JAMES F. DOWD, F NEWPORT, RHODE ISLAND, ASBIGNOR OF ONE-HALF TO FRANE` O. RICHARDS, OF NEWPORT, RHODE ISLAND.

BRUSH.

Application led March 14, 1928. Serial No. 261.586.

rlhis invention relates to brushes, and partirularly to brushes intended for use in association with a Water supply, capable of a great .number of uses.

The brush may be used in a dry state, or with Water, or it may even be employed in association with a vacuum producing means, in which event, a hollow handle may be connected to the suction creating means, although primarily, as stated, the brush is intended for use in scrubbing with Water or the like.

It has been found in` practice that the brush can be used for spraying vegetation in a garden or liothouse or the like, but its greatest utility, in far as has been determined, that as employed in cleaning or washing automobiles.

It is an object of this invention to provide a brush having a head With a cavity through which Water may circulate to a plurality of nipples or openings, from whence it is discharged between tufts of the bristles of the brush.

It lurtherinore an object of this invention to produce a brush having tufts of bristies, associated with means that are removably mounted in the head, and in which provision is made for the circulation of Water, as aforesaid.

lt is furthermore an object to produce a brush of this type Which Will be durable and eflicient.

lVith the foregoing and other objects in vien', the invention consists in the details of construction. and in the arrangement and ioinbination of parts to be hereinafter more fully set forth and claimed.

ln describing the invention indetail, reference Will be had to the accompanying drawings forming part of this application, wherein like characters denote corresponding parts in the several views, and in Which- Figure l illustrates a sectional view of a brush embodying the invention;

Figure 2 illustrates a plan View of one of the elements;

Figure 3 illustrates an enlarged sectional view of a fragment of said element; and

Figure l illustrates a sectional vieu7 of a modified construction.

In these drawings, 5 denotes a head having an opening 6 for the reception of a handle 7, which is in the nature of a pipe unit of the brush, to be presently described.'

In the present embodiment of the invention, a disk 12 of appropriate thickness has a peripheral threaded portion 13 which is threaded into the flange of the head, and the said disk is further provided Wit-h a peripheral flange 14: fitting against the lower edge of the lllange of the head. Recesses l5 are formed in the peripheral flange in order that a spanning Wrench. or other implement for imparting motion to the disk may be employed in installing or removing the disk from the head. rl`he disk is also 'provided with a plurality of apertures 1G Which taper from the inner to the outer surface of the disk and these apertures aline or register With apertures 17 formed in a brush plate 18 which assembled With the disk as a brush. unit. The plate 18 may carry a. plurality of brush tufts 19 which as to number is immaterial.

Nipples or tubes 20 are arranged in the apertures of the disk and plate and preferably they project at the outer surface of the plate, and the ends preferably are shaped or upset to forni flanges 2l which serve to hold the disk and plate assembled. Owing to the tapered contour of the apertures of the disk and the fact that the nipples are shaped to those contours, a Wedging action` results between the nipples and the disk, which serves, in association with the flanges, to retain the parts assembled.

Since the brush unit may be removably applied to the head, brush units of different qualities or characteristics may be employed in association` with one head. For rough Work, a brush unit With relatively heavy bristles may be employed, Whereas Where polishing or other delicate operation." are to be performed, bristles of different texture and quality may be used.

Inl that form of the invention illustrated in Fi ure 4, the head 22 has a connection 23 for a olloW handle and it also has an apertured bottom Wall 24 with depending hollow nipples 25. The brush element 26 has apertures 27 to receive the nipples and the said brush element is secured to the head by fastenings 28, such as screws, and there is an interposed packing 29 to efect a tight joint between the brush element and the head.

I claim:

In a fountain brush, a hea-d having a cavity, a hollow handle attached to the head and communicating with the cavity, the said head having a threaded inner wall below the cavity, a brush unit comprising a disk having tapered apertures, said brush element having a threaded peripheral portion engaging the threads of the brush unit and a flange extending under the brush unit at its periphery, a plate coextensive with the under surfa ce of the brush unit having brush elements attached thereto associated with the said disk and having apertures alining with the apertures of the disk, tubular members fitting the apertures of the disk and projecting through the apertures of the plate the ends of said tubes being flanged to engage the outer surface of the plate for holding the plate and disk assembled, and a gasket interposed between said brush uut and the head.
