No. 16349.—14th May, 1903.—CYRIL FREDERICK DUNN,
of 18, Gordon Avenue, Kew, Victoria, Accountant (assignee
of Joseph Bartlett Davies, of “Elouera,” Wheatland Road,
Malvern, Victoria, Accountant). Improvements in and re-
lating to soft-metal-headed wire nails.

Claims.—(L) In iron or steel wire nails having a soft-metal
head-enlargement, the direct union of the soft-metal head-
enlargement with the wire-nail head by the “se of a suitable

other appropriate material or materials may be used, sub-
stantially as described. (2.) In iron or steel wire nails
having a soft-metal head-enlargement, treating the wire-nail
head with a suitable flux or fluxes, and the” casting the soft-
metal head thereon within dies, to which the molten metal
is forced under pressure, substantially as described. (3.) I”

scribed. (4.) I” iron or steel wire nails having a soft-metal
head-enlargement, heating the wire-nail head to about the
temperature of the molten metal which is to form the head-

die or pair of dies of the requisite form, and passing the
molts” metal thereinto under pressure, substantially as de-
scribed. (12.) A soft. metal head -enlargement formed
on an iron or steel wire nail which has bee” previously
galvanised, coppered, or tinned, or made from galvanised,
coppered, or tinned wire, substantially as described. (13.) A
soft-metal head-enlargement formed on an iron or steel
wire nail which has bee” previously galvanised, coppered,
or tinned, or made from galvanised, coppered, or tinned wire,
by forcing the molten metal under pressure to dies in which
the wire-nail head is arranged, substantially as described.
(14.) In the manufacture of iron or steel wire nails having a
soft-metal head-enlargement, treating the head of wire nails
previously galvanised, coppered, or tinned, or made from wire
previously galvanised, coppered, or tinned, with a suitable flux
or fluxes prior to casting the soft-metal enlargement about the
wire“sil head, substantially as described. (15.) A soft-metal
head-enlargement formed on an iron or steel wire nail which
has bee” previously galvanised, coppered, or tinned, or made
from galvanised, coppered, or tinned wire, by treating the
wire-nail head with a suitable flux or fluxes and then casting
the soft-metal head thereon within dies to which the molten
metal is forced under pressure, substantially as described. (16.) A soft-metsl head-enlargement formed on a” iron or
steel wire nail having a shank twisted or jagged or partly
twisted or jagged, and which nail has bee” previously gal-
vanised, coppered, or tinned, or made from galvanised,
coppered, or tinned wire, substantially as described (17.) A
soft-metal head-enlargement formed on an iron or steel
wire nail which has bee” previously galvanised, coppered,
or tinned, or made from galvanised, coppered, or tinned
wire, treating the iron head thereof with a suitable flux
or fluxes, the” casting the soft-metal head-enlargement
thereon, substantially as described. (18.) I” iron or steel
wire “ails having a soft-metal head-enlargement, treating the
wire-nail head with a suitable flux or fluxes, the” casting the
soft-metal head-enlargement thereon within suitable dies, and,
after the soft-metal head is solidified, again further shaping
and compressing the soft-metal head-enlargement, substan-
tially as described. (19.) I” iron or steel wire-nails having a
soft-metsl head-enlargement, treating the wire-nail head with
&suitable flux or fluxes, the” further heating the prepared
nail-head by passing it through a molten-metal bath, or in
other ways, and the” casting the soft-metal head-enlarge-
ment on it in suitable dies, and, after the soft-metal head-
enlargement is solidified, again further compressing and
shaping the soft-mete, head-enlargement. substantially as
described.
