24 Claims.

'I'his invention relates to printing mechanisms for accounting, tabulating machines or the like and is primarily directed to printing additional matter on a record sheet by auxiliary impression members, such as stencilled plates, matrices, printing plates, orthe like, which are selectively and conditionally positioned at definite cycles of machine operation.l

They present improvements find particular application to machines provided with entry receiving and printing devices which cause to be printed upon a continuous work sheet account data, such as, for example, groups of items with a related total. Printing of the items may be controlled by record cards, the perforations of which represent the items and other cla'ssication data. Such printedaccounts may constitute bills or statements and heretofore, contained no identification data, such as account names., addresses, etc. The present invention provides for selectively feeding to the printing mechanism impression members Y carrying the proper identification data whereby o each account as printed is suitably identified.

Preferably, the impression members are compared with the item entry controlling devices so that printing of the wrong identification data will be effectively prevented,

It is then a broad object of lthe present invention to providefor printing identication or other data by presenting auxiliary impression members to anl impression receiving element, such as a record strip. y

It is a still further object to provide means whereby the impression members are presented to the record strip as an incident to certain ma,- chine operations.

More specifically it is an object of the present invention to identify printed accounts comprising.

a series of items with a related total by present-- o ing a related impression member to a'record strip carrying such printed accounts.

It is a still further object to analyze each'impression member to determine Whether it is related to the account it is to identify and to cause stoppage of the machine upon failure to properly compare.

Further .objects of the invention comprise the provision of electrically controlled analyzing and machine controlling, devices which automatically inhibit the presentation of a wrong impression member to the record strip upon lack of identify between the impression member and the item entry controlling devices. i

To these and other ends the invention consists in the novel features of construction, arrange- (Cl. 10i-93) ment of parts, and combination of elements hereinafterv described,V and more particularly set forth in the claims. 1

identification of data comprising, for example, a

Fig. 9 is a. diagrammatic representation of thev series ofitems with a total thereof.' These date.`

'may comprise accounts of various persons and are preferably placed upon pre-printed work: forms which constitute bills or statements of accounts rendered. Any `suitable entry receiving device may be employed for printing the variable account data upon the Work forms.

The present improvements are illustrated herein in connection with a tabulating machine of the form fully shown and described in the patent to C. D. Lake, No. 1,379,268 dated May 24, 1921. 'The particular type of machine does not enter into the present' invention `as any other form of v entry receiving device would serve the purpose of explanation and embodiment equally as well.

Referring now to Fig. 9, a stack of cards which' represent the items of the various accounts are indicated at 10 and are adapted to beadvanced by a picker 11` operated by 'an arm 12 and drawn into cooperative relationship with a. pair of feeding rollers 13. The picker feeds one card at a time to the rollers 13 which advance it during one machine cycle to the upper or control brushes 14 and during a later machine cycle to the lower or adding brushes 15. The rollers and feed mechanism are driven from a shaft 16 rotated by the usual tabulating motor and a gear train indicated generally by reference character 17. As the perforated cards are'fed to the adding brushes the.

index points are sensed in the usual manner in order that the printing type 18 (Fig. 2) may be differentially controlled. Item and total printing operations are effected by impelling the selected type vagainst the usual roller platen 19, impressions being effected upon the record strip 20 by the customary inking ribbon. listing operations a shaft 21 (Fig. 1) is operated to drive the various mechanisms.

It should further be explained that each record card carries a group of perforations representing a particular classification or group number. These perforations are sensed by brushes 14 and 15 but when a card having a new group number is presented to the brushes 14, item printing is terminated and the control mechanism more fully illustrated in the patent to C. D. Lake, No. 1,600,413, dated September 21, 1926 conditions the machine for a total taking operation. During this operation shaft 21 is idle but atotal taking shaft 22 (Fig. 1) is driven to operate various mechanisms as an incident to total printing operations.

Any suitable paper strip spacing mechanism may be provided for effecting paper spacing operations such as, for example, the type disclosed in the co-pending application of F. M. Qarroll, Serial No. 287,549, filed June 22, 1928 to which reference may be had for further details of construction and operation. The paper lstrip 20 (Fig. 1) isV drawn from a supply roll, thence passes about a tensioned roller 23, a fixed roller 24, around the platen 19 and thence between pairs of feeding rollers 24a and 24h (Fig. 3). Feeding rollers 24a are driven intermittently as an incident to item printing operations to suitably space the items as shown in Fig. 11. The paper strip 20 is, however, preferably given a greater spacing before and after total printing operations in order that the total be printed on "some predetermined line and to provide space to accommodate the variable identifying data 25 exemplified` herewith as account' names. Such printed matter identifies the data which follows below, and

which preferably comprises a series of items with a related total.

In the present instance the identifying data is printed by a member 26 (Fig. 10) which may be a printing plate of any suitable material but is exemplified herewith as a plate carrying stenclled data for printing names of accounts, and, in addition, preferably carries perforations 27 representing an arbitrary account number.

For the purpose of successively feeding the printing plates 26 which are initially stacked as shown in Fig. 3, a bar 28 (Figs. 2 and 3) slidably vmounted in a frame 29 is provided. The'bar 28 carries spring urged picker members 30, a pair of which engage the front and rear edges of the lowermost plate 26 to positively feed it from the bottom of the stack when said bar 28 is moved in one direction. Suitable spring pressed members or other means may be provided to hold the plate fed in this manner impositively on the upper surface of frame 29 while the bar 28 and picker members 30 are returned to normal position. It

During item will be obvious that when the next plate at the bottomof the stack is fed, the plate previously fed will be moved to the right (as viewed in Fig. 3) so that three cycles of operation are required to move-a plate 26 from the stack `to a gripper to be presently described.

. Under certain conditions bar 28 is automatically reciprocated as an incidentto a total taking operation by the following mechanism: Bar 28 carries a pin 31 engaging a bifurcation of alever 32 at an end distant from its connection to a rock shaft 33. Shaft 33 has secured to it an arm 34 having a pin 35 engaging a closed slot 36 of a link 37 articulated to a spring urged bell crank 38 whose roller, 39 cooperates with a cam 40 attached to a sleeve 130 which, under certain conditions is clutched to a shaft 41 driven during each total taking operation. Shaft 4l (Fig. 1) carries a bevel gear 42 meshing with a similar bevel gear 43 on a connecting shaft 44, the latter being driven by shaft 22 by a similar pair of intermeshing bevel gears 45.

Secured to a shaft 46 (Fig. 4) journalled in the side frames `47 of the attachment is an arm 48 biased by a spring 49 (Fig. 3) so that a roller carried thereby engages a profile cam 50 secured to sleeve 130. Pinned to shaft 46 is a pair of spaced arms 52 and 53 (Fig. 4) which areprovided at their ends with journal collars 5 4 which support a slidably mounted shaft 55. Splined to the shaft 55 bya key 56 is a yoke shaped plate gripper frame 57 the side arms of which carry their respective gripper arms 58 pivoted at 59 and urged towards each other by a connecting spring 60.

Pinned to shaft 55 is a pair of mushroomshaped cams 61 engaging the extensions 62 of the respective arms 58, it beingclear that as shaft 55 is shifted the free ends of arm 58 will be moved away or towards each other, and that the angular position of frame 57 is dependent on the turning of shaft 55, and furthermore, the various positions of gripper arms 58 and frame 57 may be assumed independently of each other to perform the necessary operations.

Since the shaft 46 is rocked by cam 50 it will also be clear that the position of shaft 46 alsecontrols the position of the

arms

52 and 53 and,

the parts carried thereby. I

In orderito provide for the necessary position,- ing of arms 58 by shifting shaft 55 the following mechanism is preferably employed. Attached to sleeve 130 is a cam 63 (Fig. 5) coacting with a roller carried by an arm 64. Integral with arm 64 is an armv 65 which is connected to one arm of a bell crank 67 by a twisted link 66 (see also Fig. 6). The other arm of bell crank 67 is connected tol a link 68 carrying a stud 69 (Fig. 4) engaging an annular groove of a sleeve 70 slidably mounted on shaft 46. Also slidably mounted on shaft 46 but secured to sleeve '70 is an arcuate rack member 71 meshing with a pinion 72 attached to a shaft 73. Shaft 73 is journalled in

brackets

74 and 75 secured to arm 53 and carries at the other end a similar pinion 76 meshing with a similar arcuate rack member 77 pinned to desired rocking movement f slightly in a counterclockwise direction.

83 to shaft 55 the arm 81 being confined by bracket extensions 84 of the bracket 75 engaging the sides of a collar 81a which is attached to arm 81. Attached to shaft is an arm 85a (Fig. 3) 'biased by a spring 86a actingto hold shaft 55 in a position determined by cam 78.

When the parts are in .their normal position, as shown in Fig. 3, the jaws 58 firmly grip the plate from which the next printing is to be effected. When the sleeve 130 is driven, cam 50 is almost immediately effective to rock shaft 46 to

lower arms

52 and 53 and parts carried thereby until shaft 55 occupies its lowest position, illustrated by dotted lines in Fig. 3. As the parts are thus brought to their lowest positions cam 78 is effective to rock arm 80 and through the train of mechanism previously described rock shaft 55 This will result in placing the seized printing plate di,- rectly against the record strip 20 at which time a printing impression will be effected by the following mechanism.

, Secured to a shaft (Fig. 4) journalled in the side frames 47 is a pair of downwardly extending arms 86 (Fig. 3) integrally connected at their lowermost ends by a cross piece 87 to which'is aflixed an inked felt pad 88. (See also Fig. 2.) Also secured to shaft 85 is an arm 89 (Fig. 3) connected to a cam operated bell crank 90 by a link 91. The roller 92a carried by one of the arms ofthe bell crank 90 coacts with a cam 92 secured to sleeve 130. When the plate 26 occupies the proper printing position the high part of the cam 92 is effective to rock the yoke 86-86 and inkedpad 88 against the plate and directly .over the stenciled name portion to thus produce a like impression 25 on 'the record sheet 20 which vsuitably identifies theV matter previously printed.

When the inked pad 88 has been moved reversely out of the way the cam 50 is then eective to elevate shaft 55 to the uppermost dotted line position, cam 78 being eiective during this time to rock the shaft 55 to bring the seized printing plate directly in front of the stacked plates 26 from which printings have already been effected. A continued rocking movement of shaft 55 will force the seized plate behind pairs of latching arms 93, 94 (Figs. 3 and 4) to hold the'plate in stacked position. The latching arms are secured to their respective supporting

shafts

95, 96 and are urged towards each other by a spring 97 (Fig. 5). In order to accommodate the grippers 58 the side plates 98 of the receiving chute are cut awayv at 99 as clearly shownin Figs. 1 and 5.

After the platefis in stacked position the cam zontal alignment with the plate being fed thereto.

As the record cardspcarrying group classification `are sensed by the brushes 15 the perforations are'compared vwith the group classification perforations 27 of the printing plates 26 and if the perforations completely agree further operation of the machine will ensue. Referring to the,

circuit diagram-in Fig. 9 it will be observed that current to the brushes 15 and various relays is supplied by main lines'100 and 101. From main line 100 a wire 102 leads to ay metal block 103 v tensions of v said levers.

63 (Fig. 5) is then effective to separate the grip-` pers 58 which'release their hold on the stacked carrying' brushes I5 each of which continues the circuit connection to an individual segment plate 104 through a perforation in a recordcard. The circuit then extends by a jumper connection 105 to the relay magnet 106 when a pair of reading

levers

107 and 108 are electrically bridged. AIt-4 will be apparent that the circuit connection just described is duplicated for the different denominational `orders and while the diagram shows an embodiment'for analyzing only three orders, this number may be altered to coincide with the number of denominational orders of 'the perforations 27 representing the group classification number of the printing plates 26.

Eachrelay magnet 106 when energized is adapted to close its relay contacts 109 which are in serial connection with a clutch relay magnet y 110 shunted across the main line wires 100 and 101.- Brushes 111 and 112 engage the hubs of the I reading levers 107 and 108 to provide for a cong5 tinuous electrical contact during their movements. (See also Fig. 8.)

As shown in Figs. 7 and 8 the metallic hubsy to which levers 107 or 108 are secured are mountedupon a tube of insulating material sur= rounding shaft 115. Brushes 111 or 112 as the case may be contact the associated metallic hub so that electrical contact with the hub is maintained even though the related lever 107 or 108-is rocked about shaft 115. jg

From Figs. 3, 4, and 7 it will be observed that the levers 108`for the different denominational orders are tied together for synchronous operation by a rod 113 passing through insulated ex- Rod 113 is supported at its ends by a pair of arms 114 pinned to a rock shaft 115 which carries another arm 116 (Fig. l) joined to one arm of 'a bell crank 117 by a link 117a. The other arm of bell crank lever 117 is connected to the midpoint of an arm 118 by a link 119, The arm 118 carries a roller 120 engaging a profile cam 121 attached to a stub shaft 122. This shaft, by bevel gear connections 123 and 124, is driven from the shaft 2l which, it will be recalled is rotated as an incident to each listing operation. Cam 121 is arranged to rock the rod 113 about .shaft 115 (Fig. 3.) during each item listing operation so that the levers 108 con-7 tact index point plates 125 simultaneous with the sensing of the corresponding index point perg5 apparent from Fig. 3 that as rod 113 is rocked,

springs 126 will cause levers 107 to follow the movement of levers 108 until one of the levers 107 is arrestedbythe engagement of a. reading lever 14;) 128 with one of the perforations 27'in the group Withvwhich it is in alignment as shown in Fig. '1 and as will be later described in detail. Thereupon lever 107 will be stopped and as lever 108y .arrives adjacent an index point plate 125 corre- :1.15 sponding to a perforation presented to brush 15. i levers 1 07 and 108 will be electrically bridged by onepof the plates 125 thus energizing the related lmagnet 106 which draws.` downwardly its arma-'- ture structure 129 (Fig. 3) to close related co'n- 150 Athe cam carrying sleeve rturning of the disk 131 tacts 109. As each pair of contacts 109 are closed they are latched in such position by a relatedV It will be apparent that during the first and succeeding listing operation the reading ,levers-` 128 (Fig. 3) -will be drawn over the printing plate 26 until each lever 128 engages a perforation 27. Due to the formation of the hooked end of the lever 128 the related lever 107 will be stopped in its movement when the lever 128 enters a perforation. (See Fig. 7.) Companion levers 108 continue to contact the remaining Contact plates 125 of the series but upon the return thereof they pick up and return such levers 107 that have beenA arrested by the perforations 27, levers 128 being merely cammed out of such perforations to be brought to the normal starting position. The particular plate 26 which is analyzed by reading levers 107--108 constitutes the one fed from the stack during the previous total printing operation, and although the plate is successively analyzed during each item printing or listing operation the clutch relay magnet 110 is energized during the rst listing operation if the group classification perforations in the record cards and printing plates agree in all orders. 1f the printing plate 26 does not correspond to the group classification of record cards magnet 110l will not be energized and the machine will be stopped in its operation, as will be described hereinafter.

As previously stated when the group classification of successively fed record cards changes the machine is conditioned for t-otal taking operations and in the event that the classification of the group of cards analyzed is identical to the group number represented by the perforations of the'printng plate in analyzing position, clutch magnet 110 will be energized Ato cause an operative connection ,between the driven shaft 41 and 130 (Fig. 4). Thev bevel gear 42, previously described, is secured to shaft 41 which also has secured thereto a disk 131 (Fig. 5) having a cam notch 132 in its periphery normally engaging a pawl 133 carried by a disk 134 secured to the sleeve 130. A tail of pawl 133 normallyv underlies a pin 135 carried by an upstanding arm of the armature structure 136 of relay magnet 110. i

It will -be evident from Fig. 5 that when the pin 135 is in such a position that it is over the tail of pawl 133 and the disk 131 turns clockwise in a total taking operation the cam notch 132 of disk 131 will cause the pawl 133 to be cammed out and thus disengaged from the notch 132 in the disk 131 so that disk 134 and sleeve 130 will not be rotated during such total taking operation. However, if magnetll'O should be energized under the conditions previously stated, the pin 135 will-be brought away from over the tail of pawl 133 and since the pawl 133 engages the notch 132 under action of a suitable spring, the in a clockwise direction will cause the disk 134 to be turned since pawl 133 is mounted on the disk 134. The disk 134 and sleeve 130 are therefore driven a complete revolution to perform the functions previouslydescribed.

Contacts 109 are opened to deenergize magnet 110 after the clutch .connections between

disks

134 and 131 have been established causing pin 135 to subsequently engage over the tail of pawl 133. Underlying tails of the latching levers l30a springs 109 opening vrelated contacts 141.

is a bail 137 (Fig. 3) which is connected to a bell crank lever 138 by a link 139. One arm of the bell crank lever 138 is in the plane of a pin 140a secured to a disk attached to shaft 41 so that as the pin 140a contacts the. bell crank lever the link will be rocked resulting in rocking the bail 137 and latch levers 130a, the unlatched contact under their own resiliency thus deenergizing the clutch relay magnet 110,

In order to prevent the machine from continuing its operation in the event that a wrong plate is fed,or failure of the feeding of a plat-e, the present invention contemplates .the provision of certain electrically Acontrolled precautionary devices.

As m-cre fully disclosed in the Lake Patent No. 1,379,268 the main tabulating motor is provided with an emergency or record controlled stop circuit and preferably included in this circuit are two pairs of serially connected contacts 140 and 141 (Fig. 5). Upon closure of both contacts operation of the tabulating motor may be initiated but upon opening of either pair, operation will be inhibited. The machine also includes a plate operated lever 142 the tail of which is adapted to engage the upper surface of a printing plate or matrix as it is fed, to thereby rock the lever to close contacts 140. A similar plate operated lever 144 is adapted in the same way to close its It will be observed that lever 142 engages the intermediate plate while lever 144 engages the plate fed first, or stated in other words, at the end of three total printing cycles, there will be one plate seized by grippers 58 and engaged by lever 144, an intermediate plate engaged by lever 142, and the last plate fed, in reading position and coacting with reading levers 128. To start the tabulator without any printing plates physically contacting with

levers

142 and 144 the following mechanism is provided. A pin 142@ carried by a lever 145 secured to a shaft 146 is adapted to cooperate with the longer contact plate of contacts and when urged in a counterclockwise direction is adapted to close contacts 140. A similar set of parts comprising a pin 147e carried by a lever 147 secured to a rock shaft 148 is associated with contacts 141. Closure of the contacts is,

and-147, which condition exists after a total taking operation. I

Closure of

contacts

140 and 141 by unlatching of the levers and 147 is arranged for when the first printing plate of a stack is manually fed to reading position. Y

In alignment with a pin 151 carried by the arm 32 (Fig. 5) is a shoulder 152 of an externally operable slide 153. When the slide is pushed it results in rocking shaft 33 to accomplish a feeding operation as describedheretofore to cause the bottom plate of the stack to be fed to reading position. As the slide is operated pins 154 carried fperform'ed at the printing line determined by platen 19, and the record strip being spaced an increment each listing operation. Upon a change vin group classification the machine will be conditioned fora total printing operation, which Will then ensue. If the group classification of both record cards-and the analyzed printing plate agree in all orders, relay magnet 119 will be energized, resulting in feeding the second lowest plate from the stack. 'I'he plate previously' analyzed will then occupy the intermediate position, physically contacting lever 142 to retain contacts 140 closed. After the co-operation of lever 142 with the first plate fed, a pin 160 carried by disk 131 will engage one arm of a bell crank lever 161 connected to link 155 restoring lever 145 to ineffective .latched position.

It will be observed that no plate has yet reached lever 144 so that it is ineffective to close contacts 141. Secured to shaft 41 is a pinion 162 driving a gear 163 with a two to one ratio, gear 163 vcarrying a pin 164 adapted to contact, by reason of the gear ratio selected, during the, second total printing cycle one arm of a bell crank 165 secured to link 157. Therefore, it will be apparent that since pin 164 does not operate arm 165 during the first printing cycle, that lever 14.7 wili not be latched and thus be effective to keep contacts 141 closed, permitting the machine to operate for a second tabulating operation.

'I'he machine is preferably equipped with a paper feeding mechanism that will feed the record strip a denite amount for each account printing operation thus permitting pre-printed Work forms to be used and resulting in printing of the identifying data 25 at certain lines on each Work sheet..

It should also be explained that if thenurnber of items listed does not come up to the predetermined number that may be accommodated on each Work sheet the papei strip is supplementally fed after the last item printed to provide for printing the total at a predetermined line, which is generally at the bottom of a sheet. A type of paper feeding mechanism that will provide for the above is shown fully in the co-pending application of F. M. Carroll, Serial No. 287,549, led June 22,1928

to which reference may be had for further detailsv termediate position, the first printed account on Athe record str ip 20 then occupying an intermediate position with respect to theprinting lines determined by platen 19 and inked pad 88. When the third account is printed the record strip will be advanced sumciently to permit printing by the related plate which has now been fed to the grippers' 58 and which is brought to the printinglinel during the third printing cycle.

It will be recalled that while pin 164 is ineffective to cause the restoration of lever '147 to latched position to permit contacts l141 to open at thev termination of rst total printing cycle,it is efifective during the subsequent, or second total printing cycle. At this time, howeveiga plate is in cooperation with the lever 144 causing contacts 141 to be retained in closed position, and, in fact levers 142 and 144 will keep

contacts

140 and 141 closed as long as proper plates are fed. In the event that a wrong plate is fed the next operation is prevented directly thereafter. Themanner in which this is performed is as follows:

In the event'that group classification perfora- 4tions of the printing plate and record'cardsdo not agree clutch magnet 110 Will not beenergized. The machine will, however, be conditioned for a total taking operation thus driving shaft .4 1. Pin 160, Will therefore relatchj arm 145 if itis not already in such position where it'is ineffective to keep contacts 140 closed, `and since the first plate Will remain in analyzing position, lever 142 will not be engaged by a plate to-close contacts 14u. At the termination ofthe total taking cycle, op eration of the machine will be discontinued until the proper plate is placed in position and tabulating in connection with the group of previously tabulated record cards and proper plate again resumed.

Since pin 140e is carried by a. disk attached to shaft 4l it will be effective to restore the series of contacts 109 to open position if they were closed by the agreement of perforations incertain or ders, preparatory to vbeing set up in accordance with the platev substituted foi` the Wrong one.

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 madeV by those skilled in the art Without departing from the spirit of the invention. It is the intention, therefore, to be limited only by the scope of the following claims.

I claim:

1. In a machine in which record cards containing classiiication perforations are fed ,in groups of the same classification, means for feeding the record cards, means for feeding members lid@ impression may be effected, analyzing means for comparing the classification perfor-ations of the rst record of a group with the classification per forations of an impression member, means whereby other data may be recorded from the records if an agreement is ascertained, and a supple mental data recording device for effecting an inipression from the member upon completion of the recordingof the data from the records.

2.
