PRINTING PRESS.

Application filed July 2, 1923. Serial No. 648,957.

The invention relates to printing presses, and more especiallyto novel and. useful improvements in printing press inking mechanisms.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the

same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illus-- trate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings Fig. 1 is a fragmentary, side elevation of the inking mechanism of a printing press;

Fig. 2 is an enlarged fragmentary detail of the position regulating means applied to the form inking rollers;

Fig. 3 is a fragmentary section taken substantially on the line 33 of Fig. 2;

Fig. 1 is a fragmentary enlarged elevation of another form of position regulating means applied to the inking rolls;

Fig. 5 is a fragmentary horizontal section taken substantially on the line 5-5 of Fig. 4; and

Fig. 6 is a diagrammatic view correspond- 'ing to Fig. 1. p

The invention is principally and prima- .rily directed to more efiicient and uniform inking action, especially in connection with high speed rotary printing. In certain of its features, it is. directed more especially to effecting these results in connection with form cylinders of printing couples adapted .to be rotated in both directions, depending upon the nature or kind of product desired.

The objects and advantages are attained by my invention through the relative position, sizes or proportions, and other characteristics of the ink drums, ink rollers, and other members of the inking system w'th respect to each other, with respect to the form cylinder, and also to its two directions of rotation. Cooperatingwith the foreg0-- ing are-means for nicely and accurately positioning the form rollers and other'inking rollers relatively to the impression cylinders, the inking drums and other devices and mechanisms.

Other features of the invention will be set forth primarily in connection with the following detailed description of the present preferred embodiment; and it will be understood that the preceding general description and the following detailed description are,

form, and may be either continuously or in.

termittently rotated. Any suitable device 4- for regulating the ink supply from the fountain to the roller 3 may also be provided.

A ductor roller 5 reciprocates or oscillates intermittently between the fountain roller 3 and an ink drum 6, which may be styled the receiving drum as it first receives the ink from the ductor roll. The ductor roller is journaled in the top end of a pair of arms 7, which are fixed to a shaft 8, journaled in the side frames 1 of the machine. Fixedto the shaft 8 is an actuating arm 9,

having acam roller 10 running on a rotating cam 11. The cam is fixed on a shaft 12, which is journaled in the printing press frame 1. Suitable devices for regulating the. position and action of the ductor roller 5 relatively to the fountain rollerB and ink drum 6 are provided, and as shown, these devices 13 are'interposed between. the shaft 8- and the roller 10', and likewise may be of any known or suitable form. A suitable spring (not shown) is usually employed to yieldingly impel the ductor roller am the fountain roller and to keep'the rollerlOto its cam 11.

The ink drum 6 has a shaft 14 journaled in the side frames 1 of the press, and. it is driven by suitable gearingor other means of any known or convenient .form, and is preferably non-vibratmg.

In accordance with one feature of the invention there are separate trains'of ink pre-.

paring and conveying devices to the form cylinder, each of these trains having various features and characteristics directed to eilidriven and preferably vibrated. The relacient inking action, and to effect such action tive proportion of the drum 30 to the drum for either direction'of rotation of the form 26 may be considerably different from that cylinder. of the drum 26 to the drum 6.

As embodied, and referring primarily to The vibrating ink roller is located above the upper train of inking devices, an inking the line of centers of its coacting inking roller 25 cooperates with ink drum 6 and drums and this is true to even a larger dowith an ink drum 26, which drum has its gree with respect to the stationary inking shaft 27 journaled in the machine frame. roller 29.

There is also positive assurance that the Inking roller 29 .is preffirst inking to the plates on form cylinder.

A form inking roller 52 is likewise prefwhen it is rotating in the counter clockwise direction.

The same general statements at to proportions, general position and the like which have been made in connection with the upper'train of rollers and drums applies also to this series, including the explanation that on successive rotations a new part or element of each drum and cylinder comes in contact with the coacting roller or drum and so on indefinitely.

Referring now in detail to the positioning means for the ink rollers, both stationary and vibrating, shown in Figs. 4 and 5 of the drawings, the various shafts thereof have a bearing 61 at either side, formed at the end of a corresponding bar or plate 62. The bar or plate 62 is provided with an elongated slot 63, through which projects a clamping screw bolt 64:, which is screw- 25 threaded into the press frame 1. Contacting with the end of the plate or bar 62 is the turning head 65 of a screw 66, which-is screw-threaded into a tapped lug 64 formed on the press frame 1. 30 On its right-hand side, bar or plate 62' is in engagement with the turning head of a screw 71, which is screWJhreaded into a tapped lug 72 formed on the press frame. On its left-hand side, the bar or plate 62 is in engagement with the turning head 74 of a screw 75 which is screwed into a tapped lug 76 formed on the press frame 1. Thus the position of the inking roller may be regulated so that it may be made to press more heavily or more lightly against the inking drum at either side, or may be made to press either more lightly or heavily against both of the inking drums without .chan ging its relative coaction with either.

Referring now to the position regulating means for the form inking rollers (Figs. 2 .and 3), the shaft '80 of each form inking roller is journaled in a bearing 81, at either end thereof, the'bearings 81 being carried at the ends of corresponding bars or plates 82 .1 at either side of the press. Each bar or plate 82 isnested in, and is longitudinally reciprocable in, a correspondingly-shaped guideway in a plate'85. Each bar or plate 82 has an elongated slot 83 therein a clamping screw. bolt 84 projecting,therethroughand being screw-threaded into the plate 85.

For the purpose of longitudinally posi-' tioning the plate or bar 82 relatively to" its 60 supportin plate 85, a screw rod 89 is screwthreaded into the plate 82, and is rotatably journaled in 3. lug 90 formed on an extension 91 ofthe plate 85. A collar 92 on one side of the lug 90, and the turning head 93 on the other side thereof, holds the screw rod 89 longitudinally in position, and by turning it, the plate 82 may be slidto and fro along its guideway and be held accurately in any desired position.

The embodied form of means for positioning the form-inking roller relatively to its inking drum, comprises an elongated and preferably arcuate slot 97 formed in the plate 85, a. screw-bolt 98 projecting therethrough and being screw-threaded in base 99, whichbase is fixed .to the press frame 1 in any suitable manner as by machinescrews 100. Abutting against the righthand side or edge of the plate in Fig. 2 is the turning head 104 of a screw 105,

which is screw-threaded into a lug 106' formed on the press frame 1. A turning head 107 of a screw 108 abuts against the left-hand side of the plate 85 in Fig. 2, the

screw-rod being screw-threaded into a lug 109.

formed on the machine frame. Thus there is.

likewise either simultaneous or independent relative position of the form inking rollers relatively to the form cylinder or to the. coacting inking drum, the positioning transversely being substantially on a radiusfrom I the center of the-form cylinder. v
