CRAJFE.

application filed March 23, 1922. Serial No. MMM?.

To all whom t may `conce/M1:

lBe it known that l, WALTER WAGNER, a citizen of Poland, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Carafes, of which the following is a specification.

rllhis invention relates to certain new and useful improvements in carafes embodying a multiple wall metallic vessel having heat insulating space between the walls thereof,

said vessel being a wide bodied vessel having a comparatively slender neck.

Carafes of this character have heretofore been constructed of glass or the like with a separate metallic casing, and the manufacture of the same incurred considerable expense and breakage of the same was an undesirable characteristic. lit is the primary object of this invention to form the vessel entirely of metal which may be suitably enameled on the interior and silver or nickelplated on the exterior as well as being composed of a number of separate sectionspermanently, rigidly assembled in such manner as to present a neat and ornamental appearance and so as to provide for the ready and inexpensive manufacture of the same.

A further object of the invention is to provide an improved metal cover for protecting the upper part of the neck of the vessel from rust and the like and also to protect the enamel from being cracked by adding to the ornamental appearance of the invention.

'A still further object of the invention is to provide a multiple wall metallic carafe with a suitable packing between the walls thereof and means for facilitating withdrawal of air from the space between the wall and preventing withdrawal ofthe packl("lhe invention embodies further im rovements in the art to which it relates an more particularly in connection with the application filed by Walter Wagner on March 31, 1921, Serial No. 457,361, allowed November 1, 1921.

A still further object of the invention is to generally implrove devices of this character, whereby t e same may meet with all of the requirements for a successful commercial use.

Other objects will appear as the nature of the invention is better understood, and the same consists of the novel form, combination and arrangement of parts hereinafter 0 more. fully described, shown in the accompanylng drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Flgure 1 is a central vertical sectional view of the preferred embodimentof the invention with parts of the packing omitted for the sake of clearness, a handle being indicated by dotted lines,

Figure 2 is a vertical sectional view partly broken away of a sli htly modified form of one of the inner wa ls of the carafe, and

Fi re 3 is a view similar to Fig. 1 of a modified form of a carafe.

Referring more in detail to the several views, the invention embodies an inner container including a metallic bowl-shaped bottom section 5 and an upper inverted substantially funnel-shaped section 6 with their adjacent margins outwardly flanged and permanently united as at 7 through the medium of spot welding, solder or the like. These two sections of the inner container may be conveniently drawn from a sheet of metal and the tubular portion 8 of the upper section 6 forms a portion ot the neck of the vessel, the remaining portion of which is formed by the inner sleeve 9 of a double walled top member 10 having a sccond sleeve suroundingl the sleeve9 in spaced relation as at 11, and the sleeve 11 being of lesser length than the sleeve 9. The conneet-ing portion between the sleeve 9 and l1 is of annular form so as to provide an imperforate smooth upper edge for the neck of the bottle, and the sleeve 9 is oti'set as at 12 to provide a shoulder or rest for the inturned edge 13 of the upper section 15 of the outer wall of the carafe. As shown in Fig. 2 the inner wall of the receptacle may be formed of a single section of material 5 in lieu of the upper and lower sections 5 and 6 as in Fig. 1.

The outer container of the carafe is formed of a bottom section 111 similar to the bowl-shaped section 5 except that the section 14 is of a larger size so as to leave an annular space between the sections 5 and 14 and the bottom of the section 1d is provide with a reduced annular portion 14 havii a flat bottom surface 14 so that the cara e may rest in a vertical position upon a table or the like. The outer container also embodies an upper section 15 ot substantially the same general form as the section t et the (pending collar or sleeve 26 inner container, butfof uniformly larger size so as to leave a similar annular space between the sections 6 and 15 about the neck portion 8 and the enlarged low'er portion of the inverted funnel-shaped section'6, the

s ections

14 and 15 being joined at their margms by the provision of intertitting beads. as at 16 and by soldering, brazing, orweldlng at this and similar points if found desirable. The beads 16 provide an ornamental joint between the

sections

14 and 15, which .scctions may also be conveniently drawn from sheet metal. The smaller or neck portion 17 of t-he outer and upper section 15 is rovided at a point spaced from its upper e ge with an annular corrugation'or bead 18 for purposes presently to be described.

The adjacent edges of the inner sleeve 9 of the top member 10 and the neck portion 8 of the upper section 6 of the inner container are flanged outwardly as at 19 and are permanently united through the medium of spot welding, soldering or the like. The neck of the bottle is provided with a suitable closure or metal cap 20 which is of double walled construction and suitably constructed .of inner and outer permanently connected and spaced Sections. The lower edge of the cap 1s adapted to rest upon the corrugation or bead 18 of the neck 17 of the section 15 of the outer container.

Slightly spaced from the

sections

14 and 15 of the outer container there is provided an upper and

lower section

21 and 22 of an intermediate container. Similar to the upper sections 6 and 15 of the inner and outer container the upper section I21 of the intermediate receptacle is provided with a reduced neck portion 23, the upper edge of which surrounds the overturned edge 24 of the outer wall 11 of the top member 10 and is firmly secured thereto by welding,` soldering or the like. The adjacent edges ofthe

sections

21 and 22 are secured to each other as at 25 in a manner similar to the securing of the adjacent edges vof the

sections

14 and 15 of the outer receptacle. The bottom of the lower` section 22 is left open and is provided with a dedirectly beneath the bottom of the section 5.

An inverted substantially pan-shaped member 27 is fitted within the bottom opening of the intermediate lower section 22 and within the depending sleeve 26 thereof. and it is secured in position in anysuitable manner as by means of solder or Welding, the top Wall of the member 27 is inwardly depressed to provide a central sleeve portion 28, the bottom of the sleeve portion 28 being closed by a bottom wall 29. A pair of perforated metal disks with a suitable fabric disk is disposed therebetween as generally denoted by the numeral 30 and is firmly held within the sleeve 28 and these disksroverlie' the opening ofa depending sleeve 31 which is provided centrally of the bottom portion 29 which has a suitable check valve 3-2 secured thereon by means of which air may be readily exhausted from the space between the inner and intermediate container of the vessel by proper connection with an air exhausting deviceand to permit the ready attaching of this air exhausting device to the check valve 32, the flat bottom wall 14" of the section 14 has an annular opening 33 therein for receiving a plug 34; The space between the inner and intermediate containers of the vessel is' preferably filled with a suitable packin of heat insulating material denoted Iiy the numeral 36 and the fabric and metallic perforated disks 32 permit the exhaustion of air by preventing withdrawal of the packing. The assembled carafe may be provided with any preferable form of llrandle 35 shown in the views by the dotted lnes. f

In Fig. 3 I have shown a slightly' modilied form of carafe wherein the meeting,r edges of the upper und lower sections 6' ond 5 ofthe inner container' ere tolescoped and firmly united by soldering or the like. This same type of joint is provided between the adjacent edges of the neck 8 of the upper section of the inner container 6 and the lower edge of the inner sleeve 9 of the top member 10. In this form of the invention the sleeve 9 is offset as at 12 to provide a shoulder or rest for one end of a metal cover 13 which is employed for protecting the upper part of the neck from rust and for protecting the enamel of the same from cracking. The upper and

lower sections

21 and 22 in this form are substantially the same as the upper and

lower sections

21 and 22 of the inner intermediate receptacle excepting that the meeting edges 25 thereof are united through the medium of interlocking beaded edges. The opposite end of the upper section 21 is also beaded as at 40 for receiving the beaded lower edge of the protecting cover 13. The bottom of the vessel is formed by a pan shaped bottom forming member 41 which telescopes onto the sleeve 26 of the outer lower section 22 and which lis suitably :fastened upon said sleeve 26 as well as being provided with an annular bead 42 along its upper' edge for ornamental purposes. The pan-shaped member 27 in this instance is inwardly depressed to provide a central sleeve portion 28', and a lower and larger sleeve portion 43 is connected by a horizontal annular portion 44, the bottom of the sleeve portion 28 being closed by a bottom wall 29 arranged in spaced relation to the portion 44.

From the foregoing description it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.
