PROVISIONAL SPECIFICATION.
Improvements in Apparatus for use in Warming and Ventilating
Apartments and other Places.
We SAMUEL REEVE and CHARLES EDWARD RATCLIFFE trading as Reeve & Ratcliffe
at 10 Berners Street, in the County of Middlesex, Engineers do hereby declare the
nature of this invention to be as follows:-
These improvements have reference to modifications in the arrangement of parts of
apparatus for warming and ventilating apartments and other places of the character
described in the specification of Letters Patent granted to Samuel Reeve, one of the
present applicants, and dated 17th June 1887 No. 8738.
According to the present improvements the filter box may be constituted as described
in the said patent specification or be formed with any suitable refractory reticulate
material adapted to intercept the denser matters.
We find however superposed sheets or layers of wire gauze or assemblages of wires
to form a filtering pad or check to answer well.
In some cases in place of the wire filter or check a check or baffling arrangement
of plates of metal or refractory material, assembled in more or less close order, may
be employed; and these plates may be adjustable and removable according to require-
ments, and the whole may slide on guide-ways to and from the front.
The sides and other portions of the fire basket are formed so as to avoid angles in
which fuel can lodge so as to impede combustion and. lodgement of ash.
Side and other flues may be used if desired..
In front of the space immediately over the filter box is swung a plate or hood which
may be bright.or ornamented or interchangeable plates may be used say a bright heat
reflecting plate for winter and an ornamental substitute for summer; behind and some-
what above this front swing plate is a jointed double register plate or valve which
may be adjusted in various positions to regulate passage of products of combustion
and gases.
The front. swing plate or hood.. may swing forward of the front of the filter or
baffle, box or may be angularly, pushed back as adjustment of draught requires, or
such plate may
be capable of adjustment by being raised and lowered, the edges
being guided by grooves at the sides of the stove and to economise vertical space
the plate may be in divisions so that the parts stow-away in their casing one behind
the other..
Weighted counter balance levers are. employed to enable the vertically rising part
or parts to be raised' lowered or remain suspended in intermediate positions.
A form of such counterweight levers consists of an axial pin fixed to the back
plate rearward of the sliding plate, on which pin are centred two cross. arms each
double the one pair of opposite ends bearing counterweights and the other or inner
pair being curved and longitudinally slotted to receive fixed pins projecting from the
movable vertical plate.

page_text: In Figs. 3 and 4 the sliding plate 6 is shewn arranged vertically so as to slide up
and down within the curtain c, and its position is regulated by means of the balance
weights g, g, suspended on the cranked arms 9', gl, centred at on a stud projecting
from the fixed part of the stove, and having inclined grooves 9,0³, at their other ends,
which embrace studs 9, 9', projecting from the sliding plate b.
These weighted counter-balance levers g¹, g¹ are employed to enable the vertically
rising part or parts 6 to be raised, lowered or remain suspended in intermediate
positions. A form of such counterweight levers consists of an axial pin g³, fixed to the
back-plate rearward of the sliding plate b, on which pin are centred two cross
arms g', gl each double, the one pair of opposite ends bearing counterweights g, g and
the other or inner pair being curved and longitudinally slotted at 93, 9³ to receive
fixed pins g* projecting from the movable vertical plate b.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In apparatus for use in warming and ventilating apartments and other places,
the combination with a stove or fire place, of a filtering medium, or baffle plate, as a,
a swing plate as b, regulating valve d, and flue for escape of products of combustion as
set forth in respect of Figs. 1 and 2.
2. In apparatus for use in warming and ventilating apartments and other
places, the combination with a stove or fire place, of a filtering medium, or baffle
plate, as a, a sliding vertical plate as b weighted counter-balance lever arrange-
ments for supporting and controlling the movement thereof, regulating valve d,
and flue for escape of products of combustion as set forth in respect of Figs. 3
and 4.
