Definitions
- the ink fountain is divided into a number of sections corresponding to the number of colors to be printed simultaneously, and the composition rollers, whereby the ink is con- Veyed from the ink fountain to the printing surface of the press, are correspondingly divided into several sections.
- vibrating rollers namely rollers which move laterally to and fro during the operation of i the press are impractical. Therefore, in order to meet such conditions, it is desirable to provide means whereby the vibrator mechanism of such vibrating rollers can be rendered ineffective at-will.
- vent-ion is to provide simple means whereby the vibrating roller can be readily converted into a non-vibrating roller to adapt the inking mechanism for jobs where several colors are to be printed during one printing operation.
- Figure 1 is a plan view of the vibrator mechanism
- Figure 2 shows a section taken along line 22 of Figure 1;
- FIG. 3 is a sectional VIGW' of the vibrator mechanism 1;
- FIG i is a cross-section through the vi.- brating roller shafttaken along line 4- of Figurel V V i
- the vibrating roller 10 is supported at both ends by means of brackets such as 11, keyedto ashaft 12,,which is pivotallymounted within the machine frame 13,
- One end of the vibrating roller, shaft 14 is formed with a screw portion 15 00- operating with a threaded nut or vbushing 16 rotatablysupported within the bearing 17
- friction to the threaded bushing 16 so that'during the normal operation of the vibrating roller, said bushing will be prevented from rotating, and permit'the screw portion 15 of the shaft 14 to operate to and fro within the bushing, .1 provide a spring operated friction plunger 18 arranged as clearly indicated in v thecam surfaces 20 and 21',tlie-'p'lungeris' pulled outwardly against'theaction-of the compression spring 22.
- the friction plunger .18 be readily moved out of frictional engagement with the bushing 16 by turning the-operating knob- 19 through 180, Now, the-friction between thethreaded portion 15 of the shaft 14 and the threadofthe'bushing 16' will not be overcome by the friction between the bearing. 17 and the bushing 16. Therefore, when the operation of the inking mechanismis continued, the. vibrating roller. 10 will rotate, but it willnot be displaced laterally,
- the collar 23 is shown on' the drawing; as being threaded onto the screw portion 15. It is obvious-,g however, .that a split collar with a plain bore'would; equally wellaccomplish the pu pose-in ie .As indicatedabove,.the friction: between the screw 15 and the thread in the; bushing 16 is greater than that betweenthe latter andthe bearing 17 so that when the plunger 18 is. in its inoperative position, the bushin 16 will freely rotate within its; beari11g 1 and consequently the roller 10; will not move laterally. 'However, when.

- a vibrator roller having a threaded shaft, a threaded bushing cooperating with said shaft, spring actuated means manually operable to apply friction to said bushing whereby said roller is vibrated, and means to hold said roller against vibration.
