No. 14991.-12th June, 1902.-THE VICTORIAN FORAGEPRESSING COMPANY PROPRIETARY, LIMITED, whose registered office is at 112, Ryrie Street, Geelong, Victoria (assignees of James Ferrier, of Eastern Beach, Geelong aforesaid,
Farmer). An improved forage press.

Claims.-(1.) An improved forage press consisting essentially of a top and bottom box constructed as specified, a
movable ram to carry said boxes and compress the forage
against the stationary ram into the bottom box, and a collapsible feed-chute connected to the enlarged end of the top
box, substantially as described and illustrated. (2.) In a
forage press, a bottom box consisting of four metal plates
carried by transverse angle-irons, those on the two sides
being set apart and those on the front and back being
riveted together, and all pivotally mounted on diagonally
opposite rigid standards, substantially as described and illustrated. (3.) In a forage press, mechanism for opening the
doors of the bottom box without violence when the forage is
compressed, consisting of two sets of locking levers and
rollers mounted on vertical rods on the outer or free ends of
the side doors, said levers having lateral projections to engage fixed rollers on the angle irons of the front and rear
doors, the ends of which are curved so that the rollers on the
side doors will act gradually in either opening or closing, and
a yoke for retaining the levers, substantially as described and
illustrated. (4.) In a forage press, a collapsible feed chute

solenoid energised by the current of a dynamo driven by
the electro magnetic coupling, substantially as described.
