COMPLETE SPECIFICATION.
An Improved Apparatus for Disinfecting Water Closets, Drains,
Sewers, and such like.
We, WILLIAM AUGUSTUS WOOD & HERBERT HOBDEN both of 14 Wellington
Street Woolwich Tin Plate Workers, 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 :-

junction with flush cisterns, connected to water closets, drains, sewers, etc., consisting
of container for holding the disenfectant and a small chamber to which is connected.
an air tube and a syphon so arranged as to supply a small quantity of the disen-
fectant at each flush.
Referring to the annexed drawing
Figure 1. is a sectional side elevation of our invention in position in a cistern.
Figure 2. plan of our invention.
a is an outer casing in which the disenfectant is placed through the aperture
covered by screw cap b. c is an inner chamber connected to the outer air through
the tube e. This inner chamber c is in communication with the casing a through
the aperture f g is a syphon which communicates with the inner chamber c.
is the ordinary cistern. j outlet to same.
The action is as follows:-

When the cistern is being emptied, the syphon g begins to act as soon as the
water in the cistern reaches the level i. The syphon g now empties the casing
& inner chamber, the contents falling into the cistern & mixing with the
remaining water in same. When the cistern fills again the water enters the
casing a & inner chamber c through the syphon g. The casing a is only partially
charged with water at each operation owing to the air contained in the casing a
which prevents the same from being fully charged; & it will be seen that the
quantity of water or liquid impregnated with disenfectant which is discharged from
same will depend on the relative sizes of the casing a & inner chamber & also upon
the depth of the water or liquid in which the apparatus is placed. It will also be
seen that by dipping the apparatus into a vessel of water or liquid and withdrawing
