Application filed December 31, 1914. Serial No. 879,888..

To all whom it may concern:

Be it known that I, FRANK TEMPLEMAN, a citizen of the United States of America, and a resident of Chicago, county of Cook, and State ot illinois, have invented certain new and useful Improvements in l `ountain Brushes, of which the following a specilieation.

The main objects of this invention are to provide an improved fountain brush; to pro- `vide a brush of this nature with means for directing iiuid streams from the sides of the brush toward its center, to there meet in the axial center line of the brush and produce a fountain causing the water to spread outwardly from the center' of the brush to the contact ends of the bristles; to provide a fountain brush with improved clamping means for securing the brush to the holder; and to provide a fountain brush with an iinproved arrangement of jet orifices whereby the brush is kept in thoroughly cleaned oondition while in operation.

An illustrative embodiment of this invenf tion is shown in the accompanying drawings,

in which- Figure l is a perspective View of a fountain brush constructed according to this inn vention.

Fig. 2 is a vertical longitudinal section of the brush.

Fig. 3 is a plan view of the brush stock and part of the brush holder,

Fig. 4 is a perspective view of a spo-nge and its support which may be secured in the brush holder as a substitute for the brush.

This invention provides a construction of fountain brush which is particularly suitable for cleaning automobile bodies. lt is usually necessary to employ a sponge for this work since brushes ordinarily constructed, cause the grit and dirt which is being removed to scratch the finish of the automobile. Fountain brushes have been constructed to direct a stream of water slightly in advance of the brush and some have been arranged to direct streams of water into the brush and also from the center out, but they have all been arranged in such manner that the ultimate result is impracticable for the class of work which is the aim of the present brush to accomplish. Prior devices frequently required a special construction of brush since the water was directed through its back, and others were not thoroughly self-cleaning since the jets of water were directed at the sides of a brush having the bristle tufts so arranged as to prevent the water from reaching the center of the brush and keeping it thoroughly saturated with a flow of liquid from the center outwardly.

In the present construction, the tufts of bristles are arrangedL in rows radiating from the centerI of the brush, thus providing a plurality of open spaces through which the streams of water may be directed so as to produce a fountain at the center of the brush. ln this manner, the water flows outwardly toward the operating or contact ends of the bristles, permitting the brush to be used with equal success when in inverted position. In the fountain brushes of this class which may now be obtained on the market, the water fails to thoroughly moisten the entire operating surface of the brush when used in inverted position, most of the water flowingover the outer edge of the brush stock, andbeing entirely useless, with the resultthat the grit, etc., scratches the surface being cleaned. For this reason no brushes have been provided which are suc cessful for cleaning automobile bodies, and this work is generally accomplished by means of a sponge. Y

The present invention provides a very substantial brush with a cast holder provided with a cored out water conduit surrounding its periphery, thus permitting the brush to withstand severe use without the water conduit becoming bent, and the present invention also provides a brush which, because of the peculiar manner of ow of water through the brush, may be successfully employed for extremely heavy work without injury to the surface operated upon.

Referring to the drawings, the brush support l consists of a casting forming a back 2 having a central opening or slot 3 for receiving a cam or clamping device l mounted on the stock 5 of the brush. The cam il is rotatably mounted and is adapted to readily slip through the slot 3 when turned longitudinally therewith. lt may then be turned transversely to the slot, the shoulders thereof riding upon and engaging the back 2, as shown in Fig. 2. The casting l at one end has extending from one end a threaded socket 6 for receiving a brush handle 7 comprising a plurality of pipe sections coupled together to form an extensible handle to which a hose coupling may be secured. The

. duit and is provided with a plurality of jet orifices 9, the orifices at opposite sides of the conduit being arranged to direct streams of water radially toward the center of theV brush and to meet iii-pairs along a line passing through the center of the brush transversely to the plane of the back thereof. A few of the jet orices are arranged to direct water against the tufts of bristles at the outer edge 10 of the body of bristles in order that the matter to be removed from the surface being cleaned is moistened in advance of the brush. orifices meeting on a center line passing through the brush, a fountain is rthere created which causes the water to flow outwardly to the operating ends of the bristles,

even when the brush is used in anv inverted position on the under side of a car body.

.F or the purpose of causing the operating surface of the brush to conform more closely to the form of the fountain produced in theL center/of the brush, the brush stock 5 is made of decidedly convex curvature. Also for the purpose of not obstructing the flow of water toward the center of the brush, the tufts of bristles 11 are arranged in rowsl between the jet orifices in the holder, which rows radiate from the center of the brush outwardly, as shown in Fig. 3.

A special cast back 12 is provided for supporting a. sponge 13 which may be stitched to the back with chamois 14, as shown in Fig. l, The sponge may therefore be readily substituted for the brush when it is desii-ed to use the device in light work where a sponge may bey preferred. Inmanufacturing thebrush holder, the core for the conduit is supported through the member 6 and apertures 15. These apertures are finally closed by screws, as shown'in Fig. 1, and provide means by which the conduit may be `ushed out if necessary.

A rubber buffer 16 is provided surrounding the rimrof holder l to prevent injury to surfaces losing'` cleaned by contact with said holder.

In the operation of the device, the water Copies of this patent may be obtained for B i the arrangement of `et Y :a .p Y the present invention provides a highly elnwhich enters `the brush holder from the handle 7 flows in two streams to the right .and left around the cored out conduit at the periphery of the holder. The jet orifices beingy suitably proportioned with this conduit cause the water to How in a plurality of streams of substantially equal strength between the rows of bristles and meet in pairs of streams in the axial line of the brush center, producing a fountain which causes the water to flow outwardly to the operating surface of thebrush, regardless of the position in which the brush is heldV during its motion over the surface being cleaned.

It may be seenfroni the foregoing that cient fountain brush particularly useful where the brush is employed in rather heavy work.

` 'Although but'one specific embodiment of this invention has been herein shown and described, itwill be understood that some of the details of the construction shown may be altered or omitted without departing from Y the spirit of this invention as defined by the .less removed from the brush holder.

2. A fountain brush comprising a brush and brush holder, said brush being provided Vwith radial rows of bristle tufts, and said holder being provided with a conduit encircling the brushV and having opposed jet orifices arranged to direct streams between the rows of tufts at different angles so as to meet at points indifferent planes more or less removed from the brush holder.

l Signed at Chicago this 26th day of Dec.,

FRANK TEMPLEMAN.
