Improvements in Ventilating Valves or Wall Ventilators.
1, EZRA HATTON 110 Sackville Street Manchester Engineer do hereby declare
the nature of this invention to be as follows:-
The object of my invention is to produce a ventilator for either ingress or egress
of air, with a self sustaining valve which may be opened, closed, or regulated,
without the aid of racks, cord, or other visible means of adjusting, or controlling
the area of the opening of the ventilator, and to which a corrugated gauze cover
can be fixed for intercepting smuts & dirt and avoiding draughts.
My invention is carried into effect as follows.
A. cast metal frame or box is formed with a channel or groove inside each of the
two upper corners, and in which a spring is inserted, the front of ventilator which
forms the valve is hinged at the bottom and opens outwardly with quadrant sides
attached, the top portion of these sides works inside the above mentioned channels
or grooves and is kept in contact with the springs, so as to sustain the valve in
any position, the front of box is grooved to form air tight hinge & joint, the gauze
cover is fitted to upper part of the valve.

COMPLETE SPECIFICATION.
Improvements in Ventilating Valves or Wall Ventilators.
I EZRA HATTON Engineer 110 Sackville Street, Manchester, 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 :-
The object of my invention is to produce a ventilator either for ingress or egress
of air with a self sustaining valve, which may be opened, closed, or regulated,
without the aid of racks, cord, or other visible means of adjusting or controlling the
area of the opening of the ventilator, also to ensure noiseless working, a weather
tight hinge or joint, and to which a corrugated gauze cover can be attached for
intercepting smuts and dirt and avoiding draughts.
Fig. 1. is a section of a portion of a cast metal frame, A is the frame, B is a
channel or groove cast in front of same, C is the valve with beaded edges formed
so as to fit into the groove B.
Fig. 2. is also a section shewing the top and bottom of the cast metal frame, D is
a feather spring securely fixed inside a channel which is cast inside each of the two
upper corners of the frame A', E is a brass bead fixed on the top of each of the
two quadrant sides of the valve and kept in contact with the springs, F is the
hinge or pivot on which the valve works.
Fig. 1.
B and C correspond to B & C on
Fig. 3. is a sketch of the cast metal frame complete, at G in each of the two
front upper corners of the frame a half round hole is cast, through which the brass
bead E moves to & fro when opening or closing the valve.
Fig. 4. is a sketch of the valve with quadrant sides and method of fixing the
springs for sustaining the valve in any position, also shewing the groove or channel
at D in which the springs are securely fixed, F shews the projecting wire rod at
bottom of valve front, the ends of this rod are passed through holes, drilled in the
cast iron frame to form the hinge or pivot.
Fig. 5. is a complete sketch of the frame and valve, A³ is the cast frame, B³ is
[Price 6d.]

page_text: the channel or groove, C³ is the front of valve, D2 is the position of spring and
channel for same, 2 the side quadrant with brass bead at top, F3 is the pivot or
hinge, G¹ is the half round hole in front, H the corrugated wire gauze screen or
cover.
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. The method of sustaining a valve in any position by means of feather
springs secured in a groove or channel which is cast inside the two corners of the
metal frame, & which holds the springs in close contact with the top of the quadrant
sides of valve.
Second. The fixing of a brass bead on the top of the quadrant sides of valve
to ensure noiseless friction, smooth working, rustless contact, and the making of a
weather tight hinge or joint by means of a groove or channel formed at the front
of the ventilator and into which fits the beaded edges of the valve, and the wire
rod forming the pivot.
Third. The fixing of a corrugated wire gauze screen or cover for intercepting
smuts and dirt, and avoiding draughts.
