The frame of this press is as F, into which two sectors are so arranged as as to have the great advantage of both the toggle-joint and the eccentric, separately and combined, as shown at D and E, by means of the lock at D, and also of pulling out the punch with, ease and certainty, by simple eccentric plates on the bottom part of the sector, as at A, which sector is hinged to the piston, and the eccentric plates, pressing on plugs or bearings, on the press frame, as at B, pull out the punch by the reverse motion of the lever. After thus drawing the punch, the whole works are most beautifully carried up to their places by mere slight rods, passing through the pillars of the press, with simple India-rubber balls on top, at C. Both sectors work on good tempered cast steel bolts, which are durable, and fully retain their centres. The press is simple, and will not get out of order; and so powerful, that an ordinary man can easily punch 11-16 hole, or more, through one-quarter inch iron with one finger only, by taking hold of the bare lever.
