GAS-E NGINE Specification of LettersPatent.
Patented Feb. 1s. 1` non.
Application filed August 2, 1907. Serial No. 386.852.
To all whomI it may concern.'
Be itknown that I, JOSEPH Seofr'rBnNsov' a citizen of the United States, residing at lowa City,'in the county of Johnson and State of lowa, have invented a new and use ful Gas-Engine, of which the following is a speciiieation.
This invention relates to internal, combustion engines,xand has for its ijn'ineipal object to provide a novel form of engine in which` provisionis made for effecting the introduction of an explosive charge at every second stroke ofthe piston, that is to say, once during each revolution of the crank shaft, as in a two cycle engine, or once during each two strokes of the crank shaft as in a four cycle engine. l
A further object of the invention is to provide an engineof this type in which the change from two cycle to four eyclcvtype, or from four cycle to two cycle may be instantly made, so as to be available in case of emergeney, as, for instance, in the driving of an automobile or launch, where the. two cycle type may be. made available for sudden spurts, while the engine, may be ordinarily run four cycle in order to economize in fuel.
VViththese and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the aecompanying drawings, and partieularlvpointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the. structure may be made without departing from the spirit or sacriiieing any ol' the advantages of the invention.
ln the accompanying drawings: Figure l is a sectional elevation of an internal combustion engine constructed in accordance with the invention. Fig. 2 is a side elevation of the saine, partly in section.
Similar numerals of reference are employed to indicate corresponding parts throughout the several iigures ol" the drawings.
The engine includes a base l() and crank case 11, these being of any desired construction, and the crank ease being provided, as usual, with bearings for the support of the crankshaft 12. i i i Above the crank case is a cylinder, iwhich conm'iunieates with the crank case by means of a transfer port 16, as in the two cycle. dn-
gine, and opposite the cylinder end ofthe valve 30 having a port 31 which may be moved to open or close the transfer' port. Projecting from the stem 32 of this valve is an arm 23', the outer end of whichis connected toy a vertically disposed rod 35, the lower end of which is guidedL in a bearing formed in a bracket 36 that projects from the cylinder.
Surrounding the stein 32 is a torsion s ring 37 that tends to maintain the valve in e osed position and which serves to effect the closing movement after each upward movement of theI rod 35. Extending from the rod 35 is a pin 40 which may be engaged by a cani lever 41 for the purpose oi raising the rod 35 and holding the same upiagainst the stress of the spring, so that the valve may be maintained in open position.
livoted at one side of the crank easing is a lever alli one end of 'which acts as a tappetfor raising the rod 35.. The opposite arm of the lever is provided with an eloi'igated slot for they 'reception of a pin 45 that projects from a disk to on the shaft 24 the arrange- 'meni being such tha t when the engine is operating after the manner of a four cycle engine the valve will be opened once during each two revolutions of the crank shaft. Yhen the parts are in the position shown in Fig. 1 the valve 30 is closed and the exploded charge is escaping through the port 17. fl'luring the next upward movement of the piston, the valve will remain closed and near the. conipletion of the next movement in the direction of the crank shaft the valve will be opened, so that a charge may enter the cylinder and be. compressed on the next out stroke of the. piston, the operation being similar to that of the four cycle engil'ie, with the. r-xception that the exhaust port is lo* i'aed at the crank shaft end of the cylinder instead of at the opposite end thereof.
When the device is to operate as a two cycle engine it is merely necessary to hook up the rod 35 which may be accomplished by moving the cam lever 41, and thls may be done by afoot lever or yhand lever ar- 'ranged within' convenient rreach of the engineer. Thisn'rf/i/ves the -valve to open osition and the, Operation thereafter wil be similar to that of atwo cycle engine. When the rod 35 i,s .moved/up, it is preferably moved adis/tance/suificient to place it 'beond the reach ofthe lever y43, so that' the atter will run idle.-
`Provision is also made/for changing the spark when the type/ of engine is altered. '-lclaimzl 1. In an internal combustion engine, a cylinder, a crank casing, 'a transfer port for conveying an explosive charge from the4 crank casing to the cylinder, a rocker valve arranged inv said port, a half time shaft, a
valve actuating means operable from said shaft and serving to move the valve to open position once during each two revolutions of the crank shaft, and means for disconnecti ing the operating mechanism and locking j said valve in open position to permit operag tion as a'two cycle engine.
2. In an internal combustion engine, la c linder, a crank case, a piston, a crank 30 I s aft connected to the piston, an inlet port in communication with the crank case, a transfer port within the crank case of the cylinder, an exhaust port leading from the cylinder, a rocker valve'. mounted in the' transfer port and controlling the same, a rocker arr'n connected to the valve, a half i time shaft geared to the crank shaft, a disk Acarried by the half time shaft and provided i W-ith'a crank pin, a lever @arranged to be en- 40 gaged and operated by the crank pin, a rod connected to the rocker arm and arranged to be engaged by said lever to move the valv to open position once'during each two revolutions of the crank shaft, a spyigfornio ing the valve to closed position, an'dnans Y for locking the rod out `of contact witlntlw g lover and holding the valve'inppen position.
ln testimony that l claim the foregoing :is my own, I have hereto allixed my signatur(l 50 in the presence of two witnesses.
