application October :4 claims. (ci. 1644113) This invention concerns punching machines and relates particularly to devices provided to permit punching of cards to represent serial numbers.

F At times it is desirable to have such serial numing operations successively, column by column.

A still further object is to provide for selective controlling connections between the elements which represent serial numbers and a plurality of sets of punching devices and to provide further selective connections so that the selected set of punches may be correlated with any of the card columns of the selected cardl field comprising a predetermined number of columns.

By the last named arrangementany card eld may be selected to receive serial numbering, and anyselected columns may' receive thepunching', punching being preferably etfected in the selected columns, in a step by step manner.

Further and relatively important objects will be evident as the arrangement is understood, disclosed in detail in the accompanying drawings in which:

Figs. 1 and 2 taken together represent a longitudinal sectional view of the assembled punching machine.

Fig. 3 is a top plan view of part of the machine shown in Figs. l and 2.

Fig. 4 is a view similar to a part of Fig. 3 disclosing certain parts in different positions.

i Fig. 6 is a view in side elevation of the consecutive numbering control device.

Fig. 7 is a plan view taken on the line 7-7 of Fig. 6. l

Fig. 8 is a perspective view of a portion of the consecutive numbering control device.

Many of the detalls of the machine are not disclosed in this application as they are shown in detail in the Patent .it 1,950,476 dated March 13, 1934 maturing from application Serial No. 355,155,

med April 15, 111m), of winch uns application 1s s division. For a more complete understanding of the parts only generally mentioned or described herein, reference to the patent mentioned should be made. However, as much of the complete machine will be described herein as is necessary for ,I

an understanding of the present invention.

As explained in the patent, the machine be conditioned so that a series of cards in a card hopper 57 which are to be punched with the serial numbers are successively fed between a pair of feeding rollers'70 (Fig. 2) which feed them to the punching section B (Fig. 1). The cards in transit are then intermittently stepped for a punching operation and then fed by rollers 160 to an analyzing section A and then discharged by rollers 165. As shown, the punching section comprises three sets of equally spaced

punches

135, 136 and 137 (see Figs. 1 and 3). When a card is at its initial position to be punched, the sets of punches are correlated with certain card columns.

-For a column card, at the starting position of the card, the sets oi punches will be correlated with card columns 1, 16 and 31. Considering a single set of punches which is selected for punching serial numbers, ilfteen successive steps of movement will be necessary to punch one-third of the card. As the serial number counter is shown as having only three orders, only three steps of movement are used ior actual punching operations for punching serial numbers.

For each set of punches, a set of 'controlling

magnets

141, 142 and 143 (see Figs. 1 and 5) is provided. When any magnet is energized, its related armature 144 will be attracted downwardly, resulting in the depression of the actuator member 145 which carries a pawl 148. Depression of pawl 146 will cause a secondary actuator 148 to be rocked and one end thereof be brought inthe path of a continually turning fluted shaft 147 which, by means of a bell crank 149, causes depression of the related punch, all operating in the manner described in the patent above referred to :Io carry the card step by step beneath the punches, a card carriage comprising clips The plate 157 is guided fer aviongicudmal movement by a roller 175 (Figs` 3 and 4) rolling over a fixed rail 176. Secured tojthe plate 157 is a .bracket member 177 on which is pivotally plate 178 to effect a subsequent intermittent movement of the card carriage. The driving connection for driving the carriage is effected whenever a card is presented to the punching station B end is .preferably controlled by the 185 adapted to close contacts 186 when a card. engages the lever 181 and rocks the same. A bell crank lever pivoted to a bracket 187 (Fig. 3) attached to guiderail 176 has a pin 188 at the extremity of one arm thereof engaging a slot 189 formed in rack plate 178. The other arm of the bell crank has a curved portion 190 and a tip 191. The bell crank is free to be rocked about its pivot to the position shown in Fig. 3 by a spring 192 when the stop portion 184 (Figs. 1, 3 and 4) of lever 183 is brought out of engagement with the tip 191 as an incident to the presence of a card in the punching station, permitting the spring to rock the rack plate 178 upwardly into a driving engagement with the

worm

179, 180. If a card fails to feed to the punching station the stop 184 will be retained in front of the tip 191 preventing a driving engagement between the card carriage and the driving parts of the machine. In mesh with a worm 193 is a worm gear 193' to which is attached a mutilated gear 194 the teeth of which mesh with either one or the other of two sets of teeth of a mutilated pinion 195 pinned to a shaft 196. The design of the parts is such that each revolution of the mutilated gear 194 will eiiect a complete rotation oi' pinion 195.

part of the stud 199 is in the plane of the curved extension 190 while the other part of the same stud is in the plane of the bracket plate 177 and adapted to engage an edge 2000i a notch therein to return the card carriage toits normal position.

When the teeth of the mutilated gear 194 (see Fig. 4) engages the teeth-of the mutilated pinion 195 they will turn the arm 197 from a horizontal position, one end of stud 199 engaging the curved extension 190 rocking the bell crank and withdrawing the rack 178 out oi' driving engagement with the worm teeth 179-180 at the end of the feeding movement of the carriage. Thereafter the other end of the stud 199 will engage the edge 200 to quickly shift the carriage reversely when the card isbeing released from the clips in the manner disclosed in said patent, one end of the stud 199 contacting with the underside of the curved extension 190 to retain the separation between rack 178 and worm wheel 179-180 (lllv ing the restoring of the carriage. As the stud 199 leaves the tip 191 the spring 192 will be eil'ective to causev a subsequent engagement of worm 179-180 and rack 178 if the arm 184 is now out of stopping position as determined by the presence of a subsequent card fed to thepunching section B (see Fig. 3). If a card should not be fed to the punching station the arm 184 will stop the movement of the bell crank which controls the position of rack 178 to prevent a driving engagement withworm 179-180 to feed the card carriage.

A supplemental card lever 205 (Fig. l) asso- .v

elated with the analyzing section A of the ma-v chine is adapted to close contacts 206 when a card is in this section, but as the analyzing section is not involved in the present invention the function of such a section will not be explained except tosay that when punching serial numbers a card will be in section A to close contacts 206.

Referring to the circuit diagram (Fig. 5) it will be observed that current for the electrical instrumentalities is supplied by

line wires

207, 208 to energize the driving motor 209 when a switch 210 is closed. Considering for the purposeof explanation a plurality of punching stations, current is supplied to the

magnets

141, 142 and 143 from the line side 208 by a wire 204.

Supported by the card carriage is a vplate 220 against which bears a brush 203 in any position of the plate.

Coming now to the present invention it is sometimes desirable to automatically punch cards to indicate serial numbers. A preferredmechanism provided for this purpose is shown in Figs. 6, 7 and 8 wherein it will be observed that the serial numbering control device comprises a series of

ratchet wheels

240, 241, 242 of successive denominational orders and' which are adjusted diil'erentially by a series of

pawls

243, 244, 245 havin'g units ratchet wheel 240 a step and when a com- Y plete revolution of thel wheel has been effected, the pawl 243 drops into a deep notch 240' (Figi 6) which permits the adjacent pawl 244 to step I the next higher order wheel 241 a notch. Such serial numbering wheels and transfer devices are well known in the art of registering devices and need not be explained in further detail.

The preferred means for actuating the set of pawls comprises a magnet 246 (Fig. 6) which'. at-

tracts its armature 247 when it is energized thus rocking the pawl carrying frame 248 through a link 249, restoration of the parts being eected by a return spring 250.

As shown in the circuit diagram in Fig. 5 magl net 246 is in series connection with cam controlled contacts 252, a manual switch 253, and the

cardA

241 and 242 is a series of gear wheels 254 adapted through idler pinions 256 to` set a series of gear wheels 257 to each of which is secured the related one of a series of indicator Wheels 258, 259 and nosas l a plurality of segments 264 the particular one in contact depending upon the representation of the umts counter wheel 240. Each of the segments 264 have wire connections 265 (Fig. 5) to plug sockets 266 which may be plugged up to the selected set of

magnets

141,4 for example, by plug connections 267.

A similar commutator device is provided for the tens and hundreds counter wheel so that the segments that are connected to control the energization ot the various magnets depend upon the standing of the respective counter wheels. Further, it will be observed that the conducting

segments

263, 268 and 269 are connected to plug sockets 27la by plug connections 270 to a selected series of stationary segments 271. A contact plate 272 carried by the plate 220 secured to the movable card carriage is adapted to successively contact said segments 271 as the carriage is intermittently stepped.

If, for example, it is desired to punch serial numbers in certain columns one of the several series of

punch magnets

141, 142 and 143 will be selected by plug connections 267 (only two being shown) with respect to the section in which are the columns to be punched. If the columns selected comprise columns l15 inclusive, magnets 141 are plugged for control by the numbering devices; for columns 16-30 inclusive magnets 142 are selected, and for columns 31-45, in the last section, magnets 143 are utilized. 'Ihe plug connections 270 are made in accordance with the desired columns oi' the section selected.

When contact plate 272 successively contacts the segments 271 shown plugged to the commutator devices, closed circuit connections will be made successively to certain magnets of the selected set 141. For example, li the reading of the commutator device lis 421 as shown in Fig. 5 and the connections made as shown, the following operations will take place.

When contact plate 272 (Fig. 5) contacts the ilrst segment 271 which has a plug connection 270 a connection is made from line wire 207, card lever contacts 206, card lever contacts 186, brush 203, plate 220, brush 272, the segment 271 leading to the units border segment 263, brushes set 141 so that the three card columns selected will be successively perforated to represent 421 as the carriage is being stepped.

As explained fully in the patent when a card is released after it is punched, it is fed by rollers 160 to the analyzing section A and then by rollers 167 to a receptacle.
