This invention relates to apparatus for severing the different record sheets of a continuous multi-formandseparating the sheets from their interleaved carbons- It is customary to'make -multiple form'sheets for use as bills, invoices, purchase orders, 'shipment records, etc.,- as -long, continuous record strips interleaved withcarbon papers so that the record sheets may be typedserially as multiple copies and later to becutapartandseparated from the carbons- The multiple forms have been perforated at their margins for feeding'them through tabulatingmachines ortypewr-itei'ss One type of multiple form, such as. one havingsix record sheets and five-interleaved carbons, 'hasbeen made of three folded sheets tacked togetherat the folded margins, and thecarbons have been securedto the record sheets by adhesive applied at the same margin, so that all ofthe papers-of the multiple form are secured together atone margin, such as at the right hand side, and they The primary object of this invention is .to'over-- com'e such problems and providelapparatusiwhich will feeda continuous 'inulti form'to a requiredi position where the forward set of record sheets is severed from. the remainder and the vIint'erileaved carbons are pulled at'leas't lp'artiallyffrom" their interleaved positions.

:In accordance with this invention, I have provided apparatus for severing and bursting a continuous multi-form having interleaved narrower carbons connected together by a marginal strip. That strip is .severable from the main portion of each record sheet along a row of perforations or other type of a line of weakness which insures bursting along this line by a laterally applied force. .The multiplex paper form is fed forward by a drive mechanism, which, as illus-' trated, may be operated by hand. In the preferred machine, a rotary cutter severs the lefthand carbon free margin as the multiple form is fed forward. Thereafter, a transverse cutting knife, is operated, preferably by a foot treadle, to sever a single set of record sheets and their carbons from the continuous form. The carbons are then burst from their interleaved po-v sitions. by mechanism which grips the record sheets near their opposite margins and pulls laterally. The right-hand marginal strip is attached to the interleaved carbons so that as the multiple form is burst along the perforated lines, the carbons may be pulled out. These operations are accomplished by manually controlled mechanisms which are preferably manually operated.
vReferring first to Figs. 4 and 5, one standard type of continuous multi-form having connected sets of record sheets interleaved with carbons comprises folded sheets of paper I interleaved with carbon papers 2 arranged for desired typing purposes. The drawings show three folded record sheets and five carbons. Each carbon paper has a glued margin 3 secured to an associated record sheet, and the three folded sheets are tacked together by adhesive as indicatedat 4, so that the record sheets and carbons are secured together at the right-hand margin 8, as seenby a person stationed at A in Figs. 1 and 4. The margins are provided with lines of weakness, such as spaced or dotted perforations 5 at the left and B at the right along which the marginal strips 7 and 8 may betorn away from the main body ofeach record sheet. Each carbon sheet isnarrower than the record sheet so that the outer left-hand edge 9 of each carbon sheet is spaced inwardly from thetear line 5 at the left. Hence, the record sheets may be gripped by the member. 1!! (Fig.4) outside of the carbons after the left-hand margin strip 7 has been removed. The left-hand margin strip '1 is removed by cutting the paper along the line 5; and, of course, a line of perforations is no longer needed. After the strip I has been cut away, the next step is to burst the carbons from their interleaved positions. This is done by tearing or bursting the'record sheets along the righthand line of weakness 6, and removing the multiple strip 8 carrying the carbons attached thereto. This serves to pull the carbons from their interleaved positions.
The apparatus of the present invention is intended to perform these various operations mechanically. The mechanism shown in Figs. 1 to Y 3 and 6 to 11, inclusive, comprises a table top or platform l2 suitably mounted on standards such as the legs [3. (Fig. 3). The continuous strip is adapted to be fed transversely of the table in the direction of the arrow (Figs. 1 and 4) by means of drive wheels engaging the paper, such as rollers or preferably sprockets l4 and I5 which are operated by a drive mechanism. As illustrated, the sprockets have radial teeth engaging a suitable line of perforations 16 parallel with and spaced from the two margins of the multi-form. These sprockets are mounted on a driven shaft I'I suitably supported in bearings on the machine frame. The sprocket or drive wheel 15 is adjustably mounted on the shaft I? so that it may be moved axially to provide for different widths of the multi-form. This may be done by providing an adjustable set screw in the hub of the sprocket l5 which may be set against the outer surface of the cylindrical shaft H.
The shaft I! may be turned by a power drive mechanism, and this is preferably accomplished by means of a manually operated device comprising a flexible tape is (Figs. 1 and 6) wrapped around and fixed to a drum is which in turn is connected to the drive shaft l! by a pawl 20 pivoted on the drum flange and releasably engaging a ratchet wheel 21 on the shaft I] (Fig. '7). A coiled spring 23 (Figs. 1 and 8) suitably secured at one end to the side of the table 1-2 has its other end fixed to the drum [9 and tends to wind the flexible tape 18 on the drum. The tape is manually drawn in the opposite direction to rotate the drive sprockets l4 and [5 by means of a handle 24 suitably mounted on a slide 25 which rides on a metal strip 26 secured to the side of the machine. A coiled spring buffer 21 surrounding the strip absorbs the impact of the slide 25 when the handle and slide are drawn towards the left (Fig. '1) by the spring 23. An adjustable U-shaped stop 23 is suitably mounted on the slide support 26 so that the slide carriage 25 may be moved only to a required position to locate the paper properly. This stop may be adjusted along thesupport and held in a desired position bya set screw 29 passing through the stop and clamping it against the strip 26. Thus, by means of this manually operated slide member 24, the drive shaft IT and its associated sprockets l4 andv l5 move the continuous strip towards the right in Fig. 1 to a required position, so that the line 32 on which the multiform is to be severed may be brought correctly beneath a transverse cutting knife. corresponds with a row of perforations, now unnecessary for. the cutting operation, which have been provided to assist the operator in severing the fan folded strip, but the line 32 may be creased or perforated to aid in forming the fan fold.
That line A preferred cutter structurefor severing the left-hand marginal portion 1 comprises a rotary cutter knife mounted on a short shaft 36 (Figs. 1 and 9) and co-axial with drive gear 31 which meshes with a drive gear 38 fixed on the shaft IT. The cutter 35 is so positioned that it will sever the left-hand marginal strip 1 along the line 5 and as indicated by the slot 39. (Fig. 4.) Thus, as the continuous strip is fed toward the right, that slot 39 is cut through all of the sheets of the multi-form and the marginal strips 1 thereof are severed automatically. The carbon papers are narrow and terminate at the line!) of Fig. 4 and so are not cut by the rotary cutter. This rotary cutter may be mounted on alever 40 (Fig. 9) pivoted at 4| on the standard l-2. This. permits the cutter to .be swung out ofthe way when the continuous multi-form is to be inserted in the machine. locking cam or lug 43 is pivoted at 44 on. the table I2 and so arranged that the lug 43 engages thetop surface of the. bearing mount of the cutter and thus holds the cutter down against the. paper. sheets during the cutting operation. The paper srip is held in driving engagement with the. sprockets 4 and I5 by means of two slottedVL-shaped plates 46 having slots in the horizontal portions through which the .drive sprockets project. The vertical sides of the-plates are pivotally mounted on short screws 41 carried by the blocks 43 on the table top l2. A spring may be provided to hold each plate down against the paper so as to insure that the sprocket teeth of the drive wheels will pass throughthe perforations l6 of the papers and feed the same properly.
Each set of records of the multi-form is separated 'from the continuous sheet by a transversely acting cutter, which is preferably constructed as a suitably shaped reciprocable blade 50. (Figs. 1, 2 and 3.) The blade is removably mounted on an arm 5| that is pivotally carried on a pivot pin 52 suitably mounted in a bearing on the top of the table l2. The blade cooperates with a, stationary knife 54 set fiush with the table top, a groove being provided in the table to receive the blade 50. To insure that the two edges make an accurate contact at the point of cutting, the blade carrier 5| has its pivot support made laterally movable and urged towards the left (Fig. 1) by a coiled compression spring 55 suitably mounted on the pivot post 52. The free end of the blade mount 5| rides between the two spaced standards 56 mounted on the table. (Fig. 3.) A roller 51 is rotatably pivoted on a pivot carried on the mount 5| and arranged to roll against the inner plane surface of the front standard and press the knife 50 back against the stationary blade 54 as permitted by the spring 55. Various constructions may be employed to serve the purpose.
The reciprocable blade 50 is moved down to out the paper by suitable mechanism, and preferably by the foot treadle 60 (Fig. 3) carried on a swinging arm 6| secured to a rock shaft 62 mounted on the framework. A spring 63 urges A lever 42 havingathe foot treadle 60 towards an uppermost position. The treadle 6|] is pivotally connected by a draw rod 54 to an extension arm 65 secured to the top of the blade support 5|. A screw 66 fixed in the end of the member 65 and loosely projecting through a pivot hole in the draw arm 64 serves to draw down on the cutter blade 50 when the treadle 60 is operated. A spring ing sted. ban ing. P13 9 21 i s arm 5!..
and fixed to the table at its other end cooperates to hold the cutter in an uppermost position when the foot treadle is released. Thus, by means of the rotary cutter 35, the left-hand marginal strip 1 of the continuous multi-form is removed and the forward set of record papers and their.
carbons are severed from the multi-form by the knife 50, as shown at the right-hand side of Fig. 4. After the cuttingoperations, the next step is. that of separating the carbon inserts from the.
ribbon and carbon copies of the typed material. This. is done mechanically by means of the relatively spreadable paper grippers shown primarily in Figs. 1, 3, 10 and 11, which are preferably caused to grip the multi-form in a timed rela-. tion to the transverse cutting operation, as may be accomplished. by having the transverse cutting secured on an angle iron on the side of the arm 5| with the blade teeth arranged parallel with the perforation line 5 but outside of the carbon paper line 9, as shown particularly in Fig. 4, .so.
that the gripping blade .10 engages the main body of the multi-form but not the carbons or the marginal strip I which has been severed by the cutter 35. The teeth bite through the top sheet enough to hold all of the record papersheets securely against the table top I2, and yet leave the short carbons free to be removed. Removal.
of the carbons is accomplished by tearing orrupturing the various record sheets. of paper along the perforated line of weakness 6, which was initially provided on the multi-form. While the member 10 is held in gripping engagement with the papers by holding down the foot treadle, the operator may grasp the righthand margin-8 and tear off that marginal portion with its appended carbon papers.
This bursting of the carbon supporting margin 8.,from the record sheetsis preferably accomplished by the mechanism shown in the drawings. so that the major efiort of rupturing the paper is accomplished mechanically. To this end, I
have provided a slide 14 on a stationaryplate i6 fixed in the recess 15 in the table top. .The slide moves transversely at a suitable angle to themargins of the papers. The plate may be T-shaped and the slide 74 provided with suitable flanges which grip theunder side of the vT memher and so hold the slideplate in place, or other,
cured thereon and carrying a roller 82, the axis of which is at right angles to the blade 50. The roller is so positioned that when the knife blade is brought down to cutv the paper, the roller thrusts the upper plate member 11 downwardly against the pressure of a compression spring 84 (Fig. 10) arranged between plate 1! and the roller slide 74. The relatively pivoted members are so spaced and the roller is of such a size that when the knife 50 is in its lowermost position, the
roller 82 holds the pins in firm gripping engagement with the right-hand margin 8 of the paper to which the carbons are attached r 1A a l ve 8. is. piv tal y connected at .81 to.; tbe ide..;
7 of the slide block 14, and the lower portion of this lever projects through a narrow slot 88 in the table top (2, the sides of which serve as a fulcrum for the lever. A spring 89 engaging an extension of the lever below the fulcrum slot tends to hold the slide in a left-hand position. If the handle of the lever 85 is moved towards the right, the bottom portion of the lever fulcrums against an edge of the slot 88 and causes the slide to move transversely to rupture the papers. The slide may move at such an angle as to tear the papers progressively. This is done while the foot treadle 59 is holding the cutter knife St in its lower position. At this time, the paper strip is gripped by the sharp teeth 88 perforating the strip 8 at 90 (Fig. 4) where the teeth press also against the carbon gummed strips 3. Simultaneously, the other teeth iii engage the left-hand strip between the lines 5 and 9 (Fig. 4) and do not hold the carbons. is thrust toward the right, the margin is torn away from the main body of each record sheet of the multi-form, and the paper is ruptured along the line 8. The hinged plate ll and slide 14 may extend only for a short distance towards the right as shown in Fig. 1, but, if desired, this gripper plate may be arranged to contact with the paper throughout substantially its entire length, so that the margin 8 is torn away from the main body of each paper sheet throughout its entire extent. In the form shown in the drawings, the operator has merely to grasp the left margin between the lines 5 and 9 and the righthand margin 8, after releasing the cutter E6 and. the gripper teeth 8%, and pull the carbon secured margin 8 away from the typed ribbon and carbon copies of the record.
In the modification shown in Figs. 12, 13 and 14, I have provided two pivoted reciprocable blades for cutting the paper in the two directions. In this construction, the blade 59 and its swinging arm support 5! are made the some as above described. .In place of the rotary cutter 35, I employ a second reciprocating blade Hill which is constructed and mounted the same as are the corresponding parts 53 and 5!. The pivot I82 for the arm mi is located at the front left-hand corner of the table 12, it being noted that the operator sits at A on the right-hand side of the machine and faces towards the cutter 52, just the same as for the construction of Fig. 1. These two pivoted knives cooperate with a stationary L-shaped knife iii-i arranged at the near side of the transverse slot in the table into which the blade 56 extends; whereas in the other construction it is preferred that the stationary blade at be located at the far side of that slot. The blades 58 and 100 have such dimensions and shapes that they just come together at their ends and so sever the paper in an L-shaped cut. The blade 53 is operated as before by the treadle rod 5 engaging a projection 65 on the blade support 51. The other blade support H)! has a similar projection I96 riding beneath the arm 65, so that when the latter is drawn down it strikes the part it? and forces the blade its downwardly into the paper. Other constructional details, as above described, may be employed with this modification. The blade I93 is urged upwardly by a spring H18, and it may be moved by a cam or guided as above described so that it rides closely against the stationary blade 104 at the point of cutting into the paper.
'The operation of the apparatus will be apparent from the above description. The continu- I-Ience, when the lever 35 paper by means of their spring 85.
our; multi-form made up of the connected interleaved record sheets and carbons is usually fan folded so as to form a pile of the copies in parallelis'm. It can be mounted on a roll, if desired. The free end of the continuous strip (Figs. 1, 4 and 5) is moved forward in the direction of the arrow so that the holes I6 thereof engage the teeth of the two sprockets i l and i5. Previous to this, the plates 38 and the rotary cutter 35 will have been moved out of the way, so as to permit proper manipulation of the paper. After the contact plates it have been lowered to hold the paper in place on the two drive sprockets, the cutter 35 is swung down by means of its pivot arm ii) and the cam lock 43 (Fig. 9) is engaged to hold the cutter in cutting contact with the paper. Then by grasping the vertically projecting handle 2 on the flexible strip guide, the strip 18 is pulled forward and so serves to rotate the associated drum i9 and turn the spindle I! and thus rotate the drive sprockets and move the paper forward. If a stop 28 is used, this will have been previously set to a desired position, so that, when the slide 25 contacts with it, the line 32 between two sets of record sheets on which the papers are to be severed is exactly beneath the cross knife 59. If for any reason the line 32 is not in proper position, then the shaft I? may be rotated through a short distance by means of a knob H on the projecting end of the shaft 51. During this forward feed of the paper, the cutter 35 will have cut on the left-hand marginal strip on the line 5, and that strip may fall through a suitable opening in the platform it into a waste receptacle. The operator then presses on the foot lever 60 and draws the blade 59 downwardly with sufiicient force to sever the paper entirely across. At the same time, the presser teeth 7B are presse into biting engagement with the paper between the iines 5 and 9. The operator holds down on the pedal 69 and then with a quick movement thrusts the hand lever 86 towards the right and bursts the paper at Hi! along the line 6, as shown in Fig. 4. During this action of severing the marginal strip 8 by tearing on the perforated line 6,
the roller 32 holds the teeth BE in biting engagement with the strip 8 which carries the carbons so that, when the slide 84 and the teeth 8i! move toward the right, this marginal portion necessarily goes with it and thus tears the paper apart along the perforations 5, as indicated at H0 in Fig. 4. Thereafter, the operator releases the foot treadle and the knife 53 springs upwardly and the teeth 89 are likewise withdrawn from the The operator then grasps the muiti-strips by their left and right-hand margins and pulls them apart, the typed copies being held in the left hand and the assembled carbons and associated marginal strip 8 are pulled out at the right and discarded.
It will now be appreciated that various modifications may be made in the above described apparatus so that the parts may be operated mechanically but under the operators control to accomplish the desired ends and that equivalent or other mechanisms may be employed. Hence, the above disclosure is to be interpreted as explaining the principles of the invention and describin preferred embodiments thereof but without imposing limitations on the appended claims.
