and allowing of the same standing, when 
quiescent, with the hammér/about’ onech 
fourth of. an inch distant from the bell: 
such mortice being sufficiently ‘long’ and 
wide, to allow of thehammer freely: striking 
the bell, after being drawn from it asufticient 
distance, forigiying the necessary impetus to 
the hammer, by;means.of the) notice-latch 
presently to be described. 
, The casing of, the bell is to be left open, 
for, letting.out.the, sound at that end, or 
side, the least, accessible to, any means of 
stopping. the sound of the bell, after the 
box-lid has been opened, 
The, notice-latch is of a construction 
nearly similar to the spring-latches which 
are placed on closet and cupboard doors, 
except that it has no handle, passing through 
the lid of the box; withinside of which lid 
it is to .be affixed, in such a position, that, 
on. shutting down, the, lid, the bevel of the 
latch may press, against, and pass down 
below,, the end of the hammer-spring, and 
on. the return. of the springs. to quiescence, 
may, rest just,,below, it, ready afterwards, 
on, the slightest rising. of, the; lid, to draw 
up, with. it the end. of the hammer-spring, 
and. on passing. off its. bevel, thereby give 
the impetus for striking, the bell,.and, giving 
the alarm, required. rm 
To us, this, appears a hasty and, ill. 
matured contrivance ; because, on the lid 
haying been quickly opened, and, the bell 
haying received a single stroke: from the 
hammer, the thief has only to place a finger 
on the end,of the projecting spring, and 
thereby press the hammer against the bell, 
and hold it there for an instant, to effectu- 
ally. prevent further sound from the bell. 
A competent artist, such as is now to be 
found in the counting-house or workshop, 
of a score or two of the mechanicians in, 
town, would find no difficulty in construct- 
ing a spring-alarum, inside of a strong-box, 
near to, and so securely connected with the 
hinges of its lid, that. the same could not 
be raised without. setting-off the alarum, 
which should. continue to ring for several 
minutes, without. the possibility of a thief 
stopping it, |
