|This instruction booklet describe the construction of two Meccanographs which are a development of those in MP138. Both produce patterns with up to fourteen peaks or sides, by gearing the table rotation and reciprocal motion so that one relates to the other by factors of two to seven. Once again the Schmidt coupling provides the means of driving the table rotation when the table is moving to and fro.
Either may be constructed from the largest Meccano Set (No.10) with a few extra parts. The Mark III is the simpler of the two. Instructions include Frame, Designing Table Support Cage, Schmidt Coupling, Pen Cam & Drive, Primary Drive, Table Rotation Gearbox, Designing Table & Rear Pen Support Transverse Motion (Optional), Pen Arm, Designing Table and operation. The Mark IV incorporates a more elaborate gearbox to allow table rotation speeds to be varied through five different ratios. Instructions include Frame, Primary Hand Drive, Pen Cams, Reduction Lay Shaft, Table Rotation Gearbox, Schmidt Coupling, Designing Table Support Cage, Transverse Motion drive, Cam, & Table Link, Pen Support Parallelogram & Arm Support, Pen Arm Drive Strips and operation
20 pages of text, b&w and colour photographs and parts list.
