WALTER DUNKERLno'F WooNsocKET, RHODE ISLAND.
`Letters Patent No. 103,160, dated 'Mag/'11, 1870.
:Menovnn FORGE-nonnen.
The Schedule referred toizrthes Lettera Patent and making partlof the sama Bc it known that I, WALTER' DUNKERLY, of'- Woonsocket, in the-county of Providence and State of' Rhode Island, have invented a new and4 valuable Improvementin Forge-Bonnets and I do hereby declare that the following is" a full, clear, and exact 4description of the 'construction and operation of the same,
reference being had to theannexed drawings making a part of this specification', andl to the letters and tig- `ures of` reference marked thereon.
Figure 1 of' the drawings is a front view ot'- my in- 1 Figure 2 is a central vertical cross-section thereof'. M y invention relates to means for increasing the heat and cconomizing coal ina blacksmiths forge, and con'-, sist'sln the construction of a bell-shaped bonnet lined withfire-ciay, designedto be placed upon thev forge directly overthe tweer. r
The letter A of the drawings represents the forgebonnet made of cast-iron` and lined with tire-clay, b. It is, in-shape, a cylinder, surmounted by a cone, but its horizontal sections areelliptical, the' longest diaml eter being in the linepf the doors c and d, through t which the articles to be heated are introduced. These doors slide vertically.
E -designates thefecding-door, through which coals `are passed. Y
h represents a damper designed to prevent the escape ot' heat, when necessary. `The bonnet may be used either with or without a ehimney.` When the forge is provided 'With a chimney, the bonnet as above described is complete for use,
but when there is no chimney, the sheet-iron pipel l is used to convey o' the products of combustion. v At its lower end, just above the damper, the sheet.-
iron pipe is provided with an inverted funnel or cone@ shaped collar, It, designed-to gather the gases and smoke when the damper is closed, and to convey them off through the draught-openings z z. v i With this bonnet an iron bar can be heated quickly and with great uniformity. Less coal isnecessary to accomplish-the work, and there is no waste. With the bonnet a certain degree ot'neatness is possible about a forge, which `cannot be obtained without it. The lire-claylining serves to retain the heat, and, 'at
the same time, -t-o prevent the cast-iron body ot the bonnet fromv being quickly burned out. i
' What I claim as my inventiolnand desire to securel by Letters Patent, is-
1. 'The forge-bonnet herein described, lined with tire-clay or other suitable material, and provided with Athe feeding-door E, sliding doors c and (l, and damper h, as speclied. A I A 2. In combination witlt'the conical cast-iron forge;r bonnet A, having feeding-door E, sliding doors c and d, and damper h., the sheet-ironfpipe Z, having conical collar k, and draught-openings z z, substantially as shown and described.
In testimonythat I claim the above, I have hereunto subscribed'my name in the presence of two witnesses.
