CLAMP AND VALVE OPERATING MEANS FOR PAINT BRUSHES Filed Feb. 6, 1933 Patented May 22, 1934 UNIT as CLAMP AND VALVE OPERATING MEANS BOB PAENT BRUSHES Application February 6, 1933, Serial No. 655,452 In Australia February 15, 1932 2 Claims.

I ficult of access, and in many cases obviating the employment of a ladder or platform which otherwise would be necessary.

To attain this object I employ a relatively long handle, which may be tubular, having upon its end a clamping device in which the paint brush is fixed.

A valve for regulating the flow of paint is closed by a spring and is operated by a spring returned pull, or pressure, piece upon the end of a rod 0. passing downwardly within or alongside the handle and operated by a lever fulcrumed thereupon.

The clamping device is comprised of two sections opposing each other upon the end of the handle and drawn together by a bolt provided with a wing nut.

The clamping device forms a plurality of sockets one or other of which is placed upon the handle whereby a brush or the like implement is 30.jheld at a desired angle relative thereto.

A rod slidable longitudinally within or upon the outside of the extension handle has, at its upper end, a pressure head adapted to contact with and operate the valve of the paint brush, the

I rod passing through a socket actuated by a sleeved spring and having guide fingers or a cup or the like adapted to maintain the pressure head i n alignment with a press knob upon the spindle of the regulating valve.

The press knob is associated with the brush used in connection with this kind of painting apparatus and pressure upon it operates the valve through which paint passes to the brush.

At its lower end the rod passes into a cup, wherein it may be fixable by a set screw, the cup being upon one arm of a bell crank lever fulcrumed upon a ferrule upon the extension handle.

The opposite end of the bell crank lever is rashioned to be pressed by the hand of the painter.

If desired an additional section for lengthening the handle may be connected to the first extension handle by grip ferrules or the like.

The lengthening section will have slidable upon 5 it a further section of the main operating rod to which it will be comiected by a socket and set screw or other means.

To catch surplus paint, which might fall from the brush head and cause inconvenience, the brush head is surrounded by a collecting cup, and a waste pipe led therefrom to inside the tubular handle, or alongside it, the waste paint being collected in a conveniently located receptacle.

My invention is illustrated in the accompanying drawing whereinz- 511 Fig. l is a side elevation showing the brush clamped at right angles to its handle.

Fig. 2 a part elevation showing the brush parallel with the handle and Fig. 3 a perspective view of the clamping device.

Where the same parts occur in the several figures they are indicated by the same reference numerals.

The handle 1 has upon its upper end a clamping device comprising a grip socket 27 and a plurality of sockets 28 all formed of two corresponding sections 2 and 3 which are drawn together by a wing nut 4 upon a bolt 5, passing through the handle and through the two parts.

Paint is delivered under pressure from a receptacle by a pipe 6 to a distributing brush 7 carried in a holder 8 fixed in grip socket 27, the handle being secured in one or other of the sockets 28 or" the clamping device according to the desired positien of the brush relative to the handle.

A valvefor regulating the flow of paint has a stem 9 having a press knob 10 received between guide fingers 11 upon a socket 12 constituting a pressure head through which passes a slidable rod 13 having sleeved upon it a coil spring 14. located between the socket and an eye 15 projecting from handle 1.

The lower end of the rod is stepped in a cup 16 upon one arm of a bell crank 17 pivoted at 18 in an extension from a ferrule 19 adjustable upon handle 1.

The opposite arm 20 of the bell crank is adapted to be manually operated.

The handle is in two sections socketed together at 21 and for lengthening purposes the rod is in two parts the end of one part having a socket 22 which receives the end of the other part.

To catch surplus paint the brush head is surrounded by a collecting cup 23 from which a draw pipe 24 leads to a conveniently located receptacle.

When it is desired that the brush be parallel with the handle as shown in Fig. 2 a bifurcated lever 25 is'interposed between the pressure head and the press knob 10.

One arm of the lever is fixed upon the brush holder 8 by a screw pin 26, the opposite arm rests upon the pressure head while the end of the lever bears against the press knob 10.

When the brush is to be used at the angle shown in Fig. l the lever 25 is removed.

I claim:-

1. For the purpose indicated in combination a handle, and a clamping device thereon comprising a grip socket, a brush secured therein, means for supplying paint to the brush, a valve controlling the flow of paint, a press knob upon the stem of the valve, a slide rod, a pressure head thereon, a socket through which the rod slides, fingers upon the socket adapted to receive the press knob, a spring adapted to keep the pressure head in contact with the press knob, and means for actuating the slide rod.

2. For the purpose indicated in combination, a handle, and a clamping device thereon comprising a grip socket, a brush secured therein, means for supplying paint to the brush, a valve controlling the flow of paint, a press knob upon the stem of the valve, a slide rod, a pressure head thereon, a bifurcated lever interposed between the pressure head and the press knob, a socket through which the slide rod passes, fingers upon the socket adapted to receive one arm of the bifurcated lever, a spring adapted to keep the bifurcated lever in contact with the press knob, and means for actuating the slide rod.
