-NEW PATENTS AND MECHANICAL INVENTIONS. 
—<p~_—_ 
To Mr. Mattuew Busn, of Battersea 
| Pields, Surrey; for an Improvement 
“on a Machine now in use, for Print- 
ing Silks, Linens, Woollens, Sc. 
HIS is an improvement upon a 
, printing apparatus, for which 
Mr. Bush obtained a patent in January 
1813. In that patent, the improve- 
ment upon the ordinary press, with 
copper-plates, employed for printing 
silks, linens, calicoes, and woollens, 
consisted in the introduction of one or 
more “reyolving pieces, which carry 
circular faced blocks, for printing.” 
The present improvement consists of 
the substitution of flat faced blocks, 
on which the subject in relief is to be 
cut, for the purpose of printing two or 
more colours, and also for the employ- 
ment of copper-plates in a different 
manner to that hitherto practised. The 
patentee states, that this invention is 
applicable to common copper-plate 
printing-presses, now in use for the 
printing of silks, linens, calicoes, 
- woollens, &e. and that, by means of 
this improvement, shawls and handker- 
chiefs, with borders, can be printed in 
the same machines, with great rapi- 
dity, by taking successive impressions 
from two narrow copper-plates, which 
are to be attached to the moving car- 
riage or rail of the press. 
The first part of the invention con- 
sists in the manner of applying the 
two copper-plates. That plate which 
is to give the pattern of the interior 
part of the shawl or handkerchief, is 
proposed to be in breadth one-fifth of 
the size of the handkerchief, within the 
border, and as long as the handker- 
chief is wide, including the border; 
the corresponding fifth parts of which 
are to be engraved at its ends. This 
plate is intended to produce the com- 
plete internal pattern, at five succes- 
Sive impressions; and the second 
plate, which contains the border only, 
is intended, by sliding the carriage 
forward, to occupy the place of the 
last, and complete the impression or 
pattern, by giving the border. The 
border plate is made to turn round ho- 
rizontally upon a pivot, so as to give 
the border in the reverse direction for 
the commencement of the next hand- 
kerchief; after which, the carriage is 
slidden back again, and five succes- 
sive impressions taken from the first 
plate, as before described, for the in- 
ternal pattern of the handkerchief. 
The second part of the improvement 
consists in the manner of applying the 
flat block to print or ground another 
colour. This block is suspended by 
levers, and is brought in contact with 
the
