InKINe MECHANISM.-

To all whom it may concern:

Be it knownthat I, JOHN J. HAtL wELL, a citizen of the United States, resldmg at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Inking'Mechanism, fully described and represented in the and the accompanying drawings,forming apart'of the. same.

This invention relates to improvements in inking mechanism for printing machines, and particularly to the mechanism employed for driving the fountain roll of such mechanisms.

It is one object of the present invention to provide a driving mechanism for the fountain roll which shall' comprise fewer parts than constructions heretofore employed for such purpose, which shall be compact,,and which shall give a-smooth motion to the driven roll. It is a, further object of the invention to provide a construction in which the distributer rolls, when employed, and the connections for driving the fountain roll, may be operated from the same shaft.

For a full understanding of the invention, a descri tion of a machine embodying the now be given in connection with the accompanying drawings, in which- Figure 1 is a side elevation of the improved mechanism, shown in connection with a distributer cylinder and the distributer rolls of a rotary press; Fig. 2 is a plan view, partly in section, of the construction shown in Fig. 1, and Fig. 3 is a detail view, with certain parts broken away to show the construction, taken on the line 33 of Fig. 1. a

Referring now to the drawings, which illustrate one embodiment of the invention as used with a rotary machine, the form cylinder of the press is indicated at 1. The form cylinder is inked by the usual form rollers 2 3 which take their ink from a distributing cylinder 4 of any usual or suitable construction. Machines of this type are usually provided with a number of distributing rolls which cooperate with the distributing cylinder 4 to even up the ink. In the particular construction illustrated, there are three of these distributing rolls 5, 6 and 7, which are supported on shafts suitably journaled in the frame of the machine. These rolls seat on, and are rotated by,

' frictional contact with the distributing cylinder, and are preferably given a reciprocating movement longitudinally thereof to more evenly distribute the ink. As illusshafts beyond the rolls are provided with grooved collars 8 into which take studs 9 on crank arms 10, 11 and 12. These crank arms are oscillated by a rock shaft 13 suitably journaled in the frame of the machine, this shaft beingrocked through an arm 14 having a slotted face 15 into which takes a stud 16 fast on a worm wheel 17, the stud-being off center of the wheel. he worm wheel is fast on a shaft 18, and is driven in any suitable manner, as from a gorm 18' on the shaft of distributer cyliner 4. v

Machines embodying the invention will includea-n ink fountain 19, of any suitable or desired construction, in which is mounted to rotate a, fountain roll 20, which is carried on a shaft-2l suitably journaled in the frame of the machine. This fountain roll is intermittently rotated through connections which are preferably actuated from the shaft 18 before referred to, from which the distributer rolls 5, 6 and 7 are operated.

he connections for effecting intermittent rotation may be varied. In the particular construction illustrated, there is provided a ratchet gear 22 fast on a short shaft 23 suitably journaled in the frame of the machine, this shaft 23 being arranged to be coupled to and uncoupled from roll shaft 21 as desired by any suitable coupling, as by split collar 24. Cooperating with the ratchet 22 is a pawl 25 on a pawl-stud 26 fast on a pawl-arm 27, loose on the shaft 23 before referred to. The arm 27 held on the shaft by a collar 28 having holes 29 in which a suitable tool may be inserted to turn the mechanism over by hand. The pawl-arm 27 is actuated to cause the pawl to intermittently turn the ratchet gear through connections from the shaft 18 before referred to, and these connections will, in the best constructions, be such as to positively operate the arm in both directions.

ile the particular construction somewhat varied, as illustrated, the shaft 18 has fast thereon a cam 30. which has a hub 31. The hub 31 has a slotted outer face in which is mounted a stud 32, this stud being vertically adjustable in the slot through a set screw 33. crank arm 34 w Depending from the stud is a may be i 10b is provided at its lower end with a hole 3 5 To avoid lost motion, an improved connection between the end of the crankarm 34 and the pawl 27 is provided. In the construction illustrated, the hole 35 is round and is adapted to receive a ball 36 which carries a stud 37, the crank arm being of sufficient thickness at this point so that the center of the ball shall be within the arm. The stud 37 takes into a suitable recess in arm 27 and thus throws the arm adistance dependin on the position of stud 32 in hub 31, the t row of the arm27 being positive in both directions. This construction is very simple and compact and return springs for the .arm are eliminated. The pawl arm 27 is furthermore, through the connections described, driven directly from the shaft 18' operating the distributer rolls, thus affording a simple construction, and, through the ball connection to arm 34, lost motion is avoided and a smooth running mechanism produced. a

In inking mechanisms of the type described, the ink is taken from the fountain roll and delivered to the distributing cylinder by an oscillating ductor roll 40 which is operated in any suitable manner. In the particular construction illustrated, this duetor is oscillated from the cam 30 before referred to through a cam roll 41 and rock arms a2, l3, on a rock shaft 44: suitably mounted in the frame of the machine. In the construction illustrated, the cam 30 lifts the ductor from the fountain roll against the distributing cylinder. The ductor, in the construction illustrated, is returned to position by a-spring rod construction 45 of JOHN J. HALLIWELL.
