- In Germany June 5, 1937 13 Claims.

This invention, relates generally to improvements ln paper feeding devices and more particularly to novel controls for bill feeding in record control printing machines.

The main object of the invention is the provision of improved devices for controlling the spacing of a continuous record sheet so that bill forms thereon are positioned to receive lines of address print and item print in certain selected areas on A the forms. 'Ihe forms usually contain a preprinted heading and other printed information which limits the area in which record controlled printing may be received. Record cards are arranged in groups relating to one customer or one source of business and these cards are sensed to control the printing of a bill. However, there are times when the number of cards in a group exceeds the number of lines provided for the reception of such data on one bill form. The devices of the present invention are provided with automatic feeding controls for carrying the extra items over to the proper position on a second form after the capacity of the rst form has been reached.

Another object of the invention is the provision of means for automatically' printing a progressive total at the end of a form containing an incomplete group of items. A feature of the invention is the automatic spacing of the bill form, either on the occurrence of a group change or on the completion of item printing in the area a1- lotted to it,-to present the'total print receiving position of the form at the printing line.

Another object of the invenion is the provision of flexible controls for the bill feeding devices whereby various arrangements of the address, item and total printing positions may/ bemade by the operator.y 'I'he feeding devices are adjustable for various lengths of forms and also for preselecting the lines on` which address printing is to start, the amount of space to be provided between'such address printing and the first line of item printing, the number of lines of item printing to be received on each bill, the spacing between the last item impression and the total, and the distance between the total and the first line of address printing.

A further object of the invention is the provision of electrical controls which may be plugged before the machine is operated to control the arrangement of printing on a bill form. The devices include a commutator, the segments of which are related to the lines on the bill form. Each segment may be made effective by plug connections established by the operator to suit the arrangement desired on the bill. Associated with the commutator are three magnetic clutches, one for controlling the starting and stopping of the feeding devices, the second for connecting the' commutator with the feeding devices and the third for resetting the commutator.

(Cl. IS7-433) Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanying drawings whether Within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

Fig. 6 is a perspective view showing one denominational order of the accumulating devices.

Fig. 7 is a sectional elevation View of the printing devices.

The controls for the feeding devices comprise a magnet I (Fig. 1) which is energized at diiferential times to establish a connection between the operating motor 2 (Fig. 4) of the printing machine and the platen 3 (Fig. 1). The holder for the magnet I is loosely mounted on a shaft 5 and carries a gear 6 meshing with a gear mounted on a shaft 'l which is-continuously operated by the motor 2 so that the holder i and magnet l rotate continuously during operation of the machine. The holder il is formed in the shape of a cup in which the magnet I is assembled. The edge of the cup holder is provided with a friction clutch ring 4' which is adapted to contact with the side of a gear Wheel 9 which is the armature of'the magnet I. Armature gear il is attached to the shaft 5 so that, when the magnet i is energized, the gear is frictionally connected to holder 4 and shaft 'l and transmits the driving movement through shaft 5 to differential gearing I0, II and I2 connected to the platen roll 3. The operation of this differential gearing is described in greater detail hereinafter. In order that the holder i and the clutch magnet I may be effective to drive gear wheel 9, it is made shiftable-along the shaft 5 so that, when the magnet is energized, the entire unit shifts axially to the right to contact with armature gear 9.

On this same shaft 5 there is mounted another cup holder I3 containing a clutch magnet I3. This holder I3' is riveted on the armature gear 9 wiring diagram spots and ring 2| are embedded in a stationary shaft 1.

commutator disc 22 made of insulation material which is fastened to the machine frame 24 by means of screw bolts 23. The contact spots 20 are each formed with a recess or plug socket so that by means of plugs 25 selective connections may be established with the wiping brush devices I8 and I9 as described more fully hereinafter with reference to the wiring diagram.

The armature gear 9 controlled by magnet I and the disc I4` controlled by magnet I3 are both under the influence of separate locking devices with which electrical unlocking elements are coordinated. Pawls 30 and 3| (Fig. 2A) cooperate A with teeth 28 on armature 9 to prevent movement of the gear in either direction. These pawls` are carried by an armature 29 operable to release the pawls when a magnet 26 'is energized. The

other armature disc I4 is provided with a single ratchet tooth 32 with which

pawls

33 and 34 of an armature 35 cooperate as controlled by a magnet 21. Armature I4 and the cooperating stopping

lmeans comprising pawls

33 and 34 constitute a single revolution clutch. In Figi 2A it is seen that energization of

magnets

26 and 21 serves to free the armatures 9, I4 so they may rotate as urged by the clutch connections established by the magnets I and I3.

' Holder I3 is provided with a friction ring I4' for engaging the disc I4 when the magnet I3 is energized. This connection serves to attach the brush holder I1 to the shaft 5 which is rotated when magnet I is energized.

A second magnet 36 (Fig. 1) is provided for acting upon the armature disc I4. This magnet 36 is located in a cup holder 36' which is loosely mounted on the shaft I5 and connected by means of

gears

31 and 38 with the'continuously rotating Holder 36 is provided with a friction ring 31 adapted to cooperate with armature disc I4 to restore it and the connected brush holder I1 to the normal position when magnet 36 is energized. y l

In order that current may be conveyed to the magnets I, I3 and 36, the holders inwhich they` are located are provided with pairs of contact rings 39 on which current conducting brushes 40 wipe to provide a continuous path along which the energizing impulses may be carried.

The gearing I0, II and I2 between the shaft 5 and the platen 3 is of a differential form permitting the platen to be moved forward or backward during operation of the machine to correct the 1ocation of the record sheet should the printing line creep to an inaccurate position. In the normal condition of the parts the large gear yI2 carrying the planet gear I2 is locked by a pawl 4| which may be released manually or shapedin the form of a ratchet to permit forward turning of the platen 3 by hand. The operator may grasp the knurled outer surface of the drum |2a attached to `gear I2 to rotate the platen manually.

The operation of the devices will now be described With reference to the wiring diagram (Figs. 4 and 4A), assuming that settings have l21` an axial movement of the disc I4 and establishes been made to space the printing on the forms as represented in Fig. 3. It is noted that an example is assumed wherein the number of item cards of the first group exceed the allotted number of item lines provided on one form.

'Ihefeed controlling commutatordevice 22 is proportioned with a capacity of |00 switching points to accommodate forms varying in length up to one hundred line spaces. Therefore, the fixed insulation disk 22 is provided with a hundred contact spots and plug sockets 20 designated 0 to 99. During one complete revolution of brush `.holder I1 and brush I8, it is possible to eiect one hundred diierent contact closures for initiating starting or stopping of the sheet feeding devices, starting or stopping of the brush moving devices, the resetting of the brush I8, and the printing of a total. Any of these operations may be selected to occur when any line of a form is at the printing point, by merely plugging the control devices to the desired contact spots 20 related to the lines at which a change in feed control is to take place.

For example, in Fig. 3 the forms are seventeen lines in length, with two address lines, a space of five lines to the first line of item print, a space of five lines devoted to item printing and a space of three lines between the last item and the total impression. The spaces between machine controlled printing impressions are used for a preprinted bill heading and receipt information suitable to the business concerned. Of course, it is understood that any other arrangement of the lines of print may be made on the forms; but assuming that the form described is the one desired, then plug connections are made to the contact spots 20 designated 1, 6, 10, 13 and 17, whereby there is established the time of operation of the various sheet feeding and printing controls about to be described.

Operation yof the machine is started by closing the main switch HS (Fig. 4), thereby energizing the brush operating magnet 21 and the clutch magnet I3. Magnet 21 (Fig. 2A) then attracts the armature 35 to disengage the pawl 32 from the disc I4 and armature 35 also closes contacts At the same time, magnet I3 (Fig. 1) effects a connection of the brush holder I1 with the continuously rotated shaft 1, providing the magnet I is energized to close the clutch connections between holder 4 and armature gear 9.- The energization of the magnet 21 is effected by means of a circuit including line 42 (Fig. 4A), contact 22a, wire 43, switch 44, magnet 21, wire 45 and line 46. Magnet I3 is energized over a circuit following a path through line 42, wire 41, upper contacts 22e, switch 48, wiping

contacts

39 and 4|) at the magnet I3, magnet I3, Wire 49 and line 46.

The start key AT (Fig. 4) is then depressed to operate the machine motor by'closing a circuit through the motor coupling magnet KM and the motor relay MR. These motorcontrol magnets are maintained in energized condition by the cam contacts LI and the motor contacts MRb associated with the relay MR. It may be assumed that the record cards are already in the machine so that the well known upper and lower card levers are operated and the associated lever contacts 0K5 and UK5 are closed. The

`magnet KM and relay MR remain energized .as-long as cards continue to pass through the machine because then whenever the cam contacts LI open, the card lever contactsl 0K5 are heldclosed. Upon energization of the relay MR, 75

`L3I is closed and magnet 26 is energized by themotor2 starts to rotate and stops only after means of the following circuit: line 42, contact 22a, contact 24h, switch 56, contacts VRGc, switch 6I, cam contacts L3! lower contacts 2 l a, magnet 26, and line 46. Magnet 26 (Fig. 2A) then attractsvthe armature 29'and closes the contacts 26 thereby establishing a circuit through the feeding control magnet I. The circuit through f magnet I includes line 42, contacts 22a and 24h,

' shaft 5v and thereby actuates gearing i0, II and I2 to turn platen 3. -The operation of platen 3 is`effective for only one line -space because the energization of magnet 26 is so short that the pawls 20, 3l engage the armature gear 9 after one step movement. I

After the record sheet is line spaced, the second address line is printed. This is done While the brush holder Il is positioned with the brush i3 (Fig. 4A) contacting the spot 20 designated 1 on the commutator 22. After the second address line is printed, cam contacts L34 close to energize a relay R2I through a circuit including line 42, contacting ring 2l, brush I9, brush frame il, brush I8, contact spot 20 designated 1, plug wire 53, plug socket 54, cam contacts L34,- relay R2I and line 46. The relay R2I establishes a holding circuit through the connections including main line 42, wire 55, cam contacts Tl 6, wires 56, 51, contacts 2lb, relay R2I and line 46. The energization of relay R2I closes the relay contact 2Ia and causes energization of magnet 26. This serves to condition the feeding devices for another line spacingl operation. The circuit for energizing magnet 26 follows a path through line 42, contacts 22a and 24h, switch 50, wire 58, upper contacts 2Ia, magnet 26, and line 46. The magnet 26 then closes the associated contacts 26 and causes energization of the clutch magnet l through the following connections: line 42, contacts 22a and 24b, switch 50, wire 52, contacts 26'., wiping

contacts

39, 40, magnet I, wire 45, and line 46. Line spacing operation continues-in this fashion until the brush I8 strikes the contact spot 20 designated ,6 on the commutator 22. Then the relay R24 is energized through a circuit including line 42, contact ring 2l, brushes I9, It, contact spot 20 designated 6, plug wire 59, plug socket 60, contacts 2Id, upper contacts 24a, relay R24 and line 46. 'Relay R24 then operates lower contacts v24a to close a holding circuit owing as iolows: line 42, contacts 26h, cam contacts TH, wire 6I, lowercontacts 24a, relay R24, and line 46. It should be noted that the'upper .and lower contacts 24a are arranged so that the lower contactsare' closed before the upper contacts open. The energlzation of relay R24 causes the opening of the contacts 24b in series with the magnets I 26 falls toward the gear 9 toengage pawls 30 and VIl with the teeth 26 to hold the platen in position.

The diii'erential line spacing operation described hereinbefore begins shortly after the printing of the second address line at the time the cam contacts L34 close and continues until shortly before the printing of the rst item.

Before the end of the third machine cycle (i. e., the rst item printing operation) the relays B2i and R24 are denergized due to the opening of the cam contacts TIS and TI'I. At the beginning oi the next machine cycle, cam contacts L3! close to effect another line spacing operation. Four more such line spacing operations (Fig. 3) are initiated as item printing takes place. At the end of the last line spacing operation, the brush E8 rests on the contact' spot 2B designated 10 and thereby relay R23 is energized to initiate spacing to the total line. The relay is energized over a circuit including line d2, contact ringEl, brushes I9, i8, Contact spot designated 10, plug wire 62, plug socket 63, contact 2te, switch 613, relay R23 and line 46. Relay R23 then closes a holding circuit through line 42, wire 55, cam contacts TIG, wire 56, contacts 23a, relay R23,'and line t6. Associated with relay R23 is another` contact 23e (Fig. 4) which is normally closed but when opened by the relay initiates a series of controls in the tabulating machines similar to those eiected on the occurrence of an automatic group change and total printing operation. When contacts 23e are opened, the opening of cam contacts Td causes a deenergization of a relay UGR and the suspension of card feeding operation. Before explaining the operations brought about by the opening of contacts 23e the effect of an ordinary group change `will be described brieiiy.

When the record cardsl 3a (Fig. 3A) are fed through the machine, they pass successively rst under a series of upper brushes UB (Fig. 4) and then onecycl e later under a series of lower brushes LB. If the group numbers perforated in the cards agree, circuits are maintained as follows: line 42, upper brush UB, group control relay GR, lower brushes LB, impulse distributors 65, card lever contacts 66 and line 46. Relays GR establish holding circuits throughl related holding coils GR by the closure of associated contacts GRb along connections including line 42, cam contacts L5, contacts GRI), holding coil GR', wire 6l and line 46. Relay UGR remains energized as long as cards with similar group@ numbers pass under the upper and lower brushes.

`At this time the circuit vfor relay UGR ows through line 62,1wire 68, relay UGR, cam contacts T4, wire 69 and line Q6. During the short time that the contacts T4 are open, the circuit is maintained through contacts GRa closed by the group control relays GR as long as they are maintained energized. This running circuit for relay UGR includes contacts 23e, a series of contacts GRa, a card lever contact 0K2, wire 69 and line 46. Therefore the4 deenergization of relay UGR may take place in either of two ways; if the contacts 23e are opened, or if one of the group control contacts GRa is open during the breaking of the cam contact T4. 'I'he former is the case if the allotted item printing area on the form is reached before the sensing of an entire group of cards, thus. requiring that another record form ofthe continuous sheet bebrought into itemreceiving position. The latter is the case if the 'end of a card group is reached before l the item printing area of -a form has been used. It is possible that relay UGR may be deenergized by the simultaneous operation of both controls.

As soon as relay UGR is deenergized the assorelay R21 and line 46.

ciated contact UGRa is closed to energize relay VRG. The circuit through relay VRG may be traced through line 42, wire 111, contact UGRa, relay VRG, wire 69, and line 46. Relay VRG then closes a holding circuit through line 42, wire 1I, contacts R3d, wire 12, contact VRGa, relay VRG, wire 69 and line 46. When relay VRG is energized, its associated contact VRGb is closed to energize a relay AR2 through a circuit including line 42, contact VRGb, cam contacts L9, relay AR2, Wire 13, and line 46. A holding circuit for this relay then flows as follows: line 42, wire 1I contacts R311, conductor 14, Wire 15, contacts ARZb, holding coil AR2H of relay AR2, wire 13 and line 46. Associated with relay AR2 is a contact AR2a which is closed when the 4relay is energized and -thereby initiates the energization of another relay BR2 through a circuit passing along line 42, contacts VRGb, cam contacts'LIU,

left side of contacts ARIa, relay contacts AR2a,

left side of contacts BRZb, relay BR2,

wires

16 and 13, and line 46. Relay BR2 then closes the right side of contacts BR2b to establish a holding circuit owing as follows: line 42, wire 1I, contacts R303, wire 14, right side of contacts BRZU, relay BR2,

wires

16 and 13 and line 46. |The left side of contacts BR2b break only after the closure of the right side of these contacts,

With the closing of contacts AR2a, the spacing control relay R21 is made elective when a plug wire 18 is connected between socket 11 (Fig. 4) and socket 19 (Fig. 4A). The complete circuit includes lines 42, contacts VRGb, cam contacts L10, the left side of contacts ARIa, contacts AR2a, socket 11, plug wire 18, socket 19, Wire 18', -The holding circuit over relay R21 is established through `line 42, wire 55, contacts T16, wires 56, 51, contacts 2lb, relay R21 and line 46. Through the energization of relay R21 the doublecontacts 21a are shifted, thereby energizing the line space relay magnet 26 over the following circuit: line 42, contacts 22a and 24b, switch 50, wire 58, upper side of contacts 2Ia, magnet 26,

wire

4,5 and line 46. Then magnet 26 again closes the associated con-y tact 26 to energize the clutch magnet I in the manner-described hereinbefore. The unlocking magnet 26 releases lthe armature wheel 9 and magnet I clutches the latter to the driving means to operate the platen 3 through a feeding move- .ment which continues until the contact brush I8 closes the associated lower. contact 24a, it establshes a holding circuit as follows: -line 42, contacts 26h, contacts TI1, wire 6I, the lower side of contacts 24a,I relay R24, and line 46. Relay R24 then operates to open the associated contacts 24h to de energize feed magnets 26 and I. This serves to interrupt the paper feed operation, because` armature 29 of magnet 26 drops to catch the

pawls

30, 31, in the teeth 28 on the armature wheel 9. i

Card feeding is automatically stopped after the printing of the last item in the item printing area, and only started in operation again after a total takingcycle has been effected. When the main switch HS was closed, the usual card feeding clutch magnets kyIl' KM was energized over the following circuit path: line 42, wire 82, magnet KKM, contacts VRGi, and line 46. Clutch magnet KKM remains energized during address and item printing and is released only during the last item printing cycle by the Vopening of contacts VRGi. After a progressive total is printed at the bottom of the form, the relay R25 is energized in the following circuit: line 42, contacts VRGb, cam contacts LID, right side of contacts ARIa, plug socket 83, plug wire 83a, socket 84 (Fig. 4A), relay R25, contacts 26a, and line 46. A holding circuit is established through relay R25 along line 42, Wire 55, contacts T16, wire 56, contacts 25a, relay R25, contacts 26a, and line 46. Relay R254 acts to close associated .contacts 25h and magnet 26 lis energized through line 42,

contacts

22a and 251;, switch 50, wire 58, contacts 21a, magnet 26 and line 46. Through the energization of magnet 26,y contacts 26 are again closed to cause the energization of clutch magnet I. The armature wheel 9 is then released by magnet 26 and engaged by magnet I so that platen ,3 is driven to space the record sheet.

When the cam contact L9 is closed, relay ARI is made effective through connections including line 42, contacts VRGb, cam contacts L9, contacts BRZa, relay ARI, Wire 13, and line 46. The holding circuit through relay ARI flows as follows: line 42, wire 1I, contacts R311,

Wires

14 and 15, contact ARIb, holding coil ARIH of relay ARI, wire 13, and line 46. Upon energization of relay ARI, the contacts ARIa .are shifted and socket 63 again becomes alive to energize relay R25 as explained hereinbefore. relay BRI is energized through line 42, relay contacts VRGb, cam contacts L18, the right side of contacts ARIa, left sideu of contacts BRIb, relay BRI,

wires

16 and 13, and line 46. A holding circuit over relay BRI flows through line 42, wire 1I, contacts R3d, wire 14, Wire 85, right side of contacts BRIb, relay BRI, and

wires

16 and 13 to line 46. As soon as cam contact L18 is closed, relay R3 is energized over a circuit through line 42, wire 86, cam contacts TI, cam contacts L18, relay contacts BRIa, relay R3 and line 46. Relay R3 then closes a holding circuit through the closed contacts R3a. Energization' fing is initiated by relayR25 when this relay is energized through connections including plug sockets 83 and 84.A Such feeding movement continues until relay R22 is ,energized by a circuit initiated when brush I8 strikes the contact spot 20 designated 11. The circuit through the plug spot 17 may be traced through line 42, contact ring 2I brushes I9, I8, contact spot 20 designated 17, plug wire 81, socket 88, relay R22 and linel 46. The relay closes a holding circuit through line 42, contacts 26h, cam contacts T11, wire 89, switch 96. Wire 91, contacts 221), relay R22 and line 46. Relay R22 is made effective and contacts 22a are opened to deenergize magnets I, 26 and 21. Armature 29 of Vmagnet 26 thn drops to engage wheel 9 to lock it andstop operation of the platen. Armature disc I4 associated with magnet I3 isalso stopped by the action of magnet 21 when the tooth 32 strikes the In addition to this, the f pawls 33 and 34 on armature 35. p Through the 75 position.

Disc I4 and armature 35 (Fig. 2A) are shaped so that contacts 21 are held closed throughout A most of the timethat the disc is rotating. Contacts 21' are not opened while the end of the armature is resting'on the concentric part of the periphery of the disc I4 and they open normally a short time before projection 32 passes between the locking faces of.

pawls

33 and 34. As soon as contacts 21 open, the brush resetting magnet 36 is deenergized. This arrangement makes it possible for magnet 36 and armature I4 to be disengaged shortly before the armature is locked in normal position. The circuit through the resetting magnet 3 ows through line 42, Wire 41, lower side of contacts 22e, contacts 21', wiping contacts 39' 40, magnet 36 and line 46.

When the armature disc I4 is locked in normal position (Fig. 2A), the brush holder I1 is again infthe starting position wherein brush I8 rests on contact spot 20 designated 0 (Fig. 4A) and relay R26 is energized through line 42, contact ring 2l, brushes I9, I6, contact spot 26 designated 0, wire 92, contacts 23d, switch 93, relay R26,

and line 46. When the relay R26 is energized it opens the associated contacts 26a and 26h to deenergize relays R22, R24 and R25. Relays R22 and R24 release contacts 22a`and 24h so that they again close, and the clutch releasing magnet 26 is energized over a circuit including line 42, contacts 22a, 24h, switch 50, conductor 58, upper side of contacts 2Ia, magnet 26, and line 46. Through the energization of magnet 26, the f eed clutching magnet I is energized by closed contacts 22a, 24b, switch 56, wire 52, armature contacts 26',and through magnet I to line 46. The brush releasing magnet 21 is also energized through the closure of contacts 22a and switch 44. Coupling magnet I3 is also made effective through the closure of upper contacts 22e and switch 48. Because of these operations, the armature wheel 9 is unlocked so that clutch magnet I is adapted to drive the platen 3. Because the magnet 21 releases the armature disc I4, the brush coupling magnet I3 is also effective so that the brush holder is moved along with the arma- -ture wheel 9. This movement of the brush holder continues until the brush I8 reaches the Contact spot 20 designated "6 showing that the next record form is presented with the rst item printing receiving line in printing position. It may be noted that on this second form a record of the address is not necessary as it is a continuation of the previous form.

When the brush holder I1 reaches the com mutator position designatedl 6, then the relay R24 is again energized because relay R2I `has been held energized by its holding circuit and contacts 2id are closed. Relay R24 sets up its ownholding circuit through lower contacts 24a. Since contacts 24b are opened when magnet R24 -vis energized, magnets I and 26 are again deener encrgization of one or more relays GR so that the control relay UGR is deenergized as soon as cam contact T4 opens. The relay VRG is then energized as mentioned hereinbefore and held energized by its holding circuit. The card feed clutch magnet KKM (Fig. 4) is deenergized at this time so that card feeding is stopped.

Relay R2I is energized throughthe circuit including contacts VRGb and the plug connections including plug wire 18. This relay closes associated upper contacts 2Ia (Fig. 4A to energize magnet 26 and close armature contact 26 so that the clutch magnet I is again energized to start a feeding operation. Paper feeding continues until the contact brush I8 touches the contact spot 20 designated "13, 'Then the record sheet is in a total printing position and relay R24 is energized and related contacts 24b open to deenergize magnets I and 26, so that the sheet feeding operation is terminated. During the movement of the record sheet fromthe position corresponding with the 6 designation on the commutator to the "13 spot on the commutator, it passes through the 10 position wherein the brush I8 passes over the contact spot 20 designated "10. However, no energization of the connected relay R23 results because the previous group change operation served to energize relay R2! and thereby open contacts 2Ie which are in series with relay R23.

After the printing of the group total, relay R is again energized and the associated contact 25h is closed to energize magnets i and 26, so that feeding is started again and continues until brush I8 reaches the contact spot 26 marked 17. Then relay R22 is energized and remains in this condition by means of the connections through switch 96, cam contacts TI1 and relay contacts 2Gb. The opening of

contacts

22a and 22c serve to deenergize magnets I, I3, 26 and 21 while magnet 36 is energized. Brush holder I1 is then restored to the starting position by means of the connections established by energized magnet 36.- Although the brush I8 then touches the contact spot 20 designated 0, relay R26 is not energized because relay R23 is not effective to close contacts 23h. This brings the feeding deivices back to a starting position so that operations may be initiated under control of the following group of record cards.

There are times when it is desired to use a form for each item recorded on the separate record cards. When such control is desired, a single plugging connection is made with a contact 'spot 20, such as the connection made with spot designated 17 in Fig. 4A. Furthermore, the positions of

switches

56, 5I, 64, 9D and 93 are reversed so that switches 50, 5I and 63 are opened and switches 64 and 96 are placed in the closed positions shown by dotted lines in Fig. 4A.

The other switch 94 shown at the top of Fig. 4A

is closed when single item recording is desired. Then paper feeding is operated each time an item is printed and is interrupted when the brush holder I1 carries the brush I8 into contact with the spot 20 plugged to the feed control connections. These connections serve to bring the brush holder back to the starting position..

The amount of space between items may be determined automatically by setting controls for selecting one, two or three spaces between record l lines on forms. Referring to the top of Fig. 4A, it is seen that in addition to the switch 5I, two other similar switches 5I' and 5I" are coordinated with cam contacts L32 and L33 which have the same eiiectas the other cam contact L3l. The cam 4contacts L3| and L32 and L33 (Fig. 5) are timed in such a waythat they become. operative in succession to initiate one,

two or three line spacing operations by energizing the connected unlocking magnet 26 one,

two or three times within a single operating cycle.

Operation of this magnet 26 involves a corre# spending energization of the clutching magnet I to drive the p1aten3 through the required distance. The general construction of the item and total printing devices used in the machine are well4 known in the art and described in Patent 1,976,617, consequently there will be given here# vin only a brief explanation of such parts as are ing clutch collar |1| into engagement with the clutch collar |19 on accumulator gear |80.' The -gear is turned a differential amount according to the time that magnet AM is energized. Gear |80 meshes with a gear 209 carrying brushes 2|0 which cooperate with commutator segments 2|| to give a reading of the total amount accumulated on total taking operations. reading device isset yforth in greater detail in the Lake Patent 1,379,268 granted May 24, 1921. When any magnet AM is energized, it causes contacts to close, energizing a printer magnet PM (Fig. 7) to select the type corresponding to -the entered data. In'this fashion the accumulated or entered items may be listed.

In Fig. '7 is shown 'the printing mechanism through which the type bar 2|2 is positioned relatively to the platen 3 to bring the proper type 2|8 opposite the platen. The listing shaft 265 driven by the tabulating motor is provided with a cam 213 cooperating with a roller 3||a carried by an arm 3| operatively connected to a shaft 308. As the cam rotates, shaft 308 is rocked in a clockwise direction and an arm 301 secured thereto andlinked at its free ends to printing cross-head 304 serves to raise the type bars 2|2 in synchronism with the movement of the record 2|1, normally holding a stop pawl 223.

When the pawl is so released, itis spring operated to engage the ratchet teeth 2|6 formed on the type bar 2|2 to' prevent further upward movement of the type bar, thus holding a particular type 2|0 in front of hammer 224 which is provided to inipel the type against the platen.
