Improvements in Concrete Paving and the like.

page_text: Improvements in Concrete Paving and the like.
We, DAVID BURNESS and JAMES BURNESS, Plasterers and Cement Workers, both
of 19, Murray Lane, Montrose, N.B., do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in connection with paving stairs, railway
platforms and the like in which concrete is employed, and has for its object to
provide an arrangement which will prevent the danger of slipping on the concrete
surface.
In carrying out our invention we propose to form the concrete with a number of.
holes or recesses placed at suitable distances apart. These recesses are preferably
screw threaded and into them I propose to screw a plug of hardened rubber or
similar material. The plug is also screw threaded to correspond with the recess
so that it can be fixed firmly in place. The plug may be notched or grooved at
the top to allow it to be inserted by means of a screw driver. When the rubber is
worn level with the cement, it can be given a half turn raising it slightly above
the adjacent surface, thus allowing the rubber to be effective until completely
worn out. The number of rubber screws employed will depend upon the traffic
all the recesses being provided with plugs or a portion only. When completely
worn out fresh plugs can be easily inserted in place, any danger of slipping on the
concrete surface is thus obviated.

Improvements in Concrete Paving and the like.
We, DAVID BURNESS and JAMES BURNESS, Plasterers and Cement Workers, both
of 19, Murray Lane, Montrose, N.B., 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 improvements in connection with paving stairs, railway
platforms, and the like in which concrete, stone or other similar substance is
employed and has for its object to prevent the liability or danger of slipping on
the said concrete or other smooth or polished surface.
In carrying out our invention we propose to form the concrete or stone surface
with a number of holes or recesses arranged at suitable distances apart.

page_text: These holes or recesses are preferably formed with internal screw threads and
into each of the same is screwed a plug of hardened india-rubber or other similar
resilient material. The plug is formed with a male screw thread for this purpose
corresponding with the thread in the hole or recess so that it can be fixed firmly
in place and in order to facilitate the screwing in of the plug it may be formed
with a notch or recess at the top for the insertion of a screw driver.
When the plug is worn below or level with the concrete or other surface it may
be given a half turn so as to raise it slightly above the said surface, thus per-
mitting the effective use of the plug until completely worn out.
The number of screwed plugs employed will depend upon the traffic and when
they are completely worn out fresh ones can be easily inserted in their place.
And in order to clearly understand the invention, reference is made to the
accompanying sheet of drawings in which Fig. 1 is a section of a portion of a con-
crete paving block with two plugs screwed therein and Fig. 2 is a plan of a step
or other block fitted with the improved non-slipping plugs.
a is the concrete or other block formed with the screw holes or recesses a³ into
which the india-rubber or other screw-threaded plugs 6 are inserted by means of
a screw driver engaging with the notch or recess 71 at the top of the plug.
When the upper or wearing surface of the plug is worn away it may be screwed
up so as to project slightly above the surface a as shown to the right in Fig. 1 and
the said plugs may be arranged on a block or step as shown in plan in Fig. 2 or
in any other suitable manner and more or less in number according to circum-
stances.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
-
(1) In concrete or the like paving and other surfaces providing the same with
holes or recesses formed with internal screw-threads for receiving and holding
screw threaded plugs of hardened india-rubber or other resilient material, sub-
stantially as described and for the purposes specified.
(2) In concrete or similar paving the combination therewith of hardened india-
rubber plugs such as 6 inserted or screwed into holes or recesses in the said paving
substantially as described and for the purposes specified.
(3) The improvements in concrete paving and the like, substantially as described
and shown in the accompanying sheet of drawings.
