J. E. MCDADE MEMORIZATION DEVICE Filed Deo. 2l, 1925 Psaad sepa 13, 1927.
UNITED STATES .uns l11'. manana, or CHICAGO, rLLINois.
Application lled December 21, 1925. Serial No. 76,706.'
4 My .invention relates to memorization dev ices of the general type disclosed by .my application for Letters Patent of the United States Serial No. 41,608,1iled July 6, 1925,-
with the answer constituting the related ele? ment covered from view, the arrangement being such that in the normal use of the device the movement of the parts for the v presentation of a problem results -in the presentation of the previous problem and answer in associated .relationship opposite each other,`this result being attained, serving to verify the memory of the pupil, re-
gardless of whether or not there has been any doubt as to the pro er answer. It accordingly results that i lby any chance in such study an arroneous memory bond is formed tentatively, the error is detected and corrected immediately while the impression is fresh and before the bond' has had opportunity for complete establishment.
It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my objects are illustrated in the drawing and are hereinafterl specifically described. That which I believe to be new and desire to cover by Letters Patent is set forth in the claims.
In the drawing- Fig. 1 is aface view of an approved form of my device, partly broken away at one end;
Fig. 2 is a vertical cross-sectional view taken at line 2-2 of Fig. 1;
Fig. 3 is a face view of a modified form of my device, also partly broken away;
Figs. 4 and 5 are face views of still other modified forms of my device, also partly broken away; and
Fig. 6 is a face view of another form embodymg in a single device the forms of window shown in devices of Figs. 1 and 5.
Referring now particularly to Figs. 1 and 2, 10 indicates an open-ended envelope provided in one face with two windows 11 and 12, the former of which extends only part of the way across the face of the enve ope while the latter extends substantially clear ment still covered by the envelope.
across the face. Slidably mounted in' the envelope 10 there is a card 13 bearin a mass of data to be memorized, such ata being arranged in horizontal columns, with a question or problem in onel column and its answer oppositely 'disposed in the other column and so arranged that' the related elements, comprising a problem and answer, are at a glance`.discernible in close proximity to each other. rIhe card 13 may, of c ourse, be provided with any suitable data which it is desired to memorize, and such data arranged in columns may be applied to only one face or to both faces of the card for-use `alternatively in the envelope.
In use, the card 13 is inserted into the envelope from the right in Fig. 1 and moved toward the left until one element of the data in one column stands opposite the window 11 for presenting tov the eye the question or problem only, with the other relatedele- The pupil formulates his answer and then moves the card another step toward the left for presenting to the eye the next questionv or problem. Thismovement of the card toward the left for presenting the succeeding problem serves also to present to the eye through the window 12 the problem previously considered together with its answer, the problem and answer being presented in juxtaposition and segregated from all the remaining data on the card soy that the strongest sort of memory bond ma be attained by visualization if there has een before any possible question as'to what the answer is. If the pupil has been unable to formulate in his mind the answer, t-he segre-v gated showing of the problem and answer tends very strongly to form the desired memory bond. If an incorrect answer has been formulated, the pupil learns of his mistake immediately and a correction is effected before the impression has had an opportunity to become fixed. This correction occurs automatically by the movement of the card for presenting the next problem whether the pupil has or has not realized the necessity for checking his answer.
In `the form shown in Fig. 3, a single window 14 is used, such window being of a shape to present first the problem without disclosing the answer and then upon the succeeding movement of the card to disclose the problem and answer. Substantially the only difference in effect between the devices of Fi 1 and 3 is that in Fi 3 the problem an answer are not so comp etely segregated from the adjacent problem2 but the separation is suicient for attaining good results.
In the form shown in Fig. 4, a card 15 is substituted for the envelope, and a notch 16 is employed in lieu of the forms of window shown in Figs. 1 and 3. The eiect 1s the same, however, generally speaklng except `that in this construction the problem and answer as shown together are less completely se regated from the remaining por tions of t e card. In this construction, the card 17 is held vertically for study 1nstead of horizontally, being moved upwardly along the card 15.
In the form of device as shown in Fig. 5, the card 18 is held vertically for study but is moved downwardly through the envelope 20 19 which is provided with a suitable window 20 of the eneral type shown in Fig. 3.
In the orm shown in Fig. 6, a card 13 such as that shown in Fig. l is provided, slidable through an envelope 21 provided with windows 22 and 23 on one face for use of the card in horizontal osition, and provided in its other face wit a window 24 for use of a suitable card in vertical position in the manner illustrated in Fig. 5.
While I refer to use one of the forms of device as siiown in the drawing, it will be understood that I do not wish to be restricted to the particular form as shown except as the samev is hereinafter specifically claimed, inasmuch as it is evident that changes may well be made in thel form of device without departing/ from the spirit of my invention.
1. A memorization device comprisin a member bearing a mass of data arrange in columns with related elements oppositely disposed on a single face of the member, and' means for segregating from the remamin elements a single set of related elements an one of the elements of the adjacent set.
2. A memorization device comprising in mames combination a member bearing on one face a mass of data arranged as a succession of sets of related elements, and means for covering portions of the member adapted upon movement relative to the member to expose each ofthe several sets of related elements in turn and at the same time to ex ose in close proximity thereto one of the e ements 0f another set.
3. A memorization device comprising in combination a member bearing on one face a mass of data arranged as a succession of sets of related elements, and an open-ended envelop throu h which said member is movable longitu inallv, said envelop being provided with window means in one face through which each of said Sets of related elements in turn together with one only of the vrelated elements of the adjacent set is visible as the member is moved through the envelop.
4. Amemorization device comprisin a member bearing a mass of data arrange in columns with related elements oppositely disposed on a single face of the member, and a covering sheet provided with a single window past which said member is slidable and through which one element only of a set of related elements is visible and through which at the same time both related elements of the next adjacent set are visible.
5. A memorization device comprisin a member bearing a mass of data arrange in columns with related elements oppositely disposed on a single face of the member, and an o en-ended envelope through which said mem er is movable longitudinally, said envelope being provided with window means in each face thereof, through the Window means of either of which faces the sets of related elements are visible in succession, in
