J'OGGER FOR PRINTING-PRESSES,

Specification of Letters Patent.

. Patented Dec. 8, 1908.

Application filed. February 3, 1908. Serial No. 414,144.

To all whom it may concern:

Be it known that I, JOHN H. SToNnMnTz, a citizen of the United States, residing at Grand Haven, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Joggers for Printing-Presses, of which the following is a specification.

My invention relates to improvements in joggers for use upon printing presses, and its objects are: First, to provide a jogger that will cause the paper to assume directly vertical piles with all edges even, and, second, to so arrange a jogger for printing presses that the action of the fly fingers and shaft when carrying the several sheets of paper from the impression roll to the jogger will actuate the jogger. arms to open the wings and allow the paper to fall from the fly fingers to its proper place between the jogger wings. I attain these objects by the mechanism illustrated in the accompanying drawing in which Figure l is a top plan of a jogger board with the cap removed to show the arrangement of the several arms and their actuating pins, and, with the fly fingers in place for delivering a paper to the jogger. Fig. 2 is a top plan of the board with the fly fingers and the jogger arms removed and showing an actuating spring connected directly with the actuating disk. Fig. 3 is a section of the board on the line in m of Fig. 1, showing the disk unbroken. Figs. 4 and 5 are side views of the jogger board and fly fingers showing modified forms of attachments for actuating the jogger arms.

Similar letters refer to similar parts throughout the several views. 7

The jogger is made up of the supporting board A which has a receptacle a made in it for the reception of the disk E, a shallower receptacle, a, for the reception of the cap a, and slots F F for the reception and free action of the arms D, D, D" and D, which are formed, arranged and operated as follows: Each of these arms has a right angled projection at the inner end that is provided with a short slot cl, designed to engage the several pins 6 that project upward from the upper surface of the disk E, so that this disk, turning upon the pivotal pin 6, will draw the arms D, &c., toward the disk or force them from the disk, as desired.

The arm D is so arranged that the movement of the shaft B to carry the fly fingers C from the position indicated by the dotted lines to that shown by the solid lines will draw the arm endwise, and its action upon the disk will cause all of the arms to move endwise in the proper direction to cause the several wings d to recede from the disk and provide suflicient space between these wings to allow the fingers to place the several sheets of paper safely within the square formed by the several wings. This result is brought about as follows: The fly shaft B is, as is perfectly understood, ournaled in bearings that are supported upon the printing press frame, not here shown, and the most desirable form of actuating mechanism is constructed with an eccentric H upon the shaft B and a bell crank I pivotally connected with the jogger board A, as shown in Fig. 8, so arranged that when the fly fingers C are thrown over to the position indicated by the solid lines in Fig. 3 the eccentric H will press down on the horizontal arm of the bell crank I, forcing it downward and the vertical arm of this crank back from the board A thus forcing the arm D endwise in the same direction, and this arm, engaging its pin 6 on the disk IE, will force the disk to oscillate sufficiently to move each of the other arms from the disk and thus increase the size of the square formed by the wings 0Z so that there will be plenty of room between them to freely receive the paper from the fly fingers O, as hereinbefore suggested. The same result may be attained by the use of an actuating arm H, on the shaft B and a resistance arm I on the arm D, as shown in Fig. 4, or the bell crank I may be dispensed with and a strap I attached to the eccentric H and to the arm D, as indicated in Fig. 5, or any other available means for moving the arm D may be used.

Having provided for enlarging the square formed by the wings cl, the accomplishment of which may be by rigid, arbitrary movement, I must provide for lessening this square by an easy, flexible process, and for this purpose I prefer the use of an easy flexible spring applied in the most available manner, and have shown several applications of springs, each equally available with the other. In Fig. l I have shown a plain flat spring Gr acting upon a resistance post 9 that is secured to the under surface of the arm D, and in Fig. 3 I have shown this reinforced by an auxiliary spring G, though either of these springs may be used without the other if they are found to be strong enough to properly actuate the disk E. In Fig. 2 I have shown a coiled or spiral spring connected by the pin g tothe disk E and by the pin g to the board A, so that the disk E is actuated by it independent of the arm D. By this arrangement the wings up on the arms D and D moving crosswise of the board A, and the wings on the arms D and D, moving lengthwise of the board A are made to approach or recede from each other uni formly and at the same time. When the spring G is used it may be made of sufiicient strength so that no auxiliary spring will be needed, and, in fact, either of the springsshown, or of several forms of springs may be used with equally good eifect. The need for using a flexible means for actuating the arms D, &c., to draw the wings cl together arises from the fact that it is nec-' essary to move the thin sheets of paper very carefully until they have assumed the desired position on the pile of paper, indicated at c in Fig. 4:, and, when the paper has been made to assume this position the wings d must hold the pile firmly to place until another sheet has been placed upon it, and this, too, without pressing too heavily against the edges of the paper, or, in other words, the wings must stop moving when the desired pressure is attained, which would be impossible if the disk E was made to oscillate in both directions by the same mechanism that causes the wings d to recede from each other, unassisted by some flexible agent that would allow the arms D, D, &c., to stop at the desired and proper time.

The several arms, D, &c., are provided with a short slot near the inner end, in position to slide over the central pin e that supports the disk E.

I have shown the fly shaft B and fingers G simply as one of the many devices for delivering the printed papers from the impression cylinder of a printing press to the jogger board A, and not designed to be included as any portion of my present invention, as any of the commonly used devices for this purpose will answer as well for delivering the paper to the jogger.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is:

1. In combination with the finger shaft and delivering mechanism of a printing press, a jogger board having a central recess and grooves radiating therefrom, a stationary pin projecting upward from the center of the recess, a disk centrally pivoted on said pin and having pins projecting upward from its surface near the outer edge of the disk, arms secured in the grooves and having longitudinal slots in one end in position to receive the center pin, and lateral slots in position to receive the outer pins on the disk, a bell crank for actuating the arms one way, a spring for actuating them the other way, and a lug on the finger shaft to actuate the bell crank.

2. In combination with the finger shaft and delivering mechanism of a printing press, a jogger board having a central recess and grooves radiating therefrom, a stationary pin projecting upward from the center of the recess, longitudinally movable arms in the grooves, having longitudinal slot-s in one end in position to receive the central pin, and lateral slots at right angles therewith, a disk pivotally supported on the pin in the recess, pins projecting upward from the disk some distance from the center and in position to engage the lateral slots in the arms, and means in connection with the finger shaft and the jogger board, for actuating the arms lengthwise.
