IMPROVEMENT IN PU OD'LING FURNACES.
Specification forming part of Letters Patent No. 43,880, dated August 16, 1864.
To all whom it may concern:
Be it known that I, MORGAN J. DAVIES, of Zanesville, in the county of Muskingum and State of Ohio, have invented a new and useful Improvement in Puddling-Furnaces; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a side sectional elevation of my improvement; Fig. 2, a plan View of the same; Fig. 3, a diagram of a proposed modification of the same.
Similar letters of reference indicate like parts.
This invention relates to the construction of the boshes of the furnace; and the object of the invention is to so form the inner surfaces of the boshes that the said surfaces will serve to hold up in place and prevent the falling down of aprotecting composition or layer, which I employ in connection with my improved boshes, both of which I will now describe.
The boshes of ordinary boiling or puddling furnaces are commonly made of cast-iron, vertical and smooth on their inner or fire surfaces, and so constructed and set in surrounding fire-brick that a current of cold air circulates under the backs of the plates composing the boshes and prevents them from becoming melted.
As a further preventive against the destruction of the boshes, it is common to fix or protect the inner surfaces of the boshes by placing against them a layer or layers of iron ore, in lumps, while a layer of iron scraps is placed upon the bottom or hearth. The ore and scraps are then partially fused, and form a protection for the boshes and bottom under the intense heat to which they are exposed during the subsequent process of boiling or puddling. The fixing or preparing of the furnace to receive a charge for puddling, in
the manner described, is a work of much labor, requires from two to three hours time, and involves the consumption of a considerable quantity of fuel.
In order to overcome the above difficulties, dispense with and save the time, labor, and expense of the usual fixing and the attendant losses of fuel, ore, and scrap-iron, and other losses, I construct the insidefaces of theboshes' A with a series of step-like ridges, recesses, or corrugations, as shown. The projecting and horizontal portions of these steps, ridges, or corrugations serve to hold or retain a protecting composition, which I throw upon said ridges, recesses, or corrugations preparatory to charging the furnace. The position of the composition is indicated in red. The hearth B may be covered or protected with the same composition.
The boshes A may be cast in iron or made of soapstone, or built up of brick or composed of any other suitable material or materials, attached to and placed upon the hearth B in the ordinary manner. The backs of the bosh es, instead of being left smooth, may be corrugated in any desired manner, or as shown in red diagram, Fig. 3.
The protecting compound which I find best .suited for the purpose here named is composed of lime, fire-clay, iron ore, tap-cinder, and iron scales; but any other suitable protecting medium or compound may be employed.
Having thus described my invention,I claim as new and desire to secure by Letters Patent- 1. The construction of the inside faces of the boshes of iron with projecting recesses, ridges, or corrugations, set at any given angle to prevent the falling down of the protecting compound, substantially as herein shown and described.
2. The use of a protecting compound, in combination with boshes that are ridged or corrugated, as above described, all as set forth.
MORGAN J. DAvIEs.
