matter of a copending application and has for the primary object, the provision of an improved head having the bristles removably secured thereto and provided with a fluid conducting passage to direct fluid to the bristles and is so lo shaped that the fluid supply means may deliver fluid thereto regardless of the positions occupied by the head with respect to said uid supply means.
With these and other objects in view this instruction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation partly in section illustrating a brush constructed in accordance with my invention. 4
Figure 2 is a vertical sectional view illustrating the same.
Figure 3 is a plan View illustrating the device. Figure 4 is a sectional view illustrating the rotatable means for connecting the fluid supply 39 means to the brush head.
Figure 5 is a plan view illustrating the head.
Figure 6 is a sectional view taken on the line V6--6 of Figure 5.
Referring in detail to the drawing, the numeral 1 indicates a brush head of substantially rectangular shape and has formed therein a iiuid passage 2 opening outwardly through one face of the head and sockets 3 are formed in the head 1 at opposite sides of the passage and at the discharge end of the latter and in which tufts of bristles 4 are mounted so that fluid discharged from the passage will engage the bristles moistening the latter as well as the surface being cleaned by the device. The fluid discharging through the bristles keeps the latter free of for eign matter. Each tuft of bristles consists of a series of strands folded upon themselves within the sockets 3 and about fasteners 5. The fasteners 5 are in the form of split rivets which are carried by the head and extend through the passage. The head is provided with openings to receive the fasteners and after passing said fasteners through the openings the bifurcated ends i thereof are spread or offset.
The passage 2 is offset to form la chamber 6 arranged laterally of the discharge end of the passage. A plug '7 is journaled in the head and has a port 8 in communication with the chamber and receives the tapered end of a connecting nozzle or element 9, the latter being tapered so as to wedge in the port 8. The nozzle 9 is adapted for connection witha fluid supplymedium l0. The head is provided with a cut-out portion dening spaced walls l1 between which extends the nozzle. Gne end of the plug 7 is offset to 65 form a stop 12 engaging one of the side faces of the head while the opposite end of the plug is provided with a screw threaded extension 13 to receive a nut 14. The tightening of the nut 14 on the extension 13 will cause a binding of the 79. plug in the head and thereby hold the head against movement with respect to the nozzle 9 and also draws the nozzle against one of the walls 11 with considerable force, aiding in retaining the nozzle in the port 8. The slackening of the nut 14 on the extension 13 will permit the head to be adjusted with respect to the nozzle to assume positions aslshown'in Figure 1 still maintaining the discharge end of the nozzle in co munication with the chamber 6 of the passage 2. .89
From the foregoing description taken in connection with the accompanying drawing it will be noted that the bristles may be easily removed and replaced by-others when necessary by simply removing the fasteners 5 and also it is to be .8.5 noted that the head may be easily adjusted into several positions with respect to the nozzle without interrupting communication of the nozzle with the chamber 6 of the passage 2, and the consequent flow of fluid through the head to the 99 bristles will not be disturbed in any of the positions occupied by the head. The adjustment of the head with respect tothe nozzle 9 also permits the use of the .brush at different angles with respect to a surface' or object to be cleaned. 95
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and. arrangement of parts may be made without departing from the spirit and 1.00 scope of my invention, as claimed.
Having described the invention, I claim:
l. A brush comprising a head having a fluid passage opening outwardly through Vone wall tnereoabrisnes Carried by said head about the .105 discharge end of the passage, said head having a chamber in communication with the passage and offset laterally therefrom, a member rotatably secured to the head and having a port to receive a nozzle and communicate the latter with the no chamber, said head having a cutaway portion iforming spaced Walls between which extends said nozzle.
2. A brush comprising a head having a fluid passage opening outwardly through one wall thereof, bristles carried by said head about the discharge end of the passage, said head having a chamber in communication with the passage and offset laterally therefrom, a member rotatably secured to the head and having a port to receive a nozzle and communicate the latter with the chamber, said head having a cutaway portion forming spaced walls between which lextends said nozzle, and means on said rotatable member for securing the latter to the head against rotation and for binding the member against one of the walls of the head.
3. A brush comprising a head having a fluid chamber opening outwardly through one "face thereof, bristles carried by the head, spaced walls formed on said head, a plug member having a port journaled to the head with the port in communication with the chamber, said port adapted to receive a fluid supply nozzle with a portion thereof operating between said walls, means on said plug to releasably secure the plug to the head and adapted to permit movement of the nozzle between the walls for adjusting the head relative thereto and to draw the nozzle against one of `said Walls for holding the latter in the port when the plug is secured against rotation with respect to the head.
