With every complete revolution of the counter balanced drive wheel thefeed pawl engages precisely on to the gear which moves towards and advances theobject holder thought a cone, inclined plane mechanism in such a preciseincrements that tissues can be sectioned even in one micron thickness. When thelimit of the feed is reached at the end, a safety device automaticallydisengages the feed mechanism to prevent jamming and damage to the feed screws.The feed indicator is located in the front and feed setting is controlled by aknurled knob at the back of the microtome, to adjust section thickness from1-50 microns in steps of one microns each.
