Improvements in the Construction of Wrought Metal Brackets.
I, HERBERT HENRY GREEN, of Gothic Works, Herrick Street, Wolverhampton,
in the County of Stafford, Hardware Manufacturer, do hereby declare the nature
of this invention to be as follows:
-
The object of this invention is to construct wrought metal brackets, such for
instance as those used to support shelving and the like, and particularly those
which are required to be of steel, in a manner which combines strength with
economy of manufacture to a degree not heretofore or usually attained.
The back or flange of both the horizontal and vertical members of each bracket
is formed from a length of bar which is rolled with a pair of fillets running
lengthways along the middle of the inner face thereof but which leave between
them a groove to receive the inner edge of the web. These two members of a
bracket are formed in one continuous length of metal which is simply bent at the
part where the one member joins into the other. The webs are formed, preferably,
to mitre at the angle where they meet, and have rivets formed to project from their
inner edges, and holes to receive the rivets are formed through the portions of
the flanges which are between the fillets. The webs are fixed by means of their
rivets, but the fillets between which their inner edges pass tend greatly to stiffen
the webs, and render the rivets less liable to fracture through sideway force exerted
against the webs than would otherwise be the case; so great support indeed do
the fillets afford the webs that a web may be fixed by a single rivet only, especially
if the web is somewhat short. The fillets, also, add greatly to the strength of the
flanges.
The stay or strut may be fixed at its end in any convenient manner.
In some cases I omit the webs altogether, and pass the ends of the stay or strut
between the fillets of the flanges and fix its ends to the flanges by means of rivets,
as in the case of fixing the webs.

Improvements in the Construction of Wrought Metal Brackets.
I, HERBERT HENRY GREEN, of Gothic Works, Herrick Street, Wolverhampton,
in the County of Stafford, Hardware Manufacturer, do hereby declare the nature
of this invention, and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
The object of this invention is to construct wrought metal brackets, such for

page_text: instance as those used to support shelving and the like, and particularly those
which are required to be of steel, in a manner which combines strength with
economy of manufacture to a degree not heretofore or usually attained.
The back or flange of both the horizontal and vertical members of each bracket
is formed from a length of bar which is rolled with a pair of fillets running
lengthways along the middle of the inner-face thereof but which leave between
them a groove to receive the inner edge of the web. These two members of a
bracket are formed in one continuous length of metal which is simply bent at
the part where the one member joins into the other. The webs are formed, pre-
ferably, to mitre at the angle where they meet, and have rivets formed to project
from their inner edges, and holes to receive the rivets are formed through the por-
tions of the flanges which are between the fillets. The webs are fixed by means of
their rivets, but the fillets between which their inner ends pass tend greatly to
stiffen the webs, and render the rivets less liable to fracture through sideway force
exerted against the webs than would otherwise be the case; so great support indeed
do the fillets 'afford the webs that a web may be fixed by a single rivet only,
especially if the web is somewhat short. The fillets, also, add greatly to the
strength of the flanges.
The stay or strut may be fixed at its end in any convenient manner.
In some cases, I omit the webs altogether, and pass the edges of the outer ends
of the stay or strut between the fillets or flanges and fix its ends to the flanges
by means of rivets, as in the case of fixing the webs.
In order that the invention may be clearly understood, I will now proceed to
describe the same with reference to the accompanying drawings, of which, Figure 1
is a side elevation of a bracket in which both webs and a stay are employed,
Figure 2 is a front elevation of the bracket shewn by Figure 1, Figure 3 is a
section taken on line of Figure 1, Figure 4 is a side elevation of a bracket in
which the webs are dispensed with, and Figure 5 is a detached view shewing the
sectional shape of the metal which constitutes the portions of the horizontal and
vertical members to which the webs are fixed in the case of the bracket shewn
by Figure 1, and entirely constitutes such members in the case of the bracket
shewn by Figure 4.
Referring first to Figures 1, 2, 3 and 5, the backs or flanges A and A¹ of the
horizontal and vertical members of the bracket, are formed from a short length of
metal bar which, as most clearly shewn by Figure 5, has been rolled with a pair
of ribs or fillets a running lengthways along the middle thereof. These fillets are
in such position in relation to one another that there is only just sufficient room
between them to admit the edges of the webs B B. The inner edges of the webs
are inserted within the groove formed between the nilets a a, and the webs are,
preferably, mitred at the angle where they meet, and are secured in place by
rivets which are formed to project from their inner edges and pass through holes
formed through the back or flanges A A. The webs are shewn as: fixed to the
flanges each by means of two rivets, and this is preferred, but, as above stated,
each web may, if desired, be secured to its flange by means of a single rivet only.
The strut Cis, conveniently, formed as a malleable casting with ears c formed on
each end thereof which pass across the opposite sides of the webs, and through
which rivets are passed to secure it to the webs. In lieu of forming the strut as
a malleable casting, it may, of course, be formed as a strip of wrought metal
having plain ends which are riveted to the webs.
In the modification shewn by Figure 4, the webs are dispensed with, and the
horizontal and vertical members correspond with the backs or flanges above de-
scribed, and are similarly lettered. The strut C¹, is of a thickness to just pass
into the groove formed by the fillets a a, and is, preferably, formed of a shape
which enables a considerable portion of the length of each end thereof to be
passed between the fillets, and is secured in position between the fillets a, by
means of rivets 61 which are formed to project from its inner edge and are passed
through the members A A¹.

page_text: The fillets a a, besides lending very considerable sideway support to the webs,
or strut, as the case may be, add very greatly to the strength of the portions A A¹.
Brackets constructed according to this invention are cheap in manufacture,
and are strong, light, and very neat in appearance.
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:
-
1. A bracket having edges of webs of the horizontal and vertical members, or
portions of the inner edge of a strut, between ribs or fillets running along the
inner faces of the backs or flanges of such members, or along the inner face of
the metal constituting such members, such ribs or fillets being spaced such dis-
tance apart only as to just admit between them the webs or strut, substantially
as described.
2. A bracket constructed substantially as described with reference to Figures 1,
2 and 3, of the drawings herewith.
3. A bracket constructed substantially as described with reference to Figure 4
of the drawings herewith.
