To alli/whom t may concernf tained, the ink always being worked in one.

direction and the form rollers `always being in contact with the vibrators during both the printing and return strokes of the bed for insuring a thorough distribution of the ink on the 'form rollers, means being provided for raising and lowering the inking mechanism bodily without interfering`- Y with the connection between the several parts. In the accompanying drawings, Figure 1 represents 1n side elevation so much of a bed and cylinder printing press as will give' a clear understanding of the invention. Fig. 42 is a detail view showingthe means for vibrating the ink cylinder and vibrator rolls, Fig. 3 is a detail longitudinal vertical section through the inking mechanism and its raising and lowering means, Fig. 4 is a detail transverse vertical section showing the'mean's for raising and lowering the ink` ling mechanism, and Fig. 5 is a detail section showing certain of the geared connections.

` `The sheet delivery mechanism and the mechanism for reciprocating the form bed are not shown herein as they form no part of the present invention and will not assist in a clear understanding thereof.

The reciprocatimg bed is denoted by 1 and the` form thereon by 2; theimpression cylinder l"by 3, the fountain roller by 4, the ductor roller by 5, the ink cylinder by 6,- the distributing and carrying rollers by 7, 8, 9, 10, 11, 12; the vibrators by 13',` 14, and the form rollers by 15, 16, 17, 18.

The main drive shaft is indicated-at. 19, which shaft drives the cam shaftl26. through the gears 20, 21, 22, 23, 24, 25. The cams for controlling the movements ofthe foun-A tain roller 4 and the ductorroller-,51,2are'dejjj noted by 27, 28 respectively, and their shaft Vby 29, which shaft is driven from the cam shaft 26 through the train of gears 25,- 30, 31, 32, es, 34.

, The impressioncylinder 3 is driven from the drive shaft 19, through the gears 20, 21,v 35, 36. The' ink cylinder 6 is driven from the impression cylinder gear 36, through the gears 38, 39, 40, 41, and the vibrators 13, 14, are driven from the ink cylinder gear 41, through the gears 42, 43' and 44, 45

, respectively.

The vibrator rolls 13, 14, and the ink cylinder '.6 may be vibrated by any desired means, such, for instance, as that shown in the accompanying drawings, in which the shaft 6* of the ink cylinder 6 is reciprocated longitudinally by the worm 46 and worm wheel 47. The shafts 13* and 14* of the vibrator rolls 13, 14, are reciprocated longitudinally by the rock levers 48, 49,

from the ink cylinder shaft 6*.

l'llhe di'erent parts of the inking mechanism are supported in a supplemental frame 50 hinged at 51 to the main frame to swing vertically to move the form rollers 15, 16, 17 18, into and out of engagement with the form 2. The means which 1 employ for raising the frame during the return stroke of the bed comprises a cam 52`lixed to the shaft 26, which cam engages aroller 53 on an arm 54 of a rock lever pivoted at 55, `said lever having' preferablytwo arms 56 connected to the free .end of the supplemental frame 50, by vertically arranged rods 57. This cam 52 on the shaft 26 is so timed that the supplemental frame 50 will be lowered to bring its form rollers into contact with the form 2v during the forward printing stroke of the bed and, will be raised tocause the'form rollers to Aclear the form during the return stroke of the bed.

It will be seen by the above construction I nee plishing the results herein stated; hence I do not wish to limit myself to the construction herein set forth, but

What I claim is:

1. In a machine of the character described, a main frame, a supplementalframe hinged thereto, a reciprocating bed and its form carried bythe main frame, an inking mech' anism for the form carried by the supplemental frame, and rotary means having an uninterrupted driving` connection with the inking mechanism arranged to automatically raise and 'lower the supplemental frame for bringing the inking mechanism out of and into contact with the form.

2. In a machine of the character described, a main frame, a supplemental frame hinged thereto, a reciprocating bed and its form carried by the main frame, an inking mech'- anism carried by the supplemental frame including an ink cylinder, a pair of` vibrators driven continuously in one direction therefrom and a pair of form rollers driven continuously by each vibrator and rotary means having an uninterrupted driving connection with thel inking mechanism arranged to automatically raise and lower the supplemental frame for bringing the form rollers out of and into contact with the form.

3. In a machine of the character described,

a main frame, a supplemental frame hinged thereto, a reciprocating bed and its form carried by themain frame, an inking mechanism carried by the supplemental frame including an ink fountain, its roller, a ductor roller, an in-k cylinder, distributing rollers, carrying rollers, vibrators, and form HOWARD M.
