To aZZ whom, it may concern.-

Be it known that I, GEORGE W. JORDAN, a citizen of the United States, residing at Worcester, in the county of \Vorcester and State of Massachusetts, have invented a new and useful-Improvementin Machines for Scoring Cardboard, of which the following is a specification, reference being had to the ac companying drawings, forming a part of the same,.in which Figure 1 represents a top view of a scoringmachine embodying my invention.

Similar letters refer to similar parts in the different figures.

My invention relates to certain improve ments in that class of scoring-machines which comprise two scoring mechanisms for the purpose of scoring a sheet of cardboard in two directions at right angles to each other to allow the cardboard to be bent on its scored lines in the manufacture of a paper box, the machine embodying my present invention being what is known as a double-scoring machine; and my present invention consists in certain features of construction and arrangement of parts, as hereinafter described, and specificallypointed out in the annexed claims, by which certain advantages are secured, such as simplicity of construction, efficiency and accuracy of operation, and automatic.

control of the cardboard, as hereinafter set forth.

Referring to the drawings, A denotes the first feed-table, upon which a sheet of cardboard is fed to the first scoring mechanism, it being pushed forward on the table A by hand by means of a pushing-plate A, projecting laterally from a sliding plate A ,which slid es upon and is guided by the vertical mem her A of an angle-plate A adjustably attached to the feed-table A. by a tighteningbolt A The first scoring mechanism consists of a bed-roll A and rotating cutters A held in frames A adjustably attached to the under side of a cutter-barA which is journaled at its ends in the framework of the'niachine in order to allow it to be rotated to raise the retating cutters into convenient position for adjustment, said cutter-bar A being held from rotation during the operation of the machine by a sliding bolt A in lugs projecting from the side of the cutter-bar, wit-l1 its end carried by the springs A into a hole in the framework of the machine. The sliding bolt A is withdrawn to allow the cutter-bar to be rotated by means of the pivoted lever-handle A12 JAM.

As the sheet of cardboard passes from the feed-table A over the bed-ro1l A it passes beneath a p1'essure-1')late A (Shown in sectional view and on a larger scale in Figs. 11

and 12.)

The pressure-plate A eonsists of a curved sheet-metal plate provided at its upper edge with gndgeons A A, which are journaled in a sleeve A held in and capable of being slightly rocked in the forked ends of the bracketsA which project from the framework of the machine. The sleeves A are provided with the tailgieces A", which extend between adjusting-screws A A held in lugs projecting from the brackets A the adjustment of the screws serving to rock the sleeves A slightly within their forked bearings, so as to change the position of the pressure-plate A and vary the distance between the lower edge A of the pressure-plate and the bed-roll A.

Flanged collars A are attached to the godgeons A by set-screws A and inclose torsional springs A one of which is shown in Fig. 12. One end of the torsional spring A engages the collar A and the opposite end engages the sleeve A so the tension of the spring will be exerted to prevent the rocking of the gudgeons A in their bearings by the rising of the lower end A of the pressureplate A. The adjustment of the collars A on the gudgeons A, by means of their attaching set-screws, allows the tension of the torsional springs A to be varied. By loosening one of the adjusting-screws A or A the sleeves A, together with the pressureplate A can be readily removed from the forked end of the brackets A the sleeves being held in place by the adjusting-screws A and A, which enter countersunk recesses in the tailpieces A The sheet of cardboard is scored in one direction in the usual manner by the action of the bed-roll A and cutters A and is moved by them forward onto the second feed-table B, which is slightly lower than the first feed-table A. The two outer cutters in the first scoring mechanism serve to trim the opposite edges of the cardboard, the cutter on the right cutting off a narrow stripof the cardboard suflicient to straighten its edge and the cutter on the left cutting the cardboard the proper width required for the box, while two intermediate cutters score the cardboard in two parallel lines, upon which the cardboard is to be bent to form the sides of the box. The strips which are cut off from the sides of the cardboard are deflected and carried beneath the table B by means of guide-plates B and 13*, which are attached to the edge of the table B and are represented in perspective View in Figs. 14 and 15. The guide-plates B and B are attached to the edge of the table B and extend partially over the bed-roll A, with their free ends slight-1y raised above the surface of the roll to allow the severed strip of cardboard to pass beneath them.

The guide-plate B upon the right-hand side of the cardboard is provided with the depending sides B B between which the narrow strip of cardboard severed from the sheet passes. Upon the inner sides of the guideplates B and B are the horizontal blades B, which support the side edges of the cardboard between the bed-roll A and the edge of the table 13 and insure its passage upon the table.

The under side of the edge of the table B next the bed-roll A is provided with a triangular rib B, which is notched at B", and the guide-plates B and B are provided with the hooked prongs 13 which extend beneath the triangular rib 13" and are drawn against it by binding-screws 13 the notch B allowing the hooked prong B to be inserted and the guideplate to be locked upon the triangular rib by being moved to the right or left of thenotch l3.

Arranged a short distance above the surface of the table B are a series of horizontal retaining-plates B", extending transversely across the table B parallel with the movement of the cardboard, with one end slightly raised, as at B Fig. 11, to project partially over the scoring-roll A, so the sheet of cardboard as' it passes upon the table 13 will be conducted beneath the retaining-plates B.

The retaining-plates B are provided near their opposite ends with the hollow stems B, which inclose the spindles B depending from the clamping-bars B and B. The retaining-plates B are capable of a slight vertical movement by the hollow stems B" sliding upon the spindles B with which they are connected by means of pins B held in the spindles L and entering slots 13 in the 1101- low stems 13 thereby holding the plates B parallel with the face of the table as they rise and fall upon the spindles B. The spindles B are adjustably connected by the clamping-bars B and B with horizontal rods B", which are supported above the table B by posts at the corners of the table. The clamping-bars are connected at one end by an elastic plate B and their opposite ends are recessed at B to inclose the supporting-rods B".

The spindles B have a fixed collar B bearing against the lower clamping-bar 13" and a nut B held upon the screw-threaded end of the spindle B and bearing against the upper side of the clamping-bar B allowing the bars to be pinched upon the rod B".

The spiral spring B is inserted between the clamping-bars B and B in order to separate them and release the rod B when the nut B is unscrewed.

The retaining-plates B consist of .broad steel plates held at a slight distance above the surface of the table B in order to retain the sheet of cardboard in a horizontal plane when acted upon by the pusherplate B which consists of a thin blade capable of pass ing between the surface of the table and the retaining-plates B The pusher-plate B is attached at one end to a sliding plate B sliding in ways B at the side of the table B and outside of the surface occupied by the cardboard.

The slide B has a depending lug B Fig. 3, projecting beneath the table and pivoted to one end of a lever B which is pivoted at its opposite end to a bracket B and midway its length. to a rod B connecting it with the strap B of an eccentric B which is carried upon a shaft B upon which is mounted the second scoring-roll B so one revolution of the eccentric will impart a complete reciproeating motion forward and backward to the pusher B carrying the sheet of cardboard upon the second feed-table B forward to be engaged-by the second scoring mechanism, comprising the bed-roll B and the rotating cutters B attached to the cutter-bar B The eccentric B is rotated at the proper period of time by a clutching mechanism, which is thrown into action by means of a tripping mechanism actuated by the moving sheet of cardboard and comprising a finger C, Fig. 11, depending from a rocking sleeve 0, supported on one of the rods 13". The sleeve 0 is provided with a radial arm 0 connected by a link 0 with a lever 0 pivoted at C to a fixed support and having its opposite end pivotally connected with a vertical rod 0 extending downward at the end of the machine and connected with the toggle-joint levers O and O connecting the lower end of the rod 0 with the framework of the machine.

The vertical rod 0 is capable of a slight swinging motion on the end of the lever 0 and the toggle-joint connection of the lower end of the rod 0 is for the purpose of causing the lower end of the rod to swing by the straightening of the levers (J' and 0 as hereinafter described.

As the cardboard passes from the firstscoring mechanism onto the second feed-table B its advancing edge strikes against the finger O, rocking the sleeve 0 and raising the connected end of the lever C and as soon as the cardboard passes the finger C the finger is carried back to its normal position and the motion of the lever C is reversed by means of a pull-spring O connecting the end of the lever C with the fixed framework of the machine. The vertical rod G passes through an opening in a horizontal latch C pivoted at one end at C to abracket depending from the under side of the table B. The free end of the latch O is provided on its under side with a Wedge-shaped lug 0, adapted to drop into an annular groove (3 in the hub of the eccentric B and the latch C is pressed downward by a spring 0 inserted between the latch and the table B.

The shaft B upon which the eccentric B turns loosely, carries an attached gear-wheel 0 by which the shaft B is rotated by its engagement with the pinion 0 carried on a main driving-shaft O", which is journaled in brackets at the side of the machine. The hub of the gear-wheel C, on the side next the eccentric B is provided with clutchteeth 0 which are adapted to be engaged by a sliding clutch-bar O ,sliding in a groove in the hub of the eccentric B and arranged to be pushed outward to engage the clutchteeth 0 by a spring 0, The sliding clutchbar 0 is provided with a notch O in proper position to be caught by the pointed end of the wedge-shaped lug C as the eccentric is rotated, thereby causing the sliding clutchbar to be withdrawn from its engagement with the clutch-teeth 0 The vertical rod 0 is provided with a shoulder 0 which is adapted to strike the under side of the latch 0 when the rod C is raised and lift thelatch, withdrawing its wedge-shaped lug C from the annular groove 0 in the hub of the cccentric B thereby allowing the spring 0 to force the sliding clutch-bar 0 into engagement with the clutch-teeth O and causing the rotary motion of the gear 0 to be imparted to the eccentric. Attached to the lower end of the rod 0 and at right angles thereto is an arm G which is pivotally connected with the frame by means of a link C and when the rod 0 is in its lowest position the arm 0 and link 0 are in the position shown in Figs. 3 and 17, with the arm 0 and link C forming an angle with each other; but when the rod 0 is raisedthe arm 0 and link O are lifted,-b ringing the link G into a straight line With the arm 0 as shown in Fig. 18, thereby moving the lower end of the vertical rod 0 to one side and carrying the shoulder C out of engagement with the un der side of the latch C The opening in the latch is large enough to allow the shoulder O to pass thereby, thereby releasing the latch 0 which is instantly forced down by the spring 0 carrying the wedge-shaped lug G into the annular groove 0 in position to engage the notch (3 of the sliding clutch-bar and withdraw-the same from its engagement from the clutch-teeth O thereby stopping the eccentric at the end of one complete revolution.

By the action of the above-described mechanism the movement forward of the sheet of cardboard upon the table B will swing the finger C, and carry the rod C downwardly ICC without engaging the latch C but when the finger C is released by the passage of the cardboard beneath it the spring 0 reverses the movement of the finger O and raises the vertical red C, when the shoulder C of the red 0 hits the latch and lifts it, allowing the sliding clutch-bar to engage the clutchteeth C The driving-shaft C carries the belt-pulley C running loosely thereon, but capable of being connected with the driving-shaft by a clutch mechanism C, of the usual and wellknown form of construction,which is thrown into and out of engagement by means of a shipping-lever 0 links C and bell-crank lever C (Shown by broken lines in Fig. l beneath the table A in convenient position to be operated by the attendant.) The first scoring-roll A is rotated from the driving-shaft O by m cans of the beveled gears C CF, Projecting from the lower side of the pusher-slide 13 is a lug D, which carries a rod D, sliding through the fixed lug D attached to the under side of the table B and carrying an adjustable collar Dibetween which and the fixed lug D I insert a compression-spring D which acts as a buffer to check the momentum as the pusher B and B is pushed outward.

Supported a short distance above the upper surface of the table 13 are the parallel rods E E, upon which are placed sliding sleeves E E, adj ustabl y attached by set-screws to the rod E, and supported by the sleeves E E is a rod E to which the device for stopping the movement of the cardboard on the table 13 is adjustably attached, said step device consisting of a sleeve F, having a spline connection with the rod E and held from longitudinal movement on the rod and in any desired position by means of a set-screw F. The sleeve F is provided on opposite sides with the gudgeons E 1 and on the gudgeon F is suspended the swinging frame F provided with holes F F in its lower end, in which are placed the sliding pins F E, which are pressed downward by spiral springs F F and the lower ends of the pins F carry a pin F upon which the roll F turns. The roll. F" is slightlybeveled, and one edge is held in contact with the upper surface of the table B by the pressure of the spiral springs F so the side F of the roll next the first scoring mechanism will serve as a stop for the advancing edge of the cardboard. Upon the gudgeon F is pivoted a swinging frame G, slotted at its lower end at G to receive a swinging block G pivoted at G with its axis at right angles with the axis of the swinging frame 1. The lower end of the swinging block G carries a stud G upon which is journaled a beveled roll G presenting a sharp corner G6 to the surface of the table B. As the sheet of cardboard is moved against the stop-roll Win the direction of the arrow G Fig. 7, the retaining-roll G5 is raised by the swinging of the block G allowing the cardboard to pass beneath the retaining-roll, allowing the sharp corner G6 to rest upon the upper surface of the cardboard and byits engagement with the cardboard prevent its rcbound or backward movement. As the cardboard is pushed toward the second scoring mechanism by the pusher-plate B the forward end of the cardboard is in contact with the stop-roll F and its upper surface is engaged by the sharp corner G of the retaining-roll G and both the stop-roll F and the retaining-roll G are free to move in the direction of the moving cardboard by the rotation of their swinging frames F and G upon their supporting-gudgeons. By this means I avoid any friction between the edge of the cardboard and the side of the retaining-roll and prevent any displacement of the cardboard owing to the movement of an irregular edge against the side of the stop-roll F", in order to allow the pushing-plate B to pass under the rolls carried by the swing-frame, if required, but if not then to allow the frame to swing as the sheet of cardboard is moved along by the forward motion of the pushingplate and prevent any undue friction or drag upon the sheet of cardboard.

As it bears against the side of the roll F, the stop device above described can be adjusted to any position upon the surface of the second feed-table B by sliding the sleeves E E on the parallel rods E Eand by moving the sleeve F on the cross-rod E The rotating cutters employed in each of the scoring mechanisms are alike and are represented in Figs. 8, 9, and 10.

The cutters consist of a disk II, provided with a knife-edge turning upon a stud II, held in a slotted yoke H which is pivoted at one end to one end of a link 11 the opposite end of the link being pivoted to a frame II", which is adj ustably attached by a screw II to the cutter-bar. By connecting the yoke to the frame by the link I1 I cause the end of the yoke to move in the arc of a circle as it is moved down, said are nearly coinciding with astraightline. The opposite end of the yoke H slides in ways in the frame II", and the frame H carries a set-screw ll, provided atits inner end with a neck 11 and head 11 engaging a T-slot in the end of the yoke H by which the yoke is moved up or down in its ways by the screw H. The end of the yoke sliding in the ways of the frame 11 is held in position by a plate H, attached to the frame H by a screw H and between the plate II" and end of the yoke I interpose a spring 11 in order to take up any lost motion between the yoke and its ways. The spring H also allows a slight movement of the yoke as it is acted upon by the link 11'.

One of the gudgeons A of the pressureplate A is squared at its outer end, as at I, to receive a plate J, which is held upon the squared end of the gudgeon by a screw J; so the plate J will turn with the gudgeon. The plate J carries a pin J which enters a slot J in the tailpiece A in order to limit the downward movement of the edge A of the pressure-plate as the cardboard passes beneath it.
