FILTER.

SPECIFICATION forming part of Letters Patent No. 230,347, dated July 20, 1880,

Application tiled May 1, 1880. (No model.)

To all whom zt may concern Be it known that we, ROGER F. SCANNELL and JOHN E. LrPscoMBE, both of Boston, in the county of Sulfolk and State of Massachusetts,haveinvented anew and useful Improvement in Filters, of which the following is a specification.

rlhis invention is an improvement upon the filter for which Letters Patent Were granted io'us April 6, 1880, saidLetters Patent being numbered 226,243; and the said improvement relates entirely to the plug, which is supplied with a certain additional channel or hole and enlargements of certain portions of channels shown in the said previous invention, by

means of which the water may not only be liltered and pass through unfiltered, and the lilter be cleansed by reversing it, so that the water passes rst through pipe g in said patent zo and then through the charcoal, but in addition to all this, which is accomplished in said patented invention, the water remaining in the lilter after the reversing cleansing process may itself be ltered by passing it iirst through the charcoal and then through pipe g and then out through a waste-pipe. In other Words, an additional means for cleansing is provided, which cleanses the water left in the filter and passes it through the ilter without reversing 3o its direction.

In theaccompanying drawings, in which similar letters of reference indicate like parts,

Figure l is a longitudinal vertical section of the filter described in said Letters Patent v 3 5 with our present improvement applied to the plug in position for filtering. Fig. 2is a similar section with the plug reversed for cleansing in the manner described in said patent. Fig. 3 is asimilar section with the plug in position for the final cleansing accomplished by means of our improvement.

Fig. 4 is a horizontal section with the plug in the position shown in Fig. 1. Fig. 5 is a cross vertical sec tion of the plug, taken through the central hole therein.

5o plate b.

D is the faucet or cock, having passages c and f, the former leading to the carbonchamber A and the latter to the vertical tube g in said chamber. Passages 7L and 7c lead respectively to the supply-pipe E and the housepipe F, and passage l to thc waste-pipe G, and all said passages connect with the plug H. The plug H is provided with the channelsp q s, the hole t, and pointer m.

All the above parts are constructed and arranged as described in the said Letters Patent. Their operation is, briefly, asfollows: To liltcr the Water, turn the plug by means ofthe pointer m into the position shown in Figs. l and 4. The water enters through passage h in the supply-pipe E, passesthrough passage p in the plug and passage 'c in the faucet, up

through the carbon in the chamber A, down through tube g, faucet-passagef, plug-passage q, and passage lo in the house-pipe F.

To cleanse the filter, reverse the plug by means of the pointer m, so that it is in the position shown in Fig. 2. The water passes from passage h through channel q, passage f, up

through tube g, down through the carbon, through passage c, channel s, hole t, and pas sage l, into the waste-pipe G.

It will readily be seen that after the cleansing process above described there is still a tilterful of water, (amounting to some gallons,) Which, as soon as the plug is turned so as to let the water on to the house, must pass to the house, carrying impurities with it. By means of the improvement below described this lterful of water, instead of being turned back into the house, is turned back through the lter, as though it were going to the house, but is instead conducted to the waste-pipe.

In this improvement aconnectiomp, is made at the central end of the channelp by removing a portion of the plug at that point, and a similar connection, s', is made at the central end of the channel s. Also a hole or channel,

as desired, ism-ade, as shown by n, Figs.3 and 4. This hole or channel terminates in the hole t, and its course is shown in the two figures named. The more direct way is to carry it directly to the hole t by boring the plug, thus making a straight hole, as shown in broken lines, Figs. 4 and 5 5 but either a hole or channel is satisfactory.

The operation is as, follows After the IOO reversing process, the plug being in the position shown in Fig. 2, turn the plug threeeighths of a turn to the lef't, as shown in Fig. 8. This brings the part p of the channel 19 into connection with the passage h in the supply-pipe E, the opposite end of passage p (or a part near to the opposite end) into connection with the passage c, the end fu of s, which enters the hole t,into the passage Zot' the waste-pipe G.

Ilhus it will be seen that this cleansing process carries the water through the carbon before carrying it through pipe or tube g. The cleansing process described in the Letters Patent above alluded to did just the reverse of this.

In this improved supplementary cleansing process the water goes through thesanie Way as when being filtered.

Having thus fully described our improvement, what we claim, and desire to secure by Letters Patent, is-

In combination with the faucet D, provided with passages afl, the plug H, provided with hole t, connection s', channel p and connection p. and holeor channel o o', arranged and coulstructed to operate substantially as and for the purpose herein set forth.
