Be it blown that VICTOR S Jonnson, a citizen of the United States, residin at Chicago, in the county of Cook and of lllllIlOlS, has invented certain newand useful Improvements in Heat-Insulated Vessels, of which the following is a speci, fication.

The invention relates to heat-insulated vessels which include an outer jacket and an inner frangible containen and said invention consists broadly of novel means whereby the container, if broken, may be readily removed and another container substituted therefor. Uther objects, also, are attained by the new construction as will hereinafter more fully appear.

The single figure of the drawing represents a vertical sectional view of parts of? the vemel, parts being shown in elevation.

The outer jacket 1,-is composed of a lower section 2, and an upper section 3 which, at its lower edge, telescopes with the upper edge of the lower section 2 and is screwed to said lower section by screws 4i entering an anchoring nut '5.

The upper section 3 terminates below the top of the "vessel at a point where it coincideswith an inner multi-part jacket 6, hav ing a shoulder 7 on which an inturned lip 8 of the outer jacket it rests, the inner jacket 6 being continued upward and provided with an inturned flange 9 which extends over and protects the edge of the frangible container 10. A mass oi heat-treated lac disposed between the necks of the inner jacket 6 and the container 10,'permanently unites said necks.

The space between the inner jacket 6 and the container 10, is filled with a suitable comminuted heat insulation 11, and the outer jacket 1 and the inner jacket 6 are separated to provide a non 'heat conducting air space 12 which supplements the action of the heat insulation 11.

The neck 13 of the inner jacket 6 is screwthreaded to receive a screw-threaded drink in cup 1dof ordinary character.

he bail 15 is connected to the vessel by ears 16 secured to the upper section 3 of the outer j acket,the object of this arrangement being to avoid the removal of the bail and its ears when the inner jacket and a fractured frangible container are removed.

When a new container is to be substituted tate 19th. fierial Kilo.

per section is set aside. The old filler, in-

eluding its container .is then taken out and a new filler including an inner acket 6, a frail ible container 10, and insulating materia 11, is inserted in its place. The section 3 is then replaced and made fast by the screws. d.

The-inner jacket 8 has a joint l8'uniting two of its

sections

19, 20, and the section 20'has a bottom-2i provided with cavities 2% fitting knobs %3 in the bottom 24 of the section 2 oi the outer jacket, thesedevices insuring a minimum area of contact between the two jackets, and the filler as a whole, being prevented from turning in the outer jacket by said cavities 22 and knobs 23.

The device provided with a heat-insulated stopper which is not herein claimed.

Having thus described my invention, ll claim:

l. A heat-insulated vessel including a removable outer jacket and a unitary filler, said filler including a frangible container, a heat-insulator surrounding said container, and a jacket enveloping said heat-insulator, said filler jacket being spaced from said outer jacket.

2. A heat-insulated vessel including an outer jacket and a removable unitary filler, said tiller including trangiblecontainer, a

tilt

heat-insulator surrounding said container,

and a jacket enveloping said heatinsulator,

said filler jacket being spaced from-said outer jacket. 4

3. A heat insulated vessel -including an outer jacket and a unitary filler disposed within said outer jacket and interlocked with said outer jacket at its base to prevent said filler from rotating relatively to said jacket. i

ii. A heat-insulated vessel including an outer jacket and a removable innerjacket, said outer jacket having a knob in its base portion and said inner jacket having a cavity into which said lmob extends.

5. A heat-insulated vessel including a multi-part' outer jacket and a unitaryremovable filler provided with a frangible container and a neck portion constitutin a separable continuation of said outer jac st and secured to the wall of said container.

6. A heat-insulated vessel including an ice outer jacket, a removable inner jacket ex-' tending above the outer jacket, and a frangible container heat-insulated from said inner jacket and held at its upper end by the upperend of said inner jacket.

7; A heat-insulated vessel of the nonvacuum type including a multi-part outer jacket and a bail for said outer jacket, and including also a. removable composite filler extending above said outer jacket and provided with a heat-insulated, frangible container.

8. A heat-insulated vessel including, a unitary filler comprising an inner frangible container, heat-insulating material surrounding said container, and a jacket surrounding said heat-insulating material, and including also an outer jacket terminating at and extending over a shoulder of the jacket of said filler.

9. A heat-insulated vessel including a permanent portion, and a bail fixed to said permanent portion, and including also a eat-insulated removable frangible container, extending above said permanentportion.

10. A heat-insulated vessel including a multiart outer jacket and a unitary removabe filler, said filler being held between an inturned portion of said outer jacket and the bottom of said jacket when these sections of said outer jacket are united. a

11. A heat-insulated vessel including a multi-part outer jacket and aunitary removable filler, said filler being held between an inturned portion of said outer jacket and the bottom of said jacket when these sections of said outer jacket are united, and

interlocked with the lower section of said outer jacket to prevent rotation thereof in said outer jacket.

12. A heat-insulated receptacle of the non-vacuum type: including a multi-part outer jacket and a unitary removable filler, said filler'having an inner frangible container and a jacket of non-frangible material spaced away from said container around its body portion, the space between said container, and jacket being filled with heat and shock insulating material, and said filler being spaced away from the outer jacket.

13. As an article of manufacture, a unitar-y'heat-insulated filler of the non-vacuum type comprising a strong frangible con t'ainer, andan outer jacket spaced from the container and having near its upper end a shoulder and at its lower end a depression, the space between said container and said jacket beingfilled with heat-insulating and shock-absorbing material. I

14:. A heat-insulated vessel of the nonvacuum type, having an outer multi-part protective jacket and a unitary removable filler, said filler including a frangible container and a jacket of non-frangible material spaced from said container, the space between said container and said jacket be-- ing filled with comminuted heat-insulatingmaterial, and said filler jacket having a depression near its top coinciding with the outer protective jacket andan interlock at its bottom ot prevent said filler from rotating within said protective jacket.

In testimony whereof I aflix my signature.
