SPECIFICATION forming part of Letters Patent No. 291,843, dated January 8, 1884.
Application filod February 10, 1860.
T0 allwhom it may concern:
Be it known that I, Mnnnir'r GALLY, of the city, county, and State of New York, have made certain new and useful Improvements in Printing-Presses, of which the following is a specification.
My invention relates specially to that class of presses known as jaw-presses, in which the bed and platen open at an angle; but some parts of the invention may be used in other forms of presses.
My invention consists, first, in an arrangement of the ink-distributing rolls in such manner that the rolls may move over the distribu tion-table in lines other than straight lines; secondly, in such a connection of the drivingpower with the rolls that ink-distribution may take place on the distributing-table without the necessity of inking the forms; thirdly, in an improved arrangement of tympan with relation to the bed and platen.
In the drawings, Figure 1 is a side view of so much of apress as is necessary to illustrate my invention. Fig. 2 is a detail showing the other end bearing of the distributing-rolls. Fig. 3 is a perspective of the distributingtable, showing the rolls thereon, and the track of the rolls in dotted lines. Fig. 4: is a side view of platen and tympan in closed position.
Vihile it has been common to move the inkdistributing rolls in oblique lines on the dis tributing-table of cylinder-presses, in which the bed of the press is in the same plane with the distributingtable, it has been impracticable heretofore to accomplish such oblique movement of the rolls over atable not in plane with the bed. This result I accomplish in the following manner:
Let R represent the bed of a press, and m the ink-distributing table, forming, if desirable, a continuation of the bed, but in a different plane. The tablem is preferably made in two planes, on m which are arranged with relation to point N substantially as shown. The roller-frame T is pivoted at N, and has a set of inking-rolls, y, of the usual construction in this class of machines. A part of frame T, however, or it may be a separate frame connected in such manner as to move therewith, has a separate set of rolls, a, which serve as distributing-rolls. A counter-weight, S,
serves to hold the rolls normally above the type-form on the bed, or other usual mechanism may beused for such purpose. The frame or part of the frame which carries the set of rolls a has slots of n for the journals i z'of the rolls. These slots of a are nearest the sides of the frame at their ends toward the pivot N, and converge as they reeede from said center. The slots a n, in which the other end journals of the rolls have their bearing, diverge, as they are farther from the center, so that when the rolls are at some place between the ends of the slots they will be parallel, but when at the ends they will be oblique, to each other. Now, as the rolls a oscillate about the center N, in the operation of the press, they will, in passing over plate at m, necessarily approach and recede from the center N. At the lowest depression of the rolls they will be in a position oblique to the table and oblique to each other; but in riding over the highest part of the table they will be in a position parallel therewith. The upper roll will be parallel with the upper part of the table at the point E, and may there receive a supply of ink from a fountain or a doctor-roll. It is evident that the oblique movement takes place on each plane-table. Therefore the number of such tables need not be limited to two.
The slots 92/ a may be differently arranged, or other mechanism may be employed to pro duce the oblique movement of the rolls, without departing from the spirit of my invention. The inking-rolls y pass over a part of the table at over which the rolls a have passed in an oblique position when they come up over said plate to receive their supply of ink. In moving down over the form the rolls a follow the rolls y no farther than the edge of the dis: tributing-table, or at least not to the form.
To give more effective distribution to the ink, it is sometimes desirable that the rolls be kept in mot-ion over the distributingtable for some time without bringing them in contact with the type-forms. This may be accomplished in the following manner: I attach to the frameT, which carries the inking-rolls, a draw-bar,-b, which is connected to a stud, t, 011 the platenof the press, saidstud t passing through a slot, 71, in bar b. A turnbutton or stop, a, is pivoted to bar I) in such manner that when turned in one direction it will close the slot in part, leaving only room for the passage of stud it, but when turned in the other direction it will permit a play of the stud t in saidslot. position by a spring, 0 bearing on flattened surface a, or by friction. When the stop a is turned to close slot h, the movement of the platen will draw the rolls with it; but when sloth is left open, the pin it will have movement therein, and will only draw the bar I) when it has reached the end of said slot. The length of the slot should be such that when the pin 25 reaches the end thereof it will then move the rolls, but not far enough to bring them on the form. The counter-weight will draw the rolls up again as soon as the movement of the platen permits.
The location of slot and pin may be changed, and other obvious modifications be made without d eparting from the spirit of my invention.
The draw-bar may be operated from the platen, or any other moving part of the press.
The next part of my invention consists in the combination with a jaw-press, or with the platen thereof, of a tympan or plate, which shall be in nearly a horizontal position when the platen is thrown back, so as to be in con-- venient position for feeding the sheet thereon.
A represents the platen of a jawpress, which is pivoted to the bed or frame. The plate or tympan A is pivotedto the front or top edge of such platen, as at 11, while the other edge is pivoted at x to the rocking link 0, which is connected by a pivoted link, 0", as shown, to the frame. The link c is not permitted to fall so low but that the link a will retain the enda" of the tympan in elevated p osition when the platen is swung back. hen the platen closes against the bed, the tympan A will at the top move in thedotted line 1) in until it comes against the bed; The bottom of the tympan will, by the movement of the links, drop or swing back against the platen.
Vhat I claim is 1. The combination, in a printing-press, of a distributing-table in a different plane from the plane of the bed, of ink-distributing. rolls, arranged, substantially as deseribed,to move over the table in lines oblique to the table and oblique to each other, and suitable operative mechanism, substantially as described.
2. The combination, with the distributingtable of a printing-press, of ink-distributing rolls which move over a part of the table in lines parallel to the edge thereof, and'over part of the table in lines oblique to the edge thereof, and suitable operative mechanism, substantiallyas described.
Turn-button a may be held in either I 3. The combination, table of a printing-press, having its surface in more than one plane, of ink-distributing rolls which move over said table in oblique lines, and suitable operative mechanism substantially as described.
4. The combination, with the distributingtable of a printing-press made up. of more than one plane, of ink-distributing rolls which move over the plane surfaces in an oblique direction, but which pass over the line of junction of said planes in a line parallel therewith, and suitable operative mechanism substanstially as set forth.
5. The combination, with an ink-distribuing-table made in a plurality of planes, as de- 7 scribed, of the rocking-frame carrying inkdistributing rolls, said rocking-frame being provided with inclined slots, the slots in one end of the frame being inclined in the oppo site direction from those in the other end, substantially as set forth.
