COMPLETE SPECIFICATION
A New or Improved Bond or Tie for Ordinary and Cavity Walls
I, THOMAS TAYLOR of 18 Corby Street, Birch Street, West Gorton, in the
City of Manchester and County of Lancaster, 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 relates to a bond or tie for ordinary and cavity walls and its
object is to provide one which may be cheaply and simply constructed and will
obtain and maintain a secure and permanent seating in the wall and which may if
desired be furnished with means for shedding any water instead of conducting it
from one wall or part of a wall to another
The
A bond or tie constructed according to this invention consists of a wire of
suitable gauge or section having its ends twisted or otherwise secured together and
which is bent or formed into either an oblong square oval circular or other desired
shape or frame Opposite ends or sides of this frame are gripped by hand or
suitable rotary mechanical devices and are rotated in opposite directions
result of the rotary motion is to cause the other ends or sides of the frame to cross
one another, and to twist round one another The rotation is stopped after
a sufficient number of turns leaving the ends on sides of the frame which were
gripped and which will form the ends of the bond or tie still open to key with the
mortar when in the wall
It is preferred that the twisted ends of the wire forming the frame be contained
within the twisted part of the bond or tie and project downwards when the bond is
in place thus forming a point from which water will dip or be conducted away
The passage of water to the projecting drip point is assisted by the convolutions
of the twisted part of the boud, these convolutions also forming or tending to form
additional drip points
In order that my invention may be moit clearly understood I have hereto
appended a sheet of drawings reference to which is made hereinafter
Figure 1 is a plan of one form of tie in the first stage of construction
Figure 2 is a plan of the same tie in the second stage of construction
Figure 3 represents an elevation of the tie in the second stage of construction
As shewn in the diawings a piece of wie A of suitable gauge or section is
formed into an oblong fiame its ends being twisted together at B Two opposite
ends or sides ab of the wire are then gripped and rotated in opposite directions so
that the other sides or ends c d cross one another and twist round one another as
represented in Figure 2 The ends a bare thus left open to key with the mortar
when the tie is in place I he twisted ends B of the wire preferably come within
the convolutions of the tie or bond and form a drip point as illustrated by the
elevation Figure 3
It is preferred to treat the tie or the metal from which it is formed in such
a manner as to protect it from corrosion, as for example, by immersing it while hot
in melted pitch
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 A bond or tie for cavity and ordinary walls constructed substantially as and
for the purpose hereinbefore described and as illustrated by the accompanying
dran inges
