INKING MECHANISM FOR MULTlCOLOR-PRINTING.

SPECIFICATION forming part of Letters Patent No. 639,247, dated December 19, 1899.

Application filed July 20, 1897 To all whom it may concern:

Be it known that I, ALBERT D. KENESTON, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented new and useful Improvements in Inking Mechanism for Multicolor-Printing, of which the following is a specification.

My invention relates to mechanism for distributing on an inking-roller inks of two or more colors for use for multicolor-printing; and it consists of the novel construction and combinations of the devices and elements hereinafter described, and pointed out in the claims.

The objects of my invention are to provide a printing-press with a simple mechanism which may be readily applied to the press for distributing two or more color-inks simultaneously on the same inking-cylinder; also, to provide mechanism by which the two or more color-ink rollers may be automatically moved longitudinally and reciprocatingly in contact with the same ink-distributing roller, and, further, to provide mechanism by means of which the length of reciproeating longitudinal movement of the two or more ink color rollers may be adjusted at the will of the operator, as may be predetermined.

Other objects and advantages of this fun vention will be fully understood from the following description and claims, when taken in connection with the annexed drawings, in which Figure 1 is a side elevation of a printingpress (a suitable portion thereof shown) having my invention applied thereto. Fig. 2 is a view taken in transverse section at line 1 in Fig. 1, with parts shown in section. Fig. 3 is a sectional view taken at line 2 in Fig. 1. Fig. 4 is a view of opposite end, taken at same line 2 in Fig. 2. Fig. 5 is a plan view of the ink-roller-shaft keeper; and Fig. 6 is a section taken at line 3 in Fig. 5.

Like letters of reference refer to like parts throughout the several views.

The drawings show so much of a printingpress of the kind known to the trade as the Universal as is deemed necessary for illustrating a press to which my invention may Serial No. 645,212. (No man.)

be applied. In the drawings, in this press, A is a portion of the frame of the press.

B is the revolving ink-cylinder.

C is the revolving crank-disk, mounted on the drive-shaft of the press, andD is the pitman intermediate between the crank-disk O and the platen, which latter and other parts of the press are not shown, their illustration being unnecessary for a full understanding ofmy invention.

E is a longitudinalreciprocating shaft haw ing mounted thereon two or more color-inkdistributing rollers F, adapted each to freely revolve independent of the others, yet simultaneously. This shaft E is cylindrical in form and of suitable thickness for stiffness and of length to include portion e between the bearings a a in the frame, and a suitable extension, as e, projected outward beyond one of said bearings a for reception of the reacting spring G, While the opposite end is provided with a suitable engaging device say as hook F-for holding the cord or chain, hereinafter described. The outer end of portion 6 is provided with the spring-keeper 6 which may be made of any suitable form and secured to said end by a pin or screw.

11 H are shaft-keepers suitably secured to the frame-pieces A at points adjacent the hearings to a for service as upper side bearing-pieces for preventing shaft E from rising from the bearings a. My preferred means for securing these keepers in place consists of a binding-bolt H, provided with nut H Although the form of these shaft keepers may be varied, yet I prefer to make their bodies 71. with an oblong form and each with a width corresponding with that of the slots a, leading to the bearings a and provided with lateral flanges h, Figs. 3, 4, 5, and 6, for bearing on the edge margin sides of slots at, as shown in Figs. 3 and 4, while theirlower ends are each provided with notch 7L2 for service as an upper-side bearing ofshaft E. These shaft-keepers are set in slots a in the frame and have their bearing ends 77. at such a distance from the bottoms of bearings a as to hold said shaft from rising and at the same time allow it to be freely moved longitudinally in either direction.

"The color-ink-distributing rollers F are preferably made of elastic composition, as generally employed by the trade, and are each mounted on an independent tubular shaft F, which is itself mounted on shaft E, so as to freely revolve thereon. Adjustable thimbles F provided each with set-screw f, are also provided on shaft E and are employed one at each end of each distributing-roller F, as shown in Fig. 2, for keeping the two or more of these rollers at their predetermined distance apart on shaft E. These ink-distributing rollers F F are employed in numbers corresponding with the number of color-inks to be distributed on the inking-cylinder B, whether two, three, or any other preferred number.

1, Figs. 2 and 4:, is a spring-guard arranged over the reacting spring G and shaft portion 6. This guard I is preferably made with an inverted-U form in its cross area for inclosing the upper and lateral sides of said spring G and the portion 6 of shaft E within said spring. This guard I is preferably integral with bracket 1', which is adapted to have its body portion 2' fit in slot a, leading to hearing a, while lateral flanges t are provided for bearing against the outer side edge margins of the said slot, as shown in Fig. 4, while the binding-bolt H, preferably secured to its adjoining shaft-keeper, rigidly secures said bracket with the frame at the same time said bolt secures the adjoining shaft-keeper in place.

J, Figs. 1 and 2, is a friction-roller bracket secured to the side frame opposite that to which the spring-guard I is secured. This bracket may be of any suitable form and be secured by any suitable means with such side frame, so as to adapt it to hold the frictionroller K in position with its peripheral groove on a line with the axis of shaft E for carrying a draft cord or chain from the engaging hook F to a suitable connecting-link, as will be hereinafter described. This bracket J has its attaching portion J fitting in slot at and provided with flangesjj for hearing against the outer edge margins of said slot and also with a perforation for receiving the bindingbolt H, by which this bracket is secured to the frame.

L is a link adjustably connected with linkkeeper M, which may be pivotally connected with the pitman D or any other suitable reciprocating piece directly or indirectly, as

may be preferred. This link L is provided at its upper end with a loop or hook Z for engagement with a flexible connection between said link and the shaft E, and it is provided below with a screw-threaded binding screw or bolt 1, provided with nut Z The link-keeper M is made with an oblong slot m and with guiding-flanges m m, be-

tween which flanges the body of the adjustable link is held by the binding device Z when said link has been adjusted longitudinally in relation to its keeper.

The link-keeper M may be pivoted directly with the pitman D in some presses, While in other presses it may be pivoted to some other reciprocating or moving device or part of the press or attachment thereto without departing from the spirit of this invention. When applied to the press of the class above mentioned, I prefer to clip pivot N to pitman D by means of clip 0, made sectional and of parts 0 0', held together by binding-screws 0 0 with one of the parts, as 0, having pivotN integral with it, so that said pivot may be readily applied at will to said pitman D at any preferred point in the length thereof, as may be found to be advantageous or most convenient. This pivot N receives the eye M, shown to be provided on the lower end of the link keeper M, which is secured thereon by means of nut N, screwing on the screwthreaded stem it, made with pivot N.

P is a flexible draft connection between link L and shaft E and is connected by one of its ends with hook or loop Z of the said link and by .its opposite end with the device or hook F of the said shaft E, while the body of this draft connection is carried by the friction-roller K. This draft connection P may be made of cord or chain, as may be preferred, and is guarded at the friction-roller by loop q of keeper Q, arranged at a suitable point over roller K, so as to allow the cord or chain to freely move through loop q and is held in place by the perforated limbs q q of said keeper Q and the pivot-pin 70, passing through the ears of the bracket J and friction-roller K.

WVhen the above described devices and parts are applied to the press, as above described, the adjustable link L will be adjusted in relation to its keeper M for lengthening or shortening the distance between pivot N and the flexible draft connection P for regulating the length of the longitudinal movement to be given to shaft E, which movement may thereby be varied from one-half of an inch to two inches or more, as may be preferred or be found to be advantageous for best results, and the higher link L is raised in the keeper above the pivot N the shorter will be the length of the movement of the shaft, while a lowering of the said link will effect a corresponding lengthening of such movement, and whether the movement of the shaft E be longer or shorter the flexible draft connection P will be more or less slack, and the length of its slack will be increased as the length of the movement of said shaft is decreased and be lessened when the movement of the latter is to be increased. I

In operation the downward pull of the connection P will move the shaft E and the several inking-rollers thereon longitudinally in one direction to the distance allowed by the adjustment of the link L in relation to its keeper M. Then the reacting spring G will operate to move said shaft and inking-rollers longitudinally in the reversed direction. In both these longitudinal movements of said shaft and inking-rollers thereon the latter will revolve in contact with the inking-cylinder B and transfer to it its proper proportion of colored ink, as before predetermined shall be distributed on said cylinder.
