Abstract
A press is described having an upper platen. The press includes one piece base for support an upper rotatable support arm and a lower cantilever support arm. The upper support arm is adapted to selectively move the upper platen between an open position, a partially open position and a closed position with respect to a lower platen. A lower cantilever support arm configured to provide an open working surface around a lower platen. A sliding mechanism disposed on the base to selectively move the lower platen to an open, partially open or closed position.
Claims19
A press comprising:
- an upper platen;
- an upper support arm adapted to selectively rotate and move said upper platen between an open position, a partially open position and a closed position;
- a locking mechanism supporting said upper platen from said support arm, said locking mechanism configured to align said upper platen substantially parallel with a lower platen of the press, wherein pressure exerted by said upper platen upon the lower platen is substantially equalized across the face of said upper platen;
- a cantilever lower support arm adapted to support the lower platen;
- a base assembly adapted to support the cantilever lower support arm and the upper support arm, wherein the base assembly houses a sliding mechanism for selectively moving the lower platen translationally;
- and
- a lower support arm locking mechanism configured to selectively secure the lower platen to the base.
