BRUSH William D. Rose, Portland, Oreg.

Application February 15, 1938, Serial No. 199,641

1 Claim.

This invention is directed to an improvement in brushes and is designed particularly to provide a variety of brushes and attachments therefor to insure more eiective use and result from the brush employed.

The primary object of the present invention is to provide a series of brushes, one of which is designed more particularly for hand operation, and capable of use in connection with the brush fluid, such as water or air, for use on the surface to which the brush is being applied, the brush being particularly designed to permit its use in connection with acids, perfumes, or the like, whereby the brush may be better adapted for special uses.

A further object of the invention is the provision of a ferrule designed more particularly in connection with a fountain brush, which ferrule provides a means for gripping the brush for use in a convenient and secure manner, and further provides for the introduction of a cleansing fluid at will for distribution through the fountain brush.

A further object of the invention is the provision of means by which the ferrule of the fountain brush may be flexibly connected to a fixture to prevent the falling of the brush in its use in external cleansing.

A further object of the invention is the provision of a removable bumper designed to be slidably connected with the brush body and frictionally hel-d, without other fastening means, in position to safeguard any surface or article with which the brush may accidentally contact.

The invention is illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view of a fountain brush showing the means for supplying fluid thereto and the flexible means for connecting the brush against complete release.

Figure 2 is a section on line 2-2 of Figure l.

Figure 3 is a transverse sectional View through the brush and ferrule.

Figure 4 is a perspective view of one section of the flexible bumper for use in connection with the brush.

In the drawing, l have illustrated the improv-ement applied to a conventional iiat brush 4|. The improvement in this particular resides in the ferrule to be connected to the brush for use in handling the brush, connecting it against complete loss or separation, and distributing a cleansing fluid to the bristles 42 of the brush. The brush body is hollow, providing a chamber 43, through the bottom wall of which openings 44 lead to the bristles. The upper wall 45 of the chamber is preferably convex on its upper surface and centrally recessed throughout its full width to receive a flat plate 46 of the nipple 41.

This nipple 41 is provided with an outstanding extension 48 which is interiorly threaded at 49 and which communicates through an opening 50 in the upper wall 45 of the brush head with the chamber 43. The extension 48 is arranged at an inclination to the upper surface of the brush head and is positioned on one side edge of the brush, the inclination and vpositioning of the extension being such that when the brush head is grasped in the hand forA use, the nipple may be received between the thumb and first nger of the grasping hand to insure a more effective tension or grip of the brush head. y

The nipple 41 is secured in the recess in the upper wall 45 of the brush head through the medium of a bolt 5| which passes entirely through the brush head and is secured by a nut to facilitate -convenient removal. The nipple is further provided with a laterally projecting lip 52 formed with an opening 53 to provide for the removable connection of a strap, chain or the like 54 by which the brush, through the medium of the nipple, may be secured to any fixture, for exam-ple the safety belt of the user in the outside washing of the windows of buildings, in order to prevent falling of the brush an-d consequent danger to pedestrians on the pavement below.

The flat brush head is provided with end and side buffer means, shown more particularly in Figure 4, and including duplicate end elements comprising a flat plate-like section 66 and a marginal rim extending above and below the plate indicated at El. The buffer elements are of rubber or like material rand the brush head is slotted longitudinally of the upper wall 45. This slot 68 is arranged to receive the plate-like `sec-y tion 6B of the buffer element which is moved longitudinally of the slot, so that the rim Bl overlies vthe end wall of the brush head and a material portion of the side walls.

Of course, the buffer elements are arranged at both ends of the brush head and such elements are preferably secured by a screw pass-V of the brush. This constitutes a removable buierA which will prevent injurious effect through 'any 2 y 2,267,256 Contact of the brush body with an object during to receive a flexible connector, a nipple carried the use of the brush.
