INKING-DISK FOR PRINTING-PRESSES.
Specification of Letters Patent.
Patented Feb. 3,1914.
Application filed June 27, 1913. Serial N 0. 776,082.
1" 0 all whom it may concern Be it known that I, FRANK J. ANrELorTI, a citizen of the United States, and a resident of Norfolk, in the county of Norfolk and State of Virginia, have made a new and use ful Improvement in Inking-Disks for Printing-Presses, of which the following is a specification.
My invention relates to improvements in inking disks for printing presses and it consists in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide an auxiliary disk which may be used in connection with printing presses having inking mechanism consisting of a plurality of concentric disks with means for oscillating or rotating the disks in opposite directions and thereby more evenly distributing the ink.
A further object of my invention is to provide an auxiliary inking disk which may be attached to the outer of the concentric inking disks and which will be spaced from the inner of said disks thereby permitting the free movement of the inner disk.
A further object of my invention is to provide a cover for the inner and outer inking disks which will serve as an inking disk itself and which, when removed, will permit the inking to be done by the inner and outer concentric disks which form part of the normal structure of the machine. 7
Further objects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming part of this specification, in which- Figure 1 shows the application of my invention to the concentric inking disks of a printing press of this character. Fig. 2 is a perspective view of the bot-tom portion of the disk which forms the subject of my present invention, and, Fig. 3 is a section through a portion of the attachable disk.
In Fig. 1 I have shown certain parts of the printing press, these parts being sufli cient to afford a clear understanding of the manner in which my invention is applied. In the figure, 1 denotes a support bavinga cross piece 2 at its top. A shaft 3 extends through the cross piece 2 and bears at its upper end an inner circular disk 4:. Surrounding the shaft 3 is a sleeve 5 which exwliich has tends through the cross member 2, and a flange 6 that bears upon the cross member. Secured to the top of the sleeve is a plate 7 which is provided with a central recess arranged to receive the plate 4, the upper surface of these plates 4 and 7 being flush. A gear 8 is secured-t0 the shaft 3 while a gear 9 is secured to the sleeve 5 and to the bottom part of the plate 7, in fact the gear 9 may be integral with the plate 7. An intermediate gear 10 is disposed on the drive shaft 11, and is arranged to engage both the gear 8 and the gear 9.
The construction described thus far is old and forms no part of my invention exceptin so far as it cooperates with the attachable plate as hereinafter described. It will be understood that when power is applied to the shaft 11, so as to oscillate or r0- tate the latter, the inner concentric disk or plate 4: will be revolved in one direction and the other disk or plate 7 will be revolved in the other direction. An inking roller pass ing over these two disks will have the ink distributed upon it with comparative uni- V formity.
It often happens that it is necessary in presses, of this type to change the colors. If, forinstance, black ink has been used and it is desirable to run green, yellow and any of the lighter colors, the black ink must be thoroughly cleaned from both plates before the run can be made. It will be found that the inks will work their way in be tween the disks and it is therefore necessary to take out the small inner disk 4 and to thoroughly clean the ink with some sol vent such as benzin. This as will be readily seen necessitates considerable trouble, and as stated above the object of my invention is to provide an attachment which will obviate the necessity of removing the concentric disks or of even cleaning them.
Referring now to Fig. 2 it will be seen that I have provided a circular disk or plate 12 which is made preferably of saw steel of an inch in thickness, and rounded on its outer edge as shown at 12, see Fig. 8, where the disk comes into contact with the inking roller. On the under side of the disk 12, and preferably at points 90 apart, I arrange a series of spring clips. Each spring clip consists of a body portion 13 having a laterally bent portion 14, this bent portion being curved inwardly and then outwardly as clearly shown in the drawings. In order to reduce the space which the spring 13 occupies, I prefer to recess the plate 12 slightly and to countersink the spring member 13 in the recess. The auxiliary disk 12 is applied by placing the latter on the disk 7 and forcing the spring catches 14 over the edge of the disk or plate 7. This will hold the auxiliary disk 12 and Will cover the concentric disks 7 and 1.
W'hen the roller, not shown, comes upon the auxiliary disk 12 it Will ride upon the same and will be inked by any ink which is placed on the disk 12. It will be observed that the body portion 13 of the spring members extend slightly below the surface of the disk 12. This raises the disk far enough from the concentric plate at so as not to interfere in any way with the operation of the latter. The press may then be run as usual and the ink may be of a different auxiliary disk or plate 12 may be quickly applied and quickly removed, and it is comparatively cheap to manufacture.
I claim:
1. The combination in a printing press of a pair of concentric inking disks, said disks being rotatable with respect to each other, an auxiliary disk arranged to cover both of said concentric disks, and means secured to the under side of said auxiliary disk for removably securing the latter to the outer of said concentric disks, said means also serving as a spacing means for I spacing said auxiliary disk from the inner of said concentric disks.
2. The combination in a printing press of a pair of concentric inking disks, said disks being rotatable with respect to each other, an auxiliary disk arranged to cover both of said concentric disks and having color from that of the concentric disks 4L and 7 When it is desired to again use i the concentric disks for inking purposes,
rounded edges, and a series of spring clips arranged symmetrically on the under side of said auxiliary disk, said sprlng sllps having the spring members 141 may be pried outwardly with a screwdriver or other con- Venient tool, and the auxiliary disk 12 may be removed.
It will thus be seen that I have provided a device Which Will greatly expedite printing operations, is being done. The outer disk 12 entirely covers both concentric disks, and there is no danger of the ink upon the latter interfer-v ring with the use of the auxiliary disk. The
a body portion arranged to engage the upper side of the outer of said concentric disks, and having spring extensions arranged to engage the edges of the outer concentric disks 'or holding the auxiliary disk in position, said clips serving to space said auxiliary especially where color work disk from the inner of said concentric disks.-
