THE NEW PATENTS LATELY ENROLLED. 
ae 
MR. HUDDART, Of ISLINGTON, for IM- 
PROVEMENTS 772 the TARRING and MA- 
NUFACTURING of CORDAGE. 
HE object of the prefent improve- 
ment employed by the patentee is a 
better method than is ufually praétifed in 
applying tar to cordage, where this {ub- 
ffance is employed in order to give greater 
firength and durability by excluding the 
peinicious eficéts of confant wet upon the 
texture of the rope. The method of tar- 
ring here ufed is to arrange a number of 
reels or bobbins containing the white yarn 
by the fide of the tar kettle, to wind them 
off through holes, or over rollers or fepa- 
rating fticks, with a very equal and mode- 
rate tenfion, and in this ftate to pafs them 
through the tar. The threads are col- 
Jeéted on the other fide of the kettle by a 
regifier asthe patentee terms it, (which 
as the fubjeét of another {pecification o! 
tained laft year by the fame patentee) the 
ufe of which is to collect with a finoorh 
and even tenfion every thread of which 
the rope is compofed, and by paffing it 
throuch a tube to give ita precife degree 
of forfion or twifting, whereby the full 
Rirength of every thread of the rope is ex- 
erted at the fame time. This operation 
likewife {queezes the fuperfluous tar from 
the threads, which returns into the kettle, 
or may be further colleéted by another ¢lip 
or tube which icrapes’ the furface of the 
yope clean. It is thendried and hardened 
in the ufual manner. The great benefit 
of this procefs feems to be that of expo- 
fing every thread equally and feparately 
to the aélion of the fluid and heated tar, 
whereby it becomes thoroughly impreg- 
nated with this fubftance, and faturated 
with it, with lefs trouble and difficulty 
than by common methods. The tar. ket- 
tle fhould be fomewhat long, that the yarn 
may pafs through a fufficient bulk of this 
Jiquid while drawing through; and the 
temperature fhould he regulated by a 
thermometer, and kept as low as is con- 
fiftent with a requifite degree of fluidity, 
both becaufe, if very hot, the tex'ure of 
the thread is fomewhat im paired ; and be- 
caufe the tar fo foon parts with its vo- 
Jatie oil, and approaches to the ftate 
of pitch, and thereby becomes too te- 
macious and difficult to be kept proper 
for working. 
“MR. ISAAC HADLEY REDDELL, of BIR~ 
MINGHAM, for a NEWLY INVENTED 
METHOD of CONSTRUCTING TRA- 
VFLLING avd DRAUGHT CARRIAGES. 
Tue object of this invention is to con- 
firuct carriages which may travel either 
on land or in water, in order to facilitate 
inland navigation conveyance. The idea 
here put into practice is fimply that of 
making the body of the carriage in every 
refpect water-tight, like a boat, with as 
recefs (likewife water-tight) for the 
wheels ; and hence the unlading of goods, 
and fhifting them from a waggon to a 
barge may be faved. The patentee makes 
_ thefe wheeled boats of various burthen 
frcm two to twenty tons, and of various 
form ; fometimes a feries or fet of com- 
pariments, which when contiguous to each 
other in the water, may take up the room 
of a common barge (the headmot piece of 
a cut-water form) and be navigated inthe 
fame manner. 
Thefe boat-waggons obvioufly require 
an inclined plane and confiderable machi- 
nery to be paffed from land to water.

MR. REDDELL, for az IMPROVEMENT in 
the CONSTRUCTION of SADDLE-sTIR-_ 
RUPS. 
THE conftruction of thefe ftirrups is 
almoft exactly the fame as the whele- fhoe- 
ftirrups affixed to ladies’ fidie-faddles ; only 
wrought in metal, either folid, or in wire 
work, which ts capable of confiderable or- 
nament. The patentee likewife affixes 
fpurs to the heel of the ftirrups, which 
willtake on or off, or ftand cut, or turn. 
down, by means of {pring faftenings, and 
it is for this idea of adding the {pur to the 
ftirrup inftead of the boot, that he chiefly 
claims the patent.

0” G2 IMPROVED CONSTRUCTION. 
THe whole of this ingenious piece of 
mechaniim it is impofirble to defcribe 
without a reference to the plate. A con- 
fiderable difference exifts between this and, 
the ufual conitruGion, both in the form of 
the fails and the regulation of their power. 
The whole fail has the ufuai outline form, 
but,
