GOVERNOR FoR Yens-EneINI-:5.
SPECIFICATION forming part of Letters Patent No. 589,583, dated September '7, 1897. v -llpplieation filed April 7, 1896. Serial No. 586,570. (No model.)
To n/Zl whom, t may concern,.-
Be it known that I, FEED W. SPACKE, a citi- ',:en of -the United States, residing at Indianapolis, in the county of Marion and State of Indiana, haveiuvented a new and useful Governor for Gas-En gin es, of which the following is a' specification.
Myinvention relates to an improifementin governors for gas-engines.
The object of my invention is toproduce a governor which will be very sensitive to changes of load, and also to produce a governor which will be particularly adapted for use on double-acting gas-engines, more particularly the engine described and claimed in my pending application, Serial No. 586,572, iiled herewith.
The accompanying drawings illustrate my invention.
Figure 1 is a plan view of the governor, showing also a central horizontal section of the engine shown in the above-mentioned application. Fig. 2 is aside elevation of the governor on -a larger scale. Eig. 3 is a section on line 3 3 of Eig. l. Fig. 4 is a sect-ion of one of the gas-inlet-valve-operating mechanisms. Fig. 5 is a similar view of the other'gas-inletvalve mechanism. Fig. G is a central horizontal section thereof. Fig. '7 is a detail of one of the admission-valves and its operating meehanism. Fig. S is a detail of a portion of the governor.
In the drawings, flindicates a cylinder in which is mounted apiston 10. A pair of ports 11 and 12 open one into each end of the `cylinder, and over said ports are secured, respectively, the valve- boxes 13 and 14. Each of said valve-boxes is provided with a chamber 15, which communicates with the corresponding port 1l. or 12 and is alsoprovided Wit-l1 an adm ission-chamber 1G and an exhaustchamber 17, each of said chambers communieating with chamber 15, and the communications therebetween being closed in box 13 by an admission-valve 1S and an exhaust-valve 1Q and in boX 14 byadmission-valve 2O and exhaust-valve 21.
' Mountedin suitable bearings on the engineframe is a shaft 22, which is connected to the crank-shaft of the engine by suitable means to cause the said` shaft to rotate at one-half of the'speed of the said crank-shaft. Each admission-'valve stem is provided at its outer end with an I-shaped head 23, and each exhaust-valve stem is provided'n-ith a head 24, Somewhat similar in shape.
Pivoted below each stem, is a lever 25, the upper end of vi hich is bilu rcated and arranged to engage one of the I-shaped heads of the Valve-stems. The lower ends of levers 25 are extended in position to be en gaged each bya cam 26, carried by shaft- 22, and one of a series of springs 27 is secured at one end to thelower end of each lever and at the other end to one of the valve-boxes, the whole arrangement being such that the movement of the piston will cause the valves to be intermittently opened, and the action of the springs will cause said valves to close.
Mounted between the admission-chambers of boxes I3 and 14 and communicating therewith is a mixing-chamber 2S, into which is led any suitable supply of air, in the present case the said supply coming from a chamber 29, which is formed between the middle portion of the pistou and the walls of the cylinder.
Each end of the mixing-chamber is enlarged, and opening into said enlarged portion is a passage 3], into which opens a suitable gas-inlet pipe Mounted in the inner end of passage 31 by means of suitable screwthreads is a valve-seat 33. Formed integral with the inner end of said seat are a pair of arms 34, which Carr)-Y about midway of their length a cylindrical guide 35, and connecting the ends of said arms is a cross-bar 36. A valve-stem 37 is mounted so as to slide through cross-bar 36, and the outer end of said stem is provided with a valve 3S, which is adapted to lit into seat and to thereby. close the opening between the gas-inlet. and the mix` ing-chamber. Secured to or formed integral with stem 37 is a collar 30, which is adapted' to fit and to slide longitudinally in guide 35, and a spring 40, mounted between collar 39 and cross-bar 36, tends to keep the said valve closed. A pin 41 is secured to collar 39 and extends through a slot- 42, formed in the guide. Iivoted to pin 41 is a lever 43, the outer end of which extends through a slot 44, formed in the outer wall of the mixing-chamber, and the inner end of said lever is adapted to be engaged either by an arm 45 or an arm 45, carried by a rock-shaft 46, which is mounted IOC in suitable bearings in the walls of the mixing-chamber and the ends of which project into said chamber. The outer end of lever 43 is provided at its upper and lower edges with a short spur 47. Secured to each I- shaped head 23 of each of the admission-v valve stems is a pin 48, the inner end of which is notched, as at 49, the said pins being each arranged so as to be adapted to engage the outer end of one of levers 43 when the corresponding` admission-valve is opened.
Mounted in a suitable bearing 50, secured to the walls of the mixing-chamber, is an up-l right governor-shaft 5l, which is provided atY its lower end with a gear 52, which meshes with a gear 53, carried by shaft Secured to the upper end of shaft 5l atopposite sides thereof are a pair of links 54, to the lower en ds of which are pivoted a pair of governor-balls 55, which are carried upon the upper ends of a pair of links 56, pivoted at their lower ends to a block 57, which is longitudinally movable on shaft 5l. Block 57 is provided with a flange 58, the upper surface of which is adapted to be engaged by two rollers 59, which are carried at the outer ends of a pair of arms G0, which are secured to rock-shaft 4G, the arrangement being such that a movement of the governor-balls away from the governorshaft will cause block 57 to move upward upon shaft 5l, and said movement of the block will cause shaft 46 to be rocked. Mounted upon the upper end of bearing 50 and arranged to be longitudinally movable thereon is a collar Gl, provided with a set-screw (32, by means of which the collar may be secured at any desired position on bearing 50. Mounted on the upper end of bearing 50, below collar Gl, and free to move on said bearing, is a plate 63, provided with a pair of oppositely-extending arms G4, to the outer end of each of which is secured one end of one of a pair of springs (55, the upper ends of said springs being secured one to each of arms GO, the said springs tending to restrain the outward movement of balls 55.
The ends of rock-shaft 4G, which project into the mixing-chamber, are provided with suitable screw-threads, onto which is screwed at one end a check-nut (56 and a short rod (57 and to the other end of which is screwed a similar nut 68 and a rod 69. Secured near the outer end of rod (57 and substantially at right angles thereto is an arm 45, and similarly secured .to rod 69 is an arm 45", the arrangement being such that the inner ends of levers 43 will engage with the arms 45 and 45l and will be held in contact therewith by means of the heavier outer ends of said levers. A pair of collars 70 are mounted, one on each rod 67 and 69, and are adapted to engage the outer walls of the enlarged portions of the mixingchamber.
The operation is as follows: The movement of the piston causes shaft 22 to rotate, andthe rotation of said shaft by means of gears 53 and 52 and shaft 5l causes the balls 55 to flyoutward and thereby raise block 57, the movement of said block causing the outer ends or' arms GO to move upward and thereby roei; shaft 46, said shaft in turn causing arms 45 and 45 to press down upon the inner ends of levers 43 and thus raise the outer ends thereof. Under ordinary loads the outward movement of the governor-balls is sufficient to cause arm 45" to so raise the outer end of its corresponding lever 43 that the said lever will be out or' the path of movement of the corresponding pin 48, while arm 45 will raise the outer end of its corresponding lever 43, but will not raise the said end out of the path of movement of the corresponding pin 48. The inwardopeningmovement of the admission-valves. caused by the rotation of shaft 22, cam 26, and the movement of lever 25, will therefore cause one of the pins 48 to engage with the outer end of l[he lever 43, which is engaged by arm 45. and will press the said lever inward, thereby opening valve 38 against the action of spring 4() and thus allowing a certain portion of gas to pass into the mixing-chamber, where it is mixed with the required quantity of air and from there drawn through the admissionvalve into the cylinder. The inward movement of the other admission-valve is precisely the same, but the outer end of the corresponding lever 43, which is controlled by arm 45". being lifted out of the path of movement or' pin 48, carried by said valve, the gas-inlet valve, which is operated by said lever, will not be opened, and therefore no new charge will pass into that end of the cylinder. Under ordinary loads, therefore, butV one end or' the cylinder is supplied with gas, and the engine operates as a single-acting engine. t' the speed increases sufliciently, arm 45 will lift its lever 43 out of the path of the corresponding pin 48, and there will be no new charge supplied to either end of the cylinder. If the load becomes heavy, block 57 is dropped by the balls 55 far enough to allow the lever controlled by arm 45 to drop down into the path of the corresponding pin 48, and gas will then be supplied to each end of the cy iinder, this arrangement continuing as long as the load is heavy enough to require the extra power. As soon as the load lightens the outer ends of both levers 43 are raised and that one which is controlled by arm 45" is again thrown out of the path of movement of its pin 48. Arms 45 and 45" may be set at any desired angle relatively to each other, so that any desired increase of load will cause gas to be admitted to both ends of the cylinder, and said arms may be so set that both ends of the cylinder will work even, if desired. It will be IOO IIO
i f W pivot-point of leve'rs 43 being lower than the pivot-point of arms l5 and 45 the inner vends of said levers 43 move out of engagement with arms l5 and l5 when pins 48 press the said `levers inward, so that the governor-balls are not hampered in their movement by the engagement of either one of pins i8 with its corresponding lever 43. This open connection between the gas-valve and the governor enables the governor to act upon each gasvalve entirely independently of the other, so that it is very sensitive to any changes of speed of the engine which may occur while one of the said valves is being operated by the corresponding admission-valve.
The outer ends of levers 43 are provided with spurs l? and the inner ends of pins 4S are notched, so that said pins will continue to engage with said levers until the said levers are entirely out of the path of movement of the pins. lfly this construction the upper and lower edges of the outer ends of the levers will not become rounded oft and thus cause the pins to miss the levers before they should do so. In order to increase the average speed of the engine, collar 6l is moved down upon the upper end of bearing 50, thereby increasing the stiffness of springs 65.
I claim as my inventionl. In a governor for gas-engines, the combination with the gas-inlet valve thereof, a lever pivoted to said valve, and means for operating said valve through the medium of said lever, of a rock-shaft, an arm carried by said rock-shaft and adapted to engage with one end of the gas-valve lever but independent thereof, and means controlled by the speed of the engine for operating said rockshaft, the arrangement being such that, when the gas-valve lever is moved so as to open the valve, the said lever will be moved out of engagement with the arm carried by the roekshaft, substantially as and for the purpose specified.
