BUTTER BOX OR CASE.

SPECIFICATION forming part of Letters Patent'No. 515,258, dated February 20, 1894.

Application filed October 18, 1893.

To all whom. t may concern.:

Be it known that I, CHALMERS L. SIMS, a

cord, in the county of Cabarrus and State of North Carolina, have invented certain new and useful Improvements in Butter Boxes or Cases; 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 saine, reference being had to theV accompanying drawings, and to the letters of reference marked thereon, which form apart of this Specification.

My invention relates to improvements in butter boxes or cases, that is to say a box or case for storing and shipping butter, and the object of my invention is the provision of a casein which the butter can be retained fresh and hard by having the cold air circulate freely around the butter in the entire case; also which will permit the trays to be easily placed in or removed from the case; also which will insure an even circulation of cold air to the butter and which case'will be simple, durable and inexpensive.

The invention consists of a butter case or box embodying novel details of construction, combination and arrangement of parts substantially as herein illustrated, described and specifically claimed.

Figure l represents a perspective view of the case with cover raised. Fig. 2 represents a vertical sectional view of the case. Fig. 3 represents a perspective view of' a slightly modified form of tray, and Fig. 4 represents a detail View thereof.

In the drawings- A designates the box or case having the cover B provided with the close fitting portion C to render the case comparatively air tight. The case is preferably constructed of wood with the walls quite thick. If desired the walls of the case may be double and have a suitable heat non-conducting material B placed between them. In the center of the case is placed the square ice box D which extends to the top of the case and is closed by the cover. The walls of the box may be provided with perforations E to permit the cold air to pass therethrough and a discharge pipe F leads from the bottom of the box through the case to prevent Serial No 488,473. (No model.)

an accumulation of water. In the case are placed a series of sheet metal trays G each having the square opening I-I to iit around the ice box and also having the depending cups J to receive the butter. It is necessary and vitally important that the trays should be supported sufficiently above each otherl to form an air space and to do this I provide the corner uprights K and the central uprights L, the latter being in the form of yokes or bails and thus serving in addition to supports the purpose of handles to permit the easy removal of the trays. The cups are preferably of tapering form which allows a large space around the cups for the cold air to circulate and the supports also leave a space and thus the cold air can circulate to every portion of the trays and thus the but- -ter be always retained hard and fresh. The

wall of the trays may be also provided with perforations to allow the passage of cold air.

It will thus be seen that I provide a shipping and storing case for butter which will accommodate a large quantity; which insures a perfect and even circulation of cold air to all parts of the case; which permits easy .removal and insertion of the trays and which is simple and practical. I also provide the tray with the wall M which forms the cold air chamber N around the cups.

I claim- 1. A butter box or case consisting of the box having the tight iitting cover, the centrally arranged ice box having the discharge pipe leading to the outer air, the trays having the double wall forming a cold air chamber and the cups and litting over the ice box and the supports extending from the upper side of the trays.

2. Abutter box or case consisting of the box proper, the square ice box therein, the trays having the opening to fit around the ice box, the corner supports on the trays and the lcentral supports made in the form of a bail to serve as handles.

In testimony whereof I- aftix my signature in presence of two witnesses.
