Complete Accepted, 15th Feb., 1887,
I, EDWIN DODD of Gothic Villa West Green Road Tottenhamn in the County of
Middlesex Surgical Instrument Manufacturer do hereby declare the nature of this
invention to be as follows:-
The improved pessary consists of a spring ring made of watch spring covered with
india rabber as in the ordinary watch spring pessary and this spring ring is enclosed
in an outer hollow ring of india rubber inflated with air.
The improved pessary possesess all necessary softness and pliability, is easily intro-
duced and assumes its position without trouble, in embracing the whole circumference
of the vagina it does not scratch the walls or soft parts but readily yields to any
exertion of the patient at the same time steadily resisting any misplacement of the
uterus-it gives great support without friction and support without pressure and in
these two last respects it is totally different to all other kinds of pessaries introduced
into the vagina which by their hard unyielding nature cause great irritation and often
great excoriation,

page_text: I, EDWIN DODD of Gothic Villa, West Green Road, Tottenham, in the County of
Middlesex, Surgical Instrument Manufacturer, 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:-
This invention has for its object an improved pessary.
In my improved pessary I employ a ring of watch spring covered with india rubber
and this is enclosed in an outer hollow compressible ring of india rubber.
The annexed drawings show a pessary as I prefer to construct it. Figure 1 is a
plan, figure 2 is a transverse section on the line 1, 1 in figure 1. Figure 3 represents
the pessary in process of manufacture.
a a is a ring consisting of two or three convolutions of steel watch spring bound
together with a thin binding wire lapped around them in an open spiral. The watch
spring ring is first enclosed in india rubber. is a tubular or hollow ring of india
rubber loosely filled with cotton wool or other soft fibre which in conjunction with
the air which the tube contains supports its sides from within and causes the ring to
keep its form although yielding to a light pressure. The ring is attached by cement
to the exterior of the covered watch spring ring. e is a ring or casing of india rubber
enclosing a and 7. The india rubber to form this ring or casing is first made to a
cylindrical form as it is represented in Figure 3 it is inserted through the interior of
the spring ring and is attached to it by cement. A filling of cotton wool c' is then
inserted and the india rubber clapped over the whole and its edges joined to complete
the pessary as represented in figures 1 and 2.
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. A pessary in which a metal spring covered with india rubber is enclosed in an
outer hollow ring of india rubber substantially as described.
2. A pessary substantially as described and represented in the annexed drawings.
