PROVISIONAL SPECIFICATION.
Improvements in Night Lights.
We, JAMES DAMPIER PALMER, M.P., Chairman of Palmer and Company Limited,
of Victoria Works, Stratford, in the County of Essex, HENRY PALMER, Managing
Director of the said Company, and HENRY ERNEST TRESTRAIL, M.R.C.P., F.R.C.S., &c.
of 94 Woodgrange Road, Forest Gate, in the said County of Essex, do hereby
declare the nature of this invention to be as follows:-
The object of our invention is to diffuse disinfectants and perfumes more
effectually than this has heretofore been done by means of night lights; and this
without deteriorating the night lights as respects the illuminating value.
We do not mix the disinfectant or perfume with the fatty matter as is sometimes
done but we dispose the same in compartments so placed that they will be in such
proximity to the flame as to be heated and gradually evaporated whilst the night
light burns.
For the more volatile disinfectants and perfumes we provide the night light with
an outer case or jacket and the material to be evaporated is lodged between the two
cases, or the night light may be received into a case of rigid material as glass and
cavities may be provided in the sides of the case to contain the disinfectant or
perfume.
Less volatile matters we place in tubes of small bore and these we insert into holes
provided for them in the mass of fatty matter so that the tubes stand parallel with
the wick and at but a small distance from it. Being so arranged the tubes become
sufficiently heated whilst the fat around them prevents them from becoming so hot
as to damage their contents or to evaporate it too rapidly.

We, JAMES DAMPIER PALMER, M.P., Chairman of Palmer and Company Limited,
of Victoria Works, Stratford, in the County of Essex, HENRY PALMER, Managing
Director of the said Company, and HENRY ERNEST TRESTRAIL, M.R.C.P., F.R.C.S., &c., of
94 Woodgrange Road, Forest Gate, in the said County of Essex, 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 our invention is to diffuse disinfectants and perfumes more

page_text: effectually than this has heretofore been done by means of night lights; and this
without deteriorating the night lights as respects the illuminating value.
We do not mix the disinfectant or perfume with the fatty matter as is sometimes
done but we dispose the same in compartiments so placed that they will be in
such proximity to the flame as to be heated and gradually evaporated whilst the
night light burns.
For the more volatile disinfectants and perfumes we provide the light night with
an outer case or jacket and the material to be evaporated is lodged between the
two cases, or the night light may be received into a case of rigid material as glass
and cavities may be provided in the sides of the case to contain the disinfectant
or perfume.
Less volatile matters we place in tubes of small bore and these we insert into holes
provided for them in the mass of fatty matter so that the tubes stand parallel with
the wick and at but a small distance from it. Being so arranged the tubes become
sufficiently heated whilst the fat around them prevents them from becoming so hot
as to damage their contents or to evaporate it too rapidly.
Or we saturate blotting paper or other absorbent material with disinfectant or
perfume and cover the same with a coating of wax, this we wrap round the fat of
the night light. Evaporation of the disinfectant or perfume is prevented by the
coating of wax until it is melted by the heat of the burning night light.
The annexed drawings illustrate night lights made in accordance with this
invention.
Figure 1 is a plan and Figure 2 is a tranverse section of a night light for the more
volatile disinfectants or perfumes.
a is the outer case, and b is the inner case forming between them a receptacle for
the disinfectant or perfume.
Figure 3 is a plan and Figure 4 a transverse section of a night light for the less
volatile disinfectants or perfumes.
c is the fat, and d d are the tubes, attached to the base plate e, to contain the
disinfectant or perfume.
Figure 5 is a tranverse section of a night light with a wrapping of absorbent
material.
f is the outer case, g the absorbent material and h the fat.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is:-
1. A night light in which a disinfectant or perfume is embodied without being
mixed with the fat substantially as described.
2. A night light with compartments containing disinfectant or perfume, the
compartments being so placed that the disinfectant or perfume will be in such
proximity to the flame as to be heated and gradually evaporated whilst the night
light burns substantially as described.
3. The combination with a night light as an integral part thereof of a
piece of absorbent material saturated with disinfectant or perfume substantially
as described.
4. Night lights substantially as described.
