LONG BEACH, CALIFORNIA Application filed January 2?, 1931. Serial No. 511,596.

This invention relates to apparatus for testing petroleum products, and vcontemplates a structure embodying mechanical refrigeration as a cooling medium, so that tests can be more accurately and quickly conducted.

in carrying out the invent-ion I also comprehend an apparatus for the above-men tioned purpose, including retrigerating compartments in which receptacles containing the product to be tested, are adapted to be positioned to be properly cooled for cold pour tests, and a cold storage compartment receiving the refrigerating 115 and cooled thereby.

The nature and advantages of the invention will be better understood when the i'ollowing detailed description is read in con-' nection with the accompanying drawings,'the

invention residing in the construction, combination and arrangement of parts as claimed.

In the drawings forming part of this application lire numerals of reference indi- 5 cute similar parts the several views and wherein:

Figure l ratus.

Figure 2 is a sectional view on line 2-2 9 of Figure 1.

re 3 is a top plan view; ure a is a sectional view on of Figure 3. I

The apparatus forming the subject matis a rear elevation of the appaline 4- 4 ter of the present invention is in the nature of a cabinet, which of course can be constructed from any suitable material and also vary in size and configuration without departing from the inventive idea. The

" main body portion of the cabinet isindicated at 10, and provides a cold storage compartment to be hereinafter referred to, the cabinet including a top 11 upon which is arranged a plurality of heat chambers 12.

v These chambers 12 are arranged side by side and extend longitudinally of the cabinet as clearly illustrated in Figure 3, each heating chamber having air openings 13 and a door 14:. Located within each chamber 12 is a heater 15 of any suitable character, each comp artments preferably including a valve 16 actuated by a valve operating rod 17 so that the prodnot to be tested can be distilled at a uniform rate by regulating the flame ofthe heater. Of course an electrical heater may be also employed without departing from the spirit of the invention.

Located within each heating chamber 12 a dash 18, preferably an Engler flask which is supported upon an asbestos board 19 hav ing' a cental opening therein over which the flaslarranged clearly illustrated in Fig ure 2. The fiasl: projects through an opening in the top of the heating chamber, and

has associated therewith a thermometer 20.

The flask 18 is of course adapted to receive a predtermined quantity of the product to be tested, and the particular quantity of said productis measured in a suitable graduated receptacle ill and subsequently poured therefrom into the flask 18. After the predetermined quantity of the product has been trans- I contemplate the provision of mechanical i refrigeration as a cooling medium, so that the tests can be more accurately and quickly conducted. Consequently, I provide a re-- trigerating compartment 23 which is copperlined as indicated at 2% and this refrigeratin compartment is arranged at one side of the heating chambers 12, substantially, coextensive in. length with t 1e cabinet, and common to all'ofthe flasks 18. In other words, the con 7 iser tube 22 from each flask passes through the refrigeration compartment 28 in the manillustrated in Figure 2, while arranged within the r iigerating compartment are cooling coils 25 positioned above and below the condenser tube 22. The refrigerating compartment 23 is adapted to receive a water bath, which completely surrounds the condenser tubes 22, and the water is maintained in continuous circulation by an agitator 26 which is operated by means of a suitable motor 27. More than one of these agitators may be employed if so desired. Also rising from the top of the refrigerating compartment 23 are spaced standards :27, one for each thermometer 20, and adjustably supported upon each standard is a magnifying glass 28 to facilitate reading of the thermometer when necessary.

In practice, a 1n edetermined quantity of the product to be tested is first measured in the receptacle 21, and subsequently poured therefrom into the lasks 18. The refrigerating compartment 23 is then filled with water, and the graduated receptacle arranged upon thecabinet in position to receive the outlet end of the condenser tube 22. It is of course to be understood that there one of these graduated receptacles 21 used in conjunction with each flask 1S and each tube Heat is then applied at a uniform rate. to the flasks l8 and the condensate then starts to fall'from the tubes 2 into the receptacle 21. lVhen the first drop falls from the end of the. condenser tubes 22 into the adjacent receptacle 21, the reading of t 1e distillation thern'iometer 20 shall be recorded as the initial boiling point. The heat shall then be so regulated that the distillation will proceed at a uniform rate, and the reading of the distillation thermometer shall be observed and recorded when the level of the distillate reaches each 10 cc. mark on the graduated receptacle 21. The heating shall'be continued until the mercury reaches a maximum and starts to fall consistently. The high-est temperature observed on the distillation thermometer shall be recorded as the maximum temperature, and usually this point will be reached after the bottom of the flask has become dry. The total volume of tl e distillate collected in the graduated receptacle shall be recorded as the recovery. The cooled residue shall then be poured from the flask into a small cylinder graduated in 0.1 cc., measured when cool, and the volume recorded as residue. The difference between cc. and the sum of'the recovery and the residue shall be calculated and recorded distillation loss. It has been found that by providing mechanical refrigeration in an apparatusof the class in question, that tests of this character can be more accuratelyand quickly conducted and that thecondenser tubes 22 are always subjected to and maintained at an even temperature.

As hereinabove stated, the body of the cabinet provides acold storage compartment in- I dicated generally at 29, ad which compartment is provided with doors 30 and drawers 31. Located within the storage compartment 29 is a plurality of refrigerating compartment-s 31', 32 ant 33, the former preferably including a plurality of copper containers 34, each having wound thereabout a heat absorbing coil 35, and each container adapted to individually receive a receptacle containing the product to be tested. The other refrigerating compartments 32 and 33 respectively are preferably in the nature of copper tanks adapted to receive a water bath or other cooling agent, while each tank is also surrounded by heat absorbing coils 36. It will be noted that these refrigerating compartments are arranged within the cold storage compartment 29, and thereby serves to maintain the latter at a proper temperature for the purpose intended. Also, arranged beneath the refrigerating compartments is a drain pan 3? for draining oil the moisture brought on by dcfrosting of the cooling coils as will be readily understood. it is of course to be understood, that sample bottles of oils or other petroleum products are adaptedto be inserted in the latter mentioned refrigerating compartment to be cooled for making cold pour tests, and tiese compartments are maintained below zero Fahrenheit temperatures. Manifestly, I have devised an apparatus wherein petroleun'i products or the like can be quickly, conveniently and accurately tested, and while I have illustrated and described what I consider the preferred emhodiment of the invention, I desire to have it understood that I do not limit myself to what is herein illustrated, and that as fall within the scope of what is claimed.
