ANDREWSIEGEL,0fHydePaIk,iI1thGCOImtyOf Norfolk, State of Massachusetts, have invented a certain new and useful Improvement in Dies, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- V Figure 1 is a side elevation of the upper or movable die; Fig. 2, a side elevation of the lower or bed die with the stripper in its normal position and the plunger inserted; Fig. 3, an end elevation of the upper die; Fig. 4., an end elevation of the lower die,showing the cutter of the plunger; Fig. 5, a vertical transverse section of the upper die; Fig. 6, a vertical transverse section of the lower die with the plunger inserted; Fig. 7, a top plan view of the lower die with the plunger inserted; Fig. 8, a bottom plan view of the upper die; Fig. 9, a top plan view of the lower die with the plunger withdrawn; Fig. 10, a perspective view of the blank before being submitted to the action of the dies, and Fig. 11 a like view of the blank after it has been submitted to the action of the dies.

Like letters of reference indicate corresponding parts in the different figures of the drawmgs.

Our invention relates to that class of dies which are employed in the manufacture of axes and similar articles for giving them shape and forming the eyes to receive the handles or 'helve's; and it consists in the novel construction and combination of parts,hereinafter more fully set forth and claimed, the object being to produce a more effective device of this character than is now in ordinary use;

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.

In the drawings, A represents the bed-die; B, the upper die; G, the stripper, and D the plunger.

The bed-die is provided with a rabbet or dovetail, v, on its lowerside, to fit a corresponding groove in the bed or support (not shown) onrwhich it is mounted, the upper die being also provided with a rabbet or dovetail, (l, on its upper side,to enable it to be secured to the cross-head or plunger of the drop-press.

(Not shown.) Projecting upwardly at either end of the bed-die there is a standard, E, provided with a vertical groove, m. A vertical groove, H, which is rectangular in cross-section, is formed in the upper portion of the beddie, said groove running longitudinally and centrally of the body of the die, and opening outwardly through the standards E. Disposed in said groove, and arranged horizontally therein, is a plunger, D, provided with a longitudi= nal groove, 1', in one of its sides, a screw, f, being inserted in the body A,and projecting into said groove, the screw acting as a stop to prevent the' plunger from being entirely withdrawn.

The plunger Dis provided at its inner end with a wedge-shaped cutter, J, which is shaped in cross-section at its top, and stands centrally in the groove H, said cutter being adapted to cut or form the groove or slot-b in the blade portion of the blank K, for receiving the steel of the ax, as shown in Fig. 11.

The stripper C is rectangular in form, and provided centrally at one end with a stud, Z, which is fitted to work in the slot m of one of the standards E, and at the other end with a corresponding stud, l, which is fitted to work in a slot, 112., in the other standard E, said lastnamed stud being elongatedto form the handle L. The upper portion of the stripper, at one of its sides, is cut away at either end to form an incline, h, its under portion at the opposite side being also cut away at either end to form an incline, i, the inclines being arranged in parallelism with each other. A hole, N, is formed in the body of the stripper C, said hole being arranged longitudinally therein, and extending vertically through the center of the same from top to bottom, the

the die B at a, said spring acting contractively to draw the hook against a stud or stop, 3 projecting laterally from the body of the die. A vertically-arranged follower, O, is secured in the die B by a screw, 12, said follower being adapted to fit loosely in the hole N of the stripper O. Projecting from the lower end of said follower there is a vertically-arranged punch, Q, adapted to punch or form the eye w in the blank K.

In the use of our improvement, the dies A B being first properly adjusted and secured in the press, the plunger D is pushed in until its cutter J projects through the end of the die, as shown in Fig. 7. The blank K, (shown in Fig. 10,) being first heated, if necessary, is then placed edgewise in the hole N of the stripper O, and permitted to reston the top of the plunger D. The press is then operated to drop the die B and cause the punch Q to enter the blank and punch or form one-half of the eye 10, at the same time forcing the blank outward or expanding it and wedging it in the hole N. As the die B descends, the curved portions 1) of the hooks M strike theinclines h on the stripper 0, thereby forcing the hooks outward until the hooks proper, j, have passed the stripper, after which they are held in position to engage the stripper by means of the springs k, the hooks proper, j,being drawn by said springs inwardly into sockets 0, formed in the upper portion of the die A, beneath the ends of the stripper,when the die B is raised. The die B being down, the punch Q in the blank K, and the hooks M in position to engage the stripper G, as described, the press is now operated to raise the upper die, thereby withdrawing the punch Q from the blank and causing the hooks M to turn the stripper on its studs or journals m, the blank in. the hole N being of course turned with the stripper. After the stripper and blank have been turned, as described,the upper die B is again dropped, causing the punch Q to form or punch the other half of the eyewin theblank, after which the upper die is again raised, the punch withdrawn from the blank,and the stripper turned by the hooks in substantially the same manner as already described, the blank being left in the stripper. The plunger D is now withdrawn until stopped by the screw f, thereby bringing the cutter J into proper position to form the groove or slot 1), after which the die B is again dropped, causing the punch Q to enter the eye w and the follower O to strike the blank K and force it out of the hole N down into the groove H, the groove 1) in said blank being formed by the cutter J as the blank descends. The groove H in the lower die is slightly wider than the hole N in the stripper, and as the blank strikes the bottom of said groove it is expanded by the follower O and punch Q, so that when the upper die is again raised the stripper will strip it from the punch and leave it in said groove. The upper die, B, being again raised and the blank left in the groove H, with the eye 10 punched and the slot Z formed, the plunger l),which is then in the position shown in Fig. 9, is forced inwardly until brought into the position shown in Fig. 7, thereby pushing the blank out of the die A, and leaving the dies in readiness to repeat the operation. The sides or edges of the stripper O are rounded, and as the die B and its punch Q rise to withdraw the punch from the blank whilc'it remains in the hole N, the blank, being wedged in said hole, will cause the stripper to be carried upwardly with the punch until the studs or journalsl reach the upper ends of the slots m, when the punch will be disengaged from the blank, the

stripper at the same time being turned on its studsZ by the hooks M, and dropped onto the die A, the elevation of the stripper, as described, enabling it to be turned to better advantage than when not elevated.

The handle L is for enabling the stripper to be turned by the workman in case the hooks M for any reason should fail to perform their functions properly. It also enables the hooks to be dispensed with, if desired.

The hole N corresponds approximately in horizontal section at any given point with a horizontal section of the blank shown in Fig. 11, taken at a corresponding point before the groove bis formed, said hole being approximately of the same shape as a finished ax, and hence comparatively little labor is required to complete the ax after it leaves the die.

Ve do not confine ourselves to making the groove H wider than the hole N, as the friction produced by pressing the blank into said groove-and onto the cutter J, as described, will be sufficient usually to enable the punch Q to be withdrawn from the blank when the die B rises, without withdrawing the blank from said groove, the friction between the punch and blank being less than that between the blank and sides of the groove and cutter after the blank has been forced into the groove by the follower O, as described. Neither do we confine ourselves to the use of the groove H, plunger D, and cutter J, as the bed-die may be made without said groove, and the slot b formed in the blank by other means, if desired. One hook M may also be used, instead of two, by arranging it cent-rally of the stripper.

The device may be used in the manufacture of other articles than axes, if desired, and hence we do not confine ourselves to using it for any special purpose.

The plunger D may, if desired, be connected by suitable appliances with mechanism adapted to operate it by power. The stripper L may also be turned by other mechanical means than the hooks M, if preferred.

Having thus explained our invention, what hooks, the stripper being adapted to be re volved or turned and provided with a hole adapted to receive the blank to be punched, said hole conforming approximately in shape with the shape of the finished ax or other artiole, and the hook or hooks adapted to engage the stripper as the movable die rises, and turn the stripper and blank, substantially as described.
