WR. DAVID MEADE RANDOLPH's, (Got- 
- pen saquart,) for a@ Method of Manu- 
facturing all kinds of Boots, Shoes, §c. 
‘by means of a Substitute for Thread 
made of Hemp, Flax, or other Yarns. 
This substitute is applicable only to 
the soles and heels of boots and shoes, 
as all the other part of the work is per- 
formed in the usual way. The last used 
for this purpose is thus described: the 
common shaped wooden one, when ad- 
justed, is to be sheathed or covered at 
the lower part or bottom with a plate of 
iron, or other metal of about the thick- 
ness of a stout leathern sole: in this state 
it is secured and fastened. The sub- 
stitute here alluded to, is little nails, 
brads, sprigs, &c. formed or made of 
copper, iron, steel, or other proper me- 
tals, of such lengths as will allow them 
to reach and perforate the inner sole, 
with which the metal is in close cantact ; 
and when having been driven, they must, 
from the resistance, be clenched or ri- 
yetted through the leather, and serve in- 
stead of sewing, now in use, This in- 
vention in its application, is not confined 
to the edge or margin of the sole; but 
may be performed at any intermediate 
space where strength and durability are 
required, as appears from the nature of 
the /ast; the only difference of which 
from the common one, and the additi- 
nal sole described, being in form and 
shape precisely alike, is, that in this sole 
there are three round holes of nearly an 
inch in diameter, which perforate it, 
and are placed equidistant from one ano- 
ther, viz. in the centre of the last, one 
near the toe, another about half way be- 
tween the toe and the heel. These holes 
are to be filled up with wooden plugs, 
and are made for the purpose of fastening 
to them the shoe or boot, while making ; 
because, without this contrivance, it 
would be impossible to secure or nail 
the lJeather to the last, in order to make 
the boot or shoe; but when thus adjust- 
ed, there is no farther difficulty. Mr. 
Randolph applies, as a substitute for 
thread made of hemp, flax, dc. in the 
fabrication of traces, or other articles, 
to which the same may be usefully ap- 
plied; and in lieu of stitching or sewing, 
wires nade of iron, brass, or copper, or 
wires made of anv other fit metal. These 
wires he uses lengthways, by stretching 
them tlie whole length of the brace, &c.; 
aod they are fastened at each end round 
small wetal cyliuders, iuclosed between 
wi.’

MR. JOHN KENT’s, (SOUTHAMPTON,) for 
a new Method of Moving all Kinds of 
Goods, or Materials, to High Buildings, 
or from Deep Places. 
The invention described in the speci- 
fication now before us, is said to be an 
improvement on the principle of a lever, 
on a moving fulcrum, whereby power is 
gained without loss of time. The draw- 
ings attached to the specification shew 
its principle and mode of operation in 
the simple, and also in the compound 
state: the first two figures represent a 
weight to be raised, which is supposed 
to weigh four hundred weight; to be 
suspended by a rope, or chain, passing 
over a pulley, and fastened at one end 
to the weight, and at the other to the 
centre of the wheel, which wheel is sup. 
posed in itself, or by a weight attached, 
to be heavier than the weight to be 
raised. The patentee, we apprehend, 
supposes the diameter of the wheel to 
which the power is applied, to be twice 
the length of the axle round which the 
rope attached to the weight is to be 
coiled, though it is not well expressed ; 
and in that case, the ‘power of one-half 
the weight, or of 2cwt, will undoubtedly 
balance the weight of 4cwt.; but the 
wheel is also moved along an horizontal 
plane at the same time, so that the 
weight must be raised as much as the 
wheel moves on the surface of the ho- 
rizontal line, or plane, which supports it. 
We refer the reader to the specification 
itself for an illustration of the invention, 
as applied to the compound engine. ‘It 
may be used in direct rotative, pendu- 
lum, crank, or any other kind of mo- 
tions; and may be worked either by ani- 
mal strength, by water, by wind, by 
steam, or any other kind of agent that 
may be best adapted to the place or 
purpose required: it is also applicable 
to mills and pumps, to the moving care 
Tiages on iron-railways, and \to various 
other kinds of machinery.
