deceased Original application December 18, 1936, Serial No. 116,552. Divided and this application June 15, 1939, Serial No. 279,341 a This invention comprises a strip feeding and imprinting apparatus wherein successive impressions are made at uniformly spaced intervals upon a traveling strip of material simultaneously with its advancement and the imprinted strip delivered in folded condition to a storage compartment or severed into a successionof independent sheets or forms as may be desired.

This application is a division of application Serial No. 116,552, filed December 18, 1936, now matured into Patent No. 2,172,414.

For illustrative purposes, but with no intent to unduly limit the application or scope of the invention, it has-been illustrated as applied to a rotary apparatus for imprinting upon checks, vouchers or the like, facsimile signatures and macerating the amount line area of the check to prevent changing the hiscribed amount. It is to be understood, however, that other printing plates, cutting or punching dies-or other strip treatment devices may be substituted for the printing and marking plates of the present apparatus, and that the pin type feeding means herein described may be employed for feeding strips of various materials and of different widths past operating position for other than imprinting purposes.

In the present application of the invention, a continuous succession of series connected impression receiving forms, checks, vouchers, form letters, or the like, are advanced in properly timed sequence past the imprinting member by a pin type feeding device which may be embodied in the platen element of the imprinting apparatus or may be offset relative thereto. The feeding pins progressively engage in marginally punched holes in the strip of impression receiving material.

The rotary imprinting member being intermittently engageable with the material transmits thereto successive frictional feeding impulses simultaneously with its advancement by the pin type feeding means, which continues such advancement intermediate succeeding impressions. The material is thus continuously advanced at a uniform rate of speed.

The provision of marginally punched feed holes and the pin type feeding device engageable lated condition but still interconnected one to 31 claims. (or. 164-61) advancement of the series connected form stationery past the imprinting position, sometimes they may be undesirable and unnecessary after the completion of the imprinting operation.

' another. In lieu of slitting or cutting thestrip to remove the punched marginal areas, the strip of forms may be scored or perforated on longitudinal lines during the initial printing operation to provide longitudinal weakened division lines.

The strip may also be transversely scored or perforated to afiord weakened division lines between succeeding forms. The strip may be broken on longitudinal scored or perforated lines by breaker devices instead of cutters for remov ing the punched margins. The imprinted strip from which the punched margins have been removed my be delivered to a receiving compartment with the imprinted forms interconnected in. continuous succession. In lieu thereof the stationerystrip may be acted upon by cutters or breaking devices which transversely divide the strip into a succession of separate portions or sheets. In such case the separated'checks or forms fall upon a slowly traveling apron from which they are automatically transferred in more closely assembled relation to a receiving tray removable from .the machine.

The object of the invention is to provide an apparatus for imprinting or otherwise, operating upon a continuous strip of material and having pin type feeding means for progressively advancing material in continuous movement past an opera-ting position, which may be economically therein enables corresponding predeterminedareas of each succeeding form or check to be presented in exact registry with the'imprinting de manufactured and which will be simple in construction, efilcient in use, of compact form, having relatively few operating parts, and unlikely to get out of repair.

A further important feature of the invention is-the retention of marginally punched areas upon the stationery material so long as they are useful and desirable for feeding and registry purposes,

and provision of means for their automatic elimination when no longer needed and when undesirable, since they give to the forms an unconventional appearance. 7

A further and highly important object of the invention is to maintain a definite travel relation of the material being advanced to the operating engagement of the imprinting or other apparatus,

whereby predetermined areas of succeeding checks, forms or other portions of the strip of material may be accurately registered -i11 the operation receiving position.

A further object of the invention is to insure uniform travel of the material in relation with the operation of the apparatus.

A further object of the invention is to incorporate in such imprinting apparatus means for automatically removing the punched marginal areas from the stationery strip and subsequently transversely dividing the strip into succeeding forms.

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.

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

The apparatus, shown for illustrative purposes in Fig. 1, includes a main frame I having therein supply and receiving compartments 2 and 3 from sheaves which the material operated upon is withdrawn at one side of the apparatus and returned thereto the main frame l, and over the other of which the material is returned to the receiving compartment 3 after having passed between the platen and imprinting rollers 5 and 6. The several rollers, including the platen and imprinting rollers and inking rollers 75, are interconnected for unison rotation by a train of intermeshing gear members ii and are driven from a power shaft holes in opposite margins of the strip are shown,

one such group of feeding pins may be omitted and advancement of the strip effected by pins engaging holes M in one margin only thereof.

The feeding pins l3 may be fixedly mounted in the platen roll or carried by a separate feed roll adjacent thereto and project radially beyond the periphery of the platen or the feed roll, as the case may be, throughout the entire periphery thereof. However, these pins are preferably, though not necessarily, mounted for recipro-= 'catory movement in radial directions whereby they are progressively projected beyond the periphery of the carrying unit or roll as they approach the path of travel'of the marginally punched material with which they engage to ad vance the material a limited distance, and then are automatically withdrawn progressively from engagement therewith to positions wholly within. the periphery of the rotary carrying member, in unison with the rotation of the pin carrying unit or roll.

Such construction, per se, formsno part of the present invention, but is fully set forth and claimed in United States Letters Patent to Sherman, Nos. 2,000,649, 2,000,650 and 2,000,651, dated May 7, 1935.

The imprinting roll 5 is shown in the drawings as provided with a printing plate 59 by which a facsimile signature may be imprinted upon succeeding checks or vouchers comprising the traveling strip I5. The roll is also shown provided with an embossing plate 28 coacting with a corresponding plate 21 carried by the platen roll 5 to indent or macerate the traveling checks; or vouchers upon the area carrying the written amount for which the check or voucher is drawn to prevent fraudulent change of such amount.

The imprinting roll 6 is illustrated as provided with longitudinal and circumferential intersecting undercut grooves 22 in which other imprinting or embossing plates may be mounted by means of suitable clamp members 23 engaged within the undercut grooves 22. Y

The engagement of the imprinting roller t with the strip imparts thereto a frictional feeding impulse supplemental to the feeding movement transmitted by the pin feeding parts, which continues uninterruptedly the advancement of the strip intermediate succeedng printing impressions at a uniform speed.

While in Fig. 3 and also Fig. 6 the platen roll is shown equipped with feeding pin H, as an alternative' construction there is shown in Fig. 4 a smooth platen roll 5 and adjacent thereto a separate strip feeding roll 24 carrying the feeding pins l3 engageable in the marginal perforations M of the strip as before described. This feeding roll 24 maybe of any suitable type.

In order that material of different widths may be imprinted by the same apparatus, the pin type feeding units are preferably mounted for axial adjustment one relative to the other. One of the pin wheel units may be incorporated in the platen roll and the other unit mounted for adjustment relative thereto as illustrated in Fig. 6. .In lieu thereof'the pin type feeding device 24, offset relative to the platen roll as shown in Fig. 4, may comprise an adjustable skeleton type of construction as illustrated in Fig. 7, wherein the skeleton frame and spacer discs intermediate pin wheels eifectively support 'the material while passing in engagement with the feeding roller. The particular construction of the adjustable pin type feeding device here shown for illustrative purpose forms no part of the present invention per se, but comprises the subject matter of a copending application Serial No. 116,553, which resulted in Patent No. 2,095,293, and to which cross reference is made. As shown in Fig. 9, the feeding pins it are mounted in the carrying head for reciprocatory motion in radial directions as minal head 26 and the supporting discs 3| rotate relative thereto. To eifect such rotation, the pin wheel unit is provided with a hub 33 secured to the shaft 28 by a set screw 34. Thus the pin wheel units, together with the assembly of rods 21 and discs 3|, rotate as a single unit, carrying therewith the pins l3 of the respective heads 25 and 30, which are caused to travel about their corresponding control cams l9, which are held stationarily by the sleeve 29 and arm 32. i

In Fig. 6 there is shown a further modification wherein the features of the pin carrying platen roll 5 and those of the skeleton feed roll are combined in a single unit. In this construction a portion of the roll comprises a platen 5a having at one end thereof the pin carrying head 25a. Projecting from the opposite end of the platen section 5a is the seriesof circumferentially spaced mounting rods 21 carrying at their extremities the mounting head 26. Slidingly adjustable upon the rods 2'! intermediat the terplatensection 5a is a pin wheel unit 30 axially adjustable toward and from the platen roll section 5a to accommodate marginally punchedmaterial of different widths. Intermediate the pinwheel unit 39 and the platen roll section 5a is a supporting disc 3|, also axially adjustable as before described for supporting the portion of the strip of material beyond the end of the platen roll.

a While disappearing pins, as heretofore described, are quite desirable for certain conditions ,of use, they are not, however, essential for operthey travel about an eccentric cam IS, the marginal flange iii of which is engaged in notches H in the inner ends of the pins.

The skeleton or cage-like construction shown in Fig. 7 comprises spaced relatively fixed heads 25 and 26, .interconnected with each other at circumferentially spaced intervals by a circular series of longitudinal rods 21. skeleton structure is mounted and driving shaft 28.

This cage-like upon a supporting" In the drawings the head 25 is shown provided with reciprocatory disappearing feed pins l3.

Mounted upon the circumferentially spaced longitudinal rods 21 and axially adjustable thereon and upon a concentric sleeve 29 surrounding the shaft 28 is a second pin wheel unit 30 also carry ing a group of reciprocatory disappearing feed pins l3. The feeding units 25 and 30 are relatively adjustable in an axial direction by movement of the lattertoward and from the former upon the supporting rods 21 and sleeve 29 into agreement with the marginal feeding holes ll of the material strip to be fed. Located intermediate the pin wheel units 25 and 39 are discs 3| also axially adjustable to and fro upon' the rods 21 and sleeve 29 in spaced relation with each other and with the pin type feeding units 25 and 30. These discs 3| serve to support the marginally punched material being fed intermediate the points of engagement with the feeding units.

The'control earns 16 within the pin type units 25 and 30 are secured to the sleeve 29, which in turn is provided with a bifurcated arm 32 by which the concentric sleeve 29 and pin control cams 16 carried thereby are held stationarily while the group of mounting rods 21 and the pin carrying heads 25 and 30 and the intermediate ation of the present apparatus, and the radial feeding pins i3 may be fixedly mounted in their respective carrying heads.

In Fig. 8 are shown two relatively spaced ronot only highly desirable, but are necessary to afford positive feeding action and maintain accurate registry.

When the succeeding forms have been presented to the imprinting devices in exact registry, by the coaction of the pin type feeding devices in the marginally punched holes of the strip, the marginally punched holes will have performed their only useful mechanical purpose and there no longer remains any functional reason for their retention. For aesthetic reasons, objections are sometimes raised to their unconventional appearance. Therefore, means are provided by which such marginally punched areas are automatically removed as the imprinted forms are discharged from the machine.

Referring particularly to Fig. 10, wherein is shown a further development of the apparatus illustrated in Fig. 1, there is located beyond the rows of marginally punched feed holes l4' and cut therefrom continuous marginal portions 52 as shown in Fig. 12. These punched marginal areas removed from the strip of series connected forms are waste material. The imprinted forms in their continued advancement beyond the slitter roll pass in engaging relation with a cut-off device by which the stationery strip is transversely severed .into succeeding separate forms, checks or sheets 53. The cut-E device may be of any suitable form, but for illustrative purposes has been shown in Fig. 10 as comprising a pair of coacting rolls i l- 15, one of which is provided with spaced strip engaging blades d6 cooperating with pressure pads i? upon-the other roll to transversely divide the strip atpredetermined spaced intervals. The feeding and imprinting devices l3 and E and the trimmer discs ll and severing rolls ML-d5 are actuated in synchronisin from the drive shaft 82 by a gear train interconnecting the several operative parts and indicated by dotted lines in Fig. 10. Since the advancement of the strip past such cutting de- As before mentioned, the stationery strip may be initially scored or perforated on both longitudinal and transverse lines upon which it is to be subsequently severed by the slitter roll discs ll and severing devices t l-d5, respectively, in which case these devices will merely break the strip onv such weakened lines. However, since the progressive advancement of the strip is accurately controlled and registry automatically maintained, the strip may be severed both longitudinally and'transversely by the rolls at; at and t5 without preliminary scoring or weakening,

The forms or checks after being severed from the supply strip fall upon a slowly traveling apron which comprises an endlem belt S's" passing about rollers or pulleys Ill. One of the apron pulleys is connected with a ratchet wheel 2, with which cooperates a pawl 59 carried by an oscillatory armbll. The arm is actuated from any suitable moving part of the apparatus. In the present instance it is shown connected bya link 5i with a disc 52 connected to and rotating with oneof the cut-ofi rolls B5. The link, arm and pawl combination transmits to the traveling apron db an intermittent advance movement, by. which the severed imprinted forms deposited thereon are slowly advanced. g

' As the deposited forms reach the end of the traveling apron they fall therefrom onto a tray 53 removably supported upon a traveling conveyor 5 3. This conveyor is actuated from the traveling apron, but at a lesser rate of speed,

by a chain drive 56' operating over a pair of sprockets 55, one of which is connected for unison rotation with the ratchet wheel 48 and apron pulley 47, and the other of which is operatively connected with a corresponding sprocket which drives the chain 56 having engagement with a larger sprocket 5'5 connected to and driving the conveyor 53.

Due to the differential speed of the apron '46 and conveyor 54, the forms are more closely deposited on the tray 53 than on the apron 4B and are stacked in closely overlapping relation on such conveyor tray.

The apparatus being designed for high speed acsavec operation, the traveling apron and conveyor arrangement facilitates delivery of the severed forms.

In Figs. 13 to 15 there is shown a more compact arrangement of the feeding, trimming and cutting devices, wherein the roller :35, in addition to its coaction with the roller dd in breaking or cutting the strip transversely, carries the feeding pins 713 engageable in the marginally punched holes of the strip and also provides an abutment for the trimming discs M which sever the punched margins of the strip as it is fed between the rolls.

'I'he rollers it and 35 are interconnected for unison rotation by intermeshing gears 5?. The upper roller d lcarries a blade 53 which coacts with an insert 59 of rubber, fiber or similar material in the lower roller A5. The blade 58 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 58 and insert strip 59 do not extend the full length of the rolls nor the width of the strips, but terminate either coincident with or slightly inwardly of the path of the trimmer discs 53' upon the roll. If the blade extends to or slightly beyond the path of travel of the trimmer discs upon the roll, the transverse cut or break imposed by the blade 58 will be subsequently intersected by the longitudinal cuts effected by the trimmer discs ll 5 resulting in complete separation of the forms, checks or sheets as is shown in Fig. 12. It is preferred, however, that the blade 58 and insert strip 5Q shall terminate in slightly inwardly spaced relation with the path of travel of the trimmer discs All K whereby a short unbroken or uncut portion will remain'after the punched marginshave been removed, thus leaving the trimmed checks or forms interconnected in series but capable of being easily separated manually as may be required.

At the moment of severance the advanced portion of the strip is grasped betweenthe pads d? or 59 of the rolls'tbl. and it, in bridging relation across the grooved recess in the roll 35. It is held thereby against retractive movement or develop ment of slack, and is engaged under pressure by the blade carried by the'roll t l. The blade ll or 59, which projects beyond the periphery of the roll t l, tends to deflect or depress the portion of the strip contiguous to the transverse weakened j division line, into the grooved depression of the roll 45. Such deflection of the strip being resisted by the grasp of the rolls thereon, the strip is tensionecl by the pressure of the blade in excess of the tensile strength of the transverse weakened division line, causing a bursting'or severance of the strip along such line. In the event that the blade is sharp and the operation is that of cutting or shearing the strip, the operation and eifect are similar. That is, the tensioning of the strip across the grooved depression afiords the necessary resistance against which the-cutting action of the blade may be efiected. Otherwise, whether the blade be sharp or dull, the strip might yield into the recess under pressure of the blade and into conformity therewith, without being severed thereby.

The rollers 44 and 45 exert a certain amount of pull upon the strip to advance the terminal por-' tion thereof in unison with its advancement by the pin type feeding device and thus maintains the strip at all times taut and prevents accumulation of slack. v

The intermittent engagement of the radial blade with the strip momentarily increases the tension 01' the strip beyond its normal degree and in excess of its tensile resistance, thus effecting severance at predetermined longitudinally spaced intervals. Cross reference is made to copending applications Serial No. 295,814, filed September 20, 1939; Serial No. 294,986, filed January 9, 1939; Serial No. 226, 60, flied August 25, 1938; Serial No. 251,185, filed January ,16, 1939; and Serial No. 294,199, which is a division of application Serial No. 115,804, filed December 14, 1936, now matured into Letters Patent No. 2,177,675; also pending application Serial No. 350,545, filed August 3, 1940.
