REFRIGERATOR DRAIN.

My invention relates to improvements in draining means for refrigerators and the like. It is particularly designed to provlde a drain for tubular receptacles which are ada ted to contain liquid.

y invention is especially adapted for use in connection with that type of bottle cooling refrigerator wherein the bottles are passed through substantially U shaped tubular channels for cooling purposes. In this type of refrigerator there is usually provided an outer corrugated tub and an inner corrugating tub nesting the outer tub, the walls of the two tubs being spaced apart to form substantially tubular channels through which the bottles to be cooled are adapted to be passed. The space between the channels is adapted to be filled with a cooling liquid and the inner tub is adapted to contain ice or other refrigerating medium. The drain of my invention is especially applicable to this type of refrigerator as it permits of the normal draining of the inner tub when the water therein attains a predetermined level and at the same time permits of the comlete draining of both compartments when esired.

For the pur ose of disclosing my invention I have illustrated one 'embodiment thereof in the accompanying drawings in which Fig. 1 is a. perspective view partial] in section of a type 0 refrigerator with which my invention may be used;

Fig. 2 is a detail section of a part of the refrigerator and of the drain, and Fig. 3 is a detail partial sectional view showing the drain opened for complete drainage. V

The refrigerator of the type illustrated comprises a suitable receptacle or casing 1 in which is mounted a corru ated tub 2 U shaped in cross section, a. suitable filler of insulating material being interposed between the tub and the walls of the casing. Suitably supported in nesting position and spaced apart from the tub 2 is an inner corrugated tub 3 substantially U shaped in cross section. This arrangement rovides a series of water communicating tu ular channels 4 through which the bottles to be cooled may ass. Both tubs are open at their tops. oors such as 5 are provided for closing the openings to the channels 4 and a cover plate such as 6 is provided for covering the Application filed March 11, 1926. Serial No. 93,903.

inner tub. This inner tub chamber 7.

For drainage purposes the outer tub 2 is provided with an opening 8 through which projects .a drainage tube 9 the upper end of which lies adjacent to the inner tub 3 immediately beneath an opening 10 therein. The tube 9 is provided with an annular flange 11 on which the bottom of the outer tub 2 seats and has an extended nipple 12 interiorly screw threaded for connection with a. drain pipe or suitable drain cock 13. This tube 9 is provided in its sides with drain openings 14 which communicate with the space between the outer and inner tubs. The upper end of the tube 9 preferably has a permanent connection with the bottom of the inner tub 3 and at the annular flange 11 with the bottom of the outer tub 2. This arran ment provides for a drain communicating both with the chamber 7 in the inner tub 3 and with the chamber 4 between the outer and inner tubs 2 and 3.

In normal use of the refrigerator the water in the chambers or tubes 4 is maintained therein. The ice is placed in the inner chamber 7 and as the ice melts it is desirable to have some means for drainin the water from this chamber after it reac es a predetermined level. To this end I provide a drain pipe 15 which projects into the drain tube 9 and has a screw threaded end 16 taking into the internal screw threads 17 in the lower end of the tube 9. This drain pipe 15.has an annular collar or flange 18 backed by a. collar 19 which flange 18 bears on the inner surface of the inner tub 3 so that when the pipe 15 is screwed down into the tube 9 the inner tub is clamped between the top of the tube 9 and the flange 18. Drain openings 20 are formed at a predetermined point near the top of the drain pipe 15 throu h which the water from the melting ice of t e chamber 7 drains and above these openings there is also provided openings 21 into which a turning pin may be inserted for rotating the pi to screw it into and out of its socket. It will be noted that this arrangement provides provides an ice a means for normally draining the inner tub and at the same time when it is desired to empty both the inner tub and the space be- 4 tween the inner and outer tubs it is merely necessary to remove the pipe 15 when the water will flow through the drain tube 9 from both chambers.

I claim as my invention:

1. The combination with a pair of nested tubs each arranged to contain liquid, a drainage tube connected with the bottom of the inner tub and arranged to extend through the bottom of the outer tub and having openings communicatin with the outer tub a second drainage tu telescoping said first mentioned tube, and removably threaded therein to close said first mentioned tube and arranged to extend upwardly into the inner' tub for drainin the inner tub and having means for closing the drainage connection of the first tube with the inner 2. The combination with a pair of nested tube each adapted to contain liquid, of a draina tube projecting through the outer tub an having its inner end bearing on the inner tub, an annular flange on said tube on gthe outer tub, a second drainage tu telescopically screw threaded into said first mentioned tube and projecting into the inner tub and an annular flange on said tube bearin u n the inner surface of the inner tub w are when said tube is in position the wall of the inner tub will be clamped between the end of the first mentioned tube and the collar on said second mentioned tube.

3. The combination with a plurality of nested tube, of a drain therefor comprising a draining tube having a drainage connection with the bottoms of each of said tubs, of an overflow drain tube associated with said first mentioned tube, said overflow tube co-operating with the first mentioned tube when in drainage position to establish an overflow passage from'the inner tub and to close the drainage connections of the first 4t mentioned tube with both tubs, and movable to a position to simultaneously establish drainage connection between both tubs and said first tube.

4. The combination with a pluralitypf nested tubs, of a drain tube common to all tive tubs, said drainage tube being movable to a position to establish simultaneous 55 drainage communication between the first tube and both-tubs.

5. The combination with a plurality of nested tubs, of a drainage tube common to all of the tubs and having'a drainage connection with each of the tubs, of a'second drainage tube telescopically insertable in said first draina' e tube and having means for closing the rainage connections of the first mentioned tubes with each of the tubs and for establishing an independent drainage connection for the inner tub, said second mentioned tube being removable from position to permit the drainage of both tubs through said first mentioned tube.

In witness whereof I, CHESTER A. FmcK, have hereunto set my hand'at Indianapolis, Indiana, this 5th day of March, 'A. D. one thousand nine hundred and twenty-six.
