ing and Coating Photographic Postal Cards,

of which the following is a clear, full, and exact description.

My invention relates to machines for priiating and coating photographic postal car 3.

Heretofore it has been customary to first coat the heavy paper used for postal cards with a suitable emulsion; then set the emulsion by subjecting the same to a low temperature; then dry the same with a high temperature, and then cut the coated paper into postal card sizes, after which they are printed on job presses. This method not only consumes considerable time, but, by reason of the subsequent necessary handling, increases the liability of the cards becoming soiled, and the liability of the coating being injured by the moisture of the hands;

and the lines of the printing showing through the card and cracking or fracturing the coating, and contribute to the general deterioration of the cards.

The object of my invention is to avofd all of these objections, and to enable the coating to be evenly spread over the card, and I the pr nting ink to dry at the same time as i and by reason of these advanthe coating, tages to almost double the output. This I accomplish by the means hereinafter fully described, and as particularly pointed out in the claims.

In the drawings :Figure l is a side elevation of a portion of a photographic emulsion coating machine having my invention embodiedtherein and applied thereto. Fig. 2 is a front elevation of the printing mechanism of my invention. Fig. 3 is a side elevation of the same. Fig. 4 is a side view, on a slightly larger scale, of one of the type disks of said machine. F ig, 5 is a transverse section through a fragmentary portion of the same, drawn to a larger scale. Fig. 6 is a side view of the type disks and impression roller and shafts therefore removed from the machine. lar view of the end of the ink-roller and dis- Fig. 7 is a simi tribution rollers therefor. Fig. 8 is a vertical front elevation of an end of one of the recessed rollers used for tightening the strip of paper. Fig. 9 is a vertical side elevation of the drying chamber. the structure being broken away at the end nearest the portion of the mechanism shown in Fig. 1. Fig. 10

is a transverse vertical section thereof taken on line 1010 Fig. 9 and drawn to a. greatly enlarged scale.

My invention comprises, principally, the

combination of a photographic emulsion coating machine, and a printing press, both of which are modified in several particulars to better enable them to accomplish the objects in view.

Herctofore the paper was fed to the coating devices of the coating machine direct from a continuous roll of paper, and from V the coating devices the paper pursued a vertical course for ashort distance and then horizontally into an inclosed chamber A, in

charged into the top of said chamber;\

through a pipe B, substantially as shown in Fig. l of the drawings, and by means of which the coating was set The coating devices referred to consisted of a series of idle rollers a, a, which tighten up the paper,

and an immersing roller 1) down around which the paper passes, after it leaves the last roller (1, and is coated by dipping into a liquid emulsion contained in asuitable pan 0. After this coating is applied. the paper pases vertically to and around a suitable guide roller into the cold air chamber A and it is set on the paper while passing through said chamber, after which the paper passes through a warm air chamber (Figs. 9

and 10) by means of which it is thoroughly dried.

It makes very little. if any. difference so far as the operation of the old coating machine was concerned. whether the paper. 10..)

after it left the roll, was kept in a well defined path or not, but inmy invention. I consider this very essential, particularly as it is desired that the moist printed surfaces of the paper should always run in the circumferential groovesor transverse corrugaparted to the paper while in transit through from the roller 3 and transmit it to the sei tion to give a long sweep to the paper beof a vertical standard or upright portion which are provided, near their u to the extension, and the other end to a pin tions or depressions w of the rollers a, a, and j b, and thus avoid smearing the ink over the paper, and, it is also an object of myinventween the supply roller and roller (1 so that the vibrations imparted to said paper, while in transit through the printing machine will not affect nor prevent the steady continuous movement of the paper around the roller 0, while being coated. I accomplish this guidance ofthe paper by means of a comparatively low frame consisting of parallel rails G, arranged so that one will be on one side of the path of the slack paper between the printing machine and roller a, and the other on the other side, and supported by suitable legs. These rails are provided with a series of equidistant upwardly projecting arms against which the edges of the paper come in contact as it moves along. These arms have their lower ends bent horizontally outward, and extended sidewise through openings in rails C, in which they can be made adjustable'by means of set-screws or otherwise, to enable said arms to give the desired direction to the paper. At the end of frame C farthest from the coating device, a printing press takes the paper direct from the roll, and the length of the stretch of paper between this printing mechanism and said coating device is such that the paper hangs slack and sags so that any vibration imthe press will be absorbed before it reaches the roll a.

The printing mechanism referred to comprises two side-frames 2, 2, each consisting per ends, with bearings for thejournals o the shaft 8 of an inking-roller 3. At their upper ends these standards are provided with brackets 4, the screw-plate of which is bolted or otherwise attached to said side-frames, and have two or three arms projecting therefrom Whose extremities are provided with open bearings for the journals of the ink-distributing rollers, 6 and 7, that bear against the cylindrical surface of the roller 3. Next its bearings, shaft 8 has the bosses of a couple of arms 9 loosely mounted thereon, the outer ends of which are made tubular and have pistons or extensions 10 telescoping into their outer ends, and held in engagement therewith by contraction springs 11, one end of which latter is secured to a pin attached projecting from the arm. The extremities of the extensions 10 are provided with bearings for the journals of the idle inkingrollers 12, 12, that are adapted to takeink ries of metallic printing disks 13.

Disks 13 are mounted upon a,shaft 14,

opposite which is journaled in suitable bearings in the side from which their bosses are shown to project, is provided with a circumferential flange 15, whose inner side is undercut, and the stereotype or elect-retype plate 16 is secured upon the cylindrical circumference of thedisk between flange 15 and the outer edge of segmental plate 17, the inner surfaces of which latter are provided with undercut grooves into which the beveled edge of plates 16 enters and clamped by'tightening plates 17 in place by set-screws 18, tapped through the same into the side of the disk. These printing disks engage an im-' pression roller 19, the circumference of which is smooth from end to end. This im-- pression-roller is substantially the same as the impression-roller of any webperfecting press, and at one end its journal extends through its bearing in the. side-frame and is provided with asuitable pulley 20, by means of which said shaft is driven through the medium of a belt 21, that takes its motion from a pulley 22 on the end of a transverse shaft having hearings in the ends of the longitudinally elongated cold air chamber A, which latter derives motion by a sprocket and chain connection with the shaft of the adjacent drum 23 around which apron a travels. I p

The journal of the impression-roller 19 pulley 20 extends through its bearings and is provided with a gear 24, which engages and drives a suitable gear 25 upon the adjacent end of shaft 14 of the printing disks, and the latter, at its opposite end has a gear 26 secured to its extended end which engages an idle barrel-gear 27 that impart-s motion to shaft 8 through the medium of a gear 28. The end of shaft 8, opposite gear 28, extends through its bearings a suitable distance and has secured thereto a cam 29, that has a transversely disposed zigzag groove or runway therein, which is engaged by a stationary pin 30 projecting transversely from the end of the curved arm of a bracket 31, whose supporting-plate is suitlongitudinally reciprocal motion, andidlegear 27 is made barrel-shaped to accommodate this side motion of gear 28.

The bearings of the journals of shaft 14 sea,

are made in bearing-blocks 32 that have a slight vertical movement in suitable openings made in the side-frames. Normally disks 13 will bear down upon the circumference of the impression-roller 19, but when it is desired either to pad the circumference of said roller, 19, or to remove the stereotype or electrotype plates from the circumference of the disks, it is desirable to lift said disks and shaft 14 bodily. This I accomplish by the means of toggle-joints 33, the ends of the lower links of which are pivotally connected to the inner surfaces of the side-frames 2 above the bearings of the journals of the ings, shaft 14 and disks 13 are lifted out of engagement with the impression-roller, and when said handles are raised, as shown in Fig. 3, the disks are lifted into, engagementwith the impression roller. v The cogs of gears 24 and 25'are, preferably, made longer than shaft 8 so as to permit of the separation of the disks from the impression-roller without getting out of mesh.

The journals of the roll of paper 35 are mounted in open bearings located near the ends of the horizontal member and near the angles of inverted L-sha-ped frames 36, whose extremities are secured in suitable manner to the basal flange and the adjacent edge of the side-frame 2. As it unrolls the web of paper passes to and around an idle-roller 37 journaled in vertically disposed bearingblocks 38, which latter are suitably mounted in openings in the ends of a bracket 39, projecting from the adjacent edge of the sideframes, 2. From this when the web of paper pursues an upward course ,to and over the impression-roller, and between the same and the printing-disks, and then extends in slightly downward direction to and between idle-rollers 40 and 41 that are journaled in bearing-blocks located one above the other in a suitable vertical opening in the end of brackets 42, projecting from the edge \of the side-frames 2 opposite that from which brackets 39 project. The lower of these two idle-rollers 40, has a pinion 43 secured to the extended end of its journal adjacent to gear 24, and is connected to and driven by the latter through the medium of an idle pinion 44.

-When passing between the printing-disks and the impression-roller the upper surface of the paper will be printed upon, so, in order to avoid the possibility of the fresh ink being smeared or blurred by its passage between'rollers 40 and 41, I provide the upper roller 41 with a series of circumferential grooves or transverse corrugations 45 in the same transverse plane as disks 13, the width I of which corresponds to the width of the stereotype or electrotype plates by which the printing is accomplished. After passing through the cold air chamber for setting the emulsion, etc., the paper continues its course to and through the drier or warm air chamber hereinbefore mentioned. This drying apparatus comprises an elongated compartment 50 through which the paper is conveyed on an endless apron 51 that moves at the same speed as apron a in the cold air chamber A. The warm air is fanned from a heat generator 52 near one end of the chamber by means of a blower 53 and is sent through a main fine 54 and distributed at various points throughout the length thereof by branch-pipes 55. These branch-pipes arise to the height of the chamber. where they are turned laterally and enter the longitudinally disposed feed trough 56 which latter has a narrow opening 56 in its bottom toward which the side walls of said trough converge. This opening is close to the upper surface of the paper and directs a current of warm air against the central portion of the same, which current is distributed to either side by the adjustable plates or wings 57 hinged to the lower edges of the trough. After passing through this warm air chamber the paper becomes thoroughly dried and is then conveniently wound in a roll at the outer end of the chamber.

The operation of the mechanism involved in myinvention has been set forth in the foregoing description, and it is suflicientto say in conclusion that by means of this mechanism the'operation of the machine is greatly facilitated; the printing of the card in no way affects the coating of the same for when. the freshly coated paper leaves the dipping pan and travels vertically the emulsion spreads evenly over the surface opposite the printed side, and when the emulsion is set, in transit through the cold air chamber, the coated surface will be even andunafl'ected by the printing striking through. Both the printing and the coating are dried at the same time, and the output, both as to quality and quantity, is greatly improved.
