ROBERT LAUPIIEIHER, OF BALTIMORE, MARYLAND.

REFRIGERATOR OR CQLD-STORAGE RECEPTAOLE.

SPECIFICATION forming part of Letters Patent No. 629,572, dated July 25, 1899.

Application filed February 3,1899. Serial No. 704,362. (No model.)

To ctZZ whmn it may concern.-

Be it known that 1, ROBERT LAUPHEIMER, a citizen of the United States of America, and a resident of Baltimore city, in the State of Maryland, have invented certain new and useful Improvements in Refrigerators or Cold- Storage Receptacles, of which the following is a specification.

The object of my invention is to provide a refrigerator or cold-storage receptacle which in addition to its mechanical features for convenience and economy has the further advantage ofbeing more easily kept clean than similar articles now on the market.

My invention consists in a refrigerator and in details of construction thereof, as herein set forth and claimed.

In the drawings, Figure 1 is a front view. Fig. 2 is a side view. Fig. 3 is a vertical section through d. Fig. 4 is a vertical transverse section through A B. Fig. 5 is a vertical transverse section through E F. Fig. 6 is a plan view of the ice-box. Fig. 7 is avertical section of the ice-box. Fig. 8 is a plan View of the drip or water pan. Fig. 9 is a transverse section of the drip or water pan. Fig. 10 is a plan view of the removable foodcage or storage-receptacle. tical section of same. Fig. 12 is a plan view of a front removable section or sill. Fig. 13 is a removable segment of the same.

Referring to the drawings, 1 is the refrigerator casing or box, having a door 2 in the front, said door opening into a cold-storage compartment 3, as shown in Figs. 3, 4, and 5.

The refrigerator is provided with an airspace 4 between the outer casing 1 and the inner lining 5. The top is covered by two hinged doors, which in addition to the hinged connections 8 and 9 at the back are provided with a second set of hinged joints 10 and 11, the joints being so placed with respect to each other that one part of the top door 6 overlaps the joint 11 in the lower door 7, thus providing a much more perfect air-tight joint than if the hinged joints were directly in line with each other.

Another important feature is that by providing the joint 11 in the lower door 7 it is possible to replenish or remove a portion of the supply of ice in the refrigerator by simply raising the small section 12 of the lower Fig. 11 is a ver-- door, which, as it is comparatively small, does not admit as much warm air into the refrigerator as would be admitted if it were necessary to raise the whole of the top covering, as would be the case if the door 7 were not hinged at 11 in addition to the hinged connection at the rear.

The cold-storage compartment 3 contains a removable box or lining 13, (shown in detail in Figs. 10 and 11,) which is made of sheetiron or any suitable material and constructed with shelves 14: and 15 for holding food. 16 and 17 are handles by means of which the box 13 may be withdrawn from the refrigerator. Supported at 13 by a flange or any other suitable means is a second box 18, adapted for the storage of ice. (Shown in detail in Figs. 6 and 7.) The bottom of this ice-box 18 is so arranged that any moisture due to condensation in the compartment 3, which collects at the top of said compartment on the bottom of the ice-box 18, will run along this surface in a certain direction and drop into a receiving-trough 19, supported on the side of the box 13. This result is accomplished by constructing the bottom of the ice-box 18 with a slight slant in one direction toward the trough 19.

Supported on the bottom of the ice-box 18,

is an ice-water pan 20, (shown in detail in Figs. 8 and 9,) said pan being provided with a pair of perforated hinged covers 21 and 22. The projecting edges 22 are provided with breaks 22" at the corners for the purpose of permitting a free circulation of cold air around and under the pan 20. As the ice melts, the water drops through the perforation in the covers into the pan and may be drawn off through the pipe 23 and cook 24E,which extend to the exterior through the slot 25 in the icebox 18 and through the casing of the refrigerator. In order that the ice-water pan 20 may be removed without unscrewing or detaching the pipe 23 from said pan 20, I provide a removable sliding section or sill 26 in the refrigerator-casing above the pipe,which may be raised up out of the way of said pipe, thereby making it possible to lift the ice-pan 20 out at the top of the refrigerator. The section 26 is dovetailed, as shown in Figs. 1, 12, and 13, directly into one side of the refrigerator-casing, the other side being dovetailed into a second sliding section 27 ,whichin turn is dovetailed into both sides of the refrigerator-casing, as shown in Fig. 1. Upon removing the section 27 and opening the door 2 the box 13 may be drawn out by means of the handles 16 and 17. From the above description it is evident that the whole front wall of the refrigerator may be removed from side to side, this being a very advantageous feature, as it renders the interior very accessible for cleaning purposes.

- the pan 20, or in cases where the pan 20 has been removed from the refrigerator, I provide openings 28 in the bottom of the ice-box 18, said openings being directly over the trough 19. From the trough a pipe 29 runsto the exterior of the refrigerator, passing through a slotted opening 30 in the bottom, as shown.

In very large refrigerators it may be neces sary. to support the box 13 on rollers, so that it may be easily moved in and out of the refrigerator.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-- 1. A refrigerator, consisting of an exterior casin g, in combination with a removable foodreceptacle, or cold-storage box, and a removable ice-box, the Whole front of the exterior casing in front of the food-receptacle consisting of a hinged door, permitting the independent removal of the food-receptacle, and the whole front of the casing in front of the icebox, consisting of a removable sliding section, provided with a subsidiary removable sliding section, permitting of the independent removal of the ice-water pan, as herein set forth.

2. A refrigerator provided with doublehinged covers at its top, said covers being each formed in two parts hinged together, so

as to form flaps, the joints of the flaps being in different vertical planes, as and for the purpose set forth.

3. I11 a refrigerator, an ice-box, in combination with a receptacle for containing ice- Water, said receptacle resting on the bottom of the ice-box, and adapted to support ice placed in the ice-box, and having an apertured top for the passage of drip from the ice, consisting of perforated hinged doors, and flanged at its top for the support of the ice, said flange being apertured for the passage of drip, as and for the purpose set forth.

4. A refrigerator having the front upper side of the exterior casing in front of the icebox, formed of a sliding removable section, permitting of the removal of the ice-box, and a subsidiary sliding removable section in the main section, permitting of the independent removal of the ice-water pan, as and for the purpose set forth.

5. A refrigerator having the front upper side of its exterior casing opposite the icebox, formed of a removable sliding section, and a subsidiary removable sliding section for the independent removal of the ice-Water pan, and the lower front side of the exterior casing, consisting of a hinged door opposite the food-receptacle, in combination with a removable ice-box with inclined bottom, having apertures at its lower end, a removable food-receptacle, a drip-trough located beneath the apertures in the ice-box and having an outletpi pe extending through the food-receptacle, and an ice-water receptacle located in the ice-box and having an apertured flanged top adapted to support ice, with an outlet pipe and cook for the ice-water receptacle, the several parts enumerated being removable, as set forth.

Signed by me, at Baltimore, Maryland, this 25th day of January, 1899.
