Specification of Letters Patent.
Application le. February -1, 1907. Serial 3o. 355,229.
To all whom it 'may concern.-
' Be it known that I, FRANK A. SHAnrNEcK,
citizen of the United States, residing at Chicago',.in the county of Cook and State of Illinois, have invented neil7 and useful Improvef ments in Gas-Engines, of which the following is la specification.
rIfhis invention relates to internal combustion engines, and has for its object to increase the power vof the engine by increasing 'the compression pressure at the' time of explosion. This is done by means of a supplemental or reserve compression chamber in which high or explosion pressure is maintained during the oper-ation of the engine.
In the accompanying drawings, the inven tion is illustrated in connection with a Afour c cle engine, Figure 1 being a lvertical section throughthe cylinder and said chamber.
Fig. 2 is a sectional elevation illustrating mechanism for throwing the device constituting the invention 1n or out of action.v
Referring s ecifically to the drawings, 1 indicates. the cy inder casting and 2 the reserve or auxiliary compression chamber. These are connected by the usual combustion or compression chamber 1a and a puppet valve at 4. lThe compression chamber has a relief valve 3 which may be set at any desiredpressure. The valve 4 is operated by a stem 4J* having around the same a coiled spring 15 which normally clotses the valve.
The piston is indicated at 11, the main connecting rod at 5, the crank shaft at 6, vthe small gear of the two-to-one gearing at '7 and the large gear at 8, the latter being carried` upon a way shaft 16 which also carries a cam 9 which operates the valve stem 4a. Said stem is guided by a bracket il). The engine is of course provided with the usual inlet and exhaust valves, not shown.
The cam 9 is splined upon a way shaft 16, as indicated at 17, and is movable baclr and forth onsaid shaft, to. be thrown in or out of operation, b ayoke 18 .connected by a rod 1 to a han lever 20, the latch 21 of which en 'ages in a. segment 22.
ssuming that the cam 9 is thrown into action under the valve -stem 4a, the operation is as follows: As the piston starts down on thesuction stroke the va or isdrawn in through'theusual intake va ve, and as the piston starts back the intake valve closes and the charge is compressed in the usual manner.4 When the crank has nearly reached i the centerl the cam 9 lifts ythe valve 4, allowforced out by the up stroke of the piston.'
Successive revolutions cause a re etition of the operation described, and it wil be understood that with each successive revolution the pressure in the tank 2is raised until the limit is reached at which point the relief valve 3, previously set at any required pressure, opens and allows the excess to escape. inasmuch as the valve i opens just before the ignition the compression of the chargeis increased from the ordinary compression pressure to substantially the explosion pressure, thereby creating greater force when the charge is exploded. The effect is to cause an exceedingly high compression pressure, before the explosion.
For the purpose of cutting the device out of' action and thereby allowing the engine to pick up quickly without having toy run .until a high pressure is accumulated in the auxiliary chamber, the device as shown in Fig. 2 may be operated. Thus, when the lever is thrown back as .shown in the drawing the cam 9 is pulled out from under the valve stein Lia and so does not operate, but it is thrown into operation by moving the lever forward to the last notch.

v trolling the connection, a Way shaft hav-ing two-to-.one gearing to the crank shaft, a cam on the way shaft, andv means operated by the cam to open the valve, the cam being shaped to open the.. same during the ending of the compression period and the beginning ofthe expansion eriod.
4. Ina our 4cycle engine, in combination,
, a cylinder, a pressure storage chamber 'connected thereto, a normally closed 'valve controlling the connection, a Way shaft having two-to-cne gearing to the crank shaft, a cam on the way shaft, and means operated bythe I compression period and the beginning of theI expansion period, and to allow the same to rernain closed during the remainder of said periods, and meansto govern the action of y the cam.
5. Iman internal combustion engine, in combination, a cylinderhaving a pressure storage chamber connected thereto, means to trap in said chamber exploded gases under pressure from the cylinder at the time of anexplosion and retain the same during successivestrokes of the engine, and means to admit said trapped com ressed gases to the cylinder just'prior to t sion.
