GASOLENE OR VAPOR ENGINE.

SPECIFICATION forming part of Letters Patent No. 570,500, dated November` 3, 1896.

Application led November 1,1895. Serial No. 567,600, (No model.)

To @ZZ whom, it may concern:

Be it known that I, ENOCH PROUTY, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gasolene or Vapor Engines, of which the following is a specification.

My invention relates to gasolene or vapor engines.

The object of my invention is to produce a gasolene or hydrocarbon engine of a simple, eicient, and durable construction, that will operate economically, utilizing to the best advantage thc power generated by the explosion of the compressed air and vapor mixture, and at the same time securing the proper admixture of air with the vapor, so as to produce the best results, and having a sensitive and effective means for governing and controlling the speed of the engine and also the feed of the liquid hydrocarbon to the engine, according to 'the varying requirements of the load or mechanism driven by the engine.

My invention consists in the novel devices and novel combinations of parts and devices herein shown and described, and speciiied in the claims.

In the accompanying drawings, forming a part of this specification, and in which similar letters of reference indicate like parts throughout the several views, Figure l is a side elevation of a hydrocarbon-engine embodyingmyinvention. Fig. 2is a front view. Fig. 3 is a section on the line 3 3 of Fig. 2. Fig. et is a detail elevation of the governor. Fig. 5 is a section on the line 5 5 of Fig. 4. Figs. 6 and 7 are det-ail elevations of the cam which is moved or controlled by the governor by which the feed-pump is operated, showing the sliding cam in different positions; and Fig, S is a detail plan or face view of this cam. Fig. 9 is a detail sectional view of the vaporizing-chamber and showing the positive cut-oit or gate in the gasolene or hydrocarbon feed passage or pipe at ornear the discharge orifice or nozzle. Fig. l0 is a detail sectional view of the feed-pump. Fig. ll is a detailsectional view of the powdercharge starting device Jfor the engine. Fig.

l2 is a detail sectional view of the stationary Fig. 13

contact-piece of the electric igniter.

is a detail sectional view of the muffler device through which the exhaust is finally discharged from the engine and by which the noise of the exhaust discharge is diminished. Fig. lt is a detail sectional view of the piston, and Fig. l5 is a detail view ot the friction-clutch mechanism on the driving-shaft of the engine.

In the drawings, A represents the frame of the engine; B, its piston; C, its cylinder; D, the driving shaft, having` a crank D', connected by a pitman-rod D2 to the piston B, and E E are the ily-wheels, one being arranged,preferably,on each side of the cylinder.

The piston B is provided with the customary metallic packing-rings b, and with annular channels or grooves b for receiving an oil or lubricant, and with a series of solid, compressed graphite plugs or disks b2, rigidly and firmly inserted in suitable cavities bored in the piston to receive such graphite lubrieating-plugs. are preferably arranged in two or more annular rows b4 b4, extending around the cylinder.

The cylinder C is furnished with a water jacket or chamber C to prevent the cylinder from overheating. F is the movable contactpiece, and F the stationary contact-piece, of the electricI igniter. The stationary contactpiece F consists of a metal pin connected with the electric circuit F2, and insulated from the engine by a tubular bushing F3 of lireclay or other insulating material, surrounded with an asbestos or other packing F4 where it enters the port of the engine, and which is held in place by a metallic cap F5, rigidly sccured to the engine by bolts FG. The movable contact-piece F of the electric igniter consists of a sliding baror rod which is moved into contact with the contact-piece F by means of the spring f, and separated therefrom by a positive-acting mechanism, preferably a cam d on the cam-shaft D3, so that the two electrical connections F F may be thus brought yieldingly into connection with each other with the fixed and definite degree of pressure due to the tension of the spring and then positively separated yby the operation of the cam or otherlike positively-acting mechanism, thus insuring with certainty the proper making and breaking of the circuit to The series of graphite plugs IOO produce the requisite spark to cause the ignition of the gas. As the two contact-pieces are brought together by the spring the making of a perfect electrical connection between them on the one hand or the prevention of jamming or injuring the contact-pieces on the other hand does not depend upon the adjustment of the cam or positive mechanism for moving the movable contact-piece.

G is the valve-chamber, G the inlet-valve, and G2 the outlet or exhaust valve. The valves G' G2 are normally held closed by springs g g', acting against the valve-stems The spring g', which holds the exhaustvalve G2 closed, is made sufficiently stronger than the spring g, that holds the inlet-valve G closed to cause the inlet-valve only to be opened by the suction of the cylinder when the piston B is making its outward stroke, so that the air and vapor can only be drawn into the cylinder through the inlet. The exhaustvalve G2 is opened and held open to permit the discharge of the exhaust from the cylinder C by means of a cam d on the cam-shaft D3 of the engine, and which engages an antifriction-roller g4 on the stem g3 of the valve G2.` The springs g g' are mounted in closed guides or caps g5 Q6, attached to the valve-chamber shell, and which also form closed bearings for the valve-stems g2 g3 to reciprocate in. Although these guides or caps which contain the springs are closed, the springs are not injuriously affected by the heat, as the valvestems close the communication with the valvechamber approximately tight.

H is the vaporizing-chamber, connected directly with the valve-chamber, and H is the gasolene or other liquid hydrocarbon feed passage or pipe, the same terminating in a nozzle or feed-orifice 7L inside the vaporizingchamber H. This nozzle or feed-orifice h projects, preferably, upward or toward the inletvalve, and is preferably of an annular form, so that the liquid will be separated into a thin annular sheet as it is discharged from the same. The feed-passage, or the portion thereof connected directly with the annular feed-orifice 7L, is preferably formed in a cylindrical plug h by forming a central bore h2 through the same, and a radial bore h3 communicating with the central bore and with the annular orifice 7L, so that the periphery of the plug may form the inner wall of the annular orifice. The outer wall of the annular orifice is preferably formed by a sleeve 724, surrounding thev plug 71.

K is the positive cut-off or gate for closing the feed-passage H at or near its discharge orifice or nozzle. This positive cut-off or gate may be of any desired construction suitablefor performing this function. It however preferably consists of a sliding pin or piston reciprocating in the central bore h2 of the plug h and operating to close the feed-passage at the radial bore h2. It is closed and held normally closed by a spring K. It is opened by the 'stroke of the feed-pump M through the pressure of the hydrocarbon or liquid against the gate or cut-off overcoming the pressure of the spring K. As the feedpassage is thus positively closed by a gate or valve near the feed-orifice the instant the required quantity of liquid is forced into the Vaporizing-chamber by the feed-pump, the forcible suction of the air through the vaporizing-chamber is thus prevented when passing the feed-orifice from drawing or sucking the gasolene or hydrocarbon from the feedpassage and thus occasioning irregularities in the quantity fed at each successive time or stroke.

The feed-pump M, which operates to inject the gasolene or hydrocarbon in fixed and regular charges or quantities, as required, into the vaporizing-chamber, communicates with the reservoir containing the liquid or with the pipe M leading thereto, and also with the feed pipe or passage H', leading to the vaporizing-chamber I-I. This pump preferably consists of a cylinder in which iits a piston M2, furnished with an adj Listing-screw m to regulate the stroke of the piston and thus the quantity of liquid fed at each movement. The piston of the pump is operated in one direction by a spring M3 and in the other direction by a cam d2 on the cam-shaft D3, which engages an antifriction-roller m on a guide-rod m2, connected with the piston of the pump by an arm m3.

N is the governor, the saine comprising, preferably, a disk or wheel N and two diametrically opposite weights N2 N2 on quadrant-arms N3N3, which are pivoted at n to the disk and which are connected to the opposite arms of an oscillating lever N4 on the calnshaft D3 by means of pivoted links N5 N5. The weights or Weighted arms are pulled toward each other by springs NG N6 and are forced apart by centrifugal action as the disk revolves. Connected to the weights are a pair of slides N7 N 7, that engage the tapering end d4 of the sleeve clicarrying the pumpoperating cam cl2. to reciprocate on the cam-shaft D3, so as to throw the cam cl2 into and out of engagement IIO The sleeve d? is adapted with the roller m' on the pump-actuating l slide. The roller m and the cam cl2 are both made cone-shaped or Haring, so that a very slight sliding movement imparted to the sleeve d5 by the governor-operated slides N7 N7 will sufce to move the sharp or tapering edges of the cam d2 and roller m into engagement or past each other, and then the further revolution of the cam, by reason of its tapering or inclined face, will itself operate to further reciprocate the sleeve d5 and thus bring the cam d2 into full and proper engagement with the roller m. A very slight movement of the governor will therefore serve to control the pump and the consequent feed of hydrocarbon to the engine, so that I am thus enabled to keep the engine under perfect control. A spring N8 serves to move the reciprocating sleeve d5 in the opposite direction to that in which it is moved by the governor-actuated slides N7 N7.

The sound-muffler P consists, essentially, of a chamber preferably several times the capacity of the cylinder, into which the exhaust is led through a pipe P' from the exhaustvalve, and which is furnished with an interwoven wood-slat and wire-screen bottom or side, there being preferably several thicknesses of wire screen or netting interwoven or interlaced with the wood slats, and through which the exhaust passes, and by which the force of the exhaust-blast is broken, scattered, or dissipated. The muiiier-chamber P is preferably of wood.

The powder-discharge starting device comprises a metallic thimble, charger, or cartridge R, having a slot r at its upper side to permit ignition of the powder therein, in connection with an externally-screw-threaded socket or receiver R for the cartridge, which is securely fixed to the cylinder by threaded bolts or screws r at the opening R2 in the cylinder, and an internally-screw-threaded cap R3, which serves to hold the cartridge R securely in place while being fired. The cartridge-receiver R and the cap R3 are furnished each with a touch-hole opening r2, registering with the slot r, through which the powder in the cartridge may be conveniently ignited by a match in starting the engine.

The driving-shaft D of the engine is provided with a loose gear or pulley S thereon, which is adapted to be gradually clutched to the driving-shaft, so as to revolve therewith, by means of two friction-disks S/ S2, one on each side of the gear or pulley S, both of the disks being keyed so as to rotate with the shaft, and one or both of them, preferably one, being so keyed to the shaft that it may slide thereon while rotating therewith. These two disks S S2 have slightly-beveled or coneshaped outer faces s S, and they are forced together, so as to frictionally clamp the gear or pulley S between them, by means of a rotatable spool or wheel S3, having two bevelfaced flanges or collars s s2, adapted to engage the bevel-faces s s of the disks S S2. The flanged wheel or spool S3 is moved into and out of engagement with the disks S S2 by means of a clutch-lever S4, connected by a pivoted rod or link S5 with the spool S3 or its hanger S6. I preferably employ two spools S3, the same being connected together by the common hanger-bar S6, one end of the hangerbar being connected by a pivoted arm or link S7 with the frame and the other end of the hanger-bar being connected by the link S5 with the clutch-lever Si. The clu'tch-leverS4 is provided with a pawl SS, engaging a ratchet S9, the pawl being operated by a pawl-lever connected by a link with the pawl. As one of the disks S S2 is on eachvside of the gear or pulley S, it will be observed that though the friction between the disks and the pulley is produced by a pressure in the direction of the axis of the driving-shaft this'pressure on the shaft is nevertheless equally balanced. There is therefore by this arrangement no side pressure or end thrust on the drivingshaft or crank-shaft of the engine tending to interfere with the proper operation of the piston in its cylinder or to produce friction or wear between these parts. As this clutch operates gradually and by friction to transmit the power of the engine to the gear or pulley S, the gear and pulley or machinery or mechanism to which it is connected may be rotated at any speed desired, whatever the speed of the engine, and any amount of power desired transmitted, by simply moving the clutch-lever.

T is a tank or reservoir for holding the Water for cooling or keeping down the temperature of the 'cylinder C by circulation through the water-jacket C' thereof. This tank has an open top and is located directly over the engine-cylinder, and communicates with the top of the water-jacket thereof by a number of straight direct passages or pipes T', extending directly through the bottom ofthe tank, so that whatever steam may be generated in the water-jacket may escape directly into and through the body of water in the tank, and thus prevent any pressure or connement of the steam in the water-jacket or in the pipes or passages leading from the water-jacket to the tank. A pipe T2 leads from the lower end of the tank to the lower portion of the waterjacket, thus bringing the cooler water from the bottom of the tank directly to the lower portion of the water-jacket, while the hotter or heated water at the upper portion of the water-jacket C is continuously discharged directly into the open pan or tank T, from which the vapor can freely escape and thus permit the water to cool. By this means the water in the tank is prevented from being overheated, and at the same time a comparatively small tank or reservoir of Water is rendered fully adequate to keep down the temperature of the cylinder, as required.

The cam-shaft Dis driven at half the speed of the crank or driving shaft D by gears U and U.
