NEWSPAPER COUNTING APPARATUS Filed NOV. 9, 1937 2 Sheets-Sheet 2 jwer-czav K/ldrZe-SFJQ I Patented Aug. 16, 1938 UNITED STATES PATENT OFFICE 7 Claims.-

This invention relates to improved apparatus for counting articles such as newspapers being delivered from a printing press. The present invention affords a simple, inexpensive mechanism for this purpose which is adapted to compensate for variable conditions which may occur during the operation of the press and the conveyor associated therewith so that an accurate count may be afiorded under all operating conditions. While the apparatus is particularly adapted to operate a counter which may be observed to determine the number of papers which have been printed and which have passed along the conveyor, it may also be associated, if desired, with automatic mechanism for interrupting the press after a predetermined number of copies of the papers have passed along the conveyor.

The apparatus is furthermore arranged so that it may only count alternate papers or alternate paper sections and, furthermore, the device may be arranged so that only every third or fourth paper or the like will be counted. Such an arrangement is particularly advantageous when the paper is being printed in separate sections individually delivered to the fan which forms a portion of the conveying means.

In the accompanying drawings:

Fig. '7 is a wiring diagram, with parts schematically shown.

In Fig. 1 I have diagrammatically disclosed conveying means which is associated with a press and folder in the conventional manner. Papers are delivered from the folder, 2. portion of which is indicated by the numeral I, to a delivery fan 9 having a plurality of blades l2 separating the peripheral zone of the fan into a plurality of pockets, each of which may receive a single folded paper or a single section of a paper, if the paper 50 is being printed in a plurality of sections. For purposes of convenience of description, the paper received by a single section of the folder, whether in the form of a section of a newspaper or in the form of the entire newspaper, will hereinafter be referred to as a paper.

The delivery fan 9 is rotated in synchronism with the remainder of the conveyor means H which includes a horizontal run I 2 and a vertical run l3, the fan delivering the papers in overlapping relation onto the horizontal run l2 which 5 in turn supplies the papers to the vertical run 53 from which the papers may pass to the mailing room or the like. The folder l and the conveyor II are driven while the press is operating and, in some cases, continue to operate when the press 10 is no longer operating in order to clear the entire apparatus of printed papers.

Since the folder I and conveying means, including the conveyor 1 l and delivery fan 9, are operable in synchronism, and since the delivery 15 fan can only deliver a certain maximum number of papers corresponding to the number of pockets which pass below the folder I in a given period of time, it is evident that a counter driven directly in synchronism with the conveyor would afford an accurate count, if papers were continuously supplied to the fan and conveyor during this entire period of operation. As a practical matter, there are interruptions in the stream of papers supplied from the folder to the conveying means, so that such an arrangement by itself would be unsatisfactory. On the other hand, the operation of the counter by the conveying means avoids inaccuracies due to the movement of the papers out of normal overlapping relation. Accordingly, I provide means normally operating the counter in response to the conveying means but provided with a controller to interrupt such operation when there is a gap in the stream of papers passing along the conveyor. Thus an accurate count may be afforded by a relatively simple mechanism.

For this purpose I provide a circuit-closing means 20 operable in synchronism with the conveyor II and driven by suitable means such as a chain 2] from a portion of the conveyor. This circuit-closing device is arranged so that it may always be driven when the conveying means is operating. The device is electrically connected through a suitable controller 26 to an electrically'actuable counter 21. The controller conditions the electric circuit so that impulses may pass from the circuit-closing means 20 to the counter as long as a stream of papers is passing the controller 26. Whenever this stream of papers is interrupted, there is a corresponding interruption in the electrical circuit and, although the circuit-closing means 20 continues to be driven by the conveyor, electrical impulses are no longer transmitted to the counter. Figs. 5 and 6 illustrate in detail a preferred )55 form of circuit-closing means. The chain 2| drives a shaft 30 through a sprocket 3|. This shaft extends into a casing 32, and suitable cam means 33 is disposed within the casing and secured to the shaft. In the illustrated form of the invention such cam means comprises two noncircular cams 34 of insulating material. For example, as shown, each of these cams may be substantially square. Two leaf springs 25 are mounted on an insulating block 36 at one end of the housing and carry electrical contacts 25* and 25 at their opposite ends. The mid-portions of these springs are engageable by the corners or lobes of the earns 34; accordingly each time that a spring 25 is actuated by a lobe of the corresponding cam, the contact at the end of the spring is moved away from contact on a common metal plate 38 which is mounted on an insulating block 38 It is evident that with the form of the invention illustrated, a single rotation of the shaft 39 may be effective in causing eight circuit opening and closing movements of the springs 25 and the corresponding contacts, 25 and 25 these eight movements corresponding to the eight pockets in fan 9. Thus this assembly may be operable to send eight electrical impulses along the electrical circuit during each revolution of the fan.

Preferably the cams 33 are secured to the shaft 39 by suitable set screws 46 so that the cams may be removed or adjusted. If desired, either of the cams 33 may be removed and other cams having a different number of lobes may be substituted for either one or both of these cams so that, instead of counting every paper section or eight papers for each revolution of the shaft 39, the device may be adjusted sothat it may either count every alternate paper, every third paper, every fourth paper, etc. Obviously the sizes of the sprockets associated with chain 2| may also be changed, if desired, to permit variation in the ratio between the number of impulses and the number of papers passing along the conveyor.

If a continuous stream of papers were always supplied to the conveyor, the timer shown in Figs. and 6 could be employed directly without further apparatus to control the counter 21 to assure an accurate count. However, since there actually are gaps in the stream of papers passing along the conveyor, 1 have provided the controller 26. This controller includes a casing 56 supporting insulating blocks 5|: (Figs. 3 and 4) on its inner wall. Each of these blocks carries a fixed contact 52 and a leaf spring 54 carrying a movable contact 55 engageable with the corresponding fixed contact 52.

On the lower part of the casing is mounted a shaft 51 and a sleeve 58 adapted to turn on the shaft. Arms 59 and 60 are disposed within the casing 56 and are connected respectively to the shaft 51 and the sleeve 58. On the outside of the casing the shaft 51 carries an arm 6| and sleeve 58 carries an arm 62. The extremities of these arms support contact rolls 64 and 65, respectively. These rolls are arranged to contact the papers passing along the escalator or vertical run |3 of the conveyor Accordingly, when the first paper of a group comes along a conveyor, its advance edge first engages the contact roll 65, swinging the arm 6| toward the casing 56, and as the paper continues on its path, the roll 64 and the arm 62 are also moved toward the casing 59. The rolls 64 and 65 are spaced from each other at a distance along the conveyor somewhat less than the width of the folded paper for a purpose that will be more fully described.

The arms 59 and 60 have slotted ends which receive the ends of pins 19 and 1| respectively on lugs 12 and 13 respectively, fixed to slidable rods 14 and 15. These rods are yieldably urged toward the position shown in Fig. 4 by springs 16, the movement of each rod in this direction being limited by a collar 19 engageable with the wall of the casing 50. When the arms 62 and 6| are swung toward the casing 59 by a paper passing along the conveyor, the shaft 51 and sleeve 58 are turned so as to swing the upper ends of arms 59 and 69 toward the block 5|. The springs. 54 carry rods 80 with plates 8| and B2 of insulating material engageable with the lugs 12 and 13 respectively, so that as the arms 59 and 66 are moved in this manner toward blocks 5|, the springs 54 may be effective in moving the contacts 55 into engagement with the corresponding contacts 52. Obviously both sets of contacts only continue in engagement while both arms 6| and 62 are swung away from the conveyor and toward the casing 40. As soon as, for example, the arm 6| swings away from the controller, after a paper has passed the roll 65, the corresponding arm 59 moves away from the block 5|, acting through the corresponding plate 8| and rod 80 to permit the corresponding contact 55 to separate from the contact 52.

Obviously the arms 59 and 66 may swing toward the plates 5| to a position substantially beyond that required to close the corresponding switches provided by contacts 52 and 55. Thus an arrangement is provided to permit suitable ranges of movement for the exterior arms 6| and 62, so that the latter may move inwardly only a slight distance when, for example, one paper comes along the conveyor but yet may be thus eifective in closing the switches within the controller casing 59. On the other hand, the arms 69 and 6| may move inwardly a substantial distance when a plurality of relatively thick overlapping papers are passing along the conveyor. Under such conditions the springs 16 permit the arms 59 and 66 to swing through a substantial angle while the switches 5255 are held closed by springs 54.

The operation of the apparatus may best be described with reference to the Wiring diagram of Fig. '1. Current is supplied from a suitable source to leads BI and 82, the latter being connected directly to the conventional actuating mechanism of the counter 21. From this mechanism a lead 83 may extend to one of the contacts 52, as that associated with the shorter arms 59 and 6| of the controller 26. From the corresponding contact 55 a lead 86 extends to the other fixed contact 52, while a lead 85 extends from the corresponding movable contact 55 to the contact plate 38. The latter has electrically conductive portions engageable by each of the contacts 25 and 25 carried by the leaf springs 25 of the circuit-closing means 26, which are alternately moved into circuit-closing position by the cam means 33. One spring 25 which is associated with one of the cams may be connected directly to the lead 8| extending from the source of current supply, while the other spring arm 25 may be con nected to lead 8| through a switch 89.

When the conveyor is operating, the circuitclosing means, including the shaft 30 and cam means 33, is being constantly driven. Accordingly the contacts 25 and 25 are moved to circuitclosing position to afford, for example, eight circuit-closing movements during each revolution of the shaft 30. These movements have no effect upon the counter 27 until a paper comes along the conveyor and engages the rolls 55 and 64. As the first paper engages the roll 55, one set of contacts 55 and 52 are engaged, but until the paper reaches the roll 64, the other set of contacts 52-55 remain in spaced relation so that the circuit is not yet conditioned for the transmittal of an impulse to the counter. When, however, the advance edge of the paper actuates the roll 64 and arm 62, the other set of contacts 52-55 are also engaged so that the circuit is completedand an impulse resulting from the closing of the circuit by the means 20 may then be transmitted to the counter 2'! to cause a single actuation of the latter.

If but a single paper comes along the conveyor in this manner, the roll 65 will move away from the housing 50 as the edge of the paper passes out of engagement with the roll. Thus the switch 55-52 associated with arms 61 and 59 will be opened before a second impulse can be transmitted to the counter 21. It is thus evident that the rolls 64 and 65 are spaced along the conveyor at a distance nearly as great as the width of a paper, so that but a single impulse can be transmitted to the counter while both rolls are in engagement with the paper. In practice the exact spacing of the rolls 64 and 65 can be adjusted relative to the axis of the shaft 51 and sleeve 58; thus the effective lengths of the arms GI and 62 may be varied after loosening the set screws associated with the inner ends of these arms.

When a plurality of papers move along in con ventional overlapping engagement, the rolls 64 and 85 are maintained in their circuit-closing positions, thus permitting the transmittal of a plurality of impulses to the counter, the impulses corresponding in number to the number of papers which move along the conveyor.

Should a gap occur in the stream of papers moving along the conveyor, corresponding, for example, to a failure to fill several pockets of fan 9 with papers, one or the other of the rolls will momentarily move from its circuit-closing position, causing a corresponding interruption in the transmittal of impulses to the counter. The spacing of the rolls 64 and 65 is so determined that when a plurality of overlapping papers move along the conveyor one impulse is transmitted to the counter 27 for each paper. Thus an accurate count is afforded corresponding to the exact number of overlapping papers, while, when there is a gap between successive groups of overlapping papers, impulses no longer can be transmitted to the counter 27 from the circuit-closing means 20. The spacing of the rolls 54 and 65 permits an accurate count which would not be possible were but a single contact roll employed in a corresponding location.

- The provision of the switch 89 affords convenient means permitting the transmittal of impulses to the counter in response only to alternate papers or paper sections, since, when this switch is opened, only the contact 25 is effective in sending impulses to the counter, while when the switch is closed the contact 25 is also similarly eifective.

It is evident that the present invention afiords a simple and dependable mechanism for counting newspapers or the like being received from a press and folder, the device being primarily operable in direct response to the operation of the conveyor but being provided with control means to prevent such operation from being effective to cause actuation of the counter when there is a gap in the stream of papers passing along the conveyor.
