GAS-ENGINE STARTER.
SPECIFICATION forming part of Letters Patent No. 787,341, dated April 11, 1905.
Application filed October 29,1903. Serial N0.179,075.
Be it known that we, REUBEX A. MrrennLL and lncs'rnn L. Lewis, citizens of the United States, residing at ()il City, in the county of Yenango and State of Pennsylvania, have invented certain new and useful Improvements in Gas-Engine Starters: and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in gas-engitie-starting apparatus, and particularly to means for controlling the admission of pressure from a source of supply to an engine-cylinder.
The object in view is the provision of means for supplying a number of successive charges to a gas-engine cylinder controlled by a single valve.
\Yith this and further obj ects in view thein v veution consists in certain novel construetions. combinations, and arrangements of parts, as will be hereinafter fully described and claimed.
ln the accompanying drawing the figure represents a longitudinal vertical central section through a mechanism embodying the features of the present invention, parts being illustrated in elevation.
in the present art it is common to start a gas-engine by extrinsic mechanical power, and it has been proposed to impart the initial stroke to the piston of a gas-engine bysupplying an expansive charge to the piston-head:
but in practice we find that a single stroke of cates any suitable gas-engine cylinder provided with a piston 2. A tube 3 discharges into the explosion end of the cylinder 1, and an ordinary hand-operated plug-valve -'i is interposed in the length of tube 3 for control ling the admission of pressure therethrtnigh. An exlntust-valve 5 is also interposed in the length of the tube 5, and the casing of said valve is provided with an exhaust-port 6, adapted to be thrown into conununication with the bore of pipe I; by means of the passage T, formed in said valve 5, and such communication being established when the valve is rotated to the position indicated in dotted lines. A central passage 8 is formed in valve 5 for normally establishing communication between the sections of pipe 3. The section of pipe 3 beyond the valve 5 communicates with the valve-casing t), which casing is also in communication with tubes 10, 11, and 12, communicating with receptacles or tanks 13, 14, and 15, respectively. A valve 16 is rotatably mounted within the casing 9 and is pro vided with a central straight passage 17 and side passages l8 18, whereby the pipes 10, 1], and 1.2 may be successively thrown into communication with pipe 3 by rotation of the valve 16.
The receptacles or tanks 13, 1 t, and in practice are supplied with air or other gas under pressure and are provided with suitable heating means of any preferred type. \Ye have illustrated as a means for rapidly heating the said receptacles a central tube It) in each of the tanks extending longitudinally thereof and surrounding a gas-supply pipe 20, apertured, as at 21, and leading to a common gas-supply pipe 22.
In operation after the tanks 13, H, and 15 have been charged with a supply of compressed air say under a pressure of one hundred poundstbe cut-oil valve 13 in feed-pipe 13 is closed, thereby sealing said tanks 13 H; 15, after which the gas is turned on through pipe 22, and the gas discharged through the burners formed of pipes 20 is ignited for heating the tubes 19' and the air within the surrounding receptacles. The
heat may be regulated as desired; but we prefer to raise the tenmerature ol the contained atmosphere suthciently tor increasing the pressure approximately seven times, whereby a charge passing from one of the tanks into the cylinder 1 will be effective in throwing the piston 2. When the desired pressure is secured within the tanks 13, 14, and 15, the valves 5 and 9 being in the position indicated in the drawing, the valve 4 is opened and the air within the tank 13, expanding, passes out through tube 10, upper passage 18, and tube 3 into the cylinder 1, throwing the piston 2, and as soon as the said piston reaches the limit of its receding movement the valve 5 is moved to the position indicated in dotted lines, whereupon the charge within the cylinder 1 is exhausted and the piston 2 permitted to return to its former position. As soon as the piston 2 has reached the limit of its return stroke the valve 5 is rotated to its former position, as indicated in full lines in the drawing, and the'valve 9 is rotated for bringing the passage 17 into register with pipes 11 and 3, and a second charge is thus admitted to the cylinder 1, which throws the piston, as above described, and the charge may be exhausted in a similar manner to the exhausting of the first charge, whereupon the valve 9 is rotated for bringing the lower passage 18 in position-for establishing communication between pipes 3 and 12, and a third charge thus admitted to the cylinder 1.
With the high degree of pressure which we secure with our tanks it may not be necessary each time the engine is started to utilize all of the charges, and, in fact, a single charge may be sufficient for successfully starting the gas-engine; but with the arrangement of the elements disclosed it will be seen that a failure to start the engine is hardly possible.
It is obvious that when a charge has been shot from one of the tanks 13 14 15 to the engine-cylinder the pressure in such tank is substantially exhausted, owing to the relatively small size of said tanks compared with the capacity of the engine-cylinder. The device illustrated in the drawing is meant to be operative in such manner that only a single shot or charge of compressed and heated air from a tank may be available. We do not intend that a tank as either of the three illustrated in the drawing may be used for a succession of charges or shots to the enginecylinder without recharging and reheating the compressed air in the tank, but prefer that the tanks be charged after each shot, so that full advantage may be given by reason of the great increase in pressure owing to the rise-of temperature of the compressed air in the tank.
It will be seen by reference to the drawing that we have provided means for heating the atmosphere within the tanks 13, 14, and 15, and such heating means is so arranged as to readily produce an excessively high temperature or superheated condition of the contained its pressure multiplied to a maximum degree. The burners 20 are so arranged within the respective tanks 13, 14, and 15 that the heat produced thereby is diffused approximately evenly throughout the respective tanks, and the contained air has all of its parts substantially simultaneously heated, whereby a maximum amount of pressure may be obtained in a minimum time. The heated compressed air is admitted to the explosive-engine oylin der, as above set forth, and while we have illustrated and described the employment of a plurality of tanks we find that by the su perheating of the air sufficient pressure may be obtained for imparting suflicient force to the piston in the cylinder for effectually starting the engine by a single discharge from one of the tanks.
