applied, besides protecting the leather 
to be glazed from being injured by * 
what are termed the blows of the rol- 
lers,” which create those indentations on 
the Jeather, which can seldom, if ever, be 
eradicated comptetely by any subsequent 
degree of exertion which may be devoted 
to the skin. The principles of this in- 
, vention may be reduced under thrée ge- 
neral heads: First, The facility with which 
any number of gazing rollers are made 
to traverse in one precise channcl; and 
the readiness with which an adjustment 
of all their parts is produced. Secondly, 
The table which supports the leather pos- 
sessing an- amplitude of discretionary 
ower to approach to, and recede from, 
the roller-shaft at pleasure, with the full 
power of resisting the pressure of the’ 
rollers at any given ratio, between the 
impeller and the retarder.  PhirdlysPhe 
application of an adjustable stop *te the 
table, whichy determines how near the ta- 
ble shall ach the rollers, and which 
furnishes a complete protection to the 
rollers and the leather against any effort 
of advance which may be directed to the 
table. 
In whatever way these properties or 
principles can be atchieved or obtain- 
ed, the patentees regard as their own in- 
vention,

in this manner we are told Jt- passes over 
all inequalities with yreat ease. And the

mangles with greater ease, performs its 
work better, and with more expedition 
than any before invented.

MR. CHARLES LUcas Brracn’s (GREAT 
QUEEN-STREET,) for ‘an Improvement 
in the Construction~of the Roofs of 
Carriages, the upper Parts of which 
are made to fall dawn, — | * 
Mr. Lucas deseribes the nature of his 
invention in ‘the following manner: 
Frame and fix in the top quarter rails to 
the tops of the standing pillars and slats, 
and fx the slats to the neck plates; rab= 
bit the inner parts of the standing pillars, 
the top quarter rails and the slats, and - 
board them with thin deals, or other 
proper material. L e€ crownepieces 
or cornice rails, be longstnough to level: 
or mitre into the corne top of the 
standing pillars; and let inthe hinges and 
thimble catches on the top of the crown- 
pieces, and top of the quarter rails. Vix 
-on the hoop sticks and back and front 
rails, and board them all up except the 
two hoop-sticks, which are nearest to the 
hinges, which may be placed as close as 
possible to admit of the head striking: 
conveniently low. Conceal or let inone 
or more boxed locks to the centre hoop 
if any. large irregular luinps ate formed ppiicks, or at. least the hoop-sticks 
by the linen rolied round the roller, 
band is put round all the rollers : hence, 
ca 
ite the'thimble catches, and fix them so 
as that they may be opened: by a key on 
when the top rolleris put in motion, it theimside of the carriage. Stretch strong 
will communicate motion to the two hot- 
tom rollers, and oblige the other roller to 
cunvas, or other fit material, and nail it, 
- , ‘ erwise fasten it, bath on the inside» 
act with them; sometimes a fly-wheel is and the outside of the slats and elb By 
fixed to the axis of the top roller, or a 
wheel with teeth on the axis of each of 
the bettomrollers, and one between them 
and sit betieen with flocks or tow, 
or other fit’ material. Likewise stretes, 
and nail on or fasten canvas, or any other: 
to connect them. Then the fly-wheel proper material, to the top hoop-sticks om 
may be put on the axis of either of those 
wheels: the fly-whcel to be on the op-" 
posite side of the machine to the handle. 
As a substitute for the platform and iron 
weights, a box may be suspended, in 
which SOMME, gravel, or any sub- 
stance may be placed to act as a weight. 
The utility ofthis machine is not confined 
“to mangling only, but may be used as a 
copper-plate printing-press, a letter co- 
pying machine, or a evlindrical press. 
#rom experiments, it appears te act best 
the roof which are nearest the hinges be- 
fore you put on the leather covering.”
