The present invention relates to adding machines which print on tape the problems performed.

One object of the invention is to provide for use by shopkecpers a new and improved adding machine having a `greatly extended utility in that by virtue of featuresincorporated into the machine it also serves as a highly eiicient means for effortlessly' and rapidly printing nu; mercial price values on labels -or stickers of substantial size adapted to be placed on retail items for saler.'v

Another object is to provide a novel adding machine which is conditioned automatically by insertion into the machine of a special magazine Containing a roll of blank labels to print a single price value on each of a connected series of labels, which have an individual height greatly exceeding the vertical spacing between successive amounts tabulated on tape by the machine in performing a problem in addition.

A more specific object is to provide a dual purpose adding and label printing machine in which a capability for efficiently and rapidly printing price labels is obtained at slight additional cost, as compared to a conventional adding machine, by using structure in the machine, which provides an extended vertical spacing on tape between successive problems in addition, to provide also a desired spacing between price values printed successively on a connected series of blank labels.

Other objects and advantages will become evident from the following description 'of the exemplary form of the invention illustrated in the drawings, in which:

FIG. l is a partially sectioned perspective view of an adding and label printing machine embodying the invention; y'

FIG. 2 is a fragmentary sectional view on an enlarged scale tal/.en generally along the line 2-2 of FIG. l, and showing a standard roll of adding machine tape mounted on the machine;

FIG. 3 is a View similar to FIG. 2 but showing a blank label magazine mounted on the machine;

FIG. 4 is a sectional view taken generally along the irregular line 4 4 of FIG. 3; p

FIG. 5 shows a section of adding machine tape on which the machine has recorded as succession of problems in addition, and

FIG. 6 shows a connected series of price labels printed in the machine.

The electrically powered adding and label printing machine 10 (FIG.V l) forming the exemplary embodiment of the invention illustrated contains a complete assemblage of conventional adding machine structure capable of performing problems in additionand tabulating the problems performed yon printed tape 12 (FIGS. l and 5). Such adding machine structure is disclosed, for example, in the patents to Lippert No. 2,318,000, Mehan No. 2,486,959, and Mehan No. 2,362,709.

Successive numerical amounts or items are entered into the machine 1t) by means of a keyboard 14. After entry of an amount in the keyboard 14, the machine is run through an amount entering cycle by a conventional power operated cycling means 16,l which is operated upon depression of a moto-r bar 18. During an item entering cycle the amount set into the keyboard 14 is printed on the tape 12 by tape printing means 20, such as that disclosed in the previously mentioned Lippert Patent No. 2,318,000.

Successive amounts entered into the machine 10 and 3,632.9,615 Patented Apr. to, 1962 YFIrC-e printed on the tape 12 are normally accumulated in conventional accumulati-ng means in the machine which includes anvacc'umulating register 22, illustrated schematically' in FIGS; 2 and 3. After' all the numerical items in a problem in addition have been entered into the machine, a total is taken from the accumulator register 22 by conventional totalizing means which includes a con- Y trol 24 therefor (FIGS. 2 and r3) that is interconnected with the machine cycling means, indicated generally by the numeral 16, to run the machine through a totalizing cycle in which the printing means 20 prints the total on the tape 12 at the foot of the tabulation of the -numerical items in the problem of addition performed (FIG. 5).

The strip of printed tape 12 illustrated irl-FIG. 5 shows the tabulation of three successive problems' in addition. The totals are the numerical amounts on the tape followed by the letter "F, the T being printed by con ventionall means in the printing mechanismA 20 which is operated as ian incident to aV total taking cycle.

Again with reference to FIG. 5 it will be noted that the tabulations of successive amounts 26 added are vertically spaced by` a normal line spacing 28 which is just sufficient to acommodate vertically the numbers of one amount and provide a vnormal space vertically between successive amounts tabulated.l As will presently appear, this normal vertical spacing of successive amounts printed on the tape is provided by conventional tape advancing means (indicated generally by the numeral 38 in FIG. 2) forming a part of the printing means 20.

It will be noted further that the first printed amount of each problem in addition has a greatly extended vertical spacing 32 from the printed total of the preceding problern (FIG. 5). As shown, the extended space 32 in the lower edge of which the rst amount of a problem in addition is printed is equal to four normal line spacings 28 for printing of an amount value. This leaves three blank line spaces between the total of one problem and the lirst amount of the next problem providing a vertical separation -on the tape 12V between the tabulations of successive problems in addition. The extended spacing 32 between successive problems on the tape 12 is providedv by conventional tape extending means (indicated generally by the numeral 34- in FIG. 2) coacting with the tape advancing means 30 and forming a part of the printing means 20.

The present invention makes use of the conventional tape extending means 34 and tape advancing means 30 in an extremely simple and highly advantageous manner in adapting the machine lto print numerical price values on a connected series of blank labels or stickers 36 (FIG. 6), each of which has a height 38 greatly exceeding the normal line spacing 28 (FIG. 5) between successive amounts tabulated in a single problem in addition. Hence it is worthwhile to -describe the basic features of this structure here even though it is fully disclosed in previously mentioned Lippert Patent No. 2,318,000 to which reference may be made for a further description of details.

Thus, as shown in FIG. 2, a roll 40 of adding machine tape is fed across a shield 42 (FIGS. 2 to 4) and through a throat 44,(FIG. 3) to pass around a platen roller 46 (FIG. 4). The platen roller 46 is disposed on the upper forward portion of a rocker assembly 48 (FIG. 2) medially pivoted on a transverse shaft 49 for rocking movement in the counterclockwise direction (FIG. 2) to effect the printing of a numerical amount on the tape. This counterclockwise printing movement of the rocker assembly 48 is elected by a pair of links 50 (only one of which is shown in FIG. 2) having a lost motion pin and slot connection 52 to the lower end of the rocker assembly and operated by the oscillatable main shaft 54 form# ing a part of the machine cycling means 16.

To render the last amount printed on .the tape visible after each operating cycle of the machine, the tape is advancedfour line spaces after the amount has been printed and before the operating cycle is completed. When a series of amounts are being entered for addition, the tape is normally retracted three line spaces before an entered amount is printed-on the tape, thus providing only a single line space 28 (FIG. 5) between successive amounts tabulated in a problem in addition.

This normal retraction of the tape by three line spaces and subsequent advancement of the tape through four line spaces during each printing cycle is effected by means of a tape retracting pawl 56 and a tape advancing pawl 58 (FIGS. 2 and 3) which coact respectively with a retractingratchet wheel 60 and an advancing ratchet wheel 62 (FIG. 4) connected to the platen 46.

Both pawls 56, 58 are swingably mounted on a pivot 64 spaced from the rocker assembly pivot shaft 49 as shown in FIG. 2, and carried by a pawl advancing and retracting bell crank 66 which is also pivotally mounted on the same shaft 49 as the 4rocker assembly. The two pawls 56, 58 are spring biased counterclockwise to normal positions on the bell crank 66, which positions are determined by engagement of the rearwardly extending tails of the pawls with a sidewardly extending stop lug 68 on the bell crank.

A pin and slot connection 70 between the bell crank 66 and the link 50 enables the link 50 to swing the bell crank 66 and the pawls 56, 58 counterclockwise about the pivot 64 during the initial phase of rearward movement of the link 50 during which the pin and slot connection 52, between the link 50 and the rocker assembly 48, allows the rocker assembly to remain in its normal position. This counterclockwise movement of the arm of the bell crank 66, before the rocker assembly 48 starts to move counterclockwise, engages the tape retracting pawl 56 with the ratchet wheel 60 to rotate the platen 46 counterclockwise (FIG. 2) the equivalent of three line spaces. Thus during the ensuing counterclockwise movement of the rocker assembly effected by continued rearward movement of the link 50, the tape is properly retracted three line spaces to provide only a single line space between the amount to be printed and the amount previously printed on the tape.

After the rocker assembly 48 has moved clockwise back to its normal position, continued forward movement of the link 50 swings the bell crank 66 clockwise back toward its normal position, in the course of which the tape advancing pawl 58 operates in engagement with the pawl 62 to rotate the platen 46 clockwise the equivalent of four line spaces, making the last printed amount clearly visible as previously mentioned. This is the normal operation of the tape advancing and retracting means in printing a succession of amounts entered into the machine for addition.

Moreover, the tape retracting and advancing means operates in the same way as an incident to the printing of a total taken from the accumulator 22. However, the

Y taking of a totalY automatically activates the problem spacing means 34 (FIG. 2) which provides an extended spacing on the tape between the total of one problem and the rst amount of the next problem.

The problem spacing structure 34 comprises a tape retracting pawl shield or blocking element 72 pivotally mounted in adjacent concentric relation to the tape retracting ratchet wheel 60 as shown in FIGS. 2 and 4, and spring-biased clockwise to the normal position shown in FIG. 2 in which the shield 72 is out of the path of the retracting pawl 56. As an incident to operation of the machine through a total taking cycle, the shield 72 is swung counterclockwise into a retracting pawl blocking position, shown in FIG. 3, and latched in this position until it is released during the next amount entering cycle ofthe machine. v

' The shield 72 is shifted counterclockwise from its inoperative position (FIG. 2) to its operative position (FIG. 3) by clockwise movement of a latching pawl 74 (FIG. 3) medially pivoted on the rocker assembly 4S and having a forward end underlying the shield 72 as shown. The shield 72 is retained in this operative position (FIG. 3) by engagement of the latching pawl 74 in a notch 76 in the shield which also holds the pawl against counterclockwise movement by a spring 77 connected to the forward end of the pawl. Y

The latching pawl 74 is swung clockwise `during a total taking cycle by engagement of a stud 78 on the rear end of the latching pawl with the rear end of a slide 80 which is moved downwardly during counterclockwise movement of the rocker assembly 48. The medial portion'of the slide 80 is slidably mounted on a pin 82 on the rocker assembly 48 that moves downwardly during counterclockwise movement of the rocker assembly. The forward end of `the slide 80 connects with a pivot 83 carried by the lower end of the totalizing control lever 24 which is medially supported on a pivot 84 above the pivot 83. Thus counterclockwise movement of the rocker assembly 48 swings the slide 80 clockwise.

During a normal amount entering cycle when the totalizing lever 24 and pivot 83 are in the neutral position shown in FIG. 2, the relation of the pivot 83 to the pivot 82 is such that the clockwise movement of the slide 80 during the operating cycle is not suflicient to move the latching lever stud 78 downwardly to the extent necessary toy latch the forward end of this lever into the retracting dog shield notch 76 (FIG. 3). Consequently, during a normal item entering cycle the shield72 swings counterclockwise momentarily and then returns to its normal position. Since this movement of the shield occurs during the counterclockwise movement of the rocker 48 which is subsequent to the counterclockwise movement of the arm 66, it does not interfere normally with operation of the pawl 56 to retract the tape.

To take a total, the control v24 is moved counterclockwise as indicated by the arrow 86 in FIG. 2. This moves the slide pivot 83 rearwardly in relation to the pin 82, thus serving to increase the clockwise movement of the slide 80 during the totalizing cycle to the extent that the latching pawl 74 swings up into the shield notch 76 and retains it in shielding position, as shown in FIG. 3. Thus the retracting pawl blocking shield 72 is retained in its effective position after completion of the totalizing cycle.

During the next item entering cycle, engagement of the tape retracting pawl 56 with the ratchet wheel 68 is blocked by the shield 72, thus preventing the normal three line retraction of the tape. The ensuing advancement of the tape through four line spaces after printing of the item entered provides the previously mentioned extended space 32. between successive problems in addition las shown in FIG. 5.

A normal item entering cycle following a totalizing cycle also releases the shield 72 fromV its operative position for spring return to its normal position (FIG. 2),

vThis is effected by a shield release pawl 86 pivotally mounted on the rocker arm stud 64 and spring biased counterclockwise to the normal position shown in FIG. 2.. Near the end of counterclockwise movement of the crank 66 in the course of an item entering cycle following a totalizing cycle, a forward end of the shield release pawll 86 engages the shield 72 in its operative position (FIG. 3) shifting it somewhat counterclockwise about its axis to release the latching pawl 74 from the shield notch 76. Both the latching pawl i4 and the shield 72 return to nor-v mal position at the conclusion of the cycle. The shield remains ineffective until the machine again goes through a totalizing cycle.

It is also noteworthy that counterclockwise movement ofthe control 24 to initiate a totalizing cycle shifts the slide 80 rearwardly, causing the rear end of the slide to engage the shield release pawl 86 and hold it clockwise to the shield from operative position.

Since all this structure is conventional and' is already present in adding machines used by shopkeepers, its inclusion in the machine embodying applicants invention does not increase the cost of the machine over` that of conventional machines already in use.

At only nominal additional cost', the machine 10 is' so constructed that it is conditioned automatically upon' the insertion into the machine of a special magazine 90' containing a blank roll' of perforated' labels to print a single numerical price on' the successive labels even though they have a height greater than a single line spacing 28 (FIG. 5) between successive tabulated amounts of a. problemin addition, For this purpose very simple means is provided to activate the'v previously describedl problem 'spacing means 34 (FIGl 2) in the machine as vvan incident' to mounting of the special magazine 90 on the machine and to maintain this problem spacing mechanism contimiously effective so long as the magazine remains on the machine.

Thus, as shown in FIGS. 2 and 4, a transverse bail" 92 is pivotally mounted in theA rocker assembly14v83 inonderlying relation to the paper throat 44 as shown in FIG. One end ofthevk bail 92 is non-rotatably ixed tol the previ'- ouslymentioned l'atching pawl 'I4 fory the retractin'g' pawl shield 72` and serves the medial pivotal support for the latching pawl. The medial portion ofthe baili 9'2y is horizontally offset rearwardly as shown in FIGS. 2 to 4, to underlie the previously mentioned shield 42 onthe' rocker assembly 48 which extends rearwardlyy and downwardly from the tape throat 44. 'A i Thev medial odset portion 9'4 (FIG. 3') of the bail 92 is exposed rearwardly and upwardly (FIG. 4) through one of a pair of openings 98, 109 in the shield 42;

kThe special magazine 90 adapted to contain a'- rol-l 102 (FIG. 4)V of blank labels is designed' -to engage the offset bail portion 94 to move it downwardlyv and forwardly (FIG. 3) to swing the bail 92 clockwise (FIG. 3) auto'- matically as an incident to mounting of the magazine on a special cradle 104 secured to. the rear of` theA machine as shown in FIGS. 3aV and 4.

In the preferred construction shown,y thev cradle 1104 comprises a pair of laterally spaced support plates 106, 108 projecting upwardly from a horizontal base 1150l and defining at the upper rear corners of the respective plates an aligned pair of notches 112, 114 adapted to receive opposite ends ot a removable support spindle 1'16 for a roll of regular adding machine tape 40 (FIG. 2) which is mounted on the machine as describedwh'enthe machine is to oe usedy as an adding machine.

The label magazine 90, which is substituted in place of the tape roll 40, also has a support spindle 118 (FIGS. 3 and 4) opposite ends of which are adapted 'tol tit' into the support plate notches 112 114. The rolll `102 off blank labels is supported on the magazine spindle 11S' between two parallel plates 120, 122' mounted on the spindle 11S in lixed spaced relation to each other in predetermined positions along the axis of the spindle to provide proper alignment of the label rollI 162 with denominational orders of the machine beginning from the right, as will be more clearly described presently.

As shown, the plate 12h' is secured to the spindle 118 byv a boss 124i clamped tothe spindle by a set screw 126 which provides for adjustment of the plate 120 along: the spindle. The other plate 122 is removably supported' on the spindle 11S by a boss 128 and secured to the plate 120 in spaced' relation to the latter by a stud 130 in the plate 120 which snaps into` a notchl 132l (FIG. 3)' in the plate 122.

The upper forward portion of the" respective plates 120, 122, with reference to FIG. 3, define a pair of forwardly and downwardly extending projections 134,` 13.6. which, upon mounting of themagazine'inthe cradle 1:04, project through the respective shield openings 9S, 100 as shown. The projection 134'l engages the offset bail portion 94 t'o pivot the' bail 92 and the shield'latching pawl 74 counterclockwise as described.

The sp'ring'4 76 (FIG. 3) connected tothe latching pawl 74 continues to urge the pawl 74y and bail 92 counterclockwise' against the' projection 134, thus tending to force the projection 1.34 rearwardly and upwardly. Tosus'tain this' reaction, the rear edges of the respective cradle plate notches 112, 114 are shaped to form forwardly open hooks 1381, 140 which receive trunni'ons' 142, 144 of re'- duced diameter on the respective extreme ends of the magazine spindle 118. y

The magazine is held against rotation andu'rged upwardly and*rearwardlyV to seat the' trunnions 142, 144 in the hooks 138, by` a bail 146 pivoted to the lower rear portionsof the respective `cradle plates 0106, 108, as shown, and' urged clockwise (FIG. 3)' by springs 148. A cross" bar 150011 the upper forward'portion of they bail 146 extends through slots 152 in the cradle side plates and nts into a pair of downwardly open notches 154 in the respeerive magazin-e plates' 120, 122'. The yieidabnity of the bail 146 facilitates'mounting. and removal of the magazine 90. y i v Y As shown in FIG. 6, the successive labels' 36 supplied in the roll 102 (FIG. 4) join each other in a continuous series. However, jluncture's of adjacent labels are perforated, as' indicated by the numeral 156, and notched at opposite sides' as indicated by the numeral 158. 'I'he labels 36shown` have a width sufficient to accommodate price markings of four significant figures and have an individual' height only slightlyv less' than the label width. The labels' are coated on the back with a pressure sensitive adhesive and are secured to a coated paper strip 160 slightly wider than' thev series of labels, or they may be gummed labels. y

y The spacing of the magazine plates 12o, 122 is just sufi'cient' to accommodate the length ofthe roll of labels 102as" determinedv by the width of the strip 160 wound in the label roll. The transverse positions of the magazine plates'1l20, 122 as determined by the spindle 118 in the cradle 104 properly locates the labels 1564 in alignment with the four lowest denominationalv orders of the printing means 20 (FIGS. 2 and' 3). of thev machine.

The blank labels are threaded. through the throat 44 t (FIG. 3) andj into the printing mechanism 20 in the same manner as adding machine tape.

The clockwise' shifting movement of the bail 92 from the position shown in FIG. 2 to the position shown in FIG. 4` effected by a mounting of the'V label magazine 90 on the machine as described swings the latching pawl 74 for the retracting pawl disabling shield 72 into the position shown in FIG. 3. Clockwise movement of the latching pawl 74 from the position of FIG. 2 to the position of FIG. 3 swings the shield 72 from its inoperative position (FIG. 2) to its fully operated position (FIG. 3) in which itis held by the latching pawl 74. Since the latchin-g pawlA 74 is held continuously in the position shown in FIG. 3 so long as the label magazine 90 is installed on the machine, the shield 72 is also held continuously in its operativel position.

Thus when the machine is run through an item entering. cycle in which the shield releasing pawl 86 (FIG. 2) engages the shield 72 in its operative position (FIG. 3) and` moves the shieldl somewhat counterclockwise (an action which would normally release the latching pawl 74 for counterclockwise movement which would release the shield) the latching pawl 74 is held in its latchingposition byv thebail 92 and continues to' retain the shield in its operative position in which it blocks engagement of the tape retracting pawl 56.

As a consequence, the's'eries of blank' labels 36 fed into the printing mechanism are not retracted during a printing cycle', andi accordingly are advancedlthe equivalent of four line' spaces' during each printing cycle'. Hence, the machine will function automatically upon operation of the motor bar 18 when the magazine' 90` is' installed in -the machinet`o print a single price value oni each off the label blanks 36, even though the individual labels have a height approximating four line spaces. To print a succession of price labels of the same price value, the price is set into the keyboard 14 and the repeat key 162 (FIG. l) set. The motor bar 18 is then depressed and held down while the machine operates through a continuous series of item entering cycles which print price values on the desired number of labels. Then another price value can be entered into the keyboard 14 and the procedure repeated to produce labels for a different item.

The shopkeeper has then only to remove the printed labels from the backing strip 60` and apply them to the individual items to be sold.

While I have shown a preferred embodiment of my invention, it will be apparent that variations and modifications thereof maybe made without departing from the underlying principles and scope of the invention.
