Specification of Letters Patent.

Patent-ed May 5, 1914.

Application filed July 2, 19-10. Serial No. 570,133.

To all whom it may concern:

Be it known that I, FRANK J. DUX, a citizen of the United States, residing at Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to an improved refrigerator and I declare the following to be a full, clear, concise and eXact description thereof sufficient to enable anyone skilled in the art to make and use the same reference being had to the accompanying drawings in which like reference characters refer to like parts throughout.-

The-object of the invention is to provide a refrigerator adapted more particularly to be set up permanently into the framework of a house under construction although it may be built independently thereof.

I propose to construct the refrigerator in sections that it may be the more easlly packed for shipping to its destination. The sections are so arranged, however, that they may be easily and readily assembled.

The frame work of the refrigerator is constructed of angle iron to which is riveted or suitably secured sheet metal and the whole is then preferably covered with concrete because of its non heat conductive property and hence its usefulness to refrigerate. In order to avoid the cracking of the concrete because of the slamming of doors that are usually hinged at the side and open outward I employ a sliding door to give access to the food compartment of the refrigerator.

Further objects will appear by referring to the drawings in which Figure 1 is a perspective view of my improved refrigerator showing one of the sides broken away; Fig. 2 is a front elevation showing the door broken away that the interior parts might be seen; 3 1s a plan view of the refrigerator with the top removed; Fig. 4 is a fragmentary view of the door to the ice chamber and partsin connection therewith, looking from the interior outward; Fig. 5 is a fragmentary view of the door to the food chamber showing the mechanism for actuating same; Fig. 6 is a section on the line 66 of Fig. 2 and also a plan of the cam or eccentric; Fig. 7 is a fragment of angle iron employed in making the frame of the refrigerator; Fig. 8 is a side elevation of the refrigerator showing the frame work without the addition of the sheet metal and concrete; Fig. 9 is a modified form of the rear of the refrigerator, showing a door giving access to the food compartment, similar to the door on the front of the device; Fig. 10 is a skeleton view of the frame work before the sheet metal, cross bars and concrete have been added; Fig. 11 is a perspective view of the door of the food co1npartment, the front casing being removed; Fig. 12 is a plan view of the device before the front and rear door casing have been added, showing the sheet metal covering the top and bent to give place for the stay rods that hold the sections together; Fig. 13 is a perspective view of the ice pan, and Figs. 14 and 15 are details of braces employed on the device.

Referring more particularly to the drawings the sides 1 and 2 and back 3 are constructed separately and are held together in assembled position by stay rods 4, four in number, headed as at a and running transverse of the refrigerator. screw threaded at one end to adapt them to be screw mounted into angle irons 7 of side 2 and also for the screw mounting of nuts 6. Sides 1 and 2 are of similar construction, embodying an angle iron such as 7 running up the front, across the top and down the rear and strengthened by a plurality of cross bars 8 made of angle iron and disposed with apex 9 thereof against one surface of angle iron 7 and secured thereto by rivets 10 or in any suitable manner. Such disposition of cross bars 8 tends to retain the concrete in position on the frame work covered with sheet metal A more effectively. At 11 I employ a piece of angle iron disposed with one side flush against the inner surface of iron 7 and having its upper surface or shoulder 12 projecting inwardly adapted to be engaged by cross bars 13 recessed as at 14 in a manner adapted to permit surface 15 of bars 13 to lie or rest normally upon surface 12 of bar 11 so that when bar 13 is assembled with both ends similarly engaging opposite bars such as 11 and 11 it will hold sides 1 and 2 outwardly in a rigid manner. Bars 11 and 11 are recessed near their front portions as at c in order to provide clearance for ice chamber door 20. The back is formed Said rods 4 are a of angle irons with one flange horizontal for supporting the covering, of concrete or the like. The irons are formed to be attached to the side pieces and together and with the adjacent edges of the sides form the back. The same is true as to the front, except in so far as a less number of such irons may be needed because of the larger openings which are to be provided for. Straight across the front in a plane with bars 11 and 11 a bar g adapted to form the lower casing for ice chamber door 20. Upon bars 13 is disposed pan 16 mounted upon blocks 18 in a manner adapted to cause the water that collects thereon to gravitate toward outlet opening 19 disposed preferably at one corner of the refrigerator in order to be in a convenient position provided it is found desirable to gain access to the refrigerator from both front and rear.

Access is gained to the ice chamber by means of door 20 pivotally swung upon a bar 21 having bearings in angle iron 7 of side 1 and 7 of side 2 and said bar is headed as at 22 and secured in position at its remote end by nut 23. Upon bar 21 is disposed a plurality of bars or supports 24: for ice and running thence backward on an incline to and secured upon bar 25 rigidly mounted to angle irons 7 and 7 of sides 1 and 2 respectively. Door 20 is provided with a pivotally mounted handle H countersunk in the casing of the door and adapted to be a means by which said door may be pulled outward and journaled upon rod or bar 21 until it comes to rest or abuts against the under sides of bars 24 whereupon said door will lie in the same plane with said bars 2 f so that the ice may be placed upon said door 20 and slid into the ice chamber upon bars 24 in a most advantageous manner without any racking or breaking of the refrigerator. Furthermore door 20 is constructed of a frame 26 supported by braces 27 and may have its sides lined with any suitable packing material to cause said door 20 to fit snugly against its adjacent frame or casing, as indicated at h in Fig. 1. Below the ice chamber is the food chamber divided into any suitable number of compartments and having a frame covered with sheet metal and concrete for its bottom. The front of the chamber is closed by a slidingly mounted door 28 adapted to be slid in a manner that will expose one half of the food chamber at a time. The mechanism for thus actuating the door embodies casings 3030 rigidly secured to door 28 and adapted to slide upon correspondingly shaped inner casings 3l-31 rigidly secured to the front portions of angle irons 7 and 7 of sides 1 and 2 respectively and adapted to form a box covering for weights 32-32 connected one on either side to door 28 by ropes 33 riding over pulleys 31-34. journaled on bearings secured to the upper portions of casings 31-31. The total weight of members is a little greater than that of door 28 in order that door 28 will tend normally to rise, said door 28 may be held, however, in any desired position within the limits of its movement by turning the handle 35 rotatably mounted in cross bars 36-36 of door 28. Said cross bars are covered on one side with metallic plates 37 adapted to form a bearing for shaft 38 of handle 35. To the end of shaft 38 is rigidly secured a cam or eccentric disk 39 having a bearing or being supported between bars 10 and 4:1 mounted in the casing of the food chamber as seen in Fig. 2. Bar 4:1 is slightly thicker than bar 40 in order to adapt cam 39 when turned in the direction indicated by the arrow to engage in a wedging manner bar 41 because of the constant distance between ring 12 rigidly held to shaft 38 and cam 39. The turning of handle 35 and the consequent wedging of cam 39 upon bar 41 further serves the purpose of drawing door 28 tightly against its adjacent casing of the refrigerator and the consequent closing of the door 28 in an air tight manner.

The rear or back part of the refrigerator may be also provided with a door such as 13 built similar to door 28 and sliding-1y mounted in the same manner as more fully shown in Fig. 9. Access to both front and rear portions of the refrigerator may be found desirable in the event that the refrigerator is placed in the wall of two adjoining rooms of the house. In this last described construction, however, the ice chamber will not be accessible from the rear but the portion corresponding to the door in front will be provided with a frame 44 shown in Fig. 9 and upon said frame may be mounted a piece of sheet metal A. and concrete as in the case of sides 1 and 2 and back 3 of the former construction. Slots 50 are provided in the rear wall of the ice-pan 16 for rods 24.

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

1. In a refrigerator formed with an ice chamber. a door to said chamber, the same being pivotally hung on a transversely disposed bar engaging the door between its upper and its lower edges, a plurality of bars extending from the said first mentioned bar across said chamber, the said latter bars engaging one edge of the said door when the same is opened whereby the said door extends outwardly in the form of a shelf and substantially in the same plane with the said latter mentioned bars where by the said door and the said bars form Eieans for the passing of ice into the cham- 2. In a refrigerator, a door adapted to he slid vertically and having casings secured on its vertical edges and overlying the same, casings secured to the refrigerator adapted for the engagement of the former casings therewith in the movement of the door, the latter casings being of a form to provide a vertically extended chamber between the casings, and a counterweight applied to the door for the movement of the same, the said weight traveling in the said vertical chambers.

3. In a refrigerator, the combination with frames, of two bars vertically disposed in the doorway of the refrigerator and of different thicknesses from front to back, a vertically sliding door, a lock in the door comprising a shaft passed through the door between the said bars and having at its inner end a cam faced disk whereby the turning of the shaft will press the cam-face of the disk against the thicker of thebars and thereby retain the door in chosen position.

In testimony whereof I have hereunto aflixed my signature in the presence of two witnesses.
