SHEET METAL FABRIC
Year: 1884

page_text: COMPLETE SPECIFICATION,
I, ISRAEL KINNEY; of the Town of Windsor, in the Province of Ontario, in the
Dominion of Canada; Machinist; do hereby declare the nature of my invention
for "SHEET METAL FABRIC," 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 a new and useful Sheet Metal Fabric, used for panels
in fencing, counter railing &c.
The manufacture of this fabric will be particularly described with reference to
the accompanying drawings wherein
Fig. 1. shows a flat sheet of metal slitted.
Fig. 2. shows an edge view of the slitted sheet of metal corrugated.
Fig. 3. is a front view of the sheet metal fabric showing the strips bent around
and their adjacent faces resting against each other.
Fig. 4. is a view of this sheet metal fabric with the strips partly bent around.
Fig. 5. shows a plan view of a column or tube constructed from this fabric.
Fig. 6. is a sheet of metal slitted in which the strips between the slits are
tapering towards a given point.
Fig. 7. shows an edge view of a sheet of metal in which corrugations of different
depths are formed.
Fig. 8. is a sheet of metal slitted, in which the strips between the slits vary in
width towards one edge.
Fig. 9. is a top view of a fabric (constructed from the sheet of metal shown in
Fig. 8.) which is heavier and stronger at the point where the strips are the widest.
A, is a sheet of metal provided with the slits B, B, and corrugations C, C, as
shown in annexed drawings.
The strips D, D, formed by these slits B, B, are partly bent around as shown in
Fig. 4. of annexed drawings, or these strips may be bent completely around so that
their adjacent faces rest against each other and form the fabric shown in Fig. 3. of
annexed drawings, forming openings H, H, of any suitable size or shape.
These slits may be formed in the metallic sheet A, at an angular or horizontal
position to the edges of the sheet of metal A, and may be curved, straight or any
form desired; and the faces of these strips may be corrugated or embossed to
ornament and stiffen them, when constructed of very thin material.
Instead of these slits B, B, in the sheet of metal A, a portion of said sheet of
metal may be removed, and openings B³, of any suitable size or shape may be
formed in said sheet of metal A.

After this fabric is formed it may be galvanized or tinned to protect the edges
as well as the body of the metal from corrosion and also to unite and hold the
adjacent faces of the strips D, D, together when constructed in this manner.
The feet or steps E, E, integral with the strips D, D, either at the upper or
lower end or both may be bent in any suitable form by which said fabric may be
attached to a framework,
F, is a rail or other suitable device placed at the top or in any desired position
to stiffen said fabric.
It is evident that this fabric when completed or when in the course of completion
may be expanded, contracted or bent in many different shapes to form various
articles of trade.
I would have it understood that I do not wish to confine myself to this par-
ticular construction or manner of constructing. the fabric, as other forms and ways
may be used without departing from the spirit of my invention, as it is evident
from the foregoing, that I contemplate forming suitable openings in ordinary sheet
metal, without punching out or wasting but little, if any, of said metal, at the
same time placing the edges of the metal at an angle to the face of the fabric so
that great strength and stiffness is obtained; and the area of the fabric in many
cases considerably enlarged to that of the original sheet.
In Fig. 6. of annexed drawings is shown a modification of Fig. 1. in which the
strips are formed in the sheet of metal tapering towards a given point so that when
these strips are distorted from their original position either in a fabric or column,
the fabric or column will be strongest and heaviest at the point formed by the
strips of the greatest width. .
These strips D, D, are provided with barbs G, G, as shown in Fig. 3. of annexed
drawings and when a number of these strips are combined together to form a
fabric or column, this fabric or column. is barbed to more effectually keep off
intruders.
And these strips D, D, may be provided with corrugations C¹, C¹, formed at
different depths in said strips D, D, as shown in Fig. 7. of annexed drawings, so
that when the strips are slitted and distorted from their original position the
fabric or column will expand or contract according to the depth of the corrugations.
It is immaterial in the construction of this fabric, whether the slits are formed in
the sheet of metal before or after the forming of the corrugations.
As shown in Fig. 8. of annexed drawings, the sheet of metal is slitted, and the
strips between the slits vary in widtli towards one edge, but they may vary in
width towards one or both edges, so that when corrugated and formed into a
fabric, the fabric will be heavier and stronger at the point where the strips are
the widest, and is especially adapted for panels requiring greater strength in the
centre or at one edge, such as for fence panels or gates.
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 An open and stiffened sheet of metal formed by slitting the sheet as
described, and then bending the strips between the said slits, out of the plane
which they occupied in the original sheet, substantially as and for the purpose set
forth.
2nd A sheet of metal slitted and fashioned as described, galvanized or tinned
after the metal is cut and put into shape as set forth, for the purpose specified.
3rd A Metallic Fabric constructed as described, and provided with feet, steps or
projections E, E, integral therewith substantially as shown and described and for
the purpose specified.
4th A tube or column constructed from a sheet of metal slitted, and the strips
between the slits distorted from their original position in the sheet to form
openings, substantially as described,

page_text: 5th The combination of the sheet metal fabric, constructed as described, with
a rail or other suitable device placed on the top or in any desired position to stiffen
said fabric substantially as described.
6th A. fabric or column constructed from a sheet of metal slitted, in which the
strips between the slits are cut tapering towards a given point, so that when these
strips are distorted from their original position, the fabric or column will be
strongest and heaviest at the point formed by the strips of the greatest width,
substantially as set forth.
7th A fabric or column constructed from a sheet of metal slitted, and the strips
between the slits provided with barbs substantially as shown and described.
8th A fabric or column constructed from a sheet of metal slitted, and corrugated,
the corrugations in which are formed at different depths, so that when the strips
between the slits are distorted from their original position the fabric or column
will expand or contract according to the depth of the corrugations, substantially as
and for the purpose specified.
9th A fabric constructed from a sheet of metal in which the strips between the
slits vary in size towards one or both edges, substantially as shown and described.
Dated this 9th day of Sentember A.D. 1884.
