Device to transform rectilinear alternating motion into intermittent rotary motion

A device for transforming alternating rectilinear motion into intermittent rotary motion, comprising:

• at least one fixed base element with a face having a cam guide means;
• a moving slide element associated with said face of the fixed element, said moving slide element comprising a mechanical locator means following said cam guide means and susceptible to alternating movements on and with respect to said fixed base element;
• and
• an index plate rotatably associated with said fixed base element, interacting mechanically with the moving slide element and susceptible to angular rotation pitch in response to the alternating movements of said moving slide element, said index plate being connected to an indexed rotary table to be commanded, wherein the cam guide means of the fixed base element is in the shape of endless grooving, and the mechanical locator means of the moving slide element is compelled to follow said cam guide means, said mechanical locator means comprising pegs.
