For machinery for making Horse or Ox Shoes; Ezekiel Davis, Barre, and Samuel Field, Oakham, Worcester county, Massachusetts, October 8.

In the lower part of a very stout frame of cast-iron, a horizontal spindle is to run, in the manner of a lathe mandrel; one end of this spindle is to project through a collar, and to carry a kind of chuck, the face of which is to be grooved, so as to form a. mould, into which the heated iron is to be forced in order to convert it into shoes. This moulding face is to be about sixteen inches in diameter, and the groove about two inches clear of its edge. When horse shoes are to be formed, the indentations for two of them are contained in the circle, two cutters, or chisels, being placed in it to divide the iron; for ox shoes, four such cutters are used. There are to be creasing dies, corresponding with the number of shoes, on which are raised as many projections as there are nails to be employed. A punch, or punches, operated upon by cams, and passing through the moulder are to throw the shoes out of the groove.

In order to force the iron into the moulding groove, there is a roller revolving vertically, the lower end of which roller projects through a collar, and bears against the face of the moulder. The heated bar is to be passed through an opening, or notch, which guides it between the roller and the groove, by which it is to receive its form.

“The invention claimed is the plate, or mould, and the manner in which that, the spindle, and roller, are placed to produce the effect; the punches to throw out the shoe, and the application of water to cool the mould; and the slide to assist in throwing off the shoe.”

We do not see in this machinery any thing calculated to remove the difficulties which have been hitherto encountered in the attempts to make horse shoes by rolling. There has in every instance, we believe, been a considerable waste of metal, and fins have been left upon the edges, which not only increase the waste, but are difficult to remove; and, after all, the horse shoe is not completed by the machine, but has to undergo considerable forging to prepare it for use. We predict, therefore, that it will prove a total failure.
