BENJAMIN R. CIIEV, OF IARLINVILLE, ILLINOIS.
WATER STRAINER OR FILTER.
SPECIFICATION forming part of Letters Patent No. 453,547, dated June 2, 1891.
Application filed February 5, 1891- Serial No. 380,385. (No model.)
To all whom it may concern.-
Be it known that I, BENJAMIN R. CHE\v,of the city of Carlinville, Macoupin county, State of Illinois, haveinvented certain new and useful Improvements in ater Strainers or Filters, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to improvements in water strainers and filters; and it consists in the novel arrangement and combination of parts, as will be hereinafter more fully described, and designated in the claim.
In the drawings, Figure 1 is a side elevation of my complete invention, showing the same as applied to a pump; and Fig. 2 is a vertical longitudinal mid-section of the same, taken through the primary or sediment chamber and also the secondary chamber and spout. Fig. 3 is a top plan view of a primary chamber with parts broken away.
Referring to the drawings, 1 indicates a circular or secondary chamber, from which the filtered or strained Water passes to the bucket or receptacle through a spout 2. A portion of one side of said chamber 1 is cut away, and placed in lieu thereof are three sieves of clifferent mesh. The sieves are made of wiregauze or perforated sheet metal or constructed out of any suitable filtering material.
3 indicates the inner of said sieves, which has the finest mesh of the three. Said sieve occupies the first position or forms the first stratum relative to the inner surface of secondary chamber 1.
4 indicates a sieve having a larger mesh, which is placed on the outside of sieve 3. Said sieve occupies a secondary position and forms a second stratum relative to the internal surface of secondary chamber 1.
5 indicates a similar sieve of still larger mesh than either of the sieves 3 and 4, and the same is placed on the outside of sieve 4c. Said sieve occupies the third position and forms a third stratum relative to the internal surface of secondary chamber 1. Said sieves 3, 4:, and 5 are secured to secondary chamber 1 in any suitable manner, preferably by being soldered.
6 indicates a primary or sediment chamber, which is secured to secondary chamber 1 by being soldered to the same, as shown in Fig. 1. Said primary chamber 6 is approximately crescent shaped and tapers downwardly, thereby forming a chamber when secured to secondary chamber 1 of irregular dimensions, the bottom or lower dimensions thereof being smaller than the upper. Said primary chamber 6 is provided with an orifice 7, in which orifice the spout 8 of an ordinary pump is adapted to be inserted. Situated in the bottom of said primary chamber 6 is an automatic valve 9. Said valve is mounted upon the stem 10, on which it is free to move upward and downward. Said stem is secured in an upright and vertical position by means of cross-pieces 11 and 12, respectively. Crosspiece 12 is rigidly secured in a screw-threaded nozzle 14, and cross-piece 11 is likewise secured to the internal surface of the bottom of primary chamber 6. The upward motion of said valve is effected by a spiral spring 15, which encircles stem 10 and on which said valve is mounted. The valve is closed or pressed downward by the water or hydrostatic pressure received in said primary chamber 6. The end of said stem terminates in an eyelet, in which a cord 17 may be tied,which cord is also secured to a screw-cap 18, which cap is adapted to be screwed 011 said nozzle. Said valve 9 isprovided on its lower or contact surface with a rubber or cork covering, which rests circumferentially on an opening formed in the bottom of said chamber 6 as a valveseat.
Secured to the bot-tom of secondary chamber 1 are cleats 19, in which resting or supporting plates 20 are adapted to pass. Said plates are rigidly secured to the body of the pump by any suitable or mechanical means, and are also removable therefrom when desired. By this construction it is readily perceived that the filter or strainer is adjustable to and from the body of the pump, as desired. For instance, as is often the case, the spout of one pump is longer than ordinary pumps. The filter can be removed outwardly from the pump, thereby bringing orifice 7 under the spout, as desired.
Having fully described my invention, I will now proceed to describe its functional use.
The filter is essentially adapted to be used in connection with cisterns, as there is generally more animal and vegetable impurities in cisterlrwater than in any other. The water on being received in the primary or sediment chamber 6 will close valve 9, thereby preventing any animal or vegetable suspensions from passing out of said chamber. The sediment will collect in the bottom of said chamber and can be removed therefom through the orifice and nozzle formed therein when valx e 9 is opened or elevated. The strata of sieves 5,4, and 3, being of different degrees of mesh, would efiectually strain out and remove all the suspensions contained in the water. Said suspensions will accumulate in the form of sediment in the bottom of said chamber 6, and from thence can be removed as aforesaid.
I am aware that prior to my invention filters having two chambers have been constructed in which two valves were so connected together that one was necessarily closed by the inflow of water and that filtering-diaphragms of different degrees of coarseness have been used, and I do not therefore claim such a construction; but
What I do claim is A filter consisting of two communicating adjoil'iing vessels secured together, one of the said vessels forming a secondary chamber and being cylindrical, the opposite vessel forming a primary chamber and being crescent-shaped in plan view and being reduced in area at the bottom, vertical Wire screens dividing the said chambers, the coarser of the said screens being near the primary chamber and the finer near the secondary one, the said primary chamber having an aperture therein, a flat valve covering the said aperture, a spring tending to force the said valve up against the hydrostatic pressure of the water, and a threaded cap adapted to close the said aperture, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
