- This invention relates to machines for forming spikes, bolts, rivets,- and other similar devices', and

It consists in the combination and arrangement of its parts, for forming spikes and bolts partly by swagingand partly by pressure produced by an eccentric or cam, or their equivalents, as will be more fully explained hereinafter.

- The invention further consists inthe combination and arrangement ofthe remaining portions ofthe machine, as will be set forth.

A, in the drawings, represents the frame or table of the machine, which may be of any desired area of surface, and of suitable thickness to give it the required strength.

4From the table A project four standards, A1 A A3 .A4, three .of wh ich ext-end upward for a distance sutti- ,cient to enable them to receive and support thc driving-shaft B, and the guides for the upper ends of the eccentric-rods C, O, Cf", and Oi, which have their upper ends secured in the cap upon the top of these standards.

B represents a shaft, which has its bearings in the standards above` alluded to, at some distance from their upper ends.

To one of the outer ends of this shaft there is to be secured a iy or balance-wheel, B1, for the purpose of steadying the motion of the operating parts of the machine.

Upon the opposite outer endof this shaft is a pulley or band-wheel, over which the belt passes which drives 'the machine, while upon the intermediate portion of the same shaft there are secured four eccentrics or cams, one-of which is lettered l5", and is out'- Vside of the frame, but inside of the driving-pulley,

while the others, B4, B5, and BG, arc located between the outer standards of the frame. 'llie ollice ot" these eccentrics or cams is to give motion to thc diii'crent parts of the machine, as will be more fully described hereinafter.

G represents an eccentric-rod, which works in suitable guides, secured to the standard A1, its upper end being provided with a strap, which encircles eccentric B, while its lower end is provided with a slot, which receives the outer end of lever H, for the purpose ot' giving a reciprocating movement to such lever.

O* represents an eccentric-rod, which`l1as formed upon it a yoke, at the point where the shaft B passes through it. This yoke is of the propel' dimensions to receive the eccentric Bi, andis sojarranged, wit-h reference thereto, that as the shaft B is rotated, the said eccentric will give a vertical movement to said rod,

the lower end of which works in suitable guides' formed upon or secured to the inner face of standard A. Upon the lower portion of this rod, and upon its -inner face, there are to be formed two inclined planes or segments of circles, which form a'track to control themovcmeuts of swinging arm F, for a purpose soon to be described.l

C2 represents an eccentricrod, similar in all respects to the one last above described, except that it has upon its lower portion a rectangular formation, C5, its greatest surfaces being those which are toward the front and rear of the machine, while its edges, or parts of least surface, aretoward the standards, against which they bear, and upon which they slide,they heilig held in their positions by means 0f `suitable plates otf metal screwed to such standards. YTo the front side of the rectangular portion of rod Cl there is to be pivoted a swinging arm, F, as shown in 'fifa 1.

z:,(JC represents acum-rod, which is located between the standard's'A2 and A, its upper end being guided by the bearing formed in the cap A5, asin the cases previously described, whilefits central portion, or that which surrounds the sha-ftB, is formed as shown in iis. 2, in order that the cani l may give to the roda rapid movement, at thtl proper time for opening the dios to permit the spike which has been formed to be' displaced, and also to pei-init -the-'bar from which thc spikes arecut to be moved forward.

Upon the lower portion of this yoke, and upon its outer side, there to be a projection, which, upon its upper surface, is to be in the form of a segment of a circle, which is for the purpose of all- )win g the projection upon the side of cam BG to act upon the rod, to force it 'down upontho spike after the force of the spring which acts to give the blow has been expended, which operation will hereafter be described.

'lhat portion of this rod which is below the yoke may be rectangular', or of any other suitable form, to work in guides f-.nmed in or upon the standards A2 and A, it having4 suitable plates for holding it inposition attachedw to such standards. Tothe cxtreme lower end of this rod there is to be attachedvthe upper half ofthe die l), which forms the spike or bolt. This upper'die may he cast upon, or otherwise secured to the rod, and is to have, in its lower surface, a recess correspoinlingr to one-half of the spike or bolt to be formed therein. Upon the outer end of this die there to be secured a shear or knife, the inner edges of which shall be rin aline with, and move down upon `the outer end of the lower die, so that when the upper die comes down, this knife shall be brought in contact with the bar from which the blanks are to be cut, and cut such blanks from such bar which lies upon the tables of the machine.

D represents the upper die, above referred to, its construction and arrangement being shown in figs. l, 7, and 14.

D1 represents the lower half of the die, the upper face of which is to have a recess in it, similar' in form to the one in thc lower' face of the upper one, while upon the vertical face' of` its inner end there is to be formed a cavity, as shown in figs. 7 and v14, in which the head of the spike is.to be formed. This die is to be secured iu a projection formed upon the bed of the machine.

D2 represents the shear or knife, above referred to, it being shown Aas secured to the upper half of the die. by means of screw-bolts, by whichit is made adjustable. l

D3 represents that portion of the table, or an attachment thereto, having 4thel pins in. it tn guille the bar to the cutter.

D4l represents aspring which is to be attached to4 the standard A3, in such a manner that it shall `press upon the bar, to be. operated on. during:r the action of the cutter, but Ithat as thc die I) is raised, it shall come in contact therewith and raise it up, so that its Vertical portion shall le raised off from the bar from which the blanks to be cut, so that thc attendant may shove such bar forward while the die is in its clevated position preparatory to its being out and swagcd upon vthe downward movement of thc die.

Elrepresents a star-wheel, which llas its hearings in vears which projectfrom the bed of the machine, in

such 4a'r'nann'er that when the Wheel is in position, its

arms'shall work in 4a slot-cut through the lower diev about midway of its lower length. The office of this wheel is to remove the spike from the lower die after it has been formed. To enable it to perform this function, it is provided with a-series of arms, upon the outer ends of which there' are tobe formed hookshaped projections, which, in the rotation ofthe wheel,

come in contact with the rear surface of the spike, as it lies in the die.

El represents aspring, which is to bc'secured to the under' side of the bed A of the machine, and be curved downward, so that lthe outer ends of the arms of the '.wheel E may rest therein, and bear upon it,for the purpose of preventing the wheel from turning at the wrong time, or from turning too far, when it moved by the spring-hook El, which is tobe secured to the lower surface of the upper die, so that this die is moved upward, it shall catch upon one of the arms of wheel E, and bring it into the position shown in iig. 2, in which position it is ready to discharge a spike at the next upward movement of the die.

F represents alight-angled arln, which is to be pivoted to the rectangular.portion of the eccentric-rod 02. The lower or horizontal portion of this arm, is to be slotted to receive two friction-rollers-one, F2, upon its outer en d, and one, F1, at the point where the horizontal portion diverges from the vertical portion:

The roller F2 of v this arm, in conjunction with the inclined surfaces of the reciprocating rod C1, is designed to regulate the position of thc-arm and its roller, F,

with rcference'to the head of the spike and the dies j l) D, its'arrangement, and that of the eccentrics or cams on vshaft B, being such, that as the upper die is raised, to permit the bar from which the blanks are to be cut, to be pushed hrward until itstrikes the adj ustahle stop F3 which is secured to the lower portion of arm F, the rod which has the arm F attached to it, shall be moved up also, so that as thc die falls, and cuts the bar, and leaves a blank in the dies, a-continuous movement of the driving-slutft in the same direction shall cause the arm to descend and bend that portion of the blank which projects beyond the inner surface of thc dies downward ata right anglo, at which time the. eccentric, '133, brings the lower inclined or segmental surface of rod G1 in contact with roller F2, and keepslit in contact with the portion to' be bent, when, rin consequence of a further movement of the shaft, the arm and its rod will be raised, and th 5; roller'Fl will be carried upward `hefl -re the die com' mences to rise, and any surplus of iron that mayre- .main upon the head of the spike will be carried up-v ward, and the upper edge or arm Vof the spike will `be made square, or nearly so, with reference to its upper surface, which latter effect will be produceclby mean s of thc upper inclined surface of the rod Ccoming in contact with roller F2, and thus kecping'roller F1 in con- Vtact witlrthe head of the spike d uring thc upward move'- ment of .the arm and the rod to which itis attached. As soon as the operation above described has been performed, the die commences to rise, and thus the operation is repeatedA as often as is practicable.

G represents a spring, which in this instance issecured to the cap A5 of the frame, it being of a bent or curved form, and so arranged that its outer end sl'iall rest upon the top of the rod to which the upper or movable die is' a-ttached,.in order thatas suchl rod is carried upward by its eccentric, the tension of the springt will be aifected, and so soon as thc arm B9 has passed thc point of the yoke upon which it bears, to causo such upward movement, the spring, will act to drive the die down upon theldank withagrcat force, and thus perform the swaging-part of the operation, after whicl and bcibre the spike has been removed fronrthe dies, the cam or projection .upon the side of BG comes iucontact with the slionlder or' projection upon rod C, and presscstlc die down upon the spike, andthns the operation of forming the spike orbolt is completed. lh'e arrangement of these parts is such, that if the point of the spike is completed. by the stroke of the movable die, andthe surfaces of the 'dies come in contact with each other, then projection of cam B6 does not come in contact with the projection upon rod C, and consequently' no pressure will be applied to the die.

H represents a lever, which, in making bolts and rivets, is to be used in place of the arm F, it being pivoted to a projection upon tbe under side of table A, and so arranged that its outer end shall enter the slot in the lower end of eccentric-rod C, so that as said rod iscarried upward by its eccentric, the die which is placed in the short arm of the lever, shall come in contact witlLthat portion of the blank which protrudes through the stationary die, and upset and form a bed upon the same. In order that dies of different forms may be vused for different kinds of \vork,it'is, of course, necessary that they, and the parts to which they are attached, should he so constructed that one set of dies-may be removed, and another set substituted in place thereof. lVhen used for heading bolts and rivets, the rod C1 and arm F are to be removed, so as to permit the arm of lever H to pass into its slot in rod C. I 1 represent a pair of dies, which are to be used in heading bolts; the one having the cavity in its face, being inserted into the end of lever H for forming the head of the bolt, while the other one is to be inserted int-o a projection which should be formed upon table A in such a manner that the rod may pass through it as described in making spikes.

l' `I represent a set of dies to be used in making rivets, which are to be arranged in all respects as are those above described for making bolts.

1t will be apparent that this machine may be used in a horizontal position if preferred,A and also that `va rions arrangements of the spripgmay be adopted, other than that shown, if desired. lt will be seen,

also, that the lever H may be used for heading spikes by changing the fulcrum so as to give the bevelled form to the head thereof, for whichpurpose` different holes are provided in said lever.

Having thus described our invention.

{Whatwe claim, and' desire to secure by Let-ters Patent is- 1,. The'combination of the swaging-dies D Dl, and reciprocating pawl E, with the discharging-wheel E, respectively constructed and-arranged in relation to each other substantially as set forth.

'2. AThe combination of mechanism for operating the movable swage D, constructed and operating substantially as describedso as to loperate the movable die, first 'by'percussion and then by compression.

3. The combination of the .dies D D1, with the reciprocating header F1 and gauge F3, substantially as and for the purpose set forth.

4. The combination of the reciprocating plunger C5, elbow-lever F, and heading-roll F1, constructed and arranged, in relation` tothe dies, substantially as describedkwt'h mechanism which shall cause such heading-roll, F1, in its reci procations, to bear upon-andtraverse twice along the head of the' spike, substantially as and for the purpose set forth.

5. The combination of the roller F1, oscillating arm F, eccentric-rod C?, and reciprocating track G1, so arranged n relation to each other as to operate substantially as and for the purpose set forth.

6. The, combination, substantially as described, of the following elements, viz, dies to form the shank of the spike, a headerreciprocating in aline perpendicular to the axis of the spike, and a discharging-wheel, all

'operated by eccentrics or cams, substantiallyas set forth.

7. The combination of the lever H, rod C, and eccentric B, arranged to operate substantially as and for the purpose set forth.

In testimony whereof, we have signed our names to this specification, in the presence' of twoY subscribing witnesses.
