APPLICATION FILED APILZO, 1910.
Patented Jan. 6, 1914.
\WYQ my WITNESSES HIS- ATTORNEY IN FACT inure sraras ra WEB MARK IB. CRIST, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO THE COLONIAL TRUST COMPANY, TRUSTEE, OF PITTSBURGH, PENNSYL- VANIA, CORPORATION OF PENNSYLVANIA.
I EXPLOSION-MOTOR.
To all whom it may concern:
Be it known that 1, MARK B. Carer, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Explosion- Motors, of which the following is a spec fication.
This invention relates to the general class of explosion motors and particularly to that class in which the explosion charge consists of air and gas.
As is Well known, gases of different B. T. U. values require difierent proportions of air to effect proper combustion. For example, the proportions of producer gas to air is generally about 1 to 1 while the proportions of natural gas to air is about 1 to 13. The proportioning of air and gas for the combustion fuel may be provided by arranging different port cuttings in a piston admission valve whose ports communicate with the air and gas inlets, and the proper proportions will be maintained so long as the value ofthe gas remains constant. If however, as might easily be the case Where producer gas was used, the B. T. U. value of the gas falls ofi', the relative proportions of airand gas entering the combustion chamber would be destroyed because as the gas becomes poorer the percentage of air to gas should be decreased and as the gas becomes richer again the relative proportion of air to gas should be increased.
I have provided means for maintaining the ignition fuel mixture in proper proportions of air and gas irrespective of variations in the quality of the gas during the operation of theengine, so that should the gas decrease in quality, a greater proportion of gas may be admitted as part of the mixture than would be admitted when the gas wasrich. Instead of throttling the gas the air may be throttled, ,or if desirable, the air and gas could be throttled simultaneously; that is, more air admitted at the same time that less gas was. admitted or vice versa.
In the drawings I have shown a crosssectional view through a gas engine cylinder equipped with a mixing valve constructed in accordance with my invention and a throttling regulator as shown in vertical Specification of Letters Patent.
Application filed April 20, 1910.
Serial No. 556,463.
section as applied to the gas inlet pipe, which carries one of the mixture contents.
By referring to the drawings by numerals of reference, gydesig'oates a gas engine cylinder provide with the usual exhaust valve 2. The cylinder is shown as being provided with an inlet port 3 having a mixing valve comprising a casing 4 provided with gas ports 5 and air ports 6. Within the casing 4c is a reciprocatory piston or trunk valve 7 having gas and a-ir ports designated by thereferenae numerals 5 and 6 respectively and adapted to register with the gas and air ports in the casing, 4:. The valve 7 is carried by the stem 8 of a mushroom valve 9 which normally closes port 3 but the move- .ment of which is synchronous avith that of the valve 7. The valve stem 8 carries a head or disk 10 which is spring pressed so as to normally keep the valve 9 closed and consequently the valve 7 closed. The valves 7 and 9 are intermittently moved in opening directions by a rocking lever 11 shown as fulcrumed at 12 and. actuated by rod 13 from some suitable shaftin a well known manner. On the shaft 8'is shown an arm 14 adapted to be connected to a governor or speed responsive device whereby a change in load will rotate the valve 7 about the valve stem 8 and throttle the charge. When the lever 11 is caused to effect an inward movement of the valves 7 and 9 the ports 5 and 6 are opened and the ,proper quantity of air and gas will be admitted to the combustion chamber, and ifthe quality of the gas is such as to be proper for the port cuttings 5 and 5 the proper proportions of air and gas will be admitted but should the quality of the gas fall oii orincrease, the port cuttings 5' and 5 would not provide proper proportions of air and gas for the best combustion. I
I have provided means for overcoming the objection just enumerated and an embodiment of the device illustrated consists of a butterfly valve 15 in the supply pipe 16. A link 1.7 connected to said valve 15 is also connected to a link 18 which in'turn is connected to a lever 19 fulcrumed at 20 on a bracket 21 on the stationary element 22 of a pressure regulator illustrated as a gasometer. The stationary element or tank 22 of the pressure regulator is in communica- Patented J an. 6, 191a.
'tion with the pipe 16 through a pipe 23 so that the pressure within. the movable element or hell Qel of the gasomcter will he deperuilcnt upon the pressure in the pipe 16. The movable member or hell 2% of the gasometer is connected to the lever 19 by link so any n'iovcmcnt of the lever 19 which will impart movement to the link 18 will likewise impart movement to the link and therefore move the bell 2 An adjusting mechanism is provided for the g LS ometcr which illustrated as comprising a spring 26 connccloi'l to the lever l 9 on the side of the fulcrum 20 opposite to that on which the links and?) are. 1c spring 2G is connected to a l ln'czidcd pin passing through an in'tcruallv threaded ai'ljusting \vhecl ltl carried by the ln'aclict 29 on the gasometcr taulr 22, thus the gasmuetcr cell 24 inav he loaded to suit any measure.

posing for example that port cuttings oi the adsn on valve were provided for producer gas, that is, the proportions of: air and gas entering the combustion clnnnhcr were about 1 to l. Under normal conditions, that is, so long, as the remains constant in i3. 'l. U. value, the relative proportions of air and gas entering the combustion chamher during constant load would remain the same. Should the gas fall oil however in B. T. U. aluc the engino'would slow down, the speed responsive device would open the valve 7 and there would he a pressure drop in. the pipe 16 so that the hell 24 would drop against the action of the spring 26, and the valve 155 would he opened to permit a greater flow through the pipe '16. As the rate of flow (on account of the increase in pressure) would he i tn'rcased through the por l 53 and 5 it isohvimis that more gas would he admitlcd'lz'i proportion to the air. Should the 'l. U. value of the gas increase the pressure in. the hall 24; would increase and the hell would he rai ed to throttle lhe poi'l; through the nnnliuin ol' the valve 15; and the pressure in the pipe 16 would he cut down, therefore the proportion of gas lo air would be decreased as; the rale of flow of the gas would he decreased on account oi? the rcdiwtiouot pressure in the pipe up,
From the foregoing it will be obvious that the pressure regulator in connection with a valve of different port cutting will providethe proper proportions of air,and irrespcctivc of the change in B. 'l. U. value of l our the gas and the proper adjustment for any predetermined pressure maybe manually made through the medium of the adjusting Wheel 28.
Having thus described my invention, What I claim is: v
1. In a gas engine the combination with a valve having air and gas inlet ports, means for varying the port areas, air and gas conduits leading to said ports, a valve in one of said conduits, and a pressure regulator responsive to pressure due to the changes in the port areas of sai first mentioned alvc for operating said second mentioned valve 2. in a gas engine, a valve having (new ently proportioned air and gas ports, air and conduits leading to said air and gas ports. means for varying the size of the port areas, and pressure regulated means for varying the pressure in one of said conduits responsive to pressure due to changes in the port areas.
3. In an internal combustion engine, a valve having air and gas ports, conduits leading to said air -and gas ports, means for varying the port areas, a pressure regulator in communication with one of said conin one of said conduits, a pressure regulator in communication with one of said conduits and responsive to pressure due to changes in the port area of the port with which it communicates, means for connecting said pressure regulator to said valve, and means for adjusting said pressure regulutor to operate under predetermined pres sure, said pressure being determined to acconnnodatc a. gas of a known value' in testimony whereof, I have hereunto subscribed my name this 18th day of April,
