New Copying-Press. 201 
I have had tent-poles, travelling trunks, baskets covered with 
painted leather, and other articles, in constant tear and wear for 
years, in w’hich, from its cheapness, this mode of ornamenting 
had been very liberally applied, and have often had occasion to 
remark the power which it appeared to have of resisting t}ie ef- 
fects of the weather. 
On a first trial, sp^e littlp difficulty of manipulation may be 
found, in bringing the tin to a sufficiently impalpable powder, 
and aJsP in hitting the proper quantity of glue to be put in. If 
the size be too strong, the agate has no effect ; and if too weak, 
the tin crumbles off under the burnishev. A very little practice 
will utake tjie process exceedingly easy. 
% Account of a New Copying-Press. Communicated by the 
Inventor. 
The following description of a very simple and ingenious 
new copying-press, has been transmitted to us by a correspon- 
dent, by whom it has been constructed and used. 
In Plate X. Fig, 1. AB are the upper and under boards, 
of two inch hard wood, well seasoned. The axle CD is laid 
along the centre of the under side of the lower board, through 
the supports . EF, and is seen separately at G. The one copied 
from is made of f th inch bar-iron, having notches HI at each 
end, filed down on one side only, and rounded to | tbs of an inch 
in diameter. In these notches, the round heads of the bolts KL 
work ; each of these being screwed, with a strong nut MN, for 
adjusting to different thicknesses of books. The upper board 
is raised, when the pressure is taken off, by the pieces of spiral 
spring-wire OP, each of which is sunk into a large bore, about 
half through the under board. The nuts MN press upon pieces^ 
of iron sunk into the upper board. The whole is supported on 
three feet, not represented, to avoid confusion. With a handle 
of nine inches, a pressure of from two to three tons can very 
easily be given. The application of this axle to the rollers of a 
lithographic-press, or even to. the common printing-press, must 
be evident to any one, while it is capable of being constructed 
by the most common artificer.
