rnsrccaron AND COOLER.

Specification of Letters Patent.

Patented Apr. 9 1918.

Application filed May 20, 1916. Serial No. 98,758.

To izllwhom it may concern:

Be it known that 1, Jones JOHN MOJON- NIER, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Desiccators and Coolers, of which the following is a specification.

This-invention relates to desiccators and coolers of the type adapted to not only act as a cooler for heated material but also to thoroughly dry the material during the cooling thereof. It is the object of the present invention to present a large radiating or cooling surface to the vessel containing the material in such a manner that said vessel-rests flush, at all points, with the cooling or radiating surface. In this manner the material within the vessel is brought to a temperature corresponding to that surrounding the exterior of the desiccator and cooler.

Furthermore, the vessel when within the desiccator or cooler may be, if desired, in

. close proximity to a large quantity of absorbent material, whereby the material may be simultaneously dried.

, With the above and other objects in view, as will be apparent, this invention consists in the construction, combination and arrangement of parts, all as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein Figure 1 is an elevation of a desiccator and cooler constructed in accordance with the present invention;

Fig. 2 is a plan view thereof with the cover removed;

Fig. 3 is a vert1cal section taken along line 3-3 of Fig. 2, with the cover in position and illustrating a vessel located in the desiccator andcooler;

Fig. 4 is a view, similar to Fig. 3,'of a modified form of the present invention, and illustrates the same provided with a series of auxiliary vessel pockets, and

Fig. 5 is a horizontal section along line 5-5 of Fig. 4:.

The present desiccator and cooler comprises two parts or elements, viz.,-the body or receptacle l3 and the cover or lid O therefor. The former comprises a circular metallic receptacle 10, supported by a series of legs 11 in such a manner that free circulation is provided under the receptacle.

An outstanding horizontal flange 12 projects peripherally from the edge of the wall of the receptacle 10 and constitutes a support for the cover C in a manner to be hereinafter more fully described. Interiorly, the receptacle 10 is divided into the outer and inner compartments 13 and 14:, respectively, .by the partition 15 concentrically positioned with respect to the wall of said receptacle and extending vertically from the bottom thereof to a plane somewhat below the plane of the edge of said wall. The outer compartment 13 is to receive an absorbent (indicated in Figs. 2 and 3), such as calcium chlorid; while the inner compartment 14 is designed to receive a dish 16, in which is contained the material to be cooled and dried.

,By reference to Fig. 3, it becomes apparent that this disk 16 contacts at all points with the inner side of the partition 15 and the bottom of the compartment 14, which is also the bottom of the receptacle 10, and has-a snug, flush fit within the compartment 14. In this manner, the heat of the dish 16 and its contents is transmitted to the partition 15 and the bottom of the compartment 14, until the dish and its contents have a temperature equal to that of the atmosphere surrounding the desiccator or cooler. lhe supported position of the body B, by reason of the provision of the legs 11, per mits of a free radiating surface under said body, thus increasing the elticiency of the device by enlarging the radiating area and decreasing the time heretofore consumed in the cooling operation. During the cooling, the absorbent within the compartment 13 removes all moisture from the air within the cooler and desiccator, and hence when the cooling is complete the contents of the dish 16 are perfectly dry.

The lid or cover C of the desiccator and cooler comprises a somewhat conical plate 17, having the solid stud or protuberance 18 at the apex thereof, and the depending cylindrical flange 19 at the base thereof, said flange terminating in the outstanding peripheral flange 20. In operation, the lid or cover C is so placed on the body or receptacle B that the flange 20 of the former coincides with and rests upon the flange 12 of the latter, the weight of the said cover being suflicient to maintain a flush contact between the two. By the provision of the .22extending from the partition 15- to the wall of the receptacle v10. Each pair of these partitions 22 form, in combination,

a pocket 21 located between two bodies of absorbent material, so that the. contents of vessels placed in the pockets 21 are readily and quickly cooled and dried. Furthermore, vessels such as crucibles placed in the pockets 21 contact with the walls of the pockets and are hence brought to the temperaature of the atmosphere surrounding the desiccator, as in the case of the dish 16.

'It hasbeen found by experiment that many agents may be used in the compartment 13 for the purpose of drying the contents of the compartment 14: or of the pockets 21; among which are calcium chlorid and potassium hydroxid. In addition to these agents, sulfuric acid has been found to be a suitable absorbent, although when so used. it is necessary to line the compartment 13, or the divisions thereof created by the pockets 21, with lead to prevent the acid from acting upon the metal of which the desiccator and cooler is formed.

1 claim: I 1

l. A desiccator and cooler comprising a receptacle, a partition dividing said receplegs supporting said receptacle.

2. A desiccatorcomprising a receptacle, a partition within said receptacle forming a dish-receiving compartment, and a surrounding compartment, the bottoms of said compartments being in the same plane.

3. A cooler constructed of heat-conducting material and provided with a large radiating surface the majority of which is V tacle into a plurality of compartments, and

free, and having a relatively shallow dishreceiving compartment so arrangedthat a dish set in said compartment may contact with the radiating surface aforesaid.

a. A desiccator and cooler constructed of heat-conducting material provided with a large free radiating surface,'and having a dish-receiving compartment the w'allwhere of is wholly surrounded throughout by an absorbent receiving compartment so arranged that a dish set in said dish-receiving compartment may contact throughout with the radiating surface aforesaid.

5. A desiccator or cooler comprising a relatively shallow receptacle supported by legs whereby the bottom of said receptacle is exposed, and having a dish-receiving compartment therein so arranged that a dish set in said compartment may contact throughout with the bottom of said receptacle.

6. A desiccator and cooler having a central dislrieceiving compartment surrounded by a compartment for an absorbent of moisture, the bottoms of said compartments being in the same plane.

7. A desiccator. and cooler including a central dish-receiving compartment having a large radiating surface to rest flush against the dish received therein, and having its wall wholly surrounded by a compartment for a moisture absorbent.

8. A desiccator and cooler comprising a central dish-receiving compartment surrounded by a compartment for an absorbent of moisture, the latter being divided to form auxiliary receptacle receiving compartments.

9. A desiccator or cooler comprising a vessel-receiving compartment in conjunction with a compartment for the reception of a moisture absorbent, the latter containing a series of cooperating partitions each pair of which forms an auxiliary vessel-receiving pocket.

10. A desiccator and cooler comprising a vessel-receiving compartment in conjunction with a compartment for a moisture absorbent all formed integrally with their bottomsin the same plane.
