VIBRATING ROLLER.

Application filed September My invention relates to rollers suitable for use in printing presses and refers particularly to vibrating inlring rollers for such described use.

In roller printing presses it is essential that the ink be distributed evenly over the inking roller and to accomplish this purpose it is usual to have a plurality of inlring rollers rotatable by their movement over the inking plate, combined with which is a roller revoluble by its abutment upon the inking rollers and having a transversey movement along the faces of the inlring rollers in order to more evenly distribute the ink thereon.

Such rollers are known as the vibrating rollers.

Among the desirable features which should be possessed by vibrating rollers are the following They should revolve continuously with the revolution of the inking rollers, they should have a reciprocating movement along the faces of the inling rollers, they should be prevented from side slips along the `faces of the inlring rollers, they should be easily removed from contact with the inking rollers when desired for cleaning or repairing pur,n poses and be capable of retention in such noncontact position, they should be easilyv removed from and inserted into the press mechanism, they should be positive in action.

The device of my invention possesses all of the above mentioned and other desirable properties as will be evidenced from a consideration of my specification and its accompanying drawings. v

In the accompanying drawings illustrating modified forms of the device of my invention, similar parts are designated by similar numerals.

Figure 9 is a top view of a modified form of housing.

Figure 10 is a cross-section through the line 10 10 of Figure 9.

The particular form of the device of my invention shown in the accompanying drawings comprises a hollow roller 10, through which passes a tubular shaft 11, supported by the bearing 12 and reduced end portion 13 of the roller 10. Revoluble upon and slidable upon the shaft 11 is an externally threaded hollow spindle 14.v The interior end 15 of the spindle 14 is angularly faced or `cam edged. Transversely movable upon the shaft 11 is a cam, or clutch, member 16, one end face of which is angularly abuttable upon the'end 15 of the spindle 14. The cam member 16 has a plurality of slots 17, 17.k A coiled spring l19 is maintained under tension between the clutch 16 carried by the hollow shaft 11 and the pin 20 carried by the shaft 11. The interior thread of the end liange 13 of the roller 10 meshes with the threaded spindle 14.

If the shaft 11 be retained from revolution, and the roller 10 be revolved, the spindle 14 will be maintained in non-revoluble position upon the shaft 11 and the meshment member L 13 with the threads of the spindle 14 will cause the roller 10 to have a transverse movement along the shaft 11. When the pin 21 of the member 13 reaches and abuts 4upon the stop-pin 21 and the revolution of the roller 10 around the spindle 14 is prevented, the spindle 14 and the roller 10 will revolve together around the shaft 11 because of the engagement of the pin 21 with the pin 21 car ried by the end member 13. Similarly, when the pin 21 of the member 13 reaches and abuts upon the pin 22, the spindle 14 and the roller 10 will revolve together upon the shaft 11. It will thus be seen thatthe tension of the spring 19 and theabutment of the two cam,

or inclined faces, of the members 15 and 16 maintain the spindle 14 from revolution while the roller'lO is capable` of revolution around the spindle during'its transverse movement,

but when this 'transversemovement is pre-Y vented, the roller '10 and the spindle 14 re- Ivolve together. This is a most important attribute of a device ofthischaracter as it in sures the constant revolution of the roller during its use.

4Within oneend of the shaft 11 and flXedly attached thereto by the pins 23, 23 is an eccentrically positioned end support 24 having a longitudinally positioned slot 25. The suptended gripping member 37 and 38. The

port 24 has the stop-pin 26 and the operating member 27, both integral with the support 24.

Vithin the other end of the shaft 11 and fiXedly attached thereto by the pins 28, 28 is an eccentrically positioned end support 30 having the stop-member 31 integral therewith.

The support for the end support 24 comprises a U-shaped housing 32 having the integral outwardly extended base members 33, 33, the rearwardupper .face 34 of each base member being inclined downwardly and the forward portion of each base member having a downwardly extended clamping flange 35.

A. clamping member comprises two U- shaped members 36, 36 each having the eX- two U-shaped members are connected by the integral rib 39, and the gripping members 38, 38 are connected by the integral flange 40. There is thus formed a clamping member having two upper spaced gripping members and two lower gripping members. Each upper gripping member 37 has a rearwardly inclined threaded hole 41, within which is a threaded set-screw 42 having an angular opening 43 longitudinally therein.

Pivotally carried within the housing 32 of the end support 24 at 44 is a locking member 45 having the key 46 and the thumb piece 47. The key 46 is held in normal position by the spring 48.

To attach the housing'to the roller supporting bracket 49 of a printing machine. the housing 32 is placed upon the upper face of the bracket 49, the clamping anges 35. 35

extending over the side face thereof. The clamping member is then placed upon the opposite side of the bracket 49 with the gripping members 37, 37 extended over the base 34, 34 and the gripping members 38, 38, resting against the under face of the bracket 49.

An angular tool is then placed in the holes 43, 43 of the set screws 42. 42 and the setscrews screwed inwardly, the interior ends of the set-screws being inserted in the in,- clined recesses 50, 50 of the base members 34, 34. The inclined movement of the setscrews 42, 42 draws the clamping flanges 35, 35 into contact with the inward face of the bracket 49 and the gripping members 38. 38 into contact with the lower face of the bracket 49, the one movement of the set-screws thus causing a firm gripping and connecting means between vthe housing and the bracket.

The housing of theend support 30 is similar to that above described except that the locking means does not have the key 46, and the lower face of the locking means has an inclined recess 51. y In Figures 5 and 6 the full lines represent the device in disengaged position and the dot-and-dash lines represent it inengaged position.

The method of placing the described vibrator roller into the printing press is as follows The housings are clamped to thev brackets as above described. Lift the left hand locking means by means of its thumb piecev47 and slide the end 30 thereunder as far as it will go, the stop member 31 passing thereunder through .the recess 51. Then raise the right hand'locking means by means of its thumb piece 47 and pass the end 24 thereunder, allowing the key 46 to fit within the slot 24. The device is then the position shown in Figures 2 and 3. It will then be noted that because of the eccentrically positioned ends 24 and 30, the vibrating roller 10 is in raised position and hence out of contact with the inking rollers 53, 53.

To place the vibrating relier 10 in operating position, that is in contact with the inking rollers 53, 53, it is revolved 180o by lifting key 46 from rvslot 25. It is removed by disengaging roller first, then lifting thumbv piece 47 at end 30, drawing 30 under the cam roller out to the right.

It will be noted that the device is held free from transverse movement in both operative and inoperative positions.

the shaft 11 from transverse and rotational movement.

It will be noted from the above that the cam movement of the spindle 14 operates to insure a constant revolution of the vibrating roller even when it abuts upon the side of the Y. y device and is prevented from further transverse movement.

It will be further noted that the vibrating roller of my invention is readily placed in an is free from side-slip and that it can be easily removed from and inserted within the printing press.
