PROVISIONAL SPECIFICATION.
Improvements in Disinfecting Apparatus.
I, JAMES ROBERTSHAW of 3 & 5 Simpson Street, Manchester, in the County of
Lancaster, Machinist, do hereby declare the nature of this Invention to be as
follows:-
It consists in certain improvements in apparatus for disinfecting premises or rooms
by means of the fumes of burning sulphur alone, or sulphur fuines and other dis-
infectants in combination.
To carry this into effect, I melt a suitable quantity of prepared sulphur into small
vessels of tin or other suitable metal or material of small value and easy portability
so that the sulphur can be easily transported from place to place set fire to and left
burning. In combination with this when necessary we use a vessel of suitable form
in which is placed a suitable quantity of carbolic acid or other disinfectant. This
vessel stands or is suspended over the burning sulphur, the heat of which causes the
carbolic acid or other disinfectant to give off the necessary fumes.
Dated this 15th day of December 1887.

page_text: I, JAMES ROBERTSHAW of 3 & 5 Simpson Street, Manchester, in the County of
Lancaster, Machinist, 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:-
It consists in certain improvements in apparatus for disinfecting premises or rooms
by means of the fumes of burning sulphur alone, or sulphur fumes and other disin-
fectants in combination. Heretofore a great obstacle in the free use of sulphur for
disinfection has been the difficulty of burning the same without risk and with case.
One part of my invention consists in melting a suitable quantity of prepared
sulphur into small pans or vessels of tin or other suitable metal or material of
sufficient strength to prevent the injury of the surface upon which it is placed, and
yet of small value, and easy portability and which can be ignited and left burning.
The second part of my invention consists of a suitably shaped vessel of metal or other
suitable material which may be used in combination with the tins or pans of sulphur
mentioned above, and in which the heat of the burning sulphur vaporizes some other
disinfectant or disinfectants such as carbolic acid. This vessel I form preferably
with two compartments (more if more than two disinfectants are used) one to
contain the tin or pan of burning sulphur and the other to contain the disinfectant it is
desired to vapourize. In order that the foregoing may be better understood, I send here-
with a sheet of Drawings in which are shown (in section) two forms of the apparatus.
In Fig. 1, a indicates the burning sulphur, b the vessel, the lower part of which
is made double so as to form the chamber c, into which the liquid disinfectant is
poured by means of the opening or spout d, from which also the fumes from the
liquid disinfectant issue. In Fig. 2. e indicates the burning sulphura tray or pan
in which is placed the disinfectant it is desired to vapourize the fumes of the two
disinfectants iningling in the outlet.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1st. Small tins or pans of sulphur, substantially as described and shown herein-
before and in the accompanying drawing for the purpose set-forth.
2nd. Vessels or apparatus for utilizing the heat of burning sulphur for vapourizing
other disinfectants, substantially as described and shown hereinbefore and in the
accompanying drawing for the purpose set-forth.
Dated this 15th day of September 1888.
