Abstract
Abstract This invention is an apparatus to aid in the teaching of mathematics to children. It has a closed boxlike housing with a window to display the problems which are written on a sheet and attached to a roller mounted within the housing. The housing also has on its surface a member with a plurality of holes therein and pegs therefore and a member with a surface to receive indicia thereon for the student to formulate the problem''s answer. The apparatus has a plurality of indicators to be operated by the student upon correctly answering each problem, and a sensesindicating system operable upon proper manipulation of the indicators.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
146 words
A mechanical apparatus to aid in the teaching of mathematics preferably to children, comprising: a. a substantially closed boxlike housing having a window means; b. means mounted within said housing adapted to receive and hold a sheet of paper or like material in position to view a problem on same through said window; c. a member attached to said housing having a plurality of uniformly positioned holes therein adapted to receive pegs and a number of pegs therefor; d. means having a surface attached to said housing and adapted to receive indicia; e. a senses indicating system attached to said housing, said system having a plurality of indicators and means to connect same to a source of power; and f. said housing having other window means to display answers on said sheet of paper or like material upon operation of a window-opening means normally covering same.
Claim 2
Dependent Claim
146 words
A mechanical apparatus to aid in the teaching of mathematics preferably to children, comprising: a. a substantially closed boxlike housing having a window means; b. means mounted within said housing adapted to receive and hold a sheet of paper or like material in position to view a problem on same through said window; c. a member attached to said housing having a plurality of uniformly positioned holes therein adapted to receive pegs and a number of pegs therefor; d. means having a surface attached to said housing and adapted to receive indicia; e. a senses indicating system attached to said housing, said system having a plurality of indicators and means to connect same to a source of power; and f. said housing having other window means to display answers on said sheet of paper or like material upon operation of a window-opening means normally covering same.
Claim 3
Dependent Claim
93 words
The mechanical apparatus as described in claim 1, wherein: a. said means to hold a sheet is a roller means rotatably mounted within said housing behind said first-named window means; b. said roller means has an attached crank member extending from said housing; c. said roller means has a slot therein to receive and hold said sheet of paper or like material substantially near its outer surface; and d. said roller means and said window means is positioned on the normally upper rearward portion of said housing having said window means facing forward.
Claim 4
Dependent Claim
111 words
The mechanical apparatus as described in claim 1, wherein: a. said member attached to said housing has a plurality of holes therein and is positioned on the normally upper surface of said housing in the central portion thereof, joins the lower portion of said first-named window means, and generally slants downward forwardly to join said means having a surface adapted to receive indicia; b. said window-opening means is positioned generally parallel to and alongside said member on the surface of said housing; and c. said means having a surface adapted to receive indicia extends substantially across said housing, and is inclined slightly to the normally operable rearward portion of said housing.
Claim 5
Dependent Claim
70 words
The mechanical apparatus as described in claim 1, wherein: a. said senses indicating system is operable to stimulate the sensory perception of a person operating said apparatus upon manipulating all of said plurality of indicators to a positive answer position; and b. said plurality of indicators is positioned generally in a line substantially across and on the upward end portion of said means having a surface adapted to receive indicia.
Claim 6
Dependent Claim
43 words
The mechanical apparatus as described in claim 2, wherein: a. said housing has on its normally upwardly disposed surface said member having a plurality of holes therein which joins said window means and said window-opening means and said means to receive indicia thereon.
Claim 7
Dependent Claim
43 words
The mechanical apparatus as described in claim 2, wherein: a. said housing contains said senses indicating system which is operable to perception by the senses of the operator of said apparatus upon proper manipulation of said plurality of indicators located on said housing.
Claim 8
Dependent Claim
107 words
The mechanical apparatus as described in claim 1, wherein: a. said housing has a roller means operable by a crank to hold and display said sheet of paper or like material at said window means positioned on the normally rearward portion of said housing and facing forward; and b. said housing has said member having a plurality of holes therein alongside said window-opening means and joining said window means and said means having a surface adapted to receive indicia; and c. said apparatus has said senses-indicating system with said plurality of indicators operable to the sensual perception of the operator of said apparatus upon their proper manipulation.
