WILLIAM P. WILLSON, OF vAJR-LINGITQN, VERIVIONT, ASSIGN'OR TO WILLIAM E. yKDlDER OF KALAMAZOO, MICHIGAN.
REFRIGERATOR.
Application led August 20, 1923. Serial No. 658,475.
T all whom t may concern:
Be it known that I, WILLIAM I). WrLLsoN, a citizen of the United States, residing at Arlington, county of Bennington, State of Vermont, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.
This invention relates to improvements in refrigerators. v
The main objects of this invention are:
First, to provide an improved refrigerator which .is highly eflicient in the preservation of food, the air in the provision chamber boing kept dry and at satisfactory temperature for the purpose.
Second, to provide an improved refrigerator which is very economica-l in the consumption of the refrigerant.
Third, to provide an improved refrigerator having these advantages which is very easily supplied with the refrigerant.
Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.
I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly dened and pointed out in the claims.
A structure which isa preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:
Fig. I is a front elevation of myimproved refrigerator.
Fig, II is a vertical central section through my improved refrigerator, partsbeing shown in full lines for conveniencein illustration. l
Fig. III is a horizontal section on a line corresponding to line 3 3 of Fig. II.
Fig. IV is a detail vertical section on a line corresponding to line 4--4 of Fig. II.
In the drawing similar' reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.
Referring to the drawing, I provide a suitable casing which, in the structure illustrated, comprises the outer wall 1 preferably of wood, an inner wall or lining of metal 2 and an insulating filling L3 between them. The casing is provided with` provision chamber doors 4 at the front and a refrigerant chamber door 5 at the top.
lAt the bottom of the casing is a pan 6 having'A a drain opening 7 The refrigerant chamber comprises a bottom portion 8 and a vertical portion '9, the lining or inner wa'll '3 of the casing constituting the outer walls of this refrigerant chamber. The inner wall 3 has a pan-like portion 1Q at the bottom disposed within the pan G, being supported therein by rthe cross pieces 11 formed of sheet metal and having offsets 12 therein supporting the refrigerant chamber with its bottom in a spaced relation to the bottom of the pan 6. I liave'not shown Athe seams of these walls as the structural details thereof form no part of this invention.
The inner wall 13 of the refrigerant chamber is inclined so that the refrigerant chamber expands downwardly. This prevents the refrigerant, which is preferably chipped ice with a suitable chemical, from becoming clogged and should it become frozen tothe walls, it is readily detached and .forced downwardly by `a tamper bar or the like.
The refrigerant chamber is adapted to contain a liquid and has-a drain pipe 14 provided with a valve 15 and a liquid'level pipe 16 which projects upwardly Within the refrigerant chamber', its inner end being preferably curved to prevent clogging and also providing a trap, preventing the entrance of air when the liquid level reaches the end of the pipe 16.
The provision chamber .17 is provided with a vertical wall 18, spaced from the inner wall 13, and a bottom wall 19 spaced from the top wall 2() of the horizontal portion of the bottom portion of the refrigerant chamber, thereby providing an air passageA 21 which is open at 22 to the top of the provision chamber and at 23 to the bottom thereof.
The walls 18 and 19 are imperforate so that the air must circulate through this passage 21 from top to bottom and in such circulation comes in contact with the wall 13 of the refrigerant chamber.
A wall 13 extends forwardly from the upper end of the wall 13 providing a hopper 24 facilitating the lling of the refrigerant chamber. When the door or cover 5 is opened the refrigerant may be dumped into the hopper and pushed therefrom into the refrigerant chamber.
An opening 25 connects the air passage with the bottom pan 6, so that should any moisture accumulate in the passage, it will pass into the pan. However, when the refrigerator is kept properly supplied with the refrigerant, there is little or no moisture to drain away as it will collect in the form of frost on the walls 13 and 20.
My improved refrigerator is very eiiicient, it being possible to maintain the desired temperatures for food preseravtion, and further,
, the temperature in the provision chamber is quite uniform, the air being eectively cir culatcd from top to bottom thereof and being brought into contact with the refrigerant chamberwalls is quickly cooled and any excess moisture therein is deposited in the form of frost on the walls of the refrigerant chamber.
I have not attempted to illustrate and describe certain modifications and adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.
Having thus described my invention, what I claim as new and desire to secure by Lety ters Patent, is
1. A refrigerator comprising a casing provided with a provision chamber door at the front and a refrigerant chamber door at the top, a bottom pan disposed in the bottom of said casing and provided with a drain open;
ing, a refrigerant chamber adapted to holdy a liquid and comprising a horizontal bottom portion disposed within said bottom pan and a vertical portion disposed at the rear of said casing, a wall extending` forwardly from the upper end of said refrigerant chamber inner wall and constituting a hopper facilitating the charging of said refrigerant chamber, and a provision chamber comprising a rear wall spaced from said inner wall of said refrigerant chamber and a bottom wall spaced from the top wall of the horizontal portion of said refrigerant chamber providing an air circulating passage between such refrigerant chamber walls and provision chamber walls, the upper end of said rear wall being spaced from the said hopper bottom wall and the front end of said bottom wall being spaced from the front wall of the casing providing circulat-v ing openings, said circulating p assage being otherwise closed to said provision chamber,
there being a drain opening from said circulating passage to said bottom pan, said refrigerant chamber being provided with a liquid waste pipe having its inlet in spaced relation to the bottom thereof.
2. A refrigerator comprising a casing provided with a provision chamber door at the front and a refrigerant chamber door at the top, a refrigerant chamber comprising a horizontal. bottom portion and a vertical portion disposed at the rear of said casing, a wall extending forwardly from the upper end of said refrigerant chamber inner wall and constituting a hopper facilitating the charging of said refrigerant chamber, and a provision chamber comprising a rear wall spaced from said inner wall of said refrig erant chamber and a bottom wall spaced from the top wall of the horizontal portion of said refrigerant chamber providing an air circulating passage between such refrigerant chamber walls and provision chamber walls, the upper end of said rear wall being spaced from the said hopper bottom wall and the frontend of said bottom wall being spaced from the front wall of the casing providing circulating openings, said circulating passage being otherwise closed to said provision chamber.
3. A refrigerator comprising a casing, a bottom pan disposed in the bottom of said casing and provided with a drain opening, a refrigerant chamber adapted to hold a liquid and comprising a horizontal bottom portion disposed within. said bottom pan and a vertical portion, and a provision cham-A ber comprising a vertical wall spaced from a vertical wall of said refrigerant chamber and a horizontal bottom wall spaced from ber providing an air circulating passage between such walls,l said passage being open at the top and bottom thereof to said proprovision chamber but otherwise closed thereto, there being a drain opening from said circulating passage to said bottom pan, said refrigerant chamber being provided with a liquid waste pipe having its inlet in spaced relation to the bottomthereof.
