PROVISIONAL SPECIFICATION.
Improvements in Ventilating Grids or Gratings.
1, CHARLES KITE, of Baronsmere Road, East Finchley, London Sanitary
Engineer, do hereby declare the nature of this invention to be as follows:
According to this invention a rebate is formed in the frame of the grid or grating,
while the grid or grating itself forms a movable panel which can be lifted in and
out of such frame, so as to afford ready and convenient access to the shaft or flue
or other opening to which the grid or grating is fitted, for the purpose of clearing
out, cleansing or repairing such shaft, or flue, or other opening as occasion may
require. One or more lugs or their equivalents is or are cast or otherwise formed
on or fitted to the back of the frame, and each such lug or its equivalent has an
aperture formed therein to receive a pin, or screw, or other fastening, which
serves to secure and retain the grid or grating in position when fitted into the
frame.
My invention possesses the essential advantages of great simplicity and
utility, combined with economy of cost in manufacture and an ornamental
appearance.

Improvements in Ventilating Grids or Gratings.
I, CHARLES KITE of 31, Baronsmere Road, East Finchley Engineer, 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 :-
According to this invention the frame and panel of a ventilating grid or grating
are made separate from each other so as to form two distinct parts. A rebate or
groove is formed in the top and bottom of the frame while the grid or grating itself
forms a movable panel which can be lifted in and out of such frame so as to afford
ready and convenient access to the shaft or flue or other opening to which the grid
or grating is fitted for the purpose of clearing out, cleansing or repairing such shaft
or flue or other opening as occasion may require. One or more lugs or their
equivalents is or are cast or otherwise formed on or fitted to the back of the frame,
while one or more holes is or are made in the border of the grid pauel and tapped
to receive one or more pins, screws or studs which when inserted therein and
tightened up, take their bearing against such lug or lugs and so hold the panel in
position when fitted in the frame. Or the lug or lugs or their equivalents may
each have an aperture formed therein to receive a pin, stud, screw, or other
fastening to so retain the grid in position. If desired the movable panel
may be provided with a centre knob to facilitate lifting it in and out of the
frame.

DRAWINGS.
Figure 1 of the accompanying drawings shews a cross section taken on the
line A. B. Figure 2 of the frame of a ventilating grid or grating made according to
my invention and Figure 2 is a plan view of the frame and grid when fitted
together.
Similar letters indicate corresponding parts in both figures.
a', a² are the top and bottom rebates or grooves formed in the frame a the top
rebate or groove being made somewhat deeper than the bottom one to allow of the
movable panel b being readily lifted in and out of the frame. c is a lug cast or
otherwise formed on the top of the frame at the back. d is a pin, screw, stud, or
other similar fastening which is fitted in a hole d' in the border of the grid or
grating for the purpose of holding it in position as already described.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is ;-
1. As a new article of manufacture a ventilating grid or grating having a
movable panel that can be lifted in and out of the frame of such grid or grating all
substantially as herein before described.
2. Making the frame and panel of a ventilating grid or grating in two
distinct parts and forming a suitable rebate or groove in the top and bottom
of the frame and one or more lugs thereon all substantially as hereinbefore
described and shewn.
