FEEDING DEVICE'FOR PLATEN-PRESSES.
SPECIFICATION forming part of Letters Patent N o. 628,158, dated July 4, 1899.
Application filed June l0, 1898.. Serial No. 683,Q80. (No model.)
To all whom, it may concer/t:
Beit known that I, PETER DVORK, printer, of 21 Bennogasse, Vienna, VIII, in the Empire of Austria-Hungary, have invented certain new and useful Improvements Relating'v to the Feeding of'Sheets of Paper and other Material to Printing-lvlachines and to Apparatus Therefor, of which the following is a description.
The subject of the present invention is a platen-press with automatic device for feeding and delivering sheets, according to which the feeder catches up the top sheet of the paper pile by means of its viscous or sticky Working surface and carries it to the platen of the press, where it is printed. It is then lifted out and seized by the delivery-sticks or fly-sticks and delivered to another pile.
In the drawings, Figure l shows a section immediatelybehindthefrontside plate. Fig. 2 is a plan view, while Figs. 3 and 4 represent different positions of the movable parts.
Before describing the invention proper the platen-press as known will be explained in detail. On the shaft 3 of the frame l is the fly and driving wheel 2, which revolves the shaft by means of the toothed wheels 4 5. On this shaft arms 7 are loosely arranged, around the pivot 8 of which the platen 9. pivots, said platen serving to receive the sheet to lie-printed, and connects by links 10 with the printing-plate 1l, which serves for the reception of the types. The printing-plate 11 swings around the shaft 12, which in turnswings around the pivot 14, by means of con` necting-rods 13, and connected by further connecting-rods 15 with crank-plate 16, arranged on the shaft 6. The printing-plate 11 is balanced by a weight v17 and connects with' the friction-plate 18. This construction produces the peculiar movement of lthe platen and the printing-plate, which open for the reception of the sheet and then close for printing it.
The automatic feeding and delivery device consists of the following: On the stud 8 aracksegment is pivotallyarranged, being weighted by a weighty 2O and assuming a vertical position under the sole influence of the same. On the right side of the platen a shaft 21 is journaled on the stud 8 by means of the arms 22 in such a manner that it cannot change its position in relation to the platen. On this shaft a toothed wheel 23 is fixedly arranged, said toothed wheel engaging with the racksegment 19. Moreover, this shaft carries a number of at rod-shaped feeding-sticks 24- two, for instance-which can be set by means of a screw device in accordance with the size of the sheet at various distances from eachother and which are provided with viscous material on the catching side, so that each top sheet sticks to the feeding-sticks, and is so carried into the machine. r
' Any known material can be used as a sticking medium. A sticking mass consisting of about one and three-fourths to two parts of gelatin and about ten parts of glycerin is recommended, and this mixture will secure a reliable attachment of the sheet with a moderate pressure. In order to reduce the sticky contact-surface when feeding tine or thin papers and material, it is well to cover one part of said contact-surface with a non-viscous material. The paper pile 25 is carried on an apparatus, which is provided with straightening pins or sheet-joggers, which separate when receiving a sheet and return thereafter, so that the paper pile is jogged together.
The delivery device consists in the following: The doctor-cylinder 28, which serves the purpose of taking ink from the roller in the ink-box 29 and to transfer it to the inkplate 18, is driven by the oscillating shaft l2 by means of the lever-weight 31, which is pivotal around 32, glides on this shaft, and is connected with this doctor-cylinder by the draw-bar 33 and the double lever 34. The fly-sticks 35 are xedly arranged on a shaft 36, which is pivotally journaled in the frametop 37 and carries a toothed wheel 38, into which engages a rack 40, connected pivotally with the pivot or stud 39 of the lever 34. This rack has a slit 41 on its top, and a stud 42 of the frame engages in the slit for the purpose of guiding the rack.
The ily-sticks are bent at right angles at their extremities, and these bends strike the rod 44 when the sheet is delivered. This will be mentioned later on. The apparatus 45 which serves to receive the delivered sheets is pivotal around the studs 46 and can be placed into various slanting positions by means of the slitted segment 47 and the screws 48.
IOO
The manner of working the machine, starting from the position shown in Fig. 3, is as follows: In that position the machine is locked, and the feeding-sticks, with the paper sheets, are situated between the platen 9 and the printing-plate 11. If the machine is moved in the direction of the arrow, platen and printing-plate separate, because the shaft 12 is removed from the shaft G. By means of the weight 17 the platen and printing-plate are drawn asunder in such a manner that the platen on the one hand pivots around the stud 8 into a more horizontal position and on the other hand the arms 7 are raised. As the weighted rack maintains its vertical position, the toothed wheel 23 will roll over on the rack-segment 19 owing to the turn of the platen, and this produces arevolution of the shaft 21 and the feeders 24, with the printed sheet, in the sense of the delivery or y sticks, Fig. 3. These iiy-sticks remain still at rest during this movement, because the shaft 12 cannot influence the weights 31. IVhen the machine has reached the positionshown in Fig. 3, the lower arm of the rack-segment strikes on the head 49 of the shaft 6, while the pivots 8 pass on to the right. Thereby the rack-segment is moved slightly to the right, causing a retrograde movemen t of the feedingsticks. At this moment the sheets are seized by the fly-sticks or delivery-sticks. The weights 3l have been turned to the left by means of the shaft 12 in the meantime and the stud 39, with the rack 40, has been pulled down in consequence, whereby the toothed wheel 38, the shaft 36, and the Iiy-sticks 35 are turned in the direction of the arrow. The latter strike over, passing between the feeding-sticks. They seize-the sheet and carry it upward until the extremities 43 strike the bar 44. By this stroke the sheet is lifted a little and slides along the delivery or iiy sticks upon the paper pile. Meanwhile the platen turns into a more horizontal position,while the pivot 8 goes back somewhat to the left, Fig. 4, the rack-segment resumes its horizontal position, and the feeding-sticks drop upon the paper pile owing to the revolution of the shaft 21 caused by the resumption of the horizontal position of the rack-segment. Then they seize the top sheet by means of their sticky or viscous surface and carry it to the platen. The platen turns to the left again, but the racksegment remains in vertical position, though consequently the feeding-sticks must turn in the direction of the feeding until they and the sheet lie down flat on the platen. During back into theirinitial position.
tion is repeated with each revolution of the crank-plates 16. Oseillations of the segmentlever resulting from rapid work can be prevented by various means-for instance, by arranging the weight 20 between the segment 19 and the pivot 8, turning to the right.
The stroke of the segment-lever 19 2O on the head 49 is not absolutely necessary, but it is of advantage for the timely seizure of the sheets by the y-sticks.
I claim as my invention- 1. In a platen-press, an automatic sheetfeeding device, comprising in combination with the platen 9 a plate 11 movable toward and from each other, a shaft 21 in connection with the platen 9 to move therewith, feedingarms carried by said shaft and having viscous material thereon, a toothed wheel 23 on said shaft, a pivotally-supported rack-segment 19 to mesh with the toothed wheel, a weight 2O connected with said segment, a head 49 for controlling the action of the segment, a sheetdelivering device consisting of a shaft 36, arms carried thereby, and connection for operating said shaft driven by a movable part of the machine, said connection consisting of a rack 40 and the toothed Wheel 38, the said delivery-arms moving between the feedingarms,` substantially as described.
2. In combination in a platen printing-press, the platen 9, the plate 11, the shafts 6 and 12 connected with said platen and plate respectively, means for moving the platen and plate toward and from each other, a shaft 21 moving with the platen, a segment 19 pivotally carried by the moving support of the platen, a pinion meshing with the segment, a weight 2O and a stop or head 49 for controlling the segment, substantially as described.
3. In combination in a platen printing-press, the platen 9, the plate 11, means for moving them toward and from each other; the shaft 12 upon which the plate 11 is pivotally supported, the shaft 3G, the delivery-arms carried thereby, a pinion on said shaft, a rack engaging therewith, a rod extending from said rack, the inking-roller 38, a doctor 28, a pivoted arm 34 carrying said doctor, said arm being connected with the rod vextending from the rack and a weight 31 connected to said arm and rod to move the delivery-arms backwardly, said weight being in the path of the shaft 12 to be operated thereby, substantially as described.
