Complete Specification Left, 2nd Mar.. 1897-Accepted, 3rd Apr., 1897
Appliance for Preventing Cats and other Animals from Climbing
Over or Passing Along Walls and the like.
I, JOHN CAMERON GRANT, of Albert Lodge Albert Place, Kensington, in the
County of London, Engineer, do hereby declare the nature of this invention to be
as follows:-
According to my invention I effectually prevent cats and other animals from
climbing over or passing along walls and the like, by fixing upon the top of the
wall a strip of zinc or other suitable metal, preferably of about the same width as
the wall, the upper surface of which strip is provided with upward projecting sharp
points arranged so close together that a cat cannot get its paws between them.
The said sharp points may be produced either by driving pins or tacks through
the back of the sheet of zinc, or by raising sharp points by punching out of the
sheet metal itself.
Instead of making the strips with points of the full width required, they may be
made quite narrow, so as to contain only one, two or more rows of points, any
number of such strips being then fixed closely side by side on a suitable-
foundation.
The said strips can be secured to the wall either by simply passing wires across
the strip, the end of the wires being secured to nails on each side of the wall, or
the strips can have wire or other loops or eyes attached to each edge thereof, which
loops are secured to the wall by nails.

Appliance for Preventing Cats and other Animals from Climbing
Over or Passing Along Walls and the like.
I, JOHN CAMERON GRANT, of Albert Lodge, Albert Place, Kensington in the
County of Middlesex, 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 :-
According to my invention I effectually prevent cats and other animals from
climbing over or passing along walls and the like, by fixing upon the top of the
wall a strip of zinc or other suitable metal, preferably of about the same width as
the wall, the upper surface of which strip is provided with upward projecting
sharp points arranged so close together that a cat cannot get its paws between
them.
The said sharp points are produced by raising sharp points punched out of the
sheet metal itself.

page_text: Instead of making the strips with points of the full width required, they may be
made quite narrow, so as to contain only one, two or more rows of points, any
number of such strips being then fixed closely side by side on a suitable foundation,
or they may be used singly for fixing on rails, copings, and the like, for preventing
birds from alighting. Such narrow strips may also be twisted and used in lieu of
barbed wire.
The said strips can be secured to walls either by simply passing wires across the
strip, the end of the wires being secured to nails on each side of the wall, or the
strips can have wire or other loops or eyes attached to each edge thereof, which
loops are secured to the wall by nails.
Figure 1 of the accompanying drawing shews a plan of part of a sheet of metal
having sharp points raised thereon by punching, for the purposes of my said
invention; Figure 2 shews an end view, and Figure 3 shews a section on
line XX Figure 1. The triangular pieces a a are formed by two angular cuts
preduced by suitable punches so as to present a sharp apex, and they are bent up
at right angles to the plate; they are arranged at such a distance apart that on
the one hand a cat or other animal cannot introduce its paw between the points,
and on the other hand that the paw shall only rest on a few of the points, in order
that they may have an effective pricking action.
Such plate may be cut into narrow strips of any width, for fixing on rails,
copings &c., or the strips may be twisted as at Figure 4, and serve in lieu of barbed
wire. Or narrow strips of metal may have the points a punched closer together
therein as at Figure 5, for preventing birds from alighting on fence rails,
copings &c.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is :-
An appliance for preventing animals from passing over or resting on walls, rails,
copings and the like, consisting of a sheet or strip of zinc or other suitable metal,
in which are formed sharp angular incisions, the cut parts being bent up so as to
present sharp points, substantially as described.
