PROVIDIUNAL SPECIFICATION,
Improvements in the Method of Constructing Brackets, Stiffeners,
Gusset Stays, Beam Pockets, and the like, Used in Girder Work,
Steam Generators, and other Structures and Erections.
I, GEORGE TAYLOR, of The New Islington Girder Works, Ancoats, Manchester,.
in the County of Lancaster, Girder Maker, do hereby declare the nature of this
invention to be as follows:-
-
My said invention relates to improvements in and in the method of construct-
ing brackets, stiffeners, gusset stays, and the like, used for strengthening and
supporting purposes in metallic erections and structural work generally and is
intended to simplify their construction and lessen the cost of production.
Prior to my invention such brackets, stiffeners, and gusset stays, have been
forged and built up to the required shape such method of construction being
both tedious and costly.
Under my invention I construct the brackets stiffeners and similar stays from
rolled metal joists (girder section) or it might be channel iron or other section
of rolled metal.
The bracket, stiffener, or stay, is cut from a length of joist or channel iron or
it might be from a scrap end of such metal thereby utilizing what would otherwise
be accounted practically valueless. For instance a short length of joist or channel
iron may be cut diagonally thus forming two angle stiffeners. In stiffeners for
some purposes nothing else might be required.
In other instances, and particularly when constructing brackets, pieces of angle
iron or the like may be rivetted to such stiffeners, or a portion of the flange
could be cut away and the web bent to the required angle or curve. Such cut-
ting and bending of the web of the stiffener, or rivetting angle pieces thereto,
would of course vary according to the purpose for which the stiffener or stay
was required. Instead of bending the web, I may cut away a portion of the
web and bend the flange down onto the projecting angular web of metal.
By cutting diagonally, and flanging, pieces of channel or other iron and rivet-
ting such diagonally cut and flanged pieces to a flat or other suitably shaped
metallic plate I am enabled to readily construct a simple and inexpensive form
of beam pocket.
By thus utilizing metallic joists, channel iron, and the like, and cutting and
bending the same to the required formation, brackets, stiffeners, stays, and such
like strengthening and supporting parts can be cheaply and expeditiously
produced.

I, GEORGE TAYLOR, of The New Islington Girder Works, Ancoats, Manchester,

invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying.

My said invention relates to improvements in and in the method of construct-
ing brackets, stiffeners, gusset stays, and the like, used for strengthening and
supporting purposes in metallic erections and structural work generally and is
intended to simplify their construction and lessen the cost of production.
Prior to my invention such brackets, stiffeners and gusset stays have been
forged and built up to the required shape such method of construction being
both tedious and costly.
Under my invention I construct the brackets stiffeners and similar stays from
rolled metal joists (girder section) or it might be channel iron or other section
of rolled metal.
The bracket, stiffener, or stay, is cut from a length of joist or channel iron or
it might be from a scrap end of such metal thereby utilizing what would otherwise
be accounted practically valueless. For instance a short length of joist or channel
iron may be cut diagonally thus forming two angle stiffeners. In stiffeners for
some purposes this might complete the construction.
In other instances and particularly when constructing brackets, pieces of angle
iron or the like may be rivetted to such stiffeners, or a portion of the flange
could be cut away and the web bent to the required angle or curve. Such cut-
ting and bending of the web of the stiffener, or rivetting angle pieces thereto,
would of course vary according to the purpose for which the stiffener or stay
was required.
And in order that my invention may be fully understood I will now refer to
the various figs. contained in the accompanying three sheets of drawings.
In Figs. 1 to 3 I show my invention in one of its simplest forms, Fig. 1 being
a front elevation, Fig. 2 an end view and Fig. 3 a plan. A short length of
joista is cut diagonally the cut away portion being indicated in dotted lines.
To the diagonal portion of the joista thus obtained I rivet angle pieces bb and
thus readily and economically obtain a bracket suitable for bolting to wooden
beams or for bolting or rivetting to metal girders. In Figs. 4 and 5 I show in
side and end elevation a stiffener constructed from a diagonal cutting of joist c
to which is rivetted angle pieces d d. Figs. 6 and 7 show in side and end view,
a solid angle stiffener e rivetted to a joiste and formed with a turned down
flange e³. In Fig. 8 I show an elevation of a plated girder f to which is rivetted.
a double kneed stiffener 9 cut from channel section, whilst Fig. 9 illustrates
the girder with a single kneed solid stiffener.
A view at right angles to these figs. is shown at Fig. 10.
The knees of the stiffener gare formed by cutting away portions of the
web of the stiffener and bending down the flange as indicated in Fig. 10. The
stiffeners g are rivetted to the girder f angle pieces h being also used to connect
the stiffeners g to the girder f. A modified construction of this last arrangement
is shown in Figs. 11, 12 and 13. Fig. 11 shows in elevation a plated girder i
having rivetted thereto a double solid stiffener j cut from a girder section, further

page_text: secured by means of angle pieces k, the knees of the stiffener being constructed
as described. Fig. 13 shows in elevation a single kneed solid stiffener applied
in a similar manner, Fig. 12 being an end view of the two arrangements.
By cutting diagonally, and flanging, pieces of channel or other iron and rivet-
ting such diagonally cut and flanged pieces to a flat or other suitably shaped
metallic plate I am enabled to readily construct a simple and inexpensive form
of beam pocket.
In Figs. 14 to 16 I show such a method of constructing a beam pocket. Fig. 14
shows a diagonal cutting / from channel section flanged at two of which cut-
tings are rivetted to a flat base plate m as shown in Figs. 15 and 16 to form a beam
pocket.
It must be understood that the examples given do not by any means exhaust
the capabilities of my invention as any girder maker, or person skilled in the
construction of metallic structures could readily apply my invention in a variety
of ways in the construction of brackets, gusset stays, stiffeners and the like.
By thus utilizing metallic joists, channel iron, and the like, and cutting and
bending the same to the required formation, brackets, stiffeners, stays, and such
like strengthening and supporting parts, can be cheaply and expeditiously
produced.
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:-
Making or constructing brackets, stiffeners, gusset stays, beam pockets and the
like used in girder work, steam generators and metallic and other erections and
structures, from rolled metal joists, channel iron or other rolled section by
cutting and bending the same to the required shape with or without the addition
of angle or other pieces rivetted thereto in the manner and substantially as
described and shown
