i AIR-SUCTION CLEANING APPARATUS.

Specification of Letters Patent.

Patented Aug. 10, 1909.

Application led October 3, 1908. Serial No. 456,976.

Tov all who/m. it may. concern:

- Be it known that I, ARTHUR H. SQULER, a citizen of the United States, residing at Philadelphia, in the' county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Air-Suction Cleaning Apparatus, of which the followingf'is a specification.

My inventlon relates to -improvements in air suction cleaning apparatus, and more particularly to an improved portable mechanism designed particularly for'wet cleaning, such as scrubbing floors and the like, bulit may also be used for dry cleaning'as we An object of the invention is to provide improvements of this character Which will, in wet cleaning, supply just the roper amount of water to the scrubbing evice, and which can be operated to remove all the water from thei'loor at the propertime.

A further object isto so construct an apparatus that in dry cleaning, Water will be commingled with the dust laden air, allaying all dust and precipitating it to the bot.

tom` of the receiving or suction tank, and preventing the dust passing to the pump.

A further object is to so construct the several parts, that the water accumulated Iin the receiving tank can be readily 'returned to the water chamber, and when the water therein becomes dirty can be ejected and clean water drawn in its place without undue loss of time.

With these and other objects in view the invention consists in certain novel features of construction, combinations and arrange' ments of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1, isaview partly in section illustrating my improvements. Fig. 2, is an enlarged view in longitudinal section of the scrubbing device on the line of Fig. 2. Fig. 3', is a viewin section at right angles'to Fig. 2, and Fig. 4, is a view of a modiied construction of tank.

1 represents a receiving or suction tank or chamber vsecured upon the open upper end of a .water chamber 2.' The bottom 3 of tank 1 etfectually closes tank 2, forming in elect, a single tank divided by. ahorizontal partition into upper and lower chambers. A pipe 4 connects the upperportion 'of chamber 1 with a suitable pump 5 shown small pi e or hose 11 connects with the cock or va ve 22, and extends to the scrubbing device, as will more fully hereinafter appear. This cock or valve 22 is normally open and is only closed when pipe or hose 11 is to be disconnected. y

A hoseL connects pipe 6 with a metal ipe 6? having a nozzle 6 at its end and the latter projects into the center of a brush 12. An apron 13 is provided around thc l brush and another apron 14 about the nozzle 6c, the bristles floor until brush.

The hose or pipe 11 as above stated, eX- tends to the brush and preferably divides at the brush to discharge the Water in the opposite ends thereof and more evenly distribute the same. A preferred and economical structure is to proyide a double woven hose such as illustrated connecting the tank and handle which is formed by pipe 6b. The larger hose 6a serves as a suction pipe nd he smaller hose 11 conveys Water to the rus apron 14 being shorter than the o the brush so'as not to touch the unusual pressure is put upon the

Valves

15 and 16 respectively arel provided I inthe pipes or passages 6b and 11 in convenient reach of the operator during the scrubbing operation,y so that he can control the passage of water from and to the tanks as will be explained.

A .springlpressed double acting valve 17 normally closes an opening in the bottom 3 of the tankll, and hence normally prevents any water in tank 1 from passing to tank 2, and a vent 18 of any preferred construction is located at the upper portion of tank or chamber 2 to compensate for Water drawn therefrom and prevent a vacuum in the chamber 2.l v

In themodication illustrated, in Fig. 4, I show an 'ordinary globe valve 20 normally closing the passage between tanks' l and 2,

this valve being hand operated from the outside of the tank, and in this modified construction l may employ a safety valve 21 in pipe l leading to the ump.

The operation of my improvements is as follows: ln 'the `scrubbing operation, the

mlve J is turned to close communication between the

pipes

6 and 7, butpermit a Afree passage through 6 and 6 into tank 1, the valve 22 is open and valve 10 preferably closed. The valve 18 is open, and when the? pump 5 begins to create a. suction or partial scrubbing device. The proper suction can be controlled by turning the valvel so as to draw just the proper amount of Water to' the scrubbing device.

When the floor isv thoroughly scrubbed by manipulating the j scrubbing device over the same, the operator 2. closes valve 16 to shut ofi' the Water, and

then while moving the scrubbing device over the floor, he presses down upon the lSame until the apron 14 rubs on the door, and thesuction of airA under the apron 14, and through the space inclosed by the apron 14, will be so great that the dirty Water will be sucked through the

pipes

6c, 6", 6, and 6v into tank 1. When the water accumulates in tank 1 and it is desired to transfer the same to tank 2, the valve 15will be closed,

The pump o yclear water.

and valve 9 will remain in a position to revent communication between pipes 6 an 7.

then exerts such a suction in tank 1, that valve 17 wil'l be drawn upward to permit the water'to pass into tank 2. To blow the dirty water out of tank 2, valves 18 and 22 are closed and valve 10 turned so as to allow free passage through pipe f?.

Valve 9 is turned so as to allow a free assage between

pipes

7 and 6, but to c ose pipeiG, andvalve 15 is Valsoopened. When thevpump is reversed to, exert ressure in tank 1, it will vopen valve 17 an allow the air to exert a pressure on the dirty water in tank 2, to` force the water through the

pipes

7, 6a, 6", and 6c into the sewer, or else-A where, over which the scrubbing device is placed. IVhen the dirty water is forced out, the operator leaves the 'valvesexactly as they are, and places the scrubbing device in The 'pump is reversed and sucks vthe clear water through

pipes

6, 6h and 6, into tank 2,the valve 9`being turned so as to prevent the water being `drawn directly into tank 1, but compelling it to be drawn down pipe 7 into tank 2.

During the dry `cleaning yoperation in which the water is utilized only as a clean. ing medium for the air, valve 18 is opened, valve 10 is positioned to close pipe 8, but leave the pipe 7 open, the valve 9 1s turned so as to open communication between the

pipes

6, 6 and 7, and a suitable cleansing nozzle of any character is connected with the pipe 6. When the pump is o erated to exert a suction in tank 1, the ust-laden air will be drawn through

pipes

6 and 6 and across the upper end of pipe 7, causin the water to be drawn up pipe 7 and commingle with the dust-laden air and pass with it into the tank l, where the particles of water which have taken up the dust in the air, will be precipitated into the bottom of tank 1 and the cleansed air will pass to the pump.

Slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at libert to make such changes and alterations as airly fall within the spirit and scope of my invention. 4 Having thus described my invention wha I claim as new and desire to secure by L etters Patent is: v.
