PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 574,206, dated December 29, 1896.

Application'filed January 25, 1893. Serial No. 459,736. (N model.)

To all whom it may concern:

Be it known that I, ROBERT MIEHLE,0f Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements inPrinting-Presses; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

IO which form a part of this specification.

This invention relates to inking apparatus for cylinder-presses, and is applicable more particularly to the inking rollers of such presses.

r 5 As is Well known the composition surfaces of the inking-rollers rapidly accumulate dirt and floating particles, necessitating frequent renewals and consequent loss of time.

The present invention is designed to facili- 2o tate the renewal or exchange of these inkingrollers, and to this end it embraces devices by which the distributing-roll may be readily handled by a single attendant from one side of the press.

The invention consists in the matters hereinafter described, and pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan View of a part of a cylinder-press embodying my improvements. Fig. 2 is a sectional elevation of the same, looking toward the front side of the press, taken on line 2 2 of Fig. 1, the shaft of the distributing-roller being shown in section. Fig. 3 is an eleva- 3 5 tion of the same, looking toward the rear side of the press.

In the drawings, A represents the frame of the press, to the opposite sides of which are secured the longitudinally-adjustable plates B, each of which carries a vertically-ad j ustable shank B, terminating at the top in open boxes I) for the reception of the spindles d of the form-rollers D in the usual manner.

Secured to the opposite sides of the press, between the bearing of the form-rollers, are

standards E E, provided at their upper ends with seats or bearings e, in which the ends of the shaft f of the distributing-roll F are j ournaled.

5o Adjacent to the standards E E are other standards G G, having hearings in which .tributing-roll (shown in dotted lines) in case it is desired to use one in securing extreme evenness of distribution of the ink. Such other distributing-roll is commonly made'of composition like that of the inking-rolls. The shaft H is further provided at the rear side of the machine outside of the roll-bearings with an arm I1 which usually stands in an approximately horizontal position with its free end beneath the end of the shaftf of the distributing-roll, which shaft extends beyond its bearing a distance sufficient to engage the arm. Said arm H is preferably curved or provided with an upturned end to prevent the escape of the shaft from the same, as will hereinafter more fully appear. The rock-shaft H is further provided at the front side of the press with a crank or handlever h, which may be grasped by the operator for actuating the rock-shaft. The said crank rests normallyin engagementwith the upper end of a detent I, pivoted at its lower end to the side of the frame, as shown in Fig.

2. The detent I is provided near its upper end with a finger i, the purpose of which will be hereinafter explained.

The sides of the arms H nearest the standards E E are provided with recesses 71, 17. or, in other words. the arms are caused to form goosenecks, said recesses being designed when the arms are thrown back by the depression of the handle h to receive and support the ends of the shaft of the distributingroll F, as shown in dotted lines, Figs. 2 and 3, and to permit the ready removal of the same when occasion requires.

In operation, when it is desired to remove and replace rollers the operator releases the detent I and depresses the handle h, which, rotating the shaft H, will cause the free ends [00 of the arms H from the shaft F and cause the outer curved end of the arm H to lift the rear end of the shaft f and guide it as thearm rises into the recesses 7r of the arm II at the rear side of the press, the other end meanwhile being grasped by the operator and seated in the recess of the other arm II. In this way the clistributing-roll is supported upon the press, but at a distance from the form-inking rolls, thus leaving them free to be removed and replaced by clean-surfaced rolls.

In replacing the shaftf in its bearings the crank-handle is operated in the opposite direction or raised, the shaft being supported in the recesses of the arms II H until the outer curved end of the arm II has nearly reached the level of the bearing eon that side of the press. The front end of shaft f is then transferred to its bearing by hand, while by a continued movement of the crank the other end of the shaft will be restored to its bearing by the arm I1 and the further movement of the handle replaces the caps 71/. The detent I being engaged with the crank the shaft f is secured against accidental displacement.

A longitudinal rack K is secured to the bed of the press at the rear side, with which a pinion Ii, mounted on a stub-shaft Z, secured to the standard E, engages, the pinion L in turn meshing with a pinion f, carried by the shaft f, and actuating the distributing-roll F positively, as is usual in similar presses, the roller being also shifted longitudinally to more perfectly distribute the ink by means of a lever M, actuated from some moving part of the press and provided at its upper end with a friction'roll n2, engaging between two flanges f on the front end of the shaft f.

When the supplementary or riding distributing-roll is on the press, the handle 71, when operated as before stated, may be caught by the finger 1' of the detent I, thus holding arm 11 in such position that both of the distributing-rolls will be supported by said arms clear of the fornrrollers.

In the particular construction shown the arms II II are provided with spurs or projections 72 71 which serve to give such shape to the recesses or inwardly-cum ed parts of the goosenecks that they will properly support the distributing-roller shaftf when the crank is engaged with the said finger I". The presence of such projections is not essential, however, as the arms I themselves may obviously be so shaped as to secure the desired result without the use of the projections referred to as a distinctive feature.

In addition to its use in removing and replacing the form-inking rollers the device described is of great convenience for lifting and holding the distributing-roller clear of the inking-rollers when the press is not in use, so as to avoid distortion of the composition inking-rollers, which is liable to occur if the distributing-roller remains long in contact therewith.

It will be understood that I do not wish to be limited strictly to the details of construetion hereinbefore described, as many modifications thereof may be made without departing from the spirit of my invention. For instance, the arms II and II may be made in one piece, or the one secured to the other instead of to the rock-shaft. Furthermore, the crank-handle may be replaced with a handwheel or other equivalent device, and another appropriate form of lock or step may be used to perform the functions of the detent I; also, if preferred, an arm 11 may be used at each end of the shaft II, though I deem this unnecessary, and, indeed, I contemplate in some instances dispensing with the arm 11 described.

The features of construction herein described as applied to the form-rollers of a press may also obviously be used in connection with the ink-distributing rollers when the latter are provided with riding rollers.

\Vhile I have shown my invention as applied to a press in which the inking-rollers are arranged in pairs and one distributing-roller acts on two adjacent inking-rollers, yet the same features of construction may be applied with the same general advantages to presses having a single inking roller or rollers and a distributing-roller over each inking-roller.
