20 Claims. (Cl. 101-365) This inventinrelates to apparatus for adjusting' the scraper blades of ink supply mechanism for printing presses, and has for its object broadly the provision of means whereby the operator of the press may effect an adjustment of a substantial sectional portion of the blade more quickly than has been possible in the past.

In the printing of large metropolitan newspapers pages are often changed from one edition to another, and, inasmuch as certain pages require more ink than others, due to the nature of the matter printed thereon, it frequently becomes necessary to make a complete adjustment for a one-page wide section of the blade. In accordance with the present practice, the operator is required to adjust eight or more screws to make an adjustment for an eight column page, and this takes considerable time as well as being inconvenient and laborious. My invention dispenses with the necessity of this slow and tedious adjustment by providing convenient and effective means whereby a sectionof the blade corresponding to one page of the paper may be adjusted by a single operation, such for example, as the manipulation of a conveniently located handwheel.

With this and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

Fig. '7 is an elevational view, partly broken away, of a modified form of the actuating mechanism for the apparatus adapted for either local or remote control; and

Fig. 8 is a plan view, partly in section, of the mechanism shown in Fig. 7.

Upon said drawings, which illustrate a preferred embodiment of the invention, the reference numeral ll indicates an ink fountain which may be of the type customarily used in newspaper printing presses. A roller I2 is mounted for rotation in said fountain, being carried upon a shaft l3 extending lengthwise of the fountain near one side thereof, said roller, when the press is operating, being partly submerged in the ink l4 contained in the fountain, as shown in Fig. 1 of the drawings. A blade I5 is positioned to engage the surface of the roller l2 to remove a part of the ink therefrom as the roller rotates in counter-clockwise direction (viewing Fig. 1), said blade in the present instance being sectional and each section thereof being mounted on the underside of one of a plurality of brackets I6, to which it is attached by means of screws I1 and a clamp bar I8, it being understood that there is one of said brackets l6 for each section of the blade. The point of attachment of the blade sections is near the rear edge thereof and they are made of springy or resilient material, such as spring steel to permit adjustment thereof relative to their supporting brackets and also to provide a yielding contact with the fountain roller in the well-known manner. I

The brackets I6 are mounted on a longitudinal shaft l9, which is carried in fixed supports 2| exis held against rotation by means of screws 23 as clearly shown in Figs. 3 and 4. The brackets I6 and associated parts are adapted to be rocked about thisshaft as independent units to effect a collective adjustment of particular blade sections, as will hereinafter appear.

A plurality of pairs of uprights 24 extend upwardly from the fixed bracket 22 and are formed to provide bearings 25 at their upper ends for a shaft 26 extending lengthwise of the assembly. The left hand pair of uprights 24 (viewing Figs. 2 and 3) have forwardly extending portions 21 providing bearings for a second shaft identified by the reference numeral 28, which shaft, however,

is of shorter length than the shaft 26,.extending merely between said bearings 21 and to the left thereof into a bearing 29 carried by a bracket 3| supported upon the fixed bracket or brace 22 at the left end ,of the latter.

An eccentric 32 (shown in Figs. 4 and 6) is mounted on the shaft 26 between the bearings 25, shown at the right in Figs. 2 and 3, being secured to said shaft by means of a pin 33. A sleeve 34, having an eccentric bore 35, is positioned upon said eccentric and is provided with arms 38 extending forwardly and connected at their outer ends by a shaft 31, to which one of said arms is fixedly secured by a set screw 38. Similar parts, which are correspondingly numbered, are

. mounted on the shaft 28 between the bearings 21, and will not be separately described.

Said shaft 31 also extends through a bore 38 in a-cylindrical part 4| of a lug 42 extending upwardly from the movable bracket l6 at the right of Fig. 3, and the bracket at the left of said Fig. 3 is similarly connected to the arms 36 shown at the left of the figure.

The regular adjusting screws 43, one of which is shown in Fig. 4, are mounted in the brackets l6 with which they have a screw thread connection as indicated at 44, the upper end of each screw having a worm wheel 45 in mesh with a worm 46 carried on a diagonal, horizontal rod 41, there being a numberof said rods and worms corresponding to the number of said adjusting screws, several of the rods being shown at the left center of Fig. 3 of the drawings. The worms are held in engagement with the worm wheels by means of straps or keepers 48 in the usual manner, and cover plates 49 are provided over said individual adjusting devices, each said plate having a flange 5| secured to the associated bracket [6 by means of screws 52, it being understood of course that there is one of said cover plates 49 for each of the movable brackets I6.

The rods 41 protrude through parallel plates 53 and 54, shown at the left of Fig. 3, the outer ends of said rods being provided with square heads 55 adapted to be engaged by a wrench for individual adjustment of the screws 43 in manner which is well-known in the art. The screws 43 are normally positioned so that the adjustment of one thereof adjusts a section of the blade I5 corresponding in length to the width of a newspaper column, and, in the use of the apparatus of my invention, this adjustment is effected in the same manner that it has heretofore been done, there being sufiicient flexibility in the rods and enough play in the connections between the parts to permit the collective or page adjustment hereinafter described.

For the purpose of effecting said collective or page adjustment, I provide means for rotating the shafts 28 and 26, which means may be operated by hand, and, if desired, also by electric control from a remote point as will later appear from the description of Figs. 7 and 8. For purposes of hand operation I provide handwheels 56 and 51 mounted respectively on shafts 58 and 59 extending through bearings 6| and 62 formed in the bracket 3|, as clearly shown in Fig. 3. The shaft 58 carries at its inner end a worm 63 meshing with a worm wheel 64 carried at the outer end of the shaft 28 and the shaft 58 carries a similar worm 65 which is in mesh with a worm wheel 66 on the end of the shaft 26. The worms and worm wheels provide a positive connection between the hand wheels 56 and 51 and the shafts 28 and 26, respectively, and serve to hold said.shafts and the parts carriedthereby in their adjusted positions.

Referring now to Figs. 3 and 4, it will be noted that rotation of the shaft 26 by operation of the hand wheel 51 will cause the eccentric 32 carried on said shaft between the bearings 25 to move correspondingly, and rotation of said eccentric in the bore 35 of the sleeve 34 will move said sleeve bodily either to the right or to the left (viewing Fig. 4) in accordance with the direction of ro tation. Inasmuch as said sleeve is connected by the arms 36 with the shaft 31, the latter will be moved. correspondingly and, through the lug 42,

will rock the bracket l6 about the shaft I9 in manner which will be apparent from the foregoing description. When said bracket is rocked in counterclockwise direction (viewing Fig. 4), it will obviously move the blade section l5 carried thereby into closer engagement with the fountain roller I2, and this will be accomplished without disturbing the adjustment, of the screws 43 with respect to said blade section, since said screws are carried by the bracket l6 and remain in contact with the blade irrespective of the adjusted position of said bracket. Rotation of the bracket in clockwise direction of course will relieve the tension of the blade section l5 against the fountain roller l2, thus permitting a greater amount of ink to be delivered by said roller to the ink-motion of the press. If a column adjustment should be desired without changing the adjustment for the entire page, the appropriate screw 43 may be adjusted through the proper rod 41 in the usual manner. Thus the capacity of the apparatus for adjusting the blade for individual columns is not affected in any way by the construction which I employ, but provision is made for saving a great deal of time and effort by adjusting an entire blade section at one time when the occasion requires.

It will be understood of course that when it is desired to operate the full-page adjusting mechanism shown at the left of Fig. 3, this may be done by operating the hand wheel 56 and associated parts in the same manner as has been described with reference to the parts operated by rotation of the hand wheel 51; also that two additional page-wide units will normally be provided, in the case of a standard newspaper press, at the right of, and as a continuation of the mechanism shown in Figs. 2 and 3, the hand wheels for operation thereof being preferably positioned at the opposite end of the fountain, and the,

individual adjusting devices will also be duplicated for the right half of the apparatus.

While the eccentrics 32 provide an emcient means for effecting the collective adjustment, as hereinbefore described, and serve to produce a powerful leverage through the exercise of relatively slight force in the operation of the hand wheels 56 and 51, it will be evident that other means, such as screws or equivalent motiontranslating devices, could be employed inplace of the eccentrics if desired.

Referring now to Figs. 7 and 8, it will be observed that I have made provision for operating the collective adjustment devices electrically, thus making it possible to control the operation from a remote point by means of suitable push buttons or switches, as will be readily understood. As shown in these figures, worm wheels 61 and 68 are loosely mounted on the- shafts 58 and 59, respectively, the worm wheel 61 being in mesh with a worm 68 carried upon the upper end of an armature shaft 1| extending upwardly from a vertically positioned motor 12 suitably supported on the frame, and the worm wheel 68 is likewise adapted to be driven by a worm 13 on the upper end of an armature shaft 14 of a motor 15 similarly supported from the frame. The wiring for connecting the motors 12 and 15 with suitable sources of electric current, and the circuit controllers for energizing and deenergizing the motors, are not shown, since such devices are well-known and a suitable arrangement for this purpose would be obvious to anyone skilled in the art. I

The hand wheels 66 and 6'! have inwardly extending hub portions 16 and I1 terminating in clutch elements 18 and I6 adapted to engage complementary elements 6| and 62 which are integral, respectively, with the worm wheels 61 and 66. Said hub portions of the hand wheels are connected to the shafts 66 and 69 by means of keys 83. Springs 64 and 66 are provided on the shafts 58 and 69, respectively, and tend to hold the clutches normally engaged, as shown at the left in Fig. 8, said springs being positioned between the outer ends of the hubs I6 and I1 and collars 66 secured to the outer ends of the shafts. With the clutch thus engaged, rotation of the worm wheel 61 will rotate the shaft .68 through the hub 16 and key 83 in manner which will be evident from an inspection of said Fig. 8. When it is desired to operate one of the hand wheels by hand, it may be pulled outwardly, as shown at the right of Fig. 8, from which it will be seen that the-clutch I9, 82 is disengaged so that the shaft 59 may be rotated through the connection of the hub ll with said shaft by means of the key 83, the spring at this time being compressed between the outer end of .said hub 11 and the collar 86 on the outer end of said shaft 59. With this arrangement the collective adjustment devices may be operated by hand or by electric control at the will of the operator, it being evident, however, that the remote control feature can be omitted if it should not be considered necessary or desirable in particular installations.

It is thought. that the invention and many of its attendant advantages will be understood from' the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
