APPARATUS FOR MAKING OXYGEN.

Specification of Letters Patent. Patented D 28, 1909,

Application filed July 20, 1909. Serial No. 508,616.

To all whom it may concern:

Be it known that I, GEORGE VON AoH, a citizen of the. United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Makin Oxygen; and I do hereby declare the fol owing 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 eing had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved apparatus for Withdrawing the oxygen from the air and delivering it into suitable storage tanks or' receptacles.

Theapparatus is designed to be made so that it can'be usedby a physician to manufacture his own oxygen supply, and it can be installediin hospitals and the like to provide a quick and simple means of securing oxv en when needed.

T e device embodies further a furnace in 'which the air is heated before it is purified and is again heated to withdraw the oxygen therefrom, the excess heat from the burners in the furnace heating the air on its way to the urifying apparatus.

'1 1e invention is illustrated in the accompanying drawings, in which- Figure 1 is a diagrammatic view of the apparatus, and Fig. 2 is a section of the furnace taken on line 2,2, in Fig. 1. F ig- 3 is a top View of one form of retort employed in the-ap aratus. Fig. l is a section of a modified firm of retort, and Fig. 5 is an elevation partly in section illustrating" another arrangement of the retort and pipe coils which are used in conjunction therewith.

Theinlet pipe takes the air from any; point 'where it is desirable to install the pipe and conducts it to a cylindrical heater or rewhich is installed at the top and on the inside of a furnace 12 which will be described hereinafter, and the receptacle 11 receives the excess heat.- from burners 13 which may be "of any usual construction, butare preferably gas burners. After. being heated the air passes from' the receptacle 11 to a pipe 14 down which it passes, passing a valve 15 and into a box or similar structure -'16 which box is either made up of or lined .w'th sheet iron and contains lime- The box isair tight and the moisture in the air is from which it absorbed by the lime, the best arrangement. being as shown in Fig. 1 with the pipe'14= passing to near the bottom of the box 16, the air being conducted from the box 16 by a pipe 17 which in turn leads to near the bottom of a holder '18. The holder 18 contains caustic soda and on this account is usually lined with lead. The pipe 19 conducts the air, which is now nearly purified to the proper degree of purity, and leads it into the pipe 20 through valves 45 and 741 passes into the pipe 21 which. is connected to the pump 21 which is a. pressure and vacuum pump, according to the desire of the operator, and is used to draw the air through the receptacle 11 and the connectin pipes and through the box 16 and the holder 18, andthen pass it out through the pipe 22 into a reservoir 23, the pipe 22 being provided with'a valve 24, the uses of which will be described hereinafter.

The reservoir 23 has a gage 25 thereon and has an outlet pipe provided with a pressure regulator 26, which regulator permits the air passing into the remainder of the system to have a predetermined pressure, and it has been found that the most satisfactory pressure is about seventeen pounds. The air then passes into a tube 27 which I fill withsponges to further dry theair and to prevent oil from the pump from being transmitted, and then through the pipe 28 into the cylinder or similar structure 29 which is in turn provided with a pressure gage 30 and is adapted to be filled with lime. A pipe 31, provided with a valve 32, then conducts the air from the cylinder 29 to a regulator 33 similar to the regulator 26. A pipe 34 then conducts the "air to the retorts which are in the furnace below the receptacle 11 and passes along in the shape of a larger pipe 35 and then is passed back and forth, horizontally in the furnace, to form a coil 36, which coil is red hot, when the device is in operation, and will heat the air to a very high temperature. The air is thus well heated for its passage through the pipe 37 into the vessel 38, which vessel will bev described more in' detail hereinafter, and. is desi ned to provide a receptacle for barium oxid or a similar substance or substances which are adaptedto draw the oxygen from the air and absorb it when'the air and the 'material are heated. The. vessel is red hot from the flames of the burners 13 and the absorption of the oxygen permits the nitrogen to pass out through the pipe'42, past the valve 39 and. escapethrough the'check valve 41 from which it either passes into the atmosphere or can be retained in a suitable receptacle,- A pressure gage 40 keeps the operator posted on the pressure in the coil and the vessel in the furnace.-

When 'suflicient oxygen is retained or ab sorbed by the barium oxid in the vessel 38,

the valve 37 is closed, th'us shutting off the I vessel from the coils-in the furnace, The

gen

pump 2l 'is now used to draw the oxy from the vessel 38, thepi e taking theoxygen from the pipe 42 t rough the valve 44'which has been opened, having been previously shut, the valve 45 in turn being shut after being opened in thepreviously 'de scribed operation. In emerging from: the

pump, the oxygen, instead of passing through the pipe 22, takes another channel, because the valve 24 is closed and the oxygen is forced through a pipe 43 either into. the pipe 46 to a suitable gasometer 47',- or

. through the pipe 48 into a tank 49 where it.

is stored and by means of which it can, be transported when transportation is necessary, the tank 49 being ,any of the usual commercial tanks now employed for this purose. p The vessel 38 which is placed underneath the pipes as shown in Fig. 2 is preferably made of boiler iron or a suitable metal that is adapted to withstand the variations in Y temperature towhich the vessel is rangedon opposite ends of the vessel, and

subjected, and is formed preferably oblong, andin oross-section is elliptical. The vessel is disposed in the furnace so that the heat can pass around the sides thereof and is pro vided with sleeves or short pipes 53 which form flues which permit a more ready and A complete heating of'the vessel. To prevent collapsing or buckling of the vessel when under pressure or vacuum and heat at the the. insertion of barium oxid .or similar chemical to the vessel, the formation of the vessel permitting a thorough heating of the oxid and forming the means for withdrawing the oxygen from the air. The pipe connections for the pipes 37 and42 are arpreferably on opposite sides, so that the air is compelled to pass over the whole body of the barium oxidv before it issues from the vessel.

A- suitable inlet 52 is provided for the ,installation and insertion of a pyrometer which is shown installed in Fig. 1, the pyromregulations eter 66 being provided with the usual fiexi ble connection 67 which in turn is connected to al. lndicatorfifi whereby the heat in the I vessel. can be determined tope'rmit of ts When the oxygen is being drawn from the vessel, through the pipe42, tbs gage 40 is shut 01f from inea nso f its valve-the check valve 41 automatiealiy closes, eenne'ctee- "to the pipe by having its valve opened, ih "this v'va'ythe vacuum can be determined.

thepipe' by and the vacuum gage 65 is If desired, I may make theves'sel 38 as shown in Fig. 4, being made in halves which are provided with the flanges, 56, these flanges being riveted closely together to form an air tight closure, the vessel being connected from side to side by suitable tie-rods or bolts 55, In 5 I illustrate a modified form of'arrangmg the; vessel and the pipes in a furnace, the furnace 68 being provided at its bottom with any kind of gas, V

or other burner 64, and between but above the burnersis arranged a' vessel 57 similar to tie vessel 38 of the previous structure, the

vessel. 57 bein adapted to receive barium mud or a sum ar substance.- From a. pipe 58 air is fed from a coil of pipe 59 between I which and one wall of the vessel'57 a flue is formed, the coil 59 being fedby a pipe 60 which leads-from another coil 61 on the opposite sideof the vessel 57 from the coil 59, thereby forming anotherflue. The coil 61 receives its supply from the usual purify-' ing apparatus. A pipe 62 is adapted to lead 1 the oxygen from the vessel 57 As shown in Fig. 1.1 may, if desired, i11- v stall a pipe 69 leading into the pipe 34, which pipe 69 leads-froma suitable boiler or source of steam supply and-is designed to inject steam along with theair when sodium;

manganate is used in the vessel instead of barium oxid.v

When oxygen has been stored in the gammaeter, and it is desired to,place-it into the receptacle 49, the valve 74 in pipe '19 is closed and the valve 44 is closed, but valves 45 and 7 3 are open, and in this way oxygen can be p the pipes 72, 19'and 20 and through the and the oxygen-passes through the pipe 48 and the Valve into the receptacle 49.
