PROVISIONAL SPECIFICATION
An Improved Drop Frame and Coal Economiser for Attachment to
Kitchen Grates.
SAMUEL SKERRITT, 63, Randall Street, Sheffield, Ironworker, I do hereby declare
the nature of this invention to be as follows:-
1
The above is made with a outside frame & inside frame. The outside frame is
made hook shape to drop on the bottom bar of a kitchen grate. These hooks
are about 5in. deep & bent square to project about 3in. At the end of the pro-
jections is rivetted a round cross bar & the same at the top of the hooks. The
sides of the inside frame is bent square to correspond with the outside frame.
There is two cross bars in the inner frame 'flat ones, I then place across the two
horizontal bars six or eight upright bars flat, these are rivetted together with
rivets. The inner frame works on the bottom cross bar of outer frame. Being
cranked its own weight causes it to close when passing the centre.
Dated this 26th day of February 1898.

An Improved Drop Frame and Coal Economiser for Attachment to
Kitchen Grates.
I, SAMUEL SKERRITT, 63, Randall Street, Sheffield, Ironworker, do hereby declare
the nature of this invention and in what manner the same has to be performed,
to be particularly described and ascertained in and by the following statement: -
My invention relates to an improved coal economiser and drop-down bar or
support for tins, saucepans and the like, which retains its closed position by
gravity, without the aid of catches or other fastenings.
It is shown in the accompanying drawings, similar figures of reference indicate
similar parts in either of the views.
Fig. 1 shows the apparatus with the bar or supporting shelf let down, and its
position when raised is indicated by dotted lines.
Fig. 2 is a plan of Fig. 1.
The apparatus consists of two chief parts, the outside or hook frame 1, and the
inside frame or supporting shelf 2, the junction of the two being at 3, which is the
pivot upon which the part 2, turns.
•
The part 1, consists of two hooks 4, with their lower ends 5, returned at a right
angle, and having a small inside lug 6, to form a bearing which stops and supports
the part 2, when it is in a horizontal position; the two hooks are held firmly in

page_text: their respective places by two stay rods 7 and 8, and are made short so as to
engage with the lower fire bar of a kitchen grate.
The inside frame 2, also forms the economiser when it is turned up against the
firebars as it prevents the escape of pieces of coal between the ordinary fire bars,
and when turned down it forms a shelf to support anything which may be placed
upon it.
The side bars 9 are bent at the ends where they are connected with the hook
frame, and are provided with holes through which the round rod 8, is passed, and
upon which the said shelf turns; stay rods 10 and 11 connect the two sides of the
frame rigidly, and a number of flat bars 12 are secured upon them to form the
shelf or grid.
When the inside frame or shelf is turned up to a horizontal position or nearly so,
its weight is beyond the centre 3, upon which it turns, and consequently it falls
to its position against the stay rod 7, by force of gravity.
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
The improved apparatus constituting a coal economiser and a dropbar or shelf,
constructed as hereinbefore described and shown in the drawings.
