Improved Means for Cooling and Filtering Liquids.
I, FRANCIS OAKLEY, of Newport, in the County of Newport, and State of Rhode
Island, United States of America, Gentleman, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to an improvement in coolers used for the purpose of cool-
ing beer, ale, water or other liquids, as they pass from the barrel or other recep-
tacle, through the pipe to the faucet.
The object of the invention is to provide a means of cooling and filtering the
liquid, as hereinafter set forth, reference being had to the accompanying drawings,
which with the letters of reference attached thereto, form a part of this specification,
and in which drawings,
Fig. 1 is a perspective view of a cooler and attachments with parts broken away.
Fig. 2 is a vertical sectional view through the cooling box, and-
Fig. 3 is an enlarged detail view of the filters showing the same removed from
the receptacle designed to contain the same, the screen and filter-holders being
shown in vertical section.
In the usual manner of drawing beer, ale and other liquids, an air pump or some
other means is employed for the purpose of forcing the liquid through the faucet,
and in order to more particularly illustrate my cooler "A," I employ an air pipe n,
leading from the pump c, to the barrel S. In carrying out my improvement I
do not, as heretofore, cool the liquid by a series of coils of pipe usually conveying
the liquid from the barrel through the said series of coils packed in ice, to the
faucet, for the reason, that the deposit of sediment from the liquid collects in the
coils of pipe, thereby making the liquid unhealthful and offensivo
within a short period of time. I obviate this difficulty by my cooler A,
acting as a settling tank, and employ the cover B to attach to the neck of my
cooler, by means of a thread ), or other suitable detachable fastening, and to more
particularly illustrate my cooler, I employ the thread j to fit the neck a; it being
necessary to make an air-tight connection, I use a washer y, of rubber or some
other resilient material, and to clean the cooler I disconnect the supply pipe c, at
the union u. I then detach the cover B from the neck a, by means of the nut c.
I then remove the strainers h-h, and filters dd when the hand can then be
inserted through the neck a, and the inside of the cooler can be readily cleaned.
I also provide a regulating pipe g, with a coupling m, to connect the pet cock t,
that the gases generated in the cooler may be released by means of the pet cock t,
wholly or partially at will, thereby providing a means of drawing the liquid from
the faucet i, as required.
I further employ a filter d, made of felt or other suitable material, for the pur-
pose of filtering the liquid as it enters the cooler and in combination therewith
I employ a wire screen h, or some other porous material for the purpose of keeping
the felt d, in a flat position on the seat f
I further employ an outlet pipe b, with coupling m, for the purpose of drawing

page_text: the cold liquid from, or near the bottom of my cooler A, pipe b connecting with
the faucet i, by the coupling m.
I also provide feet rr, to the bottom of my cooler, in order to elevate the cooler
from the floor of the ice-box p, the cooler thereby receiving the cold radiation of
water, coming from the ice z, the waste water from the ice making its exit from
the box p, by means of the waste-pipe w.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
In a cooler, the combination with the box A mounted on suitable legs within
an ice-box, the pipes b, and g, communicating with the interior of said box,
the internally threaded neck portion of the box and shoulder f, the cap B with
integral nut extension c, which is centrally apertured, the pipe e, having screw-
threaded connection with the said cap in said aperture, of the alternately disposed
screens and filters h and d respectively, held within the said neck-portions and
between the shoulder f, and cap B, and the pump and connection with the supply
tank and box A, all substantially as shown and described.
