of Paris France
Sealed the 12th December 1879, and dated the 16th June 1879.
PROVISIONAL SPECIFICATION left by the said Thomas James Smith at the
Office of the Commissioners of Patents on the 16th June 1879.
THOMAS JAMES SMITH, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents. "IMPROVED MEANS OF
FACILITATING AND REGULATING THE UTILIZATION OF THE RADIANT HEAT FROM
OPEN FIRE GRATES OF ALL KINDS." A communication from abroad by Georges
Jean Charles Beaulavon, of Paris, France.
The object of this Invention is improved means of facilitating and regulating the
utilization of the radiant heat from open fire grates of all kinds placed or set in any
description of fireplace, such heat being applied to domestic purposes.
In this Invention the aim in view is to reduce the source of heat necessary for
heating the apartment, as also for the preparation of all sorts and kinds of food,
heating liquids, solids, roasting or broiling meat and fish, drying linen, and other
purposes, to a single fixed fire in one single open fire grate, and in such a manner
that the various uses of the radiant heat supplied by one single fire applied to such
a variety of purposes shall not vitiate the air of the apartment by its mingling
with the disagreable or noxious gases or smoke which are drawn outside by the
chimney.
The means employed consist in a series of apparatus specially arranged for their
adaptation (by means of tenons with which they are provided) to sockets suitably
distributed over the grate, open stove, fire hearth dogs, and other parts, such stoves
or grates consuming either mineral or vegetable fuel.
These sockets may be formed and applied to all existing kinds of grates. When
applied to fire-hearth dogs they are placed either on the backs or uppermost parts,
or on the heat or other device usually formed on their front ends.

page_text: When applied to fire grates and open roasting stoves they are arranged on the
ront part, where they are mingled or blended with the ornamentation, or on the
bars or the side cheeks of the grates.
Each of the special parts which are provided with a tenon intended to engage in
the sockets above mentioned is arranged so as to fulfill a special purpose; one of
these serves to maintain or support, in front of or on the fire, all kinds of receptacles
containing all sorts of substances.
Another arrangement, called a "spit carrier," supports a roasting rack before the
fire. Another, called a grill or grid stand, supports an iron or enamelled grill over
the fire. Another, called a toasting grid, holds the bread to be toasted in front of
the fire, and may also serve to hold plates, flat irons, tools, and any other object
which requires to be presented to the fire.
Finally, another arrangement called an elbow acts as an intermedium between
the sockets on the grates, fire dogs and stoves, and the tenons of the various special
arrangements above described. This elbow piece, which is provided with a tenon
at one end and a socket at the other, furnishes a double joint which permits free
movement of the various arrangements, and allows any convenient position on, in
front of, or around the fire to be taken up.
All the sockets on the grates, elbow pieces, and other parts, and all the tenons on
the grill stand, spit carrier, elbows, and the various other arrangements, are formed
of the same size, so that all the apparatus or arrangements of this system are
interchangeable.
Instead of placing the sockets on the grate, fire dogs, or stove, they may be placed
on the various special arrangements, and vice versa.
For the purpose of adapting this Invention to ordinary stoves not constructed
according to this system, it is only necessary to fix or place sockets having tangs or
shanks in a bolt hole by means of a snug screw and nut.
This Invention also includes a fire screen or fender held or supported vertically
in front of the fire place by an elbow, a tenon on the screen taking into the socket
of the elbow, which latter in its turn engages into the socket on the grate. This
screen, besides preventing dangerous proximity to the fire, may also serve to dry
linen or other objects.
The effective operation of this Invention is independent of the shapes or forms of
the constituent parts, as also of the material employed in their construction.

the said Thomas James Smith in the Great Seal Patent Office on the 16th
December 1879.
THOMAS JAMES SMITH, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents. "IMPROVED MEANS OF
FACILITATING AND REGULATING THE UTILIZATION OF THE RADIANT HEAT FROM
OPEN FIRE GRATES OF ALL KINDS." A communication from abroad by Georges
Jean Charles Beaulavon, of Paris, France.
The object of this Invention is improved means of facilitating and regulating the
utilization of the radiant heat from open fire grates of all kinds placed or set in any
description of fireplace, such heat being applied to domestic purposes.
In this Invention the aim in view is to reduce the source of heat necessary for
heating the apartment, as also for the preparation of all sorts and kinds of food,
heating liquids, solids, roasting or broiling meat and fish, drying linen, and other
purposes, to a single fixed fire in a single open fire grate, in such a manner that the
various uses of the radiant heat supplied by one single fire applied to such a variety
of purposes shall not vitiate the air of the apartment by its mingling with the
disagreable or noxious gases or smoke which are drawn outside by the chimney.
The means employed consist in a series of appliances specially arranged for their
adaptation (by means of tenons with which they are provided) to sockets suitably
distributed over the grate, open stove, fire licarth "dogs," or other parts, such stoves
or grates consuming either mineral or vegetable fuel.
These sockets may be formed and applied to all existing kinds of grates. When
applied to fire hearth dogs they are placed either on the backs or uppermost parts,
or on the head or other device usually formed on their front ends.
When applied to fire grates and open roasting stoves they are arranged on the
front part, where they are mingled or blended with the ornamentation, or on the
bars or the side cheeks of the grates.
Each of the special parts which are provided with a tenon intended to engage in
the sockets above mentioned is arranged so as to fulfil a special purpose; one of
these serves to maintain or support in front of or on the fire all kinds of culinary
receptacles.
Another appliance, called a "spit carrier," supports a roasting rack before the fire.
Another, called a grill or grid stand, supports an iron or enamelled grill over the
fire. Another, called a toasting grid, holds the bread to be toasted in front of the
fire, and may also serve to hold plates, flat irons, tools, or any other object which
requires to be presented to the fire.
Finally, another appliance called an elbow acts as an intermedium between the
sockets on the grates, fire dogs and stoves, and the tenons of the various special
arrangements above described.
This elbow piece, which is provided with a tenon at one end and a socket at the
other, furnishes a double joint which permits free movement of the various arrange-
ments, and allows them to occupy any convenient position on, in front of, or around
the fire.
All the sockets on the grates, elbow pieces and other parts, and all the tenons on
the grill stand, spit carrier, elbows, and the various other appliances, are formed
of the same size, so that all the apparatus or arrangements of this system are
interchangeable.
Instead of placing the sockets on the grate, fire dogs, or stove they may be placed
on the various special appliances, and vice versa.
For the purpose of adapting this Invention to ordinary stoves not constructed
according to this system it is only necessary to fix or place sockets having tangs or
shanks in a bolt hole by means of a snug, screw, and nut. These sockets or tenons

page_text: may be applied to any grate, range or stove, or they may be placed in any useful
position.
This Invention also includes a fire screen or fender held or supported vertically in
front of the fire place by an elbow, a tenon on the screw taking into the socket of
the elbow, which latter in its turn engages into the socket on the grate. This screen,
besides preventing dangerous proximity to the fire, may also serve to dry linen or
other objects.
The effective operation of this Invention is independent of the shapes or forms of
the constituent parts, as also of the materials employed in their construction.
The annexed Drawings show as examples several appliances used in carrying out
this Invention. Figure 1 is a front view of an open fire grate X provided with a
series of sockets a for the reception of the tenons on the various special appliances.
Figure 2 is a plan, and Figure 3 a cross section. Figure 4 is a fire-hearth dog
provided at a with a socket for the reception of the various special appliances.
B are spit carriers for roasting, provided with tenons t. C is a grill or grid for
broiling, also provided with a tenon t. D (Figure 5) is a rack for toast, warming
plates, and other purposes, in which the tenon t is shown. E is a stand or "trivet,'
on which saucepans, glue pots, flat irons, and other articles to be heated may be
stood. This stand or "trivet" also pivots on a tenon, and may be triangular or any
other shape. F is an elbow piece having a socket & at one end and a tenon t at the
other. This appliance serves as an intermedium between the special appliances and
the fire grates and fire hearth "dogs." In conjunction with the special appliances
it forms a double pivoted joint which permits its adaptation to any desired position
over the fire, and it also serves for attaching a fire guard on which linen may bo
hung to dry. H is a kettle or boiler having a base or tenon I which enters into
the opening in the fire hearth dog.
If it is desired to utilize the grates at present in use it can also be effected by
fixing ears a to them by means of bolts b (Figures 6 and 7), the ears serving to
support the pivoted appliances F arranged in the manner above described.
And having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that I claim as the Invention of my foreign
correspondent the improved arrangements of open fire grates applicable to culinary
and other domestic uses, according to the conditions above described and shown in
the Drawings.
In witness whereof, I, the said Thomas James Smith, have hereunto set my
hand and seal, this Sixteenth day of December, One thousand eight hundred
and seventy nine
