IRA A. LIVINGSTON, OF MINNEAPOLIS, MINNESOTA.
IMPROVEMENT IN REFRIGERATORS.
Specificationforrning part ot Letters Patent No. 129,599, dated July 30, 1872.
SPECIFICATION.
To all whom 'it may concern: Be it known that I, IRA A. LIVINGSTON, of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in a Butter-Cooler or Refrigerating-Case, for shipping or transporting butter to market in the hot or summer season; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this speciication, in which- Figure 1 represents a vertical section across the center, longitudinally, of the case, showing the double walls, the iceboxes, the waterreceivers, ventilators, and the butter-chamber, with all the covers for the apartments. Fig. 2 represents a top view with all but one of the ice-boxes removed, looking in on the cleated bottom, and showing the Ventilating-cleats or guiding and supporting bars to the chambers. My invention vrelates to portable refrigerators; and it consists in the construction, ar rangement, and combination of the chambers, ventilators, coolers, guide and supporting bars, cleats, &c., which will be more fully`described, referring to the drawing and the letters of reference marked thereon.V
'.lhe four sides of my coolingbox or refrigerator for transporting butter are made with thick outer walls or boards A A, and thinner boards a a for the inner walls or lining, Ileaving an air-space, b b, between them, which, if desirable, may be filled with any light nonconductor of heat, in the usual manner. The
bottom board B, being single, is cut with sunken grooves c c at right angles, in order to have a circulation of air under the chambers. The
with perforated bottoms ff, on which the ice is supported, allowing the water to drip through into the spaces F F below, where it is kept cool and separate from the ice, Svc. Through the ends or walls A A are tubes e e, which connect with the ice-boxes E E to allow the air to circulate in and out under the cleathandles Gr Gr. The butter-chamber D and also the ice-boxes E E. have wooden lids or covers H, fitted c1ose, to exclude the air from the top. They are provided with cleat-handles h h to replace and remove them with, there being sufficient space for them between the chambers and the cover I, which is also made of double' thickness, leaving a space, i, be-
tween the boards the same as the sides of the box A A. v
The advantages of my butter-cooler or refrigerator for shipping or transporting butter, &c., are that it can be made very light and portable, is easily kept clean and sweet, will retain small quantities of ice a long time, and deliver butter lin market in as fine condition as when taken from a spring or. icelhouse.
What I claim as my invention, and desire to secure by Letters Patent, is-
The recessed bottom B, with right-angle grooves o c and the vertical Ventilating cleatguides d d, in combination with the ice-boxes E E with their ventilatin g-tubes e e, the waterreservoirs F F, and the butter-chamber D, all having close-fitting covers H H, when all the parts are arranged within a double-walled portable box or case A, substantially in the manner as herein shown and described, for the purposes set forth.
In testimony whereof I hereunto subscribe my name.
IRA A. LIVINGSTON.
