RELIEF OF IIORStS FALLEN IN LOADED CARTS. 329 



Reference to the Drazzin^ of Mr. Smith'' s Method of rats'* 

 ing up a Horse when fallen duzc7i in the Shafts of a loaded 

 Cart, Fig. 2, PL X. 



A is the wheel, and B ihc shafts of a cart, such as is used Explanation of 

 in London ; C the side rails; at the end of the body an iroa^^^'^^^* 

 stancheon or truss staff, a, is fixed by the hinge at the lower 

 end, and at the upper end it is supported by a chain 6, ex- 

 tended from the fore part of the body of the cart; this 

 diagonal -chain forms a firm support to the stancheon. 

 This is all the addition made to the common cart, and is 

 used in the event of the shaft horse falling, by hooking the 

 traces of the other horses to a chain d, also fixed to the 

 Stancheon; the power of these horses, applied at this height 

 above the fulcruni, will have a great purchase to elevate the 

 shafts, and set the fallen horse at liberty, as is evident from 

 an inspection of the figure. The stancheon moves on a 

 joint on its lower end, ^nd the oblique chain unhooks at d; 

 the end can be connected with a short piece of chain e fas- 

 tened to the last of the side rails; the stancheon now takes 

 the position of the dotted line«/, and the short chain, which 

 hangs down perpendicular 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 ap,. 

 plied; the men will in this manner have much greater efibct 

 than merely (as is the common practice) weighing on the 

 hind part of the cart. 



When the chain is completely detached, and the stan- 

 cheon sufiTered 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 stancheon 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 Testimonial, 

 place, Sloane street, certified, that he had attended expe- 

 riments made to ascertain the efficacy of Mr. Smith's in- 

 vention ; that a cart weighing twenty three hundred-weight, 

 loaded wjth one tun of stones, was raised by means of Mr,* 

 Smith's apparatus with ease by one horse. 



■yhat he very much approves of Mr. Smith's invention,
