LOUIS PEROTTI, OF NEWARK. NEW J ERSEY.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 774,450, dated November 8, 1904.

Application filed March 15, 1904:.

To all whom it may concern.-

Be it known that 1, LoUIsPnRoTTI, asubject of the King of Italy, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of refrig erators represented by the one shown in my prior patent, No. 746,739, issued December 15, 1903; and the objects of this invention are to provide a householdrefrigerator into which the ice can be easily inserted or supplied at the bottom of the refrigerator and to allow of it to be automatically raised to the top upon closing the front door of the refrigerator, thus avoiding the necessity of lifting the ice cake by hand, and to secure a construction by which the contents of the refrigerator can be reached from either the front or sides thereof.

The invention also relates to some other im{ provements which may be referred to hereinafter in connection with the description of the working parts.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 shows a front view of my refrigerator; Fig. 2, a top view thereof with the top cover removed. Fig. 2 is an enlarged detailed view of the roll applied to the front door of the refrigerator. Fig. 3 is a vertical section of same through line 00 w of Fig. 2. Fig. 4: is a vertical sect-ion of same through line y y of Fig. 2. Fig. 4 is a vertical section through line a" a" in Fig. 1, and Fig. 5 is a vertical section through line 2 z of Fig. 2.

In the drawings, number 2 indicates the body of the refrigerator, and 3 the usual lower front door, providing access to the food-compartment 4:. Above said food-compartment are the bottle-compartments described in my prior patent, No. 7 16,739. In the food-compartment two drawers 5 5, each having shelves Serial No. 198,266. (No model.)

7 6, are provided and adapted to be moved in and out. When the drawers are in their normal position within the food-compartment, their inner walls 33 are located adjacent to each other, leaving a free space 9 between them for the purpose to be hereinafter described. To enable an easy movement of the drawers, the latter may be provided on their bottom with rolls 11, running upon the bot tom 10 of the refrigerator. The side walls 12 of the shelves are shorter than the inner and outer walls thereof, so that when the drawers are withdrawn the food contained therein can be examined or removed from the sides of the drawers or some fresh food can be placed therein. The bottle-compartments 13 13, located one at each end of the refrigerator above the food compartment, have partitions 14: standing at little away from the end walls of the refrigerator and extending to a. certain height upward from the floors 15, cut away between the end walls of the refrigerator and the said partitions, whereby the warm air rising within the food-compartment is allowed to pass and mix with the cold air of the bottlecompartments. The inner walls 16 of these compartments 13 are perforated for the passage of the cold air from the ice-compartment 17, arranged between the two bottle-compartments 13. Said inner walls 16 are removable and shiftable, so that the bottle-compartments 13,according to the requirements,can be made larger or smaller. For this purpose the bottom edges of these walls 16 are provided with dovetail projections 18, one on each end, and corresponding grooves 19 are crosswise or transversely arranged in the floors 15, said grooves being adapted to receive the projections 18 and to serve as guides for the walls 16. .The bottle-compartments are equipped with front doors 1 to allow an easy access thereto. The ice-chamber '17 consists of a suspension-floor 20, adapted to be lowered and raised. Said floor has a hole 21, over which a corrugated plate 13 may be placed to support a cake of ice when put in the refrigerator. This floor 20 is held in position between the two floors 15 of the bottle-comsuspended from a chain 26. Two rails or bars 7 are fixed to the bottom surface of the floor 1 20 and are bent upward at their inner ends. A cross-piece or traverse 28 is attached to the l top ends of the angular rails and has at its 1 center an upward projection or ahook 29 en 1 gaging the chain 26. Said chain is guided over a roll 30, arranged upon the back wall 31 of the refrigerator. In order to cover up i the weight 25, the back wall 31 of the refrigerator may be arranged asadouble wall, with a space 43 between the two parts, as shown in Figs. 2 and 5. The inner part of this double wall 31 supports the guide-roll 30. In order to guide the floor 20 at its upward and downward movement, the following arrangement is provided: The top part 32 of the front wall of the refrigerator is made a little thicker than the rest of it and is provided with cylindrical bores 34. To the front part of the floor, on each end thereof, a tube 35 is fixed, fitting in a tube 36, which tube 36 is guided in the cylindrical bore 34 of the wall 32. These tubes thus telescope in each other and the bores, there being suitable means to prevent their coming out from one another. It will be seen that when the floor 20 is lowered the tubes 35 will move outward from the tubes 36 and the latter from the bores 34, while on the other side the counterweight will rise until the floor has reached the bottom of the refrigerator. When the floor is raised, the tubes will be telescopically shifted into each other and finally adopt the position shown in Fig. 3, in which the floor 20 is at the same level as the floors 15 of the bottleconlpartments. In order to allow of the floor 20 to be lowered and raised simultaneously with the opening and closing of the front door 3 of the refrigerator, a chain 37 is attached to the bottom surface thereof, extending downward to the floor 11 of the refrigerator, where the same is guided over rolls 38 and 39 and is attached to the lower and front end of the door. There may be also a roll 40 provided at this part of the door, to which the front end of the chain 37 is attached and upon which the chain may be adapted to wind up and off. This roll 40 may be made under the action of a spring etl to always turn in a certain direction, and a button &2, projecting from the door outward, may be provided, by means of which button said roll can at will be arrested. It will be obvious that owing to this arrangement the floor 20 will be lowered by opening the door 3, when the roll just now mentioned will be arrested by the impressed button. If, however, it is desired to open the front door of the refrigerator without pulling down the floor 20 of the ice-chamber, it is only necessary to disengage the s above-stated spring-roll by pulling out the button, so that when the door will be opened the chain is allowed to wind off the roll and when the door is closed to wind up the roll. Before the door could be opened in order to insert a fresh cake of ice into the refrigerator the drawers 5 5 must be pulled out, so as to clear the space within the food-compartment.

Any suitable means may be provided to hold the door 3 in its open position. This door, as well as the doors 1 of the bottle-compartments, may have glass windows for the convenience of looking into the different compartments without opening the doors. At the top the refrigerator may be provided with a cover suitably hinged to the back wall, and at the bottom the receptacle receiving the water flowing off when the ice melts may be arranged as a drawer, as shown in Figs. 1, 4, and 5.

Like in the prior patent, there is a drainpipe ll provided, leading from the floor of the ice-chamber into the water-receptacle 42, arranged at the bottom of the refrigerator. This drain-pipe may be fixed to the back wall of the refrigerator and pass through a hole made in the bottom of the icechamber, so as to permit this bottom to be moved up and down.
