other; but the end, after being put through the buckle, is 

 sewed down : this is for the purpose of security, in case the 

 tongue of the buckle should by accident break. 



6. The union strap F, so called from its connecting the re-r 

 gulator to the other parts of the machine. This is leathern, 

 and is about a foot and a half long and an inch and a quarter 

 broad : it has, like the others, a buckle to it. It is stained 

 black, which distinguishes it from the other leathern straps. 



The method of putting together all these parts of the ma- 

 chine is, first to pass one end of the rope through the holes 

 in the regulator, then through the two lower rings of the 

 suspension iron : the upper belt is then to be passed through 

 a doubling of the union strap; after which the rope is to be 

 tied to that belt, and the knot secured bv a string from slip- 

 ping (which string is to pass through two small holes in the 

 leather) ; and at about a foot below the rope is to be tied to 

 the lower belt in like manner. Next, the union strap is to 

 be put through the oblong hole in the regulator, and buckled; 

 by which the upper belt and the regulator will be connected. 

 The other end of the rope may be kept wound on a wooden 

 roller, to prevent it from getting entangled. 



Persons who purchase these machines should have a very 

 strong iron hook, with a spring-catch, fixed to some secure 

 part of the window-frame, or elsewhere ; on this hook the 

 suspension iron is to be hung by the upper ring, when any 

 one wishes to descend from the window. The next opera- 

 tion is to step into the lower belt with both feet, and draw 

 it up sufficiently high, so as to form a kind of swing to sit 

 in : the part of the strap which is through the buckle is to 

 be laid hold of with the left hand ; and the buckle, with the 

 right hand, is to be slipt to its proper place, according to 

 the size of the person : the tongue is then to l)c put into one 

 of the holes, a.-) in buckling conmion straps. After this is 

 done, the upper belt is to be somewhat loosely buckled round 

 the chest, and then the rope which is on the roller is to be 

 thrown out of window on the ground. 



Now all being ready for descending, the person is to get 

 out of the window, grasping tight, with one or with biuh 



hands.
