CHARLES WV. ONEILL, OF PEORIA, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 765,749, dated July 26, 1904.

Application filed February 9, 1903. Serial No. 142,657. (No model.)

To all whom it may concern:

Be it known that I, CHARLES IV. ONEILL,

` a citizen of the UnitedStates, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in a Combined Slop Hopper, Floor-Drain, and Backwater-Trap; and I do hereby declare that the following' is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a combined slop-hopper, Hoor-drain, and backwater-trap, and has for its object a device of the class described which is simple in construction, cheap at first cost, and well adapted for the purposes for which it is designed.

The invention comprises in its structure a cone-seal detachably supported in a suitable hopper.l a seamless spherical oat adapted to close the lower end of the seal, and an outletconnected with the hopper for conveying off water, which said outlet is provided with a supplemental swinging valve as a safeguard against a backflow into the hopper and an air-vent leading off from the outlet through which gases'accumulating in the outlet will pass off.

Further objects of the invention will become apparent from the Jfollowing description, and drawing accompanying said description,

in which the gure shows avertical sectional View of my device.

Referring to the drawing, l indicates a suitable hopper, shell, or trap portion having an inverted-dome lower portion 2, tapered side walls, and an annular ange 3 at the upper edge thereof. Approximately half-way down the hopper leads off an outlet-pipe 4 of suitable diameter, and the opening leading into the outlet-pipe from the hopper is controlled by a swinging valve 5, pivoted at 6, which normally closes the opening aforesaid. At a suitable point on the outlet-pipe 4 is connected a vent-pipe 7, leading out into the open. This vent may be in the position shown or in any other desired position convenient for use.

8 refers to a cone-seal extending down into the hopper l, with its lower edge forming a ring 9, around which is secured a rubber ring or gasket l0, which is slipped on over the ring 9, as shown. The lower edge of the seal is placed a suitable distance from the bottom of the hopper and is adapted to be sealed by a seamless copper spherical float 9a in the manner shown in the ligure. The upper enlarged-end of the seal 8 has a ange 11, corresponding to the fiange 3 of the hopper, and lies upon the same when in position and is secured thereto. When in working position, the upper face of the flange 11 of the seal 8 is designed to lie flush with the upper face of the floor or other place in which the device is secured. 1

l2 indicates a perforated strainer of aplate adapted to be supported a suitable depth in the seal 8 upon the lugs 13 for dividing the cone in the manner shown.

Then 1n operation, the water or refuse hquid is poured in the cone-seal. Passing through the perforated strainer temporarily dislodges the ball from its position, closing the lower end of the seal, and the water rising in the hopper passes out through the outlet and in so doing opens the swinging valve described, which automatically closes itself. The provision of a ball-oat and a supplemental valve, such as valve 5, is readily apparent. Should the valve 5 fail to stop any backwater iow, which might easily occur in the outlet, the ball 9a will rise and positively engage the gasket on the lower edge of the cone and seal the same. The vent connected with the outlet provides for taking off all odors or gases which might otherwise pass beyond the valve 5 and the ball 9.

Another advantage in the structure herein is its adaptability to the various uses outlined in the preamble of the specification, all of which is readily apparent to those skilled in the art. The structure is also such that by the removal of the cone 8 the entire device may be easily got to by the user and as easily replaced.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

In a device of the type set forth, the combination with a hopper having tapered lower IOO Side Walls, one Wall extending1 at substantially right angles centrally thereof to form a oonduit, an upwaidly-projecting lug formed integral with the Conduit portion near the end thereof, a Hap-valve pivoted above the said lug' in the conduit and adapted to engage the Ing', a tapered trap having' interiorly-disposed lugs therein, a seat-forming; flange formed at the lower end of the trap, a resilient means carried on Said Seat', and ay foat- 10 valve adapted to engage Said means, suhstantially as set forth.

In testimony whereof I affix my signature in presence of two Witnesses,

CHARLES ONEILL. Vitnesses:
