Refrigerators; and I do -herebydeclare the following to be a full, clear, and exact descripton of the invention, such as will enable others skilled in the art to which it appertains to make and usethe. same.

This invention relates to refrigerators. It is a primary object and purpose of my invention to make a refrigerator lining of what is known as L-shape, this lining being designed to be covered with porcelain on its inner sides and form the lining of the provision receiving compartments of the refrigerator, and to construct said lining in a particularly novel and serviceable manner so that the corner where the horizontal and vertical sides of the lining `1`oin is fully supported and-hold securely against any tendency to sag under its own weight. A further object of the invention is to construct a refrigerator in which use is made of said lining, and to provide the same with many novel features of Construction, particularly in a novel manner of finishing the refrigerator at the door openings and in a novel construction for rendering the doors 'air from which 'the back and ends of the lining' are'made.

Fig. 2 is a perspectivefview showing said blank bent into form to make said back and ends of the lining.

Fig. 3 is an elevation of a blank used with the blank shown in Fig. 1 to complete the L portion of the lining, except for the bottom and top of the Vertical part of said lining.

Fig. 4 shows the blank of Fig. Blbent to form, looking at the same from the rear.

Fig. 5 is a plan view of the construction shown in Fig. 4. i

Fig. 6 is a front elevation of thecomplete L-shaped lining.

F ig. 7 isa fragmentary Vertical section showing the means used to connect the lining with the ice box lining at the upper flue opening which must be made between the ice box and provision chamber of, the refrigerator. i

Fig. 8 is a plan of a member used to complete the post between the bottom of the lining and the corner of the L.

Fig. 9 is a front elevation thereof.

Fig. 10 is a horizontal section' taken through the lower part of a refrigerator equipped with the lining, the method of finishing the refrigerator at the door openings being shown.

Fig. 11 is a Vertical section through the bottom of the lining, and

F ig. 12 is a horizontall section illustrating the construction used at the flue opening made in the partition between the ice chamber and the provision compartment below it.

Like reference characters refer to like parts in the different figures of the drawings.

To construct the lining, there is first provided a blank of sheet metal such as shown in Fig. 1, including a relatively wide Vertical portion or section lfroxn which, at its lower end and at one side a horizontal section 2 projects. Integral with the section 1 is an end portion 3, which it is w. designed shall be bent forward from the section 1 on the vertical line 4. Similarly a shorter end section 5 is bent forward from the part 2, being bent on the line 6. Each of the

ends

3 and 5 are bent inwardly toward each other adjacent their front edges, as indicated at 7, and thence turned outwardly to make vertical flanges 8 positioned at the front edges of said

sides

3 and 5.

In connection with the form of sheet metal bent into the shape shown in Fig. 2 and previously described, a second sheet metal form is used, made' from a blank of Sheet metal a's shown in Fig. 3. The plate 9 of sheet metal is slitted from its lower edge and a short distance back of the front edge thereof upwardly for a distance asindicated at 10,'leaving two separated parts 11 and 12. The part 12 is turned upwardly to horizontal position, being bent along the line 13, and the form thus made is placed so'that the horizontal portion 12 forms a top for' the outwardly extending part of the lining and the Vertical portion 9 parallels the side 3 and lies directly in front of the free edge 'the portion 12 to the upper edge of the back section 2 and of the free end edge of 'said part 12 to the upper edge of the end 5, thereby securing the two sheet metal forms permanently together.

The usual flue opening 14 is cut through the top'12 while adjacent the upper edge of the side 9, a flue opening 15 is cut, being practically'adepression at the upper edgeof said side 9 as shown. The metal around said depression is turned outwardly making a flange 16 bounding the lower side of the depression. Similarly, the metal around the opening 14 is turned upwardly making a continuous flange' 17 entirely around the opening.

At the front edge of, the side 9, a width of metal equal to the width of the narrow section 11, and in alinement therewith,is bent inwardly toward the opposite inwardly pressed portion 7 of the end 3, as indicated at 18 and then bent forward as shown at 19. The section 11 is similarly formed, the formation shownv at 18\ and 19 extending from the lower end of the section 11 to the upper edge of the side 90 Below the horizontal top 12, a metal reinforce or post is secured to section 11 bent into the form described, said post being made from a strlp of metal and formed with a back 21 from which `a flange 22 extends forward at one edge.

The back 21 is placed against the inwardly .bent portion 18 and welded thereto, making a stron su ortin post.

The iippieprp end gof the lining made by back 1, and sides 3 and 9 is completed by a plate 20 of sheet metal welded into place, it bein provided with an upturned fiange 2021 at 1ts front.. The bottom is made by al plate 23 of metal welded to the lower edges of the

back portions

1 and 2 and the lower edges of the

ends

3 and 5. Said bottom is formed near its front with an upraised section extending the full width of the bottom and at its front edge a flange 25 is turned down therefrom.

The complete lining is shown in front elevation inv Fig. 6. The ice chamber is located above the

top

1,2, its inner side 26 paralleling'the sideL 9 but spaced therefrom as shown in Fig. 7. The'flange 16 extends toward side 2.6 of the ice chamber and in practice is connected thereto by a coupling 27 formed with'a fiange 28 to bear against the inner side 26 of the ice chamber lining and witha* return U-shaped bend 29 which grasps 'the 'flange 16 as shown. Any suitable 'wood insulating member 30may be disposed between side 9 and side 26'as isusual in` refrigerator construction.

The ice chamber also has a lining, the bot-tom 31 of which has an opening therein coming directly over the opening 14 in the .sulating member 36 is likewise used between top 12 of the lL-shaped lining and the bottom 31 of the ice chamber lining.

The lining constructed as describe is -built into a refrigerator in much the usual manner, there being a frame having Vertical side posts 37 anda central post 38 at the' front against which the fianges 8 come, be-

.ingsecured thereto by screws or other suitablefastenifg means. The central post covers the .metal reinforce shown atv21 and 22 and also-the. section 11 bent into the back 18 and forwardly extending flange 19. This frame is in turn coVered by the outside front casing of the refrigerator included in which are the Vertical side members 39 and the central member 40 as shown. Thefianges 20a,

12a and 25 serve to connect the lining at top and bottom to the refrigerator front frame first described and thus firmly secure the lining in place, screws or other suitable fastening means passing through the fianges into' horizontal cross members of the frame.

Vertical finishing strips 41 are located one against the part 19 and one against part 22' back `of the post. 38, being secured in place in any suitable manner. Similar but slightly modified strips 42 are secured back of the posts 37 lying against the inwardly inclined portions 7 of the sides of the lining. 'This makes a particularly sanitary construction,

particularly in connection with the inner pprcelain covered sidesof the refrigerator lining. The doors 43 closing the openings at the front of the refrigerator are of usual construction but need not be made to closely fit the doorV o enings as the Vertical edges of

posts

37 and 38, as well as the corresponding cross members at the door ,openings lare equipped `with rubber channel shaped strips projecting into the door openings in, position to be engaged by the door as shown in F ig. 10, whereby a tight seal against the escape of cold air is made, the rubber yielding readily when the door is closed but alsupported against sagging by'the Vertical part 11 depending therefrom and connected to the bottom 'of the ,lining The raise at 24 in the bottom of the lining leaves the majorportion of the lining in a plane be- 'metal member having a Vertical slit therein' 'f and durable.
