l DRAIN FIXTURE FOR REFRIGERATORS Filed Jan. 20, 1956 Patented Aug. 10, 1937 UNITED STATES PATENT orrlcl:

6 Claims.

This'i'nvention relates to certain new and useful improvements in drain fixtures for refrigerators z a.`nd more particularly to drain fixtures especially adapted to vbe connected to the sewerage system wherebythe water of the melting ice will be con'- Veyed from the refrigerator to the sewerage system to .overcome the diiculties of having to empty receptacles as now employed for collecting .the `water of the Vmelting ice.

Another object of my invention is to provide adrain fixture which can be readily installed in anyof the .well known makes of refrigerators now Ain useemployinga top ice compartment whereby thediculty existing of having to empty the ice drippings is overcome and a thoroughly sanitary fixture is provided whichcan be readily installed or removed to enable it to be disconnected to thoroughly clean thesame.

Another object of my invention is to provide a drain fixture with adjustable means for supporting v4a trap inthe proper position in respect to `the drain of the icecompartment whereby a liquid seal is .formed between the sewerage sys- .temandthe refrigerator. A stillfurther objectof my invention .is to pro.- v1gde .a` drain xture which is exceedingly simple andcheap in construction and yone which can vbe installedin arefrigerator so as to form an outlet througheither Ithe side or backrwall of the refrigeratQr. Otherand further objectsrand advantages of .the invention will be hereinafter `setfforth and the novel Lfeatures rthereof dei-ined` byl the appended claims.

frIn the drawing, Figure 1 is a `vertical section, partly in elevation, showing the installation of my improved construction of drain Yfixture;

.Figure 2 is a section taken Aon line 2-2 of Figure 1; '.Figure 3 is an enlarged Vertical section of a modication yshowing la slip joint between the trapand elbow; and

Figure .4 is a detail section, partly in elevation, showing the nipple ntapped into the outlet .of the sink. In'thedrawing I indicates a refrigerator and 2 the top ice compartment thereof which is provided ywith the usual drain 3 extending into the cold Lcompartment. This drain is usually connectedto a conduit which Ais provided with atrap 'and' passes out through the bottom of therefrigerator Aand underwhich is arrangeda receptacle for' catching the drippngsoftheice. IThe above descriptionis given so that the joperationof'my improved ,construction of xture when in use can `be clearly understood.

rIn carryingoutmy invention I employ ailihreadedpipe 4 .which extends througha suitable openling formed in the wall of the refrigerator and Ii lasinountedthereon nuts 5 and packing washers j in order to vforma tight joint around the .Ongoing .formed .in Athe wall .0f the refrigerator and Ato providemeans vfor adjusting the position ,of the ,pipein the wall rand locking Yit in its adjusted ,position- .After `the pipe has been forced through the opening formed inthe refrigerator, the nuts are screwed up s o asteproperly positionthe same and .lock yit lin that position.

The .pipe V4 at one end carries an elbow 1 which ris threadedonto the pipe and is provided with an internallytlrreaded portion toreceive the st em 8 of a .liquid .trap .9 which is provided with a dup shapedportion I 0 into which thel stand pipe II extends upwardly into the cup shaped portion I0 asdidient .distance t9 maintain @predetermined level `of liquid .therein- YArranged over the stand pipeV is la cap I2 which v extends which is a continuationof the stem 8 and is providedl with cut away portions I3 and this" forms a liquid sealvso as to prevent the odor from passing into the refrigerator. L

` The top ofthe cup shaped portion is open and is adapted to be sealed by a rubber 'washer I4 carried by the ldrain 3 and the upper edge is p ref-i erably vformed slightly beveled to forni a seat for the rubber washer whereby the washer will be resiliently held under tension against this seat in order to completely sealA the upper end of the cup of the trapto prevent the odors from the liquid 'standing therein Vor from air passing out ofthe refrigerator. i Y

The Aopposite end o f the pipe 4 carries an elbow I5 which is threaded onto; the end of the pipe and has a nippleportion I6 over which is adapted Atobe s lippedarubberhose I 'I ltoform a conduit for the water, the opposite end of said rubber hose Vbeing connected Vto ya A:nipple I8 of a vtrap -I9 whichis provided with a nipple 20 extending into K an opening formed in the outlet v2| of the snk22- hich is provided with theconventional liquid trap v23. A Y

Thel nipple 2 0 has a substantially semi-circular portion-24 which-is adaptedto embracethe outtionthereon by/flexible :bolts `25 extending through ..50 let pipe-2l and is adapted to' be clamped inpos-V apertured;earsand provided with nuts 21 for clamping Vthe saine, a suitable packing v28l being disposed around thevnipplefgtoxform a watertight joint as shown, and while I have shown exible bolts for clamping the same, it is, of course, un-

derstood that it can be clamped in various ways without departing from the spirit of my invention.

In the modification shown in Figure 3, the elbow 29 carried by the pipe 4 is provided with a seat 30 to receive the unthreaded stem 3| of a trap 32 in order to allow it to be lifted out of the l0 seat to clean the same, the trap being of sufcient depth so thatA the distance between the top of the cap and the end of the drain 3 is sufficient to allow the trap to be raised vertically and twisted in order to remove the same. 15 In the modification shown in'Figure 4, I show a nipple 33 tapped into a threaded opening formed in the outlet pipe 2| of the sink and the trap carried thereby is dispensed with and a flexible hose I I is connected to the nipple I3 and this provides a simple construction whereby an endless conduit can be formed from 'the trap 9 to the sewerage system above 'the liquid trap therein.

In installing a drain fixture constructed in accordance with my invention into a refrigerator, a hole is first bored through the wall of the refrigerator and the pipe 4 is slipped through the opening and the nuts and washers placed thereon. The cup shaped trap is then inserted under the drain 3 of the ice compartment and the elbow :3.0 brought into alignment with the pipe 4 and the pipe is turned so as to screw the same into the elbow, and then by adjusting the position of the pipe, -the trap can be properly positioned under the drain and by tightening the nuts on the pipe,

35 it will be locked in this position. The elbow I5 is then applied to the outer end of the pipe and Vthe nipple, which is connected to the sewerage system, is connected to the nipple of the elbow by a rubber hose so as to complete a trap tight con- 40 duit between the sewerage system and the drainage system of the refrigerator.

When it is desired to remove the trap 9 as shown in the preferred embodiment of my invention to clean the same, it is only necessary to un- 45 screw the'isame vfrom the elbow 'I and raise the lsame out of the elbow, the flexible washer allowing the trap to be raised and turned.

By removing the-hose I1 from the elbow I5, hot water can be poured down the hose I'I to 50 flush the system.`

If desired,'the. clamping means for the nipple 20 can be released in order to allow the same to be detached.

In the form shown in Figure 3, it is only necessary to lift the stem 3I'in the trap out of the elbow in order to remove the same for cleaning.

In the form shownY in Figure 4, the trap is dispensed with and a very simple construction of drain system is provided for a refrigerator.

60 While in the preferred embodiment of my invention I have shown ra trap disposed adjacent the outlet pipe of the sink, I wish it to be clearly understood that this trap can be dispensed with rand a nipple substituted therefor or that the 65 trap 9 can be dispensedwith and a connection formed between the .elbow .'I and the outlet pipe 3 of the ice box without departing from the spirit Y of my invention. Y ,v

v- From the foregoingdescription it will be seen 70 that I have provided: a 4drain fixture for a re- VVfrigerator comprising an adjustable member mounted within the wall `of a refrigerator to a1- low it to -bealigned with the outlet of the ice compartment-of the ice box and by `having a conduit 75 connected to the outlet ofthe drain above a. liquid trap, a suitable trap being disposed in the drain fixture either at the point of connection with the outlet of the sink or the outlet of the ice compartment or both whereby I am able to take care of the drainage of the refrigerator so as to overcome the difficulties existing.

It will be apparent that the top ice compartment of a refrigerator is elevated a sufficient distance to allow a free flow by gravity of water melting from the ice to the point of connection of the sewerage system.

What I claim is:

1. A drain fixture for refrigerators having a top ice compartment having a drain leading therefrom comprising an externally threaded pipe extending through the wall of the refrigerator, members threaded on said pipe at each end for adjustably securing said pipe in position therein in respect to said drain, a liquid trap supported by said pipe and disposed adjacent said ice compartment under the drain leadingtherefrom and a flexible conduit leading from the other end of said pipe having a connection with the sewerage system above the liquid trap disposed therein.
