METAL-BENDING TOOL.
SPECIFICATION formingpart of Letters Patent No. 225,415, dated March 9, 1880. Application filed November 11, 1879.
To all whom it may concern:
Be it known that I, SAMUEL PATTERSON, of Altoona, in the county of Blair and State of Pennsylvania, have invented a new and Improved Metal-Bending Tool; and I do hereby declare that thefollowing is a full, clear, and exact description of the same.
. My invention has for its object to provide for use of blacksmiths and others having occasion to form angular bends in metal bars or plates a tool which will enable the work to be done much more easily, quickly, and economically than by the ordinary means-to wit, a hammer, anvil, and vise.
To this end I construct a tool as shown in accompanying drawings, in which Figure 1 is a side view, and Fig. 2 a top or edge view, of my improved bending-tool. Figs. 3, 4t, 5 illustrate,'in part, the difi'erent operations of bending a metal bar with the aid of said tool. Fig. 6 is an edge view of a bar bent by aid of the tool.
My improved metal-bending tool is of very simple and inexpensive, but durable, construction. It is formed of a bar, A, which may be made of steel or of wrought-iron having a steel-faced head. One end of said bar A has the proper size to adapt'it fora handle, a, and the other is broadened into a flat head, 0, having square corners d and a narrow transverse slot, e, whose lengthor depth is about half the width of the head.
The manner of using the tool is as follows: The blacksmith, having heated red-hot one end of the metal bar which he desires to bend, takes it from the fire, holding it by the tongs in his right hand, and the tool A in his left,
but with the head 0 of the latter resting on the anvil edgewise, so that the slotted side is uppermost. He drops the heated end of the metal'bar B into the slot 6, and then turns the tool flat on the anvil, but with its head a overhanging the edge of the latter and the metal bar projecting through the slot the distance of the required length of the bend to be produced. He also holds the bar pressed against the side of the anvil, so that it will not drop through the slot while the upper portion is being bent over. The tool is then turned on its side, Fig. 4, and drawn back upon the anvil, and the hammer used to reduce the iron to the desired shape, which can be done with a few strokes. The bar is next detached from the tool A, and the other end heated and bent in the same way as the first, the position of tool and bar in the last operation being as represented in Fig. 5. Thus, at two operations and with three bends, I efiect what ordinarily requires from eight to ten heats, and the bends produced are of uniform size and shape, in place of being irregular when made in the usual way.
The bending operation causes the bar to bind or fit tightly in the slot 6, and in order to force it out of the same I employ a forked device (not shown) which is adapted to straddle the back of the head of the tool. A light tap on such device will cause the bent iron to drop out.
As shown in the drawings, Figs. 3, 4, the head of tool Ahas offsets or shoulders f. The
function of the shoulders is to prevent reduction of the thickness of the iron under the trip-hammer, which is brought into use in heavy work.
I am aware it is not new to form a metalbending tool by providing an iron or steel bar with a transverse slot, such being the construction of some kinds of saw-sets. I do not, therefore, broadly claim a tool thus constructed.
Having thus described my invention, what I claim is- The tool A, having a head, 0, provided with transverse slot 0, the part beyond the slot being set to one side equal to the thickness of the metal to be bent, as and for the purpose described.
