Patented Nov. 24, 1931 UN13-15131),STATiIEi S PATENT orrlcs I LEONARD A. rnueimj or scum BEND, INnIANA" EDUCATIONAL DEVICE Application filed February 5, 1930. Serial No. 426,164.

Figure 2 is a front View of the overlapping indicia bearing discs illustrating the manner in which they are mounted on the card.-
Figure 8 is a top plan view of thediscs and Figure 4 is a fragmentary top plan view on an enlarged scale to illustrate how the discs are mounted on the card for movement-without interference with each other.
Figure-5 is a fragmentary front view-i1 lustrating. the manner in which the device may be used to state mathematical problems. Referring to the drawings, thenumeral 10 designates a "card, preferably formed of strong, heavy cardboard, on which j are mounted in overlapping reation discs 11, 12, 13, 14, 15and 16, all of equal size; however, it is to be understood that theuse of six discs in'the drawings is merely for the, purpose of illustration and a greater or smaller number of these discs maybe used as desired, a The preferably spacedapart adistancesubstantially less'than the radius of said discs, said eyelets being disposed adjacent the. upper end 35 of the card inaligned position. The alternate discs 11, 13 and 15, and 12, 14 and 16 are mounted'onopposite sides of thecard, the
discs 11,13 and 15 being mounted onthe front of the card, as shown. and'thediscs 12, 14 l and,16:on the back of the card. Between the eyelets'mounting the discs 12 and 13, andbetween the eyelets mounting the discs 14 and 15, slots 18 and 19, respectively are cut'in the card, said slots extending from the up- Der edge of the cardito a point adjacent the lower edge of the card and below the upper edges of the adjacent discs. The upper portion of the card is thus formed into two outer vertically extending arms 20 and 21, carrying parallel to arm 22; and the right hand portion of disc 12 carried by the back of arm 20 and the left hand portion of disc 13 carried by the front of arm 22 are thus adapted to be inserted through slot 18, and the right Y hand portion of disc 14 carried by the back of arm 22 and the left hand portion of disc 15 carried by the front of arm 21 are adapted to be inserted through slot 19, all as clearly shown in Figure 4. The end cards 11 and 16 remain entirely on the front and rear sides of the card, respectively. The upper right hand corner of the arm 21 of the card is cut away to a point below the level of the eyelets 17 and inwardly to a point adjacent the outer right periphery of disc 15, as shown in Figure 2, to permit the center of the portion of the disc 16 projecting beyond the disc 15 to be' seen from the front of the card. Thus it will be seen that the discs,though but slightly spaced apart, are all mounted on the card for'independent unimpeded movement, and the right hand projecting portion of each card is visible from the front of the card.
Each of said discs has suitably impressed thereon in a circle concentric of the cardand slightly spaced from its outer periphery a plurality of characters, which preferably comprise the alphabet, the digits and any other characters desired, such as addition, subtraction, multiplication, division and equals signs, said circle of indicia also preferably having a blank space therein. The circle of characters is disposed on said cards in a position whereby said characters will be visible beyond the outer periphery of the adjacent disc thereabove when at the right of the eyelet mounting the disc and in horizontal alignment'with said row of eyelets.
The card and discs are disposed in an open ended sheath or envelope 23 preferably of a size permitting the upper edges of the discs to project therefrom whereby they may be engaged by the fingers of the user for rotation and manipulation as desired, each in dependently of the others. In the sheath 23, in alignment with the eyelets 17-when the card is mounted therein, is formed a sight opening 24 of a width sufiicient to permit one character of each disc to be seen therethrough at one time, and of a. length and location to permit the. projecting portion of the indicia circle of each disc to be seen therethi ?ough.
It will thusbe seenthat by mani i ulation of the discs any word or combination of letters or digits comprised of six characters may be brought into alignment in registration with the sight opening, and that, by the insertion of blank spaces in the indicia circles, words and character combinations of less than six characters may be brought into registration with the sight opening. It will also be seen that with the use of mathematical characters it is possible to state mathematical problems with the discs, as illustrated in Figure 5. A further method of using the device is to place in registration with the sight opening a base, such as at on the second and third discs 12 and 13, and then by manipulation of the dial 11 on the left bring into registration with the sight opening various initial letters which combine with at to form words, such as bat, cat, fat, hat, etc., the use of which words, and others similar thereto, in a similar manner being a common method of teaching children to'read. It is thus evident that the device as an educational device has a very wide range of possible usage and adaptability. V
Thus, considered structurally, the device comprises a plurality of equal sized, indicia bearing discs rotatably mounted at their centers on a card in overlapping relation, with a portion of said discs projecting through slots in said card in a manner to permit movement of each disc independently of the others, said card and discs being disposed in a sheath having a sight opening through which one character on the portion of each disc projecting beyond its overlapping adjacent disc may be'seen, said discs being manipulable to place in registrationwith said opening any desired combination of the characters on said discs.
The invention having been set forth, what is claimed as new and useful is:
1. In an educational device, a card, said card having a plurality of slots therein forming arms at one side of said card, and a plurality of overlapping, indicia bearing discs rotatably carried by said arms. said discs being alternately mounted on the opposite sides of said card whereby portions of adjacent discs mounted on adjacent arms may extend through the slot between said arms.
2. In an educational device, a card, said card having a plurality of slots formed therein,and a pluralityv of overlapping, in-
dicia bearing discs rotatably mounted at their centers at slightly spaced points on said card, alternate discs being mounted on the opposite sides-of said card whereby a portion of the discsmounted on the opposite sides of each slot may extend through said slot and two discs may be mounted between adjacent slots, each of said discs being adapted to have r0tative movement independent of the other.
3. In an educational device, a card having a slot formed therein, a plurality of discs rotat ably mounted on said card at points spaced apart less than the radius thereof, and a sheath having a sight opening and adapted" I to encase said card and discs, said discs being alternately mounted on opposite faces of said card whereby the adjacent portions of the discs mounted on the opposite sides of said slot may extend therethrouqh to expose a portion of each disc at said sightopening.
4. In an educational device, a card'having a slot formed therein, and overlapping, indicia bearing discs rotatablv carried by said card, the discs adjacent said slotfon opposite sides thereof being mounted on opposite faces a of said card whereby the adjacent portions of said discs may pass through said slot.
5. In an educational device, a card having a slot formed therein, and a plurality of in dicia bearing discs rotatably carried byrsaid card in overlapping relation, alternate discs being mounted on-opposite faces of said card wherebythe adjacent portions of the discs mounted on the opposite .sidesof said slot may pass through said slot, said card being cut away to expose a portion of the indicia of the end disc mounted on the back face of said card.
In testimony whereof I afiix my signature.
