IMPROVEMENTS IN VENTILATING APPLIANCES Air Supplying Bracket
Year: 1884

page_text: I, JOHN MARSON LAMB, of 119 Finchley Road, South Hampstead in the County
of Middlesex, Engineer, do hereby declare the nature of my said invention for
IMPROVEMENTS IN VENTILATING APPLIANCES to be as follows:-
This Invention consists in the construction of Ventilating Air Supplying Brackets,
Slides, Tubes, Pillars &c. by which means the fresh air can be admitted into the
building either in an beated state, or cooled, filtered or unfiltered as may be desired,
I construct the same so that the cold air filtering and the heating chambers are
fitted in the portion that is embeded in the wall, and the diffuseing portion pro-
jecting on the inside of the wall, except when used as pillars or colums. They
can be constructed of any shape or configueration to suit any requirements, but the
most convenient is circular. and for the purpose of explanation. I herewith describe
one as two half cylinders fitted together to form one cylinder say for example
Gin long and 7 diameter, The bottom half cylinder, I fit up with three horizontal
tubes about 5in long, starting from the end that abuts the outside wall for the
admission of the cold air In these tubes, I place round brushes (sinilar to bottle
brushes) for a cleansing medium. The air having to pass through these tubes
becomes cleansed of all blacks and soots by friction with the bristles, fibres or
grasses of which these brushes are made, They can be withdrawn for washing, or
they can be left out when a large volume of air is required unfiltered, The top
half or heating chamber. I construct with a double or hollow back of about
to 1 space The inner plate of this back has five or more holes arranged round
the half circle to receive one end of the tubes which are about 51 long The other
end of these tubes pass through a seperate plate with corresponding holes which is
secured in its place by means of stay rods and nuts. to the end of the said tubes,
In the bottom portion of this front plate. I leave a long open slot, and make a
corresponding plate to fit it with a slide piece to open when it is required to light
the burner, I also fix a gas or other burner under these tubes for heating the said
tubes which is regulated by a suitable tap, The bottom plate of the heating
chamber has an hollow raised centre connecting with the hollow back, and
extending downwards to form a box which passes through the top plate of the
bottom half cylinder and fitting between the two cold air tubes and on the top of
the third, The front end of this box which is left open extends only as far as the
exit ends of the cold air tubes, I also make a coyer with a deep rim to fit the
front of the bottom half cylinder containing a loose valve plate. which is worked

page_text: by a screw in the front of the cover. This cover and valve regulate and direct the
incomeing current of air after leaving the three tubes into the receiving box, it then
passes through the hollow portion of the bottom into the back and then through
the several heated tubes arranged over the burner's, I also make a complete metal
cylinder to fit over the filtering and heating chambers and extending over their
front about 2 in this size which will bring it flush with the faceing of the wall,
and on the top part of this cylinder over the hot air tubes, I make a series of holes
which I cover over with a hood and pipe to convey away the products of combus-
tion, When making it as a ventilating bracket. I make my front projecting piece
to fit inside the encaseing cylinder and joint it either at the top, bottom, or side as
required, so that the gas tap and regulating valve is entireley hid from view and in
the inside of this front. I fix two or more seperating blades the entire width of the
front, to direct the air to the bottom and diffuse it equally in the room, It will be
seen that the action is as follows The outside cold air enters through the three
tubes contained in the bottom chamber and after passing through, not being able
to escape (on account of the cover and valve) it enters the receiving box, passes
through the hollow portion of the bottom into the back and thence through the
heated tubes, The warm air then descends to the openings of the front and passes
through the diffuseing plates into the room, I also make several holes in the most
convenient part according to the size and construction to feed the burner with
external air In constructing these ventilating appliances I do not bind myself to
round tubes, they can be made of any convenient shape, or of one hollow passage
for the cold air and one for the hot air, but I prefer to make them with tubes as
described. I thereby get a better heating surface and an easy escape of the
products of combustion, When useing these appliances in conjunction with a
vertical tube the bottom portion of the tube can be made in a seperate piece to
open for regulating and lighting, or I can make it without the bottom part and
thereby leave the gas tap and valve screw exposed, I also make a seperate loose
plate to close up the cold air tubes only and leave the receiving box uncovered so
that by keeping the burner alight. the temperature of the room can be raised
without the admission of any additional external air, When the air is required to
be cooled for lowering the temperature of the room, 1 remove the valve box cover
and substitute a deep box containing ice or other cooling medium, The air passing
over or through this cold chamber becomes cooled before entering the room, In
constructing large sizes for schools, or churches &c. I do not bind myself to any size
or proportion for they can be made to project into the building according to the
requirements, When making them in the pillar or colum shape. the fresh air
would be conveyed from the external wall by means of a connecting air chamber.

I, JOHN MARSON. LAMB of 119 Finchley Road, South Hampstead in the County
of Middlesex Engineer, do hereby declare the nature of my said invention for
IMPROVEMENTS IN VENTILATING APPLIANCES 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 in the construction of Ventilating Air Supplying
Brackets, Slides, Tubes, Pillars, &c by which means the fresh air can be admitted
into the building either in an heated state or cooled filtered or unfiltered as may
be desired. I construct the same so that the cold air filtering and the heating
chambers are fitted in the portion that is embedded in the wall and the diffusing
portion projecting on the inside of the wall except when used as pillars or column's
They can be constructed of any shape or configuration to suit any requirements
When making them in the cylinder form I construct them in two half cylinders
the bottom half I fit up with horizontal tubes for the admission of the cold air
when the air is required to be filtered I insert brushes as the cleansing medium
which can be easily with drawn for cleaning The top half or heating chamber
I construct with a double or hollow back. The inner plate of this back has holes
arranged round it to receive one end of the heating tubes. The other end of these
tubes pass through a seperate plate with corresponding holes which is held in its
place by means of stay rods & nuts. In the bottom portion of this front plate
I fit a seperate plate containing a slide to open for lighting the burner which
I place under the tubes regulated by a suitable tap. The bottom plate of the
heating chamber I construct to form a box in the centre for the conveyance of the
cold air to the distributing chamber or hollow back as in Fig 1 or I can make it at
the end of the bottom plate as in Fig. 2 with regulating valve, I also make a
cover with a deep rim to fit the cold air portion containing a loose valve plate
which is worked by a screw in the front of the cover this cover & valve regulate
and direct the incoming current of air into the several heated tubes arranged over
the burner. I then make a complete metal casing to fit over both the filtering
& heating chambers which practically unites the two valves into one and on the
top of this metal caseing I construct a flue pipe for carrying away the products of
combustion When making it in the bracket form I make my front to fit inside
and joint it either at top bottom or side as required so that the gas tap and valve
is entirely hid from view, It will be seen that the action is as follows The outside
cold air enters through the filter tubes contained in the bottom chamber and after
passing through not being able to escape (on account of the cover & valve) it enters
the receiving box then passes through the aperature in the bottom plate and
through the heating chamber into the room, I supply the burner with air from the
external wall through the hollow back of heating chamber through seperate
channell's, In constructing these ventilating appliances I do not bind myself to
round tubes for they can be made of any convenient shape or of one hollow
passage for the cold air and one for the heated air but I prefer to make them with
tubes as described I thereby get a better heating surface and a more easy escape

page_text: for the products of combustion, When using these appliances in conjunction with
a vertical tube the bottom portion of the tube can be made in a seperate piece to
open for regulating and lighting or I can make it without the bottom part and
thereby leave the gas tap and valve screws exposed as in Fig. 2
When bracket,
Fig. 1, is used for stoveing the room I make a seperate loose plate to close up the
cold air tubes only, and when used for cooling & disnifecting purposes I fit a loose
box containing ice or disnifectants in the place of the regulating valve. In con-
structing larger sizes, I do not bind myself to any given proportion for they can be
made to project into the building according to requirements When making them
in the pillar or column shape the fresh air would be conveyed from the external
wall by means of a connecting air chamber.
The accompanying drawing will serve to more fully explain my said invention
The various parts can be made of metal or metal and earthenware combined or any
other suitable material.
