as from the accompanying drawings, .in which Fig. 1,.is a fragmentary top plan view of an ink-distributing disk and main ink-distributing rollers having an attachment indicated in proper relation to the ink-distributing disk whereby a different color may .be maintained on .the strip with-reference to the ink or color on the main disk, and having an attachment indicated in certain relation to the main rollers whereby the color taken from the strip or .band may be properly distributed over a certain portion of the main rollers to supply two or more colors to-types in a .printingpress according to this invention.
Fig. 2 is a fragmentary side elevation of the distributing disk and rollers with the :attachine-nts illustrated in Fig. 1.
Fig-.3 is afraginentary'detail top plan view of the=additional or smaller distribu'tingrollers whereby ink taken up by the main r ollers is distributed proper-1y over a certain portion ofthe ma-in rollers.
- Fig. 4 is a fragmentary detail topplanview of a. stationary pin with "certain threaded portions whereby a roller is automatically moved backand forth for distributing ink.
Fig. .0 '18 a cross-sectionthrough a roller having a follower or engaging member piv= otally provided in ,itsinside to engage the roller withthe threaded pin so that the'rol-ler will bemoved. back and torth when rotated around the pin.
As illustrated, the inkrdistri-buting disk 6 is customarily used to transmit ink to the main. ink-distributing rollers 7. A proper and desired distribution of ink between the disk '6- and therollers 7 is facilitated by the turnable mounting of the disk at 8 .so that the disk can be rotated to a suitable :extent from time to'time to bring certain portions of the rollers 7 over different portions of the "diskin successive operations of the rollers. Theink received by the rollers from v the disk -is:transferred in a required amount over'tlie surface of types or aitype chase in the press :bed 9' when the roller 7 onithe rocking arm 10'is so moved. Any-card paper, or
'otherzsimilar.Earticle upon: the surfaceof which an imprint is to be made upon being placed on the surface 11 of a platen 12 will receive the color or ink from the ink or colorcovered types whenever the platen is brought into contact with the press bed.
In addition to these transferring facilities of ink or color an attachment is provided in av certain relation to the ink-distributing disk and another attachment is applied in a certain relation to the ink-distributing rollers.
The first-named attachment consists principally of an ink-distributing strip 13 and a support 14. The support is firmly secured to any comparatively stationary part of a frame structure upon which the rotatable disk 6 is mounted as indicated at 15.
One portion on bar 16 of this support extends laterally along one side of, and in a suitable relation to, the surface of the inkdistributing disk 6.
The ink-distributing strip 13 is preferably made of spring material, such as hand or ribbon steel, normally to maintain itself in a certain position spaced from the surface of the ink-distributing disk as indicated at 17 in Fig. 2, and adapted to be pressed down close to the surface of the ink-distributing disk when the ink-distributing rollers pass over it and thereby over the ink-distributing disk in order to allow a proper contact between the ink-distributing rollers and the disk though under this arrangement the inkdistributing strip is to a certain extent be tween the ink-distributing disk and the ink distributing rollers while the rollers pass over the disk.
One end of the ink-distributing strip 13 is adjustably secured to the portion 16 of the support 14 by any suitable clamping means indicated at 18 and which is adjustable along portion 16 and through which one end of strip 13 is adjustable, while the other end of this strip 13 is provided with a pin-like termination 19 slidingly disposed within the bifurcated end 20 of the clamping means or structure 21, and which end 20 extends away and downwardly from the clamping means 21, as shown in Fig. 2. The clamping structure 21 being slidable along or adjustably mounted on the lateral portion or supporting bar 22 of the lower frame portion 1 1 so that the clamping structure 21 may be adjusted laterally in suitable relation to the clamping structure 18. The bar 22 extends along the inkdistributing disk 6 on the side opposite bar 16. A thumb screw A serves to clamp or bind the strip 13 to bar 16in rigid relation thereto.
With this arrangement the ink-distributing strip 13 can be placed so as to pass over the ink-distributing disk 6 in various relationsto the surface of the ink-distributing disk from one side to the opposite side.
By placing ink of a certain color on the distributing disk and another ink of another color on the distributing strip such two colors are naturally transmitted to the main distributing rollers 7 when these pass over the disk and strip, to result in a printing of these colors on any material placed on the platen which is clearly demonstrated in Fig. 1 by having the platen with the printing surface thereon shown in horizontal top plan view.
A card 33 placed on the platen 12, for instance, can receive a black impression in words as indicated at 34: together with a red impression of the numeral 2, indicated at 35, in one operation. After the card has been turned around the black writing impression indicated in dotted lines at 3 1., and the red impression indicated in dotted lines at 35 can be produced in a second operation.
Various colors, of course, can be used and two or more colors can be applied in the manner set forth above as will easily be understood without further illustration or explanation by the mere mounting of additional inkdistributing strips and supplemental rollers. The card roughly outlined in Fig. 1 at 32 after the two impressions have been made is merely cut in two so that two cards with two colors are made in two operations in that case. However, inasmuch as certain portions of the main ink-distributing rollers 7 pass again and again invariably straight across or over the ink-distributing strip 13, whereby eventually the same spot of either of the main distributing rollers may come repeatedly into contact with the same spot on the inkdistributing strips, additional laterally movable distributing rollers are mounted in certain relation to the main distributing rollers tofacilitate and assure a proper and even distribution of ink or coloring on the main distributing rollers over the portions of the main rollers 7 that pass over the strip 13.
I This supplemental distributing roller structure is illustrated in detail in Figs. 3, 4 and 5. The whole supplemental structure is adjustably mounted along the rod 23 held between collar rings 2-61. A central roller 25 is turnably mount-ed with its shouldered ends 26 in the cross members 27, being hollow throughout and serving to support the whole supplemental structure shiftable and adjustable on the rod 23 while the roller 25 may turn on the rod in any certain adjusted position.
Threaded studs 28 are firmly secured between the cross members 27, and sleeve-like rollers 29 are shiftably and turnably mounted on the threaded studs 28 adapted to move laterally from and to the opposite ends of the studs between the cross members 27 while at the same time rotating around the studs. The lateral turning movement of the sleevelike rollers 29 is produced by the sectioned or cross-cut thread structure indicated at 30 in Fig. 4 in combination with a thread following member 31 pivotally mounted within the sleeve 29 as indicated at 32.
From the above description and the accompanying drawing it must, furthermore, be clear and understood that the strip 13 can also serve for blank printing. If, for instance, a blank strip is required or desired across a page in which later on a certain name or insertion is to be made, a strip like the one designated by the numeral 13 can easily be arranged across the ink-distributing disk 6 with no ink on the strip 13 so that the main distributing rollers T will receive no ink from the main distributing disk 6 and therefore can transfer or transmit no ink to any type on the press bed or in the type chase.
From the foregoing, it will be seen that the ink distributing strip 13 is rigidly secured to the supporting bar 16 while the end 19 of strip 13 is loosely mounted relative to bar 22 for depressive movement thereof. The upper end of the slot forming the bifurcated end of the clamping means 21 limits the upper travel of the end 19 of the strip 13 and also determines the distance the strip 13 will,
by its normal spring, hold itself above the disk 6. This distance or space 17 provides a construction that will not scrape the ink off from the disk 6 when said disk is intermittently rotated. YVhen the rollers 7 pass over the disk 6 they will also pass over, the strip 13 and the end 19 of strip 13 being freely movable toward said disk 6 against the normal tension thereof will be depressed so as to lie flat against the disk 6 so that the rollers 7 will not be unduly depressed. The instant rollers 7 leave the disk 6, and strip 13, the strip will be automatically raised by its spring tension, away from disk 6 when the rotating movement of disk 6 takes place.
Having thus described my invention, I claim:
1. In a printing press attachment, in combination with an ink-distributing disk and main ink-distributing rollers, an ink-distributing member disposed across the surface of the said disk so that said rollers can be supplied with diiferent inks from said disk and the ink-distributing member when the rollers are passed over the disk and member, and a pick-up roller with secondary ink-distributing rollers mounted for rotating as well as lateral movements back and forth longitudinally over and in certain relation to the firstnamed rollers and to the said member whereby ink taken up by a certain portion of the first-named rollers is distributed and evened by contacting with the secondary rollers.
