VAPORIZING Ann/IGNITION DEVICE.

srncmlca'non' {ma M of Letters mm No. 532,097, dated January 8, 1 s95.

' Application al a-na 24.1894. Serial No.512,308. (mam To all whom it may concern: I

is it known that I, JOSEPH ROBISON, a citizen of the United States, residing at G reenbush, Rensselaer' county, New'York, have invented certain new and useful Improvements in vaporizing and Ignition Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanymg drawings, and to the figures of reference marked thereon, which form a part of this specification.

The object of my invention is to provide a new and improved vaporizing and ignition tube for oil or vapor engines.

In the drawings, Figure 1 shows a side elevation of a portion or the cylinder of a gas, oil or vapor engine with a similar view of my ignition and vaporizing device and the heatingjacket therefor injverticalsection; Fig. 2,

an enlarged longitudinal sectional view of my vaporizing and ignition device; Fig. 3, an end view of the ignition'tube taken on line b. b.' of Fig. 2, and Fig. 4, a cross sectional view thereof taken on line a. a. of that figure.

theair being taken in through the opening 3'.

4 shows the body of my vaporizing and ignition device which consists of any strong metal and is hollow and preferably set in connection with the cylinder 1 in a slanting position. The device or tube 4-has a valve chamber 4' and to the valve chamber is preferably attached an ordinary valve 5 and is put in connection with an oil supply 7 by means of a pipe 8 or in any other manner desired.

The tank 7 shows the-oil as being. fed by gravity, but the tank 7 shown in dotted lines, shows the oil as being arranged to be fed by suction .to the ignition and vaporizing tube.

This tube 4 may be attached to the cylinder by an anglebush 4" as shown, or it may be flanged and bolted to thecylindcr 1 or affixed thereto in=-any well known manner. Inside .the tube 4.is a copper stem 18 which is fastened in 'an annular nut 19 and the nut screwed into the largeend of the tube 4, said nut- 19 having a portion of its sides removed as seen at 4". so that there may be ingress and egress past the nut into and out of the tube 4, and in theend of the copper stem I form a slot 20-to take a screw driver that the stem 18 may be easily 'put in and taken from the tube 4. The end of the nut 19 and copper stem 18 and the openings 4' will be clearly seen in Fig. 3 which is a view taken of Fig. 2 on line b. b.

In the valve chamber 4' is a valve 17 having a triangular stem 14 ending in a circular threaded end to receive the nut 15 and about the circular threaded end isthe coiled spring .16 which acts to'keep valve 1? closed, its

pressure being but suiiicient to close it when there is no vacuum in the chamber 4. A cross section of the chamber and triangular portion of the stem will be clearly seen in Fig. 4, the triangular portion allowing of the oil to flow down to the'valve when it is closed and beyond it when open. Referring to Fig. 1 my vaporizing and ignition tube will be seen inclosed in a heating jacket 9 which may be made of sheet iron or other desired material and I have. shown its interior surfaces covered with a nonconductor of heat 9, preferably consisting of asbestos and under the jackct is a source of heat 10, preferably a vapor burner. 7

At 14 will be seen the ordinary exhaust I valve used with many gas engines and at 11 the opening to the water jacket of the cylinder, the pistongtnd its rod being shown in dotted lines at 12 and 13.

The operation is as follows: The engine will be considered to be working on the Otto c ole. Valve 6 being open to allow a flow of oil through valve 5 and to valve 17, the piston 12 will on its down'or suction stroke produce}; vacuum in the top of the cylinder which will create a vacuum also in thetube 4, and the vacuum will causeithe valve 17 to open and allow a quantity-of oil to enter tube 4 and also cause air valve ,3 to open and allow a v and thereby mixed with the air taken in charge of air to enter the cylinder 1. As the oil. enters tube 4 that tube will-be heated to redness by the source of heat at and the oil will be vaporized and itsvolume being thus greatly increased it will force itself through the. tube 4 and openings 4f" into the cylinder through valve 3.v Oh the upstroke or .com-' pressionfstroko of the piston, the mixture of oil vapor and air will be forced in part out of the cylinder and into the red hot tube 4 where it will be ignited and cause the necessary explosion. of the mixture required to keep the engine in motion. Atthe proper moment'the exhaust valve will open and the exhausted products of combustionwill escape therefrom as in other gas engines a particular description thereof beingdeemed unnecessary as I.

claimnothing new ornovel in this pecifica- .tion regarding the exhaust valve.

I have made. use of the'stem 18 in order to reduce the area of. the opening, in the tube 4 and also as a retainer of the heat in that tube, it assisting to vaporize the oil. \Vhen the oil tank is located below the month of the tube 4, as seen in the dotted lines in Fig. 1, the suction produced by the vacuumin the tube will suck up or causeto rise into that. tube sulii cient oil for'cach chargeto the tube. It wil be seen, therefore, that my device is eaten lated more'especially for the purpose of utilizing oil with vapor engines, the oillfind bestadapted for use being 150 or proof kerosene oil, and as that oil is perfectly safe to handle under ordinary temperatures up to 150 Fahrenheit there is no danger of the supply tank giving off explosive vapors as there is when gasolene or the lighter oils are used.

With my improvement in vaporizing and igniting the charge, it becomes perfectly practical for engines using'my improvementto be used every where without danger from ex plosion and where it is impossible to obtain manufactured or natural gas and where gas-' oline and the lighter oils wonldbe unsafe besides reducing insurance in such buildings where-my improvement is used.

I am not aware that any kind of adevice has ever been used with an oil or vapor engine keeping the cylinder as cool as possible.

water jacket used with cylinder 1 is the same taken directly into the cylinder 1 as cool as the surrounding atmosphere, thus tending to partly cool the cylinder thus assisting. the water in the water jacket about th'e cylinder in. The

as is usually used with all gasengines and a detailed description is deemed unnecessary.

Having described my invention so that those skilled in the art to which it appertains may make and use the same, what I claim, and desire to seizure by Letters Patent, is-' 1. In combination with an oil or vapor engine, an oil conduit arranged to'dis'charge into the engine cylinder and having an automatic intake valve and an oil reservoir connected with said valve, and a jacket for said conduit and a source of heat arranged to heat the 'conduit to a degree suflicient to both vaporize the oil and also ignite the vapor when mixed with air, said conduit having an internally located body arranged to absorb a portion ofthe heat, substantially as described.

2. -A vaporizing and ignition devicefor oil f and vapor engines consisting of a tube affixed to the engine cylinder and discharging into the same, and arranged so that oil entered therein will by gravity flow ,down the tube,',

and an autoinatic'- .intake valve arranged to ,open on the suction stroke of the piston, and

an oil tank communicating with said valve and arranged to deliver its oil thereto by gravity and having a check valve arranged to govern the flow of oil from the tank to the intake valve, and a source of heat arranged to heat the tube to a degree sufficient to vaporize the oil and ignite the. same when mixed with air and having a jacket for the tube, substantially as described.

- 3. A vaporizing and. ignition device for oil and vapor engines consisting of a tube and a metal stem therein and ports ieadingfrom the tube into the gas engine cylinder and a. valve chamber attached to'the stem and containing an automatic acting valve arranged to open and olo'seon the movement of the engine piston and a check valve arranged to'limit the supply of oil to said automatic valve and an oil supply discharging into said valve and a source of heat arranged to heat the tube to a degree sufiicient to both vaporize the oil and ignite the vapor when mixed with air and a jacket for the tube, substantially as described.

In testimony whereof I affix iny signaturein presence of two witnesses.

- JOSEPH ROBISON.
