PROVISIONAL DIBUITIVATIO
Improvements in Fire Grate Frets.
We, Messrs. HARDY & PADMORE LIMITED of the Worcester Foundry in the
City of Worcester, Iron Founders, and JOSEPH SOUTHALL Manager of the
aforesaid Foundry, do hereby declare the nature of this invention to be as
follows:-
the space,
Our invention consists in making the article commonly used to close up
between the bottom of the front bar of a fire grate and the hearth and generally
termed the fret of a fire grate in such a manner that it can be fixed at various
heights from the hearth; for this purpose the fret may either work in grooves
having projections on its back to hold it up, or it may be provided with hooks so as
to hang in the desired positions, or again if the bars and fret are flat, the fret
may be hinged at the top so as to turn upwards and fix at any desired angle, in this
case if fastened in a horizontal position it will serve as a plate rest. If the fret
rests on the hearth the combustion will be slow, if slightly raised, air will be
admitted to the bottom bar, if it is raised so as to close up the front bars it serves
to rapidly draw up the fire, this last position being convenient for gathering up
the ashes as the fret does not have to be removed, as is the case with ordinary frets.

Improvements in Fire Grate Frets.
We, Messrs, HARDY & PADMORE LIMITED of the Worcester Foundry in the
City of Worcester, Iron Founders and JOSEPH SOUTHALL, Manager of the
aforesaid Foundry 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 nature of our invention is made clear by the accompanying drawing and
consists in making the fret A-see Figures 1 and 2,-in such a manner that it can
be fixed at various heights from the hearth, for this purpose the fret may either
work in grooves B, see Figure 3,-having projections on its back to hold it up, or
it may be provided with hooks so as to hang in the desired positions, or again if the
bars and fret are flat, the fret may be hinged at the top-see Figure 4,-so as to
turn upwards and fix at any desired angle, in this case if fastened in a horizontal
position it will serve as a plate rest. If the fret rests on the hearth, as in
Figure 1, the combustion will be slow, if slightly raised, air will be admitted to the
bottom bar, if it is raised so as to close up the front bars, as in Figure 2, it serves
to rapidly draw up the fire.
The projections to maintain the fret in its raised position-see Figure 2-are
cast inside near the bottom of the fret and the play in the grooves allows them
either to pass the horizontal bars, or when the fret is pressed inwards to rest on
such bars supporting the fret; if the fret works as shewn in Figure 4, a segmental
toothed rack R pivotted on the fret engages on a stud $ on the bar frame,
D

page_text: maintaining the fret in the desired position, to lower the fret the rack is depressed
at the front end lifting it off the stud.
The rack, has its teeth on the underside so that as the fret is lifted the teeth
which are retchet shaped are drawn over the stud engaging with it directly the fret
is loosed, or until that end of the rack in which the teeth are is lifted off the stud
by the depression of the front end of the rack at a point outside the pivot
in the fret.
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 :
Constructing the frets of fire grates according to the manner and for the
purpose described above.
