ALFIO RAPISARDI, OF BOSTON, MASSACHUSETTS.

I FOUNTAIN BRUSH.

Application filed. `IEebiuary 6, 1924. Serial No. 690,979.` i

- 1o all/whom 'it may conc-em Be it known that I, ALFio RAPISARDI, a subject of the King of Italy, residing at Boston, in the county of Suffolk andkState of Massachusetts, have invented certain new and useful Improvements in Fountain Brushes, of which the following is a speci fication.-

This invention relates to brushes, and more particularly to brushes of the fountain type designed especially for use by painters, decorators, and the like.

It is the chief object of the invention to devise a brush of the general character above indicated which can be cleaned more conveniently and thoroughly than prior constructions, and particularly to devise a solid, substantial and serviceable construction which can be manufactured economically. The invention also aims to prevent paint, or other liquid being applied, from running back along the brush on to the workinans hand in decorating ceilings or doing other overhead work. j j

. The nature of the invention will be readily understood fioin the following description when read in connection with the accompanying drawings, andthe novel features will be particularly pointed out in the appended claims.

Referring now to the drawings, j

Figure 1 is a vertical, cross-sectional view of a brush embodying the invention in a preferred form, some of the parts beingV shown in elevation;

Fig. 2 is a cross-sectional view of the brush shown in Fig. 1, the plane of crosssection being at right angles to that of F ig. 1; 5

Fig. 3 is a cross-sectional view of another embodiment of the invention;

Fig. 4 is a cross-sectional View at right angles to Fig. 8; and

Fig. 5 is a bottom View of a part of thev brush shown in Figs. 3 and 4, illustrating the manner in which the drip catcher is secured in place. i

The construction shown in Figs. land 2 comprises a brush consisting of a back or block 2 of wood, metal, or any other suitable material, with a body of bristles 3 secured thereto in the usual manner. As shown, the back has a central extension or tongue 4 around which the bristles are arranged and against which they are clamped by a sleeve or binder 5. The upper ends of or some other adhesive, which aids in securing them to the back 2. The brush shown is ofthe sol-called flattype, as will be evident from an inspection of the draw? ings.

This brush is removably supported in a holder consisting of a hollow head 6 and a hollow handle 7 extending from said head, the upper end of the handle'being equipped with a lunion 8 by means of which the haiidle may be connected to a hose or tube which supplies paint, varnish, or other liquid thereto. provided with a long narrow opening to receive the upper end of the brush back 2, and in order to form a tight joint between these parts the brush back is grooved, as indicated at 9, to provide a marginal seat that receives the lower end of the head 6. Preferably the head 6 and handle 7 are made of some relatively light metal, and in order to prevent the sides of the head from bulging or springing outwardly, three braces 10, 11 and 12 are located within the head, extending across-the space therein from one sideto the other, and have their vopposite ends riveted to the wallsofthe head. Two screws 14 and 16 extend through holes in f the upper wallof the head 6 and are threaded into the brush back 2, as clearly shown in Fig.r1, so thatby tightening these screws the brush back is drawn firmly against the lower edge of the head 6 and is securely held in this position. Packing washers 17 may be used under the heads of the screws to form tight joints atthese points and thus prevent the escape ofthe paint or other liquid contained in'the head. Preferably, although not necessarily, the screws 14 and 16 are guided through holes formed in the braces 10 and 12, since this facilitates the entrance of the screws into holes in the brush back when4 the parts are being assembled.

The paint or other liquid within the head 6 is conducted into the body of bristles through a passage k18 formed through the brush back 2. A valve l19 controls the flow of liquid through this passage, a seat for this valve being formed in the upper surface of the back 2. The valve is guided partly by an extension 20 lthat projects into the passage 18, and partly by a stem 21 which projects through a hole formed in the central brace 11. A coiled spring bears on the lower side ot the valve and tends to lift it oil its sca t,- thus holding the stem ill in Contact with. the lower end oit an adjusting screw 23 which is threaded through the Wall of the head 6. Consequently, by turning this screw, the lon' ot paint or other liquid into the brush can be adjusted ver),`- accurately.

lit n'ill non be evident that whenever it is necessaryv to clean this brush the screws leland lo can be hacked out. thus releasing the hack Q and permitting the removal of the entire brush unit troni the liolder. These parts can then be washed conveniently and thoroughly and reassembled, or a nen' brush unit may be inserted in the holder in place of the one tornierltY used. This arrangement has the further advantage of permitting the use of dillerent brush units with the same holder, and these units may diti'er from each other substantially in characteristics. so that the inlplement can easily be changed to suit the requirements of the work which is to be done.

Figs. a 4 and 5 show a somewhat different construction which is adapted espeasiallj,Y for painting overhead, decorating ceilings` and the like. In this arrangement the brush unit Q', 3 is constructed substantially as in Figs. l and but the head of the holder is somewhat different in shape from that above described and is provided with an ear 2C, Fig. el, to which a handle socket or tiiiture 27 is piroted. The brush unit is held in the holder by se 'en's ll and 16. and the valve arrangement and its adjusting mechanism are essentially like those shown in l and In this construction. however, a drip catfli r 2S provided, This attachment of a gutter which is split longitudinally, the two split sections being scoured together and clamped on `the holder 25 hy' screws, one of which is shown at 29, Fig.

In decorating ceilings and doing other overhead work, there always a tendenc)Y for the paint, or other liquid being used, to flou' back past the hase oit the brush and down the handle. This is very annoying to the Worlnnan, particularly in warm weather. Any action of this character is eil'eetuallv prevented by the drip catcher or gutter which collects the drip and prevents it from running downwardly upon the outer surface of the brush holder.

lVhile I have herein shown and described the best embodiment ol my invention that l have so tar devised, l do not wish to be liniited to the exact details el the constructions shown.

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

l. A fountain brush cinnprising, in combination, a hollow metal head, a handle connected with said head, a brush back shaped to tit in the end of said head, ay body of bristles valve, and means for adjusting said valve.l

2. 'fountain brush comprising, in combination, a hollow metal head having a long narrow opeiiing in one end thereof, a handle connected with the opposite end oi" said head, a iiat brush .fitting in said opening in the head and comprising a brush haelt and a body o l bristles projecting therefrom, a plus ralitjv of ln'aces extending across the space within said head from one side thereof to the other, a plurality of screws extending through said hea d and braces and projecting into said brush back. said screws serving to draw said brush iirmly into migagenient with said head and te hold it securely in its operative relationship to the head, said bach' having a passage therethrough for the Hon' ot liquid :troni said head into said body ot bristles` a valve controlling the lion of liquid through said passage, and adjusting means itor said valve.

2l. A Yfountain brush comprising, in combi nation, a hollow metal head having an opening in one end thereof, a handle connected with the opposite end ot said head, a brush l'itting in said opening in the head and conn prising a brush back and a bodj,Y of bristles projecting therefrom, a brace extending across the space Within said head, and a screuextending through said head and brace and projecting into said brush back to hold said brush in its operative position in said head.

ALFI() RAPISARD.
