Letters Patent No. 94,907, dated September 14, 1869.

The Schedule referred to in these Letters Patent and making part df the same.

To all whom tt may concern:

VBe it known that we, JAMES O. MORSE, of Englewood, in'the county 'of Bergen, and State of New Jersey, and GARDNER'D. Hrscox, of Brooklyn, inl l the county ot'fvKings, and State` ot" New York, have invented a newand useful Improvement in Kettles Afor Boiling by Steam; and 'we do hereby declarethat the following is a full, clear, and exaotvdescription thereof, and of its mode or manner of operation, reference being had to the accompanying drawings, and to the letters of reference marked thereon, and makl ing a part of this specification.

Oui-,invention consists essentially in'4 the combination of a body, made of any suitable sheet-metal, with a hollow castl bottom, around the upper portion of which it is closely lit-ted, the hollowr bottom being iitted to receive and contain steamand' having or being capable of having its upper surface tinned, or other wise protected against corrosion, by any chemical ,action of the contents of the vessel.

In the figure, which is`a vertical section, taken through the centre ofthe vessel- A represents the body or containing portion, and

B, the hollow'cast bottom.

rlhe former maybe madel of copper, tin, tinned sheet-iron, or othersheet or thin metal.'

The upper edge ot' the bottom Bis dressed oit' in cylindrical, or any other convenient.' form. Its upper horizontal surface is then coated with tin, by any suit-able process, Orwith any other covering or prep-.1

`ration, which will 'protect the iron against the cheniical action of the contents of the vessel, without interfering` with the transmission of heat. i

The lower port-ion `of the body A is accurately fitted tothe dressed portion of the edge of the hollow bottom B, so as to shut down around it, resting on `the projecting ledge or flange d.

The jointbetween them is made permanently tight by solderingor other appropriate ineans. i Steam is taken inzat one of the openings a, while the drip from its condensation .escapes'tln'ough the other, suitable connections being applied to both.

p Anynuniber ot' stays, b, connecting the upper and lower* surfaces, may be introduced, according to the diameter of B, and the pressure of steamv under which `it is to be used.

The central stay, c, if enlarged artid made hollow,

may have a pipe and faucet applied to it, and be used for drawing olf the contents of the'vessel.

Instead of the sheet-metal composing the body A of the vessel, as hitherto assumed, wood may be used, in the form of staves, pnt together with hoops, forming a hollow.- bottomed cistern or vat, Awhich, for

many purposes, maybe employed with peculiar advantage.

There are various forms of steam-jacketed kettles well known and in common use, by means ot' which steam-heat is applied for boiling-purposes.

Of these, that which approaches nearest to 4the form here described, is one, for many years, made and sold by one of the undersigned, in which the kettle is 'cast .w11ole, the body part A and the bottom part B together, but otherwise substantially as above repre` sented..

Where there is nothing objectionable inthe contact of the liquid orother contents of the vessel with the iron, thishollow-bottomed cust kettle answers every purpose of a steam-jacketed or bottomed kettle `better perhaps than anyother known to thel public, being strong, safe, convenient in use, eiiicient in the application of steam, and comparatively inex-v pensive.

But where such Contact is injurious, as it is in very many processes in the culinary, and in various manu,-

facturing arts, it has been found unavailable, with any modification as yet applied to it; the principal difficulty being found 'in the fact that in the process of tinuing, porcelain lining, and other like v processes that had been employed for protect-ing the surface of the iron, the dii-ferent parts are subject to n iaterially different conditions, and .as a consequence, to unequal expansion and contraction in the. heating and 'cooling required.

The special object of our invention is to remedy this diicnlty, and thus to make this peculiar form'of vessel available with equal advantage, for all the purposes of a 'steam-jacketed kettle.

This objectiveaccomplish, simply by making the bodyor sides A, and the hollow bottom'B, in the first instance, separate, thus allowing the former to be made of any thin or sheet-metal, or other material, not liable to 'be corroded, as for exampleJ of wood, as already suggested, while the latter, presenting a comparatively small surface, over an equal or very nearly equal thickness of metal, and subject to uniform con ditions throughout, under the operations above indicated, m'ay be readily subjected to any of these processes for protecting it against corrosion.

Whether for the special purpose above indicated, or` any other, we are not aware that this method of forming a hollow-bottomed kettle, by making the body part separate from the hollow bottom, and putting them together in the manner here described, h as ever before been known or used.

That therefore we claim, and desire to secure by Letters Patent-,-is

1. The combina-tion, for the purpose of forming a cal action of the contents of the vessel, with :L body kettle for boiling by steam, of :t hollow enst bottom, or sides formed of sheet-metal, o1' other materiel, of a, fitted to receive and contain steam, with :t body or kind not liable to be so corroded.

sides of sheet-metal, or other thin metal, formed sepav JAMES O. MORSE. rately, and fitted and put together, substantially as GARDNER D. HISCOX. herein described.

2. The combination, for :t like purpose, of such a, Witnesses: hollow cast bottom, having its upper surface tinned, 'Jos G'. E. LARNED, or otherwise protected against corrosion, by the chemi- ELIEf BOWIE.
