this application filed February 9,

1916. Serial No.77,357.

To all whom it may concern: I

Be it known that I, WILLIAM A. HALL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Making Motor-Fuel, of which the following is a specification.

This invention relates to an apparatus for the production of a motor fuel suitable for use in automobile engines by the process described in my copending application Serial No. 3955, filed January 23, 1915, of which the present case isa division, and which ias now matured into U. S. Patent N 0. 1,175,910.

An example of an apparatus embraced within the scope of the present invention is shown in elevation (partly in section) in the accompanying drawing which forms a part of this specification.

In said drawing 1 shows a pump for introducing the oil under considerable pressure through the superheating coil 2, which may be heated by waste heat arising from the furnace 3, and which pipe coil 2 is connected in series with a coil of vertical piping 4, which may be of a diameter of 1 or 14} inch pipe (although the diameter of this pipe is not essential which pipes are heated by means of suitable burners 5, to any desired temperature, for example 540 to 600 C., more or less. The length of the pipe comprising the coil 4 is preferably about 320 feet, although this may be longer if desired.

At 6 I show a pyro meter placed between the coils of the pipes 4, for measuring the temperature.

Connected to the outlet end of the piping 4 is a pipe 7, preferably having therein a throttle valve 8, which leads to the lower part of a first preliminary condenser 9, which may be filled with checkerwork, for example composed of pieces of pipe or other shapes, as shown at 11, and the condenser 9 may be surrounded by a coolingjacket 10. At 12 is shown a pipe for drawing ofi' any material condensed in the condenser 9.

The pipe 13 leads the gases and vapors from the upper end of the condenser 9, to a second preliminary condenser 14, which may be similar in construction to the condenser 9. From the bottom of this condenser a pipe 15 serves to carry ofi any liquid condensed use. From the upper to the fact that portion of the condenser 14, a pipe 15 leads to a trap 16, in which a portion of the mist carried by the gases and vapors may separate out, and be. withdrawn through the pipe 16 into the condenser 14. From the upper portion of the trap 16, a pipe 16 carries the gases and vapors to the inlet side of a suitable compressor 17, in which the gases and vapors are condensed to a suitable pressure after which they pass while under pres sure through the pipe 18, condenser 19 and 20, the condensate collecting in tank 21, the uncondensed gases being drawn olf by pipe 22, and the motor fuel being drawn oil through pipe 23, for any desired subsequent purification.

24 illustrates thermometers placed in the upper ends of the towers 9 and 14, for showing the temperature of the gases and vapors leaving these towers.

The present application is also in part a continuation of my copending application 824,194, filed March 12, 1914, and 829634 filed April 4, 1914.

It will be noted that the valve 8 acts as a pressure-reducing valve, that is to say this valve is preferably set so higher pressure in the coil 2 and the retort 4, than is maintained in the preliminary condenser 9. Thus, without limiting myself to the particular pressures described in my prior cases above referred to, I may employ a pressure of to 90 lbs; per square inch in the decomposing coil, about atmospheric pressure in the preliminary condensers, and then may raise the pressure by the compressor to 75 or 100 or 125 lbs. 7

'While I have shown the two condensers or towers 9 and 14, as forming the two parts of a preliminary condenser, I call attention any suitable structure of preliminary condenser may be employed, and I do not limit myself to the use of a preliminary condenser comprising two towers. a What I claim is 1. In an apparatus for converting oils of higher boiling. points into oils of lower boiling points, the combination of a decomposing retort comprising a 'series of vertical as to maintain a loops, means for maintaining a pressure of 'sure;fa preliminary condenser, means for passing the gases and vapors from said retort to and through said preliminary condenser, means for compressing the gases an? vapors leaving the said preliminary condenser, means for further cooling the compressed gases and vapors, and means for maintaining in the decomposing retort, a pressure materially above that in the preliminary condenser.

2. An apparatus comprising a pressure pump, a tubular decomposing retort asepted to contain fluids under several atznos pheres pressure, a preliminary condenser, a compressor and a second condenser, all arranged in series, in the order stated, and connections therehetween, and means for maintaining in the decomposing retort, a pressure materially above that in the preliminary condenser.

3. An apparatus comprising tubular decomposing; retort adapted to contain fluids under a pressure or several atmospheres, a filled preliminary concenser, a compressor and a second condenser, all arranged in series in the order stated, and connections the e oetivecn, the connection hetw en the said decomposing retort and said preliminary condenser being provided with a pres sure-reducing valve.

ii pressure-producing device, atubular decomposing retort adapted to he continuously operated under a pressure oi several atmospheres, a preliminary condenser, a compressor and a second condenser, all arm, l 1- ranged in series in the order SofotGCL connections therehetween, niea s 1 in one rStOrl/ v vd the amount of gases and vapors allowed to pass through such connection, and for maintaining a higher pressure in the decomposing retort than in the preliminary condenser.

5. A pump, a preheating coil, a tubular retort, a pressure-reducing valve, a preliminary condenser, a compressor, and a second condenser adapted to be operated under pressure, all arranged in series in the order stated, l

6. A pressure-inainta-ining device, a decomposing retort adapted to be operated under a pressure of several atmospheres, a preliminary condenser capable of being 0perated at a pressure below that used in said retort, a compressor and a condenser haveooling means, arranged in series in the order stated, and iiuid -tight connections there oetvveen.

7. ln an apparatus for converting oils of higher boiling points into oils of lower boiling points, the. combination of a tubular decomposing retort capable of being operated under a pressure or several atmospheres, a pump for pumping oih into said. retort, against superatrnospheric pressure therein; a preliminary condenser, means "for maintaining in said retort, a pressure materially above the pressure in said condenser, means for passing the gases and vapors from said retort to and through said preliminary conlenser, means for compressing the gases and vapors leavinp" the said preliminary eondenser, and means for further cooling the sai gases and vapors.
