MACHINE FOR CUTTING CARDBOARD OBI-.IQUELY.

SPECIFICATION forming part of Letters Patent No. 589,075, dated August 31, 1897.

Application filed A il 15,1895. Serial No. 545,812. (No model.)

To all whom, it may concern:

Be it known that I, ANTON. WALDEMAR DARRE, a subject of the King of Denmark, residing at Oopenhagen,'in the Kingdomrof Denmark, have invented certain new and useful Improvements in Machines for Cutting also unhealthy, and consequently costly, it

will be of considerable advantage if it can be effected by the aid of machinery. The present invention embraces a machine for this purpose, this being so constructed that the cardboards, fixed in a press, are brought successively against a knife reciprocating at right angles to the direction in which the press travels and which, during its forward move ment, cuts the edges of the cardboards on the slant and returns out of contact therewith.

In the annexed drawings, Figure 1 is a plan, Fig. 2 a side sectional elevation, and Fig. 3 an end sectional elevation, of a complete machine; Fig. 4, a vertical section of the knifeholder 3 Figs. 5 and 6, a perspective view and side elevation, respectively, of the knockingon-end box; Figs. 7 and S, a perspective View and side elevation, respectively, of the cardpress; and Fig. 9, a front elevation of the knife-holder. I v

The machine consists of two checks at, on which slides a carriage m, having means by which the clamp can be fastened. Extending across the cheeks at one end are the slides 19, in which slides the knife-holder. holder is connected to the eccentric disk ct by a rod 0, so that it is reciprocated when the disk is revolved.

The knife-holderb, Figs. 1 3, 4, and 9, con-- sists of a block I), moving in the slide 1)., and to which is secured the sliding piece b in such a manner that it may be raised or lowered relatively to the block b by means of the regulating-screw j, which engages with a nut in the sliding piece. A disk 6 is pivoted Said knife-.

upper end provided with an additional piece The boltg hasa vertical recess g for the knife d, which is held in this recess against the 'frontsurface of the disk 6 by means of ascrew g. The position of the disk 6, and consequently of the parts attached to it, in relation to the front surface of the sliding piece can be varied by means'of a screw f in such a manner that the knife can be placed in a more or less slanting position.

As above mentioned, the knife-holder Z) reciprocates in the slide Z). At the end of the forward movement the foremost hook of the movable plate K, which is mounted on the top of the sliding piece 5 strikes against a projection Z, fixed on the machine-frame, so that said plate is driven back. This movement turns the small lever or pin it, one. end

of which extends into a recess in the plate K- and which is pivoted in h,so causing the hook 7b, which is connected with the lever h, to engage with a recess in the piece 7. on the disk 6 and revolve the latter, thereby raising the knife-edge, which consequently, during the return stroke, is then held free of the card-v boards. By this means the jamming of the cuttings between the knife and the cardboards is prevented. The other end of the piece 2' is connected to a spring d,which normally holds the piece against the adj usting-screw 01 The friction between the plate K and the sliding piece 5 is, however, so great thatthe spring cannot move back the disk e when itis turned backward by the lever h.

In the backward movement of the knifeholder the hindermost edge of the plate K pushes against another projection Z, which moves the plate K forward again, causing the lever 7t to cease from drawing in the projection 2', and then the spring d brings the disk 6 and the knife d into position for cutting.

The sliding carriage m, sliding upon the cheeks n, is worked in the following manner: The machine is worked by means of belt and pulleys or by a hand-wheel fixed at the end of the axis 0. On the axis 0 is fixed a collar or box 1), provided with a cam p, which bears against a roller 0 on the upper end of a rod g. This rod has also in its upper end an elongated hole for the shaft and is held against the end of the box by means of a collar 0, fixed to the shaft 0. The lower end of the rod q is hinged to a lever q, pivoted on the shaft of the wheel 8. \Vhen the shaft 0 is rotated, the cam 13 will reciprocate the rod q, and thereby oscillate the lever q, so that the pawl r on the lever, acting upon the toothed wheel .9, turns this wheel around, while at the same time another toothed wheel .9, placed on the same axis as s, engages with a toothed bar on the upper edge of the sliding bar. In order to prevent the sliding barfrom suddenly backing from some cause or other, another pawl a" is provided, which by engaging with the wheel 3 stops an y retrograde movement.

If it is required to bring the sliding bar back again after its forward movement, this is done in the following manner: By turning the hand-lever 11 the escape-lever u is set in motion and the two pawls r and a" are disengaged from the wheel .9 by means of the pins 0: and st, fixed to the lever u. The escapelever 11. is an angular lever fixed in one end to the axis of the ha-nd-levert and near its other end pivoted on the axis of the wheels. The hand-wheel t is then turned, and the toothed wheel 1/, Fig. 3, engaging with'the rack placed on the lower side of the sliding carriage, is put in motion and the sliding carriage drawn back.

The clamp placed between the sides of the sliding carriage, (see Figs. 1 and 2,) in which the card-press, Figs. 7 and 8,is placed during the cutting operation, consists of a plate it, which at the top can turn in the sliding carriage m upon two pivots r, Fig. 1, and leaves a margin for the hook of the press. Besides this it is provided on the under part with two upright arms r, bet-ween which is placed a bolt F to which is pivoted the frame 10 and around which it can turn. At the upper part of the frame it are fixed two bolts to, one on each side. These pass through two holes at the back of the plate r and are here united with a cross-bar w", in which is the boss for the han d-screw a, which acts against the plate 1'. iy means of this hand-screw it; the distance between the plate 2: and the frame to can be regulated.

Behind the plate I there is a second frame z, turning on a pin .2", carried by the carriage 172, (see Fig. 2,) which is at its under part providcd with two knobs .2, resting against the plate r. This frame has at its top the'boss for the screw g which likewise acts against the plate a, which by turning the screw 1 can be raised or lowered, thereby raising or lowering the frame 11'.

The card board-press in cutting works upon the projecting edge of the plate 1:, Figs. 7 and S, and it is firmly screwed between the frame 10 and the plate r by the hand-screw 0:. Then careful examination must be made as to whether the cutting-surface lies exactly hori zontal, and this is done by moving the frame on, which moves between a pair of brackets on, fitted above the carriage m. Over these brackets, if necessary, the frame, together with the press, may be raised or lowered somewhat by turning the screw 1 and then the cutting may proceed.

The cardboard-press shown in Fig. 7 in side elevation and in Fig. 8 in plan, in which the cardboards are put during the cutting, consists of a bottom 1, two side pieces 2, slanting toward the front, and a plate 3 put on the top between these, which can turn upon a pin t, pivoted in the side pieces, and which plate is fastened by two bolts 5, which pass through holes in the side pieces. By turning the nuts of these bolts, for which nuts there are cavities in the bottom of the side pieces, the plate 3 is turned downward, so that the cardboards placed between this plate and the bottom are pressed firmly together. There are at the bottom two hooks 0, by means of which the press fastens onto the salient edge of the plate 4;.

In order that the cutting may be effected carefully, it is of importance that the front edges of all the cardboards should lie evenly and level. In order to attain this, a levelingbox is used, (shown in Fig. 5 in sideeleva tion and Fig. 6 in plan,) consisting of a bot tom 7, upon which are put guide-pieces Sin a slanting position, and a side piece 0. Into this box is placed the cardboard-presses shown in the drawings, there being in the bottom and side piece of the box the necessary places cut out for the projecting portions. The front edge of the cardboards is pressed firmly against the slanting pieces and then screwed down by the bolts 5.

IVhat I desire to claim and secure by Letters Patent is- 1. In machines for beveling the edges of cardboards a reciprocating vertically-adjustable knife-holder in which the knife is fixed, consisting of the slide a revolving disk c with the top piece 2', an adjustable disk 0, lever h with the hook h engaging with the piece 1} and the sliding plate 7c in combination with projections land l on the machine-frame, substantially as set forth.

2. In machines for beveling the edges of cardboards the combination of a sliding carriage consisting of the plate 1;, arms 1;, bolt 1;, frame 10, bolts 20 passing through the plate '1: and united with a cross-bar 10', having nut for the hand-screw as, another frame turning on the pivot .2, knobs z, and screw 1 by means of which clamp card-presses of various sizes can be inserted in the cutting-machine; substantially as set forth.

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