To all whom it may concern:
Be it known that we, ERNEST WALTON and FREDERICK W. theme, of Kokomo, Howard county, Indiana, have invented certain new and useful Improvements in N ail-Making Machines; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.
This invention is an improvement in nail making machines, and .is a novel machine especiall designed for making roofin nails arge sheet metal heads an wire The object of the invention is to provide a machine whereby the wire from which the shanks are formed, and the strap-metal from which the heads are formed, are fed forward on intersecting lines, and, preferably, in its operation a proper length of wire is fed toward the operating point and clamped by suitable dies; and a proper length of strapmetal is fed toward the operating point and stopped; then a disk or nail head is punched from the strap and simultaneously-forced onto the end of the wire, the wire punching the head; then the head is preferably concavo-convexed by a further movement of the dies; then the shank is riveted to the- 1161 by means of a header-rod which preferably operates through the male punching die. Then the heading and unching dies are retracted and the wire, wit the attached head, is again fed forward the length of a nail; then the complete nail is severed from the wire by means of cutting dies, which preferably are also pointing dies. The feeding forward of the wire with the attached head, is merely a repetition of the first mentioned step of feeding the wire; and when the nail is severed from the wire, the end of such wire is in position to have another head attached thereto. The wire is clamped after each nail is severed therefrom and remains clamped until another head has been attached thereto as described. Thus at each operation of the machine a nail-head may be blanked from the strap metal, forced onto the end of the wire, and concavo-convex'ed, and the wire is swaged thereto; then the ir is f d forward a i e gth, nd a comp te n s se re he efr is cycle o operati ns s complet for ach op r tion view of the machine.
'vertical sectional view on line of the machine, and preferably for each ro tation of the main shaft thereof. 1
The invention will be more clearlyunderstood from the following description of the machine illustrated in the accompanying drawings which represent a ractical em bodiment of the invention an the essential features thereof, and the construction and combination of parts constituting the invention and for which protection is desired herein, are set forth in the appended claims.
In said drawingsFigure 1 is a top plan Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an enlarged plan view of the die-portions of the machme, with the strap feeding devices removed-and the dies opened. Fig. 4 is a horizontal section through Fig. 4, with the dies closed. Fig. 5 is a transverse vertical section on line 5'5, Fig. 3. Fig. 6 is a transverse section on line 6-6, Fig. 1. Fig. 7 is a view similar to Fig. 4 showing the position of the parts previous to the nail being headed. Fig. 8 is a detail 8-8 Fig. 5. Fig. 9 is a detail sectional view on line 99, Fig. 8. Fig. 10 is a detail view of the wire clamping dies. Fig. 11 is a perspective view of a complete roofing nail. Fig. 12 is a side elevation of the drive side of the machine. Fig. 13 is a bottom plan view partly broken away; and Fig. 14 is a plan view of the strap feeding device.
The wire w is led from a reel or coil (not shown) and fed by suitable meansv to the clamping die, which is preferably composed of similar opposite parts 1, 1, (see Figs. 3, 4, and 10); cac part 1 has a wire guiding channel 1 adapted to firmly bite the wire 10 when the die is closed thereon. The opposite parts 1 of the clamping die are respectively operated by means of a push-pin 2 inter- Pos d b t een the b o k a d short arm f a ev r pi o ed to a pi attac d o the p of th s n f m an the l ng arm f lever carr es a ol r 2 hi h ease as a attached; t9 th ma n ha t S;
is suitably journaled in bearings F on the top of the main frame. The roller 2 may be held in contact with the cam 2 b means of a spring 2 as shown in Fig. -1, suc spring tending to move the lever and cause block 2 to separate from block 2 and open die 1. The block 2 ma be connected to the lever 2 by alink 2 0 any suitable kind, so that it will be drawn away from block 2-, and open die 1, when the lever 2 is moved by spring 2 A bolt 2 may be tapped through the lever 2 andengage pin 2, so as to regulate and adjust the amount and time of pressure exerted by cam 2 upon the dies through lever 2. The block 2 may be adjustably mounted in a holder casting 2 securely attached to a projection F on top of the main frame; said block 2 being secured in position by bolts 2 2. The block 2 preferably has a dove-tailed groove-and-slot connection with the holder 2 as shown.
The parts 1, of the wire clamping die, also form 1n the example shown, the female mem er of the blanking die for cutting the nail-heads out of the metal strap .9. As
shown in Figs. 3, 4, 7, 10, the forward end of parts 1, 1, are provided with opposite semicircular recesses 1 1 which when the die is closed form a circular chamber or die, concentric to the wire groove 1 (see Figs. 4, 7 and 10) and preferably the bottoms of the recesses 1 1 areconvexed as shown at 1, for a purpose hereinafter described.
3 designates a male blanking die which is adapted to cooperate with the female blanking die 1 in the ends of clamping die 1 and out a circular nail head from the metal strap 8 which is fed between the dies 1 and 3 and aeross the line of the wire feed by suitable means as hereafter explained. This male blanking die 3 is removabl fastened to a slide 3 which is guided in al ox F attached to the top of the main frame, and said slide has an extension 3 which is attached to an eccentric box 3 inclosing an eccentric or crank 3 on shaft S, so that for each rotation 3f shaft S the die 3 is moved to and from the Arranged within the die 3 is a header-rod 4, which is adapted to operate through an axial bore in the die 3 and slide 3 and is connected to a slide 4*, guided in a box F on the frame, and connected to an eccentric-box 4 inclosmg a crank 4f on shaft S.
Located in front of the blocks 2, 2, are cutting and pointing dies 5, which are preferably detachably secured in recesses in blocks 5 adjustably secured to arms 5 pivotall mounted on rods f attached to brac ets f"'depending from the mainframe. These arms 5 may have depending ortions 5 against which press springs 5" w ch are so arranged as to tend to rock the arms 5' and normally se arate the cuttin dies 5.
As shown in igs. 5, 8 and 9, t e cutting fastened where adjusted by die' 5 is secured in block 5, by tap-bolts 5"; The block 5 is adjustable vertically on arms 5,- by means of a setting bolt 5, and can be means of a threaded shank 5' and nut 5 hese various adjustments providing means for adjusting the cutting and pointing dies 5 accurately.
The cutting dies are moved inward toward the wire at the proper time by means of levers 5 which may be pivoted at 5 on top of the main frame, and have bolts 5 tapped through their short arms engaging the blocks 5 as shown in Figs. 1 and 3. The long arms of said levers 5 carry rollers 5 engaging grooved cams 5 fastened on shaft S as shown.
The wire '11; may be fed forward to dies 1 by any suitable means. As shown, it is first passed through a straightener W, of any suitable construction, attached to one end of the main frame, and then led between a fixed jaw 6 and a pivoted jaw 6 attached to a slide 6, the jaw 63* being actuated by a spring 6 and adapted to bite the wire when the slide 6 moves inward toward the dies and to slip on the wire when the die moves away from the dies. The slide 6 is supported by a rod 6 guided in bracket F attached to the main frame and to one end of slide 6 is pivoted a rod 6 connected to one end of an oscillating lever 6 which is pivoted on a bolt 6 on the main frame, and the other end of lever 6 is connected by a rod 6 to a pin 6 adjustably secured to a block 6 fastened on shaft S. The connection between rod 6 and lever 6 is preferably an adjustable one, as indicated at 6, so that the throw of the slide 6 can be varied according to the length of wire it is desired to feed into the machine at each operation. The length of wire fed determining the length of the nail shanks.
The strap 8 may be fed vertically downward between the dies 1 and 3 by means of rollers 7 on shafts 7 journaled in a bracket F mounted on top of bracket F, the said shafts 7 have intermeshing gears 7 and on one of said shafts is a ratchet 7 which is engaged by a pawl 7 ivoted to lever 7 loosely mounted on suc shaft 7 and oscillated thereon by means of a link 7 attached to an eccentric strap 7 and surrounding an eccentric 7 on shaft S. The strap 8 is led in from a reel (not shown) through a suitable guide to the rolls 7. As shown it is passed through a guide slot 7 in a bar 7 m attached to casting F above the rolls, said slot having a spring actuated presser late 7 1 at one end, which tends to keep t 1e strap properly alined against the opposite end of the slot.
Preferably the wire is roughened or barbed so as to cause the nail to take a better hold in the wood. This may be accomplished in any way desired, as by milled feed rolls. As shown 1n Fig. 4, the wire grooves 1 in the parts 1 of the wire clamping die may be circular disk or ridged'u at1'1;-so that when closed u wire the "will roughen the'same as 'eatei- The aft Sma be .driven1in any suitable manner, and each revolutionthereof: the machine goes through a cycle-ofopera-- tions and produces a complete nail. The cams and eccentrics are'so adjusted on shaft S that the parts all operate in proper time and sequence, and the operation is briefly as follows: Assuming that the wire to hasbeen properly fed forward through the clamp-' ing die 1, its end rojecting into the recess 1' as indicated in F while the strap 8 has been fed down until its end .lies between the dies 3 and 1, die 3 being in retracted position, the die 1 is then closed upon the wire by the cooperation of cam 2 and lever 2, and while the wire is thus clamped the slide 6 moves backward preparatory to again feeding the wire. While the wire is thus clamped by die 1, the blanking die 3 moves forward and catches the metal strap 8, (which has been previously fed down between the dies 3 and 1, see Fig. 3), and punches a preferably nail-head H from this strap and forces said head into the female blanking die l andagainst the projecting end of the wire, causing the latter to erforate the head; and after the blank is orced upon the wire (see Fig. 7) the head is preferably concavoconvexod by compression between the convex bottom 1 of die 1 and the concave face of die 3 (see Figs. 4 and 7). Then' while the head H is tightly held between the dies 1 and 3 and the wire tightly held by the clam ing die, the header-rod 4, which has been fo lowing up the die 3, comes into contact with the end-of the wire projecting through the head andswages the same to the head as shown ath in Fig. 4. The parts of the clamping die are preferably slightly recessed-around the inner ends of grooves 1*, as shown at=1 in Figs. 4-7, so that a portion of the metal of the wire will be forced back and swaged against the inner side of the head, as shown at h in Fig. 4, and thus the head is united to the wire shank in a erfectly rigid and secure manner. The header-rod 4 then retreats, being followed up by die 3, and the block 2 is moved so as to open the clam ing die and release the wire; whereupon t e' wire is fed forward so as to push the completed head and attached part of the wire, out of the blanking die or recess 1 a distance equal to the desired length of the shank of the nail. Then, while the die 3 and header-rod 4 are retracted (see Fig. 3), the cutting and pointing dies 5 are caused to move inward and sever a nail len th, with the head attached, from the wire. The severed and com leted nail drops out of the way before the die 3 again brings" the stra 8 against die 1. The strap feed is operate in proper time to feed in a sufficient the} igs. 3-7, and that mean-- lengflt-of' strap to enablea=newhead to be melted-therefrom at' themext -operation ot? iesili The block 2 is'then'again moved' cause the clamping die to 1 clamp -tl'1e"wirje;
and the cycle 4 of: operations is repeated. Thus far and during each rotation of shaft S a complete nail as s own in Fig. 11',- is formed 1n the manner described.-
