Description:
Abstract:

This invention relates to devices for delivering lubricating-oil to the pistons and other enclosed parts of explosive-engines. Heretofore such devices have generally been so constructed and arranged that it has been impossible to determine with certainty whether the lubricating-oil is being properly fed. Even when sight-glasses are provided it has often happened that the oil-passages, including the passage through the sight-glass, have been filled with oil, so that the escape of oil from the needle or other valve drop by drop cannot be seen.

It is the object of this invention to provide such a construction so that the accumulation of oil is prevented and the dropping of the oil from the needle or other valve can be seen at all times.

A further object is to render the feeding of the oil dependent upon the action of the engine alone.

Claims:

l. The combination with an explosive-engine having a chamber in which a partial vacuum is produced by the rearward movement of the piston, of an oil-receptacle, a conductor to deliver oil from said receptacle to a port in the cylinder-wall, said receptacle being below said port and said conductor terminating in said receptacle below the surface of the oil, and a vent from said port to said chamber whereby the flow of oil is induced by the partial vacuum in said chamber, substantially as shown and described.

2. The combination with an explosive-engine having a chamber in which a partial vacuum is produced by the rearward movement of the piston, of an oil-receptacle, a conductor to deliver oil from said receptacle to a port in the cylinder-wall, said receptacle being below said port, and said conductor terminating in said receptacle below the surface of the oil, a check-valve in said conductor, and a vent from said port to said chamber whereby the flow of oil is induced by the partial vacuum in said chamber, substantially as shown and described.

The combination with an explosive-engine having a chamber in which a partial vacuum is produced by the rearward movement of the piston, and a passage from said chamber to the working cylinder through a port adapted to be covered by the piston, of an oil-receptacle, a conductor to deliver oil from said receptacle to an oil-port in the cylinder wall, said receptacle being below said port and said conductor terminating in said receptacle below the surface of the oil, and the vent from said oil-port to the passage between the chamber and the air-port, substantially as shown and described.

4. The combination of an explosive-engine having a chamber in which a partial vacuum is produced by the rearward movement of the piston, a pitman and a trunk-piston with an oil-opening there through, of an oil-receptacle, a conductor to deliver oil from said receptacle to an oil-port in the cylinder-wall, said receptacle being below said port and said conductor terminating in said receptacle below the surface of the oil, said port being in line with said oil-opening in the piston, and a vent from said oil-port to said chamber whereby the flow of oil is induced by the partial vacuum in said chamber, substantially as shown and described.

5. The combination with an explosive-engine having a chamber in which a partial vacuum is produced by the rearward movement of the piston, of an oil-receptacle, a conductor to deliver oil from said receptacle to a port in the cylinder-wall, said receptacle being below said port, and said conductor terminating in said receptacle below the surface of the oil, a sight-glass in said conductor, and a vent from said port to said chamber whereby the low of oil is induced by the partial vacuum in said chamber, substantially as shown and described.

6.The combination with an explosive-engine having a chamber in which a partial Vacuum is produced by the rearward movement of the piston and a passage from said chamber to the working cylinder through an airport adapted to be covered by the piston, of an oil-receptacle, a conductor to deliver oil from said receptacle to an oil-port in the cylinder-wall, said receptacle being below said port, and said conductor terminating in said receptacle below the surface of the oil, a sight-glass in said conductor, and avent from said oil-port to the passage between said chamber and the air-port whereby the flow of oil is induced by the partial vacuum in said chamber, substantially as shown and described.

7. The combination with an explosive-engine, of a receptacle for lubricating-oil disposed below the top of the cylinder and open to the atmosphere, a sight-feed above the cylinder, and connections between said receptacle, sight-feed and cylinder, whereby the oil is drawn from the receptacle under atmospheric pressure by the movements of the engine and the feed of the oil is stopped when the engine is stopped.
