Description: |
| Abstract:
The apparatus as heretofore and now generally employed for lubricating the cylinders of steam-engines consists of a cup to contain the liquid lubricating matter which is connected by a pipe and stopcock with the inside of the cylinder, so that the engineer, by turning the handle of the stop-cock, can at any time permit any desired quantity of lubricating matter to run into the cylinder; but as this is required to be done by the engineer, the duty is often neglected or imperfectly attended to and always involves great waste of the lubricating material. The object of my said invention is to render the lubricator automatic and also adjustable, so that when set the required quantity of lubricating matter will be introduced into the cylinder at each stroke of the piston, and the quantity so introduced at each stroke of the piston can be adjusted to the exact quantity required; and my said invention also consists in combining, with the means for automatically supplying the cylinder with lubricating matter, a means by which the steam acts automatically on the fat or other material to be used as a lubricator, and keep it in a fluid state while the engine is in action.
Claim:
The lifting-puppet or equivalent valve in valve-tube open at the lower end, in combination with the oil-cup and with the tube or passage, the open end of which opens into that part of the valve-tube which is above the valve, and the other end communicates with the cylinder of the engine when the apparatus is attached thereto substantially as specified, by means of which combination, when a vacuum is induced in the cylinder, the valve-tube above the valve is exhausted and the valve lifted by atmospheric pressure, and the lubricating matter forced from the cup into the cylinder of the engine. |
