Abstract
Abstract An educational device including a base plate, a front frame having its left edge secured to the left edge of the base plate and a roll having paper thereon secured to the upper end of the base plate which roll is provided with a knob which a pupil may rotate with one hand while he pulls the free end of the paper downwardly between the base plate and the frame. The front frame is provided with an elongated opening for receiving a slide having letters or numerals stencilled therein. The slide maybe formed of a single piece or a plurality of connected segments which slide is held stationary within the frame by suitable means, such as by bevelled edges which engage bevelled edges at the openings in the front frame. The stencil is preferably formed of a plastic material having a thickness of 0.05 to 0.06 of an inch so that in forming letters or numerals, the pencil will follow a definite pattern. If desired, small numerals may be etched or printed upon the stencil adjacent each letter or numeral to show the progressive strokes of the pencil which are utilized in forming the letters or numerals.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
102 words
An educational device including a base plate, a front frame having one of its side edges secured to an edge of the base plate and extending over the base plate and terminating in a free opposite edge, said frame being provided with a longitudinal opening therein, means whereby a sheet of paper may be intermittently passed between the base plate and said frame, and a stencil slidably mounted in the longitudinal opening in said frame which stencil has openings of a type selected from a font of letters and numbers through which openings letter or numbers may be formed on said paper.
Claim 2
Dependent Claim
102 words
An educational device including a base plate, a front frame having one of its side edges secured to an edge of the base plate and extending over the base plate and terminating in a free opposite edge, said frame being provided with a longitudinal opening therein, means whereby a sheet of paper may be intermittently passed between the base plate and said frame, and a stencil slidably mounted in the longitudinal opening in said frame which stencil has openings of a type selected from a font of letters and numbers through which openings letter or numbers may be formed on said paper.
Claim 3
Dependent Claim
67 words
An educational device as defined in claim 1 including means for supporting the paper in the form of a roll on the base plate, means whereby the paper may be intermittently drawn from the roll so that its free edge may be passed between the base plate and the frame to receive letters or numerals written thereon by a pencil moved through the openings in said stencil.
Claim 4
Dependent Claim
99 words
An educational device as defined in claim 1 in which the edges of the opening in said frame and the edges of said stencil have engaging parts arranged in such relation to each other that the stencil is held in a stationary position within the frame and said paper being arranged on a roll on the upper portion of the base plate and having a free end portion which is intermittently movable downwardly between said frame and said base plate so that the same rows of letters or numerals in said stencil may be repeated written upon said paper.
Claim 5
Dependent Claim
135 words
An educational device as defined in claim 1 in which the frame has a second longitudinal opening therein below the first longitudinal opening beneath which the paper that has been passed below the first stencil may also be passed, a second stencil arranged within the second longitudinal opening which second stencil consists of segments in each of which a letter is formed, which segments in the second stencil are connected together to form an assembly in which some of the letters in the second stencil are the same as some of the letter in the stencil in the upper longitudinal opening which segments in the second longitudinal opening are so arranged that some of the stencilled letters in adjacent segments therein spell a simple word that Is suggested by letters formed in the upper stencil.
Claim 6
Dependent Claim
151 words
An educational device as defined in claim 1 in which each of the letters or numerals in the stencil is provided with narrow openings at their inner surface and corresponding in shape to a letter or numeral selected from a font of letters and numerals to receive at their inner surface the lead of a sharpened pencil, the point of which pencil engages paper interposed between the base plate and the frame with both side walls of the groove being bevelled outwardly from the narrow opening and said grooves being thick enough to receive the inclined wooden part of the sharpened pencil so that a pupil holding the pencil with its pointed end extending through the narrow opening in the groove at the bottom of the stencil will cause the pencil to follow the groove to make characters on the paper corresponding to the opening in the grooves in the stencil.
Claim 7
Dependent Claim
72 words
An educational device as defined in claim 5 in which the stencil consists of segments having parts arranged in interfitting relation with the frame and with each other in which each of said segments has grooves having narrow openings at their inner portion through which a selected letter or number of a font may be formed on paper arranged between and which is intermittently movable between the base plate and the frame.
Claim 8
Dependent Claim
29 words
An education device as defined in claim 5 in which the stencil is formed of a plastic material having a thickness of approximately 0.05 to 0.06 of an inch.
Claim 9
Dependent Claim
30 words
An educational device as defined in claim 5 in which the openings in said stencil are in the form of one or more cursive letters of the lower case type.
Claim 10
Dependent Claim
26 words
An educational device as defined in claim 5 in which the openings in the stencil are in the form of capital letters of the cursive type.
Claim 11
Dependent Claim

Claim 12
Dependent Claim
72 words
An educational device as defined in claim 5 in which the front frame has a second elongated rectangularly-shaped opening for receiving a stencil comprising a series of segment, each having an opening therein which when traced with a pencil on the paper beneath the segment forms a letter and in which the stencilled letters in the second longitudinal opening spell a word which is formed as a number in the upper stencil.
Claim 13
Dependent Claim
23 words
An educational device as defined in claim 5 in which the openings in the stencil are selected from one or more manuscript letters.
