- SEEOIFICATION forming part of Letters Patent No. 269,279, dated December 19, 1882,

Application filed June 10, 188-2. (No model.) A

To all whom it may concern:

Be it known that I, LOUIS GODDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Nail-Making Machines, of which the following description, in connection with the accompa-.

nying drawings, is a specification.

My invention has for its object the construction of a machine for the production of headed to and corrugated nails, chiefly for use for boots and shoes and leather-work.

In this my invention the blanks for the nails are cut from a metal strip and moved by a transferrer between the dies, where the body of the blank is corrugated and oneend is upset to form a head. The blank, as it is cut from the metal strip, is pressed down upon adirecting device made with a sharp edge to cutinto one side of or enter a groove in the blank, the said directing device holding the blank firmly between it and a flat or horizontal surface extended from one side of the upper die, in which theblankiscorrugatedand headed. Theblank is moved horizontally between the directing device and the said horizontal surface above it by means of the transferrer, which acts upon the rear side of the blank, near its ends, thus feeding the blank squarely into the space between the dies; but to prevent the blank being thrown beyond the center of the said dies I have provided a stop or blank-arresting device, which closes the gap at the farthest side of the open dies when theblank is entered between them. As the blank enters 5 the dies it is fed beyond the end of the directing device, which,pressed upward by a spring and having its end entered within a recess at the side of the lower die, is elevated so that the end of the directing device comes into position at the rear side of the blank, the end of the directing device and the forked end of the stop aligning the blank in the dies before or as the dies close upon the blank. The header is shaped to countersink the heads of the 5 nails. The groove formed in the side of the blank and entered by the directing device aids very materially in insuring the correct presentation of the single blanks between the dies to be corrugated and headed; but, if de sired, the strip may be creased at one side longitudinally before being fed into the machine, or may be partially creased or grooved in the machine as the strip is passed to the cutters to have a blank separated from it.

Figure 1 represents a front end elevation of the principal part of a nail-making machine embodying my invention. Fig.1 is a development of cam A Fig. 2, a partial rear side elevation of Fig. l Fig. 3, a partial top "iew broken out to show one of the operating-cams; Fig. 4, a section on the line a: 00, Fig. Fig. 5, a section on the line 00 Fig. 1; Fig.6, a detail of the bed upon which the strip rests, with the transferrer shown as acting upon the edge of a blank and as feeding it forward; 6; Fig. 7, a sectional detail in the dotted line 012 Fig. 2, showing the dies and the device for throwing the nails from the dies after thelat-.-, ter are opened; Fig. 8, an enlarged vertical section of the dies, showing the projections thereon for corrugating the body of the blank, and in which the head is upset.

Fig. 20 shows a pawl and ratchet for moving the feed- 5 ing-rollers. Fig. 21 is a broken detail of the pawl shown in Fig. 20, to illustrate the spring for holding it down upon the ratchet. Fig. 22 shows the under side of the strip as it will appear after passing the feed-rollers. Fig. 23 Ice shows a blank cut from the strip; Fig. 24, a nail made from the blank, and Fig. 25 an under side View of the upper die.

The frame-work A of the machine, of proper shape to contain the working parts, has suitable bearings for the main shaft A having upon it the cam-hubs A A A The beltwheel A is connected with the cam-hub A (see Fig. 3) by a screw-thread. The cam-groove a receives a roller or other stud, c of an arm, a of a three-armed lever, B, having its fulcrum on a rigid sleeve, B (see Fig. 7,) the said lever being held thereon bya nut, b. The ends of lever B have toothed sectors a a, which engage sector-gears b b on the rock'shafts b I), grooved parallel with their axes (see Fig. 4:) to receive the ball-like ends of like links b the opposite ball-like terminations of which engage grooves of like cross-section in the followers (J G, which carry the two dies 0 0, between which the blank is shaped into a nail.

The follower O has fitted to it the steel blade d, made adjustable by the screw d and nut d, the said blade serving as the movable member of the cutting mechanism for severing ablank, d, from the strip 61 the under member of the said strip-cutting mechanism being the upper corner of the end of the steel or hardened block d, which constitutes the bottom plate of the guideway for the strip, down upon which block the strip is pressed by the shoe or plate 0 and rod 6, held under greater or less pressure by the spring 6 made adjustable by the screw 0 (See Fig. 4.)

The follower (1 (see Figs. 4 and 9) has fitted to it the shankfof the directing device f, having a knife-like edge, and extended forward, (see Fig. 15,) with its front end in a notch made in the side of the lower die, 0 at its face. This directing device is normally held up by a spiral spring,f on its shank, so that when the followers O O are moved to separate the dies 0 c the upper edge of the directing device will strike againstthe end of the strip projected beyond the end of the block (1 The dies 0 c are fastened to the followers by suitable screws, g g, and caps 9. (See Figs. 10, 11.) A block, f, on the shank f, entered within a slot in the follower C, keeps the directing device f in proper line.

The groove in the cam-hub A receives a roller-stud, h, on an arm, h, of a rook-shaft, h", having a second arm, 7L connected (see Fig. 3) by screw or pin iv with the link h having a eircularend, (see Figs. 1 and 12,) by which to attach it to the lower end of the lever h, which carries the heading device D. The lever h is attached by screw or bolt h with the yoke k adjnstably pivoted upon the frame-work by the screws h so as to adjust the lever and insure the correct entrance of the header into the open space between the dies 0 0 The header has its front end shaped to indent or countersink the head of the blank as the latter is headed and upset in the die-space 2. (See Fig. 15.) The shank of the header is extended into the nipple D against the abutting-screw D, and the nipple, screw-threaded externally, (see Figs. 12 and 14,) is screwed into an opening between an ear on lever h and the block I)", held in place by a screw, D The screw D arrests the backward movement of the header in the nipple, and if the header breaks or a new one is to be employed the nipple may be removed, and then the screw D and the header may be driven out. in the direction of the arrow in Fig. 14 and a new one supplied.

The cam-hub A* has at its opposite faces two cam-grooves, 2' i the one 2' being shown in full lines, Fig. 5, and the one i in dotted lines, Fig; 4. The cam-groove receives a roller or other stud, i (see dotted lines, Fig. 4,) of a lever, 13*, having at its upper end a pin, i (see Figs. 3 and 20,) which enters a notch in the arm t connected by pin 2' with the pawlcarrier 11, loose on the hub of the ratchet m, secured to the shaft on, having the lower feedroller, m. The pawl-carrier t is held upon the hub of the ratchet by the washer m and screw. The pawl 4 is held in engagement with the ratchet-wheel m by the spring 5, placed in a recess in the arm if. The opposite end of shaft m has a pinion, m which engages a pinion, m of like size on the shaft on of the upper feedroller, on, so that the pawl and ratchet move the feed-rollers, properly milled or fluted, so that they, in operation, will act to move forward intermittingly the strip (1 which will be placed between them.

The block 61, forming the lower member of the strip-cutting device, and also the bottom plate of the guide, has two longitudinal passages made through it from end to end for the reception of the transferrer a, composed of two wires heldin a block,6, pivoted between pointed screws a, (see Fig. 3,) at the upper end of the lever n pivoted at 01 (see Fig. 5,) and having a roller or other stud which enters the camgroove t, before referred to. The wires of the transferrer are stiffened and kept true by a block, 7, applied to them. \Vhen it is desired to stop the feed the arm '1' is lifted from the pin i of lever i.

The stopp, to arrest the block at the farthest side of the dies 0 0 is notched vertically at its front end, as at 10, (seeFig. 16,) and is connected by the screw 1) with the slide-rod p, actuated in one direction positively by the arm 19 connected with the rock-shaftp surrounded by a spiral spring, 12 the other end of the said rock-shaft having attached to it a second arm, 19 which, when the dies 0 c are fully opened, rests on the adjustable lug p attached to the sectorgear b fast on the rock-shaft b. The spring 19 when free to act, moves the rod 12 and stopp forward, so that the inclined upper and lower sides of the said stop (see Fig. 17) meet the inclined edges at the rear sides of the dies, the beveled surfaces of the stop and dies being such with relation to each other that the front end of the stop will be arrested at the rear of the die-grooves. As the dies 0 a are closed together the stop is gradually pulled back by the lug p acting on arm 10 The nail, having been finished, is thrown from between the dies 0 c by the ejector 0', (see Fig. 7,) made as a rod having a collar, r, acted upon by a spiral spring, r abutted against a threaded nut, 0 The outer end of the ejector has screwed upon it a long tubularcheck-nut, r adapted to reciprocate in aguide, 7, secured to the block 1", attached to the bracket 1'. The ejector has adjustably connected with it a collar, r having an annular groove, which receives the forked end of a lever, r pivoted at 1' and having a loose or swiveling block, 1', which is acted upon by the side cam. r, attached to belt-pulley A". The cam W has one end inclined, as at 12, Fig. 3; but its opposite end has at 10, Fig.2, an abrupt shoulder, from which the block 0' drops when the dies 0 e are opened, and the ejector is to be operated by spring 0' to throw the headed nail out from between the dies.

The upper side of block d may have a cutting-rib, 14, to enter and assist in making a groove in the strip to be entered by the directing device as the blank is cut 011'.

The die 0 has a horizontal extension, 15,

(see Fig. 25,)against which the upper side of the blank d maybe pressed, and the horizontal extension will be provided with a recess to prevent dulling the edge of the directing device when the latter meets the said die. The strip to be cut into blanks and made into nails will be passed between the shoe or plate and the block 61 and will be fed forward for the proper distance by the feed-rollers, when thelatter will be stopped,leaving the strip projected beyond the end of the block, the followers anddies c 0 being then fully opened. The followers will then be moved toward each other. The cutter member at will descend on the upper side of the strip and sever the same transversely close to the front end of the block 61", which is the lower cutter member.

The directing device is held up by springf against the blank, and as the blank is severed from the strip the cutter d, continuing to descend, presses the blank 61 down upon the sharp or thin upper edge of the directing device. The blank is depressed sufficientl y to place its rear side opposite the ends of the two wires forming the blank-transferrer, and the latteris then movedforward, pushing the blank before it, while the blank is held between the sharp edge of the directing device and the horizontalextensionl5oftheupperdie. During this movement the dies 0 c are sufficiently far apart to receive between them the blank d, and the rear side of the space between the dies is closed by the stop 1). As the transferrer pushes the blank beyond the endof the directing device f, the latter, acted upon byits spring, is thrown up behind the blank, and the latter is then held near the center .of its length by the end of the directing device, while the opposite side of the blank rests against the forked end of the stop 1). While so held the dies close together upon the blank, inclosing the body of the blank between the said dies, which, by their corrugated surfaces, corrugated the said blank for the shank of the nail to be produced. The

dies having closed upon the blank, the header D is thrown forward to upset or head the blank in the space 2 of the dies. The head having been formed and thedies having been partially opened, the ejectoris thrown forward toremove the nail from between the dies 0 0".

To insure the discharge of the nail in the proper direction, I have provided an inclined plate, 8, on an arm, 8, placed on the shaft k it having a spring, 8 by which to keep the plate .9 down in place. A nail striking the inclined under side of plate 8 will be deflected dowp into a chute or box (not shown) between itand the floor on which the machine will stand.

The face-plates t t, held by screws t keep the followers 0 c in their guideways. The strip (1 is omitted from Figs. 3, 4, and 5, but is shown in Fig. 9.

The adjustment ot'the collar r on the ejector enables me to cause the same to be projected forward just the proper distance to meet the point of the nailthen between the dies and to be removed, the said nails being of greater or less length, projecting more or less back of the die.
