PAINTING APPARATUS.

SPEGIFICATION forming part of Letters Patent K0. 769,372, dated September 6, 1904. Application filed February 15, 1904:. Serial No. 193,647. (No model.) I

To all whom, it may concern;

Be it known that I, JOHN J. ALLnN,a citizen of the United States, residing at Portland,

pertains to make and use the same.

' My. invention relates to an apparatus for applying paint, whitewash, or like substance to surfaces by the action of hydraulic pressure; and it hasfor its object the provision of an apparatus of this character which shall be adapted fordealing with surfaces of considerable height in a simple and eflective manner and with a great reduction of labor and expense as ordinarily involved in such an op- Heretofore in all painting apparatus of this particular type air has been used as the impelling agent, and in these instances it necessitates the provision of-a pump or other air-compressing means, thus greatly increasing the expense of the apparatus.

It is the purpose of the present invention to provide an apparatus which shall be especially adapted for applying the paint by means of hydraulic pressure, in which case the apparatus may be connected directly to any ordinary water-main.

I T he invention is illustrated in the accompanying drawings, in which- Figure 1 is a vertical sectional view of the painting apparatus, and Fig. 2 is a plan view of the same with the top of the tank almost entirely broken away.

Referring to the drawings, A denotes a suitable tank or other receptacle of any desirable size and capacity for holding the paint or like composition and containing the water under pressure, said tank beingsufliciently strong to resist the pressure necessary to the ejection of the paint. The tank-is provided at its top with a charging-orifice a, closed by a screw-plug a,'and at the bottom with a discharge-pipeb, to which. is connected a flexible tube 0, provided at its other end with any desirable spraying-nozzle or other applying device. (Not shown.) The discharge-pipe b is provided with a valve or stop cock b for controlling'the'flow of the paint; but it will of course be understood that the spraying-nozzle may also be equipped with suitable valves which shall be under the control of the operator for temporarily checking the flow of the paint when desired and especially at a time when the operator a considerable distance from the tankfor instance, in coating surfaces of v considerable heightand at other times when it would be extremely inconvenient for him i to cut off the flow by means of the stop-cock Z). The impelling agent, which in the present inwater-main through the flexible tube cl, thence through pipes eandf, and finally admitted under pressure to the upper part of the tank through a number of branch pipes g. It will be noted that all of the branch pipes g are provided with upturned spouts for directing the water on its entry into the tank upward and away from the supply of paint. Owing to this arrangement of the inlet-pipes,it will of course be understood that the paint is not subjected to the full force of the streams of water issuing from the branch pipes g, and thus undue agitation of the paint by reason of the incoming water is prevented. As a further preventive of any undue agitation of the paint by the sudden force of the water as it enters the tank and also for the purpose of distributing the downward pressure evenly over the entire surface ofthe paint I arrange within the tank 'a floating disk, said disk being of a diameter a little less than the interior diameter of the tank, so that it loosely fits therein. The disk is preferably constructed of a body portion it, of wood, having embedded therein on opposite sides layers of cork '5 a" to give the disk suflicient buoyancy to always keep it afloat.

as shown at f, and it is to be noted that the water issuing from the branch pipes 9 will pass through all of these perforations, and thus exert an even pressure over the entire surface of the paint sufficient to eject the same from the tank. It is to be particularly noted that even in the event the tank should be only half filled with the composition the force of the streams of water issuing from-the branch stance is water, is carried from any ordinary Numerous perforations are formed in the disk,

pipes 9 would be broken and the water spread over the entire top surface of the disk and allowed to pass through'all of the perforations therein to evenly distribute the pressure over the entire surface of the said composition. The paint or other composition, as the case may be, being of a greater specific gravity than the Water and owing to the fact that in the present apparatus there is provided suitable means for distributing the hydraulic pressure at all times evenly over-its entire surface, it will necessarily follow that thepressure within the tank will force the paint out through the dischargepipe, where under the control of the operator it may be directed onto the surfaces to be coated, it being understood that the valves have been previously opened. It is to be further noted that the discharge-pipe b is provided with a pressure-gage 7:; of any wellknown type and that the tank has an ordinary sigh t-glass Z suitably attached thereto near its bottom, both of which being for obvious purposes. The tank is also provided near its bottom and preferably at a point to one side of the discharge-pipe I) with a drawoif cock m, through which the water may be drawn and afterward used, if desired, in mixing the next coating composition.

In carrying out my invention various modifications in the construction therein shown and described may be made, and I would therefore have it understood that I do not limit myself to the precise details herein illustrated.

Having thus described my invention, what I claim,is

1. An apparatus for applying paint or other composition to surfaces by the action of fluidpressure, comprising a receptacle for holding the composition and receiving the fluid under pressure, a discharge-pipe for the composition, and an inlet-pipe for the fluid having an upturned end located above the composition and serving to direct the fluid on its entry into the tank upward and away from the c0mposition therein, I

2. An apparatus for ap ilying paint or other composition to surfaces by the action of fluidpressure, comprising a receptacle for holding the composition and receiving the fluid under pressure, a discharge-pipe for the composition, an inlet-pipe for the fluid, and a plurality of upturned spouts connected to the inletpipe for directing the fluid on its entry into the tank upward and away from the composition therein.

3. An apparatus for applying paint or other composition to surfaces by the action of hydraulic pressure, comprising a receptacle for holding the composition and receiving the water under pressure, a discharge-pipe for the composition, an inlet-pipe for the water, and means within the tank for distrilniting the hydraulic pressure evenly over the entire surface of the composition.

4. An apparatus for applying paint or other composition to surfaces by the action of hydraulic pressure, comprising a receptacle for holding the composition and receiving the water under pressure, a discharge-pipe for the composition, an inlet-pipe for the water, and afloating perforated disk within the tank for distributing the hydraulic pressure evenly over the entire surface of the composition.

In testimony whereof I afiix my signature in presence of two witnesses.

JOHN J. ALLEN.
