INKING MECHANISM FO'R' PRINTING PRESSES.

T 0 all whom it may concern Be it known that we, EDWARD R. LINE BAUGH and MARTIN I-I. STENDER, citizens of the United States, and residents of Barberton, in the county of Summit and State of Ohio, have invented certain new and-useful Improvements in Inking Mechanism for Printing Presses, of whichthe following is a specification.

This invention relates to inking mechanism for printing presses, and more especially the kind of presses wherein associated inking-and distributor rollers arecooperatively arranged in relation to an ink-distrib uting disk and a type form. In presses of the kind mentioned the distributor roller is mounted to rotate in peripheral contact with a pair of inking rollers, and the associated rollers are borne by a swinging frame which is so constructed and arranged as to carry the rollers through a path wherein the inking rollers travel'upon the type form and the inking surface of the disk. The distributor roller has combined therewith screw and nut mechanism which is constructed and actuated to impart a single longitudinal impulse to the roller during each succeeding stroke of the associated rollers in order to effect the distribution of the ink on the peripheries of the inking rollers. Such mechanism is expensive; it requires nice fitting and adjustment, and it soon gets out of order.

The object of our invention is to'provide a motion' transmitting mechanism of simple and eflicient construction between the swinging frame and the'distributor roller, whereby several longitudinal impulses are imparted to the distributor roller during each succeeding stroke of the frame, and in consequence a better distribution of the ink on the inking rollers than formerly is accomplished,

as will be hereinafter described and claimed.

In the drawings Figure 1 is a side elevation, partially in dotted outline, of a portionof a style of printing press equipped with inking mechanism embodying the principle of our invention.

Fig. 2 is an enlarged view of one end of the associated ink distributor and inking rollers, and their connections with the swinging frame.

Fig. 5 is a longitudinal-section of one end Ofthe distributor roller and of its shaft, showing one of the adjustable end stops for Fig. 6 is a perspective view of the distr-ibu tor roller and its shaft.

Fig. 7 is a similar viewofone end of the associated rollers and; their supporting saddle, showing the bell-crank connection which is included in the mechanism for reciprocating the distributor roller.

Referring to the drawings, 10 designates the stationary main frame of atypical printing press, and 11 the oscillatory bed frame thereon, which latterframe supports the type-form at 12; and also the relatively in clined ink-distributing disk 13 and the inking devices and their appurtenances. Such inking devices include an ink fountain 14 arranged to overhang the upper path of the disk; a'roller 15 for said fountain; a pair of inking rollers 16; a distributor r0ller'17 in peripheral contactwith the latter, a nda single inking roller 18 below'the roller 16. The V rollers 16' are borne in spaced parallel relation to each other by saddles 19 which are located at each side of the press. Each saddle is pivotally connected to the outer end of a longitudinally reciprocative rod 20 that is slidably mounted on the adjacent side inember 21 of a. swinging frame pivotally supported on the bed frame 11. Only one of the saddles and its operating. rod are shown. The lower roller 18 is supported at each end by a hook saddle 22 which is also connected with a reciprocative rod 23 mounted in the adjacent frame member 21. The rods 20, 23

are normally retracted by means of suitably disposed springs, as 24, thereon, and the various elements are so co-operatively arranged that during the oscillation of the frame 21 the respective saddles and their rollers 'are swungupwardly and rearwardly and back again 1n such a manner that the inking rollers traverse the type-form and V the inking surface of the disk. The upper roller. of the pair as it reaches the limit of its rearward movement impinges against the fountain roller 15 and takes ink therefrom, which ink in the next su'cceedingforward movement of the frame 21 and its accessories is transferred to the rollers 16, which, in turn, distribute the ink on the surface of the disk.

In the oscillatory travel of the roller-car rying frame 21 the inking rollers are maintained in yielding contact with the opposing type-form and with the inking surface of the disk, by the retractive force of the springs on the respective rods 20, said rods being longitudinally moved in the respective frame members in accordance with the varying outward and inward distances of the rollers in respect to the axis of oscillation of the frame. The foregoing described mechanism being generally old, it requires no detailed description herein.

In the preferred form of our invention herein illustrated the distributor roller 17 is loosely mounted on a shaft 25 having at each end a polygonal end portion 26 which is mounted in a bearing bracket 27 on the adjacent saddle 19. The roller 17 is adjustably positioned for rotation on the shaft by end stops comprising split screw heads 23 which are clamped on the shaft and at the respective ends of the roller by means of nuts 29 on the heads. The bracket 2? has an opening therethrough which receives the end portion of the shaft, such opening being of appropriate size and form to permit movement of the shaft transversely as well as longitudinally of its axis. In the bracket is a suitably-disposed plunger 30 which is pressed against the opposed shaft portion 26 by the confined spring 31, the distributor roller thus being held yieldingly in peripheral contact with the inking rollers 16. One end of the shaft is provided with a bifurcated member 32 which embraces an arm 33 of a bell-crank lever and thus constitutes a. lever engaging men'iber. This lever is fulcrumed, as at 34:, on a block member 35 loose on an elongated pivot stud 36 which connects the adjacent saddle 19 with its rod 20, Loose on the stud is one end of link 37 which is pivotally connected at its op posite end to a rock-ar1n 38, fulcrumed, as at 39, on. the adjacent frame member 21. The rock-arm is connected by means of a link with the other arm, ll, of the bellc-rank lever, which link is preferably made in two parts adjustabl y connected. by means of a screw turn-buckle 42.

The foregoing described lever and link connections constitute motion transmitting mechanism between the swinging frame and the distributor roller, whereby, during the effective travel of the said frame and the resulting longitudinal reciprocation of the rod 20 having the elongated stud connection with the adjacent saddle 19, the rock-arm 38 is oscillated and the motion is positively transmitted therefrom by means of the link 4&0 to the crank-lever, which lever, in turn, effects longitudinal reciprocation of the distributor 1,495,eoe

roller upon the peripheries of the inking rollers 16. Owing to the various longitudinal movements of the rod 20 during its travel with the frame member 21 several recipr cative impulses of the distributor roller along the inking rollers are effected, such impulses, in the construction illustrated, being four times as often as when the distributor roller is moved by the screw and nut devices previously employed, and, in consequence, a better distribution than formerly of the ink is ensured, which result is particularly desirable on jobs requiring heavy ml:- ing.

It is to be noted that the acting arm of the bellcrank lever is made relatively broad to ensure its continued effective engagement with the bifurcated member 32 at various points and thus compensate for the different angular positions assumed by such arm and the rollerbearing saddle during their travel with the frame 21.

Our invention is not limited to the specific details of construction herein disclosed as the mechanism may be modified within the principle of the invention and the scope of the appended claims.
