IMPROVEMENT lN MAKING EDGEuTOOLS.

Specification forming part of Letters Patent No. 22,466, dated December 29, 1858.

To @ZZ whom it may concer/t:

Beit known that I, VILLTAM XVnrrE, of Xewark, in the county of Essex and State of New Jersey, have invented a new and improved mode of making edge-tools and other articles from wrought-iron and steel without the usual process of welding and forging or swaging, as now practiced; and I do hereby declare that the following is afnll descrip* .tion thereof, reference being had to the ac companying drawings, and to the letters of reference marked thereon.

Figure I is a plan of one side of a mold for an ax, A A being half of the recess for the reception of the melted or liquid metal. C is the core-pin to form the eye of the ax; E E, the gate or spr ue or passage-way for the metal; F F, the steadypins.

Fig. 2 represents the opposite side of the mold, B B being the other half of recess A A, Fig. l; D D, the core-print to fit the other half of core-pin G, Fig. l. G- G are holes for steady-pins F F, Fig. l.

Fig. represents an edge view in section of` Figs. l and 2, showing the two halves closed together, the dotted lines rel-)resenting the recess A A B B for the reception of metal to form an ax, hammer, or other article.

In Fig. 4, (seen in Fig. 2, 1 2 3 4 5 6 represent the whole ax in a rough state as taken from the mold,with the gate or sp1-ue attached. The red lines divide or distinguish between the head or eye part of' ax and the bit 0r edge part. Each part can be made separate and dist-inet from the other by the use of a mold the cavity of which shall be the shape of the part desired.

The nature of my invention consists in pouring from a crueible or other vessel into a mold wrought-iron or steel, or both in combi nation, while in a melted or liquid state, and thereby forming a whole 0r a part of an ax, hammer, or other article, the cavity of said mold being-the shape or form of the article l desired.

together with a band, clamp, or other device and place it in a convenient pla-ee for the reception of the metal, which I reduce to a liquid state by any known process. I build a furnace of fire-brick three feet and four-inches deep, two feet and six inches long, and one foot-"six inches wide, and attach thereto a pipe by which I convey a blast of wind, either hot or cold air. I then eut my iron or steel into small pieces and place it into a Crucible, and place the same into the furnaee,\vhich is tllled two-thirds full of coal or other fuel, and start my iire, applying` blast sufiieient to reduce the metal to a melted or liquid state. I then pour the liquid metal into the cavity of the mold, using such core-pins and stops as are necessary to obtain the required-shape.

Two qualities of metal can be united in the same article by the following method: I place the mold with the edge part of the an downward, as in Fig. 3. I now pour into the cavity of the mold a very flue quality of caststeel until it rises up to or a little above the line H, and then from another erucible I pour a mixture ofiron and steel or other meta-l ot' inferior quality, with which I iill up the head or eye part of the cavity, being very careful to pour from the second crueible at the same time that I cease pouring from the first, so that the stream may not be broken, which will allow the two kinds of metal to unite at or near the line I-I, and thus form a solid ax from two qualities of metal or from two dit'- ferent kinds of metal-as iron and steel-without welding and forging or swaging.

I am aware that ingots of steel and iron are now formed by pouring the melted liquid into molds. I do not claim for the purpose of forming the ingot.

I do not claim the manufacture of iron or steel, nor the remelting of the same, either new or old; but

XVhat I claim as my invention, and desire to secure by Letters Patent ot' the United States, is-

The use of wrought-iron and steel separately or combined while in a melted or liquid state, for the purpose of forming into shape axes and other articles without the process of forging, welding, or swaging, by the use of a mold the cavity Ot' which is the shape or form y of the article desired, as set forth in my specifieation. Y

VILLIAM VHITFJ.
