SELECTIVE ATTACHMENT FOR ADDRESSING MACHINES.

Application filed June 8,

The invention relates'to addressingmachines in general, and more particularly. to that type in which a series of stencil cards form a part of the printing mechanism. It

is here illustrated as it would be applied to an addressing machine of the general construction' shown in Patent No. 1,256,509

granted to E. D. Belknap Feb. 19, 1918, which has a printing mechanism and a card feeding mechanism both under control of the operator for printing from any one stencil card and discharging it, or for discharging it without printing from it, or for holding it in printing position while several printing operations are performed with it.

The object of the present invention is to automatically stop the machine when a card having certain classification features arrives in printing position although the operator continues to hold down. a pedal which nor-- down a pedal which leaves the driving clutch in gear. There are three such pedals in machines of this type. Pressmg down any one of these will start the machine, but, on its release causes the machine to stop at the end of the current cycle. One pedal, when down,

starts the machine printing from all cards fed from the magazine. A second pedal, when pressed down, causes the machine to skip all cards, and a third pedal (in the machine as marketed), while held down, causes the machine to repeat or print a series of impressions with one stencil card.

In our Patent N o. 1.518.912, granted Dec.

9, 1924, we have described a selective attachment for the machine of the .prior Belknap patent, above referred to, by which attachment such machine may be set so as to run continuously (instead of stopping atthe end of each cycle unless positively controlled by the operator to continue) but will be automatically stopped whenever a card of a special class reaches printing POSltlOIY,

thus enabling the operator to then resume 1926. Serial No. 114,415.

control of the machine and either skip or print from that particular card, also thereby at the same time resetting the machine so that it Will again go on printing or skipping all cards until another specimen of the selected class again trips the mechanism and automatically stops the machine for a reexercise. of the operators power of choice as to what is to be done with the card then occupying the printing position.

The object of our present invention, which may be called a specific modification or improvement onthe broadidea disclosed in our above mentioned patent, is to produce this automatic action, which will stop the machine, while the operator is holding down either the printing or skipping pedal to produce the desired usual operation ofthe machine,as contra-distinguished from our prior specific embodiment 20f an automatic trip attachment by which the pedal is locked down to keep the machine running, and that look is tripped by the selective mechanism to permit the pedal to rise and thereby stop the machine, all in the manner described in the Be knap patent; both forms of our broad invention being primarily designed as attachments to the original machine of the Belknap patent, but being capable of application to other machines of the same general type. a

To accomplish this above described result we employ detachable connections from the printing pedal and from the skipping pedal -to the clutch throw-out mechanism, and enable the selective mechanism (when actuated by a card of the selected class) to break whichever such connection is under its con trol at the time. Consequently the clutch then throws out and the machine stops at the end of the current cycle, although the operator is still holding down one of the pedals that normally cause it to run 'on, and the operatorimust thereafter re-establish the thus brokenconnectionto the clutch throw-out before he can again start the machine by again pressing down that particular pedahwhich is under selective control. Ourpresentinvention also embodies certain other specific features of operation and advantage which will be hereinafter pointed out in detail.

Throughout the drawings like reference characters indicate like parts. The general structure and mode of operation of the addressing machine which is of standard form made under the above mentioned Belknap patent will first be described in part and then the structure of the attachment thereto, constituting the present invention, will be explained, together with the manner in which it automatically controls the operation of the said machine.

A is a magazine of address bearing stencil cards which are fed to an inking and impression mechanism, generally represented by B. along rooved card'guides 36, extend bottom of magazine A, through mechanism B, to a receiving magazine C.

The general structure of the machine comprises the uprights 1, 1, cross bars 3,23 and table Motive power is transmitted from electr1c-motor4. through belt 5 to grooved pulley 6, journaled on stud shaft 7. This pulley is thereby rotated in a counter-clockwise direction (looking at Fig. 1 and, through a clutch 10 (shown in detail'in Fig. 1 rotates main crank (Figs. 1 and 1). This crank, through connecting rod 30, bell crank 31, (pivoted at 32) and link 73, reciprocates card feeding claws 74, which, on their forward travel to the right hand (Figs. 1 and 10), feed out the bottom card 43 from magazine A along guides 36, toward inking and impression mechanism B. Said crank 7 0. through connecting rod 71, also reciprocates T-cam 46, which operates said inking and impression mechanism. This cam 46, pivoted on shaft 45 which is held in housing 48, has a cam slot 66 which engages roller 65 mounted on arm 64, of a lever 6264, pivoted at 63 in housing 67, the other arm 62 of which lever. is pivoted to yoke 60, which operates .an inking roller (not shown) along the under side of card 43" (Fig. 2) which is in printing position. No printing operation results, however, unless an article (such as an envelope, Wrapper or catalogue) has been first placed by the operator over said card 43 and the platen head 55 has been swung down upon it.

T-cam 46 also operates said platen head 55, unless the operating mechanism therefor has been disabled, as will be now described. Platen 55, pivoted on the main frame at 54, is normally held up in the position shown in Fig 1 by. spring 56. On the depending arm 53 of said platen, however, lever 51 carrying roller 50 is pivoted at 52 and is normally held down in operative position by spring 57, so that said roller 50 then engages the external face 49, 47 on said T-cam 46. Consequently, on eachdownward movement of 46 platen head 55 is first swung down by cam face 49 upon the article to be printed (while the concentric portion of cam slot 66 is traveling over roller 65) and then held in this operative position by cam face 47 while the upper, non-concentric portion of cam slot 66 drives-the ink roller up and along under the card 43", so that ink is forced through the stenciled portionof the u n a impression operations, whlch permits the above stated sequence of operations. results from the d-iifering angularities of the connectmg rods 71 and 30 with reference to their common crank 70, and from the fact that the amplitude of motion of the card" feed claws 74 is greater than that dimension is coming back to its 'positionof rest while the card teed claws are going forward to feed out a card, butthe card feed lags behind the T-cam 46 by an amount TOPICS-011ted by the crank angle and. in addition to this, when the claws 71 do begin to feed out card 43 from the bottom of magazine A, said card moves some distance before striking the next card. 43 ahead of it, and, through said card 13 beginning to eject card 43" from printing position. By that time roller 50 has run ott section 47 ot the cam face on -16 and is on section 19,50 that platen head has begun to liftand card 43 is free to move.

Normally the operation of the machine is not continuous. The clutch 10 is norn'ially thrown out of engagement at the end of each complete revolution by a cam-shaped throwout member 72 pivoted at the back of the main frame, as shown in Fig. 1, and engaging spring-pressed pin 10 to withdraw it romengagement with dog 10" on the hub of pulley 6, and, when so thrown out, leaves the parts in the position of rest shown in If igs. 1 and 1 with cam member 46 and platen a5 raised, and with a card 13 in printing position ready for the next cycle. Each card -13 has an extension 58 on the forward part of its frame, as shown in Fig. 11, on which is maintained a record of the customer whose address is given by the stencilized portion of the card. and as this extension projects from under the platen head 55 the operator can.

read said record, and if he then wishes to send the catalogue, or other article he is handling, to said customer he presses down on pedal. 17 (Figs. 1, 1 and 8) which is pivoted at 18 and connected by link 97 (F ig. 1.) and a special mechanism to throw-out'member 72. This permits the clutch 10 to reengage and the machine then performs a printing operation and continues to feed, and print from, the cards as long as pedal 17 is held down. 43 is a panel of specially prepared paper in each card which can be stencilized in a typew'riting machine.

Spring 19 returns clutch throw-out member 72 to normal position as shown in Figs. 1 and 1. and causes the machine to stop at the end of the current cycle whenever it is per mitted to act by the operator removing pressure from both pedals 17 and 104.

The skip mechanism by which the operator can disable the printing mechanism by disconnecting platen 55 from the driving mechanism. while permitting the card feeding action to proceed, is operated'by pedal 104 which is also connected to the clutch throw-out member 72 by link 97, and-so is able to pull down member 7 2 overcoming the resistance of spring 19. Downward motion of pedal 101, which is pivotcd at 105 (Fi 8) to the oscillating pedal yoke 89 in line with the pivot bearings 18 and 18 for the latter, oscillates skip lever 108, which is pivoted on shaft 32. such motion being transmitted by link 107, pivoted to pedal 10% at 25. The free end of lever108 is located under the pivot pin'of cam roller 50, and, when raised by depressing pedal 10 1, moves staid cam roller upward on its'swinging support 51 away from, and out of engagement with. T-am 16, so that vibration of said cam is not transmitted to platen head and the latter, remains at rest in its uppermost position. Com-:equently, the inking rollers reciprocate idly under the stencil cards as they come into printing position and no ink is forced through them and no printing is done even if an envelope or sheet of paper is held by the operator in printing position, because platen does not move down to press such envelope against thestencil card beneath it. 106 is an adjustable stop carried on skip lever 10S and engaging link 107 to limit the upward movement of 107, and cons'cquently also the upward movement of skip pedal 104 under the pull of its supporting spring 110.

It is evident that so long as both pedals 17 and 104 are connected to link 97. a brief downward pressure on pedal 17 will cause the machine to print from the card in printing position and. as spring 110 suspended from fixed pin 111 pulls pedal 17 up as soon as the operators foot is removed, then stop at the end of that cycle. Also that if a brief downward pressure is given to the skip pedal 104, the machine will skip the card in printing position and stop at the end of that cycle as spring 110 anchored on fixed pin 111 pulls up that pedal; and that if either pedal 17 or 104 is held down continuously, the machine will accordingly print or skip con tinnously.

The object of the present invention is to introduce means wherebv a selector apparatus may stop the machine when a card of a predeterminedclass reaches printing position. notwithstanding the fact that the operator is holding down either the print ing pedal or the skip pedal. This consists of suitable apparatus (best shown in Figs. 6 and 7) for automatically breaking the connection between either pedal 17 or 104 and link 97 and comprises the lock lev r 98 pivoted on theframe cross bar 23. and to which lever the lower end of link 97 is pivoted together with a pair of dogs 99. 99. pivcterl at 100 to lever 98 and engaging notches 102, 102" in links 101. and 101 respectively pivoted to pedals 17 and 104.. So long as these dogs are in engagement with their respective notched links, downward movement of either pedal will be transmitted to link 97 and start the machine because each dog rests on a rigid stop 119 or 119 cast on lever 98. Links 101. 101 are normally held in engagement with dogs 99 and 99 by tension springs 103, 103, but, if either of said links is swung away from its cooperating dog, the compression spring 109 or 109 under said dog and pocketed in stop 119 or 119 will swing it up into the position shown in Fig. 7. tree from engagement with said notch. The means for thus freeing either link 101, 101 from its coo 'ierating dog comprise the trip bar 30 pivoted to the core 27 of solenoid Z8, and having a notch 20 (Fi 1) adapted to engage either pin 118. set in the upper vportion of link 101. or pin 118, set in the upper portion of link 101. Trip bar 26 is suiiiciently flexible laterally to be moved by the operator grasping the loop 117 at its outer endto cause it to engage either of these said pins. \Vhen placed on either pin it is held down in such engagement by spring 11. If its notch 26 is hooked over pin 118, it is evident that whenever the ope 'ator is running the machine with printing pedal 17 depressed and solenoid 28 is energized. link 101 will thereupon be pulled out of engagement with dog 99 and lock lever 98 will be permitted to rise, thus throwing clutch throw-out member 72 into operative position and stopping the machine at the end of the current cycle. Also if trip bar 26 engages pin 118 and the operator is running the machine and skipping cards by holding down pedal 104, any energizing of solenoid 28 will similarly pull link 101 out of engagement with dog 99 and thereby permit lever 98 to rise and sin'iilarly stop the machine.

The purpose of thus stopping the machine, with one of the selected cards in printing position, is to give the operator time in which to read the record on the extension margin 58 of said card and determine whether he will print from it or skip it. Thus if the selected class of cards with which the selector device has been set to operate contain the addresses of hardware merchants, the order to the operator may be that mail matter shall be sent only to such hardware merchants as may have purchased $50.00 worth of goods during a given prior period, and consequently the operator will have to read the record on the card to determine whether he shall print from it or skip it. If he has been running the machine with the skip pedal 10 1 down and the trip bar 26 connected with pin 118. link 101 will have been pulled out of cngagement with dog 99 and the machine thereby stopped. It the operator finds on reading the record on the card in printing position that he should address an envelope or wrapper to this particular hardware merchant,

he will momentarily press down printing pedal 17, thus pulling down the clutch throw-out member 72 and causing the machine to make one revolution and print from that card, the transferring of his foot "from pedal 104 to pedal 17 having released the. former and thereby reestablished the con nection with the platen by allowing cam roller 50 to drop into operative position. A fter printing from this card, the operator will transfer his foot to pedal 1.0 1 and the machine will continue skipping cards as before until another one comes along having the particular notch or arrangement of notches which corresponds to the predetermined classification.

11 however, a reading of the record on the card shows that the customers purchases have not reached $50.00 and the operator accordingly ,sllOllltl skip it, he must reestablish the skipping connection and, to do this, he presses upon resetting button 115 on the end of connecting rod 114, (Figs. 1 and 1") the lower end of which is journalled in the free end of link 113 pivoted on pin 100 on which both dogs 99 and 99" are mounted, and, this rod 114 having its lower end 112 extending over both dogs, as best shown in Fig. (3, this downward pressure of button 115 will force down whichever dog has been tripped and cause it to reengage its cooperating link. In the case assumed, the dog so first tripped and afterwards reset, will be 99. On re moval of pressure from button 115, spring 116 will lift the resetting rod and reestablish normal conditions. Thereupon the operator can again press down pedal 10% (or continue to hold it down. if he has not taken his foot oil of it) and the machine will again start into operation. skipping cards as before, until another card with the proper notch or arrangement of notches again trips the clutch.

If, on the other hand, the operator is run ning the machine with the printing pedal down and the trip bar 26 in engagement with pin 118, the arrival of a card of the predetermined class, or classes, will pull link 101 out of engagement with dog 99 and the operator Will then either step on skip pedal 10% to skip that card, or. if he wishes to overrule the automatic selection of the machine, reset the connection to pedal 17 by means. of pressure on the button 115 and thus cause the machine to resume operation as before. In either case, the automatic trip disables the pedal which is then in use so that the operator can accomplish nothing by moving it up or down until he has first reestablished its connection to the clutch throw-out either by depression of the other pedal. or by pressure upon the resetting button 11:"). The reason why either dog, as 99. will not reengage its cooperating notch in link 101 until the lock lever 98 has been first pulled down by [he Fig. 11.

other pedal, or the dog forced down by the reset pin 112, is because such dog is thrown 11 upward by its spring 109 as soon as released from its cooperating notch as indicated in Fig. 7

The selector apparatus comprises a series of feeling fingers 34 cooperating with stencil cards having a corresponding series of notches such are shown at 44, 44, 44 in When any one or more of the fingers 34 fall into one or more of the notches of the cards as the latter are fed along the card guides 36 and reach the position shown at 43 in Fig. 2, the dropping of any one finger into such ano-tch closes the electric circuit which energizes solenoid 28 to trip the main clutch 10 and cause the machine to come to a stop at the end of the current cycle.

The particular arrangement of apparatus for closing the electric circuit 29-through battery 33 and solenoid 28 is best shown in Figs.- 3, 4 and 5. There are as many notches 44, 44, etc., as can be convenientl cut in a card and the same number of ngers 34. Each notch may represent a class of cards, and combinations of two or more may represent additional classes. Each finger 34 is independently pivoted at 35 on an individual housing 157, all of the housings 157 being rigidly supported upon the main selector housing 8which is supported over the card guides between the magazine A and the printing mechanism B. Housing 8 is fastened to the guides byscrews 8 engaging slots 8" therein. This permits the housing to be adjusted in position so that fingers34 will have their lower ends exactly over notches 44, in the card which is in position 43. Each finger is connected to its housing 157 by a tension spring 9, which is fastened to the finger at one end and to pin 57 in the housing at the'other. Said pin 57 also engages the arc-shaped slot 34 in afin'ger and so serves as a stop to limit the finger movement. When the finger is down in one of the operative positions as shown in full lines in Figs. 4 and 5, spring 9 tends to pull it into the lowermost of said positions as shown in full lines in Fig. 5. When any particularfinger is not in use it is swung up into the vertical position shown in dotted lines in Fig. 5 and also in full lines in Fig. 4, and is also held in this vertical position by the same spring 9, as indicated in dotted lines in Fig. 5. Each finger 34 has a rear wardly extending lug 11 which cooperates with a dog 12 on shaft 39, on the outer end of which is mounted the hammer 40 for forcing spring contact strip 38 intermittently against stationary contact screw 37, thereby closing the electrical circuit 29, unless the switch68 therein is open (see Fig. 4). 42 is a back stop for hammer 40 preventing it from swinging so far to the left that dogs 12 will turn beyond the zones of motion of lugs When the machine is at rest, all of the fingers 34 in use are supported in the upper operative position, shown in full lines in Fig. 4 and in broken lines in Fig. 5, by means of the oscillating cam bar 13, pivoted at 14 in housing 8 and oscillated by crank 15 connected by link 16 to short crank 65 on the pivot shaft 63 of the ink roller operating lever 6264. When, however, the T-cam 46 has been pulled down far enough to begin operating the inking roller by reason of the fact that cam roller 65-has entered the upper portion of cam slot 66, and the platen 55 has been lowered and the printing operation is in progress, the upward motion of the short crank 65 (coincident with the movement of inking lever 62) oscillates cam bar 13 into the full line position shown in Fig. 5. This permits the finger or fingers in operative position to drop into any notch 44 thereunder, as shown in Fig. 5, and to so close elertrical circuit 29, as'before described,

thus energizing solenoid 28 and causing it to break the connection from the pedal in use to the clutch throw-out member 72, with the result that the latter rises under the pull of spring 19 and, when the current cycle of operations of the machine is completed, trips the clutch and stops the machine. Before this cycle is completed, however, the upward swin of the T-cam 46 has caused the lifting of pl aten 55, thus releasing the card from which the printing has been done, and the second half of the rotation of=the main crank 7 has driven the feed claws 74 forward, feeding the card 43*, with which finger 34 has cooperated, forward into printing position, and this card 43 has kicked card 43 out of the printing zone into the receiving magazine C. If, however, when the finger or fingers in operative position have been allowed to drop by this oscillation of cam bar 13., there is no notch 44 under said finger, it will then rest on the card frame before it has moved far enough to cause its lug 11 to oscillate hammer 40 and close circuit 29, and the solenoid will not be energized and thedclutch throw-out mechanism not operate i To insure conjoint action of a series of the fingers 34 so that none of them will drop unless all of them register with card notches, the fingers in operation may be tied together by the pin 34 extending through them and through the swinging yoke 69 position it may be pinned to the yoke by 34.

To furtherv extend the number of possible combinations of notches ofany one card, we employ one or more spring metal'clips 59, as

shown in Figs. 11 and 12, which are adapted to snap over the edge of the extension 58 of the card frame and brings their inwardly turned free ends in the holes 59 opposite the notches 44, 44, 44 etc. Each such clip 59 is wide enough to cover any particular notch over which it may be placed and thus in effect blank it out. Thus if it becomes necessary to disable a certain finger 34 which comes opposite a notch 44, in cards which are not to actuate the selector, althou h they have notches 44 which would normally permit such finger to drop, this can be done by covering said notches in each such card by one of the clips 59, as shown in Fig. 11. These clips are made of such thin metal that they do not appreciably separate adjacent cards and still they are firmly fastened to any particular card by their bent inner spring ends hookin into anchoring holes 59.

The apparatus which permits the machine to repeat, i. e. print successively a series of copies from one stencil card held in the printing zone, consists essentially of a pedalcontrolled mechanism for totally disabling the card feed claws 74 during any desired number of cycles and positively breaking the electric circuit 29 during such period so that the clutch throw-out cannot be operated while the repeat pedal is held down. This apparatus is best shown in Figs. 8, 9 and 10. The repeat pedal 7 6 is pivoted at 88 in the yoke 89 which is integral with printing pedal 17. As shown in Fig. 1", the pedal 7 6 has a downwardly and backwardly extending elbow which carries an adjustable contact bolt 91 so that, when pedal 76 is pressed downward,- the pedal yoke 89 and printing pedal 17 will also be vibrated to withdraw the clutch throw-out cam 72, if said printing pedal is in gear, and thereby cause the printing mechanism to operate through consecutive cycles as long as pedal 76 is held down. When, however, printing pedal 17 is pressed 'down for any other kind of printing operation the repeat pedal 76 will merely oscillate idly on its movin pivot 88 and on its supporting link 87, without interfering with the normal operation of the machine as hereinbefore described.

The particular preferred claw disabling apparatus herein illustrated comprises a pi.voted mounting for claws 74 at 78 on the sliding carriage 75 and means under control of pedal76 for elevating the rear ends of the claws, and consequently depressing the claws proper, so that they will not engage the bottom card 43 in magazine A, but will reciprocate i'dly back and forth thereunder, thus leavin the card 43 in the printing zone undisturbed. As shown, the rear ends of the claws 74 are connected by a back bar 81 which carries an anti-friction roller 82 on a de ending lug." Normally, the back bar 81 is eld down upon the ad ustabIe stop 79 by menses 84, is lifted under roller 82, and forces it up,

the front end of claw 74 is tipped down so I that it will not engage a card. During any period in which pedal 76 is depressed, roller 82 runs back and forth on track 83. Yoke 84 is pivoted. on shaft 85, mounted on housing 86; and interlocks with the yoke 84 at joint 84 (see Fig. 2), the outer end of'yoke 84 being pivoted to link 87 which extends down to repeat pedal 76. An adjustable stop for limiting the upward movement of link 87 is shown at 92. This stop is so adjusted that it will permit downward movement of yoke 84 sufficient to free track 83 from roller 82 and leave the claw 74 free to operate in the normal way. Carriage 75 slides on guide rods 77, 77.

To break the circuit 29, when repeat pedal 76 is depressed, we employ a circuit breaker comprising the contact pins 20 and 21 mounted in a block of insulating material fastened by screw 96 to the housing 95 depending from the main frame. Pin 21 is normally forced down by. spiral spring 21,

its downward motion being limited by adusting nuts 24. Spiral spring 20 tends to 5 force pin 20 also downward so as to leave a gap between the two pins which will break circuit 29; but, when disabling track 83 is lowered and claw 74 therefore allowed to operate normally and feed out cards, the projecting arm 22 carried by yoke 84 is raised under pin 20 and forces it up into contact with pin 21, thus closing the circuit 29. Springs 93 and 94 normally hold arm 22 in this raised position, shown in broken lines in Fig. 9 and thus close the circuit, also holding down the disabling track 83 out of operative lot) position, but when pedal 7 6 is pressed down the pressure of arm 22 1S removed from pin 20 and the latter is then forced down by spring 2O away from contact with pin 21.

To prevent the disabling track 83 from fallin back into normal position at some perio in a cycle of operations when the machine is set for repeating, which would permit the claw 74 to rise and feed cards forward, thus discharging the card in printing position from the machine before the desired number of impressions may have been taken therewith, as might happen if the operator inadvertently took his foot off of the repeat pedal 76 some time during the first half of a cycle, we employ the device best shown in Fig. 10 in which 120 is a holding dog pivoted to the main frame at 121 and pressed by spring'122 under lever 84 whenever track 83 is raised to disable the feed claw. This dog 120 normally rests against the side of lever 84, as shown in Fig. 10, when track 83 is down in normal position, as there shown, and the card feed is operating in the usual way. Under these conditions, the arm or finger 125 rigid on pivot shaft 32 and vibrating back and forth with bell crank 31 just touches finger 123 pivoted at 124 to a projection from dog 120. \Vhen, however, track 83 has been raised bypressing down repeat lever 76, dog 120 is pushed under lever 84 by spring 122 and holds track 83 raised until the end of the current cycle at which time the card feed claws 74 are in their extreme. right hand position. The last portion of this feeding movement of the claws, however, has swung arm 125 in a clockwise direction far enough to strike finger 123, which has been swung slightly to the left by the dropping of dog 120 by which it is carried, and then, and then only, is dog 120 swung back by this action to the position shown in Fig. 10, permitting track 83 to drop, and allowing claws 74 to rise into operative position. As a result, these claws are so put back into operative position only at the end of a complete cycle when if the operator has inadvertently taken his foot off pedal 76, the machine will stop and he can resume repeating, if he wishes to do so, from the same card, by again stepping on pedal 76, or if he has printed the necessary number of copies from that card, he can resume printing or skipping operations by pressing pedal 17 or 104 as before described. If this device is not used, the removal of pressure from pedal 76 at any time during the first half of a cycle would have permitted,track 83 to fall and claw 74 to rise in time to resume feeding and discharge the card then 111 printing position, thus rendering it impossible for the operator to get said card back into printing position and resume printing pedal 76 was therefrom, if his release of inadvertent, or premature.

'To provide for the co'ntingency of arm 125 traveling so far to the right (looking at Fig. 10) that it would pass under and be yond finger 123. the latter is pivoted to dog by a knuckle joint which permits it to swing to the left, in a clockwise direction whenarm swings back again, but to drop back into operative position before arm 125 swings forward again in the next cycle. That is to say, when arm 125 engages finger 123 on the forward stroke of the feed claw that finger and the dog 120 swing as a.

'unit on pivot 121, but on the return movement of arm 125, finger 123 swings alone on its pivot 124. The fact that dog 120 is thus swung up into the position shown in Fig. 10 at the end of each cycle of the ing while pedal 76 is being held down because lever 84 is held up by said pedal 76 during such repeat operations. It is only when the operator has taken his foot ofi' machine does not interfere with repeat print- I pedal 76 that this movement of dog 120 permits track 83 to drop at the end of the current cycle, and thereby permit pedal 7 6 to rise and stop the machine at the end of the cycle while ,atthe same time restoring claws 7t tooperative position.

In operating our-invention, if the stack-of stencil cards in magazine A contains a large number of cards of the class or classes to be .used, so that a good deal of printing has to be done with them, the trip bar 26 will be hooked over pin 118 so as to attach the selective device to the printing pedal 17 and the operator Will start the machine by pressing down said pedal. In such case all lingers EH corresponding to notches in cards of still other classes, which are not to be printed from, will be turned down in operative posi tion', but not tied together with pin 34". All cards then fed out of the magazine which do not have a notch 44 corresponding to one of the classes which are to be skipped, will accordingly be fed through the machine and printed from in the usual way. (Under these conditions it would probably happen that there would be a number of classes of cards which were to be skipped and, if so, a corresponding number of fingers 1' would be put down in operative'position but not tied together by the cross pin 34 cam roller 50 away from cam 40, with the result that the machine willagaiu start into operation, feed that card through without printing therefrom, and stop at the end of that cycle (the operator having given pedal 104: only a momentary depression). The pulling down of lock lever 98 by pedal 10% will have given dog 99 a chance to reengage notch 102 in link 101 which has previously been-returned to normal position by spring 8 103, the pull of solenoid 28 having been exerted only momentarily while a finger 3-1 was down in a notch 44. Ihe contact between contact screw 37 and spring contact 38 having been broken either by the movement of the card or by the tipping up of cam bar 13, or by both actions. some tzme before the cycle was completed, link 101 has been freedfrom any pull of the solenoid and has been pulled against dog 99 by spring 103 before said dog has been lowered by the downward swing of lock lever 98 produced by pedal 104. The result isthat the attachment has been reset with both dogs 99 and 99 in engagement with their cooperating links '100, 101 and consequently with both pedals 17 and 104 connected to the clutch throw-out. Therefore when the operator again presses down on pedal 17 the machine starts in again to print from all cards presented to it until a card of one of the exempt classes again reaches printing position and the above described procedure is then repeated.

' If, however, on examination of any of the cards which thus stop in printing position the operator decides to overrule the decision of the machine, he presses down on resetting button 115. thereby causing dog 9%) to Toengage its link 101 without pedal 104: having to he first pressed down, and thereupon he may stop on pedal 17, and cause the machine to resume operations, beginning by a printing from this particular card which the machine would have rejected but which the operator has decided to use after his attention has been called to it by the automatic stopping of the machine.

If the stack of cards to he used contains only a small percentage belonging to the class or classes from which printing is to he done, more rapid work can he done it' the above described arrangement is reversed and the attachment is set by hooking trip bar 26 over pin 11% and then starting the machine by holding down skip pedal 1M. In such cases the finger or lingers ill corresponding to notches representing the class or classes to be printed will be put down in operative position, but not pinned together. Then, as cards of other classes are fed out, the electric circuit 29 will not he closed and the machine will run on skipping them until one oi the class to'be used appears, whereupon the solenoid 28 will be energized, link 101" pulled out of engagement with dog 99. and lock lever 98 and cam lever 72 be permitted to rise, the latter throwing out clutch 10 at the end of that cycle and leaving this card exposed in printing position 43". It. on inspecting said card the operator finds that the decision of the machine was right, he releases pedal lfii and presses down pedal 17 momentarily, thus starting the machine, causing it to print. from that card and to stop at the end of the cycle. He next presses down skip pedal 101 again, and the previously described operations are resumed. Ii". however, he decides to overrule the decision of the machine. he resets dog 99 by pressing down on button 115 and the machine starts, when pedal 104- is presscddown again, skipping said card and all succeeding cards until another member of the class from which printing isto be done. arrives.

In normal operation the pedal in use should be permitted to rise before the resetting button 115 is pressed down and then only its corresponding dog will have to be manipulated by downward pressure on said button in the resetting o oration, but it may be possible to reset whi e the pedal is still held down, it the button 115 can be pushed down far enough and hard enough to also carry down the other dog, and possibly lock lever 98 with it, in order to get the first trip dog down far enough to cause it to reengage the notch in its cooperating link while the latter is in depressed position resulting from the pedal to which it is pivoted being held down. I In both cases above described, the cards in a plurality of classes may be thus selected by the machine for examination by the operator by putting a corresponding number of fingers 31 down in operative position without tying them together by pin 34. If only one class is to be selected, then only one linger is put down, or a nmnber oi fingers tied togcther corresponding to the combination of notches which represents that one class.

Vhen a card arrives at printing position from which a number of impressions are to be taken, the operator presses down pedal 76 as before explained. This, by operation of elbow 90 and set screw 91, also vibrates pedal yoke 89 and lowers printing pedal 17, unless that pedal is already in depressed position. In either case, the movement of pedal 76 lifts claw-disabling track 83 under roller 82 and thereby lowers claw 7 1 to a point such that the continuous-operation of the machine resulting from the lowering of printing pedal 17 will then not feed out any more cards. Accordingly, any number 0'1? envelopes or wrappers or other articles may be eonsecutivelv inserted beneath the vibrating platen and all printed from the same card then in position 43". At the same time circuit 29 is broken by the separation of contact pins 20 and 21, due to the lowering of pressure arm 22 in the manner previously described, and the trip mechanism will not be operated during this repeat printing because solenoid 28 will not be energized, even it the next card, in position 413, should have a notch co-operating with a linger Zl-t down in ope 'ative position over it and dropped into said notch during each cycle oi operation of the machine. Whenever the foot is taken off pedal 76 it will be raised by springs 93 and ill. circuit 2.) will be closed and claw 7-l allowed to rise into normal card feeding position. 1 Among the advantages of our present invention may be mentioned the following: As compared with the particular embodiment of the general idea. illustrated in our prior Patent No. 1,578,912, the present mechanism is smoother and less noisy in operation. Also it requires the operator to constantly keep his ,foot on one of the pedals. which insures closer attention to his work. The present machine is practically fool-proof in that, when it is'stopped by the selectingdevice, the operator cannot inadvertently restart it to do the wrong thin" by further manipulating the pedal he has theretofore been holding down. That pedal has then become disconnected, and the onlything he can accomplish by pedal manipulation is either to do the particular thing for which the attachment has been automatically set, or to operate the repeat device,'-which latter is rarely required. Consequently he cannot easily make any mistake. The selector can be easily cut out by opening switch 68, and then the machine can be manipulated in the usual way solely-by positive action of the operator, as described in the prior Belknap Patent No. 1.256.509. The selector is positive in operation and usuallv the finger-s34 are not dragged over the stencil cards, being lifted and held up by cam bar 13 all the time the cards are in motion. This saves wear on the cards. A multiplicity of selective actions are possible, employing a multiplicity of fingers, with only one contact device 38, 37 for all the fingers, and that device is so far removed from the cards, and envelopes being printed, that any arcing there creates no objectionable fire risk. The movement of contact hammer 40 is so rapid, on account of its long radius of oscillation, that the circuit closing and breaking actions are always rapid, and arcing thereby prac-' tically eliminated. The whole of the clutch manipulating mechanism is located in the rear of the machine, as best shown in Fig. 1, so that the operator can sit with his feet well under the table and his body close to his work of feeding envelopes or wrappers to the printing mechanism. Finally, the entire attachment canbe easily applied to the standard machines of the prior Belknap atent now in use, the finger housing 8 with fingers and circuit controller being a com plete, detachable unit which can be placed cards and that other changes in the details of the refer ed form of. apparatus here n described and illustrated could be made without departing from the principle of our invention so long as some or all of the essential novel features and functions are retained to produce substantially the same result in substantially the same Way. 1

Another feature of advantage in our invention arises from the fact that none of the selective fingers 34: is at any time allowed to rest on a'card while said card is in motion.

This results from the fact that the rotation ofcam bar 13 back toward dotted line position (Fig. 5) far enough to lift any fingers 34: which may be in operative position out of the card notches and above the plane of the upper card surface before the card in position 43 is fed forward by the card 43 which is being pulled out of the magazine behind it. This retarded feeding forward of card 43 with reference to the movement of the printing mechanism (which operates cam bar 13) is due to the cumulative effect of the relative angularity of the connecting rods 71 and 30., and of. the delay resulting from the fact that the travel of the card feeding claws 74 is greater than that dimension of each card which is parallel to the line of feed, so that card 43 moves some distance before it comes in conta t with card 43*, all as previously explained herein.
