Be it knownthat .w e, RmNno'rn Burana and ALBERT AsnsNaanNNnn, subjects' of the Kin of Prussia, German Emperor, residing. in.

erl'in,I Germany, have invented certain new and useful Im rovements 1n Field or Hunting Flasks,. or which We have v-ob tained ah patent in Great Britain, numberedV 4,421, A.,D. 1904,' and in France, numbered 340,627 and we do hereby declare thatthe and have been used for other purposes; but

they have not the characteristic shape of our improved bottle andare not provided with a protective jacket.

Another feature of our invention consists in the fact that a layer of heat-insulating material .is arl-an ed in uliar manner between thetwo g ass wa s in order to vent the breaking of the lassb concusslous or the like at that part w 1ere t einner wall of the bottle isl connected with the outer wall-that is to sa at the neck ofv th`e bottle. Specialnove meansfor this purpose will be described hereinafter.

Another'feature of the invention consists in the fact that the tubes for evacuatind the bottle are not arranged at the center o? the bottom, but at the side thereof, so that it can be more .el'ectually protected from in# jury and that the bottle and its jacket can be given a more suitable shape.

The invention is--illustrated in' the andicate similar or 'equivalentparts Figure 1'l is a sideview of one forn of th'e improved bottle; Fig. 2, a. partial vertical section throu -the central axisof another form thereo Fig. 3, a vertical section through 'Fi 1, .and Fig. 4 vasection' on the line A B o Fig. 3.

The ieldor huntin .flask shown in Figs. 1 and 2comprises a su tat-ially cylindrical inner lassreceptacle a, somewhat constricted at t e neck,'and an Outer glass receptacle b, which is also somewhat constricted at the n'eck. The two receptacles a'r'e carefully' fused together at the neck, the entire inner surface having been" coated with a` mercury The vertical .lar projections d in the footof/the outer -re- ;A layer c. .Theair between'the receptacles is then evacuated or exhausted through tubu' ceptacle, which are then sealed. Around the necki of the bottle is arranged an .annular cushion or rotector-e, and the foot or'bottom of the.' ottle .is inclosed in a cup-shaped cushion or rotector f, of suitable elastic inal terial-suc as cotton, wooli asbestos, or the like-or of colophony,.'sl1el ac, sealing-wax; o1 other suitable rigid material. .The bottle lis inclosed in a substantially cylindrical metal case g, to which are soldered four metal'bows la, forlnln eyes. The under art of the .case g is clo by a cup-shaped otA toni L, which is soldered or ix'cd in anyother suitable: 'manner to the case g. Through the 'bows h a strap i can be drawn to serve for carrying ,the bottle, as lusual with field-flasks. bottle a cork or other stopper ccan be inserted, and a removable inverted cup l, can be pushed over the neck. This cup 1n lace in'auy suitable manner.

n the form of construction shown-.in F ig. 3 disks or lates m m', of asbestos board or other suita le` heat-insulatin material, are arranged betweenthe receptac es a and b, so that the latter mutually support each other. Some -of the said lates are horizontally arranged 4and ot ers vertically. lates are sup orted by wire rings n n', `ed to a num er'of vertical wires o, which support the horizontal plates m and m'. The upper ends of lthe wires o can be held are bent overthe curved part of the inner.

receptacle al at .the neck of the bottle and are fixed to a wire ringo (indicatedyby dotted lines in the drawings)v and fastened around the neck ofsaid inner receptacle."

Ve do not restrict our claims to the form -of bottle consisting of two glass receptacles Va 'and b, which is shown in the drawin s, but .also claim all other forms in Vwhich t e bottle could-be used'as a field or hunting;r

tiask'o'r the like. It must-'also be noted thatv the outer receptacle b can be inclosed in a casing of leather or other suitable material-- as, for instance, of. paper,v papier-mch, lartificial leather, woven or knitted fabric, and the like. Finally, wepdesire to point out that the practical value of our invention consistsin the fact that the liquid contained in the improved bottle remainsl for many Into the mouth of the bottle in the mornin vcan keep theliqui hours at; the saine temperature as that which .it hadvwlien poured, into the bottle.-v Thus, for instance, a workingman who fills hisv with hot coffee or milk till the evening,`when it. will still be hot. Itwill'thus easily be understood that the bott-le can with t advantage be used especially in the fi d or when hunting. l Having now particularly described and ascertained the nature of our said invention4 and in what manner the same is to be performed. we declare that what we claim is:

1. A flask, comprising separated receptacles connectedy at their necks and `inclosing a -vacunmchamber between their bodies, lieatinsulating members aiinularly disposed in the chamber, and means embracing the neckl of the inner receptacle and holdin the said members in position, substantial y as described.

2. A flask, comprising separated receptacles connected at their. necks and inclosing a vacuum-chamber between their bodies, horizontal and vertical insulating members aniiularly disposed in the chamber, and a wire structure suspended from the neck of the iimer receptacle and holding the said meinbers in position, substantially as described.'

A flask, comprising an inner receptacle,

and an outer receptacle connected thereto atv the .neck and presenting in conjunction with the first a vacuum-chamber and having two sealing-tents one at each side' of the bottom,

heat-insulating members aiinularly disposed in the chamber, and means for holding the said members in position, substantially as described.

4. A flask, comprising an inner receptacle, and an outer receptacle connected thereto at the neck and presenting in conjunction with the first a vacuum-chamber and having twoA sealing teatsone at each side o f the bottom, lient-insulating members annularly disposed.

in the chamber, means for holding the said members iiiposition. a- )acket inclosing the outer receptacle, and a filling interposed between the outer receptacle and its jacket. at the neck and foot. substantially as described.

5. In combination with `a vacuum glass double walled vessel, a plurality of supports inserted between tlie' \\'alls of said vessels. andw means for holding said supports againstV displacement. y

6. In combination with a vacuum glass double walled vessel, a plurality of supports Aof elastic material interposed between the walls of said vessels, and means for holding said supports against displacement.

7. In combination with a vacuuni glass double walled vessel, a plurality of supports of heat insulating material interposed .between the walls of -said vessels, and meansfor holding said supports against displacement.

8. In combination with avacuum glass double -walled vessel having a constricted neck and a cylindrical portion, a plurality fof supoports interposed between the walls of,

said neck.

9. In combination with a vacuum glass d v portion at a distance from said double walled vessel, a plurality of supports interposed between the walls of said vessel and mutually connected together.

double walled vessel, a plurality of supports interposed between the walls of said vessel, and a ring connecting said supports.

11. In combination with a vacuum glass double walled vessel, a casing of metal covering the said vessel and having a. flange ex- 1U. In combination Vwith a vacuum glass2 vtending over the circumferential edge of the mouth thereof.

12. In combination with a vacuum glass double walled vessel h avin a` constricted neck, a casing of less frangib e material covering the outer surface of said vessel and having a constricted neck completely inclosing said vessel neck, and an annular band of elastic material 'disposed inand filling the space between said necks.v

13. In combination with a vacuum glass double walled vessel havin a constricted neck, a casing of less frangib e material covering the outer surface of said vessel, and

means wholly inclosing the neck of said vessel kfor supporting the saine within said cas,

14. In coinbination with a vacuum lass double walled vessel havin a coiistricted neck, a casing of less frangib e material covering the outer surface of said vessel, means wholly inclosing the neck of said vessel for support-ing the saine within said casing, and means interposed between the walls of said vessel for preventing lateral vibrations nf the inner wall;

15. In combination with a vacuum glass double walled vessel having a sealing teat, a casing coverin the outer surface of said vessel, and a y of elastic material interposed between the said vessel and said casing and embedding said'sealing teat.

In testimony whereof we allix our signatures in presence of two witnesses.
