method of an apparatus for spraying or atomizing materials such as liquids or liquid compositions, and particularly for spraying liquid compositions such as paints by the use of gas stored in containers which title preferably though not necessarily porta le.
The object of the invention is to provide an improved method and apparatus of this character whereby the atomizing or spraying can beefi'ected'by a constant stream of pressure gas. Some preferred embodiments of my invention will now be described with reference to the accompanying drawing in which; Figure 1 is perspective view showing a portable machine when not in use.
Fig. 2 is a perspective view showing a portable machine in use, said machine employing safety heating means and hereinafter described.
f Fig. 3 is a section taken through theheating means of Fig. 1.
Figs.4 and 5 show fragmentary views of modifications.
Fig. 6 is a horizontal section taken through a well-known regulating device employed in the present apparatus.
In accordance with the method of the present invention, which will be described with reference to the preferred forms of apparatus herein illustrated, I use as the atomizing or spraying medium, carbon dioxid or or other suitable gas under pressure, stored either in liquid or gaseous form in a container which is preferably portable, so that the container can be readily transported to the position where it is to be used to supply the gas for atomizing purposes. In carrying out my improved method, it is immaterial whether or not the gas contained in the container is inliquid or gaseous form, inasmuch as this feature of my invention provides for the issuing of the carbon dioxid or the like from the container in gaseous form, and by applying heat evenly to the stream of issuing gas before it has an oppor- 7 Specification of Letters Patent.

tunity to expand to a substantial extent, as
by passing it through a coil arranged in a liquid bath at a temperature above normal atmospheric temperature and preferably as high as possible, I have found fromactual practice that the gas issuing from the container will not tend to freeze in the outlet of the container and moreover, when passed through a pressure reducing valve or regulating'device, in orderthat its pressure may be reduced to that required at the atomizing or spraying tool, it will not freeze at the point of expansion. The gas may or may not be re-heated in similar manner, and is then' conducted to the spraying tool or receptacle 1 for the material to be sprayed, or both to the receptacle and the tool. In addition to heating the issuing stream of gas in this manner, I sometimes find it desirable to heat the container itself, either directly or indirectly or by means of-a liquid bath or by applying steam or hot gases against the container, and this heating of the container may or may not be effected by the same heating device which heats the liquid bath.
I will now proceed to describe my invention with reference to the preferred form of apparatus illustrated in Figs 1, 2 and 3.
Referring to said figures it will be noted that the apparatus comprises a platform 10, mounted on wheels 11 and 12. Riveted or otherwise suitably secured to the platform 10 are two vertical angle-iron frame members 13, braced by vertical side plates 14 which serve to support the axis of wheel 12. The wheels 11 are mounted in inclined bars 15, bolted at 16 to the uprights 13 and connected by the pins 17 to the side bars 18, secured at 19 to the uprights 13. Across-bar 20 connects the two uprights 13, and a panel 21 is secured between the said uprights and serves as a support for the shelf 22 and the regulating means hereinafter described. Handles 23 are pivoted at 19 to the uprights 13 and are formed with the openings 24 adapted to take over the pins 17 so that said handles can be swung from the position shown in Fig. 1 to that of Fig. 2, and
. bath 33 contained in tank 34 mounted on shelf 22 and heated by any suitable heating means, the device illustrated in Fig 1 being a well-known commercial type of kerosene burner 35. The gas leaving the coil 32 passes up through pipe 36 into the regulating means 37 and associated gage and 1nd1- cator 38,mounted on panel 21 and illustrated more particularly in Fi 6, where the pressure of said gas is suitab y reduced; the extent of this reduction can be regulated in well-known manner by means of the handle 39. The outlet 40 of the regulator 37 is connected with a pipe 41 leading to coil 42 which is also immersed within the liquid bath 33, and connected with the other end of this coil'is a pipe 43 leading to a valve 44 which controls the passage of gas from said pipe 43 to pipe 45 to which is connected a flexible pipe 46 (Fig. 2) preferably made of rubber or the like, and lead ng to the paint receptacle 28. The flexible pipe 46 is connected with the interior of the paint receptacle by the T-connection 47 which provides a branch 48 leading to the regulating means 49, which is similar to the regulating means 37 and adjustable by the milled head 50, whereby the pressure oniop of the paint can be regulated to suit the requirements for use. end of said T-connection 47 to the painting tool or brush 52 of well-known kind, whereby the compressed gas issupplied to said tool.
The paint under pressure, forced by the compressed gas on the top of the paint rein the container 26 is then permitted to leave ceptacle 28 through the outlet 54 passes into the flexible pipe 55 leadingto the painting tool, where the atomization of the issuing paint is effected by the pressure gas from the pipe 55.
The operation of the improved painting apparatus will now be described. The paint receptacle 28 is removed from the hook 27 and placed upon the ground, as shown in Fig. 2, and the burner 35 is lighted in order to heat the liquid contained'in the tank 34. The carbon dioxidcor like gas under pressure said container -by opening the valve 29, which allows said gas to pass through pipe 31, coil 32, pipe 36, pressure regulator 37, pipe 41, re-heating coil 42, pipe 43, valve 44,
The pipe 51 leads from the other pipe 45, flexible connection 46 to paint receptacle 28. The gas passing through the pressure regulating valve 49 to the top of the paint receptacle forces the paint in said receptacle at the desired ressure through the pipe 55 into the painting tool, and the compressed gas passing through the T-connection 47 to the ipe 51 also passes through the painting tooi under the required pressure to atomize the paint. It will be understood from the above that the gas reaches the heater without substantial expansion, so that no freezing occurs during the passage of the gas through the pipe 31 to the coil 30. Care should be taken not to use too wide a pipe.
The devices which are herein referred to as pressure regulating valves are of wellknown character, and in the example of the regulator 37 herein shown, as illustrated in Fig. 6, comprises a casing 56 formed by two members 57, 58 between which is suitably secured a diaphragm 59 upon which is mounted a seat-supporting member 60 provided with a seat 61 covering the small opening 62 at the conical end 63 of pipe 64 lead ing from the elbow 65 for theadmission of gas. Bearing on the other side of said diaphragm is a spring 66 the tension of which can be regulated by means of a nut 67 mounted on screw shaft 68 in the casing and provided with the operating handle 39. A pipe 69 at the top of the casing which cannot be seen in this figure, but is visiblein' Fig. 3, leads to the indicating device 38 (Fig. 3), and the outlet 40 conducts the gas at the reduced pressure to the pipe 41 (Fig. 3).
While" this is a preferred form of pressure,
regulating or reducing valve, it will be understood that the invention contemplates the employment of any suitable or well-known form of device of this character.
The container 26 may contain either car bon dioxid or like gas under pressure or in liquified form, and may or may not beprovided with well-known siphon means for leading the carbon dioxid to the outlet valve 29. w
In the modification shown in Fig. 4, steam generated by heating the water bath 33 is applied against the side of the container 26 in order to heat the contents of the container during the painting operation. In this modified form, the tank 34 is provided with a cover 35 which serves as a support for one or more nozzles 36 controlled by the valve 37 and which is adapted to direct the steam generated in the tank 34 against the side of. the container 26*. combustion gases from the burner 38 pass through the opening or openings 39 in the supporting shelf 22 and panel 21*, and are directed against the sides of the container 26, thereby heating the contents of the container as well as the tank. A slide 40 with an opening 41 is arranged between the shelf In Fig. 5, the {hot suitable plug of 22 and panel 21 and regulates the passage of hot gas through the openings 39".
In painting the interior of certain buildings, in order to comply with fire regulations and for the general purpose of safety, I may use a Davy lamp for the purpose of providing the necessaryheating. Fig. 2 shows the use of such a lamp, which is provided with the usual perforated screen Alternatively, as shown in dotted lines in Fig. 5, I may employ an electrical heating coil 7 0 immersed in the liquid, and supplied with heating current from a battery 71, which may be carried upon the platform of the portable painting apparatus, the current from the battery passing through the electrical connections 72, 7 3 controlled by switch 7 4. In place of using a battery as a source of current supply, it will be obvious that the connections 72, 73 can be connected to electric mains, or to the ordinary electric light sockets ina house or the like by means of a a well-known character. In conjunction with the use of an electrically heated coil or the like, instead of using a bath of water or the like to maintain an even temperature for heating the coils 32, 42, I may employ a bath of toluol, parafiin or the like, which present important advantages in that a maximum temperature can be maintained without requiring any attention on the part of the operator, and there will be no' evaporation of the liquid contents of the tank 34.
I prefer to heat the gas in the liquid bath as much as possible, as this "materially assists in getting the best results While the improved apparatus has been clescribed herein with reference to a method in which the carbon dioxid or the like leaves the container in gaseous form, it will be understood that my improved apparatus is suitable for use in cases where the carbon dioxid leaves the container in liquid form.
While my improved method and apparatus have been described herein with reference to the spraying or atomizing of paint, it will be understood that I contemplate the use of this apparatus with obvious modification for any kind of atomizing or s raying operation, such as the atomizing o metals or sand blast apparatus, and it will be obvious that many changes will be made in the herein described method and apparatus without departing from the spirit of my invention and the scope of the appended claims. I
