A MODIFIED CAPSTAN FORCE AMPLIFIER

Abstract

The best-known force amplifier is the common capstan drive. The principal disadvantage of this device is the crawling of the line parallel to the driving drum. The sliding of the line back toward the center of the concave driving drum produces intermittent jerking of the takeup line. A modified capstan drive which eliminates this undesirable crawling and consequent jerking has been designed and built. Basically, the function of this device is to reel in under load and store under reduced tension many layers of line. The device is a low-speed, lightlyloaded unit. However, there appears to be no reason why the drive could not be scaled either up or down in size or speed. (Author)
