srncrrrcA'rroN' forming part of Letters Patent No. 736,140, dated August 11, 196e.

Application led March 13,1903. Serial No. `147,570. (No model.)

T @ZZ whom t may concern:

Be it known that I, MARY EMMA NIoHoLL, a citizen of the UnitedStates, residing at `East Oakland, in the county ot Alameda and State of California, have invented certain new and useful Improvements in Memorizers, of

which the following is a specification.

My invention relates to a mechanical memorizer for impressing-upon the memory the order in which occur the dierent portions of the subject-matter of a book.

. One of the principal uses kof the inventionA is to assist children in learning the order of thebooks of the Bible, and I have therefore illustrated myinvention as used for this purpose.

` `My invention therefore resides in the novel y construction, combination, and arrangement of parts for the above ends hereinafterfully specified, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front view of the device'. Fig.` 2 is a rear view. Fig. 3 1s a vertical section of the same. l

Fig. 4 is a detail View of one ofthe strips.

p j Referring to the drawings, l represents the main body of my device which consists of a sheet of stiff cardboard or the like Ahaving drawn or printed thereon the representationI of an open book-as, for instance, the Bible. In those portions of the cardboard on which are represented the edges of the leaves of the` book (shown in the drawingsat 12) are cut slits. 3 andthrough said slits slide index-strips L These strips are made of celluloid or* other suitable m'ateriaL'and upon their outer ends are printed the names of the several books of The strips are also variously col' cred to represent the general character ot' thel contents of the said books-as, for instance, the books of the law may be colored blue, the historical `books red, the poetical books green, the prophetical books yellow. Inthe New Testament the Gospels are colored white, theEpistles are colored blue, the prophetical yellow, and the `historical red, The extent of outward movement of these strips is limited, and `I have herein shown the following contrivancefor limiting said movement, al though other devices for this purpose may be used. Each strip is slotted at its inner end, as shown at 6, and through said slots extend.

repeated trials to correct the error.

pins 7, which are securedzupon a vertical strip 8, secured upon the back of the cardboard. By reason of the engagement of said .other in regular order from'the outside inward. They may, however, as shown, be arranged in rows in any convenient number, so as not to overlap each other to an inconvenient extent. 4

In use the` soholarwill start with allkof the strips pushed in, so that the names of the books are concealed. He will then name the first-book of the Bible, Genesis, and will pull out the corresponding strip to ascertain whether this is correct. He will then in succession pullout the other strips, and will thus learn Whether he knows the names of the books in their proper order and at whatpoints he is in error, and will thus be enabled by t 'llhus he will beenabled to learn the order of the several books of the Bible in an easy and attractive manpner and Without Weariness` or discomfort.

While VI have herein shown the preferred formof my construction, I do not desire to be `limited thereto, but claim such proper equivalents as come within the essence and scope of my invention. Y

l'. In a device of the character described, the combination of a sheet of cardboard or the like, having'formed thereon a pictorial representation of an open book, said sheet having slits in such portions thereof as shownlthe -edges of the sheets of the open book, strips movable through' said slits, said strips having marked thereon the names of the portions of the subject-matter of the book which commence at the points'indicated byithe slits, and means for limiting the inward and outward movement of said strips whereby when the strips are pushed in the said names are concealed and when they are drawn out the 4names are exposed, substantially as described.
