IMPROVEMENT IN CONDENSERS FOR ENGINES.
Specification forming part of Letters Patent No. 193,589, dated July 31, 1877 application filed February 12, 1877.
To all whom it may concern Be it known that I, WILLIAM JOHN ALLEN, of Bnfi'alo, in the county of Erie and State of New York, have made certain Improvements in Condensers for Engines, &c., of which the following is a specification:
This invention is intended for engines and vacuum-pans, the object being to get a better vacuum than is now obtained by siphon or other condensers, and which I accomplish by using a fall of water through small pipes leading from the condenser-head into the individual air-pipes, causing a greater flow of air, and, consequently, greater suction of the air above the point where the air and Water meet, all as hereinafter fully explained.
In the drawings, Figure l is a front elevation with the condenser in half-section. Fig. 2 is a side elevation of the same, showing the bent or curved water-pipes, and their connection with the air-pipes.
A represents the condenser-head; B, the induction steam-pipe leading from the engine or vacuum-pan, and G the induction water pipe or joint to the condenser, which will be supplied with water from a tank above, or situated in any suitable place. (1 act are the air-pipes, down which the air from the condenser-head passes. b b b are short (or long) water-pipes, their tops of uneven height inside the condenser, to get a greater or less flow of Water, according to its height in the condenser. These pipes b, outside, lead into the air-pipes a a a individually, as shown, the lower part of each being bent like a Y, or curved, as may be most convenient. This construction gives a special velocity to the water at the junction with the air-pipes at a a, and causes greater suction of air at that point and above it, giving a greater, and consequently a better, vacuum. a is the usual perforated spreading-plate.
It is obvious that if the condenser-head A be lengthened, and the pipes b b shortened, the same effect will be obtained, that being a matter of construction only.
One of the advantages of this construction is, that a less quantity of water will draw off a greater quantity of air than by any devices now used that I am acquainted with.
The operation is very simple. The force of the water through the pipes 11 b b strikes the air already in the pipes aa, forcing it down at an increased velocity, and causing a suction above in the air-pipes, which draws a greater amount of air than can be accomplished by single pipes, carrying air and Water together.
This is not a siphon-condenser, but is intended as an improvement on them.
I claim The combination of the condenser-head A, the steam-pipe B, water-tube O, air-pipes a a a, and the water-pipes b b b, the latter leading from the condenser into the air-pipes a a a, respectively, to get greater velocity of water, and greater suction of air where the air and water meet, substantially as hereinbefore described.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
W. J. ALLEN.
