INKING MECHANISM.

'To all whomt may concern.'

Be it known that I, BRUCE C. WHITE, a citizen of the United States, residing at New York city, county of New York, and State of New York, have invented certain new and useful Improvements in lnkingl Mechanism, fully described and represented in the following specification and the accompanying drawings, forming a part of the saine.

This invention relates to certain improvements in inking mechanism for printing machines.

lt is one object of the invention to provide a construction of simple design for delivering a supply of ink to each column of the form carried by the form member of a printing couple, the inking supplying devices for each column being independent so that the supply of ink to each column may be varied in accordance withthe matter in each column and thus eiect an even and regularv inking of the form and producing a printed page of even and regular appearance.

It is a further object of the invention to provide a construction whereby the independent ink supplying devices may have the amount of ink delivered thereto regulated or adjusted from a point outside the machine, so that the regulation or adjustment may be effected without interrupting the operation of the machine, and in which preferably the ink .is fed or delivered to the ink supplying devices under such pressure as to secure certainty 'and uniformity in the ink supply.

With these and other objects in view, the

invention consists in certain constructions and improvements, a. detailed description of which will be given in connection with the accompanying drawings, in which- Figurel is a yside elevation, partly broken away, of so much of a printing machine as is necessary for an understanding of the .inventio-n; 4

showing one embodiment of the invention, a detached form member carrying a form Specification of Letters Patent.

a plurality of columns wide being illustrated with the columns in their proper relation to the ink supplying devices;

Fig. 3 is a vertical section on an enlarged scale ofthe ink supply reservoir and one of the ink supplying pumps; and l Figs. 4 and 5 are views on enlarged scales, in. plan and cross section, respectively, of the ink delivery nozzles illustrated in Fig. 2.

Referring now to the drawings, the in-y vention 1s shown as employed in connection tion illustrated is effective for the purpose, y

it will be understood that this train of rolls is not essential to the machine, and lthat any or all of such rolls may be omitted asf-mayv seem necessary or desirable.

there 4is provided a plurality of ink supplying devices by which ink is supplied for the form one such device preferably being provided for each column of the form, and these devices v'being independent of each other so that the ink delivered by each may be varied `independently of the others, and the ink ,is supplied to the form columns or sections under pressure and in-regular quan- A tities by separate pumps so that.thelink is forced to the distributing cylinder or other ink-receiving member with certainty and uniformity. These ink supplyingxdevices may vary somewhat in their construction,

but in machines embodyin the invention in its preferred form these evices will be in the form'of small delivery nozzles 7 suitably .mounted on the frame of the machine and having their delivery orifices arranged side by side and in line, each delivery orifice being, as`shown, the widthv of onecolumn of the form to which ink is to be supplied. These nozzles 7 may be of any suitable construction. As illustrated, the bottom wall of the nozzles is formed of a plate 8 bolted by flanges 9 to a cross frame 1() suitably secured in the machine. This bottom plate 8 is common to` all the nozzles, and is of a length sufficient to provide the necessary number.

The plate 8 is illustrated curving upwardly, as indicated at 11, so as to deliver upwardly between the distributing cylinder 5 and roll 6. The separate nozzles are formed oncommon plate 8 by curved side walls 17 which diverge from the rear sides of the nozzles, and cover plates 18, preferlably separate for access to the different nozzles. The side Walls 17 carry nipples 13 lhaving inlet openings 14 communicating with independent ink supply pipes,and are shown as secured to plate 8 by screws 15 and the cover plates 18 are secured in position to plate 8 by screws 19. As illustrated,

nozzles being connected with the source of' supply through independent connections. .In machines embodying the invention in its preferred form, the ink is delivered from the main source of supply to the delivery nozzles or reservoirs under pressure, this being preferably accomplished by providing a series of pumps, one for each nozzle, and in the best constructions means will be provided whereby the amount of ink delivered by each pump may be varied. In order that this regulating and adjusting means may be` readily accessible, the supply reservoir or fountain is located on the outside of the machine and has mounted therein the pumps by which the ink is supplied. In the construction illustrated, the supply fountain is marked 2O and is located on the outside of the machine, being supported on theframe by brackets 21. From the supply fountain independent conduits, as pipes 22, lead to the deliveryl nozzles. Each delivery nozzle is connected withits pipe in any suitable manner to forni a tight joint, as by forming the end of the pipe 22 with a head 23 which abuts against the nipple 13 before'referred to, connection being made by athreaded union 2.4 taking over the head 23 and screwing onto nipple 13. Located in the main fountain 20 are a plurality of pumps, one pump being provided for each of the pipes 22 which are secured to their respective pumps by means of suitable unions 25.

The particular type and construction of pump employed for delivering ink to the ink pipes may be widely varied, as may be the means for effecting adjustment or regulation of the ink delivered from each pump. A convenient construction, however, is that illustrated, in which the pumps are small vplunger pumps and -are driven through suitable devices from` a common shaft. The construction of each pump is identical, anda description of one will sufce for all. One of these pumps is illustrated in Fig. 3. In' the particular vconstruction there shown, the fountain has Secured therein a casting 26 in which is formed a suction chamber controlled by a ball valve 27 and a delivery controlled by a ball valve 28, one of these being provided for each pump. The pump itself comprises a frame 29 carrying at its lower end a plunger'30, the frame being formed to provide above the plunger an abutment 31. This frame is reciprocated vertically to eect suction and delivery by means of an eccentric disk 32 carried on a driving shaft 33, the eccentric disks for all the pumps being carried on this shaft. The eccentric disk 32 on the rotation of the shaft bears against the abutment 31 and causes the plunger to operate to deliver ink through the valve 28 controlling the delivery chamber. In the particular construction illustrated, the delivery stroke of the plunger is always the same. To provide for regulating the adjustment of the amount of ink delivered by each pump, means are provided for varying the suction stroke of the pump. lVhile the means for effecting this may be somewhat varied, in the construction illustrated there is provided a movable abutment which is in the form of a screw 34 having at its lower end a head 35 and at its upper end a milled head 35 by which the screw may be adjiisted, this milled head being on the outside of the fountain. This screw 34 passes through the upper part of the 'frame 29, before referred to, and the head 35 is engaged by the eccentric disk 32, causing the pump to be lifted for the. suction stroke. It will be seen that by varying the position of head 35 of the screw vertically with respect to the eccentric disk 32, the lift or Suction stroke of the pump will be varied,

and thus the quantity of ink` delivered by the pump at each reciprocation thereof to vary. Furthermore, it will be observed that with the construction employed, the parts through which this adjustment are obtained are conveniently located on the outside of the machine, so that the desired adjustment can be made while the machine is running, and at the same time afford a very simple means for permitting an adjustment to be made quicklv.

The shaft.) 33 of the machine which operates the pumps may be driven in any suitable manner. In the particular construction illustrated, Where a distributing cylinder as 5 is employed, the shaft 33 may be driven from the cylinder shaft and in the best constructions the shaft will be driven through frictional driving means, so that a very-nice degree of adjustment as to the speed of the shaft may be obtained. In the particular construction illustrated, the shaft 36`of the distributing cylinder 5 is provided beyond its journals With a friction disk 37 v With Which coperates a friction Wheel 38 carried on a shaft 39 suitably journaled in hubs 40. This shaft is provided at one end With a Worm 4lvwhich engages With a Worm- Wheel 42 on the end of shaft 33. The friction-Wheel 38,v before referred to, is keyed on the shaft 39 so as to have a movement along the same, whereby it maybe brought into different driving positions With the disk 37 and its speed regulated to a great degree of nicety. rlhe friction-Wheel may be moved along the shaft 39 inany suitable manner. In the construction illustrated, there is provided a nut 43 having yoke arms 44 Which take against hubs 45 on the Wheel 38. This nut is operated by means of a threaded shaft 46 journaled in hubs 47 and turned by means of a hand-Wheel 48. With this construction it- Will be seen that by one adjustment the speed of all the pumps mayA be varied simultaneously, and consequently the quantity of ink delivered by them may be varied likewise. At the same time each pump may be adjusted independently of the gther's to vary the amount of ink delivered y it.

While 'the vconstruction illustrated vand described is one which is effective for carrying out the invention, it Will be understood that changes and variations may be made in the arrangement of the device shown and described and that the invention is not to be limited to such arrangement and construction.
