Specification of Letters Patent.
Patented June 9, 1908.
Application filed m 10,- 1007. Serial so. acacia.
a full, 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 bein had to the accompanyingdrawings, which form a part of this specification. I
Our invention relates to gas engines, and the object of our improvements is, to provide an improved and simplified engine workin on the six cycle rinciple. We accomplis this object inthe evice illustrated in the accompanying drawing, in which the view .is a vertical, central section in elevation.
A is the cylinder; B the crank case; C a piston; D the main shaft; E the connecting rod, and F the crank pin.
G is a gear wheel upon the main shaft D, meshing with a larger gear wheel H upon the cam shaft I.
. to reciprocate in guides.
N is a spring tending to force the valve stem M downward, and'the valve Lupon its seat. The cam J acts upon the roller at the lower end of the valve stem M to raise thevalve L from its seat.
'V is an exhaust assage leadin fromthe :gper end of the cy inder A, and is a valve opted to close said exhaust passage. The passage V and valve S constituting a second or auxiliaryexhaust apparatus. '1", T, is an operating mechanism by which the valve S may be raised by 0 ration of the camshown in dotted lines, an indicated by the letter K. The inlet valve to the cylinder A is of the ordin construction, and is operated in usu way.
2 is an intake valve which may be operated from the shaft I in the usual way, or in any pro er way.
e operation of the above described device is as follows :Ignition having taken place, the piston C is driven downward until lt'uncovers the port P, at which time the valve L is raised from its seat by the cam J,
and the eater part of the products of combustion is exhausted into and through the mufiler 'R. As 'the piston C rises, it covers the port P, and the valve S is now forced from its seat by the cam K, and the remaining' products of combustion are exhausted through the passage V. v The passage Vcommunicates with e outer air and not with the mufller. The )iston havin risen and discharged most 0 the remaining exhaust gases, begins again todescend, the valve S still remaining open, thus a scavenger cha e of air is drawn through the passage Having completed its downward stroke, the piston C- agam rises, thevalve S still remaining open, and discharges the scavenger charge taken in on the previous stro e. The valve S now returns to its seat, and the next downward stroke of the piston'C draws an explosive 'mixture into the cylinder A in the usual way, which mixture is com ressed when the piston C again rises. gnition new again takes place, and the cycle above described is re eated.
It will be 0 served that the'passage V serves to discharge the residual products of combustion, and to take in and discharge the scavenger charge, that there is but one valve S in the passage V, and this valve opens and closes but once in each cycle of operation.
What we claim is:
1. In a six-cyclegas engine, an exhaust apparatus adapted to relieve the pressure toward the end of the working stroke, a second exhaust apparatus adapted to convey the products of combustion remaining after the gases under ressure have been exhausted, and means or'holding said second exhaust apparatus open for the intake and discharge of the scavenger charge, for the purpose described. I
2. A six cycle gas en 'ne, 1 rovided with an exhaust apparatus a apte to be 0 ened near the end of the working stroke an with a second exhaust apparatus adapted to remain open durin the three strokes following the working stro lce.
3. In a six-cdycle gas engine, the combinascavenger ch e.
4. A six cfie gas en 51118, rovided with an exhaust ap aratus a apte to bee ened near the end 0 the working stroke am haven in said cylinder, said Sort eing so located as vex ing a conduit for the exhaust gases, a non- 15 return valve located in said conduit, said he being also provided with a second aust apparatus adapted-to remaln open during the three strokes following the work ing stroke. 20
In testimony whereof, we sign this specification in the presence of two witnesses.
