I, ROBERT MEIN, of Southwold Road Wrentham, in the County of Suffolk,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the supporting of fire grates of stoves and ranges
in such a manner as to enable them to be tilted for the removal of cinders and
ash.
The improvements consist in the two bottom side bars and the front bars being
made in one piece. The bottom side bars are provided with pins or trunions at
or near their centre. The other bottom bars which are made in one piece have
the outside bar on each side provided with lugs or brackets open at the bottom
and which fit over the said pins or trunions so that the bottom bars may be
tilted in such a manner that while the front portion is lowered the back portion
is raised. The said lugs or brackets may each be provided with two bearings
for the reception of the pins or trunions one at the top and the other in the side.
The one at the top being used when the bottom bars are in position for fire and
the one in the side coming into use when the bars are tilted. The position of the
latter bearing is such that the bars cannot fall off the pins or trunions when
the bars are tilted.
When the bottom bars are in position for fire they are automatically secured
by means of a drop pin or catch. When a drop pin is used it is so arranged
as to pass through a hole in the bottom rail of front bars.

Improvements in Grates for Cooking Ranges and Stoves.
I, ROBERT MEIN, of Southwold Road Wrentham, in the-County of Suffolk,
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 the supporting of fire grates or grids of stoves and ranges
in such a manner as to enable them to be tilted for the removal of cinders and
ashes. And in order that my invention may be fully understood and readily
carried into effect I shall now proceed to describe the same with reference to the
accompanying drawings.
Fig. 1 is a front elevation of a range constructed according to my invention,

page_text: Fig. 2 is a sectional side elevation shewing my tilting grate in the tilted or raised
position for discharging the cinders and ashes, Fig. 3 a sectional side elevation
shewing the grate or grid in the ncirmal position and Fig. 4 a plan of the said
grid. The front bars A at each side are continued downward and then carried
to the back as shewn at A' while the lower middle portion of the grid or grate 5
proper is cut away. B B are pivots or gudgeons by preference cast on at or near
the centre of the bottom side bars A'. The bottom or centre art C of the grate
or grid shewn at Figs. 3 and 4 is made in one piece separate from the front bars
and is on each side provided with lugs or brackets C open at the bottom and
which fit over the said pivots or trunnions B so that the bottom part or grid C
may be tilted in the manner shown at Fig. 2 that is with the front portion
lowered and the back portion raised. These lugs or brackets C¹ are by preference
formed with two bearings C and C³ the former at the top and the latter at the
side; or if I use one bearing I continue the back lug downward to such a distance
that the grid C cannot slide off the pivot B even when tilted to an angle of 90°.
The bearing C is used when the gril C is in position for fire and the bearing C³
comes into use when the grid C is tilted. The position of the bearing C³ is such
that the grid C cannot fall off the pivots or trunnions B even when tilting to an
angle of 90°. When the grid C is in position for fire it is automatically secured
by means of a drop pin or catch D shown also separately in the side view Fig. 5
and plan Fig. 6; when a drop pin is used it is so arranged, as shown, as to pass
through a hole formed in the front bottom rail of the front bars A. The centre
of the trunnions B is some distance from the top (and also by preference a
little towards the front of the bars, whereby I obtain a secure locking action by
the catch D.
When the grid C is tilted back again the projection C on the inside of the
front rail comes against the drop pin, or catch D and raises it, the projecting
peg D entering the notch A³ until the grid C has assumed the horizontal position
when the drop pin D comes opposite the notch C' and drops down through it and
in that position serves to hold the grid C in the normal position when in use.
Fig. 7 is front elevation Figs. 8 and 9 sectional side elevations and Fig. 10 a
plan view of a grid C made with deeper lugs C than in the previously described
figures for the purpose of raising the grid and thus allowing the use of a shallower
depth of fire. For this purpose it is also provided with feet Co at or near the
back for supporting the grid on the back rail A³ The deep-bearing lugs C¹ have
bearings (and ( The bearings (take on the pivots B when in the normal
position and as the grid is tilted the bearing lugs Cf ride upon the pivots B until
the latter enter the bearings ("the inner side. As of the lower bar or rail of the
front bars forming an abutment or fulcrum against which the edge C³ of the grid C
takes its bearing at the beginning of the tilting operation. In order to take
hold of the grid C for the purpose of tilting it I form it in front with two eyes or
eye lugs C into which I insert two prongs made with a handle. In order to
prevent the cinders and ashes from dropping off at the sides and at the back
and thereby clog the spaces at the sides and back of the tilting grid C, I provide
raised side walls C and back wall C all sloping on their inner sides. Further-
more to guide the tilting grid C during the tilting operation I provide it with
a front ledge C7 the end faces of which work between the down continuations A¹
of the front bars. This ledge normally rests against the bottom trail of the front
bar; it is hollowed out underneath in front in order to clear the bosses B¹ of
the pivots Bas shown in Fig. 9
Some of the advantages of this invention are firstly that the present dirty
and slow work of clearing out the cinders and ashes partly by raking out but
mostly by picking out the cinders by hand is superseded by a quick and cleanly
operation thus also economizing time when lighting the fire secondly that when
the bottom part of an ordinary grate has been burnt out an entire new grate
has to be supplied but in a grate fitted with my tilting grid only that latter
prært has to be renewed while the rest of the grate remains useful for a long time.

page_text: Thirdly by the optional use either of a shallow tilting grid (Figs. to 6) or
a deep tilting grid (Figs. 7 to 10) facility is given for making either a deep or a
shallow fire. Fourthly this tilting grid is easily applied to existing cooking stoves
and ranges inasmuch as the ordinary grate or grid part with front bars has to be
removed and my tilting grid and front bars put in instead these front bars will
then outlast two or more tilting grids which latter are easily replaced when
burnt out.
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. A tilting grid provided underneath with lugs having two bearings for
gudgeons provided on the side bars of the front substantially as described with
reference to Figs. 1 to 4.
2. A tilting grid provided underneath with lugs having two bearings for
gudgeons provided on the side bars of the front and provided with sloping side
walls and back wall, substantially as described with reference to Figs 7 to 10.
3. The drop pin or catch D on the front in combination with the notch C" on
the tilting grid.
4. The construction of the bars A, having the part between the side pieces A'
and A¹ cut away to make room for a separate tilting grid, said pieces being
provided with pivots B, substantially as described and shewn.
