IMPROVEMEN'T'IN MACHINES FOR CUTTING NAILS.
Specification forming part of Letters Patent No. l35,915, dated February 18,1873.
To all whom it may concern:
Beit known that we, SAMUEL P. HoLLIs and HARVEY B. GHEss, of the city of Pitts declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure 1 is a perspective view of the cutting portions of a nail-machine, showing our improvements. Fig. 2 is a plan View of the cutting-knives. Figs. 4, 7, 8, 10, 9, l1, and 12 are cross-sectional views of varieties of nail-plates that can be used in our process of manufacture. Fig. 5 shows a fragment of nail-plate, showing by dotted lines where the nail-blanks are cut from it.
Our invention relates to the manufacture of that class of nails wherein the head. of the nail is disproportionately large to the size of the tang. Our invention consists, in
a novel arrangement and construction of blades,spring, and guide in a nail-machine, whereby we are enabled to properly cut nailplates rolled a little in excess of the length of the nail-blank desired, and having a rib on both faces of the opposite edges, the thick-- ness of the plate between the ribs being uniform and. equal or about equal to the thickness of the tang of the finished nail. such plates we cut the nail-blanks with tangs -of tapering form, and secure from the ribs a large body of metal, short in length, from which to swage the heads.
In order that those skilled in the art may make and use our invention, we will proceed to'describe the manner in which we have carried it out.
Referring to the accompanying drawing, A and A are the bed-knives, and B B arethe The cutting-knives B and B are so formed and arranged that neither their front nor lower surfaces are on the same plane. knife on its front and lower edges reccde from the lines of thehead-cutting knife, forming an obtuse angle between the lines of the cutting-knives, both onthe front and bottom. The bed-knife is made in two pieces, A and From The lines of the tang-cutting,
A, which are so formed that the edge of A shall be parallel to the edge of B, and the cutting-edge n of the knife A shall be parallel to the front line of the knife B. The head- -cutting portion of the bed-knife A is made so deep and heavy, in order to withstand the blow necessary to cut the rib a of the nailplate, that its bottom rests on a line with the bed-die. shown, so that theline of its cutting-edge is below that of the knife A about the distance of half the thickness of the rib a, and the knife A, from the groove t outward, is made about on a'line with the front edge of the knife B.
Alongside of the knifeB is a gage, constructed as shown, and so arranged that it projects slightly beyond the face of the knife B, and extends across the face of the blades only far enough to take in the rib of the plate.
This arrangement and construction of the gage prevents parallel cuts from being taken when the turn-over apparatus is not started promptly, and it greatly facilitates turning over the plate.
or recess, 8, on its end. By this means we ing out while being carried down to the score in the bed-die.
The form of the ribs a may be varied considerably within the scope of our invention, as illustrated in Figs. 7 to 10; or'the ribs may be made on but one side of the plate, as in Fig. 11; or on the alternate opposite sides, as in Fig. 12. a barbed point is desired, to carry the out of the tang a short distance into the bead on that side of the plate instead of terminating it at the edge of the rib.
Having thus described our invention, what we claim as new, and. desire to secure by Letters Patent, is in a machine for cutting, in the usual manner from double-ribbed plates,
