like, of labels that have been previously passed through a press and been prepared for the bronze by an impression of sizing as a basis of adhesion.

To those familiar with the art to which this invention appertains, it is well known that heretofore in the trade the labels have been passed by hand or by automatic conveyors to a bronzing machine distinct and more orless remote fro-m the multi-color or other printing press of the bed and cylinder type, with the result that the labels are at least partially dry when received in the bronzing machine, thereby preventing the bronze powder from properly adhering thereto while at the same time, either the services-of attendants are required in transferring the labels from the press to the bronzing apparatus, or a very expensive and complicated system of mechanical transfer is employed which not only is liable to get out of order, but is troublesome to maintain. With a knowledge of these conditions as they exist today in the trade thus far developed, the primary object of our invention is to provide a bronzing attachment for bed and cylinder multicolor printing presses which is so constructed and arranged that it may receive the sheets directly from the cylinder of the press and effectively apply bronze immediately after they have been prepared by the sizing, so that the sheets will be treated before the sizing shall have had time to dry to any extent.

Another object of our invention is an improved bro-nzing attachment of the character set forth which will be of simple and durable construction, easy to maintain and not liable to get out of order, capable of being being applied directly to or at the cylinder of the press, is so arranged that the devices which rub the sheet to cause the effective adhesion of the bronze powder are automatically backed away from the cylinder at predetermined intervals and in predetermined order, so that they Will be entirely out of the way of the gripping fingers and adjoining open parts of the cylinder when the fingers and such parts are passing said devices. the rubbing devices being then automatically and in predetermined order moved forwardly into operative position where they will contact with the passing sheet. And the invention also aims to generally improve and simplify bronzing apparatus so as to effect economies in the trade.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists essen tially in a bronzing attachment for multicolor printing presses of the cylinder and bed type, which may be readily secured to a press close up to the cylinder thereof, so as to apply and .rub in the bronze immediately after the sizing operation,

from the press to a separate and distinct bronzing machine more or less remote from the press. And the invention also consists in certain constructions, arrangements and combination of parts, that we shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of our improved bronzing attachment, the same being shownin operative position relative to the cylinder of the press; Fig. 2 is a similar view of the other side of the attachment; Fig. 3 is a transverse sectional view of the apparatus; Fig. 3 is a section in the nature of a diagram. Fig. 4 is a horizontal section on the line 4.4 of Fig.1; Fig. 5 is a detail perspective view of acutofi forthebronze fountain; Fig. 6 is a detail sectional View on the line 6--6 of Fig. 2; Fig. 7 is a perspective view of one of the rubbing in devices; Fig. 8 is a transverse sectional view through such device; Fig. 9 is a detached perspective view of the rubbing rollers employed in connection with the devices illustrated in Figs. 7 and 8, and also a viewof some of the actuating and retracting devices for such rollers; Fig. 10 is a detail perspective view of the distributing and applying or feeding rollers, and Fig. 11

is a perspective view of the fountain and.

doctor rollers and their actuating devices, together with a portion .of the screw conveyer which is designed to feed the bronze to the fountain.

Corresponding and like parts are designated by similar characters of reference throughout the several views.

Referring to the drawings, the numeral 1 designates the cylinder of a multi-color printing press, driven in any desired way, as it is to be understood that our invention comprehends an attachment which may be easily applied to any bed and cylinder press. without altering the construction of the press and without interfering in any way with its ordinary functions. In the present instance, for the purposes of illustration, the'cylinder 1 is shown as provided with a gear wheel 1 meshing with an idler pinion 2 that in turn meshes with a pinion 3 on the drive or power shaft 4, the latter receiving its motion in any desired way, as from an electric motor (not shown) through the instrumentality of a driving belt 5.

6 designates the bed of the press.

The cylinder 1 carries the ordinary internally actuated sheet gripping fingers 8 designed to engage the sheets as they pass down the feed table 7, the sheets after being treated being finally deposited on the usual slatted frame 9 secured'to a shaft 10 which is oscillated at predetermined intervals by the pinion 11, rack segment 12, connecting rod 13,- lever 14, and pinion 15, which latter is geared to the pinion '3 through the interposed spur pinion 16.

The supporting frame or casing of our improved bronzing attachment may be of any desired construction and design, so'long as it is capable of supporting and housing the various elements of the mechanism, said casing being preferably shut in or inclosed on all sides except where it faces the cylinder 1, so as to prevent the bronze from flying about and being wasted. In the present embodiment of the invention, this casing includesside plates 17 that arecurved on their forward edges in the arc of a circle corresponding to the periphery of the cylinder 1 and a back 18 which may be secured to the side plates in any desired way, and which may be removable, if desired, so as o gain access to the interior of the casing whenever required without removing the entire attachment from the press. Curved bands 19 are disposed on the outer sides of the plates 17 at the forward curved edges thereof, said bands preferably carrying felt linings 20 designed to lie against the periphery of the cylinder 1 at the ends thereof so as to prevent the bronze from sifting out at these points, said bands being secured at the top and bottom to relatively short rods or bolts 21 working in apertured lugs 22 formed on the side plates 17. These bolts 21 are encircled by expansion springs 23 bearing against the lugs and the ends of the bands, and each band is formed at its middle with an apertured ear 24 designed to receive a pin 25 projecting outwardly from the adjoining side plate, this construction and arrangemerit of parts permitting the bands 19 to yieldingly rock and thereby compensate for the slight upward movement which is intertending longitudinally of the casing within.

the latter, and is fed into said trough from a hopper 29, the bronze being preferably continuously fed from the trough 28 by means of a spiral conveyer 30 secured to a 'shaft 31, said shaft being provided at one end with a sprocket wheel 32 over which a chain 33 passes. This chain also passes around asprocket wheel 34 on a longitudinally extending shaft 35 journaled in the side plates 17, said shaft carrying a sprocket wheel 36 connected by a sprocket chain 37 to a sprocket wheel 37 on the shaft of the cylinder 1, the sprocket wheels 36 and 37 being preferably so proportioned that the latter will make two revolutions to one revolution of the former. As the bronze leaves the trough 28, it passes into and through'a downwardly inclined laterally elongated spout 38, from whence it passes by gravity into a fountain 39, which extends from one side'plate 17 to the other, at the bottom of the casing. A fountain roller 40 is mounted in the fountain 39, and is engaged by a cutoff 41 which, as best illustrated in Fig. 5,

is constructed in two parts or sections, al-

vention is not limited in this regard, said cut-off being formed at its ends with trunnions 42 by which it is journaled, and the sections being provided with any desired number of tensioning bolts 43 Working through a bar 44 extending longitudinally of the casing and secured at its ends to the side plates 17 thereof. By adjusting the tension of the bolts 43, the amount of bronze passed out by the fountain roller may be regulated. The fountain roller 40 is intermittently actuated, the shaft of said roller having a ratchet wheel 40 secured to it' at one end, said ratchet being engaged by a pivoted pawl 41 carried by the arm 42 loose on the roller shaft, and a crank 42 is secured to said arm 42*, said crank being connected by a pitman 43 to an eccentric disk 44*" secured to one end of the shaft 35. (See Fig. 11.)

The fountain roller 40 is preferably co ered with plush or the like, and co-acting with it is adoctor roller 45, preferably of composition, the shaft 46 of the roller passing out through and working in slots 47 that are formed in the side plates 17. The ends of the shaft 46 are carried by the upper ends of substantially vertically disposed rocker arms 48 and 49 mounted on the outer sides of the plates 17, as best illustrated in Figs. 1 and 2, and secured to the ends of a longitudinally extending rod 50 journaled in said plates. The arm 49 is formed with a downward extension 51, to which a contractile spring 52 is connected at one end, the other end of said spring being fastened in any desired way to some stationary portion of the mechanism, whereby the spring will exert a tendency to rock the arms 48 and 49 in a direction to carry the doctor roller 45 from contact with the fountain roller 40. The roller 45 is intermittently and positively moved in the opposite direction, that is, into contact with the fountain roller 40, by means of a link- 53 connected at one end to the downward extension 51 of the arm 49, and at the other end to a lever 54, pivotally connected at its upper end 55 to the adjacent side plate 17, said lever carrying a roller 56 designed for engagement by a cam 57 on the shaft 35, this positive movement of the doctor roller serving to swing it from contact with the fountain roller 40 into contact with a distributing roller 58 which is, in the present embodiment of the invention, held continuously in contact with the bronze applying roller 59. Preferably, the rollers 58 and 59 are covered with plush or some equivalent fabric, and are geared together by the pinions 60, as best illustrated in Figs. 2 and 10, the roller 59 being normally in contact with the periphery of the cylinder 1 or the sheet held-thereon; such contact being only broken when, in the continuous rotation of said cylinder, the same has imparted to it a the bronze into the sized portions of the I sheet immediately after the bronze is applled thereto by the roller 59 is performed bya laterally reciprocating bar 61 having its working face covered with beaver fur 62 or some equivalent soft substance. This bar 61 is secured at its rear side to any desired number of rods 63, there being three of these rods in the present instance, as illustrated in Fig. 4. The rear ends of the rods 63 are inserted in blocks 64 that are secured by set screws or similar fastening devices to a laterally reciprocating rod 65, the rod 65 being provided at one end with a bearing block 66 working through one of the side plates 17 and being provided at its other end with an eccentric strap 67. The strap 67 accommodates an eccentric roller 68 which is carried by a disk 69 secured to the forward end of a horizontally disposed shaft 70 journaled in bearings 71 formed on the outer face of one of the side plates 17. The shaft 70 carries a spiral gear 72 meshing with a corresponding gear 73 secured to the outer end of a longitudinally extending shaft 74. The other end of the shaft 74 carries a sprocket wheel 75 connected by a chain 76 to a larger sprocket 77 carried by the shaft 35.

In order to automatically move the continuously reciprocating bar 61 back from the cylinder 1 at predetermined intervals,

we have provided the following mechanism:

Each of the blocks 64 has secured in it a bushing 78 and is recessed on its rear side to accommodate a recessed section 79 which operates in the nature of a crank and which is fastened to the bushing by a set screw and pivotally connected to the rear end of the rod 63, as best illustrated in Fig. 8. The bushings 78 of the blocks 64 are grooved to receive splines or feathers 80 formed on a rod 81 extending longitudinally in the framework back of the rod 65, one end of the rod 81 extending to the outside of one of the plates 17, and carrying a curved arm 82. The arm 82 is fixed on the rod 81 and is secured intermediate of its ends to one end of a contractile spring 83, the other end of said spring being secured to the adjoining side plate. A roller 84 is carried by the upper free end of the arm 83, said roller, as best illustrated in Figs. 1 and 9, being designed for engagement by a cam 85 secured to a shaft 86 journaled in the side plates, said shaft carrying a gear wheel 87 which meshes with a gear wheel 88. The gear wheel 88 in turn meshes with a gear wheel 89 on the shaft 35. By this means the continuous rotation of the shaft 86 will,

'- turn the rod 81 so as to positively carry the bar 61 forwardly and hold it with its work- 7 ing face against the cylinder 1 or sheet car ried thereby. As soon as the cam 85 leaves the roller 81, the spring 83 will be permitted to act and it will pull the arm 82 rearwardly, this resulting in turning the rod 81 to rock the cranks 79 rearwardly so as to draw the rods'63 rearwardly in the blocks 61 and move the'bar 61 away from the cylinder. This action takes place without any cessation in the reciprocating movement of the bar 61, as the blocks 64 are splined on the rod 81, as before described.

The secondstep in the process of rubbing the bronze into the sized portions of the sheet while it is passing through the attachment on the printing cylinder 1, is performed by a roller 90, and the final step in this'operation is performed by a corresponding roller 90*, the. roller 90 being mounted above the bar- 61 and the roller 90 above the roller 90. Both of these rollers are preferably covered with beaver fur, like the operative face of the bar 61.

91 designates the shaft of the roller 90 and 91 designates the shaft of the roller 90. Each of these shafts is journaled at its ends in eccentric bearings 92 carried by the side plates 17 whereby when a partial rotation is imparted to said bearings, the rollers will be backed away from or carried forwardly against the cylinder 1 or sheet thereon, at predetermined intervals and in succession, the movement being diagrammatically illustrated in Fig. 3. The rollers are, however, continuously rotated, in the present embodiment of the invention, about the shaft 91 of the roller' 90 carrying atone end a sprocket wheel 93,. and the corresponding end of the shaft .91 carrying a sprocket wheel 94. the sprocket chain 95 passing around the said wheels 93 and 94 and around a. sprocket wheel 96 secured to the adjoining end of the shaft 74. To secure these automatic movements of the rollers 90 and 90" toward and away from the cylinder 1 (referring now particularly to Fig. 9, and first to the roller 90), the bearings 92 of the shaft 91 have crank arms 97 connected to them. The arms 97 are pivotally connected by links 98 to rocker arms 99 secured to a longitudinally extending shaft 100 mounted in the side plates 17 and contractile springs 101 are secured to the rocker arms 99 and to the side plates 17, tending to move said rocker arms in such a direction that the crank arms 97 will be swung around to carry the eccentrically mounted shaft 91 away from the cylinder 1. One of the rocker arms 99 is joined to a lever 102 extending rearwardly from the rod 100 and carrying a roller 103, said roller being designed for engagement by a cam 104 on the shaft 86, whereby as said shaft rotates, the engagement of the cam 104 with the roller 103 will result in moving the rocker arms 99 against the tension of the springs 101 so as to turn the eccentric bearings 92 in a direction to carry the roller 90 forwardly against the cylinder 1. Correspondingly, the bearings 92 for the shaft 91 have crankarms 105 secured to them, said crank arms being joined by links 106, to rocker arms 107, to which contractile springs 108 are connected. The arms 107 are secured toa rod 109'to which a lever 110 is also connected, said lever carrying a roller 111 designed for intermittent engagement by a cam 112 on the shaft 86, the cams 10 1 and 112 being so timed that the former will work in advance ing 118, and operated to suck the loose bronze out from the casing, whence it may be passed to the ordinary bafile box or, if desired, passed by the tube 119 to the hopper 29. The, side plate 17' distant from the fan may be formed with a screened opening 120. The rollers 90 and 90 are cleaned by means of cleaning rollers 121 that are journaled in side plates 17 contiguous to the rollers 90 and 90*, each of the cleaning rollers 121 being formed with any desired number of kerfs or grooves disposed longitudinally therein and designed to receive and hold, by

any desired means, cleaning strips which I may be of any desired character but; which are preferably formed of wire fabric in double lengths with the doubled edges outermost, as indicated, at 121*. The shaft of each of the rollers 121 is provided at one end with a sprocket wheel 123 and sprocket chains 123 pass over these sprocket wheels and over corresponding sprocket wheels 122 secured to the adjoining ends of the shafts of the rollers 90 and 90 It will, of course,

be understood that the rollers 90 and 90 .ing rollers 121 will be out 'of engagement with the peripheries of the rollers 90 and 90; when said last-named rollers move back-' wardly or away from the cylinder 1, their peripheries will come into contact with the rapidly revolving wire fabric cleaning strips, and the same will effectively clean the peripheries ofthe rollers 90 and 90 of the bronze which would otherwise adhere thereto. This bronze may be readily removed as it comes off the rollers 90 and 90 by means of suction boxes 123 which are mounted in juxtaposition to the cleaning rollers 121 within the casing and which have pipe connections 123 with the main fan 117, whereby 'said fan may not only suck the loose or excess bronze from the other partsof the casing, but will also act to directly carry the bronze from the rollers 90 and 90 and the cleaning rollers 121 before described. The casing of the suction fan 117 is connected by means of'a duct 119, shown in in Fig. 2, to the hopper 29 and thus returned to the font. Thus noneof the fine dust of the bronze is ejected into the room or lost but a continuous circulation is kept of the bronze, the bronze being applied from the font to the paper, rubbed in, dusted therefrom by the rollers 90 and 90*, then taken therefrom by the cleaners 121 and 121 and thence drawn into the suction tubes 123 and 30 from thence passed back'to the hopper again.

Furthermore it will be seen that these suction tubes not only take the bronze powder from the rolls 9 and 90*, but that they will act to draw in any loose bronze powder fl0ating inthe air inclosed within the casing'of the apparatus. This not only eliminates waste, but is far more sanitary than the or. dinary operation. Furthermore inasmuch as the font is located at the lower portion of the casing, the bronze as it is taken from the font'does not fall down through the casing as it would be liable to do were the font located at the upper portion of the casing. It is to be understood that our invention is rot limited to this construction of means for directly removing the waste, and that separate fans may be provided, if desired, for conveying .the powder from the suction boxes 123, but we prefer the use of the single fan 60 117 to serve all of these functions. Preferably, the rollers 90 and 90 are vibrated in opposite directions from each other and 1on gitudinally of their length at the same time they are rotated; As one means for effecting this result, although it is to be understood that various other means may be employed for this purpose, one end of each shaft 91, 91 is provided with a grooved collar 124, said collars being engaged by an interposed cam 125 which is mounted on a stub shaft 126 secured to and projecting outwardly from the adjoining side plate 17. Movable with the cam 125 is a sprocket wheel 127. A sprocket chain 128 passes over 66 the sprocket wheel 127 and also over a dotted lines in Figs. 1 and 3 and in full lines sprocket wheel 129 secured to the adjacent end of the shaft 74, whereby as said shaft rotates, the cam 125 will be rotated to impart the desired vibratory movement to the shafts 91 and 91 and the rollers 90 and 90 70 From the foregoing description in connection with the accompanying drawings, the operation of our improved bronzing attachment for multi-color or other label printing machines will be apparent, as the operations and correlated actions of the various elements of the mechanism have been I described along with the details of construction and relative arrangements of the parts. But it may be stated, generally,-that in the so practical use of the apparatus, an intermittent movement will be imparted to the fountain roller 40 so that the latter will pass the bronze to the doctorv roller 15, and said roller will, at predetermined intervals, vibrate between the roller 40 and the distributingroller 58, conveying the bronze to f the latter, and-said roller 58 passing it to the roller 59 which will applyit to the sheet. The bronze will then be rubbed in by the laterally reciprocating bar 61 and the rollers 90 and 90 At predetermined intervals,the sheet gripping fingers and the adjoining open portion of the periphery of the cylinder 1 will arrive at and commence to sweep past the bar 61 and rollers 90 and 90, and at this time the bar and said rollers will automatically move back from the periphery of the cylinder and will then in turn be positively moved forwardly again into their operative positions by the mechanism hereinbefore specifically set forth. and illustrated in the accompanying drawings.

While the accompanying drawings illustrate what we believe tobe the preferred embodiment of our invention, it is to be understood that the invention is not limited thereto, but that various changes may bemade in the construction, arrangement and proportions of the parts without departing from the scope of the invention as defined in the appended claims.
