Application filed March 15, 1913. Serial No. 754,539.

To all whom it may concern." I A Be it known that I, JOHN MCGLU'RE, a citizen of the United States of America, residing in Glenside, in the county of Montgomery and State of Pennsylvania, have in vented certain new alld useful Improvements in Inking Mechanism for Prlntlng- Presses, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My present invention relates to apparatus for supplying ink to printing presses, and particularly to inking apparatus of the kind in which the ink is contained in an ink receptacle or reservoir, adapted to be removably inserted in feeding apparatus which is attached to the printing press, and comprises means for expelling ink from the receptacle at the desired rate.

My improved inking apparatus is primarily devised for and is especially adapted for use with job printingpresses which are operated intermittently, or at least not operated continuously with one kind of printing ink. "With my improved inking apparatus when a printing operatlon requiring the use of ink contained in one receptacle is finished, the receptacle may be readily removed, and when the next printing operation is to take place, the same receptacle or a similar receptacle containing the same or a different kind of ink may then be inserted in the apparatus. Each receptacle may thus be intermittently used until all the ink initially inserted therein is used, up. This type of inking apparatus comprises the general advantages of keeping the ink, fully or partially filling the receptacle, clean and of protecting it for long periods fro-m exposure to the atmosphere tending to dry out and 0x1- di-ze the ink. Furthermore, it is inherently adapted to keep the ink wastage down to a practical minimum. 0

The general object of my invention is to provide apparatus of the character referred to which shall be simple in construction, relatively inexpensive to manufacture, and reliable in operation. of my invention are to provide apparatus which can be readily applied to existing printing presses of various types, which can be cleaned with a minimum expenditure of time and labor, which permits the rate at which the ink is fed to be adjusted quickly and readily, and which comprises simple and More specific objects effective means for preventing injury to the apparatus in case all the ink is expelled from the ink receptacle in use while the printing press is in operation. A further object of my invention is to provide a simple and inexpensive type of ink receptacle'for use in and as a part of the ink feeding apparatus proper.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and of the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described various forms in which my invention may be embodied.

Fig. 12 is an elevation of a portion of the feeding shaft employed in Fig. 11; and

Fig. 13 is a partial end elevation of still another form of feeding mechanism.

The well known form of printing press illustrated somewhat diagrammatically and conventionally in Figs. 1 and 2, comprises a stationary frame A, carrying a vertical platen A, and having pivotally connectedto it at B a swinging presser head '13 carrying a form B The presser head B is oscillated on its fulcrum pivots B by means of links C connecting the fulcrum pivots B to crank pins C carried by crank disks C which are mounted on a shaft connected by gearing (not shown) to the main driving shaft C of the press. An oscillating frame D pivoted on the trunnion pivots B is caused to turn on the latter as the presser head B swings back and forth, by the link connections D between the frame D and the pivot pins A carried by the frame A. At its upper ends the frame D carries the usual form rolls D by which the printing ink is transferred from the inking bed of the press to the form 13 The inking bed is in the form of the usual rotary inking disk D.

The apparatus for supplying ink to the disk E comprises a roll J which I may call a fountain roll, mechanism for rotating this roll, mechanism for expelling ink at the desired rate from an ink receptacle S against the roll J, a transfer or feeding roll M, and mechanism for moving the transfer roll back and forth between one position in which it contacts with, is rotated by, and receives ink from the fountain roll J, and another position in which it contacts with and applies ink to the ink disk E.

As shown in the drawings the inking apparatus proper comprises a frame G secured at one end to an arm F, which is suitably affixed at its other end to the presser head B of, the press. As shown, the frame G is secured to the bracket arm F in the desired adjustment with respect to the ink disk E by means of a central stud or bolt F and a set of leveling screws F The main power shaft II of the inking mechanism proper is journaled in the frame G. This shaft is given an oscillatorymovement by suitable connections to some moving part of thepress proper. As shown in the 'drawings, the shaft II is connected to the oscillating frame D by means of an arm II secured to one end of the shaft II, a clamp H detachably secured to a portion of the frame D, and a connecting rod H pivotally connected at one end to the clamp H and at the other end to the arm H. The shaft H carries at its other end a gear sector I, which meshes with a spur gear J secured to a shaft 5 also journaled in the frame G. The shaft J carries the fountain roll J, which is detachably secured to the shaft as by means of the set screw J. The roll J is preferably formed of metal and is advantageously so mounted as to have freedom for a limited amount of axial movement and if desired some suitable or usual form of end play device may be employed to give it a limited amount of axial movement as it is rotated first in one and then in the opposite direction. Each oscillation of the frame D preceding each impression made by the Printing press imparts a corresponding oscillatory movement to the shaft II and the sector I. The oscillatory movement imparted to the sector I- is suflicient to give several turns to the fountain roll J, first in one direction and then in the reverse direction. As the sector I, moving from the position shown in Fig. 2-, ap, proaches the'position shown in Fig. 1, a lug or projection I carried by the sector I en} gages a pin or projection K carried by an arm K, and thus imparts an oscillatory movement to the latter and, to the shaft K to which the arm.K is attached. At, its, free end the arm K is formed with an open ended slot K receiving a pin L secured to the U frame L, and adapted tosl-ide in the guideways formed by the lugs G of the frame G. The transfer roll M, which may be a composition roll, is journaled in the forward ends of the frame L. The movement imparted to the frame L by the oscillation of the arm K is suflicientto move the roll M from its normal position, shown in full lines in Fig. 2 in which it is in contact with and rotated by the fountain roll 1, into. its second position in Whichit contacts. with the inking bed ordisk E, as shown in dotted lines in Fig. 2. Springs L? operate to return the frame L to the position inwhich the roll M contacts with the fountain roll l when the return movement of the sector I permits.

The shaft K serves as means for transmittin motion to the ink expelling mechanism. For this purpose an arm K is secured to one end of the shaft K. A sleeve N slid in gly mounted on the arm K and adj ustably. 105 clamped to the latter as by means of the thumb nut N'carries. a crank in N The latter is connected to and. oscillates a pawl leverP by a connectingrod. Normally this connecting rod serves as a rigid connection. 11( between the crank pin and the pawl lever P, but the connecting-rod is adapted to serve as a safety device which will yield or collapse on a predetermined increase in the resistance to the oscillatory movement of the 11S pawl lever P. For this purpose the con necting rod is formed in two main sections 0 and O. The section O is pivoted at its lower end on the crank pin N and is formed at its bifurcated upper endwith cam slots 120 0 receiving a stud O secured to the. lower end of the upper main section 0 which extends between the bifurcations of the section O. The section 0 is pivoted at its upper end to the pawl lever P. The upper end V O of one bifurcatiorrof the lower section extends at right angles to the length of they section and normally abuts, against an arm O pivoted at Otto the section OQ The arm O is normally held in the position shown in Fig. 2 in which it bears against the flat end 0 of the section 0 by a spring 0 When the resistance to the feeding move ment of the pawl lever P exceeds a predetermined movement, the spring 0 yields and the two sections 0 and O of the connecting rod start to move relatively to one another in a direction parallel totheir lengths. The inclined direction of the slots 0 however, cams the meeting ends of the two sections laterally apart and after a slight initial telescopic movement. the connecting rod breaks or collapses into the position shown in Fig. 5. On the return movement of the apparatus, the connecting rod 0 straightens out again and snaps into its original condition, and this yielding and subsequent straightening out of the connecting rod continues on each up and down stroke of the arm K until the resistance to the oscillatory movement of the pawl lever P is reduced to the normal amount. A strap G is adapted to arrest the backward motion of the pawl. lever P and insure the straightening out of the connecting rod 0, O on each downward swing of the arm K.

The pawl lever P is mounted to oscillate about the axis of a shaft Q. The latter carries a ratchet wheel Q which is engaged and given a partial turn by the pawl P carried by the lever Pon each upward movement of the latter. The pawl 19 pivoted to the frame Gr engages with the ratchet wheel Q to preventretrograde movement of the latter. The shaft Q is formed with a worm Q which is in mesh with a worm gear Q The latter surrounds and is splined on the piston rod or feed bar R. The feed bar R is received in the guideway Gr formed in theframe G and is threaded for engagement with the half nut GA which is detachably secured in place in the frame G as by the pivoted latch G With the arrangement described the rotation imparted to the feed bar R by the rotation of the gear Q slowly advances the feed bar B so long as the threads of the latter are in engagement with the half nut GA. When the latter is moved out of place, however, the feed bar It may be moved parallel to its length in either direction without rotation of the gear Q A handle Q secured to one end of the shaft Q forms a means for manually rotating the shaft Q to facilitate the registry of the threads of the rod R and half nut GA in securing the latter in place. With the half nut GA in lace, the feed bar R may be manually advanced without oscillation of the pawl lever P, by means of the handle Q}. At its lower end the'feed bar R carries a suitable piston R which enters the open upper end of the ink receptacle S.

The latter, in the form shown best in Figs. (3 and 7, comprises a sheet metal cylinder closed at its lower end, except for'apertures S, and open at its upper end. To the lower closed end of the receptacle S is secured a head ortion T which is formed with a concavity or shallow groove T curved to correspond to the curvature of the fountain roll J, which in the assembled apparatus, extends into, but does not contact with the surface of this concavity as shown in Fig. 2. In the particular construction shown in Figs. 6 and 7, the member T is cast, and is secured to the end of the cylinder S by solder plugs T which are formed with apertures T registering with the apertures S in the closed end of the ink receptacle S. This method of securing the head T to the receptacle S insures a very satisfactory and easily made connection which, while reducing the amount of soldering required, avoids all possibility of leakage along the joint between the member T and the end surface of the receptacle against which it abuts. The receptacle S rests against a suitable seat G formed in the frame G and is held at the desired distance from the fountain roll J and is prevented from rotation by means of the frame part G which fits against the closed end of the receptacle and also against one side of the rib In the use of the apparatus described, the frame is so connected to the part B of the printing press that the transfer roll M'will contact with the ink bed E in the dotted line position of the parts shown in Fig. 2, and while moving between the dotted and full line positions of Fig. 2 except when in close proximity to its full line position in which the roll M is in engagement with the fountain roll J. By the described connections between the rock shaft H and the frame D the rocking movement of the latter causes the rock shaft H and parts connected thereto to swing back and forth between the positions shown in Figs. 1 and 2. Inasmuch as the gear segment I meshes with the spur gear J 2 at tached to the fountain roll J, any rocking movement of the shaft H in either direction causes a rotary movement in the one direction or the other of the fountain roll. As the gear segment I in turning from the position shown in Fig. 2 toward the position shown in Fig. 1 approaches the last mentioned position, the projection I of the gear segment I engages the arm K and thus gives a partial turn to the shaft K and at the same time through the engagement of the arm K with the studL of'the movable frame L advances the latter from the full line position of Fig. 2 into the dotted line position of that figure. The oscillation of the shaft K through the arm K connecting rod 0 and the gearing actuated by the latter, imparts corresponding downward movement to the ink expelling plunger R. The eXten-t of the movement 61511 receptacle proper-with an external support.

or feed imparted to the plunger R at each oscillation of the gear segment I may be adjusted by adjusting the distances from the axis-of the shaft K at which the sleeve N is secured to the arm K. As the gear segment I moves back from the position shownin Fig. 1; into the position shown in Fig. 2 the springs L return the movable frame Land thereby the arm K, shaft; K and attached parts to the position shown in Fig. 2. The gear J and gear segment I are so proportioned that a partial turn of the latter. will give several complete turns to the roll J, and inasmuch as the transfer roll M is not moved out of contact with the roll J'- eXcept during a small portion of the oscillatory movement of the gear segment I, the roll J will give several turns to the roll M While the rolls J and M are in contact and thus insure a proper transfer of ink from the fountain roll I to the dis tributing roll M. The reversal of the direction of rotation of the rolls J and M and the freedom for endwise movement of the roll J contribute to the desired evenness with which the ink is transferred from the roll, J, to the roll M. In case the apparatus continues in operation after the piston R engages the lower end of the ink receptacle,

the yielding connection formed by the jointed, connecting rod 0 then yields on each feeding movement of the shaft K, and thus prevents injury to the apparatus. The film-like space provided between the fountain roll J and the wall of the groove formed in the end of the receptacle serves as a distributing space for spreading the ink discharged into this space through the orifices D i It will be readily apparent that one ink container may be removed and another inserted quickly, and easily, and that the apparatus is readily cleaned.

Instead of having the rib T formed separately from the body of the ink receptacle, the receptacle itself may be formed from sheet metal pressed into shape as shown in Fig. 8, wherein S represents the groove or concavity formed in the closed end of the sheet metal receptacle SA to receive the fountain roll J, and S represents an aperture through which ink is expelled onto the 1'01]. J.

When it is desired to avoid the cost of sheet metal ink receptacles, they may be formed of paper or paste board. In this case I preferably provide a metal head or cap, as shown in Fig. 9, wherein TA represents the metal cap and SB the paste board receptacle which is in the shape of an open ended cylinder. To prevent undesirable yielding of the paste board cylinder under the pressure to. which the ink is subjected by the piston R, I prefer to provide the 1 ,zaepos.

This may be in the form of a sheet metal sleeve U. As shown in Fig. 9, the sleeve U may advantageously be slotted at one side and proportioned to snugly hug the inclosed paste board cylinder. To permit the ready insertion and removal of; the paste board cylinder the. sides of the slot U? may be sprung apart by means of an inserted screw driver or like implement. In place of such a holder as is formed by the slotted sleeve U shown in Fig. 9,. I may employ the holder UA shown in Fig. 10. This holder comprises a base member formed with a semi-cylinch 'ical channel receiving the ink receptacle proper and a top member U" hinged to the base member at one SlClG as indicated at U and detachably secured at its opposite side, as by means of the clamping screw U to the base member.

It will of course be readily understood that other means than those heretofore described may be employed for giving the feeding movement to the ink expelling piston. For instance, as shown in Figs. 11; and 12, the shaft Q. may be replaced by a shaft QA formed with angularly displaced crank portions Q, on which are journaled pawls IV adapted, when the shaft QA is rotated, to intermittently and successively engage and advance the feed bar carrying the ink expelling piston. The feed bar in this case is a rack bar RA. Another construction of the feeding mechanism is illustrated in Fig. 13, wherein the feeding mechanism may be identical with that employed inFigs. 1 to l, inclusive, with the exception that the shaft Q is replaced by a shaft QB formed with crank portions for intermittently. and

successively advancing pawls W and W and the gear Q is replaced by a disk X splined on the threaded piston or feed rod R and formed on its face with two annularly arranged seriesv of ratchet teeth X and X engaged one by the pawl W and the other by the pawl VV Q lVhile in accordance with theprovisions of the statutes I have illustrated and described the best forms of my invention now known to. me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention, and that under some conditions certain features, of my inventionmay be used without a corresponding use of' other features.
