perch. The body is to be hung by the 
main braces, attached to these shackles 
on the springs, in the same manner as 
other carriage-bodies are usually hung. 
When the bedy is thus hung, the action 
is as follows; should either of the hind 
or fore wheels descend into a low spot 
in the road, or ascend a raised surface, 
the boxes or sockets on the body loops 
will turn on their axes, and keep the 
whole on a proper equilibrium, so as not 
to be overturned. 
Another part of the invention is the 
application of a cylinder to the collar- 
braces of carriages, by means of which, 
should the centre of gravity of the body 
of the carriage be moved by any inequa- 
lities in the road or otherwise, either to 
the right or left, the equilibrium will be 
almost immediately restored by the mo- 
List of New Publications.

tion of the cylinder or roller on its axis, 
and the consequent lapping and unlap- 
ping of the straps, for to whichever side 
the bedy is impelled, on that side will 
the collar brace be lengthened, and of 
course the opposite collar brace propor 
tionally shortened; one side is made to 
operate as a check upon the other, m 
order to bring the body to its true centre. 
The last part. of the invention 1s the 
perch-bolt, which being properly placed, 
the fore axle-tree bed may be turned 
either to the right or the left, with much 
greater ease than if the common perch- 
bolt were made use of, the usual fric- 
tion between the beds and wheel plates 
being almost wholly removed from their 
being gradually separated by the lifting 
of the screw in the act of turning.
