17 Claims.

This invention relates to new and useful improvements in a printing fluid distributor for printing machines.

The invention proposes to characterize the printing fluid distributor by the fact that it is composed of three rollers comprising a unit. Any number of these units may be used on a printing machine, depending upon whether or not the machine is a single color or a multi-color machine.

Specifically, the invention'proposes to characterize the three rollers of each distributor unit by the fact that one of these rollers is a rubber form in the shape of a roller upon which the rubber printing form is mounted. It is proposed that this rubber form in the shape of a. roller be engaged against a counter-pressure drum. Itis further proposed that an intaglio roller with an associated 'doctor blade be provided for supplying ink to the rubber form. The intaglio roller may be engraved, or cut in any other manner with a screen, or design, or pattern calculated to hold a predetermined quantity of printing fluid.

An inkdistributor of the type mentioned above, which makes use of an engraved intaglio roller and a doctor blade has the advantage that the printing fluid may comprise any printing fluid of any viscosity. It may be an ink, an oil, a water color, a lacquer, a varnish, a pyroxylin, a bronze, a mica, an adhesive, and other materials and colors. This wide variety of printing fluids cannot be used on the conventional four roller ink distributor which does not, contain an intaglio roller and doctor blade. In the four roller system there is a tendency for the rollers to bow and belly outwards if the printing fluid is too stiif. This is not true with the present distributor in that the doctor blade is a steel blade and works in conjunction with the engraved intaglio roller and is capable of handling any printing fluid irrespective of its viscosity.

Another and very important advantage of the present three roller ink distributor resides in the fact that it may be cleaned in a lesser period of time than the four roller system. In the first place, thereis one roller less to be cleaned. Also a metallic roller may be cleaned easier and quicker than the usual types of gelatine or rubber rollers used in the four roller systems.

The invention also contemplates arranging the printing fluid distributor in such a manner that the intaglio roller extends into a printing fluid pamand so that the doctor blade is located ber form disengage each other.

this arrangement all excess of printing fluid which is packed up by the intaglio roller will be scrapedofl by the doctor blade and will fall back into the printing fluid pan. A suitable cover may be provided for the printing fluid pan for protecting the printing fluids on the intaglio roller. This combination is superior to the four roller system in which the ink upon the first, second and third rollers has a tendency to flow to the ends of the rollers and then fly outwards due to centrifugal force.

The invention also contemplates chromium plating, or covering the intaglio roller with a suitable cover material adapted to prevent wear due to the scraping action of the doctor blade.

Another and very importantv feature of this invention resides in an arrangement whereby when one control is operated, the three rollers separate, simultaneously. It is proposed to so arrange this construction that the separation may be through a short distance so that the driving gears of the rollers remain in mesh. Or the adjustment may be through a larger distance to move the gears out of mesh. In the latter instance the rollers are free to be freely turned around for cleaning, inspection, make ready, etc. In the former instance the registration of the printing unit is not lost.

More specifically, the invention contemplates arranging the roller separating mechanism in a manner so that as the rubber form is moved out of contact with the counter-pressure roller, simultaneously the intaglio roller and the rub- This latter disengagement may be accomplished by one, or the other of the parts moving.

The invention also proposes a novel arrangement for supporting the printing fluid pan, and

for lowering the printing fluid pan so that it may be moved free from the intaglio roller when desired.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

The printing fluid distributor for printing machines, in accordance with this invention, includes a printing fluid pan l0 into which an intaglio roller ll engages. This roller II is engraved or cut with a screen. or design, or pattern to hold a predetermined quantity of printing fluid. A doctor blade I2 is provided for the intaglio roller II and is mounted within the pan I0 above the printing fluid level. A counter-pressure drum I3 is rotatively supported in standards l4 and has its axis parallel to the axis of the intaglio roller II. A rubber form l5 in the shape of a roller normally engages the intaglio roller II to receive its correct supply of printing fluid to print in cooperation with the counter-pressure drum l3. The rubber form l5 bears the printing plate or pattern. The intaglio roller H supplies said printing plate or pattern with the correct quantity of ink so that said printing plate or pattern may print.

A gear I6 is mounted upon the shaft l3 of the roller l3 and meshes with a gear I! mounted upon the shaft, l5 of the rubber form l5. This gear I! in turn meshes with a gear l8 mounted upon the shaft ll of the intaglio roller H. The gear I6 meshes with a small gear l9 mounted on a shaft which is rotatively supported in the standards l4. This shaft 20 extends from one side of the machine. The extended end of the shaft 29 is provided with a pulley 2| engaged by a drive belt 22 connected with the pinion of an electric motor or other driving source, not illustrated on the drawings.

The printing fluid pan I0 has side walls 10a which are out out to permit passage of the shaft H' which supports the intaglio roller II. The printing fluid pan I 0 is also provided with a cover 24 which is connected by hinges 25 with the rear edge of the pan l0. handle 26 by which it may be conveniently gripped so that the cover may be pivoted open and closed. The cover 24 partially extends over the top of the intaglio roller l I.

The doctor blade l2 comprises a steel blade l2a which is sandwiched in between a top strip 21 and a bottom strip 28, see Fig. 3. These strips are secured together with screws 29. The ends of the strips 21 and 28 engage in between support strips 30 mounted upon the inside faces of the end walls of the pan I ll. These support strips 30 are arranged along the bottom, the top, and the back of the doctor blade. The doctor blade l2 may be removed by moving it frontwards. However, this frontward motion is not This cover has a possible until such time that the pan I0 is lowered to be free from the intaglio roller II.

A plate 32 is rigidly secured to each end of the bottom wall of the printing fluid pan l0. These plates extend laterally and rest upon holders which include support strips 33. Each support strip 33 has an overhanging rear strip 34 (see Fig. 1) which engage over edge portions of the plates 32 to hold the rear ends of the plates from moving upwards. The strips 33 are attached to brackets 35, see Fig. 5, which are adjustably mounted horizontally on vertical slides 36. Each slide 36 has a pair of front and rear lateral arms 36a. A rod 31 is fixedly mounted between these arms 36a by cap screws 38 engaging through the arms 36a and into the rod 31. The brackets 35 are slidably mounted on the rods 31. Each bracket 35 has a lateral lug 35a which are threadedly engaged by screws 39. These screws 39 have bearing portions 390 rotatively mounted in the front arms 36a. The outer ends of the screws 39 have knurled heads 39b which may be manually turned.

When the screws 39 are turned the bracket 35 will be caused to move rearwards or forwards and will correspondingly move the strips 33, rearwards and forwards, so that the pan I0 is moved rearwards and forwards. This is an indirect control for engaging the blade l2a of the doctor blade l2 against the intaglio roller ll. under desired pressures.

Each slide 36 is vertically slidably mounted in a wall member 40. These wall members are formed with vertical slots 4| through which portions 36b of the slides 36 pass. A strip 42 is attached on the extended ends of each of the portions 36b. These strips 42 extend into recesses 43' formed along the edges of the openings 4|. Holding strips 44 are secured upon the wall members 40 and extend over the edges of the strips 42. Thus the strips 42 are vertically slidably supported and consequently the slides 36 are correspondingly supported.

A stud 45 projects from each slide portion 36b. A link 46 is pivotally mounted on each stud 45 and extends downwards and pivotally connects with the rear ends of levers 41. These levers 41 are fixedly mounted upon the ends of a shaft 48, see Fig. 9, extending from side to side of the machine. One of the levers. 41 has a forward extending portion 41a provided with an upwardly extending handle 49 by which the shaft 48 may be manually turned. This forward extending portion 41a is provided with a pintle 50 extending through from one side to the other. The outer side of the pintle 50 is provided with a collar 5| through a rod 52 passes. This rod 52 has heads 53 at its ends which prevent the rod from coming out of the collar. The inner end of the pin 50 supports an arm 54 which extends rearwards and normally engages against one of the tracks 44 and rests on a support pin 54a for holding the levers 41 in the positions illustrated on the drawings. The arrangement is such that the pin 52 may be turned to rotate the arm 54 anti-clockwise, freeing it from the pin. 54a and track 44 and then the handle 49 may be let rearwards so that the shaft 48 turns clockwise with specific reference to Fig. 1, and the rear ends of the levers 41 move downwards, indirectly lowering the printing fluid pan III. The cover 24 must be pivoted to an open position before this is done so that the pan I0 is free to move downwards.

Each wall member 40 is provided with a bottom flange 40a slidably engaged in a groove 56 formed i in the top of a forwardly and rearwardly extending channel member 51. Strips '58 are mounted along the edges of the grooves 58 to slidably lock the flanges 48a upon the channel members 51. The channel members 51 are supported upon the frame 58 of the, printing fluid distributor and the printing machine. The standards |4 comprise a pair of side walls having bottom'flanges 88 which are mounted on recessed areas 51a of the channel members 51.

A bracket 82 is fixedly mounted on the front end of each channel member 51. Each bracket 82 has a forked upper end supporting a turnable stud 83. A screw 84 threadedly engages through each stud 83. The front end of each screw 84 is provided with a handle 85. The rear end of each screw 64 rotatively engages through the rear end of a horizontal arm 88. Each horizontal arm 88 has an upwardly directed rear end 88a through which the screws 84 pass. and 88 are mounted upon the screws 84 to the rear and front of the ends 88a for accomplishing the rotative connections between the screws 84 and the horizontal arms 88.

The front end of each horizontal arm 88 is formed with a circular opening 18 in which cylindrical eccentrics 1| are mounted. However, the eccentrics 1| are formed with openings 13 which are off center. A hollow shaft 14 is coaxially arranged about the shaft 48 and has its ends extending into the opening 13. Pins 15 rigidly connect the eccentrics 1| upon the end portions of the shaft 14. Fig. 9 clearly discloses the eccentricity of each eccentric 1|. This eccentricity is also shown in dotted lines in Fig. 8.

The hollow shaft 14 passes through openings 18 in the wall members 48. Immediately adjacent the inside faces of the wall members 48, and mounted upon the hollow shaft 14, there are additional cylindrical eccentrics 11. These eccentrics 11 are pinned to the shaft 14 by pins 18. The-eccentrics 11 are identical to the eccentrics 1| except for the fact that they are set 90 apart. The eccentrics 11 have their thick portions directed towards the rear of the machine, and the eccentrics 1| have their thick portions at the top. This is clearly shown in Fig. 8.

A pair of vertical arms 88 are disposed immediately adjacent the inner faces of the wall members 48 and have circular openings 8| into which the eccentrics 11 engage. These eccentrics 11 have off center openings 82 through which the hollow shaft 14 passes. As before stated, the

pins 18 connect the eccentrics 11 with the hollow U shaft 14. Vertical screws 8| are rotatively mounted onthe upper ends of the vertical arms 88. The lower ends of the screws 8| pass through offset ends 88a of the vertical arms 88. Collars 82 and 83 are mounted on each of the screws 8|, above and below the offset portions 881; and accomplish the rotative supporting of the screws 8|. The upper ends of the screws 8| are provided with handles 84 by which they may be turned. A handle |85 is mounted on the hollow shaft 14.

Each screw 8| passes through the forked end 85a of a horizontal lever 85. Specifically, each screw 8| threadedly engages a stud 86 which is rotatively supported in the forked end 85a of each lever. Each lever 85 is pivotally supported intermediate of its ends by a pintle 81 supported on the adjacent wall member 48. The rear ends of the lever 85 are provided with bearing blocks 88. These bearings rotatively support the shaft C'ollars 81 l5. The rubber form l5 in the shape of a roller is fixedly mounted on the shaft l5 by several holding elements 88. This form I5 comprises solid end discs |5a across which a hollow roller |5b is mounted. Rubber form plates 82 are adhesively mounted on the roller |5b. These rubber form plates are generally known in the art and further details will not be given in this specification. The outer surface of the rubber material 82 contains the printing form. The inner surface is provided with adhesive material by which the form 92 is adhesively mounted on the roller l5.

The shaft l5 has reduced ends 88a which are rotatively supported by ball bearings 88 suitably mounted on the-bearing blocks 88. Specifically, the bearings 83 have inner races 83a mounted on the shaft ends 88a. These inner races are held in position by tubular members 84 which are engaged on the reduced ends 88a. Washers 85 and cap screws 88 are mounted upon the ends 88a and engage the ends of the tubular members 84 for holding these parts in position. The ball bearings 83 have outer races 83b which are held in position by inner bushings 81 which are mounted on outer bushings 88. These outer bushings 88 are mounted on the bearing blocks 88.

One of the bushings 88 is adjustably supported. There is a screw 88 threadedly engaging the material of one of the levers 85 and this screw has a bearing portion 88a engaging a groove I88 formed in lug portions |8| projecting from the periphery of the flange of the outer bushing 88. The screw 88 has a large outer head88b by which it may be turned. Turning of the screw 88 causes the bushings 91 and 88 to move laterally inwards or outwards, and this motion is indirectly communicated to the shaft l5 and hence the roller l5. This construction permits a lateral adjustment of the roller I5 which is necessary to register the form roller in the printing operation.

The operation of the device is as follows:

The screws 84 may be turned so that they move forwards or rearwards on the studs 83 and similarly move the horizontal arms 88. The forward and rearward motion of the arms 88 is communicated by the hollow shaft 14 to the wall members 48 and thus the wall members 48 may be moved rearwards and forwards on the channel shaped members 51. Since the form I5 is indirectly mounted on the wall members 48 by the levers 85 and the pintles 81,*the form l5 will move forwards and rearwards and in this manner a satisfactory printing pressure may be obtained between the form l5 and the counter-pressure drum IS.

The screws 8| may be turned in one direction or the other to cause the studs 88 to move upwards or downwards, and this motion is indirectly transmitted by levers 85 to the form I5 to engage the form' l5 against the intaglio roller II. In this way a suitable pressure may be obtained between these rollers.

The handle I85 may be moved to turn the hollow shaft 14. This causes the turning of the two eccentrics 1| and the two eccentrics 11. The eccentrics 1| will rotate in the two horizontal arms 88 and since these arms cannotmove forwards or rearwards, the shaft 14 will move instead. However, the arms 88 may pivot upwards and downwards because of the studs 83 which 'are tu'rnably mounted in the forked ends 82a of the brackets 82. The hande |85 may be turned in a direction (clockwise in Fig. 8) so as to cause the shaft 14 to move towards the front (towards the left) of the machine. This will move the wall members 40 correspondingly and cause the indirect disengagement of the form I5 from the counter-pressure drum I3.

The handle I05 may be moved through but a small distance so as to separate the form I5 from the counter-pressure roller I3 a small distance so as not to cause the complete disengagement of the teeth of the gears I6 and I1. Thus the registration of the printing unit is not lost. However, if desired the handle I05 may be turned sufficiently to cause the teeth of these gears I6 and I I to disengage, and then the form I5 and the drum I8 are free to be selectively rotated.

Simultaneous with the operation of the eccentrics 'II the eccentrics II also function. However, these eccentrics I! operate to lower the vertical arms 80. The vertical arms 80 are capable of pivoting on the studs 85 which are supported by the levers 85. As the vertical arms 80 move downwards the front ends of the levers 85 will be moved downwards and the rear ends of these levers will move upwards causing a separation between the intaglio roller Ii and the form I5. Here again this separation may be slight so that the teeth of the gears I1 and I8 stay in mesh, or if the handle I05 is turned through a sufficient distance the teeth will disengage each other, freeing these rollers completely.

Attention is called to the fact that when the handle I05 is operated, the form I5 is moved out of, or into contact with the counter pressure drum I3, and: simultaneously the form I5 in the shape of a roller is moved into, or out of contact with the intaglio roller II. It should be noted that the screws 54 and 8I are not disturbed and therefore the adjustments of these screws and the corresponding pressure set of the rollers, which these screws control, remain the same.

When desired the ink pan I0 may be lowered by first moving the cover 24 forwards and then manipulating the handle 49. The handle 48 is first moved slightly forwards to free the arm 54 which may be pivoted counterclockwise by suitably turning the pin 52. Then the handle 49 may be permitted to move rearwards. Since the handle 49 is connected with one of the levers 41 which is mounted on the shaft 48, which in turn is connected with the other lever 41, the levers 41 will move downwards and so the ink pan I0 is lowered. The ink pan I0 comes to rest when the strips 42 strike the bottoms of the grooves 43.

The ink pan I0 is now free and may be removed. First the front end is lifted upwards and then the ink pan is moved frontwise to disengage the plates 32 from beneath the forwardly offset strips 34.

When the apparatus is in the condition illustrated in Fig. 1 the knobs 39b of the screws 39 may be turned in one direction, or the other to cause the ink pan I0 to move forwards or rearwards and so indirectly control the pressure of the doctor blade I! against the intaglio roller II.

Attention is called to the fact that the doctor blade I2 is completely encased within the ink pan I 0 and consequently there will be no splashing or flying of printing fluid during the operation of the doctor blade on the intaglio roller. All fluid which is stripped oiT the surface of the intaglio roller will drop back into the printing fluid pan.

An important feature of the printing fluid distributor resides in the fact that the doctor blade I2 is capable of stripping printing fluids of various viscosities from the intaglio roller II. The rubber form I5 is capable of picking out the printing fluid which remains in the recessed portions of the intaglio roller II. In this way the printing fluid is simply and efliciently applied to the rubber form I 5. The rubber form I5 then prints directly on web material passing between it and the counter pressure drum I3. Attention is called to the fact that the intaglio roller receives a new supply of printing fluid on each rotation. More detailed advantages of this three roller system have been described in the objects of the invention.

The rubber form I5 may readily be removed by removing the bearing blocks 88. This form I5 in the shape of a roller may be replaced with similar forms of diiferent diameters, of course, within certain limits depending upon the range of adjustment of the screws 64 and BI, and the levers 85.

In Figs. 10-12 inclusive, a modifled form of the invention has been disclosed which distinguishes from the prior form in the fact that the rubber form I5 may be removed and replaced with a similar form of a different diameter, and yet the point of contact I5a: of this form I5 on the counter-pressure drum I8 will not vary for the different sized rollers. In the prior form because the rubber form I5 is supported by the pivotally mounted levers 85 its point of contact on the counter-pressure drum I3 will vary in accordance with different diameters.

In this form of the invention the rubber form I5 is rotatively supported on the rear ends of rear lever members 85y. These rear lever members 8511 are adjustably mounted on levers 851: which are pivotally supported intermediate of their ends by the pintles 81 on the wall members 401:. These wall members correspond with the wall members 40 in the prior form of the invention. The means for rotatively mounting of the rubber form I5 on the rear lever members 85;! is identical to the corresponding means for rotatively mounting the form I5 on the levers 85 in the prior form of the invention, and identical parts may be recognized by like reference numerals.

The levers 85:: are formed with grooves I06 on their inner sides. Rails I01 are mounted along these grooves to form a track construction. The front ends of the rear lever members 8511 are formed with follower elements 85yy engaging these tracks, in a manner so that the rear lever members 85y may be moved forwards and rearwards. A screw 81a: is rotatively connected with each rear lever member 85y. These screws 8I2: threadedly engage through lugs I08 mounted upon the front ends of the levers 851:. The outer ends of the screws 8Ix are provided with handles I09 by which they may be turned. The inner ends of the screws 8Ia: have head portions IIO rotatively engaged in complementary recesses formed in the front ends of the rear lever members 851/ to accomplish the rotative connection of these parts.

Vertical arms 80x are pivotally connected by pintles IIO to lugs III on the front ends of the levers 851:. These vertical arms 80:: extend downwards and have their bottom ends formed with circular openings engaged by eccentrics, not shown in the drawing, but corresponding identically to the circular openings 8| and the eccen- 80:): of this form of the invention correspond with the vertical arms 80 of the prior form. In other respects this form of the invention is similar to the prior form and like parts may be identified by like reference numerals.

The operation of this form of the invention is as follows:

The screws Illa: may be turned in one direc tion or the other to control the set" pressure between the intaglio roller II and the rubber form l5. When the screws 8h: are turned the rear lever members 85 move forwards or rearwards for accomplishing the pressure control.

When the handle I05 is manipulated, as described rel-ative to the preferred form of the invention, the eccentrics 11 will draw the vertical arms 80:: downwards to pivot the levers 85a: and the rear lever members 851 to disengage the rubber form l5 from the intaglio roller I I. Simultaneously, the eccentrics II (referred to in the previous form of the invention) will rotate inthe horizontal arms 66 to move the wall members 40a: frontwise and so simultaneously disengage the contact between the rubber form [5 and the counter-pressure drum IS.

A feature of this form of the invention resides in the fact that the rubber form l5 may be replaced with similar forms of different diameters. Yet each of these forms will contact the identical point I33: on the counter-pressure drum l3.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
