l Letters Patent No. 104,764, dated .Tune 28, 1870.
'The Seheule referred ico-in these Letters Patent'and making p'att of the same.
Be itknown that I, NATHANIEL .'PLYMPTON, of Boston, of the county of `Suffolk and State of Massachusetts, have invented a new and useful Improvement in Earthen-ware Teapots; and do hereby declare the saine' to be fully. described in the `following specifi- `cation and represented in the accompanying drawing, i of `\vhicl1 l Figure lis side elevation; Figure 2, a vertical section; and
Figure 3, 'a bottom view-oan earthen-ware tea-pot,
provided with -my improvement. A
. `Common earthen-ware tea-pots, such `as arefor use on stoves, mostly, if not.entirely,are made with'a concave or dished bottom, having an encompassing lip or ,ilange tocome intocontactwith thetop of the stove.
When the tea-potreste on a h ot Stove, the bottom lip is, generally speaking, the only part in contact with the stove, and,\co"usequent1y, rst receives the -hcat `radiated fromsnch top. i The heat absorbed by the Harige, when `the tea-pot is first. set on therstove,..will suddenly expand the y flange,ra dially` and longitudinally, so as to renderit liableto crackfasnnder, 'or awayfrom those'parts of' the teafpot which` maybe either around or encom'- passed by snch flange. In consequence of this sudden expansion of the ilange,the'botton1 of the tea-pot is very apt, sooner or later, to become cracked, so as to vcause theves'sel to leaks4 l [have found that by` notching the flange transl y versely,or grooving the bottom and the -flange'v da` Inetrieally,-the4 danger'of` cracking or breakage of the bottom, through sudden expansion o f the flange by heat, will be greatly reduced, if net entirely obviated. The drawing exhibits an earthen-ware tea-pot, in
which the bottom A, with its encompassing sustain-A ing-lip or flange at, is exhibited as grooved diametrically by a series of grooves or channels, b'b, crossing one`another, and extended through the flange a. The
flange thus becomes separated into sections, each being free to expand independently, of the others, or those next toit. p
The flangealone may be notched transversely, but I prefer to score or groove both the bottomland the flange, as, by so doing, the chance of cracking the bottom, through the-sudden expansion of the ilange, will v not only be largely diminished, if not entirely prevented, but the heating of the liquid contents of the tea-pot or vessel ,will be facilitated thereby, as the thinner parts of the bottom, that is, those over the grooves, will absorb and partwith the Aheat'q'uicker than the thicker or intermediate portions thereof.
In. other respects, I make the tea-pot in the ordinaryV way, its handle being shown .at c, and spout or nose at (l.
I claim-'- As a 'new' or improved manufacture, an earthenware'tea-pot, having its .bottom notched or grooved, substantially as described.
