IMPROVED DISINFECTING APPARATUS
Year: 1885

page_text: I THOMAS BRADFORD of Crescent Iron Works Salford in the County of
Lancaster Engineer do hereby declare the nature of my invention for IMPROVED
DISINFECTING APPARATUS to be as follows:-,
This invention consists partly in improvements on certain portions of a disinfecting
closet or apparatus for which I obtained Letters Patent dated February 18th 1884
N° 3455, and in an improved form of conveyance to be used in connection there-
with for collecting infected articles, from the surrounding district and conveying
the same with safety along the high roads and delivering them to, or depositing
them in the said disinfecting closet.
In the first place my improvements relate to an improved construction of the
evaporating tray (marked m, m on the drawings of the Specification of the Patent
above referred to) the edges of which I now bend inwards at an angle instead of
bending them over in a curved form, which I find to be more efficacious in
preventing the water from boiling over.
Secondly I place above the evaporating tray a baffle plate, composed of cast iron
or other suitable metal covered with asbestos or other suitable non-conducting
substance, for the purpose of preventing the direct vertical evaporation and
radiation of heat and vapors and giving a sideways direction to the steam
evaporated by the boiling tray, and so as to direct it towards a point immediately
above the open ends of the cellular bars whereby scorching of the articles is
prevented.
Thirdly I arrange a cistern and ball tap in connection with the apparatus so as
automatically to keep the water in the evaporating trays always at the desired
level, so that it is self regulating.
Fourthly I propose to use in connection with this apparatus a conveyance
consisting of an inner and an outer chamber; the former being a case or receptacle
for the infected articles and the latter a conveyance fitted with wheels for
locomotion.
The latter is open upon one of its sides or ends only (preferably at the back) for
the admission of the inner case or receptacle which slides in a telescopic fashion
into the outer chamber or conveyance, being fitted with small friction rollers for
that purpose. The inner chamber or case is closed at that end or side which is left

page_text: open in the outer chamber or shell also at the top and bottom, having openings
either at the ends or at the opposite side, so that when it is filled with the articles
to be disinfected and pushed into the outer shell or conveyance it forms its own
door and effectually closes the same.
The, inner chamber may be fitted with removable carrying bars which may be
employed also as shafts for moving the conveyancé from place to place.
It must be understood that upon the arrival of this collecting carriage at the
disinfecting house, it can either be enclosed bodily in the disinfecting apparatus,
and disinfected or the inner chamber or case with its open ends or side can be
removed and disinfected with its contents; or the contents of the inner chamber
can be removed and replaced upon the wagon which forms part of the apparatus.

'I THOMAS BRADFORD of Crescent Iron Works Salford in the County of
Lancaster Engineer do hereby declare the nature of my invention for "IMPROVED
DISINFECTING APPARATUS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:--
This invention consists partly in improvements on certain portions of a disin-
fecting closet or apparatus for which I obtained Letters Patent dated February 18
A.D. 1884 N° 3455, and partly in an improved form of conveyance to be used in
connection therewith for collecting infected articles from the surrounding district
and conveying the same with safety along the high roads and delivering them to
or depositing them in the said disinfecting closet.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the two sheets of drawings hereunto annexed and the following explanation
thereof.
On Sheet 1. Fig. 1 is a detached section of the tray and baffle-plate hereafter
described. Fig. 2 is a detached view of the wagon and Fig. 3. is a vertical section
of the disinfecting house.
On Sheet 2. Fig. 4. is a sectional plan view of the entire disinfecting house.
A being the compartment for the infected articles, B the container, and C, the
compartment for the reception of the disinfected articles.
In the first place my improvements relate to an improved construction of the
evaporating tray (marked m, m on the drawings of the Specification of the Patent
above referred to) the edges of which I now bend inwards at an angle as shown
at a, a in Figs. 1. and 3 instead of bending them over in a curved form, which I find.
to be more efficacious in preventing the water from boiling over.
Secondly I place above the evaporating tray a baffle plate b, b composed of cast.
iron or other suitable metal, covered with asbestos or other suitable non-conducting
substance, for the purpose of preventing the direct vertical evaporation and
radiation of heat and vapors and giving a sideways direction to the steam
evaporated by the boiling tray, so as to direct it towards a point immediately
above the open ends of the cellular bars which superheats the steam to a higher
temperature and the asbestos prevents the scorching or burning of the fabric or
article being disinfected.
Thirdly I arrange a supply cistern c, c in connection with the apparatus which
I provide with any suitable construction of ball-tap so as to automatically to
maintain the water in the evaporating trays always at the desired level so that it is
self-regulating.
Fourthly I propose to use in connection with this apparatus a conveyance (see
Fig. 2.) consisting of an inner and an outer chamber; the former being a case or
receptacle d, d for the infected articles and the latter a conveyance e, e fitted with
wheels for locomotion.
The conveyance e, e is open at one of its sides or ends only (preferably at the
back as shown) for the admission of the inner case or receptacle d, d, which slides

page_text: in a telescopic fashion in the outer chamber or conveyance e, e being fitted with
small friction rollers for that purpose (not shown on the drawing).
The inner chamber or case a, d is closed at that end or side which is left open in
the outer chamber or shell e, e, also at the top and bottom being open or having
openings either at one side or at both sides, so that when it is filled with the
articles to be disinfected and pushed into the outer shell or conveyance e, e it forms
its own door and effectually closes the same.
The inner chamber may be fitted with removable carrying bars which may be
employed also as shafts for moving the conveyance from place to place.
It must be understood that upon the arrival of this collecting carriage at the
disinfecting house it can either be enclosed bodily in the disinfecting apparatus and
disinfected, or the inner chamber or case with its open side or sides can be removed
from the outer shell or conveyance and disinfected with its contents; or the
contents of the inner chamber can be removed and placed upon the wagon f, f
which forms part of the apparatus as shown at Fig. 3.
A further modification of this wagon consists in having an enclosed box d¹ (see
Fig. 4) with simple double doors and running upon four wheels, for the purpose of
inserting, the same under and into the container B of the disinfecting apparatus,
but when it is being used for collecting the infected articles it is wheeled out, onto
à trolly g, g also having four wheels g¹, gl as shown and provided with folding rails
corresponding with the rails in the disinfecting house. It may then be conveyed
along the high roads upon this trolly. I prefer to make the bottom of the
chamber d', d with longitudinal openings closed with a sliding valve which is
opened when it is placed in the container B for disinfection.
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
First, in disinfecting apparatus of the class hereinbefore mentioned, the novel
construction of the evaporating tray with its edges bent inwards at an angle as
described.
Secondly, the combination with such evaporating tray of a baffle plate covered
with asbestos or suitable non-conducting substance for preventing the direct vertical
evaporation or radiation, superheating the steam and preventing the burning of
the articles.
Thirdly the combination with the evaporating trays of a supply cistern provided
with a ball tap for maintaining the water in the said trays always at the desired
level.
Fourthly the construction of the collecting conveyance with an outer case or
receptacle and an inner chamber enclosed as before described, either mounted upon
wheels or carried upon a trolly, and utilized as previously described.
