' comme, (cils-13s) This invention relates to fountain brushes and more particularly to a. brush adapted 4for use in the cleaning of typewriters or the like.

An object of this invention is to provide an improved fountain brush -which is particularly adapted for use in the cleaning of typewriters so as to permit the use of a/cleaning uid when desired in the cleaning of the type or other parts of the machine.

Another object of this invention is to provide a fountain brush which is so consructed that it can be used with a detachable reservoir of 'a type such that the brush element can be transferred from one reservoir to another when the first reservoir becomes emptied.

A further object of this invention is to provide'in a brush of this kind, means whereby` the cleaning fluid is distributed over the entire bristle structure so that all o f the bristles will be moistened by the cleaning iiuid which is permitted by means of a spring pressed valve to flow into the brush.

A still further object of this invention is to provide in a brush of this kind means whereby the brush element can be removed from the head or handle so as to permit the ready replacement of the bristle structure when it has become unduly worn or unfit for use.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the following detailed description of the present preferred embodiment, the same-being illustrated in the accompanying drawing wherein:

Figure 3 is a fragmentary enlarged longitudinal sectional view of the brush element.

Figure 4 is a sectional view partly in detail taken on the line 4 4 of Figure 2.

Figure 5 is a top plan view of the removable brush element.

Figure 6 is a detail end elevation of the brush l element removed from the handle or the head.

Referring to the drawing wherein like numerals of reference designate. corresponding parts throughout the several views, the numeral 10 designates generally a reservoir or.receptacle provided with a threaded neck 11 on which a cap 12 having a knurled portion 13' is adapted to be mounted. A gasket 14 is adapted to be inter- Figure 2 is a detail side elevation partly brokenv posed between the cap 12 and the neck 11. A stem 15 is formed with the cap 12 and provided with a bore 16, and this stem 15 terminates in a head portion 17 also provided with a bore 18,` which is disposed on an angle to the bore 16 and 60 communicates at one end with this bore 16.

The head 17 is provided with depending flanges 19 within which the back 20 of a brush element 21 is removably mounted. 'I he marginal flange 19 at the rear of the head 17 is provided with a 05 slot 22 within which a tool or the like may be inserted to force the brush element 21 out of the head 17. The back of the brush element 21 is provided with a recess 23 providing a reservoir or liquid distributing means extending longitudinally of the back 20. The back 20 is provided with a pluralityv of discharge ports 24 which communicate at one end with'the reservoir 23 and open at the other end into the bristles 25 of the brush element 21. The passage 18 discharges into the reservoir 23 so that the liquid passing through the bore 16 will ow into the passage 18 and from there -into the reservoir 23, where the liquid is distributed to the various discharge ports 24, so that the entire bristle structure 25 will be satu- 's rated or moistened with the cleaning uid used in the reservoir 10.

In order` to provide means whereby the cleaning fluid dmay be discharged into the reservoir 23 as desired, I have provided a valve member 26 of tapering construction which engages a seat 27 provided in the head 17, and this valve 26 is'adapted to intersect the liquid passage 18 so as to close this passage when the valve is in closed position. A stem 28 is formed with the valve 26 and a but- 9 ton or valve operating member 29 is threadably mounted on the stem 2 8. The valve 26 is urged to closed position by means of a spring 30 which engages at one end against the bottom of a recess 31 provided in the head 17, and at the other end 95 engages against the cap or button 29.

The seat 27 for the valve 26 also communicates with the passage 18 and with the reservoir 23 so that there will be provided two discharge means 'or passages for the liquid iiowing downwardly 100 through the passage 18..

In the use and operation of this device, the reservoir lomay be of any desired configuration and construction such that this reservoir 10 may be sold separately from the brush element. .The cap 12 may be threaded onto the neck 11, and when, it is desired to use the cleaning iiuid for the cleaning of the various partsof a typewriter or the like', the button 29 may be depressed so as to move the valve 26 into open position and there- 11 by permit the cleaning fluid to pass downwardly through the passage 18 and pass the valve 26 and thence into the distributing reservoir 23. The fluid will also pass about the valve 26` and into the distributing Ireservoir 23 about the valve seat 27. When the brush element 21 becomes unduly worn, an instrument or tool may be inserted in the slot 22 and the brush element 21 removed therefrom, and a new element inserted in the head '17.

It will be apparent from thel foregoing that an exceedingly simple and practical fountain brush has been disclosed wherein the head may be removably engaged with the desired fluid reservoir which may be sold separately from the head, and. also wherein the brush element proper may be renewed or replaced when such is necessary. Y?

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
