'lClaiml.

Refrigerator cabinets as commonly constructed have doors of a thick insulated type which close into a recess within the cabinet opening, such opening being formed with edges within which the door closes. Such a structure necessitates positioning the front edges of the shelves baclr from the front, using a considerable portion of the interior for the door, and also makes necessary the displacement of a considerable volume of air, or the compression of air within the cabinet, when said door is closed.

The object of my said invention is to provide a refrigerator cabinet, the entire interior of which up to a plane flush with the faces 0! the edges surrounding the door opening will be available for use and in which the iront edge of the shelves may be flush with the front face of the cabinet.

In carrying out my invention I provide a cabinet constructed as indicated with a door or doors adapted to close against the face of the edges of the cabinet which surround the door opening: and without any portion of the door projecting within the cabinet. By such a construction I provide a cabinet which when open presents an interior completely accessible and available for use to a point flush with its front face; and one wherein the opening and closing of the door or doors will cause a minimum of disturbance of the air within by reasons of compressing or displacing the same when the door is closed, or by permitting its expansion when the door is opened. and with a consequent undue inrush of warm air from without and loss of cold air from within. I also provide a cabinet with a smooth front unbroken by seams, joints or crevices, which presents a most attractive appearance and provides a structure easy to keep in a clean and sanitary condition, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts.

In carrying out my invention a cabinet I! is provided having a food compartment It in which are mounted suitable shelves or supports ll.

These shelves extend forward flush with the'front walls of the cabinet. The compartment of course may be cooled in any suitable way, either by mechanical refrigerating mechanism or by ice.

A door I2 is hinged to the side wall of the cabinet. In one form of the invention the width of the door is preferably the full width of the cabinet proper so that when the door is closed the sides of the door are flush with the outer walls and top of the cabinet. A fastening I3 is provided for locking the door which fastening will later be described more in detail.

In order to eflect a perfect seal between the door and the walls of the cabinet against which it engages elastic packing strips it may be secin'ed either to the door or to the adjacent faces of the edges of the wall of the cabinet. A refriserator cabinet such as the one illustrated usually has a compartment i5 beneath the food compartment which compartment may contain the mechanical refrigerating mechanism when such a unit is employed. This compartment is closed by a removable panel It. This panel is secured in position by pins I! which are fixed in the lower portion of the cabinet proper and extend into sockets 2| in the lower portion of the panel. Several of these pins may be provided. Instead of having the pins secured in the cabinet and extending into the panel they may be fixed in the panel and seat in sockets in the lower portion of the cabinet. The upper rear portion of the panel is provided with slots at 2| which engage over screw heads 22 which are fixed in a portion of the cabinet. Thepanels it are positioned in the cabinet by sliding the slotted portion over the head of the screws and then allowing the panel to seat so that the lower portion is secured against forward movement by the pins I9. The panel 0! course is put in position while the cabinet door I! is open.

The door I! may be lined with a plate l'l. This may be a flat plate which is secured to the inside of the door I! proper. Such a plate is easily and inexpensively constructed. If preferred the door lining I! may be indented so as to provide a slightly larger compartment. whether flat or whether indented, however, closing of the door will not cause a compression of the air within the compartment nor force cold air from the com- ,partmenttotheoutsidesincethedoorwillclose flush against the outer edges of the walls of the cabinet.

Means for locking the door to the food compartment areshownindetailinl lgures2 and 4. Attachedtothesideofthedoorisastriker bracket 23 adapted to engage a notch in a cylinder 24. The cylinder is rotatably mounted on a shaft 30 mounted in a bracket 25 which is secured to the wall of the cabinet in any suitable way. A rod 25 is pivotally attached at 29 to the cylinder 24 and is slidable in a sleeve 21 which is pivotally mounted on the bracket 25. A compression spring 28 is mounted about the rod 28 between the sleeve 21 and the cylinder 24 and when the door is closed is under tension to urge the cylinder 24 in a counter-clockwise direction. When the door has been opened the cylinder 24 will be rotated clockwise to swing the pivot point 29 below the shaft 30 on which the cylinder 24 is mounted so that the spring will tend to urge the cylinder in a clockwise direction. The locking cylinder 24 may be rotated by means of a pedal 3| which is pivoted to the base of the cabinet and connected by means of a link 32 with a tie fork 33 which is pivotally secured to the cylinder 24 so that downward movement of the pedal 3| will rock the cylinder in a clockwise direction to open the door. A spring 34 tends to restore the pedal and the operating link 32 to its upper position when pressure has been released from the pedal.

In the modified form shown in Figure 6, two doors 35 and 3B are provided, these doors being hinged to each side of the cabinet. The locking mechanism for the doors and other features of the cabinet are the same as those described above.

From the foregoing description it will be apparent that I have provided a refrigerator cabinet having smooth exterior walls and a door which provides a neat seal between contacting portions of the door and cabinet; and one wherein the closing and opening of the door will cause a minimum of disturbance of the air within the cabinet since no portion of the door extends into the cabinet proper to cause compression of the air within the cabinet or forcing of the air which is in the cabinet out past the edges of the door.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the spirit of the invention and therefore I do not limit myself to what is shown in the drawings and described in the specification, but only as indicated by the appended claims.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
