I, GERHARD BEUTHEL, Senior, of Alleestrasse 169, Barmen, Germany,
Bandage 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 :—
The truss forming the object of this invention serves to ensure that the pad may
always press exactly on the seat of the rupture and that it may readily adapt
itself to any movement of the body without causing the wearer of the truss any
pain owing to increased pressure while nevertheless the pad will always remain
situated at the exact place for which it has been adjusted.
The exact point of pressure on the pad itself can be adjusted at will.
In the annexed drawings two different modes of execution of the truss are
shown.
Fig. 1. shows a section through the pad.
Fig. 2. shows the pad viewed from above.
Fig. 3. shows the pad viewed from above after altering its adjustment.
Fig. 4. shows a section through the pad in the alternate style of execution.
Fig. 5. view of Fig. 4. from above..
Fig. 6. view of Fig. 4. from above after altering the adjustment.
The truss band A. fastens up by means of its coupling or ball-joint fastening B.
which is fastened into the socket or fastening piece D. on plate C. (at the other
end of the truss) so as to permit free rotary motion. For this purpose the socket
piece D. is fastened to the central part of plate C. by means of a swivel screw E.
In Figs. 2 & 3. holes F. are shown to be provided all round the fastening point
of the socket piece D, thus allowing free adjustment of the truss by shifting the
socket piece D, with the fastening knob B. which is of the shape of a ball somewhat
conical towards the lower end of the truss band A. fixed into it and fastening it to
the corresponding hole F. so that by simply unscrewing and screwing fast again
in the desired position the swivel screw E. the plate C. can be adjusted to any
desired position at an angle to the truss end A. varying from 0 to 360°. In order
to impart to the spring-pad G. a soft and uniform pressure variable within certain
limits two springs J and J₁ are fastened with screws to the slot or slide H. in such
a manner as to allow of adjustment. Slot H. is arranged concentrically to the
centre (E) of plate C. and the springs J and J' are held fast in any desired
position within the slot by means of the adjusting screws K K. The springs J
and J with their other end press against the spring-pad G. attached to the
plate C. by means of the hinge S, and hence according to the position given them
within (or with regard to) the slot will exert a gentle pressure upon the truss-pad.
After having put on the truss the pressure may be adjusted in accordance with the
condition of the rupture so that even one and the same truss may be used without
difficulty for persons of widely varying stature and for different kinds of ruptures.
Moreover the pressure of the truss-pad can be further adjusted according to the
size of the rupture-passage either for a certain point only or for a larger surface so
that the rupture-passage may be always kept closed to its full extent. Springs J
and may be selected and replaced by others as required so as to suit the
requirements of any given case. A spring X serves to provide an additional
elastic and soft connection between the truss-end A. and the pad G.
In the second style of execution illustrated in Figs 4, 5 & 6. instead of the
socket piece D. and the ball-joint catch B. a coupling-piece L-which is adjustable
in a horizontal (or rectilinear) position as well as revolving round the point where
it is fixed is used.

page_text: The fastening or connecting piece P. of the truss is joined to the coupling
piece by means of the screw O. In the slide or slot R. of the coupling
piece L. there is a screw h. by means of which the coupling piece is held fast in
position on the plate M. Hence the coupling piece L. can be fixed to the pad-
plate at any desired distance from the centre Q of the pad-plate by means of the
:screw O.
The arrangement of the spring is the same as described above.
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 :-
A truss arranged so as to render it possible to transpose the pressure of the
spring-pad to any desired point of its convex surface and so adjust it to any position
with regard to the rupture-seat, while at the same time securing the plate itself
against accidental shifting, such truss being characterised by having the truss-band
end A. attached to the plate C. of the spring-pad G. by means of a ball and socket.
joint. coupling B. (Fig. 1) which permits rotation round a fixed centre E.
(Figs. 1 & 2) and which can be adjusted at will into one out of a number of
holes F. arranged in a circle, while the spring-pad G. is connected with the plate
by means of a hinge-joint and is pressed against the rupture passage by
springs (JJ) which are adjustable as regard their position on the plate C. by
means of a slide or slot H.
