, provide an apparatus for the above purpose and improved.
which will be 'simpliecL efficient, strong, durable. conveniently and economically manufacturable,
Heretofore, the operation ofl apparatuses of this type at times entailed dangers produced .by inadvertently overloading the paintcontaining receptacle thereof with too great an air pressure, which sometimes resulted in explosion. It is` therefore a further object of the invention to remedy the aforesaid disadvantage, and to provide an apparatus possessed of inherent means which will obviate possibility of such danger and which will be furthermore conveniently and eiliciently operable. I
A still further object of the invention is to provide an apparatus forthe above purpose, which will compel the operative to stand by it during the loading of its paint containing receptacle with air pressure, butin which the feed of air pressure will automatically cease upon the operative leaving the apparatus.
A still further object is to provide an apparatus for the above purpose, the requisite working parts of which will be maintained as a unit, for ready and convenient attachment thereoiI interchangeably to any one of a plurality of paint containing receptacles.
Other objects and advantages will hereinafter appear.
In the accompanying drawings- Fig. 1 shows a plan view of the paint spraying and applying apparatus of the invention. v
Fig. 2 is a side elevation of the apparatus nipple 'I threads into thepipe 6, and the joint thereat is sealed b'y a nut and gasket 8 threaded about'sald nipple and against the tank-wall 4, and a union 3 joins thevfnipple I with a nipple lil threaded to a cross II carrying a coupling I2 to which is attached a hose I3 leading to a usual spraying gun I4. To cross I I is connected a valve I5 to which is in turn joined a T-iltting I6 provided with a coupling I1 for a hose I8 leading to the gun I4, and said fitting carries another coupling I9 for a hose 20 leading to a compressed air source 2|. In the tank-wall 4 is formed an opening 22 tapped toreceive a nipple 23 which is secured and sealed in place to said wall by a nut and gasket 24, and to said nipple is joined a union 25 connected `lto a cross 26 carrying an elbow 21 to which is connected a pressure gauge 28. To the cross 26 is connected a valve 23 having a nozzle 30. The valves I5, 29- are oper- 15 by actuation by the single handle 34 common m to both of them. Thus, operating the link 33 to dispose the handles 3|, 32 to a vertical position, as viewed by the dash and dot lines, Fig. 1, simultaneously `closes the valves I5, 29, While similarly returning said handles to a horizontal u position opens both of the valves.
To 'each of the crosses II, 26 is connected an. elbow 35 which are in turn connected by a rod 36, Fig. l, and said crosses are also connected by -bars 31, l38, in which manner all of the dependlo ing parts' connected to the tapped opening 22 of tank-wall 4 and all of the depending parts connected to the opening 5 are bridged together i by said rod and bars and are rigidly secured to constitute a unit, which may be therefore inu terchangeably connected to any one of a plurality of paint containing tanks 2, by merely threading in of the nipples 'I, 23, and nuts 8, 24, as illustrated in Fig. 3.
In the Autilization and operation of the appan ratus, the aforesaid unit constituting it is secured to a. paint containing tank 2', and the hose lines "I3, I8, 20 are coupled to the apparatus as shown in Fig. 1. The valves' I5, 29 are then opened simultaneously by the operatives one hand manipulating the link-handle 34. Thereupon, compressed air flows from source 2I through hose 20, tting I6. valve I5, lcross II, and through union 9 nipple 'If and into pipe 6, from the lower terminal of which it is inl0 jectecl into the painting uid, as illustrated in Fig. 2, in which manner the -uid becomes agitated and thoroughly admixed of all its constituent substances, as required for the spraying process. The air passing through the liquid H,
' apparatus, any attempted feeding of compressedr 3' thereupon fills the space II thereabove and is exhausted through nipple 22, union 25, and the This manner of circuiting the air-- .malns in spacel 39 thereabove and raises the pressure in the tank, as becomes observable by the gauge 28. As soon as the tank pressure reaches a required amount, the operative swings back the link handle 34 and thereby simultaneously closes both of the valves I5, 29. The painting liquid 3 is then siphoned through tube 6, union 9, cross Il, and from the latter through hose I3 to Ithe spraying gun Il.
-It will be noted that in the operation of this air into the tank 2 automatically opens the exhausting valve 29 and thereby prevents formation of pressure within the tank until the operative deliberately closes the nozzle 30 withhls nger, that while performing the latter his eyeis directed upon the gaug'e28 to ascertain the required pressure produced within the tank, and that the subsequent simultaneous closing of both valves J5, 29 with the single vhandle 34 Vshuts on the incoming compressed air completely, from 'which it will be evident that any danger of formation of excessive pressure within the tank is obviated. Should the pressure become low within the tank, the same may be replenished readily bysimilarly operating the handle il and applyingthe ingery to nozzle 30, to. remix the iluid and restore the pressure. A safety'valve Ia'connected tothe tank 2 in its roof 4 serves at all times to prevent development oi undue air pressure within the tank over its prescribed cay'pacity.
Variations may be resorted to within the lscope of the invention, and portions of the improvements may be used without others.
Having thus described oui-invention, we claim:
1. A paint spraying apparatus having the combination of a closed receptacle for the painting liquid, a pipe leading from the upper partof said receptacle into the liquid, a pipe leading from said first pipe for connection to a compressed air source, a pipe leading from said receptacle f or connection to a paint spraying gun, a valve in said second pipe for admitting and shutting' oii' the air from said source. an air exhausting pipe leading from the upper part oI- said receptacle, a
valve in said exhausting pipe, and a link joiningI both of said valves for simultaneous andinterdependentoperation of both of said valves.
2. A paint spraying apparatus having the combination of`,a closed receptacle for the painting liquid, a pipe leading from the upper part ofsaid receptacle into the liquid, a pipe 'leading from said'flrst pipe for connection to a compressed air source, a pipe leadingirom .said receptacle for connection to a paint spraying gun, a valve in said second pipe for admittingand shutting off the air from said'source, an. air exhausting pipe leading from the upper partof said receptacle, a valve in said exhausting pipe, and means joining both 'of said valves for simultaneous and interdepedent operation of both of said valves.
