Application filed August 14, 1926. Serial No.'129,135.

This invention relates generally to automatic means for tripping the driving clutch of a power-driven mechanism, and to means under control of the operator for afterwards resetting the same so that the machine may continue in operation until the clutch is again automatically thrown out. More specifically it embodies an improvement on the invention described claimed in our U. S. Patent No.1,518,912, granted December 9., 1924, and in certain respects is a modification of the invention described and claimed in our application Serial No. 114,415, filed June 8,

1926. Our invention is herein illustrated in the .form in which it has been applied to an addressing machine of the type covered by U. S. Patent No. 1,256,509 granted to E. D. Belknap February 19, 1918. 1

Our present improvement embodies one device for overcoming the noise and jar created in the operation of certain previously patented apparatus of this general character by inserting a detachable link in the chain of connections from the pedal system (the printing pedal more particularly) to the clutch throw-out mechanism and having the automatic selecting device (not shown) trip this link when one of the predetermined class of cards is fed out of the magazine to printing position, the pedal or pedals remaining locked or held in depressed position until released by the operator, the connection to the clutch being then reestablished. One form of apparatus embodying our present invention is illustrated in the attached four sheets of drawings, in which,

Fig. ,8 is a similar view showing said lock and pedal in the position assumed when said pedalhas been'depressed to reset the pedal connections. I

Throughout the drawings like reference characters indicate like parts.

1, 1,'are the uprights of the main frame of the machine supporting a table carrying the operating parts such as the card handling, printing and selective mechanism (not shown), said uprights being held together by side bars, shown at 3, and cross bars such as 2 and 23 shown broken away.- 10 (Fig. 1) represents diagrammatically a clutch on the main driving shaft of the machine which is usually of the one revolution type, being antomatically thrown out at the end of each cycle of operation of the machine by the throw-out cam 72 when the latter is swung up on its pivot 7 3 by the spring 19 into the osition shown in Fig. 1. 17 is a pedal rigidy mounted on the yoke 89, pivoted on the rear cross bar 2 at 18, 18. Said pedal 17 is detachably connected by notchedlatch link 12, pin 14, lever 98 and link 97 to the throwout cam 72.

This latch 12 is pivoted at its lower end by screw 13 to pedal 17 and has a notch 11 in its front edge which normally engages pin 14 to form the above described train of connecting mechanism from pedal 17 to cam lever 72. The upper end of latch 12 is connected by link 26 to core 27 0t solenoid 28. VVhenev'er solenoid 28 is energized by the selective mechanism, which may be of the construction shown inour Patent- No. 1,578,912 or of that shown in our pending application rial No. 114,415, filed June 8. 1926, or of-any other type, latch 12 will be pulled to the left (looking at Figs. 1 and 3) and notch 11 will then clear pin 14 as shown in dotted lines in Fig. 1. Thiswill allow spring 19 to liftcam lever 72 and throw out clutch 10 at the end of the current cycle,- even though pedal 17 is still held in depressed position.

' the link 26 one end of which is pivoted at 15 to the upper portion of latch 12, while its'othjer end is pivoted at 3 'to thecrank arm 36 on sleeve 35 which is loosely mounted on cross bar 23 of the main frame, which cross bar is of cylindrical shape, said sleeve 35 having operative connections to reset pedal 29, also pivoted on cross bar 23. The preferred form of operating connections between pedal 29 and sleeve comprises a second sleeve 30 to whichpedal 29 is rigidly connected by crank arm 21 and which sleeve isalso loosely mounted on shaft 23 and provided with a projecting lug 38 cooperating with lug 40 projecting from the adjacent end of sleeve 35. Obviously, when pedal 29 is pressed downward, it lugs 88 and 40 are in contact, transmitted to sleeve 35, and link 26 will be pulled to the right (looking at Fig. 1), thus slightly swinging latch 12 suihciently to bring it back into the full line position shown in Fig.1. This will pull. out solenoid core 27 into the position'shown in Fig. 1, cause the latch to engage pin 1% (assuming that pedal 17 is in raised position), and reset the parts so that when pedal 17 is again dopressed the parts will assume the position clearly shown in Fig. 3, the main clutch will bethen disengaged and the machine again started into operation.

In a machine organized to run cont-inuously until the. selective apparatus or other automatic device trips the latch 12 and stops the machine, it may be desirable to provide means for locking the pedal 17 in. depressed position so that the operator need not hold his foot upon it or otherwise positively maintain it in depressedposition by continuous eitort. Int-he apparatus described this is accomplished by the following train or mechanism. Swinging lock member 20 is carried by sleeve 30 and adapted-to engage a lug & on pedal 10% which is-pivoted at to pedal yoke 89 and overhangs the laterally:projecting stud 100 carried by pedal 17. This pedal 10 1 (called the slrip pedal in machines of this character), when depressed, carries down with it pedal 17 and, thereafter so long as lock 20 is in line with lugl, will be held by 20 in depressed position and also hold down pedal 17, thus permitting the machine to run on. NVhen, however, the operator presses down on reset pedal 29, he will swing lock 20 out of line with lug i, as shown in full lines in Fig. 1 and thereupon spring the rotation of sleeve 30 will be (Figs. jection 111 engagement with pin ll, which notch 1s 81- lnultaneously swung into such engagement with said pin by the same or continued movethrough the train of ment of reset pedal 29, connecting mechanism 26 before explained. the pedal 17 through theaction o'l stud 106.

Spring 110 connected at its upper end to sleeve 30, and at its 10a, tends to rotate terminating in link Upward THOlZlOIl oi the crank arm 39 on lower endto slnp pedal also carries up skip pedal 10d sleeve 30 in a clockwise direction, (looking at Figs. 5' and 6) whenever skip pedal 104 is depressed with the result that as soon as lug l: on said pedalgets below the lower end of swinging lock 20, the latter is snapped over into position shown in Fig. 6, so that after the operator removes his foot from pedal 104: it is still held down by lock 20.

Lock 20 is prevented from swinging too far in this resetting operation, and is held in position to register with lug- 1, by projection 2% on the upper side of lug l.

107 is a link pivoted at 25 to skip pedal 10 i and operating a card skipping mechanism, not shown, but similar to that describedin our before mentioned patent, and in Bellrnap Patent No. 1,256,509.

Obviously the above described mechanism renders it possible for the operator to proceed on either of theplans explained in said Beiknap Patent No. 1,256,509. That is to say it he depresses ski pedal 10s the machine will start and continue to feed and skip cards as long as pedal 10;; isheld down, and latch 12 engages pin 14. If he depresses pedal 17, the machine feeds and prints from all cards so long as latch 12is in engagement. Also, if the slrip pedal 104: isloclred down by swinging arm 20 the opertor may tempo;- rarily leave the machine while it is so controlled, as was the case with the modified attachment described in our Patent No. 1,518,912. In either case, it a selective attachment is in use the latch 12 will. be tripped and the machine stopped whenever a card oi? the predetermined class comes into printing position, and the operator can then decide whether to print from that card or to skip it, and accordingly depresspedal 17 or. 104. It the machine is operating on a set 0" cards the major portion of which are to be skipped, the pe lalj104 will be normally locked down, the printing pedal 17 only occasionally and temporarily depressed to produce one printing cyclefthe reset pedal 29 will thcreaftr-r be tem 'ior: rily depressed to reset latch 12, and operations resumed by again lookin down pedal 10 i, and no fur ther adjustments are required.

lit)

llll) assess? If, however, the machine is to be run with a lot of cards the ma or portion of which are to be usedjln printing and only a few of them skipped, two complications would result with the above described apparatus.

Thedesired result could only be attained by the operator holding down pedal 17 and so running the machine to print until a card to be'skipped came along to actuate the selective device. But, as the pedal 10-1 would then necessarily be in raised position, the pull of magnet 28 could not move the latch 12because the lug a would then be up along side of lock arm 20, and sleeves 30 and 33 couldnot be oscillated to permit latch 12 to be tripped. Also, if latch 12 could be tripped under these conditions (as by the insertion of an elastiosection in link 26, for instance), the machine thereby stopped and then pedal 10% temporarily depressed to skip the cardthen in printing position, (after pedal 17 had been temporarily raised to permit latch 12 to reengage) the before described automatic action of lock 20 would produce a complication in that it would lock t ll the machine in skipping adjustment (the moment pedal 10st was thus depressed) and thus cause it to run on, skipping all cards (which should be printed) until a card which belongedto the class which alone were intended tobe thus skipped arrived in printing position, latch 12 thereby tripped, and the machine stopped. After releasing pedals 17 and 104 by depressing pedal 29, and

' thereby resetting latch 12, depressing pedal 104 to skip thatcard would reset lock 20 and repeatthis series of operations, with the result that all cards (except those run off before the described first actuation of the selective device) would be skipped and none could be used for printing. To avoid both these diiiiculties it is necessary to shiftlock arm 20' temporarily so that it' can vibrate without engaging l'ug i when the machine is to be run on the printingplan with only occasional skipping. The preferred means for thus shifting and disabling lock 20 is best shown in Figs. 4 to 8.

Collar 31, which is locked to cross bar 23 by set screw 32, and so serves to prevent sleeve 30 from sliding alongsaid bar away from sleeve 35, has a sectorshaped projection 33 which engages semi-circular jaw 34 on sleeve 30. and thereby also limits the am: plitude of oscillation ofsleeve 30, and pedal 29. to a degree just sufiiciently to give reset-ting crank 36 the amount of motion needed to cause reengagement of notch latch 12 with pin 14. The locus of oscillation of sleeve 30 needed for this purpose may be shifted by adjusting contact screw 38 in lug If then-screw 38 isbackecl off so thatlug 38 must move all the way (or nearly all the way) up to lug 40 before reset sleeve 35 begins to be rotated by depression of pedal then normally held 29, and some means is provided for preventing pedal 29 (when released) from swinging back into the position shown in Fig. 6, look arm 20 will never engage lug 4 to lock pedal 10% down, but position shown in Fig. 7 .to that shown in Fig. 8. That is to say, the oscillation of pedal 29 needed to oscillate reset sleeve 35 and cause latch 12 to reengage can then be obtained without ever causing lock 20 to {register with lug 4. This shift in the locus of operation of pedal 29, lock 20 and sleeve 30. is accomplished by merely loosening set screw and slightly rotating collar 3lflon cross bar 23 ina counter-clockwise direction when looking at Fig. 3 (in .aclockwise ,direction when looking at Figs. lto 8), and reclamping it in this other position by means of set screw 32. Theaccu rate adjust.- ment of collar 31 in .either position is secured by radial pin 43 in cross bar 23ers: gaging sector slot 1-2 in said eollarl l/Vhen the pedal system is to be setfor automatically skipping cards collar 31 set as shown in Figs. and 6 with the left hand end of :lot against pin 13, and lock 20 functions, contact screw 38 in lug 38 protruding as shown in Figs. 3, 5 and 6. When, however, the pedal system is to be set for automatically printing cards (pedal 17 being v down by the operator and pedal 1 being normally held up by spring 110), collar 31 issetinthe position shown in Figs. 7 and 8 with the right hand end of slot 42 against pin 413. This, by op.- ,eration of interlocking elements 33, 34, lllll? its the locus of oscillation of pedal 29, lock and sleeye to the positions shown in those figures, and lock 20 then merely moves idly back and forth in the latch resetting operation, never engaging lug a. To enable this shifted locus of oscillation of lug 38 to have the same effecton reset sleeve as that before described, the contact screw 38* must be backedoif so that lug 38 may more nearly approach lug before reset crank 36 is moved. This last described adjustment is indicated in Figs. 7 and S.

Preferably trip lever 98 is pivoted on cross bar 23 by sleeve 5 and is forked at the end as shown at is to form a guide slot for latch 12. j in length by its contact button 2O carried on screw 22. Pedal 7.6, pivoted at 88 on pedal yoke 89 and having an elbow 90 pro.- vided. with contact said yoke, operates a repeat printing device such as described in our application Serial No. 114,415. ledal 76 is normally held up by spring 93. Collar 41, fast on cross bar 23 prevents sleeves 5, 35 and 30 from sliding to the left. j

lhe complete procedure in operating our invention when applied to the machine pf h B ki ep pate may be briefly ta ed a will oscillate idly from the Lock arm 20 is made adjustable screw 91 for engaging V sitions shown in Fig.

printing position. Solenoid follows: Assuming that the selective. device (not shown) has been setto be operated by stencil cards which are to be use-din printing, parts are adjusted as shown in Fig. 3 and in full lines in Fig. 6. The operator having pressed down skip pedal 104, which has thereupon been locked down by arm 20, the machine starts off, skipping all cards until one of the class to be printed arrives in 28 is then energized and trips latch 12, releasing stop lever 98 which permits cam 72 to rise and trip clutch 10, and pulling reset crank 36 and lug d0 over into the position shown in dotted lines in Fig. 6. The operator then depresses reset pedal 29, which both swings lock 20 so as to release pedals 10d and 17 sothat they can rise and lift latch 12 so that notch 11 will come opposite pin 1 1, and pulls said latch torward into engagement with said pin, parts assuming the position snown in Fig. 5. It the operator then decides to print with the stencil card lying exposed in printing position, he momentarily depresses pedal 17, causing the machine to perform one printing cycle (as pedal 101 is held up by spring 110) and then come to a stop as clutch 10 throws out. Next he depresses pedal 104 again, which is thereupon locked down by 20 (parts resuming the full line po- 6), and the machine resumes feeding and skipping cards as be fore. It the operator decidesto over-rule the choice made by the selective device he omits depressing pedal 17 and depresses pedal 10 1 immediately after resetting latch 12 by means of pedal 29 and thereupon the machine starts feeding and skipping again Without any intermediate printing operation.

It the selective device has been set for actuation by. stencil cards which are to be skipped, parts are adjusted as shown in Fig. 7, thus disabling lock 20, and the operator holds down pedal 17. This starts the machine, and as skip pedal 10 1 is held up by spring 110 the machine prints from all cards ted out until one of the class to be skipped reaches printing position. The selective device then energizes solenoid 28 and latch12 is tripped, stopping the machine as before. This also pulls lug 450 over against lug 38 as shown in dotted lines in Fig. 7 The operator then releases pedal 17 (which rises) and pushes reset pedal 29 further down into the position shown in Fig. 8. The lost motion between lugs 38 and 10 having previously been taken up, as above explained, this movement of pedal 29 oscillates resetting crank 36 and resets latch 12 on pin 14. Skip pedal 104 is then momentarily depressed to cause the clutch to make one revolution and then throw out, which causes the machine to eject the card without printing from it. Foot pressure isthentransferred to pedal 17 and the machine resumes feeding and printing as before. If, while the machine is in this adjustment, the operator clecides at any time to overrule the choice made by the selective device and to print from the card arrested in printing position, instead of skipping it as the classification suggests, he depresses pedal 17 immediately after resetting latch 12, and the machine thereupon prints from that card and from succeeding cards until another one of the class which will actuate the selective device comes into printing position.

If desired, when the reset parts are adjusted as in Figs. 7 and 8, the supply circuit for solenoid 28 may be broken and thereafter the machine operated Without automatic selection occurring, the operator merely following the instructions given in the prior Belknap patent, they are ted into printing position and deciding himself, as each comes into view, whether to skip it or to print with it. Skip pedal 29, will, however, have to be depressed after each depression of pedal 104, to tree lock 20, or else it must be fixed in depressed position.

watching the cards as The main advantages of this invention over the construction shown in our Patent No. 1,518,912, arise from the fact that the automaticstoppage of the machine by a selective, or other, device is accomplished without allowing the pedal or pedals depressed to rise suddenly, and that the selective device operates efi'ectively'whether the machine has been adjusted to normally print with, or skip, the cards fed to it. Also, the pivoting of stop lever 98 on front cross bar 23 and having it extend toward the rear of the machine permits the pedal system to be moved back so the operator can sit close to the machine with his feet under it.

The main distinction, so far as inherent advantages are concerned, between the herein described mechanism and that shown in our copending application Serial No. 119,- 826, filed June 1, 1926, consists in the wider range of possible adjustments and results above described.

That is-to say, scribed in our said chine could only be with the mechanism deprior application the maadjusted to run continuously in the skipping phase, any cooperating selective attachment being actuated (and. thereby stopping it) when a card which was to be printed came into printing position. v

If any attempt had been made to reverse the operation of the apparatus of application No. 119,826, and run it in the printin phase by holding down printing pedal 17 until any cooperating selective device was actuated by a card to be skipped and stopped the machine, it would have been abortive be-. cause the raised position of the skip lever described in our said ti OIl S b i g ing from the underlying certain of the appended invention) and all selective action would have been nullified, with the result that the machine would have run on, printing from all cards and simply straining the parts (Without producing any other effect time a, card of the class that should be skipped came into printing position; This was so because oursaid prior application disclosed no means torso adjusting lock arm 20 ,as to put it out of eiiective action. a

The main distinction between the apparatus of our said prior application and that herein described therefore lies in some means (such as described, or its equivalent) for disabling lock arm 20 and thus permitting the machine to be run in printing phase by holding pedal 17 down without at the same time thus nullifying the action of any 00- operating selective device. Another and minor distinction in details of construction arises from the substitution of a different form of detachable trip latch 12, here shown, which totally disconnects pedal 17 from clutch throwout cam member 72 while that a, p i r app o merely permitted a temporary elongation of the link connecting pedal 17 with said clutch throwont 72; the result of the two operahowever, the same both cases. While we have shown and described our invention as applied to an addressing machine of the particular type above referred to, it is evident that modified forms of the invention might be applied to other terms of addressing machines and to other classes of power-driven mechanism whenever it is desirable to automatically stop the same without producing objectionable noise and shock, and this can be done without departprin'ciple of ourinvention as the same has been set forth in claims.
