UNITED STATES PATENT OEEIoE HENRY H. PARSONS, OF HOOSIOK FALLS, NEW YORK, ADMINISTRATOR OF THE ESTATE OF EDWIN F. HURD, DECEASED.

IMPROVEMENT IN MACHINES FOR MAKING AXES.

Specification forming part of Letters Patent No. 121,172, dated November 21, 1871.

To all whom it may concern:

Be it known that EDWIN F. HURD, formerly of Canton, in the county of Hartford and State of Connecticut, now deceased, did in his lifetime invent a certain new and useful Improvement in Machinery for the Manufacture of Axes; and that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing making a part of this specification, in which- Figure l represents a perspective view of the machinery as arranged for practical operation. Fig. 2 represents a longitudinal vertical section through the anvil of the trip-hammer. Fig. 3 represents a transverse vertical section through the drop-die and bed-die, showing the form of said dies and the position of an ax-blank being pressed between them. Fig. 4 represents a transverse vertical section through the drop-arm and bed of the machine, and showing how the former is forced into or through the' ax-blank to form the eye of the ax. Fig. 5 represents an elevation of the drop-die and bed-die, showing how the partially-completed ax is formed and flattened between them. Fig. 6 represents a transverse vertical section, showing how the drop-die is held to the drop-plate. Fig. 7 represents a longitudinal vertical section through the arm l and its base l', and through the bed-plate, to show the ax is driven off of the handle or former. Fig.

8 represents in perspective a slotting or scoringtool and supporting-block or anvil, for` scoring the blank for the insertion of the steel, or for starting the opening for the eye of the ax or holding-iron.

Similar letters of reference where they occur in the separate iigures represent like parts in the drawing.

The entire machine is represented in Fig. 1, and the details of the machine are represented in Figs. 2 to 8.

Letters Patent of the United States No. 57,142 were granted to EDWIN F. HURD on the 14th of August, 1866, for a machine for making axes, in which many of the features of the present application may be foiuid. The present application may be regarded as an improvement on his own former machine. The machine as patented was designed for making ax-blanks out of two pieces, which were previously shaped under drop-dies and then welded together, with a tool or former placed between said pieces to form or to leave an opening out of which to form or shape the eye of the ax.

As the present machine is designed for making the ax-blank of a single piece of metal, it involves a decided change of devices and dispenses with much of the intricate operations of the patented machine. The present machine, too, Without being so complicated and expensive as the patented one, is in reality a double machine, or one in which two Workmen at the same time maybe advancing two separateaxes through the series of operations necessary to put them into finished axes, except the grinding, and without interfering with each other.

To enable others skilled in the art to make and use the invention, I will proceed to describe the same with reference to the drawing.

Of the trip-hammers A A and their anvil or die-blocks B B they are duplications of each other, and are the same and for the same purpose as those described and shown inthe patent above mentioned, viz., to shape and true the edges or cutting-ends of the axes as well as to flatten and shape the pole or head ends, and they need not be further described. Upon the bed or frame of the machine there is an anvil-die, C, made adjustable as to height by means of a Wedge, a, underlying it. Upon this anvil-die the ax-blank b is placed, and by means of a dropdie, D, the ax blank is partially shaped or formed, said dies havingin their faces the counterform given to the blank. This mechanism is seen in Fig. 3. From these dies the partially-formed ax or blank bis taken and placed upon the bed or rest E, and a tool or punch, F, is placed upon it at the point Where the eye of the finished ax is to be. As the platen G ofthe machine, which carries several of the drop-dies, comes down, its projecting arm H strikes the top of the tool or punch F and drives it through the blank, as shown in Fig. 4.

The blank may be then taken to the anvil-block or die I and laid flat thereon with the tool, punch, or former F still in it, and there it is flattened and shaped on its sides by said under die and a drop-die, J, that is brought down upon it. The drop-die J is secured to its carrier G by hooked bars c taking into a groove or grooves therein, said hooked bars being adjustable by a slot and set-screw, as at d, as seen in Figs. 5 and 6. The ax b, quite formed and complete, but still on the punch-tool or Jformer F, is taken and placed on the bed E, as seen in Fig. 7, and the forked arm K connected to the carrier G comes upon the edge of the ax, each side of the punch F, and drives down and loosens the ax therefrom. The eye of the ax is nished and smoothed by the reciprocating former e, which is the same as that shown in the patent above referred to, and need not be specially described here. Upon the machine as now improved there is a scoring or slotting tool, j", secured to and moving up and down With the carrier G, and may have side projections i i. This tool may be used for scoring or. slotting the blank for the reception of the steel that is to be Welded to it; and it may be used for starting the hole through the blank (which hole is afterward shaped into an eye) and prepare it for the after operation of the punch F, which is driven through the blank. Under this scoring-tool the support or ledge E forms a bearing for the axblank. Though the carrier G is but a single piece it carries the devices in duplicate, so that an operator standing one on each side of the machine matrT use it for shaping and forming axes Without interfering with the one on the opposite side ofthe machine. The same bed, frame, and gearing serves for the double sets of dies and enables double the Work to be done upon the machine.

Having thus fully described the invention of said EDWIN F. HURD, what I claim therein as neviT in itx-machines, and desire to be secured by Letters Patent, is-

l. In combination with the carrier G and bed E, the arms H and K, the iirst for driving the punch through the aX-blank and the other for releasing therblank from the punch, as described.

2. In combination with the carrier G and support E', the scoring or slotting-cutter f, as and for the purpose described.

3. The arrangement upon the same bed and frame, and With a single carrier, G, of a series of anvil and of drop-dies, so that an operator on each side of the machine may at one and the same time put an aX-blank under the several successive operations to form it into an ax Without interfering With each other, as described.
