally arranged between the end and side walls 4, 8 and 9, the plate if! provided with a downwardlypreferably being turned flange 2| that is suitably secured, as by welding, to the side and end walls above noted.

The plate I9 is also preferably arranged approxiplane of the panel l6 and within the flanges II and I2 of the side walls to form an end wall 22.

for the tank 20.

The upper portion of opposite wall for the tank, and the upper pore tions of the side walls 8 and fl form the side walls for the tank 20. The end wall 22 of the tank'is also curved rearwardly, preferably at approxie mately the upper end of the flanges I l and I2, as

prefparts thereof being the driving elements of the mounting for the walls. It designates a panel that is of a size and shapebeing provided with aligned devices ll by the end wall mm the erably downwardly and backwardly turned lip 26 adjacent one end of the tank.

The upper edges of the side and end walls of the tank are preferably rolled outwardly, as indicated at 21, to provide a relatively blunt edge to protect operators working about the apparatus and enhance the appearance of the equipment.

With the construction thus far described, it is apparent that equipment is provided that includes a lower accessible compartment l8 and an upper substantially open tank 29.

It is contemplated that water or other cleaning liquid 30 is to be supplied the tank 20 to a suitable level and a drain opening 3| is provided in the bottom wall l9 of the tank which opens into an outlet duct 32 arranged in the compartment l8 and extending through the bottom wall thereof, as at 33, for disposing of liquids in the tank, a suitable plug or discharge control 34 being provided for that purpose.

The bearing blocks 35 and 36 comprise side flanges 40 and M at their upper ends, the outer edges of the side flanges being connected by a web 42 to form channels 43 for slidably mounting approximate surface, contact therewith.

Assuming that cleaning devices such as ois skins or cloths have been washed in the tank 20, it is contemplated A belt 56 that is mounted on the pulley 55 connects with a pulley 51 that is preferably of reduced size, the pulley 57 being mounted at one end 58 of a drive arranged in and pro- Jecting from the cabinet or compartment l8.

The switch 7d preferably comprises a housing having bearing bosses that are secured to the base plate 2 as by a fastening device 16, one of the ledges 6 and? of the base plate being a d mirably suited for this purpose. An insulated contact I? is mounted in one of the walls of the switch housing and is arranged for electrical connection with the line 73, as indicated at 18. A spring switch element 19 on the ing. The contact'tiii is connected, as at 8|, with the terminal of a current conducting the other lead-in line wiring system for energizing the motor 59.

depression of which forces the head of the rod' 85 into engagement with the contact 19 to spring the contact into current conducting engagement with the contact 80 and complete the circuit through the lines 13 and 82 to the motor.

The motor lead-in line l2 being connected with a source of current supply, the motor is energized to rotate the pulley El and through the belt 66 rotate the pulley 65. The shaft 59 is thus rotated to cause the pulley 51 to move the belt 56 and rotate the pulley 55 which rotates the wringer roller 39. Frictional engagement between the wringer roller 39, the chamois skin and the wringer roller 41 causes the chamois skin to be rolled through between the wringer rollers and wrung out to a substantially dry condition. The tendency of the chamois skin to stick to the wringer roller 41 and wind upon the same is overcome by the plate the lower edge of which separates the chamois skin from the roller 41 and allows the same to drop upon the platform 92. As a matter of practice, more than one chamois skin or the like may be wrung out and chamois skins succeeding the first may be left upon the platform 92 in a convenient position to be picked up by the operator when the first chamois skin has become soiled.

If two or more skins are wrung out together, it is sometimes desirable to adjust the wringer rollers vertically relative to each other in which case the adjusting device 59 may be manipulated to raise the wringer roller 41 relative to the roller 39 and provide more space between the rollers through which the chamois skins may more easily pass. When the chamois skins have served their purpose, they may be returned to the tank for rewashing and reuse as and when desired. 5 It is apparent, therefore, that the present invention provides a convenient, economical and. eflicient cleaning apparatus that is attractive in appearance, easily moved from place to place, readily manipulated, simple in construction and easily accessible for necessary repairs.

What I claim and desire to secure by Letters Patent is:

1. In cleaning equipment of the character described, a tank having side and end walls, one of said walls having an inwardly turned upper edge, wringing apparatus mounted on said tank, and a platform arranged adjacent said wringing apparatus for receiving devices wrung thereby, an edge of said platform being arranged adjacent the inwardly turned upper edge of the wall of said tank to form a limited space to allow application of devices to be cleaned to the tank.

2. In cleaning equipment of the character described, a base plate, connected side walls and an end wall arranged in vertical relation to said base plate, a horizontal partition arranged intermediately the height of said side and end walls to define a compartment, a panel removably mounted on said base plate and side walls to provide access to said compartment and forming another end wall, and an extension on said horizontal partition having an inwardly curved upper end cooperative with said partition and walls to form a tank.

3. In cleaning equipment of the character described, a base plate, walls arranged in vertical relation to said base plate, certain of said walls having inturned flanges, a horizontal partition arranged intermediately of the height of said walls to define a compartment, and an extension on said horizontal partition having an inwardly curved upper end cooperative with the inturned flanges on the walls to form a tank.
