STARTING ATTACHMENT FOR EXPLOSlVE-ENGINES.
SPECIFICATION forming part of Lettersl Patent No. r266,116, dated July 26, 1904.
Application filed February 24,1903. Serial No. 144,612. ING model To tl whom, t may concern:
ranged to be acted upon by cani l2, secured Be it known that we, HARRY M. RAwL, of y to the inner end of a shaft 13, extending' New Brighton, and DEMisEY L. REEHL, of
Vest Bridgewater, in the county oT' Beaver i is secured to the tube or casing Q.
through and journaled in the bearing I-L, which Shaft 13 and State of Pennsylvania, have invented a is provided with an operating-handle 15. In
new and useful Starting' Attachment for Explosive-Engines, of which the following' is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whichg Figure I is a top plan view of our improved attachment. Fig. 2 is a sectional side elevation of the same, and Eig. 3 is an end elevation of a gas-engine provided with our attachment.
Our invention relates to the starting oT' gasengines by the use of compressed air or compressed air and gasolene or any other hydrocarbon combined, and is designed to provide a simple and easily-operated attachment which may be cheaply made, easily repaired, and may be operated by a single lever.
In the drawings, 2 represents a supply tube or conduit, one end of which is connected to the gas-engine cylinder, while the other end is connected to an air-reservoir. This tube 2 is provided at each end with an inwardlyseating' valve 3, arranged to close against a removable seat AI, having a central tube exi.
tension 5 surrounding the stein 6 of the valve. The valve is thus guided in its movements and is normally held to its seat by a spiral spring 7, surrounding' the inner portion of the valvestem and compressed between an end collar or enlargement 8 of the stein and the inner end of the guide-collar 5.
To provide a simple and cheap arrangement of the parts and to make them easy ot' access for repairs, we preferably enlarge the tube near each end to provide an annular shoulder 9, against which the ring forming the valve-seat fits and is held by a connection l0, screwed into the end of the tube and preferably provided with stops l1, which limit the opening' movement of the valve.
The inner ends of the valve-stems are arl l l i i l i l l i the top of the tube or conduit is provided a hole in which is screwed a cup 16, provided with a valve-handle I7.
The attachment is preferably provided with a small air-cock I8, leading' from the interior portion of the tube or conduit between the valves. The air-tank 19 is preferably provided witli a pressure-gage 20 and also with a sealing-valve 2l in the pipe 22, leadingI to the double-valve attachment. The attachnient may be connected to the gas-engine cylinder 23 by screwing the connection l0 into a port leading through its Side, as shown in Eig'. 3, or in any other convenient manner.
In usingl the device the handle l5 of the attachment is turned so as to close both of the valves 3. A small quantity of gasolene or other hydrocarbon is poured into the cup 16. The cock 18 is opened to release any pressure in the attachment and then closed and the valve IT opened to drop the gasoleneinto the supply-tube before connection is established between the air-tank and the cylinder. The sealing-valve in the pipe leading from the airtank is then opened. A throw of the starting-valve handle admits a sinall quantity of air to the cylinder, vaporizing the gasolene in the pipe and forming a combustible mixture which is ignited in the cylinder, thus giving the piston its movement. On its next forward stroke the piston draws in a charge from the regular supply, the handle l5 having been moved to allow the valve to close which leads into the cylinder.
The air-tank will supply air for several stai'tings, and to reiill the air-tank it is only necessary to cut ofi' the gas-supply, openthe sealing-valve, and raise the starting-valve handle. The power stored in the fly-wheels is suticient to recharge the air-tank ready for further starting of the engine, or any form ot an air-compressor may be used to charge the air-tank, either operated directly from the engine or by power from any outside source.
rlhe advantages of the invention result from the use of the single handle having connections Which actuate both of the valves, one controlling the connection to the air-tank and the other-that tothe cylinder. A movement in one direction of the handle actuates one valve, and an opposite movement forces open the other valve. A simple, compact, and inexpensive device is thus provided.
Variations may be made in the form and arrangement of the parts Without departing from our invention.
We claiml. A starting device for explosive-engines. a tube or conduit having an intermediate inlet for combustible material, and valves on opposite sides of the inlet, one valve being arranged to connect to the air-tank andthe other to the cylinder, and asingle lever arranged to force open either valve when desired; substantially as described.
2. In a starting device for explosive-engines, a tube having inwardly-seating valves on opposite sides of its center, springs arranged to keep the valves closed, said tube having an intermediate inlet for combustible fuel, and an intermediate shaft independent of the engine having a cam device arranged to force open either valve; substantially as described.
3. In a starting device for gas-engines, a tube having removable valve-seats in opposite ends thereof, screw connections arranged to hold the seats in place, said tube having an intermediate inlet for combustible material, inwardly-seating valves, springs arranged to hold the valves to their seats, and a shaft between the inner ends of the valve-stems having a cam arranged to force open either valve; substantially as described.
4. In a starting device for explosive-engines, a tube or conduit having valved outlets at its end, and an intermediate valved inlet for combustible material, said tube having an intermediate valved air-vent, and means for opening and closing the valve for combustible material; substantially as described.
In testimony whereof We have hereunto set our hands.
