GLINE W. WARNOCK, OF BUCY 'RUS,

COMBINED TEST BATH, SAMPLE WARMER, AND HOT-WATER RESERVOIR.

Application filed May 22,

The present invention relates to improvements in hot water reservoirs and has for its directly over a fire and as a result the test bath frequently becon'iesoverheatedand as a result causes a variation in the reading of the per cent of butter-fat. And when the samples are overheated it causes an oiling off of the fat, which'also affects the accuracy of the test.

One of the important objects of the present invention is to provide a test bath which is indirectly heated whereby a uniform temperature may be maintained for the period of time during which the test tube is submerged in the'bath, and furthermore permitting the accurate reading of the per cent of butter fat. 1

Another important object of the present invention is to provide a device of the above mentioned character wherein the vapors from the hot water will be delivered into the compartment containing the cold water for assisting in the heating of the latter heforethe cold water is admitted to the hot water compartment. p

A further object is to provide a hot water reservoir of .the above mentioned character wherein an air pocket is provided for producing an insulation between the cold and hot water.

A further object is to provide a device of the above mentioned character which is simple in construction, inexpensive strong and durable and further well adapted tothe purpose for which it is designed. I

Other objects and advantages of the invention will become apparent during the course of the following description taken in connection with the accompanying drawing.

In the accompanying drawing forminga part'of this application and in which like numerals indicate like parts throughout the several views 3 Figure l is a side elevation of the combined hot water reservoir and test bath embodying my invention, with parts broken away.

the line 3+3 of Figure 1 looking in the direction ofthe arrows, and

Figure 4: is a detail perspective view otthe sample jarsupporting tray.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates a cylindrical receptacle which is open -,at its top. A hinged cover 2 is provided for the open top of said receptacle or tank. I An annular groove 3 is formed on the inner face of the cylindrical receptacle or tank l'adjacent the bottom thereof and adapted to be supported within this groove is a partition 4. In this manner, the receptacle or tank 1 is divided into an upper relatively large cold water compartment 5 and the smaller hot water compartment 6.

Communication between the cold water compartment 5 and the hot water compartment 6 is provided through the medium of the supply pipe 7. The upper end of this 7 pipe extends into the lower portion of the cold water compartment 5 while the lower or out-let end of the supply pipe 7 extends into the hot water compartment and terminates in spaced relation with respect to the bottom 8 of the receptacle or tank 1 in the manner as clearly shown in Figure 2. By

having the upper end of the supply pipe extending above the partition 4, the sediment which collects in the. upper compartm'ent wi'll be prevented from being admitted to the hot water compartment through the pipe 7.

A vapor conducting tube 9 extends up wardly in the receptacle or tank 1 through the partition 4 at a point directly opposite the supply pipe 7. The lower end of the vapor conducting pipe communicates with the hot water compartment 6 and also terminates at a point above the bottom 8. The upper end of thepipe 9 is curved downwardly as illustrated at' 10 whereby the vapors caused by the boiling of the water in the lower hot water compartment 6 will pass upwardly through the pipe 7 and will be discharged out ardly through the upper end 10 and delivered into the upper coinpartment 5 where the same comes in contact with the cold water contained therein for initially warming the same If desired, the upper end portion of the conducting pipe 9 may be braced in any suitable manner:

A; faucet of any well known construction such as is illustrated generally at 11 communicates with the upper portion of the lower hot water compartment 6 whereby the hot water in the compartment 6 may be drawn off therefrom Whenever desired.

The dead air space 12 which is formed in the lower compartment 6 between the water level in the hot water compartment and the partition 4; provides insulation between the two bodies of water and this is brought about when the water which enters the hot water compartment 6 from the cold water compartment 5 through the medium of the supply pipe 7 rises to apoint slightly above the faucet outlet.

The test bath forming a part of the present invention is designated generally by the numeral 13 and the same comprises an open top receptacle 14: arranged at the side of the 3 tank or receptacle 1 adjacent the hot water compartment 6 as is clearly shown in Figures 1 and 2. This receptacle 1 1 is adapted to be filled with water and adapted for disposition within the receptacle is the sample jar supporting tray designated generally by the numeral 15.

This tray is shown more clearly in Figure l of the drawing comprises a base 16, from one end of which extends upwardly the vertical wall 17, the upper edge of which is bent back upon itself to provide a hook 18 adapted for engagement with the upper edge of the outer side of the receptacle 1a in the manner as clearly shown in Figures 1 and 2 of the drawing. A relatively short wall 19 extends upwardly from one side of the base 16. The other end portion of the base is disposed downwardly as at 20 to provide a lip.

The tray 15 is formed of sheet metal and is of such size as to set easily within the upper portion of the receptacle 1a and when the hook 18 is disposed over the upper edge of the outer side of the receptacle, the tray will be supported in a rigid position within the receptacle and thus hold the sample jar in the water contained in said receptacle. The tray may be removed when it is desired to use all of the receptacle 1d for test tubes.

By constructing a test bath in the manner as shown and above described, the water in the bath will be indirectly heated by the hot water in the lower compartment 6 and thus a uniform temperature can be maintained within the test bath, it being understood of course that should the temperature increase beyond the predetermined point, cold water may be added. An overflow pipe 21 is associated with the receptacle 1d of the test bath 13.

The tank or receptacle "1 is placed over a fire so that the water in the compartment 6 will be directly heated and the vapors formed by the boiling of the water in the compartment 6 will be admitted to the top of the cold water compartment 5 so that the cold water will be initially heated by the vapors rising upwardly from the hot water compartment. Also, the water in the test bath will be indirectly heated. Access to the upper compartment had through the medium of the hinged cover 2. The hot water in the compartment 6 may be drawn 01f through the faucet 11.

It will thus be seen from the foregoing description, that I have provided a combined test bath, sample warmer and hot water reservoir, which is very simple in construction. A device of the above mentioned character is particularly adapted for use at cream buy ing stations, and cream tests and san'iples may be warmed in a more eliicientand positive manner than by the methods now employed. A ring such as is shown at 22 is arranged in the upper portion of the receptacle 14 for receiving a thermometer whereby the temperature of the water in the test bath may at all times be ascertained.

lVhile 1 have shown the preferred en1bodiment of my invention, it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing-from the spirit of the in vention and the scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is A water reservoir comprising a cylindrical receptacle open at its top, a hinged cover provided therefor, said receptacle having an annular groove formed therein adjacent the bottom thereof, a partition arranged in said groove for dividing the receptacle into an enlarged upper cold water compartn'ient, and a relatively small hot water compartment, a supply pipe extending through the partition for feeding the cold water to the lower compartment, the upper end of the supply pipe extending above the partition, the lower end of the supply pipe being spaced from the bottom of the receptacle, a vapor tube extending upwardly through the partition at a point diametrically opposite the supply pipe, the lower end of said vapor tube terminating in spaced relation with the bottom of the receptacle, the upper end of the vapor tube having a downwardly disposed bend formed therein whereby the vapors formed in the lower compartment will be delivered to the cold water in the upper compartment for initially warming the same, a faucet for drawing off the hot water in the lower compartment, the space between the water level in the lower compartment and said partition CLINE V.
