Specification of Letters Patent.

FOUNTAIN-BRUSH.

Patented June 25, 1912.

To all whom it may concern:

Be it known that I, EDWARD BUSCHMAN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Fountain- Brushes, of which the following is a specification.

My invention relates to improvements in fountain or self moistening brushes and has for its general object to provide a simple, cheap, and eflicient reservoir brush constructed to permit a dust allaying fluid constantly to be fed to the bristles from the reservoir when the brush is in use.

One of the more particular objects of my invention is to provide a brush with a detachable reservoir; and other objects. are to provide animproved metal reservoir construction; to provide improved fluid-delivery means in association with the bristles;

and generally to improve the construction of brushes of the character described.

In the drawings, Figure 1 is a perspective view of the brush embodying my invention; Fig. 2 is a transverse vertical section therethrough; Fig. 3- is assimilar section through a portion of the brush showing one of the feeding nipples; Fig; 4 is a longitudinal vertical section through a portion of the brush; Fig. 5 is a plan view of a fragment of the brush with the reservoir removed; Fig. 6 is a view similar to Fig. 4 showing a modified construction embodying my invention; and

-Figs. 7 and 8 are a transverse sectional and an inverted plan view of the reservoir structure shown in Fig. 6.

In the embodiment of my invention I provide a suitable brush 10, of size and contour appropriate to the character of the work to ,be done, said brush comprising generally a in the base extending only part way through the apertures 13.

In practice, only a relatively small number of bristle bunches need be directly supplied with dust allaying fluid in order that the entire brush may quickly have its its entire sweeping surface affected, and such of the bunches as are to receive the fluid are preferably mounted in specially constructed sockets. Thus, as shown in Figs. 4 and 5, only a limited number of the bristle bunches or tufts constituting the central row of the brush are arranged directly to receive liquid and each of the apertures 13, in which such selected bunches are secured, is provided with a metallic bushing or thimble 15 extending through the body 11 and flanged at its upper and lower ends to overlie the horizontal surfaces of the body 11 in a border about the aperture. By this arrangement the bristle body connected to receive fluid from the reservoir to be described is retained out of contact with the base 11, which may be made of wood and which would otherwise tend to absorb liquid from the bristle bunches.

The reservoir structure, generally indicated at 16, is a liquid tight tank, preferably segmental in cross section, and formed of sheet metal, mounted upon the top of the brush body 11 and having protruding from its flat lower side nipples extending into the thimbles 15 to supply oil to the selected bunches of bristles 12. c

In the construction shown in Figs. 1 to 4, the metal reservoir or tank 16 is formed from a tubular blank, flattened along one side, and having the extremities of its aI'cuate portion formed as at 16 into downwardly trending end walls meeting and secured, as by soldering or other means, to the flat bottom wall 16". The flange 17, formed by the juncture of these walls is secured as by screws 18 to the body 11 of the brush. If preferred, however, the ends of 'the tank may be formed of separate sec one of such apertured nipples, when the reservoir is in place, extending into each of the thimbles 15. As illustrated in Figs. 3 and 4, the .nipples may be formed directly in the base of the tank or, as indicated at 19 in Fig. 6, they may be separate, apertured l studs suitably secured in the bottom of the tank.

As a means for restricting the flow of liquid from the tank to the bristles I preferably provide between each nipple 19 and the associated bunch offbristle an absorbent pad or body 21, preferably a piece of felt or like material completely fillin an area 5 of the thimble 15 between the bristles and Within the bow 26'is placed acylindrical nut 28 having itsbore extending therein from it's cylindrical surface to receive a machine screw' 29, the opposite extremity of which is firmly secured inthe handle proper 30. The screw 29 passes through the slot 27 and exteriorly through the bow 26 and carries a washer 31 loose upon the screw and preferably having its under side cylindrically dished or curved corresponding to the outer surface of the arcuate bow 26. A jam nut is provided, as at 32, upon the screw 29 betweenthe washer 31 and handle 30.

In, the operation of the device it will be obvious that the handle may be set at any angle at either side of the brush, it being necessary, to this end, only to turn the ban dle 39, and'with it the screw 29, in such direction that the screw retreats from the cylindrical nut 28, thereby 'to loosen the handle with respect to the bridge 25, and after adjusting the handle at the desired angle, to

' turn. it in the direction which will cause the screw 29 ,to penetrate the nut 28, thereby forcing the dished washer 27 down upon the bow 26 and in conjunction with the nut 28 to clamp the handle tightly in place upon the bridge.

The reservoir is filled with the liquid for allaying the dust, such for instance as a kerosene mixture, or water, or any desired liquid, through the mouth 23, and the liquid feeds down through the nipples 19 upon the retarding pad 21 of felt, gradually to seep through the felt by capillary action to moisten the subjacent bristles. The arrangement of the nipples l9 and the bristles to be supplied with liquid, within the thimbles 15, protects the body llof the brush against absorption of the moisture to a material extent; and the penetration of the nipples into the thimbles brings them into contact with the felt pads 21 to prevent possible flooding of the thimbles.

While I have herein described in some detail specific constructions embodying my invention and for purposes of full disclosure, it will be obvious to those skilled in the art, that many changes in the details .of construction might be made without departure from the spirit of my invention and Within the scope of the appended claims.

' What Iclaim is:

1. A reservoir brush construction providing a plurality of tufts and a separable detachable reservoir provided with independently restricting means for separately supplying variable quantities of fluid to each of a selected number of tufts.

2. In a reservoir brush, a base having bristle-receiving apertures therethrough, bristles secured in said apertures and extending onlypartially through the base, a reservoir mounted upon the said base having nipples provided with an opening extending into said apertures, and an independent absorbent bod interposed between the bristles and the nipples, in each aperture. V

In testimony whereof I hereunto set my hand'in the presence of two witnesses.

EDWARD BUSCHMAN.
