Abstract
The rocking lever for a cam mechanism presents a hollow box-type structure and consists of a modular base piece provided with the trunnions and with the cam follower rollers adapted to cooperate with the cams. The modular base piece presents two connection surfaces, arranged at 90.degree. with respect to each other, and adapted for the fastening of modular appendix pieces. The said modular appendix pieces can be secured in a removable and changeable manner to the modular base piece.
Claims2
A modular rocking lever comprising in combination:
- a modular base piece haing a hollow box-type structure and being provided with trunnions forming a pivot axis for said lever, and with two connecting surfaces which are perpendicular to one another and which each have at least an elongated portion which forms an edge of said base piece and whose longitudinal axis is perpendicular to said pivot axis;
- the edge of said base piece opposite one of said portions of said connecting surfaces is open;
- first and second modular appendix pieces with said appendix piece being of a desired length and having a hollow box-type structure;
- means for fastening said first appendix piece to one of said connecting surfaces in a removable and changeable manner to form a first arm of said lever;
- means for fastening said second appendix piece to the other of said connecting surfaces to form a further arm of said lever;
- and at least one cam follower roller rotatably mounted within said base piece adjacent said open edge.
