UNITED STATES PATENT OFFICE.

FRED R. HARRIS, OF NEVVYORK, N. Y., ASSIGNOR TO THE AMERICAN TOBAOOOCOMPANY, OF NEW YORK, N. Y.. A CORPORATION OF NEW JERSEY.

v PRINTING AND BRONZING MACHINE.

To all whmit it may concern.

Be it known that I, FRED R; HARRIS, a citizen of the United States, residing at New York city, county'of New York,-and State of. New York, have'invented certain new andous strip of paper or other suitable material matter for forming a succession of labels, wrappers, or other articles by printing a design on successive portions of the strip with size or adhesive material and then applying bronze-powder or other suitable metallic or colored powder'to the strip, so that the powder will adhere to the size and show on the strip in the design in which the size was printed on the strip.

The invention aims generally to provide an improved machine of this class, and especially to provide an improved bronzing mechanism, wherebythe bronze will be properly and evenly applied to the sized portions of the strip and cleaned from the unsized portions thereof, and to provide an improved winding mechanism for rewinding the printed strip into a roll.

To these ends the invention consists in various arrangements and combinations of parts, as hereinafter particularly pointed out in the claims.

A full understanding of the invention can best be given by a detailed description of a preferred construction embodying the various features thereof, and such a description will now be given in connection with the accompanying drawings, showing such apre= ferred construction.

In said drawings, Figures 1 and 1 show such a preferred construction in side elevation. Figs. 2 and 2 show the machine in plan view. Fig. 3 is an enlarged detail side view looking in'the direction of the arrow 3 on Fig. 2. Fig. 4 is a broken plan view of parts shown in Fig. 3.

view of the device for guiding the strip to the printing-cylinder looking in the direction of the arrow 7 of Fig. 8. Fi 8 is a longitudinal sectional view of suc Fig. 9 is a longitudinal sectional view of the strip-guiding device for guiding the strip as it leaves the rinting-cylinder. Figs. 10, 11, and 1,2 are en arged detail views of parts hereinafter described.

The machine will be described by following the course through the machine of the strip of paper or other material to be printed. The strip or web of paper w is preferably drawn from a roll supported in any suitable manner by arms 10, from which roll the strip is drawn by a pair of continuously-driven feed-rolls 11, to which it is guided by asuitable guide 12. Beyond the continuouslydriven feed-rolls 11 the strip passes between guiding device.

a pair of intermittently-driven feed-rolls 13,

a take-up device, such as therising-and-falling roller 14, being provided between the feed-rolls 11 and 13. From the intermittently-rotating feed-rolls 13 the strippasses to the printing mechanism and thence between a pair of intermittently-rotating feed-rolls 15, driven in unison with the feedrolls 13.

Any suitable printing mechanism might be employed in connection with other parts of the invention for printing successive labels or other designs on the strip with size or suitable adhesive material for holding the bronze.

The printing mechanism shown is adapted for printing, on successive lengths of a strip and comprises a continuously rotating printing-cylinder 20, the circumference of which is not equal to or an even multiple of the length of such successive lengths of the.

strip and a cooperating impression-cylinder 21. The printing and impression cylinders are driven at a surface speed equal to the surface speed of the feeding- rolls 13 and 15, and

the printing-cylinder is of a size such that blanks. Asshownflt is equal to the length of five blanks. The movements of the intermittent feed- rolls 13 and 15 are timed, so that the strip will be advanced by such rolls during the time that the printing-surface a of the printing-cylinder is coacting with the impression-cylinder 21 and the strip will be held stationary during, the time that the cutaway portion b of the printing-cylinder is opposite the impression-roll. The first label or other design printed on the strip at each rotation of the printing-cylinder may thus be spaced from the last label or other design rinted by the previous rotation of the printmg-cylinder, exactly the same as the labels printed by intermediate portions of thesurfaceta.

The size may be applied to the printingsurfaces by any suitable means. 1 (Not shown.) The printing-cylinder is preferably provided with punches c for forming a registering perforation in each of the printed lengths of the strip as printed, as is customary in similar machines.

The printing-cylinders and feeding-rolls may be driven in any suitable manner. As shown, the printing and impression cylinders are geared to rotate together and are driven from agear22 on the main drivingshaft 23 by means of intermediate gears 24, as indicated by dotted lines in Fig. 1. The

feeding-rolls, as shown, are driven by a continuously-rotating shaft 25, which is driven .from the shaft of the printing cylinder through a shaft 26, carrying at one end a beveled gear-meshing with a beveled gear 27 on the shaft of the printing-cylinder and at the other end a beveled gear meshing with a beveled gear 28 on the shaft 25. The feeding-rolls 11 are geared to turn together and are,driven from the shaft 25 by means ofa sprocket chain 29, turning on sprocketwheels on the shaft 25 and on the shaft of one of the rolls 11. feeding-rolls 13 are geared to turn together and are driven from the shaft 25 by means of a stop-gear comprising a mutilated gear 30 on the shaft 25, meshing with a pinion 31 on the shaft of the lower roll 13, the mutilated gear being provided with a concentric flange or face 32 for engaging the concave face of a block 33, secured to the pinion 31 for holding the pinion and rolls 13 against rotation, while the toothless portion ofthe gear 30 is opposite the pinion. The intermittently-rotating feeding-rolls 15 are also geared to rotate together and are driven from the rolls 13 by means of a rotary shaft 34, which has a bev eled gear at one end meshing with a beveled gear 35 on the shaft of one of the rolls -13 and at the other end a beveled gear meshing with. a beveled gear 36 on a shaft which also carries a spur-gear 37, meshing with a gear on one of the rolls 15 for driving said rolls.

Means are preferably provided for guiding The intermittently-rotating the strip as it advances to the printing device for the purpose of positioning the strip relatively to the printing-cylinder to insure a uniform posit on of the printed matter with respect to one edge of the strip even though the strip may vary slightly inwidth. For this purpose there is preferably provided such a guiding device as is shown in detail in Figs. 8 and 9, such device comprising a guideway formed of a plate 40, having side flanges 41. -42, the space between whlch is slightly greater than the width of the strip. At one side of the guideway and slightly In advance of the forward edge thereof is mounted a bearing-roll 43 for engaging one edge of the strip. as it advances into the guideway to press the other edge of the strip against the guiding-flange 41. Such bearingroll 43 may be mounted in any suitable manner to secure the desired result; but I have found a substantially rigid mounting such as shown to answer well, the roll bein preferably adjustable, as by means of a tl iumbscrew 44, for hearing with greater or less pressure against the edge of the strip or to accommodate strips of slightly-varying widths. A pivoted bearing-plate 45 is preferably provided for holding the plate against the bottom of the guideway, said plate preferably lying in an inclined position and ex tending forward from its point of support, the'weight of the plate being usually suflicient to accomplish the desired purpose. There is also preferably provided a guiding and stripping device for uiding the strip asit leaves the printing-cy inder and for preventing the strip from adhering to the print ing-surface and being thereby carried -upward about the printing-cylinder. For this purpose a device such as shown in detail in Fig. 9 is preferably provided, such device comprising a guideway 47 having side flanges 48 and a bearing-spring 49, carried by a rod 50, the end of which rod is supported in downwardly and rearwardly inclined slots 51 in the guide-flanges 48, such bearing-spring being preferably providedwith a small bearing-roll 52 atits forward end to run against the surface of the strip and being formed so that its rearward end will also hear lightly against the strip. Such guiding device is located, as shown in Figs. 1 and 2, so that the bearing-roll 52 will engage the-strip just after it passes the line of pressure between the printing-cylinder and the impression-cylinder, the bearing-roll thus acting as a stripping-roll to prevent the strip from adhering to the printing-surfaces.

From the feeding-rolls 15 the strip is advanced to the bronzing mechanism. Such mechanism comprises means for applying the bronze-powder to the strip and means for distributing the powder so as to cause an even layer of thepowder to adhere to the parts of the strip to which the size has been ap- ICC , senses plied by the printi' mechanism. The ap plying means may. e of any suitable construction, the preferred means shown comprising a c'QntainingI-chamber -55for the ronze-powder, wh chamber'niay be of cylindrical form, as shown, and a rotary brush 56, mounted in'the containing-chamber so that a portion thereof extends through an opening in the lower side of the chamber. Adjustable plates 57 and 58 are provided at either side of the brush-opening for controlling the amount of owder to be delivered by the brush. The rush-roll 56 is rotated slowly and preferably intermittently, and in the operation of the machine the portion of the brush extending from the containingchamber 55 moves in contact with the surface of the strip a; as the latter is advanced beneath it, the strip moving over a su porting-plate 59, which extends beneat the brush-roll and beneath the distributing devices, to which the strip advances after having had the bronze-powder applied to its upin accordance with the comprise a plurality of distributing-rolls, as'

per surface.

The distributing devices when constructed present invention 60 61 62 63, extending transverse y of the direction of movement-of the strip and rotated to rub the surface of the stnp, preferably a ainst the direction of movement thereof, an two of said rolls 61 and 62 having their axes o positely inclined slightly in the direction of movement of the strip. I thus provide a series of distributing-rolls having relatively inclined axes, and the axes of two of said rolls being oppositelyinclined to the direction of movement of the strip, and by the use of distributing-rolls so arranged I am enabled to secure an even and uniform distribution of the bronze powder over the portions ofthe strip to which the size has been applied. The distributing-rolls may be provided with any suitable rubbing-surface for operating with: a suitable light yielding pressure against the surface of the strip.

The distributing-rolls are shown as driven from a shaft 65, which shaft is continuously driven from the shaft 23 by means of a belt 66, turnin on beltulleys on the two shafts. The distri uting-rolls '60 and 63 are driven from the shaft 65 by means of belts 67 and 68, respectively, and the distributing-rolls 61 and 62 are driven from the shaft 65 by means of a belt 69, which runs over a pulley 70 on the shaft of the roll 61, thence under an idle pulley 71, thence over a pulley 72 on the shaft of the roll 62, and thence about a pulley on the shaft 65. The applying-roll 56 is given an intermittent rotary movement by means of a pawl 73, carried by an oscillating arm 74, pivoted to swing concentrically with the roll 56, which pawl en ages a ratchetwheel 75, fast on the shaft 0 said roll. The arm 74 is oscillated by means of'a rod 7 6, ex-

ten

pawl 73 to vary the amount of movement of the roll 56 for each throw of the pawl.

The bronze ap lying and distributing devices are inclosed in a suitable casing 78 to prevent the powder flying out in the air and or collecting the powder which falls from the strip and from the distributing-rollers. The containing-chamber 55 is preferably adjustable vertically, as by means of set-nuts 79, so as to cause the applying-r0ll 56 to bear with greater or less pressure against the surface of the strip, as may be necessary or desirable. The distributing-rolls are also preferably 'ournaled in adjustable bearings, as shown.

he strip is drawn past the bronze a plying and distributin devices by means ofa pair of mtermittently-rotating feeding-rolls 80, said rolls being shown as geared together and driven in time with and at the same surface speed as the feeding- rolls 13 and 15 by means of a belt 81 from the shaft of one of the feeding-rolls 15. After leavin the feeding-mils the strip is drawn past the cleaning means for removing the surplus bronze powder from its surface and is then in the machine shown rewound into a roll for convenience and trans ortation. The strip is preferably allowe to run slack between the feeding-rolls 80 and the cleaning mechanism and preferably on leaving the feeding-rolls 8O dro s into a suitable receptacle 85, in which t e slack may collect and from which the strip is caused to move past the cleaning mechanism.

Any suitable mechanism may be employed for cleaning the surplus powder from the strip. The preferred means shown for this purpose, however, which forms a part of the invention, comprises a rotary drum 90, about which are arranged a plurality of cleaningrolls 91, 92, and 93, said rolls having cleaning or dusting surfaces of any suitable material, such as a suitable fur, and being positioned to brush the surface of the strip as the latter is advanced about the drum. Such cleaningrolls are preferably rotated to brush the surface of the stri in the direction opposite to the direction 0 movement of the strip on the drum, as indicated by arrows in Fig. 1. receptacle 94 is provided for each of'the cleaning-rolls for receiving the owder brushed from the strip, such receptac e being provided with edges 95 for scraping or combing the powder from the rolls and being preferably adjustably mounted, as indicated in the drawings. Any suitable means may be provided for causing the drum 90 to rotate and the IIO strip to advance about the drum and past the cleaning-rolls. Preferably, however, the ro- 7 ably tating force is not applied directly to the drum; but the drum is caused to rotate with the strip by pulling means actingon the strip after it leaves the drum. In the construction shown the wind-up roll acts as such a pulling means.

The drum 90 and cleaning-rolls are preferably mounted within a casing 96, and a guide 97, having side guiding-flanges and a. pivoted plate 98 for hearing on the top of the strip to prevent it from rising between the flanges, is provided for guiding the strip as it advances to the drum 90, an idle roll 99 also being preferably provided for bearing on the strip between the guide 97 and the drum. Laterally-adjustable edge-guides 100 are also preferably provided for engaging the edges of the strip as it advances from the drum 90 to the wind-u roll. The cleaning-rolls are shown as driven from the shaft by means of a belt 101 turning on a belt-pulley 102 on the shaft 65 and a belt-pulley 103 on the shaft of the cleaning-roll 92, the rolls 91 and 93 being driven from the shaft of the roll 92 by means of belts 1.04 and 105, respectively.

Any suitable rewinding mechanism may be employed. Preferably, however, I provide a shaft 110 for receiving and rotating a core 111, on which the stri is to be wound into a roll, and such shaft is rotated as from the shaft 65 by means of a belt 112, running on belt- pulleys 113 and 114 on the shaft 65 and said shaft 110, respectively, at a speed sufficient to take up the strip as fast as it is delivered from the printing and bronzing mechanisms even at the starting of a new rollthat is, when the roll being wound is only substantially the size of the core 111. The strip-will thus be rewound faster than it is delivered from the printing and bronzingmechanisms, and means are provided for stopping the rotation of the Wind-up shaft whenever the slack between the bronzing and the cleaning -mechanisms has been taken up. T 0 permit the stopping and starting of the rotation of the shaft 11 0 it is preferably driven through a suitable clutch connecting it with a constantly-rotating member. As shown, the hub of the belt-pulley 114 is mounted to rotate freely on the shaft 110' and may be connected thereto by means of a clutch-sleeve 115, splined to slide on said shaft, and which clutchsleeve may be moved into and out of position to engage the hub of the pulley 114' by means of a lever 116. Means are preferrovided for automatically throwing said 0 utch to disconnect the shaftfrom the pulley 114 when the slack of the strip between the'bronzingmechanism and the cleaning mechanism has been taken up. For this purpose a spring 120 tends to throw the lever 116 to disconnect the clutch-sleeve from the hub of the pulley, such unclutching movement being prevented during the time the shaft is to rotate by a latch 121, which engages the-lever to hold it against the pressure of the spring 120, which latch is connected b a link 122 to an arm 123, carried by a shaft 124, which shaft also carries arms 125,between which a rod. 126 extends through the receptacle 85, so that when the slack of the strip which lies beneath the rod 126 is taken up the loop of the strip will engage and raise the rod 126, thereby moving the arms 125 upward, rocking the shaft 124 and drawing the latch 121 back away from the lever 116, thereby releasing the lever and permitting it to move outward under action of the spring 120 to unclutch the shaft 110 from the pulley 11.4. By this arrangement when the lever 116 is thrown tostart the wind-up shaft rotating the strip will be drawn from the rece tacle about the drum and wound on tl fe core 1 1 1 and this operation will continue until the slack of the strip between the bronzing and the feeding mechanisms is so far taken up as to raise the rod 126, and thereb effect the unclutching of the wind-up sha t from the pulley 1 14. The wind-up shaft will then remain stationary until the clutch-lever 116 is again thrown inward to cause the shaft to, again rotate. Meanwhile the operation of the printing and bronzing mechanisms continuing the printed strip will be fed into the receptacle 85 and accumulate therein until the cleaning and wind-up mechanisms are again put into operation.

A tension or brake device is preferably provided for preventing the momentum of the drum 90 causing it to continue rotating after the sto ping of the wind-up shaft 110, such brake evice being preferably an adjustable friction-clamp 130, engaging the end of the drum-shaft.
