COMPLETE SPECIFICATION.
Improvements in Apparatus for Feeding Fires from the Bottom.
ANDREW RENFREW of 68 Lumsden Street in the City of Glasgow in
Lanarkshire Engineer do hereby. declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
My invention consists of a box with a plate or grating attached to the top at
right angles to the sides flush with top of box at the back a sliding grating or bottom
raised and lowered inside box by a lever, grating to form bottom of fire-place when
raised with slide bars on ends of box to slide under fire-place like a drawer Fig. 10.
In another form which I prefer the top of box, bottom, and plate is circular and
the ends of box extended to form centres of or apparatus to work on as in Fig. 1
which shews a common kitchen fire-place with end view of apparatus under fire-
place and lever for raising bottom.
Fig. 2 shews end of apparatus removed with bottom raised.
Fig. 3 shews apparatus drawn out with bottom lowered ready for new charge
of coal.
Fig. 4 shews apparatus with side removed pushed under fire-place with new
charge ready for being raised by lever into fire-place.
Fig. 5 shews front view of fire-place with apparatus in position the front side
being removed and shewing bottom raised.
Fig. 6 shews apparatus detached.
The feeding of the fire is accomplished as follows.
The apparatus is pulled out and the plate at the back comes under the
fire and holds up live coal, the bottom is lowered as shewn in Fig. 3 and the box
filled with coal, it is then pushed under the fire as shewn in Fig. 4 and the bottom
with the fresh coal is raised by the lever as shewn in Fig. 2. This apparatus is
not confined to any particular fire-place.
Fig. 8 shews end view of Fig. 7 in position under fire grate with lever for
raising and lowering bottom and slides on ends.
Fig. 9 shews front view of Fig. 7 with bottom raised.

page_text: Fig. 10 shews apparatus drawn out with bottom lowered ready for new supply of
coal.
The working of Figs. 6 & 7 are alike except that Fig. 7 slides out while
Fig. 6 turns out on a pivot.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. A box sliding or working on a pivot under fire-place.
2nd. A plate or grating attached to the back of box either flat or circular to
hold up hot coal while the box is drawn out and
3rd. A sliding grating or bottom raising or lowering by a lever in said box.
Dated this 27th day of May 1891.
