Fig. 1 diagrammatically shows how the inventory cards are fed through a tabulator of the Powers type to print lists in accordance with the perforations in the cards; which lists may be checked against the copy of the order and the invoice to guard against any possible errors which may occur in the punching operation.

Fig. 2 shows in detail the merchandise display card 10 which is both printed and punched with the store department number, the sales price, the serial number, the size, the color, and the classification of the article. The merchandise card is slightly indented along the line X to weaken the same so that the upper portion of the card containing the hole I2 may be detached from the lower portion containing the punched information. The hole 12 is used for fastening the card by means of a string to the article to be sold. The merchandise display card is divided into ten horizontal rows numbered .to 9 con- Fig. 3 shows an inventory card for an article .of merchandise. This card is single punched simultaneously with the merchandise display card and is filed in the inventory file when the article is sent to the sales floor.

Fig. 4 shows a chart by means of which the double code perforations in the display card may be translated to correspond to a portion of the single punchings on the inventory card.

Fig. 5 shows the circuit arrangements, magnets and relays for controlling the perforating machine which single punches the inventory cards.

Fig. 6 shows the circuit arrangements, magnets, and relays for controlling the perforating machine which double punches the merchandise display cards. The two machines are mechanically similar to the perforating machine disclosed in Patent No. 1,305,557, issued June 3',- 1919, to W. W. Lasker. However, in the present invention electric circuits have been designed to elecsecutively from bottom to top, and into ten vertical columns numbered 1 to 10 consecutively from left to right. The dot-dash line Y divides the card into upper and lower sections so that each vertical column has an upper and a lower field in which the coded perforations corresponding to numerals may be made.

Fig. 3 shows in detail an inventory card which is provided for each article purchased by the department store. Each inventory card is divided into forty-five vertical columns numbered 1 to 45, consecutively, from left to right, and is divided into ten horizontal rows numbered 0 to 9 consecutively from top to bottom. This card is divided into fields for designating certain information when perforated therein. For instance, the first field comprising

vertical columns

1, 2, and 3 designates the month and day the article was purchased, the second

fleld including columns

4, 5, 6,

and 7 designates the department store number of the order, the third

field including columns

8, 9, 10, and II designates the code number of the manufacturer to whom the order was sent, the fourth

field including columns

12, 13, and 14 designates in coded form the date received by month and season so that at a later date the store manager or buyer is enabled to find out how long the article has been on the sales fioor and whether the article is in season. The fifth

field comprising columns

15, 16 and 17 is for use when the price of an article has been marked down for special sale or other cause, the column 15 indicating the number of times the article has been marked down and

columns

16 and 17, the.

reason why such article is marked down. In a similar manner the remaining columns are divided into fields as shown by heavy lines to designate the department number, classification of article, the cost price, the sales price, the serial number, the size, the color, the kind of material, and the style of the article.

The inventory card H is single punched with a single perforation in each vertical column to designate numerals corresponding to certain data dependent upon the fields in which the perforations appear. In order that the merchandise card be punched with the same information as the inventory card, it is necessary that each vertical column in the merchandise card have perforations therein which will correspond to two numerals instead of one numeral because of the limited space on the merchandise card. Each vertical column of the merchandise card is therefore divided into two sections, an upper section or field and a lower section or field. Since each field of each vertical column has perforation spaces less in number than the number of numerals which are to be designated, the various numerals are represented in code, that is, each numeral is represented by two perforations. Successive numerals in the merchandise card are designated by combination perforations .in the upper and then the lower fields of each successive vertical column. The code for perforating the merchandisecard is clearly shown in Fig. 4.

Referring now to Figs. 7 and 8, the mechanical operation of the two punching machines is preferably the same as disclosed in United States Letters Patent, No. 1,305,557, to which reference can be had for details not here deemed necessary to described. Generally the feeding means for f the card: may be any suitable construction for successively removing the cards one at a time from a stack and delivering them to feed rollers Hi. The cards are delivered to the rollers HI the card because these by a block which is operated in timed relation to the cycle of operations by means of connection with the main shaft I85. The cards delivered from the card magazine enter a passage I24 of the punching unit II I and abut an automatically operated stop which locates the card punching positions in position respectively with punches 126 on one side and holes 121 in a die 128 on the other side. The punches 126 are guided at their lower ends by a plate I30 which moves with the die 12! and the arrangement is such that when the card engages, with the punches which are not set such punches will be pressed back by the card and die without making perforations, while the punches which have been set will perforate punches are locked in operated position.

The perforating selecting means or set-up bars III are slidably mounted in a fixed frame 132, each being notched to form a cam acting latch 133 which, upon movement of the bar 13!, shifts a laterally movable latch plate 734 so that any selected set up bar "I will be held down and locked during the punching operation. Below the set up frame 132 is a cage 134' holding a plurality of slidable punch engaging pins 135, the number corresponding to the number of set-bars Ill andthe arrangement being such that each pin 135 is in alinement with a set-bar 13] at its upper end and with a punch (26 at its lower end. The pins 135 are respectively held projected into engagement with the set-bars "I by springs 135 so that each is automatically returned to normal position, with its lower end spaced from its punch,

and also returns its bar "I when the latter is released after the punching operation. The punches 128 are similarly arranged and correspond to the number and arrangement of the setbars Ill so that whenever a pin 135 is held locked and projected into engagement with its punch head that particular punch will be rigidly held against movement imparted by the die (28.

The selection and setting of the perforating selecting means or set-up bars 13! is accomplished by a carriage 131, which is arranged to travel by a step-by-stepmovement to successive rows or groups of set-up bars 13!. This carriage is provided with a plurality of spring pressed plungers 138 corresponding in arrangement and number to a record column of the inventory card,

which in the preferred form is made up of twelve record positions representing numbers. Associated with each plunger 138 is a flexible rod extending to a solenoid magnet and arranged so that the energization of the solenoid magnet moves the rod to cause the operation of its associ ated plunger 138. In the first machine there is provided a key, such as key N12, for each solenoid magnet, such as magnet I22 while the magnets of the second machine are controlled by the same keys and relays such as relays 230 to 238, inclusive, and relays Hi to I50, inclusive, as will be more fully described hereinafter.

In the operation of the punching unit, the carriage I31 travels longitudinally step-by-step across the rows of set-up bars "I stopping momentarily over each row so that the actuation of any of its plungers 138 will cause a set-up bar "I to project its pin 135 into the path of the -alined punch 126. In the present invention the carriage one step responsive to two actuations of a key or keys because only the second actuation of a key operates the magnets, as will be more fully explained hereinafter.

When the complete set-up is made, the trip key TR is depressed to control the actuation of the machine so that the die 128 rises to bring the card into punching relation with the punches and those which are rigidly held by the set pins 135 are caused to perforate the card. The reciprocation of the die 128 takes place in timed relation with the rotation of the shaft I85 after which the cards are moved out of the punching machines into their card hoppers in a well known manner.

Having described the system and the apparatus.

to be used, a detailed description will now be given of the operations necessary to punch the inventory and merchandise cards.

The punch operator, upon receiving a copy of a merchandise order, will first close the knife switch I98 to start the motors I91 and 291 of the respective punches shown in Figs. and 6. The punch operator now operates the keys of the key board in accordance with the data on the merchandise order. The operator, therefore, operates key I03 and then key IOI twice in order to punch the inventory card II (Fig. 3) in

vertical columns

1, 2, and 3 with the date of purchase. Responsive to the operation of key I03 a circuit may be traced as follows for energizing the punch magnet I23: From ground by way of repeat switch spring I8I and its resting contact, key I03, magnet I23, conductor I00, terminal I18, and battery at lever I16. Relay I43 energizes in parallel with magnet I23 and at armatures I51 and I58 connects the common conductor IIG to conductors MI and 205. The closure of these contacts are without effect at this time because the control springs I12 are not closed in this position of the punch carriage. Magnet I23, upon energizing, sets the perforating means or pins of the punch so as to punch the inventory card in horizontal row 3 in vertical column 1. When the key I03 is released, relay I43 and magnet I23 deenergize. The deenergization of the magnet causes the carriage, due to its escapement mechanism, to move one step so that the carriage is in position to set the next row of perforating means to punch the inventory card in the second vertical column. Responsive to the operation of key IOI relay HI and punch magnet I2I energize from ground at spring "I over conductor I00 and battery at lever I16; Relay I at armatures I53 and I54 connects the common conductor II6 to conductor 20I and conductor 203. This operation, at this time, is also ineffective. because the common conductor H6 is not connected to the common grounded conductor 200. Magnet I2I operates and sets the perforating means to punch the inventory card in horizontal row 1 in vertical col umn 2 and upon the release of key IOI the magnet and relay release; and the magnet, in the well known manner, causes the carriage to take another step. The same operation just explained takes place responsive to the second actuation of the key I 0 I. The perforating means of the punch is now set to punch the inventory card in accordance with the date of the purchase of the merchandise, which in this case, is the third month or March and the eleventh day of the third month.

The operator again refers to the copy of the order and now operates the keys in accordance with the number of the order, which in this case is order No. 2345. The operator accordingly op- ,erates the keys I02, I03, I04, and I05, thereby causing the punch magnets I22, I23, I24, and I25 in the order named to set the perforating means to punch the inventory card in vertical columns 5 4, 5, 6, and '1 in

horizontal rows

2, 3, 4, and 5, respectively. Relays I42 to I45, inclusive, also energize in parallel with the punch magnets but their operations are ineffective because the control springs I12 are still open. Responsive to the operation of the magnets the carriage of the punch has been stepped to position 8 ready to set the next row of perforating means to punch the inventory card in vertical column 8. In a similar manner the operator again refers to the copy of the order and operates the keys in accordance with the code number of the manufacturer to whom the order was sent, or in this case No. 4321. Responsive to this operation the perforating means is set to punch the inventory card II in

columns

8, 9, 10 and 11 as illustrated in Fig. 3. In case the merchandise on the above-mentioned order has not been received at the time that the operator is punching the cards, the

vertical columns

12, 13, and 14 are left blank, or in other skip magnet is operated to operate the escapement of the carriage to take one step for each actuation thereof in a well known manner. In a similar manner the operator operates the skip key to cause the carriage to' move to position I1.

When the carriage of the punch (Fig. 5) reaches its seventeenth position the control bar I1I has been moved to the right a sufiicient distance to close the control springs I12. The closure of the control springs I12 connects the grounded conductor 200 to the common conductor II6 so that" 40 the operation of the relays such as relay I are effective to now close operating circuits over the conductors 20I to 205, inclusive.

The operator now operates the keys IIO, I02,

lol, and H0 in succession in the order named in. 4:,

order to punch both the merchandise tag or card I0 and the inventory card II with the mark-down reason number, if any, the department number for which the merchandise or goods was purchased, and in accordance with the classification 50 of the article bought. Responsive to the operation of key I I0, magnet I30 and relay I50 are energized by way of the grounded conductor 200. Magnet I30 operates and sets the" perforating means to punch the inventory card in horizontal row "0 vertical column 17 to indicate that this arti le has not been marked down. Relay I50, upo energizing, at armatures I5I and- I52 closes circuits for energizing relays 230 and 23I (Fig. 6) as follows: from grounded conductor 200, through control springs I12 which are now closed, conductor I I0 and thence by way of armatures I5I and I52 over conductor 20I and conductor 202 and

armatures

252 and 253 and their resting contacts to relay 230 and relay 23I to battery. Relays 230 and 23I, upon energizing, at

armatures

230 and 2 complete locking circuits for themselves in series with relay 238 and grounded armature 249 and at

armatures

240 and 242 prepare circuits for operating

magnets

229 and 228. Relay 238 does not immediately energize in series with relays 230 and 23I because relay 238 is short circuited from the ground connected to conductor I I6. When the operator releases the key IIO magnet I30 and relay I50 deenergize. -Responsive to the deenergization of magnet I20 the carriage of the first machine (Fig. is stepped to the next position or position I3 and the relay I50, upon deenergizing, at armatures I5I and I52 removes ground from conductors I and 232, thereby removing the short circuit around relay 233, whereupon the latter relay energizes in series with the locking circuits of relays 220 and 23I. Relay 223, upon energizing, at

armatures

252, 252, 254, 255, and 255 transfers the conductors "I, 202, 202, 234, and 235 from

relays

223, 22I, 222, 222, and 224 to magnets 224,222, 222, 22I,and 223, respectively. At armature 251 relay 223 prepares a circuit for relay 235 and a locking circuit for relay 225.

Responsive to the operation of key I02, magnet I22 and relay I42 energize over the grounded conductor 200. Magnet I22 prepares the perforating means of the first machine to punch the inventory card in horizontal row 2 in vertical column I3 and relay I42 at armatures I55 and I55 grounds conductors 20I and 204 by way of conductor H5 and control springs I12. Responsive to the grounding of conductors 20I and 234, circuits may be traced for energizing magnet 224 and magnet 22I in series with relay 221 as follows: from grounded conductor 20! armature 252 and its working contact, magnet 224, winding of relay 221, terminal 210, and battery on lever 215; and from grounded conductor 204 by way of armature 255 and its working contact, magnet HI, and winding of relay 221 to battery at terminal 213 as previously traced. Relay 231, upon energizing, at armature 25I closes a circuit for energizing relay 226 and

magnets

223 and 223. These magnets are operated practically simultaneously with magnets 224 and HI. Responsive to the operation of

magnets

22I, 224, 223 and 229 the perforating means of the punch shown in Fig. 6 is set to punch the merchandise card in horizontal rows I, 4, 3, and 9 in vertical column I as indicated in Fig. 2. Relay 235, upon energizing, at armature 250 closes a locking circuit for itself in series with relay 235 by way of grounded armature 251 of the transfer relay 223. Relay 235 does not immediately energize because the same is short circuited from ground by way of armatures 25I and 251. When the operator releases the key I02 the magnet I22 and relay I42 deenergize. The deenergization of punch magnet I22 steps the carriage in the same manner as previously explained and the deenergization of relay I42 removes ground from conductors 20I and 234, thereby opening the circuits of magnets 224 and HI and relay 231. Relay 221, upon deenergizing, at armature 25I-removes the short circuit from around relay 235 and also opens the circuits of

magnets

229 and 228, thereby causing such magnets to deenergize. Responsive to the deenergization of magnets 22!, 223, 224 and Hi the carriage of the punch shown in Fig. 6 is permitted, due to its escapement, to take one step. when the short circuit around relay 235 is removed at armature 25I, relay 225 energizes in series with the locking circuit of relay 225. At armature 243 relay 225 opens the circuit of relays 223, 220, and NI, whereupon said relays denerglze. At armature 251 transfer relay 223 opens the circuit of

relays

235 and 225, whereupon such relays deenergize. At armatures 252 to 256, inclusive, transfer relay 233 transfers the conductors 23I to 235, inclusive, back into engagement with relays 223 to 224, inclusive. The relays and magnets of the punch shown in Fig. 6 are now in normal position ready for the next operation while aoaaess the carriage has been moved to position 2 in readiness to set the next row of perforating means to punch in the second vertical column of the merchandise card I0.

Responsive to the operation of key IOI magnet I2I and relay I4I energize from grounded conductor 200. Magnet I2I causes the perforating means to be set to punch the inventory card in horizontal row I in vertical column I9, and relay I4I at armatures I52 and I54 grounds conductors 20I and 203. Responsive to the grounding of conductors 20I and 202

relays

230 and 232 energize over a circuit similar to that previously traced for relays 230 and 22I. At

armatures

240 and 244

relays

230 and 222 prepare operating circuits for magnets 220 and 221 and at armatures 220 and 242

relays

230 and 232 close locking circuits for themselves in series with transfer relay 233. Transfer relay 225 does not immediately energize because it is short circuited by ground extending over conductors 20I and 203. When key MI is released the magnet I2I is deenergized to permit the carriage to move one step andrelay I at armature I54 and armature I54 removes ground from conductors 20I and 202 thereby removing the short circuit from around transfer relay 223 and permitting such relay to energize in series with the locking circuits of

relays

223 and 222. Transfer relay 223 at armatures 252 to 253, inclusive, again transfers the leads 20I to 203, inclusive, from the relays direct to the magnets so that the next operation of a key in Fig. 5 operates the magnets direct instead of the relays. Responsive to the operation of key III magnet I23 is operated to prepare the perforating means to punch the inventory cards in the zero horizontal row in vertical column 20 and relay I50 is energized to ground conductors 20I and 202 at armatures I5I and I52. The

magnets

224 and 223 and relay 231 energize by way of grounded conductors 20I and 202 to battery at terminal 213. At armature 25I relay 221 closes the circuit for operating magnets 229 and 221 and also closes the circuit for energizing relay 226. The punch magnets 22!, 221, 224, and 223 energize and set the perforating means of the punch in Fig. 6 to punch the merchandise card in vertical column 2 as indicated in Fig. 2. When the operator releases the key IIO magnet I30 deenergizes, thereby causing the carriage of the punch in Fig. 5 to operate one step and relay I50 to remove ground from conductors 20I and 202 at armatures I5I and I 52. When ground is removed from conductors 20I and 202

magnets

224 and 223 and relay 221 deenergize. At armature 25I relay 221 opens the circuits of magnets 228 and 221 thereby permitting all of the magnets to release and step the carriage of the punch in Fig. 6 toits next position or in a position corresponding to the third vertical column of the merchandise card. At armature 25I relay 221 again removes the short circuit from around relay 235, thereby permitting such relay to energize in series with the locking circuit of relay 235. Relay 225, upon energizing, at armature 249 opens the circuit of transfer relay 220 and

relays

230 and 222, thereby permitting such relays to deenergize and return their various armatures to normal position. The circuits of relays 225 and 236 are opened at armature 251 by the deenergization of relay 223. All of the apparatus in Fig. 6 is now in normal position with the exception of the carriage which is now in position 2. When the carriage of the punch shown in Fig. 5 moves into position 2i the control bar I" opens the control springs I12 so that the relays in Fig. 5 do not control the punch in Fig. 6 while the punch in Fig. 5 is punching in columns 2|, 22, .23, 24, and 25. By the operation of the proper keys the cost price of the article by the punch in Fig. 5 is set in the proper rows of the perforating means in an obvious manner and it is thought that this operation need not be explained because it is the same as heretofore described. When the carriage of the punch shown in Fig. 5 reaches its twenty-sixth position the control bar I1I agrin closes the control springs I12 so that the relays in Fig. 5 may control the punch in Fig. 6.

The operator now operates the keys in accordance with the sales price and the punch in Fig. 5

and the punch in Fig. 6 are operated in a manner similar to that described to prepare the perforating means to punch the inventory card I I and the merchandise card I as shown in Figs. 2 and 3. Since the operation of the two punches is practically similar to that previously described, it is believed that further explanation is deemed unnecessary when it is understood that the punch in Fig. 6 is only controlled during the time that the control bar I1I closes the control springs I12. It will be noted that the punch in Fig. 6 stores the first digit on the relays such as relays 230 to 234 while the punch in Fig. 5 is setting the perforating means responsive to the first operation of a key and that when a second key is operated the punch in Fig. 5 sets the perforating means of the next or second set and this time causes circuits to be closed to Fig. 6 so that four magnets (two of which have been previously prepared by the storing relays) are operated to set the perforating means of one row or set to punch the merchandise card with four perforations in a single vertical column. By remembering that the magnets in Fig. 6 punch holes in horizontal rows in accordance with the last digits of their reference characters it can be plainly seen by consulting the chart in Fig. 4 that the merchandise card shown in Fig. 2 will be punched in the manner as indicated in Fig. 2 responsive to the operation of the proper keys. After completely setting the various sets of perforating means the operator will operate the trip key TR, thereby closing a circuit for energizing relay I19 as follows: from grounded conductor 200, trip springs TR, relay I19, conductor I00, and terminal I18 to battery. Trip relay I19, upon energizing, at armature I80 permits the tensioned spring I92 to rotate the flange I94 into engagement with the rotating flange I95 by operating armature I80 out of the path of the pin I 93. The spring I92 turns the flange I94 upon its threads so that flange I94 engages the rotating flange I95 thereby causing the shaft I85, the interrupter I84 and flange I90 to rotate with the shaft I96 The rotation of shaft I85 causes the card to be perforated in accordance with the pins or perforating means which have been set and locked responsive to the operation of the magnets as previously described. After the cards have been punched the. operator may operate the carriage return key CR, or in case she does not, the interrupter I84 will be rotated so as to complete a circuit between springs I82 and I83, for the purpose of energizing the carrlage return relay. In either case relay I13 is energized from grounded conductor 209 by way of the carriage return springs CR, or springs I 82 and I83, to the winding of relay I13 and battery. By the operatio'n'of armature I14 relay I13 permits the lever I16 to be operated by spring tension so that the battery connected tolever I16 is disengaged from terminal I18 and is connected to terminal I11. Due to this operation a circuit may be traced from ground at wiper I88, through the copper band on the magnetic clutch and through the winding of the magnetic clutch to the copper band, which is engaged by wiper I86, terminal I11 and battery on lever I16. Due to the energization of the winding of, the magnetic clutch the magnetic clutch I89 is magnetically held in engagement with the rotating disc I90 thereby causing the clutch to wind up the tape I81 to cause the carriage of the punch to be returned to its normal position. The return of the carriage to normal position causes all of the pins which have been locked in operated position to be returned to their normal position in a manner similar to that described in the Patent No. 1,643,779, ,issued September 27, 1927, to W. W. Lasker. When the carriage return relay I13 operated its armature I14 lever I16 opened the circuit of trip relay I19, thereby permitting the latter relay to drop its armature I80 in the path of the rotating pin I93. When the carriage of the punch shown in Fig. 5 has been returned to its normal position, arm I15 strikes the lever I16 to cause it to disengage from terminal I11 and engage with terminal I18. At this time the wipers I82 and I83 of the interrupter no longer complete the circuit for relay I13 and therefore armature I14 is allowed to drop in position to hold the lever I16 in the position shown in the drawings until relay I13 is again actuated. By the disengagement of the lever I16 from terminal I11 the circuit through the winding of the magnetic clutch is opened and the carriage remains in normal or its home position until again actuated by its escapement. The two shafts I85.and

normal position and may now be used for punching a different inventory card it being understood that a new card has been positioned in punching position in the manner described in the aforesaid Lasker patent.

The operation of the trip key TB in addition to closing a circuit for the trip relay I19 also closes a circuit over conductor 206 to the trip magnet 219 inFig. 6. The carriage return relay 213 is also operated over

conductors

200 and 201 in a manner similar to the operation of carriage return relay I13 and it is believed that it can be readily seen that the carriage of the punch shown in Fig. 6 is returned to its normal position in a manner similar to that described for the punch carried in Fig. 5.
