WILLIAM H. KELLY, OF WESTFIELID, NEW JERSEY, ASSIGNOR T AMERICAN TYPE FOUNDERS COMPANY, OF JERSEY CITY, NEW JERSEY, A CORPORATION" OF NEW JERSEY,

PRINTING PRESS.

- Original application filed August 6, 1,921, Serial No. 490,290, and in Great Britain July 27, 1922.

Divided and this application flletkguly 7, 1925. Serial No. 42,086.

The present invention relates to printing presses and particularl to inking mechanism for bed and cylin er presses.

This application is a division of my application Serial No. 490,290, filed August 6,

One of the objects of this invention is to provide an inking mechanism for presses of this type in which certain of the rolls '10 are driven through transmission mechanism 'A further object in connection with the inking rolls is to provide an adjustable vibrating means so that the throw or extent of vibration of the rolls may be varied independently, one roll vibrating more than another and thus giving a better and more uniform distribution or cutting up of the ink.

A still further object is to provide means forraising the distributing rolls from the form rolls without disturbing the operating connections of the former and to provide convenient means for holding the rolls in either their 0 erative or raised positions.

Referring to t e accompanying drawings:

Figure 1 is a side elevation of a fragment of the press fully shown in my application referred to above, this view showlng only those parts of the press directly associated with the inking mechanism;

Figure 2 is a side elevation of the opposite side of the press, this v1ew also omitting all-elements of. the press except those necessary to illustrate the inking mechanism;

Figure 3 is a vertical longitudinal section through the press, showing more particularly the inking rolls and the train of gearing for operating the rolls;

Figure '4 is a diagrammatic view illustrating the mechanism for reciprocating the bed and actuating the inking rolls;

Figure 5 is a side elevation of the pivoted inking roll frame; and

Figure 6 is a partial plan view, parts being in section, illustrating means for vibrating the ink rolls.

The inking mechanism may be of any suitable form, but according to the resent invention, some of the rolls, prefera ly the vibrator rolls, are driven from the bed reciprocating mechanism. As shown in Fig- 'ures 1 and 2, the form rolls 92 are carried in suitable adjustable bearings 93. The upper rolls 96 and 98 and the vibrator rolls 97 are carried in bearings on .a pivoted frame 94 pivoted on a shaft 95. A roll 96 rests on the vibrator rolls 97, and aroll 98 rests on one of the vibrator rolls 97 and a large pipe roll 99, this latter roll being concentric with the pivots of the frame 94. Ink is transferred from the fountain roll 100 to the roll 99 bya ductor roll 101, the fountain 102 being of any suitable construction. The side members of the frame 94 at their free ends rest on lugs 103 carried by the cylinder housings of the press, and the frame is locked down against elevating movement by the arms 104 carried by a shaft 105 secured to the cylinder housings. One end of this shaft is provided with a knob 106 at one side of the press so that when this knob is rotated both arms 104 will be swung upwardly. Thereafter by depressing the handle 107, the ink roll frame 94 may be elevated to the position 108 indicated by the dotted lines in Figures 1 and 2. To, hold the ink frame in this elevated position, the arms 104 may be swung under the tip ends of the side members of the frame, assuming the position indicated by the dotted lines 109.

tween the segmental gear t9 and the side 10c frame 36, this cam acting on a bell crank lever 119 (see Figure 2) connected by link 120 to the arm 121. A spring 122 holds the bell crank in contact with its cam 118.

Referring to Figures 3 and 4, the train of gears for rotating the vibrator rolls 97 is driven from the gear 54: on shaft 53, said gear meshing with the bed rack and thereby actuating the bed. Gear 54 also drives a gear on shaft 124. and gear 125 on this shaft meshes with gear 126 which in turn drives gear 127, then gear 128, the train being completed by the gears 129, 130, 131 and 132. (See Figure 4). In this. manner the vibrator rolls 97 are positively connected with the bed driving gear and their rotations are therefore timed with the reciprocation of the bed. so that even if the vibrator rolls are axial movement, thus reducing the extent of vibration of the rolls 97. Hence the vibration of the rolls may be adjusted and independently, that is to say, the extent of vibration of one roll ma be different from that of the other, thus istributing and cutting up the ink better. This adjustment of the extent of vibration is of great utility in connection with the employment of differentl colored inks. Furthermore, the particu ar form of vibrating means used assures the return of the rolls to their exact former positions after the frame 94 has been raised. Hence the vibrating means in conjunction with the means for rotating the rolls provides for the rotation and vibration of the rolls in exact timed relation with the cycle of movements of the press.

Having1 thus described the invention, what is claime as new and desired to be secured by Letters Patent is:
