Description
H. A. DUC, JR., 0F CHARLESTON, SOUTH cARoLINA. Leners Patent No. sasoadaad Janna/ry 12, 1869'.
IMIPROVEMENT IN CENTRIIUG-AL PUMPS.
The Schedule refen'ed to in these Letters Patent and making part of the same.
To all whom 'it ma/y concern:
Beit known that I, H.- A. DUC, Jr., of Charleston, in the district of Charleston, and State of South Carolina, have invented a new and improved Centrifugal Pump; and Ido hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, Areference being had to the accompanying drawings,
forming part of this specification.
Figure 1 represents a vertical sectional view of my improved `centrifugal pump, taken on the plane offthe line x-x, iig. 2.
Figure 2 is a vertical section of the same, taken on the plane of the liney y, fig. 1.
Similar letters of reference indicate corresponding parts.
My invention consists in the arrangement of a gate across the annular chamber of a centrifugal pump, by means of which said pump may he formed without the employment of a foot-valve.
A, in the drawing, represents the annular ease or shell vof a centrifugal pump, made of suitable material, and of suitable size.
B is the eduction-ppe, through which the liquid is discharged. l Y
E is the induction-pipe.
G is the-wheel, mounted on a horizontal shaft, D,
that passes centrally through the oase, as indicated in fi 2.
The wheel consists of one solid head, a, of an annular head, b, and of a series of buckets, c c, securedbe? tween the heads in the ordinary or in suitable manner..
formed behind each bucket, which will canse the air to v rushout between the buckets into the induction-pipe E. F represents an oscillating or sliding gate, iitted acrossthe annular channel that is formed between the wheel and the outer' side of the case, said gate preventing the water from beingv carried around with and lby the wheel, and from thus circulating in the case.
If the water should be allowed to circulate, the vacuum formed behind each bucket wpuld not be so large as to allow the rapid discharge of the air, while with .the gate the vacuum is enlarged and the discharge facilitated.
The gate should be -oscillating, or sliding, or otherwise so arranged that it can be taken out of the way, so as to admit the passage of obstructions that may enter the pump.- Y
This pump need not be primed before it is set in motion, as it will commence discharging as soon as the water enters the case i'n which the Wheel revolves.
I claim as new, and desire to secure by Letters Patentl A gate, arranged across the annular' chamber of a centrifugal pump, by which it is primed, without theA employment of a foot-valve, substantially as set forth.
