MACHINE FOR CUTTING, SCORING, AND EMBOSSING PAPER FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 641,215, dated January 9, 1900.

Application filed March 31, 1899.

To all whom it may concern.-

Be it known that I, FRANCIS MEISEL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Machines for Cutting, Scoring, and Embossing Paperfor Boxes, &c., of which the following is a specification.

My invention has for its object to improve the construction and increase the product of machines for cutting, scoring, and embossing paper for boxes and other purposes; and my invention consists in the several novel features of construction and combinations of parts hereinafter described, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of one side of my improved machine. Fig. 2 is anelevation of the opposite side of the same. Fig. 3 is a rear end elevation of the machine. Fig. 4 is an enlarged rear elevation showing the gripper-operating mechanism and the mechanism for actuating the swinging table. Fig. 5 is a detail, partly in section, showing a portion of the endless carrier-chain, one of its grippers, the gripperbar which actuates the grippers, its supporting-bar, and thefront end of the swinging sheet-supporting table. Fig. 6 is a detail of one of the carrier-chain-locking devices. Fig. 7 is a detail of the carrier-chain-operating mechanism. Fig. 8 is a plan of the sheetsupporting table and the ends of the grippers.

Referringto the drawings, Arepresents the framework of the machine, in suitable bearings in which are j ourn aled two parallel shafts b c, on each of which are fixed two sprocketwheels cl,which support endless carrier-chains B B, one on each side of the machine. The pins 6, Figs. 1 and 4, which connect the links of said chains, engage the notches of the sprocket-wheels (1, whereby the chains are caused to travel a the same speed and with :LpOSllilVO motion in the desired direction. The chains B are provided on their outer sides with antifriction-rolls 25, placed at suitable intervals, said rolls running on guide-rails 26 at the topof the machine and in guide-grooves 27 in the framework, as shown in Figs. 3 and 4.. These guide-rails and guide-grooves support, respectively, the upper and lower por- Serial No. 711,229. (No model.)

tions of the chains and prevent them from sagging in case they should become slack from wear or other cause. 7

C is the driving-shaft, which carries a driving-pulley D, to a crank-pin on which is pivoted a rack-bar E, which slides in a guide or casing f and meshes with a gear loosely mounted on a transverse shaft 72, to which gear is secured a disk 28, carrying a pawl 29, adapted to engage a notch or tooth in a disk 21, Fig. 7, fast on the shaft h. A gear 30, also fast on the shaft h, meshes with an intermediate gear 31, the latter meshing with a gear 32 on the sprocket-wheel shaft 0, an intermittent movement of the carrier-chain being thus produced as the driving-pulley is rotated.

The sheets of paper 17 to be cut, scored, or-

embossed to form blanks for paper boxes or for other purposes are piled on a table G at the front of the machine and are fed forward singly by hand onto a table 33, pivoted at its outer end at 3i and provided with a side gage 1S and at its inner end with gages 35, which form stops against which the front edge of the sheet is placed by the operator, ready to be seized by one of the several sets of grippers 1;, with which the bars extending between the chains B are provided, said chains at each forward movement traveling a distance equal to that between two adjacent sets of grippers. The gages 35 extend inward beyond the grippers, so that the leading edge of the sheet when pushed forward against said gages may be in a proper position to be seized by said grippers while the chains are at rest. The tilting table 33 is raised from its lowest position, as shown'in Fig. 2, to its highest position, as shown in Fig. 5, before the sheet is fed onto it by the operator to insure the leading edge of the sheet being pushed between the jaws of the grippers 2', and just before the chains commence to move said table is lowered into the position shown in Fig. 2 to move the gages out of theway of the sheet and allow it to pass without obstruction to the cutting, scoring, or embossing mechanism, to be hereinafter described. The table 33 is swung upward on its pivot and lowered at the proper times by means of a toggle k, to one arm of which is pivoted a rod 38, the opposite end of which is pivoted to a lever 39, carrying a roll 40, which is acted upon by a cam 41 on the main shaft C.

At each forward movement of the chains B a sheet 17 is carried onto a vertically-reciprocating member H, which cooperates with a stationary member I, placed thereover, said member H being provided,as may be required, with cutting-knives, scoring-rules, or embossing-dies properly disposed to cut from the sheet, score, or emboss box-blanks or other articles. If preferred, the cutting-knives, scoring-rules, andembossing-dies may be secured to the stationary member I instead of to the member 1-1. These members 11 I may be generically termed impression members.

Immediately under the reciprocating member H on each side are placed a pair of toggles J, connected by a horizontal bar 42. To one of the toggles J is pivoted a slotted connecting-piece K, which slides on the shaft O. Within this connecting-piece K is placed the main cam 44, Fig. 3, which is secured to the shaft 0 and acts on the cam-roll 45 to straighten out the toggles, and thereby raise the member H. Outside the connecting-piece K are secured on the shaft 0 cams 46, which act on rolls 47, mounted on a shaft at the lower endof the connecting-piece K, and serve to open .the toggles and return the parts to their normal positions. The cams are so formed and timed as to permit the member H to remain at rest while the sheet is being drawn thereover and held by the grippers 11. The grippers do not release their hold upon the sheet during the time that it is being cut, scored, or embossed, and as soon as the member H has come to rest after its descent the carrier-' chains are again set in motion, thereby causing the sheet which has been cut, scored, or embossed to be carried over a table L, when it is released by the grippers and drops onto the pile on said table L, as shown in Fig. 2.

I will now describe the construction of the grippers and the manner in which each set is operated to seize the front end of the sheet and afterward release the same to permit it to drop onto the table L after being carried thereover by the movement of the carrierchains B, reference being had particularly to Figs. 1, 4, and 5. Between two opposite links H n of the chains B B is secured a transverse bar 19, to which are secured a series of grippers 2', (shown enlarged in Fig. 5,) each of which is composed of a stationary jaw 48 and a movable jaw 49, normally kept apart, preferably by a spring 50 placed between them, the vertical portion of the stationary jaw and the plate to which the movable jaw 49 is pivoted at 51 being secured to the bar 19 by screws 52. The grippers are operated by a longitudinally-sliding bar q, Figs. 3, 4, and 5, which bears against the movable jaws 49, as shown in Fig. 5, said bar q being provided with inclined slots 53, through which pass screws 54,

by which it is fastened to the bar 19 in such manner that when it is moved in the direction of the arrow, Fig. 4, it will, by the action of the inclined slots on the stationary screws 54, be moved on the bar 19, thus closing the jaws 49 against the action of the springs 50 and causing the grippers to seize the sheet previously pushed against the gages by the operator. On the return movement of the bar q the inclined slots cause it to be drawn back to the position shown in Figs. 3, 4, and 5, which permits the springs 50 to open the grippers and release the sheet.

The bar q is slid first in the direction to close the grippers and then in the opposite direction to open the same in the following manner: On the shaft 0 is a cam 60, Figs. 1 and 4, which acts 011 a roll 61 on a lever 62, to which is pivoted a rod 63, the opposite end of which is pivoted to a bell-crank 64, secured to a short shaft 65. The upper arm of the bell-crank 64 bears against a projection 69 on the sliding bar g, which is thus moved at the proper time to cause it to close the grippers upon the sheet. To the shaft 65 is secured a toothed segment 66, meshing with another toothed segment 67 on a shaft 68, extending to the rear or delivery end of the machine. On the shaft 68, at the rear end of the machine, is an arm 70, which bears against the side of the projection 69 opposite to that in contact with the bell-crank 64 and moves the bar q in a direction contrary to the arrow, thus opening the grippers and releasing the sheet, which then drops onto the table L be neath, the grippers remaining open until they are again brought around to the front of the machine ready to take a fresh sheet. In the machine here represented the carrier-chains are provided with six sets of grippers arranged at equal distances apart, but any suitable number of sets may be employed to meet the requirements of the case. When the carrier-chains B stop, the gripper-operating bars q of the front grippers to be closed on the sheet and the rear ones to be opened are always in such positions that their projections 69 can be acted upon by the arm of the bellcrank 64 and the arm 70 of the shaft 68.

As soon as the carrier-chains come to a stop they are locked to insure the several sets of grippers being in their proper positions with respect to the gages, the cutting, scoring, and embossing mechanism, and the delivery-table by means of a bar r, sliding in a Vertical guide on the framework and having its upper end shaped to engage amotch 73, Fig. 7, in the hub of the gear 30, whiE-E is thus held stationary when the bar '1" is within the said notgh. The lower end of this bar r is connected My means of a link 74 with a bell-crank lever 1 5, fast on a transverse rock-shaft s and having pivoted to its short arm a rod 76, also pivoted to a lever 77, fulcrumed at 79 and carrying a roll '78, which is acted on by a cam 80 on the shaft 0, said cam being timed to raise thelock- IIO ing-bar r and cause its upper end to engage the notch at the instant that the movement of the chains 13 is arrested.

On account of the lost motion between the chainlinks, sprocket-wheels, and gears I employ an auxiliary locking device which causes the chains to be held positively at a predetermined point for the purpose of bringing every sheet into precisely the same position at the termination of each movement of said chains, thereby insuring perfect register. This locking device consists of two bars S S, one for each chain and each provided at its upper end with a semicircular notch, Fig. 6, for engagement with the pins 6, which connect the V links of the carrier-chains, said bars S sliding in vertical guides on the framework A and being connected by means of bars 82 with arms 83, fast on the rock-shaft s, which latter is actuated by the cam 80, as before described.

In order to diminish the speed of the carrier-chains j ust before the termination of their movement, and thus prevent them from being carried by their own momentum and that of their actuating mechanism beyond the desired point, which would interfere with the proper operation of the locking devices, I employ a brake consisting of a friction-strap w, encircling the hub of the gear 32 and connected at its upper end by means of a link 8% to a bellcrank 85, the latter being connected by a rod 86 to a lever 87, fulcrumed at 88 and carrying a roll 89, acted upon by a cam 90, Figs. 3 and 4:, on the shaft 0, which is properly timed to apply the brake just before the termination of each intermittent movement of the chains.

It is obvious that the above-described machine can be easily adapted for printing by simply substituting a printing-form for the cutting, scoring, or embossing dies and employing the proper inking mechanism in connection therewith.
