' SPECIFICATION forming part of Letters Patent No. 478,054, dated June 28, 1892.
Application filed December 12, 1890' Serial No. 374,425- (No model.)
To all whom it may concern:
Beit known that I, LOUIS GODI U, of Vinchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Nail-Making Machines, of which the following description, in connection with the accompanying drawings, is a specification, like, letters and figures on the drawings represent-.
fed intermittingly to the machine by feeding devices shown as rolls, the said Wire being cut off to form blanks of a length sufficient for two nails, the blank, being offset or bent at or near its center, all substantially as in the said patent.
One part of my invention consists, essentially, in an organized machine for manufacturing nails, it comprehending sectional die- 0 rolls arranged in pairs, the grooves in the sections of each roll of the pair being out of line for the reception of a double blank offset between its ends, a transferrer to placeablank in the grooves of one of the said die-rolls,
point-forming dies or cutters to sever the blank through its offset portion, carriers for the said dies, and heading tools or devices cooperating with the said pair of rolls, whereby each nail is pointed and headed in its own groove; also, in the die-rolls and the carriers having the point-forming cutting-dies and meansto actuate the said carriers, combined with a nail-breaker to separate the nails in case the blank should not be fully severed by the point-forming dies, substantially as will be described.
Other features of my invention will be pointed out in the claims at the end of this specification.

Fig. 10 is an enlarged face view of one of the point-forming dies. Fig. 11 is a vertical section taken through both the upper, and lower dies in the dotted line 2, Figs. 10 and 0 12. Fig. 12 is a view of the dies shown in Fig. 11, looking from the right.
The frame-work A is and may be of -'any suitable shape to support the'working-parts.
The main or cam shaft A of the machine 5 has mounted upon it a series of cams B O D E and a toothed gear F, the said gear being en gaged byapinion F (see Figs. tand 5) upon asleeve F connected with the driven member F of the friction-pulley device, to be de- TOO scribed, the said member turning upon a stud F The driving member or portion F of the friction pulley, which receives the usual driving-belt, is mounted loosely upon the sleeve-hub F of the pulley member F before referred to. The stud F which receives upon it the hub F ,.is extended through a bearing-hub F, which is driven into a hole drilled for it in the frame-work, the outer end of the hub being turned externally and bored internally, the internal bore receiving the hub F while the externalportion receives upon it a lever E to be described. This stud at its outer end has fastened toit by a screw 20 (see Figs. 1, 4, and 5) a collar 21, having a cam-face, and between the said col lar and the end of the hub of the loose pulley is arranged a second cam-hub 22, (see Figs. 1 and 5,): provided with a toothed gear 23, the gear being shown by dotted lines in Fig. L. The gear 23 is engaged bya toothed sector 24, fast upon a starting and stopping rod E eX- tended, as shown, across the frame-work and provided with a handle 25, so that the operator may rotate the cam-collar and engage or disengage the friction-pulleys to start and stop the machine, as desired.
Instead of the particular friction-pulley device I may use any suitable known equivalent. The frame-workA is carried above the said shaft and has an extension A (see Fig. 2) located at or near the upper side of the lowermost die-roll, to be described, the said extension having pivoted upon it at A a leg or web A forming part of a head A the said head constituting a hinged or pivoted part of the frame-work.
The cam B receives a roller or other stud B, attached to an arm or bar B provided with rack-teeth B of suitable shape to engage a beveled pinion B (see'Figs. 1, 6, and 6%) fast on-the shaft B to which is secured the hub or plate B having studs, upon which are pivoted the pawls B which engage the teeth of and rotate a hub B loose upon the shaftB but having fast upon it the lowermost feed-roll B, which engages the wire 20 to be made into nails, the said feed-roll having bolted or fixed to it in suitable manner a gear B, which engages with a gear B (see Figs; 1', 3, and 7,)-to which is attached by suitable screws or otherwise secured the upper yoke receiving through itan adjusting-screw B which is screwed into a fixed part'of the frame, the-rotation of the said screw regulating the effective pressure of thepair of feed-rolls upon the wire being fed into the machine. The wire acted upon by the wirefeeding rolls, which are substantially the i' same as in said patent, will be fed forward into position between the formers or benders c and 0 (see Figs. 2 and 8) and may be cut off, as provided for therein and after this the bender 0 will be depressed or moved toward the bender c, which remains stationary.
Referring to Fig. 8, it will be seen that the I left-hand edge of the bender c in its vertical movement passes closely against the inner end of the guide n, through which the wire 10 is led, so that the bender in rising against the wire to bend it also acts asone member of a cutter, the other member being the end of the guide n next the bender.
Each former or bender (shown as a plate) ?'presents two acting faces located in different horizontal planes, the said faces being conv nected by an inclined portion, (see Fig. 8,) so ,that the metal blank clamped between the {acting faces of the benders is offset or bent substantially midway between its ends, the said metal blank when so offset being acted upon by a transferrer 0 (shown in section, Fig. 8, and in plan, on a smaller scale, Fig. 2%) which is suitably shaped at its edge to act upon the blank and push it out from between the bending devices into grooves of the dierolls, to be described.
The bending or offsetting devices and the transferring device are substantially the same as in my said patent; but herein they are {actuated by different mechanism, to be deiscribed as, for instance, the transferrer (shown best in Figs, 2 and 2) is secured to a reciprocating frame 0 mounted on a stand is, having at its under side a series of rackiteeth 0 which are engaged by a rack-bar to, connected to or forming part of a lever Sic and adapted to turn upon a pivot 0 the lsaid lever having a suitable roller or other lstud 0 (see Fig. 1,) which enters a camigroove at one side of the cam-wheel C. It is (essential that this transferrer be accurately placed upon the carriage or frame 0 and this I have done by means of screws e extended ithrough slots 0 in the transferrer; but to provide against smashing parts in case two Lfblanks or pieces of wire should happen to get gin front of the transferrer these screws are not set down so firmly but that the transferf re r may slip back on the carriage on the ocicurrence of such an accident. The lower lbender-plate c is adjustably held between a gli p of a vertically-movable carriage c and a cap-plate 0 secured thereto by set-screws c which are passed from the said cap-plate Zthrough slots in the said bender and are screwed into the said carriage.
, have provided an adjustable wedge c", which rests at its lower edge upon the said carriage, the upper beveled edge of the wedge acting against the lower beveled edge of the benderplate, adjustment of the wedge in the direction of the arrow thereon when the screws 0 j are loosened elevating the bender-plate.
The carriage 0 adapted to slide up and ldown in suitable guides or grooves made in To adjust the bender-platec vertically, I.
the frame-work, has a series of rack-teeth at 2, which to reciprocate the carriage are engaged by rack-teeth 3, attached toor forming part of a lever 61, (shown in section in Fig.2 and detached in Fig. 3%) the said lever having its fulcrum upon a rod or stud cl, fixed with relation to the frame-work. The lever (Z referred to is provided at its outer end (see Figs. 1, 2, and 3) with a cross-bar or roll-carrier (Z adjustablyconnected thereto, as will be described, bya set-screw (1 the said crossbar having at its opposite end suitable like rollers or other studs (1*, (see Figs. 2 and 3%) which enter like cam-grooves d in the faces of the hubs O and D, the shape of the grooves being shown in the hub D, Fig. 2.
The upper bender-plate c, which may be considered as the anvil on which the blahk is bent, remains in fixed position during the operation of offsetting the blank. The said bender-plate is held in position against a bedba'r e by means of a clamping-bar 6, held in place by set-screws e the said bed-bar hav-. ing attached to its inner side by screws e a shield or cover e to extend over the blanks contained in the grooves of the lower sec-- collar D or D surrounding a rotating shaft D or D, the said shafts each being provided with a shoulder D (see Fig. 1) and having a threaded hole at its end and extended through a like tube D within the bearing D, a screw to, extended through a washer 'u/ and screwed into the shaft, causing the washer to act on the tube D and clamp the two sections of the die-roll firmly between the tube and shoulder D, The outer face of the inner section of each die-roll abuts against the shoulder I), and between the two sections of each roll are placed, respectively, the collars D and D, the said collars surrounding the reduced portions of the shafts. The sections of each roll are so placed with relation to each other that the longitudinally-arranged peripheral blank-receiving grooves of one section are slightly out of line with relation to the blank-receiving grooves of the fellow sect-ion on the same shaft, the said grooves being so located out of line in order to adapt them for receiving blanks offset between their ends, as provided for in my said patent, the said blanks, properly fed into the grooves of one of the sectional die-rolls, being both pointed and headed therein, aswill be described, both operations being effected, as herein provided for, when the said blanks are brought into place to be engaged betweenthe lower and upper die-rolls. In my said patent the die-rolls having the grooves referred to arranged out of line were mounted onindependent shafts, each shaft having an attached gear, the sides of the die-rolls abutting against the die carriers; but in this present invention the sections making up the lower roll and the sections making up the upper roll are clamped on-the two shafts referred to and I am enabled to do away with a number of gears. The die-carriers G and G, to be described, are provided with elongated central openings (see Fig.2) to embrace the collars D D referred to. v
The head A referred to (see Figs. 1 and 2 carries the shaft Dfofthe upper die-roll, and the head when in the position in said figures must be held down so that the upper roll will be held in position to co-operate with the lower die-roll in holding the blanks.- To insure this result, the head A is provided with ears A having, preferably, stop-screws 120; These ears are engaged byloops A pivoted at A on the stands or lugs c of the frame-work, each of said loops having an adjusting-screw A to act on an car A when the loops are turned up, as in Figs. 1 and 2, and keep the head Aiwith the die 1'ollD in correct Workin g position with relation to the lower die-roll D, the stop-screw meeting the lower end of the slot in the loop and preventing the too great movement of the die-roll D toward the dieroll -D'.
e Provision has to be made for adjusting the bed-bar e horizontally, and to do this the The upper edge of the bender-bar c is acted upon by suitable positioning-screws said bar has been'provided with feet 6 (shown the said feet enter- (2 of the frame-work, (see Fig. 3,) so that the rotation of the said adjusting-screw moves the bed-bar longitudinally. The bedbar is held in adjusted position by means of the setscrews 6 and e extended through washers, which act upon the said feet, and by set-screws e and 6 The adjustment of the bed-bar horizontally enables the wire to be acted upon with more or less pressure at just the point where it is offset or bent.
, The horizontal portions of the benders' may 4 and preferably will be so set with relation to the diameter of the wire and the inclined portions connecting them as to produce less press ure upon the ends of the blank than upon that part of the blank which is to be ofiset or bent.
The journal D at one end ofthedie-roll D is extended (see dotted lines, Fig. 1) through the frame-worksufficiently far to receive upon it a toothed geauE and the ratchet wheel E (see Figs. l-a-ndt) and detent-wheel E, the teeth of the-ratchet-wheel E corre sponding, substantially, in number with'the grooves in the said die-roll.
The ratchetwheel E 1derives its step-by-step motion from apawl 3, mounted uponthe lever E pivoted on hub F", the said lever having a roller or other stud 4, which enters a cam-groove at one side of the toothed gear F, the said roll and the shape of the'said groove being shown in Fig. 4 by dotted lines. The lever E has an extension, which, is provided with a dog 26, which engages teeth of the detent-wheel E arranged at one side of the ratchet-wheel E the said dog acting as a detent to prevent any overmotion ofthe said wheel and dieroll due to momentum. The ratchet-wheel E is also acted upon by a friction-brake 27, which also tends to prevent any motion due solely to momentum.
In the patent referred to the offset blank was fed into grooves of two die-rolls and was cut through the offset portion thereof while held between said rolls and two other dierolls above them, and the separate nails were then fed into grooves in a third roll, and when brought opposite a fourth roll the said pieces of pointed wire were operated upon to form heads for the nails.
. In the present invention but one pair 0 rolls is used and the heading and pointing operations are both carried on in the same grooves into which the offset blanks are first fed, thus saving many parts and simplifying the machine.
The journals of the shaft D of the uppermost die-roll D rotate in bearings D forming part of the head A of the frame, and one of the said journals has fast upon it a toothed gear D (see Fig. 1,) which is engaged and rotated by the toothed gear E, fast on the shaft D of the lowermost die-roll, the said die-rolls rotating at .the same surface speed and in unison. Each die-roll is provided with a like number of horizontal grooves, into which are fed in succession the blanks cut off from the wire and offset, as described in my said patent; but I desire it to be understood that it is not essential that both rolls be of the same diameter or that they have exactly the same number of grooves, for one may have more or less grooves than the other and yet be rotated at the same surface speed, so that their grooves will properly match and form pockets to receive and hold the blanks. In the spaces between the two sections of each die-roll are placed the slotted carriers Gr G','which carry the point-forming dies 5 and 6, one of which dies is shown enlarged in Fig. 3 the said carriers fitting closely and accurately the said spaces, so as to obviate any possible lateral springing of the die-rolls or their journals during the heading operation. The carriers (see Fig. 2) are split to receive the dies 5 and (5, serrated at theirsides, as at 56, (see Fig. 3,) so that they may be engaged by a correspondin g surface of the carriers, screws 18 19 clamping the carriers on the said dies and holding them fixedly in place.
The point-forming dies are of a length to fit closely between the inner surfaces of the V die-roll sections, each point-forming die having two body-grooves 10 and 12 and two recesses 10 and 12, (see Fig. 3 where the recesses are shown enlarged, separated by athin cutting-edge 13,) the bottoms of the said recesses being shaped to correspond with onehalf of the point of the nailto be made.
The point-forming and wire-severing dies shown in the patent referred to were produced by cutting notches in the edges of the die-blocks bymeansof aV-shapedcutting-tool; but with such dies in use the body ofthe nail at or beyond thejunction of the point and body was liable to be bent or twisted out of shape, and to obviate this I increased the length of the die and provided the same with grooves in extension of the recesses, the said grooves receiving the body of the nail beyond its offset portion which was to be severed in the formation of points; but I found when forming the said dies by means of a V-shaped cutter that the latter left the recessed die in such shape that the cutting-edge 13 was not perfectly uniform in thickness, but was thinner at one point than another. In seeking to obviate this difficulty, as for practical work the cutting-edge must beof uniform thickness, I devised a cutting-tool having the inclined or beveled parts of its edge somewhat concaved, and by the use of such a tool I found that the body-receiving groove was left with a portion of its bottom convexed at opposite sides, but the pointreceiving grooves were by the tool brought to such uniform points that the thin cutting-edge 13 was left of uniform thickness. WVith this form ofdie cheaply made by the action of a tool the body of the blank is in no way distorted or bent or twisted or marred beyond the offset portion which is severed for the formation of the points. Fig. 10 shows one of these dies greatly enlarged, and Fig. 12 shows an end view of two of the dies brought together, wherein it will be seen that the portions '2" of the body-grooves are convexed, the body-grooves having small vertical walls r.
In Fig. 11 I have shown the dies in section, with a piece of wire placed between them,the wire being also shown by dotted lines in Fig. 12. Viewing Fig. 12 itwill be seen that the side walls and the central portions of the convexed parts support the body of the wire beyond the junction of the tapered point to be formed in the point-forming recesses and by the action of the edge-cutter 13. the shape of these recesses 10 and 12 the nails may be diamond, pyramidal, or other shape, as desired, the cutting operation being such, as described in my former patent, to separate the offset portion of the nail at nearlyright angles to the center line of the wire at that point, the cut so made serving to form parts of the points for two different nails.
The shanks of the carriers G G, guided in suitable ways in the frame-work, are provided at opposite sides, respectively, for part of their length with rack-teeth 14 15, (see Fig. 2,) the rack-teeth of the lowermost carrier being engaged by rack-teeth 16 at the inner end of the lever d, before referred to, the said le- By altering ver having pivoted to it a suitable adjustable connecting-rod f, attached at its upper end to a pin or rod f carried by arms f connected to a rock-shaft f having proper teeth 17, which engage the teeth of the upper carrier G, the said carriers in their operation having a slight backward movement, just enough to partially release the offset portion of the wire after'separatingthe same to form two points, this slight release taking place just before the heading operation.
The carriers G G are moved to and from each other in opposite directions to enable the dies carried by them to sever the blank at its offset portion just before the heading devices, to be described, operate upon the ends of the two nails formed by separating the blank. The adjustment of the cross-bar or roll-carrier (1 upon the lever (Z and the adjustment of the connecting-rod f enables the positions of the carriers when the point-forming dies or cutters act to sever the offset portion of the wire to be governed to a nicety, so as to enable each die to cut to the center of the wire, each doing its own part of the work.
The cam-hub E receives within it a roller or other stud 28, connected to a lever H. The lever H and the lever B are each at their inner ends connected with suitable vertical rock-shafts 30 and 31, provided, respectively, with toothed gears or plates H H which engage, respectively, the header-carriers H and 1-1, each provided with a like header 32, one or both, the said headers being made ad j ustable longitudinally in the said header-carriers by any usual or suitable devices, as a screw 33. (Shown in Fig. 5 as combined with header 32.)
The adjustment of the headers in the header-carriers provides for making heads of greater or less size and for adapting the headers to the wires of different diameter.
The frame-work of the machine is provided with gages 34, against which the ends of the oifset blanks strike if the said blanks are out of position in the die-rolls, thus placing the said blanks with their offset portions in ex actly the proper position to be acted upon by the point-forming dies or cutters before the said blank comes into position directly between the two die-rolls, so as to be separated,-
as it will be understood that the blanks are not clamped between the two die-rolls except when the points are to be cut and the heading is to be done. By disconnecting the link f, which passes through a hole f (see Figs; 2 and 3) in the transferrer'c from the pin f the head A may be turned over, removing the roll D from above the roll D. The-headers, acting upon the wire projecting slightly from the grooves in the die-rolls, act to head the nails.
In case the point-forming dies or cutters fail to completely sever the blank when makthe continued rotation of the die-rolls be car-V ried under the nose or shield 35, Figs. 2 and 3, and under the point-breaker 36, Fig. 2, (shown as a projection standing in the central space between the two grooved parts of the lower die-roll,) which acts on the nearly-severed blank and separates it, leaving two separate nails. The breaker is steadied and held to its work by a screw 40;
The lower die-roll of the machine has been provided with a stripper 37,(sce Figs. 2 and 9,) which stands partially in the central space of the said roll, to insure the discharge of-each nail .in case it for any reason should stick in the die-grooves. The stripper has at its righthand end a clearer 38", having an inclined edge, which acts against the end of any short pieces of Wire, pieces too short for two nails, and effects their discharge -from the said grooves. t
The gear E is shown as provided with a projection h, which is acted upon at its opposite sides by like set or adjusting screws 43,
(see Figs. 1 and 4,) inserted in hubs attached to the rear side of the wheel E adjustment of the said screws in orout enablingsaid'wheel E and the intermittingly-actuated ratchetwheel E both loose on the shaft D of the lowermost die-roll, to be adjusted thereon with relation to the gear E to correctly position the blank-receiving grooves not only with relation to each other and to the transferrer, but also to the headers. The machine described in the aforesaid patent contained six rolls; but in this my present invention I have succeeded by much study in dispensing with all but one pair of sectional rolls, the blanks being headed in the-same grooves into which they are fed from between the benders, thus greatly simplifying the machine, reducing the number of parts, and adding to its speed and efficiency of action.
' In the patent referred to the transferrer was attached to a lever and moved in the arc of a circle; but in the machine herein described the said transferrer is connected to a horizontallyreciprocating carriage movable in firm guideways, such construction being much more serviceable than in the patent re ferred to.
:as it is fed into the machine and preparatory gto entering the dies, and'to do this I have pro- }vided the machine, as shown at the left. in Fig. l and in Figs. 1, and 1 with an oiling idevice, shown as a cup 11, in which, as shown,
' The shipper-lever 25, herein shown. as fast on the rod E has a feeler or latch66, shown as pivoted thereon at (57, the said feeler be- ;ing notched, as shown at 68, to bear'on the wire and keep the shipper-lever in the position shown in Fig. 1 and the machine running; but when the said wirebreaks or runs It hasbeen found desirable to oil the wire Iout the said feeler, no longer supported by- :and turn the rodE and effectthe unclutch- ?the wire, permits'the shipper-lever to drop end of the lever '70 just below the feeler 66 toward the pivot 67. The opposite end of the lever 70 has a wire-guide '73, through which the wire w is led on its way to the feedingrolls and the bender. The wire in the formof a coil-or ball (see Fig. 1) stands on one end at one side of the post 71 on a suitable reel or-base, and as the wireleaves the coil or 1 receiving grooves are cut out at 104 (see Figs. 3 and 9) to leave a series of projections between them and the blank-receiving grooves of the rolls, which projections act as blades to cut off and break up any pieces of wire which become caughtbctween the die-rolls or any blanks which get out of place in the rotation of the rolls. have a clearer 38, like the one 38, co-operball .it hangs in spiral curves between the coil and lever 73, so that when the wire fails to be properly delivered from thecoil or becomes langled the extra strain put on the wire and acting on the lever 7 3 overcomes the stress of the spring '72 and turns the lever73 to act on the incline 69 of and lift the feeler (iliand effect the stopping of the machine. The transferrer c is provided (see Figs. 1 and 3) with a rest 100' for the inner end of a lever 101, fast onthe outer end of the eccentric stud B, on which the upper feed-roll B is mounted to rotate. The outer end of this lever 101 is extended under the feelerGG, and when the machine is working properly and but one blank is presented at a time in front of the transferrer the inner end of the lever -1s kept elevated; but should two wires or blanks get in front of the inwardly-moving transferrer thenthe transferrer in the inward movement of the carriage is arrested, while turn of the carriage to its outer position the rest is entirely removed from below the inner or right-hand end of the lever 101, so that that end, due to gravity or otherwise, descends, lifting its outer end and the feeler 66 to effect the stopping of the machine, and at the same time the partial rotation of the eccentric stud B lifts. the upper feed-roll sufficiently from the wire to prevent it from be-' ing fed toward the benders.
The carrier G at its front sidehas attached to it, as represented by a screw m, a directing-piece m. (Shown on a large scale in Fig.
2 and in section, on a much smaller scale, in
;the points as the offset wire is severed by the cutting-edge 13.
Fig, 2.) The Wire 10 emerges from a hole in a guide-block a just before it is caught by the feed-rolls, and after leaving the said rolls 1 rated and are engaged by the jaw-like lower it enters a hole in a second guide-block n, and the end of the wire leaving the block W. is to be fed into the space between the benderplates and transferrer opposite one set of grooves. During this operation to prevent the possibility of the leading end of the wire I striking against the inner side of the farthest I nails, it comprehending a pair of rotating die- 1 rolls having grooves out of line, substantially section of the die-roll D to the right I have provided a directing-piece m, i-t'lying partially in the space between the two sections of the said die-rolls and with its bevel face m in such position as to deflect the end of thewire outwardly into the space between the bender-plates. The top of the piece m is shaped to correspond with the offset part of the wire, so as not to interfere with the placing of the wire blank into the die-grooves.
This invention is not limited to the exact construction of the wire-oiling mechanism, nor to the exact construction of the shipperlever and the connections between the wire and'the friction-pulleys, nor to the exact construction of the feeler or latch 66 or of thelcver 70, as the said parts may be variously modified and other known equivalents used and yet come within the scope of. my inven- 3 tion.
The faces of the die-rolls between the blank- T he upper die-roll may ating with the lower die-roll.
In the machine described in the said patcut the rolls first to receive the offset blank were four in number, as each grooved roll had its own separate shaft, and the diecarriers between the sides of the said rolls were provided with cutters having a cutting-edge to sever the offset part of the wire, and at opposite sides the said cutter the said dies had only point-receiving recesses-that is, the recesses 1 in the dies were only long enough to receive lthe offset part of the blank.

j avoid the liability of bending the wire back In my experiments I discovered that to of the offset part to form the points as the wire was being severed a part of the body of :1 the wire must be held in the cutting-dies as jthe cutting-edge acts to sever the wire, and Qconsequently I have made the like cutting- ;f dies 5 and 6 (see the die 5, Fig. 3 broader, and besides the cutting-edge 13 and the point-receiving recesses 10 and 12, which may be as lin said patent, I have provided the grooves 1 1*0 and 12 to receive a portion of the main body of the blank each side thesaid pointreceiving recesses, the said grooves avoiding making bends in the body of the wire near The dies 5 and 6 have their outer sides ser ends of the die-carriers, which are split to form die-receiving jaws provided with suitable clamping-screws 18 19, by which the dies may be firmly clamped in place.
