DEVICE FOR THE PRODUCTION OF COMPRESSED OXYGEN FROM LIQUID OXYGmI.

Serial No. 496,763.

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that I, ADOLF Mussnn, a. citizen of the German Republic, residing at Frankfort-on-tl1e-l\2ain, Germany, have invented certain new and useful Improvements in Devices for the Production of Compressed Oxygen from Liquid Oxygen (for which I have filed an application in Germany, lllarch 26, 1919, Patent No. 337,942), of which the following is a specification.

During the war plants for the production of liquid oxygen for blasting purposes have been installed in numerous mines. These plants, which must be very simple, supply the oxygen only in liquid state and they do not comprise an arrangement for the reevaporation of the liquefied oxygen.

In the same works compressed gaseous oxygen is used for autogenous soldering and cutting in the working of the blast furnace for the melting away of the top holes, for rescue apparatuses and other purposes. The gaseous oxygen mustv either be produced in the works in a special plant for the production of gaseous oxygen or it must be got from the outside.

In many cases the plant for the production of the liquid oxygen could have a greater output than the quantity of liquid oxygen which is required for blasting purposes. In such cases it is an inconvenience that the oxygen cannot be compressed to be used for the above mentioned purposes.

' This invention has for its object to obviate this inconvenience. The liquid oxygen is first gasified in an evaporator through which it is sucked from. the compressor. Only after the gasification the compression is eifected in the compressor from where the compressed oxygen is forced into the steel bottles or other collecting vessels or into the distributing conduits.

In order that the mvention ma be clearly understood, I shall proceed to escribe the same with reference to the plant which is diagrammatically shown b way of example on the only figure of t e accompanying drawing.

The vessel 1 insulated by vacuum contains the liquid oxygen'which has to be transformed into compressed gaseous oxygen. The end 2 of a serpentine tube 3 dips into the vessel 1, the oxygen being sucked through this serpentine tube by the compressor 4t. "\Vhen flowing through, the serpentine tube 3 which is surrounded by the warm atmospheric air, and which can eventually be further heated by previously heated air, electrically or in any other convenient manner in order to produce a more eilicacious evaporation, the liquid oxygen evaporates and arr ves in gaseous state at the suction Valve 5 of the compressor 4.

The gas is compressed in the compressor 4 and forced through the pressure valve 6 and through the conduit 7 into the steel bottle 8. A spiral 9 can be inserted in the conduit 7 to produce agreater movability.

The gaseous oxygen can be forced into a distributing conduit instead of being forced into the steel bottles or to any other point where it is to be used. For the serpentine tube 3 any other device for the eva oration of the oxygen could be substitute The method can be applied also in connection with other liquefied gases.

I claim Device for producing compressed oxygen from liquid oxygen comprising incombination a receptacle for the liquid oxygen, a compressor, an evaporator consisting of a serpentine tube connected at one end with said receptacle and at the other end with said compressor, said serpentine tube being in heat exchanging contact with the atmosphere, and a discharge pipe at one end connected with the compressor and at the other end adapted to be connected with a steel bottle to be filled;

In testimony whereof I affix my signature in presence of two witnesses.

ADOLF Masses.
