TRUVIDIONAL DE MOIETUATION.
Improved Ventilating Apparatus for Drawing Off Foul Air from
Rooms, Lamps, Gasaliers, and the like.
ALFRED PLATT of Stockport Road Gee Cross Hyde Cheshire Plumber and
Glazier &c. do hereby declare the nature of this invention to be as follows:-
The principal object of this invention is to take off all noxious fumes &c. produced
by gas lights or lights from oil lamp &c. and also to ventilate rooms &c. whether
the lights is on or not and to keep ceiling clean also to reflect.
The ventilator is made from slieet iron, tin, brass, &c. in the form of a circle in
three parts namely top, center, and bottom and held together by three set screws.
The outside and center part is stationary. The part between the outside and the
center is a loose flat peice made of same material which works on three wheels and
the wheel bearings are fastend to the bottom part. The top part is full of holes
at the sides. These holes are directed upwards by a cavity inside the ventilator.
The bottom part has a number of holes one inch apart. The center part is a
bearing for gasfittings, oil lamps &c.
In the center their is a hole right through for lockantting up to the ceiling the
whole of the ventilator and the gasfitting or a holder for lamps &c. at the same
time.
The fumes and heat from the ventilator is carried away by a pipe made of iron
off the topside of ventilator as near to the edge as possable, through the ceiling
underside floor to the outside of building.
From the loose part of ventilator a brass pipe is suspended in accordance with
the height of the rooms. This pipe goes up inside the ventilator 14" and locknutted
to the loose part, a smaller size of pipe, this to slide up the pipe that goes to the
ventilator. This smaller pipe is fitted to a tee peice and from this tee, a pipe in
the shape of a swan nack bend or a straight pipe to match the gaslights or
lamps &c. At the end of this swan neck bend &c. is a holder or gallery for shades.
The cross part of the tee is a bar about 3" long which goes across to the down
pipe of gasfittings and held fast by a clip and set screw.
The shades can be made in various shapes to seut the rooms and fitting and made
of glass or enamel iron. The shade when fixed is right over the light of the gas or
lamps to receive the fumes and heat from the gas or lamp lights and the like.
From the shade the fumes &c. goes through the shade and up the pipes into the
ventilator out of ventilator under the floor to the outside of building &c.
The shade, pipes and loose part of ventilator will turn round slide up and down
with the gasfitting as required and still be in the same position over the light.
