CHROMATIC-PRINTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 538,986, dated May '7, 189 5. Application filed July 2, 1894:. Serial Ila. 518,270. (No model.)

To all whom it may concern:

Be it known that I, THEODORE J. TURLEY,

a citizen of the United States, residing at Nashville, county of Davidson, Tennessee, have invented certain new and useful Improvements in Chromatic-Printing Devices, of which the following is a specification.

My invention relates to improvements in chromatic printing devices, particularly of the type shown in my pending application, Serial No. 489,831, filed November 2, 1893, and it is specially applicable to newspaper and magazine, or similar Work where it is desirable to print advertisements, announcements, headings and the like, in colors contrasting with the body of the paper, magazine, &c.

My objects are to simplify to a great extent the mechanism for operating such devices; to provide means for readily'placing the device within the main form at any point desired in the outside column or columns, without confining it to a particular space in the column; to provide means whereby the width of the-colored matter to be printed may vbe easily varied without being compelled to provide separate complete forms for various widths, such as one, two or three columns; and to reduce the space lost in inking the supplemental form and insure the thorough inking of the whole of said form. I attain these objects by the mechanism shown in the accompanying drawings, and hereinafter described and particularly claimed.

In the drawings, Figure 1 is a perspective view of my device attached to a bed and cylinder press. Fig. 2 is a detail of a bracket for supporting the inking apparatus. Fig. 3 is a top plan view of the frame and supplemental form with attached parts. Fig. 4 isa longitudinal vertical section on the line 4 4, Fig. 3. Fig. 5 is a transverse vertical section on the line 5 5, Fig. 3. Fig. 6 is a similar section on the line 6 6, Fig. 3. Fig. 7 is a top plan view of the frame with the supplemental form removed. Fig. 8 is a transverse vertical section of a modification. Fig. 9 a is top plan view of the same. Figs. 10, 11, 12, and 13 are details of modifications to be hereinafter referred to. Fig. 14 is a detail of the madification shown in Figs. 8 and 9.

In my present invention the supplemental form, A, is retained within the frame, 19, normally below type high so that the inking apparatus is to be so adjusted that its inking roller will dip below type high for inking the U supplemental form, instead of inking the said my chromatic printing device, C. This device consists of an open rectangular frame, 19, having inclined lugs, 20, projecting upwardly from the bottom and ribs 28. with fiat upper faces extending longitudinally of the frame. The supplemental form-holder, A, upon which an electrotype or plate is secured, has corresponding inclined lugs, 21, and ribs 28', with flat lower faces, depending therefrom,

adapted to engage the inclined lugs, 20, of the frame, so that as the form-holder is moved transversely of the frame it will also be caused to move vertically. upward until the flat faces of its lugs, 20, rest upon the ribs or projections, 28, of the frame, affording a firm base for the form-holder when animpression is taken, as is in my application before mentioned. A bell crank lever is pivoted at 40, on the frame, its two arms, 24 and 41 being in different horizontal planes, the formerengaging a slot in thespring actuated dog, 45, while the latter is connected to the form-holder by a pin, 39, projecting upwardly into a socket in the bottom of the form-holder. In the sides of the form-holder are guide ways, 23, into which the pins, 22, passing through the sides of the frame, 19, enter for the purpose of limiting the upward movement of the formholder and preventing its displacement from any cause. The side bar, 26, is detachably secured to the frame by a forked lug,25,which snugly holds the bar from any lateral movement. By making the side bar separable from the frame the latter can be readily locked within the main form at any portion of the column and the side bar easily adjusted, the

. space between it and the frame being filled in with ordinary printers side sticks.

It is to be understood, of course, that the supplemental form-holder is used at the side only of the main form, and so placed as to bring the rail, 29, and dog, 27, outside of the type line.

The side bar, 26, is provided with a slot, 27, in one end of which is journaled a roller, 37, upon which rests the inclined projection or cam, 38, on the front end of the dog, 45. This dog has on its rear end a slot, 31, through which the pivot pin, 32, passes, forming a fulcrum upon which the dog moves forward and upward, the forward movement being limited by the length of the slot. In its lower position the dog rests upon webs, 30, extending across the forward portion of the slot, 27, and into recesses in the lower face of the dog. A spring, 34, located in a slot, 36, of the dog, with one end engaging a pin, 33, on the side bar and the other in contact with the front end of the slot in the dog, tends to press the dog forward against the roller, 37, upon which the cam, 38, rides, thus normally holding the free end of the dog up and keeping the arm, 24, of the bell crank lever in its extreme forward position, thereby retaining the form-holder normally below type high. Upon the outer edge of the side bar is an elevated track or rail 29 for operating the roller, 42, on the end of an arm pivoted upon the frame, 13, of the inking apparatus, which arm carries at its opposite end the ink roller, 16, normally in contact with the main ink roller, 12, above which are the two distributive rollers, 14. The frames of this inking apparatus are provided with two clampingjaws, 9, which are secured upon the cross bar, 6, that is held in place between the clamping jaws, 11, of the bracket, 5, by the set screw, 7, said bracket being adjustably mounted upon the side frames of the press by suitable set screws, 10. In Fig. 1 the brackets are shown with the single clamping jaws, but it is obvious that there may be two or more such jaws, as shown in Fig. 2, if it is desired at any time to provide for more than one inking apparatus, located at different distances from theimpression cylinder.

In order to provide for the vertical adjustment of the inking apparatus, I make the brackets for supporting the cross bar, to which the frames of the inking apparatus are secured, as shown in Figs. 12 and 13, which illustrate my preferable construction of this feature of my device. In this modification the bracket, 5, terminates upwardly in a stem, 52, preferably circular in cross section, which is provided with a groove extendinglongitudinally of the stem, in the bottom of which groove is a rack, 53. A collar, 59, encircles this stem, and is held in place thereon by the screw threaded bolt, 55, passing through ears, (30, and to which bolt a handle, 56, is pivotally secured. Journaled in ears, 58, on the collar, 59, is a pinion, 54, meshing with the rack, 53, and on the shaft of which is a hand assess rotate in mesh with the rack, 53, thus moving I said collar up or down.

As the device passes under the inking apparatus the cam track, 29, engages the wheel, 42, thereby causing the roller at the opposite end of the arm, 52, on which the two are mounted to be depressed below type high and ink the form with ink fed from the reservoir, 18. Passing under the impression cylinder which is now above type there is no effect uponthesupplemental printing device. Upon the reversal of the bed, the impression cylinder, lowered to type high, engages the dog, 45, depressing it and causing the bell crank lever to move the supplemental form to type high for an impression.

In order to provide for the printing of colors in various widths without having to provide separate complete devices for the different widths,[ form the sides of the frame, 19, and the ribs, 28, detachable as shown in Fig. 11, the side frames being secured together by dovetail joints, 0., at the ends, and provided with mortises into which corresponding, tenons on the ends of the ribs, 28, are adapted to fit. The bottom of the frame in this construction will form a grid composed of the several ribs, 28. When it is desired therefore to alter the width of the color printing the frame can be readily dismantled, the side pieces of the proper length selected and the form readily assembled with the parts in the same relation as above described.

Between the edge of the frame and the point.

where the ink roller, 16, first strikes the plate or type upon the form-holder, there is considerable lost space, and to insure a proper inking of the whole of the supplemental form, and at the same time reduce this space to a minimum, I employ the construction shown in Fig. 10, where an enlarged view of a portion of the inking apparatus is shown.

Instead of employing a single roller upon the arm, 52, which is moved by the track or rail, 29, to ink the supplemental form, the roller, 16, is journaled in an upward extension of said arm, and a second ink roller, 44, of smaller diameter is journaled on the arm below said roller, 16, receiving ink from a metal roller, 43, rotating between the two. By this arrangement the roller, 44, can be caused to dip closely to the edge of the frame, and enter the form closer to the edge of the same than in the ordinary case where a single roller of larger diameter is used. Motion to the inking rollers is transmitted from the bed of the press by the friction wheel, 17, which should be in contact with the chase; but I do not wish to be restricted to this means of transmitting such motion, as in presses where the impression cylinder is provided with a Circular rack other suitable means maybe employed for this purpose.

In Figs. 8 and 9 I have shown a construction similar to that in the preceding figures with a supplemental form arranged to print acolored border or other matter around a contrastingcenter. The meansforaccomplishing this result consists of the centrally a-pertured form-holder, B, secured by posts, 47, passing through the vertically and horizontally movable plate, A, to a frame, 46, located between the inclined logs on the bottom of the frame, 19. The plate, A, is also provided with an aperture of sufficient diameter in the direction of its horizontal motion to allow of said motion without coming in contact with the form-holder, A The springs, 48, bearing between the frame, 46, and the plate, A, normally tend to keep the form-holder, B, seated upon the plate, A, below type-high. Two levers, 49 and 50, fulcrumed at the bottom of the frame 19, and connected by a pin, 51, upon one of the arms engaging a slot in the other, extend upwardly and support bya sliding contact the frame, 46. The lever, 49, is prolonged through slots or openings in the side bar, 26, and dog, 45, and is adapted to be pressed downward by any suitable means such as a shoe, a, secured to adownwardly projecte ing standard, 17, supported by the cross bar, 26, Fig. 14, so as to cause the upper'ends of the arms of the levers to raise the frame, 46, and

the attached form-holder, B, above type-high,'

and always carries its form at type-high so.

that the latter maybe inked by the main ink rollers. By this arrangement, it will be seen that two colors may beprinted by the same device, one either as a plain bordenaround the central electrotype or plate, in contrasting color, or either or both in letters, figures, &c., of different colors.
