To all whom t may concern:
Be it known that I, MARTIN W. NELSON, a citizen of the United States, residing at Harlem, inthe-county of Blaine and S't-ate ofv Montana, have invented new and use-- ful Improvements in Fountain Blacking- Brushes, of which the following is a specification.
This invention relates to a fountain blacking brush and particularly directed to a simple means for controlling the flow of the fluid from the reservoir to the brush'bristles.
The main object of the invention is the provision of a fluid-receiving chamber located immediately adjacent the bristles for the reception of the blacking and the control of the flow of such fluid blacking from the chamber to the bristles.
The invention in its preferred form of details will `be described in the following specification, reference being had to the accompanying drawings, in which- Figure 1 is a longitudinal sectional view of the improved fountain blacking brush. Fig. 2 is a longitudinal sectional view of the control plug. Fig. 3 is a view in elevation of the brush head.
Referring particularly to the accompanying drawings, the improved fountain blackingbrush includes a reservoir 1 which may bel of any desired sectional area or length, being preferably, however, of elongated cylindrical form having a -illing opening-2 at one end designed to be closed byV a remov- .Projecting from the end` of the reservoir opposite the filling opening is a-cylindrical extension 4 ,longitudinally formed with a channel 5 in communication with the interior of the reservoir, said` channel 5 at a point opposite the delivery end being enlarged to form a `chamber 6. Atthe juncture of the respective portions of the channel 5 the projection, or neck 4 is formed with a transverse: opening 7 intersecting thechannel 5 and designed 'toreeeive theplug 8. The plug 8 which is preferably threaded in the neck,"is formed with an opening 9 to register with the channel. 5 when the plug is in one posit1on,.and wlth an air chamber 10 extending longitudinally through the plug opening at one end through the head thereof and at the opposite endthrough the wall of the plug inV transverse alinement with the openingy 9 but at right angles thereto, that is, spaced a distance therefrom equal to one-fourth the circumference of the plug surface.
The brush proper includes a head 11 corresponding in diameter to the similar dimension ofthe free end of the neck 4 and bristles 12 secured to the head in any appropriate way, the head being formed with an opening 13 to register with the chamber 6. The side edges of the head are provided with clips 14 which extend beyond the free surface of the head and are designed to engage suitably formed projections 15 carried by the neck adjacent the free end thereof, whereby the head may be locked to the neck or removed therefrom, as may be desired.
In use,with the plug turned to cause the opening 9 to register with the channel 5 and chamber 6 the liquid blacking from the reservoir is forced into the chamber 6 by ashaking operation. When any sufficient quantity of the liquid blacking is in the chamber the plug 8 is turned so as to cut off communication Abetween the'channel 5 and chamber 6 andv to establish communication between the chamber and atmosphere through the duct 10. The contents of' the chamber will then flow readily through the head 11 and onto the bristles` to be applied to the shoe in the usual manner.
I contemplate the formation of the blacking brush of any desired size or shape and to adapt such brush without regard to its size for connection with the reservoir. substantially in the manner described.
I lprefer to completely inclose the operative end of the brush by a thimble casing 16 which frictionally engages the. end of the reservoir 1. By this arrangement the improved fountain brush may be handled or carried when not in use without liability of the brush end soiling other'articles.
