NAIL-MAKING MACHINE.

SPECKFICA'IIOE'I forming part of Letters Patent N 0. 898,891, dated Itiarch 5,1889.

Application filed July 12, 1888.

To (ZZZ who/1t 7'; 'nm (Jo/accruilie it known that l. lQO UIs GODDL', of Winchester, county of Iiliddlesex, and State of Massachusetts, have invented an improve; ment in Nail-Making Machines, of which the following description, in connection with the accompanying (ilrawings, is a specification,

' like letters on the drawings representing like parts.

This invention has for its object the production of a machine for the manufacture of nails in a rapid manner and practically without waste of stock.

In accordance with my invention the wire fed into the machine is cutoff intermittingly in lengths equal to two nails, and the double blank so formed is offset at or between its ends where the points are to be formed, and 1 the offset blank is taken by the carrier, separated at the offset portion thereof, and thereafter each blank while held between die-rolls is subjected to the action of a header, which puts a head upon each nail, the nails so headed being thereafter discharged.

My invention in a machine for forming nails from wire-like material consists, essentially,

in the combination of the following instrumentalities, viz: feed mechanism to feed the wire, combined cutting and forming mechanism to sever the wire to form a double blank 1 and offset the same where the blank is to be separated to constitute the points for two nails, carrying-wheels for the blank, cutting mechanism to separate the double blank at its offset portion and form points for the nails, and heading mechanism to head the blanks, substantially as will be described.

Figure 1 is a front elevation of a machine embodying my invention; Fig. 2, a top or plan view; Fig. 3, a right-hand end elevation; Fig. 4, a vertical section in the line :11, Fig. 1. Fig. 5 represents the carrying-rolls H H separately.

The frame-work A, of suitable shape to sustain the working parts, has in it a main shaft, A, provided with several cams, as A A A and The framework has projecting from it suitable bearing-sleeves, as B B B B which receive in them the compound shafts B 3 and H. H, to be described, the shafts B B being provided at each end with like toothed gears, as B, the gears B being en- 1 gaged and rotated by like gears, B, 011 the shafts H H, the gears B being engaged by like gears, B upon a shaft, D. The shaft D has fast upon one end of it a ratchet-toothed wheel, D, which is engaged by a tooth, D of an elbow-lever, D pivoted at D, and having a roller or other stud, which enters a groove at one side of the cam A, the said cam, through the said clbow-lever and ratchetwheel, rotating the shaft D and the two shafts H H and B B".

The shafts H H and l3 1- at their inner ends have applied to them, respectively, the blank-feeding or carrier wheels H H. and C O. The wheels 0 and C are provided, re-

\ spcetively, with grooves a a and the wheels 3 H' H with grooves (L2 a the grooves a being,

however, slightly out of line horizontally with relation to the grooves a and the grooves a with relation to the groove a for a distance substantially equal to half the diameter of the wire, as best shown in Figs. 1 and 5, or to the l the movable cutter c, which as herein shown extent desired for the pointforming offset, yet the said grooves are substantially parallel. The blank-feeding or carrier Wheels H H are in like manner provided, respectively, with grooves a a slightly out of line, as described, of the wheels C.

In the open space between the wheels C C is a cutter-carrier, C (see Fig. 4 and in the space between the wheels 11 H is a like cutter-carrier, (1. Each of these cutter-carriers C C has its shank extended into a suitable guide, as (3 and each shank is toothed, as at O, to be engaged by segmental teeth (see Fig, l) cut into like rock-shafts, C one located above the rolls 0 O in bearings C, and the other being located below the rolls H H in suitable bearings, C The rock-shaft C has at each end a like arm, 6, which is connected by a like link, (2, with like arms, 0 secured to the rock-shaft C the said arms a each havirlg a roller or other stud, as 0 to enter a cam groove at the face of boththe cam-hubs A and A The said cams through the said. arms aiid links and rock-shafts eperate the cutter= carriers C C simultaneously to act upon and sever the double offset blanks I) (see Fig. 6) in the dotted line 00 the said severance being, it will be noticed, in the offset portion of the wire or metal comprising the blank.

The wire, 17, to be made into nails will be taken from a suitable feel (not shown) and be led between the feed-rollers d d, of usual construction. The feed-rolls d are connect-ed to a gear, (1 fast on a shaft, d in a box, d, and the feeding-roll d is fast to a toothed gear, d, in engagement with the toothed gear (1 The toothed gear 01 is fast on a shaft, d having a ratchet, (Z which is engaged by a spring-held pawl, d carried by a pawl-carrier, (Z (See Fig.9.) The hub of said carrier d is providedfor a portion of its periphcry with gear-like teeth 61, (see Fig.2,) which are engaged by the teeth 2 of a sector-lever, 61 fast upon a shaft, d? The said lever d? has a downwardly-extended arm, (P (see 1,) provided with a roller or other stud, whieh enters the cam-groove (Z in the camhub A the said lever actuating the feedingwheels interinittingly.

The wire at the rear side of the feedingwheels enters a wire-channel, 3, formed in a plate, e, (see Fig. 14,) covered by a cap, 6', the

plate e being provided with a cross-groove to said grooves. The cutter is provided with a in order that when the said cutter member becomes worn by the continuous passage of the wire through it the said cutter member may be cut off or shortened, so as to bring a new groove into operative position with relation to the wire-channel 3, and to co-operate with the cutter and former are operated. her 12* of the former as it rises co-operates receive in it the stationary cutter member a, shewn separately in Fig. 15 as composed of a bar having a series of grooves, in order that 1 the wire may readily pass into any one of the r is also a former.

Immediately opposite the carrier-wheels the plate 6 is slotted entirely through in the line of the channel 3 to receive within it a combined cutter and former, a attached by setscrews (2 to aformencarriage, e", (see Fig. -l,) having rack-teeth, as a, which are engaged by segmental teeth e of a lever, c having a roller or other stud which enters a groove in the right-hand side or face (see Fig. 10) of the cam-hub A The groove c (see Fig. i) at the opposite side of the said camhub A receives a roller or other stud at one end of a lever, c having its fulcrum at 0 (shown by dotted lines, Fig. 4,) and having an arm, a, to which is attached, by a screw, 0, in a slot, 0 the transferrer 0 (see Fig. 18,) the said transferrer having imparted to it a movement at right angles to that of the wire as produced by the feeding-wheels The forward'end of the transferrer e is bent in the direction of its width to correspond with the face of the formere (see Fig. 16) and to the shape given to the blank between the upper end of the said former and the anvil-like face at the under side of the cap 6. The inner end of the horizontally-moving transferrer c rests in a space corresponding in shape with it between the plate 2 and the cap 6', and it stands with its free end just outside the line of movement of the former a when the latter is raised to bend the blank, and the blank having been bent to conform longitudinally to the ends of both the said former and the said transferrer the transferrer is started forward and removes the said bent blank from the space between the plate 6 and cap e and pushes the blank laterally into the grooves a a of the wheels 11 H as will be further described; The cap 6, at its under side immediately above the bender a has an anvil-like face, (see Fig. 14,) (designated by 5 6,) the two faces being joined by an incline, 7. The transferrer is also of corresponding shape in cross-section, (see Fig. 18,) and the top or acting face of the former is of like shape-that is, it has a portion, 8, which is longer than the portion 9,. and the two portions are connected by a beveled portion, 10. g

After the wire has been fed into the groove 3 until its end meets the stop 12 (see Fig. 16)

The corwith the stationary cutter member 0, severs from the end of the wire a blank of a length sufficient for two nails, and at the same time that it severs the wire to form the blank'the former and the anvil above it act to offset the s'eriesof grooves, rather than with one groove, l

blank and leave it in the condition represented in Fig.6, where the offset blank is designated by the letter Z). The shaft 61 and the shaft f parallel to it,-(see Fig. 1,) both extended to the rear of the machine, have fastened to or made as part of them like sector-gears, f, (see Fig. 8,) which engage, re-

F. The die-roll F is fast upon the shaft D, while the die-roll F is fast upon the shaft F having its bearing in a detachable frame, Ffl'secured by bolts F to a strong The shaft F has secured to its opposite ends like gears, F which are engaged and rotated by the gears Bf, before described, the said gears F on the shaft F being kept firmly in equivalent contrivance, the said screw being herein shown as screwed into the frame, and having an enlarged head or collar to act upon part of the frame F.

The double blank, or a blank of sufiicient length for the formation of two nails point to point, after having been offset as described, is acted upon by the transferrer 0 It is moved forward from the line of the groove 3 and placed in the grooves a? a of the wheels H H the latter wheels being moved intermittingly in unison, so as to receive one double blank after another in its nearly-parallel 011' the machine. Should the said nails stick in the die-grooves of the die-rolls F, then the stripping-plate 68, attached to the block or frame F by the screw 69 and straddling the die-rolls, will remove the nails, making them fall from the machine into any suitable receptacle.

The part of the frame-work having the bearings for shafts B B bolted to a main upright, 71, of the frame-work by bolts 71, extended through holes in the frame a little and the rigid portion of the frame is provided with a headed bolt, 71*, which, acting against 1 the bearing portion, causes the gears to be engagement with the gears 13 on the shaft D by means of a strong screw, F, or other i i l tangent point of the two wheels C C on one side and the two wheels H H' on the I 64, until the separated blanks are delivered into the die-grooves of the rotating dieheld firmly in mesh with the gears 13.

Herein it will be noticed that the wire to be formed into nails is offset where the points of the nails are to be formed, thus enabling the wire to be cut practically at right angles to its center, and enabling the wire severed by a single cut to leave proper points for each nail, the offset portion of the nail when severed leaving the points beveled in two directions, with the apex of the point substantially at the center of the nail, the points being thus formed without waste of stock, and by merely olfsetiing or bending the double blank centrally and then cutting the blank the point of thenail is not hardened, but is left comparativcl y soft. The points are practically formed by a cutting rather than by a co1npressing operation.

The edges of the shields referred to under which the severed blanks travel have flanges opposite the head forming parts of the blanks to prevent the nails moving laterally out of the grooves in which they rest. The die-grooves at their outer ends may be round or of other shape, and be more or less enlarged to enable the metal of the blank when acted upon by the headers to be upset into the said space to give any desired form or shape to the head of the nail.

The inner ends of the grooves and the dierolls are shaped to conform to the shape desired for the points of the nails, and when the header operates to strike the nail to head it it also moves the nails slightly in the said die-groove, so that the point of the nail will I be finished.

at which time the headers described are opj erated. 'lheheaders act to head the two partially-formed nails while the said two rolls hold the said nails in their die-grooves. A

I do not claim, broadly, the formation of two nails at one operation, or the severance of a double blank to form two nails.
