LAURITS AKSEL LAURSEN, OF HOLCOIVIBE, WISCONSIN.
HYDRAULIC PUMP.
To all whom it may concern:
Be it known that I, LAURITS AfKsEL LAUR- sEN, a citizen of the United States, residing at Holcombe, in the county of Chippewa and State of Wisconsin, have invented `certain new and useful Improvements in Hydraulic Pumps, of which the following is a specification.
This invention relates to automatic pumping apparatus and consists of a machine adapted to be used in any suitable place where a suflicient head of Water may be readily obtained to operate the pumping mechanism comprising the invention.
The invention resides particularly in the general arrangement of parts of the pumping mechanism, and the association therewith of a peculiar form of governor controlling the operation of a water supply valve which governs the passage of the water under pressure to opposite sides of a working piston, the latter being in turn connected with a pumping piston.
For a full understanding of the invention, reference is to be had to the following detail description and to the accompanying drawings, wherein p Figure 1 is a perspective view of a hydraulic pump embodying the essential features of the invention; Fig. 2 is a vertical Alongitudinal sectional view and Fig. 3 is a horizontal sectional view.
Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.
In the drawings, the numeral 1 denotes a working cylinder, the numeral 2 a pumping cylinder, and the numeral 3 a sliding valve chest. In the cylinder 1 operates a working piston 4. In the cylinder 2 operates a pumping piston 5 and a slide valve 6 is suitably mounted in the valve chest 3, and operable by a valve rod 7, passing through one end of the chest into coperation with a guide standard 8, the other end of the chest 3 having a supply pipe 9 connected therewith, and to which the water under head is supplied. Inlet ports 10, 10 and 10 in the bottom of the chest 3 permit the water to pass from the chest into the cylinder 1 on either of opposite sides of the piston 4, according to the position of the valve 6. Passages 11 and 11 are formed in a suitable casting 12 secured to the bottom of the chest 3, and said passages terminate in the exhaust port 13.
Specification of Letters Patent.
Application filed December 12, 1910.
Patented June 13, 1911. Serial No. 596,909.
The piston rod 14 of the piston 4 passes at one end through stuiiing boxes 15 into the cylinder 2 and is connected with a pumping piston 5. The other end of the piston rod 14 passes outwardly through an end ofthe cylinder 1 into a position substantially parallel with the valve rod, but in a lower horizontal plane. On said outward extension 14 of the piston rod 14 are carried spaced adjustable stops 16 arranged on opposite sides of the bifurcated end 17 of the horizontal lever 17 pivoted vbetween its ends to a bracket 18 on one end portion =of the casting 12. The opposite end of the lever 17 operates in a yoke 19 at the lower end of a vertical counterbalance lever 20 which is pivo-ted between its ends to a bracket 21 secured to the upper portion of the valve chest 3. At `its upper end the lever 2O is formed with a somewhat triangular shaped frame 22, having a transverse weight guide 23, on which is adapted to slide ya weight 24. In a manner similar to the arrangement. on the extension 14 of the rod 14, the valve rod 7 is provided with spaced stops 25, having anti-friction rollers 26 mounted thereon, the' stops `being arranged Von opposite sides -of the slotted portion 20 of the lever 20, said slotted portion being located just above the yoke 19. Spaced from the sides of the yoke 19 and arranged on opposite sides of the adjacent free end of the lever 17, said yoke is provided with longitudinal cushion rods .19 which directly engage the lever 17 in the operation of the machine.
Certain pipe connections are employed as follows: A pipe 27 leads vfrom the outer side of the valve chest 3 downwardly to a pipe 2S leading into the exhaust passages 11 near the point where said passages merge into the exhaust port 13. A valve 29 is arranged in the length of the pipe 27 and another pipe 3() leads from the two pipes 27 and 28 Vto apipe 31, one end of which is connected to the branch pipe 32 connected with the outer end of the cylinder 2. A pipe 33 leads from the point of connection of the pipes 3l and 32 downwardly and late-rally to a vertical pipe 34, and a pipe 35 extends downwardly from the pipe 33 intermediate its ends to a water delivery pipe 36, lthe latter being connected at one end with an air chamber 37. A pipe 3S is connected with opposite ends of the working cylinder 1 and a similar pipe 39 is connected with the opposite ends of the pumping cylinder 2 and suitable valve means isprovided for said pipes to permit of drawing oif sand, sediment, or other foreign matter that may collect in the cylinders 1 and 2.
Suitable check valves are provided in the vario-us pipes above referred to and in the operation of the invention, if the water is taken directly from the supply, by opening the valve 29, as the piston 5 travels outwardly or toward the member 20, the water entering the pipe 27 closes the check valve 2Sa in the pipe 28, this causing the water to pass through the pipe 30 past the valve 45, through the pipe 32 into the outer end of the cylinder 2. At the same time, water is being discharged from the opposite end of the cylinder 2 through the pipe 40, and closes the valve 41 in the pipe 31, opening and passing the valve 42 in the pipe 33 and thence entering the pipes 35 and 36 discharging Yfrom. the latter. The valve 44 closes due to the pressure of the water as it passes from the pipe 33 to the pipe 35. A full stroke of the machine has now been completed, and the pistons 4 and 5 are re` versed, whereupon the water which has pre viously entered the cylinder 2 through the pipe 32 is forced out through the pipe 32, closing the valve 45 in the pipe 37, said water passing the valve 44, closing the valve 42 and being thence discharged through the pipes 35 and 36. At the same time, the wa ter is entering the other end of the cylinder 2 through the pipes 30, 34 and 40, passing the valve 41, the valve 42 being closed as above mentioned by the pressure of the discharge water passing from the pipes 33 and 35 to the discharge pipe 36. The valve 46 is provided in a pipe extension projecting vertically from the pipe 37 and said valve 46 when opened slightly, permits the piston 5 to draw in a certain amount of air with the water, and which air will be discharged therefrom with the water, the air going to the top of the air chamber 37 affording a cushion in the chamber 37, the advantages of which will be obvious. Of course when the valve 29 is opened, the vpump wastes more water than when saidvalve is closed because the water is taken direct from the supply. 0n the other hand, if the valve 29 is closed when the exhaust water is utilized, the same passes into the pipe 28 opening the valve 28a, and thence entering the pipe 30 and passing to the cylinder 2 in the manner hereinbefore described.
Referring to Fig. 2 and describing more clearly the operation of the working piston 4, it will be understood that when said piston is in the position illustrated in Fig. 3, it is at the end of the cylinder 1, opposite to that in which it will be arranged when the parts are in the various positions shown in Fig. 2. Referring to Fig. 3, however, the water is being supplied to the left hand end of the cylinder 1 from the-valve chest 3 through the inlet port 10 and passage 11 adjacent to said port 10. This forces the piston 4 upwardly and the water in the right hand end of the cylinder 1 passes therefrom through the passage 1l, port 10, through the valve 3 and wastes through the ports 10 and 13, the latter being the exhaust. When the slide valve 3 is in the position shown in Fig. 2, the piston 4 not shown, being at its outward limit of movement, the water passes from the pipe 9 into the slide valve box or chest 3. As the slide valve does not fill more than a small portion of the chest 3,
the water passes by the sides of the valve through the port 10 and the adjacent passage 11, thereby forcing the piston 4 toward the left hand end of the cylinder 1. As the piston 4 moves toward the left hand end of the cylinder 1, the water at the left hand side of the piston passes through the left passage 11, and out of the exhaust 13 through the port 10, the hollow portion of the slide valve 3 and the port 10', the latter being just above the exhaust 13. When the slide valve 6 is reversed by the piston 4, said slide valve connects the ports 13 and 10, and the water is again forced from the supply chest- 3 through the port. 10, forcing the piston outwardly. Small yieldingly mounted plates 6 are arranged at the top of the valve 6 and are designed to relieve pressure of water on the valve so that should any water go to the top of the valve, it will reversing the valve 6 and obtaining an effective operation of the machine.
t is to be understood that the pipe 39 is a sand pipe for the cylinder 2 and equiva` lent to the pipe 38 provided for the cylinder 1.
