INKING DEVICE FOR PRINTING-PRESSES.
SPECIFICATION forming part of vIlnetters Patent No. 447,021, dated February 24:, 1891.
' i Application led February 1, 1887. Serial No. 226,115. (No model.)
' To @ZZ whom it may concern:
Be it known that I, HENRY F. BECHMAN, a citizen of the United States, residing in Chicago, county of Cook', and State of Illinois,
have invented certain new and useful Improvements in Inking Devices for Printing- Presses, of which the following is a specificalLion. l
This invention relates to improvements in ro inking devices for printing-presses, particularly job-presses, in which the vibrations of the rocking frame or back legs carrying the chase and type-form are utilized for actuating the oscillatin g frame carrying the type-inking i 5 rollers.
The prime object of this invention is to have the type-inking rollers carried by oscillating frames or supports journaled upon the back legs and Working upon an hiking-plate 2o also secured to the back legs,havingacurved surface substantially concentric 'with the axis of the oscillating frames, whereby said rollers not only have a backward and forward travel upon the inking-plate between each contact 25 with the type, but by reason of their circular line of travel are not subjected `to undue and unequal pressure in traveling backward and forward upon the inking-plate,thereby greatly promoting the evenness of the distribution of 3o the ink both upon the plate and the type.
Another object is to combine with such oscillating frames and inking-plate a supplemental frame rigidly secured to and operated by the oscillating frame and carrying distributing-rollers for transferring ink from the ink-well and distributing it upon the inkiugplate in the path of travel of the type-inking rollers, whereby the latter take up a uniform coating of ink previously distributed and by 4o their own travel upon the iuking-platerender the distribution of the ink thereon still more effective.
Other objects are to promote the effectiveness of the distributing-rollers of such a printing-press by giving the rollers an endwise or lateral movement during their travel to and fro upon the curved inking-plate, to provide means for imparting to the oscillating and supplemental frames a unitary vibration upon 5o the axis of the frame, and to provide certain details of construction in the carrying out of my invention, all as illustrated in the accompanying drawings, in Which-- Figure 1 represents a side elevation of a press-frame, showing an inking device attached thereto embodying my invention; Fig. 2, a similar view of the opposite side of the machine; Fig. 3, a detail plan view thereof, and Fig. 4 a detail horizontal section through the shaft carrying the oscillating frame.
Similar letters of reference indicate the same parts in the several figures of the drawings.
Referring by letter to the accompanyingA drawings, A indicates the usual back legs or rocking frame of a printing-press, pivoted at the lower endV thereof to the mainframe B Y in the usual manner, to which rocking-frame at the top part thereof is secured an inkingplate O, bent onthe arc of a circlefandat- 7o tached at each end, respectively, by means' of bolts or otherwise. This plate, as before stated, is struck on the arc of a circleiia dupon. an axis common with that ofj `'the( ross-sh'aft'D, usually journaledin the back legs`,fto which a vibrating.movement is'inilpartedv and thereby communicated to the back` legs through the medium of pitmen or connecting-rods E, pivoted, respectively, to said shaft and to wheels FF, mounted in vthe frame B of the 8o press. The plate C consequent-ly y projects rearwardly from the back legs or to the'opposite side thereof, to which the chase and typeforin are secured. Y 1
Looselyjournaled on the shaft D is theusual 8 5 oscillating frame Gv, carrying upon one end thereof the type-inking rollers H, which are attached thereto in the same manner as ordinarily obtainsthat is, by spring-rods which hold the rollers at all times yieldingly 9o in contact with the typeI and inking-plate. Cast with or otherwise rigidly secured to said oscillating frame and projecting at substantially right angles thereto is a supplemental frame I, also carrying rollers J, secured thereto in substantially the same manner as the type-inking rollers, this supplemental frame,
as well as the oscillatin g frame or support, bc-
ing duplicated on the opposite side of the machine, so as to furnish bearings at each roc side for all the rollers. These rollers J cxtend transversely across the inking-platc C, and are designed solely as distributing-rollers, to further which end the bearings thereof carried by the supplemental frame at each side of the machine are set at an oblique angle to their line of l travel and to each other, so that the rollers extend obliqnely across the inking-plate, with the spindles K thereof elongated and Working freely through their bearings in such manner that during the travel of the rollers to and fro upon the inkin gplate they will have a lateral or endwise as Well as rotary movement, one toward the right and the other toward the' left of the inkingplate, induced solely by the frictional contact of -said rollers with the plate. Although the distributin-geffect of these rollers, if j ou rnaled at right angles to their line of movement, would be greater than is possible to attain in any of the prior constructions, it is materially aided by this lateral or endWise movement in distributing or equalizing the coating `of ink over the surface of the inlxing-plate, to further which Vend a second pair ofrollers L are provided, of less diameter than the rollers J and mounted directly over them in any extension of their bearin gs,by which the ink is taken from the transfer-roller M of the ink-Well. This ink-Well,though of substantiallythe same construction as th at upon which Letters Patent of the United States, No. 345,760, was granted meis somewhat different in its operation and location, the transfer-roller M being above instead of below the ink-Well roller N, While the gravity of the latter acts in conjunction with the spring O to throw it into contact with the ink-Well roller. In this case also the ink-Well, instead of being stationary, as in my said patent, .has a bodily travel back and forth by reason of its attachment to the back legs, the cam-lever P being curved upwardly at its `outer end and engaging and riding upon a pin or projection Q, secured to the frame B, so as to obtain its vibratory motion relative to the ink-Well, thereby imparting a partial ro` tation to the well-roller N by reason of the engagement of a pa'wl R, secured thereto, with a ratchet-Wheel S, mounted upon the spindle of 'said roller, upon which the cam-lever is loosely Vjournaled,at the same time elevating the transfer-roller M clear of the Well-roller' and partially into the path of the rollers L L by means of a cam projection T on said lever engaging the projecting end of the spindle of said roller at each and every vibration of the back legs. For the Vpurpose of actuating the oscillating and supplemental frames, I have mounted rigidly upon the elongated hub U of one of the oscillating frames a small cog-Wheel V, the teeth of which engagea segmental rack XV, secured to the frame B, the outer end of which rack is held rigid by a brace X, also secured to the frame B, thus giving to the rack a triangular base-support. The oscillating frame, being loosely j ournaled upon the cross-shaft D, is caused to oscillate during the vibrations of the back legs by reason of the engagement of this cog-Wheel V with the stationary rack, which of course is struck on the arc of a circle havinga common axis with the pivot of the back legs, the two castings or frames which I have designated the oscillating frames, being connected together and oscillating in unison by means of the tie-rod Y, extending between the supplemental frame acting in conjunction with the supporting cross-shaft.
Having described my invention, what I claim, and desire to secure by Letters Patent, 1sA
l. AThe combination, with the back legs, the inking-plate, the oscillating frames, the supplemental frames rigidly secured to and proj ecting at an angle from said oscillating f rames,an d the inkin g and distributing rollers journaled in said frames, respectively, of the fixed rack, the cross-shaft, the gear mounted thereon and meshing with said rack, and the pitman supported by said cross-shaft, substantially as described.
2. In an inking device for printing-presses, the main frame, the back legs, an inkingplate having a curved flat surface secured to said back legs, the oscillating frame, and distributing-roller mounted in said frame, in combination with the ink-Well secured to said back legs, the Well-roller, the movable transfer-roller, a cam-lever for actuating said transfer-roller, and a pin or projection on the main frame engaging-and actuating said lever, substantially as described.
