INVENTOR ATTORNEYS- Patented Dec. 5, 1939 PATENT OFFICE 2,181,995 cam) S'TACKING DEVICE Hermann Keil, Berlin-Lankwitz, Germany, assignor to the firm Deutsche Hollerith Maschinen G.'m. b. H., Berlin-Lichterfelde, Germany Application October 15, 1938,. Serial No. 235,283 In Germany May 20, 1938 3 Claims. (01. 271-88) The present invention relates to card depositing devices utilized in card controlled machines such as tabulating and sorting machines controlled by cards with holes or other index marks,

wherein the card after having passed through the machine is diverted above the' depositing pocket by an inclined surface and drops freely into the pocket immediately after leaving the card feed rollers. 1

In order that in such devices the cards are properly stacked it is necessary that the distance of the free dropping of the cards be as short as possible,- and moreover, always constant independently of the height of the card stack which is in the pocket. The bottom of the pocket is,

therefore, guided so as to be movable up and down and is usually urged upwardly by a spiral spring. As the cards drop into the pocket the card stack will drop downwardly against the w tension of the spring. The resiliency of the spring is so selected that with each newly arriving card a downward movement of the bottom of the card pocket equivalent to the thickness of the card will take place so that the top of the card stack will assume the same position thus causing the distance each card drops into the pocket to always be thesame. In order toinsure that the downward movement of the bottom of the card takes place immediately with the recep- 30 tion of the cards first received, the friction which the card pocket bottom encounters in its guide must be very low because this friction must be overcome by the weight of the first few cards fed into the pocket. 3 It is a vwell known construction, in depositing arrangements of the type referred to, to fasten the card pocket bottom withits lower side to a tube in which a spiral spring is arranged and which tube is guided in another fixed tube. The latter tube must, therefore, be arranged below the 4 lowermost part of the depositing pocket. This arrangement complies with the requirement of,

a guidance with very low friction, however, it requires a construction of the machine which has 4 the disadvantage that below the depositing pocket a comparatively great space must be provided for the long guide tube and, as a rule, a machine frame with long supporting legsis required by this construction.

5 According to the present construction the card pocket bottom is arranged as a carriage runningup and down onone side wall of the card pocket and is drawn upwardly by a tension spring also arranged at the side and close to the plane of the 5 rollers. The arrangement is such that in spite of the restriction of only one spring and two pairs of rollers tilting or jamming of the carriage in the pocket is impossible. The novel arrangement results also in little friction in the guidance of the card pocket bottom and compared with 5 the known arrangement, above described, it affords the advantage that it does not require arify great space below the pocket and may, therefore; be incorporated in machines having a frame without legs so that it may be placed on 10 any table with the base plate restingthereon. Such an arrangement is particularly desirable when comparatively small machines, such as small sorting machines, are provided and have only'two or three pockets. Such machines are 15 used when the sorting of a stack of perforated record cards according to two or three characteristics is required. For instance, if the cards with a certain designating perforation are to be assorted from the stack of cards, the cards 20 withthe desired designatingperforation will be fed into one pocket and all remaining cards into the other pocket. The same operations will take place if a separation according to perforated and imperforategcards is required. Asserting may also be effected in a known manner so that all cards having a perforation within certain numerical limits such as, for instance, 'cards having a perforation representing numbers between 1200 and 1400 are passed into one pocket while all cards with a lower number representing perforation are passed into a second pocket and the cards with a higher number representing perforation are passed into a third pocket. Therefore, in such types of machines only three card pockets would be provided. In these and similar types'of machines comprising a sorter with few sorting pockets the improved andnovelcard depositing arrangement may be incorporated although the particular advantages described are 0 by no means restricted to such types of .ma-' chines.

One embodiment of the invention is shown in the-drawings and preferably illustrated in connection with a sorting machine having only two sorting pockets.

Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present in the embodiment of the invention described and shown in the accompanyingdrawings whetherwithin or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.

Fig. 5a-is a plan view of the depositing pockets. Although the improved arrangement may be appliedto card controlled machines of different types it is' preferably shown in Fig. 1 in connection with a machine for sorting perforated record cards. This machine has only two sorting pockets and serves for the assorting of cards, as

has been already mentioned. The machine rests upon a table In. The cards to be sorted are inserted in a supply hopper II.

I5 is reciprocated by a motor l2 by means of a worm gear l3 and a-crank drive l4 causes the picker IE to feed for each revolution of the crank one card to feed rollers 5 which are also driven by the motor. The card then passes beneath the analyzing device I! and further to the.

feed rollers l8'and depending upon the position of the deflector l9 it will pass either into the pocket or to the feed rollers 2| which feed the When the "card is fed to the pocket '20 it is deflected downwardly by the, movable deflector I9 and when the card is fed to the pocket 22 it is deflected by the stationary deflector sheet 23. If the simplest type of machine is assumed in which a card separation shall take place according to perforated and mimperforate cards, upon the analysis of a per- -to be raised and heldtemporarily in this position so that the card fed by the rollers l8 will be l9 into the pocket 20. Thus all perforated cards'will drop into the right hand pocket 20 (Fig. 1). Upon the passage of the imperforate cards the magnet 24 will not be card receiving carriage (Fig.2) is provided, generally indicated by numeral 40 and upon the upper incl ned surface 25 of the same the cards will .be stacked. In Fig. 1 the right hand carriage 40 is shown in its lowermost positio' with the pocket 20 filled, and the left hand carriage 40 is shown in nearly the uppermost position and which position is taken after a few cards have been dropped into the pocket 22. If sorting takes place according to perforated and imperferate cards, as has been assumed above. the cards in the right hand pocket are the perforated cards and those in. the left hand pocket are the im- The movable card depositing-carriage 25 has triangular side walls 26 which carry the. pairs of.

The lower portions of the side walls 26 are'interconnected by the rod The card picker- The triangular side 31 to the middle of which a tension spring 32 is connected and the other end of said spring is fastened to a spring stud 33 carried by the fixed wall 30 of the card pocket. A wall 34, which is the fixed side wall of the same pocket, is also provided with slots 36 (Fig. 1) receiving portions of the side walls 26 of the card depositing carriage.

This arrangement prevents cards from jamming between the carriage and the card pocket walls.

The assembly of card depositing carriage, card pocket wall and tension spring maybe best seen in Figs. 5 and 5a. The upper rollers 21' roll on the outside of the fixed wall 30 and the lower 1 rollers 28 roll on'the inside of the card pocket wall 30 so thatjthe force acting in counterclockwise direction and resulting from theweight of the cards, as well as from the tension spring, will merely cause the card pocket carriage to receive a translatory movement. The carriage will, therefore, move downwardly guided by the walls 30"and 34 as soon as cards are deposited thereon so that their weight will overcome the tension of the spring 32.

The sideward movement of the carriage'is prevented by the guide slots 29 and 36 of the

plates

30 and 34, respectively, receiving the side walls 26 (Figs. 2 to 4).

It is, therefore, possible to fasten the spring to the lower end of the-carriage, namely, to the pin 31 and to make use of the complete length of the spring.

The side wall 30' of the pocket 22 is assembled together with the side wall 34 of the pocket 20 by overlapping bent lips (Figs. 5 and 5a) which are fastened together by any suitable means and thesetwo side walls form together with'the carriage 40 and the spring 32 a unit which is fastened to the machine frame. If more than two dep'ositin'g pockets are provided this unit arrangement may be provided for any desired numher of pockets.

In order to decrease the. height of. the machine the base plate 4| (Fig. 1) has a recess in which the lower part of the carriage can enter (Fig. 1)
