To all whom it may concern:

Be it known that 1, JAMES FERGUSON, of Bridgewater, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Maghines for Cutting Horseshoe-Nail Blanks; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and tolletters of reference marked thereon, which form a part of this specification.

My invention irelates to improvements in machines for cutting horseshoe-nail blanks.

It consists, inficombination with a shearing apparatus for the purpose of cutting off the nail-blanks from the nail-plate, of a pair of adjustable punches located near the edges of the nail-plate, which is fed between them to the shearing apparatus, for the purposeof cutting out notches or recesses on both opposite edges of the nail-plate, by which the nail-blanks cut off from such a prepared plate are better adapted for their subsequent insertion between the gripers in which the heads and shanks of the nails are shaped. These punches may be arranged so as to descend and rise together, or they may be arranged so as to work independent of each other, as may be required, without departing from the spirit of my invention.

Thefinail-plate isifed by means of rollers, on an oscillating way, toward the punches and shears, and the nail-plate remains at rest when the punches and shears perform their work, during which time the feed-rollers are held stationary.

On the accompanying drawings, Figure 1 represents a plan view of my improved machine. Fig. 2 represents a longitudinal section on the line A B, (shown in Fig. 1;) and Fig. 3 represents a cross-section on the line 0 D, also shown in Fig. 1. Fig. 4. represents a plan view of the nail-plate with its notches.

Similarfiletters refer to similar parts wherever they occur on the different parts of the drawings.

a represents the frame of a cutting-machine constructed in the ordinary way. b represents the driving-shaft, movable in the bearings c c, and provided with cranks d e, the former connected to the link f, for the operation of the shear-frame g on the fulcrum h, and the latter connected tothe rocking lever i by means of usual way. 0 represents a pinion secured to the driving-shaft b, and engaging into the spur-gear s secured to the intermediate shaft t, that is movable in stationary bearings t t.

To the'outer end of said shaft is secured a disk, u, having a crank-pin, a, to which is jointed the connecting-rod v, the rear end of which is hinged to the traversing-block to, provided with a curved slot, w. The block w is movable in the stationary guide 00, that also serves as a guide .for the traversing-block 3 having a pin, 3 projecting through the curved slot 'w, as shown in dotted lines in Fig. 1.

The link Z connects the traversing-block y to the swinging nail-plate guide q, and in this manner a swinging motion is imparted to the said nail-plateguide g from the driving-shaft b, for the purpose of presenting the nail-plate to the action of the shears, so as to be cut 0E in a manner as shown in dotted lines in Fig. 4. To the shear-frame g is secured the movable shearing-jaw g, and to the frame a is secured the stationary jaw g", in the ordinary way.

E E represent the adjustable punches, operated up and down in the adjustable frames F F. These punches are arranged and operated on the opposite sides of the nail-plate, for the purpose of cutting or punching notches on the edges of the nail-plate, as represented in Fig. 4. Each punch is provided with its corresponding die E E, and the punches are shown as being operated by means of the projecting levers G G on the shearing-frame g, or a separate lever may be used for each punch, independent of the other, when it is desirable not to operate both punches at the same time. Springs H H are shown on the punches E E, for the purpose of automatically raising them above the nail-plate as soon as the levers G G cease to act upon them.

The frames F F are made adjustable to and from each other, as well as siclewise, for the purpose of being able to cut or punch the notches from the nail-plate in the exact and desired positions.

I may, of course, use a shear having a linear vertical motion, instead of a rocking mo tion, without departing from the spirit of my invention.

What I wish to secureby Letters Patent, and claim, is-- I The combination, with the oscillating nailplate guide q and its shearing apparatus 9 g g, of the adjustable punches E E F F, for the purpose of punching notches on theedge of the nail-plate previous to its being cut by the shears, as herein shown and described.

In testimony that I claim the foregoing as my own invention I have affixed my signature in presence of two witnesses.

JAMES FERGUSON.
