E. AUGUST KROENKE, OF N E\V YORK, N. Y.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 349,396, dated September 21, 1886.

Application filed July 1, 1886. Serial No. 206,782. (No model.)

To aZZ whom it may concern:

Be it known that I, ERNST AUGUST KROENKE, of the city, county, and State of New York, have invented certain new and use- 5 ful Improvements in Refrigerators, of which the following is a specification.

This invention relates to an improved refrigerator for butter-stores, groceries, beersaloons, 850., in which the front doors, instead of being hinged to the door-casings, are pivoted to the same and arranged to be moved inwardlyin the refrigerator, so as to be entirely out of the way and close the air-channels at the interior of the refrigerator.

The invention consists of a refrigerator the doors of which are applied by guidegrooves to fixed pivots of the door-casing, and moved by horizontally sliding on pivots against the supportingcleat of a deflecting-shelf below the ice-ohamber. A connecting-rod extends from the door to a hinged gate at the rear part of the supporting-frame of the provision-chamher, and opens or closes said gate, so as to close the air-channels. The door itself is pro- 2 5 vided with fulcrunied stop-pieces at the upper part,and pivoted lugs for looking or releasing said stop-pieces, so as to facilitate the removing or replacing of the door, as required.

In the accompanying drawings, Figure 1 3o representsa front elevation of myimproved refrigerator, showing the doors in closed position. Figs. 2 and 3 are vertical transverse sections of the same online a: m, Fig. 1, showing the door respectively in a partly and an entirely Figs. 4, 5, and 6 are details representing, respectively, the door and its pivot-connection with the door-casing and hinged shelf.

Similar letters of reference indicate come .sponding parts.

A in the drawings represents a refrigerator of that kind used by grocers, butchers, saloonkeepers, and others. The refrigerator A is provided with transverse partitions A, and at the 5 upper and lower parts with the usual hinged doors, B, to give access to the ice-chamber and the lower provision-chambers, and at the middle portion with doors B, which are preferably provided with glass panels. instead of being hinged at one side, so as to open outwardly, are pivoted by means of guide-grooves b b at both sides to fixed piv- The doors B,

ots bb of the casing. The pivots b b are applied to straps bf, that are attached to the jambs of the doon-casing and located near the upper part of the said casing, so that the doors B can be swung forward on the pivots in horizontal position, and then be pnshed back by being slid on said pivots into the refrigerator.

until the upper end of the door B arrives on asupport-ing-cleat, d, of a deflecting-shelf, D, which is located below the perforated bottom of the ice-chamber C. When the door B is pushed in, it is supported in a horizontal position by the cleat d and pivots b I), as shown in Figs. 2 and 3. The door B is further connected by a pivot-link, e, with a gate, E, that is hinged to the rear part of a supportingframe, E, which extends from the front of the refrigerator backward to some distance from the rear wall. The gate E is moved downward into horizontal position, so as to rest on a seat, (1, of the rear wall of the refrigerator, when the door B is moved inwardly and supported in horizontal position by the cleat d. When the door B and gate E are moved into horizontal position, the air cooled in the icechamber cannot pass to the outside of the refrigerator,nor the warm air enter through the door-opening to the ice-chamber. The warm air is also prevented from passing to the provision-chamber below the supporting-frame E, whereby the temperature at the interior of the refrigerator is but little affected by the opening of the door, even if the same should be left open for some time.

For closing the door B, it is first moved on its pivots in forward direction until the pivots I) I) arrive at the ends of the guide-grooves b I), as shown in Fig. 2, and then dropped into vertical position, so as to close the dooropening. Simultaneously the hinged gate E is placed into vertical position by the connect ing-link 6, so that thereby the circulation of air from the ice-chamber to the middle and' lower provisionchambers is reestablished.

The door B may be locked in closed position by a suitable locking device. (Not shown in the drawings.) A handle, f, at the lower part of the door serves for conveniently tak ing hold of the door in opening and closing the same.

The door B is provided at its upper part with ful'crumed stop-pieces g, which project into the guide-grooves b, as shown in Fig. 5, and which serve to arrest the forward motion of the door B, and to support the door on its pivots I) I) when it is swung into vertical or horizontal position. The stops 9 are locked in position by pivot-lugs g g, which abut against the inner ends of the stop-pieces, as shown in Fig. 4.. When it is desired to place the door B in position on its pivots, the lugs g are moved sidewise, so as to clear the rear ends ofthe stop-pieces g 9, upon which the latter are moved into a position parallel to each other, as shown in dotted lines in Fig. 4. The ends of the stop-pieces g 9 clear thereby the upper ends of the guide-grooves b b, and permit thereby the removing of the door from the pivots b b, or the replacing of the same in position thereon, as the case may be. By this arrangement the cleaning of the glass panel, as well as the repairing of the door, when required, is facilitated.

By the described hanging of the doors B access is given to the middle chambers of the refrigerator (which are used most frequently) in a very convenient manner, and the escape of cold air from the interior of the refrigerator, and the ingress of warm air from the outside to the interior of the refrigerator, prevented in a reliable manner, so that a considerable saving of ice is produced. The door B is entirely out of the way when in inwardly-pushed position, and can be left in this position for some time Without appreciably lowering the temperature in the refrigerator, which is convenient in removing articles and replacing the same, as the door can be kept open in the meantime.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with an ice-chamber at the upper and aprovision-chamber at the lower part of a refrigerator-chamber, of a deflecting-shelf below the bottom of the ice-chamber, a supporting-frame below the door-opening, a doorhavingsideguide-groovesandswinging on pivots of the door-casing,-a gate hinged to the rear part of the supporting-frame, and a connecting-rod extending from the upper part of the door to the hinged gate, so as to produce simultaneously with the closing or opening of the door the opening or closing of the gate, substantially as set forth.

2. In a refrigerator, the combination of an ice-chamber, a deflecting-shelf below the bottom of the same, said shelf having a supporting front cleat, and a door that is connected byv side guide-grooves to fixed pivots of the door casing, whereby the door can be swung on said pivots and moved inwardly in horizontal position, so as to prevent the escape of cold air from the ice-chamber, substantially as set forth.

3. In a refrigerator, the combination, with the door-casing having fixed pivots, of a door having side guide-grooves, fulcrumed stoppieces extending across the ends of the guide grooves, and pivot-lugs for locking or releasing the stop-pieces, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in pres- 7o ence of two subscribing witnesses.
