PAlRlUK F. BARRETT, OF SAN FRANCISCO, (YALIFORNIA SCRUBBlNG-BRUSH.

SPECIFICATION formingpart of Letters Patent No. 595,012, dated December 7, 1897.

Application filed November 23,1896. Serial No. 613,213. (No model.)

To all whom it may concern:

Be it known that I, PATRICK F. BARRETT, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Scrubbing- Brushes; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

My invention relates to an improvement in that class of window andscrubbing brushes wherein the water isconducted from a source I 5 of pressure through a flexible hose to a hollow handle and thence through the hollow handle and brush to the place where the water is required.

My improvement provides a soap-chamber to be used in connection with the scrubbingbrush and a means for enabling the operator to divert the course of the water from the brush and cause it to pass through the soapchamber to soften the soap at the time it is being applied to the surface to be cleaned. This soap-chamber is so disposed with refer ence to the brush that the soap can be applied by simply turning the brush without requiring the operator or user to change his position materially, all as hereinafter more fully described. I attain this object by the mechanism illustrated in the drawings, in which- Figure 1 is a side elevation of the brush,\vith the tubular handle attached to the hydrant by a flexible hose. Fig. 2 is a cross-section through the center of the brush. Fig. 3 is a plan view of the brush. Fig. 4 is a cross-section of the locking device.

The scrubbing-brush A is connected with the hollow handle K by a socket B, set in the back of the brush and having screw-threads cut on its inner surface to receive the screwthreaded handle. Openings 0 D are made in the sides of the socket B, and a hole E is 5 drilled in the socket end of the handle which screws into the s0cket,'so that by turning the handle K the hole E may be brought in line with either of the openings 0 D, as desired, while the other is closed. Leading directly from the hole or port C is a passage P, which connects with the SO11)'-Cllll)1b"lG, and from this chamber other smaller openings CLCL admit water directly into and over the bristles of the brush, so as to introduce the soapy water to the brush and surface to be cleansed.

Another passage H leads from the opening or port D in the socket B through the back of the brush into and over the bristles, and through which clean fresh water is conducted to thebristles of the brush when the handle, is turned so-as to bring the openings opposite each other. When a supply of water is turned on and the hole 0 in the socket brought in line with the opening E in the handle, the stream of water is directed through the ob annel F and soap-chamber G, thereby supplying a mixture of soap and water to the brush and the surface to be cleansed. When a sufficient quantity of soapy water. has been conducted to the surface to be cleansed, the water is turned 0E by means of a cock N in the usual way. The operator then presses down on the spring-actuated lever T, releasing the end 01 the same from the slot U in the locking device and giving the brush a half-turn, bringing the openings E of the handle and D of the socket in line and looking it in that position,

so that when the water is again turned on it is led through channel H into and over the brush, thereby supplying clear water to the brush. A locking device, is attached to the pipe-handle K and is fixed directly above the upper surface of the flange-socket B, and consists of a collar R,having an arm S. At the outer end of said arm a spring-operated latch T is hinged. 'lhislatch is adapted to engage in the notches U U, cut in opposite sides of the flange V of socket B. The notches in said flange are so located as to lock the brush firmly in place whenever the openings or ports in the handle and socket come opposite each other.

Having thus described'my invention, what I desire to secure by Letters Patent is-- In a scrubbing-brush a soap-chamber connected by passages with the brush portion, a hollow handle connected with the soap-chamber by a hollow swivel-joint, and adapted to be reversed so as to connect it with or disconnect it from the soap-chamber, and a lock- 10o ing mechanism adapted to lock it in either position, substantially as described.

In testimony whereof I have hereunto set my hand this 13th day of November, 1896.

PATRICK F. BARRETT.
