VIVAAL DI MUTTA
Improved Refrigerator.
DAVID BURNESS WALKER Fish Curer Poynernook Road Aberdeen. I do
hereby declare the nature of this invention to be as follows:-
=;
A strong, wooden, watertight box, lined all around with non conducting
material.
Inside this box is an iron or metal tank four inches less all around than the box,
and raised from the bottom of the same. Between the two is put ice and salt, or
refrigerating chemicals, which causes the air in the tank to come to and maintain a
very low temperature. By having the wooden box tight all the cold is extracted
from the melted ice when the water is run off by a pipe.
Dated this Ninth day of October 1895.
I, DAVID BURNESS WALKER, of Poynernook Road, Aberdeen, Fish Curer, 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 improved refrigerator which may be used by fish-
mongers, butchers, hotel-keepers and others for keeping anything of a perishable
nature, or in summer time for keeping things cool; said refrigerator may be made
portable or as a fixture.
In carrying out my said invention as shown in longitudinal section Figure 1, and
cross section Figure 2, of the accompanying drawings, I employ or construct a
strong wooden box A having its joints so formed as to make it watertight; the
said box is provided with a hinged lid B, having a hinged service lid or portion C,
and also suitable feet or supports a. The said box A is lined all round with a non-
conducting material.
Inside the said box A, 1 place a metal tank or box D having a service opening
or lid E; said tank D being of such a size as to leave a space, between it and the
interior of the wooden box A, of about four inches, into which space I place ice
and salt, or other refrigerating chemicals, so as to cause the air in the tank D to
come to aud to be maintained at a very low temperature. The refrigerating
material is placed below, around and partly above the tank D (the service lid E
only being left uncovered) and owing to box A being made watertight, all the cold
is extracted from the refrigerating material or materials. When ice is employed
I preferably provide the box A with an outlet or pipe so as to enable the melted
ice or water to be run off.
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 :-
1st. The general arrangement, construction and combination of the various parts

page_text: constituting my improved refrigerator, substantially as herein before described and
shown in the accompanying drawings.
2nd. In refrigerators for preserving perishable goods, mounting the metal box
or tank D within the wooden box A, in such a innnner as to leave a space below,
around and above the said tank for containing refrigerating inaterials or chemicals,
all in the manner and for the purposes as hereinbefore described and shown in the
accompanying drawings.
