Abstract: An article slotting apparatus that includes a base member and a vertical support member, with a fixed platen connected at its rear edge area to the support member. Movable posts pass slidably through bores in the fixed platen and are connected at first ends to a lower platen and at their second, upper ends to a head platen. The posts, lower platen, and head platen can move in unision and are driven by a threaded shaft that is movable with respect to the support member. A slotting tool extends down from the lower platen and the space between the tool and the base member is relatively free of obstructions.
