.~ With means varying the material speed during movement
DEFINITION
Classification: 226/122
(under subclass 120) Device including means for changing the rate of travel of material during an increment of movement.
(1) Note. This subclass includes only those patents in which the claims specifically set forth the change of rate of travel during each step. It is obvious that in any intermittent feeder the material must accelerate from zero and decelerate to a halt, thus patents have not been placed in this subclass on that basis. The patents herein disclose devices which provide specific means which may, for instance, provide a slow acceleration to start the material, than a faster acceleration for some duration of time and then a deceleration to bring the material to a halt.
(2) Note. Exemplary of the patents herein is a device disclosing planet and sun gear train in which the planet gear is described as having hypotrochoidal motion.
