UNITED STATES PATENT EETCEo i BENJAMIN HOSKINS, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN FIRE-PROOF SHUTTERS.
Specitication forming part of Letters Patent No. 146,533, dated January 20. 1874; application iiled December 18, 1873,.
per, and sheet-iron, with a layer of substances containing water in a crystallized state-such as alum and sulphate ofiron--m ixed with coarse Hour to forni a paste. The heat, dissolving the crystals, is thereby keptfronl burning the wood. Y
In the drawing. Figure l is an inside elevation of my improvement in tire-proof shutters; Fig. 2, an outside elevation thereof; Fig. 3, a vertical central section taken on line X X,
rig. 1.
A A are the stiles ,B C l) the rails, and F F the panels, of an ordinary shutter. E E are the hinges, and J the bar-lock. Alum, suitably pulverized, in about two parts, is mixed withabout one part of coarse iour. Sufiicient water is then added to form a paste of a consistency to be spread on the outside of the wooden shutter, as shown at a, Fig. 3. One or more sheets, b c, of tlreproof paper is then laide over the paste a, and then. the outside S Vand edges T are covered with sheet-iron, suitably fastened with nails in the usual manner.
The paste and tire-proof paper may extend over the edges T of the shutter, if desired, to render those parts more secure.
The re'proof paper is ot' the saine kind as patented by Richard U. Piper, No. 135,153, J anuary 2l, 1873; and is an article Well known in the market.
A shutter thus made is found, by a practi cal test, to withstand a great heat brought against the outside, and aizords about the saine protection as the corrugated shutter, and is intended to be substituted for it. Further than this, the cost of manufacture is much less, and they are more easily tted to a building, inas much as the wood-work .can be fitted before the tire-proof material is put on.
I claim, and desire to secure by Letters Patent ot' the United States- A shutter, consisting of a suitable wooden frame, B C D F, a paste made of alum or other crystallized substances, containing water and coarse flour, the tire-proof paper 1) c, and the sheetiron S, substantially as and for the purpose set forth.
BENJAMIN HosKiNs.
