23 Claims.

The invention relates to new and useful improvements in paper counting means for newspaper printing presses, and more particularly to such improvements especially adapted for use with the fly delivery in high speed rotary presses.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized l0 and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawings:

Fig. 1 is a transverse vertical section, partly diagrammatic, showing a rotary folding-off, delivery and counting mechanism embodying the invention, a portion of it being taken on line ll of Fig. 2;

Fig. 2 is a side elevation, looking at the central part of Fig. 1 from the right, and showing also the mechanism of the other figures;

Fig. 3 is a transverse vertical section on line 3-3 of Fig. 2;

Fig. 4 is a transverse vertical section on line 44 of Fig. 2; and

Fig. 5 is a transverse vertical section on line 5-5 of Fig. 2.

Objects of the invention are to provide a simple, sturdy and smoothly-acting paper delivery and counting mechanism especially adapted for use in modern high speed rotary deliveries; to

utilize rotative movement practically throughout, and to obviate the use in cooperation of stationary parts and very rapidly moving parts, and to avoid the impact of stationary parts on independently rapidly rotating parts or articles;

to avoid all sudden and impactive actions, in

cluding such actions between stationary mechanism, or suddenly started mechanism, and rapidly rotating papers; to provide counting means rotating with the paper delivery, having its own limited, smooth and relatively slow movements while moving with the rapidly rotating fiy delivery; to provide such mechanism having only r0- tative movements; and to provide such mechanism which does not impart sudden and forceful movement to the rapidly rotating papers.

With these and other objects in view, a counting mechanism is provided which rotates with the rotating fly, and has also its own rotative movement, and is provided with a counting member which rotates with the fly and is controlled and actuated to pass into and out of operative relation with one of the fly pockets, after a predetermined number of rotations of the fly to sweep the paper from said pocket as it is about to leave the pocket and thus to indicate the count.

The present preferred embodiment comprises a kicker arm mounted upon and rotating with the rapidly rotating fly, and means for maintaining the kicker arm inactive for a predetermined number of revolutions of the fly and for then actuating it to displace a paper at delivery to mark the count in the usual manner, In said embodiment the kicker arm, mounted on the fly disc in operative relation to a paper pocket, is mounted on a spring-impelled shaft, which is held from rotation and against its spring by a detent lever. The detent lever releases the shaft, after a predetermined number of revolutions of the fly, by means of a rotated holding and release mechanism for the detent lever, which is rotated step by step on successive rotations of the fly. This comprises a cam which actuates the detent lever, the cam being fixed on a shaft which is journaled in the rotating fly mechanism; and a pawl .and ratchet mechanism also fixed on the shaft, the pawl and ratchet being advanced step by step, on successive rotations of the fly, through the agency of a stationary cam, which cam also acts to restore the kicker arm to inactive position. It will be understood that the foregoing general description and the following detailed description as well are explanatory and exemplary, but are not restrictive of the invention.

Referring now in detail to the embodiment of the invention illustrated by way of example in the accompanying drawings, a rotary transverse folder of a well-known type is shown conventionally, and includes a cylinder I having a rotatable folding blade 2 which folds off the middle of the associated sheets p into the bite of a pair of folding-off

rollers

3 and 4 in a wellknown manner. The cross-folded product p is delivered from the folding-off

rollers

3 and 4 into a rotary fly delivery, which in turn lays the folded papers on a traveling delivery belt. As here shown, the fly delivery comprises a plurality of spaced-apart, side-by-side discs I0, having hubs H mounted on and fixed to a shaft 12,

which shaft is journaled in the side frames it; on the press, and is rotated in any suitable manner. The discs it have a plurality of paper-carrying pockets i on their peripheries, the pockets being formed between shaped portions of the disc periphery and fingers or blades l5 fixed to the peripheries of the respective discs to form the exterior side of the paper-receiving pockets.

A series of spaced-apart, side-by-side stationary guides 59 are mounted on a supporting rod 28, the guides i9 being positioned in front of and in alinement with the pockets it on the corresponding delivery discs. Beneath the rotary fly is a delivery belt 23 running over rollers 24 at either end, the belt being intermittently or continuously movable as may be desired, the folded papers from the fly pocket being delivered to and laid upon the belt in stepped echelon relation in a well-known manner. Cooperating with the pockets M at the delivery point are a corresponding series of stop arms 2?, located alongside the respective fly discs and just above the delivery point of the papers from the pockets to the conveyor belt 23. The stop arms 2'! are supported in fixed position upon a transversely-disposed supporting rod 23, the lower faces 29 of the arms 27 engaging with the folded forward edge of the paper to move it out of the rotating fiy pocket and deliver it to the conveyor belt.

The paper displacing means which operates, after the delivery of a predetermined number of papers to the delivery belt, to displace a paper to indicate the count, comprises a kicker arm 37 mounted on one of the fiy discs so that, after a predetermined number of revolutions, it will kick the paper in a fly pocket to displace it for the count as it is delivered to the delivery tapes. As embodied, kicker arm 3i is fixed on a shaft 38, which shaft is rotatively journaled in a fly disc it, and is journaled at its other end in a member rotating with the disc It, shown as a disc 39 having a hub 49 fixed to the shaft i2. The shaft 38 extends beyond the disc 39 and on the projecting end of the shaft, on the other side of the disc, there is fixed an arm ll having at its end a cam roller 42. Shaft 38 is under spring impulsion to rotate in counter-clockwise direction, and is normally held against rotation by means later described. Coil spring 63 encircles shaft 3-3 between the discs l5 and 39, and tends to rotate the shaft in the counter-clockwise direction in Figs. 3 and 4, that is, the spring tends to move the arm 3'! from the dotted line to the broken line position in Fig. 4 to effect the displacement of a paper in a particular pocket to indicate the count.

Means are provided for normally holding shaft 38 against the impulsion of spring t3, and for releasing it at the proper time for displacing the predetermined paper and then restoring the mechanism. As embodied, there is fixed to shaft 38, on the inner side of the disc 39, a collar 46 having in its periphery a detent notch 41. A cooperating detent lever :38 is pivotally mounted on a pin 48, which is fixed in and projects from the disc 39. The inner end of lever 48 engages in the detent notch ll, and the outer arm 53 of lever 48 has its outer end curved to fit the periphery of earn 5? (Fig. 4), so that the cam will rotate beneath the contacting end of the lever without rocking the lever or disturbing its hold on shaft 38. Adjacent its curved end, lever arm 5!] has a curved cam surface 5i, which is engaged by a projection 56 in the periphery of cam 5?, the projection engaging the surface 5| to rock detent lever 28 from its notch 41 after a predetermined number of revolutions of the fly discs. A spring 52 is mounted on disc 39 and resiliently holds detent lever 38 in the notch 41 and thereby holds arm ll and the kicker arm against the action of spring 53.

The embodied form of means for periodically releasing the kicker arm 3? to cause it to swing past the paper pocket to displace the count indicating paper comprises a circular cam 5'1 fixed on a shaft which shaft is rotatably journaled in the end fly disc ill and in the disc 39, and is given a step-by-step angular advance on each rotation of the fly discs. On the circular periphery of cam 5V is a projection 56, which once on each rotation of the cam engages in the depression ill on lever arm 59 to rock detent lever 38 to release collar t5 and shaft 38. Shaft 58 is advanced angularly intermittently on each rotation of the fly. The shaft 58 extends through the disc 39 and fixed on the outer end of this shaft, on the opposite side of disc 39, is a ratchet wheel 59. As here embodied, the ratchet wheel has ten teeth and is advanced one tooth for each revolution of the fly, and thus the count is marked by displacing a paper on every tenth revolution of the fly. Loosely mounted on shaft 58 between disc 3t and ratchet wheel 59 is a pawl lever 6!, having a pin 62 mounted in its outer end, and a pawl 63 pivotally mounted on pin 62 engages with the teeth of the ratchet Wheel 59 and is spring-held thereto by a spring 64 in tension between the pawl and its lever. A coil spring 65 encircles the hub of lever arm GI, and its ends are connected to the pawl lever arm and to disc 39. It holds the pawl in retracted position, and its movement in that direction is limited by a spring stop pin 6 5, spring mounted on a lug fixed to and projecting from the side face of disc 39. The actuating means for the pawl and ratchet mechanism comprises a cam roller ll mounted on the pin 62 of the pawl lever, which roller coacts with a stationary cam 72. The cam 72 is shown integral with a sleeve 13, surrounding the shaft !2 and having an annular flange "M, abutting on and bolted to the machine frame l3 by a plurality of bolt and slot connections 16, which provide angular adjustment for the cam.

The manner of operation of the foregoing mechanism is as follows: In the illustrated mechanism, the fly discs have five pockets around, and the count is made on the fiftieth paper, that is, after ten revolutions of the fly mechanism. As the fiy mechanism rotates, the folded papers are delivered by the feeding-

oif rollers

3 and 4 into the fly pockets l4, and are delivered from the pockets onto the delivery tapes 23, in a known manner. At this time detent 48 holds the kicker arm 31 in its retracted or dotted line position (Figs. 3 and 4) with respect to its paper pocket Hi, and the end face of the arm 50 of the detent lever 43 is riding on the smooth periphery of cam disc 5?, which rotates intermittently without moving the detent lever. On each revolution of the fly mechanism cam roller 1| rides around stationary cam 12, and once on each revolution of the fly pawl lever 6! is rocked against its spring 85 and feeds ratchet wheel 59 forward one tooth. The ratchet wheel in this instance has ten teeth, and the ratchet wheel is advanced one tooth on each of nine successive revolutions of the fly, and during those nine revolutions the end of the detent lever is riding on the smooth periphery of cam disc 57 and the detent lever remains in the notch 41 and holds the kicker arm 31 inactive.

On the tenth revolution of the fly the projection 56 in the periphery of cam 51 enters the recess 5| in lever arm 50 and rocks the detent lever to the broken line position in Fig. 4, and thereby releases shaft 38 which under the impulsion of spring 43 is rotated in the counterclockwise direction and kicker arm 31 is moved from the dotted line position to the broken line position in Fig. 4, and displaces the paper in pocket l4 just as it is delivered to the delivery tapes 23. Arm 4|, which is fixed to shaft 38, moves with arm 31 and the movement of arm 31 is stopped when the cam. roller 42 on arm 4| engages the low part of the cam 12. As the fly continues its rotation, cam roller 42 rides up on cam I2, reversely rocks shaft 38 and brings back arm 31 from the broken line position to the dotted line position (Fig. 4), and detent lever 48 snaps into notch 41 and holds the arm 31 in inactive position until the described cycle is again repeated. Arm 4| at the same time is rocked away from cam 12 into the position shown in Fig. 3, and the kicker mechanism is held until the tenth succeeding revolution of the fly.
