Application August s, 1940, semi No. :sans

This invention pertains to paper' trimming apparatus, and more particularly to a combined strip feeding and trimming means for use with Writing and imprintingmachines, computing, tabulatingor addressing machines, strip separating apparatus, or form bursting mechanism wherein continuous strips of marginally punched material are progressively advanced past an operation polnt by a pin type feeding device and thereafter the punched margins are removed therefrom.

The marginal perforations of record or data strips are provided for positive feeding and registering purposes. After having performed this function, the marginal holes have'no'further use. By some persons the marginal punchings may be deemed unsightly. In other instances it may be desirable for handling or filing purposes that the imprinted sheets into which the original strip may be divided be of reduced size.

The present unit incorporates directly with a pin type-feeding unit a rotary cutting disc which cooperates with the feeding unit to progressively sever the punched margin inl unison with advancement of the strip by the feeding unit.

The object of the invention is to simplify the construction as well as the means and mode of operation of strip feeding and trimming equipment whereby they may not only be economically manufactured, but will be more eiiicient in use, uniform in operation, automatic in action, having relatively few operating parts and be unlikely to get out of repair.

A further object of the invention is to provide a combined feeding and trimming unit wherein the parts thereof will cooperate with each other to progressively trim a marginally punched strip in unison with its advancement.

A further object oi.' the invention is to provide a unit of compact form capable of being readily installed in existing imprinting or strip treating apparatus, or which may be conveniently incorporated'in such machines at the time of manufacture.

A further object of the invention is to provide a strip 'feeding and trimming unit embodying the advantageous structural features and inherent meritorious characteristics herein mentioned.

With the above primary and otherv incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their 48 Claims. (Cl. 164-61) equivalents, as hereinafter described or illustratedv in the accompanying drawings.

In the accompanying drawing, wherein is illustrated the preferred but not necessarily the only form of embodiment of the invention, Fig. 1 is a perspective view of a strip feeding and trimming assembly including `a pair of relatively spaced feeding and trimming units embodying the present invention. Fig. 2 is a side elevation of the combined strip feeding and trimming unit. Fig. 3 is a side elevation of the assembly illustrated in Fig. 2, to which is added a strip guide for maintaining the marginally punched margin of the strip operated upon in operative engagement with the feeding pins. Fig. 4 is a top plan view of the unit. Fig. 5 is a side elevation from the side opposite that shown in Fig. 3, illustrating the relation of the strip guide or hold-down member. Fig. 6 is a view similar to Fig. 5 showing the strip guide in elevated or retracted position. Fig. 7 is a front elevation of the feeding and trimming unit embodying a strip breaking feature. Fig. 8 is a detail view of a portion of a marginally punched strip upon which the present unit is' operative, showing a portion of the punched margin separated therefrom, as by the present trimmer.

Fig. 9 is a perspective view of the cooperating trimmer disc and pin wheel feeding device combined with a transverse cut-off device. Fig. 10 is a transverse sectional view of the assembly illustrated in Fig. 9. Fig. 11 is a perspective view of a portion of the trimmer and strip feeding assembly illustrating the relation of the, slotted strip guide. Fig. 12 is a perspective view of a portion of the continuous strip operated upon illustrating trimming and severing operations performed thereon.

Like parts are indicated by similar characters of reference throughout the several views.

The present unit may be utilized to sever by cutting action the marginal perforate portion of the stripin the event that the line of division has not been previously weakened, or in the latter event a relatively dull member may be employed for bursting the strip on such weakened line.'

In Fig. l. of the drawings there is illustrated an assembly to be incorporated in a strip treating apparatus, which may be a writing or imprinting machine, a tabulator, or addressing machine, astrip separator for ciisassembling a manifolding packet of record and transfer material, a form bursting machine for dividing continuous strips into individual sheets or other apparatus relative to which a marginally punched strip is advanced.

The particular purpose or function of the machine is immaterial. This assembly comprises a rotary main shaft |8 having thereon a pair of relatively spaced axially adjustable pin wheels 8. Carried thereby are radially spaced feeding pins 9 progressively engageable in longitudinally spaced holes I in the strip or strips .Il of record material to be advanced and simultaneously trimmed. The pin wheels 8 are keyed to the shaft I8 for unison rotation by a key having engagement in the spline 21. y

The particular pin wheel feeding .device illustrated is that disclosed and claimed in Reissue Patent No. 20,888, the particular construction of which forms no part, per se, of the present invention. Other forms of pin type feeding devices may be employed in lieu thereof without departing from the spirit or scope of the present invention.

Intermediate the pin wheels 8 is a plurality of axially adjustable strip supporting discs 28, also splined upon the shaft I8, which medially support the strip during its advancement by the pin wheels.

Each pin Wheel 8 is provided with a smooth, hard cylindrical surface 29 at the inner sides of the plurality of feeding pins 9. Engaging each of the smooth cylindrical faces 29 Vof the pin wheels 8 is a rotary disc cutter 23. Each cutter 23 is carried by an arm 24 loosely pivoted for vertical oscillation upon a shaft 25 extending in parallel spaced relation with the pin wheel shaft I8. The pivotally mounted endl of the arm 24 is positioned between the furcations of a slotted bracket 38 axially adjustable upon the shaft 25 and ilxedly secured in adjusted position thereon by a set screw 30' engaging the shaft 25. Each bracket 30 includes a projecting head 3| through which extends a screw threaded rod 32 pivoted at 33 to the rock arm 24. I'he rod 32 is surrounded by a helical spring 35 against which the rock arm 24 is yieldingly retractable. Screw threaded upon the upper end of the thrust rod 32 is a knurled nut or stop head 3G which abuts upon an adjustable sleeve 31 screw threaded into the head 3| of the bracket 30 to adjustably restrict the movement of the rock arm 24 in downwardly direction. The upward movement of the arm is yieldingly resisted by the spring 35.

By adjustment of the nut 36 the cutting pressure of the rotary disc 23 against the portion of the strip passing over the face 29 of the pin wheel may be regulated.

In the particular type of pin wheel illustrated, A,

but which is not essential to the present purpose, the pins 9 are automatically progressively extensible and retractible as the pin wheel is rotated. Means is provided by which the arc within which the pins are extended may be varied circumfercntially of the pin wheel by rotative adjustment of a notched disc 4| operatively connected with the pin control mechanism within the pin wheel. Adjacent the notched adjusting disc 4| is a disc 42 to winch is pivoted at 43 a spring pressed pawl 44 engageable in one or another of several peripheral notches 45 in the disc 4|. By disengaging the pawl 44, the adjusting disc 4| may be rotated to circumferentially change the position of operation of the pins 9 and cause them to project at any desired portion of the periphery of the pin wheel d. To maintain the respective discs 4| and 42 stationary when interlocked, the latter is provided with a bifurcated arm 41 engaging with a rod 55 extending in parallel spaced relation with the wheel shaft 8. To facilitate the rotary adjustment of the disc 4| when the locking pawl 44 has been disengaged, a portion of the periphery of the disc is serrated at 49, and may be secured in its adjusted position by a clamp bolt 58 extending through an arcuate slot 5| in the disc. It is to be understood, however, that the adjustable feeding pins and control therefor form no part, per se, of thepresent invention. A pin wheel or other form of travel- 'ing pin carrier having relatively iixed pins will operate equally as well.

Upon rotation of the shaft I8, the feeding pins 9, having engagement in the holes lll of the strip, advance the strip, while the rotary cutter 23 pressing upon the strip against the smooth hardened surface 29 of the pin wheel severs the str-ip longitudinally adjacent the inner sides of the longitudinally spaced feed holes in unison with the advancement of the strip.

To hold the advancing strip in feeding engagement with the feeding pins 9 during the feeding and trimming operations, there is provided a slotted arcuate paper guide 53 into the slot 54 0f which the pins 9 project through the holes I0 of the strip. Each paper guide 53 is rotatively engaged at one end about the rod 55. At its free end it carries an upstanding ear 51. The ear 51 is pivotally connected to the free end of a rock arm 58 secured to a hub 62 mounted for rotative adjustment upon a bushing or sleeve 59, which 'in turn is axially adjustable on the rod 55. The

bushing sleeve 59 and with it the slotted paper guide 53 are secured in selected positions of axial adjustment relative to the rod 55 by a set screw 50. The set screw 68 transxes a collar 55 on the bushing sleeve 59 beside the arm hub 62. The arm 58 and with it the slotted paper guide 53 are rotatively adjustable upon the bushing sleeve 59 and may be secured in adjusted position relative thereto by a set screw 5|. The slotted guide may be raised as shown in Fig. 6, to facilitate engagement of the marginally punched paper with the feeding pins 9, after which it is restored to its paper hold-down position as shown in Fig. 5. A stop lug 63 on the arm 58 engages with one edge of the bifurcated arm 41 to limit the approach of the arcuate paper guide 53 toward the pin wheel.

As the paper strip is advanced beneath the slotted paper guide 53, the cutter disc 23 engages therewith under spring pressure of the spring 35 within the limit determined by the adjustment of the interengaging nut 36 and sleeve 31 upon the thrust rod 32 which is otherwise free to yield against the pressure spring 35. It is the rotation of the pin wheel which effects rotation of the cutter 23 and which affords an abutment face 29 against which the cutter disc 23 exerts its strip severing pressure. Likewise, it is the pin wheel feed device which advances themarginally punched strip to the cutter 23 and regulates the cutting operation which is thus synchronized with the strip advancement. i

In Fig. 7 there is shown a front view of the strip feeding and trimming unit wherein the pin wheel is provided with a peripheral groove 54 with which the rotary severing disc 23 registers and into which the spring 35 tends to project its periphery. The pressure exerted by the rotary severing disc 23 upon a pre-weakened division line I2 of the strip serves to break the strip along such line s and thus sever the perforated margin from the strip. .In such event the edge of the dise need not be sharp nor exert any cutting action. but will break the strip on the preformed weakened division line by pressure. In Figs. 9 to 11 there is illustrated a compact unitary assembly of the strip feeding and trimming devices with a strip severing device. The roller II, in addition to its coaction with the companion roller 61 in breaking or pin wheels. The rollers 66 and 61 are interconnected for unison rotation by intermeshing gears 68. The upper roller 66 carries a blade 69 which vcoacts with an insert 10 of rubber, ber. or similar material in the lower roller 66. The blade 69 may be either a sharp cutter blade or it may be a blunt blade, adapted to break the strip on a previously scored or weakened division line. The

blade 69 and insert strip 1,0 do not necessarily f extend the full length of the roller or the width of the strip Il, but may lterminate coincident with or nightly inwarmyvof the path of the trimmer discs 23. If the blade extends to or slightly beyond the plane of enggement of the trimmer discs23 with the pin wheels 8, the transverse cut or break effected by the blade 89 will be subsequently intersected by the longitudinal lines of severances eiected by the trimmer discs 23, resulting in complete separation of the forms, checks, or sheets. It is preferred, however, that the blade 69 and insert strip 'I0 shall terminate in slightly inwardly spaced relation with lines of severance of the trimmer discs 23, whereby short unbroken or uncut portions will remain after the punched. margins have been removed, thus leaving the trimmed checks or forms interconnected in series'but capable of being easily separated manually as may be required. Slotted strip guides 53a cooperate with the 'pin wheels 8 to direct the strip relative to the trimming discs 23.

The subject matter of the present application is broadly disclosed, but not particularly claimed, in copending application Serial No. 279,341, now Patent No. 2,252,734 issued August 19, 1941, which is a division of an earlier application Serial No. 116,552, filed December 18, 1936, now matured into LettersPatent No. 2,172,414, of which the present application is a continuation in part, and in copending application Serial- No. 294,199, now Patent No. 2,252,735 issued August 19, 1941, which is a division of an earlier application Serial No. 115,804, filed December 14, 1936, and now matured into Letters Patent No. 2,177,675, and in copending application Serial No. 277,484, now Patent No. 2,327,377 issued August 24, 1943, which is a continuation in part of an earlier application Serial No. 157,706, led August 6, 1937, now matured into Letters Patent No. 2,160,916.
