PROVISIONAL SPECIFICATION.
Improvements in or relating to Blocks for Building Arches, Counter-
hearths, Flooring, or the like.
I, CHARLES GREEN, of Wellgate House, Rotherham, in the County of York,
Builder and Contractor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to blocks for trimmer arches, counter hearths, fireproof
flooring or the like.
Within the recess
or
or space for the hearths the like I place suit-
able concrete, cement, blocks, or block of metal or material of any suitable size
and shape, and so moulded as to have male and female lips or suitable grooves so
that they fit one another when placed in position thus forming a perfect joint.
Of course it is quite understood that the side fitting nearest to the sides of the
recess or space are square with the aforesaid recess or space and the ends of the
blocks are tapered or shaped to suitable bearings which are placed to receive them.
I am fully aware that brick blocks formed of clay or like substances are already
used and also ashlar or other stones, but they are not lipped or grooved to make a
fire-proof joint.
My blocks can be made of any suitable thickness so that the hearths can have
the usual tiling or hearth-stones laid upon them.
In the case of large buildings where it is necessary to have fire-proof floors
(which are generally constructed by a series of iron or steel girders), instead of the
usual concreting or cementing which is first laid on a flooring of wood, the wood
being displaced after the concrete or the like is set, mould my block of the desired
size with the male and female lips or grooves, the ends being also shaped to suit
the webs of the girders; these blocks are placed one after the other as many as are
necessary.
I may pour liquid cement or concrete over the said joints thus obtaining a hard
and fast cementing together of the blocks and a perfect fire-proof floor.
The under part of the aforesaid blocks is usually indented with any suitable
indentation or pattern so as to hold the plastering of the ceiling for the room below
if necessary.

Improvements in or relating to Blocks for Building Arches, Counter-
hearths, Flooring, or the like.
I, CHARLES GREEN, of Wellgate House, Rotherham, in the County of York,
Builder and Contractor, do hereby declare the nature of this invention, and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This invention relates to blocks for arches, trimmer arches, counter-hearths,
fireproof flooring or the like.
In the accompanying drawings:-
Fig. 1, is a plan of a counter-hearth with blocks in position therein;
Fig. 2 is a section of the same on the line 2-2 of Figure 1 and
Fig. 3 a section on the line 3-3 of Fig. 1.
Fig. 4 is a view of the underside of the block.
Fig. 5 a plan and
Figs. 6 & 7 side and end elevations thereof respectively.
Fig. 8 is a sectional side elevation showing a block in position between joists
for arches or fireproof floors.
Like letters indicate like parts throughout the drawings.
In the construction of a counter-hearth which is formed in the usual manner as
a structure of beams or bars A, A¹ & A² receiving their support from the walls B
I nail, fasten or fix by any suitable means a strip C or an angle-iron to the beam A¹.
On the wall side 13 underneath the hearth I fasten a support D preferably of
wood or iron and on the top of the same, fix or fasten by any convenient means
another strip E corresponding with the strip C and of any desired shape to form
therewith a bed or support for the blocks F.
These blocks are constructed to have male and female lips or suitable tongues G
so that they fit into or engage one another when placed in position in the manner
indicated by Fig. 3 forming a perfect joint.
Instead of being carried on the support D the blocks can be fitted into the
masonry by recessing it or cutting it out to receive them.
It will readily be understood that the outside ends F2 of a series of blocks can be
made square and the sides I of the same can be made shaped to any desired angle
so as to correspond with the angle of the strips C and E or the masonry and take
a perfect bearing thereon.
grooves
On the underside of the blocks FI
may form any suitable
tations if necessary for the purpose of holding up the plastering of the ceilings;
F4 or inden-
these grooves should be so disposed as to constitute an ornament or design on the
block.
In the case of fireproof flooring or arches the blocks F can be laid between joists H
in the manner indicated in Fig. 8 and formed of any suitable design and accord-
ing to template if necessary so as to be easily placed in position.
My blocks can be made of brick, clay, stone, iron, wood, or any other suitable
metal or material and formed or moulded to any suitable size or design according
to requirements and to fit neatly and accurately into their positions having their
edges either square, angular or as may be convenient and also having the male and
female lips or tongues G.
After these blocks F are placed in position I may pour liquid cement or concrete
over them or their joints so as to maintain a hard and fast cementing and ensure a
perfect fireproof flooring.
Again in the case of counter-hearths I preferably curve the tops F3 of the
blocks F and also cement, concrete or fill in the space forming the base of the
hearth after which any suitable tiling, stonework, cement or concrete can be placed
thereon so as to form a level hearth and also a fire proof one.
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. In arches, counter-hearths, trimmer arches, floors or the like the employment
of blocks F having male and female lips or tongues G substantially as hereinbefore
described

page_text: 2. In arches, counter-hearths, trimmer arches, floors or the like the employment
in combination with blocks F of strips such as C & E of such cross section that
the blocks will tit close against them for the purpose described.
3. In arches, counter-hearths, trimmer arches, floors or the like the employment.
of blocks F engaged at their ends in recesses, in walls or the like for the purpose
described,
4. Blocks such as F having male and female lips or tongues. and ornamental
designs formed of grooves or indentations F.
