Diesba ch, Hamilton, Ohio, trustees Application January 18, 1954, Serial No. 404,547 a Claims. 01. 271-24 of perforations. These apertures cooperate with feeding and aligning "mechanism of the register to insure that I the superimposed forms of each set are delivered onto the writing platen of the machine in accurate registry with respect to one another.

In my copending patent application Serial No. 404,561, filed January 18, 1954, I have disclosed improved feeding and aligning mechanism for an autographic register which incorporates a pair of feed discs and a grip roller. The manifolding stationery is engaged between the grip roller, which contacts the upper surface thereof,and the The roller and discs are driven by means such as a hand crank and serve to advancethe stationery. They also cooperate to align in a general way the superimposed forms by virtue of their relationship to the apertures in the forms.

In addition, extensible p ns carried on the feed disci serve to complete the alignment of the forms, the aligning pins becoming effective during the last portion onlyof the operating cycle of the machine, at whichtime they engage in the apertures and move the forms into accurate registrywith respect toone another. is cammed upwardly out of contact with the form'sfduring this period in order to free moved by the pins. Except for this one, brief period in the cycle of operation, the grip roller is in contact with the forms, being urged downwardly by springs. Thus, in

right of the writing platen as order to load the register by placing the stationery forms initially in position to be advanced and aligned, means must be provided to raise the grip roller'so that the apertures in the first set of forms of theStationery' can he engaged over the aligning pins. It is this particular phase of the operation of an autographic register to which the present invention is directed, and it is the objective of the invention to provide an improved grip roller con struction which is simple to operate and which is efficient in operation.

One of the novel features of the invention is the pro- .vision of a grip roller assembly for an autographic register in which springs are employed to urge the roller downwardly into operating position and are also utilized to urge the roller upwardly for loading purposes. -.In their hold-down function the springs are employed int r sion to pull the roller downwardly intoposition to co.- operate with the feed discs. To raise and free the grip roller for loading purposes, the same springsvare utilized in compression to push the roller {outof conventional and is known to indicated at 13.

\ l sten d oct. 15, 1957 "ice a 2 tact with the feed discs. In order to change over the springs from one operating condition to the other, a novel shifting mechanism is provided. In the preferred embodiment the shift is accomplished by the simple expedient of raisingor lowering a finger operated latch which is so placed so as to be instantly accessible to the opera-- tor upon the opening of the register casing. For a complete disclosure of a grip roller assembly embodying the principles of the present invention, reference is made to the following detailed description of the drawings in which: Figure 1 is a top plan view of an autographic register incorporating an improved grip roller construction of the present invention. Figure 2 is a view similar to Figure 1 in which the lid ofthe register isopen, a portion only of the lid being shown. d

Figure 4 is across sectional view taken on the line 4-4 of Figure3. Figure 5 is a. cross sectional view vtaken on the line 5-5 of Figure 3, showing the grip roller in operating position. d Figure 6 is a view similar to Figure 5 showing the grip roller in the process of being raised. J d Figure 7 is across-sectional view taken onthe line 7--7 of Figure 3 showing the side of theregister opposite to the. one illustrated in Figures 5 and 6, in which the grip roller is in the position shown in Figure 6. Figure 8 is a view similar to Figures 5 and 6 showing the grip roller in raised or released position. 1 i Figure 9. is a view' similar to Figure 7 showing the grip roller in released position. v .ln the drawings an autographic register is indicated generally by the numeral 10. The register shown has a cover or lid 11 whichis formed inone piece as acasting of light metal such as aluminum. Thelid preferably is hinged to the register casing at one side thereof as shown in Figure 2. The lid has a rectangular window 12 in the top thereof to expose manifolding forms such as the one The forms are brought into registry upon a writing platen 14, being fed from a packet (not shown) which is placed within the register casing beneath the writing platen. The forms are threaded through an improved separator assembly shown at the it appears in Figure 2. The separator assembly is indicated generally by the numeral 15 and is disclosed in detail in my copending patentap plication Serial No. 404,707, filed January, 18, 1954.; L The manifolding forms are withdrawn from the packet, through strip separators, across'the writing platen, where they are interleaved with carbon paper, and delivered in registry with respect to one another on the writing platen bythe feeding and aligningmechanism of copending ap plication Serial No. 404,561, referred to above. During the advancing operation, aset of forms is also discharged through a delivery slot 16 onto the .top of the cover at the left as it appears in Figure 1 where they may be torn from the strip. f At the same time, the lowermost one of. the forms is delivered into a storage compartment. indicated generally at 17 and which is located-beneath the coveror lid at the left side of the machine as it appears in FigureZ I H The above described path of movement of the forms is those skilled in the art. For.

0 this reason the parts of theregister which concern the storage of the forms and their movement to and fromthefeeding and aligning mechanism, which is located near the center of theregisterat the .head end f the Writing asant-estates s wai J shown in "Figure 3, i. e.,

The feeding and aligning mechanism is mounted in a chassis consisting of a pair of side plates 18-18. These plates are secured to the bottom of the register casing adjacent to the respective ppposite side' wallsithereofi Each wall includesa foot ilange 19 which maybe spot welded-to the bottom of the register-casi gand .an' inturned, vertical flange 20 which serves to rig ify the up right portion of the wall. The feeding and aligning mech: anism consists generally of agrip roller 21,.a pair of feed discs 22-22, a pair of aligning pin actuatorcams 23-23 andapairof lift-cams 24 -24 which are designed to momentarily raise the :grip roller durinjg that portion .of thecycle of operationof thema'chine when twoaligning pinsindicated at 25-25 engagewithin the feedapertures provided inthe forms. i

The two feeddiscs are mounted upon a shaft 26 which is journalled at its opposite ends in the side walls 18-18 of the chassisand whichzextendsacrossthe register parallel with and belowtheigri'p roller. 'Oneend of the shaft 26 extends through a wall 18 at the right side of the autographic register (theleftside as seen. in Figure 3) and has a gear'27 pinned at its outer end. Gear 27 is designed to'mesh with a'gear 28 which is pinned to. the end of a shaft 29 which is part of the grip roller assembly. Thus, the feed discs and grip. roller are arranged to rotate together. Shaft 26hasa gear 30 at the rightendtthereof just inwardly of the chassis wall which meshes with. agear 31 pinned to across shaft 32 which mounts the two actuator cams '23-'23. 'A'third shaft 33 is journalledin the chassis walls. This shaft has a gear 34 pinned toit which is meshed with-gear 316 The shaft 33 extends outwardly through the wall '18 at the left sideof the machinevand has a hand crank 35 pinned to itsouter end. Thus, rotation of shaft 33 by means of the hand crank drives both shaft 32 and the shaft 26 through the gear train consisting of gears 34, 31 and 30. The ratio betweengear 34 on the crank shaft 33 fifld the gear 31 (ill Shaft 3Z-Which mounts theactuator cams 23, is one to one. By contrast, the' gear ratiobetween gear 31 on the actuator shaft 32 and the ear 30 on shaf' 26, is one to two. Thus, shaft 26 makes two revolutions for each revolution of shaft 32.

As: disclosed in detail in my copending ap lication Serial No. 404,561, the aligning pins 25 are slidably mounted upon the feed discs 22'. The respective pins are formed as integral parts of elliptically shaped plat s 36-36,.eachof whichis arranged to slidedianietrically of the feed-disc upon which it is mounted between a retractedpo ition in which the aligning inis inwardly of the periphery of the feed disc and an extended position in which the pinis outwardly. of thefeed disc. Normally each plate 36 is urged toward the retracted position by means" of a hairpin spring (not shown in the present instance). The actuator camsizs are designed to contact andextenclthe aligning pin plates. Such cofi't'a'ct, however, takes place only in the position of thecams123,

' when they are substantially straight upyand down and the pins are adjacent to the feed roller" 21. Due to the one to two. ratio of the respective gears 31 and 30, this occurs only once in every two revolutions of the shaft 26. The purposeof this arrangement is to adapt thefeeding and aligning mechanism to forms of various sizes, and particularly long forms.

The grip roller lift cams 24-24 are also mounted uponthe shaft 26. These cams are designed to engage the-grip roller at thesame time that the aligning ins move into the apertures in the forms so as to lift the roller and thereby free the forms so that they may be moved by the pins for registry purposes Each of the two, grip rollerv lifting cams is pinned to a gear 37 which is in mesh with and is driven'by a gear 38. ,The ratio between gears37 and 38 is'one' to one. Gear 38..is pinned to the shaft 32*which makes only one revolution foreac'lt two'of the shaft 26. Thus, there can-'bieno positive conmotion between the gear 37 and the groprollerlift cant as, the shaft 26 merely journalling the twoclements.

In h QPe Qn 9 h n sand al gn m ho nisrn, the grip roller 21 is constantly urged downwardly under the action of two coil springs, one of which, at the right side of the register, is indicated at 39 and the other of which, at the left side of the register, is indicated at 40. Thus, during the operation of the register the only time that the grip roller 21 is lifted is when it is engaged by the cams 24-24, and this occurs at a time just prior to the time of the completion of acycleof operation. At the end of the cycle the grip roller is again urged downwardly by the two springs 39 and 40 so as to hold the forms securely on the writing platen when they are being written upon.

The grip roller 21 is configurated to provide two tread portions 41-41 which are defined by pairs of grooves. The tread portions are spaced to contact the peripheries of the respective feed discs 22-22. In addition, the grip roller at the respective outer endsthercof journals two sleeves 42-42. These sleeves rotate freely'on the roller and arein position to be engagedby the -respective lift cams 24-24. The sleeves are provided because the roller in operation revolves at a considerably higher rate of speedrthan thelift cams and in the opposite direction. They, therefore, ser ve-to protect the lobes on the twolift cams 24against wear. U

The oppositeends .of the grip roller are journalled in pivotallymounted bearing arms 43-43. Each arrnmay include a..seat for an antifriction,bearing (not shown) atone end thereof to journal the shaft 29 of the grip rollerassembly. Theother end of each arm has a plain bore throughit toreceive a bolt- 44 by means of which the arm is pivotally journalled to the adjacent side plate 18 of the chassis. The respective coil springs 39 and .40 arepinnedto the respective grip roller bearing arms un dei'n'eath theroller journals as at 45-45 and extend downalong the outer-faces of the chassis sidewalls. The lower ends or the two springs 39 and 40 are journalled on pins sucha's those indicated at 46-46 inFigure 3. These two latter pins are secured. to rotatably mounted members. These. members respectively-are pinned to the opposite ends of a cross shaftv 4'7 which is journalled in the twoside plates [18-18 and which extends across the machine underneath theshafts of the feeding. and aligning' mechanism. The member to which the lower end of. the spring 39 at the crank or left sideof the register consists .of a simple crank plate48. At the other side or tight, s'ideofthe inachifie the lower .end of spring 40 is inned t a gear4 9. Ihege r' 49 and the crank plate 48, being joined together by the shaft 47, are designed to turn togetherthrough substantially more than ,18'0 .fiOm a position in whic'lithe respective pins .46 areovercenter at a loweredposition to a position in which the pins are overc'ent'er at an upper position. In the lower overcenter position, the two sprihgs 39 and 40 are under considerable tension so that the two bearing arms and-thegrip roller are urged doivnwardlytdbriiig the two'treadportions 41-41 into rolling contact with theperipheries. of the feed discs 22-2 .In the upper o erccnter position,

posed side edge of howeventhe two ins 46-46cdrripress the springs, pushing them upwardly so that they lift the respective bearing arms to elevate the grip roller substantiallyabove the feed discsffor loading purposes. ,The, twospring's 39 and 40, therefore, act nder tensio downwardly and act in com ression to push the grip roller upwardly. The means to shift the springs; from one operating condition to the other consists of a filigeroper'ated actuator -bart50 having a finger tab 51 turned overat the upper end thereof. The actuator bar islslidably mounted at the. rig'htts'ide of the machine in aitainer late 52 whichtna be sp t welded to the outside of the wall ofthe chassis which is at the right. Th plate 52 has an offset 53 on it which defines with the outside of the chassis .wall channel in ii theactuato barjn-a'y slide. The ex-j the actuator bar is conti orated to pro videa gear rack 54. This rack is meshed with an idler gear 55 which serves to maintain the actuator bar in its channel and which is meshed with the gear 49. Thus, moving the actuator bar 50 longitudinally of the channel in which it is seated causes gear 49 to rotate.

It will be seen that the gear rack 54, gear 55, and gear 49 are so interrelated that moving the actuator bar into the lowered position shown in Figure rotates the gear 49 to a position in which the pin 46,-which it carries,is overcenter of a substantially vertical line connecting the center of shaft 47 with the center of pin 45, the latter pin being the one which connectsthe upper end of the spring to the bearing arm. In this position the spring 40 is under considerable tension. The pin 46 is held in this position by the overturned finger tab 51. It will be seen that the upper end of the actuator bar 50 extends through a groove 56 cut in the inner face of the bearing armand that the finger tab 51 extends over the upper surfaceo-f the bearing arm. The tension of the spring tends to pull the actuator bar 50 downwardly, this movement being resisted by the engagement of the finger tab 51 with the upper surface of the bearing arm. With the finger tab thus engaged, the overcenter position of the pin 46 is a stable.

one. I

Figure 6 shows the actuator bar and spring in an intermediate position in which the actuator bar is being lifted. In the position shown, the coil spring is substantially relaxed with the coils engaging one another. In lifting the actuator bar above the position shown in this figure, the coil spring serves to push or lift the bearingarm upwardly until the pin 46 on the gear 49 reaches top center and moves slightly beyond to the overcenter position shown in Figure 8. This position of the'pin 46 is also a stable one inasmuch as further upward movement of the actua tor bar is stopped by means of an enlarged tooth 57 provided at the lower end thereof, the tooth wedging against the gear 55. i

It will 'be noted that the shaft 32, to which the two aligning pin actuator cams are affixed is used to journal the gear 55, this being a matter of convenience. The gear merely idles on the shaft, however,- being held thereon by a snap ring 58, see Figure 5.

The raising and lowering of the feed roller to clear the aligning pins for loading purposes also serves to latch and unlatch a floating guide plate 59. This plate is pivotally mounted for floating, rocking motion about an axis which extends across the register parallel with the grip roller at the discharge side thereof. The respective opposite ends of the guide plate 59 are received in journal apertures 60 which are formed in tabs 61 extending upwardly from the respective upper edges of the two side plate 18 of the chassis. The guide plate presents a lead' ing edge 62 toward oncoming forms. The plate is interleaved between forms, the form or forms passing under-' neath the plate being directed downwardly into the storage compartment and the form or forms passing over the guide plate being directed through the discharge slot 16 onto the top of the lid of the register. During the opera- =tion of the machine the leading edge of the guide plate rides upon the forms, or form if only one record copy is desired, which are being advanced by the feeding mecha nism of the register. Inasmuch as the lines of perforations in oncoming forms can become fouled on theleading edge of a loosely held guide plate, the present guide plate is arranged to be rigidly clamped during operation of the register as illustratedin Figure 7. Under these conditions the guide plate rests upon tabs 63 which are turned inwardly respectively from each of the side plates of the chassis. The plate is held down against the tabs 63 by tabs 64 which are aflixed respectively to the upper surfaces of the bearing arms 43 and which extend in! wardly toward one another from'the arms to contact the opposite outer ends of the guide plate. When the two bearing arms are down in form gripping relationship as shown in Figure 4, the respective tabs 63 and 64 are spaced apart just far enough to accommodate the respec tive ends of the guide plate and to clamp the plate rigidly, there between. This holds the plate so that it cannot be moved by the oncoming lines of perforations. It is found that the forms therefore slide over the leading edge instead of pivoting it into a jamming position.

If the guide plate were held by the tabs 63 and 64 when the bearing arms are in their lower positions, it would make it difficult to thread the forms which are to be directed to the storage compartment. For this reason, the tabs 64 are placed upon the bearing arms so that they lift with them when the bearing arms are raised for loading purposes. This permits the leading edge of the guide plate to be swung up into the position shown in Figure '9, in which position a substantial opening is provided to receive the form or forms which are to pass underneath of the plate and into the storage compartment.

The leading edge of the guide plate has appropriate slots in it to provide the necessary clearance for the aligning pins, the feed discs, and for the grip roller lift cams 24. Immediately below the guide plate 59, a plate 65 extends across the register, the latter plate being secured to and extending between the respective side plates ofjthe chassis; Plate 65 is slotted in order to provide the necessary clearance for the elements of the feeding and aligning mechanism. The plate 65 constitutes a table for directing the forms moving to storage underneath guide plate 59. At the opposite of the feeding and aligning mechanism, plate 65 serves to support the writing platen 14, the platen being hinged to the, plate 65 so that it may be raised, pivoting upon an axis which substantially parallels the grip roller.

To load the register, the lid is opened and the actuator bar 50 raised by pulling on the finger tab 51. This does two things; it raises the. feed roller to provide ample clear ance for engaging the forms on the aligning pins and it also frees the guide plate 59 so that it may be swung up to facilitate the threading of forms beneath it. If only one form is to bedirected into the storage compartment, the guide plate. is released after the lowermost one of the superimposed forms is in place. The other forms are simply laid on top of the guide plate. The loading is com:

pleted' and the register ready for operation upon sliding the actuator. bar to its lowermost position and closing the lid.

means to move selectively said grip roller from a lower position in which it is operatively associated with said feeding and aligning mechanism to an upper position in which it is raised with respect to said mechanism to facilitate loading of the register, said means comprising pivotal means to mount said grip roller for swinging movement between said two positions, an actuator bar silidably mounted at a side of said chassis, a gear rack formed in a side edge of said actuator bar, an idler gear inter-meshed with said gear rack, a second gear intermeshed with the first mentioned gear, a spring connector on said second gear, the actuator bar and the two gears interrelated so that said spring connector is moved from a lower position to an upper position upon the sliding of said actuator bar from a lower position to an upper position, and a coil spring interconnecting said spring connector and said pivotal means, said coil spring being of such length that it is under tension to urge said pivotal means downwardly when said actuator bar is in its lower position and is under compression to push said pivotal means upwardly when said actuator bar is in its upper position.

10. In an autographic register having a chassis mounting feeding and aligning mechanism and having a grip roller extending transversely of the register above said chassis, means to move selectively said grip roller from a lower position in which it is operatively associated with said feeding and aligning mechanism to a raised position in which it is spaced above said mechanism to facilitate loading of the register, said means comprising pivotal means to mount said grip roller for swinging movement between said two positions, a spring connector disposed below and in spaced relationship to said pivotal means, manually operable means for moving said spring connector between a lower position and a raised position through a vertical distance greater than the distance between the two position of the grip roller, and a coil spring interconnecting said spring connector and said pivotal means, said coil spring being of such length that it is under tension to urge said pivotal means downwardly when said spring connector is in its lower position and it is under compression to push said pivotal means upwardly when said spring connector is in its upper position.
