- J". s. HULL. V PNEUMATIC PRESSURE Puma Patented-April, 1876.
N PETERS, PHOTO-LITHOGRAPHER. WASHINGTON u c.
UNITED STATES PATENT OFFICE.
JOHN S. HULL, OF CINCINNATI, OHIO.
IMPROVEMENT .IN PNEUMATIC PRESSURE-PUMPS.
Specification forming part of Letters Patent No. 175,609, dated April 4, 1876 application filed November 12, 1875.
To all whom it may concern:
Be it known that I, JOHN S. HULL, of Gincinnati, in the county of Hamilton and State of Ohio, have invented a new and Improved Pneumatic Pressure-Pump for Drawing and Forcing Liquids; and I do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanying drawings, making part of this specification- Figure 1 being a view in elevation of theentire apparatus embodying the invention; Fig. 2, a central vertical section of the parts ot the apparatus to which my invention specially belongs.
Like letters designate correspondingparts in both figures. V
The main principle of this invention consists in the employment of the force of compressed air introduced into any close vesselwith the vessel by a pipe or passage, 0.
A cut-oft valve, a is located at the bottom of the pump, or between it and the vessel, to retain the air and relieve the pump, which may be transferred to the use of some other vessel. The liquid is drawn from the vessel through a pipe or tube, D, with a spigot, b, at
the upper end.
For conveniently connecting the pipes O andD with the vessel I employ an improved stopper or bung, E, which is made to fit an ordinary bung-hole or similar aperture in the barrel or other vessel. This bung or stopper hasa central aperture, 0, through it, in which fits the liquid-drawing pipe D, and around this is an annular aperture, d,'extending only a part of its length at the inner end, and terminating outward in a side outlet, 6, with which the air-pipe G is coupled. Thus with one bung, and without any change ot'arrangement, both the air-pump and the drawingpipe are connected with the vessel.
The liquid-drawing pipe D is adjustable up and down in the central hole of the bung, according to the height of the'liquid in the vessel beneath. Thus, if the liquid is at the height indicated in Fig. 2, the pipe D need not reach downward lower than represented 'D in the bung, while allowing an ad usting movement of the pipe, I employ a piece of cork,f, situated in a cavity in the upper part of the bung, and compressed tightly around the pipe by a'screw-plug, g, screwing down upon the cork.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A portable vessel for containing a liquid to be drawn, its upper portion forming a pneumatic pressure-chamber for forcing out and elevating the liquid, and provided with a valved inlet, through which air is introduced to produce the pressure, andwith a valve-outlet tube or pipe, through which the liquid is expelled, substantially as and for the purpose herein specified.
2. A bung or stopper, E, constructed with an air-inlet, d, and liquid-outlet c, substantially as and for the purpose herein specified.
3. The cork packing f and compressingplug g, arranged in the bung E, in combination with the drawing pipe D, substantially as and for the purpose herein specified.
Specification signed by me this 7th day of July, 1875.
' JOHN S. HULL.
