Complete Specification Accepted, 24th Aug., 1888
I, JOHN KNIGHT CHAMPION, of 4 Sydney Terrace, Newquay, Cornwall, Accountant,
do hereby declare the nature of this invention to be as follows:
These Lock Bricks consists of an ordinary brick having a dovetail shaped opening
in one side, whereby the said Brick is locked io another similar Brick placed parallel
with the same by means of a cross Brick or Tic, made to fit into the said dovetail
shaped openings at each end.
The said cross Bricks or Ties are made of such a length as to keep the two parallel
Bricks at a little distance from each other, consequently there will be a hollow space
in the centre between the said parallel Bricks.
This hollow space may be made any width by increasing the length of the cross
Brick or Tie.
In addition to the cross Brick or Tic, I make on the upper part of each Brick a
longitudinal Bead, and in the under part of the same Brick a longitudinal Grove
to fit the said Bead, for the purpose of locking one Brick on another.
In the Bricks to be used as Quoins, I make a return or right-angle Bead and Grove,
instead of a longitudinal Bead and Grove, since the Quoin Bricks will have no other
locking

the nature of this invention for LOCK BRICKS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
These Lock Bricks consist of an ordinary Brick having a dovetail shaped opening
in one side, whereby the said Brick is locked to another similar Brick placed parallel
with the same, by means of a cross Brick or Tie made to fit into the said dovetail
openings at each end.
The said cross Bricks or Ties are made of such a length as to keep the two parallel
Bricks at a little distance from each other, and in building as no two cross Bricks or
Ties comes direct one on another there will be a hollow space between the said parallel
Bricks, which, combined with strength" gives greater facilities for ventilating
purposes than any other known method of Brick building.
I also make on the upper part of each Brick a longitudinal Bead or Tongue, and in
the under part of each Brick a longitudinal Groove or Recess to fit the said Bead or
Tongue, for the purpose of increased steadiness in the building.
In the Bricks to be used as Quoins, I make a return or right-angle Bead or Tongue
on one side, and in the opposite side a corresponding Groove or Recess,
The whole as shown in drawings.
