FREDERICK C. SCHMIDT, OF BEEVILLE, TEXAS.
REFRIGERATOR.
9d6,332. Specification of Letters Patent. Patented Nov. 29, 1910.
Application filed Noveinber 13, 1909. Serial No. 527,865.To all whom it may concern:
Be it known that 1, FREDERIcK C.
ScinmnT, a citizen of the United States,
residing at Beeville, in the county of Bee
5 and State of Texas, have invented new and
useful Improvements in Refrigerators, of
which the following is a specification.
This invention relates to improvements in
refrigerators.
10 The primary object of the invention is
the provision of a refrigerator in which milk
may be cooled without the use of ice, the
invention comprehending a refrigerator
which consists of a casing, a plurality of
15 pans located in the casing, liquid-absorbent
pads located in the pans, and a reservoir
communicating with the pans.
A further object of the invention is the
provision of a refrigerator of the above
20 stated character which shall be simple, du-
rable and efficient of construction, and which
may be manufactured and sold at a com-
paratively low cost.
With the above and other objects in view,
25 the invention consists in the construction,
combination and arrangement of parts here-
inafter fully described and claimed, and
illustrated in the accompanying drawings,
wherein
30 Figure 1 is a view in front elevation of a
refrigerator constructed in accordance with
my invention. Fig. 2 is a sectional view
taken on a plane extending vertically
through one of the pans and reservoir. Fig.
35 3 is a detail perspective view of one of the
pans. Fig. 4 is a detail perspective of one
of the absorbent pads, and Fig. 5 is a detail
perspective view of one of the flues.
Referring to the drawings by reference
40 numerals, 1 designates the bottom, 2 the top,
and 3 the back of the casing of my improved
refrigerator. The sides of the casing are
not shown in the drawing. The front of the
casing is adapted to be closed by screen doors
45 4 which are hinged to the sides of the casing.
The casing is mounted upon the legs 5, and
at a point below the bottom 1 thereof is a
shelf 6. The shelf 6 is designed to support
drip pans 7 and S. Flues 9 are secured to
50 the back 3 of the casing and extend through
the top 2 thereof, the upper ends of the
flues terminating in cowls 10. The flues 9
are each fully open at one side. Reticu-
lated panels 11 extend across the open sides
55 of the flues. The screen doors 4 and the
flues 9 permit air to circulate freely throughthe casing. Shelves 12 are secured within
the casing, and mounted thereon and upon
the bottom are pans 13. As shown in Fig.
2 of the drawings, each pan 13 is provided 60
on its under side with a water receptacle 14.
The water receptacles 14 communicate with
the pans 13 through the openings 15 formed
in the bottoms of the pans. A reservoir 16
is mounted upon the top 2 of the casing and 65
is provided with a removable closure 17. A
pipe 1S, which communicates at its upper
end with the reervoir 16, extends down
through the casing, the lower end of the
pipe terminating above the drip pan 7. 70
Branch pipes 19 are in open communication
with the pipe 18 and the water receptacles
14. Valves 20 are mounted in the pipe 18
to provide means by which the supply of
water to one or more of the water receptacles 75
14 may be cut off or established. Absorbent
pads 21 are located in the pans 13. Each
pan 13 is provided with a drip pipe 22. The
drip pipe of the uppermost pan 15 dis-
charges into the intermediate pan and the 30
drip pipe of the lowermost pan discharges
into the drip pan 8.
In practice, the reservoir 16 is filled with
water, after which the valves 20 are opened.
When the pads 21 become thoroughly satu- t5
rated with water the valves -23 are closed to
cut off the supply of water to the water
receptacles 14. Receptacles containing the
milk to be cooled are placed in the pans 13
upon the absorbent pads 21. The water car- 90
ried by the pads 21 will absorb the heat of
the milk and the resulting vapor will be car-
ried off through the flues 9. When the water
in the receptacles 14 falls below a certain
level by reason of its absorption by the pads 95
21, the valves 20 are opened to permit the
water to flow from the reservoir 16 to the
water receptacles 14. The reservoir 16, pipe
18, pans 13, and water receptacles 14, may
be drained by opening a valve 23 which is 100
located at the lower end of the pipe 18.
Changes in the form, proportions and
minor details of construction may be made
within the scope of the claims without de-
parting from the spirit or sacrificing any 105
of the advantages of the invention.
Having thus fully described the inven-
tion, what is claimed as new, is:
1. A refrigerator including a pan pro-
vided with a water receptacle and communi- 110
cating therewith through a plurality of
openings in the bottom of the pan, a drip
