JAMES BENGOUGH, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO THE OARTER-CRUME CO., LIMITED, OF NIAGARA FALLS, NEW YORK, A CORPORATION OF CANADA.

DELIVERY MECHANISM FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, JAMES BENGOUGI-I, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Delivery Mechanism for Printing-Presses, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to printing mechanism, and one of the objects thereof is to provide improved means for ejecting one or more sheets from the accumulating table of a printing press.

Another object of the invention is to provide mechanism of the above character adapted for use with plate presses, which will be simple in construction and entirely reliable in action.

A further object of the invention is to provide means whereby a predetermined number of printed sheets may be carried from the accumulating table of a printing press, of such construction as will in no wise interfere with the delivery of fresh sheets upon said table.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is illustrated one of the various possible embodiments of my invention, Figure 1 is a top plan view thereof, the accumulating table being removed in order better to illustrate certain operative parts thereof, said view being taken substantially on line att, Fig. 2. In this figure the relative positions of the slots in the accumulating table through which the ejector fingers pass are indicated diagrammatically by dotted lines. Fig. 2 is a vertical sectional view taken substantially on line Z)b, Fig. 1; Fig. 3 is a vertical sec tional view taken through a portion of the delivery table and the carriage upon which the ejecting devices are mounted, showing the means for tripping the ejecting devices into position to engage with the sheets upon Specification of Letters Patent.

Application filed September 25, 1906.

Patented May 16, 1911.

Serial No. 336,142.

the table; Fig. 4 is a similar view, but showing the parts at the end of the forward movement of the carriage; Fig. 5 is a view in perspective of the traveling carriage and the ejecting means mounted thereon.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to the drawings, wherein I have shown an embodiment of my invention arranged for use with a plate printing press, 1 indicates a platform or table upon which sheets 2 are delivered from the printing mechanism. Inasmuch as the printing mechanism forms no part of my present invention, the same has been omitted from the drawings, it being understood that the table 1 is relatively so located with respect thereto as to receive the sheets therefrom immediately after having been acted upon by the printing devices. The sheets are superposed one upon another upon the table, as shown in Figs. 3 and 4 of the drawings, and at this point it may be noted that the mechanism as disclosed herein is adapted to deliver the sheets in such superposed relation in order that they are readily fastened or bound together in book or tablet form. Table 1 is provided with a plurality of longitudinally extending slots 3 through which the ejecting means are projected at regular intervals into position to engage and carry the sheets therefrom, as will presently be described.

Upon a pair of rods 4.- extending in parallel relation with slots 3 and suitably supported in the framework of the machine beneath table 1 is a carriage '5. This carriage is loosely mounted upon said rods and is adapted to slide forward and backward thereon. Journaled in upward extensions 6 of carriage 5 is a shaft 7 having affixed thereto at regular intervals a plurality of ejector fingers 8. One of these ejector fingers is arranged beneath each of the slots of the accumulating table and said fingers, when shaft 7 is rotated, are adapted to be projected through said slots into position to engage with the sheets thereon. The means for swinging said fingers through slots 3 comprise a pair of springs 9 which are coiled about shaft 7 and are attached at their outer ends thereto, said springs having their opposite ends fast in said carriage. These springs are tensioned so as constantly to urge fingers 8 to an upright position, which fingers are normally held against the ten sion of said springs in inoperative position beneath the table by means of a trigger 10 pivotally mounted upon carriage 5 which engages a shoulder or ledge 11 of a collar 12 fixedly mounted upon shaft 7. Collar 12 is also provided with a second shoulder or ledge 13 which engages trigger 10, such engagement limiting the rotative movement of shaft 7 and holding fingers 8 in an upright position through slots 3 of table 1 in position to engage the sheets thereon.

A cam 14 is secured, as by means of screw 15, to the framework beneath the table in position to engage a cam surface provided upon trigger 10 when carriage 5 has been moved to initial position and thereby trip said trigger to release ejector fingers 8, and said ejector fingers are retracted through slots 3 into inoperative position beneath said table at the end of the forward movement of the carriage, by means of cam ledges 16 formed integral with said table and located underneath the same at the forward ends of slots 3. These ledges engage the fingers during the forward movement of the carriage and depress the same to such position as will enable trigger 10 to take behind ledge 11, as clearly shown in Fig. 4 of the drawmgs.

The carriage is slid forward and backward on rods 1- by means of a lever 17 provided at its outer end with an elongated slot the walls of which take about a stud 18 which extends downward from carriage 5, said stud being threaded at its end to receive a nut 19 which holds said lever in position thereon. Lever 17 is pivotally mounted upon a stud 19 which extends downwardly from a lateral extension of table 1 and is normally urged to swing in one direction by means of a spring 20 which is coiled about said stud and has one end secured to said lever, the other end thereof being secured to the lateral extension of the table. The opposite end of lever 17 is provided with a stud 21 which is adapted to ride upon the periphery of a wiper-wheel 22 ournaled upon a stud shaft which projects downwardly from table 1. Secured to wiper-wheel 22 is a ratchet wheel 21 adapted to be engaged and rotated by a pawl or dog 25 pivoted upon a lever 26 journaled upon stud shaft 23, the outer end of said lever being pivotally connected to a link 27 which is, in turn, pivotally connected to a link 28 adapted to be reoiprocated by any suitable mechanism driven from the printing mechanism. The cammed periphery of wiper-wheel 22 is provided with an abrupt step or shoulder, as at 29, so that when stud 21 of lever 17 has been traversed by the periphery of said cammed portion, the same will reach step 29 and be permitted to swing under the influence of spring 20 to the position shown in dotted lines in Fig. 1, and, as a means for arresting this movement of lever 17, I provide a shoulder 30 upon a link 31 resiliently suspended by means of a spring 32 in the framework of the machine, the lower end of said link being slotted to take about studshaft 23 upon which the wiperwheel is j ournaled. This stud forms a guide for link 31 and prevents the same from relative lateral movement. A holding pawl 33 is mounted upon a stud 34 extending downwardly from the table which engages ratchet wheel 2st and prevents a reverse movement thereof.

Having described this embodiment of my invention, the operation thereof may now be understood. It may, however, first be noted that sheets which have been acted upon by the printing mechanism are deposited or piled one upon another on table 1 and that the number of teeth upon ratchet wheel 2 1 corresponds to the number of sheets which are to be collectively ejected from the table at a single operation, it being understood that the said ratchet wheel is rotated by means of its actuating mechanism through the space of one tooth at each printing operation of the press. The rotation of ratchet wheel 21 will, through wiper-wheel 22, cause a swinging movement of lever 17 against the tension of spring 20, which will move carriage 5 and the ejecting fingers carried thereon from the position shown in dotted lines in Fig. 1 to the position shown in full lines in said figure, and immediately preceding the end of this movement cam 14 will trip trigger 10, whereupon springs 9 will swing fingers 8 through the slots of table 1, as shown in Figs. 2 and 3. During this recovery movement of carriage 5 a predetermined number of sheets will have been deposited upon the table ready to be ejected therefrom, as shown in Fig. 3. At this point of the operation of the machine, stud 21 of lever 17 is about to escape step 29 and swing down against shoulder 30 of link 31, inasmuch as wiper-wheel 12 has been rotated to substantially the position shown in Fig. 1 of the drawings, and, when such swinging movement of lever 17 occurs, carriage 5 will be projected forward rapidly and fingers 8 which are in engagement with the pile of sheets upon said table will carry the same therefrom, leaving the table free to receive fresh sheets from the printing mechanism. The engagement of ledges 16 of table 1 with fingers 8, as above described, will depress them to the position shown in Fig. 4, whereupon trigger 10 will again engage the shoulder 13 of collar 12 and hold said trigger in inoperative position beneath the table during the recovery movement of the carriage.

The above-described operation takes place automatically during the operation of the press and at each forward movement of the carriage a predetermined number of sheets are ejected from the accumulating table, fresh sheets being deposited upon said table during the backward or recovery movement thereof.

It will thus be seen that I have provided mechanism well adapted to attain the ends and objects of my invention and that the same, while of simple construction, is characterized by accuracy of action.

l/Vhile I have shown my invention as applied to a press of the plate type, it will be understood that it may be adapted to other forms of presses, although the same is of peculiar value in the relation shown.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
