1 Claim.

This invention relates to a paint brush, and has for the primary object the provision of a device of this character which will greatly facilitate painting by eliminating the necessity of dipping the bristles of the brush into paint of a container each time paint is needed on the bristles and eliminates the loss of time incident to such practice, consequently permitting the painting operation to be more rapidly carried out and with less effort on the part of the painter.

Another object of this invention is the provision of means under convenient control of the painter for distributing paint into the bristles of the brush from a source as the need for paint occurs during a painting operation, which obviates the necessity of the painter having to reach distances from the surface being painted in order to replenish the brush with paint.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination andarrangement of parts as will 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 drawings, in which Figure 1 is a front elevation illustrating a paint brush constructed in accordance with my invention.

Figure 2 is an edge elevation illustrating the brush and the means of controlling paint from a source to the bristles of the brush and acting as a handle for the latter.

Figure 3 is a fragmentary vertical sectional view illustrating the means of distributing the paint to the bristles of the brush. I

Figure 4 is a vertical sectional view illustrating a control valve for controlling the paint to the brush.

Figure 5 is a detail sectional View illustrating a coupling for detachably connecting the handle portion to the brush head.

Referring in detail to the drawings, the numeral 5 indicates a brush head of any suitable shape and size in which are embedded bristles 6. Mounted in the head 5 are rigid tubes or pipes I each having an end thereof terminating where the bristles leave the head 5 while the opposite end projects beyond the head and is equipped with a coupling 8.

The couplings 8 are employed for detachably connecting the pipes 'l and also to the head 5 a handle 9 including a pair of rigid pipes l0 connecting to an outlet of a valve II. The pipes H) and valve H go to make up the handle 9 and the pipes Ill are detachably connected to the pipes I by the coupling 8 so that Whenever the bristles of the brush become worn a new brush head may be adapted to the pipes i0. Also this construction will permit brushes of different sizes to be adapted to the handle 9.

Further, it is to be understood that the number of pipes l in the brush 5 may be varied in accordance with the size of the brush head and the amount of bristles carried thereby.

The inlet of the valve, designated by the character l2, has a fitting l3 connected thereto to which is connected a paint supply hose l4 leading to a suitable paint source (not shown). It is preferable that the paint source be of the pressure type so that the paint will be fed to the valve under pressure. Furthermore, the hose I4 is flexible so that the brush in entirety may be moved freely into various position-s for carrying out a painting operation.

The valve H includes a spring seated valve element l5 engaged by a slidable plunger i6 provided with a finger piece IT. The plunger l6 operates within a suitable packing gland l8 removably secured in the body of the valve II, as shown at I 9. The painter by placing pressure on the finger piece Il, may unseat the valve l5 to permit a desired amount of paint to flow through the valve into the pipes 7 for distribution to the bristles 6.

Soft flexible tubes 20 are connected to the pipes and extend into the bristles 6 terminating short of the free ends of the bristles, as clearly shown in Figure 3. The purpose of the soft flexible tubes 20 is to distribute evenly the flow of paint from the pipes I to the bristles. The flexible tubes 2|) the bristles of the brush and also to assist in preventing the tubes 20 from moving out of the during the painting operaand the tubes 20 for dithe pipes 7 into the bristles 2| From the foregoing description taken in connection with the accompanying drawings it will be seen that a painter can conveniently grasp the handle 9 and move the brush freely relative to a surface to be painted and by placing pressure on the finger piece I! with the finger of the hand gripping the handle may admit paint to the bristles of the brush as need for paint occurs during the painting of the surface. It will therefore be seen that through the use of this invention painting operations may be easier to carry out and larger areas successfully covered with paint with less efiort on the part of the operator or painter.

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 scope of the invention as claimed.

Having thus described the invention, what'I claim is:

In a paint brush, a head, bristles secured to the head, tubes mounted in the head and extending into the bristles and including couplings arranged exteriorly of and close to one end of the head, rigid pipes detachably connected to said tubes by said couplings and including oppositely curved portions merging into each other to form a valve housing cooperating with the pipes in providing a handle for the head, said housing having a pas- 10 sage connected to both pipes at one end and havingthe otherv end thereof screw threaded, a fitting of a supply means threaded into the lastnamed end of the passage, and a compressible valve mechanism carried by the housing for con- '15 trolling fluid through the passage from the supply means to the bristles.
