Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. No patent drawing is available. This patent is in the database for reference only.
For a Furnace for Heating Bar Iron with anthracite and Bituminous Coal combined; Henry Burden, Troy, Rensselaer county, New York, October 14, 1834.
"The patentee states that the common method of constructing furnaces for heating bar iron by anthracite is to make them about three feet wide, and four or five long, with grates of these dimensions, and a door at one end for admitting the fuel, and the bars to be heated; the grates have on them a layer of three or four inches, in thickness, of ignited anthracite, upon which the bars are laid; but as flame from this fuel will not fill the space between the iron and the arch, and the heat is unequally distributed, the draft through the grate being more obstructed in one part than in another, the bars are frequently overheated, burnt, or melted, in spots.
To remedy this defect, the improved furnace is lengthened about one foot, and furnished with a door at each end; the anthracite is laid on the grate as usual, and when the bars are heated to such a degree as not to endanger their burning. the binder door is opened, and a small portion of bituminous coal thrown into the back part of the furnace, which, flashing into flame, fills the furnace therewith as it passes over the iron in its Way to the chimney, and equalizes the heat of the bars.
The improvements claimed are:
First. Making the furnace with a door at the back end, so as to admit of the bituminous coal being put into the back part of the furnace.
Secondly. Using the bituminous coal on a part of the grate at the back part of the furnace, reserved for that purpose, which gives the coal an opportunity of ignition, as well as could be by a reverberatory or puddling furnace, before it comes in contact with the iron.
Thirdly. In combining the use of anthracite and bituminous coal, for the purpose of heating bar, or other iron, at the same time igniting each in separate parts of the furnace.
From the nature of the thing, as set forth, and the known talents and experience of the patentee, we have no doubt whatever that the foregoing is a real and great improvement in the process to which it appertains."
