In some carriages he makes the seats 
to fold up into boxes by joining all the 
parts with hinges of metal or leather 5 
and proposes to attach these folding 
seats to carriages as additions, conceal- 
ed by folding together into shallow 
boxes.—Inrolled June, 1821. 
To THOMAS BonsoR CROMPTON, of 
Farnworth, Lancashire, for an Im- 
provement in Drying and Finishing 
Paper. 
This improvement consists in a mode 
of conducting the newly-formed paper, 
by means of endless or circulating feed- 
ing cloths, over heated cylinders, for 
the purpose of drying it more expedi- 
tiously. These cloths are proposed to 
be made hy the union of linen warp, 
and woollen weft. The machine, ap- 
plied to the purpose of drying and fi- 
nishing paper, consists of several revolv- 
ing hollow metal cylinders, mounted in 
an horizontal frame, and tu be heated 
by steam. The heated cylinders are 
turned by a series of spur-wheels, one 
upon the axis of each cylinder, with 
eog-wheels intervening, which take 
into teeth and connect the whole train ; 
the power for driving the train being 
communicated to any one of the 
wheels. 
Along the side of the machine is 
carried a steam-pipe, from which the 
steam is passed by cocks through the 
axles of the cylinders for the purpose 
of heating them. There are a number 
of small rollers, both above and below 
the cylinders. over which the feeding 
cloth passes, forming to each cylinder 
and its set of rollers an endless web, 
which receives the wet paper as it is 
first delivered, and conducts it round 
the series of drying cylinders. 
When the paper has arrived at the 
end of the machine it is discharged in 
a dry and finished state, and herea pair 
of shears or cutters are placed, for the 
purpose of cutting the paper as deliver- 
ed into sheets of any required length. 
There are screws connected to the lower 
rollers for the purpose of lightening or 
loosening the web, in the event of the 
paper expanding or contracting as it 
passes through the machine. The cut- 
ter attached to the end of the machine 
is put in motion by means of a tappet- 
wheel, or an excentric connected with 
the revolving train, by which the move- 
able blade is made to cut off the paper 
to any length regulated to the speed 
sueane tappet-wheel.—Inrolled April,

To Mr. MACNAMARA, for Improve- 
ments in Street Paving. 
This invention of Mr. Macnamara’s, 
proposes a new pavement, composed of 
stones 28 inches by 24, each supported 
and supporting two of the adjoining 
stones, and grooved so as to prevent 
horses from slipping. The pavement 
will be somewhat elevated in the 
centre, and the whole will be bound by 
kirb stones, so as to prevent the neces- 
sity of foundation. Mr. Alderman Wood 
has proposed that an essay of this pave- 
ment may be made in the ward of Crip- 
plegate, andjthat another shall be effect- 
ed in the neighbourhood of the Found- 
ling Hospital. We shall duly attend 
to these experiments, and acquaint our 
readers with the result. 
To JAMES HueeertT, of Hailsham, for 
a Drag, to regulate the Speed, and 
prevent Accidents in going down Hill. 
This invention consists of an appara- 
tus. placed under the carriage, which is 
intended to act asa drag, by pressing 
or rubbing against the ground when 
going down hill, or in any situation in 
which it may be necessary to retard 
the velocity of the carriage ; by which 
contrivance very considerable friction 
is produced, and the progress of the 
carriage accordingly impeded. 
The drag, which consists of a broad 
piece of iron, is placed under the perch 
of the carriage, between the hind- 
wheels, or elsewhere, as may be thought 
most convenient. This drag is intend- 
ed to be lowered, so as to come in con- 
tact with the ground, by the driver, 
without quitting his seat, or by any 
other person upon the coach-box or else- 
where, and raised again by a similar 
operation. It is to be worked by a 
winch or handle, near to the coach-box, 
or, if preferred, at the hinder part of 
the carriage. 
When the carriage is standing by, 
out of use, it may be desirable to draw 
up the drag close under the carriage, 
which may be done by unhooking the 
chains. This new-constructed drag is 
applicable also to waggons, and may be 
moved by a winch and pinion behind 
the waggon. 
This improved drag may be also ap- 
plied to light carriages of every descrip- 
tion, by various modifications of its at- 
tachments, arising out of the peculiar 
construction of such carriages. 
The following are some of its advan- 
tages: 
First. The driver is enabled, without
