HYDRAULIC RAM.
APPLICATION FILED JULY3, 1915.
WITNESSES:
A TTOR/VEY WILLIAM W. TAYLOR, OF KANSAS CITY, MISSOURI.
HYDRAULIC RAM.
Specification of Letters Patent.
Application filed July 3, 1915. Serial No. 37,980.
To allwhom it may concern:
Be it known that I, WI LIAM W. TAYLOR, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Hydraulic Rams, of which the following is a specification.
My invention relates to hydraulic pumps, and the object of the invention is to provide a simple, automatic hydraulic pump a by meansof which a constant supply of water may be taken from a spring and delivered at a higher level than the spring. Thewater so delivered may be used for irrigation and for numerous other purposes.
In order that my invention may be fully understood, reference will nowbeimade to the accompanying drawing, in which:
Figure 1 is a diagrammatic vertical sectional view of a pump embodying the invention. Fig. 2 is a detail view showingthe links in elevation and the lever in section.
1 designates a pipe which is supposed to receive water from a spring or rill.
2 designates a foundation, on which are mounted standards 3, 4 and 5.
A piston 15, slidable in the cylinder 7, has a rod 16 passing through guides 17 and 18. A crosshead 19 on piston rod 16 is connected by a link 20 with the longer arm 21 of a lever 21-22, fulcrumed on a pin 23 held by a pair of standards 4. The shorter arm22 of the lever is bifurcated at 24 to make a balanced connection with a pump piston rod 25. Said rod 25 has an eye 26 which carries a pivot pin 27, on which are a pair of links 28, connected by an upper pivot pin 29 to the bifurcated lever parts 24. An adjustable weight 31 is mounted on lever arm 22.
Mounted on standard 5 is the pumping cylinder 32 in which is a piston 33 mounted on rod 25. Also mounted on standard 5 is a small reservoir 34 having three openings .35, 36, 37 in its upper portion. A pipe 38,
connected to opening 35, leads to the cylinder 7 near the bottom thereof. .Opening 36 is an air port. An overflow pipe 39 is con- Patented July 25, 1916. i
A discharge pipe 47 rises vertically from valve chamber 45, and is connected at 48 with a horizontal service'pipe 49. This pipe 49 may be at a much higher elevation than the source pipe, 1. a
. Just below the valve seat 9 in cylinder 7, is an air relief valve 30, which opens when the piston 15 rises and closes when the piston descends.
The operation will be substantially as follows :v The stream of water that issues from the source pipe 1 will nearly fill the chamber 8, before the trip-valve 10 will be depressed, When the valve is so opened, the piston 15 will be at or near to the upper limit of its stroke, andthe water admitted thereupon from chamber 8 will cause the pistonto descend to the lower end of its stroke. This movement will actuate one upward stroke of the pumping piston 33, the relative piston strokes being of the same ratio as the lengths of lever arms 21 and 22. lVhen piston 15 passes below the port 50, water flows into pipe 38 and reservoir 34; thence past valve 42, through union 43, into cylinder 32 above piston 33, if riser pipe 47 is empty of water.
If riser pipe 47 be already full of water, however, valve 42 will not open until piston 33 starts to descend, when atmospheric pressure and the weight of the water in reservoir 34 will cause said valve 42 to open; the column of water in pipe 47 being retained by check-valve 46. The weight of the water lying upon pumping piston 33 will force said piston down by its full stroke, thereby raising the first piston 15 back to its hlghest point, as the piston 15 will have no water to lift, the valve 10 having closed immed ately after discharging the water as aforesaid.
The capacity of reservoir 34 should of course be at least equal to that of the pump cylinder 32, so that the down strokes of piston 33 will be fully performed. During the operation of the pist n 33 the at: below 112 flows into and out of the cylinder through vents 51.
Beginning with each up stroke of the pumping piston 33, (when pipe 47 contains water) check-valve 16 is opened by the piston pressure,'and the back pressure due to the weight of the water column closes the adjacent check-valve 42. Thus every up stroke of piston 33 forces a measured quantity of water into and through the pipe 47.
The pumping piston stands at its lowest position at the end of each down stroke until a charge of'water is released by trip valve 10 to start the 'first piston downward. Each charge of water may be in excess of what is required to fill the-pumping cylinder 32; the excess will flow ofi' through tube 39.
- During the up strokes of piston 15, the air compressed thereby escapes through valve 30. q
Having thus described my invention, What I claim and desire to secure by Letters Patent, is:
1. A hydraulic pump comprising apair of vertically disposed cylinders of unequal lengths, pistons in said cylinders having unequal strokes, means for actuating either pistonby reverse movement of the other piston, means for periodically dropping a charge of water upon the long-stroke piston, a water reservoir above the short-stroke piston and equal in capacity to the short cylinder, a gravity water conduit from the lower part of the long cylinder to said reservoir, a riser pipe connected with the top of the short cylinder, and suitable check-valves, all operating substantially as described.
2. A hydraulic pump comprising a pair of vertically disposed cylinders of unequal lengths, pistons in said cylinders having unequal strokes,'a lever for actuating either piston by reverse movement of theother pis- Copies of this patent may be obtained for ton, means for periodically dropping a charge of water upon the long-stroke piston, a water reservoir above the short-stroke piston andequal in capacity to the short cylinder, a gravitywater conduit from the lower part of the long cylinder to said reservoir, a riser pipe connected with the top of the short cylinder, and suitable check-valves, all operatingsubstantially as described.
3. A hydraulic pump comprising a long vertical cylinder, a long-stroke piston therein, a short vertical cylinder, a shortstroke piston therein, piston rods, a lever r operatively connecting said piston-rods, whereby either piston reversely actuates the other, the bottom of the long cylinder being higher than the top of the short cylinder, means for periodically dropping a charge of water suflicient to actuate either piston, upon the long-stroke piston, a water reservoir above the short cylinder and capable of holding said charge,a water conduit from the long cylinder to the top of said reservoir, a riser pipe connected to the top of the short cylinder, and suitable check-valves; all operating substantially as described.
4. In a hydraulic pump, a vertical cylinder, a long-stroke piston traveling therein, a chamber in the upper part of said cylinder, the bottom of said chamber having a large port therein, a pivotally mounted trip-valve adapted to seat upon and close the lower side of said port, and, yieldable means to hold said valve in closed position against a certain Weight of water.
