I shall first describe enough of the press on'which my ink distributor is usedto .illustrate thea-pplication of my distributor.

Thel press frame is indicatedV at 10. 'Slidably supported on the press is a second frame 12, which is adapted to carry the chase 14. The frame 12 and chase 14 reciprocate horif zontally. v

yAt one end of thepressis an inlring fountain, comprising an inclined ink plate-16 adjacent to the lower edge of which rollsthe large ink roller-18. j

Arranged above'the path of travel of the chase 14 are the ink distributing rollers indicated generally at A. The right-hand roller of the series Aindicatedlat20 is inclined from the4 true transverseline as shown in Figure 1. y v r I The* press has rollers 22 on which the frame 12 rolls or travelsfor bringingthe .chaseY 14 and the type or cuts or 'the like 14 therein underneath the inking rollers B. v .Y j `l The frame 12 carries the inlring plate I A transverse shaft 28 is mounted 'in the frame and has at its ends the armsBO which supf port the roller 32. l Y Y On the` shaft 28 is anarm 34to which is connected an actuating rod or the like 36.

1n the operation of the press', `the frame, 12 moves to the'left and while it is making the left-'ward portion of its movement, the rod' 86 isaotuated for moving the arm 34 for rock Ing the shaft 28 andniovingthe roller 32 from its position shownin Figure 2 doWn-' wardly until the roller32` contacts with the large roller 18. Y l The roller 18 is rotated v,by mechanism not here particularly shown.

Then `when theframe 12 A withy the `roller 18'for a suiicient time to take up a supmoves to the'l right, the inkv on the roller 32 A is distributed over the ink plate 26.

It is 'mypurpose to insure the distribution ioo of thisfheavy'line and otherstreals of ink,

vprising* a distributor roller 38 having For accomplishing this purpose, I have mounted an auxiliary ink distributor, comthe metal shaft.. 40 projecting from itsends. At

one end, the shaft 40 is journaled adjacent to theroller 20 in the following manner:

On the frame 10 is mounted a support 42 having on its upper end a threaded portion 44. kA threaded socket is adjustably screwed onto the portion 44 and projects up- WardlvV therefrom. In the upper end of the socket 45 is a spindle member 47 termi natingin a yoke 49.

lOne'endof the shaft 40 is slidably extended through. the yoke 49 and held in position by a'key 51,'assh-own in Figure 4. .Thus the roller is mounted at the end now under consideration foruniversalA movement, andthe shaft 40 lcan rotate' or slide in the yoke 49.

ranged boss 56.

y vice is applied.

The'roller can be adjusted vertically byv Abel crank isrjournaled on the spindle 58 and its upper end is provided with a threaded socket 62. 4Screwed into the socket 62 is a rod 46. (See Figures 3 and 6.)

i At the upper endof the rod 46 now under consideration isV ahalf socket 48which coacts with a half socket 5()v (see Figure 6.) Re` ceived in the socket members 48 and 50 last i"4 vdescribed isa ball 52d.' `rlhe'half sockets are 'secured together by screws 43.

" ,i One end ofthe shaft 40ise`Xtended through the ball* 52d andvis lockedthereto -by means of .a screw 64.-

`'lhe'bell crank has a vdownwardly extending arm 66 `having an'elongated slot 68 (see Figure 2.)

`Fixed to the endofthe shaft 28 and preferably projecting outwardlytherefrom is an arm 7 0 having a plurality of threaded openings 72 (see Figures 2'and 4.) Y

The' arms 66 and 70 are connected Vby a twofpart link consisting of the socket memv ber."74, which is pivoted to the arm 70 by means of a shouldered screw or the like 7 6,`

having threaded into it`one endof a short rod 7 8'. Extended through the rod T8-,is a Fibolt or the ylike 80, which can freelyV rotate .in the rod 78l (see Figure 5.)

' On the bolt 80, which thusserves aS 2L Pin' tlejisan annular flange orshoulder 82. The other yend of thei'bolt 8O is extended through `the lar1n166` and has a nut 86, bywhich the arm 66 can be frictionally gripped against the shoulder 82 for lockingl the rod 78 to Y, the arm 66 at'any position in the length of the slot 68. Y

vI shall now explain the actuation of the roller 38. p "i vVhen the roller 32 is swung to its lowermost position asshown in Figure 2, the roller 38 will be Aswung; to its left-hand position illustrated for instance in full lines in Figure l. v

VVhenthe roller 32 isl swung back to its Y upper position` shown in Figure 3, the opera tion of the parts is such that the roller 38 is swung fromitsfp'osition shown in Figure l to its position shown in dotted lines in that figure, ywhere it contacts withthe roller 32,V so that as the roller 32 is` rotated by the movement of the plate 26] thereunder, the roller 38 will also be rotated'byrthe Vroller 32. In the full line position, the roller 38 l will be rotated-by the roller 20.` I

rIhe contact of the roller 38-with vthe roller 32 will help to smooth out anddistribute the ink on the roller 32. I l

When the roller38 is inits'position shownV in Figure l, it will contact with.Y the roller 20. The roller 2O is rotated by mechanism not here shown, and while it is'y in contact with the V*roller 38, theroller 38will-help to smooth out and distribute any heavy ink streak on the roller 20. j L Y Thus when the roller 38'is in one position, it contacts with aroller extending in a proper transverse line across the press, and when Ait is in its other position shown by full lines in Figure l, it will be inclined v'from the transverse, and will be parallel with and 'Contact ing with the roller 20. Y i

On accountof'the peculiar. mounting ofy the end of the roller 38 sho-wn at the righthand part ofv Figure 4, the left-hand lof the roller may swingon themeinber 58 as a ccnter without any binding of any ofthe parts. I find that in actual use, the. use of the roller 38 servesv to produce a much more even llO and complete distribution of the ink, lthan is possible without it, and that ythe streaks vwhich are Otherwiseleft arealmost-entirely eliminated. Particularly in this respect, attention is called to the fact that when the roller 32 is in contact withthe fountainroller 18 and the two are rotated, a little ridge or body'of ink f is formed along their line of engagement;

When the roller 32 is swung from its position show n in Figure 2 towardits position shown 1n Figure 3, it carries a ridgevor thickened linev of ink, which'where myinventionis not i used, is deposited on Ythe 'plate 26 and is neyler entirely eliminated by the distributing ro ers. f

n'wiube noted that ramoner es is of a.

diameter different than that of .the roller 32. 1' It is therefore obviousithat when the rollers 32 and 38 are in their positions shownin Figure 3, this heavy or thickened line of ink will be deposited on the roller 38 and back again at several new places on the roller 32. This is assuming that the roller 38 is of smaller diameter than the roller 32. Consequently there will bea considerable distribution and smoothing out of this thickened line as it is being transferred to the plate 26. When the roller 38 moves over to engagement with the roller 20, the thickened line or lines which will have been deposited on the roller 38 will be deposited in several lines, on the roller 20, and this further contributes to the ultimate even distribution of the ink.

In actual practice, where my auxiliary distributor is not used, I find that the roller 32 tends to distribute the thickened line on the plate 26 atthe same place by successive operations, so that the unevenness in the distribution of the ink is increased the longer the press runs. This is due to the periodic operations of the press, which have the effect of timing the roller 32.

It will, of course, be understood that some changes may be made in the details, of the construction and arrangement of my ink distributor without departing` from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modied forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.-

I claim as my invention:

l. In a press having a plurality of distributing rollers, including one roller arranged at an angle to the transverse and havinga swinging inking roller, an auxiliary distributing roller mounted at one end for universal and for rotary and limited sliding` movement, means for moving the other end of said auxiliary roller for causing it in one position of its movement to contact with said inclined distributing roller in substantial parallelism therewith and in another position of its movement to contact with said swinging roller in parallelism therewith.

2. In a device of the class described, the

combination of a press structure having an ink distributing roller inclined from they transverse and an ink roller mounted to ,swing from one position to another with an auxiliary roller of a diameter different from that of the ink roller, means for actuating said auxiliary roller for bringing it into lengthwise contact with said inclined roller and holding it there for a limited time land then moving the auxiliary roller to position for contacting with said swinging roller in one position of the swinging roller and holding the auxiliary roller in such contact for 'a limited time.

4. lIn aI device of the class described, the combination of a press structure having an ink distributing roller inclined from the transverse and an inkroller mounted 'to v swing from one position to another with an auxiliary roller, means for actuating said auxiliary `roller `for bringing it into lengthwise contact with said inclined roller and holding it therefor a limited time and then moving the auxiliary roller to position lfor HENRYVW.
