: To all whom it may concern:

Be it known that I, EDGAR WEBsTER SUMMERS, of

Wilkinsburg, in the county of Allegheny and State .of

Pennsylvania, have invented a certain new and useful Improvement in Plate-Punching Machines, of which improvement the following is a specification, reference being had to the accompanying drawings,-forming part of this specification, in which Fig. 1. Is a partial transverse elevation of my improved plate punching machine, taken in line 11 in 2, Is a partial' longitudinal elevation of the same, with aportion broken away between the center and each end;

Fig; 9. Shows a diagram of the electric transmission device for controlling the operations of the punching machine. 1

My invention relates to apparatus for punching a. multiplicity of holes in metallic sheets or plates, such as rivet holes wherein a great number of plates are to be punched duplicates of each other in the arrangement and location of the rivet holes, such as plates for steel car construction and other similar fabrication, to do which I have arranged to locate a punch and its corre sponding die for each hole to be punched'in the plate or in other words to have as many punches and dies as there are holes to be punched and further, to provide for achange in location of the punches so as to punch any arrangement of holes required in any plate. In operation the plate is placed in the machine between the punches and dies and in the operation of passing the plate through the machine all of the holes are punched in the exact location required without depending on the operator for adjustment or care in the location of the holes. Further explanation of the operation will be given hereafter. V

In the'drawings I show a machine having an upright framework 1, similar to the ordinary press frame. I

show a vertically reciprocating-head 2, the guide-bars '3, the eccentric shaft 4, the eccentric straps 5 and connecting bars 6, the gear transmission 7 and motor 8 all of which provide the actuating means for driving the punch through the plate. I show the bed-plate 9 which is arranged vertically under the reciprocatinghead 2, the toggle-beams 10 and toggles 11, the eccentric tical movement of 'bed plate 9, and furnishes vertical support for bed-plate 9. vI show the guide-ways 13, which are similar to the V shaped guide-ways 0n the ordinary metal planer. These guide-ways extend continuously out each side of the main frame 1 for such a distance as is required for handling and supporting the maximum length plate to be operated upon or punched. I show the side-bars 14 ofthe dieholding frame which has a V shaped bottom to conform with the top part of guide-ways 13. I show the crossbars 15 which are bolted between the side-bars 14 and which may be located in any position from end to end of side-bars 14 by means of clamping or bolting in the continuous '1 slot 16. These bars 15' are the dieholding bars and are provided and arranged both transversely and longitudinally the same M20 and 21 as shown in Fig.4, the object being to locate a die for each hole that is to be punched in a particular plate, fixing these dies in position so as to punch a great many duplicate plates, changing the Whole arrangement or location of dies when punching a different arrangement of holes. I show the side frame- bars 17 and 18, which are the longitudinal pieces of the upper or punch carrying-bars and also the end cross-bar 19 which connects 17 and 18 at the outer ends of the punch carrying frame. A similar cross-bar may be used at the outer end of'the side-bars 14 of the die carrying-frame. Cross-bars 20 and longitudinal-bars 21 of the punch carrying-frame are of similar construction to bars 15 and have their attachments to side- bars 17 and 18 adjustably connected, the same as in 16. The bars 20 and 21 are arranged soas to carry the punches vertically over the dies and registering therewith. I The side-bar 17 is hinge connected to one of the side-bars 16, the upper frame can be rotated about this hinge connection 22 thus permitting the upper or punch carrying frame to be raised at one edge-for the purpose of inserting the plate to be punched, which when in position rests on top of the dies 23. By lowering the upper frame over the plate, the punches 24 are then in position registering over the dies 23. I show the rack 25. attached to side frames 14 and the .pinion 26 which is located on cross-shaft 27 and is gear connected by means of gear-wheel 28, drivechain 29 and pinion 30 tomotor-shaft 31, which motor furnishes the operating power for moving the die-holding frame 16 along the ways 13. I show the large sized detail of the punch and die in Figs. 5 and 6. In this detail the die holding-bar 15 and punch holding-bar 20 are,of similar construction. The 'die holding-block 32 and the punch guide-block 33 have dove-tailed sides 34 which are locked in position by cap-bars 15 and bolts 15". The dies 23 are of the usual form and rest in a recess in the upper part of 32. The punch 24 is of the usual form'and is attached to the special punch-carrying-shank 35 by means ,of the usual flange-nut 36. The

punch carrying-shank 35 is provided with a head 37, which engages the upper end of the spiral-spring 38, which spring is provided for the purpose of assisting in the removal of thepunch from the plate after the hole is punched. Figs. 7 and aresimilar to Figs; 5 andfi,

difiering however in the arrangement for clamping the ,ing. The electric controlling device in Fig. 9 and shown partially in detail in Fig. 2 is the usual arrangement in use on machinery having intermittent motion, for which I make no claim.

In operating the machine the die and'punch holdingframes with their side bars, which for convenience as a whole I will call the platen, this platen is moved to- ,wards one end of the ways until the end of the platen is past the main frame 1, the. whole platen being clear'and' free from this said mainframe, so as to permit of raising the upper or punch carrying portion of the platen; The plate then to be punched is'placed on the lower frame or. die portion of the platen, shoving the plate against stops that have been located to suitthe particular plate which adjusts it in position to receive the holes where wanted. The punches or upper partfof platen is then lowered on top of the plate and is ready for the opera tion. The machine is then started which causes the platen to move into frame-1 until the punches at the end of'the plat'e'n come'under the reciprocating head 2. The platen is then stopped and by any suitable actuating mechanism the power is turned onpausing head 2 to move .downward' engaging punch shanks 37 and thereby forcing the punches through the plate. The head Zreturnsto its upper position and by any suitable operating mechanism has its'power cut out while the power is applied to driving the platen forwarduntil an other lot of punches and dies come under. the. head 2.

'- The platen is again brought to rest while the punching operation is performed the same as above described for the first lot of punches coming under head 2. This op eration is'repeatedthroughout the length oftheplaten, or of the plate withinthe platen which is beingpunched.

When-allof the punches have been driven through the 7 plate the platen is run out from under head 2; The upper or punch portiono f the platen is rotatedupward,

permitting the removal of the plate and the insertion of another one. By this means any number ofplates may be punched, having the assembled location of punchholes exact duplicates of each other. This i's a difiicult matter to perform with machines in use previous to this invention, and especially sowhere the holes must be arranged irregularly over the surface of the plate. The

toggle-beams 10 and toggles 11 supp0rti'ngbed-plate9 are for the purpose of lowering bed plateil during the time when theplaten is naming, and it is lowered for the purpose-of fleeing the lower end of the dies from obstruction. The bed-plate 9 is brought up in contact with .the bottom of the dies during the punching opera tion. The wedge blocks 41in Figs.'2 and 4 are adjust-" ably arranged in '1 slot 42 in Fig. l for the pusposeof actuating'an'y power controlling device for controlling the starting and stopping operation. 7 p

4 Many variations may be made in the form and arrange.- ement oi the machine, the punch and die carriers, the

power actuating mechanism, the die-and punch holders, and the stopping'devices, without departing from my invention:

I claim:

1. In a plate punching machine, a press haying a reiL-ip:

rocatlnghead, a movable frame in which a plurality of punches and dies are adj'ustably locatedpver an area greater than the area of the reciprocating head and means for moving the frame relatively to the reciprocating head.

so as to bring allot the punches within the area or action of the reciprocating head.

2. The combination with a press, of a table in the press, punches and punch-dies located on the table means whereby the punches and punch dies may be adjusted to any desired position and a means'for moving the table laterally step by step through the press.

- 3. A punching machine having a punch and die for each hole to be punched inthe plate, the punches and dies being adjustabiylocated on a framework moving laterally step by stepthrough the machine. v

4. A punching machine havlng a plurality of punches and'dies; the punches and dies located on a movableplaten having a framework or bars to which the punches and dies areadjustably "clamped. p

5. The combination with aj press, of a platen carrying punches and dies and moving under the press, the platen having a top hinged along one edge to the, platen-frame.

' 6. The combination with a press, of a plateau movable transversely thereof, punches mounted on'the platen yieldlngly held in retracted-position, and dies on the'plate'n for cooperating with the punches.

- 7 lh'e' combination with a platen movable transversely thereof and provided with punclis'and dies, and a bed on which the dies are sup portedin aline'ment with the punches during 'the punching operation.

In testimony whereof, I have hereunto set my hand.
