can be placed in a well of small diameter or small dimensions. Another advantage is that there are no loose parts. Consequently, the pumps can be used for great lengths of time without pulling the pumps. Another advantage is that the packing cups are not so exposed as to be worn by the sand or gravel. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. Reference is had to the accompanying drawings which form a part of this application.
Fig. 1 is a side elevation pf the improved pump, partly broken and partly in section.
Fig. 2 is a vertical section of the well casing and other parts.
Fig. 3 is a horizontal section, taken on the dine 3-3 of Fig. 2.

Fi 5 is a detail view of the supply tank for t e pumps.
Similar characters of reference are used to indicate the same parts throughout the several views.
This invention includes a power cylinder 1 and a pumping cylinder 2. A piston 3 is operated in the power cylinder and a piston 4 is operated in the pumping cylinderand both are operated by a common piston rod. 5. The piston rod 5 operates through a block 6 and packing 7 is provided for the piston rod 5. The pump cylinder 2 has two discharge pipes. When the piston 4 moves upwardly, the water is discharged through a pipe 8. When the piston 4 moves downwardly, the water is discharged through a pipe 9. The
.2 b a joint 10. The
the piston 4 is moving downwardly. A check ton 3 or to fill the space below the piston 3 in pressure through said pipes 8 and 9 are connected above the cylinder ipe 8 is provided with a c eck valve ll'whic 1s open when the iston 4 is moving upwardly, and closed w en valve 12 is provided for the pipe 9 and this valve is closed when the piston 4 is moving upwardly and open when the piston 4 is moving downwardly so that water will be forced out of the cylinder 4 through the pipe 9.
The piston 4 is opera-ted through the head 6 by the piston 3. The piston 3 is operated by a fluid which is forced down through a pipe 13. This gives the upward motion of the piston 3. The fluid for forcing the piston 3 downwardly is supplied through a pipe 14 which delivers the fluid in the cylinder 1 above the piston 3.
The intake of water or other fluid to be pumped consists of a port 15 through the block 6 which is opened by a valve 16 when the piston 4 is making an upstroke. Another intake for the fluid to be pumped is a port 17 in the head 18 of the cylinder. This port is closed by a valve 19 when the piston 4 is making the upstroke and open when the piston 4 is making the down stroke so that the liquid will come through the port 17 and fill the space above the piston 4.
The fluid for operating the piston 3 is operated or forced into the cylinder 1 by pistons 20 operating in cylinders 21. The cubical contents of each cylinder 21 must be suflicient to fill the space in the cylinder 1 above the piscylinder 1. The pistons 20 are provided with piston rods 23 and 24 which are to be operated by any suitable pump jacks. Any vacancy in the cylinders 21 is filled automatically by power fluid from a tank 22.
What I claim is,
1. A hydraulic pump comprising a head, a power cylinder connected to said head and provided with pumping mechanism-including a piston, a head, a pump cylinder olf-set relative to said head and provided with a piston and intake and exhaust ports, a'common piston rod for said pistons operating through said head, and means for supplying fluid head to said power cylinder alternately above and below the piston therein including supply pipes operating through said heads, cylinders and pistons in said cylinders for driving fluid pressure through said pipes, one of said cylinders being adapted to contain suflicient fluid to fill the space in said power cylinder above its piston and the other cylinder being adapted to contain enough fluid pressure to fill the space below said power piston. c
2. A hydraulic pump comprisinga head, a power cylinder connected to said head and provided with a pumping mechanism including a piston, a pump cylinder off-set relative to said power cylinder and connected to said head and provided with a piston. a common piston rod for said pistons operating through said head, means for supplying fluid pressure above and below the piston for said power cylinder including an overhead tank for compressed fluid, cylinders connected thereto and provided with pistons in said cylinders, supply pipes connected to said cylinders and projected through said head, and means for maintaining a supply of fluid pressure in said power cylinder through said head.
In testimony whereof, I set my hand, this 27th day of April, 1928.
