" ATTORNEY Patented Dec. 7, 1943 UNITED STATES ATENT OFFICE 8 Claims.

This invention relates to new and useful improvements in a self-feeding paint brush.

More specifically, the invention proposes the construction of a self-feeding paint brush characterized by a casing having a paint passage extended from its top to its front face and carrying a paint container arranged to feed the paint from said container to a paint distributing mem ber mounted upon the front face of the casing.

Another object of this invention propose the provision of a valve Within said container and arranged in conjunction with the top end of the paint passage to control the quantity of paint which will be supplied to the paint distributing member.

A further object of the invention proposes mounting the casing upon the top end of a long handle in a manner to permit the casing to be conveniently manipulated for painting high inaccessible wall areas without the use of a ladder or scaffold.

It is a further object of this invention to provide the casing with paint spreading and finishing rollers mounted above and below the paint distributing member in a manner to smooth the paint and remove the brush marks from the surface of the paint.

't is a further object of the invention to prvide means whereby the paint distributing member may be automatically extended and retracted and controlled by the handle upon which the casing is mounted in a manner to permit the paint distributing member to be adjusted relative to the casing to seat solidly against the surface be ing painted.

For further comprehension of this invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which th various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a 1naterial part of this disclosure:

The self-feeding paint brush, according to this invention, includes a casing If) having a paint passage I I which extends from its top face downwards and forwards to the front face of the casing. A container I2 is mounted upon the top face of the casing I0 and is provided for the purpose of holding a quantity of paint. The container It. in the preferred construction is integrally formed with the casing III and is provided with a top opening I3 closed by means of a slidably mounted panel I l. One end of the panel It is provided with an upwardly extended handle it by which the panel I4 may be removed from the top of the container I2 to permit the quantity of paint within the container to be replenished.

A valve is provided for controlling the quantity of paint that will enter the paint passage I I from the container I2. This valve comprises a cylindrical valve element I6 located within the container I2 and which seats against the top end of the paint passage II. Trunnion elements I? extend through the end Walls of the Container 6 f. and rotatively support the cylindrical valve element I6. One side of the cylindrical valve element I6 is flattened and when aligned with the top of the paint passage I I permits a quantity of paint to enter the paint passage and flow down-- wards therethrough. One of the trunnions I'I carries a knob It by which the cylindrical valve element I6 may be conveniently rotated. The knob It carries a pointer I9 which registers on a calibrated scale 20 formed on the adjacent out side face of the end Wall of the container 52 to indicate the degree of alignment of the flattened side of th valve member It with the top end of the paint passage I I A paint distributing member 2! is mounted on the front face of the casing IQ. This paint dis-- tributing member is in the form of a brush having a back member 22 which seats within a recess 23 formed in the front face of the casing Iii. Set screws 24 are threadedly engaged through the end Walls of the casing It and engage the ends of the brush back 22 for securely mounting the paint distributing member ZI in position within the recess 23. A plurality of brush bristles 25 project from th brush back 22 and are adapted to engage against the wall 25 being painted. The brush back 22 is further formed with a passage 21 which connects with the bottom end of the paint passage II for the purpose of conveying the paint flowing through the paint passage i l to the bristles 25 of the paint distributing member 2|.

Means is provided for mounting the casing I8 upon the end of a long handle 28 to permit high inaccessible areas of the wall to be painted without the use of ladders or scaffold. This means comprises a bracket 29 mounted upon the back face of the casing ill and which is provided with a pair of superimposed inwardly converging threaded openings 38 into which end of the handle 23 is adapted to be threadedly engaged for securely mounting the casing It upon the end thereof. When the handle 28 is engaged into the bottom opening 39, high inaccessible places may be painted, and when the handle 28 is engaged into the upper downwardly inclined opening 30, low inaccessible places may be painted without requiring bending over.

Paint spreading and finishing rollers 31 are mounted above and below the distributing memher 2!. These rollers 3i are provided with outwardly extending trunnion elements 32 which rotatively engage brackets 33 extending forwardly from the ends of the casing ii The surface of the rollers 3! are serrated for the purpose of spreading the paint and for simultaneously removing the brush marks from the paint spread by the brush bristles 25. Thus the rollers 35 also act as stippling members to permit the painting and stippling to be simultaneously accomplished by a single brushing operation.

lhe operation of this form of the invention is as follows:

To fill the container 2 with paint the valve member 55 is rotated to a position in which it will close the top end of the paint passage i, and the panel It is removed from the top of the con tainer i2, permitting the paint to be used upon a wall to be passed into the container through the open top 53. After the container i2 is filled with the desired quantity of paint, the panel i4 is returned to its engaged position with the container l2 to close the open top thereof. The valve it is opened to a desired degree by turning the knob l3 and watching the movement of of the handle 23 and by means of the handle the entire device is raised to a position in which the paint spreading and finishing rollers 3| and the distributing member 2! will be seated against the vertical wall 28. By means of the handle 28 the entire device is moved vertically along the wall causing the bristles 25 of the paint distributing member 25% to spread a film of paint upon the wall 25. Following the bristles the spreading and finishing rollers 2! will pass over the film of paint and assist in the spreading operation and remove the brush marks from the surface thereof.

In the modification of the invention shown in Figs. 8 and 9, the construction of the self-feeding paint brush is similar to that previously described, except for the construction and manner of using the paint distributing member 2!. In this form of the invention the paint distributing member 2! has a back member 22 which engages within a recess 23 formed in the casing In. A sponge rubber member 25' is seated within a cavity 46 formed in the front face of the back member 22'. The sponge rubber member 25 acts in the nature of a brush for spreading the paint which is conveyed to it by the aligned passages II and 21.

Means is also provided for extending and retracting the distributing member 2! relative to the vertical wall 26 so as to cause the front face of the sponge rubber member 25 to seat solidly against the vertical wall. In this form of the invention the casing H] carries a horizontal stud M which is rotatively supported and which has its front end threaded to engage a complementary threaded opening 42 formed in the back face of the back member 22' of the paint distributing member 2!. The horizontal stud M is formed with a beveled gear 12 which meshes with a pair of beveled gears 43 mounted on the inner end of socket members 39' which are adapted to receive the end of the handle 28.

The socket members 31] carry set screws 44 which are adapted to engage against the end of the handle 28 and securely lock the end in position within the socket members 33'. The socket members 36' are rotatively supported on the casing l9. Thus the handle 28 may be rotated relative to the casing for rotating the stud ll to cause the paint distributing member 2| to be moved into and out of the recess 23 in the casing Id. Springs 45 operate between the back face of the back member 22' of the paint distributing member 2| and the base wall of the recess 23 to urge the paint distributing memher 2! outwards relative to the casing it] requiring that the stud M be used to move the paint distributing member 2! into the recess 23.

The bottom end of the paint passage II has forwardly extending tubular extensions 46 which slidably engage into the back end of the passages 21 formed in the back 23 of the paint distributing member 2| for conveying the paint from the container 12 across the open space between the back face of the paint distributing member 2! and the base wall of the recess 23.

In other respects this form of the invention is identical to the previous form and like parts are indicated by like reference numerals.
