SPECIFICATION forming part of Letters Patent No. 470,132, dated March 1, 1892. Application filed November 28, 1891. Serial No. 413,422. (No model) To all whom it may concern.-

Be it known that I, CHARLES E. HOUGHTON, a citizen of the United States of America, residing in Northumberland, in the county of Northumberland and State of Pennsylvania, have invented a new and useful Nail-Machine, of which the following is a specification.

My invention has relation to improvements in machines for cutting pointed nails from a rolled plate; and the object is to provide an efficient, simple, and improved mechanism for moving the point-cutting dies laterally, and I accomplish the object by the mechanism or its legal and mechanical equivalents illustrated in the accompanying drawings, Wherein Figure 1 is a plan View of a nail-machine having my improvements connected thereto, certain parts being removed for the purpose of better illustrating the improvements. Fig. 2 is a vertical section through the knife-bed of the machine, showing the arrangement of the die-moving bar or lever. Fig. 3 is a detail of the point-cutting bed-die. Fig. 4 is a detail of the liner of the point-cutting die. Fig. 5 is a detail of the cutting-jaw, showing the means for returning the dies to inward position or relation. Fig. 6 is a detail of the plate for returning the dies inward.

The present invention has for it primary object the production of mechanism of an improved construction for moving the pointcutting bed-die laterally, so that, in conjunction with the grip effected on the point or end of the nail-blank by the two point-cutting dies, a point may be made on the nail.

Referring to the drawings, wherein the same parts appearing in the different figures are designated by similar notations of reference, A designates the bed of the machine, B the gripping-lever, and C the heading-lever provided with a header a, as usual. The gripping-lever is formed with a die-seat 1, wherein the gripping-die 2 and point-cutting die 3 are secured. These elements are counterparts of those secured in the knife-bed at the front of the machine, except that they are secured ings.

.duce a lever or barin the bed of the machine at the front and to connect said lever to some moving part of the machine to give it the desired or requisite movement for effecting the purpose. In the present instance I provide the following described mechanism.

In the die and knife bed of the machine (designated by the letter D) is arranged the bed-gripping die 1, which is of the usual form and construction of those employed in machines of this character or construction. Adjacent to this gripping bed-die is the liner 5. This liner has extending from its side two studs or pins 6 7, the ends of which abut against the face of the wall of the knife-bed, as seen in Figs. 1 and 5 of the drawings, to afforda stay, against which the gripping beddie lodges when screwed up in place by the set-screw 8. In the forward under side portion of this liner is a recess 9, in which the lug of the operating bar or lever loosely projects, as hereinafter specified more fully.

E designates the point-cutting bed-die, having a proper point-cutting face and arranged in itsvseat or bed to have a limited lateral movement, as indicated in Fig. 1 of the draw- This point-cutting die E is formed or provided with two transversely arranged holes 10 11, which loosely take the pins 6 7 of the liner 5 to hold it against endwise displacement and keep it in a proper position and relation to the adjacent elements.

In the knife-bed below the dies is formeda hole 12, constituting a bed or seat for the lever or bar 13, and from this hole at the inner end thereof is an opening 14, extending through the floor of the bed, as indicated in Fig. 2 of the drawings. The lever 13 consists of a bar fitting the hole or seat, and at theinner end is provided with a lug or projection 15, which is arranged to project through the hole or opening 14 into the recess in the liner and bear against the inner face of the pointcutting bed-die. The outer end of the lever 13 projects beyond the face of the knife-bed, and is provided with an arm 16, which lies on the upper face of the heading-lever, as shown, so that when the heading-lever is moved upward the arm 16 is lifted and the bar turned to that extent which brings the lug 15 in engagement with the point-cutting beddie, which is thereby pushed outward at the instant when the point is being cut on the nail, thus imparting a shearing function to the contacting point-cutting dies. To return the point-cutting dies to a normal relation, a plate E is clamped adjacent to the moving knife, and having its lower end extending below the knife to engage both point-cutting dies, the inner edge face of the plate being inclined outward, as at 19, to the better engage the dies and gradually push them to their inward or normal position.

It will be perceived that the arm 16 of the bar or lever 13 may have connection to some other moving part of the machine than the heading-lever to lift it and turn the bar, my invention not being limited to the precise means shown for etfectin g the requisite movement of this element.

The operation is as follows: As the nailblank is cut from the plate and is pushed down by the moving knife into position to be engaged by the nipper and in order or succession by the dies and header it is held gripped, while the bar or lever 13 is turned to move the point-cutting bed die outward, which, being in frictional contact with the point-cutting moving die, also carries that implement outward after the cutting-j aw has moved upward and carried the projecting end of the plate E above the dies, thus leaving them free to be forced to make theoutward movement and cut and clean the point of the nail. After this has been accomplished the moving jaw makes the downward movement. The plate E engages the sides of the pointcutting dies and returns them to their inward position and relation.

Having thus specified my invention, as required by the statute, what I claim as my invention, and desire to secure by Letters Patent, is-

1. In a machine for cutting nails from a rolled plate, the combination of laterally-movable point-cutting dies and a plate E, arranged adjacent to and having its lower end extended below the end of the moving knife to engage the point-cutting dies and move them inward, substantially as described.

2. In a machine for cutting nails from a rolled plate, the combination of laterally-movable point-cutting dies, a rod or lever in the bed of the machine, formed with a lug to engage and move the point-cuttin g bed-die outward, and means connected to the said rod for operating it, substantially as described.

In a machine for cutting nails from a rolled plate, the combination, with a laterallymovable point-cutting bed-die and the headin g-lever, of a rod in the bed of the machine, having a limited rotary movement to move the die laterally, and a lever connected to the rod and engaging the heading-lever forimparting such rotation, substantially as described.

a. In a machine for cutting nails from a rolled plate, the combination of laterally-movable point-cutting dies, means, as specified, for moving the point-cutting bed-die outwardly, and a plate in the cutting-jaw of the machine to engage the point-cutting dies and move them inward, substantially as described.

5. In a machine for cutting nails from a rolled plate, the combination of laterally-movable point-cutting dies,a bar in the bed of the machine to engage the point-cutting bed-die, a lever to turn the bar, and a plate adjacent to the moving knife of the machine to move the dies inward, substantially as described.

6. In a machine for cutting nails, the combination of the liner 5, having the laterallyprojecting pins 6 7, and the point-cutting die formed with transversely-arranged holes to take the pins of the liner, substantially as described, and for the purposes specified.

7. In a machine for cutting nails from a rolled plate, the combination,with the die and knife-bed of the machine provided with a hole 12, extending under the knife-bed, and an opening 14 through the floor of the bed, of

.a rod 13, arranged in said hole and provided with a lug 15, projecting through the opening in the floor of the bed, a lever to impart a limited rotation to the said bar, and a pointcutting die in the bed of the machine arranged to have a limited'lateral movement, substantially as specified.

In witness whereof I have hereto set my hand in the presence of two attesting witnesses.
