Lancashire do hereby declare the nature of my invention for IMPROVED TREADS TO
STAIRCASES PASSAGES AND THE LIKE to be as follows:-
Formed of Grids or perforated panels to be composed of a framework of iron or
other material, divided on plan into openings, of any shape or configuration found
most suitable, these openings are to be filled in with leather India rubber or other
suitable material or materials, having on their under side a collar, rim or flange, or
projection, to secure or key them in their positions, so as to prevent their coming
out of the holes or openings, in order to effect this the frame work of Grid or panel
on the under side of opening, will have to be rebated, or reduced, so as to form a
space or recepticle, to allow of this collar flange or rim The pieces filling openings
may have the flanges repeated at the top or upper surface of grid so as to prevent
their either being pushed through same or pulled out The pieces of leather, India
rubber or other material may either be in one piece or built up of two or more
pieces cemented and riveted or screwed together so as to form one solid mass.
The great novelty claimed in this invention is that the pieces of leather or other
materials are movable and interchangable so that the worn parts may be replaced
by those that are not worn and though movable when grid is screwed or otherwise
secured in position they are securely held in position by flanges rims or collars, on
each respective piece of leather India rubber or other material.

TO STAIRCASES, PASSAGES, AND THE LIKE and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
To be formed of Grids or perforated panels to be composed of a framework of
iron or other material divided on plan into openings of any shape or configuration
found most suitable, these openings are to be filled in with leather India-rubber or
other suitable material or materials having on their under side a collar, rim flange
or projection, to secure, or key them in their positions so as to prevent their
coming out of the holes or openings, in order to effect this the frame work of Grid
or panel on the under side of openings will have to be rebated or reduced so as to
form a space or recepticle to allow of this collar flange rim or projection The picces
of leather India-rubber or other material may either be in one piece or built up of
two or more pieces cemented and riveted or screwed together so as to form one solid
On drawings the frame or Grid of iron or other material is marked A and
the India-rubber Leather or other material is marked B. the Grid or framework
having rebates or recesses and the India-rubber or other material Collars or
projections of the form shewn or indicated on drawings.
mass
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
1st The rubber or other material is held in position in Grid by a distinct rebate
or recess of form shewn on Drawings.
2nd That each piece of rubber or other material has a distinct collar or flange
to secure it in position and that each piece of rubber or other material is inter-
changeable and easily removed without injury to same.
3rd The pieces of rubber or other materials are held in position in grid by
securing it to step or floor with screws or other fastenings.
4th The rubbers or other materials to have flutings or projections on their upper
surface so as to provide a more secure foothold to those treading or walking on
same.
