PRESSURE-REGULATOR,
Specification of Letters Patent.
Application filed November 18; 1818. Serial No. 2633002 To all w hom it ma concern:
Be it known t at I, WILLIAM F. GRA- DOLPH, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State. of Ohio, have invented a certain new; and useful Pressure-Regulator; and I do'hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference "being had to' the accompany ing drawings, and'to the characters of refer paint receptacle and jat'the air brush underencemarked thereon, whichform a part of this specification.-
This invention relatesto fluid pressure control means for use in connection with spraying apparatus, and more particularly for use in connection with paint spraying apparatus in which liquid paint is c0ntained in a substantially air tight receptacle and is forced therethrough by air pressure to an air brush or spraying device, which is also supplied with air under pressure to assist in discharging the liquid therefrom in spray form, as well understood in the art.
'In the use-0f apparatus of this class,-it is customary to maintain the air within the While the invention in its broader aspect is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings,
in which, w
Figurel is a side elevation of an apparatusembodying the invention, with the receptacle withwhich it is associated in section. Fig. 2 is a top plan view thereof.
Fig. 3 is an enlarged central vertical section of the pressure regulating means with parts in full. Fig. 4 is an enlarged sectional detail of aportion ,thereof. Fig. 5 is a top plan view of the body member of the apparatus with the end caps removed and a part broken away. Figs. 6 and 7 are sections thereof taken, respectively, on the lines 6, 6" and 7, 7 in 5, and Fig. 8 is anend view thereof. f
Referring to the drawings, 1 designates a closed air tight receptacle for the paint, or other matter to be sprayed, 2 the removable top closure member therefor, and 3 the pressure regulator head or body member,
which isthreaded ,at its bottom-in an openmg provided therefor in the closure member.
The head' 3 is provided in its'icentralpor- "tionwith a main pressure chamber 4 and'at the 0 posite sides of said main chamber Patented Oct. 14, 1 919.
with t e'ftwo Secondary r reduced Pressure chambers 5'and 6. Valve controlled1com munlcat on is provided betwen-.th'e main chamber Land each secondary chamber; In? the present instance, the wall betweenthel main chamber 4: and each secondary cham-- her is provided with an opening 7 in which is threaded a bushing 8 forminga 'seat. for
a check-valve .9- and a guide for its stem 10,
and also forming a communicating passage; 11 between the main and respective seconu dary chambers. The valve 9 :seats under main chamber pressure against the inner end of its bushing 8, and its stem projects. outs tive secondary chamber. Thefvalve is norward through the bushingi'nto'the respc-L mally held seated by a-coiled tension spring" 12, which encircles the outer end portion of 1 the valve stem and has itsinner end-thrust against the outer end of the bushing 8 and its outer end-thrust against atension adjusting nut 13 on the outer end of the stem.
The outer side of each secondary pressure chamber 5, 6 is closed by'a diaphragm 14,
which is clamped to the respective end of q the head 3 by a cap 15 screwed thereon. Eachcap 15 contains a spring chamber 16 open at its inner .end to the diaphragm 14,
and a coiled compression spring IL? is dis-,
posed in this-chamber with its axis substantially alined with the adjacent valve stem '10 and With its inner end provided with a plunger 18 in thrust contact with the central portion of the diaphragm in opposition to the valve stem 10, which is intended to have contact with the inner-side of the diaphragm, as shown.
A tension adjustin screw 19 is threaded through the outer end in the present instance, extends entirely through the head 3, crosswise thereof, and has valve controlled tubes and 26 leading from its opposite ends to respective air brushes (not shown) to supply air under predetermined pressure thereto, so that either or both of the air brushes may be used at the same time.
A liquid tube 27 is threaded into "the bottom of the head 3 and extends downward therefrom into the receptacle 1 to near its bottom, and communicates at its upper end through a passage 28 with a cross passage 29 in the head. Valve controlled liquid tubes 30 and 31 lead from the opposite ends or the passage 29 to the air brushes to whichthe respective air tubes 25 and 26 lead.
A passage 32 extends down through the head .1 with its lower end in communica tion with theinteriorof the'receptacle l. A safety valve 33 is threaded into the upper end34 thereof and. a relief valve 35 is.
threaded into a side opening 36 thereof.
The air pressure in the receptacle is de-' termined by a gage 37, which is threaded into a socket 38 in the head top, which socket is in direct communication with the head. through the passage 32 and a bypass 39 connecting said socket and passage. The
air pressure in the secondary chamber 6 is" determined by a gage 40, whlchconnects with said chamber through an opening 41 in the head top.
In order to cause the air pressure which enters thereceptacle 1 from the chamber 5 to agitate the liquid, a tube 42 extends trem the passage 23 down into the receptacle and terminatesnear the bottonnthereof in a horizontally-disposed coil or angled portion 43, which is perforated to discharge the air under pressure in a plurality of streams into the bottom portion or the liquid contained in the receptacle. The coupling 44 between the tube 42- and head passage 23 is provided with a check-valve 45 in the air supply passage, which permits only an outward fiowcf fluid therethrough, and said coupling is also provided with a lateral passage 46 in communication with the upper portion of the receptacle interior and nor;
mally closed by an inwardly opening check valve 4?. This check valve is adapted to open under receptacle pressure when the aeiasee pressure in the coupling passage above the valve 45 is less than the pressure in the receptacle, which condition would be present if the main supply valve were closed and i the stored up pressure in the receptacle not relieved by leakage or an opening of the relief-valve 35. The purpose ofthe checkvalve 45 in the connection between the air chamber 5 and interior of the receptacle is to prevent air pressure within the receptacle from causing a backing up of the paint I threugh the tube 45 and into the chamber 5 when the pressure within said chamber has been relieved by a closing of the main supply valve.
In the use of my invention, it will be understood that the pressure in themain chamber 4 of the regulating head is substantially the same as the pressure at the source of supply, due to the valve passage connecting the same being open, and that the springs 17 normally press the diaphragms 14, with which they coact, inward, and
maintain the check valves9 open due to the a closing of the respective valves may be J regulated to a nicety by adjusting the tension of the respective springs'which is accomplished by turning the screws 19. The pressure in the chamber 5 is regulated to suit the pressure desired in the receptacle 1 and is'determined by the indicator gage 37, which is in direct connection with the interior of the receptacle through the socket 38, by -pass 39- and passage 32 in the head. The pressure in the chamber 6 is regulated to suit the air pressure desired at the air brushes employed and is determined by the gage 40, which is in communication with the chamber 6.
I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit I an air brush in connection therewith, of a.
pressure regulator head having a main pressure chamber in communication with a source of fluid ressure supply, two secondary pressure 0 ambers each having communication with said mainchamber and one having communication with-the interior of said receptacle and-the other having communication with the air brush, a-diaphragm in each secondary chamber, a valve normally closing the communicationbetween each secondary chamber and the'main chamher and having its stem .in connection with the diaphragm whereby an inward 'movement of the diaphragm efiects an opening means coacting with'the outer side of each diaphragm to resist an outward valve closing movement thereof, a pressure gage carried by said head in direct communication with the interior, of the receptacle, and a pressure gage carried by the head in direct communication with the secondary chamber having communication with the air brush.
