This invention relates to improvements in me
chanically-actuated presses for trim tile.
One of the objects of this invention is to pro
duce a mechanically-actuated press which will
be capable of mechanically producing trim tile,
such as heretofore hasbeen made only in handoperated friction-drivenpresses. Trim tile so
made on our mechanically-actuated press will
when?nished be‘ as ?rm, strong and uniform
in structure .as theltrim tile made on friction
driven presses and. will be useful'as edging tile,
such as cap tile or base tile in tile panels.
Another object of our invention is to provide
in a press of the character speci?ed,v special co
operating heads on the upper and lowerplungers

of movements synchronized at an intermediate
position in such cycle of movements with’ the
. movement of .the ribbed plungers hereinabove
speci?ed, whereby an initial quick forward move
ment thereof will push and move a previously
pressed tile over a part of the floor portion of
the lower plunger away from the die cavity and‘

a transfer mechanism having a reciprocating
movement from a position adjacent to the die
cavity to a position adjacent-to an off-bearing
belt and return, and means; preferably compris
ing a combined ejecting and charging device,
for actuating said transfer mechanism to have
a tile-transferring movement from said position
adjacent to the die cavity to an off-bearing belt,
and a resetting movement from the off-bearing
belt to a position adjacent to the die cavity.
Anotherzobject of this invention is, in ame 6.0

an ejector and charging mechanism for releas

ing position and for delivering the tile to an offbearing belt.
Still another object of our invention is to utilize _
an ejector and charging device having a pusher
portion adapted in its forward movement to ex

of the lower die in the beginning of the ejecting
movement.

mittent movement or a plurality of separate
movements during a forward movement thereof,
and these forward movements will be loo-related
and synchronized with the movements of the
plungers to enable initial and quick pushing of
a trim tile from the die cavity onto a carrier
grill while the plunger rib is in raised position;
then to provide a dwell to enable a lowering of
the lower plunger and thereafter to provide a
subsequent rapid movement for actuation of a 10
