  • the sorting machine with which the printer ⁇ counter cooperates is provided with a magazine 10 (see Figs. 20 and 21) for holding a stack of cards 11, the bottom one of which is engageable at the rear by picker blades 12which feed it from the magazine through the card throat 13 into the grip of feed rolls 14.
  • Each picker blade is mounted at the rear of a slidable arm 15 reciprocated by an oscillating arm 16 pinned to a shaft 17.
  • One of the arms 16 is pivotally connected to a link 18 which is journalled on a stud 19 fixed to a crank arm 20 on a shaft 21.
  • the right hand end of the shaft 21 has fixed to it a gear 22 which is rotated by a worm gear 23 fast to a shaft 24 which is driven by the shaft of the sorter motor M (Figl ⁇ 22) in any suitable manner.
  • the pickers 12 feed a card each cycle to the feed rolls 14 which advance the card over the analyzing contact roll 25 and under the analyzing brush 26.
  • the rolls 27 continue to feed the cards to the pockets one edge of one pocket being indicated at 28 in Fig. 20 in accordance with the analysis by the brush 26 of the index points of a selected column of the card.
  • the brush may be adjusted to sense any desired column of the card. It is fixed in a holder 30 (see Figs. 3 and 20) which has .narrowed ends 31 fitting in notches 32 of a pair of opposing frame members 33.
  • the notches are numbered in alignment with the columns of the cards as they pass under the holder.
  • a shaft 34 (Fig.
  • the shaft 34 is rotated clockwise as viewed in Fig. 20, as a result of which the intermediate portion of the shaft moves oif the top of the holder releasing it and permitting the operator to lift it by the hole 37 completely out of the notches it is occupying and replace it in the desired set of notches.
  • the shaft is then rotated counterclockwise to again position it over the holder to keep the latter in place.
  • the action of the sorter in selecting the pocket for a card may be briefly outlined.
  • a card is fed each cycle between the analyzing contact roll and brush by the feed rolls 14.
  • the brush successively senses the index point positions of the selected card column.
  • the forward edge of the card moves over the table 40 (Fig. 20) to positions in front of the successive guide blades 4l. If a perforation occurs, for example, in the fourth position of the card from its leading edge. the latter will be in front of the fourth guide blade from the right.
  • counter bank 61 has a set of five wheels 62 while the total counter bank 63 and he grand total counter bank 64 (Figs. 7 and 9) have six wheels.
  • a friction disk 60 is located on each side of a counter wheel. Between adjacent banks of counters, compression springs 65 attached to the outer friction disks of the banks urge the counter wheels and disks into close frictional contact. As the friction disks keyed to shaft 56 rotate, they tend to rotate the wheels. The latter are prevented from following the disks by pawls 66, the nose 67 of the pawl engaging the longer side 68 of the notches 69 in the escapement wheel plate 70 to prevent the latter moving clockwise as viewed in Fig. 14.
  • the plate 70 is rigidly attached to the counter wheel which has ten type lugs 0 to 9 disposed around its periphery.
  • the escapement plate is within a recess formed by the periphery of the printing wheel which extends as an annular flange 71 from the side of the wheel.
  • On the inside of the flange of each unit wheel of a bank are equally spaced lugs 72 each adjacent a corresponding type lug and escapement notch.
  • the pawl nose 67 is sufficiently narrow where it protrudes into the recess of the wheel to pass with clearance between the top of lug 72 and the periphery of plate 70, and when engaging the notch side 68 is a slight distance above the top of the adjacent lug 72.
  • Each unit pawl has a lateral extension 76 comprising the armature of an actuating magnet 77 (Fig. 5), which is provided for each designation counter bank and similarly an extension 76 comprises the armature of an actuating magnet 77 (Fig. 9) provided for each of counter banks 63 and 64.
  • the deenergization of the magnet and the action of the spring 78 lag to the extent that, unless means were provided to prevent it, the wheel would move more than one step after its release by the pawl thereby adding more than one to the wheel reading.
  • the means for preventing this occurrence comprise the pawl nose itself and lugs 72.
  • a lug Fixed to the highest order printing wheel 62 of each bank, shown in Fig. 15, is a lug which is adapted to engage the right side of the nose 67 of its restraining pawl to prevent said wheel from moving all the way from 9 to 0 position which latter position would give an incorrect reading.
  • the lug 85 stops the wheel 62' after the wheel has moved relative to the index line R about midway between the 9 and 0 positions. Therefore, the wheel will not present any type lug at the index or printing position R.
  • the wheel 62' which is mid-way between the 9 and 0 positions at the index line R will not print on the sheet. This indicates that the counter bank containing this wheel 62 has exceeded its counting capacity and therefore that the count of this bank is in error.
  • the position of the pawl nose 67 of a wheel is such that it stops the adjacent lower order wheel in its 0 position relative to the index line R.
  • the highest order wheels 62 are stopped with their 0 type in index position R duringthe reverse movement of the shaft (which is counterclockwise in Fig. 15) by contact of the right side of lug 85, as viewed in Fig. 15 with the right side of the nose of its own restraining pawl.
  • shaft 56 is seen j to extend past total counter bank and terminate in a reduced circular bearing end seated in a corresponding hole of shaft 56 of the grand total counter bank.
  • Shaft 56 releasably drives shaft 56' by the following means.
  • Shaft 56 has a sleeve 91 fixed thereto encircling the reduced end rod 90.
  • the peripheryof the sleeve 91 has a notch 92 therein into' which a ball 93 is yieldably urged by a spring 94 adjustably held in a collar 95 surrounding the shaft 56'.
  • the collar 95 has a portion entering the key slot 59' of the shaft thus forcing the shaft to rotate with it. lNormally the rotation of shaft 56 in any direction will rotate shaft 56 through the sleeve 91 the notch 92 therein, the ball clutch 93 and the collar 95.
  • shaft 56' may be prevented from moving.
  • the outer end of shaft 56' has pinned to it a notched vwheel 96.
  • the nose of a pawl 97 pivoted to the side of the counter housing is adapted to engage with the notches of wheel 96 and stop movement of the wheel and the shaft 56 rigid therewith.
  • the pawl 97v has a pin 99 seated in a notch 100 in the lower end of a lever 101 the hub of which is freely rotatably mounted on the terminal portion of shaft 56.
  • a coil spring 102 having one end xed to the terminal portion of shaft 56 and tightly encircling the hub of the lever 101 tends to rotate said lever with said shaft.
  • the counter bank may be Zeroized together with the other counter banks during reverse motion of shaft 56 by the operator grasping the handle of lever 101 and pressing the lever in a clockwise direction to force it to remain in the position shown in Fig. 8 thus keeping the nose of pawl 97 out of contact with wheel 96. The latter not being restrained will not restrain shaft 56.
  • the ball clutch driving connection between shafts 56 and 56' will then drive shaft 56 in a reverse direction so that counter bank 64 actuated thereby will be zeroized in the same manner as the other counter banks.
  • Figs. l, 2, 5. 6, 8. and 9 illustrate the means for taking a printed reading from the type lugs of the counters at the index line R (see Figs. 8, 14. 15, 18, and 25).

  • the plates 122 support between them a hollow substantially cylindrical paper roll holder comprising a lower half 125 rigid with plates 122 and an upper half 126 hinged to the lower half.
  • a pair of arcuate strips 127 are provided having a broad portion 127 which when moved to embrace the lower half of the holder does not interfere with movement of the upper half of the holder on the hinge to open position shown in Fig. 4.
  • the strips are moved by handles 128 thereon so that Athe broad portion 127 moves over the upper half of the holder it will prevent the upper half from moving and keep the holder closed.
  • the side plates 122 fixedly carry a table 130 (Figs. 1, 5, and 6) having an intermediate elongated slot 131 through which projects an elastic strip 132 preferably in the nature of a rubber band the ends of which are held between clamp plates 133 rigid with a index position by a roller 135 when the latter me is moved along the back of the strip.
  • the roller is rotatably mounted between the top and bottom plates of a frame 137 to the rear of which the handle 136 is fixed.
  • the frame is slidably mounted on a rail 138 fixed to the side plates 122.
  • Rollers 139 journalled between the top and bottom plates of f rame 137 serve to reduce the friction between the rail and the frame.
  • a notch 140 is provided with which a spring-pressed ball 141 (Fig. 6) carried in the handle 136 cooperates to yieldingly hold the frame 137 at each end of its movement.
  • the paper sheet 124 from the roll of paper in the holder -126 is brought through the front thereof over the table past the platen strip 132 and between a plurality of rubber or felt covered feed rolls 145 and cooperating rolls 146. After passing between these rolls the paper is led between guide plates 147 and 148 rlgidily carried between the side plates 122 on bars 149 and 150 respectively.
  • the edge 151 (Fig. 5) of the plate 147 serves as a cutting and straight edge along which the sheet of paper may be out olf.
  • the effect of the springs is to yieldinglyhold the flat side of shaft 154 in contact with the straight edges 156 of the plates 152 in which position the rolls 145 and 146 grip the paper.
  • the shaft 154 is rotated thereby camming plates 152 outwardly and separating rolls 145 and 146 between which the paper may now be inserted.
  • the sheet of paper is automatically fed forward a predetermined, adjustable, distance during the printing operations.
  • the printing frame including the side plates 122 and the entire mechanism carried thereby is adjustable to three different positions about its axis.
  • Fig. 5 shows the lower position which it occupies when the sorting operation and the counting operation is taking place. In this position. there is no possibility of accidental interference with the motion of the counter wheels.
  • the weight of the printing frame holds .it in the lower position which is fixed by contact of studs 160 carried by each plate 122 with the top of projections 161 of concave'ly curved bars 162 fixed to the base 120 adjacent each plate 122.

  • Shaft has rigidly connected thereto at its right hand side a concentric shaft 172 (Fig. 9).
  • Freely encircling the shaft 172 is a pinion 173 (Figs. 8, 9 and 10).
  • Rigid with the pinion is a sleeve 174 within whichds pivoted a pawl 175 normally urged clockwise by a spring 176 connected at opposite ends to the pawl and the i sleeve.
  • a ratchet wheel 177 located within the 100 sleeve and freely mounted on shaft 172 is adapted to cooperate with pawl 175.
  • the pinion 173 rolls on rack 171 and rotates counterclockwise on its axis as viewed in Figs. 8 and 10.
  • the sleeve 174 and pawl 175 rotate with the pinion and consequently the nose of pawl idly rides over the teeth of ratchet wheel 177.
  • pawl 175 protrudes through a slot 178 in sleeve 174.
  • a ring 179 Surrounding the sleeve is a ring 179 having a long slot 180 in its periphery into which the outer end of pawl 175 projects.
  • the ring 179 is provided with notches 182 and 183 cooperating with a pin 184 on the end of a pawl 185 pivoted to the frame plate 122 and urged towards the ring by a spring 186 (see Fig. 10).
  • the ring 179 is freely movable on sleeve 174 but is releasably retained in set position by coaction of pin 184 of pawl 185 with either of notches 182 or 183.
  • Notch 183 is shaped so that pin 184 restrains ring 179 from clockwise movement beyond the position shown in Fig. 10 but permits counterclockwise movement.
  • Notch 182 is shaped so that when pin 184 is seated therein, the pin prevents further counterclockwise movement (Fig. 10) but permits clockwise movement.
  • the ring 179 is accessible to be turned by the operator (see Fig. 9).
  • the parts and movements are so proportioned that the pawl 175 will always move the ratchet Wheel a distance equal to a multiple of the space between teeth so that when the movement of the wheel is completed the pin 190 will be engaged with a notch 189 in the collar 188 fixed to the wheel. Due to this engagement when the pawl 175 during its next counterclockwise movement rides over wheel 177 it will not frictionally and undesirably move the wheel Ycounterclockwise.
  • the collar 188 has rigidly fastened thereto a sleeve 200 within which is a coil spring 201 (Figs. 9 and 12) loosely surrounding the shaft 172.

  • the knob end 209 of member 208 may be pushed forward to cause the inner end of member 208 to engage the inner ends of dogs 203 and move them against spring 201 to the full line position shown in Fig. 12. In this position, the outer ends of dogs 203 are released from the inner surface of sleeve 200. Thus rotation of sleeve 200 can have no effect on dogs 203 when the member 20B is moved inwardly.
  • the knob 206 may be grasped by the operators hand with the palm pushing knob 209 inwardly and shaft 172 turned through collar 205 independently of sleeve 200 and the actuating means for the sleeve.
  • the shaft 172 may be manually rotated to ⁇ be rotated manually. During such manual opfeed the rolls 145 and the paper forward any desired distance. When the paper is again fed automatically the relation between the pawl 175 and wheel 177 not having been disturbed the completion of the automatic feeding movement will find the pin 190 in a notch 189 to lock the ratchet wheel against accidental reverse rotation.
  • the amount of motion of gear 173 and the pawl 175 is obviously the same each downward movement of theprinting frame and the same each upward movement o f the frame but due to the adjustability of the ring 179 the pawl 175 engages the ratchet wheel 177 during the upward movement of the frame at adjustable times so that the amount of rotation of the wheel 177 is variable and the paper accordingly may be fed forward different amounts.
  • a knob 210 by which said shaft and the feed rolls 145 carried thereby may 05 eration the ratchet wheel 177 and collar 188 rotate with the shaft and the operator hearing the click of the pin 190 entering the notches 189 in the collar is enabled to stop the rotation of the shaft when the pin 190 is in one of the notches 189 thereby preserving the correct relation between the ratchet wheel 177 and the pawl 175 for an automatic feeding operation.
  • Ribbon mechanism is provided to support a ribbon 211 in front of the counter wheels at index posltion R (Fig. 14).

  • the ratchet wheel is coupled to the spool 212 hence rotation of the wheel results in similar rotation of the spool to wind the ribbon thereon.
  • the purpose of the yielding drive provided by 11k spring 227 between link 224 and lever 226 is to permit link 224 to remain stationary when the ribbon, ratchet wheel 216, or spool 212 is prevented by some accidental cause from moving.

  • plug 278 If plug 278 is placed in socket 281 there will be no connection to the counter and the combined sorter and counter will operate only to sort cards.
  • a counter commutator (Figs. 13, 21, and 22) is provided, the stator 296 of which carries the contact studs 297 arranged circumferentially around the opening 298.
  • the rotor 299 is operatedby the sorter motor M so as to cause the brush 300 carried thereby to engage the contacts 297 synchronously with the feed of the cards.
  • a second brush 301 carried by the rotor engages a commo-n contact ring/ 302.
  • a circuit is also completed as follows: From the plus side through the analyzing contacts, plug 278, line 303, line 309, magnet 310, brush 311, circuit breaker 312, brush 313, line 314, brush 287, commutator 239, brush 291 and contacts'292 to the minus side.
  • the energization of magnet 310 attracts its armature 315 to open normally closed contacts 316. The armature is latched in its open position for the remainder of the cycle in a manner well-known in the art.
  • Circuit breaker 312 is timed to prevent closing of a circuit through magnet 310 when the analzing brush contacts the bare roll after the card leaves the brush 26.
  • the closing of a circuit through magnet 310 at this time would undesirably open contacts 316.
  • Contacts 316 are in a circuit established at the beginning oi the cycle before magnet 310 can be energized to open contacts 316. This latter circuit is from the plus side through line 345, brush 346, contact roll 347, brush 348, magnet 349, magnet 317, contacts 316, line 335, and circuit breaker roll 336 to the minus side.
  • Magnet 349 closes armature contacts 350 thereby forming a circuit shunting the roll 347, through lines 345 and 351, contacts 350 and as before.
  • contacts 316 in series with magnet 317 in the same circuit are opened by magnet 310 as previously explained.
  • Accord' ingly magnet 317 is deenergized and contacts 318 are open so that the circuit through reject magnet 77 cannot be made.
  • the accumulating total and total counter magnets 77 are energized at the beginning of the cycle each time a card is fed.
  • card lever contacts 325 distinct from the ordinary sorter card lever contacts 270 are provided. Contacts 325 ⁇ are closed by the card as it moves towards the analyzing brush, engaging the horizontal arm 326 (see Fig. 17) of a bail and rocking the vertical downwardly extending arm 327 of the bail to the right' (as viewed in Fig. 17). The end of arm 327 moves contact blade 328 towards contact blade 329 to close the card lever contacts 325 carried by said blades.
  • a circuit is made from the plus line through brush 330, the conductive portion of contact roll 332, now engaging brushes 330 and 333, card lever contacts 325, magnet 334, magnet 293, line 335, and circuit breaker 336 tothe minus side.
  • Magnet 334 upon energization closes contacts 337 establishing a circuit shunting card lever contacts 325 and roll 332 from the plus line through line 345, contacts 337, magnet 293, and roll 336 to the minus side.
  • the purpose of making this circuit is to maintain contacts 292 operated by magnet 293 closed until broken at the end of the cycle by the circuit breaker roll 336.
  • the plug 278 When it is desired to count from a column without sorting, the plug 278 is inserted in socket 355 which connects the analyzing brush to the counter only. If it is desired to count from one columnl and sort from another a second brush 26 is provided, supported andadjusted as brush 26. 'I'he plug 278 connected to brush 26' is inserted in socket 355 while the plug 278 is inserted in socket 281.
