IMPROVEMENT IN REFRIGERATORS.
Specification forming part of Letters Patent No. 209,934, dated November l2, 1878; application filed v May 23, 1877.
Be it known that I, ROBERT SPENCER, of Columbus, in the county of Franklin vand State of Ohio, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others vskilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in refrigerators; and it consists in forming an offset on the sideof a large cooler or refrigerator, in which small articles are kept, there beinga sliding door between the two, which is operated by the door of the offset, so as to prevent the cool air from the refrigerator from escaping when the offset is opened, as will be more fully described hereinafter.
The accompanying drawing represents my invention. y
a represents a large refrigerator or cooler,
.such as is used by butchers to keep their mea-t in, and which may be of any size, shape, or construction desired. On one side of this cooler, at its bottom, is built the offset c, of suitable size, which is provided with a falling cover, d, and the shelves e. The wall of the cooler is cut away to a suitable extent where it forms the back of this offset, so that the cool air from the refrigerator will lill the offset and preserve articles placed in it as well as in the cooler itself. 111 this offset are to be kept small perishable articles, such as are frequently wanted, so that they can be gotten at any moment without having to open the door of the cooler itself, thereby letting warm air and liies in.
Sliding in suitable guides inside of the cooler, so as to snugly close the opening be tween the offset and the cooler, is the door g, which has a rope attached to it, and this rope passes up through a hole in the roof of the cooler, over one or more pulleys, h, and passes down'and is fastened to the top of the cover d. As the cover and the door nicely balance each other, when the cover is raised the door closes the opening, and when the cover is closed the door is raised. Thus it will be seen that when the door of the offset is raised all communication wit-h the cooler is shut oli', so that no Warm air or flies can getinto the cooler, even should the oset be left open for days, and that as soon as the cover is closed the cool air of the cooler at once Hows in.
Having thus described my invention, I claiml In a refrigerator, the combination of the cooling-chamber a, offset c, door d, connecting rope or chain, slide g, and pulleys h, the door d and slide g being so connected that when the door is raised or lowered upon its hinges the slide will move vertically down or up, whereby warm air is prevented from passing into the chamber a when the door d is raised, substantially as shown and described.
In `testimony that I claim the foregoing I have hereunto set my hand this 10th Aday of May, 1877.
