Application filed December 28, 1904. Serial No" 238.562.
To all whom it may concern.-
Be it known that I, RICHARD J. GREEN- WAY, Jr. a citizen of the'United States, and a resident of Westerly, in the county of Washington andState of Rhode Island, have invented a new and useful Improvement in Attachments for Ink-Fountains of Printing- Presses, of which the following is a specification.
This invention consists in an attachment for the ink-fountains of printing-presses, and has more particularly for its object to provide a device designed to prevent the supply of ink on the fountain-roll being transferred at a predetermined point to the ductor-roll.
A further object of this invention is to provide a device which may be removably attached in position between the fountain-roll and ductor-roll at any desired point along the same without requiring a specially-constructed fountain and without disturbing the set or adjustment of the regular fountainscrews.
A practical embodiment of my invention is represented in the accompanying drawings, in which Figure 1 is a detail vertical section through an ink-fountain and its adjacent parts with one of the attachments in position with respect to the same. Fig. 2 is a' partial plan view showing two of the attachments in position for use, and Fig. 3 is a detail plan view of one of the attachments.
The side frames of the press are denoted by 1 and 2, between which is supported the inkfountain. A fountain proper comprises a bottom 3 and uprising ends 4 and 5, from which project plates 6 7, attached to the side frames 1 2. The fountain-roll, which is denoted by 1, is rotatably mounted in the ends 4 5 of the fountain-frame. A false bottom 9 is fitted to slide between the ends 4 5 and is held in position on the bottom 3 by screws 10. The blade 11 is secured to the false bottom 9, with its forward edge normally spaced a slight distance away from the fountain-roll 8. A rocking plate 12 engages the under side of the forward edge of the blade 11 and is in turn engaged by a series of set-screws 13, by means of which the front edge of the blade may be adjusted so as to permit the required amount of ink to be deposited upon the surface of the fountain-roll.
The ductor-roll is denoted by 14; and it is mounted, as is usual, in the free ends of arms 15, carried by a shaft 16, the parts being so arranged that the ductor roll 14 may be brought into engagement with the fountainroll 8 and then into engagement with the form-inking apparatus (not shown herein) in the well-known manner.
It has heretofore been necessary where open spaces or margins occurred in the printing-form at which little or no ink was required to adjust the blade in the fountain with the adjusting-screws 13 unevenly, so as to cut off or stop the flow of ink onto certain parts of the fountain-roll. In doing this an undue strain has been brought onto the blade sufficient to spring and often at times to buckle, and thereby ruining it. The object of this present invention is toprovide a device which will eifectually prevent the supply of ink on the fountain-roll from being transferred to the ductor-roll at any point thereon without changing the adjustment of the blade at different points along the same, the blade being allowed to remain in its adjustment with respect to its fountain-roll. Myattachment comprises a thin strip of suitable material 17such, for instance, as sheet metalwhich strip may be inserted between the fountain-roll and ductor-roll. One end of this strip is removably secured to some suitable support-such, for instance, as the ductor-roll shaft 16. have shown for attaching-this strip comprises a button 18 and buttonhole 19, spaced a suf ficient distance apart along the strip to permit the end of the strip to be wrapped around the ductor-roll shaft and secured. I have provided means for holding the strip under tension, which means in the present instance consists of a wei ht 20, carried by the free end of the strip, t e strip being shown of sufficient length to permit the free end of the same to pass over the top of the fountain and depend therefrom. It is to be understood that I may provide other means than that herein shown for holding the strip under tension. These strips 17 may be made of various widths to correspond to the width of The means which I ICO the space on the ductor-roll which it is desired to protect from the deposit of ink, and it is to be noted that these strips may be adjusted laterally to any desired point along the roll.
It will be seen that by the use of these attachments the supply of ink on the fountainroll is prevented from being transferred to the ductor-roll at those points where the attachments are interposed between the two rolls without interfering with the adjust other point which may be found convenient.
What I claim as my invention is 1. A fountain-roll, means for supplying ink thereto, a ductor-roll, a strip of suitable material interposed between the two rolls to prevent transferring ink from the fountainroll to the ductor-roll at a predetermined point, a suitable support upon one side of the rolls, means for securing one end of the strip to the support and means en aging the free end of the strip upon the other side of the rolls for holding it under tension.
2. A fountain-roll, means for supplying ink thereto, a ductor-roll, a strip of suitable material interposed between the two rolls to prevent transferring ink from the fountainroll to the ductor-roll at a predetermined point, a suitable support upon one side of the rolls, means for removably securing one end of the strip to the said support and means engaging the free end of the strip upon the other side of the rolls for holding it under tension.
3. A fountainroll, means for supplying ink thereto, a ductorroll, a strip of suitable material interposed between the two rolls to prevent transferring ink from the fountainroll to the ductor-roll at a predetermined point, a suitable support upon one side of the rolls, means for securing one end of the strip to the said support and a weight carried by the free end of the strip upon the other side of the rolls for holding thestrip under tension.
4. A fountain-roll, means for supplying ink thereto, a ductor-roll, a strip of suitable material interposed between the two rolls, a suitable support upon one side'of the rolls, means for securing one end of the strip to the said support and means engaging the free end of the strip upon the other side of the rolls for holding it under tension, the said strip being capable of adjustment along the rolls to prevent transferring ink from the fountainroll to the ductor-roll at any desired point thereon.
5. A fountain-roll, means for supplying ink thereto, a ductor-roll, its shaft and a strip of suitable material attached to the shaft and interposed between the two rolls to prevent transferring ink from the fountain-roll to the ductor-roll at a predetermined point and means for holding the strip under tension.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 22d day of December, A. D. 1904.
