FLOOR-DRAIN.

I Specification of Letters Patent. Patented Sept. 28, 1909- Appkication filed November 11, 1907. Serial No. 401,584.

To all whom it may concern:

Be it known that I, GEORGE J. DEHN, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Floor- Drains, of which the following is a full,

' has been laid, and which when connected to thedrain-pipe cannot be displaced while the floor is being laid.

The invention further. designs to provide a combined drain and trap of improved construction in which a body of water supplemental to that in the trap-pipe, is retained to prevent seal in the trap-pipe from becoming iiie-J ective froifh evaporation of the liquid therein.

The invention still further 'designs to provide a drain and trap of improved and simpie construction, the several members whereof can be quickly and easily connected against displacement and which can be produced at a low cost.

The invention consists in the, several novel features hereinafter set forth and more particularly defined by claim at the conclusion hereof.

In the drawings: Figure 1 is a vertical section of a device embodying the invention. Fig. 2 is a plan. Fig. 3 is a horizontal section on line 33 of Fig. 1, the drain-pipe and basin being shown in relative position assumed before the latter has been turned to secure or look it to said pipe.

A trap-pipe A is formed with the usual bend a disposed below the lowest portion of the orifice in the return-bend or horizontal portion a of said pipe to form a chamber for a body of water which forms a seal to preventobjectionable gases from the pipe or sewer to which it may be connected, from escaping through the inlet-terminal of the trap-pipe. The outlet-terminal of the trappipe is provided with a flange a whereby it may be secured to a section of pipe leading to the sewer or discharge.

The inlet terminal a of the trap extends vertically and'is provided with an integral annulus or flange a adapted to form a seat or wall for the base-rim b of a drain-receiver B. The outer wall I) of the receiver is flared upwardly or extends outwardly and upwardly from its base-rim to form a receiving-basin and is provided with a top-flange or rim b An annular recess or shoulder 79 is formed in the receiver to retain a perforated: strainer-cover C which usually is disposed so it will be flush with the top of the basin and removably held therein, to provide access, when desired, to the trap and basin.

A lock or connection is provided between the trap-pipe and the receiver whereby the basin will be secured against displacement with the pipe and a water-tight joint is provided between the pipe and the basin. This connection comprises a series of ribs or lugs a, integrally formed on the trap-pipe, and a corresponding series of notches b in the base of the receiver. The lower ends of said lugs are disposed so the inner edge of said Tim will pass between said lugs andthe flange a and adjacent eachof the notches If is an inclined or wedge-surface Z) which is adapted to be driven beneath the lower ends of lugs u. and constitute a \\cdge-connection whereby the recciver-basin is securely held so its base will be tightly hold against the pipe-flange a." to form a tight connection thcrebetween. Usually a coating of suitable material, such as white-lead is placed on the top of the flange or the bottom of the basin to make the connection water-tight. T 0 connect the basin to the drain-pipe A it is only necessary to slip the receiver over the upper end of the pipe, with the notches If in rogistry with the ribs (1 When the basin rests on the flange a", a slight turn of the basin will cause the wedge-surfaces I) to pass beneath said ribs and then the basin will be securely connected to the drain-pipe and against displacement.

It is customary, in practice, to install the drain-pipe and receiver before the floor or quickly installed and which avoids all likeli- I hood of being displaced or disconnected when the floor, usually of concrete and cement is being laid.

The inlet-terminal o extends above the base of receiver-basin B and rcsultantly an has on theouter side of said pipe-terminal of, and in, the device, and prevent undue evaporation of the water in the trap in the drain-pipe.

The invention has several important ad-' vantages. It provides a drain and trap which may be quickly and easily connected and secured together so displacement is avoided. It provides. a device which is exceedingly simple in construction and eiiicient in operation, and one in which a supplefinental body of Water is provided to prevents evaporation of that in the trap.'

The invention is not to be understood 'as restricted to the precise details shown and described since these may be modified within the scope of the claims, without departing from the spirit and scope of the invention. 1

Having thus described the invention, what I' claim as new and desire to secure by Let ters Patent, is:

1. In a floor-drain, the combination of a drain-pipe having a trap-bend therein and an upwardly extending inlet-terminal, a re ceiver-basin having a strainer-top, a slip and interlocking wedge connection between the basin and the upwardly extending terminal of said'pipe for securing the basin around the pipe so that a water-tight joint will be formed between the pipe and the basin.

2. in a floor-drain, the combination of a. drain-pipe having a trap-bend therein and an upwardly extending inlet-terminal, a re ceiver-basin having a strainer top and a slip and interlocking wedge connection between the basin and the upwardly extending terminal of said pipe, the interlocking parts of said. pipe being on the outer side thereof and in the basin.

3. In a floor-drain, the combination of a drain-pipe having a trap-bend therein, an upwardly extending inlet'terminal, a receiver-basin having a strainer-top, an annulus on the outer side of said pipe, terminal, and a slip and interlocking connection between the basin and the upwardly extending terminal of said pipe for securing the basin so a watertight joint will be formed between theannulus and the basin.

l. In a floor-drain, the combination of a drain-pipe having a trap-bend therein, an upwardlyextending inlet-terminal, a receiver-basin having a strainer top, an annuand interlocking connection between the .basinand the upwardly extending terminal of said pipe, for seciiring the basin so a water-tight joint will be formed between the annulus and the basin.

. 5. In a floor-drain, the combination of a drain-pipe having a trap-bend therein and an upwardly extending inlet-terminal, a re ceiver-basin having a strainer-top, an integral flange on saidpipe-terminal, and a slip and interlocking connection between the basin andithe upwardly extending terminal of said pipe, for securing the base of said basin against said flange to form a water-tight connection.

6. In a floor-drain, the combination of a drain-pipe having. a trap-bend therein and an upwardly extending inlet-terminal, a re ceiver basin having a strainer top and an :opening in its bottom through which said terminal extends, and a slip and interlocking wedge connection between the basin and the upwardly extending terminal of said pipe to form a Watertight joint between the bottom of the basin and the pipe terminal.
