,- citizen of the United States, residingl et 3553 Visto Street, St. Louis, in 'the Stute l5 of Missouri, have invented certain new end useful Improvements in Refrigerators, of which the following is a specification.

My invention has relation to improve-- ments in refrigerators and Vconsists in the l novel features of construction more fully set forth in the specification and pointed ont in the claims,

The object of hthe present invention is to provide e refrigerator oi the display cese type with :in ice chamber preferably :it each end, end n storage elia-lieber having ineens 'for facilitating the nir circulation throughout its extent, which is very important tor preserving perishable toodstnlis. i

A further object of this invention is to lprovide an ice container that may be easily moved out of its chamber 'for e. fresh snpply of ice and es easily moved beck in place again. Further and .other advantages will be better apparent from s detailed description of the invention in connection with the accompanying drawings in whichm Figure l is e combination rear elevation -`ind vertical longitudinal section of the refrigerator; Fig. Q, is on enlarged middle vertical longitudinal section through one-half the refrigerator and its ice container; Fig. 3 is an enlarged horizontal longitudinal section on the line 3-3 of Fig. l; Fig. is a. Vertical cross-section on. the lin-e 4 4 of Fig. 3; Fig. 5 is e sectional detail of the return flue inlet taken 'on the line 5-5 oit Fig. 2; Fig. 6 is o to plain detail of one oit" the ice container rai s and extension thereof; Fig. 7 is e detail view showing one of the comer-ongles on which the extension rail is pivoted; and Fig. 8 .is :i cross-sectional detail teken on the line 8-8 of Fig. 7.

Referring to the drawings, A represents the refrigerator case having an ice ch'zmber C et each end and e storage or provision chamber B in the middle, there being Adoors D, lli in the rear Well of the ice chzunbcrs anddoosD, D' in the rear wall oi the provision chamber. The provision chamber is also equipped with the usual `gloss panels at the iront.

There are two 'vertical ingle members l, Leecuied to the rear woll aJ ozt 'the ice chainber, said angle members extending slightly inside the door opening O, p

A rail 2 1s secured et one end to `each angle member l, o short distance -from the top' thereof, the other end o1c the rail being secured to :i strip 3 fastened 'on the front well o of the ice ehe-roher. There is also on extension rail 4 pivotelly connected to each nieniber l in line With the rail 2 so that when the I'oil t is raised to a' horizontal position it will 'form a continuation of rail 2 (dotted Fig. d). rails 4, 4l in their horizontal position o brace bar 5 is pivotslly connected on the outside of oooh near the free end thereof, said brace ber 5 being spaced :troni the rail 4i. et the pivot 6 by n Washer 7 sud'ieientlykso that the ber 5 may operate through a. slot 8 in the angle member l. The` free ends of rails 4, 4 ere connectedl by a rod 9 so they Will move together. `W hen the rails 4f, l are lowered to vertical position the brace bars 5 extend back into the icc chamberl'C, and are supported by pins 10, l0 in e horizontal position. Noivf, on raising rails d, e to n horizontiil position they `will pull the brace hars 5, 5 out oit' the ice chamber through the slots 8, 8 in, members l, l, and when the ln order to hold the rails are ino horizontal position their inner ends will abut the adjacent ends of rails 1, l thus arresting turther'movenient, and at the seme tune-the notches n, n, in the lower ends ot bers 5, 5 will drop onto the bottom edge of slots 8, 8. The. extension rails are now lirnily held in extendedfposition lAn ice container 1l is positioned Within the ice chamber C seid container having aiA pair of spaced rollers 12,12 on each side whereby it is rollingly supported on rails f2, 2, Within the container 1l, and extending from side to side thereof et the bottoni .are two inverted ii-shaped bottom members inlet opening l5 centered near the top of.

the container and an outlet opening 16 centered near the bottom of the container 4sei-d outlet being considerably lurger than the inlet, both openings being in the side of the container toward the provision chamber B. The line -is gently Acurved from the inlet into the container. somewhat eral shape is that of a Cornucopia, although a crosasection taken on any lane is rectangular. interior of the refrigerator in rorit of the outlet opening 16 and forms a division line between provision chamber B and ice chamber C, however there is a space 18 between'vthe to of the baille andan intermediate shel 19, 'and a space-2() between the bottom of the baille and the brine tanlr,fsaid spaces forming passages for the cold air as it issuesfrom the fine 14, and the baliie 1.7;serving to direct the cold air toward,A the sheli" 19 and a second shelf 2l near theA bottoni of the provision chamber B.

At the middle of the top of the provision chamber B is an air collector 22, said collecto'rextending" across the chamber and having an elongated inlet opening 23 in echside wall thereof. The ends of collector 22 connectuwith .air conduits 24e, 24

liti

extending along the sides of the provision chamber and leading to a box 25 supported by the inner rail 2 said box also receiving the inlet of iue 14. y The side Wall 25 of box toward the ice chamber door D Yis open so that the inlet end of line 14 may pass freely out of the box when the ice container' is rolled from its chamber.

Resting on the bottom oi the provision chamber is an enclosed brine circulating tank' 26 which receives the brine overflowing from the lip 27 ci the tank 13, said tank having a raised bottom 28 and a top Wall 29 through both of 'which pass a series of lines L30 through which the air maycirculate as it moves through the chamber B. The surfaces of the lines are kept cold by the brine within tank 26 hence these fines serve' as auxiliary cooling means for the air. The end of brine tank 26 farthest from the ice cham vberC is provided with an overflow pipe 31 through which fthe brine discharges into basin). which is connected with the sewer not shown).

In operation the ice container 11 is lled with; cracked ice and salt, which operation Ais easily accomplished by opening door D,

raising 4extension rails ,4; as Aheretofore describedfand rolling the'icecontainer out of chamber C. The container 1l. is then pushed Qback into place and door D closed. As the A baile 17'exten`s across the,

shell through space 20. This compie ment of cold air will be advanced through the dprovision chamber by that coming behin it, and4 as it passes along its temperature will naturally rise, the air then rising in the provision chamber. As this warmer air ap roaches theair collector 22 it will be sncke intoit through openin 23, since there is a circulation created in t e conduits 24 by. the, cooling flue 14, and this warmer between bottom members 11, 11. In order that this ice may not fall on the floor I provide a tray 33hinged to the bottom of members-1, l -said tray beingv lowered to the dotted position (Fig. 4C) when the container l1 `is being charged. When the tray is raised before closing door D these pieces will be dumped into brine tank 13.

Having described my invention, I claim: 1. In a refrigerator comprisin a case having a provision ychamber an an ice chamber, an ice container .in said ice chamber, an air cooling flue Within the ice container, said flue having an inlet near the top of the container and openingl toward the provision chamber, and an outlet near the =bottom of lthe container, extending across substantially twothirds the Width of the container, and openn ing toward the provision chamber, a shelf within the provision chamber near the bottom thereof, a shelf intermediate the bottorn shelf and the top of said chamber, and

a battle' late spaced from the. ice container and in ront of the'air liuc outlet for deiecting the cold air issuing from said outlet toward said shelves.
