JoRDAN’s SUSPENDED BRIDGES. 
_ The year 1794 having proved very de- 
ftruétive to bridges, many ingenious men 
have fince brought forward plans, with a 
view to prevent the effects of fevere 
frofts, fucceeded by rapid thaws. Letters 
patent have been granted to Mr. JAmes 
Jorpbawn, of Oakhill, near Shepton Mal- 
let, for his invention of a mode of con- 
ftruéting bridves, which unites fimplicity, 
cheapnefs, durability, and an eafy mode 
of erection, in fituations where, to build 
other bridges might be found difficult, if 
hot impraéticable. 
The great caufe of damage having hi- 
therto arifen from piers which are contihu- 
ally weakened and impaired by the aétion 
of the water, and of fheets of ice, floods, 
&c. the prefent patentee, to avoid thefe, 
in fome cafes entirely, and in others par- 
tially, propofes to derive his fupport from 
above, and not from delow as in the ufual 
way. His plan is, to place ‘wo parallel 
elliptic curves acrofs the intended fite, 
formed of caft or wrought iron, or wood, 
and fpringing from fufficient abutments. 
He then propofes to attach the bridge to 
thefe curves, by*means of wrought iron 
fufpending bars; at any height frow the 
water that may be required. © 
The patentee conceives, that many 
rivers may befpanned at once. In cafes, 
however, wherein, from the great breadth 
of the river, one fpan would be hazard- 
ous, he propofes, that a continuity of 
curves, or arches, may be erected upon 
intermediate piers. On navigable -ri- 
vers, a draw-bridge may be made in the 
centre of the fufpended one. 
The bridge of one fpan, and that of 
feveral fpans, have, in the drawing, an 
appearance beautifully picturefque. The 
road over them, as fufpended by the caft 
tron curves, forms a fort of chord to the 
curve line, and they poffefs this very 
peculiar utility, that they are perfely 
ftraight and flat, and have ho rife or 
crown, as in bridges cf the prefent con- 
ftruction. 
Cooper’s MasuinGc MACHINE. 
On the 9th of September, letters pa- 
tent were obtained by Mr. THomas 
Cooper, Engineer, Old-ftreet, London, 
New Patents, éc.—Original Anecd.tess 
for his invention of a machine for mafh_ 
ing or mixing of malt, &c. by means of 
horfes, wind, fteam, or water, inftead of 
manual labour. 
The machine is put in motion, in the 
mafh tun, by an horizontal fhaft, which 
communicates with the horfe wheel, or 
other power. 
_ At confifts, 4, of az upright fhaft fixed 
in the centre of the mafh tun, which js 
turned on its axis by cogs that work in the 
horizontal fhaft above-mentioned. 
2, Of two “horizontal fhafis within 
the tun, which extend from the central 
or upright fhaft towards the periphery 
of the tun. One of thefe fhafts is fituat- 
ed near to the bottom of the tun, and 
the other is fituated level with the top of 
the tun. Thefe two horizontal fhafts are 
turued on their axes by cog wheels, which 
are affixed on the central upright fhaft, 
and on that extremity of them which 
adjoins the central fhaft. 
3; Over the two horizontal fhafts 
work endlefs ropes or chains in any requir- 
ed numbers, which are regulated in their 
moticn by arms. or crofés aitixed to the 
ihattss 7 ; 
4, ‘To the endlefs ropes or chains” 
are affixed, horizontally, any number of 
Yakes, oF combs, made of iron or wood ; 
which rakes neceffarily afcend or defcend 
by the working of the chains over the 
thafts. 
{cent of thefe rakes or combs, the intef- 
tine operation or mixture is performed. 
5, Yo give to the whole the cir- 
cuitous motion round the math tun 
which is neceffary, there is affixed to 
the extremity of the upper fhaft, a cog 
wheel, which works within a frame, that 
moves and is fupported on the edge of 
the mafh tun. 
6, In this frame is alfo affixed a 
fmall upright foaft. On the upper end 
of this fhaft is a contrate wheel of various 
fized cogs, which is turned by the cog 
wheel (art. 5.) On its lower end is a 
cog wheel, which works in cogs that ex- 
tend entirely round the edge of the mafk 
tun. This laft motion effects the revo-~ 
lution of the whole machine through al 
the parts of the malt and liquor. ,
