IMPROVEMENTS IN TRUSSES
Year: 1876

page_text: LETTERS PATENT to Emil Edel, of Berlin, Prussia, in the Empire of Germany,
Doctor of Medicine, for the Invention of "IMPROVEMENTS IN TRUSSES."
PROVISIONAL SPECIFICATION left by the said Emil Edel at the Office of the
Commissioners of Patents on the 20th May 1870.

"IMPROVEMENTS IN TRUSSES."
This Invention has for its object improvements in trusses.
Hitherto many disadvantages have been coupled with the use of trusses manufac-
tured with a rigid iron, steel, or other metal spring which from its unremitting
pressure is attended not only with detrimental results but frequently with disastrous
consequences to the wearer.
Now I propose to obviate such disadvantages by substituting for such metal spring
a carcanet-like elastic chain made of any suitable metal and formed in separate links,
such links fitting together and lapping over each other somewhat in the manner of
tiles. The links are joined to each other by means of rivets or any other suitable
fastenings so arranged as to allow of the easy play in a horizontal position of the
various links constituting the chain. In order to prevent the displacement of any
of the links from such horizontal position, and at the same time to ensure their
fitting the body of the wearer in a uniform manner, I connect such links together
by means of tongue-shaped projections formed in each of such links and so arranged
that each of the projections on one link fit into the next by entering a slot formed
therein, which thus ensures the chain setting flat at the same time that it remains
perfectly flexible. I cover such chain with leather or any other suitable material in
the ordinary manner.
The advantages of my improved truss are that while fitting uniformly to the
body of the wearer it causes a sufficient but not too rigid pressure upon the parts
affected, at the same time that its perfect elasticity not only allows it to yield to
every movement of the wearer but also permits of its being drawn entirely
flat without any risk of breaking by means of a tongue and buckle, or any other
suitable fastening, and thus renders it extremely commodious to the wearer.
