ADJUSTABLE INKING- GEAR.

remesa.

Application filed February 23, 1912.

To all whom/1f may concern Be it known that I, CALVIN MARTIN, a citizen of the United States, residing at Peabody, county of Essex, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Adjustable Inking-Gear, of which the following is a specification.

rIhis invention relates to adjustable running gear and inking-rolls as applied to printing machines, and, more especially, to those machines which are used for printing ticket slips for theaters, soda checks, etc.

The object of my invention is to provide means whereby a series of inking rolls may be so adjusted or set that any one of them can be replaced without necessitating resetting of the series.

In order to distribute the ink evenly over the type or electroplate which is used in making the printed impressions, a number of careful adjustments are usually necessary which require the services of an expert and considerable time. lWhenever one or more of the inking rolls is worn out or needs replacement, it has heretofore been the custom to employ the services of this expert to again adjust the series as before. With my device, one setting suffices for every position of the ink plates or type, the new ink-rolls being mechanically guided into the same relation with the type as those which have been removed. Under my invention the necessarily frequent changing of an ink-roll is a comparatively simple matter and where readjust-ment is not necessary, the task can be performed by an unskilled operative. There is another adjustment which is related to that just described and which governs it to a certain extent. rllhe type cylinders may vary slightly in size or it may be desirable to use cylinders of distinctly di'erent diameters, due to the many sizes of tickets to be printed. I therefore preferably mount this type-cylinder so that its center of rotation may be varied with respect to its contact drum or bed, as the case may be, this variance necessitating some readjustment of the inkrolls and also a change in the transmission gears. rIhe means by which these various features may be accomplished will be more fully described in the specification which follows. In that specification and in the drawings which form a part of it I shall Specification of Letters Patent.

Serial No. 679,352.

make particular reference to and show and describe a form of device which I have found particularly effective on a ticket press.

Throughout specication and drawings like reference numerals are employed to indicate corresponding parts and in the drawings: IVigure 1 is a side elevation of part of a printing press embodying my invention, and F ig. 2 is a partial rear elevation of Fig. 1.

The frame 1 carries, in eccentric bearings 2, the printing-cylinder 3 which is adapted to receive ink from two ink-rolls 4, 4, for the purpose of printing the strip S, the latter being supported on the drum 5 which is rotatably mounted in the frame 1.

Ink-rolls 4, 4 form part of a regular inking press series embracing distributing rolls 6, 6 and the transfer roll 7. 'Ihe whole are mounted on arms 8, 8 which are pivotally connected to the frame 1 at 9, and operated by the train of gears 10, 11 and 12.

A. rod 13, fast in ears on the arms 8 is adapted to be engaged by the notches of a pair of hooks 14, 14, these hooks being pivotally mounted on the frame l at 15 and being provided with turnbuckles 16 for adjustment and flattened bosses 17 adapted to cooperate with leaf-springs 18 for holding the hooks 14 in desired positions.

The oscillating take-up roll 20, pivoted to the frame 1 at 21, is adapted to transfer the ink to the distributing roll 6 from the feedroll 22, the latter being intermittently rotated within the ink-well 23.

A train of gears 25, 26, serve with the gear 10 to regulate and cont-rol the relative movements of the printing-cylinder 3 and the various ink-rolls. The intermediate gear 25 is an idler, and in order that it may always be adapted for speed transmission in the train 10, 25 and 26 I prefer to mount it loosely on a sliding bearing 27 which is adjustably mounted at 28 upon the frame 1 so as to permit vertical adjustment.

The usual oscillating device for distributing rolls 6, 6 is indicated at 30, but the general driving mechanism has been omitted as not forming part of my invention.

The inkrolls 4-4 are each mounted in eccentric bearings in the arms 8 for suitable adjustment. When therefore it is desired to replace the ink-rolls 4 the hooks 14 are disengaged from the bar 13 and the frame S swung back, thus exposing the inkrolls for ready removal or replacement. rlhis placing or replacement are all accomplished without disturbing the adjustment or if new adjustment is desired renders the same facile and easy.

Various modications may obviously be made in the form and construction of my device all without departingfrom the spirit of the invention if within the limits of the appended claims.

W hat I, therefore, claim and desire to secure by Letters Patent is l. In a printing machine an impression cylinder, a printing cylinder in printing contact therewith, pivoted arms adjustable relative to said printing cylinder and carrying suitable inking mechanism, a rod connecting said arms, a pair of adjustable arms carrying hooks at their ree ends adapted for engagement with said connecting rod, and means for yieldingly holding said hook carrying arms in operative or inoperative position.

2. In a printing machine an impression cylinder, a frame, a print-ing cylinder journaled therein in printing contact with said impression cylinder, arms swung from said frame and carrying suitable inlring mechanism, a transverse rod fast on said arms, a pair of parallel arms, carrying hooks at their free ends adapted for engagement with said rod, and means bearing against the inner ends of said hook carrying arms for Copies of this patent may he obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. CJ

yieldingly holding said arms in desired position. V

3. In a printing machine an impression cylinder, a printing cylinder in printing contact therewith, pivoted arms carrying suitable inlring mechanism eccentrically mounted therein, a transverse rod fast on said ar1ns, a pair of parallel arms, disposed at right angles to said transverse rod and carryingh'ool'rs at their free ends adapted for engagement over said rod, flattened bosses formed on the inner ends of said hook carryingv arms, and springs cooperating with said bosses for yieldingly holding said arms in desired position. f

4. In a printing machine, an impression cylinder, a printing cylinder adapted fory printing contact therewith and adjustable toward and from said impression cylinder,` inking mechanism adjustably supported relative to said printing cylinder, a rod disposed transversely relative to the Supports of said inking inechlanism,'a pair of arms adjustable relative to said transverse rod and adapted for engagement with said rod near each end thereof, said arms having their inner ends formed as attened bosses, and springs yieldingly engaging said bosses to hold said arms in desired position.

In testimony whereof l aflix my signature in presence oi' two witnesses.
