IMPRO EMENT IN THE MANUFACTURE or TEA-POTS.

To WHOM IT MAY CONCERN: a r

Be it known that I, DOUGLAS B. WOODWORTH, of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Britannia Tea-Pots; and I hereby declare the following to'be a full, clear, and exact description'therecf, reference being bad to the accompanying drawing, making part of this specification.

My invention relates to a provision on tea and cofi'ee pots, of Britannia or other 'fusible alloy, of a foot of copper, brass, or other refractory metal, which foot ishwholly external to the p'ot 'proper, and. being brazed or soldered in the receding angle of-a shallow dropor pit, is protected from separation by a very slight quantity of liquor in the vessel. I V I The accompanying drawing is .a partially sectionized side elevation of aitea-potembodying my invention. The body, A, of the pot of-Britannia or. other fusible metal, has a pi t'or dr'op, B, whose receding or re-entrantwangle,C, receives the'u pperedge of a ring .o riannular foot,D,' of brass or other-metal, whose melting point is above the heat of an ordinary stofve-top. .e'lhe upper edge ofzthe'foot' D i s'seeu red vvithin said receding angle of the body by'brazing or soldering. p -i It will be seen that the foot D is whollyex ternal to the vessel, so that the interior of the latter may be wholly of one material, and. therefore free from galvanic action incident to composite tea-pots, as heretofore constructed. It is also apparent that the line of junction of the foot and body, being precisely in the plane of the shallow pit or depression B, will be protected from melting by the smallest quantity of liquid in the vessel.

Thehard-metal foot D may be formed in various ways, according to taste, utility, or convenience; thus, its lower edge may be turned in, as shown in the illustration, or may terminate in a number of projections or distinct feet.

Iam aware that it is not new to make the bodies of tea-pots of fusible metal and their bottoms of hard metal.

I claim herein as new,'and of my invention- A fusible metal pot-body, A, having the shallow pit or depression, B, and an annular foot, D, of non-fusible metal, brazed or soldered within the receding angle 0 of the pit, at or near the plane of the latter, external to saidbody, as and for the purpose set forth.

In testimony of which invention, I hereunto set my hand.

and wholly D. B. WOODWORTH.
