SPECIFICATION forming part of Letters Patent No. 335,629, dated February 9, 18B.

Application filed September 9, 18.85. Serial No.176,585. (No model.)

To all whom it may concern:

. Be it known that I, ALEXANDER KIRK RIDER, of Valden, in the county ofOrange and State of New York, have invented certain new and useful Improvements in HydrocarbouVapor Engines and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hydrocarbon-vapor engines, or internal-combustion engines, in which petroleum or other liquid hydrocarbon is used as the fuel and motive power.

The objects of the invention are to provide an engine of such construction that the hydrocarbon oil used therein shall be converted into and burned in the form of vapor or steam,

instead of in the form of a liquid spray, as has been the ordinary custom heretofore; further, to provide means for thoroughly vaporizing the hydrocarbon oil within the engine, and intimately mixing and commingling therewith a predetermined proportion of I air prior to the ignition of the charge further, to provide simple and efficient means for igniting the eX- plosive mixture of hydrocarbon vapor and air at proper intervals of time to operate the engine; further, to produce an engine embodying certain features of construction, and of such availability in use as will permit of its employment under conditions andcircum- 'stances which would preclude the use of the Y construction and combinations of parts, as will hereinafter be described, and pointed out in the claims.

ln the accompanying drawings, Figure l is a vertical section of one form of engine pro vided with my improvement, some of the parts of the engine, such as the inlet and exhaust valves, valve-gearing, governor, &c., not being shown, in order to simplify the description. Fig. 2 is a horizontal section. liig. 3 is an enlarged detached view of the ignlter, and Figs. 4 and 5 are modifications of the oil?. inlet pipes, and Fig. 6 is a detached view of the oil-regulating governor.

A represents the cylinder provided with a water-jacket, B, the piston; C C, the cranks; D, lthe connecting-rod, and E` the frame or bed-plate. All these parts may be of any approved construction or type.

I have represented the improvement as applied to an engine of the alternate typethat is to say, an engine making one effectlve power stroke for each alternate revolution of the shaft. At the'outer end of the cylinder is located the combustion-chamber F, which is simply an extension of the main cyllnder, forming a chamber in which an explosive mixture is ignited. Within the combustion chamber is placed the vaporizer H, which may consist of a circular block of pumice-stone or other porous material, preferably hollowed out or made concave on its upper surface and fitted into a recess in the lower portion of the combustion-chamber. That portion of thecylinder adjacent to the vaporizer is not provided with a water-jacket, in order that the heat stored in the cylinder or that portion thereof near the vaporizer may be imparted to the latter and retain it in a heated state. It is not absolutely necessary that the vaporizer shall be inserted within a recess in the cylinder, as shown, as it may be secured within the combustionchamber at any distance above its lower portion or wall, in which case it might be furnished with a thin ring or hoop having' projecting ears for fastening it in position.

l? is an oil-pump, the cylinder of which has connected therewith the induction-pipe T and delivery-pipe L, the latter extending through the cylinder and terminating over the Vaporizer H. A connecting-rod, n, connects the pump rod or plunger with a wrist-pin on the gear m, which meshes with a gear on the main shaft, said gear in the type of engine shown` making one revolution to two revolutions of the main shaft, while in engines making an effective power stroke at each revolution the connections for transmitting motion to the pump would of course be connected with and Worked from the main shaft. At each effective stroke the pump operates to deliver a small IOO quantity of oil onto the vaporizer. On lthe induction-pipe "I of the oil-pump is located an oil-supply-regulating cock orvalve, M, by means of which the supply o`f oil from the oilreservoir M3 to the pump may be regulated. To the valve M is attached an arm, z, the free end of which is bifurcat'ed and connected with the sleeve z of the governor Z, which latter is operated by means of a belt engaging the pulley z2 and extending around ja pulley on the engine-shaft. By means of the governor the position of the valve is automatically controlled so as to regulate the speed of the engine by varying the supply of oil delivered to the I combustion-chamber. On the induction-pipe l is also placed a tight or pressure oil-cup, M2, to contain benzine or other light hydrocarbon which is used to start the engine before 'the vaporizer has been sufficiently heated to vaporize the heavier vhydrocarbon supplied to the pump for actuating the engine.

l R represents vanair-inlet, preferably located at the side of the cylinder and so situated that 'the air entering the cylinder will spread over the vaporizer and produce a very complete and intimate mixture of the air and hydrocarbon vapor. S is an exhaust 'opening located at the upper part of the combustionchamber and over the vaporizer, which is the preferable position for the exhaust, as itinsures a rapid and effectual clearance of the products of combustion. Both the air-inl'etR and the exhaust-passage S Iare provided with valves having suitable connections for "their automatic operation at proper intervals of time, although the valves and their operating mechanism are not shown, Aas many different forms of construction and arrangement of lsuch parts might be used, and hence I do not coniine myselfto any particular means for operating the valves.

I is the igniter, and consists of a platinum tube, i, secured to the cylinder-head, the tube having inclosed therein a platinum wire, I', which is constructed and adapted kto be reciprocated within the tube 'so as vto be projected into the combustion-chamber to ignite the explosive mixture or chargecontained therein and then to be retracted into the tube again for reheating and retained therein out of the way until the proper time for the ignition of the next succeeding charge. The tube ,and wire are maintained' above the igniting temperatureby a Bunsen burner, K, or `any other source of heat that may be found 4adapted for the purpose. YWire Iis reciprocated at proper intervals of time by suitable connections on the engine, although no special mechanism for this purpose is shown, as it is obvious that many contrivances might be devised vfor imparting the proper vmotion to the ignitingwire.

.Instead of supplying the oil through a pipe, Ii,'as arranged in Figs. l and 2, the pipe may project upwardly through the vaporizer, as represented in Fig. 54, and extend above the same and 'terminate in a perforated head, j,

through which the oil is delivered upon the surface-of the vaporizer. In Fig. 5 is illustrated 'another arrangement of oilsupply pipe, the latter extending upwardly through the vaporizer and terminating fiush with the upper surface thereof or slightly below the surface.

Instead of constructing the vaporizer of pumice-stone, it may be made of metal with a roughened or serrated surface or with ribs or projections, orof thin metal plates, or of metal wire, platinum sponge, iron chips confined in. a suitable cup, or, in fact, any material or substance affording the proper amount of heating and evaporating surface to properly and rapidly vaporize the oil that may be used.

The igniter-tube may be made of porcelain or other refractory material, instead of being made of platinum. Instead of' employing a platinum wireto ignite the charge, a small portion of the explosive charge can be forced through the heated tube, and thus ignite the charge i-n the combustion-chamber.

Having described the construction and relative arrangement of' the'different parts of my improvement, I will now briefly describe its operation.

The Bunsen burner K is first lighted, and the platinum tube and wire heated to the iguiting-temperature, care being taken that the wire is Well within the tube. Next the Oilcup, containing benzine and communicating with the inductionpipe, is opened to allow a very small quantity of benzine to flow into the oil-pump, and then the oil-cup is again closed. The `engine is then turned by hand half a revolution, which will be sufficient to operate the pump and force a drop or two of benzine onto the vaporizer, which will at once by vaporization fill the combustion-chamber'with an explosive mixture: As the stroke of the pump is closely followed by the introduction of the heated platinumwire of theigniter, the charge will be red and the engine regularly started. The small quantity of benzine in the oil-supply pipe will keep the engine going for a few .revolutions and cause the vaporizer to become sufficiently heated to vaporize the heavy oil used for operating the engine. operation of the engine the oil-pump delivers a minute quantity of oil onto the vaporizer at each leffective stroke of the engine. The vaporizer has, by the continued and successive explosions of the charges in the engine, a sufficient amount of heat stored therein to instantly vaporize the oil as it is discharged thereon by the pump. This quickly-formed vapor in the engine cylinder encounters the incoming In the regular- IOO IIO

charge of fresh air, and becomes instantly and l intimately mixed therewith, the law of' the rapid diffusion of vapor through air favoring the operation greatly. This charge is then exploded by the igniter, as has been explained.

Having described one embodiment of my invention and its operation, it will be evident that many changes might be made in the construction and relative arrangement of the parts Without departing from the spirit of my invention, and hence Iwould haveit understood that I do not restrict myself to the particular construction and arrangement of the parts shown and described.
