PROVISIONAL SPECIFICATION.
A New or Improved Brick for Building and other Purposes.
We, ALFRED GRAYSON, Westfield House, Barnes, Builder, and WILLIAM JAMES
SPRATLEY, 32, Bridge Road, Hammersmith, London, Chairman of Graysons
Double Dovetail Fixing Brick Syndicate Ltd., do hereby declare the nature of this
invention to be as follows:-
1
This invention consists of a new or improved brick for building and other
purposes, and is an improvement upon my Patent No. 1602797, the object being
to provide a ready means for the insertion of wood or other matter into the
wall, so as to enable the desired object to be fixed thereto. In carrying out.
our invention, we provide what we term a brick which is formed of suitable
material such as iron or metal and is shaped so as to represent the desired frame.
In the interior of this frame, we provide suitable shaped projections preferably
wedge shaped, so that when a block of wood or other suitable material is pressed
into the interior of the brick, the wedge shaped projections will tend to secure
the same, as it will be seen that it will cause an expansion or pressure of the
substance such as wood against the sides of the interior of the brick. We may
state that we do not confine ourselves to the shape, size, configuration of the
brick or frame, or the shape, size, or position of the wedges or projections.
Dated this 30th day of May 1899.

ALFRED GRAYSON, Westfield House, Barnes, Builder, and WILLIAM JAMES
SPRATLY, 32, Bridge Road, Hammersmith, London, Accountant, 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:-
This invention consists of a new or improved brick for building and other
purposes, and is an improvement upon my Patent No. 16027 1897, the object being
to provide a ready means for the insertion of wood or other material into the
wall, so as to enable the desired object to be fixed thereto. In carrying out
our invention, we provide what we term a brick which is formed of suitable
material such as iron or metal and is shaped so as to represent the desired frame.
In the interior of this frame, we provide suitably shaped projections preferably
wedge shaped, so that when a block of wood or other suitable material is presseil
into the interior of the brick, the wedge shaped projections will tend to secure

page_text: the same, as it will be seen that it will cause an expansion or pressure of the
substance such as wood against the sides of the interior of the brick. We may
state that we do not confine ourselves to the shape, size, configuration of the
brick or frame, or the shape, size, or position of the wedges or projections.
For the purposes of illustration, we will now refer to the annexed drawings
in which:
Figure 1 is a plan view of an improved brick or frame.
Figure 2 cross section through line X Y in Figure 1.
a is the frame formed of metal such as cast iron, and it will be seen that it is
so shaped as to provide the chambers or enclosures bbb. The top edges of the
frame as shown at e in Figure 2, are not so wide as the bottom edge as shown
at f in Figure 2, or in other words the sides or parts of frame a are tapered.
This tapering is for the purpose of locking or more securely holding the brick or
frame in the cement or other suitable material when in position, the block of
wood or material is driven into the space marked d and is caused to be effectually
retained therein through the action of the tapering wedge shaped projections c.
These projections c are placed at the required part of the frame and their action
is to expand the material when being driven into this space against the sides
thereof, from the top of the frame and so securely lock it therein.
If this brick is placed, for instance in the case of a chimney, so that the side a¹
is towards the interior of the chimney, it will be seen that the required article
will be fixed to the block which is driven into the space d, and this block will be
insulated through the cement which will enter the chambers or recesses b, b, b,
and prevent the action of the heat which might arise from the inside of the
chimney acting directly upon the block aforesaid. Of course the length and size
of the pieces c will be varied as required and the number increased, and these
pieces c may be cast integral with the brick or frame or may be attached thereto
in any convenient manner. The principal feature of our invention is to dis-
pense with the necessity of knocking a hole in the wall, and inserting a wooden
plug therein as this is never secure and also in the event of the plug projecting
for instance in the case of a chimney into the interior thereof, there is a danger
of fire, whereas by my invention when once the brick or frame carrying the
block of wood is being inserted in position, the block of wood is insulated and
cannot be withdrawn without the removal of the brick or frame. This insertion
may take place during the course of building if the parts at which the blocks
are required are known. Although we have mentioned cement for the purpose
of filling the recess or enclosures b, it will be readily understood that we may
employ in place thereof a suitable fire proof material.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what we
claim is:-
1. The improved brick or frame substantially as described and illustrated herein
and for the purpose set forth.
2. A frame for use as a brick formed of suitable material, such as metal and
being tapered as described. A space for the insertion of a block of wood or other
suitable material, tapered wedge shaped projections in said space for the purpose
of locking a block of wood or other suitable material when driving therein, sub-
stantially as described and illustrated herein and for the purpose set forth.
Dated this 14th day of July 1899.
