the backward stroke of the piston. Preferably on the other side of the cylinder are 10 ,valves 12, which close exhaust-ports 13 and ll. These valves arepreferably provided with sleeves heads, and collars, substantially iike those on the valves 5. A spring 2d'is interposed between .the nut 17 andthe collar :5 19 of these valves 12, which is comparatively strong, so 'as to keep said valves firmly upon their seats excepting when the cam 21 strikes the lower end'of the valve-stems 18 and raises. The.

them elf their seats at the proper time. so cylinder-head 22 fits over the top of the cylinder-casing and is preferably provided with a recess 23 and extensions thereof 24 and 25, which'fit-ov'er the valves 5 and 12, respectively, and in this way make'connection be- :5 tween the vaporizing-passages 4 and said cyl- 'ildel and between said cylinderand exhaustports 13, respectively.

It will be seen that in this embodiment of my invention the vaporizeris applied directly to the face of the cylinderand the fluid to be vaporized is discharged into a passage within the cylinder-casing and near the combustionchamber, which is on this account kept extremely hot. This insures a quickvaporizing of the fluid, which when one oi the valves 5 is raised passes out into the cylinder or 'combustionchambers'1 2. .It is a' common detect in these engines for the parts immediately surrounding the points where the vap- 0 oriziug takes place to becomechilled on account of the loss of heat resulting therefrom, and consequently such vaporization is retarded. In this embodiment of my invention, however, this is almost entirely prevented, 3 for the atomizer discharges directly into this hot vaporizing-passage and has only to pass the valve 5 to enter the combustion-chamber. This almost entirely prevents any cooling of the vapor.

The overflow construction keeps the oil at a certain level, so that it is supplied to the atomizer ata uniform rate. 4 I I is a valve screw-threaded into the casing and having an actuating knurled head 1", a shoulder R, and a conical projection S to regulate the flow of hold to be vaporized, as shown.

The operationot this embodiment is as follows: ,Oil passes up through the'tnbe L and rises to the level of the atomizer and is kept at this level by the overflow-pipe M. When the piston moves backward, (in Figs. 7 and 8 downwarth) air is drawnin through the opening Ii into the passage 4 and draws in the form of spray a certain amount ofoil out of the atomizer. This amount is regulated by the position of the screw 1, carrying the valve 'one of my atomizers is necessary, and it will S. As-soon as the piston starts to move backward a partial vacuum is produced ahead of itand the inrush of air resulting therefrom 7o raises the valve 5 off its seat. As soon as the spray of fluid enters the hot passage 41t1s converted into vapor, and as the valve 5 is now off its seat it rushes out into the combustion-chamber or cylinder ready to be compressed on the return stroke of the piston and ignited in the usual or any suitable manner.

, Of course it will be evident that a one-cylinder engine may be used and that then only 8 0 be evident that mauy'moditications of this construction may be made without departing from the spirit of my invention.

It will be observed by my invent-ion no r;

'nlation of the air-supply is necessary, as the piston draws in the requisite amount, and the only regulation necessary to be used in this embodiment is the regulation of the oil-supply, which can be accomplished by means of the screw I. In this way the amount of vapor 9o supplied may be regulated by the oil-supply regulation alone.

What I claim is- 1. In a vaporengine in combinationa cylinder-casing inclosing two cylinders, a pair of vapor-passages also inclosed by said casing and located near one end of the same and each connected with one of said cylinders'said passages opening through one side of said casing close together, a vaporizer, applied directly to said casing over and covering said openings from said vapor-passages, having a pair of atom izing-nozzles, a fluid-supply connected therewith, each of said nozzles hating a plurality of atomizin'g-points and extending into said casing and directed toward said vaporpassages, and an air-passage past each of said nozzles and connected with said vapor-passages to spray said fluid directly into said vapor-passages.

2.

and an air-supply passage past said nozzles and connected with said vapor-passages to spray said liuid directly into said vapor-passages, and a valve between said fluid chamher and nozzle to regulate the flow of lluid therefrom.

3. In a vapor-engine in combination, :1. cylnozzle connected to inders, a vapor-passage located through the side of inder, a casing inclosing said cylinder, a, vaporpassage located entirely within and at one end of said casing, said passage connected with said cylinder and opening 'through the side of said casing, an inlet-valve in said passage, a vaporizer attached directly to said casing and covering said passage, saidvvaporizer having a liquid-fuel compartment or tank, provided with a liquid-fuel supply, and an air-passage provided with an air-supply and connected tosaid,vapor-passage,an atomizingsaid fuel-tank extending through said air-passage into said casing and directed along said vapor-passage, substantially as described. r

4. In a vapor-engine in combination, a plurality of cylinders, acasing inclosing said'cylentirely within and atone end of said casing said passage connected with said said casing, an upright partition between said passages, an inletvalve' in each passage, a vaporizer attached directlytc said casing and over said passages, a liquid compartment or tank in said vaporizerand'a liquid-fuel supply therefor, an aircylinders and opening passage and an air-supply therefor, said airsupply being connected to said vapor-passages, a plurality of atomizing-nozzles connected to said fuel -tank and extending throughsaid air-passage into said casing and directed along said vapor-passages.

5 In a vapor engine in combination, a casing nclosing a cylinder, a vapor-passage located entirely within and at one end of said casing, said passage connected with said cylinder and opening through the side of said casing, an inlet-valve between said passage and cylinder, a vaporizer attached directlyto said casing and covering said passage,'said vaporizer having a liquid-fuel supply and an atomizing-nozzlc connected to said fuel-supply and directed through said air-passage and into said casing to project said liquid fuel directly into said vapor-passage.
