REFRIGERATOR.

' Application filed February 2 1, i927. Serial No. 170,520.

' This invention relates to improvements in the construction of refr gerators of the type employed 1n meat markets and stores.

' It is evident that ice boxes and refrigerat' ing cases containing articles of food, such as meat must be kept very clean in order to prevent the food becoming tainted. With the constructionof ice boxes now commonlyeinployed, the bottom of the compartment containing the ice can only be cleaned by first drainage troughcan readily be cleaned without making 1t necessary to remove the ice.

The construction briefly described consist-s in forming the bottom ofthe ice compartment of several removable sections, which can be removed and replaced from below. This makes it possiblefor a person to enter the refrigerating chamber, detach one-of the sections, take it outside and clean it, and then replace it, withoutdisturbing the contents of is also made removable so that it may readily be detached and cleaned. v

In order to more clearly describe the invention and the preferred embodiment thereof,'

. I shall now have reference tothe accompanyin g drawings, in vwhich an ice box constructed in accordance with this invention has been illustrated, and inwhich: I

Fig. 1 is a vertical longitudinal section through one of the improved ice boxes;

Fig. 2 is a transverse section taken on line 2-2, Fig. 1;

Fig. 3 is a section taken on line 33, Fig. Fig. 4 is a section taken on line 44, Fig. Fig. 5 is a section taken on line 5-5, Fig. Fig. 6 is a section taken on line 66, Fig. and v i Fig. 7 is a section taken on line 7 7 Fig. 1.

In the drawings the invention has been,

shown as embodied in the construction of an ice box of usual form, which has a top 1, rear wall 2, floor 3, sides 4 and 5, and whose front sidelis provided with doors 6 and 7 the door 6 opening into the refrigerating chamber and door? closing the entrance tov the ice compartment. The ice in the upper compartment is supported on a series of parallel'slats 8 which are connected by means of transverse pieces9 so as to form several slat sections that can be readily removed and applied in place. I These. slat sections are supported on transverse joists 10, 11, 12 and 13,

which extend from-the front, of thecase to the rear thereof. The upper edges of these joists are protected by means of sheet metal strips 14 and 15'. The strips 14 are of Z shape cross-section and have one side or flange secured to the inner surface of the re- 2 friger ator and are provided with downward- 1y extending flanges 16, which are parallel with and spaced from .the surfaces of [the joists 10 and 13, inthemanner shown most clearly in Figure 3.- Secured to the'upper edges of joists 11'and'12are sheet metal pro- I tectors having a U-shaped cross-section.

The sides 17 oftheseprotectors extend down parallel to the sides of the joists, but are spaced a short distance from the latter. For the purpose of holding the ice in position on mum manner-shown in Figures landv 2.

the slats 8, vertical sides 18 and 19have been provided'along each side of the refrigerator 35 Between each pair of oists, likelO and 11, I

sections 20 have been provided. Thesesec;

formed withboardbottoms 21 whose ends-are 11 and12, and12 and 13, removable bottom secured to strips 22. The space between the strips 22 is filled with a cork insulating material 23. A. sheet metal plate'24 is provided on top of the cork'insulator 23 and is nailed or otherwise secured to the strips 22.' The edges of the sheetmetal plateare'bent at right angles to thebody portion thereof in the I manner indicated by reference numeral 25. These edges extend up" into the space between the joists and the flanges 16 and 17. With this construction any water that flows downwardly over the metal protectors 14 and 15 will be-deposited on the metal plate 24. 'By referring to Figure 2, it will be seen that theremovable bottom plates 20 are so connected to the joists. that they are inclined in a transverse direction. The right hand end of the d supported beneath the lower ends of theseremovable sections, and the metal plate 24 has I its edge 27 bent downwardly in the manner I f29,'which project beyond the ends of the secjoists and extend into the space between them. These bars form supports for the lower ends of the removable bottom sections 20. Secured to the lower surface of the upper end of the removable sections, near each corner, are bars tions and are adapted to be engaged by the horizontal portions 30 of the L-shaped supports whose vertical sides 39 are pivoted at 40. These L-shaped members may be swung into position underneath the bars'29, in the manner shown in Figs. 2 and 3, and will serve to removably support the bottom sections. When the sections are to be removed for cleaning the L-shaped supporting members are swung out of supporting position, after which the sections may be withdrawn from their position on the bars 28, after which they may be taken out, cleaned and replaced. The supporting means which I have described is very well adapted for this purpose, but it may be replaced by any other suitable means. The upper end of the. bottom sections areprovided with a transverse member 41, which fits against the lower edges of the vertical wall members 42 and 43, so as to form a passage 44 through which the warm air may pass upwardl'y. After the air from the refrigerator chamber arrives at the top of the walls 42 and 43, it flows over the ice in the ice compartnient and after it has been cooled, it enters the refrigerator chamber through the passage 45. The water from the melting ice flows from the-bottom sections into the trough 26, which is lined with sheet metal, and after flowing through the trap 46 flows out through a suitabledrain. One end of this trough is supported on an angle iron bracket 47 and the other is supported on a hinged bar 48, one end ofwhicli is pivoted at 49 to the horiz ontal portion of an L-shaped' bracket 50,

while the free end swings into and out of contact with the horizontal portion of the other support (Fig. 7 When the trough is-"to be removed and cleaned,.it is only necessary to swing the bar 48, from its supportvention resides in the sectional construction filling the space between the joists'and having their upper surfaces covered by a metal sheet whose opposite edges are bent upwardly so as to form. upwardly extending flanges and protectors secured to the joists and provided with flanges that extend downwardly beyond the upper edges of and overlap the flanges on the bottom sections. i

2. In an ice box having an upper ice chamher and a lower refrigeration chamberw'separated by a partition on which the ice is supported, a pair of spaced parallel joists extending transversely of the box, a sheet metal protector secured to the upper edge of the joists, said protectors having flanges that arespaced from and? parallel to the sides of the joists, a removable bottom section located between each pair of joists,'each bottom'section filling the space between the joists and having its upper surface covered with sheet metal, the opposite sides of the sheet metal being bent at right angles to .the

.body portion thereof so as to form flanges that extend into the space between the joists and the flanges of the protectors and means for removably securing the'bottom sections in place between the joists.

In testimonywhereof I afiix my signature.
