DIE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 767,511, dated. August 16, 1904.

Application filed March 8, 1902. Serial No. 97,243. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN J UDD ABBOTT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Die-Cutting Machines, of which the following is a specification.

This invention relates to the construction of the work-holding parts of die-cutting mar chines.

It has been devised more especially for use in cutting the dies for shaping the heads of horseshoe-nails. and which are illustrated in the drawings; but it is adapted to be used generally wherever irregular forms are to be cut.

The nature of the invention is fully set forth below and will also be understood from the accompanying drawings, in which Figure 1 is a plan of the invention, and Fig. 2 is a transverse section thereof. Fig. 3 is a section on the line 3 3 of Fig. 1. Figs. 1 and 5 are sections on the lines 4 4 and 5 5, respectively, of Fig. 3.

In said drawings, 6 represents the die-block, in which the designs or dies proper, 7, are cut by the use of my invention. These are intended to be used in shaping the heads of horseshoe-nails, two of them being formed in this instance in the same block. These designs vary in depth, as will be understood from the section given in Fig. 2, and are irregular in outline, as seen at Fig. 1.

The block 6 is secured in a holder 8 by setscrews 9, and this holder is adjustable laterally in a rest 10, being clamped therein by screws 11. The rest 10 is secured upon a swinging plate 12 by a depending screw 13, passing through the plate, and the nut 14.. A thin metal plate 15, having a central projection 16, and itself securely attached to the edge of the plate 12, serves as a guide in positioning the rest, which may be set at different angles to the line of feed. The plate 12 swings upon pivots l7 and 18, the former in standard 19 and the latter in standard 20. The pivots engage the plate near is rear edge, and its forward side finds support in a pin 21, projecting from an upright 22 and entering the camslot 23 in an arm 24, attached to the swinging plate and projecting forwardly therefrom. The standards are attached to a slide 25, movable forward and back on the carriage 26 by the screw 27, and the standards may be integral with each other and with a connecting plate or frame 28. The carriage 26 is capaable of lateral movement or movement at right angles to that of the carriage on the bed 29.

The upright 22 is attached to the carriage 26, so that its pin remains in the cam-slot at all times and in all positions of the carriage, and it will be seen from what has thus far been described that if the screw 27 be operated so as to move the work forward. or back the pin 21 will traverse the cam-slot and tilt the work on pivots 17 and 18 during such movements and in accordance with the shape of the cam-slot. In this manner the depth of the cut made in the die-block by the cuttingtool 32 may be varied within certain limits without raising or lowering the tool, the depth of the cut, as well as the locating of the increased or decreased depth, being controlled by the cam, which can be varied greatly by varying the slot.

The arm 2A is preferably made detachable to permit the substitution of others having slots of different form and is attached to the plate 12 by bolt 33.

The lateral movements of the carriage 26 while the cutter is operating and by which the side lines of the design are formed are caused and regulated as follows: At 3 1 and 35 are shown arms projecting 'rearwardly from the frame 28 and adjustable toward and from each other by screws 36, passing through the standards and threaded in the downward-pro-. jecting ears 37 of the arms. The screws and ears are located in the slot 38 formed in the frame. The arms support at their rear ends the form-plates 39 and 40, the same being clamped to the arms by the set-screws 41. A stationary guide 43, provided with antifriction-rollers each adapted to bear against one of the form-plates, is located as shown, so that when the work is moved toward the rear the form-plate will come in contact with the guideroller and be deflected laterally as the backward movement progresses, thereby giving the cut made by the tool an outline corresponding to the form-plate. This result is obtained without affecting in any way the alreadyde scribed tilting of the work-holder and is entirely regardless of that feature. As shown at Fig. 1,the right-hand form-plate 40 is in operative relation to the guide 43 and is adapted to cause the cutting of the right-side outline of the design. The pattern 39 at the other side will cause the cutting of the left-side outline.

The pivot 17 has no vertical adjustment; but pivot 18 is supported in a block 4:5, which is adjustable vertically in the standard 20 by the screw 46, which is operated either by the knurl 47 or by its head. The screw is secured in the block 45 by transverse screws 48, entering an annular channel at lower end of the screw, as shown, and the block is locked in its adjusted positions by the set-screw 51. The frame 28 is locked in the slide by screws 49 and filling-block 50. A plate or bar 52, secured to the frame 28 by screws 53, serves to hold the arms 34 and 35 down to the frame, and the arms are slotted transversely, as at 54, to give room to the screws and permit the adjustment of the arms.

I claim- 1. The combination with a stationarily-located cutter or milling-tool, of a work-holder rocking on horizontal pivots located at opposite sides of the tool. one of said pivots being vertically adjustable, a slide supporting said worleholder and adjustable to different positions transverse of the line of feeding movement, and a carriage supporting said slide and movable in line with the pivots to feed the work past the tool.

2. The combination with a stationarily-located cutter of a work-holder supported upon. horizontal pivots mounted in a support movable so as to feed the work to the cutter, said support being also movable transversely with respect to the line of the feeding movement, a form-plate and a stationary guide for imparting such lateral movement, substantially as specified.

3. The combination with a stationarily-located cutter of a work-holder supported upon horizontal pivots mounted in a support movable so as to feed the work to the cutter, said support being also movable transverse] y with respect to the line of the feeding movement, a form-plate moving with said support, and a guide bearing on the form-plate and acting to deflect the support during the feeding movement, substantially as specified.

4:. The combination with a tilting or swinging work-carrier, of pivot-bearings for said carrier, one of said bearings being vertically adjustable, substantially as specified.

5. The die-cutting machine having in combination a work-carrier having both a forward feeding movement and a tilting movement, and also capable of moving transversely and of being adjusted vertically at one end, of means for causing the feeding movement, means for tilting the carrier and means for deflecting the carrier laterally during its forward feeding movement, substantially as specified.

BENJAMIN J UDD ABBOTT.
