Year: 1877

page_text: LETTERS PATENT to William Robert Maguire, of the Firm of Maguire and
Son, of Dawson Street, in the City of Dublin, Ireland, for the Invention of
"IMPROVEMENTS IN KITCHEN OR COOKING RANGES."
Sealed the 20th October 1877, and dated the 17th August 1877.
PROVISIONAL SPECIFICATION left by the said William Robert Maguire at
the Office of the Commissioners of Patents on the 17th August 1877.
. WILLIAM ROBERT MAGUIRE, of the Firm of Maguire and Son, of Dawson Street,
in the City of Dublin, Ireland. "IMPROVEMENTS IN KITCHEN OR COOKING
RANGES."
This Invention consists in improvements in the construction of kitchen or cooking
ranges, whereby the consumption of fuel is economized and the general efficiency of
the range increased. .
In carrying out my improvements, I employ a front grating consisting of a series
of bars, the two end or side bars of which are continued or extended upwards and
serve as handles and also as stops, as herein-after described. This grating forms
the lower part of the front of the fire-place when in its vertical or normal
position.
In cach of the said side bars is a slot, such slots catching or hanging on one
of the horizontal fire-bars of the range; the herein-before described grating is thus
pivotted on the said fire-bar; the upper fire-bar serves as a stop against which the
said side bars or handles rest when in a vertical position, and the upper bar is made
moveable so as to allow of the front grating being moved outwards when required
for cleaning away ashes or otherwise. By the employment of this swinging front
grate the depth of the fire may be varied; when the full depth is required the
front grating is vertical, but when the fire is to be reduced by pulling down the
handles by means of a rod provided for this purpose the front grating will turn on
the bar on which it pivots, and be brought into a horizontal position and form the
bottom bars or grating of the fire-place.
The front of the boiler forms the back of the fire-place, and the lower part thereof
is of a curved form, concentric with the bar on which the front grating revolves,
and this curved part forms the bottom of the fire-place when the front grating is

page_text: vertical. The boiler is provided with a cleaning or man-hole door in the boot, so
that it may be cleaned without interfering with the fire. An oval flue of iron
tubing passes through the boiler from the top, and passes out at the back, being
properly welded or rivetted; and for cleaning the same a stopper is provided in
the hot plate; this arrangement has for object to draw the flamme back under the
hot plate, making the plate hotter at this part.
The ordinary soot door is provided, and ovens are placed at the sides of the fire-
place as usual.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Robert Maguire in the Great Seal Patent Office on the 9th
February 1878.
WILLIAM ROBERT MAGUIRE, of the Firm of Maguire and Son, of Dawson Street,
in the City of Dublin, Ireland. "IMPROVEMENTS IN KITCHEN OR COOKING
RANGES."
This Invention consists in improvements in the construction of kitchen or cooking
ranges, whereby the consumption of fuel is economized and the general efficiency of
the range increased.
In carrying out my improvements I employ a front grating consisting of a series
of bars, the two end or side bars of which are continued or extended upwards and
serve as handles and also as stops, as herein-after described. This grating forms
the lower part of the front of the fire-place when in its vertical or normal
position.
In each of the said side bars is a slot, such slots catching or hanging on one
of the horizontal fire-bars of the range; the herein-before described grating is thus
pivotted on the said fire-bar; the upper fire-bar serves as a stop against which the
said side bars or handles rest when in a vertical position, and the upper bar is made
moveable so as to allow of the front grating being moved outwards when required
for cleaning away ashes, or otherwise.
Instead of the grating moving or swinging on a fixed bar as a centre, each of the
said bars may be formed with a pivot, such pivots taking into a slot and a hole
respectively in the sides of the range.
The front of the boiler forms the back of the fire-place, and the lower part thereof
is of a curved form, concentric with the bar on which the front grating revolves,
and this curved part forms the bottom of the fire-place when the front grating is
vertical. The boiler is provided with a cleaning or man-hole door in the boot, so
that it may be cleaned without interfering with the fire. An oval flue of iron
tubing passes through the boiler from the top, and passes out at the back, being
properly welded or rivetted, and for cleaning the same a stopper is provided in the
hot plate; this arrangement has for object to draw the flame back under the hot
plate, making the plate hotter at that part.
The ordinary soot door is provided, and ovens are placed at the side of the fire-
place as usual.
But to make my Invention better understood, I will now proceed to describe the
same by reference to the accompanying Drawing, in which Figure 1 is a perspective
elevation of a kitchen or cooking range constructed with my improvements; Figure
2, a transverse section of the same; Figures 3 and 4, detached front and side
elevations, of the swinging front grate or economizer; Figure 5, perspective view of

page_text: the same; Figure C, front elevation shewing the economizer formed with pivots,
and Figures 7 and 8, views of part of each side of the range, shewing the slot and
hole for receiving the said pivots; Figure 9, plan of handle for operating the
economizer.
Similar letters in all the Figures are used to represent similar parts.
The front grating or economizer, shewn detached at Figures 3, 4, and 5, consists
of a series of bars a, a, having the two end or side bars b, b, continued upwards so
as to form handles and stops, as shewn; c, c, are the slots in the side bars b, b, such
slots c, c, taking or fitting on the horizontal bar d of the range, so that the grating
or economizer is thus pivotted on the bar d; the upper bar e forms a stop, as shewn
in Figure 2, against which the side bars b, b, rest; this bar e is made removeable
so as to allow of the grating or economizer being turned outwards for cleaning out
the ashes or otherwise.
In the grating, shewn at Figure 6, instead of the herein-before described slots c, c,
for fitting over the bar d, it is provided with pivots f,f, which take into the hole g,
Figure 8, and slot h, Figure 7, in the sides of the range respectively; i is the front
of the boiler A, A, the lower part being concentric with the bar d or with the pivots
ff, as the case may be; j is the cleaning or man-hole door; k is the oval flue; l,
stopper in the hot plate m to allow of cleaning out the flue; n is the usual soot
door; 0, 0, ovens on either side of the fire-place. By these improvements it will be
seen that the employment of the swinging grate or economizer allows of the depth
of the fire being varied; for instance; when the full depth is required the front
grating or economizer is vertical, as shewn in Figures 1 and 2, but if it is required
to reduce the fire the ends of the handle or rod, shewn in Figure 9, are inserted in
the holes p, p, in the side bars b, b, and pulled forward, thereby moving the_grating
or economizer into a horizontal position, as shewn by the dotted lines x, x, Figure 2,
and thus forms the bottom bars or grating of the fire-place.
To clean out the ashes the bar e is removed, and the economizer moved into the
position shewn by the dotted lines y, y, Figure 2.
The man-hole door j being placed in the boot, as shewn, allows of the boiler being
cleaned out without interfering with the fire, while by the arrangement of the fluo
the flame of the fire is drawn back under the hot plate m, which is thus kept hotter
at this part.
Having thus described my Invention and the best means I am acquainted with
for carrying the same into effect, I wish it to be understood that I do not confine
myself to the precise details herein laid down and shewn in the Drawing, as they
may be varied without departing from the principle of my Invention, but what I
do claim is,-
Firstly. The construction and application to kitchen or cooking ranges of a
swinging or revolving front grate, arranged and operating substantially in the
manner and for the purposes herein-before described and represented in the accom-
panying Drawing.
Secondly. The arrangement and construction of the boiler having a cleaning door
placed in the boot and having a curved front in combination with the swinging
grate or economizer, substantially as herein-before described and represented in the
accompanying Drawing.
Thirdly. The oval flue arranged as and for the purpose herein-before described.
In witness whereof, I, the said William Robert Maguire, have hereunto set
my hand and seal, this Eighth day of February, in the year of our
Lord One thousand eight hundred and seventy-eight.
