Application led February 5, 1901. Serial No. 46,042. (No model.)
To n/ZZ wiz/om, z'f may concern.-
Be it known that I, WILLIAM G. STOLZ, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Valves for Explosive-Engines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making' a part of this speciiication and to the letters of reference marked thereon.
The present invention has relation to that class of valve-gear for explosive-engines in which the inlet-valve and the outlet-valve are arranged in line with each other. The object thereof is to provide means whereby the inletvalve may be forced from its seat and opened to supply gas to the engine-cylinder should the valve from any cause fail to act, attained by the mechanism substantially as shown in the drawings and hereinafter described.
Figure l ofthe drawings is a side elevation, partly in section, oi' an eX losive-engine embodying my invention. 2 is a top plan view, partlyin section. Fig. 3 is a detail sectional view showing the inlet-valve and the outlet-valve and the means employed for forcing the inlet-valve from its seat.
In the accompanying drawings, A represents the usual engine-cylinder in which the piston works, the rod a thereof being connected to the crank-arms b, which in turn are connected to the transverse shaft c CZ.
The valve-chest B has the usual inlet-valve C and the outletyalve D, the latter being operated in the ordinary manner by the cam E, with which the end of the valve-stem e engages, said valve being spring-actuated by means of the spring f. rllhe valve C is also spring-actuated through the medium of the coiled spring g, encircling the valve-stem 7L, so that the valve will be retained closed when in its normal position, as shown in Fig. 3 of the drawings.
The cam E, which may be of tho usual construction, is keyed or otherwise secured to a short cam-shaft t', which carries a gear-wheel j and a second cam F, said gear-wheel meshing with the teeth of a pinion 75 on the shaft d. The valve-chest B communicates with the supply through the pipe l, and the usual igniter G connects with the valve-chest between the valves C D and extends through the opening m. The outlet-pipe IVI connects with the valve-chest through the opening n in the eX- haust-chamber of the valve-chest.
The several parts and their construction herein described comprise the ordinary form of gas or explosive engine and is simply shown to better illustrate the application of my invention thereto.
The device or mechanism constituting my invention comprises the plunger-rod I, which is spring-actuated by means of the spring o, located between the end of the valve-chest 13 and the bearinghead p upon the end of the plunger-rod. A pivoted lever .I is brought in contact with the bearing-head p, said 1everbeing pivoted to ears q upon the end of a guidecasing K, suitably connecting with the valvechest B. A pitman-rod L operates the pivoted lever J by its outer end striking against said lever and forcing the end thereof against the bearing-headp and in turn forcing the end of the plunger-rodI against the end of the valve-rod h to open the Valve C should the valve stick to its seat and fail to operate in the usual manner. The spring o will return the rod I to its normal position and the spring r will automatically return the pitman-rod L to its former position necessary to be again operated upon by the cam F, thereby providing a very simple device or attachment that will insure the successful operating of the inlet-valve C at all times.
It frequently happens in explosive-engines that the inlet-valve becomes inactive by reason of said valve sticking to its seat, usually caused by the burned oils and gases which pass in and out of the cylinder and valve-chest and accumulating on the valve-seat in a gummy state and rendering the valve inoperative by suction alone. Therefore it is necessary to bring aid to the valve bya simple automatic means to assist it in its action when the valve resists the usual suction to open it.
The plunger-rod I and the valve-stem 7i are regulated in their length, so that the end of the plunger-rod will not strike the end of the valve-rod unless the inlet-valve fails to operate in its usual manner.
It is evident that many changes or modifi- Ido cations in the means employed for operating the inlet-valve may be made Without departing from the principle of the invention, and any suitable means may be provided for 0perating the pitman-rod, as circumstances require. f
Having now fully described my invention, what I claim as new7 and desire to secure by Letters Patent, is-
1. In an explosive-engine,- a suction inietvalve and a supplemental device for operating said valve should it fail to operate by suo# tion, said device comprising a spring-actuated plunger-rod arranged to strike the valverod, a pivoted leverarranged to strike the plunger-rod, and suitable means for operatingthe lever, substantially as and for the purpose set forth.
2. In an explosive-engine, a snetion inletvalve and a supplemental device for operating said valve should it fail to operate by suetion,v said device comprising a spring-actuated plunger-rod arranged to strike the valverod to force open the valve, a pivoted lever arranged to strike the end of the plunger-rod, and a spring-"actuated pitman-rod arranged to strike the lever, and suitable means for operating said pitman-rod, substantially as and for the purpose speoied.
3. In an explosive-engine, a suction inletvalve and a supplemental device for operating said valve should it fail to operate by suetion, said device comprising a spring-aetnated plunger-rod "arranged to strike the valverod, a pivot'ed lever arranged to strike the end of the plunger-rod, a spring-actuated pitman-rod arranged to strike the lever, and a rotatable cani for operating the pitman-rod, Substantially as and for the purpose described. In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses VILLIAM G. STOLZ.
