UNITED STATES PATENT OFFICE OBADIAH MARLAND, OF BOSTON, MASSACHUSETTS.

INIPROVED REFRIGERATING DISH-COVER.

Specification forming part of Letters Patent No. 111.228, dated January l2, 1864.

To @ZZ whom, it may concern:

Be it known that I, OBADIAH MARLAND, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved Refrigerating Dish-Cover, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part ot' this specification, in which- Figure lis a perspective view ot` my improved dish cover as applied to a butterdish; Fig. 2, a vertical section through the same; Fig. 3, an underneath view of the cover.

My invention consists in constructing a dishcover with a reservoir or receptacle for holding ice, so arranged as to form an air-space between the reservoir and the cover, which is to be placed over dishes containing butter, fruit, ice-cream, or other articles for the table which are required to he kept cool, thus preventing the water produced by the melting of the ice from coming into contact with and injuring the article in the dish-an objection which has heretofore prevented the use of ice on jellies, fruit, and various other articles.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have'carried it out.

In the said drawings, A represents a metallic dish-cover as applied to a dish for containing butter. B is a box or receptacle of the form shown in Fig. 2, made of a less diameter than the interior of the cover A, so as to form an air-space between the two. In the upper part of this box is an opening through which the ice is introduced, and this opening is closed by a cap, C. The box B has projecting from its lower edge three ledges, a, which slide over corresponding projections or ledges,

b, on the inside of the cover A, by which means the box B is retained in place in the upper portion of the cover. One of the ledges b is turned up at 4, as shown dotted in Fig. 2, forming a stop against which one of the ledge a will strike and prevent the box B from being turned too far. It is also slightly turned up at the other end at 5 to prevent the ledge a from sliding back until it is raised sufficiently to clear it. c are projections on the under side of the loox B to prevent the fingers from slipping when the box is turned. When it is desired to remove the box B, it is slightly raised by the hand and then turned back until the ledges c slide oif the ledges b on the interior of the cover, when it can be taken out and refilled with ice.

I do not limit myself to the use of metal as a material for my improved dish-cover, as it is obvious that it may be constructed equally as well of earthenware or any other suitable material.

I have found in practice that with the reservoir B filled with ice a plate of butter or other article will be kept at a temperature ot' about 40 Fahrenheit for a period of nearly five hours, the temperature outside being 7 5 Fahrenheit.

iVhat I claim as my invention, and desire to secure by Letters Patent, is-

The within described refrigerating dishcover, with its reservoir or receptacle B for containing ice, arranged and operating substantially as described, for the purpose set forth.
