PNEUMATIC OPERATED PUMP FOR LIQUIDS.
APPLICATION TILED 00T.5, 1912.
Patented Sept. 16, 1913.
UNTTE TATE PATENT FFTCEQ HERBERT WILLIAM COPLESTONE, OF BUNBURY, WESTERN AUSTRALIA, AUSTRALIA,
ASSIGNOR OF ONE-HALF TO WILLIAM LAUNDON MARSH, OF BUNBURY, AUS- TRALIA.
PNEUMATIC-OPERATED PUMP FOR LIQUIDS.
To all whom 2'15 may concern Be it known that I, Hnnnnn'r VILLIAM CorLns'roNn, a subject of the King of Great Britain, and residing at Bunbury, W'estern Ai'istralia, Commonwealth of Aust 'alia, have invented certain new and useful Improvements in Pneumatic-Operated Pumps for Liquids, of which the following is a specification.
This invention has been principally devised for pumping or extracting kerosene, petrol or other such like penetrative or thin natured liquids and also liquids, in general, so as to avoid the wastage trouble which now occurs when liquids are being transferred from their sealed storage or transit cans or vessels. The means which Iemploy for such transference is to pump or force air into the can, so causing the uplift of the liquid; such high pressure air being the agent for the expulsion of the liquid.
In order that my invention may be clearly understood the same will be explained with the aid of the attached drawing which is a part-sectional view showing the appliance fitted to a can.
The appliance comprises an inflater barrel a in which works the piston or plunger b for forcing the air into the intermediate chamber 0, said chamber being provided with the check valve (Z to prevent any return of air into the barrel a. This chamber 0 has an extension pipe 6 whose mouth is near the bottom of the can f, and the appliance is connected to the can and held in position tightly by the spiral spring (7, while a washer 9' makes an air tight joint at such junction of the can and the appliance as shown in the drawing. The air chamber 0 communicates with the can by the bypass in which is preferably formed on the outside of the pipe 6 and serves to convey the air Specification of Letters Patent.
Application filed October 5, 1912.

Serial No. 724,184.
above the liquid, as shown by the level m-;c. The pipe 0 is continued upward and within the air chamber 2 and terminates in the spout in having the control cock at. The air is fed or forced into the chamber 0 by the inflater pump a-Z) and passes into the can f by the by-pass i as shown by the arrows and down on to the face of the liquid {II-56, thus generating the expelling force and causing the liquid to How up through the pipe 0 and out through the spout m.
lVhat I claim as my invention and desire to secure by Letters Patent is 1. An appliance of the character described comprising, in eombinatimi, a sealed, liquid container; an air pump mounted on said container and having a bypass connection therewith, for forcing air into the interior of the container above the level of the liquid therein; and an outlet pipe for the liquid connected to the bottom of said pump and extending into said container, said pipe having a discharge spout.
2. An appliance of the character described comprising, in combination, a sealed liquid container; an air pump embodying an air chamber mounted upon said container and having a by-pass connection with the interior of the same above the level of the liquid therein, a pump chamber in con'inninication with said air chamber, and a piston disposed within the pump chamber for forcing air therefrom into the air chamber; and an outlet pipe for the liquid extending into said container provided with a discharge spout.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
HERBERT WILLIAM COPLESTONE.
