MOPPING DEVICE.

Application tiled Detener 30, 1922.

f/"o all whom t may conce/ra Be it known that l, LAWRENCE B. Wan Ton, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mopping Devices: and l do declare the following to be a full, clear. and exact description of'the invention, such as will enable others skilled in the art to which it appertains to malte and use the same, reference being had to the accompanying drawings and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to a floor cleaning machine and the primary object is to provide a machine for cleaning floors which may employ a mop and if desired, brushes, so that the floor can be conveniently scrubbed, there being means provided for supplying water to the mop for the initial scrubbing and a wringer is also provided for wringing out the water so that the mop can finally pass over the floor to take up the 5 excess moisture.

The mop will be driven so that it will pass over the floor first for taking off the initial dirt and then for effect-ing the final mopping, there being provision made whereby brushes can act on the floor between the two mopping operations.

The novel construction of the invention will be apparent by reference tof the following description in connection with the accompanying drawings, in which- Fig. 1 is a vertical, longitudinal, sectional view through floor cleaning machine constructed in accordance with my invention.

Fig. 2 is a cross sectional viewon the line 2*2 of Fig. 1, and

Fig. 3 is an enlarged view showing one of the mop elements co-operating with the mop chain.

Referring now to the drawings by numerals of reference:

'l designates a casing supported a suitable distance above the floor by the

wheels

2 and 3. The casing carries a suds reservoir or tank 4, through which the mop may pass to take up the suds before it passes over the floor, the mop being adapted to return to the tank for rinsing purposes before passing through a wringer, from which it then passes through the housing to again contact with the loor to take up the moisture.

Serial No. 597,799.

The tank can be supported in any suitable way and in any suitable position, for example, as shown in Fig. 1.

The casing 1 is: provide-d with a handle 5 by means of which the casing may be moved to and fro over the licor. lt is the purpose of my invention to have the mop driven mechanically and to this end I have provided on the casing 1 a motor 6, shown as an electric motor, adapted to receive current from any suitable source and on the pulley 7 on the drive shaft of the motor is a belt 3 which. drives a pulley S) on a shaft 10' which extends through the casing. There is a small pulley 11 on the shaft 1() around which passes a belt 12, also passing around a pulley 13 on the` brush shaft 14. The shaft 14 carries a brush 15 (see Figs. 'l and 2). On the shaft 14 is another pulley 16 around which passes a belt 17 to drive the shaft 18 for the brush 19.

The mop is in the form of an endless belt consisting of the two

chains

20 and 21, driven by

sprockets

22 and 23 on the shaft 10. The chains engage the

teeth

24 and 25 on the end of roller spindles 26. The roller spindles carry the mop cloths 27 so that the mopping elements which assist in making up the belt are of cylindrically arranged fabrics.

The belt consisting of the chains and the mop elements being driven from the shaft 10 is guided on the guide rails 28 which, intermediate the ends of the tank, dip down into the reservoir 4 in the form of a half loop, as indicated at 29. The major portion of the guides are outside the tank how ever.

Viewing the drawing in Fig. 1, the left hand side of the tank is the mop-diseharging end of the tank; that is, the mop leaves the tank from that end and passes over the guide portions 30, guided downwardly by the vertical guides 31 and across the short bottom guide 32 so that the mop elements 100 will contact with the floor; then the mop elements pass up on the vertical guides 33 and into the tank on the half loop-shaped guides 34 and then upwardly to a wringer 35, which consists of wringer rollers, one set 105 36 of which may be rigid and the other set 37 of which may be spring-actuated by being carried on the plate 37, pivoted at 38 and having an arm 39 which is engaged by a tension spring 40, one end of which is fas- 110 tened to the casing at 4l. 1When the mop passes through the wringera it is then guided downwardly by the vertical guide 4t2 and across the bottom guide L3 where it will come in contact with the floor practically devoid of moisture so that it will take up any excess moisture from the floor. Then the mop belt passes upwardly along the guide #l-#l and back into the receptacle or suds reservoir.

Between the two mop portions guided by the guides 32 and i3 are the scrubbing brushes l5 and 19, which will rotate to loosen the dirt moistened by the mop which has previously passed over it so that there can be a scrubbing action on the floor, the

necessary water for the brushes having been supplied by the portion of the mop which initially comes into contact with the floor.

The mop belt is caused to take the downward dip into the suds by the idler 45.

The belt, being driven by the motor, will operate continuously while the device as a whole is moved back and forth over the sur'- face to be cleaned and there will be presented to the surface mop elements which will contain considerable moisture so that the wet part of the mop may iirst pass over the floor. Then the ioor may be scrubbed by the brushes, and finally the drying portion of the mop will take up the excess moisture. All this can be done in a mechanical way without any undue manual exertion.

The mop elements themselves may consist of cylinders or shafts with fabric wound about them, or they may consist of shafts with tubular fabrics with packing between the fabrics and the shafts. The mop elements should possess sufficient yieldabilitys however7 to allow them to pass through the wringer so that the excess moisture can be pressed out of them. y Y

From the foregoing it will be apparent that the device is simple in construction, that it may be conveniently operated from the motor carried by the casing, and that access may be had to the interior of the casing through the medium of a hinged door or cover 46.

That I claim and ters-Patent is:

floorl scrubbing machine comprising a carriage including a hollow casing, open at the bottom and closed at the top, a water receptacle within the casing, the ends of the desire to secure by Letwater receptacle being spaced from the endsV of the casing to provide vertical end spaces, a traveling endless mop carrying belt having upper and lower flights, means for guiding the upper and lower flights through the water' receptacle, the endless belt projecting through the vertical spaces and below the casing so that the belt will contact with the floor during its travel at each end of the casing, means for driving the belt and a wringer within the casing through which the belt passes.

In testimony whereof I aiiix my signature.
