w. P. scHARR PAPER FEEDING DEVICE Filed July 4, 1 959 Patented Sept. 3, 1940 UNITED `S'IATIEZS -m'rlau'r OFFICE PAPER' 'FEEnmG DEVICE y York Application July 4, 1939, Serial No. 282,791 In Germany July 11,- 1938 1o claims. l (c1. iov-129) This invention relates generally to paper feeding devices and, more specifically, to split platens for accounting machines wherein separate recfor receiving lines of item and total impressions, and be line spaced between items and fed with" l a long feed 'after total recordings so that the rstline of a succeeding form is brought into print receiving position; The other section of the platenI carries a continuous strip or collection list whereon the items -and totals are recorded without long open spaces between the successive recordings related to different bills.

Heretofore separate uncoordinated feeding devices have been applied to divide platen sections, but in the present case, the platen parts -are coo ordinated because asingle driving means` is used to operate both portions of the split platen.

When printing items on forms such as bills, there are times when it is desired to print an additional record of, the list of items vand totals appearing on a plurality of bills. Such a list is usually called a collection list. Of course, the

size of the bill forms is constant, but the number7 of itemsA recorded thereon varies, so that there is often a large space under the last item or total on a bill. If the collection list or strip were to be fed the same as the bill sheet there` would be long unused sections thereon corresponding to the unused' parts of the bills. Therefore, the

devices of the present invention are provided to disconnect the feeding connections of the strip during the time that a long feeding operation is imparted to the bill sheet, and, in this way, the printed data on the strip is spaced with the lines of. recording followingdirectly under each n other. There is a slight increase in the distance between the lines of recording after each total vline of recording.B This is done to distinguish separategroups of items and associate the items and totals relating to a particular bill.

5 .An obiect'of'the invention is to provide a divided platen which is adapted for use in the ordinary way as a long unitary platen with a surface that is substantially contiguous. Therefore, the divided platen may support a single 50A sheet to receive impressions across the full width, but it is also suited for holding separate sheets which are to be moved differentially. j

AAnother object of the invention L.is to provide a split, platen with drivingc controls that are co- 55 ordinated with agrecord controlled machine S0 that the platen sections are automatically controlled to be fed in line spacing after item print-- ing operations and shifted with a long feed after total printing operations.

A further object of the invention is the pro- 5 vision of separate but coordinated paper feeding rollers with adjustable controls cooperating with one roller so that different sized forms or bills7 of different lengths may be fed thereon, and other adjustable controls cooperating with the 10 other roller so that a variable predetermined extent of feed may be imparted to the strip on said second rollr following a reception of a total,

impression.

A still further object of the invention is the'lii provision of a divided platen whereinl one section or part is fed through connections to the other part, with means for Acle-clutching the driven part from the driver. A magnetic clutch serves. to connect the driving part to a main operating zo means, and another magnetic clutch may be operated to disconnect the second part from the part connected to the main operating means.

It is also an object of the invention to provide adjustable cams for operating contacts inI series 25 withvthe magnetic clutches controlling the feeding connections to the sections to the platen. Certain of these cams are coordinated and synchronized with the line spacing and long feeding movement of one section of the platen to determine the length of bill forms. 'I'he other contact operating cams are driven on total taking operations to control de-clutching of the listing section of the platen while the other section is oper- `ative to eject a bill; The cams associated with 35 the listing section of the platen may be lalziiusted to select a, vpredetermined spacing of the list 1 afer a total has been recorded thereon.

suchv as that disclosed in the Lake Patent No. 1,976,617, issued October 9, 1934.

The two platen portions or sections 2 0 and 2| are supported on the platen shaft 22 that extends 55 embodiedfi-n 5g j and controlled by a record controlled machine Aso 4oss

through carriage side frames 23 and 24; On the right end, the shaft is supported on a ball bearing 25 attached to the right side frame 24. The left end of shaft 22 is supported by another ball bearing 26, the outer race of which is secured to the left end of platen portion 20.

The right section 2| of the split platen is supported on shaft 22 by means of a pair of circular end members 21 and 28 the latter of which is centered on the shaft but connedbetween bearing 25 and a shoulder on shaft 22. Section 2| is secured to shaft 22 by means of a pin 29 extending through the hub of end member 21. Therefore it is apparent that the right section 2|, which is the section that carries the bill form material, is permanently connected with the platen shaft andpartakes of all movements imparted to the shaft.

The other section 20 is the portion of the platen adapted to carry the collection list strip and forL this reason is arranged to be readily disengaged from the platen shaft 22, but normally connected therewith to move in synchronism with the line spacingmovement of section 2|. The right end of section 20 is rotatably mounted on shaft 22 by means of a ball bearing which is confined between the end of member 21 and a shoulder on an annular ring 3| attached to the end of section 29.

As shown, the portions 20 and 2| are illustrated as being separated by a space 32 appearing at the center of the platen. 'I'his space 32 is exaggerated for purposes of illustration, for the surfaces of the two parts of the platen may be made substantially contiguous so that a type impression may be effected at the intersection of the parts of the platen when a single wide sheet is used. Y

The left end of section 20 is provided with a cylinder 33 surrounding the left end of shaft 22 but separated therefrom. This cylinder is attached to the end of section 20 and extends through a ball bearing 34 which is fastened in-4 side a housing 35 attached to the left sideframe 23 of the'carriage. Fastened to the left end of cylinder 33 by means of feather pins 36, is a circular member 31 carrying the outer race of ball bearing 26, mentioned hereinbefore as being the left bearing of shaft 22. From the foregoing description it is apparent that platen section 2|) is free to rotate with respect to shaft 22 'because bearings 26, 30, and 34 are allowed to turn freely and at the same time serve as sup ports for the left end of the shaft.

Connections are provided to gear the left section 20 to the left end of the platen so that it is normally clutched and conected` therewith. At the left end of shaft 22, a crown gear 38 is pinned on the shaft. The teeth on this gear cooperate with the teeth of a similar gear 39 fastened to the armature ring 40 on a hand wheel 4| loosely mounted on a stub shaft 42.v Extending inwardly from the armature plate 40 is a pin 43 engaged in a slotted fiange 44 extending from the member 31 attached to the cylinder 33. Therefore it is apparent that a driving connection exists between the platen shaft and the section 2li through gear 38, gear 39, armature plate 40, pin 43, flange 44, member 31, and cylinder 33 attached to section 20. This connection remains in effect as .long as the teeth of the gears 38 and 39 remain` in mesh, as they areurged to do by a compression spring 45 tending to move gear 39 towards the' right. A magnet 46 is provided to counteract the pressure of spring 45 and draw the armature and connected gear 39,to wards the left to disengage the driving connection. This magnet is mounted in a cup-shaped holder 41 which is fastened to a bracket 48 attached to the left side frame 23 and thus made 5 stationary with respect to the platen. When magnet 46 is energized it attracts armature 40 and slides the connected gear 39 towards the left, carrying the shaft 42 along therewith because it is attached to gear 39 by means of pin 49. 'I'he outer surface of .armature 40 is provided with an annular ring of friction material 50 that is designed to engage the outer lip of cup 41 so that motion of gear 39 and hand wheel 4| may be stopped abruptly when the magnet draws them out of driving engagement.

In addition to the automatic means for disconnecting the platen drive by means of magnet 46, there is also provided a manual device for disconnecting gear 39 from gear 38 This control takes the form of a knurled knob 5| loosely mounted on the end of stub shaft 42. The knob is formed with a ange having a V-shaped extension 52 which normally fits into a groove in a collar 59 keyed on stub shaft 42. A pin |00 holds the collar with respect to rotation, but a slot inthe shaft around the pin, permits the shaft to move axially through the collar. The right end of this collar 53 abuts against the inner race of a ball bearing 54 mounted between the magnet holder 41 and the shaft 42. Therefore, when the knob 5| is gripped and pulled outwardly to shift extension 52 away from the no tch in collar 53 and then supported on the outer surface of collar 53, shaft 42 is drawn towards the left and the teeth of the connected clutch gear 39 are disengaged from'the crown gear 38. l

Hand wheel 4| provides means whereby the platen sections may be rotated by hand. When the clutch connection is established between gears 38 and 39, as shown, theoperation of hand wheel 4| serves to turn both sections 20 and 2| of the platen. However, should the gear connectionsbe l disconnected either through operation of the Y manipulative knob 5|, or through energization of magnet 46, then the hand wheel 4| is not connected to platen portion 2|, but remains connected to the other section 20 through pin 43 which remains in cooperation with flange 44, i, regardless of the position of the armature 48. By this means the collection strip on section 20 may be adjusted or reinserted without disturbing the bill'sheet around portion 2|.

Both platen sections are driven from a common operator by means of connections established with a main operating means. When the main switch S is closed a motor 55 is driven by a circuit through line 330,-wire 56, motor 55, wire 51, feed switch Sl and line 33|. The motor drives ,i a belt 58 on a pulley 59 connected to a shaft 89 on which there is fastened a gear 6|. Gear 6| meshes with a constantly turning clutch gear 62 freely mounted on the end of platen shaft 22. Adjacent to clutch gear 62 is a cup magnet clutch housing 63 keyed to shaft 22 by means of a. pin and slot connection 64. The housing 63 is normally pushed away from the clutch drive gear 62 by means of a compressionspring 65 mounted in oppositely facing annular grooves in i'he parts 62 and 63. This spring serves to hold the housing 63 towards the left abutting against the stop pin 66 in shaft 22. However, the housing carries' a magnet 61 which, when energized, attracts the clutch gear 62 and serves to move the housing u 63 relative thereto so that the friction surfaces on both inner sides engage and form a driving connection.

-It is obvious that the extent of movement iml' parted toA the platen shaft 22 depends upon the time of energization of magnet 61, so that for short, line spacing movements a momentary energization of the magnet is suicient to cause it to shift ahead one tooth space on the usual ratchet and pawl locating means; while for long feeding operations, a sustaining energization of magnet 61.is required.

The automatic split section controls of the disjclosure may be suspended by opening switch SI,

chanical clutch connections are established with the pair of platen sections in such a manner that the bill sheet is fed from form to form while the accompanying strip is line kspaced, In series with the clutch magnet 61 is `a pair of contacts 68 which are closed momentarily ,during each printing operation by a lever. 265 that is vibrated in the tabulator before each printing operationis effected. The line spacing circuit through magnet 61 includes une aslfswitch sl, wire 51, wire 69, magnet 61, wire 10, 'normally closed contacts 1|, magnet 12, contacts 68, wire 56, and line 338. This is a circuit that is closed momentarily so that magnet 61 attracts gear 62 and effects a connection between the main operating means and the platen shaft 22 which at this time is connected to both platen sections 20 and 2 I. -rI'he clutch con-l nection is maintained just long enough to carrythe driven sections so that the ratchet wheel 212 thereon makes one step of movement before the usual detent comes into play to hold it from further movement. r

The described line spacing circuit is maintained through contact 1| for a predetermined number of line spacing operations according to the de-f sired length of bill form. The length of-the bill form is predetermined by the arrangement of a' pair ofadjustable cams 13 and 14 which cooperate with the contacts 1| to regulate the time at which they are to open to stop line spacing and long feeding operation. These cams 13 and 14 are adjustable with relation to each other so that the elevated periphery thereon may be extended or contracted by setting the cams relative to each other and then locking them together bymeans of a pin 15 passing through an aligned pair of the many perforations 16 appearing in the'cams- The insulation block on the lower blade of contacts 1| -is wide enough -to cooperate .with the elevated part of the' periphery of both cams so that it rides along the outer edge of one com and passes over/both cams and along the outer edge of the other cam before dropping into the depression- ,l constantly rotating shaft I8' similar to the shaft Kbetween bothl cams.

The contact operating cams 13 and 14 are moved in synchronism with the movement of the platen by means of clutch connections that are established lby magnet 12 which is energized whenever magnet 61 is energized to cause platen movement. The cams are attached to a. sh'aft 11 bearing one part of a normally open clutch 18 the-'other part of which is slidably mounted on a 60. Whenever magnet 12 is energized it rocks a. lever 18 articulated with the movable part of clutch 18 which then connects cams 13 and 14 to the driving means so that they are synchronized with the movement of the platen.

The combined effect of cams 13 and 14 is to sustain the electrical connnections through contact 1I so that magnet 61 is energized for such a length of time that vthe platen section 2| is connected to the driving means to move to such a degree that the remainder of each bill form is fed after each total printing operation regardless of the number of previously recorded items thereon. f

Attention may be drawn to the fact that the platen section 20 carrying the continuous strip remains connected to the driven section of the platen through gears 38 and 39 during all line spacing operations. However, after a total printing impression is effected on the records, other automatic controls come into play to energize magnet 46 to disconnect platen section 26 from the bill carrying section 2| during mostA of the long feeding operation which is used to eject the bill form. 'Ihese controls include a pair of contacts 80 in series with magnet 46 and a pair of adjustable cams 8| and 82 which cooperate with` the contacts 80 to close them during loig feeding operation. These cams 8| and 82 are sim#l ilar to the other cams 13, 14 in that they are connected together by a pin 83 after being set with relation to each other by a pair of perforav tions 84 therein aligned by the pin. The cams 8| and 82 are attached to thetabulatpr shafty |54 which is turned after each total printing' operad tion. Also attached to the shaft |54 is another contact operating cam 85 cooperating with contacts 86 arranged in series with the clutch magnets 61 and 12. 'I'he effect of cam 85 is to close contacts 86 during the latter part of a total op- ,A

eration and thus provide a sustaining circuit for clutch magnet 61 which holds the drive connection to platen section 2| long enough to eject the bill upon which the total has been printed.

The length of time that this circuit through'.

magnet A61, contact 1|, magnet 12 and contacts 86, is held is governed by the adjusted raised periphery of cams 13 and 14 cooperating with contacts 1I. At the same time that the contacts 86 are closed to initiate the long feeding opera-l4 i tion, contacts 88 are closed to energize magnet `46 so that platen-section 20 is disconnected from the platen shaft and thus is withheld from partaking of the long feed movement imparted to the other platen section 2|. However, contacts 88 are not held closed through the entire length of the long feeding operation because it is desired thata certain amount of space be provided on the continuous strip after each total impression.

This amount of space on a strip may be pr'edeter-v '1,

mined and selected by shortening the effective range -of cams 8| and 82 so that contacts 88 are opened before contacts 1| open, therefore -relay 46 will be deenergized near the end of` the long feed operation and gears 38 and 39 are again engaged while magnet 61 is still effectively connecting the platen shaft to the main driving means.

When the contacts 1| `open during the long feeding operatibn, magnet 61 is deenergized to preventfurther movement of the platen, vbut movement of camsA 13 and 14 is maintained by other electrical connections through contacts 88 which maintain Athe energization of magnet 12 and therefore keep clutch 18 closed to drive the -cams through the remainder of their cycle. The

circuit through magnet 12 at this time includes wire 90. contacts 89, magnet 12, contacts I8 and wire 56 to line 330. Thus magnet 12 is maintained effective until the cams 13 and 1l are brought around to the normal position, in which they are shown, at which time the contacts 89 open simultaneously with the opening of oontacts 8,6 which deener'gizes relay 12 so that the clutch 18 returns to the normal disengaged condition. Then the parts areready for a new cycle of operation with the bill form on platen section 2| in position to receive the first item impression and the strip on platen section 20 spaced a predetermined amount below the last total impression and also in readiness to receive the first item imprint.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to.a single modification, it will be understood that various omissions and substitutions and changes in the form and details of the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit of the invention.
