ERNEST JAMES SMITH, 0F CHICAGO, ILLINOIS, ASSIGNOR T0 THE GOSS PRINTING PRESS COMPANY, 0F /CHICAGQ ILLINOIS, A CORPORATION OF ILLINOIS.

INTAGLIO-IRINTING PRESS.

To all whom it may concern:

Be it known that I, ERNEST JAMES SMITH, a subject of the King of England, and a resident of Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Intaglio-Printing Presses, of which the following is a specification, reference being had to the accompanying drawings;

My invention relates to intaglio printing presses and it has for its principal object to provide new and improved means for keeping the printing cylinders in rotation after the remainder of the press has been stopped, whereby the ink may be kept from drying To this end it is one of the objects of my invention to provide such a form and arrangement of the connections between the driving motor for the press and the driven parts that said motor shall be adapted to drive the entire press at the desired operative speed and shall be adapted alternatively to drive the printing cylinders at a comparatively much slower speed while the remainder of the press is permitted to remain at rest. It is another object'of my invention to provide means for moving the impression cylinders yout of contact with the printing cylinders adapted automatically at the same time to throw out' of operation; the high speed connections between the motor and the press, permitting the printing cylinders to be driven alone at a slower speed. It is another object of my invention to improve devices of this Itype in sundry details hereinafter pointed out. The

preferred means by which I have accomplished my several objects are illustrated in the drawings and are hereinafter specifically described. That which I believe to be .new and desire to cover by this application is set forth in the claims.

In the drawings Figure 1 is a side view of a press embodying my improved construction and arrangement; Fig. 2 is a horizontal section through the machine of Fig. 1, being taken substantially on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged detail showing the connections of one of the driving gears with its shaft, as hereinafter described;

Fig. 4 is an enlarged detail, being a sec- Speciication of Letters Patent.

tion taken substantially on line H of Fig. 1; f

Fig. 5 is substantially a vertical section taken on line 5 5 of Fig. 4; and

Fig. 6 is a section taken substantially on line 6-6 of Fig. 2.

Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters,-

15 indicates the main frame of my improved press extending above and below a floor 16 provided for supporting carriages 17-18 w ich are adapted to be pushed along suitable rails extending transversely of the press for supporting in position a plurality of rolls of paper 19. Intaglio printing cylinders 20-21 of any suitable type are revolubly mounted upon the framework 15 at opposite ends thereof. The lower portion of each of the cylinders 20-21 extends down into a suitable container 22 adapted to be' provided with a supply of appropriate ink or water color whereby as the cylinders rotate a supply is taken up by the surfaces of the cylinders. Scrapers 23 are provided as is common in presses of this type for removing from the surfaces ofthe cylinders the surplus ink or other coloring matter taken up thereby. The color receptacles 22 are adjustable up and down relative to the cylinders 20-21 by means of screws 24 upon which the receptacles are mounted, the screws 24 foreach of the receptacles being adapted to be rotated by means of a hand wheel 25 acting upon the screw through the medium of a shaft 26 and bevel gears 27 and 28.

`Impression cylinders 29-30 are slidably mounted in the framework l5 by means of bearing blocks 31 (see Fig. 5). Above each of the bearing blocks 31 is mounted a slideblock 32 which is yieldingly held through the medium of a spring 33 in spaced relation to the block 31, the movement of the block 32 relative to the block 31 being controlled and limited by means of bolts 34. 35 indicates a screw-threaded bolt having a swiveled connection at its lower end with the slide-block 32. A worm gear 36 isv mounted by means of screw-threads upon the bolt 35 a short distance above `the slideblock 32, and a second worm gear 37 is slidably mounted upon the said bolt 35 a short Light finely adj ustable distance above tne worm gear'36, being held versely-extending shaft 41.

gears 36-37 are held in position relative to byka suitable key (not shown) against rotation relative to the bolt 35. `rlhe worm gear 36-meshes with a worm 38 fixedly mounted upon the transversely-extending shaft 39, and the worm gear 37 meshes with` a worm 40 Xedly mounted upon a trans- Both of the the worms 38-40 by reason of engagementwith suitable portions of the framework 15. As will be readily understood, when the gear 36 is rotated through the medi-um of the` shaft 39 and the worm 38, the bolt 35 will be raised or lowered relative t-o the framework 15, the bolt being held against rotation b the worm 40 engaging the .worm gear 37,. On the other hand, when the worm gear 37 is rotated through the medium of the shaft 41 and the worm 40, rthe bolt 35 is likewise moved up or down relative to the framework, the gear 36 in that case being held against rotation by its engagement with the Worm 38. It will be understood that each end of each of the' impression cylinders 29-30 is provided with mechanism of the type just described, the worms 384O being mounted upon opposite ends of the shafts 39-41 which extend from one side ofthe press to the other.

The shafts 39-41 are provided at one side of the press with hand wheels 42-43, respectively, by which the shafts 39-41 may be rotated for moving the bolts 35 up and down as desired. As willbe readily understood, when the bolts 35 of either ofthe impression cylinders 29-30 are moved downward together, the slide-blocks 32 will be moved downward, serving to compress the springs 33, causing such impression cylinder to have the desired pressure upon the adjacent printing cylinder 20 or 21.

' When the bolts 35 are moved upward, the blocks 32 are given an upward movement,

serving first to relieve a part of the tension of the springs 33 and serving later to move the blocks 31 and the impression cylinders 29-30 positively upward out of contact with the printing cylinders.

Means is provided f or rotating the shafts 39 at oppositeends of the press in unison, comprising bevel gears 44 mounted upon said shafts (see Fig. 4) meshing with bevel gears 45 mounted upon a longitudinallyextending shaft y46 which is connected by means of a worm gear 47 (see Fig. 1) and a worm 48 with the driving shaft 49 of a motor 50. The motor 50 is providedr with suitable controller mechanism whereby it may be set into operation in either direction for rotating the shaft 46 asdesired formoving the impression cylinders 294-30 in unison either into or out of operative position.

With the cylinders 20, 21, 29 and 30 being driven in operative position by the means hereinafter described, a web 51 from one of the rolls of paper 19 is fed betweenthe printing cylinder 20 and the impression cylinder 29, thence over suitable steam drying coils 52 of any suitable type, thence between the printing cylinder 21 and the impression cylinder 30, thence over other steam drying coils 53 to a slitting device 54 of any suitable type. rlhe two portions of the web separated by the slitting device 54 are superposed upon each other by means of angle bars 55-56 of any suitable type, whence they are run together over a former 57 by which they are given a longitudinal lfold preparatory to being perfected for delivery by any suitable type of folding device not shown. The slitting device 54, the angle bars 55-56, and the former 57 are sup- -ported in position by a suitable framework 58. The web 51, in the construction shown, is led over and about a considerable number of guide rollers which it is not believed to be necessary to describe or to refer to specifically. Two driven rollers 59-60 are provided supported by the framework 58, driven by suitable gearing from a longitudinallyextending shaft 61 which in turn is driven by bevel gears 62-63 from a vertically-eX- tending shaft 64 driven by means of lbevel gears 65-66 from a shaft 67. The folding device is also preferably driven from the shaft 67.l

The means for driving the press comprises a motor 68 of any suitable type provided with a pinion 69 on the armature shaft 70.

A gear 71 is revolubly mounted upon a shaft l 72, being adapted to be operatively connected with said shaft so as to rotate therewith by means of a suitable clutch mecha-4 nism 73 which is adapted to be thrown. into and out of operation by means of a yoke lever 74 pivotally mounted upon the framework of the press. The shaft 72 is connected b-y means of bevel gears 7 5 7 6 with amain driving shaft 77 of the press. The driving shaft. 77 is connected by meansof lbevel gears 7 8-79 with a transversely-extending shaf-t 80,. and is connected by means of bevel gears 81-82 with a transversely extending shaft 83 at the opposite end of mechanism by which the gear 82 is connect- 125 ed to the shaft 83 is reversed, whereby the gear 82 is adapted to drive the shaft v83 in the opposite direction. The shaft 77 is pro-A vided at one end With'a gear 77a which' meshes with a smaller gear 77b mounted tion in Fig. 1, and the printing cylinder 21 will be vdriven in clockwise direction in said figure, as will be readily understood.

Additional means is provided for driving the printing cylinders 20-21 at a slower speed when the impression cylinders 29-30 have been moved upward out of operative engagement with the printing cylinders 20-21. This rotation of the printing cylinders 20-21 independently of the remainder of the press is provided in order to keep the design -upon the printing cylinder in proper condition for printing, this result being attained by the rotation of such printing cylinders in the color receptacles 22, thus preventing the drying of the color upon the designs. In the construction shown means is provided whereby the operation of moving the impression cylinders out of contact with the printing cylinders acts automatically to shift the drivingmeans from the operative full-speed drivlng of.y the whole press to the slow-speed driving of the printing cylinders 20-21 independently of the remainder of the press and the folding device.

The means by which the slow-speed driving of the printing cylinders is effected comprises a gear 89 mounted upon a short shaft 90, said gear being in mesh with the driving gear 69 of the motor. The shaft 90 is pro- Videdwith a worm 91 which meshes with a worm gear 92 mounted upon a longitudinally-extending shaft 93. The gear 92 is provided with `pawl and ratchet mechanism similar to that shown in Fig. 3 by which the gear is operative for driving the shaft 93 in the direction indicated by the arrow upon the shaft 93 in Fig. 2, but is adapted to permit the said shaft 93 to rotate at a greater speed in the same direction independently of the said gear 92. The shaft 93 in turn is connected by means of spiral gears with the shafts 80-83, said shaft 93 bein provided f with spiral gears 91-95 whic mesh with spiral gears 96-97 mounted upon the shafts 80-83, respectively.

When the motor 68 is driving the entire press through the clutch 73, the shaft 93 will be driven at comparatively high speed in the direction indicated by the arrow thereon in Fig. 2, the pawl and ratchet connection between the shaft 93 and the gear 92 permitting such rotation of the shaft 93 independently of the much slower rotation of the gear 92 in the same direction. When the clutch 73 is thrown out of operation, the connection between the motor and the printin cylinders through the shafts 72 and 77 is roken. The connection between the motor and the printing cylinders is then lnaintained through the gear 89, the shaft 90, the worm 91, the worm gear 92, the shaft 93, and the spiral gears 94, 95, 96 and 97, which drive the shafts 80s-83 in the same ldirection as formerly but at a very much reduced speed. By reason of the pawl and ratchet connection between the shafts 80-83 and the gears 79-82, the Slow-speed rotation of said shafts through the medium of the shafts 90 and 93 does not serve to rotate the shaft 77, whereby the entire press including the folding devices is permitted to remain silent with the exception of the printing cylinders 20 and 21.

The means for throwing the clutch 73 out of operation for transferring from the fullspeed driving of the entire press to the slowspeed driving of the printing rollers alone comprises a lever 98 pivotally mounted upon the framework 15 carrying at one endl a lu or roller 99 overlying an arm 100 carried by the slide-block 31 upon which the impression -cylinder 29 is revolubly mounted. The

opposite end of the lever 98 is pivotally l connected to a link 101, the lower end of which (see Fig. 6) is pivotally connected to one arm of a bell-crank lever 102, the other arm of which is pivotally connected to a link 103 which has pivotal connection with the clutch-shifting lever 74. A spring 104 is interposed between a portion of the framework 15 and a Icollar 105 fixedly mounted upon the link 103, serving to hold the link 103 yieldingly in the position which it occupies when the clutch 73 is in operative position. When the shaft 46, or the hand wheel 43, is rotated for effecting an` upward adjustment of the impression cylinder 29, the arm 100 serves to swing the lever 98, moving the link 101 downward and throwing the link 103 to the left in Fig. 6, serving to move the clutch 73 out of operative position, and serving thus to `effect the slow-speed driving ofthe cylinders means adapted to be operated to lseparate said printing and impression cylinders,v and means operated by the separation of said cylinders for reducing the Speed of said printing cylinder.
