SELECTOR-DISCHARGE MECHANISM.

Application filed August 7, 1922. Serial No.. 580,003.

My invention relates to attachments for printing machines and it has special reference to attachments for machines employing address printing plates and which may be of any of the usual types, such as wrapper addressing machines, strip addressing machines, mailing machines and the like.

More particularly my invention relates to attachments of the characterVindicated in which the address `printing plates delivered from an addressing or mailing machine are automatically selected and segregated in accordance with the expiring date of the-sub'- scriptions that are represented by the separate address plates ejected from the, addressing machine.

The mechanism orattachment of my present invention is applied Ato addressing or mailing machines which employ metallic address printing platesy or address mats Ot'a particular design. It is highly desirable to segregate these [address printing plates` as they are delivered-from the addressing or mailing 1 machine in accordance with the expiring subscriptions as soon as thellast,

newspaper or periodical which is forwarded thereunder has been printed. .I f

It is an object, therefore, of my present invention to provide a selector attachment to be applied tO addressing, mailing or printing machines. of the character described, which will be simple and economicalto construct and will serve most effectively to automatically selectl the address. printing plates of a. predetermined class as, for example, those address printing plates representing expiring subscriptions and, thereafter, to segregate such selected .I address printing plates from the remaining address printing plateswhich may be utilized again. By means of my present invention,the address printing plates of expiring subscriptions are automatically collected within a suitable receptacle or galley and lare thus permanently separated from/the other address printing` plates which are tobe utilized again in the addressing or mailing machine.

Further objects and advantages of my invention will be apparent after reference is had to the following description and the accompanying drawings7 in which- Figure 1 is a side view in elevation of a form of my present invention showing the same attached to the discharge end of an addressing or mailing machine;

Fig. 2 is an end view of the machine of Fig. 1;

Fig; 3 is a view, partially in elevation and partially in section, taken along the plane 3 of Fig.2; f Figs. Al, 5, and 6 are sectional views, respectively, taken along the lines 4-4, 5-5 and G`6 of Fig. 1;

. Fig. 7 is a sectional view taken along theV line 7-7 of Fig. 6; f

8 is `a sectional detail view taken along the line 8 8 of Fig. 1;

Fig. 9 is a View similar to that ofFig. 1 but showing va different operating position than that illustrated inFig. l; i V i *Fig 10 is a plan view of an address printing plate of the type adapted for use in the machine of my present invention: and i Fig.' 11 isV an end view of the address plate of Fig. 10. i

Before explaining the operation of the mechanism ofmy present invention, I will first explain its mechanical construction which 'will then readily permit of an understanding of the Operation of my invention. Throughout the various lfigures of the drawings, the same reference "charactersareemployed todesignate corresponding elements.

Referring to the drawings,.the end frame of. an addressingr machine or mailing ina- .chine to which the attachment of mypresent invention may be secured is represented by the reference character A. A mainshaft 28 of the addressing machine projects through the frame A .and by means of this shaft 28 power is available for operating my attachment.` Address printing plates or address mats 1.2 and 12EL are shown as beingejected from the discharge end of the addressing ormailing machine. These address mats are advanced to the right inxFigure 1 and into operative position inmy selector attachment with pivoted pawls 8O which engage the address mats at their rear edges to advance them along the center rail 81 and the guide rails 66, as shown in Figure 4. The reciprocatingr member 71 operates through a range equal to the longitudinal dimension of the address mats and, therefore, each time'that the reci Jrocating member 71 moves to the right in Figure 1 or to the left in Figure 3. an address mat, such as 12, is advanced forwardly a distance equal to its length. It is, therefore, obvious that a continuous supply of address mats, as they are ejected from the addressing or mailing machine` are advanced one by one by means of the reciprocating member 71 and the pawls 80 into operative relation With my selector mechanism. As mentioned above, the mechanism for feeding the address mats such as 12 and 12, forms no part of my invention since this mechanism is well known in the art. In connection with my present invention I have shown the feeding mechanism of the character described' in U. S. Patent No. 1,281,014 to Huneke.

My selector mechanism operates upon the address mats as they are delivered from the addressing machine and automatically selects those address mats of expiring subscription and then segregates such selected mats from the other address mats so as to ensure that a subscriber of the periodical or newspaper will not receive the periodical after his subscription has expired.

A cam 53, as shown in Figure 6, is mounted upon the main power shaft 28 and to the left of the main frame A of the addressing machine, as shown in Figure 1. The cam 53 is adapted to actuate a lever 33 that is pivoted at 32a in a bracket 32b which is secured to one of the guide rails 66'of the addressing machine. The other arm 30 of the lever 33 serves as a. supporting'platform for a plurality of selector needles 29 that are retained in openings formedin a selector block 37. The lever arm 30 is also provided with a projection 30a upon which is mounted an actuating member 32 for the electrical contact members 33a.

The main shaft 28, at its outer end, is provided with Va spiral pinion 27 which meshes with a. spiral gear 26 mounted upon a rotatable shaft 24 and is journaled, as shown in Figure 2,y in bearings 25. The bearings 25 are supported upon a mounting plate 39 which is bolted to the main frame A of the addressing machine. VThe shaft 28 is constantly rotating during the operation of the addressing machine and, as a consequence, the shaft 24, in turn, rotates. Upon the shaft 24 there is mounted a cam member-16a and a cam member 45, as shown in Figure 8. The cam member 16a, having a cam guide way 16 formed therein, is keyed to the shaft 24 by means ofV a key 16". The cam member 45 is rotatably mounted upon the shaft 24. As

,shown in Figure 3 the guide Way 16 has a sharply curved portion 16?and two reversibly curved portions 16h. The cam roller 17 is received in the cam guide way 16 and is connected to one end of a lever 18 that rocks a rotatably mounted shaft 19 which, in turn, is journaled inbearings 20, Figure 2, that are mounted upon a laterally projecting bracket arm 20LL which is integrally formed upon the mounting plate 39.

The second cam 45, which is in the nature of a segmental cam, is adapted to engage a roller 46, Figure 9, which is connected to one extremity 47 of a curved lever arm 48 that is pivotally secured at 49 to the lever arm 18. The curved lever arm 48 is connected at its end 50 by means of a link 51 to an address mat packing arm 15.

The address mat packing arm 15, as shown in Figure 3, is secured to the shaft 19 Which is oscillated by means of the lever 18. Since the cam 16a continuously `revolves with the rotation of the shaft 28, the lever arm 18, which is actuated by the cam 16, imparts a continuously oscillating motion to the ad- Y dress mat packingvarm 15. Under normal conditions, therefore, the address mat packing arm 15 oscillates uniformly through a relatively small arc but the movement of the packing arm 15 may be modified by means of the lever 48 which is actuated through the agenc of the cam 45. Movement is im,- partec to the cam 45, as will be hereinafter explained, when a spring-pressed pin 43 of Figure 8 projects into a recess 44 formed .in the cam member 16a. The spring-pressed pin 43 Ais housed in the cam member 45 and is actuated by means of a compression spring 42 when a clutch block 40 secured on the end 41 of a'lever 36, Figures 1 and 2, is withdrawn from the annular groove 55, formed in the cam member 45. VWhen the clutch block 40 is Withdrawn from the annular recess 55, the spring-pressed pin 43 projects into the recess 44 and thereby interlocks the cam 45 with the cam 16a. These two cam members, therefore, will now rotate in unison with the shaft 24. The cam 45 is also provided with a braking surface 59 whereupon a friction brake-shoe 58 continuously rests, as shown in Figure 1. Therefore, when the cam member 45 becomes disengaged from the cam member 16a, the brake shoe 58, being pressed against the braking surface 59 of the cam member 45, will hold the latter stationary and against rotation.

Those address printing mats employed in the addressing machine, and which are subsequently submitted to the selector mecham nism of my present invention in order to segregate those mats ofl expiring subscriptions, are illustrated in Figures l10 andfll. These address mats are formed of metallic plates, preferably zinc, and are of rectangular form having parallel longitudinal integral ribs 100 and 101 formed on one face of said plate and spaced from its edges. Integral type 102, constituting the name and address or other information of the subscriber, is struck up on the same face of the plate between the longitudinal ribs 100 and 101 and is slightly higher than the ribs. The edges of the plate are bent over as illustrated and serve as means for guiding the address mats under guide ways 66a that are attached to the Guide rails 66 over the selector block 37, as shown in Figure 6.

Notches 103 and 104 are cut inthe ends of the address plate adjacent `to the lower longitudinal edge. These guide ways 103 and 104 serve'to hold the address mats in the receptacles or receiving galleys, as willv ing of thesebosses 105, 106 and 107 areV dependent upon the date upon which the subscription of thishparticular subscriber expires. Now, fassume that on a particular date all address rnats of the subscribers whose subscriptions expire on this date are to be automatically segregated from the total quantity of mats ejected from the addressing machine. Therefore the selector needles 29 will be positioned in such holes formed in the selector block 37 that all mats having the properly*positioned bosses 105, 106 and 107 correspondingly located are to beseparated from the quantity of matsldelivered from the addressing machine. As explained in connection with Figure 6, the three selector' needles 29 are supported upon the arm 30, which forms a part ofthe lever 33. When the three pins 29 are received in the select-ive bosses formed in the address mats, 4the contact actuator,

32, likewise mounted upon theV leve`r-`33, is permitted to engage the two opposed and spaced contact members 33, as shown in Figures 6 and 7 since the leverarm 30 may then move through its full range of travel. When the contactl ine1nbers33a are in engagement an electrical circuit is connected through the leads 108 and109 which serves to energize the electromagnet 34 of Figures 1, 2, 3 and 9.

In Figure 1, the electromagnet 34 is shown as being deenergized and, as a consequence, the armature 35 and lever 36 occupy the positions wherein the clutch `wlien the Contact members 33a are in engagement, the electromagnet 34 attracts the armature 35 and,`therefore, causes the lever 36 to take the position shown in Figure 9. As a. result, the clutch block 40 is withdrawn from the annular recess of cam 45, and, as hereinbefore explained, the cams 16a and 45 are then operatively connected to each otherythrough the spring-pressed pin 43.

Then thecani'45 rotates in` unison with the cam 16a upon the shaft 24, the cam roller 46actuates the lever' 48 and the link 51, thereby lowering the tamping foot 15", Figure 3, of 4the tamping arm 15. In this circumstance, the tamping foot 15c occupies its lowermost position, as shown in Figure 9 and, therefore, the address mats 12 and 12, as they are fed adjacent to the tamping foot 15C, are receiveduponV its top surface. Theaddress mats 12'* and 12 are moved in succession J above the selector mechanism, the address mat 12a being forced from its position above the selector mechanism by the next succeeding address mat 12 which takes the position above the selector mechanism as theaddressinat 12i is forced into alinementwith' the receptacles 13 and 14. `Since the tamping arm 15 is continuously oscillated the addressmatsreceived on its top surface will on subsequent upward movement ofthe tamping foot 15c be forced upwardly into the upper receptacle y14 and thus segregated from `the quantity of address mats ejected from the addressing machine. d i

It is to be understood, of course, `that the electromagnet 34 is energized only when address mats having a predetermined arrangement of selective bosses thereupon pass over the selector block 37 lof Figure 3. 4

Again, the cam member 45 only rotates upon the shaft 24 when the electromagnets 34 are energized. In turn, the lever 48 is actuated only when the cam 45 is rotated and, therefore, the tamping foot 15c occupies its lowermost position only when those address mats of expiring subscriptions are to be received on its upper face so that they may subsequently be injected into the upper receptacle 14. g f

Ihe selector block 37 is provided with a plurality of spaced openings in which the .i selector pins 29 may be positionedand the address mats are provided wit-ha series of markings or symbols, as shown in Figure 10, which, when the address matsl are directly above the selector block 37, register Ywith the openings in the block. The bosses 105, 106 and 107 are struckup on the address mats in accordance with a code which, on a certain calendar date representing the date of the expiring subscription, may be i lo designated on the address mat by the proper 'location of the selective bosses over these symbols. It is to be understood that the position of the selector needles 29, in the various openings, may be varied at will and arranged to accord with the particular code designation representing the predetermined ex iring date of subscription.

n the event that address mats pass over the selector block 37 which are provided with selective bosses t-hat do not admit of the closing of the electrical circuit throught the electromagnet 34 and through mechanism of Figures 6 and 7, the ,cam` 45 will then be held against rotation by means ot the friction brake 58 which engages the brake surface 59 on the cam member 45. The cam 16a will then be the only one rotating with the shaft 24 and, consequently, the packing arm 15 will partake of its normal oscillatory motion which constitutes an oscillation through a relatively small arc. Such address plates as do not permit of the closing of the electric circuit through the electromagnets 34 are fed over the mat center rail 81, as shown in Figure 4, and under the tamping foot 15c of the mat pack ing arm 15. These address mats, as they are fed under the tamping foot 15C, engage a stopV 15a which precludes them rom being advanced beyond the point of registration with the opening of the lower receptacle 13. lVhcn the tamping t'oot 15c moves downwardly, it will engage the upper face of the mat immediately thereunder and orcegsaid matinto the lower receptacle 13, which is provided with two spaced guide ways 22, as shown in Figure 2, which engage the notches 103 and 104 formedupon the mat. The mats received in receptacle 13 are precluded from being ejected therefrom adjacent to the tamping foot 15C by reason ot' the springs 21 and, in this manner, the mats accumulated in the receptacle 13 are prevented from eirpandinV backwardly. The address mats receive in the receptacle 13 are fed by the curved guide ways 22 into the usual galleys or trays, not shown.

As hereinbefore explained, those mats which it is desired to segregate from the quantity of mats ejected from the addressing machine, when positioned above the selector block 37will receive the selecting pins 29 in the correspondingly positioned bosses 105, 106 and 107 which thereupon will permit of engagement between the electrical contact members 33 of Figures 6 and 7. The electromagnet 34, on being energized, will effect operative engagement between the cam members 45 and 16 and, consequently, the tamping arm 15 will be drawn downwardly through the lever 48 and 'the link mechanism 51, to the position shown in Figure 9. As such an address mat is fed forwardly, it will be received on the top surface of the tampiug foot 15c and abut against a stop 15d. When the tamping foot 15" moves upwardly, the tamping arm 15 is released from the lever 48, as hereinafter to be explained, and, conse uently, the mat received on the upper suriace ot' the tamping foot 15n will be pushed into the upper receiver 14.

As shown in Figure 4, the lower portion of the receiver 14 is provided with two hinged, opposed and spaced dogs 52 that have inclined faces 52a. The mats received on the upper face of the tamping foot 15c are, therefore, forced upwardly between the two dogs 52 and precluded Vfrom moving backwardly by reason of springs 110 that are constantly pressing against the hinged dogs 52. The mats which it is desired to segregate are, therefore, su ported upon the teeth of the dogs 52 an asv they .accumulate, are threaded upon the galley 22 of Figure 5. As shown in Figures 1 and 9, the galley 22 of the upper receptacle 14 is ref movably held therein by means of springs 68 which are secured to angle irons 67 that serve as a supporting structure of the upper receptacle 14. The upper receptacle 14 iS supported upon a bracket 13 by means of screw bolts Y69.

The lever 33 of Figure 6 is actuated by means of the cam 53 during each revolution of the main driving shaft 28. As a result, the contact actuating member 32, during each revolution of the shaft 28, moves down Wardly in order to break the electric circuit between the opposed electrical contact members 33. The relative position of the cam 53 is so determined that immediately after an addressing printing mat has been received on the upper surface of the tamping foot 15, the electrical circuit through the electromagnet 34 is disrupted and, consequentl the tamping foot 15c may partake of its fu l upward range of movementV thereby forcing the printing address mat representing the expiring subscription into the upper receptacle 14. By referring to Figure 4, it will be readily apparent how the tamping foot 15c may force address mats into the upper ,receptacle 14.

The cam members 16a and 45 will continue in engagement as long as the spring-pressed pin 43 is received in the recess 44. To withdraw this spring-pressed pin 43, the clutch block 40 is provided with an inclined surface 57 (Figure 2) which is designed to cooperate with an inclined surface 56. formed on an extension 56, Figure 8, that is comprised in the Spring-pressed pin'43. As the cam 45 rotates the-inclined surfare 56 of the pin 43 will effect engagement with the surface 57 formed on the clutch block 40 of the lever 36 and, therefore, as the cam 45 contumes to revolve, will accordingly oppose llO the action of the `spring 42 and forcethe pin 43 out of the recess 44into the position shown in Figures 2 and 8. Of course, thel pin43 will occup'fv the position shown in Figures 2 and 8 as ong as the came 45 is stationary and the clutch block 4() is received in the annular recess 55. Immediatelyupon Withdrawal of the clutch block 40, from the annular' recess 55, which is occasioned when the electromagnet 34 is energized, the springpressed pin 43 will be released Aand, as a consequence, effect engagement between the cam members 16a and 45. It will be ob served, however, that the clutch block is withdrawn from the annular recess 55 only when the electromagnet 34 is energized, thus attractingthe armature 35, secured at the lower end of the lever, 3b,` as shown in Figure 9. i

When the cam members and 16a are operatively connected through the agency of the pin 43, the friction brake 58 is incapable of holding the cam member 45 against rotation but, as soon as the electromagnet 34 is deenergized and `the clutch block 4f)` is received again in the annular recess 55, the two cams will become disengaged and, under this circumstance, the friction brake 28 will then hold the cam 45 against `further rotation. i y s Y The tension spring 54 which is attached to the lever 36 serves to positively hold the clutch` block 4.0` in the annular Vrecess 55.

The tension spring 61 is connected at 62 to the lever 18 and at 63 to the end 50 `of the lever 48. The tension of the spring 61, as

, shown in` Figure 1, serves to hold the lever arm 48 in `such a position that the link 51 is either in alinement with, or just to the rear of, a center line extending `between the pivot 49 of the lever 48 and the pivotal connection 5li between the link `51 and the packing arm The position of the lever 48 maybe adjusted by means of a stop screw dress printingplates or address mats as they are ejected fromthe addressing machine are received byV my selector mechanism and throughdistinctive markingsl formed on the address mats are selectedin such manner that those address mats representing expiring subscriptions areV segregated and collected within the upper receptacle 14 while the other address mats are ccllectedrin the lower receptacle 13. i i
