SPECIFICATION forming part of Letters Patent No. 319,587, dated June 9, 1385.

Application mea July is, Issa. (No model.) Y

To all whom t may concern: Y

Beit known that I, WILLIAM KOPLIN, of Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Spike-Machines; and I do hereby declarethat the -following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention' relates to automatic machines for forming spikes from hot blanks, and concerns nearly all the mechanisms necessary or usually found in such machines for performing the several operations of feeding in the blank-rod, cutting OH the blank,

: straightening the shank, pointing and heading the spike, and discharging the spike from the dies and machine.

The novel features of construction upon which I make claim for invention will be fully vexplained in the course of the following de# scription, and will be more particularly designated in the appended claims.

In the accompanying drawings, Figure l is a side elevation of a spike-making machine containing my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section in the plane of the indirect line w x of Fig.v 2. Fig. 4 is a vertical section in the plane of y y, Fig. 3. Fig. 4 is a plan view of the front end of the machine with the pointingdie lever and the cutter-lever removed. Fig. 4b is a perspective View of the traveler detached, together with a part of the cam-shaft by which it is actuated. Fig. 4 is a fragmentary-perspective view showing a part of the traveler and of the cam-shaft, particularly showing the arrangement of the cam by which the traveler is retreated. Fig. 4d is a transverse section. of the cam-shaft detached, showing the two cams by which the traveler is actuated. -'Figs.

elevation of the matters shown in Fig. 8. Fig. l() is a perspective view of a detached guide for the feeding mechanism. Figs. 1l4 1 and 12 are respectively a plan view and asideM 5 5 elevation of certain details. Fig. 13 is a section of the cam-shaft, showing the relative positions of the several cams thereon.. Figs. 14. and l5 are side' views or elevations of particu-V lar cams on said shaft. Fig. 16 is a detached 6o end view of the heading-die, its outer end being presented to the eye. Fig. 17 is a detached side view of said heading-die. Fig. 18

is an inner end view of said heading-die, showing the recess therein for shaping the upper orouter surface of the spike-head.

A is a suitablystrong machine-bed appropriately mounted upon legs and having cast hereon journal-bearings A,in which is mounted the driving or cam shaft B, the latter be- 7o ing held in place by the caps b, secured in a familiar manner and provided with oil-cups b.

In the bed A are provided two openings,

A2 and A3, the former for the better accommodation of the cams on the shaft B, and the latter to aiford space for the iinished spike to drop from the dies and to give room for depending parts attached to the traveler, to which further reference will be made. l

C C are uprights located nearly centrally of 8O the machine, intended to afford support for the fulcrnms` of the pointing-die lever D and the cutter-lev`er E, arranged one above the other between said nprights. Said levers D and E are constructed, asV here shown, each of 8 5 a continuous casting having lateral proj cc-Y- tions or hubs D E', of length nearly equal to,

but preferably a little less than, the distance between the inner and parallel faces of the up- '.rights G. The ends of the said hubs DE are 9o Vc'ountersunk to receive the tapered points of the center pins, d e, which pass inwardly through the uprights C and enter the recesses in the ends of the hubs D E. Said center pins are illustrated as being constructed with 9 5 laterally-projectingheads dc,eXterior to the uprights C, through which pass the adjustingj screws d2 ci, entering the uprights, all as plainly indicated. in Figs. l, 2, and 4. The construction described allows slight but all neceso sary lateral adjustment of the levers to bring them into proper alignment with co-operating parts, and also for tightening the center pins to compensate the wear thereon. The lever D extends forward yfrom the middle point of the hub D,gand centrally of the machine, and terminates in a head, D2, recessed to receive the movable pointing-dies 112, to which further reference will be made.` At the rear of the head D2 said lever is cut away on its'un'der side to afford room for inserting the forwardlydirected clamping-screws 3, for holding said dies, as indicated in Fig. 3 and by dotted lines in Fig. 2. Said lever D extends rearwardly over the cam-shaft B at one side of the median line of the machine, or in the direction or position indicated more plainly in Fig.

2. The lever E passes forward from the hub F/ at one side of the lever D, and at its front end is provided .with a laterally-projecting head, E2, which stands in front of the head D2,

and is constructed to admit the knife or cutter E2, together with the adjusting-screw e and clamping-screw c2, as better illustrated in Fig. 3, lsaid knife being arranged in the same central line with the movable dies 112, located in the head D2. The rear end of the lever E extends backward over the cam-shaft andis deflected in a direction opposite to the deflection of the lever D, as shownin Fig. 2. At the rear extremity of each of the levers D andE is pivotally connected therewith a rod,as e3, Fig. 3, which rpasses through an apertured lug, a, yxed to the machine-bed A. Beneath this lug a spring,

as e5, surrounds the rod,`said spring being confined by a nut, as e4, applied to the threaded extremity of the rod e3. By means of these rods and springs the rear ends of the levers D and E are held down upon cams affixed to the shaft D for the vibration of said levers, so that the heads D2 and E2 of said levers are raised when the cams are in position to permit this movement.

I is a stationary pointing-die secured beneath the movable pointing-dies I and I2 in a suitable recess in the angle-shapedcasting J, which casting is fastened to the machine-bed Aat the rear margin of the opening A3 by means of suitable bolts, j, as shown in Fig. 3.

H is a stationary headingdie arranged horizontally opposite the stationary pointing-die I, and secured in an appropriate recess in the lelevated part A4 of the machine-bed A' over the'front margin of the opening A3. The die H also serves as a stationary knife or cutter, acting in opposition to the vertically-reciprocating cutter E3, the edge of which passesin its downward motion close to the inner vertical face of said die H. I

F is a traveler arranged to slide upon the machine-bed A, and consists of a frame having a central oblong opening, by which it surrounds the dies H and I and their immediate supports, as shown in Figs. 1, 2, 3, 4, and 4"'. Said traveler F is provided with lateral projectionsf, fitted t'o slide beneath the guides f', which are rigidly'attached to the bed A, and by which the traveler is held laterally in place.

At its rear end said traveler F is also `provided with an arm, F, constructed to form the yoke F3, embracing the shaftB and a cam thereon for carrying forward the traveler. As seen in Figs. 2 and 4c, said yoke is provided with a lateral projection, F2, on its rear vertical portion, which engages another camon the shaft B, by which the traveler isretreated. Back of the cam-shaft B the yoke-arm F is fitted to slide between guides f', which serve to hold the arm in place with reference to the cams.

Referring next to Figs. 4 and 6, F5 is a die secured in a recess of the traveler F by suitable clamping and adjusting screws, and constructed with a projection, f5, which is intended to support the blank on its lower surface for, say, an inch or more near the proposed head, or at T, Fig. 7, while theadjacent vertical and rearwardly-extended face of said die supports the blank on one lateral surface throughoutthe whole or a quarter ofits length.

F6 is an opposing die similarly secured in a laterally andV upwardly movable frame or diesupport, F2, which also moves with the traveler F; and said die F6 is provided with a prof jection, f2, which bears upon the upper surface of the blank opposite the projection f5, while the adjacent vertical and rearwardlyextended face of the die bears against the side of the blank in opposition to the die F5. These dies are preferably constructed in L form, as better shown in Fig. 6, so as to bear upon the sides of that part of the blank which is to formv the spike-shank throughout its entire length, and to thus insure its straightness. 'f

The projections f5 and f6, with the adjacent bearing-faces of the dies, form an orifice, f2, by which, when the dies are brought together,

the blank is entirely embraced in that portion vthereof which is to form the shank of the spike near the head. The front faces of .said dies are recessed or cut away about the orifice f2,

as plainly indicated in Fig. 6, in order to give proper shape to the under surface of the spikehead. The dies F5 and Fhavingamovement with and by means of the traveler F, the pro^- IIO jections f5 and f are narrower than the space w between the dies I and H, and in practice are made to nearly o1' quite touch the die I-when the traveler is retreated and to proximate the die H whenthe traveler is'advanccd. i

In addition to its bodily-movement, derived from the traveler, as described,the die Fs has a reciprocating movement in alateral and up- IBO wardly-inclined direction, or in the direction,

substantially, of the diagonal of the orifice f 2. For this purpose the following devices are here provided: F4 F2, Figs. l land 4, are two depending and laterally-projecting arms belonging to the traveler F, between which is an open vpassageor space longer from front to rear than the length of a finished spike, in order to let the spike fallwhen completed and released yfromthe dies. Within this space is arranged the die-support F2, for the immediate support of lthe movable die F6, and said die-support is provided with a downwardly-directed arm, FB, projecting in the directionof and between the arms F, and pivoted to them at their lower endsby the pivot-boltfz.` The die-support F7 is whollyto theleft of a vertical plane drawn through the axis f 2, so that when said die-support-F7 and the die FG carried thereby are pushed away from the adjacent die Ff they are also raised in a direction practically that of a diagonal line drawn through the orifice f7.

As an appropriate means for pushing the arm F8 outward, and thereby elevating the die F6 in the oblique direction above indicated, a stout rod, FF", is pivoted to the arm Fs below the bed of the machine, .having itslfree endl supportedby being passed loosely through an aperture in a stationary bracket, f8. A nut, f3, or equivalent device, is applied to the rod F` between the bracket and the arm F8, and between said nut and said bracket f8 is arranged an expanding coiled spring, f4, which operates through the rod to throw the arm FB to the right andb thereby lift and retreat the dieF. Said die is thrown in the opposite direction, or downwardly and inwardly toward the stationary opposing die F5, by means best shown in Figs. 1, 2, 4, and 4, consisting of a reciprocating bar, G, provided with the wedgeshaped head g2, said bar being supported on its outer or straight side by a portion of the traveler F, and bearing on its inner or inclined side against a roller or projection, F", on the adjacent side of the die-support F7. Said bar VG is connected with a slide, G', which extends beneath the shaft B, and is fitted in guidewaysg. From said slide G, on either side of the rotating shaft B, rise the vertical arms g, which embrace a properly-shaped cam upon said shaft. By the action of this cam upon the arms g the slide G and.wedgebar G are carried backward toward the rear end of the machine, and at the same time, as will further appear, the traveler F advances toward the front of the machine. In this relative movement of the parts named the wedge-face g2 bears inwardly against the die-support F7 and forces it and the die F6 inwardly and downwardly. When said wedge and traveler move in the opposite direction, the spring f4, through the rod F1, throws said frame F7, withv its die F6, outwardly and upwardly. In the reciprocating movement of the traveler F the rod F10 vibrates to the same extent from the fixed point of its passage through the bracket f 8, vand to permit this vibration of the rod, and the simultaneous longitudinal movement thereof, due to the spring]4 and wedgegz, it is sufficient to makeV a hole Ain said bracket for the reception of said rod somewhat larger than the rod itself. The slide G rests upon the upper plane snrface of the bed A; but the bar G is elevated above said bed, and is supported at its front end by thedepressed part ff', Figs.,2, 4", of the reciprocating traveler F. As the said bar G is subject to ,wear at its wedge-shaped end, it is desirable to make the same renewable,

able recess in the adjacent end of theslide G- and held therein by a setscrew, g3.

K represents a bell-crank lever. (Seen detached in Fig. 5, and applied to the machine in Figs. 2 and 4.) Said lever is pivoted to the bed of the machine at 7c by a vertical axis, and,r

as here shown, has its short arm 7c extended in front of and adjacent to the iiy-wheel B on the shaft B in position v to be engaged by the cam 7c3, attached to the periphery of said flywheel. The long arm 7c2 of the lever K extends forward to a point opposite the dies of the machine, where it bears against the end of a rod, L, called a clearing-rod, which passes through the traveler F and through the rearward extension of the adjacent stationary die F5, in position, as shown in Fig. 3, to strike the spike andto throw the same laterally off the su pportingdies when the die F6 is raised, in order that it may drop between the dies F and FG and out of the machine. The rod L, of course, shares the lnovement ofthe traveler F, in which it is mounted, and is therefore not attached to the bellcrank, which is st ationary. Between its head L2 and the traveler, or, if present, the supporting-bracket L, is interposed a spring, L', which withdraws the rod the moment the lever K escapes the cam k3.

As above stated, the several parts G, D, F, and E are actuated by cams on the shaft B. Said cams are numbered 1, 2, 3, 4, and 5, in their order from the right to the left, as viewed by one standing in front of the machine or ad. jacent to the traveler F, cam N o. l being for the actuation of the lever G, N o. 2 for the pointing-die lever D, No. 3 for the `forward movement of ther traveler F, No. 4 for the rearward movement of said traveler, and N o. 5 for the cutting-lever E. Another cam, N o.l 6, is also shown in Fig. 2 of the drawings, being intended for the actuation of an automatic feeding device, separately shown in Figs. 8 and 9, and hereinafter described.

If desired, the clearing-rod L for throwing the spike from the dies may be actuated'by a cam .on the shaft B, instead of by one located` upon the periphery ofthe fly-wheel, as shown, although, in view of the rapidity ofthe motion desired on the part of said clearing device, the construction shown is preferable.

The manner in which the several cams are arranged or timed on the shaft B is proximately Vshown in Fig. 13, wherein the numerals designating Ythe cams are accompanied by the letters applied elsewhere in the drawings to the `parts respectively actuated thereby.

The order of the movements of the several working paris of the machine will be further referredto. The cams may vobviously be variedin their relative positions to give the required movements of the said working parts,-

roc

IIO

The cam No. 1, for actuating the wedge, is preferably circular or merely an eccentric wheel fitting between the arms g'g on the slide G. vThe cani No. 2,' for actuating the pointing-die lever D, is of the general shape indicated in the'dei'ached view, Fig. 15.` The cam No. 3, for carrying forward the traveler F, (sh'own'only in dotted lines in Fig. 13, but

fully in Fig. 42) has a narrow projection calculated to advance the' carrier quickly and to hold'it only briefly in its advanced position.-

Cam No. 4, for retreating the traveler, has its projecting part concentric for, say,` half the circumference,and is calculated to hold the traveler in its retreated position for a considerable time to allow the blank to be fed into the machine. Cam No. 3 is located wi thin the yoke F3, and N o. 4 is located exterior' to said yoke and in engagement with the projection F? thereon. Cam No. 5, which actuates the cutter-lever E. is of the general construction indicated ink Fig. 14, being intended to rst throw down the cutter far enough to sever the blank from the blank-rod, during which time the dies Fand F firmly grip the blank, and after which the cutter further descends and operates to bend the end of the blank downward in front of the dies F5 and F, in order to dispose the metal in proper position to form the head of the spike. The cam No. 5 is constructed to then allow the cutter-lever E to quickly retreat to lift the cutter 'E3 out of the way and permit the forward motion of the traveler F, by which the blank,whilc`grasped between the dies F and F, is forced against the ,stationary die H to form the head of the spike. The cam No. Gis similar in form to the Vcam No. 2, being intended to give a quick reciprocating motion to the lever N and the conafter further described.

To facilitate the feed of the blank-rod into the machine, the stationary heading-die H is constructed with an elevation upon its upper surface and extending to its working face, in which elevation is formed a`recess, h, of such shape and size as to permit the rod to be'guided properly thereby. In the present case said recess h, as shown in Figs. 16 and 18, is substantially triangular in shape, having curved sides, hbeing-intended fora particular form of rod for making the spike shown in Fig. v7, but

the invention is not limited to the construction of a spike of any particular sectional shape, and the form of said recess h', as shown in said ngares of the drawings-is therefore not essential to my invention. The die thus recessed being the stationary cutter, it is desirable that the recess conform to the shapev of the blankrrod, iny

order` to support the latter properly when being cut. When the blank is fed inwardly by hand or by a spring-actuated feeding device-such as is herein shown and hereinafter described-a loosely pivoted at its rear end to a depending lug, s, attached to the lower rear margin of the head D2 of the pointingfdie lever D. In' this construction of the stop S its free end rides on the die I, and by reason of the relatively-elevated position of the axis of motion on-the part of the lever D, the lower part of the head D2, when raised and lowered, has a forward and backward movement by which the end of the stop is advanced and retreated, though to a less extent, because only the rear end of the stop is depressed. After acting in its position to arrest the blank, the stopis thus retreated or drawn toward the rear of themachine as the pointing-die lever descends, and by this pointing die I2 and also of the metal w-henthe latter is elongated under the compressive ac-. tion ofthe pointing-dies. Obviously, a propthan as here shown, butv the construction delmovement it is taken out of theway ofthe- Verly-movable stop may be otherwise actuated f scribed is desirable, as being both simple and effective;

The relative movements of vthe spike-form- Ioo ling parts are as follows: The blank-rodbeing brought to rest against the stop S in its more advanced posi-tion, the cutterEifirst descends and severs the blank from the rod close to the heading-die H. When thus severed, the

blank drops upon the projection]v5 and up'- on the stationary pointing-die I. When in thisv position, the blank is quickly vgrasped between the dies scent of the latter, as already described. As

F5 and F6 by the de-f soon as the blank is thus seized between the dies F51 and F-the cutter`E3, which has already severed the blankyand has been fora moment stationary, stillfurther-descends, and

by the rear bevel of said cutter the end of the blank which protrudes in front-of the diesF`5 Y. and F isbent orforced downward infront .of

the said dies, so as to place the metal in proper Simultaneously position to form the head. with or immediately after the second downward movementof the cutter the movable dies I andI2 are broughtdown upon the pointof theblank and give to the latter the-desired shape, according to the particular form of said dies. Having formed ,the'poiut of the spike,

the dies I and 12 at once rise and immediately thereafter the dies Fand Fsare carried for-V ward by the movement ofthe traveler vF so as to bear the downwardly-bent metal of theV blank against the heading-die H. rllhedies treated and opened or separated in the manner F 5 andi-F6 thereupon are simultaneously're 'l at least important, in order to permit the spike greater wear than the remaining part of this renewed or changed at pleasure. Though genalready set forth, and as soon as the spike is l releasedtherefrom the clearingrod L is thrown inward and the finished spike is thrust out of the dies and allowed to fall through the space between the arms F4.

Obviously the dies I, I and I2 may be constructed to give any desired .form to the point of the spike. In the present case they are, as above stated, intended to form a spike having a triangular shank for the greater portionof its length, and apoint or edge locatednearthe outer face of the spike, as indicated in Fig. 7. In constructing this spikepoint, which has an inclined projection or rib, t, the die is correspondingly recessed, as indicated at t' in Fig.` 7. This recess t', whichforms the rib t upionfthe spike, makes the forward movement of the spike, as effected by the traveler F, essential,or

to be discharged from the machine quickly and in a horizontal direction by the laterally-clearing rod L, for, obviously, unless the spike is first drawn out of the recess t a side push upon the spike by the clearing-rod L would throw the head off the projections f 5 of the die F, but would not simultaneously force the point out of its place between the pointingdies. In forming ordinary shaped spikes, however, which are destitute of the rib t, this forward movement is not essential'to the proper discharge of the spike by a laterally-acting clearing-rod, L, though even in that case desirable. to more promptly and freely discharge the spike.

Referring now more particularly to Figs. 7 and 4,there is here shown an especial form of the stationary pointingedie I, which has novel features of construction and certain advantages in operation-that is to say,said die is made in two parts, I3 and 1*, both preferablymade of steel and secured inthe recessed and angleshaped casting J by a clamping-bolt, I5, or other suitable means. The lowermost part, I3, is made longer than I, and is provided with a shoulder, i", against which the adjacent end of the part I4 abuts. The working end or bean ingsurface of the part I* is usually subject to die, and may, in the construction described, be

erally termed a pointing-die, it will be understood that the horizontallyproj ecting portion of the die I (or in Fig. 7 the portion ofthe part I3 in advance ofthe shoulder i4) and the opposing die I are intended to bear upon the upper and lower surfaces of the blank near its point'for the purpose of straightening it. Being adj usted perfectly in line with the bearingsurfaces ofthe dies F5 and F 6, and constructed to nter between the rearward projections of these latter dies, the shank of the spike is made perfectly straight and of the desired size throughout its length at the same time that it is being pointed. The movable pointing-die I2 is preferably of uniform diameter between its front and rear faces throughout its length, in order thatlinre-forming its lower or working face after it has become worn it need be ground only on its end. Saidworking face of the die I2 may obviously be given any desired inclination or form. In the present case it is con-` structed with a slight incline or bevel to cooperate with the working face of the opposing die I, toproduce a spike-point having its cuttiug-edge-very near to the rear face of the chine calculated to make the usual form of spikepoint, wherein thc cutting-edge is about midway of the spike-shank. Next will be described a practicable form fautomatic feed for carrying theA blank-rod into the machine. Fig. 8 4isa top or plan view of this device, and Fig. 9 is a side ele-` vation, Fig. 10 being a detail of one or two suitable guides by which the reciprocating crab or gripping device is guided. In said figures, N is a vertical lever, pivoted tothe I frame of the machine by means of a horizontal vpin passing through said lever, and through lugs n, secured to the 'front margin of the opening A2 in the bed at the'point indicated in Fig. 2, and opposite the cam No. 6 on they shaft B. Said lever rises to a point above the vbed A above the level of the elevation A, inV

which is set the -headingdie II. Upon said' kelevation A4, and upon either side of the die H,are bolted two opposite guides, N', having their inner or proximate faces grooved and parallel and arranged in the direction in which the rod is tol be fed. vWithin these guides is fitted a slide, N2, beneath which room is provided for the passage of the blank-rod, a-nd upon said slide are pivoted two horizon# I tally-movable jaws,fN3 N 3, having their points directed toward the working-dies and formed `to grasp the blank-rod R.- To the slide N2., and at a point, n', between the axis and thel gripping ends` of the jaws N3, is pivoted-a transverse horizontal lever, N4, connected with the cam-lever N by a pitman, N5. Through oblique slots n2 in the Alever N4 rise pins n3, affixed to the jaws `N3 of the crab, so that when the lever N4 is vibrated upon its pivotal point n its action will be to first open the jaws of the crab by movement of thepins N-3 in the slots n2, and when said pins strike the ends of the slots, to thereafter carry the spike; but 1t may .be more inclined 1n a maroo ITS K crab bodilyforward with its jaws remaining In this movement the crab is :carried necessary, or as provided in the cam No. 6, v

and in the return vibratory movement of said lever N 4 the jawsare first closed upon the blank-rod R, and then the crab, together with the rod, is drawn forward, carrying the rod to a proper position between the formingdies. As here shown,the cam No. 6 gives only the outward movement to the crab, the inward movement being obtained by means of a spring, N6, arranged to throw the lever N into contact with or in opposition to the said cani 6.

I In the use of an entirely positive automatic feed device thestopS maybe dispensed with; 'but in the employment of aform of feedmechanism in which the forward movement .of the'blank-rod is effected by a spring-such, for instance, as that herein shown-the stopS may advantageously be retained for the purpose of insuring the accurate location of the point end of the blank over the die. I In that 1o form of feed device herein specifically described, in which motion is givenV by cam No. l6and the spring to the gripping device or crab through the medium of the lever N", which also operates to open and close the gripping-jaws,the position of the outer end of the said lever, and consequently of the crab and blank-rod carried thereby, at the forward limit of their movement may sometimes be varied slightly on account of varia.- 2o tions in the distance apart of the grippingjaws, caused by slight irregularities in the ing the heated metal to a greater-or lessfextent as the latter is more or `less soft. For 2 5 this reason the use of the stopS-is of especial advantage. in connection with this form of feed device, inasmuch as by its employment the forward movement of the blank-rod may be arrested at the same point at every recip` 3o roeation thereof.

It is obvious that in a machine for forming. an ordinary spike,-.or one requiring no recess i in the pointing-die, said pointing-die may be horizontally movable with the traveller or. 3,5 with the die F5, and that-in the present machine the horizontal part I3 of thev pointingdie (if made in two parts) may be thus movable withl the traveler. In other words, it may form a rearward extension of the projection 4o f5 of the die F5, reachingy tothe pointing-diel proper, I4.

I claim as my inventionl.
