the spring biased separator wheel assembly 16 follows the profile of cam 61 as nipple 58 is urged against cam 61 this causes the separator wheel assembly to rise from its bite adjustment position the jam can now be cleared without damage to the jammed sheet reversing the levers 65 returns the cam 61 is its normal or high side eccentric position as shown in fig1 and 2 thereby returning the separator wheel assembly to its bite adjusted position for separating and feeding individual sheets it has been found that the preferred embodiment of the present invention provides an additional capability to the feeder which previously was unavailable due to the nature of the interference type separator when the separator wheel assembly is in the raised position multiple or single sheets can be manually fed as desired through the feeder 10 for further processing such as folding and insertion into an envelope downstream of the feeder 10 this procedure is referred to as a 34 daily mail 34 feature which allows an operator to process manually multiple sheets and individual sheets as needed without affecting the bite adjustment of the separator wheel assembly 16 for feeding sheets stacked on the feed deck 14 when the cam 61 is returned to its normal position it has been found that when multiple or single sheets are manually fed with the separator wheel assembly 16 in the raised position the motor 24 can be energized to drive separator wheels 20 and prefeed wheels 30 to assist.
