SAD-IRON..
srRcI'FIOATION forming para of Letters Patent No. 656,088,1iatea August 14, 1900.
A ppnmion inea Apni 12, 1899.
-irons, and particularly to those adapted to burn gasolene gas, the perfect combustion of which is difficult. Such irons are made hollow and they have resting on the bottom elongated, perforated, and open-bottomed burners, which serve simply to mingle the gas and air on the principle of the Bunsen burner, discharging it into the inside of the hollow iron through small perforations, the actual combustion taking place in the body ofthe iron after leaving the burner.
Our invention is directed to the improved construction of sad-irons in the direction of producing the most perfect combustion and, of transferring the greatest quantity of heat to the bottom of the iron; and it consists in the arrangement and combination of parts, as hereinafter described and claimed.
The invention is illustrated by means of the accompanying drawings, in which- Figure l is a vertical longitudinal section through the center of the iron, and Fig. 2 is a cross-section on the line of Fig. l.
A represents the body of the sad-iron, and it is made hollow and in two parts, these parts being held together by means of bolts lo and having interposed between them an asbestos diaphragm ct. This diaphragm divides the interior of the iron into two unequal chambers, the lower or heating chamber having perforations b at the top and j at the bottom to insure the circulation of gas. The diaphragm a and the airfspace above it prevent the heat from getting into the top of the iron and confine it at the bottom when it is needed.v
Restingonthe bottom B, which is preferably of copper, lis the elongated combustionchamber E, whichextends nearly the entire length of the iron. The combustion-chamber E is preferably in the form of a semicylinder with an open-bottom, and it is supported on the bottom by means of supporting cross-bars g, the ends of which turn up and thus secure serial No. 712,719. (No man.)
them in place on the combustion-chamber. These cross-bars, being in the line of the flame and having a considerable surface in contact with the bottom, readily absorb the heat of the flame and transfer it to the bottom. Gas is introduced into the chamber through the pipe t', which passes down through the handle-supporto, through the top of the co1nbustion-chamber,and connects at its lower end with the T connection or spreader h, by which the current of gas is divided and di rected horizontally toward each end of the combustion-chamber. This T connection .prevents the gas from impinging directly on the bottom of the iron and insures an even distribution and combustion.
The escape of the burning' gas from the Ycombustion-chamber is provided for by open# ings f at the top, While Athe spaces between the cross-bars g allow the air to come in at the bottom. In Order to prevent the escape of unconsumed gas at the ends of the combustion-chamber, we stop the ends with plugs @made of Iasbestos or other refactory material, and a lining 0 of the same material is provided for the combustion-chamber.
The handle CZ of the sad-iron is connected with the handle-support c.
In the operation of our sad-iron the gas and air mixed together is introduced through the pipe t', and, dividing in the spreader, it is thrown toward each end of the combustionchamber in a horizontal direction. The ends e and the lining o lsoon become incandescent and the gas is thoroughly burned.
We claim- The herein-described gas-burning sad-iron provided with an open-bottomed, elongated perforated combustionchamber in which the combustion takes place having refractory end walls, conduction-supports beneath the combustion-chamber for raising the same above the bottom of the iron and conducting heat to the bottom, and va gas-pipe for supplying gas to said combustion-chamber,-substantially as described.
