ADJUSTABLE INK-IPUMP BAIL.

Application filed January 14, 1926. Serial No. 81,196.

This invention relates to certain improvements in inking mechanism for printing machines, and is designed particularly for use with the type of mechanism shown in United States Patents No. 1,214,856, dated February 6, 1917, and No. 1,311,198, dated July 29, 1919, both to B. C. White.

In the type of inkingmechanism shown in these patents, the ink is supplied through a series of separate conduits, one conduit beingi provided for each column or other desire section of the form to be inked, this ink being delivered under pressure in the desired quantity by a plurality of independent pressure devices, such as pumps, one of these pressure devices being provided for each conduit so that the quantity of ink delivered to each column or section may be varied as desired.

In producing certain products, as, for instance, an illustrated page or a page the printed matter of which is chiefly illustration, it may be desirable that the ink supplied to such page be greater or less than the ink supplied to other parts of the form or forms, and it is desirable for quick and speedy adjustment that the ink supply for iuphda page may be readily and quickly regua e 30 It is a special object'of the invention to provide a construction by which the thick nessof the ink film from the conduits supplying a page may be increased or decreased throughout the whole width of the page, this adjustment'being such that it can be effectedby a single adjusting movement, so that a quick and eflective ink adjustment can be made.

A further object of the invention is to produce. such a construction in which the parts are readily accessible and in which the adjustment can be efiected from a conveniently central point in the machine.

With these andother objects not specifically referred to, the invention consists in certain novel parts, arrangements, and combinations which will be fully described in the accompanying drawings and the novelfeatures pointed out in the claims hereunto annexed.

The accom anying drawings show one construction or efiecting the objects of the invention and in these drawings,

Figure 6 is a detail side view of one of the adjusting members, and

Figure 7 is a detail face view of the con;- struction shown in Fig. 6.

Referring now to these drawings, one printingccou 1e is-diagrammatically shown including a term cylinder 1 and an impression cylinder 2 printing on a web W, these cylinders being suitably mounted in sideframes 3.

The particular machine selected to illustrate the invention is a rotary,machine in which both "members of the printing couple are cylinders, but it willbe'understood that the invention as to. certain of its features will be useful in other types of machines and in machines in which both elements of the couple are not cylinders, and it will also be understood that the inking mechanism is provided as necessary or desirable in multi-couple machines.

In the particular construction illustrated, the form cylinder 1 is inked from a pair of distributing rolls 4, 5, which take ink from a drum, 6 to which ink is supplied from a roll 7 which receives "ink from the inking mechanism indicated generally \by the numeral 8.

In the particular construction shown, the forms tobe inked are four plates arranged widthwiseof the cylinder 1, each plate being eight columns wide. Ink is supplied from the inking mechanism 8, under pressure, by suitable, pumps, not shown, through 1 a plurality of conduits, one of these conduits being provided for each column or other section of the form, thirty-two of these conduits, marked 9,being provided in the present instance, corresponding to the thirty-two 11W 1 these nozzles lying closely adjacent the roll.

conduits carrie .The ink rail is formed with a downwardly extending portion 15, below the nozzles,

which is curved to a proximately thegcurveof the distributor r0 1 7 and lies closely adjacent thereto, this portion of the rail actm to regulate the ink delivered to the roll. 11 accordance with the invention, means are provided for manipulating the rail so that the distance between the distributing face 16 of the part 15 and the roll may be varied, so as to permit an ink film of different degrees of thickness to be taken away b the distributor roll. These means are suc 1 that the ink distributed by a plurality of the conduits may be simultaneously adjusted without effecting that distributed from other conduits, and the means for effecting this will be conveniently arranged for the operator, as by locating the adjustin mechanism-at one side of the machine so t at any desired ad- 'ustment can be made from one point. While the specific construction for effecting this may be varied with considerable limits, that illustrated is a convenient one. As shown, the distributing art of the ink rail is divided into a plum ity of sections which are'mounted so as to be movable independently of each other toward and from the distributin roll. While the number of d by each section may vary as desired, in the particular construction shown there are four such sections, marked 17, 18, 19 and 20, each one of these sections carrying eight distributing nozzles 13 for eight columns or sections of the form, such number in the present instance making up a one page width, so that by adjusting one of these sections the ink supply to any particular page is regulated as may be desired. It will be understood, however, that the rail may be divided into as many sections as may be necessary or desirable, an operating mechanism for each of the sections being provided as hereinafter referred to.

In the particular construction illustrated, these sectlons which form art of the ink rail. are .made independent 0 each other and independent of the rail and have a sliding movement relatively to the main part of the rail 11 before referred to, and toward and from the distributing roll 7 .Inthe particular ,constructionshown, therefore, these sections 17-20 are provided with a rearward extension '21 which has a sliding movement on a projecting portion 22 of the rail, thesections being gulded in their movement on suitable guides 23 extendin intothe rail 11 and the downwardly extending distributing portion 15, before referred to. These sections are given a sliding movement in any suitable manner.

In the (particular construction shown, this is etfecte by certain rod and gear constructions, the operating mechanism for which may be centrally located at a convenient point at one side of the machine, an operating' mechanism for each section being provided. As shown, each section has secured thereto a bracket 24 provided with a leg 25 which receives the end 26 of a threaded adjusting screw 27 which is'-tapped into a socket in the extension 22 of the fixed part of the rail 11. This threaded screw 27 carries agear' 28 which'meshes with a gear 29 on one end of a shaft 30 mounted in suitable bearings 31 on the rail 11', before referred to. The outer end of this shaft 30 is be seen that by rotating the operating wheel 36 the section controlled therebyis given a movement toward and from the distributor 7, thus adjusting the width of the ink ga between the distributor face 15. of the 1n rail andthe distributor roll 7, so that more or less ink is taken away and deliveredby the distributor roll. With this construction it follows that the adjustment can be made without changing or adjusting the pumps, it being understood that the conduits 9- are sufficiently flexible to permit this adjusting movement without injury thereto. As the amount of this adjusting movement is very slight, a speedy and effective adjustment for the ink widthwise of the distributor roll 7 is, therefore provided, and one which can be convenient y made from a central point of the machine.

Oooperating with the inkrail is a. cover plate or cap,37 which covers the nozzles 13. To permit ready access to the conduits,

'this cap or plate is arranged so it' can be ,and-is held in closed positionby springs 39., The various parts of. the inking mechanism may be supported in' the side frames 3,

before referred to, and the pumps may be conveniently mounted in the fountain casing, indicated enerally by the numeral 8.

' While t e invention has been shown and described in its preferred form, it will beunderstood'that certain changes and variatipns may be made in the specific construction described and in the arrangement of the ink rail without departing from the invention as defined in the claims hereunto appended.
