COMPLETE SPECIFICATION.
Improvements in Ventilating Grates, Ranges, Stoves, and the like.
I MALCOLM THOMAS LANDER of 2 Ashbrook Road, Upper Holloway, N.
Hot Water 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:-
This invention relates to improvements in grates known as ventilating grates
or those to which cold fresh air is supplied, and from which warm fresh air is
given off.
The object of my said invention is to provide improved means whereby the
quantity and direction of the warmed fresh air may be more readily controlled and
to provide improved means for giving access to the air chamber for cleaning and
such like purposes.
For the better explanation of my invention I append the accompanying sheet of
drawings in which Fig. 1 represents the front elevation of a grate embodying my
improvements. Fig. 2 is a vertical section taken through such grate, and Fig. 3 is
a horizontal section or plan.
the rear.
A represents the air chamber which is at the back of and around the sides of the
grate. The air is supposed in this case to be brought in by means of a duct A' at
B is a moveable valve to control the amount of air admitted to the room,
and to give such incoming warmed air an upward direction, and to prevent its being
drawn directly into the fire place as is the case of air outlets now in common use,
and it allows the air to pass out freely without having more contact than is strictly
necessary with the ironwork.
The valve B is fitted with little clips or hooks at either end, C which are designed
to engage with the edges of the grate front, and hold the valve in any position
in which it may be placed according to the sweep indicated by the dotted line on
Fig. 2, without further support or fastening, such a result being readily obtained
by lifting the valve slightly and giving it a tilt forward the bottom striking the
nozzle at back, and so fixing it by its own weight to the required position.
The valve can be removed entirely if so desired for cleaning or other purposes
by moving it back into the air space and then drawing it forward cornerwise.
Immediately behind the valve B, l'arrange a moveable gauze wire screen D which
is held in position by any suitable simple means, such as a rebate formed on the
grate casting, lugs, or the like according to the shape of the grate. In order to
give convenient and ready access to the air chamber for cleaning and such like
purposes I make the portions of the grate E, E, entirely removeable. They may
be solid metal or metal frames carrying tiles, or any other known design or finish.
I attach them in position by screws or other suitable contrivance that can be easily
controlled. By this feature of my invention the air space at the sides and rear of
the grate can be easily got at for cleaning or other purposes. The sides are made
so as to allow of no escape of air when fixed. The nozzle on top of the grate
allows a good sound joint to be made, so as to keep the air and smoke totally
distinct and can be fixed by any ordinary workmen and in case of repairs it is a
simple matter to unfix and refix the stove. The shape of the fire brick back of
the stove is such that the air in coming in is warmed by first striking the bottom of
the back and afterwards striking the upper portion of the back before it is allowed
to pass out into the room through the valve as described.

page_text: 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
(1.) Improvements in ventilating grates, consisting in fitting a controllable valve
to the air chamber adınitting a regulated quantity of warm air to the room sub-
stantially as and for the purposes specified.
be
(2.) An improved valve for use with ventilating grates consisting of a hinged
flap fitted to the front of the air chamber provided with means by which it may
in any position substantially as described and shown and for the purposes specified.
(3) In ventilating grates a section of the fire lump or back brick of the fire
substantially as shown.
(4.) In ventilating grates the combination with the regulating valve 'above
claimed, of a screen fitted at the back of the said valve substantially as described
and shown and for the purposes specified.
(5.) In ventilating grates the use of removeable panels adapted to give access
to the air chamber for cleaning and other purposes substantially as set forth.
