Specification of Letters Patent.

Application filed September 3, 1915. Serial No. 48,870.

To all whom it may concern:

Be it known that .1, WILLIAM HENRY Ron- ERTSQN, a citizen of the United States, re

Toys, of which I- declare the following to be a full, clear, and exact description,

My invention relates to toys for educa tional purposes, and its mechanical construction i very similar to another invention' of mine for calculating purposes shown and de,

United States, SerialNumber 15,67 4.

The present invention is intended to stimnation .of parts. believed to be entirely new in the'toy art." 1 'o v As far asI am aware, anumber chart has never before been combined with any object resembling and representing a living creature which can be adjusted in relation to the chart. to perform computations, thereby suggesting the idea of a calculating. animal. With such a' novel combination, it is intended to interest the child and increasehis knowledge of numbers and number tables.

With these and incidental purposes in view, the invention consists incertain novel features of construction and combination of parts, hereinafter described'withrefer ence to the accompanying drawing'which accompanies and forms a part of this specification.

By reference to the chart shown on plate. A of the accompanying drawing, a series of numbers are'shown and above this a multiplication table. From thearrangement .of the numbers it can be seen thatthe product of any two numbers of the'series lies on animaginary line which is the perpendicular bisector of another such line I connecting the two numbers'of the series. Also, that this product is located above the slot in' plate A; at a height depending on the distance between the 'two numbers of the series.

-'Two members B and C are shown pivoted at D. To these are attached arms G and H pivoted respectively at, J and K-, and pivoted to each other at L, and'also to tail Mwhich has a slot in which are the studs ,Q and D,

both of which are riveted to head R. Pointers N and P are secured to the members brought closer together, the square hole in.

tail piece M is lowered and when the pointers are moved farther apart, the same hole is raised. v r

It will further be observed that the square hole in tail M lies on a line -which is a perpendicular bisector of the line co'nnecting the centers of studs E and F. There fore, the m otion of this hole satisfied the" conditions necessary to enable it to expose the product of any two numbers directly pointed at by the pointers. However, it'is foundboth by theory and experiment that for ,the regular arrangement of table as 7 shown, it is necessary that the three distances from the centers of stud J to the centers of studs D, L, and E be'equal each to each; likewise, for distances K D, L, and K F, whereithe letters represent the centers of the studs.

fit is evident by the apparatus de-' scribed, results could be found on an addition table and manytother kinds of tables as readily as on a multiplication table.

While the form of the invention herein shown and described is admirably adapted to accomplish the purpose primarily stated,

the claims which follow.

Patented June 27, 1916-.

' it is not intended to confine the invention to the form of embodiment hereindisclosed' What I claim "as new and desire to secure by Letters Patent of the United States, is: 1. In a toy, a chart having characters and a table of results, and a movable image of an animated creature having membersv adjustable to occupy various positionsrela tive to the chart in each 'of which positions characters",are designated and correspond ing results indicated.

2. In a toy a chart having a table of com:

putations and a series of numbers, and fa movable image of an annnated creature hav'-.

ing its members sueh asfllimbs adjustable to setto various positions relativeto the chart each of which positionstwo limbs of the lmag'e designate. each a numeral while an= other portion of the image indicates a resulting computation.

3. In a toy a chart having a series of characters and a table of results and an image of an animated creature composed of relatively movable parts, representing movable members of the animated creature two of which parts are pivoted together and admemberssuchas' arms, legs, feet and fingers,

two legs being pivoted together and adjustable to set at various positions relative to the chart in each of which positions the two feet designate each a number, while the fingers indicate the corresponding computation.

5. In a toy, a chart having various characters, and a movableqimage of an animated creaturehaving limbs, one of which is adjustable relative to the chart to set at various positions in each of which positions the limb and two other portions of the movable image indicate each a character there being three characters thus indicated each of which is a function of the other two.

. In testimony whereof I aflix my signature.

WILLIAM HENRY ROBERTSON.
