M. FISHER AND WM. MARTIN, JR, on NEWPORT, MAINE.
IMPROVED PROCESS FOR WELDING CAST T0 WROUGHT IRON 0R STEEL.
Specification forming part of Letters Patent No. 6,054, dated January 23, 1849.
To all whom it may concern.-
Be it known that we, M. FISHER and WM. MARTIN, J r., of Newport, in the county of Penobscot and Sta t'e of Maine, have invented an Improvement in Welding Cast-Iron with Steel or Wrought-Iron and [do hereby declare that the following is a full, clear, and exact description ot'the princi tleorcharacter which distingnishesitt'romullotherthingsbefbre known, and ol the usual manner of making, modifying, and using thesamc.
The nature of our invention consists in preperly heating the steel or wrought-iron before the cast-iron is poured upon it, as described in a patent granted to us dated the 16th October, 1847, upon which this isan improvement.
For small pieces of steel-t ha is, when the surlace is small and the pieces thin-we find no difficulty in welding by our process as patented; but for welding large surfaces of steel to castiron we have found that process to be uncertain and expensive, on account. of the great quantity of cast metal it was necessary to pass over the steel before it become hotenough to enter into combination with the iron. To obviate this uncertainty and expense, in addition to our former process, we beat the steel to a bright red heat before pouring the;
iron upon it, and instead of running off the surplus iron necessary to use by the old process into a recess or cavity in the mold, weallow it to run off througha hole or runnerinto a ladle, and repour it through the same gates as at first, thereby having touse little more metal for welding the largest surfaces than would be required to cast such. pieces when no steel is welded upon them. During the time necessary to heat the steel in al'urnace in the ordinary way, place it, close the flask, and to get all things ready to pour the iron, the steel becomes. much oxidized, cooled, and the sand around it dried, and the result is thereby-rem dered uncertain. We therefore adopt the .following mode: VVe'form a cavity in the sand, which surrounds the steel either under or against one side of the steel oriron, which is opposite the surface to be welded, said cavity being of such a depth or thickness as wejudge will hold a sufficient quantity of melted iron to heat the steel to a bright red heat by the timewe get ready to pour the iron which is designed to be welded to and form a part of the piece. WVe then place the steel over or against this cavity, the steel being somewhat larger than the pattern by which the cavity is made, so as that the steel may have sand to rest. its'edges upon,
and to keep apart the metal which is poured onto the two sides 'of the steel. After having thus proceeded, we pour by a separate spt us or gate into the recess or cavity above named, underneath or against the side of the steel, a quantity of melted iron, until the iron has entiiely fidedthe cavity and touched the steel on the lower or back surface, as the case may be.
This we do after the flask is closed, when the form. of the work will admit of it. When it will not .we first so pour and close the mold atment, what we claim therein as new, and for which wodesire to secure Letters Patent, is-
'1. Heating the steel or wrought-iron to which the cast-iron is to be affixed, beforecasting the melted iron upon it, by means ot' a portion of melted iron poured against that side of the steel which is not to be attached to the finished article, substantially in the manner, and for the purpose set forth.
2. Repouring the metal upon the steel, as described, by which much saving .in the cost of melting more iron than is required for the
