Mechanical converter for converting rotary motion to reciprocating motion

A mechanical converter comprising a primary half-gear, a shaft, and a primary gear frame, the primary gear frame being made of a first and second rack, the first and second racks being in parallel and rigidly connected together, the first rack having a first toothed section and the second rack having a second toothed section,

• the primary half-gear having a toothed section for half of a circumference, being disposed inside the primary gear rack between the first and second tracks, engaged alternately with the first toothed section and the second toothed section;
• the primary gear rack configured to produce reciprocating motion in response to the alternate engagement of the primary half-gear with each toothed section.

A mechanical converter comprising a first, second, third, and fourth gear rack, a first and second shaft, a first and second corresponding gear, and a first, second, third, fourth, fifth, sixth, seventh, and eighth half-gear,

• with the first, third, fifth, and seventh half-gear and the first corresponding gear fixed to the first shaft and the second, fourth, sixth, and eighth half-gear and the second corresponding gear fixed to the second shaft;
• with the first and second half-gear alternately engaged to the first gear rack, the third and fourth half-gear alternately engaged to the second gear rack, the fifth and sixth half-gear alternately engaged to the third gear rack, the seventh and eighth half-gear alternately engaged to the fourth gear rack;
• with the gear racks being configured to produce reciprocating motion in response to the alternate engagement of the half-gears.
