Improvements in the Combination of Materials Employed in the
Construction of Chimney Pieces, Mantle Pieces, or the like
Structures.
1, JOHN ROBINSON (ROSTHWAITE, of South Stockton-on-Tees. in the County of
York, Ironfounder, do hereby declare the nature of this invention to be as
follows:
My Invention relates to chimney or mantle pieces or the like structures of the
kind employed as ornamental enclosures of stoves for heating rooms or apartments,
and has special reference to the combination of materials or parts forming the jambs,
lintel and shelf of such chimney or mantle pieces; my object being to freely employ
tiles or panels for artistic effect in the construction of such structures encased in
frame-work of cast iron or other suitable material in a particular manner, by which
combination of the parts the chimney or mantle piece may be designed to give a more
predominating effect to the tiles or panels and to afford greater protection to the
edges of the tiling than can be obtained in the usual mode of constructing such
articles.
In carrying my invention into effect in constructing the jambs 1 provide side plates
which are preferably cast iron plates which extend the full height of the jamb and
present a continuous edge or border line at each corner of the jainb face, cross pieces
are fitted in between the two side plates to hold them together and to form where
required transverse border or division lines to the tiling, which is fitted in between
the edges or border lines so provided and the side plates of the jamb. In some cases
small front flanges extend from the side plates of the jamb to or over the adjoining
edges of the tiling, which is fixed in to form a level surface between the side plates
or between the inside edges of the flanges extending therefrom, or is recessed to a
greater or less degree to suit the intended design of the stove.
In constructing the lintel I provide a similar arrangement of side plates extending
the full length of the lintel, one of which forms the under and the other the upper
side thereof, each of these side plates is furnished at either end with two hooks
which drop into slots or pockets provided in the inner side plates of the jambs, so as
to connect the jambs and lintel together as one structure; the tiling of the lintel
is fitted in between the upper and under side plates thereof in the manner herein-
before described with reference to the jambs, and extends to the side plates of
the jambs, or if the upper side plate be dispensed with, between the under side
plate and the shelf. The shelf which is preferably a cast iron plate of any suitable
configuration is supported in the usual manner on the jambs and lintel of the chimney
or mantle piece, and is hollowed out or recessed so as to leave a border line or edge
all round within which the tiling is fitted.
By the above described simple arrangement of the side plates and cross bars forming
the structure or frame-work of the chimney or mantel piece, tiles or panels can be
fitted into the said jambs, lintel and shelf, whether in flat or concave surfaces between
well defined edges or border lines of the protecting material so as to present a surface
to view in which the effect of the tiles greatly predominates over the material of which
the enclosing frame-work is constructed.

Improvements in the Combination of Materials Employed in the
Construction of Chimney Pieces, Mantel Pieces, or the like
Structures.
I, JOHN ROBINSON CROSTHWAITE, of the Union Foundry, South Stockton-on-
Tees, in the County of York, Ironfounder, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My Invention relates to chimney or mantel pieces or the like structures of the
kind employed as ornamental enclosures of stoves for heating rooms or apartments,
and has special reference to the combination of materials and arrangement of parts
forming the jambs, lintel, and shelf of such structures.
In the construction of chimney or mantel pieces of the kind to which my invention
refers, that is, in which ornamental tiles or panels are employed to enrich what may
be termed the structural material, it has hitherto been the practice to employ cast
iron or other metal as the structural material in the said jambs, liutel, and shelf,
but in such a manner as to afford limited facilities for enriching the appearance of
such structures by the combination therewith of some other material such as ornamental
tiling or panels except in the form of rectangular patches or areas inserted in recesses
provided in the faces of the different parts or segments which make up the mantel
or chimney piece. I am aware that in order to employ tiles or panels freely, chimney
or mantel pieces have been designed or constructed in which the employment of cast
iron or other metal as the structural material has been dispensed with, such mantel or
chimney pieces consisting of tiles or panels cemented or consolidated together without
frame work, in which mode of construction the strength of the cement or the like
material is relied on to hold the structure together.
The object of my invention is to combine with the strength and durability due to
a frame of cast iron or other rigid and suitable material an artistic effect of tiles or
panels in the face or frontispiece of the different parts of chimney pieces, mantel
pieces, or the like structures in the particular manner hereinafter described, in which
the parts or materials employed may be designed or arranged to give such pre-
dominating and uninterupted effect to the tiles or panels as may be desired, the
appearance of which is enhanced or improved by the continuous and unbroken border
lines formed by the edges or flanges of the sides and cross pieces of the frame work,
between which the said tiling or panelling is enclosed and protected.
And in order that my invention may be fully understood and readily carried into
effect I will now proceed to describe the same with reference to the accompanying
drawings, in which Figure 1 illustrates in front elevation a mantel or chimney piece
constructed according to my invention; Figure 2 is a corresponding sectional view
taken on line A A of Figure 1; Figure 3 is a sectional view of the lintel and shelf
taken on line B B; Figure 4 is a transverse sectional view of the jamb taken on
line CC; Figure 5 is a sectional plan of the jambs and lintel fitted together taken
on line D D Figures 6 and 7 illustrate in perspective in what manner the lintel and
jambs are connected together; and Figure 8 is an elevation showing a modification
for applying my invention in a less costly manner by a sacrifice of ornamental effect;
corresponding to which Figure 9 is a sectional view of the lintel and shelf taken
on line EE of Figure 8; Figure 10 is a transverse sectional view of the jamb taken
on line FF; and Figure 11 is a view in plan of the structure with the shelf removed
to illustrate in what manner the lintel and jambs are connected together. a¹ a² are
the jambs to which is fitted the lintel b in the manner hereinafter described with
reference to Figures 6 and 7; the shelf c is supported in the usual manner upon the
jambs a a² and the lintel b. The jambs a¹ a² are each furnished with two side plates
d' d' d' d², which are preferably cast iron plates and extend the full height of the
jambs, thus presenting a continuous edge or unbroken border line at each corner.
of the jamb face to protect the edges of the tiles or panels which are fitted in and
cccupy the space between the side plates. In some cases small front flanges e of an
с

page_text: ornamental character extend from the edges of the side plates d' d² to or over the
adjoining edges of the tiling. I secure these side plates d' d' d² ² together by
means of cross pieces f¹ƒƒ³ f4, which while serving the purpose of holding the
frame work of the structure together form where required transverse border or
division lines of an ornamental character to the tiling which is fitted in between the
edges or border lines so provided and the side plates d' d² of the jambs. The lintel b
is constructed on the same principle as the jambs a¹ a², by having a side plate g
extending the full length of the underside of the lintel, and in some cases a corre-
sponding side plate extending along the upper side thereof, each side plate having
a front flange e formed on the edge if required in keeping with the flanges already
described as extending from the sides d¹² of the jambs; but in other cases the
upper side plate is dispensed with by an arrangement as illustrated in Figures 1
and 3, in which a plate h extending underneath the shelf c, to which it is secured
by a screw i, or any other suitable means, serves to protect the upper edge of the
tiling and in combination with the underside of the shelf c serves as a substitute for
the upper side plate of the lintel; the tiling of the lintel is fitted in to occupy the
space between the upper and underside plates thereof, or between the shelf c and the
underside plate g in the manner hereinbefore described with reference to the jambs,
and extends endwise to the side plates of the jambs as illustrated in Figure 1. The
shelf c, which is preferably a cast iron plate of any suitable design, is supported in
the usual manner on the jambs and lintel of the. chimney or mantel piece, and is
hollowed out or recessed to any required degree to suit the intended design so as to
leave an unbroken border line or edge c' in keeping with the border lines or continuous
edges as already described with reference to the jambs and lintel, the space within
which is occupied by the tiling. In order that the tiles or panels may be rigidly
secured in position within the side plates and cross pieces of the frame work of the
structure, I provide a layer of cement or the like material to form a bed behind the
tiles in every available position, which thus enables the tiles to be built into the spaces
between the frame work so as to form a light and serviceable mantel or chimney
piece. 1 furnish the side plates of the lintel at either end with two hooks j' j², which
drop into slots or pockets k¹ k², provided in the inner side plates of the jambs as
clearly illustrated in Figures 6 and 7, and thus effect a reliable and strong connection
between the said jambs and lintel.
Figures 8, 9, 10 and 11 illustrate a modification in the construction of my
improved chimney or mantel pieces, the object being to obtain the same advantages
as already described with reference to the chimney or mantel piece illustrated in
Figure 1 at a reduced cost effected by the sacrifice of ornamentation for simplicity.
In this case the shelf c may be a cast iron plate of any suitable design as already
described with reference to the more elaborate mode of construction illustrated in
Figures 1 and 3, and is similarly hollowed out and recessed to suit the intended
design. The jambs a' a², instead of being made up of separate side plates united
together by ornamental cross pieces in the manner herein before described, consist of
sides d¹ d² united end wise as one open casting with top and bottom cross plates d³,
which open casting forms the frame or continuous border line within which is fitted
the panels or tiling. The lintel 6 is similarly constructed, the sides g being united as
one casting with the end plates 1, which forms the frame within which is fitted the
panels or tiling slots through the end plates of the lintel correspond to lugs or
hooks at the back of the jambs to secure the lintel and jambs together. The layer of
cement in which the tiles or panels are embedded, which in some cases may be thin,
is supported by cross bars m, which are cast on the back of the jambs and lintel at
suitable distances apart.
It is of course obvious that by the above described simple arrangement of the
side plates and cross pieces forming the structure or frame work of the chimney or
mantel piece, tiles or panels can be fitted into the said jambs, lintel, and shelf in
dat, concave, or any other recessed surfaces the shape or design of the tiles will
admit of, between well defined and unbroken edges or continuous border lines of the
protecting material, so as to present a surface to view in which the effect of the tiles

page_text: greatly predominates over the cast iron or other material of which the enclosing
frame work is constructed.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same may be carried into effect and applied to
the construction of chimney or mantel pieces or the like structures of the kind
employed as ornamental enclosures of stoves, what I claim is :-
Firstly The combination of materials and structural arrangement in which the
face or frontispiece of the several parts or each part consists of tiles or panels laid in
or enclosed within border lines formed by the edges or flanges of a frame work of
cast iron or other suitable material, substantially as and for the purpose as hereinbefore
described with reference to the accompanying drawings.
Secondly The general arrangement and combination of parts, substantially as
hereinbefore described with reference to Figure 1.
Thirdly The general arrangement and combination of parts, substantially as
herein before described with reference to Figure 8.
