CONTAINER Filed April 28, 1939 Raymandfi IN V EN T OR.

ATTORNEYS.

Patented Feb. 17, 1942 STATES FFICE 1 Claim.

This invention relates to a container designed for containing liquids which freeze under freezing temperature, the primary object of the inven tion being to provide a collapsible body held within the container to compensate for the expansion of the liquid during the freezing thereof, thereby insuring against the container being broken by the expansion of the frozen material within the container.

An object of the invention is to provide a device of this character which may be supported in such a manner within the container that the compressible body may be readily observed, to determine the condition of the compressible body.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a vertical sectional View through a container equipped with an expansible body, constructed in accordance with the invention.

Figure 2 is a transverse sectional View taken on line 2-2 of Figure 1.

Figure 3 is a vertical sectional view through a container equipped with an expansible body designed to float within the container.

Referring to the drawing in detail, the container is indicated generally by the reference character 5, and as shown is provided with an inlet pipe G, and an outlet pipe I.

The bottom of the container is formed with an opening, the wall of which is threaded to accommodate the plug 8, by means of which access to the interior of the container may be had.

As shown, the opening is formed in such a way as to provide a shoulder 9 against which the flange ill of the neck I! is held, by the action of the plug 8, which is shown as positioned thereagainst.

The expansible body IQ, of which the neck ll forms a part, is preferably constructed of rubber, and filled with air to be compressed by the expansion of the liquid in the container, freezing.

In the form of the invention as shown by Figure 3 of the drawing, the expansible member or body i3 is placed within the container, to float to the top of the container, as shown.

The body It in this form of the invention is also constructed of rubber material and filled with air to be compressed, due to the expansion of the liquid freezing within the container.

The reference character l4 designates the cover for the container, which may be held in position by any suitable means.

From the foregoing it will be seen that due to the construction shown and described, a space is provided at all times within the container, to compensate for the expansion of the material freezing. It is obvious that as the material in the container freezes, pressure will be directed to the expansible body, compressing the air in the body, and compensating for the expansion, thereby relieving the walls of the container of undue strain which, under ordinary conditions, would break or rupture the container to cause the same to leak.

What is claimed is:

The combination with a receptacle having an opening in the bottom thereof and having inlet and outlet pipes connected with the receptacle and disposed in a horizontal line drawn through the center of the receptacle, of a substantially shallow circular hollow body portion constructed of rubber material, fitted within the receptacle, through the opening in the bottom of the receptacle, a neck forming a part of the body portion through which air is directed to the body portion inflating the body portion, said neck being fitted within the opening in the bottom of the receptacle, the upper surface of the hollow body portion being spaced an appreciable distance below the direct line of flow of Water through the pipes and receptacle, and means for removably securing the neck of the body portion, within the opening in the bottom of the receptacle.
