PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Testing or Disinfecting Drains.
I, CHARLES THOMAS KINGZETT, F.I.C., of Elmstead Knoll, Chislehurst, in the
County of Kent, Chemical Manufacturer, do hereby declare the nature of this
invention to be as follows:
This invention relates to the class of apparatus in which a case containing some
material (such as phosphide of calcium or carbide of calcium, which emits smell
or smoke upon mere exposure or upon being wetted or it may be a disinfectant
material) is flushed past the trap and then opens either automatically or by the
action of running water.
According to this invention the case consists of an elastic ball having a hole
or holes in it through which the material is introduced and discharged. This
hole is closed by a cap preferably also lined with elastic material which is held
in place by winding string round it and the ball. The string slightly com-
presses the ball and forces it and the cap together with an elastic pressure so
making a tight joint.
As a further means of securing the contents of the case against possible
deterioration by atmospheric action, the hall when charged and bound is placed
in a suitable metal or other container the lid of which is rendered air-tight as
far as possible by means of a band of rubber or other material.
In using the apparatus the end of the string is held and the case is flushed
past the trap so unwinding the string and opening the case as has before been
proposed.

Improvements in Apparatus for Testing or Disinfecting Drains.
I, CHARLES THOMAS KINGZETT, F.I.C., of Elmstead Knoll, Chislehurst, in the
County of Kent, Chemical 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 relates to the class of apparatus in which a case containing some
material (such as phosphide of calcium or carbide of calcium, which emits smell
or smoke upon mere exposure or upon being wetted-or it may be a disinfectant
material) is flushed past the trap and then opens either automatically or by the
action of running water.
According to this invention the case consists of an elastic ball having a hole

hole is closed by a cap preferably also lined with elastic material which is held
in place by winding string band or the like round it and the ball. The string
slightly compresses the ball and forces it and the cap together with an elastic
pressure so making a tight joint.
As a further means of securing the contents of the case against possible
deterioration by atmospheric action, the ball when charged and bound is placed
in a suitable metal or other container the lid of which is rendered air-tight as
far as possible by means of a band of rubber or other material.
In using the apparatus the end of the string is held and the case is flushed
past the trap so unwinding the string and opening the case as has before been
proposed.
Apparatus made in accordance with this invention is illustrated in the drawings.
Figure 1 is an elevation of the container unopened, Figure 2 is a view of the
container opened and showing the tester and Figure 3 shows the ball when the
string has been unwound and the cap removed, the cap being shown in section.
The ball a has a hole b in it through which the phosphide of calcium or other
material is introduced and discharged. The hole 6 is closed by a cap c lined with
elastic material d. The cap is held in place by winding string round it and
the ball and is secured to the string by a layer of material f. One end of the
string is connected to the ball, and the other to the lid g of the container h.
When the ball is in the container a band of india rubber is placed over the
edge of the lid to render the container air tight.
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. Apparatus for testing or disinfecting drains consisting of an elastic ball
having a hole in it which is closed by a cap substantially as described.
2. Apparatus for testing or disinfecting drains substantially as described and
illustrated in the drawings.
