Application filed' February To @Zlio/0m t may concern.' y

lie it known that L Amro RAr'isannr. a citizen or'A the United' in'eates.v residing at loston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Brushes. oit whichthe following' is specification.

This invention relates to brushes. and is especially concerned with fountain brushes ol' the type'used in painting'. y

lt is the chief object oit the invention to devisea brush ol this tv'oe which can be cleaned more thorounhlyrand conveniently than brushes oi" this character as heretofore constructed, which can be mamitactured economically, and which can be conveniently .repaired rlhe nature of the .invention will be readily understood from the following description when read in Connection with the accompanying` drawing, and the novel features will be particularly pointed out in the appended claims.

The 'single ligure ot the accompanying" drawing a vertical. cross-sectional view ol" a, brush embodying' the invention in the torni at present preferred, some parts et the brush being shown in elevation.

The construction shown comprises a hollow head 2 lniving` a handle 3 extending' from one end thereof, the handle also beine' hollow and grooved at its upper end to receive the hose or tube which supplies paint.. varnish, or other liquid to the brush. Assuming that this brush is of the round type, the lower end of the head will be tubular in fo an. Fitting" within this head is a valve block lhaving,` a peripheral flange 5 projecting from its lower end and overlying the end ol the. head 2. The brush body is separate troni, and independent of, this block, and includes a body of bristles 6 conned between an inner metal tube Z and an outer metal sleeve 8. In the process of assembling these parts, the portions of the bristles between the tube and the sleeve are embedded in glue, or some suitable adhesive. and a tube or sleeve 9 of wood, libre, or metal is driven into the position shown in the drawings to wedge the bristles firmly against the sleeve S. l/hen the adhesive has hardened or set. the bristles will be secured lirrnlv in place. Projecting from the upper end of the sleeve 8 is a flange 10 which abuts against the flange 5 of the valve block, as clearly shown in the drawing. Both the valve block and 6, Serial No. 690,978.V

the brush body are removably secured to the head by collar 12 which is threaded on .2 the head and is constructed to clamp the flanges 5 and 10 firmly against the lower end of the head.

For the purpose `of conducting' the paint, or other liquid being' used, from the hollow head into the body ot' the bristles. the valve c block t has anipple 14 extendingN from the lower end thereof to which a flexible rubber tube is connected, both the nipple and the part l having a passage therethrough for thellow of 4paint into the tube. The ilow of paint regulated by a valve 16 arrangred to tit in a seat formed in theupper end et a block Il and guided partly by a stein 17 that projects into the paint passage and partly by an extension 18 which projects through a hole formed in a brace 19. This brace eX` tends entirely across the space in the head 2 and is either soldered or riveted to the head` in adjusting` screw 2O is threaded through the wall of the head 2 and bears on the upper end of the part 1S of the valve, while a springl 21 located below the valve serves to litt it oiTits seat and to hold it normally in Contact with the inner end of the ad'usting; screw. Consequently, by turning the screw 2O the low ot' paint to the brush may beadjusted very accurately.

It will now be evident that in order to clean the brush it is merely necessary to un screw the collar l2, then remove the brush body and the valve block and wash all these parts in turpentine or any suitable cleaning ,liquid` Since all the parts are exposed and readily accessible, it is an easy matter' to clean them veryuthoroughly. The parts of the brush may then be reassembled, this operation requiring but an instant, and the device is then ready for use again. It desired, the brush body may be replaced by another of the same construction. The fact that the brush body and the. valve block are independent of each other, is of advantage not only in cleaning;v the brush, but also in renewing` the bristle body or brush body when it becomes worn. The otherV parts of the device are preferably made of metal of a suitable character and thus willV last almost indefinitely.

While I have herein described the best embodiment ot my invention that I have so :tar devised, I donot wish to be limited to the exactv details of the construction shown. For instance, in making' an oval or ilat brush of this type, it is merely neces` sary to inake the proper changes in the shape of the parts andto secure the collar l2 to the head 2 by screws arranged to enable 'the collar to Clamp the flanges and l0 to the head, as above described.

Having thus described iny invention, what I desire to claim as new is: v

1. In' a fountain brush, the combination of a hollow head,- a handle extending` from one end of said head, a Valve block supported in said head, a brush body independent oi said block but having one end thereof abutting'. against said block, said body and block haying,l flanges overlying the outerend of said head, and a collar arranged to clainp the flanges of said body and blocl against the end of said head, said block having a passage therethrough for conducting liquid from said head into said brush body.

2. In a fountain brush, the combination ot a hollow head, a handle extending' trom one end of said head, a Valve block supported in said head, a brush body independent of said block but having' one end thereof abuttingr against said block, said body' and block having` iianges overlying the outer end of said head, a collar threaded on said headand serving to clamp the flanges of said body and block against the end of said head, a nipple projecting,r from said block into said brush body, said nipple and block having' a passage therethrough, a Valve controlling the flow of liquid through said passage, and an adjusting screw carried by said head and 'arranged to adjust said valve.

3. A brush body comprising' a bodyT of bristles, an inner tube around' which said bristles are disposed at one end of the body, an/onteisleeve encircling' the body of bristles at said end of the body, said bristles being secured irrnly between said tube and sleeve, andan attaching flange 'projecting laterally from the periphery of said sleeve.
