I Td all w-om may convent," y j Beit known that 1, CALME M.- GRAHAM, a citizen of the United States, and a resident of'larker, in the Qounty of Yuma and State' of Arizona, h ai'e invented'a new and useful Improvement in Refrigerators, ofwvliieh the tollowingfis a specification. i"

My invention is an improvement in refrigerators,` and the lnvention` has for ltsolnect to provide axrelrigerator ofthe character specified, wherein' an ice receiving chamber andv a series of food receiving chambers lare provided, so arranged that the airwill ircalate downthrough the 'ice chamber tobe the material to be 'refrigerat ed and will againpass upward to be again coolerhthus providing a contlnuons. circulation through the refrigerator and aboutihe icc and the material to. he refrigerated. i
