GAS, olt, ORVAPOR ENGINE.

SPECIFICATION forming part of Letters Patent No. 532.098, dated January 8,1 895.

. Application filed May 24, 1894. Serial No. 512,309. (No model.)

To all whom it'may concern:

Be it known that I, JOSEPH ROBISON, a citizen of'the United States, residing atGreenbush, Rensselaer county, New York, have in- 5 vented certain new and useful Improvements in Gas, Oil, or VaporEngines; and I do hereby declare thecfollowing to be a full, clear, and exact description of the invention, such as avill enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawing,and to the figures of reference marked thereon, whichforms a part of this specification.

The object of my invention is to provide a new and improved gas, oil or vapor engine.

Inthe drawing the figure shows a side elevation of a vertical gas, oil or vapor engine with my vaporizing andignition tube and its heating jacket, my gas and air mixer and my exhaust valve shown in vertical section.

In the drawing the numeral 1 shows the engine cylinder; 2, the fly-wheel; 3, the belt wheel; 4 and 4, gear wheels in the relation of two to one; 5, a cam on the journal of the gear 4, by which the exhaust valve 12 is operated, said valve 12' having its stem pivoted to the valve by a balland socket joint 12 and a sharp edged seat for the valve 12", the valve stem having a spring 8 bearing against a nut and acting to close the valve, said nu't having a hollow or tubular extension in which the rod 8 loosely plays up and down, said rod 8 ha'v ing to force that valve open in order to allow an inflow of air through opening 26 into the cylinder. On cam 6 is a crescent 7 which operates the rod 9 which passes through the steadying sleeve 9' and the bracket and at its outer endis yoked to the pivoted lever 16 which lever is also pivoted to the upright arm 17 which acts to open the oil valve 21 against i the pressure of the spring about itsstem.

having a copper or other metallic stem end attached to the valve stem and.operat-' 19 shows my vaporizing and ignition tuber passing through or into it and connected to the outer cndof the vaporizer and igniter is the valvefll and its casing. Aboutjthe ignition' and. vaporizing tube 19 is a heating jacket'22 and underthejacketis a source of heat 18 preferably a vapor or oil burner and preferably suppliedfwith fuel through pipe 18 frompipe 2i which pipe 2% leads to a tank of oil 23. 1

In the cylinderwili be seen a perforated annular sieve 14 which is preferably mide of strong material like boiler plate and finely perforated and attached preferably to the head of the cylinder 1 inany well known manner as by bolting it. fast thereto, the diameter of the annular sieve being preferably somewhat lessthan the inside (liameterof the cylinder so as to leave a slight space be tween the sides of the sieve and the inside surface of the cylinder, and hanging down into the cylinder" suiliciently to receive the charge of gas or vapo'r from the ignition and vaporizing tube 19. A complete understanding of the engine will be derived from the following explanation of its operation.

The tank is charged with oil, preferably 150 proof or test kerosene. The oil is then lighted in the burner 18 and allowed to burn until tube 19 is heated .to redness. Fly wheelZ-is now turned when the gears -i and 4 willset in motion the came 5, 6, and the crescent As the crown of the earn 6 rises to its highest point or to any point predetermined, the arm 10 rises forcing the free end of lever l0-to press down the air valve 25, the piston of the enginebeing on its down or suction stroke. Crescent? has also operated to raise arm 9 and force lever 16 upward which forces valve 21 off its seat allowing a char-goof oil from tank 23 to enter through that valve and pass into the ignition and vaporizing tube 19 where the oil is vaporized by coming in contact with the heated surfaces of the pulse and with heater. stem 20 and this vapor passes through openings lfiabout the base of stem 20 into the engine cylinder and through the sieve 14. As the piston rises on its compression siliilit, the oil vapor or gas and the air that have been sucked into the cylinder by the suetiw, stroke of the piston, are now compressed 1n:

' mixed and a part of the mixed oil-vapor or gas and air is forced back into the ignition.-

tube 19 and. ignited which causes the neces' sary explosion in tbe-engln'e'eyltnder; The piston now descends again and ,atwa'r- Joint which is'five sixths of "its downward stroke "the cam o-begins to operate so as to raise the exhaust valve.12 and the products of combustion are discharged through this valve as indicated by the'small arrow.-

,The engine will be understood as operating on What is universally known as the Otto cycle. As the piston rises on its compression stroke valves 21 and 25 are closed.

The valve 12', the ignition and vaporizing tube 19, the sieve 14 and the method of op-- erating the valves 21, 12 and 25 bypositive movement are the new and novel features in thisengine shown and described. 7

The valve 12' has a ballantl socket connec-.

tion 12--with-its*istem and a sharp or knifeedged seat 12" in order th'at th'e'valve 12' may be seatedbythe downwardpnll.of'the stem and have an even bearing on its seat nrider all circumstances whether sedi n'ent collects on the under side of the valve or ,noLor whether any foreign substance rests on the knife edged seat or not, the knife edged seatcutting throngh any substance that will'ordinarily present itself to it. The sieve lat acts as a strainer to the oil vapor and air thilt'envz tors-the cylinder on the suction strekebfthe piston and still more so on the compression" stroke, as during the compression stroke the mixed gas and air is forced more or less'through the hneperforations and thoroughlymixed,;' that portion ,of the mixture re'entering'thei ignition and vaporizingt'ube being'compelled' to pass through the sieve and is thoroughly mixed ready for ignition.
