Improvements in Wood Pavements.
I JOHN CLARk Jefferson, of 2 East Parade Leeds in the County of York
Patent Agent do hereby declare the nature of this invention to be as follows :-
My invention relates to improvements in wood pavements, and has for its
purpose to obviate the disadvantages attendant on the use of wood as at present,
for instance to prevent cracking of the surface due to the changing effect of sun and
rain.
For this purpose I provide each wood block with a metal ring, which holds the
block firmly in its place, and prevents swelling of the wood from moisture. These
rings may be rectangular, diamond shaped, or polygonal in plan, and the wood
blocks are shaped to correspond; and driven tightly each within the ring which
encloses it for the full depth on all sides.
Dated this 30th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Wood Pavements.
I JOHN CLARK JEFFERSON of 2 East Parade Leeds in the County of York,
Patent Agent 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 relates to improvements in wood pavements, and has for its
object to obviate the disadvantages attendant on the use of wood as at present;
for instance to prevent cracking of the surface due to the changing effect of sun
and rain.
For this purpose I provide each wood block with a metal ring, which holds the
block firmly in position and prevents excessive swelling of the wood from
moisture.
- These metal rings may be rectangular, diamond shaped, circular, or polygonal in
plan, and the wood blocks are shaped to correspond and driven tightly each within
its ring, which encloses the block for the full depth on all sides. -
And in order that my invention and the manner in which the same is to be
performed may be more readily and clearly understood, reference is given to the
accompanying drawings and to the letters and marks thereon.
Fig. is a side view of a wood block provided with a rectangular ring of
metal.
Fig. 2 is a cross section on line A B Fig. 3, which latter is a plan of the upper
(or under) surface of the block.
Fig. 4 is the profile of an iron support, which can be used in connection with the
pavement, but which not being part of the invention, is not further described.
a a is the wood block.
bb is the metal ring.
I prefer to make the blocks and rings hexagonal in plan, as I find this the most
convenient and effective shape.
The advantages of my invention are:-That the blocks are prevented from

page_text: having their surface rounded off; the wear and tear is more or less evenly
distributed over the surface of the pavement; as the rings enclose the blocks, (thus
preventing them from splitting), blocks with a core can be used, which considerably
diminishes the cost; and the metal rings serve as foot holds for the horses.
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 :-
:-
In the construction of wood pavements the use of wood blocks rectangular,
circular, or polygonal in plan, enclosed by corresponding rectangular, circular, or
polygonal metal rings, substantially as herein set forth.
