Abstract
A sheet paper feed apparatus for a typewriter having a frame supporting a platen for holding and providing at least longitudinal motion to a sheet of paper. A rectangular tray includes forward and rear paper supports for supporting a stack of paper thereon. Therebetween is a shinglar roll or wheel which supports the central portion of the paper stack is a slightly bowed configuration. The shinglar wheel is first driven in a rearward fashion to effect removal of the forward or leading edge of the bottom most sheet from the stack away from the forward support, and then the shinglar wheel rotation is reversed effecting feeding of the sheet of paper away from the bottom of the stack and below the forward paper support into paper feed rolls and ultimately onto the platen.
