WILLIAM J. SHERRIFF, 0F PITTSBURG, PENNSYLVANIA.
DOUBLE-HEADED EJECTOR.
SPECIFICATION forming part of Letters Patent No. 277,072, dated May 8, 1883.
Application filed February 15, 18 83. (ModeL) To all whom 'it may concern:
Be it known that 1, WILLIAM J. SHERRIFF, of Pittsburg, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in the Construction of Double- Headed Ejeotors; and I do hereby declare the following to be a full,- clear, and exact description of the same, reference being had to the accompanying drawings, in which--- Figure I is a longitudinal section of an ejector embodying my invention. Fig. 2 is a detached view of the steam-jet, showing its construction. Fig.3 is an end view of the steam- 'et.
Like letters refer to like parts wherever they Myinvention relates to certain new and useful improvements in double-headed steam-ejectors, and has for its object to reduce the cost of manufacture, and facilitate the fitting and finishing of the devices.
I will now proceed to describe my invention more specifically, so that others skilled in the art to which it appertains mayapply the same.
The head A B, I form in two parts. The
screw-threaded for the reception of the suctionpipe, and is provided with a screw-thread, a, for the reception of the body or combining-section B of the ejector. This section A, I preferably form by casting, and provide it with a curved steam -induction pipe, E, which is inclosed by and centered with the head, and threaded for anozzle, D.
D indicates a steam-nozzle. This nozzle is formed with a threaded shank, a, which eugages with the screw-thread a, and athreaded slotted shoulder or flange, aflfor thereception of the inner head, 0.
(1 indicates the slotsin the shoulder orflange of nozzle D to permit the passage of the water, so that the ejector may take its water not only around but through the inner head, 0.
0 indicates the inner head, which is coniform, and threaded at its base to screw upon the shoulder a of the jet.
B indicates the combining-section .of the ejector-head,which is bell-shaped at the point I), and threaded at one end,as at b, to engage with the base-section A, and at the other end to receive the discharge-pipe 0 The several parts before recited constitute the ejector, and, being united as shown in Fig. 1, will operate as follows: The steam, being admitted by the curved induction-pipe E to the head, will in escaping by jet D form a vacuum in the head A and induce the flow of wa ter. The head having filled, a limited stream will first pass to the inner head, 0, as indicated by the arrows 1, which stream, having in a measure condensed the steam and received its velocity, will induce a current through the side channels around the head,asindicated by the arrows 2, and the whole volume of fluid will then be discharged through the dischargepipe 0 4 The advantages of an ejector constructed as herein described are that the double-headed ej ector, beingin two sections, can be finished by theuseof inexpensive tools. Anydefectsin thecastings can be at once detected. The inner head and combining-section, which are parts liable to wear, can be readily replaced, and from the high finish thus attainable I have found that I can save twenty per cent. in steampress'ure, and obtain ten per cent. in the volume of water elevated and discharged, over other styles of double-head ejectors.
I am aware thatdouble-headed ejectorshave heretofore been constructed in two sections, and also that a curved centrally-arranged steam pipeor jet has been cast integrally with a nondivisible ejector-head, and do not herein claim either separately, for the reason that in the one case the increased number of parts add to the cost of manufacture and demand special skill and carein finishing and fitting up, and in the 0therviz., the non-divisible head-it is only with great difficulty that the interior can be properly finished, while by the construction herein shown and described the separate parts are reduced in number, and at the same time the whole interior of the ejector is accessible for finishing and repairing the same.
Having thus described my invention, what I claim, and desire to secure by Letters Patent,
1. In a double-headed ejector, the combination of the centrally-separable sections A B,
detachable combining-section B,having its eduction-port aligned with the induction-port a of the base-section A, substantially as and for the purpose specified.
In testimony whereof I affix my signature, in presence of two witnesses, this 7th day of February, 1883.
WILLIAM J. SHERRIFF.
