INKING MECHANISM.

Specification of Letters Patent.

Patented Dec. 2st, 1918.

7 Application filed January 28, 1916. c Serial No. 74,984.

To all whom it may concern I Beit known that I, ERNEST :J. SMITH, a subject of the King of England, residing 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 following specification and the accompanying drawings, forming a part of the same.

This invention relates to certain improve ments in inking mechanism for printing machines. 1

It is the especial object of the invention to provide an improved mechanism particularly for high speed rota'ry printing machines in which the construction shall' be simple as compared with previous mechanisms, and in'which the parts are easily accessible and so constructed as to facilitate the adjustment of the ink supply, which is particularly desirable in such machines, especially where the inking mechanism is used with an extra couple for printing late news, which is often placed in more or less inaccessible positions in the machine.

With these and other objects in view, the

invention consists in certainnovel parts and combinations which will be described in connection with the accompanying drawings,

to afford a full understanding of the invention. The figure is a sideelevation of one side of the machine illustrating the improved inking mechanism. j

Referring now'to this drawing, the inking mechanism is shown in connection with a rotary press, the form cylinder of which is indicated by the numeral 1, the remainder of the press not being illustrated, as such illustration is not necessary for an understanding of the invention. Cooperating with the form cylinder 1 is the usual form roll 2. In machines embodying the invention in its best form, this form roll 2 is supported so that its pressure on the form cvlinder may be varied within desired limits. While the means for thus supporting this roll may be somewhat varied, in the particular construction illustrated this form roll 2 is supported in suitable bearings in frames 3. only one of which is shown, these frames being pivotally mounted at 4 in brackets 5 rigidly secured to the main frame 6 of the any suitable manner, as by means of set screws 7, 8 provided with lock nuts 9, 10, these set screws being fitted in the fixed brackets 5 and disposed at right angles to each other so as to afford an up and down adjustment of the pivoted frames 3, the screw 7- takjing against the bottomof the frame for affording a vertical adjustment, and thescrew 8 takingagainst a shoulder .11 formed in the end of the frame and holding the frame rigidly in adjusted position. The form roll 2 is a driven roll, being driven in; any suitable-manner, as from the igrrpscylinder through intermediate gearing a 1 The form roll 2 takes ink from-the ink supply and delivers-it:to the form cylinder 1. In machines embodying the invention in its best form, means are provided whereby the ink may be delivered from the fountain or other source of ink supply to, the form roll without the employment of the. usual lifter roll, thus simplifying the construc tion. VVhile-these means may vary somewhat in construction, in the particular construction illustrated .this is. effected by means of an ink fountain 14 provided with a fountain roll 15 mounted in the fountain so as to be normally in'close proximity to but'not in contact with the form roll 2. This ink fountain is furthermore mounted so that it maybe given an intermittent movement to bring the fountain rollinto contact with the form-roll so as to supply an intermittent amount of ink thereto. While this movement and the means for effecting it may be somewhat varied. in the particular construction illustrated this movement is a rocking or oscillating movement, the foun tain 1% being pivotally supported on studs 16 on the pivoted frames 3, before referred to, and is normally held so that the fountain roll 15 is just clear of the form roll 2, this being accomplished in any suitable manner, as by the spring 17. The rocking or oscillating movement is effected in any suitable manner. In the particular construction illustrated. the shaft of the fountain roll 15 is provided with a cam disk 18, which preferably is provided with two lifting cam portions 19. so that the fountain will be rocked and the fountain roll be brought into contact with the form roll twice every time the fountain roller makes a complete revolution. The cams 19 cooperate with a suitable cam surface for effecting the rockingof the.

fountain which, in theparticular construction shown, is a fixed bowl. mounted. in an extension 21 of the pivoted frame 3, before referred to. In the best constructions.

this fixed bowl 20 is adjustable to effect an easy and quick adjustment in the amount of rocking movement given to the fountain.

While this may be accomplishedin various ways, as illustrated the bowl 520 is eccentri cally mounted inarms 22- s'upported'on the extension- 21 before; referred to. By simplyloosening the securing nuts 20'and"partly rotatingthe-bowl; more or less-of a/rocking movement may easil'ybe given the fountain,

and the extent of;movement or depressionofthe fountain roll correspondingly easily adjusted: r I

The fountain roll-is driven in any-suit able; manner, as by means of the bevelgears' 23' driven from a shaft'Q i, inturn drlventhrough-wormgear 25 from theshaft 26-of the; form roller 2', before referred to;

Machines embodying the invention will also be provided with two distributing rollers- 27, which preferably will beef metal,

mounted in s1ots'28 vformed in theswinging frames 3before referred'to and=iresting on the-form roller, and preferably a composit'ion: roller 29 'will beprovided mounted in:

the-frame 3 above-the metal-rollers andirest ingthereon. In the best-"constructions,- this roller- '29 will havea reciprocating movement imparted to it, which may :be' effected by means x of'theusual levers; 30 "and crank pin 31 on the 'endof "the shaft 24 before referred to;

Withcthe mechanism described ink may be supplled from'the fountain to the form roll Without the employment of the :usual lifter-roll: and; the mechanism for driving it: Furthermore, theamount of supply is easily. regulated by: adjusting the amount of rocking movement imparted-to the fountain roll, and furthermore the pressure of the form roll on the form cylinder is likewise readily adjustabl'aand the meansfor effecting the various adjustments areall readily accessible,- which is: a great advantage in inking mechanisms of this class.

While the invention has beenshownand.

described in its preferred. form,-it-.w'ill be understood that various changes may be madein the specific forms off mechanismsliow-n andzdescribed, and that: the invention is not to be restricted to such- -forms.
