PROVISIONAL SPECIFICATION.
Adjustable Grates for Kitchen Ranges.
EDWARD GALLOWAY REEVE 36 & 38 Duke Street, Norwich, Ironfounder
and Range Maker, does hereby declare the nature of this invention to be as
follows
The grate is fixed to a rack and pinion which is worked by means of a loose
spindle. The front of spindle has teeth arranged round it, which fit into corre-
sponding grooves in front of barframe. By pushing the spindle into the grooves it
becomes immoveable and by pulling out the spindle just far enough to liberate the
teeth from the grooves, it can be turned either way, moving the grate up or down
as desired.
The rack and pinion are held in position by means of a surrounding frame,
which is fixed to the back of barframe. The spindle is drawn out, turned round
and pushed in by means of a loose key with a solid bit at the end.
In the front end of spindle there is a grooved aperture for the insertion of the
key, the end of the aperture being enlarged so as to allow the bit of the key to
turn a quarter circle either to the left or to the right: the bit of the key thus
turned, catches the ledge inside the aperture and the spindle may be pulled out
sufficiently far to free the teeth from the grooves in the front of barframe and can
be turned either way moving the grate up or down.
The accompanying drawings shew the various parts of the invention:
On Sheet 1, is a front elevation of the barframe shewing the following
Meeth of spinare.
On Sheet 2 is a section on A B (see Sheet 1.) which illustrates the spindle S
drawn out and free to turn the grate up or down.
The reference letters on Sheet 1 refer to the same parts in the section on
Sheet 2.
Lis one of the grooves in the front of barframe,
N, the pinion,
O, the enlargement of the grooved aperture, shewing ledge whereon the bit of
the key catches,
R, part of the frame which supports rack and pinion.
The section on CD shews the square part of spindle which passes into the
pinion.
Section on E. F. shews the pin passing through end of spindle to prevent it from
being drawn entirely out.
On Sheet 3. is plan and elevation of the key shewing solid bit at Z.
The plan of the key shews the shape of the bit to be same as that of the grooved
aperture in front end of spindle (K on Sheet 1) into which it passes.

page_text: R-part of the frame which supports the rack and pinion,
-the enlarged portion of the grooved aperture shewing ledge whereon the bit
of the key catches;
Section on C D shews the square part of spindle which passes through the
pinion;
Section on E F shews the pin passing through the back end of spindle to prevent
it being entirely drawn out;
On Sheet 3 is a plan and elevation of the key shewing solid bit Z.
The plan of the key shews the shape of the bit to be the same as that of the
grooved aperture in the front end of the spindle (K on Sheet 1.) into which
it fits.
Assuming the grate to be in a steadfast position and that it is desired to raise it,
first insert the bit of the key into the grooved aperture in spindle as far as it will
go, slightly turn the key to the right so that the bit catches the ledge inside the
aperture, then pull and the spindle comes towards you sufficiently far to free its
teeth from the grooves in the front of barframe, turn the spindle until the grate

page_text: reaches the desired height, then push the spindle back fitting its teeth into the
grooves in the front of barframe and the grate remains steadfast.
The grate is lowered in precisely the same manner except that the spindle is
turned to the left instead of to the right.
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
1. The construction of the spindle and its arrangement with the barframe, by
means of which the spindle is prevented from turning to the right or left, the teeth
of the spindle fitting into the corresponding grooves in the front of the barframe.
2. The construction of the key and its relation to the spindle; by means of it
the spindle can be pulled forward, turned and pushed backwards.
3. The arrangement of the grate rack and pinion with the spindle and barframe
by which the complete process of moving the grate to a desired position is
performed.
