WILLIAM BAKER, OF CINCINNATI, OHIO.

soRU B BRUSH.

To all whom it may concern:

Be it known that WILLIAM BAKER, a citi- Zen of the United States of America, residing at Cincinnati, in the county of Hamilton and State of Ohio, has invented new and useful Improvements in Scrub Brushes, of which the following is a specification.

At present, a bucket and sponge are used. for scrubbing floors and walls and especially those of railroad cars, and to avoid this tedious method, it is the purpose of the present invention to provide, in a scrub brush, a construction for keeping the brush supplied with water and soap, the brush having a handle whereby the operator may easily manipulate the brush and thereby insure reaching all parts of the surfaces being scrubbed.

Another purpose is to provide a pair of.

brushes rigidly connected, with a perforated v supply pipe for the Water mounted between certain of the bristles of the brush, in con-,

junction with liquid soap fountains or containers having perforations registering with perforations in thebacks of the brushes to keep the bristles thoroughly supplied with soa 3.

s till another purpose is the provision of means for retaining the fountains or containers on the backs or wood portions of the brushes. r

A further purpose is the provision of means forrigidlysecuring the handle to and connecting the backs of the brushes to insure rigidity, th perforated pipe further insuring strength and durability.

A still further purpose is to provide a scrub brush of this design wherein a. metallic tubular handle is connected to the brush for operating the same, together with means for connecting a water supply hose to said handle to keep the brush supplied with water.

It is to be understood that the particulars herein given are in no way limitative and that, while still keeping within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus according to the circumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a plan view of the improved scrub brush constructed in accordance with the invention.

Figure 2 is a longitudinal: sectional view through the twosections of the brush.

Figure 3 is a plan view of the brush.

Figured is a transversesectional view on line 44 of Figure 2.

Figure 5 is a plan view of the brush, showing the tubular handle which is adaptedfor connection with a hose which supplies water to the brush.

Referring to the drawings, 1 and 2 designate the two sections of the brush. The backs of the sections may be constructed of any suitable material, preferably wood or metal, and are provided with rows of bristles 3. The backs of the sections of the brush between the rows of bristles are perforated, as shown at 4, and mounted upon the backsare fountains; 5 for receiving liquid soap. The fountains are rectangular in cross section and have. their bottoms provided with perforations 6 which register with perforations 4 in the backs of the sections of the brush.

The fountains seat, in depressed recesses 7 in the backs of the brush sections, there being a filler of rubber in the bottoms of the recesses to prevent leakage. Suitable U- shaped stays or straps8 straddle the fountains. the arms of the straps passing through openings in the backs of the brush sections,

there being'suitable nuts 9 threaded upon the to hold the straps securely in position and retain the fountains clamped to the backs of the brush sections. The fountains are provided with-filling openings 10 which are closed by caps 11;

As shown in Figures .1 to 4, a handle 12 is provided which engages a socket 13 of a handle coupling device 14c. This device has lateral arms 15 which are secured by screws or the like 16 to the backs of the brush sections, thereby holding the brush sections rigidly in alignment. The handle is disposed at an angle to the brush sections 'so that the operator may readily manipulate the brush over the surfaces to be washed.

Also carried by the backs of the brush sections between the central rows of bristles are perforated pipes 17 which are secured in any suitable manner to the backs of the brush sections. The perforations of these pipes are positioned so as to direct water therefrom divergently when the brush sections are moving over-the surface being scrubbed. These pipe sections are connected by a T-union 18 and due to the pipe sections being secured to nipple 19 to which a reducer 20 is connected.

A hose 21 connects ith the reducer and is provided with a suitable valve or cut-ofi' 22- for controllingthe supply of water to the brush during the operations of the xb'rushi, Thehose may be of the general construction and may connect with any suitable source of supply, such as is provided with a main control valve 23,'for turning off the supply of Water when finishing with the use of the brush.-' 7 t 1 In Figure 5, it will be noted that the T-' union 24' is slightly modified and connected to one legof the union is an elbow 25 to which a short pipe section 26 is connected. A second elbow 27 is connected to the-short pipe section 26 and carries a long tubular pipe section 28 which constitutes a handle and to which the hose may be connected for supplying water to the brush, which is identical inrconstruction with that shown in Figuresl to 4:. By this method of connecting the handle, 28: to the brush, it is possible to supply the water through thehandle and yet allow the handle" to move relative. to the brush as it. is moving over the surface being 7 soapto the bristles through the perforations, and means'for. supplying water to the bristles of the brushsectionsL 1 q 2.1m a scrub brush, the combination with a pair of aligned brush sections,"means connecting the backs of the brush sections, the

backs of the brush sections having depressed seats with perforations in their bottoms,
