THERMOS-BOTTLE ATTACHMENT.
, Specification of Letters Patent.
Patented May 31, 1921.
Application filed. September 10, 1920. Serial No. 409,433.
T 0 all whom it may concern:
Be it known that we, CoNNIn H. WILsoN and CHARLES G. LEE, citizens of the United States, residing at Asheville, in the county of Buncombe, State of North Carolina, have invented a new and useful Thermos-Bottle Attachment, of which the following is a specification.
This invention relates to an attachment for use in thermos bottles and the like during the filling of the same with hot or cold liquids, the said attachment being designed to equalize the conduction of heat from one end to the other of the container, thereby to prevent breakage due to unequal temperatures resulting from the sudden contact of hot or cold liquid with the container.
The invention is more particularly an improvement upon the structure disclosed in Patent #1,3%2,883 issued to us on June 8th 1920.
One of the objects of the invention is to provide an attachment in the form of a coil which can be easily placed in and removed from the container, can be readily cleaned, will not corrode or tarnish, and can be manufactured cheaply in a single piece.
lVith the foregoing and other objects in view which will appear asthe description proceeds, the invention consists of certain novel details of construction and combina tions of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.
In the accompanying drawings the preferred forms of the invention have been shown.
In said drawings Figure 1 is a side elevation of the device, the container in which it is insertible being shown by dotted lines.
Fig. 2 is a plan View.
Fig. 3 is an elevation of a modified form.
Referring to the figures by characters of reference, 1 designates an elongated coil of aluminum wire or wire of other material which will not corrode or tarnish. This coil is of uniform diameter except at one end where it is rounded or tapered, as shown at 2, the convolutions forming this end por- Thus it will be seen that when liquid, whether hot or cold,
is poured into the container the wire coil will act as a conductor so that the entire container will expand or contract uniformly, thereby preventing cracking which would otherwise occur. As soon as the container has been filled the attachment can be removed. The device can obviously be cleaned readily. Instead of providing the projecting end or arm 4 the large end of the coil can be pointed, as shown at 6 in Fig. 3, and seated within a stopper of cork or the like, shown at 7, this stopper being provided preferably with a reduced portion 8 extending into the end of the coil.
What is claimed is 1. A device of the character described including an elongated coil of heat conducting material, said coil having a closed end portion for engagement with the bottom of a container and an upper end portion for engagement with the neck of the container, and means extending from one end of the coil to be grasped by the user.
2. A device of the character described including an elongated coil of heat conducting material, the convolutions of the coil at one end being reduced to reduce the diam eter of said end, and means extending from the convolution at the other end of the coil adapted to project beyond the open end of the container into which the device is insorted, one end of the coil adapted to engage the bottom of the container and the other end to engage the top thereof.
In testimony that we claim the foregoing as our own, we have hereto aiiixed our signatures in the presence of two witnesses.
