AIR AND GAS LOCOMOTlVE.
SPECIFICATION forming part of Letters Patent No. 401,28, dated April. 9, 1889.
Application filed December 14, 1888. Serial No. 293,569. (No model.)
To @ZZ wiz/m it may con-cern.-
Be it known that we, ALBERT SGHMID and ROBERT SIEGFRIED, citizens of Switzerland, and JOHN CHARLES BECKFELD, a citizen of the United States, all residing in Allegheny,
in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Air -and Gas Locomotives, of which the following is a specification.
lo Our invention relates especially to the construction of the class of locomotives or cars designed for streeterailway purposes and driven by engines operated by the combos tion of mingled air and I5 The object of the invention is to provide a simple and efficient form of locomotive of this character upon which a sufficient quantity of compressed air and can be carried for driving the car a required distance, and
2o for feeding the same to the combustion-cham ber in the proper proportions and communieating the power thus obtained to the drivin g wheels in a convenient and efficient manner.
It also involves the construction of suitable 2 5 apparatus for controlling the operation of the engine and the direction of movements and the application of the brakes and for illuminating and heating the oar.
In the accompanying drawings, illustrating 3o the invention, Figure l is a side elevation of the complete car equipped with the tanks containing gas and air and the combustion apparatus or generator and the engine for converting the power into motion. Fig. 2 is 3 5 a plan of the same. Fig. is an end view of the car. Fig. 4 is a transverse section of the same, and Fig. 5 is an enlarged detail of the starting-valves of the engine.
Referring to the ligures, A represents the 4o body of the vehicle; i 32 B3 B", the drivingwheels of thetruck. The truck is preferably constructed with an iron frame and provided with axle-boxes h b2 b3 b for the axles Z) b in the usual manner. The motor or engine C 4 5 operates upon a crank-shaft, C', which carries two pulleys, c c2, for communicating motion to the axles l) Z1. The motion maybe communicated through belts, or chains, or friction- A wheels, or in any other convenient manner.
5o For operating the engine, the products of the combustion of air and gas are employed. For this purpose a suitable number of tanks D are distributed about the body of the car. In this instance six tanks D are placed beneath the seats of the car, and five more are attached to the iron frame of the truck in any suitable manneiL-as, for instance, by the wrought-iron bands d. These eleven tanks all communicate with each other through suitable pipes, d. Another tank, 6o D', is also attached to the truck, and it contains gas only. The others contain air under pressure. The volumes of the air and gas tanks are so proportioned as to afford the proper rela-tive amounts for combustion when 6 5 united. The gas and air are separately conveyed into the generator or combustion-cham` ber T, being properly mingled as they enter. For this purpose they pass through a suitable mixer, D2, upon the way to the combustiou- 7o chamber. In the combustion-chamber they burn with a continuons flame under pressure, and thus fill the combristicii-chamber with the products of combustion. The pressure in the comb ustionschamber is maintained at a proper 7 5 amount-fi. c., less than the pressure in the tanks. This can be accomplished by means of automatic pressure-regulators of any wellknown type. These regulators are inserted into the pipes which feed the gas and air to 8o the combustion-chamber or generator, and a safety-valve, s, is employed on the generator for relievingit in case the pressure becomes too great. The volume obtained by the combustion is about iive times as great as the original volume. In this manner a sufficient volume is obtained for economically operating the engine. The hot gases or products of combustion are led from the combustionchamber through insulated pipes T2 to the 9o two platforms, S S2, upon either of which the driver or engineer may stand. Suitable governing-levers, E', E2, and E are placed on each platform for controlling the engine and the admission of products of combustion. The levers E serve to admit and check the flow of the products of combustion to the engine through pipes t t2. The levers E2 are respectively connected with three-way cocks e e2, which allow the hot gases from the generroo lowed to escape.
ator to enter two small cylinders, F F2, the pistons of which are connected by means of suitable rods, f, with the brake-shoes f f2. The levers serve to change the cut-off of the engine and to reverse the engine by turning the eccentric sheaves c3 through an arc of one hundred and eighty degrees in a manner well understood.
The engine itseli:` is a double-compound single-acting machine, and the connecting-rods of each pair of engines act upon the same crank, as already stated. The cranks of the two engines are set at an angle of ninety degrees to each other, so as to avoid dead-points. The two high-pressure cylinders m m2 are upon one side and the two low-pressure cylinders n n2 upon the other. In the pipes which connect the high-pressure with the lowpressure cylinders there are placed valves i; t', which, when the engine is at rest and the pipes are opened to admit the products of combustion thereto, act to automatically admit the high-pressure gases into the lowpressure cylinders, so as to start the engine in whatever position the cranks may be. These valves are constructed in the manner shown in Fig. 5. Exhaust-gases from the high-pressure cylinder enter U and pass when the apparatus is in operation through ports c into the surrounding chamber c2 and out at t3 into the low-pressure cylinder. NVh en, however, the engine is at rest, a spring, nl, forces the movable cylinder or cut-off fc5 forward, thus bringing the port 'v6 opposite an inlet, o7, which communicates with the source of high-pressure gases. These gases then passing through the inlet c7 and port t pass through an opening, fus, into the chamber U2, and thus to the escape v3, whence they pass to the low-pressure cylinder. As soon, however, as the engine is in such position that the exhaust-gases from the high-pressure cylinder may reach the inlet c, the cut-oit' is forced against the spring, closing the opening from the pipe U7, and thus shutting off the high-pressure gases from the low-pressure cylinder.
The engines are entirely covered to prevent undue radiation of heat and for protection,
' and the crank-chamber is filled with oil and wat-er. The exhaust-gases are used, if required, for heating the car, being led through suitable pipes, s', along the floor of the car.
The exhaust from the low-pressure cylinders may be carried through condensing-pipes K K upon the roof of the car and then al- For illumining the car gas is obtained from the gas-tank.
