Tliere is attached to this specification, a 
drawing, which represents an oven that is 
twenty feet long and four feet wide, all 
tiie parts of which are particularly 
described, with the proportions. In 
smaller ovens the endless web may be 
jlispensed with, and the wire-cloth 
stretched upon a light iron frame of the 
length of the oven^ which with tiie bread, 
&c. placed upon it, is pushed in at the 
end farthest from the fire, and gradually 
advanced to the other, at which it is gra. 
dually withdrawn. By this method of 
baking, time, fuel,and labour, are saved, 
and other advantages are attained which 
are likewise enumerated in the specifica¬ 
tion. 
MR. RALPH . Wedgwood’s (oxford- 
street, LONDON), for a New Charac- 
ler for Language, NumberSy and Muuc, 
and the Method of applying the same. 
The archetype ol the character may 
be any regular figure, as a square, round, 
triangle, 6ic. or it may be a eombination 
of two or more such figures, hut the pa¬ 
tentee prefers one figure to a mixture of 
figures, because the parts of one figure 
are more than adequate to the v\anis of 
language, numbers, and music : and he 
prefers a square ro the other figures. The 
different parts of this square figure are 
made to signify all the various letters of 
the alphabet, figures, notes, and points. 
In printing, three types are made use of, 
one of which vvill make a line equal to 
the whole siile of the square figure, ano¬ 
ther making a line equal to one-half of 
fhe side of the square, to which is added 
■& point, and anotiier which makes aline 
equal to half the length of the side of 
the said square. We must refer to the 
specification for the particular shape and 
position of these three types, which are 
exiiibited by drawings annexed to it, and 
for other particulars which candot be 
explained without the aid of figures. 
To instruct a person in writing this 
character, a frame of metal with sijuare 
holes is used. The habit, of making 
square characters is soon attained ; and 
any writing perfoimed hy means of this 
rule has nearly the exactness of printing, 
and by its use all hand-writings are uni¬ 
formly alike. For musical notes choice 
is made of the simole horixonta! charac- 
A 
ter, which is printed or written on a stave 
of twelve coloured lines, each line re¬ 
presents a tone or Sc-mi-tone, and is suffi¬ 
ciently wide to receive the treble, tenor, 
and bass, parts on each line. The treble 
is put oil the upper part of the line, the 
tenor in the middle, and the bass at tlie 
lowest part thereof. The keys or strings 
of such instruments as vvill admit of itj 
are made of a colour to correspond w ith 
the lines on the music paper. 
MR. WILLIAM DOUGIIIY’s, (BIRMING¬ 
HAM,) for a Method of combining 
W heels for gaining Mechanical Forcers, 
This method of combining wheels mar 
be explained by the following description. 
.There is an immoveable or fixed wheel, 
a wheel of action or first mover, and two 
revolving wheels on loose centres or studs, 
which are screwed into an arm, which 
arm is pinned or wedged on an axle : the 
wheel of action has an arm or crank pin¬ 
ned on, by which it receives its impulse 
and works loose on the axle, and when in 
motion forces the revolving wheels round, 
pressing one downwards and the other 
upwards, and by this means removes or 
reduces the friction on tlieaxie. By this 
proportion of the diameters of the tour 
wheels, tlie power of four to one is ob¬ 
tained, the wheel of action making four 
revolutions to the axis. According to 
the power required must be the diameters 
of the wheels; that is to say, to obtain 
the power of seven, the wheel of action 
must be to the immoveable wheel as six 
to one, and the revolving wheels in pro¬ 
portion to the space between the other 
wheels. The motions or methods of 
working wheels, enables a person to ob¬ 
tain any power or velocity required in 
proportioning the wheels accordingly, 
and it may be applied to all engines, 
woollen, cotton, flax, hemp, threshing, 
and other machinery requiring a circular 
motion, as also to mills, lathes, grind¬ 
stones, windlasses, cranes, &c. and, by 
increasing the number of revolving wheels 
in proportion to the strands, it is ap¬ 
plicable for twine, rope, and cable, ma¬ 
chines, and other useful purposes. By 
this method the friction of machinery is 
considerably reduced; rendering it more 
portable and durable, less liable to acci¬ 
dents, .and less expensive.
