WILLIAM WILEY LANGHAM, OF CALDWELL, TEXAS, ASSIGNOR OF ONE-HALF TO T. F.
GILLEY, OF CALDWELL, TEXAS.
COOLER.Specification of Letters Patent.
Patented Apr. 4, 1911.
Application filed May 9, 1910. Serial No. 560,308.
To all whom it may concern:
Be it known that I, WnILAM WILEY
LANGIIAM, a citizen of the United States of
America, residing at Caldwell, in the county
5 of Burleson and State of Texas, have in-
vented certain new and useful Improve-
inents in Coolers, of which the following is
a specification, reference being had therein
to the accompanying drawing.
0 This invention relates to apparatus for
keeping perishable articles cool, and has
especial reference to apparatus for keeping
milk and water cool in which the contents of
the cooler are preserved by reducing the
15 temperature by the evaporation of water.
The invention has for its object to provide
an improved apparatus of this character by
means of which perfect ventilation and air
circulation will be obtained, and the articles
20 to be preserved contained in the cooler kept
cold and absolutely free from dampness.
Another object of the invention is to pro-
vide a cooler of this kind by means of which
the entire surface of the water tank is in di-
25 rect contact with the inside cold air, thereby
automatically keeping the water in the tank
cold.
The invention further has for its object to
keep the cold water in a cooler from being
30 exposed to the outside warm air.
The invention further has for its object
to maintain a constant circulation of cool
water through the cooler.
The invention further has for its object to
35 prevent warm air from rising into the cooler.
With these and other objects in view, the
invention consists in an improved cooling
apparatus and in details thereof, constructed
and arranged as hereinafter set forth and
40 claimed.
Referring to the accompanying drawings:
Figure 1 is a perspective view of a cooler
constructed in accordance with this inven-
tion. Fig. 2 is a view of the upper portion
45 of the cooler, partly broken away, and in
vertical section on the line x-x of Fig. .
Fig. 3 is a detail view in horizontal section
of a corner of the structure. Fig. 4 is a de-
tail view in perspective, partly broken away,
50 of a portion of the upper part of the cooler.
Fig. 5 is a view in vertical section of the
lower portion of the cooler on the line y-y
of Fig. 1.
The cooler, constructed in accordance with
55 this invention, consists of an open uprightstructure, formed with vertical posts or up-
rights 1, preferably of metal and hollow for
the sake of lightness, and having its lower
portion mounted on and elevated above the
lower ends of the uprights 1, and preferably 60
formed of sheet metal bent up to form an
outside gutter 2, and an inner hollow ele-
vated central portion, 3, open at its bottom
and having its sides provided with air-ven-
tilating holes, 4. The gutter portion 2 is 65
provided with a suitable discharge pipe, 5,
having a cork or valve, 5', by means of which
water collected in the gutter 2 may be drawn
therefrom. At the upper ends of the up-
rights 1 is mounted a gutter portion, 6, pref- 70
erably formed of sheet metal, and having a
hollow central elevated chamber 7, having its
sides provided with air-circulating holes? 8,
the top and bottom of the chamber 7 being
open, and a water-cooler, 9, having a bead, 75
9', at its lower end, whereby the water tank
9 may be seated in the top of the chamber 7.
The water tank 9 is provided with a remov-
able cover, 10, and a faucet 11, and suitable
handles 12, by means of which the tank 9 80
may be lifted out of the chamber 7.
Secured to the posts 1 at intervals be-
tween the upper and lower portions of the
structure, are shelves 13 for supporting the
things to be cooled, each shelf 13 being pro- 85
vided at its edge with a gutter 14 for carry-
ing off any water or other liquid from the
shelf. The entire structure from the top
gutter to the bottom gutter is covered with
a curtain 15, of suitable material which is a 90
good conductor of water, the upper edge of
said curtain extending over the edge of the
top gutter and depending in the same and
suitably secured thereto by clamps 16, or
other suitable means. The upper gutter 95
contains only enough water at one time to
keep the curtain around the cooler wet, so
there will be only a very small body of water
exposed in the upper gutter to the open air.
The curtain will draw by capillary attrac- 100
tion the water out of the upper gutter to
the lower gutter and keep the water con-
stantly circulating. The lower central por-
tion 3, the top of which forms a shelf, is
preferably covered with pasteboard, 3', to 105
keep it cool and prevent it from becoming
warmed by the outside warm air.
It will be seen that by means of a cooler
constructed as hereinbefore described, the
circulation of water over the curtain will 11J988,882.
