SCRUBBING MACHINE 2 Sheets-Sheet l Filed June 29, 1927 April 1, 1930. H. o. BoUTwELL SGRUBBING MACHINE Filed June 29. 1927 2 Sheets-Sheet 2 HTTORN EY Patented Apr. 1, 1930 PATENT OFFICE mail o. Bon'rwnnr., or Los ANGELES, CALIFORNIA scnUBBiNG MAcnrNE Application led June 29,

My invention is a scrubbing machine having a water tank, scrubbing brushes and a pump for withdrawing the water from the floor to the used water tank.

An object of my invention is the construction of a scrubbing machine in which the machine carries a tank of fresh water for scrubbing. The water is discharged and the floor is scrubbed by scrubbing brushes. The dirty water is then sucked up from the floor by a pump type of device and discharged into a used water tank.

Another object of my invention is in a scrubbing machine of thecharacter above described having double walls at the front and back of the machine, through which the dirty water may be sucked by a suction pump and deposited in the used or dirty water tank.

Another object of my invention is to operate the scrubbing machine by an electric motor contained in the machine, the machine being mounted on the supporting wheels and also having the pump operated -by the motor.

Another object of my invention is having the scrubbing brushes rotating on a horizontal axis, and also a plurality of vertical brushes positioned adjacentl the corners of the scrubbing machine to scrub into corners.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a plan view of my machine partly broken away.

Fig. 2 is a compound vertical longitudinal 35 section, the planes of section being takenon the lines 2-2 of Figure 1 in the direction of the arrows.

Fig. 3 is a side .elevation of my machine taken in the direction of the arrow 3 of Figure 1.

Fig-4 is an opposite side elevation taken in the direction of the arrow 4 of Figure 1. Fig. 5 is a vertical transverse section on the line 5--5 of Figure 2 in the direction of the arrows.

The carriage of my scrubber comprises a suitable fixed frame preferably, in the form of a casting 11 and a pair of forward wheels 12 are mounted supported from said casting, and a rear adjustable wheel 13 is also se- 1927. Serial No. 202,235.

cured to the castin The rear part 14 of the casting preferab y houses an electric motor, and in the forward part 15 there is a suction pump operated from the motor. This pump may be of any suitable character, and 55 as it does not f orm an immediate part of my invention, is not illustrated or describedin detail.

The scrubbing chamber is designated generally by the numeral 16 and comprises a front wall 17, a rear wall 18 and opposite side walls 19. A main scrubbing brush 20 is mounted on a transverse shaft 21 which is mounted in journals22 on the' side walls, and this shaft has a` large gear 23 preferably at each end. Each large gear meshes with a driving gear 24 mounted on a drive shaft 25 mounted in journals 26 on the side walls. This shaft has a worm wheel 27 driven. by a worm 28 on a longitudinal shaft 29 which is mounted in journals 30 on the front and back walls. This shaft extends through the back wall and is connected in any suitable manner tothe electric motor, and driven either by the gearing or directly lfrom such motor. l

A Apair of vertical brushes 31 are each mounted on a vertical shaft 32 supported in suitable journals 33 preferably connected to the side walls, and at the'upper end of each vertical shaft there isa beveled gear 34 which mesheswith a beveled gear 35 on a transverse shaft 36, driven by a wormwheel 37 meshing with a worm 38 on the longitudinal shaft 29; In this manner the horizontal and vertical scrubbing brushes are' simultaneously rotated. The horizontal brush does the main scrubbing operation and the vertical brushes operate principally in scrubbing the corners of a room or lthe places inaccessible to the horizontal brush.

The water system is substantially as follows: A clear water storage tank 39 is mounted on a .suitable base 40 which'is positioned on top of the scrubbing chamber. The tank 95 or reservoir illustrated is rectangular and has a removable top 41. The water is fed out of the discharge pipe 42 on the rear side of the storage tank, passes through a control valve 43 through an elbow connection 44 to 100 a forwardly extending feed pipe 45, and from thence is led into a distribution pipe 46 having a series of spray outlets 47.y This latter pipe is supported on brackets 48 and positioned in the scrubbing chamber above the main scrubbing brush 20.

The suction system for the water comprises a forward suction chamber 49 which is formedfby the-front wall 17 and a front false wall 50 spaced apart, there being a rubber squeegee 51 secured to the lower edge of the front wall. A rear suction chamber 52 is formed by the rear wall 18 and the rear false wall 53. There is also a squeegee 54 at the base of the rear wall. This rear wall has a suitable opening 55 leading into the pump chamber. The front and the back suction chambers 49 and 52 are connectedby one or more longitudinal pipes 56.

The water after being taken through the pump is discharged through a discharge pipe 57, this -being bent'to form an elbow, and by means of a reduced coupling 58 this is connected to a rubber hose 59, the hose being attached to a hose coupling 60 on the top of a used or dirty water tank 61. The top of this tank is attached by a clamp 62. This latter Y draws the water as tank is preferably rectangular and is mounted on a bracket 63 extending rearwardly from the rear wall 18. -Both of the tanks are removable to allow cleansing, and in order to operate the machine, a handle 64 is connected front, back and side walls, the front Wall having a suction chamber open at the bottom,

a plurality of scrubbing brushes mounted on Vertical axes adjacent the front wall and at the corners of the scrubbing chamber, means to supply water to the brushes, and a -pump gperatively connected to the suction'cham- In testimony whereof I have signed my name to this specification.

.HARRY O. BOUTWELL.

to the frame work and forms the means for connecting the electric wires to the motor.

From the above description it will be seen that water is sprayed downwardly from the pipe 46 on to the large brush, and this water would preferably be charged with a cleansing compound such as soap or other suitable material. The scrubbing action of the horizontal and the vertical brushes thoroughly cleanses the fioor, the vertical brushes working into the corners, and on account of the squeegees 51 and 54 on the front and back walls, the

rubber strips 65 on the side walls, the water is prevented from being forced under the walls of the scrubbing chamber. The pump well as a considerable amount of the air upwardly through the suction chambers 49 and-52. AThis action of the pump sucks'air underneath the Walls of the scrubbing chamber and functions in this manner to prevent the water from escaping. The mixture of water and air lifted by the pump is discharged into the dirty water tank above mentioned, and the air escapes through vents in the cover of this tank.

It will thus be seen that I have developed a machine which carries its own water supply, and not only scrubs the floor, but removes the surplus water from the fioor, and thus practically dries the ioor as much as is necessary.

Various changes may-be made in the principles of my invention without departing Aeo
