Improvements in and in the Manufacture of Shelf and like
Supporting Brackets.
:-
I, ARTHUR THORP MATCHETT of 21 George Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention has relation to shelf and other like supporting brackets, and
consists in a sheet or wrought metal article.
By my improvements, such brackets are light in weight and are endowed with a
maximum of strength.
According to one form of my invention, in connection with a shelf bracket I
make the same from a fashioned T-sectioned strip of steel, with the web at vertex
of the angle of the bracket to be made, mitre gapped, so that when the sectioned
metal is beut at the angle-point, to form an angle bracket, the opposed edges of
the mitre come together and form a butt joint.
The top or crossing web may be pierced with holes, for the passing therethrough
of screws or the like for the affixing of the bracket to a wall and the shelf to the
bracket.
A tie or stay in the form of a curved or angular strip is connected to the webs
of the angle by ears, which overlap the said webs, and are secured by rivetting or
otherwise, whilst inward and adjacent to the ears, are gaps, with one side cut to
the plane of the under edge of the web, so as to make a butt joint for an additional
support.
In carrying out the manufacture of the bracket, I take a strip of thin sheet
steel and fold the same longitudinally about its middle and partly upon itself, and
with the unfolded parts turned at right angles, there is thus formed a T-sectioned
bar with the cross web of single thickness of metal and the leg or inner web of a
double thickness.
A sufficient length of metal to form a bracket is then taken and a V gap at an
angle of 45 degrees is then made in the web of double thicknesses. Then the
length is bent to a right angle, until the opposed edges of the gap abut, and form
a joint at the vertex of the angle. This joint may be plain or it may have
inserted within parts of the opposed ends a short angle tie.
The bracing tie which is directed from the one web to the other and is secured
by rivetting, is either made out of two strips placed face to face, and the ears
slightly cranked, so as to form embracing lugs, or the said ears may lie in the
same plane as the face of the strips. This tie which braces the inside corner of
the bracket may be made of a double thickness by folding a strip of metal upon
itself.
Instead of making the bracket from thin sheet steel or other suitable metal it
may be made from a T-sectioned solid bar and gapped to allow the bending at the
angle.
The stays may be longitudinally corrugated so as to increase the strength of the
article.
Instead of making the bracket from T sectioned metal, the same may be made
from I or H section metal. The webs of single thickness of metal may be rolled
into hollow beadings, in which wire or like metal for strengthening the parts may
be inserted.

page_text: For strong brackets I may employ double inside webs, separated from each
other by a space.
The gapping to form the mitre may be performed when the metal is in the flat,
before the same is fabricated into the desired section, which may be accomplished
by rolling or drawing, or part rolling and drawing and partly by press tools.
As a still further form I may make the edging of the under web, hollow
beaded.
The application of my invention to other solid fabricated brackets, differs in no
essential respect to that of a shelf as described.

Improvements in and in the Manufacture of Shelf and like
Supporting Brackets.
I, ARTHUR THORP. MATCHETT, of 21 George Street, in the City of Birmingham,
Manufacturer, 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 has relation to shelf and other like supporting brackets, and
consists in a sheet or wrought metal article.
By my improvements, such brackets are light in weight and are endowed with
a maximum of strength.
According to one form of my invention, in connection with a shelf bracket, I
make the same from a fashioned T-sectioned strip of steel, with the web at the
angle, or at the vertex of the angle of the bracket to be made, mitre-gapped, so
that when the sectioned metal is bent at the angle point to join an angle bracket,
the opposed edges of the mitre come together and make a butt joint.
The top or crossing web may be pierced with holes for the passing therethrough
of screws or the like for the affixing of the bracket to a wall and the shelf to the
bracket.
A tie or stay in the form of a curved or angular strip is connected to the webs
of the angle by ears, which overlap the said webs, and are secured by rivetting or
otherwise, whilst inward and adjacent to the ears at the ends of the said stay are
shoulders directed in the plane of the under edge of the web, and constituting
abutments or additional supports.
In carrying out the manufacture of the bracket I take a strip of thin sheet steel
and fold the same longitudinally about its middle and partly upon itself, and with
the unfolded parts turned at right angles. There is thus formed a T-sectioned
bar with the cross web of a single thickness of metal and the leg or inner web of
a double thickness.
A sufficient length of metal to form a bracket is then taken and a V gap with
the sides of an angle of 45 degrees is made in the web of double thickness. Then
the length is bent to a right angle and until the opposed edges of the gap abut
and form a joint at the vertex of the angle. This joint may be plain or it may
have inserted within parts of the opposed ends a short angle tie.
The bracing tie which is directed from the inner web of one leg of the bracket
to the like web of the other and is secured by rivetting, is either made out of two
strips placed face to face and the ears slightly cranked so as to form embracing
lugs, or the said ears may lie in the same plane as the face of the strips. This tie,

page_text: which braces the inside corner of the bracket, may be made of a double thickness
by folding a strip of metal upon itself.
Instead of making the bracket from thin sheet steel or other suitable metal it
may be made from a T-sectioned solid bar gapped at a suitable part to allow for
the bending at the angle.
The stays may be longitudinally corrugated so as to increase the strength of the
article made.
Instead of making the bracket from T sectioned metal, the same may be made
from I or H section metal. The webs of single thickness may be rolled into hollow
beadings, in which wire or like metal for strengthening the parts, may be inserted..
For strong brackets I may employ double inside webs, separated from each other
by a space.
The gapping to form the mitre may be performed when the metal is in the flat,
before the same is fabricated into the desired section, which may be accomplished.
by rolling or drawing, or part rolling and drawing and partly by press tools.
As a still further form I may make the edging of the under web, hollow
beaded.
Figure 1 of the accompanying drawings represents a shelf or like bracket made
and constructed according to one form of my improvements.
The bracket consists of two lengths of T-sectioned metal, each having a double
vertical web a, and a horizontal web b, with the webs a, abutting at a', which
abutment is allowed by the cutting out of a mitre gap as hereinafter described.
c is an angle stay or bracket connected by ears c', to both the inner double
webs a, and being there affixed by rivetting at c².
In carrying out the manufacture of the said bracket Figure 1, I take a length
of thin strip steel or other metal Figure 2, and bend the same into a T-shaped
cross section shown in underside plan in Figure 3, side elevation in Figure 4, and
topside plan in Figure 5, and having a double web a, and single webs b. Then by
gapping or cutting-out tools, I mitre a middle part of the double web at a², and if:
necessary shape the end at a³, as represented in underside plan and side elevation
in Figures 6 and 7, Figure 8 being a cross section of Figure 6 upon the dotted
line x.
Figure 9 represents the bent bracket without the stay and Figure 10 is a
perspective view, upon an enlarged scale, of the T-section length of metal from.
which the bracket is fashioned.
In carrying out another method of making the said bracket Figure 1, I take a
pierced and fashioned blank of strip metal Figure 11, having a piercing a*, and
fashioned ends a, and fold the same up into a T section, as represented in under-.
side plan in Figure 12, topside plan in Figure 13, side elevation in Figure 14 and
section in Figure 15. Figure 16 represents the bracket formed from the said
strip Figures 12, 13, 14 and 15.
Figure 17 represents a bracket constructed according to a further form of my
invention in which a, a are the inner webs, with the abutting edges a', of the
cut-out mitre meeting at a² and with the sides of the bracket united by a stay c,
whose cared ends c³, pass through holes a, in the underside edges of the webs a,
and being there secured either by closing the metal of the sides upon the said ears
or by rivetting the same together at c.
Figure 18 represents a further modified form of bracket and Figure 19 is a
section of the same upon an enlarged scale upon the dotted line Figure 18.
In carrying out the manufacture of this form of bracket, I take a pierced and
fashioned blank Figure 20 and bend the same up into a T-shaped section, as
represented in underside plan and side elevation in Figures 21 and 22 and then by
folding the said T section length upon the dotted lines ³, Figure 21, into a right
angle, the edges a', as upon each side respectively abut against solid parts of the
single thickness webs of the bracket.
Figure 23 represents a further form of bracket provided with an insertioned
strengthening angle-tie disposed at the corner of the bracket.

page_text: Figure 24 represents a section upon the dotted line, Figure 23, showing the
tie for the breaking of the joint at the angle of the bracket.
a are the double vertical webs of the bracket and b the single horizontal webs,
whilst the joint a', is bonded by an angle tie d, crossing the joint, and being, if
necessary, secured in position by rivets c².
Figure 25 represents a bracket made from solid-drawn or rolled T-section metal,
with a part of the vertical web mitre gapped as before.
Figure 26 represents a vertical section of Figure 25 on the dotted lines.
Figure 27 represents a bracket made from H-sectioned metal, mitre gapped at
about the middle as in the preceding brackets, and Figure 28 is a section of the
same upon the dotted lines a
Figure 29 is a cross section of a further form of bracket, in which the horizontal
single web has beaded edges.
Figure 30 is a further modified T shaped cross section, in which both the
horizontal and vertical webs are of a double thickness.
Figure 31 is a further section of metal, having a double vertical web.
Figure 32 is a U-shaped section metal from which angle brackets may be formed
according to my improvements.
Figure 33 represents a bracket in which the outer edge of the vertical web has
a beading a strengthened at the butt-joint a', by an insertioned wire angle
stay d.
Figure. 34 is a vertical section of Figure 33 on the dotted line 7.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
i
First. In shelf and like supporting brackets, making the same from thin sheet
metal of the various cross sections herein described and represented, by mitre-
gapping the said metal at the part where the angle of the bracket is to come, so
that when the length of section metal is bent to a right angle, the opposed edges
of the gap come together and make a butt-joint, substantially as described and set
forth.
Secondly. In shelf and like supporting brackets, making the same from thin
sheet metal fashioned into T or analogous cross sections, first gapping or square-
piercing the middle of the flat blank, so that when the said blank is bent up into
the desired cross section the fashioned strip becomes mitre-gapped or partly square-
gapped, substantially as described and set forth.
Thirdly. In shelf and like supporting brackets of the kinds referred to in the
preceding claims, strengthening the joint at the angle of the bracket by an
insertioned stay or insertioned angle stay, substantially as described and set forth.
Fourthly. The improvements in, and in the manufacture of, shelf and like
supporting brackets, substantially as herein described and set forth.
Dated this 11th day of April 1896.
