Complete Specification Left, 9th Sept., 1898-Accepted, 12th Nov., 1898
PROVISIONAL SPECIFICATION.
An Improved Hernia Truss.
I, Robert RichaRDSON, of 31, Moray Place, in the City of Dunedin, in the
Colony of Now Zealand, Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:-
-
The object of the invention is to produce a truss, the pad or pads of which
shall press against the part of the body required in the usual way, but at the
same time the pads or any of them, when more than one are used, may be
adjusted to any required pressure, more pressure being put on by mere pressure
from outside at any moment. This is effected by forming the parts of the main
belt near where the truss pads are required, of round section carrying a fixed
ratchet wheel, or part such as a segment of a wheel.
The pad ends where it joins the belt in a bearing round the round part and
a pawl to engage the ratchet teeth.
Referring to the accompanying drawing:-
Figure 1, is an end section through the part of the belt that carries a pad.
Fig. 2, is an elevation of the same part showing the arrangement of the working
parts, and Fig. 3, shows a convenient fastening for the belt.
A, is the belt to extend round the body or other convenient part of same, A¹
the rounded part carrying the ratchet or part of ratchet wheel B.
C, is any conveniently shaped pad plate which would generally be covered in
the usual manner.
D, is a spring and pawl or a spring pawl engaging the teeth of B.
E, is the strap of the belt and F, a bent ball pointed hook as a convenient method
of securing the belt without a lump showing as usual with most buckles.
This ball pointed hook is also suitable for general belt fastening or the like.

An Improved Hernia Truss.
I, ROBERT RICHARDSON, of 31, Moray Place, in the City of Dunedin, in the
Colony of New Zealand, Mechanical Engineer, 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 object of this invention is to produce a truss, the pad or pads of which shall
press against the part of the body, required, in the usual way, but at the same

page_text: time the pads or any of them when more than one are used, may be adjusted to
any required pressure from the outside at any moment. This is effected by
forming the parts of the main belt near where the truss pads are required of a
round section carrying a fixed ratchet wheel or part, such as the segment of such
a wheel. Where the pad joins the belt it ends in a bearing fitting the round part
already alluded to, and has a pawl for engaging the teeth of the ratchet, so that
any extra pressure given is retained.
Referring to the drawing filed with the Provisional Specification, Figure 1
is an end section through the part of the belt that carries the pad. Also 'part of
the fastening strap. Figure 2 is an elevation of the same part showing the arrange-
ment of the working parts, and Figure 3 shows a convenient fastening to the 'belt
for engaging holes in strap. A is the belt made to extend round the body or other
convenient part of same, and A' is the rounded part for carrying the ratchet
teeth of B.
C is any conveniently shaped pad plate which would generally be covered in
the usual way. D is a spring and pawl for engaging the teeth of B. E is the
strap of the belt and F is a bent ball pointed hook, as a convenient method of
securing the belt, with as little as possible of a lump showing being less than
most buckle fastenings.
It is obvious that this bent ball hook is also suitable for any kinds of belts,
other than for this truss fastening.
This invention may be made in any suitable materials or of any convenient
sizes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In a hernia truss, the combination of the ratchet and pawl movement (such
as B, D) so that a pad (such as C) secured to a belt (such as A¹ A) is rendered
easily adjustable and capable of being tightened up when in use from the outside
of the clothing, the whole substantially as described and illustrated in the
drawings accompanying the Provisional Specification.
2. In a hernia truss, the combination with the truss, the bent ball hook, and
row of holes to be used as a fastening (such as F E) substantially as described
and for the purposes specified.
