IMPROVEMENT IN STEAM-CYLINDER LUBRICATORS.

Specification forming part of Letters Patent No. 208,931, dated October 15, 1878; application filed April 2, 1878.

To all whom it may concern Be it known that I, NICHOLAS SEIBERT, of

San Francisco, in the State of California, have invented a new and Improved Method of Feeding a Lubricant to Steam-Cylinders; and I hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, making a part of this specification, which represents a perspective view of the devices to carry out my method of feeding the 1ubri cant.

The object of my invention is to provide a means of regularly feeding a lubricant to the cylinders and other parts of a steam-engine; and it consists in utilizing, through suitable devices, the impulse of the pump injector or inspirator at each pulsation to throw a given quantity of oil, to be regulated by suitable cocks, into the steam-chest to lubricate the valves and piston.

In order that thoseskilled in the art may make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the said drawing, A represents a steamboiler provided with the usual steam-dome B and steam-pipe C, conveying the steam to the steanrchest 1) over the cylinder E.

The usual pump or other water-supplying device F is connected to the water-space of the boiler by pipe (1, provided with the checkvalve to. Between the pump and check-valve a, I tap pipe to and insert a pipe, bythe other end of which enters the bottom of acup or tank, G, containing oil or other lubricant. On pipe 0, between pipe at and the oil cup, I locate a check-valve, d, a stop-valve, c, and between them an air-chamber, f.

Passing from-the top of the oil-cup into the steam-pipe, above its juncture with the steanr chest, is an oil-supply pipe, 71, provided with a check-valve, 2', and a regulation feed-valve, I. The bottom of theoil-cup is supplied with a cook or waste-valve, I, to withdraw the water when all the oil is out of the cup, and a suitable removable cap is constructed on the top of the cup, which allows the introduction of a new supply of oil.

The operation is as follows: The oil-tank is filled with oil. WVhen the pump injector or inspirator is put in motion to feed the boiler with water, the water will be forced into pipe b, and the check-valve awill hold it, and at the same time the air in chamber f is compressed by the water. Then open valves 0 and I, and the pressure from chamber f will force a portion of the water into tankG, and the same amount of oil out of the oil-tank through pipe h, and into thesteam-pipe, where it is sprayed, and enters the valve-chest and cylinder commingled with the steam. The steampressure through pipe h'being at an equilibrium, the pressure stored in air-chamber f, by means of the back-pressure in pipe a, caused by the weight of check-valve a, or by the momentum of water being forced into pipe (0 by injector or inspirator, will overcome that equilibrium in favor of pipe h, and force the oil through pipe h against the pressure of steam into steam-pipe 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The improved method of feeding lubricants to steam-cylinders, consisting in feeding the lubricant through the means of the pulsation of the water-feeding device forthe boiler.

2. Boiler A, cylinder E, steam-chest 1), pump F, and feed-pipe a, in combination with oil-tank G, pipe I), provided with valves 0 (I and air-chamber f, and pipe h, provided with valves 5 Z, all constructed and operated substantially as set forth.

NICHOLAS SEIBERT.
