PATENT JOHN J. SULLIVAN, F CINCINNATI, OHIO.

Application filed December 18, 1924. Serial No. 756,758.

To all whom it may aonbern:

Be it known that 1, JOHN. J. SULLIVAN, a

. citizen of the United States, residing at the Presses, of which the following is a specifi-' cation.

The object of my invention is to provide an inking attachment for bed and platen job printing presses which will allow for the even, uniform, and constantly eflicient distribution of the printing ink, preparatory to placing the same upon the type or form, readg for the printing operation itself.

I ispense with the usual ink carrying circulating disc well known in the art in this form of printing presses, and provide a plate usually semi-cylindrical in contour which I call a vibrating distribution, plate, which vibrates forwardly and backwardly upon which ink is deposited and I provide means for thoroughly, evenly and uniformly distributing the ink thereon, forming a film of ink thereon which will'produce a film of ink of the same density and thickness, throughout, which is transferred to the inking rollers which place the same upon the typeor form, ready for the printing operation 1tself, insuring an even and uniform application of ink to the type, plate or cut being used.

In order to thoroughly distribute the ink and place it uniformly and evenly upon the distribution plate, my distribution plate vibrates forwardly and backwardly and 3 presses against the rollers which carry the ink, theserollers remaining stationary and in this manner the distribution plate by its vibrating action takes the proper amount of ink 03 of the rollers, hence it is evenly distributed on said plate.

My attachment is simple, highly efiicient in operation and dependable for uniform work, possessing great utility.

Itis a well known fact that in order to do a, good job ofprinting, the ink must be evenly and uniformly distributed so that the printing itself will be of a standard, uniform, and even appearance upon the paper 11 on which the printing is done, so as to be "p easing to the eye and show good workmanship in its appearance.

With my attachment I overcome any defects nowjpresent in the bed and platen printing presses now used, as to the proper distribution of the printing ink.

Thevarious features and advantages of my invention will readily become apparent from a perusal of the following specification and claims.

In the accompanying drawing forming part of this specification:

Fig. 1, is a view in elevation of a printing press, showing my device in position,

Fig. 2, is a rear view in elevation of my device,

Fig. 3, is a side elevation of one side of the device,

Fig. 4, is a view in elevation of the other side of my device,

Fig. 5, is a plan view of the device, and

Fig. 6, is an enlarged plan view of the cam lever and its connecting working parts.

In carrying out my invention as shown in the drawing, I illustrate an outline of a bed or platen job printing press in order to better describe m device or attachment.

Located in the side frames 1 of the printing press, is the shaft 2, on which I pivotally mount one end of the roller arm 3, the other end is mounted to an arm 4 mounted on a rock shaft 5, which is supported by the beams 6, the beams being in turn, held securely in the rocking bed 7 of the printing press. Mounted on said shaft, at both ends, are the side platesj8, 8, and at their upper edges 9 I place the semi-cylindrical, vibrating curved ink distributing plate 10.

On both sides of the distribution plate 10 I place the curved brackets or guards 12, 12, one end of which is fastened in the beams 6, at point 13, the opposite end being fastened to the rocking bed 7 of the printing press, at the point 1st.

On the brackets 12, I place the auxiliary brackets 15, in which I mount the shaft 16; at one end of Said shaft I place the roller link 17 'and the hpposite end of said shaft 16 is mounted in one arm of cam lever 21 which link 17 and lever 21 carry the ink feed roll 19, which is mounted on the shaft 20, one end of which shaft being mounted in the cam lever 21, which is pivotally mounted on the stud shaft 22, supported hy the beam 6. In the upper extremity of the arm 23 of the cam lever 21, I pivotallv mount the cam roller 24, which engages t e cam 25, mounted on the side 8'. A recessed portion 26 of distributes it over the I end of the lever 29 I mount one end of the rocker arm 30 and at the other end of said rocker arm 1 plvotally, mount the pawl 31;

this pawl engages the ratchet 32, which is mounted on one end of the shaft 33, said shaft being securely mounted in the rocker arm 30, near its center.

The shaft 3; also carries the ink roll 34: which is located in the ink fountain 35.

Mounted on the brackets or guards 12 are the ink distributing rolls 3U, 37, 38 and 39 and between these rolls is the agitator vibrating roll 40. These rolls are of the usual form now well known in the art, andneed not be further described.

On the ink fountain 35 I'provide the adjusting screws 41, they regulating the sup ply of ink and as they are well known in the art, they need not be further set forth.

I will now set forth the operation of my device or attachment as connected to a .bed or platen job printing press. As the rocking bed 7 of the printing press rocks backwardly andforwardly, the lever arm 3 rocking on the shaft 2, which is held stationary in the side frames l of the printing press causes the distribution plate 10 and the side plates 8 and 8 to rock back and forth on their shaft 5 by reason of small arm 4 being connected to the lever 3. It will be seen that when the bed 7 moves backwardly and forwardly with one end of lever 3 held stationary and the other end connected to the arm 4, mounted on shaft 5, said shaft 5 being carried by the bed itself, a rocking action will take place, with the distribution plate 10. In other words, said plate 10 will be. vibrated.

As the distributing plate l0 vibrates or rocks back and forth, the plate 8 carrying the pin 27, which riding in slot 28, after having reached its limit of travel, said pin 2-7 will carry with it the lever 29, causing the pawl 31 to ride backward through medium of link 30 so that when the distribution'plate 10 returns, and the pin 27 return to its limit of travel at the opposite end of the slot 28, it carries said lever 29 with it. to a predetermined point, causing the ratchet 32 to revolvethe ink roll 34;, through the medium of the lever 30 and the pawl 31.

As the distribution plate 10 rocks or vibrates back and forththe cam roller 24 engaging cam 25 at the recess 26 allows the feed roll 19 to take its supply of ink from the intermediate feed roll 42, which, in turn, late 10, when the roller 24 passes out of t e reccss'26 on the cam 25, allowing the feed roll 19 to contact with. the vibrating distribution plate 10 as said plate passes underneath the roller 19. in order to keep the even distribution of ink on plate 10, I also provide the agitator rolls 36, 37, 38, 39 and 40. These rolls are well known in the art and need not be further described.

' The rollers 50, there being three in the present" instance, are the ones which take the ink off of the distribution plate I0 and tranfer it to the form having the type or printing matter thereon, see Fig. 1. The distribu tion plate 10 vibra es forwardly and baclf wardly and vibrates backwardly to receive a fresh supply of ink and then moves forwardly and as it moves forwardly the rollers 50 which place the ink upon the form carrying the type moves up on its face to receive the fresh ink, and while said roll ers :30 are moving downwardly to place said ink upon the form carrying the type, the distribution plate 10 is moving backwardly to receive a fresh supply of ink and this movement is kept on as long as printing is being done.

Through the medium of adjusting screws 41 more or less ink can be allowed to pass upon the distribution plate 10 as desired and in this manner a film of ink upon said distribution plate may be heavier at one point than at another. This being the case when more ink is desired to be placed upon the printing form at certain places. example, if a sheet had to be printed with light small type at one end and havinglar e and dark typeat the opposite end of s id sheet, then I would place more ink on the distribution plate at the point where the large type would come on the sheet when printed and less ink where the small letters would come. during the printing process;'a better, superior and more Workmanlike job would result, and the appearance of the printing enhanced. The ink would be evenly distributed under these conditions, except that more ink would be distributed atone point than at the other, but it would be distributed evenly for this job and every separate sheet printed. From the foregoing, it will readily become apparent that various colors may be applied to various areas extending longitudinally of the elongated face of the distribution plate, whereby a multicolor printing job may be handled on a job printing press, care need only be taken to prevent overlapping of colors.

The distribution plate 10 may be of other form or contour than herein specifically shown and described and I may support For any

it-in position in any other manner to form and carry out the vibrating plate as described. i

is a preferred one, but I may deviate-from eer "nor a the same and modify it. so long; as it falls w'ithin the scope of this specification and. claims. v
