Low Capacity Envelope Hopper

Illustrated is an envelope feed mechanism which is designed to assure proper picking and feeding of a stack of envelopes.

As shown, there is a frame 1 which includes a throat 10 into which a stack of envelopes 8 is inserted. Upon insertion of the stack of envelopes 8 the spring loaded bed upon which they rest is depressed by the operator, thus compressing the spring 9 such that the envelopes can be placed into the picking area.

Upon release of the pressure on the envelopes, they and the spring expand and cause the lower extension of stop 3 and the feed roller 4 to be contacted by the envelopes. The feed roller mount 6 to which stop 3 is attached by a screw then rotates about a pivot point on the axis of roll 5, thus moving the lower extension of the stop 3 out of the envelope throat 10.

As shown in the figure, the envelopes 8 are depressed and in the usual situation a full stack of envelopes would be inserted by the operator. The lower portion of the stop 3 would prevent insertion of an excessive number of envelopes, such that choking of envelopes at the picker separator area upon release of operator pressure is prevented.

Upward motion of stop 3 is limited by the up stop 2 while lower motion of stop 3 is limited by the low stop 2a. Thus envelopes 8 can be fed through the picker separator rollers 5 and 7 in a reliable manner.
