GOVERNOR MECHANISM FOR EXPLOSlVE-ENGINES.
$PECIFICATI ON formingpart of Letters IPatent No. 735,029, dated July 28, 1903.
Application filed February 26, 1902. Serial No. 95,706. (No model.)
To all whom it may concern.-
Be it known that IQVILLIAM J. WRIGHT, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and Improved Governor Mechanism, of which the following is a specification.
Myinvention is in the nature of a new construction of governor mechanism especially adapted for explosive-engines for controlling the inflow of the working agent to the working cylinder, and primarily it seeks to provide a very simple and inexpensive construction of this kind capable of being readily combined with the ordinary types of gas or gasolene engines and which will effectively operate for the intended purposes.
The invention consists in certain novel correlation and combination of parts, all of which will hereinafter be fully described, and specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a longitudinal section of a gasengine equipped with my improved, governor mechanism. Fig. 2 is a transverse section thereof,taken practically on the line 2 2 of Fig 1. Fig. 8 is a top plan view of the parts shown in Fig. 2. Fig. 4 is a horizontal section taken on the line at 4: of Fig. 3. Fig. 5 is a detail section on the line 5 5 of Fig. 2.
In the drawings I have illustrated my improved governor mechanism as applied to an engine having a valved intake at each end of the pump and working cylinders; but I desire it understood the construction of engine shown per se forms no part of this invention, as the same is fully disclosed in my copending application, Serial No. 95,097, filed February 21, 1902. Furthermore, the said governor mechanism may with a slight variation of parts be adapted for use on the ordinary type of explosive-engines. In the type of engine shown the same embodies a suitable base A, on one end of which is mounted the crankshaft B. At the other end the base A has a slideway afor the cross-head O, to which is joined the rod d of the piston D, that operates in the working cylinder E. On a pin P in the cross-head C is fulcrumed a bell-crank lever F, the endfof which is connected to the wrist-pin G on crank-disk of the shaft B, and the end f is joined with the rod h of the piston H, that operates in the pump-cylinder I, such arrangement of parts joining the two pistons D and H to operate in unison. It
- should be stated that in the construction shown the working cylinder is connected by the crossed converging tubes with the exhausts at each end of the pumping-cylinder,
so that as the charge is forced out of the' front end of the said pumping-cylinderit enters into the rear end of the working cylinder, and vice versa.
When joined with the type of engine shown, the governor mechanism is formed with a mixing-chamber 1 in a base having flanges 1 for securing it to like flanges h h on the pumpcylinder, and at each end the mixing-chamber has an outlet 1 1 controlled by a normally closing valve 1 that opens outward by the piston suction to allow for the escape of the working agent from the chamber 1 into the cylinder. Each outlet 1 is disposed over an inlet 72 for the cylinder H, the purpose of which will presently appear. Centrally the chamher 1 has a feed hub or extension 1, having flanges 1 to receive the flanges 2 of the feedtube 2, having a contracted bore 2 to receive a shiftable hollow valve 3, the upper end of which termigates in a closure member or seat 3 at a point above a series of jet-inlets 3. The valve 3 snugly fits the bore 2, and the said bore at the lower end of the tube 2 is enlarged, as at 2, to provide fora mixing-space surrounding the discharge or nozzle end 3 of the valve 3, as best shown in Fig. 2, by reference to which it will also be noticed adjacent the nozzle end 3 of the valve the tube 2 has a series of air-inlets 2 controlled by a horizontally-shiftable slotted collar 4, the adjustment of which controls the size of the inlets 2. (See Fig. 5.) At the upper end the tube 2 is also enlarged to form a gas-space 2 in which the seat and perforated end of the valve 3 plays, and into the space 2 discharges the gas or gasolene supply pipe 5. The valve 3 has a stem 3 that passes up through a gland 6 on the tube and carries at its upper end a grooved head 3 to receive the lugs 7 '7 on the bifurcated ends 8 of the short arm 8 of a bell-cranklever 8, fulcrumed in a bracket 9, secured to the outside of the tube 2. (See Figs. 2 and 3.) The valve 3 is normally held to its upper or maximum feeding position, as shown in Fig. 2, by a spring 9 or other equivalent means.
10 designates a shaft journaled in a bearing-box 2 formed integral with the base of to the tube 2 and disposed in a plane parallel with the bell-crank-lever arm 8*. At one end the shaft 10 carries a band-wheel 10 belted or otherwise geared with the crank-shaft B. (See Fig. 1.) To the other end of the shaft 10 is fulcrumed the centrifugally-operating lever-arms ll 11, carrying the ball-weights 11, and said lever-arms ll 11 have link members 11, that pivotally join with the grooved sleeve 12, slidable upon and rotatable with the shaft 10, and with said sleeve connects the bifurcated end 8 of the long arm 8 of the bell-crank lever 8, as clearly shown in Figs. 2 and 3.
At the point where the tube 2 discharges into the mixing-chamber 1 said chamber is provided with a screen 13 to clear the Working agent of the coarser particles of refuse that might pass in with the gas or gasolene.
From the foregoing, taken in connection with the accompanyingdrawings,itis thought the advantages of my improved governor mechanism and the operation thereof will be readily understood by those skilled in the art to which it appertains.
It will be noticed the gas or gasolene passes through the perforations in the upper end of valve 3 and down through the valve and discharges into the mixing-chamber at the point where the air enters, the flow of which can be increased or decreased by adjusting the slotted collar 4. As the engine speeds up the bell-crank 8 is shifted to depress the valve 3, and in so doing the feed-openings are cut off and the feed of gas or gasolene is proportionately decreased, and in case of an excessively high speed the valve 3 will be forced down until its seat bears on a corresponding seat 2 in the tube 2,and thereby shuts off all flow of the volatile substance. As the working agent passes into chamber 1 it is drawn alternately into the opposite ends of the pump -cylinder through the valved intakes thereto, and the pump action is such that as it is being drawn back of pump-piston in one movement thereof the prior charge at the front of'the piston is being forced into the proper end of the explosive-cylinder.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. The combination with the mixing-charm her, the tube 2 communicating with said chamber, having air-intakes, said tube having a gas or gasolene feed, a hollow valve slidable in the tube, and having an outlet discharging in the tube at the air-intake end, said tube having a valve-seat, the valve having a seat for cooperating with the tube valveseat, and inlets at a point belowits seat, and means connected with the valve and geared with the engine-shaft controlled by the varying speed of the engine, for shifting the valve to increase or decrease the flow of gas or gasolene therethrough, as set forth.
2. The combination with the mixing-chamber, the tube 2, discharging thereon, said tube having a gas-receiving chamber, and an air receiving chamber, divided by a contracted bore, the governor devices, including the shaft 10, the ball-levers 11,-the collar 12, and bell-crank lever 8; of the hollowvalve 3, slidable in the contracted bore, its lower end having a discharge, projected into the air-receiving chamber of the tube, its upper end having a cutofi seat, and inlets below the seat, said upper end having play in the gasreceiving chamber, of the tube, the said valve having a stem projected above the tube, a means for automatically forcing the valve 3 to its open or gas-receiving position, said stem having a connection with the bell-crank lever 8, as specified.
