INKING APPARATUS FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 494,096, dated March 21, 1893.

Application filed August 12, 1892- SerialNo.442,923. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH L. COX, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Inking Apparatus for Printing-Presses; and Ido hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form part of this specification.

This invention is an improvement in inking devices for stationary bed and reciprocating cylinder printing presses, and is especially designed for use with web printing perfecting presses, having one bed horizontally over the other and parallel therewith, such as is shown in my Letters Patent No. 478,503, granted the 5th day of July, 1892.

The objects of this invention are first to supply ink to distributing rolls at each end of the bed, from a single ink fountain; second, to locate this fountain at one end of the bed and exterior to the distributing rolls where it will be readily accessible; third, to transfer ink from one distributing roll to the other by means of a reciprocating transfer roll, preferably suspended from cylinder carriage; but moving beneath the bed. In brief to provide inking devices whereby from a single fountain ink may be intermittently supplied to ink distributing rolls at opposite end of a type bed; and the ink thoroughly disseminated and distributed by proper rolls prior to being taken up by the form rollers, which will ink the forms on both the forward and backward movement of the cylinder, whereby two impressions may be taken from freshly inked type .at each reciprocation of the cylinder.

The invention therefore consists in the novel combination of stationary distributer rolls at opposite ends of a type bed, with areciprocating roll alternately contacting therewith but not contacting with the type forms on the bed, and the same in combination with a single fountain and a ductor for transmitting ink to one of the distributer rolls, and in certain other novel details of construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of the bed portion of a web perfecting press constructed substantially like that described in my aforementioned patent, and having my improved inking apparatus applied. The press having two type beds, the

in king apparatus therein is simply duplicated.

Fig. 2 is a top and partly sectional view of a set of inking apparatus detached. Fig. 3 is a detail transverse vertical section of one set of ink rolls. Figs. at and 5 are detail views of the bearings of roll 1). Fig. 6 is a detail which is carried between the lower cylinder and bed, and thence up and between thesec- 0nd cylinder and bed being guided by suitfiv able rollers on the frame and carriage as in-.

dicated in the drawings, all substantially as set forth in my patent hereinbefore referred to.

A designates an ink fountain secured opposite the outer end of each bed. 7

O and G are ink distributing rolls journaled in proper bearings at opposite ends of each bed, and B is a ductor roll journaled in vibrating arms 6 adapted to alternately contact the fountain roller and roll 0 to supply ink to the latter.

D, D are distributing rollers journaled in proper bearings beside the respective rolls 0, O to the inner side thereof and below the bed, and E, E are vibrator rollers contacting respectively with rolls 0, O and journaled above rolls D in position to contact with the form rollers F, F journaled in proper bearings on carriage 5 at each side of the cylinder as shown.

d represents a transfer roller which is reciprocated between rollers D, D and transmits ink from one to the other, rollers d, d, moving beneath the beds and out of contact therewith.

This is the general arrangement of parts,

and the rolls may be mounted and driven in any suitable manner; and by this arrangement I supply ink from a single fountain to two sets of distributing rolls'at opposite ends of a type bed, by means of a single transfer roll moving beneath the bed.

The inking devices, are as shown, operated as followsz-Rolls C are driven by trains of gearing g, g, g, from a transverse shaft G which operates the looper in my patent above mentioned at one side of the machine. On the opposite end of shaft of roll 0 is a bevel gear 0' which meshes with a bevel gear h on a shaft H lying at right angles to, and in the same plane as rolls 0 and journaled in proper bearings attached to the main frame or type bed, and on the other end of said shaft is a similar bevel gear h meshing with a bevel gear a on the end of roll 0, so that the rolls C, O are similarly speeded.

Rollers D, D are journaled at one end in trunnioned boxest'attached to the side frames of the press, and at their other end are journaled in hinged boxes I which are locked by hinged screws 1 by loosening which the rollers D, D can be let away from rolls 0, C (desirable when the press is not running) and can also be conveniently removed and replaced. The opposite ends of rollers E and E are journaled in boxes J and K the former of which are fixed to the frame but the latter are slidably mounted on brackets 76 fixed to the frame also, so that rollers E, and E may be longitudinally vibrated, by means of pltmen L which are connected at one end to boxes K and at the other to eccentric straps Z on eccentrics m formed with gears M and journaled in stub shafts or bolts N,N, fixed to the sides of the type bed or other suitable support, as shown in Fig. 2. The gears M mesh with pinions H on shaft II. The shafts O on which vibrator arms I) are mounted are provided with crank arms 0, 0, which are connected by pitnien P, and the lower shaft 0 has another crank. arm 0 which is connected to the end of a pitman rod Q the forward end of which is connected to, or operated by an eccentric or cam on shaft G, substantially as indicated in Fig. 1.

Operation: The ink 1s taken first from fountain A by the intermittently reciprocating ductor B which deposits the ink upon the drum G where it is thoroughly disseminated by the rotation and contact of the distributer D, and vibrator E. The form roller at proper intervals (as the carriage 1s reciprocated) comes in contact with the drum O upon which it rotates more than a revolution and then returns with each stroke of the carriage passing over the forms of type thereby inking the same sufficiently, and in substantially themanner described in my patent referred to, wherein I show an ink belt. The transfer roller (1 which may be of wood, as the carriage reciprocates comes in contact and r0- tates with the composition distributing roller D, and with the return of the carriage returns to the opposite end of press and trans fers or delivers its supply of color upon the other distributing roller D, the rotation of which brings the fresh supply of ink in contact with the various distributingand vibrating rolls at this end of press, from which it is taken off and transferred to the form by the form roller F on the opposite side of the cross head from that heretofore described.

The mechanism and operation of inking devices for both upper and lowerbeds are practically the same.

Having described my invention, what I claim as new, and desire to secure by Letters Patent thereon, is

1. In a printing press, the combination of a type bed, and ink distributing rolls at each end thereof; with a transfer roller adapted to be reciprocated out of contact with the type to transfer ink from one set of rolls to the other, substantially as specified.
