GEORGE F. DYER, OF BEVERLY, MASSACHUSETTS.

VAPORIZER FOR EXPLOSiVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 680,572, dated August 13, 1901.

Application filed February 13, 1901. Serial No. 47,090. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F. DYER, a citizen of the United States, residing at Beverly,

in the county of Essex and State of Massa- 7 ing the air-valves and hydrocarbon-supply valve in elevation. Fig. 3 represents a bottom plan view of the invention, showing a portion of the head of the adjusting-sleeve for the air-valve seat broken away; and Fig. 4 represents a detail top plan view of said airvalve seat and its adj Listing-sleeve.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the body of the vaporizer, and B is the mixing-chamber within said body, as shown in Fig. 2. The upper end of said mixingchamber is connected to the cylinder of the explosive-engine, as is common in devices of this kind.

lVithin the mixing-chamber B is arranged a hydrocarbon-valve shell 0, which is made integral with the vaporizer-body A and is provided with a hydrocarbon-chamber D, as shown in Fig. 2.

Integral with the vaporizer-body A is made a hub or projection E, provided with an internal channel F, which is connected in a suitable manner to the hydrocarbon-supply tank, as usual. From the channel F leads a conduit G to the hydrocarbon-valve chamber D, as shown in Fig. 2.

In the lower portion of the hydrocarbonvalve shell C is arranged a tapering valve" seat H, which is normally held closed by means of a spring-pressed conical valve I. (Shown in Fig. 2.) The internal portion of the valve-shell C is screw-threaded and its upper end closed by means of a screw-threaded plug K, as shown.

Within the internally-sorew-threaded portion of the valve-shell O is arranged a screwthreaded nut L, which is centrally perforated for the guidance of the hydrocarbon-valve stem 2', as shown in Fig. 2.

M is a coiled spring which surrounds the valve-stem t between the under side of the adjustable nut L and the upper end of the hydrocarbon-valve I, as shown. By adjusting the position of the nutL any desired tension on the spring M may be obtained.

In the lower portion of the mixing-chamber B is made a cylindrical perforation N, in which is vertically adjustable the annular air-valve seat 0, upon which the air-supply valve P is normally supported, preferably by gravity. To said air-valve P is attached or made integral with it a downwardly-projecting stem Q, which is guided in a verticallyperforated hub 0, made integral with the valve-seat O, as shown in Figs. 2 and 4.

For the purpose of limiting the upward motion of the air-inlet valve P, so as to insure a constant and equal lift of the said air-inlet valve during the running of the engine and to prevent an undue supply of hydrocarbon, I prefer to attach to the lower end of its stem Q a headed screw or projection q, adapted to come to a stop against an adjustable annu lar screw-threaded sleeve R, which is screwed into a screw-threaded recess in the hub O of lated by the operator for the purpose of ver-.

tically adjusting said sleeve S, its valve-seat O, and air-valve P relative to the lower end of the hydrocarbon-supply valve I during the running of the engine and by such adjustment determine and regulate the proper proportions of air and hydrocarbon to be admitted into the mixing-chamber B.

' After the sleeve S has been vertically adjusted for the purpose above stated it may be secured in position, preferably, by means of a clamping-screw S going through slitted ears S S made integral with the body portion A, as shown in Figs. 2 and 3.

Below the air-supply valve P is arranged the air-chamber T, which is in communication with the air-supply pipe U, as is common in engines of this kind.

In communication with the mixing-chamber B is arranged an air-supply valve V, provided with a regulating adj nstable val ve-plu g W for the purpose of regulating such additional supply of air to the mixing-chamberB as may be required during the running of the engine. 7

In explosive-engines to which my improved vaporizer is applicable a vacuum takes place in the explosive-chamber of the engine during the outward stroke of the piston of said engine, causing at such time a vacuum to be formed in the mixing-chamber B of the vaporizer, and thereby causing the valve P to be lifted from its seat 0 and caused to come in contact with the lower end of the hydrocarbon-supply valve I, which is thereby raised upward against the influence of its spring M, thereby adjusting the desired supply of hydrocarbon from the conduit F, connected to the hydrocarbon-supply tank, at the same time as atmospheric air is admitted from the pipe U and drawn into the mixing-chamber B through the annular valve-seat 0, thus causing the air and hydrocarbon to be thoroughly intermixed before being fed to the eX- plosive-chamber of the engine.

By having the hydrocarbon-supply chamber and its valve arranged within the mixingchamber B and arranged in a linear direction centrally above the air-supply valve P the air from the latter is caused to pass directly upward and around the hydrocarbonsupply valve, thereby causing a more thorough intermixing ofthe air and hydrocarbon, and consequently more perfect vaporization of the latter.

By placing the air-valve in position from below the hydrocarbon-valve it enables me to arrange the hydrocarbon-chamber containing the hydrocarbon-supply valve within the mixing-chamber B and integral with the body A of the vaporizer, by which I am enabled to supply the hydrocarbon at a very low point, thus permitting the use of a deeper hydrocarbon containing tank particularly advantageous in connection with engines for llaudnches, where a limited vertical space is Byadj usting the position of the sleeve S, its valve-seat S, and its valve-seat O the air-valve P can readily be adjusted relative to the lower end of the hydrocarbon-supply valve I for the purpose of regulating the supply of hydrocarbon relative to the air-supply as maybe needed from time to time, and such adjustment can be readily made during the running of the engine simply by taking hold of the flange S of the sleeve S and turning it to the right or left, as circumstances may require. I

Having thus fully described the nature, construction, and operation of my invention, I wish-to secure by Letters Patent and claim 1. In a vaporizer for explosive-engines, the combination with a shell in communication with the engine and provided with a pair of air-inlets and a mixing-chamber, of a val-veshell arranged in said mixing-chamber, in comm ufiication with a source of hydrocarbonsupply, and provided with a valve-seat, a pln g for closing the top of said valve-shell, a springactuated valve operating through said valveshell and engaging the seat thereof, an airinlet valve engaging said springactuated valve for operating the same, an adjustable valve-seat for said air-inlet valve, a hub con nected to said adjustable valve-seat, a sleeve integral with said hub for adjusting said airinlet-valve seat, and a sleeve adjustably secured within said hub for limiting the movement of said air-inlet valve.

2. In a vaporizer for explosive-engines, a shell provided with air-inlets and a mixingchamber, said shell in communication with the engine, a regulating-valve mounted in one of the said air-inlets, a valve-shell projecting in said mixing-chamber and communicating by a port with a source of hydrocarbonsupply, said valve-shell beinginteriorly screw= threaded, a plug for closing the top of said shell and having in its lower end a recess, a guide-nut secured within the said valve-shell, a valve-stem arranged in said valve-shell and operating through said nut and in said recess of the plug, a valve formed integral with the lower end of said shell and operating through the bottom of the latter,- a spring mounted upon said stem between said valve and said guide-nut, an air-inlet valve, a stem suitably connected thereto, an adjustable valve-seat for said air-inlet valve, a hub formed integral with said valve-seat and adapted to have the valve-stem of the air-inlet valve operated therethrough, means .formed integral with said hub for adjusting said valve-seat for the air-inlet valve, and means adjustably secured within said hub and engaged by the valvestem of the air-inlet valve for limiting the movement of the latter, substantially as herein shown and described and for the purpose specified.
