PRINTING-MACHINE.

srncrrroamon forming part of Letters Patent No. 74 7,694, dated December 22, 1903.

Application filed March 20, 190 3. Serial No. 148,715. \NQ model.) 4

To all'whom it may concern:

Be it known that I, CHAUNCEY VV..GAY,'a citizen of the United States of America, and a'residen-t of West Springfield, in the county of Ham pden and State of Massachusetts,-have invented certain new and useful Improvements in Machines for Making and Printing Blanks for Cartons or otherPnrposes,of which the following is a full, clear, and exactdescription.

This invention relates to improvements in printing-machines, and more especially to that class thereof which comprise a comparatively large cylinder which serves as acarrier andplaten upon which the printing is performed, one or more printing-cylinders combined with 'the carrier-cylinder,devices for feeding the blanks to the carrier-cylinder, and means on thelatter for holding the blanks thereon in readiness for and during the printing operation. 2

An object of the invention is to provide a new arrangement or organization of the machine, so that the printing cylinder or roller, or usually several thereof, coacting with the carrier and impression-faced cylinder may be inked more than once for each printing operationof each printing-cylinder in conjunction with the relatively adjacent peripheral impression-surfaces of the carrier-cylinder, whereby printing-inks of thinner character and susceptible of better andmore uniform'distrihution may be employed and usedby superimposition on the printing-cylinder for better printing results than would be the case were the printing-cylinders each subjected to but one ink-supplying rolling contact around its printing face by the ink-supplying roll or rolls for its each and every printing operation. V

A further object of the invention is to so organize the machine that it is possible to feed the blanks from a horizontal orotherwise suitably-disposed feed-table having its surface and the feeding-plane non-tangential to the carrier and impression-faced cylinder, but, on the other-hand, in a plane which is approximately coincident with theaxis of rotation of the c; linder impressiOn faced carrier or platen, the blanks edgewise approaching the body of the platen-cylinderabcut perpendicularly thereto, permitting a successful op- 'usiu flies or carrier-ta es in con 'unction with the carrier-cylinder; and a further ob ing figure.

frames in which the several component ele- Y ject of the invention is t0 organize and arrange the parts of the machine in a manner to acquire in a most simple and inexpensive manner efficient printing in one or as many colors as desired and in' perfect registry at a maximum speed.

The invention consists in combinations or arrangements of parts and the construction of certain of the:pa'rts, all substantially as hereinafter fully described, and set forth in the claims.

In the accompanying drawings, in which a a machine is illustrated embodying the present improvements, Figurel is substantially I a'plan view, the carrier or platen cylinder being represented in horizontal section on the plane of its axis, some parts, understood as located above such plane, being absent, Fig. 2 is a central vertical longitudinal section of the machine. Fig. 3 is a side elevation, on a larger scale, of a portion of the carrier-cylinder-and cooperative rolls and devices. Fig. 4 is a perspective representation of some of the parts especially included in the preced- In the drawings, 20 2 1 are suitable side ments of'the machine are supported, and

which are properly distanced by ties 22 23.

Secured to the frames 20 21 are brackets sitioned. The blanks may be fed one at a time onto the table 26 from a shelf 27 and between feed-rolls 28 29 to drop onto the table 26, where each blank will be positioned for proper presentation to the printing mechanism. The means for-positioning the blank comprise, preferably, a guide-plate 31, which may be stati'onaryand at the same time adjustable laterally of the table 26, and cooperative with the guide-plate 31 are placing or jogging pins 32, mounted for iiiovement toward and away from the plate 3l-as, for instance, by a yoke 33to whichreciprocatory movement may be imparted bnjgui-derods 34 by a link 35, pivotally sccu red on the yoke 33, and having its other end adj ustably secured to one arm of an angle-lever 36, which is pivoted at 37, and the other arm of which is connected through a link 38 with a lever 39, secured upon arock-shaft 40. The blank is in this .manner properly positioned laterally of the table, and means are provided for advancing the blank toward the further feeding devices for the required distance and at the proper time, these means comprising, in the form thereof shown, a yoke 41, having pinsv 42, and slidably supported on guide-' rods 43, on which said yoke may be reciprocated by a link 44, connected with an arm 45 at any one of a series of adjusting-holes 46, so that the advanced position of the leading blank end may be regulated as desired. The arm 45 is shown as secured on the rock-shaft 40, above mentioned, and which shaft may be oscillated by an arm 47, connected by a link 48 with a crank-pin 49, secured on a spurgear 50, journaled on the bracket 25 and retated by a pinion 51 on a shaft 52. Mounted on the shaft 52 is a roller 53, serving as a support for the blank during its feeding movement toward the carrier, and with which cooperates a roll or drum 57, mounted on a shaft 54, journaled in the frame, both such rollers being rotated simultaneously and for uniform peripheral speed in the direction of the arrows by suitable gearing. The blank is led toward and maintained in proper position relatively to the carrier-cylinder '76, which serves as a platen-support therefor, until it has been printed in one or several colors, as may be required. Means are provided for seizing and holding the leading end of the blank on the carrier 76, these means comprising gripper-fingers 77, mounted on a shaft 78, having at one end arm 79, the roller of which is adapted to engage a preferably stationary eam 81, whereby the fingers 77 are opened and against the action of a spring 82. The present carrier-cylinder 76 is of such size as to have a capacity of two blanks for each rotation, so that the blankgripping fingers are'provided in duplicate.

In connection with the construction and action of the roll 57 and carrier 76 it is to be noted that these parts have the longitudinallyextending crescentshaped depressions or comparatively large grooves or recesses 19 to give space for occupancy of the grippers and the portion of the blank manipulated thereby within the contours of the peripheries of these parts, and the lower roll 53 is likewise formed with its wall along one side rentrant to permit its proper cooperation with the grippercarrying drum. In order that the grippers, which are located within the recesses in the respective cylindrical parts adjacent the junction of the wall of the recess with the adjacent peripheral portion, may have their proper opening and closing movements through courses which are outside of the peripheral contour of the carrier-cylinder 76 and the roll 57, such parts are constituted with respective series of niches 83, arranged along the lengths thereof at the junctions of the walls of the recesses and the peripheries, the niches in the carrier-cylinder 76 being relatively opposite the gripper-fingers of the roll 57 while the niches in the roll 57 are relatively opposite the gripper-fingers of the carrier-cylinder, such niches of course being ofiset as the one set thereof is related to the other set.

The grippers 66, provided as equipments to the roll 57, are mounted upon the small rockshaft 67, which is journaled in end plates 68, affixed on the ends of said roll, and said shaft is provided with an arm 69, having a roller 70, adapted for engagement with a cam 71, (see Fig. 3,) which is understood as stationary and sustained on a suitable supporting part of the machine adjacent the end of the said roll and serving to open the grippers, while a spring 72 is operable to close the same.

The particular method of transferring the blank from the roll 57 to the carrier is clearly indicated in Figs. 3 and 4, in which the roller 80 is substantially free of the opening-cam 81 to permit the spring 82 to impinge the finger 77 on the leading end of the blank and preparatory to its release from the grippers 66 of the scoring-drum, whereupon the grippers 66 are operated by the roller 70, engaging the stationary cam 71, to release the blank, as shown in Fig. 3. After the blank has been brought to and moved partially through the pair of rolls 57 53 it will be carried along by the rotating carriercylinder 76, which is shown as formed with alternate impressionsurfaces 84 and recessed or relieved portions 85, the former of which are covered with tympans 86, as common, held thereon in any suitable manner and constitute the blanksupportiug and impression faces of the carrier, while the relieved portions will clear the several printing-cylinders, to which the blank is successively subjected. The blank released by the grippers of the roll 57 and taken by the grippers of the carrier-cylinder '76 and movable around on and with the upper hemicylindrical portion of the said carrier-cylinder is carried thereby, subject to the printing action of one or more ink-printing rolls 111, arranged axially parallel with and in peripheral proximity to the prominent or impression-surface portions of the carrier, each said printing-roller having combined therewithink-supplying and ink-distributing rollers of a common and approved construction and arrangement. The organization is such that the diameter of each of the printing-rollers 111 is fractional of the diameter of the carrier-cylinder, and the peripherallength of the impression-face 84 is equal to the complete circumference of the printing-face portion of the printing-cylinder, the vacancy or recess between the impression-surfaces 84 be ing likewise equal to the circumferential extent of the printing-roller, so that for each printing operation that is, during the time of printing against the impression-surface or platen-section 84 and during the time of transit under the printing-roll of the properly structed four times the diameter of each of the printing-rolls 111, is provided with dia-' metrically opposite sets of grippers, each set thereof being at the initial end of diametrically opposite prominent impression-surfaces 84, each of which has a peripheral extent equal to one-quarter of the circumference of the large cylinder,-and both being separated by a vacancy or relieved or recessed portion of equal length to that of the impression-surface portion, and allof the printing-rolls have their locations above and contiguous to the upper half of the carrier-cylinder.

A peculiarity noticeable in the action of this machine is that the blanks are fed in a plane approximately coincident with the axis of the carrier-cylinder 76, the arrangement of the paired rolls 57 and 53 relatively to the larger cylinder enabling the blanks to approach toward the carrier-cylinder perpendicularly or substantially squarely -at the middle of its body,.and the management of the blank, while being subjected to the printing or printings thereon, is during the time.

sired portion of the impression-surface, ac-

cordingly as the blank maybe larger or smaller, and no other confining or retaining means than the said grippers at the leading end are required, the blank remaining by its gravity smoothly in place upon the impression-surface of the carrier, and of course its successive printings which may be performed while the blank is making a half of a cycle will be in perfect register; and from the foregoing it will be manifest that this machine may be successfully ru 11, with greater rapidity doing multicolor printing work without the.

employmentof any flies carrying or retaining tapes or retaining springs in conjunction with the carrier-cylinder, and the entire sur-,

larger carrier-cylinder may be employed, the multiple of its diameter being greater than a four-fold one corresponding to the printingroller or multiplied printing-rollers, so that a carrier might comprise three, four, or more relatively intermediate vacancies with respectively provided grippersvand ,gripper-actuating devices, the printing-rollers, however,

having their locations only at and in operative proximity to an upper portion of the carrier-cylinder.

After each blank is printed as described the carrier will convey it toward the delivery table 'seasonably and near whichpointthe sets of alternatingimpression-surfaces and v gripper 77 will be opened to release the blank,

which may then drop or slide onto a receiver therefor, a receiver here being represented as constituted by a board 113, removablysupported on one or more belts 114, constituting a continuously-advancing apron and support pulleys 115 and 116, on shafts 117and v118, respectively, which are suitably journaled on the side frames of the machine. lhe shaft 118 is represented as driven by a worm-gear 119, mounted thereon and engaged by a worm 120, secured to a shaft 121,-also journaled in the side frames and obtaining rotary movement through a pulley 122, mounted upon the other end thereof, and operative by a belt 123 from the pulley 124, which is'mounted upon nor the movement ofthe belts 114 will be the main driving-shaft 97, so that in this man- ,IOO

comparatively slow but uniform during the I rotation of the carrier. In consequence of this movement the blanks will as they successively leave the carrier overlap each other on the receiving-board 113, and will, furthermore, be positioned thereon with their lower edges against a gage-board 125, which is preferably adjustably secured to a frame 126, so

as to adapt the same for difierent lengths of blanks. After the board 113 has received blanks up to its capacity it may be removed from the belts 114 without in any way-di'sturbing the blanks thereon, therefore avoiding all liability of blurring the freshly-printed surfaces thereon, while at the same time they parts, it is not to be understood that I claim any novelty in the combination of cylinders or rolls with grippers and with gripper-actuating means, for I am aware that such are old, and the forms of the grippers and the actuat ng means therefor which I employ are or may be ofsubstantially the same character as hereinafter known and used;
