the like. In such apparatus the liquid is fed or forced to the paint gun or other discharging or dispensing device under pressure and luid under pressure such as yair 1s also delivered to said paint gun and the like to atoinize the liquid and to apply it to the surface being treated. This Huid pressure and pressure on the liquid being discharged must be regulated in accordance with various factors. One important factor is the character of the liquid being applied. Another 1mportant factor is the type of paint gun or other discharging or dispensing device used.

By way of example, certain paint guns are known as the inside mix type, that is, where the liquid is broken u and atomized within the nozzle and be ore being discharged from the nozzle. Another type is called. the outside mix type, in which the paint is discharged from the nozzle and then broken up and atomized by streams of air under pressure. The former type is also called the low pressure type because much less air pressure is necessary to atomize the liquid inside of the nozzle.

This invention is adaptable for use in `connection with paint guns of yboth types as well as other kinds and types of discharging and dispensing devices and also with liquids havving a. Wide variety of characteristics.

A material part of the invention comprehends a single main control valve and a plurality of adjustable and automatic pressure regulating and reducing valves which intertercommunicate each other and to and 1931. Serial No. 531,839.

discharging or dispensing device and is adapted to regulate and adjust the pressure of the pressure fluid such as air,'passing into the gun. The first mentioned reducing valve is, of course, for the purpose of regulating and adjusting the pressure upon the liquid in the tank or container. The main valve is preferably mounted so as to be moved to two positions, in one position air under pressure is irst passed through one reducing valve and thence tothe paint gun or other discharging device, part of the air, however, being diverted through the other reducing valve to the interior of the tank or container. Under these conditions the air pressure in the paint gun must always be greater than the air pressure uponthe liquid, and of course greater than the pressure under which thel lquid is discharged from the gun. This is for the reason that the pressure iiuid in its path to the tank or container passes through both reducing valves in series, and therefore the air pressure in the tank or container can never be greater than the air pressure passing directly to the paint gun, but must always be less due to practical operating conditions.

In the other position of the main valve the pressure fluid passes to the reducing valve controlling the pressure of air in the tank or container, part of the compressed air being diverted from this reducing valve yback to the other reducing valve which controls the pressure of the air to the paint gun. Under these conditions the pressure of the air in the tank or container mus-t always be greater than the pressure ot' the atomized air delivered to the paint gun, asthis part of the compressed air passes through both reducing valves in series.

For convenience sake, the various parts and connections embodied in my invention may be mounted upon a lid or cover, called a pressure head, for a tank or container and thus provide a simple way of embodying this invention for practical use. The disclosure is of a construction of that type, but it is to be expressly understood that the combination of structural elements may be used for various other purposes than paint spraying and the like, and in various other ways.

' To the accomplishment of the foregoing and such other objects asmay hereinafter appear, this invention consists in the construction, combination and arrangement of parts hereinafter described and then sought V various changes may be made in practice within the scope of the claims Without digressing from my inventive idea.

Figure 14 represents a horizontal (section Referring to the drawings, the numeral 1 rdesignates a lid or cover for what is termed a pressure tank for holding a suitable quantity of liquid or fluid adapted to be applied or dispensed under pressure. This lid or cover is provided with a plurality of ears or lugs 2 whereby it is adapted to be connected by any suitable means .such as the pivoted bolt 3 and. Wing nut 4 to the tank or container 5, as shown in detail in connection with Figure 7.

The various connections and fittings for supplying a fluid under pressure to the interior of the tank or container so as to place the liquid therein under pressure and for supplying Huid to a discharge or applying meniber, such as a paint spray brush or the like, are all mounted upon said lid or cover 1. Several arrangements are shown in this application and attention will lirst be directed to that shown in Figures 1 to 5 inclusive. The fluid under pressure customarily used is compressed air which is obtained from any suitable source and passes through a filter 6 to a conduit 7 which communicates with a transverse port or passage 8 provided in the tapered body 9 of the main operating valve, which transverse port or passage 8 communicates with the radial port or passage 10 extending at right angles from the approximate middle thereof, see Figures 2, 3 and 4 particularly. The valve body 9 is also provided with an inclined diametrical port or passage 11 which is preferably located below the port or passage 10 and in vertical alinementtherewith, the port or passage 10 being referably inclined, see Figure 2 particuarly. The valve body 9 is rotatably mounted in a suitable casing 12 and provided preferably on its top end with the operating handle or lever 13 and also provided with a stud or suitable projection 14 adapted to engage suitable shoulders or abutments 15 provided on said valve casing 12, see Figures l, 2 and 5. The cooperation of this stud or projection 14 with the shoulders 15 limits the movement of the valve body or member within its cas-4 16 and each extension 16 is provided at or 1 near its end with a reducing valve construction 17. These reducing valve constructions are preferably standard and include a body 'portion 18 and a tubular or cylindrical housing 19 secured thereon with a flexible dia- ISC remise phragmi held between the body 18 and the housing 19. 'A block or abutment member 21 rests on top of the diaphragm 2() and pressure is applied thereagainst by means of spring 22, the other end of Whichl engages the block or abutment member 23 against which a regulated pressure is applied by means of the screw member 24,' thus alording means for adjusting the tension of the spring 22 and also the pressure upon the diaphragm 2f).

rEhe screw member 24 extends up Within the bored end of the casing 19 and is prov vided in itsend with the squared socket 2li which is adapted to receive a complementerily shaped end on the handle or adjusting member 2d. llhis handle or adbiusting member is removable at will as its tit in the square socket 24 is merely a tight sliding tit.

or encountered in maintaining the tension of the spring 22 and theI pressure on the diaphragrn 20 at the desired figure, due tol attempted readjustment or unnecessary manipulation of the parts, it may be at times desirable to adjust these reducing valves in a vlined position either before the apparatus leaves the factory or when in use, the adjustment of course being made by competent and experienced men conversant with the proper adJustment to give best results under the operating conditions. ln order to take care of this condition l provide the lock 24, the bail 24h of Which'may be passed through suitable openings in the extended end of casing 19 of the reducing valve. Of course this lock is ap lied after proper adjustment is made. rPhe ook has been shown on the right hand reducing valve of Figures l and 2 only, but it is to be understood that it is applicable to the left hand reducing Valve as Well.

Ther-valve assembly in the reducing valve construction preferably includes'a yoke member 25 the upper end 26 of which bears against the under side oi the diaphragm 20. rlhe lower end 26 of the yoke is reduced and slidably positionedV in recess 27 formed in the removable bottonil cap 27, a spring 28 being positioned in said recess and bearing against said lovrer end 26 of the yolre so as to maintain `the yoke member in contact with the diaphragm. yThe upper part oi the yoke member 255 has a slidable engagement with the sides of opening 29 formed in the partitio'n 3G, this partition being provided with a plurality of openings 31 to establish coinrnunication between the under side of the diaphragm and the interior of the body oi"- the reducing valve as a Whole. A valve disc 32 is mounted in proper position in the lower part of the yoke member 25 and adapted to close the valve seat 33 formed on the depending end ci? a projection 3e extending Within the reducing valve body as a Whole.

Each of said lateral extensions 16 is provided vvith a plurality of ports or passages 35 and 36, the latter being positioned in substantisl alinement with the former and above the saine and in proper spaced relation so as to register with the ports or passages'land 11 in the main valve body. ln the position of that valve shown in Figures 1, 2 and At, the two ports or passages 35 and 36 to the left communicate respectively with the ports or passages ll and l() of the valve. 'in this position the port orpassage l1 establishes a connection between the port or passage 35 in the left hand extension 16 and the port or passage 36 inthe right hand extension 16. l.When the valve body is turned substantially 180 to the right as shown in Figure 3, the port or passaA e l0 of the valve body communicates Wit the port or passage 36 or the right hand extension 16 and the port-or passage 1l In the event that difficulty isanticipated of the valve body establishes communication between the port or passage 35 of the right hand extension and the port or passage 36 of the left hand extension 16.

' The body portion 18 of each reducing valve l? is of course provided with a suitable outlet` the one to the right being designated 37 and the one tothe lett being designated 38, the former being for the purpose of receiving a pipe or conduit to supply fluid under pressure to the interior ot the tank or container and upon the liquidi-herein and is therefore termed the liquid connection, and later being for the purpose of receiving a pipe or conduit to supply fluid under pressure to the discharge or dispensing device and therefore termed the air connectiolu lt is therefore seen that the main operating valve 9 may be adjusted to two operating positions and that in each position the pressure fluid passes in series through each of the two reducing valves. ln the one case, that is, Where the handle is inthe left hand position shown in Figures l, 2 and 1l, theuid pressure passes first through the reducing` valve l? to the lett which of course is -adiusted to give the desired air pressure to the paint gun or other discharge or dispensing device. 'Part of this fluidl under pressure passes through the left hand port or `passage 35, the port or passage i 11 in the valve 9 and the right hand port or passage 36 to the right hand reducing valve 17. rhis is of course adjusted so es to give the desired pressure upon 'the liquid in the container. in this position the pressure upon the liquid in the container must always be less than the duid pressure being delivered to the gun or other discharge .or dispensing device. lt can never be greater because it has to pass through the two reducing valves in series.

When the valve 3 is adjusted in its other position as shown in Figure 3, the reverse condition exists. rl`he duid pressure is iirst conducted to the right hand reducing valve which is adjusted at the pressure desired for the liquid in the tank or container. Part of the iiuid pressure then passes to the leit'ha'nd reducing valve which is adjusted in accord-V ancewith the lower pressure desired for the paint gun or other dispensing or discharge device. In this position this last mentioned pressure can never exceed the ressure upon the liquid in the tank or container. In both positions it-is seen that the fluid pressure passes through both reducing valves 1n series and that there is never any independence but always a dependant relation between these two valves and the ad'ustment of the air discharge and liquid disc arge pressures respectively. A

The detailed connections for supplying the fluid pressure to the paint gun or other discharge or dispensing device include a'nipple 40 connected tothe left hand discharge outlet 38, anelbow- 41, a.- coupling 42, pipe or con- -duit 43. and a four-way coupling 44 having a vertical member rigidly secured to the top of the lid or cover for supporting urposes. The other vertical member 44 is a a ted to receive a pressure gauge 45, and 46des1gnates a connection for the fluid pressure conduit leading to the paint gun or other discharge or dispensing device.

Fluid pressure is supplied to the interior of the tank or container from the outlet 37 on the right hand by means of nipple 47, elbow 48, coupling 49, and pipe or conduit 50, one end of which connects vwith the horizontal arm 51 of a T member 52, the lower vertical arm of which passes through the top of the lid or cover to supply pressure fluid to the interior of the tank or container, the upper vertical member 53 being adapted to receive the ressure gauge 54. A safety valve is connected at 55 to avoid excess pressures within the interior of the tank or container. The lid or cover l is tapped in another place to receive the elbow nipple 56 which isvprovided with a coupling 51 having a threaded member 58 to be connected to a pipe, conduit or hose for conducting the liquid material under pressure from the tank or container to the liquid conduit of the paint gun or other discharge or dis nsing device. The tank or container is pre erably provided with a pipe 59 (see Figure 7) which extends from a point near the bottom thereof to the tapped opening communicating with the elbow ni ple 56.

The modified structure shown in Figures 6, 7 and 8 will now be described. The lid or cover, tank or container and means for securing the former to the latter are the same as Cpreviously described. Fluid such as air un er pressure is supplied through filter or strainer 6l through elbow 62 to the T member 63. This T member has one of its lateral ends closed by means o plugmember 63a, see Figure 8', so that the pressure fiuid is permitted to pass in one direction only through ve" e 6e, conduit 65 which. leads to a pressure pling 67.

' When the supply standard make and will not be described in detail. It is understood vthat the pressure passed by the valve may be varied :by means of adjustment and maintained constant. The outlet side'of the pressure reducin valve 66 is connected to t e nipple 68 which is attached toa four-way member 69, see Figures' 9 and 10 for details. The vertical top arm of member-69 is rovided with a g'au 70 and the downwardly extending verticarm communicates with the interiorof the tank by means of a connection passing through opening 71 in the lid orcover. In Figures 9 and 10 the horizontal arm of the four-way member 69 is designated 72 and receives the ball check valve 73 normally held in place against the end of nipple 68 by means of spring 74. A three-way valve 75 is mounted within said four-way member 69 and provided with a diametrical port or passage 76and a radial port or assa'ge 77 extending at right angles there rom. In addition tothe ports or passa es leading respectively to the source of fluid pressure supply, the gauge 70, and the opening 71 intothe tank, the four'- way member 69 has the fourth port or passage 7 8 leading to the atmosphere. The valve 75 has the handle or lever 79 for operating thesame. `When the parts are in the position shown in Figure 9, air will be supplied through the connection 68 to the interior of the tank or container and also to the gauge. of air under pressure is shut oil and it is d ired to stop o ration, the valve 75 may be turned 180 wliich will place the interior of the tank or container in communication with the atmosphere and permit the surplus pressure to be thus dispersed. In this position, of course, the check valve prevents the return of pressure back into the reducing valve 66. Furthermore, when the tank is under atmospheric pressure the paint line may be cleared out by closing the nozzle opening of the' paint gun by means of a linger or otherwise and admitting air pressure thereto which forces any remaining paint hack into the tank.

The lid or cover is tapped at a suitable place to receive an elbow nipple 80 which is provided with a suitable connecting member 81 adapted to be connected to a pipe, hose or otherconduit leading tothe liquid discharge passages of the paint gun or other discharge or dispensing apparatus. The liquid tube 59 is connected to the same opening in the lid or cover as clearly shown in Figure 7 and previously described, so as to supply liquid under pressure said nipple 86 and connection 8l to 'the gun.

I have described the fittings ctending to he from the T member 63 (referring I Figure 6)., and will new describe those tending 'the ieft of the m member 63.

-Sid or cover is aise te* 'to provi` sie i s pps-d n 89 to receive a niy is connected to the plug 63a oy means of the coupling 84. The plug 63a is connected to the air conduit-,85 and is provided 'with an `enzgfular port or passageway 86, the vertical -outlet side of the pressure reducing Valve 92 is connected oy means of a nipple 93 to a :four-Way member Sb the horizontal arms of which forni part .of the air conduit Jfor supplyinrr air under pressure to the paint gun or other discharge device. rl`he upper yertical arm of the four-Way Ymember 9d is adapted to receive a suitable pressure gauge 95 While the lower or downwardly extending vertical arm is secured to the iop of the lid or cover to serve merely as a support. A safety valve 96 may loe mounted on top of the cover to avoid excessive pressures.

The operation of this construction is siniple and readily understood. Air under pressure regulated by the reducing valve 66 is admitted 'to the interior of the tank or con- I tainer Aand operates to force the liquid out through the liquid tube 59 und connections 80 end 8lv to the paint gun or other discharge device. tainer constitutes a reservoir for the pressure fluid and supplies the same 'through connections 83, 849 86, 87, S8, 85, SQ, 90 and 9i to the reducing or regulating Valve $2 and thence to the peint gun or other discharge device. @i course, in this construction the air or fluid pressure upon the'liquid must always 1ne greater than the oir or iiuid pressure delivered to the peint gun and the reducing Valves operate in series, et all timesa Figures ll to l5 inclusive? show e modilied construction ci the main operating yell/e and reducing valve esseinlolr.

Of course it is t be understood that inheach instance the reducing or regulating valves may be adjusted so as to ve the desired pressure for each purpose ut that in each position or adjustment o valves are arranged in series and independent of each other.

It is to be understood that while I have shown auges to register the pressures being used in connection with tires, and that lthe ordinary air pressure gauges used for deter'- mining pressures in tires may be used to ascertain air ressures in this apparatus.

It is to .noted that the two reducing valves are preferably combined with the main operatin valve in one valve assembly and that neit er one of said reducin valves can be removed, and also that both o said reduc- -cti ing valves must (Iiperate whenever the apparatus is `used. urthermore, regardless of whether the a paratus is being used for an internal mix ow pressure), or external mix gun, one of the reducing valves is dependent upon and subordinate to the other reducing valve. When used for the inside mix, the air pressure to the gun can never be greater than 4 thefliquid pressure. When used with the outside mix gun, the pressure of the li uid can never be greater than the pressure o the air. In each instance, the lower pressure is subject to the regulation of both reducing valves operating in series. l As the main valve is operated by one'lever or handle, the operation of this apparatus is materially .simplified as no time. is lost in opening and closing valves, a movement to either one or the other operating position being sufficient to start the operation of the apparatus. Of course in an intermediate position, the main line pressure is entirely shutoff. Air leaking and valve packing are' eliminated, and the release valve empties the air rapidly from the tank and prevents the flow of air into the tank besides facilitating cleaning of the apparatus.
