Application filed April 29, 1901. Serial No. 57,971. (No model.)

To 50% whom, ii /may concern;

Be it known that I, ERNEST H. KORSMEYER, a citizen of the United States of America, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Governing and Valve-Operating Mechanism for Gas or Vapor Engines; and I do hereby declare that the following is a full,clear, and exact deseription of the invention, such as will enable others to make and use the same, reference being had to the accompanying drawings, forming a part of this specification.

The object of my invention, primarily, is to open the exhaust-valve in a gas-engine at each alternate stroke of the piston after each explosion of the gas and control its speed and cause the spark ignition only when. necessary; second, to regulate the speed of the engine.

The invention consists in the novel construction and combination of parts, such as will be first fully described, and specifically pointed out in the claims.

Similar letters of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, A represents the hollow cylinder of a gas or vapor engine in which the energy is obtained from repeated explosions of gas mixed with air in the wellknown manner. Said cylinder is supported by a horizontal base-plate a, which is integral with the cylinder and arranged in position a short distance above the level of the ground. With each side of said base-plate are connected the upwardly-extended side supporting-plates a a, the upper ends of which side plates are bent inwardly at right angles, and secured to the base-plate by the bolts a and nuts a a is the water-jacket upon the outer side of and shown extending about two-thirds the distance around the cylinder A. Through the lower portion of the cylinder A at a point equidistant from its ends is an exhaust-opening a which also extends through the base-plate a. Extending from the exhaust-opening a in a transverse direction to the cylinder is a chamber a for the suction of air in the igniter-cylinder, hereinafter described, the bottom a of which chamber is depressed a short distance below the plane of the upper side of the base-plate a. The outer end of the chamber a which extends a short distance beyond the line of the outer side of the water-jacket a is inclosed by a lateral extension or casting a, extending from the cylinder A and integral therewith through the water-jacket a and,a short distance therefrom, forming the upper side of said chamber a", and a vertical end plate (1 extending upwardly from the bottom a of the said chamber to the outer end of the casting a", in the upper portion of which end plate a is a circular opening a for the reception of the cylinder or casting of the igniter, hereinafter described.

B represents the casing for the exhaustvalve, which consists of an annular box b slightly larger in circumference than the exhaust-opening a and having a bottom Z) and a chamber 6 In the top of the said box is a circular opening I) for the valve, the sides of which opening are inclined. In the opening 19 is seated a valve 1). Through the side of the box 1) extends an opening 19 With the bottom 6 of box I) is connected a downwardly-extended annular casing b, the sides of which are inclined inwardly toward the lower end. In the bottom 5 of the box Z) is an opening 19 through which extends the upper end of a valve-stem 11 which also extends through valve 1) and is secured to the said valve by the nut b. The lower end of the valve-stem extends downwardly within the casing b and a considerable distance below the lower end of said casing and is screwthreaded, and upon said screw-threaded end is fitted a nut Z1 Extending downwardly from the under side of said nut are forked portions Z9 Extending around the stem 6 and between the lower end of the casing b and the nut Z9 is a spiral spring I). The upper end-of the box Z) abuts against the under side of the bottom a of the chamber a upon one side and the annular flange a, which extends downwardly an equal distance from the under side of base a, upon the under side of the opening a as shown in Fig. 2, and which extends around the opening a to said bottom a Said box b is retained in position by the horizontally-extended flanges Z9 extending from the sides of said box, as shown in Fig. 1. \Vith the under side of base a are connected the upper ends of the rods b b the lower ends of which rods are screw threaded and extend through the flanges b, and upon said rods beneath said flanges are nuts 11 b".

0 represents the operating mechanism for the engine,which consists of a longitudinallyextended bracket-stand c, which is arranged near the side of the water-jacket a in a vertical position and in a parallel plane with the outer face of the end a to the chamber a'. Extending from the ends of bracket 0 downwardly are supports or standards a c, which rest upon the upper side of the base-plate a of cylinder A, and upon the lower ends of said supports are the lateral or foot supports 0 0 which are bolted to the base-plate a by the bolts 0. which pass through said flanges and also secure the base a to the upright base-supporting plates at a. The inner edges 0 0 of the supports 0 c are curved inwardly in the arcs of circles to admit the face-plate upon the igniter-cylinder, hereinafter de-.

scribed. At the rear end of plate 0 and extending laterally from the upper and lower edges of said plate a short distance from its outer face are the guide-flanges 0 0 the outer ends of which flanges are bent at right angles and extended toward each other a short distance, forming thereby a guide box or bearing in which reciprocates the main or governor-supporting plate D. The forward end of the guide-box extends about one-third the distance toward the forward end of said plate 0, and the main reciprocating plate D is equal in length to about one-half the length of said plate 0. Said main plate consists of a hollow casting, (shown in detail in Fig. 8,) through the rear end of which extends transversely one end of a stud-shaft d, the other end of which shaft 01 extends through the outer side of the plate D between the inner edges of the sides of the flanges 0 0 which form the boxing for said plate, and a short distance beyond the outer side of said flanges.

E represents the main driving-shaft of the engine, which is shown in section in Fig. 1, and upon which is an eccentric-plate e,around which extends the ring 6, made in two parts and secured together by the bolts e and nuts e With the ring 6 is connected one end of an eccentric-rod e, the other end of which rod extends to the stud-shaft cl on the reciprocating plate D and is pivotally connected therewith.

WVithin the hollow casting or plate D is a movable plunger-bar F, one end of which bar is pivotally connected with the stud-shaft d. The other end of said bar extends a considerable distance beyond the forward end of plate D or so far as to contact with the valveoperating slide -bolt, hereinafter described, when actuated at the proper time. The forward end d of the hollow casting or plate D, extending a short distance downwardly from the plane of its top, is curved rearwardly, as seen in Fig. 8. In the forward end of said bottom portion of the hollow casting or plate D is a longitudinal opening d Upon the under side of the portion of plunger-bar F within the hollow casting D is a tripping-plate f, which extends downwardly through the opening d in the bottom of the hollow casting or plate D and a short distance below the plane of the under side of said plate and which engages with the gas-igniting devices, hereinafter described, the lower end from the forward side being curved or inclined, as at f. The upper edge of the main supporting plate or stand 0, extending from an intermediate point upon said edge to the forward end of plate 0, is cut away on a plane a short distance below the plane of the top flange c of the boxing for the sliding plate D. Upon the outer side of said forward end of plate 0 is a roller casting or box G, which extends rearwardly a short distance and in which is the longitudinal opening g, which extends part way in width toward the plate 0, and near said plate 0 the upper and lower sides are contracted in width, as at g in Fig. 11. Within the openingg is a sliding bar H, in the outer side of which bar, at its forward end, is a pin h, which enters a notch h in the IIO outer side of theboxing G and limits the play of the bar H rearwardly. In the rear end and under side portion of the bar II is a notch 7L2. Upon the inner side of barH and within the opening g in the box G is a pawl I, which consists of a narrow plate, upon one side and end of which is a pivot 2', which enters a perforation h in the inner side of said plate, (see Fig. 3,) located at a point about equidistant from the ends of bar H. The outer end of said pawl is curved downwardly in a slight degree and is obliquely inclined at the extreme outer end.

In the inner sideof bar H is a pin t which is located near the pivot i on pawl I in the direction of the forward end of bar H. Around the pin 2' is a spiral spring i one extended end portion t of which extends to the side of pawl I and is bent at right angles and inserted within said pawl. The other end of said spring extends in an opposite direction and is bent at right angles and extended within the side of the bar H. Between the upper side of the plunger-bar F and the inner side of the top of the hollow casting or plate D is a spiral spring J.

In the outer side of the main supportingplate 0 in a vertical line with the forward support 0 to said plate and below the plane extended from the under side of box G is a stud k upon which is a triangular-shaped carn K, having three faces 7c 7c 70, upon which the outer end of plunger-bar F, contacts. Upon the outer side of the cam K are separate pins 7a 7a k, located near the angles formed by the respective sides of the cam. Upon the inner side of cam K is a ringk upon the outer surfaces of which, at a point intermediate the line of the angles formed by the respective sides of said cam, are alternating cam-teeth k and which are formed by lines extending longitudinally to said ring, as seen in Fig. 10,

,and with which cam-teeth the pawl I a1ternately engages. The outer end of the studshaft 7r; is screw-threaded, and upon said end isascrew-threaded cap 7r. Extendingaronnd the studshaft 7c, between the cap and the cam K, is a spiral spring 7.0 the tension of which is regulated by the cap 76*.

In the outer side of the hollow casting or plate D, at its forward end, is a longitudinal opening (Z which is upon one side of the plunger-bar F, and in which openingis pivoted at d to the outer side of the plate D one end of a vibrating barbed stem L, upon the outer end of which stem is a hook or barb Z, the forward end of which hook is rearwardly in clined, as at l, and which hook extends to and engages with the pins 7t 7t 70 on the cam K alternately. Between the upper side of the stem of hook L and the upper side of the open ing d is a spiral spring Z Upon the upper side of the box G is the speed-regulating device M, which consists of a vibrating plate m, pivotally connected at one end to the lugs g g on the forward end of the said box, the other end of which plate extends rearwardly a considerable distance beyond the vertical plane of the rear end of box G or so far as to be met by the extended arm upon the governor,hereinafterdescribed, and upon theunder side of said end is a downward extension or hook m, which is located a short distance from the rear end of box G, on the lower inner side of which hook is a slight inward projection or lip m In the rear end of the sliding bar H and near the upper side of said bar is a transverse groove h, with which the lip on on plate m is made to engage at the proper time.

On the top of box G, near the rear end, are lu gs n 72., extending upwardly a short distance, upon the upper ends of which is secured by screws 11 n the transverse plate N. With the vibrating plate in is connected one end of a rod if, the other end of which rod extends upwardly through an opening a in plate N and a considerable distance above said plate. The upper end of rod 17. is screwthreaded, and upon said end is a not a and a lock-nut n Extending around the rod n, between the nut n and the plate N, is aspiral spring 91 On the rod 01 between plates m and N, is a washer or cushion n 0 represents the governor, which consists of a vibrating standard 0, the lower end of which standard extends within an openingo in the upper side and near the forward end of the reciprocating plate D, as seen in Fig. 8, and is secured therein by the pivot 0 With the standard 0, ashort distance above the top of the plate D, is connected one end of an arm 0 the other end of which arm extends to a position above the upper side and rear end of the vibrating plate m, the forward end of said arm being bent downwardly at an angle and extended nearly to the said plate. Upon the upper end of standard 0 is a weight 0 Between the arm 0 and the top of the hollow casting or plate D is a spiral spring 0 Upon the other side of the standard 0 and extending in an opposite direction to arm 0 is a short arm 0 the outer end of which is bent at right angles and extended downwardly nearly to the upper side of plate D.

P represents the gas-ignitingdevice, which consists of a front plate 1), the ends of which are formed in arcs of circles and of the proper dimensions to extend within the curved inner edges o c of the supports 0 c to the main supporting plate or stand 0 and contact with the outer end a" of the chamber a". Through the ends of plate 19 are openings 19, (see Fig. 6,) in which are inserted the screw-bolts 19 which extend within the screw-threaded open ings (Win the lugs (r on each side of the end a to the chamber a, as seen in Fig. 12. WVith the inner side of plate 1) is connected a cylinder 13 which extends through the opening (1 in the end a of the chamber 611 3116. within the upper part oi said igniter-chamher and nearly to the inner side of cylinder A. Through the plate 19 and longitudinally through the cylinder 12 extends an opening IIO a point a short distance below the rod r 19 which is located above a transverse line extending through the center of the cylinder and in which opening is a rock-shaft 19 the ends of which extend a short distance beyond the outer side of plate 1) and the inner end of the cylinder 10 respectively. Upon the outer end of shaft 99 near the plate 13, is an upwardly-extended arm 19 which is perforated transversely. Upon the inner end of shaft p is an arm 29 In the outer end of the arm 19 is atransverse openingp in which is inserted a copper or non-corrosive-metal bushing 19*, the ends of the opening 19 being reamed, so as to permit of the outward-flaring ends of the bushing. The inner sides of the bushing 19 are circular in cross-section, in which bushing is forced a contact-pin 19 which is rectangular in cross-section. Through the plate 10 and longitudinally through the cylinder 19 extends a stationary tapering pin q, insulated from the cylinder 19 by suitable insulation, the ends of which extend a short distance beyond the face-plate p and the inner end of the cylinder p respectively. The outer end of pin q forms a binding-post for an electric wire, in which is a transverse opening q for the end of one of the wires from asuitable battery, (not shown,) the other wire being contacted with the cyl inder p or the engine. In the end of pin q is a screw (1 for securing said wire in the binding-post. On the inner end of pin q is a contact point or pin g which is the same as pin p and contacts with the pin 19 on the arm 19 of the rock-shaft 19 On the outer side of plate 19, near the bottom of said plate and also toward the forward end of said plate, is a stud-bolt 1", upon which is pivoted one end of a fiat plate r, the upper end of which plate extends the height of the arm 19 on shaft 19 and is slightly curved upon its rear side. Through the upper end of plate 4" extends one end of a bolt r which is screwthreaded at both ends. The other end of bolt 7' extends loosely through the opening in the arm 19 on shaft 10. Upon one end of bolt 7- is a nut r which bears against the forward side of the plate 0, and upon the other end of said bolt is a nut 0, which bears against therearsideofthearmp. Extendingaround shaft 19 between the arm 19 and the plate 19, is a spiral spring 19 one end p of which extends to a position on the forward side of the arm 19 and is extended part way around said arm. The other end of said spring is connected with a pin 19 on the outer side and with the rear end of said plate. With the pivoted plate r is connected a bolt r at a I/Vith the bolt r is connected one end of a spiral spring T the other end of which spring is connected with a pin 4, inserted in the front side of the forward support 0 to plate 0, a short distance below the stud 76, supporting the cam K.

Upon the inner side of the vertical supports a a to the base a, as seen in Fig. 2, are shaftbearingsss, (see Fig.2,)on whicharejournaled the opposite ends of arock-shaft S,which is beneath the forward end of cylinder A. Upon said shaft are oppositely-extended lever-arms 8 s Beneath the arms 3' s is a horizontal beam 3 one end of which beam extends to a position beneath the nut b on the exhaustvalve B and between the forked extensions Z9 Z) of said nut. With the beam 8 at a point intermediate its ends, is connected pivotally a link 8 the other end of which link is connected pivotally with the outer end of arms .9 on shaft S. In the outer end of arm 5 is an opening 8 in which is inserted the upper screw-threaded end of a rod 5 upon which rod, beneath the under side of said crank, is a nut 8 In the outer end of the beam .9 beneath said rod 5, is a cup-shaped bearing 8 in which the lower end of rod 5 is inserted. With the end of rock-shaft S which is toward the side of support a upon which the valve-operating mechanism is located is connected one end of a lever T, the outer end of which lever contacts with the outer end of the sliding bar H in the box G on the forward end of plate 0. In the bottom a of the chamber a, beneath the cylinder A, is a valve-opening u, with which is connected upon the under side of said bottom a an airvalve U, which is precisely the same in construction as the exhaust-valve B, the spiral spring it to said valve U being weaker than the spring Z9 of the exhaust-valve B.

In operation power is communicated to the main shaft E, which is an ordinary crankshaft of the engine operated by pistons in the cylinder (not shown) in the well-known manner from the successive explosions of gas in the cylinder A, and which is generated by an ad mixture of air which is drawn through the valve-openingu upon the opening of the valve U to the chamber a. Any kind of a gasmaking device may be connected with valve U. The rotation imparted to shaft E com municates a rotary movement to the eccentric e and also a reciprocating movement to the rod 6 which is also imparted to the plate D. As the reciprocating plate D moves forward inits initial stroke, the position of the cam K being in the position as seen in full line on Fig. 5 or that of the plunger F, bears upon one of the sides of the earn, the forward end of the plunger will pass beneath the rear end of the sliding bar H. Upon the said forward movement of the reciprocating plate D the action of the pistons in the cylinder takes in sufficient air through the valve U to mix with the vaporized gasolene or gas in the cylinder in readiness for the explosion. Upon the partial rearward movement of the plunger-bar F the pistons compress the gas, and in full rearward movement to the position, as seen in Fig. 4, the tripping-platef meets the upper end of the vibrating plate 1-, which moves forwardly under the tension of the opening 7* and releasing its control of the bolt 1' and moves upon said bolt sufficiently to permit the action of the spring 12 the end 19 of which throws the upper end of the arm 19 on the rock-shaft p rearwardly, which actuates said shaft and draws the pin 19 into contact with pin g within the cylinder A. In the same rearward movement described of plate D the hook Z engages with one of the pins 7t" on the cam K and partially rotates said cam and also elevates the plunger F, which then bears upon one of the angles of said cam, the tripper-plate fon said plunger-bar releases the pivoted plate 1'', which instantly moves forward to its normal position under the tension of -the spring r and contacts with the nut r drawing the arm 19 on the shaft and throwing the contact-points p 11 away from each other, and the said contacts being in an electric circuit produce a spark. The air and gas being then under compression, the spark ignites the gas and an explosion follows, the result energizing the shaft E. Following the explosion of gas the plate D again moves forward the plunger-plate, which being elevated by the angle of cam K strikes the sliding bar H, moving said bar forward, also vibrates the lever T, causing a partial rotation of the rock-shaft S, which action raises the arm .9 upwardly and forces up the valvestem b lifting the exhaustrvalve b, which exhausts the burned gases from cylinder A, and the cylinder is prepared for another charge of air and gas. In the backward movement of the plate D the spring 12 of the exhaust-valve B raises the forward end of beam 8 causing a partial rotation of shaft S in an opposite direction and causing the upper end of lever T to throw the slide-bar H in the direction of the plate D into a position for the action of the plunger-bar, the rearward movement of bar Hbeing checked by the pin h upon reaching the notch 72, in the box G. In said rearward movement of bar 11 the pawl I meets one of the teeth 7.5 on the rear side of cam K, causing a partial rotation of said cam andloweringthe forward end of the plungerbar F in a position to miss the sliding bar H in the next forward movement of plate D. Thus it will beobserved that in each forwardand-backward movement of plate D the action of the hook L and the pawl I causes a partial rotation alternately of cam K, and the plunger-bar F alternately strikes the sliding bar H and enters the notch 71 in the rear end of said bar and respectively operating the exhaust-valve to free the burned gases in the forward movement of plate D and tripping the igniter in a partial rearward movement of said plate until a certain degree of speed of the governor will throw down or lock the plate m and prevent a rearward movement ofthe slide-bar H. As the speed of the engine increases and its movement causes the plateD to reciprocate at a rapid pace the vibration of the governor 0 causes the arm 0 to contact with the vibratingplate m with sufficient force to throw the end of said plate downward1y,and at the moment the slide has moved forward to open the exhaust-valve the projection orlip m on said hooked portion m of the vibrating bar enters the notch h in the rear end of bar H, and the bar is locked or retained from movement and the exhaust-valve kept in an open position until such time that the speed of the engine decreases and the vibrations of the governor are lessened and the power of spring a on the rod 12 overcomes the engagement of the lipm with the sliding bar H, when the vibrating bar raises in position and releases said bar for contact with the plunger-bar F and at the same time closes the exhaustvalve b". In order to increase the speed of the engine, the nut 11 is turned upon rod n so as to increase the tension of spring a which action requires a stronger vibration of the arm 0 of the governor to actuate the vibrating plate at and retard the action of the sliding plate H, as seen in Fig. 5. When the tension of spring a is adjusted, the lock-nut n retains the nut 07, from movement. The successive stages of action in a gas-engine are thus under intimate controland economizing the power which ordinarily is spent in unnecessary explosion of gas. The beam 8 ha ing suspended by the link 8 and adjustably balanced by the rod .9, enables the valvestem 1) of the exhaust-valve B to be moved upwardly in position to raise the valve without binding or being moved laterally when the rock-shaft S is given a partial rotation, it being observed that the adjusting of the nut s on the rod 5 will change the position of beam 5 at an angle to the arms 3' s on'the rock-shaft S. In order to control the action of cam K, the tension is regulated by the cap k on stud-shaft 7t.

Itis obvious that instead of making the reciprocating plate D in the form of a hollow casting it may be of one thickness intermediate the top and bottom and the rod e and plunger F connected with the respective outer and inner sides of the plate.

Such other modifications may be employed as are within the scope of the invention.
