Abstract
A multiple-step cyclical ram advancing apparatus. In a three step configuration linear motion is imparted to a moving axis as revolution therearound translates said axis to provide a first linear push to a slide ram to abut articles, then a partial retraction of the slide ram during a period of dwell, followed by a second linear push to discharge the assembled articles. In other configurations, the ram is alternately advanced and retracted a varying number of times depending on the integer ratio of the number of revolutions of the pinion gear in half revolutions to the number of revolutions of the flywheel.
Claims8
Apparatus for cyclically advancing and retracting a ram in multiple steps, said apparatus comprises:
- a flywheel rotatably mounted on its central axis;
- a first connecting rod having one end rotatably connected to said flywheel a selected distance, D, from the central axis of said flywheel;
- a toothed rack mounted in a fixed position;
- a pinion gear having teeth therearound mating with the teeth of said toothed rack, a second end of said first connecting rod rotatably connected to the central axis of the pinion gear for imparting reciprocating motion to the pinion gear along the toothed rack as said flywheel is rotated, the pinion gear having a pitch circumference, C, equal to (2D)/N wherein N is the ratio of revolutions of said pinion gear in half revolution steps to the revolutions of said flywheel with N having an integer value of at least 2;
- an arm having one end affixed to the central axis of said pinion gear;
- a second connecting rod having one end rotatably connected to a second end of said arm with a second end of the second connecting rod extending away from said flywheel;
- and
- a ram slidably mounted on a fixed surface with the second end of said second connecting rod rotatably connected to the ram.
