36. Claims.

This invention relates to strip feeding means, and more particularly to a self contained unit for association with imprinting, punching, recording or writing apparatus and embodying feeding mechanism which is synchronized therewith to intermittently advance continuous series connected forms alternately with the operation of the imprinting or other mechanism by which such forms are operated upon.

' While various forms of friction feed devices have heretofore been employed with stamping and imprinting mechanism and the like such as addressing machines, checkwriters, utility statement imprinters, and analogous mechanisms, such feeding devices are not suitable for modern high speed operation. It is necessary for rapid operation that the material being operated upon shall be positively advanced an exact distance at each feeding movement and arrested in predetermined position after each such operation. There is always some slippage or creep occurring in the operation of friction feed devices which becomes greatly exaggerated as the speed of operation increases. Such feeding error is cumulative and soon results in appreciable offsetting of the impression and the imprinted matterwill not be properly placed on the forms, checks, statements, or other records being produced. As herein disclosed the present invention includes a pin type feeding device having positive engagement with the material being operated,

which may be incorporated in the imprinting apparatus as a component part thereof, but which for illustrative purposes, but with no intent to unduly limit the invention in this respect is herein illustrated as comprising a separate unit. Such feeding device is provided with a driving motor independently of the imprinting apparatus with which it is associated for intermittently operating the feeding device which is timed to complete a full cycle of feeding operation during a portion only of the cycle of operation of the imprinting mechanism and while the imprinting member is retracted. The imprinting mechanism functions to trip the feeding apparatus after the impression has been made upon the strips of series connected forms, whereupon the feeding mechanism will operate throughout a complete cycle before the next impression of the imprinting apparatus. By this means the two mechanisms are properly synchronized but each performs .its particular function independently of the other, one operating through its full cycle in a shorter period of time than the other, or through alternating periods of operation.

1936, Serial No. 106,158

The object of the invention is to improve the construction as well as the means and mode of operation of strip feeding mechanism whereby itmay not only be economically manufactured, but will be more efiicient in use, positive in action, uniform in operation, aiford increased accuracy of registration of the advanced forms and be unlikely to get out of repair.

A further object of the invention is to provide a strip feeding unit which may be operated independently of the imprinting apparatus with which it is associated, but in synchronized relation therewith.

A further object of the invention is to provide a self contained unit which may be operatively connected with various forms of strip imprinting or treating apparatus with equal facility,

A further object of the invention is to provide a positive feeding device having a quick operating timed cycle of operation shorter than that of the mechanism with which it is associated.

A further object of the invention is to provide a continuous operating driving member for the strip feeding mechanism with means for automatically connecting and disconnecting the driving member and feeding mechanism at timed intervals whereby the mechanism will be intermittently actuated through definitely timed periods of operation and instantly arrested with the advanced forms in exact registry with the imprinting mechanism and so maintain an intermediate accurately timed period during which the imprinting apparatus is operated.

A further object of the invention is to provide means which is readily adaptable for feeding different lengths of forms and also to provide for simultaneously feeding different strips of material different distances.

A further object of the invention is to provide improved tripping mechanisms operable by the imprinting, punching, stamping or other apparatus with which the present feeding unit may be associated by which the operation of the feeding mechanism may be automatically initiated and the driving member automatically and instantly disconnected at the end of a predetermined feeding movement.

A further object of the invention is to provide operation of the feeding mechanism at the will of the operator.

A further object of the invention is to provide improved means for adjusting the aligning feed mechanism to insure presentation of the feeding forms in accurately registered relation with the imprinting mechanism.

A further object of the invention is to provide improved guide means for the form strips as to minimize resistance to their feeding movement.

A further object is to provide an independently actuated strip feeding mechanism which may be incorporated as a component part of an imprinting mechanism or operatively associated therewith as a separate unit under synchronized control by the imprinting mechanism.

With the above primary'and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described and set forth in the claims.

For illustrative purposes, but with no intent to unduly restrict or limit the scope or application of the invention it has been illustrated inassociation with an imprinting apparatus known commercially as an Addressograph which comprises a supporting stand I carrying a table 2 from which projects a vertical magazine a containing a stack of printing plates or stencils which are consecutively fed by a reciprocatory feeding slide b automatically actuated in properly timed sequence by motor actuated mechanism 0 located beneath the table 2 whereby the plates are singly presented beneath the depressible pressure head 4, in printing relation with successive portions of a continuous strip 3 of'record material or series connected forms intermittently advanced across the table 2 by the feeding mechanism forming the subject matter hereof, after which the plates are deposited through an opening in the table 2 into a receiving receptacle (1. The printing head 4, is power operated and is timed to engage the strip 3 intermediate succeeding advance movements thereof by the strip feeding unit which forms the subject matter 7 hereof. As shown in Fig. 1 of the drawings, there is mounted upon the table 2 of the addressing machine an elevated shelf or stand 5 to receive a packet 6 of record material or series connected detachable forms and with which ar'e associated guide rollers 1 and 8 about which the material is directed from the supply packet 6 into imprinting position beneath the depressible head 4 and from which the strip is drawn over the table top 2 by the strip feeding unit.

Inasmuch as the addressing, imprinting, punching, or other strip treating apparatus with which the present feeding mechanism may be associated, per se, forms no part of the present invention, the driving and timing mechanism pertaining to the imprinting head 4 has not been illustrated in detail other than to show a dependent arm 9, in Fig. 2, moving in unison with the imprinting head 4 which is utilized in the present instance to transmit tripping motion to the strip feeding mechanism.

The present strip feeding unit forming the subject matter hereof is an independent structure to be removably associated with the addressing machine or any other analogous mechanism for operating successively upon a continuous strip of material to be advanced intermittently past the operating position. The conventional addressing machine illustrated in the drawings is provided with a rod i9 fixedly secured to the table 2 in parallel relation with the margin thereof. Such rod is utilized for locating the strip feeding unit in its operative relation with the addressing machine. However in the absence of such rod other locating and attaching means may be employed.

The strip feeding unit I in its preferred form as illustrated in the drawings, includes a base portion l2 supported uponrelatively short legs |3 from each end of which arise frame standards l4 interconnected one to the other adjacent to their tops by a. transverse frame bar IE to thereby afford a substantially rigid frame structure. At the rear side the frame standards l4 are notched at IE to receive the rod l8 connected in parallel relation with the margin of the table 2 of the addressing machine. Set screws I! in the frame standards serve to removably secure the frame in its adjusted relation with said rod Ill engaged within the slots "5.

Journaled in the end frame or standards l4 and extending transversely of the strip feeding unit is a driven shaft l8 upon which are mounted for axial adjustment longitudinally of the shaft 2. pair of pin wheels l9 and the radial pins of which are progressively engageable in successions of spaced feed holes in the margins of the strip 3. The pin wheel units l9 are mounted for unison rotation with the shaft l8 and are adjustable thereon relative to each other to accommodate such pin wheel feeding devices to strips 3 of different widths and to different paths of travel of such strip 3 across the table 2 whereby the imprinting may be impressed on any desired portion of the strip. The shaft l8 and pin wheel feed devices l9 carried thereby are intermittently rotated in alternation with the actuation of the imprinting head 4 through successive measured cycles of operation suflicient to advance the strip 3 exactly one form length or predetermined distance at each actuation.

For actuating the feed shaft ll in synchronized relation with the operation of the imprinting head 4 there is mounted upon the unit a driving motor 2| which upon closing a switch in the motor control circuit is set in .continuous operation. The motor 2| is coupled with ap'stud shaft 22 one end of which is provided with a bearing in a bracket 23 secured to the inner side of the frame standard ll at the left hand end of the unit as viewed in Figs. 1 and 3. The other end of the driving stub shaft 22 has a journal bearing within a bushing 24 seated in the hub 25 of a disc' 26 which in turn is journaled in a bearing member 21 mounted in the frame standard H. The stub drive shaft 22 being coupled to the drive shaft of the motor 2| rotates continuously. It carries at mid-length a toothed wheel 28 rotating in a plane closely adjacent to the inner face of the disc 26. The toothed wheel 28 is preferably although not necessarily formed integral with the stub shaft 22 and is provided with a succession.

of square notches having parallel sides. Pivoted to the face of the disc 28 is a dog or pawl 29 having a square nose which corresponds to and is engageable in any one of the notches of the wheel 28 to operatively connect the disc 26 with the rotating wheel 28 upon the drive shaft 22 for unison rotation.

To accurately control and time the engagement and disengagement of the dog 29 with the toothed wheel 28 there are provided a pair of

rock arms

30 and 3| disposed respectively in the planes of rotation of the disc '26 and toothed wheel 28.

Each of these

rock arms

38 and 3| is provided.

- frame standard. The rock arm 38 is fixedly connected to a rock shaft journaled in the frame standard It and extending across the unit while the companion rock arm 3| is loosely journaled on said rock shaft 35. The pawl or dog 29 is provided with a shoulder 36 into the path of which the loosely mounted rock arm 3| projects when in a depressed position. The engagement of the shoulder 36 with therock arm 3| as the disc 28 rotates causes the dog 29 to be oscillated out of engagement with the toothed wheel 28 against the tension of a retracting spring 31 thereby releasing the driving engagement between the stub shaft 22 and the disc 26. At the same time the engagement of the shoulder 36 of the dog 29 with the rock arm 3| positively arrests the rotation of the disc 26 and holds it in a predetermined position. The engaged relation of the dog 29 with the toothed wheel 28 during the driving period is illustrated in Fig. 8 whereas in Fig. 10 the parts are shown in disengaged relation with the shoulder 36 of the dog 29 in engagement with the end of the rock arm 3| which forms a stop therefor. When the stop arm 3| is elevated to disengage the shoulder 36 of the dog 29 the spring 31 will draw the latter into engagement with the toothed wheel 28 and the disc 26 will be carried in unison with the wheel 28 until-the shoulder 38 again engages the end of the stop arm 3| whereby the dog will be oscillated out of engagement and the disc arrested.

To eflfect such release of the driving dog 29 for engagement in the notched wheel 28 there is provided at the right hand end of the unittripping mechanism for imparting a rocking motion to the shaft 35. At the right hand side of the unit interiorly of the upright standard H the rock shaft 35 carries a relatively short rock arm 38 connected by a link 39 with one arm of a pivoted bell crank lever 40 mounted in spaced relation beneath the rock shaft 35 upon the inner side of the frame standard M. The other arm of the bell crank lever 48 is upturned into a path of a shoulder 4| upon a reciprocatory bar 42 connected by a link rod 43 with the dependent arm 9 of the imprinting apparatus which oscillates in unison with the imprinting head I;- The reciprocatory bar 42' rides upon a guide roller 4 pivoted to the inside of the frame upright l4 adjacent to which the bar is provided with an inclined cam surface 45. The reciprocatory bar 42 is'yieldingly held in depressed position with its shoulder 4| aligned with the upturned arm of the bell crank lever 48 by a retractile spring 46.

As the imprinting head 4 is retracted after impressing the strip. 3 such retractile movement 15 is transmitted through the dependent arm 9 to the link rod 43 thereby urging the bar 42 toward the right in Fig. 6 and causing engagement of the shoulder 4| with the upturned arm of bell crank lever 40 to effect an oscillatory movement of the bell crank lever which is transmitted through the link 39 to the rock arm 38 secured to the rock shaft 35. As the bar 42 continues to advance under influence of the imprinting machine arm 9 the cam 45 engaging with the roller 44 elevates the bar 42 against the tension of its retracting spring 46 and causing the shoulder 4| to pass over the top of the engaged arm of the bell crank lever 40 thereby releasing the bell crank lever and allowing the latter together with the link 39 and rock arm 38 and the rock shaft 35 on which the arm 38 is mounted to return to normal under influence of the retractile spring 32 connected to the rock arm 30 which as before stated is fixedly secured to the rock shaft 35. The rock arm.3|l is provided with a laterally extending lip or extension 41 which projects heneath the loosely pivoted stop arm 3|. Upon oscillation of the rock arm 36 incident to the rocking movement of the shaft 35 as before mentioned the stop arm 3| is lifted therewith out of engagement with the shoulder 36 of the dog 29 thereby permitting the latter to reengage the notched wheel 28. The rock arm 30 also carries a roller 49 which rides upon the periphery of the disc 26 until it encounters a notch or depression 59 therein as the disc completes one ccmplete rotation or a half rotation as will be later referred to. So long as the roller 43 is riding upon the periphery of the disc 26 the stop arm 3| is held in elevated position out of the path of. the shoulder 36 of the dog 29. However as the disc completes its rotation the roller 49 drops into the notch or depression 50 and thereby allows the stop arm 3| to descend under influence of its retractile spring 32 into the path of the shoulder 36, the engagement of which with the stop arm serves to oscillate the dog 29 out of driving engagement with the notched wheel 28 and the disc and associated parts will come to rest. The disc 26 is thus intermittently actuated through a complete rotation, or through a half rotation as hereinafter mentioned, and positively arrested at the end of such movement. This accurately measured movement of the disc 26 synchronized with the actuation of the imprinting apparatus is transmitted to the feed shaft l8 and pin wheels l9 through a suitable gear train. Such gear train as is illustrated in Fig. 5 includes a driving gear pinion 5| secured upon a reduced portion of the hub 25 of the disc 26 at the outer side of the frame standard I4. The gear pinion 5| intermeshes with an idler pinion 52 carried upon a swinging arm 53 mounted concentric with the feed shaft l8 and intermeshing with a driven gear pinion 54 upon such feed shaft. The pinion carrying arm 53 includes a slotted segment portion 55 within the slot of which engages a clamp bolt 56 to secure different Widths.

may be actuated at different speeds to enable the advancement of the strip 3 different form lengths during'a given time interval between succeeding impressions of the imprinting head 4. Whatever the lengths of the forms may be or whatever distance it is desired to advance the strip 3, such movement must be effected during the time interval determined by the operation of. the im printing apparatus. Therefore to advance the strips greater distances to accommodate increased lengths of forms the speed of the feed shaft and pin wheels must be correspondingly increased by substitution of a driving pinion 5| of proper size.

For feeding half length forms known as split tickets the rocker arm and stop arm construction by which the engagement and disengagement of the dog 29 is controlled may be duplicated at the opposite side of the disc as is shown in Figs. 8 and 10. The

arms

36 and 3| and retractile spring 32 are duplicated in reverse, relation as indicated at 30a, 3|a, and 32a. The rocker arms 3| and 3|a are interconnected for unison movement upon oscillation of the rock shaft 35 by an interconnecting link 60. The link 69 has a slotted connection with the rocker arm 30a enables the arm to be held in an inoperative position against the tension of its retractile spring 320, by a manually adjustable cam member 6| mounted in the bracket 23. By adjusting this cam member 6| from the position shown in .Fig. 8 to the full line shown in Fig. 10 the auxiliary control devices are held depressed against the retractile tension of the spring 32a and are ineffective upon half rotation of the disc 26. However when released for operation as shown in Fig. 8 the roller 49a carried by the arm 36a enters the depression 50 in the margin of. the disc 26 when said disc has made a half rotation thereby allowing the stop arm 3|a to project into the path of the shoulder 36 of the dog 29 the engagement of which with the stop arm effects the disengagement of the dog from the notched wheel 28 and thereby arrests the disc at the end of a half rotation. The operation is otherwise as before de scribed and the half rotation of the disc 26 is transmitted through the gear train to the feed shaft l8 and pin wheels I9 to advance the strip 3 a lesser distance than thateffected by complete may be utilized for feeding either a single strip 3 or for feeding multiple superposed strips upon which the impression is manifolded by the imprinting apparatus. wheel members l9 in the registering feed holes 26 of superposed strips will feed such strips in unison. A suitable receiving compartment is preferably provided upon the base l2 of the unit to receive the advanced portion of the strip or strips. To meet certain conditions of use it may be desirable to manifold the impression upon strips which are advanced differentially. For example the impressions may be widely spaced upon one of the strips a form length apart 6 whereas the same impressions may be produced upon an accompanying strip in more closely spaced relation for tally or checking purposes. Such superposed strips may be of the same or In the event that a differentially travelling strip is desired brackets 62 may be provided for attachment to the frame upright l4. Suitable bearings are provided in the bracket 62 for a secondary feed shaft 63 which carries The engagement of the pin additional pin wheel feeding devices 64. This auxiliary feeding shaft 63 and pin type feeding devices 64 are substantially duplicates of the feed shaft l8 and the feeding devices I! but are arranged in offset parallel relation therewith. Such auxiliary feeding device is actuated through a suitable gear train from the driving pinion 5| as is shown in Fig. 5.. In this instance an idler gear 65 carried upon an adjustable carrier arm 66 intermeshes with the driving pinion 5| and in turn drives a gear pinion v6'! concentric with the carrier arm 66. The gear 61 meshes with a gear 68 which in turn intermeshes with a gear 69 upon the auxiliary feed shaft 63. The gear 65 is removably carried. upon the swinging arm 66 and other gears of different size may be interchanged therewith to vary the speed ratio of the auxiliary feeding shaft 63 and pin wheels 64.

For the purpose of holding the strips 3 in a fiat plane of travel and prevent buckling guide bars 10 are provided which extend in overlapping relation with the margins of the strips. The guide bars I0 are adjustably mounted upon rods H extending transversely of the frame and are curved at their forward ends substantially in conformity with the pin wheel feeding devices l9 and 64. These guide bars 18 are slotted coincident with the feeding devices to provide clearance for the feeding pins which project through the holes in the strip 3 and thence into the slots of the guide bars 10. These guide bars therefore loosely retain the strips in engagement with the pins without, however, imposing thereon any friction or restrictive pressure which would tend to retard the advancement of the strips. Throughout their length the guide bars III are provided with laterally extending ears I2 which are depressed slightly out of the plane of the bars and rest upon the surface of the table 2 of the imprinting apparatus to hold the bars in slightly elevated relation above the plane of travel of the strip 3 to minimize frictional resistance thereto. As the pin type feeding devices are adjusted to and fro on the feed shafts l8 and 63 to accommodate material of different widths the guide bars 10 are correspondingly adjusted on their rods H in registry with the feeding devices and in overlapping relation with the margins of the strips.

In lieu of elevating the guide bars 10 to minimize friction and resistance to travel of the strips thereunder, such guide bars may be of aluminum fiber or other relatively light material which may be permitted to rest directly upon the travelingv strips without exerting appreciable retarding influence thereon.

In the event that it is desired to sever the imprinted forms as they are advanced past the feeding devices a cutting or breaking device may be associated with the feeding unit as is shown in Fig. 2. To support such cutter, a pair of interconnected spaced parallel rods I3 project horizontally from the upright frame standards ll upon which is adjustably mounted a cutter head 15. The cutter head 15 embodies a vertically movable knife 16 which may be operated either mechanically from a moving part of the feeding unit or may be operated by electromagnetic means controlled by the operation of the timed feeding mechanism to shear the imprinted forms upon predetermined division lines or in event the strip 3 is provided with transverse weakened lines this cutter may be adapted to break the strip upon perforated or otherwise weakened division lines thereof. I

While various operating means may be employed for mechanically actuating the cutoff knife 16 in timed relation with the operation of the imprinting and feeding mechanisms there is shown in Fig. 2 a lever shaft 86 which carries at its opposite end a rock arm 85a corresponding to the upper arm of the lever 85. The upper end of the lever 85 and corresponding rock arm 8511 extend beneath studs 81 carried by the vertically movable knife I6. Upon oscillation, the lever 85 elevates the knife against the resistance of a retracting spring 88 to permit the form strips to be advanced beneath the knife by the feeding devices.

The knife elevating lever 85 extends into the path of an extension 89 upon the reciprocatory trip bar 42. 42 by the actuation of the imprinting apparatus oscillates the lever 40 to trip the strip feeding mechanism and by the same advance movement it oscillates the lever 85, to elevate the knife and hold it in its elevated position until the trip vbar 42 is again retracted. In the mean time the feeding mechanism will have been operated through its complete cycle which is of relatively short duration and the record material will have been advanced a form length beyond the plane of the knife 16 which upon its descent will sever the advanced portion of the strip.

In lieu of the mechanical actuation of the cutoff knife 16 electro-magnets or solenoids 96 may be employed to retract and hold the knife in its elevated position. The magnets or solenoids 90 are included in an electrical circuit 9| having therein a circuit breaker comprising contacts 82 controlled by the trip bar 42. Upon advancement of the trip bar 42 under influence of the The advancement of the trip bar imprinting apparatus, the contacts are permitted to separate, thereby opening the circuit and permitting the cutoff knife to descend. The circuit is again closed by the retraction of the trip bar thereby re-energizing the electro-magnets 90 to retract the knife 16 preparatory to the next operation.

Any form of motor drive may be employed. While the feeding device may be actuated from a motor common to the imprinting mechanism of the addressing machine or associated apparatus. While the stub drive shaft 22 of the strip feeding apparatus may be driven from a motor mounted on the imprinting or other associated mechanism and common to such associated apparatus and the strip feeding mechanism there is preferably provided a separate driving motor mounted on the strip feeding mechanism and driving such feeding devices wholly independently of the imprinting apparatus. The relative position of the motor is illustrated in Figs. 3 and 4. The motor shaft is preferably driven at a somewhat reduced rate of rotation by suitable reducing gear mechanism within the gear box 11 connected with the motor casing. The motor casing and gear box are provided with perforate mounting arms 18 for engagement of short supporting shafts 19 projecting inwardly from the frame upright. The head of the motor drive shaft is slotted at 80 for clutch engagement with a corresponding key or rib 8| upon the stub shaft 22 of the feeding apparatus.

In the relation of the feeding mechanism and the imprinting apparatus illustrated in Figs. 18 and 19 the strip feeding mechanism is the same as before described, but is mounted in a frame 82 of modified form which is adapted to rest upon the table of the addressing machine immediately over the imprinting apparatus in lieu of the supply packet stand shown in Figs; 1 and 2. In such arrangement the supply packet is located in a holder 83 at the front of the imprinting apparatus table in the position occupied by the strip feeding mechanism as shown in Figs. 1 to 4. The strip is drawn therefrom in a reverse feeding direction across the table and under guide rollers 84 and thence to the strip feeding mechanism forming the subject matter hereof, mounted over the imprinting means. That is to say the strip supply holder and feeding mechanism are transposed and the strip advanced in a direction reverse to that previously described.

In such position over the imprinting head, the motor driven feeding mechanism is tripped in synchronism with the imprinting apparatus in quite the same manner as before described. As is shown in Fig. 19 the link 39 connected with the rock arm 38 is somewhat elongated, and connected at its lower end to a trip arm 40a pivoted to the frame upright l4, having at its extremity a shoulder which projects into the path of a coacting shoulder Ma upon a reciprocatory trip bar 420. connected with a suitably moving part of the imprinting mechanism whereby the operation of the strip feeding mechanism is initithe associated guide rollers I and 8 and past the imprinting position by the feeding mechanism as before described.

From the above description it will be apparent {that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the.

principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into efiect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
