9 Claims. l
This invention relates to improvements in card files. More speciiically, it relates to a mechanism by which suitably coded cards can be selectively withdrawn from a le of cards.
l-leretofore an apparatus known as an Electroile or Selectograph and described in patents numbered 1,846,779; 2,002,807; and 2,002,808, issued to John W. Whitson and dated February 23, 1932; May 28, 1935 and May 28, 1935, respectively, has been used to facilitate the ling of cards and withdrawing of selected cards from the le.
Briey, the apparatus comprises a iile which has means for supporting the cards on edge transversely of the le and in groups which are spaced longitudinally of the le. Each card on its lower edge is provided with a row of spaced projections. The cards are individually coded by clipping oir certain of the projections. The cards also have attached to one edge an iron strip or armature.`
When it is desired to select a certain card from the le, the le is placed on a machine which has a plurality of bars arranged to enter the notches between the projections; keys are operated in accordance with the code of the desired card and the corresponding` bars are raised into the notches. An electro-magnet is disposed adjacent the line of iron strips and when this magnet is energized with the bars raised, the card, which has had the projections on the side of the raised bars away from the magnet clipped oi, will be pulled laterally by the force exerted on its armature and will thus be identified and can be manually removed from the iile. All the other cards are held in place by the projections which, being intact, engage the raised bars.
The selected card may be replaced anywhere in the file, since it will respond to the magnet from any position in the le.
Certain dirculties have been. experienced with such apparatus in that the electro-magnet was nxed and in spaced relation with the armatures so that the pull on the card armatures Varied with atmospheric conditions. Further, there was a tendency for all of the cards to tilt if the pull was strong, so that identiiication of the selected card was difcult. Other troubles were experienced which are cured by the invention herein disclosed, which has for one of its objects the provision of a permanent instead of an electro magnet. This eliminates any need for electrical connections and increases the range of utility of the device.
Another object of the invention is the mounting of the magnet so that it can be moved into cont inserted in the machine.
tact or at least very near the armatures of the cards so that the eiect of the air gap s substantially eliminated.
A further object of the invention is to provide means for holding the cards, not corresponding to the code, in place while the desired card is being selected.
Still another object of the invention is to pro# vide a magnet actuating mechanism which will both withdraw the selected card laterally and tilt it upwardly about one corner, thus rendering its identification positive.
Yet another object of the invention is to provide an apparatus which will withdraw from the le only thecard which corresponds to the code set up by the keys and bars.
These and other objects Will become apparent from a study of this specification and the drawings which are attached hereto and are made a. part hereof and in which:
Figure l is an end view of the selector apparatus and the card file, showing the cards in normal position in the iile and the magnet in position adjacent the armatures.
Figure 2 is an end view of the apparatus of Figure 1, showing the magnet retracted and the selected card displaced.
Figure 3 is an elevation of the apparatus of Figure l, viewed from the `right of that iigure, but showing the card iile in an elevated condition 4with respect to the selector apparatus.
Figure 4 is an elevation of the shaft supports taken on the line .4 4 of Figure 3.
Figure 5 is an elevation of the rack and pinion mechanism taken on the line 5-5 of Figure 3.
Figure 6 is an elevation of the magnet, support and fulcrum mechanism taken substantially on the line -B ofFigure 3.
Referring now to Figure 1, the numeral l indicates a base member which hasa side wall 3 bent at 5 to receive one side of a card file. A second side wall l is formed with an outwardly directed flange or magnet guide 9. The side wall 3 is formed with a ledge I il for `supporting the left ends of the cards (Figures 1 and 2) as 'the ille is The ange 9 is disposed to' support the opposite ends of the cards. The rods 63 of the lilenormally support the cards but, as the le is inserted in the machinatthe cards come to rest with their ends supported on ledge I0 and ange 9 while the le is further l'owered until the rods 63 are supported on the members I2 of the machine.
