I QMMIQVQOU- UNITE STATES PATENT OFFICE.
EMILY E. TASSEY, OF MOKEESPORT, PENNSYLVANIA.
SIPHON PROPELLER-PUMP.
SPECIFICATION formingpart of Letters Patent No. 280,723, dated August 3, 1880.
Application filed June 27, 1879.
To all whom it may concern Be it known that I, EMILY E. TASSEY, of the borough of McKeesport, county of Allegheny, State of Pennsylvania, have invented anew Siphon Propeller-Pump and I do hereby declare the following specification and drawings are sufficient to enable any person skilled in the art to which it appertains to make and use my said invention.
The object of my invention is to provide means for discharging large quantities of water-as from a coffer-dam or dry-dock-into the river.
It consists of a curved tube and draft-tube with regulating-valves, communicating with a propeller-pump or other mechanical device for raising water, which combination preserves and utilizes the velocity of the water in the pump by permitting it to discharge in an ascendin g and widening curved siphon-tube, and then descend in a draft tube containing a greater area of water than the suction-pipe. The'water being permitted to ascend and then fall by natural gravity added to' the impulse of the pump, it fills the place of the longer arm of a natural siphon and becomes a powerful aid in raising the water in the suction-' pipe.
As the higher head of a siphon gives greater velocity, so the velocity of the water in the pump represents the higher head.
The height to which the curved tube may ascend must vary according to the conditions in which it is placed; but no advantage can be gained by carrying it higher than thirty ieet, the height to which water is sustained by atmospheric pressure.
Referring to the drawings, Figure 1 is a plan or downward view of the dry-dock, steam-engine, centrifugal pump, and curved tube. Fig. 2 is the. section indicated on Fig. 1 by the dotted line y y. Fig. 3 is the section indicated on Fig.1 by the dotted line mm. Fig. 2 shows the suction-pipe. Fig. 3 shows the draft-tube at right angles to the former.
Similar letters indicate in each of the figures like parts.
S is the steam-engine or other power employed to rotate the centrifugal pump A by means of the shaft B. L L-are the spiral pro-- peller-blades, filling and working in the conical casing. O is the suction-pipe. D is the draft-tube, and G is the ascending widening curved siphon-tube, both of which tubes are air-tight.
H represents a jet of compressed air or steam as is used in the steam siphon-pump. K and F are valves to allow the escape of the air in priming, and also to be opened if the draft becomes too strong when the dock is nearly emptied. 4
The draft-tube D is made larger than the suction-pipe, to avoid friction, and also because the increased area has greater power of suction. I
The conical casing is open throughout, ex-
cept the shaft and propeller-blades, to allow free course for the water and avoid friction.
Without the rotary pump, and used as what is commonly called a steam siphon-pump, a jet of steam may be introduced into the curved tube, as at H, Fig. 3, the valve E being open to permit its free course until the pump is primed and the draft begins, when it should be closed. The steam condenses in the draft-tube and, creating vacuum, becomes again a power in lifting the water in the suc tion-pipe.
The same combination being used and applied to a boat or ship, the draft-tube may descend within the ship and terminate in the bottom, a valve being used to prevent the entrance of the external water.
I claim 1 1. A water-elevator having an ascending siphon discharge-tube the area of which increases outwardly, and provided with regulating-valves, substantially as set forth.
A water-elevator having an ascending siphon discharge-tube, in combination with a draft-tube of greater area than the suction, as and for the purpose set forth.
3. A water-elevator having an ascending siphon discharge-tube the area of which increases outward, in combination with a drafttube, substantially as described.
4. A water-elevator having an ascending siphon discharge-tube the area of which increases outward, and provided with regulating-valves, in combination with a draft-tube, substantially as set forth.
5. The combination. with an ascending siphon discharge-tube provided with a suitable priming-valve, of a steam-jet, substantially as described, and for the purpose set forth.
EMILY E. TASSEY.
