` Application ined oetoberesisso. (No modul.)

To all 'whom z't 'may concern:

Be it known that I, WILLIAM M. SACK, of Oakland, county of Alameda, and State of California, have invented a Filtering-Faucet; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a filtering-faucet in which a peculiar construction and arrangement of the faucet and iilter render it self-cleaning, as shown hereinafter.

My invention consists in the details of the construction and application of the filter as hereinafter fully described and claimed.

The object of my invention is to provide a self-cleaning filter-faucet to avoid the necessity of taking the filter out.

Referring to the accompanying drawings, Figure l is.. a vertical longitudinal sectional view of myinvention. Fig. 2 shows the lter reversed. Fig. 3 is a modification.

Let A represent my faucet, with its pipe K and nozzle L. III its cylinder or spigot opening B, in which the spigot fits, are the two i openings a b, theformer being uppermost.

Both open into the receiving portion and conduct the liquid from the tank or other receptacle. Directly opposite to them,in corresponding positions, are the two apertures c d, the former above the latter, and both opening into the nozzle or spout for conducting the liquid away. In order to have ample space for these four apertures I construct the pipe K and nozzle L so as to have large bases where they enter the cylinder B.

Let C represent the spigot, having two oppostely-placed apertures, ef. The former is so situated as to correspond with the upper apertures, a and c, in the cylinder B, the lower aperture, f, corresponding in like manner to the lower apertures, b and d, in the cylinder B. v

Within the spigot C is the upper holdingtube, D, made to tit the spigot closely. It is put up into the top of the spigot, and extends down to the space between the apertures e and f, so as not to interfere with them, and is provided with an aperture, e', corresponding with the aperture c in the spigot, thus affording a clear passage. To the lower end of this tube D, which in Fig. 1 is beveled, so as to have a larger surface, is soldered the upper layer, E, of Wire-gauze. The lower holding-tube, F, is

beveled correspondingly, and has soldered to its upper end the lower wire-gauze, G, which fits up against the gauze E, the felt or other filtering substance being between the two. The tube F has an aperture, f', corresponding to the aperturef in the spigot. It is held in place by the tube or holding-cap H, which screws up within the spigot, as shown. This formation renders the filter easily removable from the spigot when, for any cause, it needs repair orthe felt has to be changed. It being set across the spigot at an angle presents a greater surface than if it were set at right angles, and therefore I prefer it; but I can also have the filter set directly across simply by cutting the ends of the holding-pipes transversely instead of having them beveled. This I show in Fig.3.

To show how this construction and arrangement of the faucet and lter will be'self-cleaning I will follow the course of the water or other liquid. When the spigot G is turned quarter-way around none of the apertures correspond, and no dow occurs. When itis turned toward the front the upper aperture, c, in the spigot corresponds with the upper aperture, a, in the cylinder B opening out of the receiving-pipe, and the lower aperture, f, in the spigot corresponds with the lower one, d, in the cylinder opening into the nozzle or dischargepipe. rIhe filter being between these openings, the water must flow through it, and

will leave its sediment and other impurities upon its top side. When the filter is to be cleaned turn the spigot backward half-way, so that it will be in the reverse position to that just shown. Now the lower aperture, f, in the spigot will correspond with the lower one, b, in the cylinder B opening from the receivingpipe, and the upper aperture, e, in the spigot will correspond to the upper one, c, in the cyl- Inder opening into the nozzle. The water will be forced up through the filter from below and carry off the sediment and impurities through c and c, thus cleansing the filter.

I amaware that filters have been placed in faucets before; but as far as Iknow they can- IOO I claim as new, and desire to secure by Letin place by the cap H, screwed up against the ters Patent, is- A lower tube, F, substantially as described. 1o
