UNITED STATES PATENT OFFICE;

FILTER.
1 ,oeazae.
Application filed September 26, 1913.
To all whom it may concern Be it known that I, Janus M. Convert, a citizen of the United States, and a resident of Ossining, in the county of estchester and State of New York, have invented certain new and useful Improvements in. Filters, of which the following is a specification.
My improvements relate to the class of self'cleaning filters for the purification of water and other liquids in which the flow of the liquid is reversed through the filtering mediumthe filter being designed prima ril v for attachment to a faucet or other source of liquid supply, as when used for the purification of water for domestic purposes, although the essential features of the invention are applicable to various other uses.
The object of the invention is the pro duction of a simple, compact, and effective reversible filter of the character designated, of moderate cost, controlled by a single conical valve plug, only one end of which (that to which the handle is attached) protrudes through the casing, which latter is adapted to receive and support an integral filter cartridge which may readily be inserted, removed. and duplicated when expedient.
Hence the invention consists in the formation and arrangement of parts herein shown and described and claimed specifically. a distinctive feature being the provision of an axial discharge duct in the reversing plug in conjunction with a circuitous discharge passage in the casing as hereinafter set forth, whereby I am enabled to greatly simplify both the construction and operation of the device.
In the accompanying drawings, Figure '1, is what may be designated as a front elevation of my improved self-cleaning filter; Fig. 2, a rear elevation; Fig. 3, a right hand side elevation; and Fig. 4, a. left hand side elevation; 5, is a central vertical section of the filter, full size, taken upon plane of line 5-5 Fig. .2; Fig. 6. a sectional elevation taken upon plane of line 6-6 Fig. 5; Fig. 7 a sectional detail showing means for restricting the axial move ment of the reversing plug.
The barrel or casing C is formed with the internally threaded nipple c, for attachment to a water faucet or other source of liquid supply, and with an. inlet 0, and lateral circuitous discharge conduit 0 lead- Specification of Letters Patent.
Patented June 9,1914.
Serial No. 791,896.
ing to the outlet (1. Interposed between the inlet. 0, and the discharge conduit is the conical plug P, formed with the axial discharge passage 1) which is in constant (itllllll'llllllctttlOll with the said circuitous discharge conduit c as shown in Fig. (3, and with the ports 7), 72* opening into said axial passage 7), said plug P being also formed with the peripheral port p communicating with the inlet (1, as shown more particularly in Fig. 5, said peripheral port p be .ing approximately semi-circular in extent; so as to communicate with either of the internal ports 0, 0, formed in the casing (l. as shown particularly in Fig. These in ternal ports 0', 0" communicate with the spaces in the casing C, on either side of the filter cartridge F, when the latter is positioned in saidcasing as shown in Fig. 5. The filter cartridge F is cylindrical in form, its closed ends being perforated or intersticed for the passage of the liquid to be filtered, and it is filled or charged with any suitable filtering medium, as sand, charcoal, &c., preferably with a central disk f of relatively close porous material practically dividing the filter into compartments and acting as an effectual barrier to the passage through the filter of the foreign matter which it is sought to eliminate from the liquid.
The filter cylinder F, is formed with an annular flange f, which is threaded peripherally to engage with the female thread c, tapped in the body of the casing, which female thread 0, not only affords means for positioning the filter cylinder F, but also for the attachment of the closure cap C. as shown in Fig. 5. The flange f of the filter cylinder F is formed with the annular shoulder f between which and the seat a, of the. casing is interposed a gasket 9, which prevents the passage of liquid from one side of the casing to the other except only through the filter F. Gaskets are also interposed be tween the outer flange 0" of the cap C and the opposed surfaces of the casing as shown in Fig. 5, to insure against leakage.
The conical portion of the reversing plug P, is accurately ground to a water-tight fit with its seat in the casing C, and is of such length that its shoulder 72 extends slightly beyond the annular packing shoulder 0 formed in the casing for the reception of the gasket g,-said gasket resting upon both said shoulders p, and c and being interposed between them and the inner surface of the tightening nut n, which fits over the cylindrical portion 79* of the reversing plug P,
and is formed with a peripheral. thread n,
for engagement with the female thread in the casing. I thus afford ready and convenient means whereby wear between the reversing plug and its seat may be taken up and compensated for, at the same time insuring a fluid tight joint at the protruding end of the plug, which may be provided with the usual handle it, or other means whereby it may be partially rotated on its axis,the extent of such motion being limited by a stop 0 on the casing arranged for engagement with shoulders 0 p", on the plug, as indicated in Figs. 6 and 7 or by resort to any other well known mechanical expedient.
In operation when the parts are in the position shown in Fig. 5, (the stop 0 being in contact with the shoulder 37 the flow of liquid will be through the inlet 0, peripheral port 79 and internal port 0 to and through the filter F to the internal port 0 and through the radial port 77 to the axial discharge passage 79, by which the liquid will be delivered to the circuitous conduit 0 to be discharged through the outlet 0 By reversing the handle it, until the stop 0 contacts with the shoulder 39 the liquid will flow through the inlet a, peripheral port 19 internal port '0 filter F, internal port 0 radial port 19 and axial passage 7), to the circuitous conduit 0 and. thence through the outlet 0 Thus a simple motion, a partial turn of the conical plug from one stop contact to the other, will suflice to reverse the flow of the liquid and wash out and eliminate from the filter any foreign matter that 7 same time I dispense with one end packing for the plug,-the handle end thereof alone projecting through the casing.
What I claim as my invention and desire to secure by Letters Patent is,
A filter of the character designated, com.
prising a casing adapted for connection with a source of liquid supply, a filter cartridge mounted in said casing and dividing it into two compartments, said casing being formed with ports communicating respectively with said compartments, a valve plug seated in said casing and interposed bet-ween said casing ports and the inlet, and formed with an axial discharge passage and with radial ports communicating therewith and alter nating with the casing ports, said plug being also formed with a peripheral port co-mmunicating with the inlet and alternating with the casing ports, said casing being also formed with a circuitous discharge passage connecting said axial discharge passage in the plug permanently with the outlet, whereby the flow of liquid-through'the filter cartridge may be reversed and the discharge of liquid maintained through the axial passage in the plug, for the purpose described JAMES M. GOLVEN.
