Srarns @KTE WALTER SCOTT, OF PLAINFIELD, NEW JERSEY.
MULTICOLOR-PRINTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 490,456, dated January 24, 1893.
Application filed April 8. 1891. Serial No. 388.164. (N0 model.)
To all whom it may concern.-
Be it known that I, WALTER Soon, a citizen of the United States, and a resident of Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Multicolor-Printing Machines, of which the following is a specification.
My invention relates to that class of printing machines which print two colors, and consists in combinations of devices hereinafter described and particularly pointed out in the appended claims.
In the accompanying drawings forming a part of this specification Figure 1 is a side elevation of one form of mypresent invention. Fig. 2 is a side elevation of a modification. Figs. 3, 4 and 5 are side elevations of other modifications thereof; the said Fig. 5 being in two parts, the sections joining on to each other end to end to complete the machine.
The type bed T is reoiprocated by any suitable means, such for instance as a crank, connecting rod, rolling gear wheel, a rack on the stationary frame, and a rack on .the bottom of the bed with which racks the gear wheel The oscillatingimpression cylinder 0 is geared to and driven by the type bed T by racks and gears (not shown) in a well known manner.
The type bed T carries two forms, which may be letter press. forms or lithographic stones, or other forms for multi-color printing.
The machine shown in Fig. 1 hasafirstcolor stone l1, and a second color stone 12, ink tables 13, 14.. In all the-figures the table 13 is inked from a fountain 15 and by means of distributing rollers 17, and a dnctor 19; the table 14: is supplied with ink from the fountain 16 by ductor 20, and has distributing rollers 18. The first color form is inked by rollers I and the second color form is inked by rollers 1 The inner two of the rollers I are lifted as the second color form approaches them so as not to apply ink thereto, and the inner two of the rollers I are lifted as the first color form approaches them so as not to apply ink thereto by any suitable means, such for instance as shown in my patent No. 430,889, dated June 24., 1890. When the machine is being used for lithographic purposes I employ water rollers 21, which are supplied from a fountain 22 by a ductor roller 23. These Water rolls wet both forms on the forward stroke of the bed and are lifted to clear each ink table and also during the return stroke of the bed. If desired similar rolls may be placed between the ink rollers I and the im-v pression cylinder, as in a prior application filed by me. These water rolls may be lifted by means similar to those commonly used.
The oscillating impression cylinder O-makes rather more than one complete revolution to each stroke of the bed. The cylinder 0 has two impression surfaces 24. and 25, and grippers 26 and 27 to co-operate with these surfaces. Guides 28, 29 may be employed to hold the paper from falling away from the cylinder.
The feed may be by hand from a feed board, or by tapes from cutting cylinders, or it may be to an intermediate feed cylinder from a feed board. The feed may be located as shown in Figs. 1, 2 and 5, or as in Figs. 3, and 4. In Figs. 1 and 2,1 have shown a feed cyli-nder F having grippers 30, which take the sheet from a feed board 31 and gages 32 at the proper times, and deliver the same to the grippers 26 of the first impression surface 24. of the cylinder 0, as hereinafter described.
The transfer of a sheet, after being printed an arrangement as an equivalent of the cyl inder shown. The retaining cylinder R is furnished with grippers 33, and takes the sheet already printed in one color from the first impression surface and delivers it to the second impression surface of the cylinder 0.
Guides 34. prevent the sheet from falling away from the retaining cylinder. After the sheets have been printed a second time they are delivered from the second impression surface. I preferably use a delivery cylinder D having grippers 35'for taking the sheet from the impression cylinder, and in connection therewith to use tapes, as 36, and fliers 37, to lay the sheet upon a delivery board 40. The tapes 36 pass about the cylinder D and rollers (Z. Pressure rollers 38 acting in conj unction with the cylinder D, feed the sheets forward onto the fliers after the grippers 35 of the cylinder D have opened. The rollers 38 may be upon pivoted arms 39. \Veights or springs may be used to produce the desired amount of pressure between the rollers 38 and the cylinder D.
It is to be observed that while the cylinder 0 oscillates, the feed, retaining and delivery cylinders each have a rotary motion the direction of which is indicated by arrows. For giving these cylinders their rotary motion any suitable devices may be used, such for instance as are set forth in my Letters Patent dated July 28, 1891, and numbered 456,741.
In Figs. 1 and 2 the cylinders F and D would be driven from the cylinder C by the means referred to, and the retaining cylinder R is driven from the cylinder D bya gear as G. In Figs. 3, 4 and 5, either of the cylinders R and D may be driven by the described means and the other be driven by the gear G. It must be noted that the surface speeds of the cylinders F, D and R are the same as that of the cylinder 0.
The machines shown in Figs. 2, 3, 4t, and 5 have first color forms 11 and second color forms 12. These forms may be ordinary letter press or other desired forms. In Figs. 3, 4 and 5 the feed shown is direct from a feed board 31 and gages 32 to the grippers 26 of the first impression surface of the cylinder 0. In Figs. 3 and 4 the board 31 is located above the impression cylinder, While in Fig. 5 it is to one side of and below the cylinder 0.
The delivery cylinder may be above or be low the retaining cylinder, as may be desired. In Figs. 1, 2 and 3, I have shown it above, and in Figs. 4 and 5 I have shown it below the retaining cylinder.
In Fig. l, the delivery cylinder D and tapes 36 run the printed sheet between pressure rollers 38 and rollers (Z onto tapes 41 and the fliers 37, which deliver the same to the board 40. The tapes 41 pass about the rollers d and n.
In Fig. 3 are shown but three rollers I to ink the first color form and the inner one only of these rollers is lifted to clear the second color form.
The grippers of the various cylinders, the feed gages, the fliers, the tapes, and the duct or rollers are all operated at the proper times by the mechanisms commonly employed for that purpose. I have not shown such mechanisms, as their construction is well known.
Promising that in practice there would be a sheet on the retaining cylinder R (as shown by the broken line in Fig. 1) when the parts are in the position shown, the operation of the parts shown in Figs. 1 and 2 is as follows:The bed T moves to the right rotating cylinder C in the direction of the arrow in full lines. The grippers 27 of cylinder G close and take the sheet, printed in one color, from cylinder R, whose grippers 33 open at the same time. The grippers 30 of the cylinder F close and receive a sheet from the board 31, and gages 32 at or about the time the cylinder 0 begins to move in the direction indicated by the said arrow. Next, the grippers 26 of the cylinder 0 close at the time the leading edge of the sheet from board 31 is on or near the plane of the axes of cylinders O and F and grasp the sheet, the grippers 30 opening simultaneously. The inner two of inking rolls 1 are dropped to the positions shown in dotted lines as soon as the first color form has moved from under them. The cylinder 0 is lowered as soon as the ink table 13 has moved from under it. The first color form now begins the first impression on the sheet on the surface 24:. When grippers 26 of cylinder 0 approach the plane of the axes of cylinders C and R, they open and the grippers 33 of cylinder R close and grasp the sheet and the sheet is transferred to the cylinder R, the grippers of which remain closed until the beginning of the next forward stroke of the bed. The sheet on impression surface 25,whichisalreadyprintedinonecolor,inpractice, next takes an impression from the second color form. \Vhen grippers 27 approach the plane of the axes of the cylinders C and D, they open and grippers 35 close and grasp the sheet, and the sheet is transferred to the cylinder D. It will be understood that grippers 27 remain closed the first time they pass cylinder D. As soon as the second eolor form has given the impression, the cylinder 0 is raised to clear the inking table 14, and re-- mains up during the return stroke of the bed, and after, as hereinafter described. The grippers 35 of delivery cylinderD open as soon as they pass the pressure roller 38, and the sheet is run upon the fliers 37 by the tapes 36. The fliers 37 lay the sheet upon the delivery board 40. As the second color form approaches the inking rolls I, the inner two rolls are lifted to the positions shown in dotted circles. On the return stroke of the bed the cylinder 0 is moved in the direction of the broken arrows (in all the figures) by the bed, but is clear of the bed, the cylinder being in its raised position indicated by broken circles over and on the journals of cylinder C. The inner two of rolls I are lowered as soon as the second color form is from under them. The inner two of inking rolls 1 are raised as the first color form approaches them. At the end of the return stroke, the parts are in the positions shown.
The lifting of the inking rolls described above, may be accomplished by the means shown in my patent No. 430,889, dated June movement.
24, 1890. Like means maybe used to lift the water rolls, if desired.
It will be understood that the grippers of the various cylinders, when idle, open back into the cylinders, or close down to their working positions, whichever may be desired, so as to clear the passing portions of other parts.
The operations of the modifications shown in Figs. 3, 4 and 5, will be understood readily without further explanation, being analogous to that just described.
The sizes of the feed, retaining and deliv ery cylinders relative to that of the impression cylinder can be varied as may be desired without departing from my invention. In all the cases shown, while the cylinder 0 makes rather more than one revolution to each stroke of the bedT (thatis, it is revolved far enough to take the already printed in one color sheet from the retaining cylinder,print another color on it and pass it to the delivery cylinder), the number of turns of the feed, delivery and retaining cylinders varies. In Fig. 1, the feed and delivery cylinders each make seven turns and the retaining cylinder five turns to oneturn of the driving crank. In Fig. 2 all three cylinders make five turns to one turn of the crank. In Figs. 3 and 4, the delivery and retaining cylinders make seven and five turns respectively to one turn of the crank; and in Fig. 5, each makes four turns to one turn of the crank. Other proportions may be adopted if desired.
It will be noted that the retaining cylinder takes the once printed sheet from the first impression surface during the printing movement of the impression cylinder; (11. e., during the forward stroke of the type bed) and retains it until the next printing movement of the impression cylinder, When it gives the sheet to the second impression surface.
The feed, retaining and delivery cylinders are practically at rest at the moments when the impression cylinder is reversing its motion; it is at one of these times that the feed cylinder takes a sheet from the feed board, but only When the impression cylinder is beginning its printing movement, and not when it is beginning its. reverse or non-printing Other dampening devices than those shown may be employed without departing from this invention.
The impression cylinder shown in all the figures has its second impression surface in juxtaposition to the bed and ink table. To take an impression on the sheet on this surface, the cylinderO must revolve once and as much more as will cause the end a of the surface 25 to pass the vertical through axis of cylinder 9. Thus in Figs. 1 and 2, it must revolve about once and a quarter, in Figs. 3 and 4 about once and a third and in Fig. 5 about once.
I do not herein claim the combination of an impression cylinder and a feed cylinder both coming to rest at intervals,with a feeder from which the feed cylifider takes sheets while it is at rest, as the same is the subject matter of a claim in my prior application for Letters Patent Serial No. 385,241, filed March 16, 1891.

In a multicolor printing machine, the combination of an oscillating impression cylinder having first and second impression surfaces, with a retaining cylinder taking the once-printed sheet from the first impression surface during a forward movement of the impression cylinder and delivering the same to the second impression surface after the impression cylinder has made its backward movement, substantially as and for the purposes described.
