WILLIAM J. GRIFFITH, Ol" FLINT, MICHIGAN.
GASENGINE Specification of Letters Patent.
Patented Jane e, 1908.
Application led June 3,' 1907. Serial No. 376,936.
To all whom. it 'ma/y .concern/f Be it known that I, WILLIAM J. GRIFFITH, a citizen of'the United States, residing at Flint, county of Genesee, State of Michigan, have invented a certain new, and useful Im- )rovement in Gas-Engines, and declare the iollowing to be aiull, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanyingv drawings, which form a partof this speciiication.
My invention relates to gas engines, and the object of my improvements is to provide an improved gas engine employing the two cycle mode of operation.
In the accompanying drawings z-,Figure 1 is a sectional elevation of an engineiembodying my invention. Fig. 2, is a plan view in section, the section being taken on the line 2-2 Fig. 1 Fig. 3, is an elevation of the entire engine with carbureter attached. The exhaust pipe is omitted. Fig. 4, is a plan View of the piston. Fig. 5, is a vertical diametral section of the piston.A Fig. 6, is a section on the line 6 6 Fig. 2, showing the exhaust pipe and a cock therein.
3 is the cylinder, and 4 is the piston recip- ,rocating therein.
14 is 4the crank shaft, 12 the crank, 11 the connecting rod, 13 the crank case, and 16 the fly wheel upon the shaft 14.
5'is a cylinder located below the crank vcase `13, and 6 is a piston reciprocating therein.
. as indicated at 8a, and .then extending npward 'and communicating with a passage through the piston 4, to which piston it, said connecting rod, is also rigidly secured.
7 Yis anintake valve to the cylinder 5.
9 is a puppet-valve controlling the opening from the bore of the piston rod 8 to the cylinder 3 above the piston 4.
10 is a sparking lug secured in the piston 4,I the point-being ibcated at the top bf, and near t e surface offsaidpiston. The wire from thev sparking plug 10 passes partly around the lower. face of the piston 4,y to which it is secured; it is then wound into a helix 17, and then passes out through the wall of the crank case.
15, Fig. 3, is the carbureter connected by a pipe to the intake 7 to the cylinder 5.
18 is the exhaust passage.-
B is the exhaust pipe, andal a cock in said pipe by which the exhaust passage may be opened and closed.
The operation of the above described engine is as followsz-W'hen the piston 4 rises, it carries with it the piston 6, drawing an oxplosive mixture into the cylinder-5. 'hen the piston 4 returns downward, the mixture is compressed in the cylinder 5 below the piston 6, and is forced through the hollow rod 8 into the space above the piston 4. Upon the Lip-stroke of the piston 4, the mixture above it is compressed, and the mixture is lighted at the upper end of the stroke by a spark from the wire of the plug '10. The piston then descends under the impulse of the explosion and exhausts vin the usual way through the assage 18. The mixture which has now een compressed below the piston 6; lifts the valve 9 and ilows into the space in the cylinder 3 above the piston 4, displacing the rest of the products ol combustion. The just described operation is then again repeated.
vThe coil or. helix 17 allows the piston 4 to reciprocate without disconnectingthe wire to the pluglO. I believe that I secure advantages and morev power by igniting the m'ixture'adjacent t0 the piston as shown.
It will be observed that by this arrangement the necessity of compression vin the crank case is avoided, and as much or as little mixture may be compressed as is desired.
To reverse the engine, I manipulate the cock A so as to close the exhaust passage. The engine is now checked by the work of accumulating compressed air in the cylinder 3 above the piston 4, and by shifting the lightingmechanism so that the spark shall take place on the 'up-stroke the engine may A be reversed.
Thgre 1s always an explosive mixture 1n the cylinder 3, so that the engine may be 'started by y a spark.
IVhat I claim is 1. The combination of a power cylinder, a power piston therein, a pump. cylinder and pump piston therein, a hollow piston rod common to sald plstons and commumcatlng of said pistons and opening through said pistons, ya puppet `valve located on the power;
piston to control the opening from said piston rod, an exhaust apparatus ada ted to relieve" the pressure of explosion atft e end ofthe power stroke, substantially as and for the purpose described. V p
3. In a'two cycle'gas engine having a iston therein,. a pump cylinder located b e owl said engine, a piston in said cylinder having a' hollow piston rod extending therefrom and adjacent to a wall of said gas engine, said piston having the off-set 8a therein and eX- tending'- through and secured to the piston of the gas engine, forthe purpose described.
4. In'a two cycle gas engine having a cylinder and a piston therein, a pump cylinder having a piston therein, means for connecting said pistons together, a assage extending between said cylinders t rough thev means for connecting said pistons together., and means for controlling said passage, for the purpose described.
In testimony whereof, I sign this specification in the presence of two witnesses.
