SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 405,582, dated J' une 18, 1889.
Application tiled September 20, 1888.
terly, in the county of lvashington and State' of Rhode Island, have invented new-and useful Improvements in Sheet-Delivery Apparatus for Printing-h/Iachines, of which the following is a specification.
My invention relates to improvements in sheet-delivery apparatus for printing-presses; and it has for its obj ect to provide novel mechanism for preventing the printed faces of the sheets from coming in contact with parts of the apparatus during their delivery to the recei ving-table, and to deliver the sheets printed face uppermost.
The object of my invention I accomplish in the manner and by the combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a printingpress provided with my improved sheet-delivery apparatus. Fig. 2 is an end elevation of the same as seen from the left-hand side of the sheet. Fig. 3 is an end elevation, on a larger scale than the preceding gures, of the tapes and the delivery-table in their proper position on the press. Fig. 4 is a vertical longitudinal section on the same scale as Fig. 3, showing the mechanism which retains the printed sheet and which delivers the saine to the receivin g-table.
Similar letters indicate corresponding parts.
In the drawings, the letter A designates the frame of a printing-press, which frame is constructed to support the rotating impressioncylinder B and the reciprocating type-bed O in their proper relative positions. In the example shown in the drawings, Figs. l and 2, the reciprocating motion is imparted to the type-bed C by means of an ordinary rack and knuckle shaft, consisting of a spur-wheel D, arranged on a shaft Dl in a proper position to engage with a horizontal row of pins on a rack-bar D2, pendent from the type-bed O. However, other known means may be elnployed for the specified purpose.
Upon the shaft of the impression-cylinder B is mounted a cog-wheel B', which is properly connected by intermediate gears to a gear Serial No, 285,896. (No model.)
-arranged upon the driving-shaft B2 of the press, whereby the rotary motion is imparted to the impression-cylinden In a suitable cavity of the cylinder B are arranged the usual grippers B3, Fig. l, for holding the sheet to be printed upon the cylinder, these grippers lon gitudin al guideways E', which are intended I to support and guide a table, which I shall hereinafter term the delivery-table E,and this table is adapted to reciprocate so as to lie at stated intervals below tapes F, which extend around a pair of tape-rollers G G', having suitable bearings in the frame, and these tapes are in a position to receive the printed sheet from the impression-cylinder. One of these tape-rollers G is situated in close proximity to the impression-cylinder B, while the second roller G is placed at such a distance from roller G that the length of the receiving-surface formed by the tapes F, extending around the said rollers, will be fully as great, or preferably somewhat greater, than the length of the sheet to be printed.
The reciprocating motion is imparted to the delivery-table'E, in the example :shown in the drawings, by means of a suitable gearconnection with a rack C on the type-bed O. This connection consists of a gear-wheel C2, mounted on a shaft c, which has bearings in the press-frame and carries on its other end a bevel-gear O3, which meshes into a bevelgear O4, secured to a shaft c', which also has bearings in the press-frame, and on the end of this shaft c is a similar bevel-gear O5, which engages a bevel-gear C6 on the driving-shaft c2 of the delivery-table. Upon this shaft are a pair of gear-wheels C', which are properly arranged to engage with racks E2 E2 on the bottom of the delivery-table.
A continuous linear motion lin the direction indicated by arrow l in Fig. l is imparted to IOO the top tape F by rotating thc tape-roller G in the proper direction. As shown in the drawings, this rotation of the tape-roller G is accomplished by arranging a pulley7 g upon the shaft g of the said roller G, which pulley is connected, by means of a belt g2, with a pulley g3, arranged in a proper position on the shaft of the impression-cylinder B; or the said pulley g3 may be formed integral with .the gear B. The connections of the tapes F and the reciprocating delivery-table E with t-heir respective drivers are so designed that the linear velocity of the said tapes and table will be the same, this equality of speeds being necessary to secure the proper transfer of the sheet to the delivery-table E, since the said sheet is delivered to the said table during its forward stroke from under the tapes.
Itis evident that the tapes F and the reciprocating table E would form a worki ng combination, since the printed sheets would be deposited upon the said table E and by the tapes F, and could be allowed to remain on the table until a sufcientnumber had accumulated, whence they could be removed by the person in attendance; but I have found it desirable to remove each individual sheet from the delivery-table as soon as it is deposited thereon. To accomplish this purpose, I have arranged a set of grippers at the end of the frame in a proper position to retain the sheet while the delivery table moves away from the grippers and to release the sheets at the proper time. The specific construct-ion and arrangement of this mechanism are as follows: At the eXtreme end of the frame are arranged on a suitable rod a se? of stationary fingers H, Figs. 2 and 3, the ends of which are on a level slightly above that of the top of the table, so that the sheet can pass under the said fingers. Directly below these fingers H are a series of grippers H, which are secured to and can turn with a gripper-shaft 7L', having bearings in the frame. To the ends of this gripper-shaft h are secured levers H2, which are fulcrumed at h2 to the press-frame, and from each of these levers extends a rod H3, Figs. l and 4, having bearings h3 in the pressframe, and said rods are provided with dogs h4 h5, which are adapted to be engaged at certain intervals by projecting downward from the delivery-table E. The dogs hA1 h5 upon the rods are placed at such a distance apart and in such position upon the rods H3 that shortly before the delivery-table stops in its travel toward the impression-cylinder the post e on the said table engages the dogs h5 on the rod H3 and opens the grippers H. On the return motion of the receiving-table toward the grippers, and directly after the forward end of the sheet projects into the grippersfthe post e engages the dogs h4 and the grippers close upon the sheet, and on the return motion of the delivery-table they are again opened, as before described, and release the sheet, which then falls upon a receivingtable I, situated in a proper position to re- -the sheet-guide shaft. imparted to cam-shaf t J 3 by means of a gear ceive the said sheet. To allow the grippers to obtain a hold on the sheet without the necessity of having the latter projecting beyond the delivery-table, I cut slots e in the proper end of the table, into which slots the grippers proj ect.
To facilitate the delivery of the sheet from the impression-cylinder B upon the tapes F, I employ sheet-guides J, which are arranged upon a shaft J extending between the said cylinders and the tape-roller G, and which sheet-guides are actuated by a cam J2 on a shaft J 3, which cam engages with a roller-stud J 4, arranged on the end of a lever J 5, secured to A rotary motion is J6, which meshes into a gear Bu1 on the slotshaft of the impression-cylinder B.
In the position shown in the drawings the press has just finished printing a sheet. The type-bed is on its back-center, and the delivery-table E is in extreme forward position toward the grippers H, and a printed sheet on the said table is under the said grippers, while the front edge of the sheet just printed is under the grippers of the impression-cylinder B. apparatus is n ow as follows: When the typebed starts on its return toward the impression-cylinder,the delivery-table E participates in its motion in the same direction,and when the type-bed is at the other end of its stroke the delivery-table will have advanced to the end of its course and will be in the position shown by the single dotted line o: in Fig. 1- that is to say, will be directly under the tape F. During the time thus elapsing the printed sheet will have been advanced outward upon the tapes, and by the time the type-bed reverses and starts toward the forward end of the press the sheet will lie with its advanced edge directly in a vertical line about the edge of the table, facing the grippers H. Now, when the type-bed continues in its motion toward the forward end of the press, the delivery-table travels in the same direction and the printed sheet is fed upon the said table from the tapes. During the previously-described motion of the deliverytable in the direction toward the impressioncylinder the same has engaged with the lever-rod H3 and opened the gripper H, and the same remains open until it is closed by the table acting on dogs h4, whence it closes upon the sheet and retains the same while the table moves in the direction of the arrow 2, marked thereon, until the free end of the sheet clears the delivery-table, whence the grippers are opened by the action of the table upon dogs h5, whereupon the grippers open and release the paper, which then falls upon the table printed side up. This completes the operations, and the sheet is delivered without having its printed face brought into contact with any part of the apparatus.
Vha-t I claim as new, and desire to secure by Letters Patent, is-
The operation of the sheet-delivery IOO IIO
l. The combination, with the impressioncylinder of a printing-press, of the traveling tapes F,receiving the printed sheet from the cylinder, the delivery-table E, reciprocating independently of and back and forth below the tapes, and on its forward movement receiving the printed sheet from the forward portion of the tapes, and a receiving-table I, for receiving the sheet from the deliverytable, substantially as described.
