lVhen the machine is con operation .of its perte 111" yfollows: The

of the frame. The 'plates 5 are recessed to admit the beam plates and to forni the inside vertical supporting surface jfor the lower beam. 16 also exten'ds over but clears the bars 13. The supporting points of the plates 16 are 1 on the bars 17. The bed 18 on which the dies are secured is placed between the plates v,16 on which lit rests.

formed by the plates described is secured rlhe lower beam `in place by the plates 14. The vertical adjustment of this lower beam is effected by the movement ofthe screws 10 and 11, by which the wedges slidable on each other and between the top of the blocks 7 on which they rest, and the bar 13.0n which the completed beam is carried. `The upperv 'beam consists of the plates .20 and 21 and 23. These plates are inserted'in the frame in the. same way as the lowerbeam. The

. plates 19 are secured in position; the eccentric' connecting rods 31 are placed in positionv on the shaft 30 and in the bearings 25.

y AThe parts 29 are secured to the

plates

20 and 21.' The' connecting rods 27 are placed in shallowbore in the heads of the eccentric connecting rods 31 and in the like recesses in the blocks 26. The screws 28 are then adjusted to thrust the head of the rods into close movable contact .with the blocks 25.. When the parts are so connected, the rotationof the shafts operate the connecting lro'ds 31. The downward thrust of these rods on the bearing blocks 25tixed in the plates 20 and 21' force down those plates and the die plate 24, by which the-material inserted between the dies secured on the die plates- 18 and'24 is formed, cut or pierced. -The upward movement of the rods 31 acting throughthe connecting rods 27 and blocks 26 lifts the

plates

20, 21 and 24. The screws 28 are adapted to take up all lost motion 'between ybearing blocks 25 and head of the rods 31.

What I claim as new and desire to secure byl Letters Patent is:

1. In a machine of the kind described, the

combination with a frame consisting of two pairs of end plates, `the plates ofeach pair being spaced; of adjustable means secured plates, adjustable means secured to said.

plates adapted to support the lower beam of said machine; of a lower beam consisting of two outside plates adapted to rest ver- The upper part of the plates tically on said supporting means, and two inner plates supported. vertically on two transverse bars extending through said outer and inner plates, said inner plates being adapted to support a die plate above said outer plates as described.

3. In a..maclhii`ie of the kind described the combination with a frame, and adjustable l means therein adapted to support the lower beam; of a lower beam consistingof a plurality of plates adapted to rest on said supporting means in said frame, and a plurality of plates adapted to support a die plate, said plurality of plates being supported by said first mentioned plates, and means adapted to form the supporting connection between said supporting and supported plates.

` beam consisting of two outer plates and two inner plates, said plates being disposed vertically in relation to said frame and Vto each other, means adaptedto secure said outer plates to said frame, and means whereby said inner plates can be connected together and means adapted to move said inner plates vertically between' said outer plates, said inner movable plates being adapted to support a die plate. i

6. In a machine of the kind described, the combination with a fra-me and a lower die plate beam supported therein; of an upper beam consisting of a pluralityA of plates vertically disposed in. said frame, a part of said plates being xfed in said frame, and the other part being connected together amd movable vertically between said xed plaftesf and means adapted to move said connected plates as described, said movable plates laeing adapted to support a die plate.

7 In a machine of the kind described, thev combination with a frame and a lowerA die plate beam supported therein, and an upper beam consisting of a plurality of outer plates iixed'in said frame, and inner plates movable vertically. between said outer plates, and means adapted to move said linner plates; of adjustable means connectingsaid inner plates and said means for moving said plates, as described. l

8. In a machine of the kind described, the combination*consisting of a frame, a lower die plate supporting beam consisting of outer plates supported in Said frame and inne? plates supported by said outer plates,

l n a i l move said lnner plates, and means adapted means aclapte t0 adjust said beam in said to adjust the positions of said beams in relaconsisting of outer and inner plates, said outer plates being ixed in said frame, and said inner plates being movable vertically between said outer plates, means adapted to frame, an upper die plate supportixigibea'm tion to each other as described.
