OF BALTIMORE CITY.

v No. 844,171.

Specification of Letters Patent. I

Patented Feb. 12, 1907.

Application filed December 14,1905. Serial No. 291.916.

To aZZ whont it may concern:

Be it known that I, JOHN ARMSTRONG MOANULTY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Counter-Blocks and Dies for Stampin -Machines, of which the following is a specification.

My invention relates to rotary machines for cutting out blanks or articles from sheet material, and particularly to machines of this class in which are employed counterblocks and cooperating knife-edge cuttingdies-such, for instance, as in the machine disclosed in my application of even date here with, Serial No. 291,915.

The objects are to provide means whereby knife edge cutting dies may be operated against metallic counter-blocks without i11- jury to the dies. These objects I attain by means of the mechanism shown in the accompanying drawings, forming a part of this specification, in which- Figure 1 is an elevation of the end of a rotary cylinder containing my flexibly seated counter-block; Fig. 2 is a part section view of the counter-block, showing details of seating and adjustment. Fig. 3 is a detail view showing relative position of the counter-block and cutting-dies. Figs. 4, 5, and 6 are detail views of counter-block parts. Fig. 7 is an elevation of one end of a rotary cylinder containing flexiblyseated cutting-dies. Figs. 8, 9, and 10 are detail views of cutting-(lies.

20 and 21 are rotary cylinders and correspond with numbers designating like parts in the application above referred to. The cylinder 20 is bored out at intervals of its circumference to receive cutting-dies and to provide space under the cutters to receive flexible cushions 71, which provide a yielding seat for the cutters of such a nature as to permit the cutters to cant in any direction to make a perfect contact with the faces of the counter-blocks, whether the latter are perfectly set or may have slight irregularities or depressions in their faces. The cylinder 21 is likewise bored out at corresponding intervals in its circumference to receive counter-blocks 72, including flexible cushion-rings 73, which surround the counter-block stems under their heads. These cushions, fitting neatly in the spaces around the counter-blocks, hold them in their normal position to receive the cutters against them, yet yielding to a limited degree in every lateral or transverse direction required to accommodate to any lateral. or transverse strain that might be brought to bear on them by any action of the gearsoperatingthe cylinders or any lead or dragging action of the cutters or any jar or twisting of the machine.

The enlarged portions of the seats are made sufliciently deep to receive flexible cushionpieces 7 4, which form a yielding seat for the inner ends of the counter-block stems and provide for a slight receding action of the counter-block when the cutter-knives are brought in contact with its face with greater force than maybe required for cutting the materials being operated upon.

To provide for taking up wear of the counter-blocks and to set them outward after redressing, hollow adjustment-bolts are threaded through the cylinder-shell from within by which the yielding seats and counter-block may be forced outward. The adjustment-bolt may be provided with a jamnut 76 to retain it in position when set.

To hold the counter-block down in its seat with any degree of pressure desired, a drawbolt 77 is hinged in the body of the counterblock stem, preferably by means of a hingepin 78. Said draw bolt extends inward through the set-bolt and is provided with a draw-nut 7 9 for obtaining the desired tension on the flexible seatand a jam-nut 80, which locks the draw-nut.

What I claim as new, and desire to secure by Letters Patent, is

1. In a rotary machine for cutting articles from sheet material, the combination of a pair of members rotating relatively to one another and provided respectively with a cutting-die and a counter-block adapted to cooperate to cut the material as the members rotate, one of said cooperating parts being mounted to yield at an angle to the direction ofthe cutting pressure.

2. In a rotary machine for cuttingarticles from sheet material, the combination of a pair of members rotating relatively to one another and provided respectivelywith a cutting-die and a counter-block adapted to cooperate to cut the material as the members rotate, one of said cooperating parts being mounted to yield at an angle to the direction of the cutting pressure, and the other of said parts being mountedto yield in the direction of the cutting pressure.

3. In a rotary machine for cutting articles from sheet material, the combination of a roll, cutting-dies yieldingly mounted on said roll, a second roll, and counter-blocks yieldingly mounted on said second roll and adapted to cooperate with the cutting-dies to cut the material as the rolls are rotated.

4. In a rotary machine for cutting articles from sheet material, the combination of a roll, cutting-dies on said roll, a second roll, and counter-blocks mounted on Sitiii second roll to cooperate with the cutting-dies; said blocks being adapted to yield transversely to the direction of the cutting pressure.

5. In a machine for cutting blanks or arti cles from sheet material, the combination of a pair of rotary members provided respectively with circumferentially-disposed knife edge cutting-dies and counter-blocks cooperating therewith to cut the material by the'action of the dies rolling over the blocks one of each pair of cutting parts being adapted to yield transversely to the direction of the cutting pressure in order to avoid breaking the cutting edge by the rolling action.

6. In a machine of the character described having a knife-edge die and a counter-block adapted to cooperate and mounted to rotate relatively to one another, a mounting for the counter-block permitting the block to yield transversely to the cutting pressure.

7. In a machine of the character described, comprising relatively rotating members provided respectively with knife-edge dies-and cooperating counter-blocks, mountings for the counter-blocks which permit them to yield transversely to the direction of the cuttingpressure and mountings for the knife-edge dies which permit them to yield in the direction of the cutting-pressure.

8. In a machine of the character described comprising relatively rotating members provided respectively with knife-edge dies and cooperating counter-blocks, mountings for the counter-blocks whichpermit them to yield both in the direction of the cutting pressure and laterally thereto.

9. In a machine of the character described comprising rotary members formed with peripheral openings and with knife-edge dies and counter-blocks mounted in the openings of the respective rotary members in position to provide pairs of cooperating cutting members; a packing of yielding or cushioning material interposed between each cutting member and the rotary member in which it is mounted.

10. In a machine of the character described, comprising rotary members provided respectively with knife-edge dies and cooper ating counter-blocks, said counter-blocks being mounted in depressions or seats in one of the members, movable transversely-there in and having a set-screw which sustains it in the direction of cutting pressure by permitting such transverse movement.

11. In a machine of the V character described, the combination of the rotary member, the counter-block inserted therein for the purpose set forth, the set-screw for sustaining said counter-block in the direction of cutting pressure and a draw-bolt connected with said counter-block and adapted to draw it in a direction opposite to the pressure imposed by the set-screw.

12. In a machine of the character described, the combination of the rotary member, the counter-block inserted therein for the purpose set forth, the set-screw for sustaining said counter-block in the direction of cutting pressure and a draw-bolt connected with said counter-block and adapted to draw it in a direction opposite to the pressure imposed by the set-screw, said draw-bolt extending through the set-screw and connected with the counter-block.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. MOANULTY.
