PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Shop Window Brackets and
other like Metallic Brackets.
I, GEORGE WHITEHOUSE of Barford Street Tube Works Birmingham in the
County of Warwick Tube Manufacturer do hereby declare the nature of this
invention to be as follows :-
My invention has reference to metallic brackets in which the arms are notched
or have semi-circular or other shaped depressions in their upper edges, the said
brackets being principally used in shop windows for supporting and displaying goods
or articles, but the said brackets are also fixed to shelves and are used generally
where goods or articles are to be supported and displayed. The arms of brackets
of this kind are either jointed so as to be capable of rising and falling; or are
fixed to the carrying plates, and are ordinarily made by casting.
My invention consists in manufacturing the arms of the said brackets from sheet
metal by the process or combination of processes herein after described, whereby
their manufacture is economized.
I will describe my invention as applied to the manufacture of the arm of a rising
and falling shop window bracket. I cut out at a press, a blank of sheet brass or
other ductile sheet metal or alloy having plain or ornamented edges, the said blank
having the length of the arm to be made and a breadth a little more than double
that of the arm to be made. I pierce the middle of the blank with a series of equi-
distant holes or piercings, the ends of which have a nearly semi circular or other
figure. I next bend or fold the pierced blank or strip along its middle so as
to bring the two folded parts parallel and nearly in contact. There is thereby
produced a bracket arm the lower edges of which are plain or ornamented and the
upper edges are notched or furnished with depressions of the kind ordinarily made
in notched brackets, the parallel parts of the arm being joined at their upper edges
by the bent webs or uncut-away parts left between the piercings in the blank.
The joint of the arm is formed by inserting and pinning between the branches or.
parallel parts at one end thereof, a middle knuckle which is fitted between and
jointed to the side knuckles of a fixed vertical carrier the peg of which takes into
the ordinary socket on the shop window, shelf or other fixed support. The middle
knuckle piece of the bracket arm carries the screw box in which the adjusting
screw of the bracket works for adjusting the position of the rising and falling arm
as is well understood.
When the bracket arms are made from thin sheet metal they be strengthened by
making on the sheet metal blank longitudinal ribs preferably near the edges of the
blank. These ribs when the blank has been folded are situated on the inner sides
of the folded parts and bear against each other.
Dated this Twentieth day of October 1894.

other like Metallic Brackets.
I, GEORGE WHITEHOUSE, of Barford Street Tube Works, Birmingham in the
County of Warwick, Tube Manufacturer, do hereby declare the nature of my
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :--
My invention has reference to metallic brackets in which the arms are notched
or have semi-circular or other shaped depressions in their upper edges, the said
brackets being principally used in shop windows for supporting and displaying
goods or articles but the said brackets are also fixed to shelves and are used
generally where goods or articles are to be supported and displayed. The arms of
brackets of this kind are either jointed so as to be capable of rising and falling; or
are fixed to the carrying plates and are ordinarily made by casting.
My invention consists in manufacturing the arms of the said brackets from sheet
metal by the process or combination of processes hereinafter described, whereby
their manufacture is economized.
I will describe my invention as applied to the manufacture of the arm of a rising
and falling shop window bracket. I cut out at a press, a blank of sheet brass or
other ductile sheet metal or alloy having plain or ornamented edges, the said blank
having the length of the arm to be made and a breadth a little more than double
that of the arm to be made. I pierce the middle of the blank with a series of equi
distant holes or piercings, the ends of which have a nearly semi-circular or other
figure. Inext bend or fold the pierced blank or strip along its middle so as to
bring the two folded parts parallel and nearly in contact. There is thereby
produced a bracket arm the lower edges of which are plain or ornamented and the
upper edges are notched or furnished with depressions of the kind ordinarily made
in notched brackets, the parallel parts of the arm being joined at their upper edges
by the bent webs or uncut away parts left between the piercings in the blank.
The joint of the arm is formed by inserting and pinning between the branches or
parallel parts at one end thereof, a middle knuckle which is fitted between and
jointed to the side knuckles of a fixed vertical carrier the peg of which takes into
the ordinary socket on the shop window shelf or other fixed support. The outer
knuckle piece of the bracket arm carries the screw box in which the adjusting
screw of the bracket works for adjusting the position of the rising and falling arm
as is well understood.
When the bracket arms are made from thin sheet metal they may be strengthened
by making on the sheet metal blank longitudinal ribs preferably near the edges of
the blank. These ribs when the blank has been folded are situated on the inner
sides of the folded parts and bear against each other.
Figure 1 of the accompanying drawing represents in side elevation and Figure 2
in plan, partly in horizontal section the sheet metal notched arm of a rising and
falling shop window bracket made according to my invention ;
and
Figure 3 represents the pierced blank or strip from which the said arm is made
Figure 4 represents in side elevation, plan and cross section, the notched arm
made by folding or doubling longitudinally the blank at its middle;
Figure 5 represents the middle knuckle piece of the joint.
In the drawing, the notched sheet metal bracket arm is marked a and the middle
knuckle between the branches or parallel parts at one end of the bracket arm is
marked b, the said middle knuckle being pinned at c to the said branches; d is the
joint pin on which the arm turns passed through the said branches and the middle

page_text: and outer knuckles b, e, the peg on the outer knuckle e taking into the ordinary
socket in the shop window, shelf or other support; fis the adjusting screw taking
into a screw box in the outer knuckle e for adjusting the position of the rising and
falling bracket arm a.
In making the notched arm I take the blank or strip of sheet brass, or steel or
other ductile sheet metal or alloy represented in Figure 3. The said blank has an
ornamental edge (it may however have a plain edge) and has a breadth a little
more than double that of the arm to be made. The middle of the blank is pierced
with a series of equi-distant holes or piercings 9, 9, with semi-circular ends, but the
shape and position of the piercings may be varied. One end of the blank is pierced
with joint holes h for jointing the bracket arm to the support. By means of press
tools worked in a press the pierced blank Figure 3 is bent or folded along its.
middle so as to bring the folded parts parallel and nearly in contact as represented
in Figure 4, thereby producing a sheet metal bracket arm the lower edges of
which are ornamented and the upper edges are notched or provided with equi-
distant depressions g of the ordinary kind. It will be seen by an examination of
Figures 1 and 4 that the parallel parts of the sheet metal bracket arm a are joined
by the bent connecting websi, that is to say, by the uncut away parts left between
the piercings g, g in the blank.
After the arm has been thus formed, the middle knuckle piece 6 Figure 5 is.
inserted between the parallel parts or brauches of the arm at one end and pinned
thereto at c.
The arm is then jointed at d to the outer knuckle piece e in the
usual way.
My improvements are applicable to the manufacture of notched bracket arms
which are fixed to the carrying plates or fixed supports instead of being jointed
thereto.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention;
Manufacturing the notched arms of shop window brackets and other like metallic
brackets from ductile sheet metal or alloy by the process or combination of
processes hereinbefore described and illustrated in the accompanying drawing;
that is to say, taking a pierced sheet metal blank essentially of the kind described
and represented and bending or folding it along its middle and bringing the two
folded or doubled parts parallel and nearly in contact and finishing the joint end or
part to be connected to the fixed support by inserting and pinning between the
branches or parallel parts at one end of the arm, a middle knuckle substantially as
described and illustrated.
