is forced back upon the slide by the re- 
coil, it ig raised upon four wheels, by 
means of an iron spindle, with pinions 
upon it, and tour iron jevers or cranks, 
with cogs of teeth atthe end, which w ork 
in the pinigns on the spindle, and the 
wheels running upon plates of iron iet 
into the slide, will enable the gun to 
be got forw ard again, without tackle, 
and in considerably less time than the 
common Carriage. 
The carriage is made of two wood 
sides, or brackets, a bed or bottom, and a 
transtm, or cross-piece, framed together. 
The tron spindle is fixed about the mid- 
dle of the carriage, a little above the bed: 
it is made t “ound, aud passes through the 
brackets, at the inside of which are two 
, pinions uf six teeth, and a half pinion’ of 
three teeth on the middle. The ends on 
the outside are made square, to fix on 
handles, for the purpose of turning the 
spindle. The four iron cranks are fixed 
to the bed of the carriage, on the inside 
of the brackets. The two at the fore- 
part are made with a hole at one end, 
through which, and along a grove in the 
bed, an iron axle-tree passes, on the 
ends of which, at the outside of the cranks, 
are two iron wheels. At the circumfe- 
rence of the wheels is another hole, 
through which, and through the sides, aid 
bed, a bolt passes and serves as a pivot 
for fife cranks to act upon, and also to 
hold the carriage together. The other 
end is made with three or any other 
number of teeth, which work in the pi- 
Rions on the spindie. The two cranks 
at the hind part of the carriage are si- 
milar to the two at the fore part, only re- 
versed, so that by turning the spindle one 
way, the carriage will be raised upon its 
four wheels at once. This carriage, we 
are told, will not be so liable to decay as 
the common carronade-carriage ; because 
when the gun is housed, it may be raised 
upon its wheels, by which the air will 
be adnutted freely, and the wood pre- 
served, 
The patentee is able to apply the 
cranks and spindle to rope-maker’s 
sledges, or to any thing heavy, thatis re- 
quired to lie on a flat ‘surface and to. be 
occasionally moved, observing that they 
must be proportioned according to the 
weight that is to be lifted, and the hei ght 
to which it is to be raised. 
The principal recommendations of this 
Carriage are, that it can be worked with 
few hands, and with great expedition ; 
it occup‘es but little room, and may with 
agun of thirty hupdred w eiabt be pushed 
forward, after firing, by two men in less

time than the common carriage, and with- 
out the use of tackle or handspikes, it 
will be found very useful in case. the gun 
should not, with the recoil, come sutici- 
ently in port or inside the battery, as It 
may, by raising it upon its wheels, be 
broug ht in to reload with as little trouble 
ag it is pushed out, so that the men will 
not be so much exposed to the fire of 
the eneny.

used for the purpose of being made into

The second is also spun into yarn, which 
is dyed and used for the pile of the car- 
pets. The third sort is spun into a coarser 
yarn for the weft. . ‘The yarn forthe pile 
is dyed m the skams of various colours, 
and Mr. Paty claims as his invention the 
application of the art of dyeing towards 
imparting the said colours, and shades of 
colours, to the sun-hemp of India; for 
which purpose he makes use of the fol 
lowing materials, viz. cochineal, argol,
