'IMPRovi-:MENT 1N REFRIGERAroRs.

The Schedule referred ta'in these Letters Patent and making part: of the same.

To all persons to fw/tom these presents may camel' -Be it known that I, ANDREW JACKSON CHASE, of Boston, of the county of Suffolk and State ot Massay "chnsetts, have inventedV an Improved Refrigerator; p and do hereby declare the same-to be fully described inthe following specification and represented in the accompanying drawing, ofg'yvhichmv Figure l is-a transverse section, andA Figure 2 a long'udinal section of it.

In such drawing--- y j A' denotes a box, having an opening,` a, at its top,

and another, b,'in vits side, such openings being furnished' with covers or doors, c d, for closing them.

In carryingrou't my invention I arrange within the i said box, directly against one side oi' it, and at or near the upper part ot' such. sido', an inclined apron, D, which l' usually make of sheet inetal, the inclina. tion of the apron causing it to stand at anacutefangle with` `the next Vadjaceutside of'. the box, such being'- as shown in tig. 1. VThe apron extends entirely across .the interiorof the box, from one to the other of the ends of it. .Y

` At itslower end the' said apron terminates against another short inclined apron, F, arranged at or about Aat a right angle with Athe iirst one.

- `Underneath the junction ot' the two aprons is 'a trough, H, which extends across the box from end'to l y end, and has a duct leading through one end.

At the junctiony ot' the' two aprons, or directly over the trough,vthere sl'iouldlbe made, in eitherapron or in both, one o r more holes forv discharge of water into the' trough, which trl'mgh should be open at top, and be` arranged with referencetolthe lower sides of the two aprons, in manner as represented, in order 'that any vapprfthat maybefcondensed on suchsides of the aprons shallyafter running ldown` such sides, drop or fall into thetrough. 4 Y The block or blocksof ice for cooling the air'within Vthe box are to beplaced onjtheftwo aprnsin manner as shown at I.

Tlie modes" in which the air within the box will be caused to circulate by theice are exhibited, intig. 1,'

"In making my present refrigerator I have avoided the 'employment ofvany air-passages between vthe upper edge 'of the apronD and -the next adjacent side of the case, the apron being fixed close' against such side, thereby Yexpressly avoiding any air-passage and al1 circulation ofthe air.Y between the upper edgeiof the apron andsuch side. In this respect myrpresent refrigerator differs from that for which Letters Patent N011o,112, l(need December 13, 1870, have been granted to me.

In my present refrigerator I get much more room in the case for the packing or hanging or stowage of articles to be cooled or kept in a cool state.'

I am also enabled to manufacture the refrigerator cheaper and to better advantage, relatively to the said patented re'igerator.

By dispensing With the aii-Lpassag'e between .the side of the case and theupper edge of the inclined apron F the air is caused to'have a circulation in two currents, one under and the other over the ice, the

current' going over the ice and against the top of the case: being Arefiected or turned 4back over the icc 'in a manner to be better cooledrthan it would if suffered to iowu'p through an opening at the upper edge of the apron, and thence directly across the ice. The

Yauxiliary current isv caused by the cooling powers of the lower side of the longer' apron. y

The inclined positions of the two aprons, and theV disposition of the trough with respect to them, not

l only enable the vaprons to support the ice, but to conduct into the trough the waste of the ice, as well as the vapor thatmay be condensed-on such aprons.

The refrigerator is found to operate with remarkable efciency, and, as hcreinhefore mentioned, not only to be better calculated for receiving and holding articles to be cooled or preserved, but to. b'e cheaper 'in construction'in respect t'o that. described in my said patent.

It will be observed that, in this refrigerator, I combine the means of producing the reden current over the ice,fvvith, the peculiar arrangement of the two aprons and their trough, whereby not only is the ice disposed to great advantage for cooling from all its surface, but its waste/as well as the condensed' vapors are carried oli" without falling upon any article'or articles when beneath?l the parts for supporting the ice I therefore claim as my. invention- The improved` reirigerator, composed of the case, and the two aprons andA trough arranged within such case, substantially as described and represented, the arrangement involving they longer-apron applied to the next adjacent sideof the case, sot-hat there may. be no `passage between such side and the upper edge' v ot'fthe apron for the air of the'box to circulate through,

all being as set'forth. l
