SPECIFICATION forming part of Letters Patent No. 674,297, dated May 14, 1901.

Application filed September 1, 1900- Serial No. 28,804. (No model.)

To (ZZZ whom it may concern.-

Beit known that I, LOUIS KOSIOL, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Overflow'and Waste Fixtures; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to overflow and waste fixtures for sinks, bath-tubs, basins, &c., and is an improvement upon the fixture shown and described in United StatesLetters Pat ent No. 630,718, granted to me August 8, 1899, the object of which, as described in my said patent, was to enable the waste-pipe to be kept clean and clear, the trap to be cleaned when desired, and to prevent freezing thereof, and it also provided means whereby the water could be forced out of the trap at will, while the escape of Waste water from the fixture was controlled and the inflow of sewer-gases prevented, and said device was also adapted to act as a plug to prevent the escape of the water from the fixture to which it was attached when desired.

The present invention embodies substantially all the advantages of the device shown in my aforesaid patent, and in addition has a constantly-maintained water seal toprevent entrance of gases into the building through the fixture, even when it is in such condition that water may readily escape thereth rough.

The present invention therefore consists in the novel and improved construction and combination of parts hereinafter claimed, and illustrated in the accompanying drawings, in which Figure l is a sectional elevation of my improved waste device, showing the parts adjusted to permit escape of the water, while maintaining a water seal and preventing backflow of gases. Fig. 2 is a similar view showing the position of the parts when a permanent seal is formed or the position of the plunger and valve when adapted to be used as a piston.

A designates a basin or other fixture, to the outlet of which is suitably connected a tube D, to the lower end of which is attached a within the central recess f of the perforated plunger F. One end of this spring bears against the head of the valve-stem e, and its,

other end is adapted to bear against the lower end of said recess. This spring, however, is not essential to the practical operation of the valve, but may be found advantageous to facilitate its operation.

The plunger F is provided with exterior packingf to fit it tightly within the tube D and with a depending ann ular conoidal flange or extensionF on its lower portion surrounding the opening in the plunger. The lower end of flange F depends into the cup-valve E, as indicated, and as the cup-valve is normally full of water the lower end of the annular flange F will be submerged in the waterin cup E and will form a water seal below plunger F, although water may readily descend through the plunger and overflow the valve E and thence escape, as is obvious. When the plunger is pushed entirely down, as shown in Fig. 2, the cup-valveEis pressed closely to the seat 01, and the flange F also fits closely in the valve E. The water seal can be constantly maintained, however, between the valveE and plungerF. On the outer end of the valve-rod f and Within the basin is formed a circular handle 0, and depending from the lower side thereof and parallel with the valve-rod are two depensions or rests c.

In the outlet of the basin or fixture A. is fitted a strainer B, which, as shown, is preferably provided with holes 1) sufliciently separated and large enough to admit the rests c. The strainer is also provided with a series of small apertures, and obviously when the rests are above the strainer the valve is open,but when pushed down through the openings 12 the valve is closed.

Instead of the tube D being connected directly to the fixture and the strainer fitted to the tube, as shown, the tube may be secured to an adjustable collar or coupling at the waste-opening. As shown, the waste-outlet pipe may also be provided with an outlet (1 below the valve-seat for, the purpose of attaching a back vent. Of course it is understood that a swivel, as well as a straight outlet, may be employed, as illustrated by dotted lines in Fig. l.

l'Vhen the plunger and valve are seated, as shown in Fig. 2, no water can escape from the fixture nor can any gas enter therethrough, as a double closure is formed between the seat (1 and valve E and between the valveE and flange F. If the plunger is slightly raised, as indicated in Fig. 1, water can escape through the fixture, as is obvious, passing through plunger F and around'the valve E but at the same time it will be observed that no gas can escape upwardly through the tube D, because of the water seal constantly maintained between the valve E and the flange F of the plunger.

If the plunger and valve are raised to the highest position and then suddenly depressed, the valve E willbe forcibly seated against the plunger F, particularly if there be any water in the tube D, and these together will form a tightly-fitting piston in the tube D, and the air, water, or other matter below this piston will be forced downward, and thus water or other obstacles below the piston and plunger can be forced out of the pipe.

Having thus described my invention, what I therefore claim as new, and desire to secure by Letters Patent thereon, is-

1. In an overflow-fixture for sinks, &c., the combination of a waste tube, the plunger therein having a passage for the water, and a depending flange surrounding the passage; with the cup-valve suspended from and below said plunger and projecting above and around the lower edge of the flange, and adapted to retain water to form a water seal between the valve and plunger, substantially as and for the purpose described.

2. The combination of a tube attached to the outlet of the fixture, the valve-seat at the lower end of the tube, the movable plunger in the tube having a water-passage and a depending flange surrounding such passage, and the cup-shaped valve suspended from said plunger and adjustable therewith within the tube and adapted to close the outlet when the plunger is sufficiently lowered, and also to form with the flange a constant water seal when the plunger is raised, substantially as described.

3. The combination of the waste-tube, the valve-seat at the lower end of said tube, the adjustable plunger within said tube and the plungerrod; with the cup-shaped valve loosely suspended from said plunger and adapted to close the outlet when the plunger is fully lowered, and to form with the flange a constant water seal when the plunger is raised, and means for holding the plunger in open position, for the purpose and substantially as described.

4. The combina'on of the water-fixture, the waste-tube connected therewith, the valveseat at the lower end of said tube, the annular plunger within said tube tightly fitted therein provided with a water-passage and a depending flange surrounding such passage, and the plunger-rod projecting into the fixture; with the cup-shaped valve loosely suspended from said plunger and adapted to close the outlet when the plunger isfully lowered and also adapted to form with the flange a constant water seal when the flange is raised for the purpose and substantially as described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
