EBENEZER DIVER Yateley House Kenley Surrey Doctor in Medicine do hereby
declare the nature of this invention to be as follows:-
The introduction of elasticity into that part of an apparatus used by parturient
women which encircles the body & which is tightened thereon by the patient pulling
upon a cord. The encircling arrangement consists of a back- & a front-pad with a
running cord between them at either end to draw them together.
My improvement consists in so introducing elasticity that the pull is less docided
and harsh, especially upon the front-pad. The elasticity may be introduced at any
part of the circle, but the pulley arrangement at the ends of the front pad is con-
veniently placed for attachment to the material, giving elasticity, the other end of
which might be fastened to the pad itself.

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 introduction of elasticity into that part of an apparatus used by parturient
women which encircles the body and which is tightened thereon by the patient pulling
upon a cord. The encircling arrangement consists of a back-pad, a front-pad, & a
running cord between them at each end to draw the pads together.
My improvement consists in so introducing elasticity that the pull is less decided
and harsh in its effect upon the pads. The elasticity may be introduced at any part
of the circle; but the pulley arrangement at either end of the front-pad is conveniently
placed for attachment to the material giving elasticity, the other end or ends of which
would in this case be fastened to the pad itself in any convenient part. And it is in
this way that I prefer the elasticity to be given, but I do not confine myself to this
particular mode.
The pulley arrangement is such that the wheel rotates between two parallel plates
of metal having much the form of an isosceles triangle-the wheel being at the apex.
Near the base and parallel with it, the upper plate is bent and lies upon the other:
thus forming a solid margin to the triangle. This margin is perforated to allow the
passage of waxed thread for sewing the pulley arrangement to the front-pad of which
it then forms a part.
My plan is to sew the pulley arrangement to a piece of stout elastic of suitable
length &width, and to fasten the distant edge of the elastic to the before-mentioned
pad; so that the elastic will be interposed between the pulley arrangement and the
unyielding material which has hitherto alone formed the front-pad.
Thus when traction is applied to the pulley, the attached elastic will yield, and the
force be gently and gradually applied to the pad instead of more suddenly, as is the
case when elasticity does not intervene.
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:
The introduction of Elasticity in any part or parts of the encircling arrangement
of an obstetric apparatus having the character of approximation to the surface of the
body by traction as herein described.
