where the bolts are provided with heads [5 which i rotary printing presses, especially where quick drying inks anddrying apparatuses are employed, it isnecessaryto runthe press a suflicient time to bring the heating. elementsof the dryingapparatus up to the required temperature to quickly and .efilciently dry the impressions. During this heating-up period the ink supplied tothe distribution should-be out ofito prevent overlap thesaid end supports to retain them in the grooves 8, i i l l Themeans for moving the ink transfer roller 4 p intoand out of its operative position may be its loading up with an excessive amount of ink 1 before the actual printing operationstarts.
.The object of my invention istoprovide-novel means for stopping and reestablishing theflow of-ink from the inksupply to thedistr-ibution.
My invention comprises means for moving the ink transfer rollerinto and out of contact with its ink supply and distribution rollers, when desired, without affecting the drive for the ink supply roller or the initial adjustments of the ink transfer roller for parallelism, and while the press is running or at rest. a
A practical embodiment of my invention is represented in the accompanying drawing .in
or fountain roll.
Fig. 1 represents a detail end view partly in section, with theink fountain bowl removed, of
an ink distribution embodying my invention.
Fig. 2 represents a detail end view of the same with the ink transfer roller shown in its operative position in contact with it ink supply and distribution rollers. a l Fig. 3 represents a detail section taken in the plane of the line III-III of Fig. 1,.lo king in the direction of the arrows, with the ink transfer roller shown in its inoperative position out of contact with its ink supply and distribution rollers. i I
Fig. 4 represents a detail cross section taken in the plane of the line IV-IV of Fig. 5 represents a detail section taken in the plane of the line V--V of Fig. 1, looking in the direction of the arrows.
The ink supply or fountain roller is denoted by l and it may be continuously driven, as
through the usual gears 2 and 3, from a suitable drive not shown herein.
The ink transfer roller 4 is located between a continuously driven ink supply Fig, 2, looking in the direction of the arrows constructed and arranged "as follows: A hand operated rock shaft I 6 isjournaledin thesaid frames I2; A handcrank l1, locatedoutside of one of the side frames, isprovided for operating the said rock shaft. Stops [B and 18 on the said side frame serve to limit the throw of the hand crank. Thisrockshaft I8 extends through longitudinally elongated slots 20 in the end supports I for the ink transfer roller land also through.
longitudinally elongated slots 2 I: in the eccentric receiving blocks 22; Eccentrics23 are provided on the rock shaft [8 for operating the end supports. In the present instance these eccentrics engage the opposite upper and lower parallel walls of transverse recesses 24 in the blocks 22. Upper and lower screws 25 and 26 extend through longitudinally elongated slots 21 and 28 in the end supports into threaded engagements with the eccentric receiving blocks 22 for securing them to said end supports. 7
The means which I have shown for initially and independently adjusting the ends of the ink transfer roller 4 both arcuately and radially to bring it into parallelism and proper normal contactjwith the ink supply and distribution rollers I and 5 is as follows: The brackets 9. are provided with pairs of adjusting screws 29 and 30 which engage the opposite sidesofthe bolts l0.
By releasing the nuts ll of said bolts III the screws 29 and 30 may be tumedto individually adjust the brackets, their end supports, and the ink transfer roller 4 arcuately with respect to the said ink, supplyand distribution rollers.
The screws 25 and 26 which secure the eccentric receiving blocks 22 to the end supports are and in normal contact with its adjacent ink distribution roller 5 and the ink supply roller I. The shaft 6 of the ink transfer roller 4 is journaled in end supports or sockets 1 slidable longitudinally along shallow grooves 8 in brackets 9 secured by bolts I0 and their nuts .I I to the side loosened when it is desired to adjust the blocks radially with respect to their end supports. To
.accomplish this radial adjustment of the end supports and thereby. the ink transfer roller, screws 3| are joumaled in lugs 32 projecting from the end supports, said screws being threaded into the eccentric receiving blocks 22.
In operation.-When it is desired to stopthe flow of ink from the ink supply roll to the distribution the handcrank I1 is swung from its stop l8 to its stop 19 on the side frame. This movement will rock the shaft l6 andits eccentrics 23 frames l2. These bolts extend through lateral 5 andthus throw the transfer roller 4 out of contact with its ink supply and distribution rollers. When it is desired to resume the inking of the distribution the hand crank may be returned to its original position, bringing the ink transfer roller into contact with its ink supply and distribution rollers.
It will be seen from the above description that the operation of the throw-off device will not disturb in the slightest degree the initial individual adjustment of the ink transfer roller with respect to its adjoining ink distribution and supply rollers.
It will also be seen that the transfer roller may be thrown into and out of its contact with'the ink supply and distribution rollers whether the press is running-or at rest.
It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but what Iclaimis:
1. In an inking mechanism for rotary printing presses, ink supply, transfer and distribution rollers, side frames, a hand shaft journaled therein, brackets secured to the side frames, end supports for the transfer roller, longitudinally slidable in said brackets and slidablyfulcrumed on said hand shaft, blocks adjustably secured to the end supports and having transverse recesses with parallel upperand lower walls, and eccentrics on the hand shaft engaging the upper and lower walls whereby the end supports and thereby the transfer roller is moved into and out of contact with the supply and distribution rollers by the rockiiig movement of the hand shaft. 1
2. In an inking mechanism for rotary printing presses, ink supply, transfer and distribution rollers, side frames, a hand shaft journaled therein,
brackets secured to the side frames, end supports for the transfer roller, longitudinally slidable in said brackets and slidably fulcrumed on said hand shaft, blocks adjustably secured to the end supports and having transverse recesses with parallel upper and lower walls, eccentrics on the hand shaft engaging the upper and lower walls whereby the end supports and thereby the transfer roller is moved into and out of contact with the supply and distribution rollers by the rocking movement of the hand shaft, means for initially adjusting the position of each of the end supports with respect to its bracket, and means for initially adjusting the position of each of the end supports with respect to its block, for bringing the transfer roller into parallelism with the supply and distribution rollers.
3. In an inking mechanism for rotary printing presses, ink supply, transfer and distribution rollers, side frames, a hand shaft journaled therein, brackets secured to the side frames,.end supports for the transfer roller, longitudinally slidable in said brackets and-slidably fulcrumed on said hand shaft, blocks adjustably secured to the end supports and having transverserecesses with parallel upper and lower walls, eccentrics on the handshaft engaging the upper and lower walls whereby the end supports and thereby the transfer roller is moved into and out of contact with thesupply and distribution rollers by the rocking movement of the hand shaft, means for ers.
