FILTER.
SPECIFICATION forming partof Letters iPatentNo. 506,304, dated October 1893.
Application filed May 26, 1893.
To all whom it may concern:
Be it known that I, JOSEPH E. BRIGHT, of St. Louis, Missouri,have made a new and useful Improvement in Filters, of which the following is a full, clear, and exact description.
The improvement relates more especially to the strainer through which the filtered water passes as it leaves the filter, and it-consists in the mode of constructing the strainer, sub-; stantially as is hereinafter set forth and, claimed, aided by the annexed drawings, mak-;
ing part of this specification, in which Figure l is a sectional elevation of a filter having the improvement; the preferred arrangement of the alum-pot is indicated in broken lines; Fig. 2 a vertical section of one of the strainers; Fig. 3 a plan of the strainers and their connections, and Fig. 4a view Show ing the parts of the strainer-chamber in vertlcal section and separated from each other.
The views are not all upon the same sca le.
The same letters of reference denote'the same parts.
A represents an ordinary filter saving as modified or supplemented by the improvement under consideration.
B represents the pipe through which wate is supplied to the filter. In the present arrangement the pipe B leads into a side'pipe O which in turn, and at the'upper end 0 thereof connects with the interior of the filter, above the filter-bed D, in the ordinary manner, and Whose lower end 0' connects with the pipe E through which the filtered water is discharged from the filter.
F and G represent valves in the side pipe G and respectively at opposite sides of the point of the connection of the pipe B therewith, and
, H represents a valve in the pipeE at the outer side of the point of the connection of the pipe 0 therewith.
I represents the waste pipe.
FAn air escape valve is shown at J and K represents a removable plugin the casing of the filter.
The alum-pot is indicated at L, and Z and Z, represent the pipes used-to connect the pot with the side pipe 0, and respectively above and beneath the position of the valve F therein, and Z Z represent valves in the pipes Z, Z, respectively. The water-pipe has a valve 'Z.
The improved strainers are shown at M.
Serial u 475.615. (No model.)
I One, two, or more of them may be used. I In the present illustration a system of four strainers is shown. They are arranged to deliver the water passing them into the pipe E. Now
my object is to provide for readily and economically constructing the strainers, and to this end the parts composing the strainerchamber are adapted to be combined and held in position by means of appliances easily obtainable. The parts referred to are shown at m, m. They are semi-spherical substantially, the lower one, m, being preferably somewhat deeper than the upper one, and they are each provided with a flange m and each of them has perforations m which taper from the interior of the chamber outwardly, all substantially as shown. To form and sustain the strainer chamber the parts m, m, are arranged as shown in Fig. 2; the flanges m m of the two parts respectively are placed together and are held between the end of the threaded tube N and the inwardly-turned flange 0 of the cap 0 which engages with and is adapted tobe screwed upward and downward on the tube N, substantially as shown. That is, the strainer-chamber, containing the gravel or shot,P, and the tube N and cap 0, combined as shown in Fig. 2, constitute the improved strainer, and it is held in place by screwing the lower end of the tube N into an elbow, Q, or any equivalent tubular part, andpreferably until the lower end of the cap 0, meets the upper end of the elbow, substantially as shown in Figs. 1 and 2. The elbows, Q, which sustain the strainers shown, are united by means of tubes (1 and thecross q, and the cross, in the present illustration connects, by means of the tube q, with the T, (1 which supports the.
strainer as shown, and the T in turn is joined to the pipe E, which passes out through the shell of the filter in the ordinary manner. The described support of the strainers is preferably embedded in grouting, R, which is placed in the bottom 'of 'the filter as shown. The strainer parts in practice are made of sheet copper, and the perforations, m are formed by punching the sheet from the inner side thereof.
In operation, the valves G and 1) are closed and the valves F, H, are opened, and the water then flows to the filter and passesdownward through the filter-bed and thence through the strainers into the discharge pipe E. The Water is filtered by passing through the filter-bed, and the strainers prevent the sand of the filter-bed, or whatever the filterbed is composed of, from being carried into the discharge pipe. The sand cannot very well pass into the strainer-chamber, and if any portion of it does pass thereinto it is arrested within the strainer-chamber by means of the gravel P. When it is desired to cleanse the filter the valves F, H, are closed and the Valves G and i are opened, and the water then flows from the pipe B through the lower part of the pipe 0 into the pipe E and thence upward through the strainers into the filter-bed, and passing upward through the filter-bed it agitates the same and carries 01f the dirt with it and is discharged through the Waste-pipe. The shape of the perforations in the lower part of the strainer-chamber hinders the dirt, if any, in the pipe E, and the other pipes leading to the strainers, from passing upward into the strainer-chambers. If at anytime it is desired to open the strainer-chambers the caps O, are unscrewed from the tubes, N, leaving the strainer parts free to be separated from each other and to be lifted out of the tubes,
N, an operation readily performed. It is desirable for the upper one of the strainer-parts to be crowned substantially as shown as thereby a space, on, is provided above the gravel P for the filtered water to enter and occupy before passing to the valve beneath.
I claim 1. The hereindescribed filter-strainer consisting of the chamber-parts perforated and flanged as described, the threaded tube, and the flanged threaded cap, the flanges of said chamber-parts being held between the end of said tube and the flange of said cap as described.
2. The combination of the strainer-parts m, m, perforated, flanged and shaped as described, the threaded tube N, the flanged and threaded cap 0, and the elbow Q, the flanges of said strainer parts being held between the end of said tube and the flange of said cap, and said strainer being sustained upon said elbow substantially as described.
Witness my hand this 22d day of May, 1893.
JOSEPH E. BRIGHT.
