invention relates to refrigerator cehinets sdopted for domestic use in which thick Weiis oi? insulating meterieiform o chamber N to contain the refrigerating element and food stores, end more particularly to means for enhoncing the utility and capacity thereof,

ifhe principal object of my invention is to provide quick and convenient access to every port of the stoioge pieces.

in second object of my invention is to efiect economy of space required for a, cabinet of a given capacity,

A third and incidentei ohject is to efiect certain economies in refrigeration.

Similar mechanism comprising ne 12 13, and 1 1-, respectively, govern movernent of the links 1 end 3 in equi ongnior movement with respect to t e resenio'st sori oc'e of the drawer.

The door? 16 is hinged to the .cehinet so that it swing shoot an enis iFT'n tuoted epproxinoeteiy es removed from the cchinot opening es the door is thick. Since, it is sound practice to provide equal thermal insulation in the cabinet Weiis end the door the hinging of the door in this wise fixes the position oi the hinge-pin at the extreme corner oi the cabinets This is in distinct con-' trest to the ordinery practice of hingin the docs odjecent the cabinet opg w ich method of hanging the door necessitetes the" swinging thereof through on onguier distence of no degrees, or'thereehouts, to eii feet the foil opening on? the cehinet to show of Withdrawing the drovvers.

In Figure 3 or line A indicates the surfaces of two room-wails forming a. corner in which it is edvnntegeous to piece e refrigerntor in view of the degree of protection such a location in a room provides a ainst warm drafts. Thus located, the full utility of the refrigerator of my invention is in no wise impaired.

A refrigerator of the ordinary type placed in such a position would be diflicult of ac- -cess owing to the impossibility of opening the cabinet to its full width by a movement of the door through a right angle.

While it is acknowledged that a refrigerator of the ordinary type may be protected from warm drafts by placing it in a specially constructed room with a refrigerator niche, it will be obvious that the cabinet of my invention will be of more general utility in its universaladaptablity to any room of the common place design in which the cabinet may be located to advantage in any of the four or more corners.

Aside from these considerations, the times required for opening and closing the door of a given weight, which contemplates the accelerations and retardations of the given mass of the door, through 180 degrees of angular movement on the one hand and through 90 degrees on the other hand, are in distinct contrast.

The drawer supporting and extending device of my invention with its comparatively free and easy motion further eeonomizes the time the door must be held open to accomplish any act of removing or depositin stores. A bowl of liquid to be chilled may be set upon the extended drawer and the same returned to its inner position quickly without danger of spilling such liquid,an advantage accruing out of the easy movement of the drawer.

Specifically, in refrigerator cabinets, exposed surfaces are liable to becoming incrusted with various foreign matter and working surfaces, such as are inherent in the ordinary drawer slides, sooner or later become fouled and prevent the easy motion of a drawer desired. In distinction to this, the device of my invention provides for the constant engagement of all working surfaces and hence the protection thereof against such incrustation.

Further, specifically, any liquids which may congeal about the working parts of the device of my invention, are subjected to a relatively great force to disintegrate the same upon the withdrawal of a drawer owing to the leverages involved as contrasted with an ordinary drawer slide where such congealed liquids obstructing the free movement of the drawer are of greater extent and in simple stress to resist movements of the drawer in easy uniform movement.

It will thus be obvious that the particularv manner of hanging the door in combination with the drawer supporting device contribute in a very definite and desirable degree to the thermal efliciencv of the refrigerator cabinet besides providing for an enhanced facility of removing and de ositing stores.

Having described my invention, what I claim is:

1. A cabinet, a drawer of substantiall the same width as the chamber in said ca inet normally housed therein, and a device extensibly supporting said drawer in said cabinet comprising, two pairs of pivotally joined links extremities of which pairs are pivotally attached to inner corners of said cabinet and said drawer respectivel and means for constraining the lin s attac ed to said drawer and the links attached to said inner cabinet corners to equi-angular motion respectively.

2. A cabinet, a drawer of substantiall the same width as the chamber in said ca inet normally housed therein, and a device extensibly supporting said drawer in said cabinet comprising, two pairs of pivotally joined links extremities of which pairs are pivotally attached to inner corners of said cabinet and said drawer respectively and two levers pivotally attached to said drawer and the rear inner wall of said cabinet respectivel equal arms of each thereof being pivotal y connected by suitable rods to each of said links respectively to constrain the links attached to said drawer and the links attached to said inner cabinet corners to equi-angular motion respectively.

3. A cabinet comprising, an open chambar, a door of the same thickness as the walls of said chamber forming a closure therefor, hinges attaching said door to a wall of said chamber in which the axes thereof are disposed in a plane which bisects the angle included between the inner adjacent sides of said chamber wall and said door when the latter is in the closed position, a drawer of substantially the same width as the chamber in said cabinet normally housed therein, and a device extensibly supporting said drawer in said cabinet comprising, two airs of pivotally joined links extremlties 0 which airs are pivotally attached to inner corners 0 said cabinet and said drawer res ctivel and means for constraining the link: attac ed to said drawer and the links attached to the said inner cabinet corners to equi-angular motion respectively.

4. A cabinet comprising, an open chamber, a door of the same thickness as the walls of the said chamber formin a closure therefor, hinges attaching said oor to a wall of said chamber in which the axes thereof are disposed in a plane which bisects the angle included between the inner ad'acent sides of said chamber wall and said oor when the latter is in the closed position, a drawer of substantially the same width as the chamber in said cabinet normally housed therein, and a device extensibly supporting said drawer in said cabinet comprising, two pairs of pivotally joined links extremities-of which pairs are pivotalIy attached to inner corners of said cabinet and said drawer respectively and two. levers pivotally attached to said drawer and t0 the rear inner wall of said chamber respectively equal arms of each thereof being pivotall connected by-suitable rods to each of sai links respectively to constrainthe links attached to said drawer and the links attached to said inner chamber corners to equi-an ular motion respectively. 1
