I JOSEPH WHITELEY of Clowes Street Works Chapel Street Salford. in the
County of Lancaster General Pattern Maker do hereby declare the nature of my
Invention for IMPROVEMENTS IN AND MACHINERY FOR THE MANUFACTURE OF
DOOR AND OTHER MATS, TREADS OF STAIRCASES FLOORING AND OTHER SIMILAR
WEARING SURFACES to be as follows:-
The object of this invention is to construct mats, treads of staircases flooring
and other similar wearing and rubbing surfaces by a combination of metal and
india-rubber or other suitable elastic or wearing material whereby a cheaper
wearing surface than and possessing all the properties of the india-rubber mats now
in use can be produced. .
In carrying out my invention. I employ a grating of malleable cast iron, cast
iron brass or other suitable metal and I fill in the perforations with india-rubber
blocks for which purpose the waste india-rubber punchings. produced in the.
manufacture of ordinary india-rubber mats may be utilized.
These india-rubber blocks are forced into position by means of a suitable press
consisting of a thin metal hopper into which the block is first introduced and then.
by means of screw or other pressure is forced through into the perforation in the
metal grating below and thus is secured in position but so as to project a suitable
distance on each side the grating to serve as the wearing surface The india-rubber.
may project more or less over the surface of the grating so as to give a better
rubbing action. The grating which is capable of being made of any design can
also be jointed dovetailed or laid together in sections and may be screwed down if
required.
こ
As a modification of my invention I also take india-rubber strips and bind them
in parallel rows by inserting between them intervening pieces of wood or other
material suitably grooved for the purpose and screwing the whole together-the
india-rubber strips in this case project above the wood and thus constitute the
wearing surface or I take suitable forms of india-rubber wooden or other blocks
and weave the same together by wirework for which purpose I prefer to have
grooves surrounding the blocks to receive the wires and in some cases I employ
continuous lengths of india-rubber and after weaving them together by wires, I cut.
off the india-rubber to the desired thickness or length to form the mat or other.

COMPLETE SPECIFICATION.
I, JOSEPH WHITELEY, of Clowes Street Works, Chapel-Street; Salford, in the
County of Lancaster, General Pattern Maker, do hereby declare the nature of my
said Invention for "IMPROVEMENTS IN AND MACHINERY FOR THE MANUFACTURE
OF DOOR AND OTHER MATS TREADS OF STAIRCASES, FLOORING AND OTHER SIMILAR
WEARING SURFACES," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The object of this invention is to construct mats, treads of staircases, flooring
and other similar rubbing and wearing surfaces by a combination of metal and
india-rubber or other suitable elastic or wearing material whereby a cheaper
wearing surface than and possessing all the properties of the india-rubber mats now
in use can be produced. On the accompanying drawing Fig 1 represents a plan
view and Fig 2 a sectional view of my improved mat or wearing surface of
combined metal and india-rubber or other similar elastic material.
In carrying out my invention I employ a grating (a) of malleable cast iron,
cast-iron, brass or other suitable metal as seen separartely in sectional view
Fig. 3, and in which grating perforations or holes bare cast or otherwise formed
I fill in these perforations, or holes with solid-india-rubber blocks c and for which
purpose the waste india-rubber punchings or cuttings produced in the manufacture
of ordinary india-rubber mats can be utilised the solid india-rubber blocks being
forced into position in the perforations by means of a suitable press consisting of a
thin metal hopper into which the india-rubber block is first introduced and then
by means of screws or other pressure is forced through into the perforation in the
metal grating below and thus is secured in position but so as to project a suitable
distance on one or both sides of the grating to serve as the wearing surface.
The india-rubber may project more or less over the surface of the grating so as
to give a better rubbing action.
+
The grating which it is apparent is capable of being made of any design and
with various forms of perforation can also be jointed dovetailed, or laid together in
sections and may be screwed down if required.
I also take india-rubber strips d as seen in plan view Fig. 4 and side view Fig. 5
and bind them in parallel rows by inserting between them intervening pieces of
wood or other suitable material e suitably grooved and undercut for the purpose
and screwing the whole together by screws f passing transversely through the
whole and having screw nuts g at one or both extremities. The india-rubber strips
in this case project above the wood or other material as illustrated and thus
constitute the wearing surface; or metallic rods or tubes g may constitute the
intervening material as seen in plan view Fig. 6 and side sectional view Fig. 7
such rods or tubes being all braced together by screws passing transversely through
the whole as in Figs 4 and 5, or secured together at the ends by screws h passing
through the metallic edge pieces or borders i.

page_text: I wish it to be understood that I do not confine myself to the shape or section
of the intervening pieces-nor to the shape or section of the india-rubber strips.
provided that the same are inserted in grooves or otherwise as herein before
described and illustrated on the accompanying drawing as the same may be con-
siderably varied without departing from my invention-nor do I confine myself to
using india-rubber strips-as strips of other suitable material may be substituted
as the wearing surface. Further I wish it to be understood that I do not claim
binding strips of india-rubber together without the use of the grooves in the
intervening pieces of wood or other material as I am aware that this has before
been attempted and involves wider strips of india-rubber and hence is more
expensive.
In some cases for the sake of portability I hinge the intervening pieces or suitable
sections of the mat or flooring together and thus am enabled to roll up the surface
into small compass and in this case the screws which secure the hinges in position
can be utilised for binding the adjoining intervening pieces together and so as to
grasp the india-rubber strip between them.
Having thus particularly described and ascertained the nature of my invention
I declare that what I claim is
1st The improved manufacture of door or other mats, treads of staircases, flooring
and other similar wearing surfaces substantially as herein before described.
2nd The improved combination of perforated metal plates or gratings and india-
rubber blocks and modes of introducing and securing the same together sub-
stantially as and for the purpose herein before described and illustrated on the
accompanying drawing.
3rd The improved combination of parallel strips of india-rubber or other
suitable material bound together and supported in parallel rows in suitable grooves
formed in intervening pieces of wood or other suitable material substantially as
and for the purpose herein before described and illustrated on the accompanying
drawing.
