0 Specification forming part of Letters Patent 115,156, dated May 23, 1871.
To all whom it may concern:
Be it known that we, EZRA R. BROWN, of Manch Chunk, in the county of Carbon and State' of Pennsylvania, and JAMES LONG, of Packerton, in the county and State aforesaid,
have invented a new and useful Improvement in Punches, of which the following` is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this speciiication, and in which- Figure 1` represents a side elevation of a press for punching washers constructed in accordance with our invention; Fig. 2, a partlysectional front view of the same; and Fig. 3, a transverse section through the punch proper, taken as denoted through the line w in Figs.
1 and 2.
Similar letters of reference indicate corresponding parts throughout the several figures.
Our invention is designed for the'punchin g of washers of metal orother suitable material; and. consists in an advantageous combination of devices for operating the disch arger.
Referring to the accompanying drawing, which shows the press as operated by hand through a crank or handle, a,`but which may he driven by any other power applied to rotate a shaft, b, that has its bearing in the upper portion of the main frame A, up-anddown motion is communicated to the punch proper B by a sliding bolster, C, in the lower end of which the punch is securedand which is driven by an eccentric pin, c, on the front end of the shaft, and arranged to Work in a slot in the bolster. The punch B is of an annular construction at its lower or Operating end, corresponding With the size of the washer to bepunched, and is furthermore provided with a lateralor transverse opening, d, in it, preferably of greater cross dimensions than the lower central opening e in the punch, with The object of the vide a clearance for the burs as punched out of the Washers, and forced by the action of the punch in communication with a central core, f, in a lower die, lD, upinto the punch, said burs passing or being forced out of the opening d as they accumulate therein. The die" d is adjustable by means of set-screws,
m, within a recess in the bed E of the press,
and, like the punch, removable, to provide for the production of diiferent-sized washers by the substitution of other dies and punches. Said die, within which the punch works to force out .the washer `from the plate or sheet as the latter is laid on top of the die, is of reverse contour with the operating end of the punch, to allow of the latter working closely but freely within it when entering and leaving the same, the central core f, which projects upward from the die, entering the punch as the latter enters the die. This central core f it is preferred to attach in a removable manner to the die by forming it with a shank,
which passes through the base of the latter,
and securing it below by a nut, g. This separate Aattachment of the core provides for its removal when heated, or when a differentsized hole in the Washer is required, and substitution of another core in the same die, according to circumstances.
By means of the annular punch and die, as described, a washer is struck out of the plate or sheet at a single blow, and the burs are discharged through the transverse openin g in the punch.
i To provide for the discharge of the washer as made there is arranged below the die, and so as to project up through or into its annular recess, straddling the central core f, a forked discharger, Gr, that may be mounted by a ring, h, at its upper end, arranged to freely iit the yannular recess in the die, and serving as a base by which to discharge the punched Washer 'i above the upper face of the die, from whence it may be brushed olf by hand or otherwise. This forked discharger G descends in concert with the punch and rises as the latter ascends, in order to effect its proper action as a clearer. It may be guided and steadied in its action, and the ring h be relieved from binding in the die, and the level of the ring be preserved so as to prevent the washer from binding when being forced out of the die, by making the prongs of the forked discharger fit closely but freely the holes in the base of the die. The construction of said discharger is exceedingly simple, yet strong, being formed by merely bending a rod or wire and connecting its free upper ends by the ring h.
Various mechanisms maybe employed for giving to the discharger its necessary movements; but the following means have been found very efficient for the purpose: Arranged below said dischnrger is u rocksl1utt, lc, which is connected with the lower end ofthe discharger by :t lever, l. Another arm or lever, m, connects snid rock-shaft at its outer end with :L vertical rod, u, that carries an arm, o, which works on or over a guide-rod, q, and beurs down on, or is borne up by, a spring, o', Wound around the rod q. Connected with the upper end of the rod n is a lever, s, having its fulcrum as at u, and arranged to bear or rest upon the upper end of the sliding bolster C, that in rising acts upon the lever s as against the pressure of the spring 1*, which latter, in
specified.
