RAYMOND B. PRINDLE, OF SOHENECTADY NEW' "YORK7 ASSEGNOR TO GENERAL ELEC- TRIO COMPANY, A CORPORATION OF'NEW YORK.
'HETJNSULATED RECETAGLE.
Application filed August 30, 1924. Serial No. 735,132.
The present invention relates to the construction oi receptacles of the Dewar flask type which are constructed to afford heat insulation between its contents and the eX- terior by an evacuated space.
Receptacles of this type when consisting entirely of glass are fragile and especially susceptible to damage at the neck where the inner and outer walls are joined to each other. On the other hand vacuum-insulated receptacles made entirely of metal are subject to greater heat losses by conduction from the inner to the outer wall.
In accordance with my invention Il have provided a heat-insulated container in which the inner wall consists of glass which is joined to the outer wall, which may consist "either of metal or oit glass, by a ring o1" metal which is so thin as to be yielding to shocks, and which makes a vacuum-tight seal with the inner and outer walls.
The accompanying drawing shows in Fie. 1 a vertical section of a metal and glass device embodying my invention; FiO'. 2 illust-rates in section part oiE a device having inner and outer walls of glass and Fig. 3 is a. ragmental view of a modification.
rlhe device shown in the drawing comprises a somewhat cylindrical receptacle 1 of glass, which is adapted to contain a liquid. Surrounding this receptacle Vis a metal jacket 2. The receptacle l may consist of ordinary lead glass. rlhe jacket 2 may consist of steel or other suitable metal. The lip 3 of the receptacle 1 and the inwardly extending rini l ot the jacket 2 are joined by a ring-shaped member 5, which preferably is somewhat tapered or cone shaped in form. This member or sleeve 5 consists of a metal having about the same coefficient of'expansion as the glass constituting the receptacle 1. For example, when the receptacle 1 consists of lead glass the sleeve 5 may be composed of an alloy known as invar, consisting of nickel and iron (65 parts iron, 3 5 parts nickel) and preierably is copper coated at the region sealed to the glass. An alloy of 80 parts iro-n and 20 parts chromium and containing 0.1% carbon also may be used. When glass other than lead glass is used the composition ot the sealing ring 5 should be chosen accordingly to have substantially the saine coefficient of expansion as the glass. In the case of pyreX glass, a thin copper sleeve may be used. Platinum although usable in case 'oi lead glass is not to be recommended because oi its cost. v
The sleeve 5 preferably should be^suiti- At the end opposite the seal between the inner container and outer wall a cushioning means may be provided such as the pads 0. 7 which may consist ci? teit, wool., or other resilient material, whereby the etlect oiE shocks may be absorbed so as to prevent breaking of the seal. The inner receptacle 1 is provided as usual with a. stopper "t" which may consist of ground glass, of cork, or of other suitable composition. "lhe upper end of the jacketing member 2 is preterably provided with a cover 9 which may make a rictional tit as indicated.
The space rbet-Ween the inner and outer walls ot the eceptacle either is evacuated and then sealed or as shown in Fig. 2 is evacuated and filled before sealing with a finely divided material 10, preferably a material, such Aas finely divided carbon, which has been preheated and hence is c apable of absorbing gas.
The seal at the connection to the vacuum system may be made in any lniown way. For example, the plug 11 may be sealed into the jacket 2 by the iusion of solder or other low melting metal by local heating while the receptacle is supported in an evacuated. spiace, such as a vacuum furnace in which the parts are bakedout and evacuated. The plug 11 may be protected by extending the wall of the outer container as indicated at 12 and lilling the space within this eXtension with a composition material 13 such as ground cork compacted with a suitable binder.
My invention also may be embodied in a device in which both the inner and outer wall of the heat-insulated receptacle consist of glass. Fig. 3 is a ragmental sectional view oi such a device showing part oi the neck of a glass container in which the inner llt) Wall 14C and the outer Wall 15 both consist of glass and are joined by a double Walled ring 1G consisting of an alloy of iron with nichel or chromium, such as above described, having substantiaily the same thermal coei' cient et' expansion as the glass. rhel edges of the open end et this double Walled cyl inder arc. joined by fusion to the gaes walls 14- and l5 as indicated and the closed end ot the cylinder is preferably joined by soldering or bray-:ing to a ring i? ci steel, or other suitable metal, which i-n turn is joined by brazing` or otherwise to the flange 18 ot a n'ietalhousingv 12S). A cap 2O may be iittcfl frictionally upon the housing;` 19 as indicated. The space between the; two .glass Valls 11ia-nd l5 may be evacuated through a glass tube and sealed ofi?- by fusion. The exhaust tip has not been shown in t: figure, as this method of exhausting andfsealfj" y iter suppontmg saidY receptaclev Wholly Within ing' are Well understood;
lVhat I claim asneW` and' desire to secure by Letters Patent of the Unit-ed States is zl. A heat-insulated` ContainerV comprising a sea-led double-Walled receptacle, the inner Wall at least of which consists of glass and a ring1 of metal, the metal being sufficiently thin to be yieldable to shocks.
2. A heat-insulated container for liquids,
or the like, having` a plurality ofA `Walls spaced apart, one of which consists of glass and a ring of thin, resilient metal, said ring making a vacuum-tight jointvbetween said Walls, and having substantially the same coeficient of expansion 4asthe glass'wall the space between said Wallsbeing evacuated.
3. A heat-insulated container.comprising an outer casing of metal, any inner vitreous receptacle spaced from said outeracasing,
and a resilient sleeve of metal Wholly Within and spaced from said casing, said sleeve having substantially the same thermal coeilicient of expansion as said vitreous receptacle joined by fusion to said casing' and to the upper edge of the receptacle, the space between said casing and receptacle being evacuated.
4. A lea `-insulated container comprising an outer casing of metal, an inner receptacle oli glass spaced' away from said outer casingand Wholly Within said casing, and a tapered sleeve of metal sealed into said glass Wall and Welded? to the metal walh said sleeve having` a thickness of a few mils te beingo't'increasingg thickness in the direct ion oil the weld to the metal wall.
5. lli-combination, any outer metallic casand aninner vitreous receptacle, means :r'l'einiiw saidl seal into the class wall and sing', said meansV including a yieldable "metallic ring extending downwardly into `said `casing` and permanently connected to .the upper` end of said casing andA to the upper edge of saidw receptacle, the. space between' said casing and receptacle being evacuated.
'6. In, combinatiom, ar metallic casing, an 'inwardly' and downwardly extending` rim adjacent one end et the casing, a vitreous` .receptacle supported Wholly Within the cas- -ing', the supporting'means including' a yielding` metallic ring; permanentlv united with the said rim and the upper edge of said receptacle.
n Witnesswvhereof, I have hereunto set myhand this 28th day of'Augrust, 1924.
