Wattgamma-,1 Be it known that Ij',i J3.REnniKBosrno IBtrnL, a subject of the Kiiig. of Norway," residing at Similar Purposes,

- Ghristiania, Norway,

have invented certain new and useful Improvements in Automatic Registering Machines for Statistical and of which the following is a specification.

' This vinvention relates to machines for registering statisticalpand like particulars of the type in which cards provided with erforations corresponding to various numrs are usedtoclose electrical circuits by means of brushes making contact through the said perforations, the closing of .said electrical circuits actuating the registering mechanism. I

This invention also relates to selecting apparatus for use in registering machines of the type in which insulated contact plates arranged inone or, more arcs are provided and one or more selector-arms are adapted to rotate synchronously with the card feed ing mechanism so as, to make rubbing contact withfthe said contact plates.

'Acc'ordin to thefi present {invention the adding mec anism in a machine of the above and a plurality of toothed addin type consists of a mutilated {toothed wheel hav ng nine teeth only,- rotating synchronously'with the card feeding mechanism, wheels each of which adding wheels is a apted to be re1eased by an electromagnet'so as to en gage with atoothflonthe mutilated wheel corresponding to the numbenindicated by the erforation on the card and-to be rotate a corresponding number of teeth.

The invention also consists in a selecting chine of the ty e referred tozabove'charac terized by the eature'that'forl each arc of contact plates there is provided "a single electro-magnet which can be,connected to one or more of thfiontaetsfin the said arc; the said electro-mag'nets{actuating a switch to close a circuit'ready for; operating either the adding mechanism or a special flap for separating out the 'cardsor. for both, said" switch closing the circuit. nly on all the electro-magnets being actuated Referring now to the accompanying draw- 111 ig. 1 is a diagrammaticview showing the operation of the registering and selector mechanisms and 'Wheels. w

ri 2 is a detailed view of the adding In Fig. 1 of the drawings the .cards are moved by means of a feed device H one by one passed the selector contacts V V and registering contacts T T T,. On the same axis as the feed device there are provided rubbing contacts a, and 0 which, during the rotational motion, rub over arc-shaped contacts O 0,. These arc. contacts consist of plates insulated from one another and correspond in number with the number of numerals in the vertical columns of the cards. One or more of the plates in the are contacts O C are connected by means of a contact board wit-h the locking magnets R R respectively. The whole arrangement is such and the parts are relative to one another in such a manner that the rubbing contacts 0,, 0 -con1e into contact with the plate which bears the same number as the perforation through which the brushes V or V is in meshing contact. feed device there is arranged further, .a broad toothed wheel D which serves to rotate the counting pinions E E E in the adding operation. This toothed wheel I) has nine teeth which are so arranged in're'- lation to the counting wheels that immediately one of the contact brushes T T and: T comes exactl bers on the car the correspondingly numbered tooth of the wheel D will be situated exactly in front of the point of its engagement with the adding pinions. t

The improved machine comprises further an' electric battery K, locking magnets. and; clutches hereinafter describe If, for instance, it is desired to select all the engineers in a certain town and at the same time add their respective incomes to-' ether and it is assumed that engineers in this town are represented by the numbers 7 and 3 in the first and second columns all the cards are perforated in the first two particulars as shown. The three columns on the right of the card may contain, for'instance,

On the same axis .as the opposite one of the numthe incomes stated in thousands," hundreds and tens of dollars. stance, $6,470.

As the card is being .fed in the direction of the arrow the contact brush V will come through the hole 7 into contact with the In this case, for indrum and thus close a circuit extending from the battery K through the axle, the contact this sheet plateof theigroup 01 which is I designated 7 the locking magnet R brush V,, the; drum, and thus backhas been released.

. this means contact to the battery. By this means the locking magnet R releases partly the contact R n the electric circuit for the counter, but in such manner that the contacts R and G can be closed only after the locking magnet B, 'By a further feed of the card' he brush V in passing over the hole 3 in the'card closes the circuit extending from the battery through the axle, the contact 0 the contact plate of the group G which is designated 3, the locking magnet R and again through the brush V the drum, and thus back to the battery.

themagnet R releases a locking hook 'and only now can the arm B drop and close the contact G.

First, the brush T comes through the hole 7 into contact with the periphery of the drum thereby closing an electric circuit extending from the electric battery through the axle, the rubbing con- B, the contacts.

the adding wheel E which is rotatably mounted on the end of a spring- -actuated lever, -No. 7 of the mutilated toothed Wheel D comes into mesh with tooth which consequently rotates the adding wheel E in the forward direction to the extent of 7 teeth.

The lever is pivoted'about a shaft P.

- On this shaft is also rotatably mounted an other adding wheel 0 similar to E to which the number ring S is attached.

The toothed wheel Dis provided with a cam L which resets the lever N behind the i 'stop Q on the armature M since this is held against the lever N by means of a spring and thus takes the wheel E out of mesh with the mutilated-wheel D. The wheel .E is now ready to be engaged again with the teeth on D.

'The wheels E, and E, are mounted and operated in the same manner .asE

Similarly the addingpinions E will be rotated forwards to the extent o'f l and 6 teeth respectively. At each revolution of the drum the adding wheels. are

. brought out of mesh, whereupon the. number beingcarried forward is added in the same way as in ordinary adding machines.

Below the feed drum there is provided a flap (not shown) which opens at the same time as thecontact arm R. which turns'down to the screw terminal G.- By the opening of this flap all the cards that. have effected a release of the magnets R and R are separated out.

readily understood that all those cards that have their perforated selected ing more than two figures by simply providing a corresponding number of locking magnets and selecting arcs. The locking magnets must be so constructed that immediately all the magnets have been released, the machine will then only be able to register one or more statistical data for the card groups which have produced the release of the magnets. In' the same manner a plurality of rows of counters may be provided for effecting the simultaneous addition of a plurality .of particulars on the cards.

By connecting the locking magnets with a plurality ofcontact plates on the selector arcs O 0,, it is possible by'means of a series of selector brushes to separate out and register a plurality of groups of cards. For instance, if it is desired in addition to group '73 to separate out and register also groups 74, 75, and 76 the operator has merel toconnectthe contact plates 4:, 5 and 6 o the are C with the magnet R so that the'locking.

pawls of this magnet will be released, also all cards whose numbers 4, 5 and 6 are per-- forated in the same column in addition to being released by the cards that are perforated at No. 3.

In the example here given the counter is employed in combination with the selector mechanism. It is however obvious that the counter can be used by itself.

Vllhat I claim is 1. A machine for registering statistical and like particulars-comprlsing a movable carrier'for cards perforated according to the particulars to b'e registered, aplurality of brushes resting on sald carrier, electrical (Trcuits including saidcarrier and brushes, an adding mechanism comprising a mutilated toothed wheel having nine teeth moving synchronously with the carrier, a plurality of' toothed adding wheels, and an elec- L tr o-magnet associated with each of said add .ing wheels and included 1n said circuits,

said electro-magnets being adapted to be energized to bring their respective adding wheels into mesh with the mutilated toothed .wheel so as to be rotated through numbers of teeth corresponding to the numbers rep- -resented by the perforations in the card through which the carrier and brushes come into contact to complete the circuits of the respective magnets.
