Eritrean, Cieveland Ave, McDaniel Heights, Wilmington, Del. Filed May '7, 1964, Ser. No. 365,627 14 Claims. (Cl. 225-101) This invention relates to an apparatus for severing multiple ofiice forms and, it more particularly relates to an apparatus for bursting such forms incorporating interleafed carbon paper.

Multiple ofiice forms such as order blanks or invoices usually have sheets of carbon paper interleafed and bound between one side of edge folds. A row of partly severed seams are provided between the carbon bound edges and the main portions of the sheets to permit breaking of the seams to remove the carbons in a group. After the pertinent information is typed upon them, the row of partly severed seams must be completely broken to remove the carbon papers from the remainder of the forms. Heretofore this operation has been performed by hand. This is arduous, tedious and time consuming, especially when there are a multiplicity of sheets to tear through and particularly for weak female hands.

An object of this invention is to provide a simple and etficien-t apparatus for quickly and conveniently bursting the seams of multiple carbon otlice forms with a minimum of effort.

A further object is to provide such an apparatus which is adjustable for accommodating a wide variety of ditierent sizes of multiple carbon office forms.

In accordance with this invention a pair of clamps engage and securely grasp opposite side edges of the multiple forms. The engaged clamps are then moved laterally .away from each other to completely burst through the row of seams between the carbon bound edges and the main portions of the sheets. After the clamps are released, it is a simple matter to remove the severed carbon papers in a group from in between the multiple typed sheets together with the severed stub edges of the forms within which they are bound.

The clamps may be levers pivoted upon laterally movable base plates connected through a linkage to a drive mechanism. The use of a series linkage for engagement of the side edges of the forms between the clamps and their base plates and subsequent lateral movement simplifies the apparatus and insures a firm grip on the grasped side edges of the form as the clamps are moved laterally apart. The drive mechanism may be a rotatable handle which causes a pair of opera-ting rods in the linkage to push outwardly against the driven ends of the lever clamps to first engage the clamps and then move them apart.

In using the apparatus, the side edges of the forms are first inserted between the open clamping levers and base plates. The operating handle is then rotated to push the rods apart and rotate the levers to clamp the edges of the multiple forms against their base plates. Continued rotation of the handle maintains the levers clamped against the grasped forms while the plates are moved laterally apart. This positively maintains a firm grip as the seams between the carbon bound edges of the forms and the remainder of the sheets are burst to facilitate the removal of the carbon en masse with a minimum of eit'ort.

In a simple advantageous form of this invention, the operating linkage includes a pair of bell cranks connected to a rotatable operating handle. This operating linkage may be manually or power operated, such as by an electric, pneumatic or hydraulic mechanism.

In an adjustable form of this invention, the linkage includes a cam and adjustable follower. One of the 3,l@,5lti Patented June 22, 1965 follower rods is adjustably secured to a lever on an adjustable base plate, and its effective stroke and the initial position of the base plate are adjusted in accordance with the width of the form to be burst. A single .series type grasping and lateral moving linkage can thus also be used for bursting the seams of multiple carbon forms of a wide variety of sizes. The clamps may accordingly be mounted at opposite sides of a table which receives the body of the form, and only one clamp need be movable to perform the required functions.

Description FIGS. 1-3

In FIGS. 1-3 is shown an apparatus 16 for bursting multiple ofiice forms 12 incorporating interleafed carbon paper -14. Apparatus d ll incorporates a base frame 16 upon which a substantially fiat table 18 for receiving forms i2 is mounted. A pair of clamps 29 are mounted upon apparatus til at opposite sides of table 18 for grasping and pulling laterally upon opposite side edges 22 and 24- of multiple forms 12. Clamping assemblies 29 include lever means 26 rotatably mounted upon base plates 28. Base plates 28 extend a considerable distance toward each other to provide the major portion of table it The central portion of table i3 is provided by bar 3t in the center thereof. The rotatable mounting of levers 2t; upon base plates 2% is accomplished by brackets 32 and pivot pins 34. Clamping bars 36 are attached at the ends of the substantially horizontal legs 3% of levers 26. As shown in FIG. 2, the substantially vertical legs 40 of levers 2s extend below base plates 28 into the interior of base frame 16.

An operating linkage 42 is connected to lower legs 49 of levers as for connecting the drive provided by operating lever 45 to actuate clamps 20 to grasp opposite side edges 22 and 2d of forms 12 and then move relatively laterally away from each other as later described in detail. Linkage 4. 2 is of the bell-crank type, and operating lever 4-6 rotates in a horizontal plane.

A movable means 48 includes capscrew and nut assemblies 58 which are connected to base plates 28 and extend through slots 52 in upper plate 54 of base frame 16.

This permits the relative lateral movement of clamp assemblies in response to the last phase of actuation of operating lever 46 through linkage 42 as later described in detail.

Linkage 42 is of the bell-crank type as shown in bottomplan view, FIG. 3, and it includes a crank 56 rotatably mounted by pivot pin assembly 58 below central bar of table 18. Lever 46 is secured to crank 56 to rotate it. A pair of actuating rods 60 are rotatably connected to crank 56 by pivot connections 62. The remote ends 64 of rods 60 are freely connected to lower ends 66 of lower lever legs by motion-accommodating connections 68 that accommodate the arcuate movement of lower lever ends 66 to the substantially planar movement of rods 60. Motion-accommodating connections 68 include a slim end 70 of rod 60 extending through a venturi-shaped hole 72 in lower lever end 66. Hole 72 incorporates a pair of outward tapers that permit lower lever end 66 to move through an arcuate path without causing a strain upon the planar orientation of rods 60.

Linkage 42 is of the series type because it includes the movable connection between clamps 20 and base frame 16 which permits the clamps to be moved laterally apart after clamping bars 36 are moved downwardly into engagement with side edges 22 and 24 of forms 12 and maintained firm engagement with the forms, as clamps 20 are then moved relatively laterally apart by further movement of lever 46 applied through linkage 42 to urge base plates 28 of clamping assemblies 20 away from each other. The use of series linkage 42 illustrated in FIGS. 1-3 greatly simplifies apparatus 10 and insures a firm grip on the side edges of forms 12 as the clamps 20 move through the critical part of their bursting motion laterally apart from each other.

A resilient means 74 shown in FIGS. 2 and 3 including spring 76 and pins 78 extending through slots 80 in upper base frame plate 54 biases plates 28, linkage 42 and lever 46 to the unactuated condition shown in FIG. 2 when lever 46 is released.

Guide surfaces are provided by angles 82 mounted about the periphery of table 18 for delineating the area for receiving multiple forms 12. Multiple forms 12 are shown in detail after bursting in FIG. 1A. They include two rows of perforations 85 on side edges 22 and 24 for securing them in a binder. Clamping bars 36 in FIGS. 1-3 include rows of teeth 87 for securely grasping side edges 22 and 24. However, such teeth are not absolutely necessary as indicated in the other form 10A of this apparatus later described in conjunction with FIGS. 4-11.

As shown in FIG. 1A, form 12 includes a number of information bearing sheets of paper 86 whose right-hand stubs 88 are connected thereto by a row of seams 90 shown burst in FIG. 1A but which prior thereto are detachably joined to each other by strips 92 between severed portions 94 that facilitate the bursting of seams 90. Sheets of carbon paper 14 are bound between side edges 24 of stubs 88. This facilitates removal carbons 14 en masse from between sheets 86 of forms 12 when row of seams 90 is burst on apparatus 10 shown in FIGS. 1-3.

Operation FIGS. 1-3

An intact multple office form 12 is placed on table 18 of apparatus 10 when clamps 20 are in the unactuated raised condition shown in FIG. 2. Lever 46 is then rotated in the clockwise direction as shown in FIG. 1 by arrow 96. This first rotates upper lever legs 38 downwardly toward table 18 to engage clamping bars with side edges 22 and 24 and to insert teeth 87 within holes 85. This engagement is accomplished during a first phase of movement of lever 46. As lever 46 moves into its final stage of movement, it reacts against clamping assemblies 20 to maintain clamping bars 36 firmly engaged against side edges 22 and 24 to maintain them firmly grasped between clamping bars 36 and base plates 23. Then continued movement of lever 46 causes linkage 42 including slotted connections 48 to move base plates 23 with the rest of clamping assemblies 20 relatively laterally away from each other to burst row of seams between the main-sheet portions 86 and stubs 88 within which carbons 14 are edge bound. This pulls edge-bound carbons 14 laterally away from in between sheets 86. Carbons 14 are thereby pulled a short distance out of insertion between sheets 86 as shown in FIG. 1 by the slightly withdrawn position of left-hand edge 98 of carbons 14 and the exposed portion of carbons 14 shown adjacent the right-hand clamping bar 36.

When lever 46 is released, spring 76 causes the apparatus to return to the position shown in FIG. 2 in which clamping bars 36 are disengaged from side edges 22 and 24. It is then a simple matter to complete the removal of the carbons and stub edges 88 within which they are bound from the remainder of form 12. Any female oifice worker can easily complete the process, whereas it is an almost impossible job for her to initially break through the row of partially severed seams. This is particularly true where forms 12 include a great number of sheets, up to as many as twenty which are sometimes used. Even forms including only as many as eight copies are very difiicult to sever.

Description FIGS. 411

In FIG. 4 is shown an adjustable form 10A of the bursting apparatus of this invention having a cover 100A shown in phantom. The distance between clamps 20A and 21A can be varied by adjustment of the initial position of right-hand clamp 21A as later described in detail to accommodate forms of varying widths. Movement of clamp 21A carries with it base plate 29A and positioning tab 83A to vary their distance from stationary positioning tab 81A, clamp 20A and base plate 28A. The height or length of table 18A can be adjusted for receiving forms 12 of varying lengths by adjustment of movable positioning tabs 82A along slots 89A with which they are engaged. Table 18A is formed by extension of base plates 28A and 29A toward each other include interlocking projections 102A and indentations 104A to provide a substantially continuou surface for table 18A regardless of initial adjustment or bursting movement of clamp 21A.

Adjustment of the initial position of clamp 21A is accomplished through adjusting device 106A shown in FIG. 6 including an adjusting knob 108A connected to adjusting mechanism 106A, which is of the lead-screw and nut type. Mechanism 106A includes a lead screw 110A engaged within nut 112A and supported by hearing 114A. A collar 116A secured to lead screw 110A abuts against one side of bearing 114A. A lateral extension 118A from nut 112A is disposed under slot 52A in the plate 54A of base frame 16A. A pin 50A extends through slot 52A and is secured to the underside of base plate 29A for connecting adjusting mechanism 106A thereto. Spring 76A connects a lower pin 51A with base frame plate 54A to maintain collar 116A on lead screw 110A urged against bearing 114A and thereby maintain clamp 21A urged toward opposite clamp 20A. Movement of clamp 21A to the right by operation of lever 46A and linkage 42A (later described in detail) is permitted by spring 76A and slot 52A as well as by the freedom of movement of collar 116A toward the right of bearing 114A in a manner later described in detail.

Linkage 42A is of the cam and adjustable follower type. It includes a cam 56A rotatably mounted on the lower side of base frame plate 54A. Follower rods 60A and 61A are mounted to reciprocate within slide bearings 120A and disposed adjacent and on opposite sides of cam 56A. Follower rod 60A is joined to the bottom 66A of lever 26A of clamp 20A by a motion-accommodating joint 65A which is advantageously a ball joint. A compression spring 122A transmits the thrust from collar 124A on follower rod 60A to ball joint 65A to absorb overtravel of rod 60A and to maintain firm clamping pressure upon clamp 20A while clamp 21A is moving laterally away from it.

Cam rollers 126A are mounted on the ends of follower rods 69 and 61A for contacting the surface of cam 56A. Follower rod 611A includes an adjustable extension rod 128A which is threaded. Threaded rod MBA is connected to the cam engaging portion 130A of adjustable follower rod 61A by a motion-accommodating ball joint 131A. Threaded rod 128A is engaged within the lower internally theaded end 66A of lower lever leg 49A of clamp 21A. The engaged length between cam 56A and internally threaded lower end 66A of clamp 21A is easily varied by rotation of threaded rod 128A induced by rotation of knob 133A upon its outer end. As shown in FIG. 7, a pair of tension springs 132A react between the lower ends 66A of clamp levers 26A and the bottom of base frame plate 54A to maintain clamps 29A and 21A urged to the disengaged position shown in FIG. 4. Clamping bars 36A differ from clamping bars 35 in that there are no teeth upon their bottom edges. As shown in FIGS. 4, 5, 7 and 9, base bars 134A are disposed upon base plates 28A and 29A adjacent and parallel to clamping bars 36A when they are moved adjacent the base plates. As shown in FIG. 7, clamping bars 36A wedge- side edges 22 and 24 of form 12 between clamping bars 36A and base bars 134A to firmly secure them therebetween when clamping bars 36A are moved adjacent respective base plates. This permits engagement of a form in which there are no perforations 85 to be grasped by teeth.

Clamp 21A may be moved for either its initial adjustment or lateral bursting movemnt through slot 136A in base frame plate 54A. The wedging of side edges 22 and 2d of form 12 between clamping bars 36A and base bars 134A is illustrated in FIG. 7 in which the tails of side edges 22. and 2d are squeezed upwardly at incline angles by the wedging action of clamping bars 36A and 134A.

Adjusting operation of FIGS. 411

To adjust apparatus 10A for reciving forms 12 of a different width, knob 198A is rotated to adjust clamp 21A and its movable base plate 29A at the proper distance from clamp ZtiA. To help guide this adjustment, a series of indicia 138A are inscribed upon the top of base frame plate 54A adjacent the leading edge 140A of a projection 162A from movable base plate 29A. This lateral movement of clamp 21A and movable base plate BA actuated by adjusting mechanism EMA must be coordinated with adjustment of the length of adjustable follower rod 61A. For narrower forms adjustable follower rod 61A must first be moved out of engagement with cam 56A, and for wider forms the outward movement of adjusting mechanism 106A isunimpeded. In either event after clamp 21A is set in the proper position for the new width of form, adjustable follower rod 61A and particularly roller 126A upon its cam engaging end must be adjusted into contact with cam 56A. That is accomplished by setting roller 126A within the valley 142A of cam 56A as shown in FIG. 6. Knob 133A is accordingly rotated to vary the point of connection of threaded portion 123A of adjustable follower rod 61A with the bottom 65A of lower lever leg 46A of clamp 21A. This varies the effecting length of follower rod 61A between cam 56A and clamp 21A.

Bursting operation of FIGS. 4-41 Upon proper initial setting of the position of clamp 21A, a form 12 is set upon table 18A when apparatus 10A is in the condition shown in FIGS. 4-6. Operating lever 46A is then moved in the direction of curved arrow 96A. This causes apparatus 10A to move to the condition shown in FIGS. 7 and 8 in which clamps NA and 21A are rotated to move clamping bars 136A downwardly into engagement with side edges 22 and 24- of form 12 thereby wedging them between clamping bars 36A and base bars 134A to firmly grasp them. This action is actuated as shown in FIG. 8 by rotation of cam 56A in the direction of arrows 144A to move rollers 126A out of cam valley 142A onto an intermediate cam rise 146A. This initial movement of follower rods A and 61A is just sufficient to move clamps 20 and 21A to grasp side edges 22 and 24 of form 12.

Continued rotation of lever 46A in the direction of arrow 96A as shown in FIGS. 9-11, moves follower rod 61A a considerable distance toward the right in the direction of arrow 148A by movemnt of the high portion 150A of cam 56A into engagement with roller 126A of rod 61A. At the same time, roller 126A of follower rod 60A remains upon a dwell portion 152A of cam 56A, and it merely maintains clamp 20A engaged with the side edge 22 of form 12. This engagement is facilitated by compression spring 122A reacting between motion-accommodating ball joint 65A and the lower end 66A of clamping lever 26A of clamp 20A. The movement of clamp 21A and its adjustable table 29A is permitted by resilient connection 74A and its spring 76A which allows lead screw 110A and nut 112A of adjusting mechanism 106A to be carried to the right along with the adjustable base plate 2 3A as indicated by the space between collar 116A on lead screw llllilA and bearing 114A in FIG. 10. Linkage 42A is therefore of the series type similarly to linkage 42. Clamping action is first accomplished and then further movement of the drive means actuated by lever 46A moves clamps 21A and 20A apart by movement of clamp 21A and its base plate 29A permitted by resilient connections 74A and slot 136A in base frame plate 54A.

FIG. 11 shows how form 12 is pulled apart or specifically how the burst seam is pulled a short distance apart to first break spaced connections 92 in the partially severed rows of seams 90. This severs the main portion S6 of the information bearing sheets from stub edges 88 within which carbons 14, shown in FIG. 1A, are edge bound. The remote edge M5 of carbons 14 is pulled a short distance to the right from the opposite side edge 22 of forms 12 by the bursting motion illustrated in FIGS. 9-11 and are thereby slightly withdrawn from insertion between sheets 86. A series of perforations are shown on the form in FIG. 11, but they need not be present on forms burst by this apparatus and are not utilized in the grasping wedging type of action provided by clamping bars 36A and base bars 134A. Also as shown in FIG. 11, arcuate cutouts 154A permit the edges of form 12 to be easily grasped for insertion and removal. Rear guide tabs 82A are adjusted relative to stationary front guide tabs "79A in accordance with the particular length of form 12 to dispose it in the proper position to be clamped. Side uide tabs 81A and 83A operate in conjunction with respective clamps 26A and MA as previously described.
