An Improved Building Brick.
I, DANIEL GRIFFITHS, Granville House, Pontypool, Monmouthshire, Colliery
and Brickworks Accountant, &c., do hereby declare the nature of this invention
to be as follows:-
Figure 1 on the annexed drawing gives the end view of the brick. Figure 2
on the same drawing gives a longitudinal section of the brick, shewing a channel
running through it."
The channel which is indicated by the letter A on Figs. 1 and 2 may be circular
square or any regular shape.
What I claim as the special feature of this patent is the hollow space running
lengthways through the brick, the advantages of which are these. It reduces
the weight and so cheapens the production of the bricks. It enables hollow walls
to be constructed throughout a building, the header bricks of 9 inch and thicker
walls yielding a good key for the plaster cement or stucco, the walls being thus
rendered sound proof as well as rain proof. The brick may further be used as an
outside facing brick in conjunction with solid bricks, i.e. solid bricks may be
used as headers while hollow bricks might be used as stretchers, and so enable
partially hollow walls to be constructed.

DANIEL GRIFFITHS.
I, DANIEL GRIFFITHS, of Granville House, Pontypool, in the County of Mon-
mouth, 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 relates to an improved brick for building purposes the object
being to provide a brick of improved construction that will be lighter without
decreasing its external dimensions, one more casily and uniformly hardened
during firing and which will also possess better damp and sound resisting properties
than is at present the case.
My invention consists essentially in forming the brick with a longitudinal or
transverse channel or channels runing entirely through it, such channels being
preferably circular, oval, square, polygonal, or some such regular shape though
an irregular shaped channel may be employed.

page_text: The invention will be described with reference to the accompanying drawings
in which,
Fig. 1 is an end view of a brick with an oval channel running longitudinally
through it.

Fig. 3 an end view of another brick with two transverse channels running
through it,

Fig. 5 a view showing the two kinds of bricks used in conjunction.
In carrying out my invention the bricks may be made of any suitable material
and of the usual external dimensions common in the trade. Internally they are
provided with one or more channels A running longitudinally or transversely
through them. This channel or channels, may be oval as shown or of any other
regular shape, such as circular, rectangular, or polygonal for instance though it
may be of any other shape suitable for the purpose.
Bricks as shown in Figs. 1 and 2 may be used both as headers and stretchers
in inside and outside walls that are to be plastered, in which case the channel of
the header would form a good key for the cement, stucco or plaster. In outside
walls that are not to be plastered the same brick might be used as a stretcher
with a solid brick as a header. Or instead of a solid header a brick as shown in
Figs. 3 and 4 could be used, which arrangement is shown in Fig. 5, thus making
the channels in the walls continuous while presenting a solid exterior, and re-
quiring solid stretchers and headers only at quoins and angles. The bricks may
be made by a wire cut machine at a very small additional cost to existing
arrangements.
Bricks constructed as shown possess the following advantages: -The weight
of the bricks is lessened without reducing the bulk and thereby the costs of pro-
duction and transit are also reduced; while being burnt in the kilns the channels
allow the fire to pass through the interior of the bricks and so enable them to be
burnt harder with a reduced quantity of fuel; the arrangement of the channels
in the walls which these bricks make possible helps to intercept the damp and
to make the walls damp-proof.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is;-
1. Bricks for building purposes provided with one or more channels running
longitudinally or transversely through them substantially as and for the purposes
described.
2. Bricks for building purposes constructed and arranged substantially as
described and as shown in the accompanying drawings.
