PATENT' OFFICE, I
HUGH COLL, OF MILLVALE, PENNSYLVANIA.
IMPROVEMENT IN WATER-EJECTORS.
Specification forming part of Letters Patent No. 143,884, dated October 21, 18T-3; application-filed August 22, 1873.
To all whom it may concern:
Be it known `that I, HUGH COLL, of Millvale borough, in the county of Allegheny and State of Pennsylvania, have invented a new andusefulImprovement in Water-Ejectors, and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing formfectly regular cylindrical shape in cross-sec-l tion, as shown in Fig. 2. The forward end of the discharge-chamber is drawn down to form a nozzle, which corresponds in shape to that shown in the patent granted to me December 20, 1870. The receiving-chamber a is separated from the discharge-chamber b by means of a diaphragm, c, which extends across the lower portion of the shell A. This diaphragm is provided with an opening, c, at the rear end of the receiving-chamber, whereby the latter communicates withthe discharge chamber. The diaphragm, together with the upper portion of the shell d, forms a perfect circle. (See Fig. 2.) The injection or steam pipe f enters at the rear end of the shell A, as usual, and projects a short distance beyond the opening between thc receiving and discharge-chambers. At its forward end the discharge-chamber is drawn down to form a nozzle, 7i, the outer end of which is threaded intern ally to form a socket, h', for the discharge-tube.
The operation of this pump is thc same as that of its class. The jet of steam driving out the air, 85e., om the discharge-chamber b, creates a partial vacuum, and thereby elevates the water Vthrough the induction-tube, which is attached to the socket 7c, whence it passes into the receiving-chamber a, thence through the opening e into the discharge-chamber, and out through the nozzle.
By my improvement I amenabled to reduce the amount of material that is necessary in the construction of this class of siphon-pumps, and by forming the whole shell in one piece by casting I very much simplify the manufacture, and at the same time strengthen the shell. "By forming the receiving-chamber outside of the discharge-chamber, so as not to alter the symmetry of the discharge-chamber, I am enabled to preserve one of the features of the doubleheaded siphon-pump--that is, to reduce to a minimum the friction in the discharge-chamber. It is evident that if there were any irregularities in the curve of the outlines of the discharge-chamber a corresponding amount of friction would be produced. This, of course,
is objectionable.
I have found that it is not necessary for the purpose for which the double-headed pump was made that the receiving-chamber formed between the inner and outer heads should eX- tend entirely around; hence I make this receiving-chamber on the lower side only, while v the diaphragm acts as a break-water to destroy the force of the inilowing current and prevent it from coming directly in contact with the jet of steam. Thus I secure all the advantages of the double-headed pump, and at the same time save a large portion of the material which has heretofore been necessary in making the inner head, and simplify the construction of the pump.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A siphon-pump in which the receivingchamber is formed by means of a diaphragm extending extending across the lower portion of the shell, such diaphragm forming part of the shell and having an opening, e, at the rear of the steam-nozzle, whereby the water is admitted into the discharge-chamber, substantially as described.
2. The shell d, castin one piece, of a regular spherical form, in cross-section, having a diaphragm, o, which, with the upper portion of the shell, forms a circular discharge-chamber, b, of smaller diameter, the receiving-chamber a being the lower or eccentric portion of the shell, substantially as described.
Intestimony whereof I, the said HUGH COLL, have hereunto set my hand.
