REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 510,273, dated December 5, 1893.

Application filed May 27, 1893- Serial o. 475,781. (No model.)

To all whoml t may concern:

- York city, in the county and State of New York, have invented a new and useful Improvement in Refrigerators, of which thefollowing is a full, clear, and exact description.

My invention is an improvement in a class of refrigerators having a siphon attachment for drawing 0E the water accumulated in a drip-pan by melting of ice. s

The invention is embodied in the construction and combination of parts hereinafter set forth. l

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar gures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the improved refrigerator, a portion of the ice compartment door being broken away. Fig. 2 is a horizontal section taken practically onthe line 2-2 of Fig. 1. Fig. 3 is a longitudinal section taken practically on the line 3-3 of Fig. 2. Fig. 4 is a horizontal section taken essentially on the linel 4-4 of Fig. 3; and Fig. 5 is a detail sectional view taken through a portion of the bottom of the refrigerator and through the drip pan and its trap.

The body of the refrigerator consists of the inner or main box A and the outer box casing B. A space 10, intervenes the inner and outer boxes, which space extends entirelyaround the in ner box, and is adapted as an air space to prevent the outside at'mospherevfrorn reducing or rendering the temperature in the inner box higher. The inner box A, is provided with double walls 11 and 12, and between the said walls a packing 13 of non-conducting material is located; in fact, the packing fills the space between the two walls, as shown in Figs. 2, 3 and 4, and while this nonconducting packing may be of any desired character, preferably it consists of felt-paper and hair felt located between layers of the paper. The ice compartment C, is located within the inner box A, at one side thereof, and the said compartment is preferably provided with a lining 14 of metal, and usually galvanized iron is employed for the purpose. The bottom or discharge section C of the ice compartment is of peculiar construction, be-

ing dished in the usual manner, as shown in Fig. 3 and provided with an opening 15, extending from one wall to the other. Achute 16, is projected downward from the bottom, the said chute connecting with the bottom at themargin of the said opening 15, as is likewise shown in Fig. 3; and the said chute is ordinarily made tapering although it may be given any other desired shape. The chute does not extend to the bottom of the refrig erator, as it terminates some distance above the'bottom, and by this means a rapid exit of the water from the ice is provided, while a perfect circulation of air may beobtained through the body of the refrigerator and Pthrough the ice compartment, thereby adding greatly to the refrigerating capacity of the box.

A drip pan 17, is located beneath the chute 16, the said drip pan being placed upon the bottom of the refrigerator. This drip pan may b e of any desired shape, or may be made of any desired material, and is capable of being readily removed when desired. The drip pan, however, is in communication with a discharge pipe 18, which is usually located in the bottom of the refrigerator, and the said drip pan is prevented from slipping Kfrom the desired position by placing in the bottom of the pan a tube 19, and causing the tube to enter the discharge pipe 18, as shown in Figs. 3 and 5. Thus it will be observed that this pan may be quickly removed from the refrigerator by simply disengagingit from the discharge pipe; and it will be further observed that the ordinary drip pipe, or pipe employed to discharge the water from the ice, is dispensedewith, and that by rendering the pan removable the bottom of the kbox may be conveniently kept clean.

In order to prevent the cold air in the box from passing out with the discharge water through the discharge pipe 18, a trap 20, is employed. Thistrapispreferablyconstructed as shown in Figs. 3 and 5, particularly in the latter figure, and comprises a Siphon or curved length of pipe, one end of which is removably placed in the exit opening of the drip pan, while the other end of the pipe is located a predetermined distance from the bottom of the pan. Thus, when .the pan has received a predetermined quantity of Water it will siphon or How out through the trap and enter the discharge pipe 18, the water at all times constituting a seal, and preventing the air from finding an exit with the Water.

In the f urthe construction of the refrigerator, the inner wall of the inner box A, is made almost entirely of Wood; preferably no metal is employed as a lining except in the ice compartment C and in the bottom, at which point a strip of metal 21, is located and secured.

The shelves 22, may be located Wherever it is found convenient within the refrigerator, and ordinarily what may be termed a corner shelf is located near the bottom, in order that a space may be provided in which to stand i tall objects, such as bottles or small kegs, upon the bottom, as shown in Fig. et.

The refrigerator may be provided with any number of doors; in the drawings a door 24, is illustrated as opening into the ice compartment C, while a second door 25, opens directlyjnto the body of the refrigerator at one side of the ice compartment; and in addition to these two doors a lower door 26, is provided.

In the construction of the refrigerator the lower wall of the lower door opening is flush with the bottom of the inner ref rigeratin g box, and this construction is preferred, as by opening the lower door 26, the bottom of the re-` frigerator maybe readily washed out, and the washing compound and material removed from the bottom, may be cleanly and conveniently carried out through the lower door opening. Ordinarily in the construction of refrigerators a ledge is formed, extending from the bottom of the refrigerator and against which the lower door closes; but this ledge materially interferes with thepropercleansin g of the said bottom.

lVhen wood is used as a lining for the refrigerator box,theinterior is not liable'to become so foul as when a metal lining 1s employed, since the cold air condensing upon the metal causes a scum to form upon the metal, which if not quickly removed becomes exceedingly offensive, but when wood 1s employed as a lining for a refrigerator box, such a scum is not formed and does notexist.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the body of the refrigerator, having a discharge-pipe extending through the bottom, of the removable drippan anda si phon trap which is removably connected with the latter and projects into said discharge-pipe, as shown and described.
