INKING APPARATUS FOR PRINTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 236,566, dated January 11, 1881.
Application filed Apr-i120, 1880.
To all whom it may concern:
Be it known that I, ROBERT ENGELS, a citizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State ofPennsylvania, have in vented new and useful Improvements in Ink-Fountains for Printing- Presses, of which the following is a specification, reference being had to the accompanying drawings, wherein Figure 1 is a plan of an ink-fountain with my improvements applied thereto, two of the partitions being shown with the depressingsprings removed. Fig. 2 is a front view of the same with inkingroller removed and its frame in section; and Fig. 3 is a vertical section on line 1 1, Fig. 1.
My invention has for its object to provide a printing-press ink-fountain with partitions which divide the same into compartments or sections, each of which is adapted to hold ink of a different color or shade from that in all the others, said partitions being so constructed that they will adjust themselves automatically to the rise and fall of the knife which forms the bottom of said fountain, in order to prevent the mingling of the different inks or their flowing into compartments other than their own.
My invention accordingly consists in the peculiar construction of the partitions aforesaid, and in their combination with the ink-fountain and inking-roller, said partitions each consisting of the following parts: a stationary holder secured to the step of the fountain, a sliding block moving in guides in the forward part ofsaid holder, and aloose crescent-shaped knife fitted in a concave groove in the face of said block, with springs which bear the latter down upon the bottom of the fountain and toward the inking-roller.
It further consists in certain details of construction and combination, hereinafter fully set forth.
Referring to the annexed drawings, A indicates a printing-press ink-fountain having a step, a. B is a knife or spring blade, which forms the bottom of said fountain, being secured in a kerf, a, in the step a, its opposite edge, I), impinging against or being in close proximity to an inking-roller, G. Said knife B is vertically adjustable by means of screws (No model.)
61 01, whereby its edge 7) maybe moved down 1 from or brought close up to the periphery of the roller 0, so as to increase or to diminish, as may be required, the flow of ink from the fountain to said roller.
The foregoing specified parts may be of the usual or any suitable construction, as they form in themselves no part of my invention.
E E represent partitions whereby the fountain A is divided into separate non-communicatin g compartments or sections, each one of which is designed and intended to hold ink of a different color or shade from that heldin the others. Each of said partitions consists of a rigid or stationary holder, E, made fast by a screw, 6, to the step a, or to a bar, G, secured to or upon said step. The forward or opposite end of said holder is provided with exten sions e e, which form guides for a block, E snugly fitted therein, but capable of sliding up and down. The outer edge or face of said block is formed with a concave groove, 6 'in which is fitted a crescent-shaped knife, E whose concave edge e is concentric with and fits tightly against the ink-roller U.
E represents a spring secured at e to the holder E, its opposite end resting and hearing downwardly upon the block E near its outer edge. E is another spring, located between the holder E and block E the purpose of which is to press said block outwardly, so as to maintain the knife E always in contact with the inking-roller.
The operation is as follows: By the employment of the partitions E the ink-fountain is divided into as many sections or compartments as may be desired. When it is desired to regulate the flow of ink from the fountain the knife B is adjusted by means of the screws d d. If said knife be lowered, the blocks E will follow it, sliding in the guides c 0, being pressed down by the spring E. The knives E will also descend to prevent ink passing under their lower points, and will at the same time slide circularly in said blocks, so as to maintain their concentricity with. the roller 0,
and thereby prevent inter-mingling of the inks over their edges. When the knife B is raised the blocks E will be elevated correspondingly in their guides, the knives E being lifted at the same time and by the same motion, and
sliding circularly upward in impingement and concentricity with the roller 0.
The bases of the blocks E may have fitted in them packing-strips, of felt or other equivalent material, to prevent ink in one compartment of the fountain finding its way into another compartment underneath said blocks.
The heads of the screw-bolts e which fasten the holders E to the step a fit partly in a groove, a in said step and partly beneath the bar G, which rests on or above the latter. To adjust the partitions E along said step so as to vary the size of the ink-fountain compartments, the nuts 0 are loosened, permitting the holders, with said screw-bolts, to be moved along the step, and in any desired position thereon. The screw-bolts a pass through slots 6 in the holders E, whereby the latter may be adjusted toward and from the roller 0.
The points 6 of the knives E should be beveled on either side, as shown at e 0 whereby a wide line of separation on the inking-roller is avoided between different inks.
What I claim as my invention is- 1. A printing-press ink-fountain partition consisting of rigid or stationary holder E,
with extensions 6 e, sliding block E having concave groove 0 and crescent-shaped knife or blade E fitted in said groove, with springs E E substantially as shown and described.
2. In combination with an ink-fountain, A, havingadjustable bottom plate or knife, B, and ink-roller 0, one or more partitions, E, for dividing said fountain into compartments, said partition or partitions having a vertically-adjustable knife or knives, E with concave edge or edges a, concentric with said roller, and holder E, substantially as and for the purpose set forth.
3. In combination with an inking-roller, O, a crescent-shaped knife fitted in a groove and forming the front edge of the partition of an ink-fountain, and provided with a suitable holder, E, substantially as and for the purpose set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 14th day of April, 1880.
ROBERT ENGELS.
