Specification of Letters Patent.
Patented Aug. 22, 1911.
Application filed June 17, 1910. Serial No. 567,369.
To all whom it may concern:
Be it knownthat I, WALTER \V. WELLS, a citizen-of the United States, and a resident of Clyde, in the county of Sandusky and State of Ohio, have invented a new and Improved Explosive-Engine, of which the following is a full, clear, and exact description.
The invention is an improvement in multiplecylinder explosive engines, particularly engines in which the cylinders are arranged in pairs and are cooperath 'e with each other in the introduction of scavenging air preparatory to the admission of the explosive .charge.
The invention has in view an engine of this character of simple constructlon', in which the working pistons pcrtormthc offices 0f separately compressing the air and explosive mixture and controlling their ad mission to the explosion chamber without supplementary cylinders and pistons or va ves for this purpose, each cylinder of the engine having an explosion chamber and an air compression chamber in which the single piston works, and each explosion chamber having separate inlets for the air and for the explosive mixture, and a separate ex haust outlet, with the inlets arranged to be uncovered by the piston in successive order, and with the air compression chamber of each cylinder connecting with the air inlet of the other cylinder, and the crank case of each cylinder connecting with the explosive mixture inlet of the same cylindeln.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of wt erence indicate corresponding parts in all the views.
Figure 1 is a central vertical section through one of the cylinders of an explosion engine constructed in accordance with my invention, the piston being shown in the position for the exhaust and admission of the explosive charge; Fig. 2 is a side view of the upper portion of the engine, with the port case for the scavenging air removed; Fig. 3 is a section on the line 3--3 of Fig. 4; and Fig. 4: is a section on the line 4. -4 of Fig. a
For the purpose of illustrating the preferred character of my invention I have shown an engine of the two-cycle type having the cylinders 5, 5, arranged one in ad:
vance of the other. each cylinder having the 'ablv applied customary crank case 6, and having an explosion chamber 7 and an air compression chamber 8, the air compression chamber being arranged ad acent to the crank case and reatively larger in diameter than the explosioifcliambcr, thus forming what is com-. monly known as a ditlercntial area cylinder.
\Vithin each cylinder is a working differential area piston 9, fitting within the two chambers, the pistons of the two cylinders being connected to the cranks 10 in the usual manner, as by pitmen 11, which cranks are arranged in the respective crank cases and reversely positioned, the crank of one cylinder being at an angle of 180 to the crank of the other cylinder.
Connecting with the enlarged ortion of the cylinder or air compression 0 iamber, is an air inlet 12 and a gas inlet 13, the latter being arranged below the former and ordinarily leading from the carburetor, with the air inlet arrangedto be uncovered atthe terminus of the down stroke of the piston, and the gas inlet uncovered only upon the completion of the up stroke of the piston, thus alternately placing these inlets in respective communication with the air compression chamber 8 and crank case 6. The explosion chamber 7 is provided with the usual exhaust port 14, and the admission or inlet port 15, for the explosive charge, this port, as is the general practice, connecting with the crank case through a passage l6,
extending between the Walls of the cylinder. The explosive chamber is also provided with an air inlet port 17, which is arranged to be uncovered by the piston in its down or working stroke immediately before the uncovering of the inlet 15, the latter being in full communication with the explosion chamber when the iston has reached the limit of its down stro to, this being also true of the exhaust port 14. which is uncovered by the piston at or about the same time as the ai admission port 1.7. The air compression chamber 8 of each cylinder communicates with the air admission inlet 17 of the oppo site cylinder, for which purpose each air compression cylinder discharges at a point at or near the top, into a passage 18, between two branches of the passage 16, within the walls of the cylinder, the iassage 1.8 connecting with one of the ports 19 of a port case 20, leading to the air inlet 17 of the other cylinder. The port case 20 is removto the projecting port souls of a y, h
19 extend from the lower portion of the casa,
at one side to the upper portion of the case at the opposite side and intersect at the center of the case,
With the engine thus constructed, toward the end of the down or working stroke of one of the pistons, the air admission p0rt17 of the cylinder in which the piston is Working 1s uncovered, allowing the air which has been compressed in the air compression chamber at the other cylinder to rush into the exiiosion chamber and sweep the burned gases out through the exhaust. Immediately after this takes place the inlet for the explosive charge is uncovered and the explosive mixture which hasbeen compressed in the crank case of the same cylinder is admitted into the explosion chamber. Atxthis period otthe piston action, the air inlet 12 is uncovered, which allows the air at atmospheric pressure to freely pass into the air compression chamber 8. 0n theup or return stroke of the same piston, the charge is compressed in the'usual way, and the air admitted to the air compression chamber compressed, and released into the explosion chamber of the other cylinder just before the piston of this cylinder completes its Working stroke. In this manner each explosion chamber of the engine is thoroughly clarified in alternate order after each cornplete cycle.
Having thus described my invention, I claim as new and desire to secure by Letters Patent: i 1. In an explosive engine, the combination of two cylinders, each cylinder having an explosion chamber and an air compression chamber, a crank case in connection with each cylinder, a piston in each cylinder working in both its chambers, each explosion chamber having separate inlets for, air
