Patented Feb. 23, 1937 UNITED STATES PATENT OFFICE Claims.
My invention relates to improvements in Water purifying and cooling systems and like devices.
My invention relates more particularly to an improved water purifying and cooling system for homes, oflices, restaurants, apartment buildings and many other places, and has for its purpose the provision of a simple cooling apparatus and water outlet whereby the ordinary hydrant water may be directed through a cooling device associated with an ordinary refrigerator and returned to a faucet at the sink.
An object of my invention is to provide an improved apparatus of the class described that will be easily and simply constructed and which may be installed by an ordinary unskilled workman.
A further object of my invention is to provide an improved construction of faucet arrange ment whereby a special cold drinking water faucet may be placed at a point adjacent the usual hot and cold water faucets in a sink.
A further object is to provide a simple and effective circulating system from the above mentioned faucet to a refrigerator and back.
A further object is to provide an improved cooling and circulating apparatus easily and quickly installed in the ordinary refrigerator.
.A further object is to provide an improved faucet construction having a third faucet for cooled drinking water.
The purpose of my improved water cooling system is to provide practical and permanent means for drawing cold water for drinking purposes at the kitchen sink or similar modern sanitary .fixture, all in harmony with the practicability and appearance of these fixtures. Thus, I will be able to eliminate the use of ice cubes for cooling drinking water, which have a special use, but which do not solve the problem of a permanent and ready drinking Water provision for home and omce use.
My improved water cooling system solves the major problem of electric refrigeration in that it is capable of cooling the drinking water by the use of a minimum amount of energy and the provision of a drinking water which is of a temperature that is most desirable for drinking purposes.
All these and other objects and advantages of my invention will be more apparent from the following description wherein reference may be had to the accompanying two sheets of drawings upon Which Fig. 1 is a diagrammatic view in perspective of a cooling and purifying system embodying my invention;
Fig. 2 is a similar diagrammatic view in perspective of a system which does not employ a purifying unit;
Fig. 3 is a sectional View showing a special plug which I employ with my apparatus;
Fig. 4 is a plan sectional view of a special fitting which I employ with the form of my invention shown in Fig. 2; i
Fig. 5 is a vertical sectional view taken on the lines 55 of Fig. 4; and
Fig. 6 is a fragmentary view showing the installation of the cooling apparatus in a refrigerator.
In the embodiment of the invention shown in Fig. 1, the regular service pipes l0 and I2, used in the home or office building, may extend through the wall at the sink or any other desirable location and be associated with the outlet faucet arrangement I wherein a valve member I6 controls the flow of the hot water and a valve member I8 controls the flow of the cold water to a suitable spout member 20.
The cold water inlet line l2 may enter a fitting 29 interposed between the valve l8 and the inlet to the line l2. The fitting 2!! together with the upright pipe members 22 and 24,. base member 26, and filter F may be constructed in accordance with the disclosure of my Patent No. 1,896,310, issued on February '7, 1933, which discloses in detail the construction of the fitting 20 and the purpose and arrangement of the parts associated therewith. The base 26, however, may be modified to include a third valve and faucet member 28 which, as will be further explained, Will be the outlet for the filtered, cooled Water.
In accordance with this construction, a pair of pipe lines 30 and 32 may extend outwardly from the member 26, the pipe line 30 entering the lower end of a vertical standpipe 34, and the pipe line 32 entering the lower end of a vertical standpipe 36. The vertical standpipes may be joined at their upper end by a suitable conduit 38 so that a continuous passageway is formed from the base member 26 through pipe line 30, standpipe 34, conduit 38, standpipe 36 andreturn pipe line 32.
In Fig. 2, substantially the same system is illustrated except that in this showing of the invention the filter F has been eliminated and the base member 26 thereof has been modified to include a receptacle holder 40 for a drinking glass 42 or similar object.
In Fig. 4, I have illustrated in cross-section the details of construction of the base member 26 as shown in Fig. 2, it being understood that the base membershown in Fig. 1 will be similar to the device shown in Fig. 4, except for those changes embodied in constructing the connection with the filter, which is clearly explained in my issued patent previously mentioned.
The base member may be formed with a passageway 44 extending outwardly upon one side thereof and terminating in a housing portion 46 having a forwardly extending boss 48 to which the valve member 28 may be rigidly connected. The back wall 59 of the housing 46 may have a pair of tapped openings 52 and 55 therein within which a pair of coupling members 56 and 58 are mounted. The members 56 and 58 may be formed with a socket 60 within which pipe lines 3!] and 32 are adapted to terminate. A cap nut member 62 may enclose a suitable gasket member 64 which is adapted to be fastened down over the end of the pipe line so that a rigid joint may be formed between the coupling members 56 and 58 and the pipe lines and 32.
The coupling members have a suitable passageway therein which communicates with the interior of housing 46. The interior of the housing 46 may be separated into two chambers by a wall member 68 which is formed with a vertical bore 10. A valve member 12 is adapted to be rotatably mounted in the bore 18 to establish com munication between the two chambers formed by means of a slot 14 formed in the valve member E2.
The valve 12 may have a handle portion 16 which has the word Cold written thereon and which is adapted to be so constructed that when the valve is turned in the direction shown in Fig. 5, the communication between the two chambers will be effectively closed and water entering through the lines 22 and 24 must flow through the pipe line 3!) and cooling standpipes 34 and 36 before it is returned to the housing 45 to be expelled through the valve 28.
The standpipes 34 and 36 may be of any desirable construction embodying a funnel-shaped lower portion 80 and. an upper funnel-shaped portion 82. The purpose of this construction is to eliminate the possibility of any sediment lodging therein and to keep the entire body of water contained in the standpipe circulating from bottom to top and from top to bottom to produce the greatest coolness for the minimum amount of refrigerating energy expended. Thus to prevent sedimentation and to produce an even flow through the standpipes they are provided with the comically-shaped inlet and outlets described.
The fact that the standpipes are vertically positioned in the refrigerator is desirable because it ensures constant movement of the water by reason of the difference in the temperature at different times and in the different parts of the refrigerator, the warmer water constantly seeking the upper part of the standpipe and the cooler water descending. This motion is due partly to the temperature within the refrigerator and, of course, is also due to the inflow of warmer water through the bottom of the refrigerator and the mixing of the colder Water contained in the standpipes.
It is preferable to use standpipes in pairs, not only to produce the intensest cooling but also to keep on hand a sufficient supply of water for drinking as well as to provide for outlet at the bottom of the refrigerator near the inlet, whereby both inlet and outlet are positioned so close together that the installation or removal of the standpipes is efficiently and expeditiously accomplished. It is of course possible to provide three or four, or more standpipes, depending upon the amount of cooled water desired; but in carrying out my invention I prefer to provide the standpipes in pairs due to the convenience in assembling and constructing them in this manner in the refrigerator.
In Fig. 3, I have illustrated a special plug, the purpose of which is to close up outlets through the couplers 55, or to close the outlets at the connections 83 and 85 to the cooling standpipes. This plug 81 may be of the same diameter as the pipe lines 36 and 32 and thus it is a simple matter to insert the same in the socket 60 of the coupler and screw down the connecting nut 62 to force the gasket 64 against the wall of the plug 81, thus positively ensuring a leakproof joint. By the use of these plugs, it is a simple matter to install or remove a water cooling system of the type described. It is further simple to remove the standpipes or to remove any desired pipe connections when it is necessary to clean or repair the apparatus.
By the provision of the valve member 12, it is believed to be obvious that when it is not desired to cool the water but rather only to filter the same, the circulation of the water through the standpipes can be effectively prevented by the opening of the valve 12. The closing of the valve will again result in the directing of the water flow through the standpipes for cooling purposes.
While I have illustrated and described the invention with special reference to a construction wherein a cooling unit containing only two standpipes is shown, it is of course understood that as many may be employed as desired. I do not wish to be limited to any of the detailed constructions shown; rather what I desire to secure and protect by Letters Patent of the United States is:
