FLOOR DRAIN FLUSHING DEVICE Filed Aug. 10, 1956 IN VEN TOR.

United States Patent C) FLOOR DRAIN FLUSHING DEVICE David Fleischman, Detroit, Mich.

Application August 10, 1956, Serial No. 603,287

1 Claim. (c1. 137 -240 This invention relates to plumbing fixtures and, in particular, to floor drain flushing devices.

One object of this invention is to provide a floor drain flushing device which enables an ordinary garden hose to be attached to a basement faucet and used for the quick and easy flushing of clogged or partially clogged floor drains, such as are used in basement floors, in order to clear obstructions therein and bring about the free flow and drainage of liquid in the basement.

Another object is to provide a floor drain flushing device which is simple in construction and low in cost of manufacture and subsequent cost to the consumer, either in the form of a complete floor drain fixture equipped with the flushing device or of a flushing device adapted to be installed in a standard floor drain in a rapid and easy manner.

Other objects and advantages of the invention will become apparent during the course of the following description of the accompanying drawings, wherein:

Figure 1 is a side elevation, partly in central vertical section, of a floor drain flushing device, according to one form of the present invention, with an ordinary garden hose coupled thereto for flushing the drain;

Figure 2 is an enlarged central vertical section through the floor drain flushing device shown in Figure 1;

Figure 3 is a top plan view of the floor drain flushing device shown in Figure 2; and

Figure 4 is a fragmentary central vertical section of the upper end portion of a modified floor drain flushing device for installation in a standard or conventional floor drain fixture.

Referring to the drawing in detail, Figures 1 and 2 show a floor drain fixture, generally designated 10, of special construction and especially adapted for use with the present invention, in that it has an annular threaded recess 12 extending inwardly from the downwardly-converging entrance portion 14, to the vertical lower portion 16, the internal recess 12 being shouldered as at 18. The entrance portion 14 is seated in the concrete floor 20 at the floor level 22 and has a rim 24 with a stepped recess, socket or rabbet 26 which normally receives a slotted drain plate or disc which has been here removed.

The invention consists of a tubular plug 28 having an external threaded portion 30 threaded into the threaded bore 12 against the shoulder 18, a hexagonal portion 32 for the application of a wrench, and an internallythreaded bore 34 into which the externally-threaded lower end portion 36 of a hose connection pipe fitting 38 is threaded, the upper externally-threaded end portion 39 of which is adapted to receive a coupling 40 of an ordinary garden hose 41, the opposite end of which is connected to a faucet in the set tubs.

The modification generally designated 42 shown in Figure 4 provides an externally-unthreaded cylindrical adapter sleeve 44 having a smooth bore 46 together with an enlarged internally-threaded counterbore 48 with a shoulder 49 therebetween serving as an annular abutment for a tubular screw plug 28 which, as in Figures 2 and 3, has an externally-threaded portion 30 and an internallythreaded bore 34. The latter in turn receives the externally-threaded lower end portion 36 of the hose connection pipe 38, as before. The sleeve 44 is necessary because the ordinary floor drain fixture 50 has a straight smooth bore 52 therein without the internally-threaded recess 12 and shoulder 18 of the special floor drain fixture 10. The fixtures 10 and 50 are ordinarily made of cast iron. The floor drain fixture 50 has an enlarged flared catch basin portion at its upper end like the portion 14 of the fixture 10. In order to provide a connection for the plug 28 and hose connection pipe 38, the sleeve 42, which is preferably of aluminum or other non-corrosive material, is inserted in the bore 52 and cemented therein as by the use of a layer 54 of so-called iron cemen An internally-threaded tapered nozzle 56 is optionally threaded onto the lower portion 36 of the hose connection pipe 38.

To use the device, the plug 28 and connection pipe 38 are inserted as shown in Figure 1 or Figure 4 and a garden hose connected to the threaded portion 40 and to a faucet. The pressure is turned on and the hose flushes out the fixture 10 and the drain pipe 58 connected thereto.

What I claim is:

A floor drain flushing device adapted to be installed in the bore of a conventional tubular floor drain fixture, comprising an adapter sleeve having a substantially cylindrical external surface configured to fit loosely into said drain fixture bore and receive an intervening layer of conventional securing cement therebetween, said adapter sleeve having a bore therethrough and an internallythreaded counterbore at the upper end of said sleeve bore with an annular abutment shoulder therebetween, an externally-threaded plug threaded into said counterbore against said abutment shoulder and having a wrench-receiving portion on its upper end, said plug having an internally-threaded bore therethrough, and an upstanding tubular hose connection fitting having an externallythreaded lower end portion threaded into said internallythreaded bore of said plug, said fitting extending upwardly from said plug and having a threaded upper end portion adapted to threadedly receive the oppositely-threaded hose coupling of a conventional garden hose.
