Foot and Ancle, there project Two Arms from the 
Sides of this Sole-plate, to which the Strops coming 
from the Ancle-band are faftened. That the whole 
Limb may be kept in a Line with the Machine, the 
Leg is fufpended by Bands, one of which is placed at 
the Ancle, from the Sides of which pafsTwo Strops, 
to join the inferior Knee-band: From this Band pafs 
Two Strops to the fuperior Knee-band: All thefe 
Strops are defigned to divide the Extenfion, fo that all 
Parts may equally bear alike, and fo to fecure the 
Joints of the Limb from the Violence of the Exten- 
sion. The Infide of thefe Strops are lined ; the Bands 
incircling the Limb are contrived in the fame Man- 
ner as the Bow or Spring of a Trufs, having ftrong 
Clafps at the Ends, after the Manner of thofe for 
Pocket-books, to fit any Dimenfions. The Band, 
embracing the Part above the Fra&ure, and from 
which pafs Two Strops to the Head of the Bed, to 
make the Counter-extenfion, is of the fame kind as 
the former, and is to be kept on, the whole Time of 
Decumbiture, to prevent the Patient's Body finking 
on the Fra&ure, and thereby contra&ing the Limb. 
The exterior of the Two laft-mentioned Strops prelfes 
juft beneath the great Trochanter on its Outfide; the 
other comes from the anterior Part of the fame Band, 
and in fuch a Scite as to give the Patient Liberty to 
raife himfelf at Difcretion. To preferve the natural 
Curvity of the Thigh, it would be neceffary to have 
a large broad Band arifing from the Bedfide, to en- 
compafs the frattured Part, and keep it fteady.
