A rotary moulding-machine for shaping metal sheets.

Claims.—(1.) In rotary moulding-machines for shaping
metal sheets, the lower and upper rotary dies provided with
convoluted surfaces, and having a slit or recess or several of
such, to receive and retain the metal sheets preparatory to
bringing the convoluted surface of one die into contact with
the convoluted surface of the other die, as described and
shown. (2.) In rotary machines of the class set forth, the
combination upon a lower and upper rotary die of two or
more moulding-devices, either the same or of varying dimen-
sions, adapted to produce ogee guttering, mouldings, and
suchlike, as described and illustrated, and for the purposes
set forth. (3.) In rotary machines of the class set forth, the
combination with a lower rotary die of a detachable strip
alike adaptable to ogee gutters of varying sizes adapted to
produce a slit or recess and the rounded bead, as described
and shown and for the purposes set forth. (4.) In rotary
machines of the class set forth, the combination with the
upper and lower rotary dies of a detachable strip alike
usable with the horn of the upper die and a portion of the
convoluted surface of the lower die, to either enlarge or
reduce the dimensions of the articles to be moulded, as
described and shown. (5.) In rotary machines of the class
set forth, the combination of two rotary dies, one of which
is provided with horns to limit the range of movement and to
necessitate a reverse movement in the machine to produce
more than one moulding operation, as described and shown.
(6.) In rotary machines, the combination of the upper and
lower rotary dies with the beading devices such as are
described, and for the purposes set forth. (7.) In rotary
machines of the class set forth, the combination with con-
voluted surfaces adapted to produce ogee guttering of de-
tachable dies to produce mouldings other than ogee guttering,
as described and shown. (8.) In rotary machines of the
class set forth, the combination of the lower and upper
rotary dies provided with surfaces for attaching a variety of
dies with convoluted surfaces, the whole being arranged for
continuous rotary movement, as described and shown.
(9.) A rotary moulding-machine for shaping metal sheets,
having a lower rotary die in a fixed bearing and an upper ro-
tary die in an adjustable bearing, combined with a cushioning
spring, an adjustable cap, and a gapped standard for the said
movable bearings, as described and shown. (10.) In rotary
machines of the class set forth, the combination with the
