perpendicularly, and is kept in that per- 
pendicular direction by another piece, 
which performs two objects; for the inte- 
rior of it forms the catch-work of the 
screw, whilst the exterior is fixed by two 
screws on the pillar plate. The reader 
must be referred to the specification itself 
for a more particular description corre- 
sponding to the drawings attached to it. 
To elucidate the nature and superior uti~ 
lity of his invention, Mr. B. observes, 
First, That the old repeaters contain 
five wheels more than the’ common 
watches, besides five pinions and a barrel 
and main spring, which are all necessary 
to put the motion in action; they have 
also two hammers to distinguish hours 
from quarters. But the new repeater is 
composed of the common. plain move- 
ment and wheel-work, with the addition 
ouly of a hammer, which is placed in an 
insulated situation, having no communi- 
cation whatever with the wheel-work. 
Secondly, ‘The old motions being so 
very complex, are in their nature lable 
to be out of order from the slightest 
cause, because the chain of the motion 
which winds the main spring of the re- 
peating-work is easily broken by means 
of the pressure, its very structure, and 
its attenaant friction: and lastly, because 
the action of it depends upon the main 
spring and wheel-work, the latter of which 
is apt to be disordered, and the former 
shaps and breaks of itself. Whereas the 
new motion acts in itself, and has no de- 
pendance on wheel-work, or any other 
piece that is subject to be broken; an 
endless screw sets the two chief parts : 
in motion, which produces the effect of 
striking the hours and the quarters; and 
all the other pieces are designed only as 
collateral support to the principal ones. 
Hence the simplicity of construction in 
the new repeater, and a diminution. of 
expence. 
MR. ANDREW BRown’s (LONDON ,) for In- 
provements in the Construction of a 
Press for printing Books and_ other 
Articles, part of which may be applied 
to Presses im common use. 
These improvements are on the press 
itself: on the use of barrels or. cylinders 
for feeding the types with ink; and in 
the loose frisket and manner of using it. 
The press is made of cast iron, as is ‘also 
the bed which must be accurately faced 
for the types to lie on. A follower gives 
pressure on the types, and is fixed to the 
screw. In using this press the cast-iron 
bed slides out below the roller or cylin- 
der, which roller or cylinder revolves

round and feeds the types with ink. it 
is covered with flannel, or any other 
elastic substance, and then is covered 
with parchment or vellum, or other pro+ 
per materials to prevent the ink frona 
soaking too far in, and likewise to give it 
a spring, and afterwards is covered with 
superhne woollen cloth, for the purpose 
of receiving the ink to supply the types. 
There is a large barrel of cylinder, and 
also a smaller one: the former having 
received the ink from the trough under- 
neath it, the latter rolls on the other and 
distributes or spreads out the ink on the 
face of it;-or it may be necessary, with 
the smail barrel or cylinder, occasionally. 
to use a brush to distribute the ink, or 
lay the ink on the large barrel. The 
Jarge barrel feeds the other with ink, and 
that revolves and feeds the types by the 
motion of the ‘spindle, which moves the 
bed. Mr. B. is able to apply the barrels 
or cylinders, which he reckons his prin- 
cipal improvement, to presses now’ i 
common use, by means of a fly-wheel and 
traddle, which give motion to the two 
barrels or cylinders, and distribute the 
ink over the types, to feed them with ink 
either by the motion of the hand or fly- 
wheel, or by other methods well. known 
to every mechanic.

The pen is made of glass, enamel, or 
other substance capable of admitting a 
bore, the point is small and finely po-

large enough to hold as much or more 
ink than a common writing pen. The 
composition is a mixture of equal parts 
of Frankfort black and fresh butter, 
which is smeared over paper and rubbed 
off after a certain time. The paper thus | 
smeared 1s to be pressed for some hours, 
taking care to have sheets of blotting ai 
per between each of the sheets of black 
paper, . When fit for use, the paper 13 
put between sheets of this blackened pa-

on with common ink with the glass or
