APPLIUATION FILED NOV. 4, 19081 Suva/mrow tending centrally and vertically throughthe LEONARD alsmaar., or iainwauznn, wisconsin.



Specification of Letterslatent. I Patented May 10, 191i). I

Application filed November 4, 1908. Serial No.` 461,073.

To all whom it muy concern:

Be it known that I, LEONARD R. Sfrnnn,'a` citizen ofthe United States,resi`ding at. Milwaukee, in thecounty of Milwaukeeand State 0f Wisconsin, have invented new and useful Improvements in Bottles, of which the following 'is a specificati0n.

My v.invention relates to improvements in bottles, and its primary object is the. provin sion of a device of this character in which liquids 'may be kept at a predetermined tein- A perature without the employment of a rebottle, and Fig. 2 is view in side' elevation of the bottle, the upper and lower section of the bottle being shown separated.

Referring to the drawing' by reference 4 v charaeteisil` designates the casing of my improved bottle, the'casing being preferably constructed yof glass and in two sections. These'ctions are cylindrical, and the lower section 1L is provided withl an integrally formed bottom wall 2.` The upperend of this section is increased inthickness to pro vide a bead 3 whichhas itsupper surface screw-threaded and Vwhich-is provided in Vits under surface with a groove 4. The upper Iand lowerends-ofthe upper section 5 are fully open7`and the lower end of the section `1s alsoincre'ased in'thickness to provide, a

bead '6 `which liasdts outer surface screw.

threaded and which has 'its upper surface .provided with a groove? A washer 8 is interposed between thebeads and f6 to pro- 'vide an air tight' connection between the sec-4 tions. The sections are secured together by means ofy a coupling sleeve' 9' which is threaded for engagement with the threads of the beads 3 and 6. Theupper edge of the coupling sleeve 9 is provided with an inwardly and downwardlyv bent iiange 10 which lits in kthe groove 7 of the bead 6.

'into the groove l of the bead 3. flange 10 Yof the eouplingsleeve 9 is located when the sleeve is adjusted to properly con-y nect the sections 1 and 5, are bent upwardly As the in the groove P@and as the serrations 11 thereof are located in the groove 4, it 1s 11n-f possible for the sections to become accidentally separated. The upper portion of the section o is slightly reduced, an inwardly disposed annular shoulder 12 being located 'at the upper end of the section. The upper end of this section is threaded to receive the threaded flange 13 of a cap 14. The cap also includes a hollow cylindrical upwardly eX- y tending projection 15 whichis smaller in di ameter than the iian'ge-l and which is connected to the upper edge of said flange by means of a horizontally disposed flange 16, the flange 16 resting upon the upper edge of --the section 5 when the cap is in applied p osition.. A cylindricalv receptacle B which 1s preferably made of glass is mounted in the' casing A, the diameter of which is such that Vits upper endsnugly contacts with the innerwall of the flange 12, said flange 'equally spacing the sidewall of the `receptacle from the side wall of the casing. The upper end of the receptacle B is fully open while its lower end is closed by an integrally formed wall 17. f

The space between the side walls of the casing A andreceptacle B -forms a dead air lspace which prevents liquid lin the bottle from'l absorbing the hea-t of the atmosphere and which prevents vthe heat of the liquid from radiating, thereby enabling the liquid to' be kept at a predetermined temperature in the bottle. The hollow portion 15 of the cap 111 also forms fa dead air space between the upper .surface of the contents of the bottleand the top of the cap which resists the absorption of heat by the liquid in the bottle and-theradiation of heat from the liquid. As a further means of preventing the absorption of heat by the liquid inthe bottle and the radiation of heat from the liquid, the inner surface of the casing A is provided with a lining 1S and the outer surface of the receptacle B with a lining 19. The lower end of the side wall of the lining 18 is odset inwardly to provide an annular flangey 2O which is received by of the bottom wall 22 of the lining, the botlill the annular flange 21 receives the lower end of the side wall of the lining, the bottom `Wall being secured to the sidewall by means of solder. The upper ends-of the side walls of the linings 18 and 19 are'oset, inwardly to provide upstandingV annular flanges which are received by an annular memberb, said member being secured to the anges by means of solder. The

" linings are constructedv of 're-tinn'ed sheet metal which during the process of retinning is dipped inra mercurial solution; The re tinning and m'ercurial solutions combine and form mirrored surfaces which add .materially to the appearance of the bottle.

" :It should be apparent from the above de- 'scriptiom talren in connection with the ac# companying drawing, that I provide a bottle which is admirably adapted for the purpose for which it is intended, one which may be readily and quickly cleaned, and one which may be manufactured and sold at a comparatively low cost.

' v lChanges in the form, proportions and mi- '..lior details of construction may be made the scope of the claims lwithout de- `partingfrom the spirit orsacriicing` any of l tlief advantages of the invention.

"Having thus described the invention, what is claimed as. new '1s:-

1. lA bottle comprising asectional casing, I

each section being bead, each bead groove, a coupling sleeve mounted on the bead, portions of the coupling sleeve being bent into grooves, a receptacle arranged within and spaced from the casing, and a closurefor the bottle.

pjrovided lwith a threaded A'bottle comprising a casing, Va mirrored lining arranged within the casing, a receptacle arranged within and spaced' from the casing, a mirrored lining secured to the outside of the receptacle, and a closure for the bottle. 3. A bottle comprising a casing having an inwardly disposed flange, a receptaclel arranged within the casing, said iange spacing the receptacle from the casing, and a closure for the bottle. l

4. A bottle comprising a sectional casing, means securing-the sections of the casing together, a lining on the inside of the casing,

a receptacle arranged within and spaced t from the casing, a lining on the outside of the receptacle, anda cap threadedly mounted on the casing, said cap being provided with a hollow portion forming a dead air space above the contents of the bottle.

In testimony whereof I alix myl signature in presence of two witnesses.
