Specification of Letters Patent.
Patented Nov. 14:, 1905.
Application filed April 18, 1905. Serial No. 255,406.
To all whom, it may concern:
Be it known that I, PAUL HANSEN, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Outlet-Controllers for Filters; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to controllers adapted to be used in connection with filters or any other devices where it is desirable to maintain a constant flow.
The main object of my invention is to provide a controller having a minimum number of moving parts simple in construction and suitable to operate under varying conditions.
To these ends my invention comprises, generally stated, a suitable-shell or casing having an inlet and outlet, an inner shell, a piston arranged within said inner shell, a valve connected to said piston controlling the inlet, means for admitting the water to both sides of said piston, the overflow from said inner shell to said outer shell being above said piston.
My invention further comprises the novel features hereinafter set forth and claimed.
To enable others skilled in the art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a vertical sectional view of my improved controller. Fig. 2 is a sectional view of the casing. Fig. 3 shows details of the valve; Fig. 4, details of the valve-bushing, and Fig. 5 is a view of the yoke forming the bearing for the stem for controlling the movements of the piston.
Like numerals indicate like parts in each of the figures.
In the drawings the numeral 2 designates a suitable shell or casing composed of a single casting having the inlet 3 and the outlet 4. This casing 2 is further provided with the diaphragm 6, which forms the annular passage for the water to direct the same up into the controller. The casing 2 is provided with a plate 7, which closes the opening 8 in the bottom of said casing, and said plate is secured in place by the screws 9. A pipe-top 9 is formed in the plate 7, to which a pipe may be secured for flushlng the valve-chamber when By removing this plate access may desired.
be had to the valve-chamber for the purpose of repairing or of cleaning the same.
\Vithin the casing 2 is the inner shell or casing 10, which is secured to the outer casing 2 by means of the screws 11. This inner casing 10 has the collar 12, with the openings 13 formed therein. Vithin the collar 12 is the bushing 14, having the openings 15, which register with the openings 13. A valve 16 is adapted to iit within the bushing 14, said valve having the ports 17, which are adapted to be broughtinto coincidence with the openings 13 and 15 of thecollar 12 and the bushing 14. Connected to said valve 16 is the rod 18, the upper end of said rod beingconnccted to the piston 19. This piston 19 is composed of the ring 20 and the disk 21, and said disk is provided with the small openings 22. The piston 19 lits within the piston-chamber 23, said chamber having the cross-piece 24 secured by the bolts 25 to the flange 26 on said piston-chamber. In order to support said piston-chamber, a stem 27 has the threaded end 28, which engages with a threaded seat in the cross-piece 24, said stem passing up through the yoke 29, secured by the bolts 30 to the flange 31 of the inner shell 10. Said stem forms a swivel connection 32 with the yoke 29 and finally passes up through the stuiiing-box 33 on the top 34 of the shell 2. Secured within the pistonchamber 23 is the perforated plate 35, from which extends the adjustable valve 36, with the openings 37 leading into the annular space 38 between the piston-chamber 23 and the inner shell 10. The lower end of the valve 36 enters the bushing 14 and is adapted to be raised or lowered therein as occasion may require. From the above it is apparent that by turning the stem 21 the pistonchamber 23 may be lowered, and with it the valve 36, moving within the bushing 14, whereby the size of the opening 37 may be reduced.
\Vhen my improved controller is in use in connection, for instance, with a lilter, the in let 3 of the shell 2 is connected up with the pipe leading from the outlet of the filter, while the outlet 4 of the shell 2 is connected with the suymly-pipe. The water entering the inlet 3 enters the chamber 38 and passes therefrom through the openings 13 and 15 and the opening 17 of the valve 16 up through the opening 17 into the annular space 38, surrounding the piston-chamber 23, to the inner shell 10. The water also passes up through the perforated plate 35 into the piston-chamber. The water rises in the space 38 until it overflows into the piston-chamber above the piston. As the water still continues to rise it passes over the top of the inner shell 10 in the form of a weir and passes down through the annular space &0 between the inner and outer shells to the outlet 4. Owing to the weir being higher than the piston-chamber, a back pressure is always maintained on the upper side of the piston. In case the pressure of the water entering the controller is increased so as to overbalance the piston, tending to push it upward, thereby increasing the head over the orifice, the valve 16 will be closed, or partially so, so as to reduce the amount of water entering the controller. If, on the other hand, should the pressure or head on the piston not be suflicient to maintain the weight, it drops, thereby opening the valve and allowing more water to enter. In this manner an even supply of water is maintained automatically and without the use of floats or piston-controllers operated in connection with butterliy-valves.
The rate of flow through the controller can be varied by raising or lowering the pistonchamber by turning the stem 27 and reducing the size of the opening 37. By means of the openings 22 in the piston any air carried up against the under side of said piston is permitted to escape.
l/Vhat I claim is 1.
