. I A. L. FLEURY. Refining Iron.

N0. 3 2:8 Patented Feb. 19, 1861.



Specili cation forming part of Letters Patent No. 3 1,450, dated February 19, 1861.

i e aZZ whom, it may concern:

Be it known that I, ANTHONY L. FLEURY, of the city of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented a new and useful Improvement in Tools Used in the Manufacture of Iron; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification.

Figure 1 is a central longitudinal section of the tool; and Fig. 2 represents a sectional view of the working-hole of a furnace, and illustrates the use of the tool.

Similarletters of reference indicate corresponding parts in both figures.

The tool represented consists simply of a taper tube, A, of wrought-iron, of convenient length for use as a working-tool, having its larger end fitted with a movable cap, B. This construction is more particularly intended for the introduction of salts or other solid matters, which may be introduced at the larger end by the removal of the cap B. Vhen the tube is charged, the cap is screwed on and the tool is ready for use in the same manner as a common working-tool, the smaller end being inserted in the furnace. The heat decomposes or evaporates the salt or substance with which the tool is charged, and the gas or va por eliminated forces itself out at the nozzle or point of the tool by its own pressure, and

in this way is caused to be delivered below the surface of and among the metal or ore, and thus brought into more intimate and diffused contact therewith than when introduced by other means.

It is not necessary here to specify particular substances whose introduction among the iron I propose to effect by the use of the hollow tools. Suffice it to say that they may be used for the introduction of substances containing oxygen, hydrogen, nitrogen, chlorine, carbonic acid or oxide, or any other elements or agents which are known or may be found to combine to advantage with or act advantageously upon the metal or ore,

I do not here claim the introduction of salts or of any other substances among iron or ore during any stage of the manufacture; but,

Having thus described my invention, I claim and desire to secure by Letters Patent As an improved article of manufacture, a

hollow stirringtool, A, provided with a removable cap, B, and otherwise constructed substantially as herein shown and described.
