Mechanical converter for converting rotary motion to reciprocating motion

A mechanical converter comprising a first and second gear rack, a gear wheel, a first and second half-gear, a third and fourth half-gear, a first and second shaft, and a first and second corresponding gear,

• a. the first shaft fixed to the first half-gear, the third half-gear, and the first corresponding gear, the second shaft being fixed to the second half-gear, the fourth half-gear, and the second corresponding gear;
• b. the first, second, third, and fourth half-gears each having a toothed section covering a portion of a circumference each;
• c. the gear wheal being toothedly engaged to the first and second corresponding gears;
• d. the first, second, third, and fourth half-gears each being configured to rotate synchronously, in the same direction of rotation, and in alternately toothed engagement with the gear rack so that only one of the first and second half-gears is engaged with the first gear rack at a time and only one of the third and fourth half-gears is engaged with the second gear rack at a time;
• e. the first gear rack disposed between the first and second half-gears and configured to produce reciprocating motion in response to the alternate engagement with the first and second half-gears;
• and
• f. the second gear rack disposed between the third and fourth half-gears and configured to produce reciprocating motion in response to the alternate engagement with the third and fourth half-gears;
• with the first and second gear rack oriented to operate in parallel.

A mechanical converter comprising a first shared gear rack, a second shared gear rack, a shared gear wheel, a first, second, third, and fourth half-gear, a first and second shaft, and a first and second corresponding gear,

• a. the first shaft fixed to the first half-gear, the third half-gear, and the first corresponding gear, the second shaft being fixed to the second half-gear, the fourth half-gear, and the second corresponding gear;
• b. the first, second, third, and fourth half-gears having a toothed section covering a portion of a circumference each;
• c. the first and second half-gears being configured to rotate synchronously and in alternately toothed engagement with the first shared gear rack so that only one of the first and second half-gears is engaged with the first shared gear rack at a time;
• d. the third and fourth half-gears being configured to rotate synchronously and in alternately toothed engagement with the second shared gear rack so that only one of the third and fourth half-gears is engaged with the first shared gear rack at a time;
• e. the first and second corresponding gears being configured to rotated synchronously with the shared gear wheel;
• and
• f. the first shared gear configured to produce reciprocating motion in response to the alternate engagement with the first and second half-gears, the second shared gear configured to producing reciprocating motion in response to the alternate engagement with the third and fourth half-gears.
