PROVISIONAL SPECIFICATION.
Improvements in Surgical Trusses.
I, JOHANN HEINRICH LUCAS, of Güstrow, Mecklenburg, in the Empire of
Germany, Truss-maker, do hereby declare the nature of this invention to be as
follows
My invention relates to surgical trusses.
In the trusses heretofore used the pressure of the pad is mostly produced through
the medium of a bow spring which forms part of the belt. Such a spring extending
around the hip, by reason of the pressure it exerts causes inconvenience to which
many persons do get accustomed, and also interferes with the circulation of the
blood. To obviate these defects I employ a truss having a pad with three adjust-
able springs pivoted at one of their ends to a common pin on the pad. Of the
other ends of these springs two are secured to the belt bands and the third to the
extremity of an auxiliary supporting band. Whilst hitherto the pad has been
included only between the two ends of the belt, in the improved truss it is held
between three bands.
The aforesaid three springs are arranged radially on the back of the pad and
pivoted upon a common pin. They are bent outwards, and each carries at its free
end a knob fitting into holes at the ends of the belt and auxiliary band. These
springs are placed at an angle to each other and as they can be turned they may
be put in a position corresponding to the body. For this purpose one end of the
auxiliary band is adapted to be displaced on the belt. The pad may be of any
desired form, and the springs may be connected with the ends of the belt by means
of buckles.
Trusses may be provided with two pads of the above described kind which are
combined for a double rupture. In this case two springs, that is to say one of the
three springs of either pad, are combined to form a single spring for connecting
the two pads. A truss having two pads is applied in a similar manner as a truss
with one pad.
As in the above-described trusses the pressure is exerted from three sides, by
reason of the employment of the auxiliary band, the pad is held very securely in its
place. The belt and auxiliary band may be elastic, more or less broad, and
finished in any desired manner.

COMPLETE SPECIFICATION.
Improvements in Surgical Trusses.
I, JOHANN HEINRICH LUCAS, of Güstrow, Mecklenburg, in the Empire of
Germany, Truss-maker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to surgical trusses.
In the trusses heretofore used the pressure of the pad is mostly produced through
the medium of a bow spring which forms part of the belt. Such a spring extending
around the hip, by reason of the pressure it exerts causes inconvenience to which
many persons cannot get accustomed, and also interferes with the circulation of the

able springs pivoted at one of their ends to a common pin on the pad. Of the
other ends of these springs two are secured to the belt bands and the third to the
extremity of an auxiliary supporting band. Whilst hitherto the pad has been
included only between the two ends of the belt in the improved truss it is held
between three bands.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a view of one form of my truss adjusted in position.
Figure 2 is an enlarged view of the same.
Figure 3 is a detail thereof.
Fi
Figure 4 is a view of another form of my truss in position and
Figure 5 is an enlarged view of the same.
Referring to Figures 1 to 3 a is the pad, c springs which are arranged radially
on the back of the said pad and pivoted upon a common pin b. They are bent
outwards, as shown in Figure 3, and each carries at its free end a knob c which fit
into corresponding holes at the ends of the belt d and auxiliary band e.
The pad
is applied in the manner shown in Figures 1 and 2. These springs are placed at
an angle to each other, and as they can be turned they may be adjusted to any
position to suit the body. For this purpose one end of the auxiliary band e is
adapted to be displaced on the belt d. The pad may be of any desired form, and
the springs c may be connected with the ends of the belt by means of buckles.
As shown in Figures 4 and 5 the improved trusses may be provided with two
pads of the above-described kind which are combined for a double rupture. In
this case two springs c that is to say one of the three springs of each pad are
combined to form a single spring C for connecting the two pads. A truss having
two pads, is applied in a similar manner as a truss with one pad, see Figure 4.
As in the above-described trusses the pressure is exerted from three sides, by
reason of the employment of the auxiliary band e, the pad is held very securely in
its place. The belt d and auxiliary band e may be elastic, more or less broad, and
finished in any desired manner.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. A truss in which the belt spring, is dispensed with and in which the two
ends of the belt d and the free end of the auxiliary band e are each connected with
one of three springs c, which springs are pivoted upon a common pin 6 of the pad a
and made adjustable as described with reference to Figure 2.
Second. The combination of two pads of the kind above described by the use of
the connecting spring C which is adapted to replace one of the springs c of each of
the two pads as shown in Figure 5.
