Definitions

  • This invention relates to machines for sorting statistical cards.
  • Machines for sortin perforated cards of the kind used in automatic accounting and tabulating machines are well known and in such machines the cards are passed from a sensing box into one or another compartment according to the designation of the card.
  • the cards are handled in pairs.
  • each workman may be provided with a deduction card which is made out previously Whether the man has worked or not, and bears indentification particulars, insurance particulars and deductions which are fixed at a standard rate, and also a wages card is made out which shows the number of hours that have been worked during a week.
  • the deductions cards are functionally non-per-
  • the deduction cards may, however, be perforated in a particular zone so that they may be automatically brought together with their wages cards by passing them through a sorting machine, that is to say, each of the cards, both deduction and 419,880, and. in. Great Britain April 5, 1929.
  • wage cards may be punched with the identification number of a particular workman and by this means brought together by passage through a sorting machine when they will be ready for tabulating purposes except for the inclusion of deduction cards where they are not associated with wage cards.
  • the paired and separate deduction cards are then passed through a sorter as hereinbefore described, the sensing box being arranged so that the passage of the wage cards controls the openingof the compartments whilst the deduction cards are inoperative and merely pass through the machine unless they are passing into a compartment held open by the previous passage of a wage card.
  • a sorting machine in accordance with the present invention comprises in combination with sensing pins operating means for selectively rendering available receptacles for the sorted cards, means for prolonging for a. predetermined time the period during which any of the said receptacles remain available, whereby a number of associated cards is directed into one and the same receptacle.
  • the machine may comprise a, plu' rality of compartments of which one or more are opened on the passage of a key card, such as a wage card, and retained open for the passage of the following card such as a deduction card associated with the, wage card.
  • a key card such as a wage card
  • Fig. 1 is a diagrammatic pictorial sketch showing only so much of a sorting machine as is necessary to explain the present invention
  • Fig. 2 is a sectional elevation through the timing shaft of the machine illustrated in Fig. 1, showing the release means employed according to the invention, the release being shown in operative position.
  • Fig. 3 is a detail elevation showing the release means detached and to a larger scale, the release being shown in inoperative position.
  • Fig. 4 is a view similah to Fig. 3 showing a modified arrangement but with the release means operative;
  • Figs. 5 and 6 are views similar to 4: showing the means of timing the retraction of the release means
  • Fig. 7 illustrates a detail
  • the carriage comprises transverse members 1, 1a, carrying the sensing pins P and the carriage is movable laterally on guides, not shown, so as to bring the pins over a particular column of perforations in the perforated plate 2.
  • a card G is introduced over the plate 2 by mechanism, not shown, and above the plate 2 is a stripper, also not shown, and which prevents the card being raised when the pins are retracted.
  • each pin P and below the perforated plate 2 are a series of suitably mounted spring pressed plungers 3, there being one plunger for each sensing pin P on the carriage and beneath each plunger is the end 4 of a wire comprised in a Bowden cable system indicated at B.
  • each sensing pin P on the carriage there is a compartment into which cards sensed by the pin P are directed.
  • One such compartment is indicated as disposed between the dot and dash lines 5 the mouth of the compartment being covered by flaps conveniently in the form of fingers 6 so that while the linger 6 is in the position shown the mouth of the particular compartment is obstructed and the entry of a card prevented.
  • each compartment is com prised by a plate 7 spring supported as indicated at 8, and comprising a lug 9 which, when a predetermined number of cards have entered the compartment and the latter is thereby filled, the plate 7 being depressed by their weight at the expense of compressing the spring 8, will have reached a lug 10 mounted on a spindle ll carrying another lug 12 which, on the spindle being rocked by the members 9 and 10 coming together, rocks a lever 13 moving the contact at the end thereof away from a contact on the terminal 1a of an electrical circuit controlling the running of the machine, thereby when any compartment is filled the machine is stopped.
  • the compartments of the sorting machine are arranged in close succession and the fingers 6 obstructing their mouths abut head on tail so that they constitute a substantially continuous path or platform along which a card leaving the sensing box passes.
  • the cable B connected to the sensing pin is connected through timing gear including a disc T by the agency of which gear a cranked arm 17 is bodily lifted thereby rocking a shaft 18 to which is fixed by means of blocks 19 the fingers 6 so that the operation initiated by the passage of a sensing pin P through a card causes the respective arm 17 to be raised and consequently the fingers 6.
  • a card leaving the fingers over the preceding compartment passes under such lifted fingers 6 and falls into the compartment.
  • the timing gear for each arm 17 includes a plunger, not shown, actuated through the bell crank 20 rocked by the Bowden mechanism B.
  • This plunger stands in the path of plates such as 21 of which there may be si on the disc T (but one only is completely shown in each disc T illustrated) equally spaced in a circle therearound, each such cam plate 21 being pivoted as at 22 and car rying a link 23 movable over a pin 24 carried by the disc.
  • each link 23 is provided with a trip linger 26 which as the disc T rotates strikes a pin 27 towards the extremity of the arm 17, thereby the link 23 is moved on its hinged connection with the plate 21 and is free to slide back on the pin 24 of the disc T to quiescent position.
  • the discs T are required to operate synchronously with the carriage in the sensing box it is convenient to mount the discs T on a shaft 28 conveniently referred to as the timing shaft driven from the gearing reciprocating the carriage, and conveniently the shaft is carried in bearings 29 comprised in supports 30 suitably carried on longitudinal members 31 on the machine and which extend upwardly to form bearings indicated at 32 for the shaft 18 before referred to of the fingers 6.
  • Each bearing 29 is preferably disposed so as to be utilized for carrying a web member 33 from which depends a support 34 for the bell crank 20 operating the plunger which will pass through the web 33 and when projected stands in the path of the plates 21 of the timing gear.
  • the sets of rollers 15 are also driven synchronously with the feeding of the cards to the machine and these rollers preferably are driven from a shaft 35, conveniently referred to as a carry roll driving shaft, carrying bevels 36 which drive bevels 37 on the axle 38 of the rollers 15.
  • the card is positively pushed through the machine at a predetermined rate and the fingers 6 are lifted at a predetermined moment corresponding to their distance from the sensing box, whilst the passage of the sensing pin through a card determines which of the sets of fingers is to be operated.
  • the sorting machine is modified so that there are means for delaying the fall of the flaps so that a compartment can receive one or more paired cards with a perforating controlling card, for example one or more deduction cards following a perforated wage card, the latter causing the opening of the flap to a particular compartment and each flap is retained open according to the invention so that the paired deduction cards can follow the operative or what may be termed key card.
  • a perforating controlling card for example one or more deduction cards following a perforated wage card
  • a spring pressed latch L comprising a hook L which, when the arm 17 is raised, passes under the arm and holds it in raised position; the period of lift may vary and is determined according to the number of following cards and conveniently the retraction of the latch to permit release of the arm after the passage of one follower card is effected by cams L clearly shown in Fig. 3 mounted on the carry roll shaft 35, each cam L being provided with a pin L which engages the head L of the latch L and pushes it back about its the retraction of the hook L of the latch and consequently the release of the arm 17 which is then permitted to fall.
  • the cams L are adjustably set on the carry roll shaft so that they operate after pivot L causing correct elapse of time from the lifting of the respective arm 17 through the agency of the timing gear.
  • Fig. 2 clearly shows the latch engaged under an arm 17 and holding it in raised position, and the timing gear travelling under the arm towards the trip pin 27 on the arm and the cam L inoperative as regards the latch, but disposed to cause retraction of the hook L after the completion of the next revolution of the shaft 35 during which the follower card will pass into the respective compartment.
  • Fig. 3 shows the cam L after it has passed through an angle equivalent to the period of time permitted to elapse for the passage of a follower card and having engaged the head L of the latch causing it to be retracted and the arm 17 fallen to normal position. It may iere-be mentioned that the tails of the fingers 6 are cranked and abut against the rear wall of the compartment and accordingly, therefore, limit the rocking movement of the shaft 18 and consequently hold the arm 17 in hori- Zontal position just clear of the timing gear.
  • the latch engaging the arm 17 it may be arranged to engage a lug on the shaft 18.
  • the cam on the carry roll shaft 35 it is easy to adjust the position of the cam for the release of the arm 17 because the carry roll shaft makes one revolution for each card passing through the sensing box.
  • the invention comprises a means which is more simple than changing the gearing of the shaft 85 to vary the operation of the latch and this is disclosed in the construction indicated in Figs. 4 to 6.
  • the latch instead of providing L the latch L with a head I to be engaged by a cam L the latch, preferably the head, is provided with a star wheel L having preferably as many points as there are cards in a group considering the group of cards to be the wage 7 card which is perforated to operate the Bowden mechanism 13 and the associated follower cards.
  • the star is shown in six points. It will, therefore, operate to permit of five follower cards after the flap has been raised and the compartment opened as a result of the associated wage card pass ing through the sensingbox.
  • the star wheel is operated conveniently from the carry roll shaft 35 so that the star wheel is moved one step' as each card passes through the sensing box, hence the star wheel will make a complete revolution when a group of cards has passed through the sensing box.
  • the star wheel is provided with a pin L extending laterally and adapted to pass up a cam face L on a bracket L fixed to the side frame of the machine, and arranged so that when the pin L is forced against the cam face L the latch member is forced away from the bracket member causing a retraction of the hooked end L of the latch.
  • a spring L maintains a precise movement of the star wheel in accordance with the actuation effected from the arm L which is mounted on the shaft and carries a pin L which engages successively the points of the star as it revolves.
  • Fig. 4 the parts are shown in the position they attain as a result of the first card of a group passing through the sensing box and causing the arm 17 to be raised and the compartment opened.
  • the arm L on the shaft 35 moves the star wheel so that its pin moves up against the cam face L causing a retraction of the pin of the star wheel from the cam face and a corresponding movement of the hooked end of the latch so that the arm 17 is free and the compartment closed.
  • the arm L on the shaft 35 is adjustably carried to facilitate the setting of the arm L with regard to the star wheel L.
  • the star wheel L may be tapped on each point for the reception of a screwed pin as indicated in Fig. 7.
  • the star wheel may be provided with a plurality of pins, for example, three, in which case a corresponding reduction will take place in the number of following cards which will pass into a compartment before the compartment is closed.
  • t may be required to use the sorting machine in normal manner and to this end means are provided for withdrawing the latch from operative position.
  • the head of the latch is connected to a rod L which is provided with a pin L sliding in a slot L of a ring-like distance piece L.
  • the rod L is drawn backwards until the pin L is clear of the slot and the ring-like distancepiece is then rotated so that the pin overlies the head thereof and it is prevented from returning under the influence of the spring on the latch.
  • the delay mechanism may be employed for the sorting out of any form of key card associated with following cards and it is only necessary to alter the operation of the latch mechanism to assure that the following cards all enter the compartment opened by the passage of the key card, that is to say, that mechanism according to the invention provides a means of dealing with any form of statistical cards where in fact it is desirable to sort out small packs out of a stack although generally speaking a pack will only consist of two or three cards.
  • the delay means herein described for return of the movements of flaps of sorting machines comprising a plurality of compart ments has one embodiment only of the invention involving means for delaying the closure of the compartment and the invention is applicable broadly to any type of sorting machine where the fingers 6 covering the compartments extend over the respective compartments or extend in overlapped relation to the sensing box.
  • latch means may be provided in accordance with the invention for retarding the fall of the flaps after they have been operated so as to form the mouth or opening to the compartment thereby retaining the mouth open for the passage of the non-perforated cards.
  • a sorting machine need comprise but one compartment only, viz. that provided with the delay means preventing closing the mouth of the compartment so that the deduction cards can follow the paired wages cards when the flap of a compartment has been opened by the passage of a perforated wages card through the sensing box, whereas the deduction cards passing through and not paired simply pass over the compartment into a receptacle of any suitable form.
  • a disc such as T is employed with only one cam plate 21 and link 23 and the shaft on which the disc is mounted has to be geared to the carriage reciprocating mechanism so that the disc makes one revolution for each carriage reciprocation.
