Abstract
Abstract A mechanism for controlling the velocity of a tool platform in a manner causing the platform to follow a moving product at product speed while machine operations are performed on the product. The mechanism comprises a platform reciprocally driven by a roller chain coupled to a slot in the platform, the orientation of the roller chain being altered to control the velocity and distance of travel of the platform.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
187 words
A transmission employing a velocity control device comprising: a support, a slotted tool actuating platform mounted for reciprocal movement on said support, drive means mounted adjacent said platform and connected thereto for causing reciprocal movement of said platform, said drive means comprises a pair of sprocket means each having an endless means mounted thereon for movement thereby upon rotation of the associated sprocket means, a pair of following means one mounted on each of said endless means for movement therewith, a support rod, a slide bracket laterally positioned across said rod for slidable movement along said rod, a pair of spacedly positioned axially aligned slots formed in said bracket to extend longitudinally thereof, each of said slots loosely engaging a different one of said following means for causing said bracket to be reciprocally moved along said support rod over a portion of the travel of said endless means and to be relatively stationary during a second portion of the travel of said endless means when said following means moves along said slots, and a roller mounted on said bracket for riding in the slot of said platform
