- 11 Claims. (Ol. 101-352) The principal objects of this invention are to provide means whereby the ink motion carriage can be moved readily in or out of printing position by merely moving a lever or using a button and to provide a power driven means for the ink motion, operative when the ink motion is out of contact with the printing cylinder.

Other objects and advantages of the invention will appear hereinafter.

On printing presses arranged with the ink motion mounted in a carriage for the purpose of removing it from the printing cylinder, it is customary to ml the carriage back by hand power.

This is usually done by turning a hand wheel mounted at the side of the carriage, or, in some cases, a long ratchet lever is used instead of the hand wheel.- Locking mechanisms of different kinds must also be released before the carriage can be moved. This method is bothersome, un-

handy and too slow as ink carriages must be moved very often, as for instance, when plating, adjusting, inspecting, and cleaning the plates on the printing cylinder.

It is also customary with these presses to provide some means for revolving the ink motion while the carriage is out of contact with the printing cylinder. The purpose of this is to ink up the motion and be ready for printing assoon as the carriage is moved against the printing cyl inder so as not to waste paper. This is also clonev by hand power up to date. The invention is shown in connection with a printing couple comprising a printing cylinder 2 and an impression cylinder 0. 5

The ink carriage I is held in place at one end 5 by a block 9 which is adjustably mounted on a rail 4. The rail 4 is secured to the frame I of the press. The carriage is prevented from movin back by spring-seated dogs 5 and 5a, each of 10 which stops against the cam shaped end of a stop block 9. This block 6 is adjustabiy mounted on the side of the rail 4.

At the center of the frame I is mounted a vertical drive shaft I. This shaft may be driven 16 by a separate motor drive. It may connect with a plurality of ink motions. 'Ihrough mitre gears 9 and Ill this shaft 9 drives a shaft II. On the shaft II are mounted spiral gears l2 and it free to rotate. place by a head and collar connection with a bracket l4 fastened to the side of the carriage l.

The inside faces of the gears l2 and I3 have clutch jaws which match those of a double throw clutch l5 splined to the shaft ii. The 25 spiral gear l2 meshes with a spiral gear l6 which is keyed to a pinion shaft I'I, thereby driving it. This shaft l1 extends across the press and is supported by the ink motion carriage I. Immediately inside the rail 4, on both sides of the press, are mounted racks l9 and I8. These mesh with pinions l9 and I9 which are keyed to the shaft I'I. Therefore, the racks are engaged equally and simultaneously by this construction.

The spiral gear l3, which is of the same hand 35 as the spiral gear l2, meshes with a spiral gear 20. On the hub of the spiral gear 20 is keyed a gear 2| which meshes with a spur gear 22. The spur gear 22 is keyed to the spiral gear I 6. The spiral gears I6 and 20 are'far enough apart so 40 as not to interfere with each other.

The clutch I5 is operated by a lever 23 pivoted on the bracket I4 and connected to an operating lever 24 by a connecting link 25. The operating lever 24 is loosely fitted on a shaft 26 and 45 held in place by a washer 26 and screw 26 A knob 5 on the dog 5 interferes with a. projection 24 on the lever 24.

When the carriage is to be moved, the shafts 8 and II are rotating from any source of power, 50

not shown. The operating lever 24 is'pushed to the left, as shown in Fig. 1, thereby raising the dogs 5 and 5. By the time these dogs are all released, a stud 21 on the operating lever 24 has reached the end of a slot 25 in the connection 56 Each of these gears is kept in go until the clutch i3 engages with the jaw face.

on' the spiral gear II. This gear l2, because of its meshing with the spiral gear l3, will therefore turn the shaft i1.

Since the pinions II and i3", which are keyed to the shaft l1, engage with the racks l3 and II", which are fastened to the rails 4 and 4', it will be understood readily that the ink motion carriage will move backward when the shaft l1 revolves. Unless the operating lever 24 is pulled to the right so as to release the clutch from the spiral gear II, the ink carriage will continue moving until the lever 23 strikes a limit stop 33 mounted on the rail 4. This automatically releases the clutch and stops the travel.

The operation for bringing the carriage toward the printing cylinder will now be readily understood. The lever 24 will be pushed to the right until the clutch ll engages the spiral gear N. This gear, being of the same hand as the gear I! but driving the shaft i1 through an intermediate 3i, will turn the shaft l1 in the opposite direction. This causes the carriage i to move toward the printing cylinder until the lever 33 strikes against a limit stop 23, mounted on the rail 4, which releases the clutch. The dogs 3 and 3" will, at this point, drop into looking position actuated by a spring 33, which tends to turn the shaft 23 in a counter-clockwise direction, as viewed in Fig. 1.

The ink motion can be revolved for the purpose of inking up, or other reasons, while the ink motion is out of contact with the printing cylinder. n the shaft 3|, which runs across the ink motion, is securely mounted a gear 32 which engages with a gear 3| on the lower ink cylinder 3! of the ink motion. The cylinder 32 is geared to the rest of the ink motion in a well known manner.

The shaft 3| extends outside the carriage i and on the outside end is placed a clutch 33 slidably keyed to the shaft 3i and operated by the hand lever 33, which is pivoted on a bracket 33 secured to the ink carriage I. A free running spiral gear 34 is mounted on the shaft 3i and held in place by a collar 33., The side of this gear 34 next to the clutch has jaws to match the jaws of the clutch 33. This spiral gear 34 engages with the spiral gear 33 which is slidably keyed on the shaft Ii and moved along with the carriage l by cooperation with the bracket 33 secured to carriage I. From this it will be seen that, when the shaft is running, the spiral gear 33 will drive the free running gear 34. Then the gear 34 will idle on the shaft 3| until the clutch 33 is pushed into contact with the jaws on the gear 34. It will then turn the ink motion through the gearing described above.

The cam 31, secured to the rail 4, is a safety guide which will push the clutch operating lever 33 to disengage the clutch 33 from the gear 34. This stops the ink motion before the same contacts with the printing cylinder 3. This is desirable since the ink motion gearing meshes with gearing on the printing cylinder 2, and the printing cylinder 2 is at rest when the ink motion is moved into operating position, as in Fig. 1. A somewhat simpler modification for moving the ink motion is indicated in Fig. 7. A reversible motor 33 is mounted on a bracket 31 secured to a frame 33 and adapted to operate on an individual carriage. On the motor shaft is mounted a worm 33 which engages with a worm wheel 33 on the splined shaft 43, which latter is mounted on the one end in a pillow block 33 secured to a rail 33. This worm wheel 33 is loose running on the shaft 43 but kept from revolving thereon by a pin 3| in the clutch 33 which latter is keyed to the shaft 43. The reason for this clutch will be explained later.

Blidably keyed to the shaft 43 is a spiral gear 4| which engages with a spiral gear 43 and the spiral gear 43 is keyed to the shaft 43 which carries two pinions 44 and 44 which engage with racks 43 and 43' in a manner similar to the other arrangement.

For the control of the motor, it is well known to use a two-button system whereby the pressing of one button turns the motor in one direction and the other in the opposite direction. In Fig. 7a there is shown a three-pull hand switch which may be thrown to the forward side or to the reverse side. Then, if the dog 43 contacts with the button 43, the motor-will run to move the carriage in a forward or reverse direction and when the switch 43 or 41, as the case may be, is opened, the motor stops. The motor 33 is operated from the line Li L: which supply the field. The current to the armature has to pass through the closed switch 43 and through either one of the limit switches 43 or 41. Otherwise the motor cannot run because the armature is not supplied with current.

Limit switches 43 and 41 may be used to limit the motion of the carriage by stopping the motor 33 when either switch is contacted by a toe 34 of the spiral gear guard 32 which moves along the shaft 43 with the splined gear 4i. Another limit switch 43 may be used which when open will make the motor 33 inoperative until this switch 43 contacts with a hand operated lock dog 43 which looks the carriage 33, as shown in Fig. 7; This insures that the carriage 33 will be unlocked before an attempt is made to move the carriage 33. Wiring may also be so arranged that when the lock dog 43 contacts with the limit switch 43, the motor will be energized and start the carriage moving away from printing position.

If, for some reason, it becomes necessary to.

move the ink carriage manually as, for instance, in case of a motor break down, it is only necessary to pull back the lock pin 3i in the clutch 33,

which releases the worm wheel 33. A hand lever placed on the square end of the shaft 43 may 0 then be used to operate the carriage.

It is, therefore, evident that means are shown for shifting a movable ink carriage to and from a printing cylinder by power and selective means are shown for inking up the rollers carried by the carriage by power-driven means, when the carriage is away from the printing cylinder. It is understood, of course, that a number of these mechanisms may be used in combination to make up a printing press. The parts 3|, 33, 33 and 33 are the same as in Fig. 1 and will turn the ink motion through a clutch when closed as in Fig. 1.

While I have shown a single motor for moving the ink motion carriage to and from the printing cylinder, and for rotating the ink motion when the carriage is away from the printing cylinder by the use of mechanical clutches, it will be understood that I may employ a separate motor for otherwise than as set forth in the claims, but what I claim is:
