PERRIE HAY, (NOW BY MARRIAGE PERRIE DAVIS,) OF MINERAL WELLS, TEXAS.
MILK-COOLER.Specification of Letters Patent.
Patented June 2, 1908.
Application filed December 21, 1906. Serial No. 348,959.
To all whom it may concern:
Be it known that I, PERRE I-AY, a citizen
of the United States, residing at Mineral
Wells, in the county of Palo Pinto and State
, of Texas, have invented a new and useful
Milk-Cooler, of which the following is a speci-
fication.
This invention relates to milk coolers and
has for its object to provide a'comparatively
10 simple and inexpensive device of this charac-
ter by means of which the milk or other con-
tents of the cooler may be maintained at a
uniformly low temperature without the em-
ployment of ice or other refrigerant.
15 A further object of the invention is to pro-
vide a receptacle adapted to be suspended
from a suitable support and provided with a
plurality of food-supporting trays or com-
partments, said receptacle being inclosed in a
20 casing or fabric jacket on which is deposited
a small stream of water so that the evapora-
tion of the water will cool the contents of
said receptacle.
A still further object of the invention is to
25 generally improve this class of devices so as
to increase their utility, durablility and effi-
ciency.
With these and other objects in view the
invention consists in the construction and
30 novel combination and arrangement of parts
hereinafter fully described, and illustrated in
the accompanying drawings, it being under-
stood that various changes in form, propor-
tions and minor details of construction may
35 be resorted to within the scope of the append-
ed claims..
In the accompanying drawings forming a
part of this specification: Figure 1 is a per-
spective view of a cooler constructed in ac-
40 cordance with myinvention. Fig. 2 is a simi-
lar view with the fabric jacket removed, one
of the doors of the upper and lower compart-
ments being shown in open position.
Similar numerals of reference indicate cor-
.45 responding parts in all of the figures of the
drawings.
The improved device comprises a support-
ing frame consisting of parallel side bars 5 to
which are soldered, riveted or otherwise se-
50 cured a plurality of spaced food-containing
trays 6.
Arranged at the upper end of the frame and
secured in any suitable manner to the side
bars 5 is a compartment or chamber .7 the
55 cover 8 of which is substantially conical inshape, as shown and serves to connect the
upper ends of the side bars 5.
The compartment 7 is provided with a pair
of outwardly swinging pivoted doors 9 one of
which is provided with a suitable catch 10 60
adapted to engage a keeper 11 secured to the
opposite door when said doors are moved to
closed position.
Disposed at the lower -end of the frame and
secured in any suitable manner to the side 65
bars 5 is an auxiliarly compartment 12 the
top of which is preferably formed by the ad-
jacent food-supporting tray 6, said compart-
ment being provided with pivoted doors 13
similar in construction to the doors 9. 70
Secured to the apex of the cover is a rod
or post 14 on which is mounted a water sup-
ply tank 15, the latter being preferably rein-
forced and strengthened by a bead or flat
strip of metal 16 which extends transversely 75
across the top of the tank and down both
sides thereof.
Secured to the bar 16 is a hook 17 by
means of which the cooler may be suspended
from a tray or other suitable support, and so
pivotally mounted on the bar 16 is a closure
18 so that water may be conveniently intro-
duced into the tank 15.
. The frame is preferably incased in a fabric
jacket 19 one end of which engages the con- 85
ical shaped top or cover 8 and is secured to
the post or standard 14 by a draw string 20
while the opposite end thereof is secured to a
ring or flange 21 carried by a rod section 22
depending from the bottom of the compart- 90
ment 12. The food compartment or casing
19 is split longitudinally and provided with
one or more eyelets 23 in which is threaded a
cord 24 for securing the adjacent longitudi-
nal edges of the jacket. 19 in contact with 95
each other.
Depending from the bottom of the tank 15
and bearing against the post 14 are depend-
ing nozzles 25 for feeding the water from the
tank 15 to the jacket 19, said nozzles being 100
provided with suitable stop cocks or valves
26 whereby the quantity of water from the
tank may be regulated at will.
It will thus be seen that the water by cap-
illary attraction will follow the course of the 105
fabric jacket so that the latter becomes thor-
oughly soaked and by the evaporation of the
water constantly cools the contents of the
trays or compartments.
In order to obtain access to the upper or 110No. 889,681.
