PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Shelf and like Brackets.
We, PHINEHAS EDWARD AYTON, Manager of Pemberton and Sons, Limited, and
HENRY ROOKE, Works Foreman, both of Union Street, West Bromwich, in the
County of Stafford, do hereby declare the nature of this invention to be as
follows:-
This invention has relation to a new sheet-metal shelf or like bracket and to
the method of manufacturing or producing the same.
The bracket consists of a curved middle part with side webs or wings directed
backwards from it the boundary edges of which come at a right angle, with the
top or horizontal sides forming the shelf rest whilst the vertical sides come
against a wall or upright, to which the bracket is secured by screws or otherwise.
The curved front edge of the bracket is slightly set back or troughed to enhance
the strength of the article and brings portions of its metal up to the same bear-
ing level as the edges of the wing parts.
In carrying out the manufacture of a sheet metal-bracket of this type, we take
a lozenge or diamond blank of suitable thickness with short end extensions in the
direction of its longer axis. This blank is then curved by dies and pressure into
a semi-circular or parabolic figure and then the opposite sides are turned back
parallel with one another but separated by a space equal to the breadth of the
bracket. The outer boundary edge of the article makes a right angle whilst the
front edge of the same is inwardly troughed by suitable tools to give transverse
stiffness thereto. The bracket thus produced is open at the right angled top and
back and closed at the curved front, which is pierced with holes for the attach-
ment screws.

Improvements in and in the Manufacture of Shelf and like Brackets.
We, PHINEHAS EDWARD AYTON, Manager of Peniberton and Sons, Limited, and
HENRY ROOKE, Works Foreman, both of Union Street, West Bromwich, in the
[Price 8d.1

page_text: County of Stafford, 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 a new sheet-metal shelf or like bracket and to
the method of manufacturing or producing the same.
The improved bracket is represented in side elevation and edge view in
Figure 1, and in topside plan in Figure 2, of the accompanying drawings, and
consists of a curved front or middle part a, with side webs or wings b, directed
backwards from it the top and back boundary edges b', 2 of which are disposed
at a right angle relative to one another, with the top or horizontal edges b¹,
forming the shelf rest whilst the vertical edges or sides ³, come against a wall
or upright, to which the bracket is secured by screws or otherwise. The curved
front edge of the bracket is slightly set back or troughed to enhance the strength
of the article and bring portions of its metal up to the same bearing level as
the edges of the wing parts. This troughing of the curved front is clearly shown
in Figure 3, which is a section of Figure 1 upon the dotted line, and Figure 4
which represents the section of the bracket at the dotted line a¹.
In carrying out the manufacture of a sheet metal bracket of this type, we
take a lozenge or diamond blank c, such as represented in plan and edge view in
Figure 5, of suitable thickness with short end extensions in the direction of
its longer axis. This blank is then curved by dies and pressure into a semi-
circular or parabolic figure after which the opposite side parts, are turned
back parallel with one another but separated by a space equal to the breadth of
the bracket, which said space is marked d, in Figures 3 and 4. The outer
boundary edge of the article thus produced and which is represented in side
elevation in Figure 6 and in vertical section in Figure 7 thus lies respectively
in horizontal and vertical planes at a right angle to one another, the front edge
of the same is inwardly troughed by suitable tools to give transverse stiffness
thereto. The bracket thus produced is open at the top and back and closed at
the curved front a, which is pierced with holes a¹ (see Figures 1 and 2) for the
attachment screws.
Instead of fashioning the bracket from a lozenge shaped blank of sheet metal
as above described, we may, as a modification, produce the same from a rectan-
gular blank, the superfluous metal being removed by clipping or otherwise after
the shaping of the bracket itself has been completed.
The
Thus, in order to produce from sheet metal the shelf bracket shown in side
elevation in Figure 8, back elevation in Figure 9, vertical section in Figure 10,
in plan (looking from above onto the angle at the back) in Figure 11 and in
section on the dotted line 3 in Figure 12, we propose to take a rectangular
blank of suitable metal such as shown in Figure 13, and by means of suitable
press or stamping tools, fashion the bracket out of the middle of the same.
stamping produced by the first stage of the process is represented in Figures 14
to 16; Figure 14 showing a plan of the said stamping looking upon the angle or
corner, from the back, whilst Figure 15 represents a back elevation and
Figure 16 a side elevation of this rough stamping which is further shaped and
finished by subsequent processes.
Thus by means of suitable tools the blank figure 13 is bent transversely across
the middle into two right angled flanges or webs, whilst, by one or more pro-
cesses, the metal at or about the middle of the longer direction of the blank,
is fashioned or shaped roughly into the figure of the hollow or box bracket,
which shaped part is included in the angle of the two webs, which are
marked a, a in Figures 14, 15, and 16, whilst the bracket part is marked a.
The shaping of this bracket part is completed in one or more further processes,
and at the same time the front of the same is troughed at a³ to impart stiffness,
the stamping, at this stage having the configuration represented in vertical
section in Figure 17, in plan in Figure 18 which shows the front side, in back

page_text: elevation in Figure 19 and in transverse section on the dotted line 3, Figure 18,
in Figure 20.
The superfluous metal of the webs or flanges is now removed by clipping or
otherwise whereby the finished hollow or box-like bracket represented in
Figures 8 to 12 is produced.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
First: A shelf or like bracket made from sheet metal and consisting of a
curved or equivalent closed front, with side webs or wings directed backwards
from it, the top and back boundary edges of which said webs are disposed at a
right angle relative to one another, with the top or horizontal edges forming the
shelf rest whilst the vertical edges come against the wall or upright to which
the bracket is secured, substantially as herein described and also as set forth in
the accompanying drawings.
Secondly: The manufacture of shelf and like brackets, as referred to in the
preceeding claim, by stamping the same from a lozenge or diamond-shaped
blank, as described and set forth in Figures 5, 6, and 7 or from a blank of a
rectangular or similar shape, the superfluous metal being removed by clipping
or otherwise after the bracket has been formed, as described and set forth in
Figures 14 to 20.
