IMPROVEMENT IN FURNACES FOR HEATING IRON BARS, &c.
Specication forming part of Letters Patent No. 136,667, dated March 1.1, 1873.
To all lwhom it may concern.-
Be it known that I, JOSEPH PARDoE, of Quinsigamond Iron-Works, in Worcester, in the county of Worcester and State of Massachusetts, have invented a newand uset'ul Improvement in Furnaces for Heating Iron, of which the following is a specification:
Furnaces for heating bar-iron for rolling out rods for manufacturing wire and similar purposes have hitherto been made with a single tire in the front part of the furnace, and with side openings for introducing the iron, the iron thus being placed at 'right -angles with the course of the flame. This construction has been found objectionable on many accounts, as it does not allow of the perfect consumption of the gases, and the bars of iron, being thus placed transversely to the course ot the flame, are not as readily heated as when the ame penetrates bars laid parallel therewith; and this invention consists in the arrangement of two separate fires in connection with the furnace-hearth, as hereinafter set forth and described. l
In the accompanying drawing, Figure 11s a top or plan view. Fig. 2 is a vertical se'ction of Fig. l taken on the linea' x. Fig. 3., Sheet 2, is a front elevation. Fig. 4 is a vertical section taken on the line y y of Figs. l and 5. Fig. 5 is an end elevation.
Similar letters of reference indicate corre- -V spending parts.
' heated are of a length corresponding with the length of the hearth, and are introduced through the apertures E E at the front. These apertures are closed by means of the dropdoors F F, which are actuated by means of the levers G G. Two tires are thus arranged, one on each side of the furnace-hearth, and are fed alternately with fuel, so that the gases from the fresh coal of one fire will be consumed by the heat from the incandescent coal of the oppositetire. The iron is placed length- Wise of the hearth, so that the flame and heat pass between the bars and lengthwise thereof, instead of first striking the sides of the bars, as in ordinary furnaces. The iron, besides being placed parallel with the draft, may by this arrangement be cut in longer pieces than where it is placed transversely of the course of the ame. This results in a material saving in stock, as well as in time. By having two tires arranged in this furnace I am enabled to introduce the iron through the right and left hand doors alternately, and keep it in two separate piles, one exposed to tire of the fresh fuel, and in the process of gradually heating, and the other exposed tothe heat of incandescent fuel, and ready to be withdrawn and rolled. In this manner l am enabled to keep the rollingmill constantly' running, instead of being compelled to stop the rolls occasionally to await the action of the lire. This also results in a material saving of time and money. H H are apertures for the introduction of fuel into the furnace. The furnace is inclosed with iron plates and irebricl; walls, bound together by rods through the eye-lugs J. As regards the provisions for insuring durability, and the construction of hearth and walls, this furnace need not differ from other furnaces constructed for the same purpose.
Having thus describedmy invention, I claim as newaud` desire to secure by Letters Patent- The combination of the furnaces B B with the hearth A, arranged substantially as shown and described, for the purposes set forth.
JOSEPH PABDOE.
