The great difficulty hitherto attendant on pressing goods in boxes, consists inthe parting of the sides and bottom of the box under tht pressure of the screw. To obviate this disadvantage, an improved method has been invented by J. E. Earle, Esq., of New York, who has taken measures to secure a patent. For this purpose two clamps are employed, which secure the bottom and likewise the sides of the box from the pressure of the screw-bed and follower. These latter are slotted, so that the clamps can pass through, and in like manner the clamps have apertures for fixing a couple of pins, against which the screw-bed bears when the screw is turned for forcing down the follower. .
