JOHN AULD, OF CHICAGO, ILLINOIS.

FOUNTAIN IBRUSH.

Specification of Letters Patent.

Patented May i5, 191?.

Application filed July 17, 1916. Serial No. 109,763.

To all whom it may concern:

Be it known that I, JoI-iN AULD, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain-Brushes, of which the following is a specification.

My invention relates to improved fountain brushes whichare particularly adapted for use by stenographers in cleaning ink and dirt from the type of typewriting machines.

The object of the invention is to produce a simple device of this kind which can be sold for a reasonable sum and which can be efficiently operated to control the supply of cleaning fluid to the brush bristles.

On the accompanying drawing structures are shown which embody the features of my invention, and in these drawings- Figure 1 is a side elevational view partly in vertical diametral section of a fountain brush,

Fig. 2 is an enlarged sectional view on plane 22, Fig. 1,

Fig. 3 is a view similar to Fig. 1, showing a modified construction, and

Fig. 4 is an enlarged sectional view on plane 4-4, Fig. 3.

In the construction of Figs. 1 and 2 a squirt can 5 for containing cleaning fluid has the threaded neck 6. In this neck the cup-shaped plug 7 has detachable screwthreaded engagement, a discharge spout 8 bein secured at its lower end in the bottom of the plug and being open there to the can contents. A tube or cap 9 closed at its upper end is adapted at its lower end 10 for threaded engagement in the plug 7. At its upper end the tube has the valve 11 preferably in the form of a rubber or leather block which is held firmly against. the end of the spout 8 when the cap is en tirely screwed into the plug, thereby closing the spout. The construction thus far described is that found in well-known cans now on the market and widely used by stenographers for containing lubricating oil. a

In accordance with my invention I attach a continuation to the cap in the form of a tubular holder 12 for brush bristles 13, the lower end 14 of this holder being slipped over. the end of the cap and against the knurled beading 15 usually provided on the cap. The holder 12 is off-set at 16 so that the section above the end 14 is of larger diameter and spaced away from the cap end just below the valve. 11, the cap end being provided with outlet openings 17 leading into the holder tube above the oil'- set. W'ith this arrangement, when the cap is unscrewed a distance in the plug 7, the valve will be raised and the spout opened, and then when the can is inverted and the sides pressed the cleaning fluid will be ejected into the cap end and will flow through openings 17 into the brush holder and to the bristles 13 to be received by the type or surface over which the bristles are rubbed to effect cleaning. When the cap is again screwed down tight the valve closes the spout.

In Figs. 3 and 4 I have shown a modified arrangement. Instead of having the bristle holding tube a separate member applied to the can cap, the holder and cap are an integral tubular structure 18 having the flared upper end 19 for receiving the bristles 20 and having its lower end 21 threaded to engage in the plug 7 of the can. Below the bristle seat 19 the tubular structure is of reduced diameter to provide an internal seating shoulder 22 for a supporting disk 23 for the valve or stopper 24 which stopper engages with and closes the spout when the tube 18 is screwed fully into the cap. Through the disk 23 are a number of outlet passageways 25 through which cleaning fluid can flow when the tube 18 is unscrewed a distance and the spout opened,

the fluid then flowing from the spout into the tube and through the passageways 25 to the bristles 20.

The devices shown comprise few and simple parts and can therefore be very cheaply manufactured and sold. Normally the fluid container can is sealed, and can be put into operative position for cleaning purposes by merely giving the brush holding tube structure a sufficient turn to withdraw the valve or stopper from the spout end. If it is desired to apply the fluid directly to parts or surfaces t6 be cleaned the brush holding tube can be entirely removed from the can and the can then used in the ordinary manner to squirt fluid through the spout.

I do not, of course, desire to be limited to the exact construction and operation shown and described as changes may be possible which would still come within the scope of the invention. I claim as follows:

1. The combination with a fluid container spout and to be secured at its inner end to the container, bristles at the outer end of said tube, a stopper within the tube engaging against the spout outlet, and a by-pass around said stopper for the flow of fluid to the bristles.

2. In a device of the class described, the combination of a fluid container having a neck, a spout extending at its lower end through said neck and open thereat to the container, a tubular holder adapted at its lower end for insertion in said neck, bristles at the upper end of said holder, and a stopper within the holder held against the spout outlet when the holder is fully inserted in said neck and released from the spout outlet when the holder is partially withdrawn from the neck, there being passageway around the stopper whereby the container contents will flow through the spout and through the holder to the bristles when the stopper is withdrawn from the spout.

3. In a device of the class described, the combination of a fluid container having a threaded neck, a cup-shaped plug having screw-threaded engagement in said neck, a spout secured to the bottom of said plug and Xtending outwardly therefrom, a tubular brush holder having threaded engagement at its inner end in said plug and hav ing bristles at its outer end, and a stopper secured in said holder and normally engaging with the spout end, partial unscrewing of said holder causing the stopper to be withdrawn from the spout whereby the container contents may flow to the brush holder, there being by-passageway around said stopper whereby fluid may flow to the outer end of the brush holder and to the bristles.

In witness whereof I hereunto subscribe my name this 13th day of July, A. D. 1916.

JOHN AULD.
