lielief of Horses Fallen in Loaded Carts . 37 
cart, and is used in the event of the shaft horse fallings by 
hooking the traces of the other horses to a chain d, also 
iixed to the stanch eon ; the power of these horses, applied 
at this height above the fulcrum, will have a great pur- 
chase to elevate the shafts, and set the fallen horse at 
liberty, as is evident from an inspection of the figure. 
The staneheon moves on a joint on its lower end, and the 
oblique chain unhooks at the end can be connected 
with a short piece of chain e fastened to the last of the 
side rails ; the staneheon now takes the position of the 
dotted lines/, and the short chain, which hangs down per- 
pendicular from the end of it, may be taken hold of by any 
number of men, to weigh upon and raise the cart in cases 
where the horses cannot conveniently be applied ; the 
men will in this manner have much greater effect than 
merely (as is the common practice) weighing on the hind 
part of the cart. 
When the chain is completely detached, and the stan 
die on suffered to hang down perpendicularly, it forms a 
prop to support the cart steady while it is unloaded. It 
should be observed, that, though only one staneheon ap- 
pears in the figure, there are in fact two, one being placed 
on each side of the cart. 
Certificate. 
Mr. William Whitehead, jun. of Cadogan place, 
feloane street, certified, that he had attended experiments 
made to ascertain the efficacy of Mr. Smith’s invention ; 
that a cart weighing twenty-three hundred w eight, load- 
ed with one ton of stones, was raised by means of Mr 
Smith’s apparatus with ease by one horse. 
That he very much approves of Mr. Smith’s invention, 
and thinks it likely to be of great service in general prac- 
tice, more especially on account of the business being ef
