An Improvement applicable to Ladders.
I, WILLIAM THOMSON, of Wellfield Iron Works, Rochdale, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement on an invention for which I made
application for Letters Patent with a Complete Specification and drawings on the
26th day of January 1899, No. 1821, which invention consisted in the combina-
tion of a metal shoe and pad of india rubber, or other soft compressible substance,
to be applied to the lower end of the side rails of a ladder to prevent slipping
substantially as described and illustrated by the said specification and drawings;
according to which invention the ladder must always be placed with one particular
side leaning against the wall otherwise the anti-slipping shoe would be inoperative,
but the object of the present invention is so to form and adapt the shoe that the
ladder may be turned over with either of its sides towards the wall and the shoe
will be equally effective.
For this purpose I bevil off the foot of each side rail of the ladder in both
directions so as to form an obtuse angled V and I make the metal bracket or shoe
with a double or V-flange to correspond, each wing of the flange having an elon-
gated hole to receive a flanged rubber pad which is held in place in the same
manner as before.
It will be seen that this new form of anti-slipping shoe will be equally operative
whichever side of the ladder may be placed against the wall.

An Improvement applicable to Ladders,
I, WILLIAM THOMSON, of Wellfield Iron Works, Rochdale, in the County of
Lancaster, Engineer, 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 an improvement on the invention described in the
specification of the patent granted to me numbered 1821 dated January 26th
1899, for an improvement applicable to ladders. The object of this present inven-
tion is to enable my improvement to be applied to ladders so that when either

page_text: side of a ladder may be outwards the foot of the ladder which rests upon the
ground is prevented from slipping. In the accompanying drawing Fig. 1 is an
elevation, and Fig. 2 an edge view showing the dual metal shoe and non-slipping
pads for attachment to the foot of each side rail of the ladder as shown in Fig. 3.
For the purpose of this invention I bevil the foot of each side rail of the ladder
in both directions so as to produce a V-shaped end as a¹ and I make the metal
bracket or shoe correspondently V shaped to fit thereon, with two wings or
flanges and 2, in each of which is an elongated hole to receive a flanged rubber
or other non-slipping pad e, which is held in its place in the manner described in
the specification of the patent herein-before named.
By these means the ladder may be turned over with either of its sides towards
the wall and the shoe will be equally effective.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
The combination of a dual metal shoe and pads of india rubber or compressible
substance to be applied to the bottom end of each side rail of a ladder to prevent
slipping substantially as herein before described and illustrated in the accom-
panying drawings.
