Abstract
Abstract A toy which enables a child to draw pictures by remote manipulation of a writing instrument, including a frame for supporting a sheet of paper, a marker holder for holding a writing instrument over the paper, and a pair of knobs which can be turned by a child to move the holder in each of two perpendicular directions over the paper. The marker holder is mounted for sliding in the ''''X'''' direction on a carriage and the carriage is mounted to move in the ''''Y'''' direction on the frame. When a ''''Y'''' knob is turned by a child, it rotates a pulley which moves a cord that is attached to the carriage to move it in the ''''Y'''' position. When an ''''X'''' knob is turned, it rotates a square shaft, and a pinion rotatably mounted on the carriage and coupled to the shaft then moves a rack on the marker holder to slide it in the ''''X'''' direction. A program in the form of a strip with rows of letters and numbers defining ''''X'''' and ''''Y'''' locations to which the holder can be moved, defines a picture that can be drawn by a child.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
207 words
A toy drawing machine comprising: a frame having a paper-holding region; an X knob rotatably mounted on said frame; a Y knob rotatably mounted on said frame; a shaft of non-circular cross-section rotatably mounted on said frame and coupled to said X knob to be rotated by it; a carriage mounted to slide along said frame parallel to said shaft; pinion means engaged with said shaft to be rotated by it and coupled to said carriage to move with it in a direction parallel to said shaft; an elongated holder member slidably engaged with said carriage to move with it while enabling sliding perpendicular to the length of said shaft, said holder member including means for holding a writing instrument to move it over said paper holding region; rack means on said holder member, said rack means coupled to said pinion means for sliding said holder member in response to rotation of said pinion means; a drive pulley rotatably mounted on said frame and coupled to said Y knob to be rotated by it; and cord means extending in an elongated loop parallel to said shaft, one end of said loop extending about said drive pulley, and said cord means fixed to said carriage to drive it.

A toy drawing machine comprising: a frame having a paper-holding region; an X knob rotatably mounted on said frame; a Y knob rotatably mounted on said frame; a shaft of non-circular cross-section rotatably mounted on said frame and coupled to said X knob to be rotated by it; a carriage mounted to slide along said frame parallel to said shaft; pinion means engaged with said shaft to be rotated by it and coupled to said carriage to move with it in a direction parallel to said shaft; an elongated holder member slidably engaged with said carriage to move with it while enabling sliding perpendicular to the length of said shaft, said holder member including means for holding a writing instrument to move it over said paper holding region; rack means on said holder member, said rack means coupled to said pinion means for sliding said holder member in response to rotation of said pinion means; a drive pulley rotatably mounted on said frame and coupled to said Y knob to be rotated by it; and cord means extending in an elongated loop parallel to said shaft, one end of said loop extending about said drive pulley, and said cord means fixed to said carriage to drive it.
Claim 3
Dependent Claim
69 words
The toy drawing machine described in claim 1 wherein: said frame includes an elongated housing portion extending above the level of said paper-holding region; and said X and Y knobs are rotatably mounted on opposite sides of said housing portion, the axis of rotation of each of said knobs forming acute angles between 20* and 80* with imaginary lines that are normal to the plane of said paper-holding region.
Claim 4
Dependent Claim
48 words
The toy drawing machine described in claim 1 wherein: said means for holding a writing instrument is located at one end of said holder member; and including pointer means mounted at an end of said holder member opposite said instrument holding means, whereby to enable copying of drawings.
Claim 5
Dependent Claim
47 words
The toy drawing machine described in claim 1 including: a program in the form of a strip containing coordinate designations; and means on said frame for holding said program including walls defining a slot for closely receiving said strip program while allowing it to be slid therethrough.
Claim 6
Dependent Claim
115 words
The toy drawing instrument described in claim 1 including: a first scale mounted on said holder member to indicate the X coordinate position thereof, said first scale including a series of number coordinates; a second scale mounted on said frame adjacent said carriage normal to said first scale to indicate the Y coordinate position of said holder member, said second scale including a series of letter coordinates; and a strip program having a plurality of rows of coordinates, designating steps of a program, every other one of said plurality of rows beginning with a letter and rows therebetween beginning with a number, and each of said plurality of rows containing an odd plurality of coordinates.
