a corporation of Louisiana Application February 19, 1938, Serial No. 191,520

Renewed June 20, 1940 2 Claims.

' This-invention relates to a brush, the general object of the invention being to provide means whereby 'thepaint or other material is supplied to the bristles of the brush under pressure, with a valve in the handle of the brush for controlling the flow of material to the bristles and with means whereby the parts of the brush can be easily disassembled forrenewal and cleaning and other purposes.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which- Figure 1* is an elevation of the improved brush with the parts in section.

Figure 2 is a section on the'line 2-2 of Fig- 'ure 1.

Figure 3 is a view showing how the distributor member for distributing the material to the bristles of the brush is detachably connected with the headed tube which is threaded into the supply conduit in the brush handle.

Figure 4 is a view of this headed tube.

In this drawing the numeral I indicates the handle of the brush which is provided with the 'head part" 2 which is formed with the rim 3 having an internal groove 4 therein. The handle is of hollow construction to provide the conduit 5, the outer end of which is threaded as shown at 6 to receive the end of a supply conduit through which the paint or other material passes under pressure. The head 2 is formed with a passage 1 which forms a continuation of the conduit 5 and this passage has a threaded end 8 which opens out into 'the central portion of the space formed by the rim 3. A. tapered valve 9 intersects the passage .1 and has a handle III at its large end which bears against a stop II on the base 2 when the valve is in open position. The base of the bristle par't i2 is located in a metal member 14, slotted as shown at 15 and provided with the external rib I6, the slots making the member 14 sufiiciently resilient to permit it to be pressed into the rim 3 so that the rib IE will engage the groove 4 to detachably hold the bristle part to the handle part.

A tube 11 has a threaded end 18 for engaging the threaded end 8 of the passage 1 and the other end of the tube is formed with a head 19 .a-tions 20 of the tube having perforations 20 therein, said head being located within the bristle part 12 when the end I8 is threaded in the part 8. A member 2| formed of rubber or the like is composed of a hollow head 22 for removably fitting over the 5 head 19 of the tube 11 and the tubes 23 whioli are in communication with the 'head'22 so as to receivethe material passing through the perfor- 11. These tubes 23 distribute the material through their open outer ends in into the bristle part I2. The drawing shows this member 2| as provided with a straight central tube 'and diverging side tubes audit is to be understood that these tubes can be arranged as. desired to evenly distribute the material to the 15 bristles.

In assembling the parts the head portion of the bristle part is pressed'into the space formed by the rim 3 so that the rib IE will engage the groove 4. Then the tube I1 is passed through the 20 bristles and through a 'hole formed in the head part thereof and its end i8 threaded in the part 8 of .the passage 1. Then the rubber member 21 has its head 22 pressed over the head-l9 of the, tube 11. Then the brush is ready for use. The 25 part 6 is suitably connected with a hose or other conduit leading from a supply of paint or other materials to be applied by the :brush and then the brush is used in the usual manner, the supply of material to the bristles being controlled by 3 manipulating the valve 9 by means of the handle l0.

As before stated the parts of this brush can be readily disassem-bled'for cleaning, repair or renewal purposes and readily reassembled and in 35 disassembling the parts it is simply necessary to remove the member 21 from the tube 11 then unscrew the tube l1 from the base or head part 2- and then the bristle carrying part can be pulled from the handle part. l

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combina- 4 tion and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. In a fluid distributing attachment for fountain brushes, am'gid tube secured at one end to a hollow brush handle, a rounded head on the other. end of the tube and positioned in the bristles of the brush, said head having openings therein, 55

certain of said openings being ofi-set from the longitudinal axis of the tube and a. flexible dis- 'charge member embodying a head conformably fitted over the head of the tube and a plurality of flexible tubes positioned in the bristles and extending from the last named head and said flexi-ble tubes being adapted to register with the respective openings of the first named head.

2. A brush comprising a handle part having a passage therethrough, a valve for controlling the flow of material through said passage, means for connecting the outer end of the passage to 2.

ment with the walls of the rim of said handle 10 part.
