DELIVERY IVIECHANISIVI FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 768,850, dated August 30, 1904.

Application filed September 18, 1903. Serial No. 173,643. (No model.)

To @ZZ 107mm, t 711,601/ concern.'

Be it known that I, Jol-1N FRANK HAAN, a citizen of the United States, residing' at Ohicago,in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Delivery Mechanisms for Printing-Presses of which the following' is a full, clear, and exact specifica-tion.

My invention relates to that type of delivery mechanisms for printing-presses in which the ily-fingers are caused to undergo their oscillatory motion by a cam. It is desirable that the time of starting of the fly-fingers from their initial or receiving' position be varied with relation to the operation of the printing mechanism in order that sheets of variousk lengths may all be placed by the deliverytapes or other means at substantially the same position on the fly-fingers.

My invention has for its primary object to provide improved and eflicient means whereby this result may be accomplished during the operation of the press without necessarily ad# justing the cam, a further object of my invention being to provide improved means for varying' the throw or extent of movement of the fly-fingers without varying their initial or starting position.

lVith these ends in view my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are attained, all as fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a side elevation of a part of a printing-press provided with my improvements. Fig. 2 is an end elevation thereof` looking' from the rig'ht in Fig. 1. Fig'. 3 is an enlarged detail section taken on the line 3 3, Fig. 4. Fig'. 4 is a similar section taken on the line 4 4, Fig. 1. Fig. 5 is a vertical detail cross-section taken on the line 5 Fig'. 6. Fig. 6 is an enlarged detail view of the worm-gear mechanism,hereinafter described, looking from the opposite side of that presented in Fig. 1; and Fig. 7 is a sectional view of the slide and standard.

1 is the frame of the printing-press of any suitable form; 2, the cam which operates the fly-fingers, mounted upon a shaft 3, as usual in the frame of the press. 4 represents the fly-fingers, 5 the iiy-iinger shaft, and 6 the pinion on said shaft, by which it is oscillated or rotated back and forth, all of which may be of the usual or any suitable construction.

Pivoted at the side of the frame 1 in any suitable way, but preferably by means of the shaft 3, is a standard 8, having a slotted guideway 9, in which is arranged a vertically-movable slide 10, which carries an antifrictionroller 11, resting continually upon the periphery of cam 2 and which causes the slide 10 to rise and fall as the cam rotates, the dwell of the cam beingso positioned that the fly-fingers 4 will remain at rest at the proper point in their arc of movement. Mounted upon the side of standard 8 by means of a pivot 7 is a pinion 12, and with this pinion engages a .rack-bar 13, secured to the slide 10 in any suitable way. The pinion 12 is of sufficient length to accommodate and engage with a second rackbar 14, arranged at an ang'le to the rack-bar 13 and engaging with the Lipper side of the pinion 12, whose pitch diameter passes substantially through the center of the shaft 3, so that should the standard 8 be oscillated or moved on its pivot 3 the pinion will merely walk along the rack-bar 14 without moving it. The rack-bar 14 is connected by rod 15 to the lower end of a lever 16, which is fulcrumed at 18 to the frame 1 or any other suitable support and carries at its upper end a segment-rack 19, engaging with pinion 6. It will thus be seen that as the slide 10 rises and falls, due to the conjoint action of the cam 2 and the usual spring for keeping roller 11 in contact with the cam, (indicated in dotted lines at 10,) the pinion 12 will be alternately rotated in opposite directions and the lever 16 thereby oscillated, causing the iiyfingers 4 to deliver the sheet from the tapes to the piling-table, and the time of starting from their initial or receiving' position will depend upon the position of the dwell of cam 2 with relation to the roller 11. Hence by oscillating the standard 8 on its pivot 3, and thereby changing the relative positions of the dwell of the cam and the roller 11, the starting time of the fiy-iingers may begaged to a nicety. As a convenient and efficient means of accompl ishing this adjustment of the standard 3 and at the same time holding the standard rigidly in position against undue oscillation I provide a segment-rack 20, which is rigidly secured to or formed on the frame 1 or any other suitable support and with which engages a worm 21, journaled in suitable brackets 22 on the sides of the standard 8 and having miter-gear connection 23 with a handwheel 24, whereby the Worm 21 may be convenicntl y rotated. For locking the standard 8 rigidly with the rack 2O as a further safeguard against accidental oscillation or vibration a clamp 25 is provided and has a stem 26 passing' through standard 8 and engaging in a nut in the form of a hand-wheel 27, arranged at the front side of the standard, so that the clamp 25 may be readily released when desired.

28 is a guide secured to the standard 8 and engaging the rack 2O for maintaining the proper relation of the standard and its connected parts with the rack 20 when the clamp 25 is released or in the event the clamp should work loose.

In order that the throw or' the fly-fingers may be varied at will Without changing or varying their starting position, the lower end of the lever 16 is provided with a curved slot 29, which is struck on an are from the center of the shaft 3 at the time when the fly-fingers are at their initial or starting position, and in this slot .works a block or slide 30, to which the rod 15 is pivoted and which block is susecptible of adjustment by a hand-screw 31, journaled on the lower end of lever 16. the block 30 beingl clamped at the desired adjustment by a second hand-screw 32. It will thus be seen that if the block 3() be raised or lowered in the slot 29 for increasing or decreasing the throw ot' lever 16 at the time when the iy-fingers are in their starting position the length of the -lever Will be altered With-- out disturbing the fingers. The screw 31 is threaded in a nut 33, swiveled on collar 34, pivoted on stem of screw 32, so thatscrew 31 may oscillate to follow the movement of slide 30 in slot 29, and the inner end. oi' screw 32 is threaded in a clamping-nut 35 and also constitutes the pivot for rod 15.

I--laving thus described my inventionwhat I claim as new therein, and desire to secure by Letters Patent, ise
