IMPROVEMENTS IN WOODEN PAVEMENT be as
Year: 1884

page_text: I JOHN MCGRIGOR CROFT of N° 15 Abbey Road, St John's Wood, in the
County of Middlesex, Physician, do hereby declare the nature of the said invention
for "IMPROVEMENTS IN WOODEN PAVEMENT to be as follows:-
"
My invention relates to the paving with wooden blocks of roads, alleys, paths or
other ways or spaces, and has for object to produce a wooden pavement that will
keep comparatively dry and will not be liable to get out of shape as is the case
with wooden pavement of the ordinary descriptions heretofore usually employed.
For this purpose I form in the lower portions of the wooden paving blocks
grooves or channels, and I lay these grooved or channeled blocks in rows transverse
to the road or way, so that the groove or channel of one block aligns with those of
the blocks adjoining it. Thus there is formed across the road or way under the
wooden blocks and between them and the asphalt, concrete, or other surface
whereon they rest, a series of channels or passages. At the sides of the
road or way blocks are laid having in them grooves or channels arranged
lengthwise of the road or way, and the transverse channels or passages are
connected with these longitudinal channels or passages so that water can flow
by the transverse into the longitudinal channels or passages, and thence to gulleys
or drains.
By my invention the pavement being kept comparatively dry will not be liable
to rot, will be more pleasant to travel upon, and will afford a better foot-hold to
draught animals than is the case with ordinary wooden pavement.

page_text: I, JOHN M°GRIGOR CROFT, of N° 15 Abbey Road, St John's Wood, in the
County of Middlesex, Physician, do hereby declare the nature of my invention
for "IMPROVEMENTS IN WOODEN PAVEMENT" 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 the paving with wooden blocks of roads, alleys, paths
or other ways or spaces, and has for object to produce a wooden pavement that
will keep comparatively dry and will not be liable to get out of shape as is
the case with wooden pavement of the ordinary descriptions heretofore usually
employed.
For this purpose I form in the lower portions of the wooden paving blocks,
grooves or channels, and I lay these grooved or channeled blocks in rows transverse
to the road or way, so that the groove or channel of one block aligns with those of
the blocks adjoining it. Thus there is formed across the road or way under the
wooden blocks and between them and the asphalt, concrete, or other surface whereon
they rest, a series of channels or passages.
At the sides of the road or way blocks are laid having in them grooves or channels
arranged lengthwise of the road or way, and the transverse channels or passages
are connected with these longitudinal channels or passages so that water can flow
by the transverse into the longitudinal channels or passages, and thence to gullies
or drains.
By my invention the pavement being kept comparatively dry will not be liable
to rot, will be more pleasant to travel upon, and will afford a better foot-hold to
draught animals than is the case with ordinary wooden pavement.
In the accompanying sheet of illustrative drawings Fig 1 is a plan or top view
of three transverse wooden paving blocks, and Fig 2 is an end view of the same.
Fig 3 is a plan or top view of one of my improved longitudinal wooden paving
blocks with portions of three adjacent transverse blocks and Fig 4 is a vertical
section of the same in the line x. x. Fig 5 is a plan or top view to a smaller scale
of a portion of a road or way showing the manner in which my improved
paving blocks are arranged. a. a. are wooden paving blocks which may be of
the ordinary form but each of which is provided at its lower surface with a
groove, channel or passage b which may be of any desired cross sectional
form. These blocks which I term transverse paving blocks are arranged in rows
transverse to the road or way upon which they are laid, and in such manner that
the groove or channel b of all the blocks in each row shall be in line as shown in
Fig 5.
c. c. are wooden paving blocks which may also be of ordinary form but
each of which is provided at one side of its lower surface with a longitudinal
groove, channel, or passage d. These blocks e which I call longitudinal paving
blocks are arranged longitudinally and at cach side of the road or way in such
manner with relation to the blocks a that the grooves channels or passages b are in
communication with the grooves channels or passages d as clearly shown in Figs 3,
4, and 5. e is an asphalt, concrete, or other bed or road upon which the blocks
are laid, and f the grid of a gulley or trap in connection with the drains. It will
thus be evident that any water which may find its way between the paving blocks
and the bed upon which they rest, can readily flow by the transverse grooves,
channels or passages, into the longitudinal grooves, channels, or passages and
thence to the gulley and drains. It will be readily understood that I may employ

page_text: grooves channels or passages of various forms in transverse section; also that each
block may have more than one channel or passage in it.
By my invention as above stated the pavement being kept comparatively dry
will not be liable to rot; it will be more pleasant to travel upon than wooden
pavement as heretofore usually constructed and will afford a better foothold to
draught animals than is the case with ordinary wooden pavement. Roads or ways
constructed as above are also comparatively noiseless.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The use of transverse blocks with grooved or channelled under surfaces as
described.
2. The use of longitudinal blocks with grooved or channelled under surfaces as
described.
3. The improved wooden pavement comprising transverse grooved or channelled
blocks and longitudinal grooved or channelled blocks arranged substantially as and
for the purposes above set forth and illustrated by the drawings.
