INKING MECHANISM FOR PRINTING-MACHINES.

To all whom it may concern:

Be it known that I, BRUCE C. WHITE, a citizen of the United States, resi'din at .New York, county of New York, and tate of New York, have invented certain new and useful Improvements in Inking Mechanism for Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to an improved inking mechanism for printing machines of that type in which the ink is forced by pumps to, the distributing cylinder or other portion of the inking apparatus so as to supply the ink under pressure and in regulated quantity and preferably so that the supply of ink to each column or other section of the form may be varied as desired in accordance with the matter to be printed.

The special object of the invention isto provide a more efiicient and. satisfactory apparatus for thus supplying the ink and regulating the supply from a convenient point and without interrupting the operation of the machine, and to secure greater certainty and uniformity in the supply and distribution of the ink.

With these objects in view, the invention includes various nov,el. features, constructions and combinations of. parts in inking mechanism, and a novel pump designed especially for such use, but applicable also to other use and for pumping other fluids.

For a full understanding of the invention, a detailed description of an inking mechanism embodying the invention in its preferred form, and a modified form of pump, will now be given in connection with the accompanying drawi" s forming a part of this specification, and t e features forming the invention then specifically pointed out in the drawings.

Referring now to the drawings, the invention is shown in Fig. 1 as applied in connection with a five web press having rotary printing couples, each couple consisting 0 the form cylinder A and impression cylinder B, the form cylinder A taking the ink from form rollers a supplied from distributing cylinder C having the usual vibrating ink distributing rolls 0. This is a common type of such printin machines, but it will be understood that .t is is shown only for purpose of illustration and that the invention is equally applicable to other types ofprinting machines, either reciproeating or rotary, and with any desired type culating pipe I, through which ink is con tinuously circulated from tank G by any I suitable means, as, for instance, by the rotary pump K, indicated in F ig. 1, so that the supply of inkin reservoirs: F is constantly .maintained under-control of a float valve, as-

hereafter described, the branch pipes H- for the separate supply reservoirs F preferably being provided with cocks, as shown, soas to cut out of the inking system any supply reservoirs desired when their printing couplesv supply reservo1rs,'conduits or suppl pipes E and nozzle casings D, are shown in'Figs. 4 v

I to 3, the whole inking apparatus occupying but a small space at the side of thedistributing cylinders, so as not to substantially interfere with the desired access to the press,

v and the supply reservoirs being conveniently ing plunger 10, is provided for each desire placed for access and adjustment of the ink supply, without interfering with the operation of the machine.

The construction and operation of the ink pumping and regulating apparatus within the supply reservoirs F,'and of the nozzles for delivering the ink to the distributing cylinders, are duplicates, each of these being as follows: The interior of the supply reservoir F is partially filled with ink, in which work the ink pumps by which the ink is forced downward through the conduits or supply pipes E, which are ings formed in the bottom of the reservoir. A single acting pump, having vertically actsection of the form, usually a column, two parallel rowsv of these pumps being shown,

the pump chambers for these pumps being formed in bars 11 extending lengthwise of the'reservoir .F and united by cross bars 12 to form a frame open betweenthe bars 11 to receive shaft 13 carrying eccentric 14, by which the frame, With its pump cylinders and plungers, is moved sidewise and the plungers 10 reciprocated, the eccentric 14 securing this sidewise movement of the frame" through action on yokes on cross bars 12 of the moving frame, and the vertical movement through action on vertical bars 15 mounted'to slide vertically in these yokes whileheld from sidewise movement therein. These bars 15 form downward extensions of a bar 16 extendinglongitudinally of the reservoir above the pumps and which has arms 17 extending over the pump plungers 10 so as to engage and operate the latter on the downward movement of the plate bar 16. This bar '16 also carries arms 18 extending on opposite sides of-the bar, which arms carry pivot shaft 19 on which are loosely mounted rock arms 20, one for each plunger, having toes 21 extending inward under packed in openflangedheads 1 of plunge rs 10, and these arms 20are formed of a sleeve'and inclosed sliding stem, so as to be extensible and spring-pressed apart by spring 22, the sleeve having a head 23 numbered to correspond with the column or section of the form supplied by its pump, and the sleeve being provided with a catch 2 adapted to engage teeth 3 for holding therock arm in adjusted position, these teeth 3 being formed in the underside of arms 24 projecting in opposite directions from central web 25 extendin upward i from bar 16, the arms 24 prefera ly being made separately and secured in slots in the web 25 by a coverbar 26,-as shown. The ends of the arms 24. are tied together by rods 27 with spacing sleeves between the arms so as to form the parts carried by bar 16 into a frame that reciprocates vertically in the frame formed by bars 11 and cross bars 12 and moves sidewise with the latter frame. I

' The shaft 13 maybe driven by any suit-' able means, but as shown is driven by gear 28 and intermediate 29 from gear 30 on sleeve 31l'oose' ondriving shaft 32 and carrying disk '33 having handle 34 mounted therein, thisv handle 34 having a point 35 entering a recess in disk 36 keyedto shaft 3 2, so as to clutch disk 33 and sleeve 31 to the shaft for driving the pumps when the handle 34 is thrown into the position shown in Fig. 7, while by rocking handle 34 outward against its holding spr ng into the position shown in Fig. 4, sleeve 31 is released from shaft'32, .and the pumps can then be run by hand at the ,speed desired for testing,

runthrough the umps and pipes, if desired. The driving $113,1 0 32. maybe driven from the dcleaning or repair, or cleaning fluid may be.

press by any suitable gearing so as to'secure the proper speed, or may be driven by separate motor, if preferred.

The ink is 'preferablymaintained at the desired level in the reservoir F by float control, the inlet pipe H .being controlled by valve 36 under the control of float lever 37 and float 38, which parts may-be of any suitable construction. Circulation of ink from the side of the pump frame at which supply pipe H enters isfprovided for by passages 39 connecting side troughs 40 with a central trough 41, with which connects a drain pipe 42, provision thus being made for draining the reservoir from troughs 40, 41, in which any sediment orthickened ink will collect and for washing the reservoir by running water or cleaning fluid theredistributing cylinder or other part of the P .the outer wall of The conduits or supply pipes E from thereservoir F have their delivery ends arranged in line along the distributing cylinder C, being grouped in casing D, as shown in; Figs. 8 and-10, this casing D being provided with a removable cover 44 for access to the pipes, and the wall '45 of the casing adjacent to the distributing cylinder havinv openings therethrough receiving the ends of the-pipes and through which the ink passes to the nozzles supplying the distributing cylinder.

In the" construction shown in Figs. 8 to 10, these nozzles deliver through the ports in support plate 4.5 into narrow passages .46 outside plate 45, by which the ink is distributed sidewise from the pipes to substantially the extent of a column or other section to be supplied with ink by the pipe, 20

and these passages have small dellvery orifices 4, of unobstructed circular or other polygonal form, a sufficient number of which are formed on each passage to secure the distribution required, and the ink from these openings falls down the inclined face 5 of abar or nozzle piece47mounted on: the

outer side of plate 45 and acting to form passages 46, previously described, and to divide these passages from each other. a

The inclined surface 5 extends substantially into contact withthe distributing cylinder 0, and the ink from the orifices 4 spreads in flowing down the incline so as to form a continuous thin layer or film of ink in contact with the distributing cylinder. The small orifices or passages 4, through which the ink is distributed from passages 46, preferably extend upward, as shown, soas to assure their being constantly filled with ink and prevent the entrance of air from outside, as might be the case if they were directed downward from found in practice secures a better distnibupassages 46'. In Fig. 11 there is shown a modified construction, especially adapted for the heavy ink used in work, in which t e ink is blown by an air onto the distributing cylinder, which it is tion of such ink. The air current or air blast, is shown as provided by an air blast pipe 48 mounted on top of the casing cover 44 and having a suitable contracting. nozzle 6 delivering a continuous air jet, or series of jets, just behind the orifices 4. With this construction, also, the incline 5 is preferably used and acts, as in Figs. 8 and 9, to distribute sidewise, from orifices 4, any ink not forced by the air blasts onto the distributing cylinde r. j The casing D is preferably adjustable towardand fromthe'distributing cylinder C, so as to secure the best positionfor theremalgazine, book and simlilar...

ceipt of the ink from the nozzles by distributing cylinder C, and for this purpose, is shown as carried by bolts 49 securedto the press frame and having adjusting nuts 50, between which arms 51, carrying the casing, are mounted on the bolts. Preferably, springs 52 are used outside the arms-51,

reservoirs F kept full to the required level by the float control of branch pipes H, so

that a constant suction supply to the pumps is thus maintained. The pump chambers formed in-blocks 11 and inwhich the pump plungers 10 move are brought by'ieccentric 14 alternately into connection with the reservoir onthe upward or suction strokerof the plungers 10 and into line with the ports in the reservolir bottom connecting with pipes E for the downward or delivery stroke .of they plungers, and the vertical movement of the bar 16 and lunger operating parts carried thereby 1s secured in proper time by the eccentric 14. A measured quantity of ink is thus delivered by each pump under fixed pressureat each stroke of the plungers 10. These valveless pumps aid materially in assuring the proper action of the pumps and their delivery of a fixed quantity of ink, and avoid the difficulties incident to handling ink with valved pumps. As described above, the lift of each plunger 10 on the suction stroke is determlned by the position of its rocking arm 20 which determines the time of engagement of toe 21 with plunger head 1, and the position of the arms 20 is readily adjusted by moving the numbered heads or finger pieces 23 sidewise. The arrangement of the adjusting heads so that they move sidewise in adjusting the ink supply to the different through-pipe I by pump K and the supply a columns or sections, is such that the rela-,

or sections-"is readily seen, andby arranging the heads so that they are normally in line for equal adjustment of ink for the different columns or sections, a glance at the top of the inking mechanism on raising the cover 43 shows the relative inking of all parts of the page or pages supplied by the reservoir. This. is clear from Fig. 4, in which the reservoir is illustrated as supplying four pages of eight columns each with the inking, mechanism adjusted for equal supply to all columns on two pages, and adjusted for varying the supply to different .modified construction of pumps and regulating means, the other parts of the apparatus being the same as above described.

In this case the plungers 10 and the blocks 11. containing the pump chambers -of the two sets are actuated by separate eccentrics,

I the two blocks 11 being connected by cross plates 54 at opposite ends, which are vertically slotted to receive sliding blocks 55 carrying .eccentric sleeves 56 in which run eccentrics 57 on shafts .58, so that the rotation of-the eccentrics moves the blocks 55,

with the. frame formed by plates 54andbars 11, sidewise, and moves the blocks 55, with 'their eccentric sleeves 56, vertically. The

pump plungei's 10 carry yokes 59, the upper ends of whichare threaded onadjustlng screws 60 having finger pieces 61 extending upward into convenient position for access.

when the cover is lifted and preferably held in. any-adjusted position by springs 62engaging the knurled side of the. finger pieces. The adjustingscrews 60 carry heads 63 engaging the' eccentric rings 56 to raise the plungers 10 the'length of the suction stroke or lift'of the'plungers, the amount Of 'lIlk delivered thus being regulated by the position of the screws 60, which determines'the shown as geared together by gears 64 op-' lift of the yok'es 59 and plungers 10 by the eccentrics. The eccentric shafts 58 may be rotated by any suitable -.means, but are .erated by gear 65 on shaft 66, which in turn is driven through bevel gears 67 from driving. shaft 68 outside the reservoir F, and actuated-from'the press or otherwise in any suitable manner; v In this construction there is shown, also, a convenient-means for cutting out a whole page of the inkinggor such part thereof as the construction may be designed for,"by a single valve, which arrangement also is readily applicable to the construction shown in Figs. 1 to 11, and above described; -For this ,purpose each row of the conduits or supply pipes E connects with a circular valve chamber in which. is lounted arotating valve 69 extending over the whole row of conduits E, or such part thereof as desired, and accessible from outside the reservoir for rotation, as by the squared head 70, shown in Fig. 13. These valves 69 have transverse ports7, and the bottom plate of the reservoir F is prbvided with two passages 8, 9, one connected withthe pump chamber and the other with the reservoir,

so' that by turning ajvalve 69 into the position shown in Figs. 14 and 15, the pumps in the row -corresponding'to the valve will deliver ink from the chamber through ports 8, 7, into the conduits or "supply pipes E, and by turning the valve into the position shown in Fig. 16, the pumps of'its row will be closed to pipes E, and the ink be circulated through ports 8, 7 9, from the pump to the reservoir on the discharge stroke.

The simple rotation of a valve 69, therefore, will cut outa page, or such portion of the inking as the apparatus maybe designed'for, without interferi g with the adjustment of the separate pu'mps. 1

- The operation of the'constructlon shown in Figs. 12 to'16 will be substantially the same as that described in connection with Figs 1. to 11, exceptas will be understood. from the drawings, so that no further de- I scription of operation is required.

a While the construction illustrated and described is one which is effective for carrying' out the invention, and preferably used with presses of the type shown,'it will be understood that changes may be made in the construction and arrangement of the I machines, the combination with a plurality of separate ink conduits, one for each column or section of the form, and an ink ump for each conduit :ofmeans for regu ating the ink supply delivered by each-pump 'independently of the'otli'ers, said regulating means including an adJuSting member for each pump movable sidewise for regulating the ink supply. v I
