WILLIAM NERAOHER, OF CLEVELAND, OHIO.
SPECIFICATION forming part of Letters Patent No. 331,531, dated December 1, 1885.
Application filed February 18, 1885. Serial No. 156,294.
To all whom it may concern.-
Be it known that I, WILLIAM NERAOHER, of Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented a new and useful Improvement in Filter Attachments for Faucets; and I do hereby declare that the following is a full, clear, and exact description of the 53,1116.
My invention is an improved attachment for faucets for the purpose of connecting a filter to the faucet, the said attachment being also combined with a reversible form of filter designed as a faucet-filter.
In the accompanying drawings, Figure 1 shows the faucet and attachments in side eleva- Fig. 2 shows a perspective view of the attachments. Fig. 3 is a detail.
In the drawings an ordinary basin-faucet is represented by A, and B represents a filter to be connected with the stem a of the faucet. The filter has a plug, b, provided with a threaded stem, 0. A cap, (1, with interior thread, is fitted to this stem, said cap having a seat, 1, for a packing, 2, and an opening, 3, for the admission of the end of the faucet-stem a. On one side of the opening 3 is a curved arm or yoke, e, of shape in curve and crosssection to fit the curved end of the faucet-stem, in order that no lateral movement be permit ted the curved arm. To the upper end of this is fixed a ring or collar, f. The whole is adapted to slip over the curved end of the round faucetsteni, so that the end of the stem will enter the hole 3, where it may fit closely in the packing-ring 2. This preventsleakage and allows the water to pass to the filter, the packing serving for both the plug-stem and the end of the faucet-stem. This construction of the arm or yoke enables the setscrew to hold the filter securely against any force of the water, and also prevents it from turning on the faucet-stem.
The filter B is reversible. Its nozzle may be shifted to the other end and its place taken by the plug, so that the position of the filter may be reversed for cleaning. The ring or (No model.)
collar is held to the faucet-stem by aset-screw, 5, and the device may be easily applied or removed. The form of the arm or yoke 0 may be changed.
The filter itself is especially designed to serve as a faucet-filter where compactness is required. For this purpose it is made with cylindrical ends to receive the necessary screen and packing and with a swelled central part to give an enlarged chamber for the charcoal or other filtering material.
In order to secure in asimple, compact, and
effectual manner the screens in the cylindrical ends, I have devised a special form of seat for the ring-packing and screen. The screen l rests on a depressed seat, 111.. A little above this is a seat for the packing-ring a, made of greater diameter than the threaded part of the bore above and larger than the diameter of the screen. The ringpacking is sprung into this seat and overlaps the screen, resting on it and on its own seat, thus making a water-tight joint around the edge of the screen. The enlarged seat also holds the ring against the pressure of the water and retains it in place when the plug or nozzle is removed. This construction leaves chambers 0 at each end over the screen and admits the water freely thereto. The plug or nozzle is screwed in over the ring, and leaves a chamber within the ring.
I claim In combination with the filter, the cap (1, threaded to fit the stem of said filter, having a packing-ring and opening for the stem of the faucet, the arm or yoke e, curved to conform to the curve of the faucet-stem, and the ring or collar provided with a set-screw for attachment to the faucet, all substantially as de scribed.
In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
