Description

LUCIUS J. KNOWLES.
improvement in Blowing Engines.
N0 118,949. Patented Sep.12,187f.
PATENT OFFICE.
LUUIUS J. KNOWLES, OF WORCESTER, MASSACHUSETTS.
IMPROVEMENT IN BLOWING-ENGINES.
Specification forming part of Letters Patent No. 118,949, dated September 12, 1871.
To all whom it may concern:
Be it known that I, LUCIUS J. KNOWLES, of the city and county of WVor-cester and Common.- wealth of Massachusetts, have invented certain new and useful Improvements in Blowing- Engines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, which represents a central longitudinal section of the air-cylinder of a blowing-engine with my improvement applied thereto.
To enable others skilled in the art to which my invention belongs to make and use the same, I will proceed to describe it more in detail.
The nature of my invention consists: First, in the combination with the air-cylinder in a blowing-engine of an oil-passage, as and for the purpose hereinafter explained. Second, in the combination with the oil-passage of a regulating cock, as hereafter explained. Third, in the combination with the air-cylinder of an oil and cleaning-passage, and screw-stops for closingthe same,
as hereafter explained.
In the drawing, the part marked A represents the air-cylinder. B indicates the piston, and C the piston-rod, which is actuated by the driving portion of the engine; said portion being constructed and operated in the ordinary manner, it is not necessary to herein illustrate and describe it. I) indicates the induction, and E the eduction-valves and passages, which parts may be of any desired construction and form. In the lower part of the cylinder-shell I form a passage, I which is bored through from end to end of the cylinder A, and is proy'ided with orifices or openings, I 1, into the interior of the cylinder, as shown, while the extremities of the passage F at the end of the cylinder are closed by means of screw-stops K. The oil for the lubrication of the piston B is put into the interior of the cylinder A through the valve-passages or in any other convenient manner, and immediately flows to the bottom of the cylinder, filling the passage F and covering the orifices I I. When the engine is in motion the air is compressed in front of the moving pistonB while a partial vacuum is formed in rear thereof. The difference in pressure thus produced causes the oil within the cylinder A to flow through the passageF toward the end where there is the least pressure, the force being suflicient to throw a jet of oil from the orifices I against the upper side of the cylinder, thereby keeping all parts of the interior of the cylinder properly lubricated. The oil is forced up alternately at each side of the piston B as the direction of motion of the piston changes. A small cock, L, is arranged at the central part of the passage F, by means of which the flow of oil through said passage can be regulated, or the passage be entirely closed, when desired. In case the passage F becomes clogged by the use of gummy oil or otherwise, the stop-screws K can be taken out and any extraneous or viscous matter readily removed by passing a suitable instrument through the opening. In lieu of boring the passage Fin the shell of the cylinder a tube may be used having its ends connected with the orifices I, and said orifices may be arranged in any position within the cylinder, so long as the described result is produced.
Having described my improvements in blowing-engines, what I claim therein as new and of my invention, and desire to secure by Letters Patent, is-- l. The combination, with the cylinder in a blowing-engine, of an oil-passage, substantially as and for the purposes set forth.
2. The combination, with the cylinder A, of the oil-passages F I I and regulating cock L, substantially as and for the purposes set forth.
3. In the combination, with the cylinder A, provided with passages F I I, of the screw-stops K, substantially as shown and described.
