OTTO NELSON, OF CHICAGO, ILLIN e it known th zen of the United cago, in the coun n 01s, ASSXGNOB OF ONE-FOURTH TO DAN'IEL I. TETE AND ONE-FOURTH T0 PETER LIGNELL, BOTH OF CHICAGO, ILLINGIS.
GAS ENGINE.
Application led March 16, 1921. Serial No. 452,677.
I, Or'ro NnLsoN, a citi- States,
ty of Cook andState of lh-nois, have invented certain new and useful Improvements the following is a My invention r has for one of its simple' and eflicie engines.
in Gas Engines, of which specification.
elates to gas engines and objects the provision of a nt timing means for gas A further object is the provision of means for drawing a full charge to a point adjav cent the working of said cyhnden cylinder by means outside sti-ll further object is the provision of a simple and eiiicient mea-ns fonopening and closing the ports of a relations with eac Other objects w An embodiment of -tra-ted in the accom ing a part of t whichgas engine in definite h other. ill appear hereinafter.
my invention is illuspanying drawings, formhis specification, and in Fig. 1 is a vertical section taken through an engine embodying Fig. 2 is a sect Fig. 1; and
Fig. 3 vis a looking from line eferring more ings, l have indic mounted on a cra working piston 7 der.
Mounted crank shaft 8 ani nected to the piston These parts may b my invention; ion taken on line 2-2 of fragmental section taken as 3`3 in Fig. 2.
particularly to the draw ated a working cylinder 5 nk` casing G and having a mounted in said cylinin the crank case is a..
.l the crank shaft is con- 7 by a connecting-link 9. e of ordinary construction.
The upper part of the cylinder 5 may be provided with a.
These cylinders may be provided with a water jacket which may be a continuation of water jacket. 10, or
cooled in any other desirable manner. cylinders 12 and 13 may be 'The formed with removable tubes 14 which provides their inner surface or bores tubes 14 may be when so desired, or the dispensed with and their residingat Chi-L inner walls formed in any desirable manner. e provision of the tubes 14 provides a simple and easy manner for making the ports. The port 15 `which communicates be tween the cylinder 5 and cylinders 12 and 13 preferably extends entirely around the tubes 14, as clearly indicated in F ig. 2, and said tubes are each provided with a plurality of ports 16 which are arranged entirely around said tubes. This provides means whereby the Huid passing from intake cylinder 12 into lcylinder' may pass out through the ports 16 entirely around its tube 14 and the fluid passing from cylinder 5 into cylinder 13 can pass through all of the ports 16 into its tube 14:. I prefer to have the combined areas of openings 16 in each of the tubes lit substantially equal or slightly greater than the cross area of said tube. This relation, however, may be changed in accordance with any desired construction. llhe arrangement of the ports 16 entirely around the tubes 14 also facilitates cooling the adjacent parts of the cylinder walls.
Slidably mounted in cylinders 12and 13 are plungers 17 and 18. The plungers 17 and 18 and piston 7 are each provided with the usual packing rings 19. A connecting rod 2O connects each of plungers 17 and 18 with:a crank or cam shaft 21, and the latter is connected by gears 22 and 23 with crank shaft 8 in a relation so that, the crank shaft 8 makes two revolutions to one revolution of the crankishaft 21'. The plungers 17 and 18, connecting rods 20, and the cranks of crank shaft 21 are arranged so/as to properly time the engine. I preferably arrange the cranks on crank shaft 21 at substantially'() i'lcgrees apart. The axis 24 ot' the connection between plunger 17 and its connecting rod 2O is* substantially directly over the axis of crank shaft 21 so that the intake port ofthe engine may be arranged to remain open during the downward movement or suction stroke of the piston y7. The axis 25 of the connection between plunger 18 and its connecting rod 20 is preferably arranged to one side of a ,vertical line passing through the axis of shaft 21 so that the exhaust port of the engine will be opened a longer time than the inta-ke port and near the end of the l speed, it is desired the engine to run, the farther apart these lines `are, the taeter the time or' the engine Will'be.
In the arrangement of the vparts as herein shown, the plunger 18 is in a position where it begins-to uncover openings 16 in the. sleeve 14 of the exhaust valve cylinder in Fig. 1'. It will be noted that the piston 7 is not quite to the end of its working stroke,l
as indicated b the osition of crank shaft .8 and a. direction in fleeting arrow 26. The
' ""rcachcs e point 28 and then the intake POND v arrangement is such that during the continued movement of crank shaft 8 around through its bottom deed center, end to its top dead center the crank shaft 21 will move from the position shown to a point 27 when the plunger 18 will be brought heck to the position shown in Fig., 1. 'lhis will permit the exhaust valve to be opened somewhat more Ithan one stroke of piston 7. The length of plunger 17 and its particuier relation to the crank shaft 21 will cause it to beginv opening the intakeport when its crank will remain open While its crunk is pessing from point 28 to point 27, and during this movement the crank 8 will be moved from its upper deed center to its lower dead center.
With the arrangement justset forth it will be apparent that the intake plunger 17 wiil move from its position indicated in Fig.. 1 down to e position where it begins to uncover ports 16 before the iston 7 begins to drew uelinto the cylin er 5. ,This pro vides drawing fuel from the cerbureter to e positionvery close to the port 15 ready to be taken up by the suction of piston 7 in ycylinder 5 es soon. es the'inteke port isopen. .This constructionf, then provides means for bringing e charge of fuel to the cylinder ready to hete-ken up .by the' letter as soon es the intake port is open. The conical top portions of the plungers 17 end 18 will help to direct the' fuel into the intake ports and inenten to directthe dimherge gases from the 'exhaust ports to the center of the cylinder 13 4end then up out through exhaust pipe 29.
and out of elnement with the axis of auxiliary crank shaft.
In en en ine of the character described having an ex enst cylinder andan intake cylinder, e plun Jerfor seid intake cylinder,
y plunger for seid exhaust cylinder, e crnk mit, e connecting rod connected to said ihteke plunger et e point adjacent the periphery thereof, and e connectingir'od connected with seid exhaust plunger'fat a. point cidjacent the periphery thereosaid connccting rods each having its 4lower end oonnccted with seid crank shaft, whereby the connecting rod for seid intake cylinder joins enid'inteke plunger at e point above thel axis of. seid crank, end the connecting rod for seid exhaust cylinder joins seid exhaust plunger et 'e point out of elinement with seid crenk she-ft. c
ln testimony whereof l have signed my neme to this specification on this 14th day of Merch, A. D. 1921.
