tending metal skeleton arranged near each end and con-
nected to the metal skeleton of the shell, and concrete
moulded around and between the adjacent inwardly extend-
ing metal skeletons of two consecutive shells, and also
moulded integrally with the concrete of the said two con-
secutive shells, whereby a common stiffening and connecting
diaphragm is formed at the joint of and integral with said
two consecutive shells, substantially as described. (20.) A
building block or structure comprising a relatively thin shell
composed of concrete moulded around a rigid strengthening
metal skeleton, and a diaphragm arranged intermediately and
composed of concrete moulded integrally with the concrete
of the shell, and with or without a rigid strengthening metal
skeleton, substantially as described. (21.) A building block
or structure comprising a number of relatively thin shells
arranged end to end, each shell consisting of concrete
moulded around a rigid strengthening metal skeleton, and
having a peripheral jointing edge at one end and a convex
peripheral jointing edge at the other end, and cavities at in-
tervals around each end, leaving the rigid skeleton bare at
such places, cement filling the joint between the peripheral
jointing edges of the adjacent ends, concrete filling up the
aforesaid cavities in the adjacent ends, a rigid metal skele-
ton connected to the metal skeleton of the adjacent shell,
concrete moulded around and between the said metal skele-
tons and integral with the cement in the joint and with the
concrete in the aforesaid cavities, whereby a connecting dia-
phragm is formed at the joint of two consecutive shells, sub-
stantially as described. (22.) Structures composed of con-
crete rammed or moulded around an internal strengthening
metal skeleton, substantially as described, and as shown in
Figs. 1 to 43 of the drawings.

Sheridan Avenue, Kearney, Essex County, New Jersey,
United States of America). Improvements in or relating to
dough-moulding machines.

Claims.—(1.) A dough-moulding machine comprising
rollers for forming a lump of dough into a sheet, a rotary
rolling-up device for rolling the sheet into spiral form, and a
pressing and rolling device for working and kneading the
spiral, and forming the same into shape for the baking-pan,
substantially as described. (2.) A dough-moulding machine
having spaced sets of revolvable rollers, of which one roller of
each set has annular flanges, the other roller of the set ex-
tending between said annular flanges to form a passage
between the rollers of a set, the passages for the sets of
rollers being of different widths, substantially as described.
