UNITED STATES PATENT OFFICE.
HARRY F. \VYATT, OF NEW YORK, N. Y., ASSIGNOR, BY MESNE ASSIGNMENTS,
TO THE WVYATT CHROMATIC PRINTING COMPANY.
CHROMATIC-PRINTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 420,399, dated anuary 28, 1890.
Application filed August 3, 1888. Serial No. 281,908. (No model.) Patented in England August 31, 1889, No. 12,182, and in 7 France October 28, 1889, No. 200,015.
To all whom it may concern.-
Be it known that I, HARRY F. WYATT, a
subject of the Queen of Great Britain and Ireland, residing in the city, county, and State of New York, have invented certain new and usefulOhromatie Improvements in Chromatic- Printing Machines, (for which I have obtained patents in Great Britain, No. 12,182, dated August 31, 1889, and in France, No. 200,015,
dated October 28, 1889,) of which the following is a full, clear, and exact description, such as will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, and to the letters and I 5 figures of reference marked thereon, which form a part of this specification.
The object of my invention is to provide a chromatic-printing device which can be used on any ordinary cylinder or rotary printingpress in connection with the ordinary stereotype-plates, and will make chromatic impressions while such plates are making common black impressions. I attain this object by the mechanism illustrated in the accompany- 2 5 ing drawings, in which Figure 1 is a top view of the device complete; Fig. 2, a longitudinal sectional view on the line 00 0c in Fig. 1. Fig. 3 is a transverse sectional view on the line 3 y in Fig. 1; and
0 Fig. 4 shows the details of construction of parts O, 0, O and O ,E E E E and F F in Figs. 1, 2, and 3.
In Fig. l A represents the cylinder of a printing-press, upon which the ordinary stere- 5 otype-plates B B are clamped in the usual manner Separate stereotype-plates are made ar the articles to be printed in color, (repre sented by O O O' 0 which fit in openings cut to receive them in the fixed stereotypeo platesB B On the underside of these movable stereotype-plates C O O O are openings, with a groove on each side the opening running obliquely from the top of one side to the bottom of the other, as best shown in Figs, 2,
5 3, and 4. The purpose of these grooves is to receive the lips of the heads of the T-shaped wedges orlifts F F, thereby holding the stereotype when inverted by the revolution of the cylinder and insuring an accurate and positive rise and fall of the stereotypes C O O C as the wedges are workedunder them. These wedges are part of a fiat plate E E E E made of steel or any other suitable material, shaped to conform to theeylinder, which plate is fastened by screws or clamps to the sliding 5 5 bar D, which works within a dovetailed-shaped groove out in the cylinder A. This bar has screw holes or clamps arranged along it at convenient intervals, so that the plates E E E E can be affixed wherever desired or taken off altogether when movable plates are not to be used. The bars ,D D are connected with cams H H by a revolving steel button or'roller P, which works in a space K between the faces of the cams H H ,as shown on Fig. 1. These cams H H are so shaped and arranged with reference to each other that when the cylinder A revolves the bar D, being operated by them through pressure on the roller P will be moved laterally in and out of the groove in 7c the cylinder A, and the plates E E E E having the wedges F F on them, being attached to the bar D, the wedges will also move laterally, and, their heads working within the grooves in the stereotypes O O 0 O these stereotypes will be raised and depressed according to the relative positions of roller P between the cams H II. Therefore when the bar D is at the position h on the cams II II, as shown in Figs. 1, 2, and 3, this position being the nearest to the cylinder A, the wedges will be driven into their furthest extent under the plates O O O 0 thereby raising them, as best shown on the left-hand side of Fig. 2, and when the bar D is at the position 7L2 on the' cams H H it is drawn out of the cylinder to a position that brings the wedges F F to the center of the movable stereotype plates O C O C and holds them exactly flush, with the surface of the plates B B, as best shown on the right-hand side of Figs. 2 and 3, and when the bar D is at the position it on the cams II II it is withdrawn farther still from the cylinder, thereby causing the plates 0 O O O to be depressed bythe wedges below the surface of the plates 13 B. These positions h h k so occur on the cams H H as to cause the plates O O O O to be raised above the plates B B at the time they are traveling between the paper Q (or blanket roller O) and the black-ink roller M, as shown in Fig. 3, when they receive ink of such color as desired from an inking-roller N, which can, if thought best, be made to feed different-colored inks to each of the plates 0 0 C 0 and then to cause the plates 0 O C O to be depressed below the surface of the plates B 13 just prior to reaching the black-ink roller M, as shown by dotted lines on the left-hand side of Fig. 3, so that while the stereotype-plates B 13' are receiving black ink from the black-ink roller M they receive no black ink, but remain charged with the colored ink they received from the coloredink roller N at position it, and, finally, to cause the plates C C C O to be raised to such a position as will bring their surfaces exactly flush or level with the surfaces of the plates B B just prior to their reaching their point of contact with the paper Q, so that they will imprint the paper in color at the same time that the plates B B are printing it in black. tached to the side frame of the press; but in these drawings only such parts of the press and cams are shown as are affected by my invention, the other parts being omitted to avoid confusion.
The devices and combinations of devices herein shown are capable of use in a more or less modified form on other kinds of pressesas, for instance, a press in which motion is imparted to a bed-plate; and I therefore do not limit myself to their use in the particular apparatus described, nor do I confine myself to the exact mechanism herein shown for securing a lateral motion to the barD, as, if desired, a guide or gage or a system of gearing or other well-known mechanical movements can be substituted for the cams shown. In like manner other devices than lips to the wedges may be used for securing the movable printingsurfaces.
Having thus described my invention and the operation thereof, Iclaim as follows, using for convenience in all cases the expression printing-surface to signify not only stereotype-plates, but also eleetrotypes, molds, typeforms, cuts, engravings, &c.,which are equally capable of being used in connection with the other elements of my invention:
