lhis invention relates to a device for actuating a counter, for example, of the electrically operable type, in response to a series of articles moving past the device upon a conveyor. This device is particularly suitable for the accurate counting of newspapers as they leave the printmg press.

In the conventional operation of newspaper printing establishments, the freshly printed papers are delivered from the press room to the mailing or distributing room by means of a conveyor and the papers received from the conveyor are counted in the mailing room. However, papers often are removed when they leave the presses so that the number of impressions recorded in the press room may vary rather widely from the number of papers actually received in the mailing room. This invention affords an automatically operable arrangement to assure the accurate counting of the newspapers or the like as they are being conveyed from the press room to the mailing room, thus affording a definite, impartial record of the actual number of papers supplied to the mailing room by the press room and permitting the checking of the record of the number of impressions by the presses with the number of papers actually received, so that it may be ascertained whether or not an undue number of spoiled papers have been removed in the press room or whether copies of the papers have been removed by people having access to the press room rather than passing out through legitimate channels.

In accordance with this invention, I provide a device which is adapted to be actuated by the folded portion of a newspaper even when a plurality of papers pass along the conveying means in overlapped relationship to each other. This device affords suitable electrical means for actuating an electrical counter which may be of customary design and responsive to an electrical impulse. To this end, I afford two elements juxtaposed to the path of the successive papers, the first of these elements being actuable to close a controlling circuit which conditions a circuit through which the counter may be actuated, and the second of these elements actuating a switch control which causes subsequent deenergization of the counter circuit, thus affording means operable to close and open the counter circuit in rapid succession if necessary so that papers even in close overlapped relationship may actuate the counter to afiord an accurate record of the actual number of papers passing along the conveyor means.

In the accompanying drawings:

In the accompanying drawings, the numeral I designates conveyor means of the well known type which is employed in newspaper publishing establishments and which is provided with yieldable belt elements 2 passing over rollers, one of which is identified by numeral 3. The actuating device, which more particularly forms the subject matter of the present invention, is juxtaposed to such a roller 3 of conveyor I and comprises a fixed base 5 provided with a box-like sheet metal cover 6. Integral with the base 5 is an upstanding partition or plate I, while at the opposite end of the plate 5 I provide an upstanding flange 9. A pair of horizontal bars I6 extend between the lower part of plate 1 and the flange 9 to provide a track upon which a moving switch assembly II is mounted. This assembly comprises a lower platform I2 with depending lugs I3 and I4 slidably engaging the respective horizontal bars ID.

A cable 16 is secured to one end of the platform I2 and is wound about a spring operated roller II, the latter being mounted on a substantially semi-cylindrical casing 20 secured to the plate I. The spring roller I1 is arranged to draw the cable l6 and the assembly II to the right as viewed in Fig. 1, i. e., in the direction of the conveyor l. Mounted upon the platform I2 is an 5 insulating block 22 from which a tube or sleeve 2| projects through casing 6; the outer end of this sleeve carries a bifurcated metal block 23. Upon the outer end of the block 23 is a rotary element or roller 24 adapted to contact a paper 5 passing along conveyor i. Depending from the U-shaped member 23 is an integral bar 29 carrying a pintle element 25 upon which a U-shaped arm 26 is pivotally connected. This U-shaped arm 26 has its longer leg pivoted to the part 29 and its shorter leg provided with an upstanding extension 3| which projects between the legs of the bifurcated block 23.

Pivotally mounted upon the member 26 adjoining the juncture of its shorter leg with the projection 3!. is an upstanding plate 34 which also extends upwardly between the legs of member 23. The member 34 is pivotally connected, as designated by numeral 35, to a bolt element 35 which extends through an opening in the upper end of member 3!. A coiled compression spring 38 is disposed about the shank of member 25 and between a washer engaging the face of member'3l and a washer 32 which is adjustably held on the bolt element by a nut 39. Within the sleeve 2! is an actuating rod 4|, the-end portion of which extends through an opening'in extension 3| and engages the face of member 36. A

roller 26 is mounted substantially at the juncture of the legs of theU-shaped member 26, and is smaller than the roller 24, roller 46 also being engageable with papers passing along the conveyor I.

As shown in 'Fig. 3, the sleeve 2! is adjustably connected to the movable assembly I l, a block 59 projecting upwardly from the platform i2 and providing an opening to receive the end of the sleeve, and a set screw 52 being provided to clamp the sleeve 2! in the desired position in relation to the block 59. The actuating rod 4| projects beyond the end of sleeve 2| and is received within a recess in a clevis element 53 Which is pivotally connected to a crank arm 52 fixed to a shaft 55 extending through the insulating block .22. Suitable journals 56a are provided upon the platform I2 to support the shaft 55. Fixed to the shaft 55 is ametal arm 56 which is connected to a tension spring 51 that in turn is secured to the block 22 while a spring 58 connects arm 54 and block 553. These springs tend to swing arms 56 and 52 together with shaft 55 in the direction of conveyor l.

Pivotally mounted upon the shaft 55 but freely movable in relation thereto is an insulating bar 6i whichsupports a metal armature element A spring 66 tends to swing bar 6! against arm 56. An electromagnet "65 is mounted on the insulating block 22 adjoining the armature 62. For this purpose an L-shaped metal bracket i3? is provided so that its end is juxtaposed to the lower end of armature 62 to permit substantial completion of the magnetic circuit. The upper end of arm 56 receives a screw element 15] in threaded engagement therewith, this element carrying an insulating tip H and being provided with a knurled head 12. A look nut 13 is afforded to permit loosening ofthe screw in relation to the arm 56 and its ready adjustment by means of the knurled head 12.

A swinging switch arm 75 is pivotally mounted upon but insulated from a lug integral with platform I2 and has its upper end engageable with the tip ll of screw Hi. The arm 15 carries one contact of a magnet control switch J, the other contact of which is secured to the insulating block 22, the spring ll normally holding this switch closed. The upper end of the swinging insulating block similarly carries one contact of a counter-actuating switch assembly I, the

other contact of which is fixedly mounted on block 22.

Upon the upper corner of block 22 I provide one contact Bil of a'primary switch assembly K,

the opposite contact of which is mounted upon a 5 rocker 8|, the intermediate part of the latter being pivotally connected to the block 22. A compression spring 83 between the lower end of rocker 8! and the end of block 22 tends to hold the contacts of switch K in mutual engagement, while a screw 85, having an insulating tip 82, is engageable with the lower end of rocker 8i to compress spring 83 and thus move the contacts out of engagement, see Fig. 1. The screw 25 is threaded through an opening in plate 7 and-is also provided with a knurled head 86 and a lock nut 81.

As .shownin Fig. 4, a plurality, namely three, resilient metal fingers or contact elements 9E, 92 and 93 are secured to an insulating plate 26a mounted upon the upper part of block these elements engage "corresponding contact bars 92, 95 and 2'5 which are secured upon the lower su face of a fixed insulating plate 99 that projects fromthe-upper end of plate '5.

The arrangement of the electrical connections of my device and of the associated counter be more readily understood by having reference to Fig. 5 wherein the counter, which may be of the customary type operable in response to electrical impulses, is designated by numeral I22. A lead ilii connects the counter to one side of the source of electrical supply for example, to an ordinary lighting circuit. A branch 892 of this lead is connected to the fixed bar 25 which contacts the metal element 93 upon assembly H. The member 93 is connected by a lead 624 with the contact of switch assembly J which is carried by arm 15. The opposite side of the electrical line is connected by a lead 15 with the fixed conductor 94, and the contacting mov able element 9!. The latter is connected by a lead N36 with the contact of switch assembly K which' is mounted upon rocker 8 i. The other contact of this switch is connected by a lead 58 with the contact of switch assembly I which is mounted upon the swinging insulating element 6!. .The other contact of this assembly is con- .nected by a-lead I09 to a lead lit! that is joined to the'movable contact element 92 and thus ele" trically connected through fixed contact 95 and lead HI to the opposite side of counter we. The contact of switch assembly J which is fixed to block 22 is connected through a lead ll i with the electromagnet 65 which in turn is connected to the lead Hi In the operation of a device of this character, the switch K must be closed-before current can flow eithertoi the: counter hill or to the magnet 55. The counter will receive current if both the switches K and I are closed, while the magnet receives current when the switches K, J and I are closed. The inoperative condition of the device is illustrated in Fig. l, the spring roller ll being efiective through the cable it in drawing 65 the assembly i into a position wherein the lower end of rocker Bl engages. the tip ti; of screw 85, thus holding the conditioning switch K in its open position. When there are no papers passing along the conveyor I and the parts are in the position illustrated in Fig. l, the spring roller ll causes the rollers 24 and iii to press against the roller 3 of the conveyor. The major portion of roller 46 inwardly so that a slight thrust is imparted to push rod 4!, thus holding arms 54 and 56 in such a position the tab II is out of engagement with switch lever I5. Accordingly in this position of the parts the spring I1 is effective in holding switch J in its closed position and the arm 56 is effective in holding the switch I in its closed position against the action of springs 51, 58 and 56.

When the upper edge of a paper is received under the rolls 4% and 24 and particularly under the latter, the tube 2I is eiTective in pushing the entire assembly II away from the conveyor so that the switch K closes. Thereupon current may flow from the lead I05 through the relatively movable contacts 94 and 9|, lead I06, switch K, lead IE8, switch I, leads I09 and II 0, relatively movable contacts 92 and 95, and counter I98 to the lead IOI upon the opposite side of the line. Simultaneously current may pass from switch I, lead I89 and the extension of lead IIfi through magnet 85, energizing the latter, thence through lead II4, switch J, lead I (I4, relatively movable contacts 93 and 96, and lead I02 to lead IIlI at the other side of the line. Thus the counter controlling switch I is closed and is being held in. closed position due to energization of magnet 65.

As the fold in the paper passes out of engagement with the lower roll 45, Fig. 6, relative movement occurring between rolls 24 and 46, the rod fill moves toward conveyor I, permitting arms 54 and 56 to swing in this directioin under the action of springs 51 and 58, so that the tab Ii engages the upper end of switch arm to open switch J. Thereupon the circuit of magnet 65 is opened so that the spring 65 is effective in moving the bar SI and opening the switch I. Thus a break in the current passing to the counter I0!) is afforded, due to the relatively greater pressure afforded by the fold of the paper engaging roll 24 after it has passed out of engagement with roll 46.

The arrangement of the magnet 65 and switches J and I with their associated parts affords a more accurate control of the counter. When arm 56 moves away from arm 6| a slight interval of time elapses before switch J is opened. Thereafter there may be a slight additional interval due to magnetic lag before member 6! swings into engagement with arm 56 and switch I is opened. Due to the slight intervals which may thus elapse, minute irregularities, such as wrinkles in papers, are not sufiicient to cause counter actuation; furthermore, this arrangement avoids a' tendency which the device otherwise might have to afford an inaccurate count due to chattering under certain conditions. In other words, when the magnet 65 is in its portative position, it firmly holds the switch I closed, while if mechanical means alone were depended upon for this purpose, the switch contacts might be held in very light engagement so that any slight vibration would cause chattering and repetitive actuation of the counter.

When the fold of the paper leaves the roll 24 the rolls assume a relative position similar to that occupied when there are no papers passing along the conveyor, although there may be two or more overlapped papers under these rolls so that the switches I and J are again closed, although in this position of the parts the assembly I I may be moved further away from the conveyor I than would be the case were no papers passing along that conveyor, and switch K remains closed.

It is therefore evident that ordinarily the rolls or elements 46 and 24 occupy the relative position shown in Figs. 1 and 3, the entire movable assembly moving away from or toward the conveyor roll 3, depending upon the thickness of the layer of papers and the thickness of the individual papers on the conveyor I, but that as a fold of a paper leaves the element 46, the latter moves slightly toward the roll 3, as shown in Fig. 6, thus permitting the movement of the rod M and the opening of the control switch J and the counter actuating switch I. Accordingly the counter is actuated in response to each folded edge of a paper passing along the conveyor I.

It is evident that the arrangement of the parts 3| and 34 in association with the spring 38 affords a spring take-up means permitting minor variations in the relative positioning of rollers 24 and 46 without affecting the operation of the switches.
