i IMPROVEMENT m WELDING CAST-WON T0 MALLEABLE IRON on STEEL.
Specification formin g part of Letters Patent No. 5,331,1dated0ctober 16, 1847.
To all whom it may concern.-
Beit known that we; WILLIAM MARTIN, Jr. and MARK FISHER, of Newport, in the county of Pen'obscot and'State of Maine, have made a new and useful Improvement in the Manner'of Uniting or Welding Cast-Steel and Cast Iron; and we do hereby declare that the following is a full and exact description there- A of. y
Various attempts have been made to unite or weld cast-steel and steel of other kinds or the iron in amolten state upon the steel or been attempted has been to prepare a plate or other duly formed piece of cast-steel or of other kinds of steel or of wrought-iron by brightening" the part with which it was intend ,ed the cast-iron should unite and coating it with calcined bora-x or other analogous flux. The piece thus prepared has then been laid in its proper place in the mold in which the casting was to be made, and the molten iron has then been poured in upon it. The results of uncertain and unsatisfactory. In some cases the union has appeared lobe perfect, but in a very large majority of cases the union has been extremely partial, and has most frequently failed entirely. The consequence has been that after muelr loss the procedure-has beenabandoned, which, if successful, would have In our improved process we prepare thejplate or piece of cast or other steel or of wrought iron in the manner above described, brightening its surface, coating it with calcined borax,
and laying it in theliask or mold. Thus far there is not any novelty in our manner of proceeding.- Our invention consists in the man- 'ner of forming the gates or jets through which the molten iron passes into the flask, which is such as that it shall not be poured directly on unite, but that it shall flow over its prepared surface laterally, and be made thereby, as it 7,
were, to wash it. By-this means fresh particles of the molten iron are brought into successive contact with every portion of the face of the steel or wrought-iron, and wbile the flux protects the metal from oxidation all foreignmatter is completely removed, andtho union of the two metals is perfect.
In the molding of some art cles itewill be are a number of similar articles in the flask' every competent founder will be able so to arrange the jets as that the molten metal will pass from one prepared piece of steel or iron is to the other in the first instance, and as the flasks fill the articles will be protected with-v I 1 out the necessity of any receptacle for waste i o metal, all which will be readily understood I the molder.
Having thus fully described the natuieof our improvement in the process of uniting o'r; welding cast-steel or steel of other kinds or I wrought-iron with cast-iron, we do hereby dcclare that we,do notclaim the uniting of the 1 two portionsof metal witheachotherbymerely pouring the cast-iron uponthe prepnredpiece I of steel or of wrought-iron, this having beenv frequently attempted; but we limit our claim i v to improvement to the so forming the jets f 1 through which the molten iron passesintothe flasks as that the molten metal shall flow lat-j, erally over the surface of the prepared steel or.
prepared wrought-iron, for the purpose and substantially in the manner'herein fully made known. i WM; MARTIN, JUN.
