'TO'ALL WHOM IT MAY oononnn; a

- invented a new and improved Refrigerator, which I call The Maryland Refrigerator Be it known that I, SAMUEL CHILD, of the 'cityand county of Baltimore, and'State of Maryland, have and I do hereby declare that the following is a full, clear, and exact'description of the construction and operation of the same, rcference being had to the annexed drawings, making a part of this specification, inwhich 1 v Figure 1 is a vertical section, through the liney y of fig. 2.

Figure .3 is a cross-section, through the line a: a: offig. 1. i v v This improved refrigeratonisso constructed that the meltings of the ice are retained a position where theycan be used to absorb the gases, vapors, or odorous matters that are given oil from the viands, while the ice-cold water, as it becomes charged with these offensive matters, is passed out of the refrigerator without allowing entrance to tbc'cxternal air, and without permitting any air-currentsto; .pass in contact with the ice either over or under it.

A good refrigerator mustbe capable of mai'n'tiiini'ng'fin itsinfteriorarempcratnrelow-enough-t ozpneseweh the articles placed therein. It must accomplish this economically, with the 'least possible consumption ofice; and, most important of all, it must always exhibit a perfectly dry and pure atmosphere. If, with these requisites, it is self-purifying, so that no accumulation of disagreeable odors can possibly occur-,it is evidently exactly what is wanted. These indispensable conditions are believed to be more perfectly accomplished by this Maryland refrigerator" than by any other invention fcr the purpose yet known.

The introduction or passage of external air through a refrigerator creates moisture and dampness, and robs it of its colder atmosphere, and causes an unnecessary waste of ice. Currents'produced withina refriger-' ator, by passing the warmer atmosphere over and upon the ice, are greatly objectionable, causing a great consumption of ice, and always leaving an extremely had odor in the ice-chamber, so much so that water placed therein cannot be drank, as these who have bought such refrigerators have no .doubt' discovered. For the purification of ai -refrigerator, disinfectants cannot be used, but an absorbentcan. This we have self-supplied, and renewed and changed, as used in the Maryland refrigerator. i i

The principle of this refrigerator may be described asfollows: The air leaves the. ice-chamber at a temperature as near as practicable to 32, descends by its own gravity to the lower partsof the preserving-chamber, and the warmer atmosphere rises towards the upprpar'ts of the refrigerator, and in its passage comes in contact with the cold Water formed by the melting of .the ice, and contained in an open vessel. By such contact with I i-,his cold water the moisture of the air is condensed, it becomes dried, and at the same time the odors and vapors present are absorbed and passed out of the refrigerator-by means of the wastewater. This process is continued so long as the refrigerator contains any ice. Hence, by retaining the meltings of the ice in a vessel of a particular construction, which is self-discharging, and placed in a, proper position, wli are enabled to purify a refrigerator more perfectly and with a less quantity of ice'thjan hascver before been accomplished.

It must be borne in mind that, since .cold water is an absorbent of gases and vapors to a definite, an d therefore it limited, extent, this power is useless unless, as n the invention which I claim, a provision is made for discharging the water already saturated with ofi'ensive matters, and for maintaining a constant new supply of pure cold water. i A

-In the drawings, A. represents the ice-chamber, having an inclined bottom, a, which discharges the water formed from melting the ice upon a gutter, I having a dischargc -orifice, b, whence it flows into a-ivatercondensing pan, C, from which. after rising to a certain height, it escapes through a waste-pipe, D. B is a partition, which separates the ice-chamber from the chamber above the water in the pan C. E E are the walls, F the cover, and G the bottom of the refrigerator. I

The ice is placed in the chamber A, and the food or other article to be cooled is placed on suitable shelves -6! in vessels, in the preserving-chamber II. As the air in the ice-chamber is cooled, it descends to tho preservingchamber, and keeps the food in a suitable condition for use. The-water formed by the'melting of the ice accuice-chamber A, and gutter B as herein described, for the purpose specified.

mulates in the pan 0, where it absorbs the gases,'odors, &e., that rise from the food, and flows off through ori-fi'ce of pipe D, carrying with it the oflensive matters referred to.

It will be observed that the pan 0 occupies a very small portion of the refrigerator, so that the gases and v odors passing upward from-the provision-chamber are uuohstruoted. They therefore cannot becondensed against the bottom of the pan C,but are directed at once to the upper portion of the refrigerator and absorbed by the water in the pan.

The whole operation of ;the refrigerator is therefore exactly that which I have above described, combining all the essential requisites (if a refrigerator especially adapted to the preservation of food and other articles whigh emit gases or disagreeable odors. i v

' Having thus described lily invention, what I claimas new, anddesire to secure by Letters Patent, is-

The arrangement of pan 0, having the waste-pipe D, with relation to the provision-chamber H, the
