ARTHUR D. SABCRSKY, or LAKEWOOD, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, To

THE ADVANCE MANUFACTURING COMPANY, or DETROIT, MICHIGAN, A CORPORA- TION OF MAINE.

' Application filed December 13, 1913.

To all whom z't may concern Be it known thatI, ARTHUR D. SABoRsKY, a subject of Austria, and resident of Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Inking Devices for Printing Machines, of which I hereby declare'the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an inking mechanism for a printing machine, particularly mechanism adapted to ink type or printing devices mounted on a drum orcylinder or other suitable support. n

One object of the invention is to provide mechanism for supplying ink to the ink distributing member.

Another object of the invention is to provide means for controlling the discharge or flow of the ink from the ink fountain, whereby any desired amount of ink can be supplied to the ink distributing memben,

With these and other objects in view, the invention consists of the parts or combination-of parts hereinafter set forth.

In the drawings, Figure 1 is a side elevation of an inking mechanism, embodying my invention, and part of a printing machine to which the inking mechanism may be applied. J

Fig.2 is a side elevationlooking at the I mechanism'from the other side and showing the manner of adjustably mounting the severalrolls; Fig.3 is a transverse section of the-rolls and fountain; Fig. 4 is a plan view of the inking mechanism; Fig. 5 is a side elevation of the oscillating roll, Fig. 6 is a view partly in section showing the manner of mounting the fountain roll; Fig. 7 is an end view thereof; Fig. 8 is an elevation of the shifting rolls and the driving means I therefor.

In these views A is a printing cylinder, which is adapted to be rotated in any suit able manner, and B, B, are side frames attached at D, D, to the'frame C of a suitable printing press or machine.

In these frames B, B, the several rolls are mounted. E, E indicate a pair of rolls which are preferably formed of'steel and G, G, indicate a pair of rolls which may be formed from some suitable elastic composition.

INKING DEVICE FOR PRINTING-MACHINES.

Specification of Letters Patent. Patented Oct. 22, 1918.

Serial No. 806,460.

These rolls E, E have-polished surfaces and engage the elastic composition rolls G, G, while the latter contact with the cylinder, being suitably spaced apart to distribute the ink evenly thereon. F, F, indicate gears, fixed to the rolls E,'E, respectively. The gears F F together with suitably mounted gears F, F, and F (which is fixed to the cylinder A) form a gear train by means of which the rolls E, E, are rotated.

The steel rolls are preferably of smaller diameter than the composition rolls, and therefore rotate several times to one rota tion of the composition rolls.

The steel roll E first receives the ink and applies it to the composition roll G. The roll G in turn applies the ink to the second steel roll E, which distributes it over the second composition roll G. Theproportions of these rolls relatively to each other can be determined by their action in use. The composition rolls are preferably mounted in adjustable bearings H, and H controlled by the eccentrics I, I, to exert the desired amount of pressure upon the cylinder and steel rolls. I

The steel rolls E, E, are, during operation of I the press, preferably reciprocated or moved longitudially of their axes for a purpose well known to those skilled in the art to which my invention relates. This movement may be elfected by means of rock arms J, J mounted upon a shaft K and a slotted arm K and crank K fixed to a shaft K the opposite ends of which have bearing in supports 70, 7a.' The shaft K is preferably provided with a worm wheel K meshing with a worm K which may be fixed to the shaft K of one of the reciprocating or driven rolls E, E. g

This constant shifting of the positlons of these steel rolls serves to distribute the ink more evenl over the surface of the composition rolls, G.

L indicates a fountain roll which may be formed of any suitable material, such as steel. The roll L is preferably rotated relatively slow by means of the worm L upon the shaft K and a worm wheel L upon the shaft L of the fountain roll.

The roll L receives ink in the form of a film distributed upon its polished surface by means of a blade M, which may be relatively thin and formed of steel. The blade M may be mouht'ed between the side' fi'ames B, B, upon'abar N which is detachabl'y secured in the cross bar N by screws N iSet screws N N arranged at regular intervals: in the "bar N may be rovided to 7 press upon the lower edge of the steel blade M, and adjust with thegreatest nicety the distance of its free edge from the surface of the "rc'iller L. As the blade M isr'el'atively thin, it will spring enough to permit oneportion of its free edge to be brought nearer the roll than another-so that'the thickness of the coati-ngor fihn distributed on the roll L can be regulated either along. the entire roll or part'orparts thereof. a a

o 0 indicates a device for conveying the ink from the fountain roll to. the first one of steel shifting rolls. Thedevice 0 preferably comprises a roll formed from a suitable composition.- The roll 0 is mounted to oscillate or swing freely between the fountain roll L and the adjacent shifting roll E.

I Thisis accomplished byfrnounting the oscil-lating-and conveying-roll 0 upon afram'e O which is pivoted at O? in the sideframes. Two camsOE, Otalter-nately engaging the .pinO upon theframe 0 give alternately forward and rejarwardmovement to the I roll. The ca-ms rotate with the shaft K and the duration of time in which the'roll ism'aking contact with the fountainjroll L and the ad:

- jacentshifting roll Ecan be adjusted byrotating' one of the camsion its axis, and secur- Hl'g it by meansof a set screw 0 Thus theoscillating roll 0 canbeinadeto contact-fora longerperiod of time with one roll than with the other as desired and asthe distributionof ink may require. v

The roll ff) is an idler and hence will revolve rapidlywhen'in contact with the steel roll E and more-slowly when. in contact with the fountain roll L, since its speed willcorrespond with the speed of the roll it makes contact with. I r a Oiindicates a spring, preferably of the coiled -type, having one end-connected to a cross bar O and itsjopposite endconnectedfat 0 to the support 0. The connection O jb (5bWGl1 the spring 0 and the support 0' is preferably arranged on that side of the pivot 0 remote from the bar 0 so that the spring, which is normally active, will tend; ;t-o -swing the support 0' about its pivot in one direction or the other Whenever the support is moved by the cams O 0*, to. bring the connection 0 -to one side of line cutting the axes of the pivot O -'-and bar 0 This construction and operation will be clearly understood from Fig. 3. As the spring 0 serves tofswing the.

support 0 laterally to cause engagement of theroll-Qwi-th either roll E orfL, gafter'the roll Lf-has been'disengaged from the other roll, E or L, the.- roll 0 will alwaysengage these roll-s yi'eldingly. The resilient pressure thus 'obtai'ned coihpels t-oiitaa the consprings flesh provided with a point or device-s, W-hichbearsupon orengages the adj ace'nt plate P, @pre-ferablyEatf or near its center of gravity, to maintain the plate against the adjacent end offthe roll L. -S S, indieatethunib screws which engage the springs S and; serve toaadjust't-he tension thereof against-the plates P.

The springs and gpl-ate's are pre-ferably inclosed in openings betweenthe side-frames and er ds ofthetransver's'ebar.

This method of'f -orming theinking foun;

tain prevents any leakage and drippingof ink and is very easy-to c1eansinee the plates and blade jean readily be taken ut, and; no grinding of, the curved surfaces isneeessary to make the joints tight. The deviee is therefore economical-to manufacture, and
