MACHINE FOR PUNCHING,

CUTTING, SHEARING, 80C.

SPECIFICATION forming part of Letters Patent No. 621,097, dated March 14, 1899.

Application filed May 16, 1898.

, clear, and exact description.

The present invention relates to apress in which the pressing-stamp has not merely a single tool or die, matrix, or the like, but by special construction of the head of the press any desirable number of tools entirely different in dimensions or in their operations may be introduced.

The invention is shown in the annexed drawings, in which Figure l is a front view of a press constructed according to this invention; Fig. 2, a part sectional side elevation, andFig. 3 a plan of the same. In the suitably-constructed machine-frame athe eccentric-shaft o, furnished with the eccentric b and the handle d, is seated. In place of the handle cl a pulley of suitable dimensions may be employed equally well, or the whole driving apparatus may be entirely replaced by one of those hitherto in use and suitable for the purpose.

The press-head e of the machine is not massive in construction, as hitherto, but in its outward appearance more resembles a frame. It is furnished at the back, as ordinarily, with dovetails, which, exactly as in other apparatus of the kind, can be forced by means of screws and adjusting-blocks to slide properly and surely on the prismatic guide f. In the middle of the press-head e is an opening g, bounded by arcs of differentradii and acting as a cam. In the lower slide of the opening g is a small semicircular groove h, which serves for guiding the pressure=block 't'. The

eccentric b, in the present instance the pressdriving pin, runs between the upper-limit curve of the opening 9 and the block 13, and therefore raises the whole apparatus, while when the eccentric-pin descends the whole press-head is pressed down with the assistance of the pressure-piece i.

The revolving ring is a characteristic feature of this press. It is exactly fitted onto Serial No. 680,862- (NdmodeL) other in regular degrees, or an gle-iron cutters,

shears, punches, or other implements may be placed on the revolving ring in any desired order. The fixing of the ring to the piece Z for the purpose of exact adjustment of the tools is efiected in a suitable manner by means of a set-stud, a block, or in any other suitable way. The motion of the eccentric-shaft c or of the eccentric b is followed by that of the Whole revolving ring, as well as that of the instrument which. has been adjusted for cutting, the motion of the ring and head 6 being regularly up and down.

At a suitable distance below the revolving ring or the press-head a similar support to the one Z, hereinbefore referred to for receiving the revolving ring, is fixed onto the machineframe Cb. This supportalso carries a revolving ring, which can be fixed by means of blocks or any other suitable means, such ring conveying in the same graduation the matrices or counterimplements corresponding to the punches or the like.

As will be seen from Fig. 1, the rings in the machine represented carry an angle-iron cutter, shears, and six perforating or hole punches. The tools can, as a matter of course, be put together in any desired manner, however difierent the driving apparatus for the machine may be and whatever may be the fitting out of the several parts without in any Way affecting the scope of the invention.

What I claim, and desire to secure by Letters Patent, is'- 1. Ina machine for punching, cutting 82c. the combination with a supporting-frame, of a vertically-movable head, a tool-holder car ried by and adapted to be adjusted circumferentially upon said head,and a holder adapted for annular adjustment and also adapted and cireumferentially adjustable upon said head, and having a slot through which the eccentric-pin projects and bears upon the upper Wall of the slot, the opposite Wall of the latter being provided with a groove, and a piece having one end hearing in said groove and shaped at the opposite end to form a hearing for the eccentric-pin.

In Witness whereof I subscribe my signature in presence of two Witnesses.

JULIUS KEIM. Witnesses:
