I ALLAN EDWIN HOWARD HARRISON, of St. George's Cathedral Southwark, in
the County of Surrey Clerk of Works, do hereby declare the nature of this invention
to be as follows:-
My invention has reference to improvements in the methods of laying and bonding
together, the wood blocks in wood block flooring.
My object is to prevent the separation of the said blocks, and also to prevent them
leaving the substratum, or bed upon which they are placed.
For this purpose, I take blocks of any size, and cut a groove all round (on all four
sides) making the lower portion of the block, narrower than the upper. As the means
of bonding the blocks together, I insert a metal tongue (ordinary hoop iron for
example cut in the required lengths).
In carrying out my invention the blocks are laid upon the usual bed of mastic
composition, so that after the metal tongue is inserted in the grooves of the said
blocks, the composition being forced up, it surrounds the narrow or lower portion of
the blocks, thus preserving them from damp, and tends also to increase the security of
the joint.
My improvements are applicable to any design of wood block flooring.
I am aware that various methods have from time to time been tried of securing
wood block together, by means of small plugs or dowels, inserted in each end of the
block, and again I am aware of such blocks being secured together, by wooden tongues,
inserted in grooves, therefore I do not propose to claim such longitudinal grooving, or
the principle of tongue fastening as being novel.
Dated this 5th day October 1887.

page_text: I, ALLAN EDWIN HOWARD HARRISON, of St. George's Cathedral Southwark, in
the County of Surrey Clerk of Works 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:-
My invention has reference to improvements in the methods of laying and bonding
together, the Wood Blocks; in wood block flooring.
My object is to prevent the separation of the said Blocks, and also to prevent them
leaving the substratum, or bed upon which they are placed.
For this purpose, I take blocks of any size, and cut a groove all round (on all four
sides) making the lower portion of the Block, narrower than the upper. As the
means of bonding the blocks together, I insert a metal tongue (ordinary hoop iron for
example cut in the required lengths).
In carrying out my invention the blocks are laid upon the usual bed of mastic
.composition, so that after the metal tongue is inserted in the grooves of the said
Blocks, the composition being forced up, it surrounds the narrow or lower portion of
the Blocks, thus preserving them from damp, and tends also to increase the security of
the joint.
In order that my said improvements may be more clearly understood and readily
carried into effect, I will proceed to describe the drawings hereunto annexed.
Figure 1 represents a section of the Wood Block flooring, illustrating the method
of bonding the blocks together-A is the groove, B, the metal tongue, C the mastic
composition, and D & E, the screedings & concrete foundations.
It will be observed the lower portion H of each block is of a narrower section than
the upper portion, thus allowing a free space as shewn, for the mastic composition to
enter as far as the metal tongue.
Figure 2 represents a perspective view of a design of flooring, the narrow lines A
as in Figure 1 being the grooves, which are cut both lengthways and crossways of
the blocks.
Figure 3 represents a plan of one form of design of wood block flooring, the
dotted lines B being the metal tongues.
Figure 4 is a plan of Figure 2 the dotted lines B representing the metal tongues.
My improvements are applicable to any design of wood block flooring.
I am aware that various methods have from time to time been tried of securing
wood block together, by means of small plugs or dowels, inserted in each end of the

page_text: Block, and again I am aware of such blocks being secured together, by wooden
tongues, inserted in grooves, therefore I do not propose to claim such longitudinal
grooving, or the principle of tongue fastening as being novel, but what I do claim is
1st. In wood block flooring, metal tongues inserted in recesses or grooves substan-
tially as and for the purposes herein described.
2ndly. The construction, combination and general arrangement of the Wood Blocks,
with the metal tongues, together with the mastic composition, forming a firmly
bonded, wood block flooring, substantially as herein described.
