Patented May 28, 1935 44 Claims.

This invention relates to improvements in card Illing and segregating apparatus of the type disclosed in my pending application for patent for card record apparatus led January 5, 1925,

Serial No. 663 which has since matured into Patent No. 1,846,779, issued Feb. 23, 1932.

One of the objects of the invention is to provide a card record apparatus of the character described which will'be comparatively simple as to construction and operation, compact, and Vinexpensive andv which may be operated to segregate the cards as desired, in a much more accurate and expeditious manner than has heretofore been possible with apparatus of this kind.

Another object of the invention is to provide a card record apparatus of the character described in which the cards may be easily, reliably and accurately segregated according to one or a plurality of characteristics of the cards by the simple expedient of pressing a button or similar operating member.

Another object of lthe invention is to provide apparatus ofthe character described with which a plurality of diiering methods of segregating the cards may be carried out without necessitating any changes in the construction of the apparatus, and without complicating the method of operation thereof, thereby making the apparatus adaptable for various uses and for various businesses wherein card record systems peculiar to the particular business, are employed.

A further object of the invention is to provide an apparatus of the character described which will provide for the proper housing of a greater number of cards and a more rapid, reliable and accurate segregation of said cards in a smaller and more simply constructed apparatus than has heretofore been possible in this art.

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the claims hereto appended, it being understood that various changes in the form, proportion, size and mino:` details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Fig. 12 is a diagrammatic view of the electrical circuit for the magnets and circuit closers.

The embodiment of the invention shown in the accompanying drawings comprises a casing I, made up of acard compartment 2, a mechanism compartment 3, and a keyboard 4. Cards 5 are supported on shelves 6 and 1, at the sides and extending beneath card compartment 2'. A plurality of nger keys 8, lettered A, B, C, etc.; are fixed to horizontal selecting bars 9 by rivets 31 and extend above the keyboard 4. The bars 9 pass through vertical slots I0 and II in the casing I and are adjustably supported by rods I2, the bars 9 having inclined slots I3, through which rods I2 pass. When any one or more of the finger keys 8 are operated the bar or bars 9 operated by the key or keys will move into upper or selecting position as shown in dotted lines Fig. 3. Springs I4 fastened to the casing I by screws 38 act to hold the bars 9 in selecting position said springs abutting the ends of said bars when the latter are in up position as shown in Fig. 3 in dotted lines. The rods I2 are secured at their ends as at Il to the/upper pole pieces I8 and I9 of electro-magnets I5 and I6. Electro-magnets I5 and I6 are fastened by screws 39 to the casing i, with their upper pole pieces I8 and I9 at opposite sides of card compartment 2 and the pole pieces extend the full length of the card compartment.

Lifter bars

20 and 2| are yoked together by a Ushaped piece 22 and have an operating key 23 secured thereto. 'Ihese bars 29 and 2I pass through

vertical slots

24 and 25 in the casing I and have inclined slots 2 I through which the rods I2 extend.

On the lower edges of the cards 5 are a plurality of spaced lugs 32, corresponding in number and position to the bars 9. Near the ends of the cards at their lower edges are slots 33 that receive the bottom members 3I of the carrier 29 when the carrier is lifted to remove the cards from the card compartment. The lugs in this instance on the front card shown are lettered A, C, D, and G, to correspond.I with letters on the finger keys 8.

The cards 5 are of a lesser width than the inner width of the compartment, to permit sidewise movement of the cards in the compartment.

For the purpose of illustrating one use of the apparatus of my invention, the lugs 32 are further designated Commercial, Savings, Safe Deposit, etc., representing various departments of a bank, it being desired to assort or select the cards under single indexings, groups or pluralities of indexings, etc.

There are several ways of indexing the cards, one by leaving on the lugs 32, as shown in Fig. 6; another by removing the lugs 32, as shown in Fig. 8, or a combination of the above ways may be used. The cards shown in both illustrations are listed Commercial, Safe Deposit, Loan and Foreign, or positions A, C, D, and iGl Fig. 9 shows a card before any of the lugs 32 have been removed. The cards can be made of magnetically attractive material, or as shown in Figs. 9 and 10, iight spring-steel pieces 34, having lugs 35, passing through slots 36 in the card, may be used. The card could also be made as illustratedl in my pending application entitled Card record apparatus, filed Jan. 5, 1925, Serial No. 663. In the present instance cards made of magnetically attractive material are used.

The cards Vcan be made to fit any size of file drawer and the carrier with its group of cards stored in same when not in use. Thus one selecting mechanism can be used with any number of cards.

Operation' Referring to Fig. 6, if it is desired toi select this card and all other cards listing all the indexings, Commercial, Safe Deposit, Loan" and Foreign, these indexings will be referred to by the lugs and keys representing them, to-wit: A, C, D, UG.

As shown in Fig. 4, a group of cards by means of the carrier 29 is lowered into a normal position spaced from the side walls of the card compartment 2, and the follower 30 is adjusted to allow free movement of the cards. The magnet I5 is then energized and all the cards are attracted and .moved out of the normal position -to the right against the pole piece I8 as shown in dotted lines.

`bar 9 into position for obstructing or holding all cards having lug A against movement to the left. 'I'he two-button switch 21 is then operated to close the circuit for and maintain energized the magnet I6. The cards' not having lug A will move thru the normal position to the left against pole piece I9. Key C is then pressed and key A moved to its down position or released by pulling forward on the finger key. The cards having lug A but not having lug C, will move to the left. Keys D and G are operated in turn. The cards thus moved to the left are clear of the lifting bar 2I and the recesses or notches 33 in said cards are moved into position to receive the lifting bar 29, when the latter is moved upwardly. Thus the cards remaining against pole piece I8 are thos'e having all of the lugs A, C, D, and G. The magnet I6 is then deenergized by operating the switch 21 and the key 23 is operated, moving the

bars

20 and 2| above the shelves 6 and 'I. The bar 2I will engage the lower edges of the selected cards which remain against the pol piece I8 and lift said cards upwardly whereas the bar 20 will engage the lower edge of said cards adjacent the other ends of the cards, these cards being at this time immediately over andl in position to be engaged and lifted upward by the

bars

20 and 2|. The other cards, however,.have the notches 33 in position to permit the bar 20 to move freely into the notches without lifting the cards. In this way the selected cards are pushed upward into the position shown in dotted lines in Fig. 5. A movement of all of the cards to the right as when the magnet I5 is energized, therefore disposes the cards in position to be pushed upward upon the upward movement of the bars 20 and 2 I, because said cards are normally positioned to one side of the lifting bars and would therefore not be engaged and lifted when said bars are moved upward. The follower 30 can then be tightened and the mass of cards lifted from the machine by means of carrier 29.

The selection was completed when magnet I6 was deenergized. Raising the selected cards above the mass is for convenience in referring to the names.

The card John Doe would also be selected with cards having lugs A or"A, C, or A, C, D, or C, D etc., when selection is made under these indexings. Several keys can be operated at once as keys A, C, and D, as when magnet I3 is energized, all the cards not having lugs in any of these (A, C and D) positions will move to the left. The card John Doe would be one of this selected group.

Referring to Fig. 4, when it is desired to select the cards having lugs A and C and not having lug E, key E is pressed and magnet I5 is energized, the cards not having lug E willmove to the right as shown in dotted lines. Referring to Fig. 5, magnet I5 is deenergized, key A is pressed, key E is released, magnet I6 is energized and the .cards not having lug A will move to the left. Key

C is pressed and key A is released, the cards not having lug C moving to the'left. Magnet I6 is then deenergized and key 23 operated as hereinbefore described. The card John Doe would be one of those selected.

Selection according to the method shown in my pending application entitled card record apparatus, filed Jan. 5, 1925, Serial No. 663, is made as follows: Referring to Fig. 4, the bars 9 are all moved to their upward position, the lugs 32 of the cards 5 fitting between the bars 9. It is desired to select the cards having any ofthe lugs A, C,. D and G. The keys A, C, D and G are moved to their lower positions, magnet I5 is energized and all the cards having lugs only at these positions will move to the right, where they can be elevated by operating key 23.

Referring to Fig. '7 a group of cards as shown in Fig. 8 is lowered into card compartment 2. It is desired to select all the cards having lugs A,

'and moving the cards not held to the C, Dand G removed, keys A, C, D and G are pressed, magnet l5 is energized and all the cards having lugs A, C, D and G removed will move to the right, where they can be elevated above the pack `by operating key .23. The card John Doe would be one of those selected.-

The card John Doe" would also be selected with cards having lugs A or A, C, or A, C, D, etc., removed, when selection is made under these indexings.

To select cards having any of the lugs A, C, D and G, removed, key A is pressed and magnet l5 vis energized, all cards not having lug A will move to the right. Key C is pressed and key A is released, magnet |5 is energized and all cards not having lug C will move to the right. Keys D and G are then operated in like manner and all cards not having lugs at positions D or G will have moved to the right, whence all the selected cards can be elevated by operating key 23. The card John Doe would be one of those selected.

It is desired to select the cards not having lugs A and C but having lug E. Referring to Fig. keys A and C are pressed and magnet I5 is energized, the cards not having lugs A and C will move to the right. Key E is then pressed and magnet I 6 is energized, those of the cards that have moved to the right, not having lugvE, will move to the left to the main assemblage of cards. Magnet I6 is then deenergized and the selected cards can be elevated by operating key 23.

The switch 21 is shown in detail in the diagram, Fig. 12. When the right-hand push button is depressed, the circuit is closed and the switch element stays in circuit-closing position,

due to the frictional engagement of the

contact pieces

24 and 24". When the left-hand button is depressed the circuit is opened. Electrical energy is conducted from one side of a suitable source indicated at 21', through a conductor 23', to one side of each of the magnets I5 and I6. From the other side of the' magnet I5, a conductor 22 leads to the switch 26, from which a conductor 20 leads to the other side of the source of electrical energy. A conductor I9 is connected with the conductor 20 and,

with the contact member 25. A conductor I8 is connected with the other side oi.' the magnet I6 and with the contact member 25".

Attention is called to the fact that the cards are divided into two groups when selection is made and that either or both groups lcan be regarded as the selected ones.
