HARRY HALL, OF HUNTINGDON, PENNSYLVANIA.

REFRIGERATOR.

Applicatien filed umh 25,1898.

To all whom it may concern.-

Be it known that I, HARRY HALL, a citizen of the United States, residing at Huntingdon, in the county of Huntingdon and State of Pennsylvania, have invented certain newand useful Improvements in Refrigerators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in refrigerators, and especially to a rotary cylindrical portion which is mounted partially within the refrigerator and contains a series of shelves upon which articles may be carried, which cylinder is adapted to make a partial rotation on its vertical axis, whereby access may be had to the shelves, while the opening leading from the refrigerator into the cylinder part is shut off, and when the cylinder is closed the cold air from the cylinder is allowed to circulate freely within the cylinder, while that portion of the latter which is exposed to the outside atmosphere is provided with a suitable packing to retain the cold within the cylinder.

More specifically the present invention resides in the mounting of a cylinder carrying shelves partially within a refrigerator, one side of which cylinder is cut away to allow access to be had to the shelves mounted on the vertical post of the cylinder when the cylinder is turned so that its cut-away portion comes outside of the refrigerator, the outer surface of the wall of the cylinder being adapted to fit snugly against the concaved surface of the partition between the cylinder and the refrigerator, whereby the opening from the refrigerator into the cylinder is closed tightly before access can be had to the interior of the cylinder as it is turned upon its axis, suitable stops and packings being provided within the casing in which the cylinder rotates to limit its movement and to prevent the escape of any of the cold within the refrigerator.

To these ends and to such others as the invention may pertain the same consists, further, in the novel construction, combination,

and adaptation of parts, as will be hereinafter more fully described and then specifically defined in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference markedthereon, form a part of this application, and in which- Figure 1 is a cross-sectional view through the refrigerator, showing the cylinder closed or in such a relation that the cold from the refrigerator will circulate within the cylinder containing the shelves upon which the articles are held which are desired to be kept cooled. Fig. 2 is a similar view showing the cylinder turnedso that access'may be had from the outside to the contents of the cylinder, and Fig. 3'is a front elevation.

Reference now of a refrigeratorgvhich has a portion cut away, as at 13, and has the inwardly-curved wall A, forming a partition between the same and the inner part of the refrigerator. This wall has an opening 0, through which the cold from the refrigerator is allowed to escape into the recessed portion. Mounted vertically in the said recessed portion is a post D, which has provided thereon a series of shelves E and provided with a suitable top D and bottom D and a cylindrical casing G, which extends about half -way around the base and the top described, which cut-away portion is allowed for the purpose of having ready access to the shelves when the cylinder is turned so that the cut-away portion comes outside the refrigerator. The wall of the said cylinder is preferably provided with a suitable packing O, as illustrated, and when the cylinder is turned to assume the position shown in Fig. 1 of the drawings access to the cylinder from the outside is shut off and communication is afiorded between the refrigerator and the interior of the cylinder carrying the shelves through the openings 0. Stops K are provided which limit the rotary movement of the cylinder, and suitable packings O are disposed at different locations on the partition separating the recessed portion from the interior of the refrigerator and against which the outer circumference of the shell of being had to the details of the drawings by letter, A designates the Wallthe cylinder is adapted to bear snugly to prevent the escape of the cold and the ingress of the outside atmosphere. It will be noted from the drawings that the outer circumference of the shell of the casing bears snugly against the concaved surface of the partition between the recessed portion and the interior of the refrigerator and shuts 01f or closes the opening C when the cylinder is rotated and before the cut-away portion of the cylinder is brought so that access may be had to the interior of the cylinder from the outside.

I am aware that it is common in the art to construct refrigerators having swinging c10- sures which are adapted to fold back Within the refrigerator for the purpose of partially shutting off the escape of the cold from the refrigerator when access is to be had to the vessel carried within the folding part. Hence I make no claim for such a construction.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-- In a refrigerator, the combination with the rotatable cylinder mounted vertically in a recessed portion thereof, said recess having a concaved wall with an aperture leading into the interior of the refrigerator, the cylinder having a portion of its circumference cut away, packing-strips seated in the concaved surface of the recess-wall, the outer circumference of the cylinder being adapted to swing against the packing-strips as it is turned back into the recess of the refrigerator and close air-tight the aperture in the refrigerator, and when the shell of the cylinder is swung out, to open the aperture leading from the refrigerator to the interior of the cylinder, the packing-strips adjacent to the edges of the recess forming an air-tight contact with the circumference of the shell, as shown and described.

In testimony whereof I have affixed my signature in presence of two witnesses.

HARRY IIALL.
