PROVISIONAL SPECIFICATION.
An Improved Construction of Tiebricks.
FRANCIS WILLIAM HOLLOWAY Paddock Hall Road Haywards Heath Sussex
Building Surveyor and EDWARD PHILP BASTIN 49 Finsbury Pavement London
Engineer do hereby declare the nature of this invention to be as follows:-
This invention consists in "An Improved Construction of Tie bricks," which are
more especially suited for use in constructing the angular piers of bay windows and
the like, but are applicable to other purposes. We usually form the tie of 3
separate bricks; two being of unequal size, the third by means of a tongue forming
a bond with the other two in addition to the adhesion of the mortar or cement
employed.
The external face of the bricks may be moulded to any desired shape and
they are so designed as to overlap the joint on their being reversed at each
course thereby forming a bond; but at the same time as each brick by reversing
hand repeats itself on each course the contour of the exterior moulding as well as
the interior face is preserved.
The upper and underside of each brick is usually "frogged" and sufficient space
left between the tongue and recess to permit the mortar or cement to obtain a firm
hold. In some cases a recess is formed in the inner face of each brick forming the
"tie" within which we place a vertical bar of iron of cruciform or other suitable
sectional shape which is then secured by mortar or cement so as to obtain additional
rigidity.

COMPLETE SPECIFICATION.
An Improved Construction of Tiebricks.
FRANCIS WILLIAM HOLLOWAY, Paddock Hall Road, Haywards Heath,
Sussex, Building Surveyor, and EDWARD PHILP BASTIN, 49 Finsbury Pavement,
London, Engineer, 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 in "An Improved Construction of Tiebricks" which are
more especially suited for use in constructing the angular piers of bay windows and
the like, but are applicable to other purposes. We usually form the tie of 3
separate bricks, two being of unequal size, the third by means of a tongue, forming
a bond with the other two in addition to the adhesion of the mortar or cement
employed. The external face of the bricks may be moulded to any desired shape,
and they are so designed as to overlap the joint on their being reversed at each
course thereby forming a bond, but at the same time as each brick by reversing
hand repeats itself, on each course the contour of the exterior moulding, as well
as the interior face is preserved.
The upper and underside of each brick is usually "frogged" and sufficient space
left between the tongue and recess to permit the mortar or cement to obtain a firm
hold. In some cases a recess is formed in the inner face of each brick forming the
"tie" within which we place a vertical bar of iron of cruciform or other suitable
sectional shape, which is then secured by mortar or cement so as to obtain additional
rigidity.

page_text: To enable our invention to be clearly understood we will now describe the same
by means of the accompanying drawing in which,
Fig. 1. is a plan of one side of an ordinary bow window having angular piers.
Fig. 2. shews a plan of the next course, above that shewn in Fig. 1.
The tie bricks are lettered respectively A. B. C. see Fig. 1. but in the next
course, shewn in Fig. 2. the position of the bricks is altered, so as to overlap the
cement joint D, shewn in dotted lines, and form a bond; but at the same time
preserving the contour of the exterior moulding, as well as the interior faces, an
additional tie is also formed by the tongue of brick C.
The upper and underside of each brick is usually frogged as at E, and sufficient
space left between the tongue and recess, to admit the mortar or cement D, to
obtain a firm hold.
In some cases for the purpose of obtaining additional rigidity a recess F is
formed in the face of one or more than one brick forming the tie, and within this
we place a vertical bar of iron G, of cruciform or other suitable shape which is
then secured by mortar or cement so as to obtain additional rigidity.
We do not confine our improvements in tie bricks to the exact shapes or number
specified and shewn in the drawing, as both are dependant upon the exterior
contour, and the face of the required work.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The particular combination herein described, whereby a set of 3 or other
suitable number of bricks are so arranged as to preserve the required external
contour, and at the same time are interlocked by a tongue which forms an
independent tie, in the manner set forth.
2. The particular construction herein described whereby each brick, when
reversed at each course overlaps the mortar, or cement joint and preserves the
external contour of the pier or other face of work.
3. The application and use of an iron bar of cruciform or other shape cemented
within a recess formed in the inner face of a set of bricks constructed, and fulfilling
the purposes described.
