- off connection consists of a first fitting which is preferably cup-shaped, connected with the outlet of the frangible container, from which fitting a flexible tubular member extends laterally in the space between the frangible container and its protective shell, the other end of said tubular member being connected at a. location substantially removed laterally from said outlet, with a second fitting extending through the protective shell to receive the draw-off device or faucet employed.
- Said tubular member is made preferably of thin-walled soft metal tubing, for example, copper or brass, of such length that it readily yields to shocks on the faucet and the fitting connected. therewith, as a result of which any resultant minute shocks communicated to the outlet of the frangible container, are so small as to be much less than shocks that are dangerous thereto.

17 Claims.
My invention pertains to insulated containers of the type which may be conveniently carried by hand from place to place, in which an inner vessel or container for liquids, made of frangible material such as stoneware, glass, or other vitreous material, is mounted in and spaced from an outer protective shell, the space between said container and said shell being usually filled with resilient material affording thermal insulation and also shock insulation tothe container, for
example comminuted cork.
A well known example of such containers is the so called picnic jug intended to keep any desired liquid contents either hot or cold as the case may be, for a considerable time, and of a size and construction to be readily carried by hand, although I do not limit myself to that particular type of such containers in carrying out my invention.
With containers of the class referred to, it is desirable in some cases to provide the container with a draw-off faucet communicating with the bottom portion of the inner frangible vessel or container, and located outside of the protective shell of the container. In such cases, as far as I am aware, it has heretofore been the practice to connect one end of a substantial tubular connection to an outlet in the side near the bottom portion of said frangible container, and to extend said tubular connection directly outward- 1y through the protective shell to receive and support at its outer end, the draw-off device or faucet employed, said tubular connection in some cases being secured to said protective shell. With draw-off connections of the kind described, experience has shown that shocks on the faucet resulting from impacts of any kind, are transmitted through the draw-off connection to the frangible container with so little decrease in 0 force as to be dangerous, such frangible containers frequently having been broken in this way by impacts on the faucets that would seem to be inconsequential. Even where the draw-off connections have been secured to the protective because of it being practically impossible to make the protective shells sufficiently rigid to prevent communicating dangerous shocks to the frangible containers in the manner described. to .By my invention, I eliminate the communicating of dangerous shocks to the frangible container through the draw-off connections, by differently constructing the tubular connection extending from the frangible container to the 55. draw-off device or faucet. My improved draw- 5 shells, the same result has frequently occurred,
off connection consists of a first fitting which is preferably cup-shaped, connected with the outlet of the frangible container, from which fitting a flexible tubular member extends laterally in the space between the frangible container and its protective shell, the other end of said tubular member being connected at a. location substantially removed laterally from said outlet, with a second fitting extending through the protective shell to receive the draw-off device or faucet employed. Said tubular member is made preferably of thin-walled soft metal tubing, for example, copper or brass, of such length that it readily yields to shocks on the faucet and the fitting connected. therewith, as a result of which any resultant minute shocks communicated to the outlet of the frangible container, are so small as to be much less than shocks that are dangerous thereto. To conserve space, I preferably extend said tubular member angularly around the 20 frangible container, thereby displacing said outlet and said faucet from each other by a substantial amount angularly of the container, but I do not limit myself to this particular arrangement. Where the containers are intended for liquids for human consumption, I preferably provide my connection and particularly the tubular member thereof, with a lining of tin or equivalent material as far as protecting the liquids from contamination is concerned. 30
My invention will be best understood by reference to the accompanying drawings illustrating a preferred embodiment thereof, in which-- Fig. 1 shows in front elevation and partially in vertical, sectional view, a jug container in 3 accordance with my invention;
Fig. 2 shows in vertical, central, sectional View and to an enlarged scale, a part of the container shown in Fig. 1;
Fig. 3 is a horizontal, sectional view of the structure shown in Fig. 2, taken along the line 3-3;
Fig. 4 shows in a view similar to Fig. 3, a modified construction of tubular connector;
Fig. 5 shows the tubular connector illustrated in Figs. 2 and 3, in plan View;
Fig. 6 is a left hand end view of the connector shown in Fig. 5, taken along the line 6-5;
Fig. 7 is a right hand end view of the connector shown in Fig. 5;
Figs. 8, 9 and 10 show further modified forms of connecting tubes, in view similar to Fig. 3.
Similar numerals refer to similar parts throughout the several views.
In Fig. 1, I illustrate in front elevation, a jug container in accordance with my invention, the lower portion of the container structure thereof, as more clearly shown in Fig. 2, having an inner vessel or container Ill, for example, of stoneware, glass or other vitreous material, surrounded by and spaced from a protective shell or jacket II, for example, of metal such as sheet brass or steel. The space between the parts Ill and II is shown as filled with resilient insulating material I2, for example, comminuted cork, to provide heat insulation and also shock insulation for the container I I].
The bottom portion of the container ID, as more clearly shown in Fig. 2, is provided with an outwardly extending tubular outlet Illa integral with the container Ill, which outlet increases in size or flares outwardly. A metal sleeve I3 is secured to the outlet Illa as follows:
The body portion of the sleeve I3 is of somewhat larger internal diameter than the outer diameter of the outer end of the outlet Ifla, the inner end of said sleeve being inturned at I30, so that it will just clear the outer end of said outlet in assembling said sleeve, the outer end of said sleeve having an inturned flange I3b resting against and fitting the outer end surface of the outlet Illa when the sleeve I3 is assembled thereon, for which relationof the parts, there is a clearance space between theinturned end I3a of the sleeve and the outer surface of the container II], which insures snug engagement between the sleeve flange I31) and the outer end of the outletIBa. In assembling the sleeve I3, cement I 30, for example, water insoluble vitreous cement, is used to fill the space between the sleeve and the outlet Illa, and with the cement in place, the sleeve is pressed towardsthe container Ill, to press the flange l3b snugly against the outer end of the outlet Illa. When the cement has hardened, the sleeve I3 is interlocked in place on the outlet Illa by the relation to the hardened cement I30, of the inturned end I3a, of the flange I31), and of the outward flare of the outlet Ilia.
As shown in Figs. 2 and 3, the sleeve I3 has secured to it in any convenient manner, for example, by soldering, the flange I ia of a flanged cup I4 of metal, which constitutes a first end fittingof my improved connector. The cup I4 has secured thereto, for example, by soldering, brazing or welding, one end of a connecting tube I5 of metal, the other end of which is similarly connected to a second and hollow fitting I6 of metal, having a hollow threaded end portion Ilia extending through the shell II, and secured to said shell by a'lock nut ll outside of said shell.
A washer I8 of suitable material, is disposed between the fitting I6 and the inner surface of the shell II. The fitting end portion I60. extends through the nut II. and engages a draw-,oif faucet I9 to support the latter outside of the shell II. The tube I5 opens into the cup I4 and into the fitting I6, thus establishing open communication between the container outlet Illa and the faucet I9. To tightly hold the fitting I6 against movement relatively to the shell II when mounting the faucet I9 on, or removing the same from said fitting when desired, I prefer to rigidly secure said fitting l6 and the locknut II to the shell II by soldering, brazing or other known means, thereby protecting the tube I5 from damage that might result from turning movement of said fitting. This permits the use of a very thin walled tube I 5, which not only eliminates the communication of appreciable shock to'the container outlet Illa by impacts on the faucet I9, but also macontents cold.
The construction of the tubular connector is more clearly'shown in Figs. 5, 6, and '7. In Figs. 5 and 'I it will be noted that the fitting I6 is provided with a shoulder I61) adjacent its threaded extension llia, to engage the washer I8 when the parts are assembled as shown in Figs. 2 and 3. The tube I5 is preferably of soft metal, for example, copper or brass, and very thin walled, as a'result of which any shocks exerted upon the faucet I9, readily bend the tube I5 and appreciable resultant shocks are not communicated to the container outlet Illa, the length of the tube I5 being sufficient to accomplish this result. To make the connector structure sanitary and wholesome for domestic purposes,I line said structure and particularly-the tube I5 with tin, or similar material inert to liquids for'human consumption.
In Fig. 4 I illustrate a connector structure similar to that above described, the difference being that the 'cup fitting I l and the fitting I6 are more widely separated than shown in Fig. 3, the connecting tube I5a being correspondingly longer than the tube I 5 shown in Fig. 3. This gives greater flexibility to the tube a and correspondingly greater shock protection to the frangible container outlet Illa. It will also be noted that the curved condition of the tube I5a shown in Fig. '4 permits said tube to bend more readily under impacts on the faucet I9 than where the connecting tube is straighter as shown in Fig. 3.
In Fig. 8, I show the container outlet Illa connected with a fitting mounted on the shell II and supporting a faucet I9 as above described, by a thin-walled-metal tube 2| integral at its inner end with an annular diaphragm 2Ia resting at its outer portion against the outer end of the outlet Illa, said diaphragm'at its outeredge being integral with a sleeve portion 2Ib surrounding the outlet Illa and inturnedat its inner end at 2Ic, said sleeve being secured to said outlet by suitable cement as above described. The outlet Illa is of substantially larger diameter than the tube 2|, to constitute the diaphragm '2lal a readily yielding member incapable of communicating dangerous shocks-from the fitting 20 to the outlet Illa.
'In Fig.9, I showthe container outlet Illa connected with the fitting'Zll mounted on the shell I I and supporting a faucet I9 as above described, by a thin-walled-metal tube 22 having flexible circumferential folds 22w throughout its length, which tube 22 is secured to the sleeve I3 mounted on the outlet Illa as above described. The size and number of the folds 22a are such that the tube 22 constitutes a readily yielding member incapable of communicating dangerous shocks from the fitting'Zll to the outlet Illa.
In'Fig. 10, I show thecontainer outlet Illa connected with the fitting I6, by a thin-walledmetal tube 23 having a U-shaped conformation and secured at its inner end to the cup-shaped member I4 in the manner above described for the tube I5. The length of the tube '23 is such that for the thickness of wall of the tube and'the kind of metal that may be selected in making the tube,
said tube constitutes a readily yielding member incapable of communicating dangerous shocks from the fitting Hi to the outlet lila.
While I have shown my invention in the particular embodiment above described, it will be understood that I do not limit myself thereto, as I may employ equivalents thereof known to the art at the time of the filing of this application, without departing from the scope of the appended claims.
