FILTER.,

SPECIFICATION forming part of Letters Patent N o. 541,755, dated June 25, 1895.

Application tiled January '7, 1895. Serial No. 534,127. (No model.)

To all whom t may concern,.-

Be it known that I, JOHN WV. JARRETT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Filters, of which the following is a specification.

My invention consists of a novel filter constructed as hereinafter described and claimed.

Figure 1 is a vertical section,'partly in full lines, of the improved filter complete, and Fig. 2 a front view of the upper portion of the same. Fig.3 is a plan view of the distributer and sieve or strainer. Fig. 4 is a section, partlybroken away, of the improved valve.

Referring to said drawings, the filter proper consists of a glass or other suitable shell or cylinder A provided with heads B B each containing an inwardly projecting annular ange or ledge b h whereon are placed rubber or other gaskets c c', and the ends a a of duced diameter, as shown, or not,-have sin1ilar gaskets a2 a3 thereon, and between the respective gaskets are interposed the separators or distributers D D and the sieves or strainers E E,.in the order named, the whole being clamped together in the relation shown in Fig. 1 by tie-rods or braces F, of which there may be any number, which rods or 'braces pass through an equal number of external lugs b2 b3 on each ofthe heads B B and are provided with enlargements fand nuts f', or may have `nuts at each end, for the usual purpose.

As will be observed, the separators or distributers D D are concaved or dished and inverted relatively to the interior of the shell or cylinder A, having perforations d CZ in comparatively fiat portions of the same which are substantially parallel with the said sieves; of which perforations there may be any number consistent with the result sought to be attained. The spaces between said separators or distributers andthe ends of the respective heads B B forming separating or distributing chambers B2 B3, access whereto is had through the threaded openings b4 b5 with which said heads are provided. Y

The improved cock or valve G consists of a casing g provided with four externallythreaded radial arms g g2 g3 g4 and a stem h, with cavities or recesses h h2 therein, for registry with the ports h3 h4 h5 h6 in the respective arms, which stem terminates in a handle H. Onto the upper one of the arms, or branches, is screwed a 'connection z' which at its other end is screwed into the upper one b4 of the threaded openings lmentioned and affords a means of communication between the valve and the upper distributing or separating chamber B2, and to the lower arm g3 of the cock or valve G is coupled, by a union 1J', a vertical pipe I which at its lower end, is threaded for reception of another connection t2, the other end of which latter is threaded as at i3 wherebyitis screwed into the threaded opening b5, thus establishing communication between said pipe and the lower distributing or separating chamber B`,' while the side arms g2 g4 of the cock or valve-casing,which `contain the inlet and outlet ports, are provided with nozzles k 1c', adjustable to Vany angle, for-reception of hosethough,of course, these nozzles may be dispensed with and said side arms connected directly to any suitable supply and discharge pipes, as desired.

Now, assuming the filtering material to have been already placed in the filter with that one of the sieves or strainers E Eas a base'which is lowermost,-it beingunderstood that this lilter may be stood on either'end to equal advantage,-with the valve set in the position shown in Fig. 4 and the handle H inthe position illustrated by the dotted lines in Fig. 2,where it is limited against further movement in that direction by the stop g5, the course of the unfiltered water will be from supply-nozzle k', through ports h4 h3, in the direction indicated by arrow l, and through the connectionz' to the upper chamber B2, when it passes through and undergoesa preliminary straining by the separator or distributer D, while having the force with which it strikes the sieve or strainer E diminished thus lessening the chances of the latter bel, coming choked up or having the foreign particles driven into the meshes thereof. After passing through the filtering material L, 'the water passes through the sieve or strainer E and the separator or distributer D to the chamber B3,.thence out through connection Z2, pipe I and ports h5 h6, in the direction indicated by arrow 2, to the discharge-nozzle For cleaning out the filter, as is at intervals IOO necessary with this and all other filters, the handle H of the cock or valve is thrown over into the position shown in full lines in Fig. 2, where it is limited against further movement in that direction by the stop gs; bringing the stem ot' said cock or valve into a position the reverse of that shown in Fig. 4 and the concavities h h2 therein establishing communication between ports h4 and h5, h3 and h6, respectively, in which event the course ot the water will be from nozzle la to and through pipe I and connection i2 to the lower chamber B5, from whence it passes through the openings CZ', which are in a comparatively flat portion of the lower separator or distributor D and is divided into as many separate jets or streams, in which condition the water t strikes the sieve E at substantially aright angle or vertically, agitating the same, and passes through the filtering material L, the upper sieve E and separator D, to the chamber B2, wheref rom it seeks egress thro ugh connection z', ports h3 L-and nozzle lt to the dis charge-pi pe or tube.

From the-disposition of the' openings-in the separators or distributers aforesaid,itwill be seen that the filtering material will beiquiite` thoroughly agitated by the application of the water thereto in this divided condition frombeneath, insuring a perfect cleansing of the, same without resort to` other means or devices l for securing such agitation, while the screen i abo-ve such material serves to con tine it within proper bounds.

IE at any time it be desirable or necessary to cut out the filter altogether, the same may be accomplished by setting the valve halt-way between the positions above described, or in the position shown in Fig. 1 of the drawings, as will be readily understood.

Whatl claim as my invention is as follows:

1. In a filter, the head B' connected therewith at the outlet end thereof, the sieve E connected with said cylinder and head and having the filtering material seated thereon, and the distributerD having perforationsin a comparatively Hat portion of the same and secured tosaid cylinder below said sieve, said parts being combined substantially as described.

2. A lter having a body with heads, stationary sieves connected with said body and i hieadstiorming chambers between said heads 4'and` sieves, pipes communicating with said g chambers, and a distributer connected with 1, the lower oneiof said headsla'nd below the corresponding sieve, said distributcr having a comparatively (iat portion` substantially parallel with said sieve with openings therein, lsaid parts being combined substantially as described. i InV testimony whereof:l l have hereunto set my hand this 3d day of Jan-nary, A. D. 1895.
