NEW PATENTS LATELY ENROLLED. 
BR. THOMAS 'DOBBS’s (KING’s NOR- 
TON), for the Maxufafure of a new 
WMetal, which be denominates Albioz 
Metal. Pe i 
HIS metal is intended by the-paten- 
tee to fuperfeie the ufe of lead m 
cifterns, cider-wats, and all other veffeis 
where it is fuppoled to be detrimental to 
the health. 
tin; that is fo fay, it is lead lined with 
tin,, fo that the tin may be always on that 
fide which ts expofed to the attion of the 
fluids. Fhe Albion metalis thus made: 
a'bar of lead, or any of its alloys, is to 
be placed againft a bar of tin, of equal or 
unequal thi icknefs, and the two metals 
thus fituated are to be pailed through tre 
rollers of a relling roachine, by the: aétion 
ef which they will fo uniie and cohere, as 
to be capable of being manu‘aciured into 
any forms. Jf it be neceflary to line the 
lead on both fides, thea tne plate or bar 
of lead is to be placed between two plates 
er bars of tin, and then pafled through ‘he 
rolling preis. Mr. Dobos recommends as 
wleful, if not neceflary, that both the lead 
and the.iron rollers fhould be made pretty 
hot before the operation is performed.

MR. ROBERT RAENES’s (HULL), for a 
feet of coz verting the Fins, ral, 
Sec. of the Whale Fifh into Glue. 
Phe fird part of this. operation confitts 
in cutting the parts!o be mede ufe of into 
pieces of about fourteen pounds en eae : 
thefe are to be put into boiling water, a: 
kept hot for twelve hours, to extra‘ % the 
greafe, and other matter which weuid 
hinder the converficn of the fubftance in- 
to glue. They are then to. be kept in 
cold water a confiderable time, taking care 
that the water is changed four times; af- 
ter which, to aton of fifhy fubfiaace, in 
a fort of bag, add 120 gallons of water, 
and boil them together twelve hours, when 
the bag is to be taken puts and with the 
remainder twenty pounds of alum aré to. 
be mixed, while it 1s fill in the copper. 
Having now food twelve hours, it is to 
be drawn off into coolers, and laid out on 
neisto dry, after the manner of common 
glue. 
MR.THOMAS ey 
for a Machine for hackling Flax and Hemp, 
and at the fame Time carding Tow. 
“This machine coniifts, firitt, of a part 
which Mr, Perthoufe calls jaws, for fixing 
(250°) 
Li is compounded of Jead and © 
amd ready for receiving the

ce] of the flax or hemp in a firm manner, 
whi the oppofite end of the flax, &e, 
undergoes the fublequent operation of 
hackling. The fecond part is called a 
turntable, om the edge of which the jaws. 
are fixed, for introdacing into the ma- 
chine tne handfuls of hemp or flax in wi 
aw flate, al(o for changi*g the fide of th 
flix during the operation ; and when He 
par :cels of fax become (uffiviently dreffed 
for turning them out of, of from, the aét- 
ing part of the ma achine, for the purpofe 
of allowing the handfuls already creffed 
at one end tobe taken out of the jaws, 
and changed and turned to the contrary 
end, or replacing them by wndrefied hand- 
fuls, as the cale fhall-require. ‘Fhe next 
part of. the inftrument is called the por- 
cupine, for drefiing or fplitting the fibres 
of. the flax or hemp, and delivering | it up- 
on {mall conical cards, for the purpofe of 
carding the fame; in a manner wiieiel is 
afterwards defcribed. The fourth confiftts 
of conical or bevel-faced cards for receiv- 
ing the tow frum the porcupine, and card- 
ing the flame, which is afterwards colleét- 
ed by rollers, nearly in the fame manner 
as from the commen carding engine. The 
\ 
latt part is machincry for. giving the re- 
quifite velocity to each of the other parts 
cf the machine. 
The drawings attached to this fpecifi- 
cation ex ibit Hie jaws, which are to be 
made of caft iron or other metal, open 
handful 
of flax or hemp: they alfe thew how 
the flax is fixed into the jaws, ready for 
the ful fequent cperation of hackling or 
drefing, and new three of thefe jaws are 
fixed upon, the edge or outer rim of the 
turn-table, at equal diftances from each. 
other. There are other drawings which, 
with the aid of what is written, defcribe 
tre whole operation. Several of the turn- 
tables a:e placed at convenient diflances, 
and ranged in a-circular dir ¢tion round 
one common center, for the purpole of 
being a&ted upon by the po: cupines. 
The body or barrel of the porcupine is 
made, of wood. and is about nine inches 
long, and fix inches diameter, ftuck or 
filed with fteel pins, fimilar to thefe ufed 
in the common hand-hackle, and project- 
ing in radii from the body or barrel of the 
porcupine, of different lengths and fines

fing advances in finenefs during the ope-
