INK-DISTRIBUTING MECHANISM.

To all whom it may concern:

Be it known that I, EDWARD J. F. Rm, a citizen of the United States, residing at Hartford, in the county of l-Iartford and State of Connecticut, have invented certain new and useful Improvements in Ink-Distributing Mechanism, of which the following is a specification.

This invention relates to ink-distributing mechanism for printing presses, the principal object of the invention being to provide effective means of this character by which the ink can be uniformly distributed.

The apparatus comprises other features of novelty and advantage which with the foregoing will be set forth at length in the following description wherein I will outline in detail two of the several forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part of the present specification, this disclosure being provided to enable those skilled in the art to practice the invention. From such observation it will be evident that I do not restrict myself to said disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a side elevation with parts removed, of a printing-press equipped with inledistributing mechanism involving my invention. Fig. 2 is a sectional side elevation of the rollers with certain of their operating parts. Fig. 3 is an elevation of the parts shown in Fig. 2 as seen from the right thereof, with the central portions of said rollers removed. Fig. 4t is a somewhat similar view with certain of the operating elements removed, and only the ends of the rollers being shown. Fig. 5 is a top plan view of the parts shown in Fig. 4. Fig. 6 is an inside face view of a supporting box, which sustiins the rollers at one end. Fig. 7 is a perspective view of the boxes assembled and which support the other end. of said rollers. Figs. 8 and 9 are like views of the boxes shown together in Fig. 7 separated from each other. Fig. 10 is a top plan view of a different form of roller mechanism, and Fig. 11 is a sectional view of the same.

Like characters refer to like parts throughout the several views which it will be perceived are on different scales.

Specification of Letters Patent.

Application filed September 19, 1912.

Patented Sept. 23, 1913.

Serial No. 721,224.

At the outset I wish to make it clear that my im 'n'oven'lcnts can be used with MlVfllb tagc in various mnnections; for instance the same may be incorporated in. a printing or a lithographing press. In Fig. l of the drawings I have illustrated for convenience in il'ulicating the utility of the improved organization, a press of known construction, certain of the well known parts of which will be briefly described, and which embodies mechanism including the invention. Said press has its different (merative parts sustained by framework, such as that denoled in a general way by 2. The powershaft 3 is carried by suitable bearings on the sides of the framework, and may be driven in any desirable manner, for example by the pulley or belt-wheel i. In the construction shown, the moving parts of the ink distributing mechanism, receive their motion from said I)()\V0lf-sll2tfil 3 although in all cases this is not necessary. I will here inafter describe the connections between said shaft 8 and said inkalistributing mechanism, but I do not limit myself thereto. The press is shown equipped with a reeiprocatory inktable 5 which receives ink at one end thereof from the font (3. Jointed to the underside of the ink-table 5, is the pitman or connect ing rod 7 pivoted to a ta'ank-arn'i S on the shaft 9 provided with a spur gear 10 in mesh with the pinion 1 'l of the main shaft It will therefore be understood that as said power-shaft rotates, the table 5, through the intermediate described parts will be caused to reciprocate all as common in the a t.

There are preferably at least two inkdistril'iuting rollers one arranged above the other, the lower roller being rotated by frictional contact with the bed 5 while said lower roller in turn frictionally drives the upper cooperating roller in the opposite direction. In the construction shown there are three of said lower rollers and three of said upper rollers. The lower rollers are denoted by 12, 13, and 14. while the upper rollers are designated by 15, 16 and 17 respectively. It will be evident that the three lower rollers are rotated by direct contact with the reciprocatory bed while the upper rollers are turned by contact with the respective lower rollers. Each upper roller is reciprocated oppositely to a cooperating lower roller, as will hereinafter appear, to thereby better distribute the ink and power-operable means transversely of the machine, the fr amin preferably including a rack and oscillatory or rocking pinion, is provided for this purpose, said means being positive and certain in action and as already intimated being preferably operable from the main or power shaft 3, as will hereinafter appear.

All the rollers are confined against lateral movement at one end by a box or standard such as that denoted by 13 (Fig. 6,) which is rigidly mounted on the frame work of the press, said box as shown having channels 19 to receive the outer end journals 20 of said rollers. Three of such rollers 12, 14: and 16 reciprocate together as a set, the other three rollers 13, 15 and 17 reciprocating also as a. set and oppositely to the other set by virtue of which each roller is always when in endwise action, moving oppositely to the contacting roller. Tn mounting the several rollers, the journals 20 are dropped into the channels 19 through the upper open ends thereof.

There are two boxes or bearings which support the other journals of said six rollers and one of them fits slidably within the other both being slidable or reciprocative g of which has suitable bearings therefor. One of said slidable boxes is denoted by 25 and the other by 26, the box or hearing 25 fitting within the box 26 as shown best in Fig. 7. The box 25 comorises in its make up a substantially yoke-like booy 27 provided with lateral extensions 28 on the upper ends of its side branches, said extensions and. the

transverse portion of said body 27 having.

slots 29, T shaped in cross section, to retatably receive the correspondingly-shaped adjacent journals of the rollers 13, 15 and 17. The block or bearing 26 is of substantially inverted yoke form and from theends of the sides thereof there are extended inward the square projections 30 and 31, the crossbar thereof having a depending similar projection 32, said several projections 30, 31 and 32 having T slots 33 to receive the T shaped adjacent journals of the rollers 13, 14- and 16. It will therefore be apparent that each of said blocks or boxes 25 and 26 acts to reciprocate three of the ink-distributing rollers. The heads or transverse portions of the ournals supported by the blocks or boxes 25 and 26 are of disk orcircular form so as to insure the reciprocation of Said rollers but not to effect the free rotation thereof. The block 25 is provided with an outwardly-extending rack-bar 34, while the block 26 is equipped with a practically similar rack-bar 35, the teeth of the two rackbars being in mesh with the intermediate pinion 36, it being understood that the two groups of rack-bar teeth face inwardly or toward each other. As will hereinafter appear this pinion 36 is rocked and as it is thus operated the two set-s of ink-distributing rollers through the invention of the described parts, are reoiprocated in the manner already set forth. The framework of the machine is furnished with a guide as 37 for the rack-bar 38 which teeth, one set of teeth being in mesh with the pinion 36 and the other set being in mesh with the pinion 39 fastened to the shaft 40. Said shaft 40 also-rigidly carries the pinion 41 the teeth of which are in mesh with teeth on the reciprocatory rack bar 42 upheld by a stirrup 43 suspend ed flexibly from the shaft 40. The rack-bar 4L2 terminates in a strap A surrounding the eccen ric e5 on the shaft 9 which I have already described. It will therefore be evident that when the press is in action, the ink-table 5 is recipmoated, thereby rotating directly the lower set of ink-distributing rollers while at the same time said lower rollers by contact, rotatebppositely the re spective upper rollers. At the same time, three of said rollers are being reciprocated in unison with each other whilethree other of said rollers are being simultaneously re' ias two sets of In Figs. 10 and'll I show a different mounting of ink-distributing rollers, there being as in' the other cases three lower rollers and three upperrollers denoted by 50. Each roller has at one end a journal 51 having a T head 52, said T heads fitting. for rotation T slots '53 1n the bearing blocks 5 1, there being three lower bearing blocks and three upper bearing blocks, the upper bearing blocks being supported for sliding movement by the lower bearing blocks.

slidable within the skeleton and substan tially rectangular frame or carrier 55 mounted on the main frame of the machine. Said blocks bemg slidable in the direction of the axes of rotation of said rollers 50.

the pinions 58 and 59, which mesh with the teeth of the two pairsof outer racks, the 7 two intermediate racks being'in mesh with the pinion 6O fastened to the shaft 61 also supported by suitable hearings on the framework of the machine. Fastened to the shaft 61 is the second pinion 62 in mesh with the wide faced or barrel pinion 59. Connected with the shaft 61 is the rock-arm 63 which is oscillated exactly as already described and which when operated rocks the shaft 61, and consequently the two pinions 60 and 62 thereon, the pinion in turn rocking the barrel pinion 59 oppositely and hence the shaft 57 and pinion 58 oppositely, so that the six racks will be reciprocated oppositely in sets of three, the two outside lower rollers and the upper middle roller moving together and the two outside upper rollers and the middle roller moving together and the two outside upper rollers and the middle lower roller moving together in the construe tion shown. This is exactly as the other rollers are operated although it is not an essential though an advantageous movement.

What I claim is:

1. The combination of an ink table, ink distributing rollers, slidable bearing blocks disposed in superposed order, the upper bearing blocks being supported by the lower bearing blocks, said rollers being rotatively supported by the respective bearing blocks, and means for reciprocating said bearing blocks in the direction of the longitudinal axes of the rollers and in opposite directions to each other.

2. The combination of an ink-table, ink distributing rollers, rack bars connected with the respective rollers, and oppositelyoscillatory pinions in mesh with sets of the rack bars for endwise reciprocating the same and thereby the rollers connected therewith.

4:. The combination of an ink-table, inkdistributing rollers, bearing blocks disposed in sets and having T slots the rollers having T journals to rotatively fit in said T slots, rack bars connected with the respective bearing blocks, and oppositely oscillatory pinions in mesh with sets of the rack bars, for enclwise reciprocating the same.

5. The combination of an ink-table, inkdistribi'lting rollers, rick-bars connected with the respective rollers for endwise reciprocating the same, an oscillatory shaft provided with pinions in mesh with certain of the rack-bars, a second oscillatory shaft provided with a pinion in mesh with the remainder of the rack bars and provided also with a second pinion in mesh with one of the pinions on the first mentioned shaft.

6. The combination of an ink table, a plurality of ink distributing rollers, upper and lower rack bars connected with and adapted to longitudinally reciprocate the rollers, a shaft provided with two pinions, one of which meshes with two opposite rack bars, the other pinion being wide-faced and meshing with two other opposite rack bars, and an oscillatory shaft provided with two pinions, one of which is in mesh with the remaining two opposite rack bars and the other of which is in mesh with said widefaced pinion.

In testimony whereof I allix my signature in presence of two witnesses.
