RECENT IMPROVEMENT IN THE USE
Full ARTS, PATENTED IN THE UNI
TED STATES.
From the ssrepor Of the Commissioner Patents, we
proceed to lay before our readers an abstract OF
some of the most important and interesting inn
provements in the useful arts, made during the past
year. as WIS find them brought together in the APP
pended reports OF Messrs. G.. M. Keller and q. G.
Page, aExaminer in the Arts" We proposc on a
future occasion to c0ndense the valuable agricultural
information contained in the main body of the re-
port.
In MErALLURGY, new apparatus for washing
gold from its impurities has been introduced, sub
iectng it to both horizontal and vertical current
of water, by means of series of selves in a
water.tank The much more important metal OF
iron has had its smelling facilitated by using its
escaping gases, mixed with air, fuel. In this
way all the gases instead of escaping heretofore,
are consumed in the immediate neighborhood of the
iron where the heat is required and the oxygen of
the atmospheric air is not permitted to act injurious
w upon the iron whilst heating it. A patent has
also been granted for the manufacture of maeabe
iron directly from the ore.
"a variety Of simple and compound substances have
heretofore been mixed with iron In the melted state with
producing highly refined metal; and modifca.
on OF these processes another patent has lately been
pudding compound OF sulphur nitrate with borax,
soda potash and alum broken in small Jumps, and in
troduced below the surface OF the melted from the proper
tons to varied the iron is intended for the
ire of steel"
A new application of electricity, an element with
which we are so rapidly becoming 80 familiar, has
been made TO the manufacture of iron The in
ycntion consists in subecting the iron, whilst in
fluid state and also whilst in the act of congeang
or solidifying which is caused to traverse COM
pletely as possible throughout the entire metallic
mass. The full specification is given in the report.
On steel, Mr.. Keller makes suggestions worthy Of
attention He says:
an the manufacture steel which has thus far made
very little progress this side the Atlantic bpt little has
done by counymen and fear that the prevalent
best qualities Of steel can only made from Swedish iron
tends in great to etard enterprise and
prshend why notion BY sound reason
have attained much prevalence this Science clearly
iron in M purest state; and to obtain this latter requires
skill and experiencehese being the only impedimens to
nearly every variety iron good be assign
dicens
In the working Of biaeksmias' FORCES, the accumu-
lation Of cinder is a matter of much Inconvenience,
particularly where large masses of iron are worked.
The accumulation of cinder has frequently to be re-
moved, which not only consumes much time, but
disturbs the fire.
ITO avoid this Inconvenience an Improvement been
forge to slide up down in sink WE'LL that
~ fresh charge the hearth descends
the cindey IT. and when the hearth reaches the bot
tom Of the sink or well the whole Of the cinder removed
through hole in the bottom and the hearth is forced up
to the top TO recommence"
The forging of blacksniihs' anpiIs the rveting Of
boiierpiates, the making Of buti-hngss of cast or
wrought iron, nail machines, &c., have also been
subjects of patented improvements
In the department of FERROUS AND TEXTILE SUR
STANCES, Improvements have been made in cotton.
gins, in ,cooLcombing, and in cleaning the cards.
The important work Of preparing the fbres Of
hemp, particularly in the West seems to labor un-
der ahy disadvantages in the ignorance Of the in
ventors, who rcdiscover old processes Mr.. Keller
suggests the diffusion among them Of scientific in
formation from the Patent Office.
In England, processes have been patented for rem
dering cotton fabrics repellant to water; and for
coating cloths, leather, &C., with metal, by gal
vanic means. The specifications are given in the
report.
"A machine lately patented for making Tuscan
braid, for ingenuity and beauty OF mechanical ar
rangement is worthy of the highest commentator
After the pieces of straw have been deposited in
box, the whole operation Of taking each separate
piece introducing, bending it over, trimming of the
surplus, and transferring and reransferrng the pin
GERS or nippers by which the pieces are held, and
the completed braid delivered is carried on with the
most beautiful regularity, without the hand of ar
attendant.
