IMPROVEMENT iN. TEA AND COFFEE POTS.

Specilieation forming part ot' Letters Patent No'. 35,457, dated .Iuuc 3, 1R62.; Reissue No. '2,01 3, dated June 27, 1865.

To @ZZ whom it may concern.' V

Be it known that I, EDWARD B. M ANNING, of Cromwell, in the county of' Middlesex and State of Connecticut, have invented a new 4and useiul Improvement -in Tea and Coffee Tots; and I do herebyydeelare the following', v when taken in connection -with the accompanying drawings, and the letters'of reference marked thereon, to be a full, clear, and exact description ot the same, and which said drawings constitute part of this specification', and represent, inf e Figure l, a perspective view, and in Fig. 2 the bottom and lower portion, of the body as formed to be united with the upper portion l of the body. y

Britannia metal, as is well` known, is one of the cheapest and at the same time one' of the most beautiful metals for the construction of tea and'eoii'ee pots, as its ductility permits its easy formation -to any required shape, and at the same-time is capable' of receiving 'a high polish, but from its liability to fuse at a low degree ot' heat and from its inability to with- `stand the required pressure, it is not adapted to uses where necessarily brought into contact with highly-heated surfaces, as in the constructionof tea or coi'ee pots, which are generally placed upon a 'highly-heated stove or range for the purpose of drawing or boil- ,ingl tea or coee. Other metals capable of sustaining a greater heat and pressure-as blocktin, Src-,less beautiful in appearance, have, therefore, to a very considerable extent been -used for such purposes.

My invention, designed to overcome these dilieulties, consists in constructing the bot tom and lower part of the body of tea or cnffee pots from a metal' fusible only at a high degree of heat and capable of withstanding a' great pressure, an d the upper part of the body from britannia, and uniting` the two parts so that the bottom may be iiat and placed directly upon a heated surface-as upona range or stovewithout injury to any part of the tea or 'coii'eepoty To enable others skilled in the art to construct myimproved tea or coffee pot, I will Vproceed ftoi'uily describe 'the same as ill-Ausl trated in the accompanying drawings.

' The upper part, A, of the body is made of` "britannia, and may be of any desired form 4 into which the metal is capable of being Wrought. The lower part, B, of the body is ofiron or any other metal capableof sustaining a high degree of heat and pressure with-l .out injury, andl is struck upto correspond with the forni of the upper part of the body. The part B may be tinned and polished so as to be rendered nearly as smooth, bright, and

.elegant in its appearance as britannia itself,

and then the whole vessel will harmonize as it made of the same metal. The lower part, B,

of the body is united to the upper or britau- 'tea pots from beingV injuriously a'cted by the heat by coinbiningsome other metal 'with them, such result has been sought to be obtained either by the use of feet or a ring or ledge placed under the vessel,'or by making the bottom surface of copper, brass,'orsimi' lar metal. In the former cases, when feet or a ring or ledge .are used, the bottom of the coffee o'r tea pot is raised vabove lthe range or stove.v KThis interferes with the Aquick and .proper action of steeping or boiling in such vessels.

When the bottom surfaces of such articles have been made of firmer meta-l, the j'oint between vthe two different kinds of met-alhas been, in order to preserve the beauty and ar` tistic appearance of the pot, either directly on the edges of the bottom or just above it, so that the` heated surface of the' stove, te.,

'would act directly ,on's'ueh joint to unsolder it or melt'the britannia body, or `would be'so near suoli joint as to produce the same effect of rendering the vessel leaky and useless. All such combinations have either raised the vessel vfrom the heating surface, thereby rendering the vessels less-adapted for the 'purposes rtor which intended', or the attached bottom has been. extremely liable, Vit` not certain, to become unsoldered andleaky-whenever the pot was applied to its appropriate uses.

By my improved form oteonstruetion and.

ot' combining the firmer metal with thebritannia, the bottom ot' the Vessel can be made and 'left flat, so as to come-in close contact with 1'he range, &c., thereby causing the operation steeping, the., to\ be quickest, and in the preparation ot tea and coffee the quicio ness with which the strength is drawn from the substance is very import-ant and essential to the'goodness ot' the decoction produced, and alldanger or liability of the joint being loosened and the vessel rendered leaky is etfeetually prevented and obviated.

By heavily trimming the lower partof the vessel and polishing the same I also produce a vessel of as neat and elegant appearance as if made entirely ot' britannimbut at the same `time having all proper resistance to heat and pressure where such. 'resistance is necessary.

Thus myinvention or improvement does not consist in simply combining with oruniting to bri'tannia, metal another metal which will 'bear a greater degree of heat, but in oonstructing the lower and bottom part of the pot from such other metal7 by swagingg,` or otherwise, into any desired artistic shape corresponding with the shape ot the britannia metal, and in uniting the two metals byplacing the joint or place of connection between the two so far above the bottom surface that while said bottom surface may be flat and in direct contactwiththe heatin g-surface, neither such joint nor the'britannia metal vwill be in4 juriously affected by h eat.

Ido not claim the forming of pots and vessels of di'erent kinds of metal, as this has been before done; but

What I claim as my invention, and desire to Secure by Letters Patent, is-

The herein described'tea or coffee pot, in

which the bot-tom and lower portion of the body is constructed of hard metal-as iron united to a britannia body, in the manner described-when `the said hard-metal-bottom and body are formed in the manner described and united to the brtannia body a suflicient distance from the bottom to protect the britan nia'I from the effects of heator other injury'v as and for the purpose specied.
