HEAT-INSULATING VESSEL.

I Specification of Letters Patent.

Patented Aug. 29, 1911.

Application filed August 20, 1908. Serial No. 449,528.

To all whom it may concern: 7

Be it known that I, CONRAD HUBERT, a citizen of the United States, residing at the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Heat Insulating Vessels, of which the following is a specification, reference being had therein to the accompanying drawings, forming part thereof.

My invention relates to heat insulating vessels having double walls inclosing between them a vacuum space.

Vessels of this class have heretofore been devised mainly for the purpose of containing liquids and have been impractical for use with solids, such as ice cream, for example.

One object of my invention is to provide a vessel which will be serviceable for solids as well as liquids.

Other objects are convenience, reliability, economy, and facility of manufacture.

Other objects and advantages of my invention will appear from the following description.

I shall now describe my invention with reference to the accompanying drawings and shall thereafter point out my invention in claims.

Figure 1 is an elevation of my improved vessel showing the protective jacket, the interposed cushion, the gasket and the 'connecting band partially in section. Fig. 2 is an elevation showing the parts disassembled and one of the containing portions in vertical central section.

The two cup-shaped receptacle members 1 and 2 are in every respect substantial duplicates of one another, and, hence, a description of one will apply to either and I shall therefore confine myself to a description of the member 1. This has an inner and outer wall 3 and 4, respectively, preferably of glass or other vitreous material, joined together at the mouth and containing between them a vacuum space 5, from which the air is exhausted at some convenient point, as through the. tip 6, which is then fused shut. To increase the heat insulating efliciency of the vacuum, the inner surfaces of the walls may be silvered as is commonlydone. This receptacle member is provided with embracing means such as the usual outer casing or protective jacket 7, which is clenched or bent over the mouth of the vitreous reeep- -Paris.

conductive material is placed within the jacketing member so that the bottom of the vitreous member rests upon it and is supported thereby. To protect the tip 6 from injury, it is inserted within the ring 10 and may be provided further with a protective cap 11 of the same material as the ring 10.

To combine the two receptacle members 1 and 2 into one vessel, they are placed with their mouths together and thus secured, as shown in Fig. 1. For this purpose the con necting band or collar 12 is used. This is provided with screw-threads, which engage corresponding screw-threaded portions of the casings near their mouths and thus hold the two members together. An insulated joint is formed by interposing an annular gasket 13 of rubber or other suitable heatinsulating material. This is shown in the drawings as consisting of two rings with one placed upon the other, though obviously one whose thickness equals that of the two would serve the same purpose.

In the embodiment of my invention shown in the drawings and above described, I employ two substantially similar receptaole members, though obviously these could differ in size and could be made in any shape to suit the convenience; and it is obvious that other methods of joining the two members could be employed and various other modifications could be made in the construction shown and above particularly described within the principle and scope of my invention. A

, I claim:

-1. A heat insulating vessel comprising two' members, each a containing member'having double walls joined at the mouth of the member, and separable embracing means for the heat insulating containing-members to hold the two containing-members together to form a single closed heat-insulating vessel.

2. A heat insulating vessel comprising two vacuum insulated containing-members, protective jackets for the containing-members, and means for joining the protective jackets together at the mouths of the containing-members to form a single heat insulating vessel. t

3. A heat insulating vessel comprising two vacuum insulated containing-members, protective jackets for thecontaining-inembers, and a connecting collar for joining the protective jackets together at the mouths of the containing-members to form a single heat insulating vessel.

4. A heat insulating vessel comprising two vacuum insulated containing-'members, protective jackets for the containing-members,

- and means on theprotective jackets for j oin ing the two containing-members together at their. mouths to form a single heat insulating vessel.

5. Aheat insulating vessel comprising two vacuum insulated containing-members, protect-ive jackets for the containing-members, and a connecting collar for joining the pro tective jackets together at the mouths of the containing-members. to form a single heat insulating vessel.

6. In combination, two substantially similar heat insulating containing-members, protective jackets for the containing members having screw-threaded portions near their mouths, a connecting collar provided with screw-threads and adapted to join the two containingmembers together at theilr mouths to form a single heat insulating vessel, and a gasket interposedat the juncture of the two members to form an insulated joint.

In testimony whereof I affix my signature in presence of two witnesses;

' CONRAD HUBERT.
