SPECIFICATION forming part of Letters PatentNo. 729,377, dated May 26, 1903. Application. filed September 30, 1902.' Serial No` 125.406. (No model.)
To all whom may concern: Y
Be it known that we, WILLIAM F. MEISTER and WINFIELD S. PATTIN, citizens of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented certain new and useful Improvements in a Combined Governor and Gas and Air Mixer for Explosive-Engines, of which the following is a specification.
Our invention relates to explosive-engines, and the invention consistsof a peculiar governor-valve adapted to feed a measured quantity of explosive'Ymixture to the compressionchamber. 'Y
The invention also consists vof the special detailsof construction hereinafter fully described,` with the novel features pointed'out'.
inthe claims'.
In order to enable others skilled -in the art to make and use our invention,'we will nowA proceed to describe its construction and operation with reference to the accompanying drawing, forming a part of this specification.
The figure shown by the drawing illustrates a central vertical longitudinal section throu gh our invention and -part of 'a gas-engine cylinder. Y Y
is in nature a valve, is'adapted to any compression type of explosive-engine.Y Since such Y engines are well understood,.wedeem a de.
tailed descriptionof the cylinder shown unnecessary, and therefore we .will only refer to such parts of the said cylinder as will make clear our invention as applied thereto.
In carrying` out our invention we employ an automatic valve adapted to feed air and gas to a compression-space, shown by our drawing as a jacket-space 1, which constitutes the compression-chamber, and, as shown, extends around one end of the cylinder. The explosive mixture passes to the explosive end of the cylinder through an inlet-port 2 of common andwell-known form.
With an engine employing a cylinder as above described in adapting our invention thereto we cut away the outer wall of the jacket, providing an opening 3, forming communication through our improved governorfrom the spirit of our invention. v17isl supported o n a reduced portion'of the f valve with the compression-chamber above referred to. In the make-up of our invention we employ a body portion 4, having an air-passage 5 and a gas-passage 6. The air-passage 5 may open direct with the outer air or be screw-threaded, as shown, adapted to form connection with the threadedend of an air-pipe.'A (Not shown.)
The Y gas-passage -6 extends along and' just .within the outer walls of the body portion 4, Vfrom'a gais-feed pipe 7, Ydown to and communicates with an annular space 8, encircling ings 1 1,`providing gas-outlets from the said annular space 8. Vithin the chamber 9 we `be enlarged, Vas at 9,we arrange a pistoni?, Y v having a reducedfportion 18,forming'anan It will beapparent that 'our invention, which nular gas-passage' around the piston. The special gas-'passage just described, formed by the reducedportion 1S, as' stated, maybe dispensedwith or modified without departing Thev piston stem 12, as shown, adaptedv when the valve 13 is on its seat 10 to afford maximum feed of gas and air, respectively, to the-passage 6 and the chamber 9.
It will be noticed that the lower surface of the body portion 4 is provided with a suitable offset 19, adapted to fit into the opening 3`in the side walls of the compression'chamber or jacket 1. The body portionw can be secured in place by tap-bolts 20, extended into the outer walls of the compression-chamber, or by other obvious means adapted thereto. IVith the above-described construction of parts and the arrangement thereof it is apparent that upon a backward stroke of the enginepiston a vacuum elfect will be produced in `the open end of av piston-chamber 9j The -openend of the chamber 9 is fashioned into la valve-seat 10, having aseries of jet-openarrange a stem- 12, having at its lower end? the compression-chamber 1 operating to draw and unseat the valve 13, with an obvious inrush of air tlnough the opening 5 and chamber i). At the same time gas willpbe forced through the passage 6 into the annular passage S and out through the jet-openings l1, meeting and mingling with the air, and thereby insuring a thorough mixture. The amount of explosive mixture fed into the compression-chamber l1 is governed by the tension of the spring 14. Should the engine speed beyond desired rapidity of stroke, increased vacuum would be formed in the compression-chamber, effecting to draw down or unseat the valve 13. The piston 17 being ixedly secured to the valve-stem 12, it is apparent when the valve 13 is unduly opened that it would move with the valve 125, and thereby correspondingly cut oii'f or throttle the supply of gas and air. Under normal conditions the tension of the spring will insure movement of the valve 13 and the piston 17, such as will allow only enough air and gas to pass into the combustion-chamber adapted to maintain a continuous and uniform stroke of the engine-piston.
Our invention involves special novelty in its simplicity of parts and improved means for feeding and mixing the air and gas that is not liable to get out of order or be disarranged by an unskilled attendant.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. In combination with an explosive-engine, a leras and air cut-oit or throttle consisting of a body portion having a piston-chamber-opening direct into the compression-chamber of the engine, an air-inlet leading into the said piston-chamber, a gas-inlet leading into the said piston-chamber and also down into an annular space around the lower or open end of the said piston-chanlber, a downwardly-movable spring-retained valve seated at and closing the lower end of the pistonchamber, a series of jet-openings leading through the said valve-seat from the annular space around the lower end of the pistonchamber, and with their lower or open ends adapted to be closed by the said valve when it is on its seat, and a piston adapted to move with the said valve operating to cut off or throttle the supply of gas and air, substantially as described.
2. In combina-tion with an explosive-engine, a valve-chamber opening into the compression-chamber of the engine, a yielding piston-valve in said valve-chamber operating to cut off, wholly or partially, supply of gas and at the same time, partially cut off the supply of air, an upwardly-seating yielding valve adapted t simultaneously cut off supply of air and gas at the compression-chamber openingof the said valve-chamber, a common valve-stem to which the said upwardlyL seating and piston valves have fixed connection, and a spring on the upper or projecting end of the said valvc-stem having tensionadjusting means, substantially as described.
In combination with an explosive-engine, means operating to cut olf or throttle gas and air supply, according to more or less vacuum produced in the compression-charm ber, the said cut-oli' means consisting of a casing having an inner chamber with inlet and outlet gas and air passages and openings as specified, a valve-stem in the said inner chamber having its upper end projected through the said casing, a regulating-spring, on the projected end of the said stem, a piston-va-lvc within the said inner chamber on the said stem, and a lower upwardly-seating valve united to and moving with the said piston-valve, substantially as described.
4. In combination with an explosive-engine, a gas and air cut-off employing a casing having an inner chamber, in direct communication with the engine compression-chamber and also inlet and outlet passages, and openings closed by a lower valve as specified, a piston in the said inner chamber united to and moving with said lower valve, the said piston being adapted in operationto cut o or throttle gas and air passages to the said lower valve according to the more or less vacuum produced in the compression-chamber of the engine substantially as described.
