Volume control mechanism for a bell assembly

A volume control mechanism for a bell assembly having at least one bell dome and a bell ringer hammer supported on the end of a pivoted stem, comprising a resilient member, said resilient member being movable into contact with said stem to apply different predetermined forces to said stem so as to vary the amplitude of movement of said stem and said ringer hammer when in operation, a lever, said lever being pivoted adjacent to said stem pivot in the same plane as said stem and supporting said resilient member, a resilient rod and a rigid rod, said resilient rod and said rigid rod being secured to said lever with their axes perpendicular to the plane of movement of said lever, a block, said block being fixed relative to the at least one bell dome and having guide means for guiding said rigid rod and a plurality of grooves formed thereon, the axes of said grooves being perpendicular to the plane of movement of said lever, said resilient rod engaging said grooves being perpendicular to the plane of movement of said lever, said resilient rod engaging said grooves formed in said block and said rigid rod engaging said guide means formed in said block, whereby said rigid rod in said guide means maintains said resilient rod in contact with said grooves at all times.
