IMPROVEMENTS IN APPARATUS FOR DISINFECTING WEARING APPAREL BEDDING AND SUCH LIKE
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
We, THOMAS JENNINGS of 46 York Road Lambeth in the County of Surrey.
Builder & Decorator and GEORGE CASE of French Yard Guinea Street Bristol
in the County of Gloucester Engineer do hereby declare the nature of our
Invention for "IMPROVEMENTS IN APPARATUS FOR DISINFECTING WEARING
APPAREL BEDDING AND SUCH LIKE" to be as follows:-
The object of the Invention is to provide a simple and efficient apparatus for
disinfecting wearing apparel, bedding, and such like.
The apparatus is composed of an iron box covered with asbostos to prevent
oscape of heat and an inner box of less depth and of less width at the bottom. At
the top the sides of the inner box may be made to meet the sides of the outer box
so that the spaces between the inner and outer boxes taper from top to bottom.
Through the upper part of the sides of the inner box numerous small orifices are
formed. Gas jets are placed below the bottom of the inner box, the heat from
which is dispersed round the sides of the inner box and then into its interior
through the above mentioned orifices so that a uniform heat is obtained throughout
all parts of the interior of the inner box.
The top of the inner box is closed over by lids and a chimney with valve is
provided by which vapours may be conducted away from its interior. Atmospheric
burners are used so as to avoid the production of any smoke.

Builder & Decorator and GEORGE CASE of French Yard Guinea Street Bristol in
the County of Gloucester Engineer do hereby declare the nature of our Invention
for "IMPROVEMENTS IN APPARATUS FOR DISINFECTING WEARING APPAREL BEDDING
AND SUCH LIKE 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 the Invention is to provide a simple and efficient apparatus for
disinfecting woaring apparel bedding and such like.
In the Drawing hereunto annexed we have shewn various views of apparatus
constructed according to our Invention.
Figure 1 is a longitudinal section Figure 2 a cross section Figure 3 a plan and
Figure 4 a perspective view partly in section of the apparatus.
It is composed of an outer non conducting casing A which may be of iron covered
with asbestos and also of an inner box B of less depth and of less width at the
bottom. The top of the inner box is secured to the top of the outer box and
numerous holes B³ are formed through the upper part of the sides of the inner box
as shown,
Burners C for burning a mixture of gas and air are placed below the bottom of
the inner box. The way in which wo prefer to effect an admixture of air with the
gas before it issues from the burners is shewn at Figuro 5.
The gas supply pipe is made to terminate in a nozzle which protrudes a distance
into the open end of the inlet to the burner so that the gas as it issues from the
nozzle may draw air along with it into the burner when the gas jets are lighted the
heated products of combustion arising from them heat the bottom of the inner
box and rising up through the spaces between the sides of the inner and outer
boxes pass through the holes B' into the interior of the inner box and pass away
from the bottom of this box through a chimney or ventilating shaft D. A complete
circulation of heated air is in this way maintained and the whole of the interior of
tho inner box becomes very uniformly heated with a moist heat. The inlet to the
chimney is provided with a valve which can be opened or closed as desired by
means of a rod D'. The out draught from the inner box can so be regulated or
entirely shut off for a time if desired.
E. E are lids by which the box is closed over at the top. At Figure 2 we have
shown that they may have counterbalance weights El secured to them if desired so
that they may the more readily be raised.
Fare rods placed across the interior of the inner box-they form a grating upon
which the fabrics or articles to be disinfected may be placed. G are other rods
which may be used as supports for mattresses and such like articles so as to allow
of their being stood up edgewise to permit the heated air to circulate froely
around them.
H is a grating placed just above the bottom of the inner box-upon this grating
also any articles which are to be disinfected or dried may be placed.
Apparatus constructed as above described is well adapted not only for disinfecting
wearing apparel or bedding or furs or skins or such like but also for drying and
airing.
It can be heated very rapidly and the heating is always very uniform throughout
the whole of its interior. In about three quarters of an hour to an hour the whole
interior of the apparatus and the bedding or other articles placed in it can bo raised
to about 300° Fahrenheit without any risk of burning.

page_text: This temperature is several degrees above that required to destroy oven the ova
of insect life.
A second quantity of bedding or wearing apparel could be purified in much less
time.
The apparatus can be made of any desired dimensions. It may if desired be
made large enough to admit of articles of furniture such as sofas and chairs being
placed in it. In this case it may advantageously be made to open at one side in
place of at the top. Where gas cannot be made use of for heating the apparatus it
may be heated by burning petroleum or other oil.
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
wo claim is :-
The combination of apparatus consisting of an outer casing A an inner casing B
having burners placed below its bottom and holes formed through the upper parts
of its sides and also of an outlet flue or chimney led away from the bottom of
the inner casing substantially as herein before described.
