SPECIFICATION forming part of Letters Patent No. 644,537, dated February 27, 1900. Application lled May 18, 1899 Serial No. 717,341. (No model.)

' To all whom, t may concern:

A particular object of the present invention 1 is to provide means for the cleaning of theV interior of t-he filter and the loosening of the coke or other filtering material to adapt it for further efficient use.

Furthermore, it is an object of my invention to provide improved means for attaching the filter to a faucet.

Further objects and advantages of this invention will appeal' in the following description, and the novel features thereof will be particularly pointed out. in the appended claims.

In the drawings, Figure 1 is a perspective View of a filter constructed in accordanceA with my invention. Fig. 2 is a sectional view of the same, the reversing-valve casing being shown in elevation. Fig. 3 is a sectional View of the reversing-valve on the plane indicated by the line 3 3 of Fig. 2.

Similar reference characters indicate corresponding parts in all the gures of the drawings.

1 designates the cylindrical body of the casing, in which is arranged the `filtering material 2, such as granulated coke, supported between perforated upper and lower diaphragms 3 and 4. The upper diaphragm,'as in the construction illustrated in my said former patent, is held in place by a spider or follower 5, actuated by a pressure-screw 6, the shank of said screw being arranged to extend through a stuffing-box 7, formed in the casing-cap 3, and the lfollower being provided with a central projection 9, extending upward into a depending thimble 10 in the path of the lower end of the pressure-screw. Said casing-cap S is secured in place by means of threaded studs 11, projecting upward from a dared iiange at the upper edge of the casing through openings in the cap and engaged by thumb-nuts 12, and as the outlet-faucet 13 of the filter is carried by said cap at an eccentricvpoint it will be understood that by engaging different openings of the cap with the threaded studs 11 said outlet-faucet may be arranged in either of a plurality of positions lwith relation to the body of the filter to suit the convenience of the operator. A gasket 14 is seated in registering grooves in the facing-,surfaces ofthe cap and casing-cylinder.

Communicating with the casing through a lateral ush-port'l, located above the plane of the filtering material 2, is a reversing-valve casing 1G, inclosing a double-faced or reversing valve 17, arranged to operate between spaced seats 18 and 19, and communicating with the valve-casing between the planes of said seats is a coupling-arm 20, terminally constructed with a coupling or union 21 for engagement with a faucet 22, said coupling-arm having a rocking or swivel connection with the valve-casing 16 to adapt the casing to be moved independently of the coupling-arm to suit the inclination of the discharge end of the faucet 22 and the preference of the operator. In the construction illustrated the coupling-arm is threaded in an opening in the side wall of the valve-casing 16, and also threaded upon said coupling-arm is a jam-nut 23, adapted to be adjusted toward the valvecasing to lock the parts at the desired adj ustment. Preferably a rubber gasket 24 is interposed between the adjacent faces of the jamnut and valve-casing.

The ilush-port 15, which communicates with the filter-casing above the plane of the filtering material or medium, also communicates with the reversingvalve casing above the plane of the upper Valve-seat 18, while communicating with the valve-casing. below the plane of the lower valve-seat and controlled by the reversing-valve when arranged upon said lower seat is a feed-pipe 25,.which extends to and com municatesV with a feed-port 26, which opens into the filter-casing below the plane of the filtering medium. In the construction illustrated a swivel coupling or IOO union 27 is employed to form the connection between the feed-pipe and a threaded nipple 2S, which communicates with said feed-port.

At the lowerend of the lter-casingis asediment receptacle or pocket 29, preferably connected with the interior of the casing by a narrow port 30, formed in the neck portion of the casing, and communicating with this sediment-pocket is a drain-valve mechanism consisting ot a valve 3l, having a tubular stem 32, with the bore of which communicate ports` 33, normally arranged within the guide ofthe \falvestem, but adapted to be arranged in communication with the interior of the casing when the valve S1 is unseated. The stem extends through a stuffing-box having a gland 34 to prevent leakage when the drain-valve is unseated, and said stem below the stufiing-box is provided with a grip or hand-wheel 35. It will be noted that the drain-valve is constructed to seat downwardly and to rest directly upon a seat-surface which is in a plane perpendicular to the direction of movement of liquid or other material in leaving the casing through the port controlled by said valve, whereby the pressure of the contents of the casing serves to assist in maintaining the valve operatively seated. The same construction of valve is used in the reversing-valve mechanism, wherein the member 17 operates between parallel-faced valveseats 18 and 1f).

The iilter-outlet-valve mechanism includes a casing 3G, with which communicates the filter-faucet 37, and the valve 3S, which is arranged to close against and seat in a direction perpendicular to the path of movement of water entering the casing 3G. The valve consists of a disk 39 of metal or similar material and a packing-disk 40, the metallic holdingdisk being secured in place by means of a screw 41 or the equivalent thereof, and it will be understood that the other valves included in the iilter mechanism are similarly constructed.

I have found in practice that after water has been passing through a iilterin one direction for a time the filtering material particularly adjacent to the plane of that diaphragm through which the water first passes becomes caked or adhesively connected by glutinous substances and that when the direction of the fiowof water is reversed, while it removes the loose accumulations of foreign material, it fails to break up the cake of granulated coke or other material. Therefore in the iilter embodying my present invention I construct the lower diaphragm to yield in a direction opposite to that in which the water ordinarily moves in passing therethrough, whereby when the direction of ilow ot' water is reversed this diaphragm is moved or displaced and to a certain extentvibrated to cause the efiicient shifting of the particles of coke within the space between the diaphragms, and particularly adjacent to the lower diaphragm, whereby the cake is broken up and cumulatons.

the parts of the mechanism returned practically to their original condition. In the construction illustrated the lower diaphragm is yieldingly held in its normal or operative position by means of springs 42, consisting of coils from which extend arms 43 and 44, the former bearing against the under side of the diaphragm and the latter against fixed objects within the casing. I preferably construct each spring of a single blank of wire doubled upon itself at its center to form a loop, of which the closed end forms the upper arm 43 and of which the extremities are turned downward to form studs 45, which [it in sockets in lugs 46, cast upon orsecured to the inner surface of the casing below the plane of the lower diaphragm. Hence in practice the water which is supplied by the faucet enters the reversing-valve casing and passes from thence, when said valve is in its normal position, through the feed-pipe 25 to the interior of the filter-casing below the filtering medium. Particles of solid material which may be in the water are allowed to settle in the sediment chamber or receptacle 29, while the passage of the water through the intermediate portion of the casing between the planes of the sediment-chamber and the filtering medium does not serve to disturb the contents of said chamber. After passing upward through thc filtering material the water may be withdrawn through the lteroutlet-valve, as required. After the apparatus has been operated for a length of time sufficient to cause an accumulation of dirt the drain-valve should be opened and the reversing-valve re- IOO versed to cause water from the faucet 22 to enter the filter-casing through the flush-port 15, whereby it passes downward through the filtering medium and carries with it said ac- This downward movement of the water through the medium, however, serves to depress the lower diaphragm 4 and thus agitate and vary the positions of the particles of granulated coke, whereupon the filtering medium operates suiiiciently when the several parts are returned to their normal positions.

In practice various changes in the form, proportion, size, and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
