THE NEW PATENTS LATELY ENROLLED. 
ee 
MR. EGGS, for @ METHOD of BENDING 
STEEL. 
NSTEAD of employing heat, as is 
ufually done, the Patentee proceeds 
in the following manner:—Having fhaped 
the blade, fpring, or whatever elfe is 
wanted, he ftretches it over an iron (tech- 
nically called a flat) which is convex at 
the part over which the fteel is paffed. 
He then ftrikes the bent fteel for a great 
number of times with an iron of a chiffel 
form, which -cuts into the fteel, and the 
bending is compleated. ‘This he thinks 
will fave much trouble and labour, and 
will anfwer for feveral kinds of {fprings, 
furgical inflruments; and particularly for 
the bent {pring of rupture truffles. _

them for the fame time into a bath com- 
pofed of a pound and a half of white vitriol, 
a pound of cream of tartar, and an ounte 
of fal ammoniac, diffolved in twenty gal-. 
lons of water. Next add to the liquor ten 
pounds of vitriolic acid, one pound of 
nitric acid, and one pint of foirit of falt, 
which makes an acid bath, in which the 
fkins are to be flteeped for a fhort time. 
This will get off the lime that had been 
before employed for the parchment. The 
fkins are then to be wathed to rinfe out all 
the acid, and the water wrung out ag 
completely as poflible, without tearing the 
fkin. It is then-to be immerfed and well 
foaked in a tanning liquor, compoted of
