PATENT CARL H. BLOMSTROM, OF MARQUETTE, MICHIGAN, ASSIGNOR TO LAKE SHORE ENGINE WORKS, OF SAME PLACE.
GOVERNING MECHANISM FOR INTERNAL-COMBUSTION ENGINES.
SPECIFICATION forming part of Letters Patent No. 680,1 16, dated August 6, 1901. Original application filed November 8, 1898, Serial No- 695,912. Divided and this application filed March 23. 1901. Serial No. eager.
To all whom it may concern.-
Be it known that I, CARL H. BLOMSTROM, a citizen of the United States, residing at Marquette, county of Marquette, State of Michigan, have invented certain new and useful Improvement-s in Governor Mechanism for Internal-Combustion Engines, of which the following is a full, clear, and exact description.
The subject-matter of this invention was originally disclosed in an application filed by me on November 8, 1898, Serial No. 695,912, and of which the present application is a division.
The object of the invention is to provide an automatically-operating governor of simple and effective construction whereby uniformity in the speed of internal-combustion and like engines may be maintained.
The invention consists in the features set forth in following descriptiomdisclosed in the accompanying drawings, and particularly pointed out in the appended claims.
In the drawings, Figure 1 is aview in vertical elevation of an engine provided with my improved governing mechanism. Fig. 2 is a View in elevation showing the details of a flywheel governor.
The invention is shown applied to a form of two-cycle upright explosive-engine such as is commonly used for marine purposes. It will, however, be understood that it may be applied to any preferred type. The governor is shown as applied to regulate the throw of the mixing-valve, which controls the admission of air and fuel to the engine, but the construction of the fly-Wheel governor is clearly applicable for controlling the operation of other actuating parts of the engine.
The engine is mounted upon a suitable base-plate 10, upon which is carried the inclosing crank-casing 11 and the upright cylinder 12. The cylinder 12 is provided with a suitable exhaust-passage 13, and upon one side of the crank-chamber is mounted a suitable mixer or vaporizer opening into such crank-chamber. The type of engine disclosed is of the two-cycle type, in which the charge is first drawn into the crank-chamber and then forced into the cylinder of the engine;
(No model.)
but it will be understood that the invention is equally applicable to engines operating on other cycles.
The construction of the vaporizer has been fully set forth in a companion application filed by me of even date herewith, Serial No. 52,606, and need not be specifically described here. It is sufficient to state that the vaporizer consists of a tortuous passage 14, formed in a casting 15, which is suitably bolted over an opening in the crank-chamber. The tortuous passage 14, through which the charge is drawn by the suction of the engine-piston, is provided with a downwardly-opening oil inlet or nozzle 16, provided with a suitable throttling needle-valve l7. Beneath the oilinlet 16 is located a downwardly-opening suction-valve 18, provided at its upper end with a conical portion 19 for controlling the oilinlet and directly beneath said conical portion with a disk 20, which serves to obstruct the air-inlet passage. The stem of the valve 18 is guided in a suitable boss 18, threaded into the body of the mixing-chamber and exteriorly projects to a slight extent. An interposed coiled spring 20 serves to hold the valve in its seat.
As will be readily understood, the valve 18 is automatically operated by the suction of the engine-piston and serves to control the admission of the mixed air and fuel charge. In order to obtain uniformity of speed for the engine, I provide means for regulating the throw of the valve 18, which consists in a shiftable abutment 21, mounted beneath the endof the stem of valve 18. This shiftable abutment 21 is provided with diagonal slots 22, within which project pins 23, secured to the body of the vaporizer. It is obvious that as the abutment is shifted to and fro it moves nearer to or farther away from the end of the valve-stem, and thereby regulates the throw or extent of opening of the valve 18. Means are provided for automatically actuating the abutment 21, comprising a spring-held lever 24, pivoted intermediate its ends to a fork 25 upon the engine-frame, secured at one end to the abutment 21 and arranged with its opposite or free end in proximity to the engineshaft 26 and fly-wheel 27. The fly-wheel is recessed on its inner face intermediate its hub and rim, in which recess is located the centrifugal governor.
The governor comprises a weighted bellcrank lever 28, pivoted, as at 29, to the inner face of the fiy-Wheel and arranged to swing in the plane of the fly-wheel against the tension of a coiled spring 30, interposed between its weighted end and a pin 31. A second lever 32 is pivoted between ears 33, secured to the face of the fly-wheel near its periphery, so as to swing in a plane at right angles to the plane of the fly-wheel. This lever 32 extends inwardly toward the hub of the fly-wheel and is forked at its inner or free end, as at 34. It is provided intermediate its ends with an inclined cam-slot 35, within which projects the rounded free end 36 of the weighted bell-crank lever 28, so that as the latter is swung in a transverse plane by the variations in speed of the engine the lever 32 will be swung in aplane at right angles to the plane of the fiy-wheel. Upon the hub of the fiy-wlieel is mounted a loose sleeve 37, which is pivotally connected to the forked end of lever 32, so as to rotate with the fly-wheel and connected parts, but
free to slide in a longitudinal direction as the levers 28 and 32 are swung under the influence of centrifugal force. The arm or lever 24 is so positioned as to be engaged by the inner face of the sliding sleeve 37 andto be actuated thereby, so that the abutment 21 is automatically shifted to regulate the throw of valve 18 should the speed of the engine at any time vary from that at which it is set to operate.
It is obvious that the details of invention may be varied by the mechanics skill without departure from the invention.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In governor mechanism for internal-combustion engines, the combination with the engine-shaft and fly-wheel, and with a suctionvalve controlling the charge admission to the engine of a shiftable abutment for variably regulating the throw of said valve, a lever pivoted intermediate its end to the engine-frame, connected at one end to said abutment and arranged with the opposite free end adjacent to said shaft and fiy-wheel, a longitudinallymovable sleeve carried on the shaft in operative relation to the free end of said lever, a link pivoted to said fly-wheel and to said sleeve, and a centrifugally-operative arm carried by the fly-Wheel and operatively connect ed to said link.
