3 Claims.

This` invention relates to improvements in record controlled tabulators and has particular reference to card analyzing means therefor, the present disclosure being a division o f my co-pending application Serial No. 13,017, led March 4, 1948.

An object of the invention is to facilitate access to the interior of the card analyzing mechanism of a tabulator in the event of a card jam so that any mutilated cards therein may be readily and quickly removed, and to also enable repairs and replacements to be made with comparative ease. Another Vobject is to provide the analyzingvl section of a statistical card machine with relatively movable frames each of which contains certain operating and control mechanisms that cooperate inthe ranalysis of cards and in the transmission of such analysis to other parts of the machine, and wherein a drive for ksaid mechanisms is mountedy in one of saidfframes for detachable connection to portions of the mechanisms in the otherframe to permit of said frames being relatively moved apart to open position.

In-carrying out the above objects, the invention provides a construction in which the analyzer section of the tabulator comprises, generally, a main frame :carrying portions of the card analyzifn'gY mechanism including one of the plates forma partof a chamberinto which cards are fed for analysis, and an auxiliary frame movable to open position relative to the main frame and supporting therein, among other elements, portions of the analyzing mechanism anda second plate which cooperates with the rst plate to form said card chamber and which is movable with said auxiliary framewhen the latter is adjusted to openposition, to support the two plates of the chamber and thus fully expose for ready access and removal any cards in the analyzing section.

The inventive idea involved is capable of receiving a variety of expressions one of which, for purposes of illustration, is shown in the accompanying drawings; but it is to be expressly understood that said drawings are Aemployed merely to .facilitate the description of the invention as a Whole and not to define the limits thereof, reference being had to the appended claims for this purpose.

Inthe drawings:

Fig. l is a fragmentary side elevation of the analyzing section of a tabulator constructed in accordance with the invention;

Fig. 2 is a view similar to Fig. l, partly in section, showing the upper auxiliary frame of the analyzing unit in partially open position; andV Fig. 3 is a fragmentary vertical transverse section through the analyzing unit.

The analyzing section comprising the features of this invention includes the front and back plates 3i and 32 and a transverse wall 35 suitably carried upon the base of the tabulator, the wall separating said analyzing section from the remainder of the machine which forms no part of the present invention and by which the analysis of the record cards is transferred to the printing and accumulating mechanisms of the tabulatorl for the control thereof. Said plates 3|, 32 constitute the main frame of the analyzing unit and have pivoted to the upper portions thereof, at 38, the two rails 39 of an auxiliary frame which further comprises the side plates 40 and 4I and a cover plate 42, said pivotal connection permitting said auxiliary frame and the entire mechanism supported thereby to be swung upwardly to a substantially vertical position, after effecting certain disconnections to -be later described, in order that ready access may be had to the interior of the analyzing section. The auxiliary frame is held in its horizontal operative position by removable dowel screws 43 extending through the rails 39 and into the side plates 3i, 32, and to adequately support said auxiliary frame in its closed posiv tion the opposed side rails 39, which are laterally oifset relative to the plates 3|, 32, carry blocks 44 which rest upon the latter plates, as shown in Fig. 3.

to one end of the transverse shaft 58 (Fig. 2) having bearings in the plates 3l, 32 and Operable to control the various functions of the analyzing section of the machine, as fully set forth in the above identified application.

Pairs of upper and lower card feed rollers 'l'l have their shafts supported in the plates 3|, 32, those rollers shown in Fig. 3 being the intermediate pair located vertically between the sensing and analyzing stations generally indicated at 19 and 8l at which cards are compared for group control purposes. The shaft of the lower roller of said pair extendsthrough the front plate 3| and is geared to the horizontal counter shaft 98 by a worm 99, and similar pairs of rollers are also geared to the latter shaft and to the shaft on the rear side of the machine so that the various pairs of rollers will operate in unison to feed cards ejected from the magazine 63 carried by the side rails 39 and transmit them to and 3 through the card chambers 18 and 80 at the stations 19 and 8|, after which said cards are deposited by the last set of rollers 11 to the left of Fig. 2 into a stacker chamber (not shown). A picker mechanism offthe usualt type is utilized to feed cards from the magazine 66 and is operatedA from the rock shaft 1| connected through the crank 12 to a link 13 actuated by bell crank 14 controlled by a cam (not shown) onthe shaft 58.

The two mentioned stations 19, 8| include, re-v spectively, the vertically reciprocating lower pin boxes |03 and |03a that contain the' sensingl pins |64 by means of Which'perforations in the cards at said stations are simultaneously sensed while cards are momentarily heldin the card' chambers by the card stops= 82'- pin boxes are of identical construction except that the box |33a contains an additional pin. |04 in each row individual to a card column and used for control purposes. Stations 19, 8| further comprise the upper pin boxes |09', |`09a supported in position above' the pin boxes |03, |03a by attachment to the blocks 44 on the' rails' 39 so as to be movable with' the latter and carry with them the card stops 82 when the auxiliary frame of which said rails form a part is swung' to open position. Secured to the pin boxes |09, |09a are the upper plates 18a and 88a. which cooperate with the lower plates 18h, 80h to'form the card chambers 18, 88, the' latter plates being ailixedto rails 83k secured to the side plates The upper pin boxes |09, |0911' contain, respectively, the rows of pins ||0, which are controlled by the sensing pins |04' in the lower pin boxes and when. said pins H', are elevated by said pins |4 passing through perforations in cards being sensed at the two stations, lock plates ||4 in the upper pin'boxes momentarily hold' those pins H8, elevated which have been raised bythe pins |04 during' the sensing and analyzing operations'. The lock plates ||4 are under the combined control of reciprocating. cross bails ||5, only one of which is, shown herein. As fully described insaid' copending application, said plates areshifted into locking position relative to elevated pins H0, I|| and remain in suchv position until' the bails are returned to restore' said plates andthereby release the elevated pins following th'eperformance of their functions. A rock'shaft |8'con'trols the reciprocation of the bails to shift the lock plates into locking position and saidshaft'c'arries a crank |20 to which is' detachably connected a link |2| joinedv to a lever' |22' operated" by a cam (not shown) onthe shaft 58.

The card stops 82 are controlled from a cam on said shaft' 58 engaging a lever |25 which is directly in front of the lever |22 and to which is connected a link |26 that is detachably joined to a rock shaft |21 which controls the operation of said stops.

y From the construction thus far described, it will now be apparent that when the upper auxiliary frame is swung to open position about its pivots 38, the upper pin boxes |09; |09a and' the. upper plates 18a. and 80a, and other mechanism to be described which is contained in said frame, will be separatedfrom the lower pinboxes |03, |03a and the chamber plates 18h, 8017 to thus fully' expose the feed rollers 11 and' open the card chambers 18, 80 so that mutilated?- cards may be easily removed in the event of a card' jam in the analyzer, or. shouldit bedesired to' effect` repairsit'o or replacement of parts thus exposed.

The two lower Cooperating with the pins ||0, in the up'-l per pin boxes is a reciprocating scanning device generally indicated at 2|| and whose reciprocation is controlled from the shaft 58 by complementalv cams 2|-2" thereon acting upon levers 2|`5, 2'||5 onone sidev of the machine cone nected by a cross bar 2|1, there being a similar arrangement of levers on the opposite side of the machine also controlled by complemental cams 2|`2. The lever 2|8 on one side of the machine and its equivalent 2|6a on the other side thereofextend upwardly and are detachably joinedy to4 links 220 and 220er connected at 22| to the scanning frame so as to reciprocate the same. The scanning frame, as fully described insaid co-pending application, carries sensing pawls- 223Y which. travel over the pins ||0, in the two upper pin boxes and are tripped by elevated pins therein to, control the movements of Aslides 225 which, in turn, control the operation ofv bars |36 forming part of the data transfer mechanism (not shown) located to the left of the wall 35, and also actuate bell cranks' 243 forming part of a change of designation control mechanism contained within the upper part of the auxiliary frame between the plates 40, 4|', said mechanism further including the setting keys 263 for controlling the type of totals' to be taken upon a change of' designation.

There is also shown one of a number of bars |31 (Fig. 2) which extend through the wall 351 and into the transfer mechanism mentioned above, each of said bars being controlledV from an additional control pin in the box |090.- that has an extension ||3 that trips the lever |45 when' said pin is elevated by the previously mentioned' additional' pin |04' in'the lower pin box |03a. Allof' the levers |45 are carried by a' common bail: 229 which is rockingly supported on the'shaft 230 extending between the rails 39' and' said' shaft is controlled by'a cam on the shaft 58 which op'- erates a bellcrank 232. A link 223` detachably connects saidv bell crank` to an arm carried by the rock shaft 2'30so as to turn the latter clockwise to operate said bail and thereby cause 4any lever |45 tripped by a control pin ||3 to impart movement to its' associated bar' |31'. This' act'ion" ofthe bail'takesplace before'the scanning device 2|| starts its movement to the' right andthe` b'ail" is thereafter restored by the'spring 2'35 connected to the bell crank'232;

A panel 300 is' attached. to the wall' 35 and carries the' switches andkeys employedV for acfcomplshing various controls of the machine.

With the'pa'rts in the position of Fig. l', should it be desired to open theV analyzing unit', itis only necessary to remove the dowel screws 43 and'un latch the keepers 30| to' disconnect the' upper ends. of the leversland' links |'2|', |26, 2|B, 2`|8u` and 223 from their respective crank arms and links on both sides of the machine, whereupon the entire auxiliary frame and parts supported* thereby may beswungupwardly about the pivots 38 to open position.
