1 Claim.

This invention relates to fountain brushes and has for an object to provide a brush having a pressure equalizing chamber adapted to supply the bristles with liquid such as paint under uniform pressure throughout the width of the brush through rubber ducts which yield with the bristles and which will not work through to the surface of the brush but will remain surrounded by bristles so that the paint is applied uniformly to the surface to be painted.

A further object is to provide a fountain brush having a handle and a bristle element provided with a back removably attached to the handle so that replacements of worn bristle elements may be made when necessary.

A further object is to provide a fountain brush in which the handle is shaped to conform comfortably to the operators grip and carries a control valve within convenient reach of the operators ngers so that the flow of paint may be easily controlled.

A further object is to provide a device of this character which will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacricing any of the advantages of the invention.

In the accompanying drawing forming a part of this specification:

Figure 1 is a side elevation of a fountain brush constructed in accordance with the invention.

Figure 2 is a top plan view of the brush shown in Figure l.

Figure 3 is a longitudinal sectional view of the brush, drawn to large scale and taken on the line 3-3 of Figure 1.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, I0 designates the back of the brush member, the same being provided with bristles I I. The bristle member back is substantially rectangular in contour and may be formed of wood or other material. The back I0 is provided with a plurality of rubber ducts I2 which are tapered at the lower ends to provide nozzles I3 which extend between the rows of bristles and yield with the bristles when the brush is being manipulated so as not to become exposed laterally beyond the bristles. The rubber ducts are formed integral with a rubber facing I4 which is secured to the upper surface of the back III. The rubb'er ducts open through the facing I4.

The bristle member is removably receivable in a handle I 5 which is substantially rectangular inv longitudinal section and cross section and is of such height as to be conveniently grasped in the operators hand. The handle is preferably in the form of a metal casing having side walls IS, a bottom wall II, a top wall I8 and end walls I9. The side walls and end walls 'extend downwardly below the bottom Wall I'l, see Figure 3, to provide a socket which snugly receives the wood back III of the bristle member. The end walls are provided with lugs 20. Angular brackets 2I are secured by screws 22 and 23 to the lugs 20 and to the end faces of the wood back III of the bristle member. When the screws 23 are removed, the bristle member may be detached from the socket of the handle for replacement when the bristles become worn, and also the bristle member may be removed for inspection, repairs and cleaning when the screws 23 are removed.

A plurality of pipes 24 are disposed in the casing forming the handle I5. The pipes project through openings in the bottom wall I1 of the casing and enter the rubber ducts I2 of the bristle member, see Figure 2. The pipes are bent toward each other in the handle to be bunched and enter an extension 25 at one end of the top of the handle, see Figure 1. The extension is adapted to enter the crotch between the thumb and forenger of the operators hand and promote a firm grip of the hand to prevent slipping of the handle from the hand. The pipes open through the top wall 26 of the extension. The extension itself may be received in the space between the thumb and index finger of the operators hand to form a hand rest and permit the fingers and thumb of the operators hand firmly gripping the handle I5 to manipulate the brush.

A funnel shaped liquid chamber 21 is disposed exteriorly of one side wall I6 of the handle and the upper end of the chamber is provided with a lateral extension 28 'which extends over the top wall 26 of the extension 25 of the handle and communicates with the pipes 24 through a plurality of ports 29, see Figure 3. The extension 28 of the liquid funnel forms a chamber from which liquid is delivered uniformly to all of the pipes 24 to be supplied to the rubber ducts I2.

A valve casing 3D is secured to the aforesaid side wall I6 of the handle and is provided with a nipple 3I which enters the constructed lower end of the funnel shaped chamber 21 and is also provided with a nipple 32 which enters the outlet end of a paint or other liquid supply pipe 33 which may be connected to any suitable source of supply under pressure by a hose 34. A plug valve 35 is rotatably mounted in the valve casing and is provided with a pendulum valve handle 36 which always holds the valve open and which is moved by the operators thumb or linger to close the valve to any desired extent or to completely shut off the liquid supply, when desired, during manipulation of the brush.

Since the operation of the parts has been detween the thumb and forenger of the operators hand when gripped upon the casing to prevent slipping of the casing from the hand, a bristle member having a back removably secured to the handle and having bristles extending from the back, resilient ducts opening through the back and extending into the bristles, pipes housed in the casing and communicating with the ducts, a funnel shaped liquid chamber disposed on the side of the casing having a lateral extension at the large end extending across the top of said extension of the casing, a liquid supply pipe connected to the lower end of the funnel shaped chamber, and a valve in the lower end of the funnel shaped chamber having a weighted handle forming a pendulum normally holding the valve open and adapted to be engaged by the operators hand to close the valve.

JOHN BATTLE.
