Application led July 29, 1912.

To all 'whom it may concern Be it knownjthat I, FRANK M. JosLIN, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Machines for Scoring and Dieing Box-Blanks, of which the following is a specification.

This invention relates to machines for making paper box blanks and more particularly to the scoring and dieing mechanism.

The objects of the invention are to provide a scoring and dieing mechanism which is especially adapted to make box blanks from a heavy continuously moving web without interrupting the movement of the web.

The invention is especially applicable for use in connection with continuous machines for forming a web and printing the same, such as is shown in application No.712,130 filed the 29th day of July, 1912, by Horace lnman and myself as joint inventors.

The novel features of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which,

Figure 1 is a side'elevation of the machine; Fig. 2 is a planof the same; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a bottom plan view of one of the male dies; Fig. 5 is a bottom plan view of another of the male dies; and Fig. 6 is a plan of the box blank.

Referring to the drawings, a indicates a web of paper which `may be fed into the machine by any suitable feeding mechanism. The frame of themachine, 10, is supported by means of the legs 11 and carrieson its lower side the bearing brackets 12 and 13, the brackets 12 supporting a shaft 14 and the'brackets 13 supporting a shaft 15.k Secured to the frame in any suitable manner, preferably near its ends, are the upri ht guides 16, these guides being connecte together at their tops by a frame 17.

A cross head 18v is arranged lon itudinally of the machine at one side t ereof and provided with sleeves 19 which engage two of the` rods 16 whereby the cross headis arran ed to slide in a vertical plane. A

. cross ead 20 is arranged on the opposite Specification of Letters Patent.

side of the machine and provided with sleeves 21 engaging two of the guides 16.

At the ends of the shafts 14 and 15 are crank disks 22 having crank pins 23.` The cross heads 18 and 20 are provided with the wrist pins 24 and 25 respectively, these pins being connected with the pins 23 by the connecting rods 24. The connecting rods 26 are preferably formed in two sections, connected together by means of turnbuckles 27 which have screw-threaded engagement with the sections of the rods in the usual manner and are held in any adjusted position by means of the lock-nuts 28. The shaft 14 is provided with a sprocket wheel 29 and the shaft 15 is provided with a sprocket wheel 30 of the same size as the sprocket wheel 29 and connected with the latter by means of a driving chain 31, whereby the shafts will rotate in unison. From the drawings it will be seen that as the shafts 14 and 15 rotate the cross heads 18 and 20 will be moved up and down on the upright guides 16.

Arranged on the upper side of the frame 10 are longitudinally extending tracks 32 on which run the traction wheels 33 of the carriages 34, these carriages supporting the bed plates 35. At the ends of the bed plates 35 are arranged the upright guides 36 which pass through suitable openings in the die plates 37 and serve as guides for the latter. Each of the die plates 37 has arranged at the ends thereof trunnions on which are mounted the rollers 38, these rollers being confined in suitable grooves 39 on the inner face of the cross heads 18 and 20. The bed plates 35 are connected together by means ofthe straps 40 which extend along the ends of the bed plates and are connected thereto by means'of bolts 41, these bolts being movable in slots 42 and thereby permitting the bed plates to be adjusted longitudinally of the machine.y Each of the straps 40 is provided with a wrist pin 43 and by the arrangement just described the carriages 34 and the bed plates 35 are so connected that they will move together longitudinally of thejmachine.

For the purpose of movin the carriages 34 and the bed plates 35 bac and forth on the tracks 32 I have provided a shaft 44 which is mounted in bearing brackets 45 secured to the frame 1'0. The shaft 44 has arranged on the ends thereof the wheels 46 which carry the crank pins 47, the latter being adjustable radially in suitable slots 48. T he shaft 44 may be driven in any suitable manner, as by means of a'- power cham en` gaging the sprocket wheel 49. The wrist pins 43 are1 connected with the cranks pins 47 by means of the connecting rods 50. By this construction it will be seen that the rotation of the wheels 46 will move the carriages 34back and forth in the desired'manner, and the speed of the shaft 44 is preferably arranged so that the velocity of the carriages 34 when the crank pins 47'are moving directly above or below the shaft 44 will be substantially the same as the velocity of the web a. i

The die plates 37 carry suitable cutting and scoring dies which coperate wlth corresponding dies carried by the bed plates 35 and the downward movement of the d1e plates 37 is so timed that the dies engage the web .at the time that they aremovingin the direction of movement of the web and at substantially the same velocity as that of the web. The die plates 37 ,v as will be readily understood, are moved back and forth longitudinally of the machine by means of the upright'guides 36, carried by the bed plates 35 and owing to the fact that l all of the die plates are connected with the cross heads 18 and 2O it will be seen that they will be caused to engage the web simultaneously, as the cross heads are reciprocated vertically by the connecting rods 26. The dieing and scoring is therefore edected by means of dies which are moving with the web and at the same speed as the web and therefore it is not necessary, as has been heretofore the case with scoring and dieing mechanism, to interrupt the forward move- ,ment of the web. IThis feature, is of great practical importance in machines which handle webs of thick material which is unwound from rolls of immense weight, as it is utterly impracticable to stop and start the rolls by an intermittent forward feed. By adjusting the crank pins 47 in the slots 48 the stroke of the carriages 34 may be regulated and by means vof the slots 42 the positions of the dies may be adjusted for v the purpose of producing boxes of various shapes and sizes.

The web a moves through the machine in the direction of the arrow and the set of dies at the entrance end of the machine are those which cut the openings and make the cross score y and also the cut a by which the blank is severed from the web, as clearly shown in Fig. 6. The male die of the setv at the entrance end of the machine is shown in Fig. 5. The male dies for making the cuts as and the cross scores y are shown in Fig. 4 and are carried by the succeeding carriages 34. y

At the delivery end of the machine is arranged a pair of upright brackets 51 which support a pair of feed rollers 52 and 53, these rollers being operatively connected by means of a pair of gears 55, driven by a sprocket wheelv 56 anda chain 57 from a sprocket 5 8 on the shaft 15. flhe feed rolls 52 and 53 are preferably arranged to have a peripheral velocity exceeding the velocity of the web so that when the blank has been severed from the web these rolls will quickly draw the blank from the machine.

llt will be understood by those skilled in the art that various changes may be made in the details of the mechanism within the scope of the claims and therefore ll do not wish to be limited to the precise details which l have shown and described.
