PATENT GFFICE.
THOMAS OROBKE, OF PITTSBURG, PENNSYLVANIA.
IMPROVEMENT IN SIPHON STEAM-PUMPS.
Specification forming part of Letters Patent No. 117,450, dated July 25, 1871.
.To all whom t may concern:
Be it known that I, THOMAS ORORKE, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Siphon Steam-Pump; and I do hereby declare that the following is a full, clear, and exact description thereof, referencebein g had to the accompanying' drawing and to the letters of reference marked thereon.
The nature of my invention consists in a siphon steam-pump having a detachable and adjustable tube arranged in it around the steam-pipe and concentric to it, and extending forward and backward of the outlet of steam.
To enable others skilled in the art to make and use my invention, I will proceed to describe more fully its construction and operation. 0
In the accompanying drawing which forms part of my specification, Figure 1 is a vertical and longitudinal section of my improvement in siphon steam-pump. Fig. 2 is a transverse section of thevsame at line y of Fig. l.
A represents the casing or shell of the pump, in the chamber B of which is a steam-pipe, C. The shell A is provided with three openings, D e j', which are furnished with screw-threads for the purpose of attaching the several pipes, viz., the steam-pipe at D, the water-supply pipe at e, and the pipe used for conveying water from the pump at f. The shell A and pipe Cv are cast in one piece, the pipe C being formed in the core which forms the chamber B of the shell A, which process of cast-ing is well understood by the skillful molder. Around the steam-pipe C, concentric to it and the outlet of the chamber B, is arranged a tube, h, which extends forward and aft 1oFf the outlet of the steam-pipe C, as shown in The operation of my improvement is as follows: Steam owing into the pipe C and out into chamber B will cause the water to flow into chamber B through the pipe attached at c, and the forward iiow of steam from the pipe C will cause the water to flow out from chamber B through the opening f, dividing the outflowing current into two parts, one part of it iiowing through the tube h and the other part through the space a' between the shell and tube. By arranging the tube around the steam-pipe in the manner hereinbefore described the pump will act more efficiently and with a less pressure of steam than it will without the tube h, and the flow of water from the pump will be steady and regular, which is not the case with the ordinary steam-pump known as siphon steam-pump. By having the tube h adjustable the pump can be .adapted to fluids of different specific gravity and for lifting' them at diji'erent elevations, which is a great consideration in a siphon steam-pump.
It Will be observed that when the tube h is removed from the shell A the pump will be of the ordinary construction; therefore, I desire it to be clearly understood that the main feature of my invention consists in the use of the tube h with relation to the steam-pipe C and the outlet of the chamber B.
Having thus described the nature, construction, and operation of my improvement, what I claim as of, my invention is- A siphon steam-pump having a detachable and adjustable tube around the steam-pipe C extending forward and aft of its outlet, and arranged concentric to it and the outlet of the chamber B, substantially as herein described and for the purpose set forth.
