THEODORE J. 'TURLEY, OF NASHVILLE, TENNESSEE.
CHROMATIC-PRINTING MACHINE.
SPECIFIGATIQN forming part of Letters Patent No. 508,067, dated November 7, 1893. Application filed December 31, 1892. Serial No. 456,864.. (No model.)
To aZ Z whom it may concern."
3e 11: known thatLTHnonoRE J. TURLEY, a cltizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Chromatic-Printing Machines, of which the following is a specification.
My invention relates to chromatic printing machines and has reference more particularly to that class of machines in which a rotary form or type cylinder is employed.
In the drawings Figure 1 is an end view of a type cylinder, partly in section, showing my improvements applied thereto; Fig. 2 a side View of the same, partly in section; Figs. 3 and 4 sectional views, on a larger scale, showing certain details of construction; and Fig. 5 a diagrammatic view.
A indicates the type cylinder of an ordinary perfecting press; B the shaft of said cyl- 1nder; and O a portion of the frame of the machine.
D indicates a second shaft, parallel to shaft B, and journaled in suitable bearings or supports inside the cylinder. At one end, outside the cylinder, this shaft is provided with a plnion E to mesh with a second pinion F mounted upon the shaft B. It willbe noticed however upon reference to Figs. 1 and 2, that one side of the hub of this pinion F, is flattened, as at F, where it is seated in the frame, so that said pinion will remain stationary at all times. I do not wish to restrict myself to this specific construction as obviously any other suitable means may be employed to hold the pinion against rotation.
Secured rigidly upon the shaft D, withinthe cylinder, are two cams G and H of different throw, which are designed to act successlvely upon a form-block or form-holder I as shown; the said cam G having a less throw than the cam II. This form-holder I, which carries the type or form to print in color, works radially through the periphery of the cylinder; a suitable opening K being made to permit the holder to move freely therethrough to brlng its printing surface above, even with, or below the printing surface of the cylinder. On the inner face of the cylinder, around the opening K is a box or housing J open at its lower-end to permit the form-holder to proj ect therethrough in position to be acted upon by the cams. The side walls of the box or housing project toward each other at their inner ends, as shown in Figs. 1 and 3, to form a tapering seat or socket to receive the inner end of the form-holder which is correspondingly tapered. In each end wall of the box or housing J, are two slots at a, into which project the pins b b on the ends of the holder I as shown; this pin and slot connection insuring the movement of the holder in a right line. The end walls of the form holder are slotted or recessed as at c and in these recesses are mounted coiled springs L,Figs. 3 and 4,which are secured at their upper ends to the holder I and at their lower ends to the lugs d which project from the housing J into the slots or recesses c; the said springstending to draw and hold the form-holder inward in contact with the cams, and, under certain conditions, to draw the form-holder inward until its outer face shall be below the printing face of the cylinder.
7 The operation of the mechanism is as follows; assuming that an impression has just been made and that the cylinder is turning to the right. As the cylinder continues to travel, the shaftD carried by the cylinder, is caused through the gearing E F to turn in the same direction, with the result that the shorter cam G is removed from beneath the form-holder and thelonger cam H'brought beneath the latter. While the form-holder was supported by the cam G (which in order to give steadiness to the form-holder comprises two separated cams or arms) the printing face of the matter carried by the formholder was in line with the printing face of the stereotyped matter on the cylinder; but the instant that the cam H is brought beneath the form-holder, the latter is raised or moved outwardly above the periphery of the cylinder, as shown in Figs. 3, land 5. While held in this position by the cam H, the matter carried by the form-holder is inked in any desired color by the roller M which is so set or adjusted as not to ink those portions of the form which it is desired to ink black-with,
the ordinary rollers N. After passing beneath the color roller M, the camI-I is withdrawn from beneath the forn1-ho1der, and the springs L draw the latter inward below the periphery of the cylinder as indicated by the dotted lines in Fig. 3, (and by O in Fig. 5) so that the matter carried by the holder I will not be inked black by the rollers N N. After the form-holder passes these rollers, the cam G is brought beneath it and forces it into the position shown in Figs. 1 and 2, (and by P in Fig. 5;) and holds the form holder in printing position preliminary to taking an impression.
It is obvious that instead of using the separate cams and the springs, a single cam may be used to move the form holder positively into the three positions noted.
