Improvements in and in the Manufacture of Eyed Attachment
Brackets of Window and Analogous Fittings.
I, MARK LAWTON, trading as John Lawton and Sons, of Harford Street, in
the City of Birmingham, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to attachments for supporting or securing window
and analogous fittings from or to standards or uprights, aiso to the manufacture
of such attachments.
The invention has reference principally to that type of attachment bracket
which is made of two half clips or semi-circular sections, adapted to be infibulated
with one another after having been introduced laterally around an upright, and
the objects of the improvements are, first, to provide a simple and ethcient
means for connecting together the sections and secondly, to reduce the cost of
manufacture and simplify the process of production.
One section or half of the improved attachment consists of a semi-circular
piece of metal of a depth corresponding to that of the eye attachment to be
made and with the end or edge parts having sufficient metal to admit of them
being turned into hollow sleeves or sockets for receiving the hooked or cranked
short inner ends of rods or brackets by or from which goods to be displayed, or
shelves or the like, are supported or suspended. At each of the webs or junction
parts coming between these side sockets with the curved body part, the band is
slit vertically downwards to an extent about equal to one half of its depth, to
admit of the sliding therein of corresponding slit or hook-like ends of the other
semi-circular clip section of the attachment, consisting of a semi-circular body
which is or may be a counterpart of the first-named section, and is preferably
cranked slightly at its two ends which are formed into hooks by slits or gaps
cut vertically upwards from the bottom edge to an extent about equal to one
half the depth of the band.
On the sliding and infibulation of the one part within the other after the said
semi-circular parts have been arranged to embrace a standard or upright, the
hook parts of the one engages the gapped parts of the other and so effects their
connection, when on the turning of a binding screw carried by one of the sections,
its inner end impinges against the upright and so locks the parts together.
As a modified form of such two-part fitting, the hooked ends of the one half
may be made much shorter than those of the fitting first described and are then
adapted to be introduced into gaps made in the ends of the other section, which
are longer than the said hooks, which may thus be introduced laterally into the
gaps and then engaged therewith by allowing them to slightly fall.
Instead of employing sockets or long sleeves for the ends of display rods, shelf
brackets or the like, I may employ ears, eyes, rests or their equivalent in lieu
thereof.
The halves of the sectional clip may be made from a length of drawn metal
of suitable section, from which pieces are cut off transversely and where sockets

page_text: are employed, the metal at the edges of the rolled length is either made of the
desired section in the rolling or is shaped by one or a succession of operations
to the desired figure. The parts may also be produced, shaped and fashioned
from flat blanks by means of dies or tools and pressure.

Improvements in and in the Manufacture of Eyed Attachment
Brackets of Window and Analogous Fittings.
I, MARK LAWTON, trading as John Lawton and Sons, of Harford 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 relates to attachments for supporting or securing window
and analogous fittings from or to standards or uprights, also to the manufacture
of such attachments.
The invention has reference principally to that type of attachment bracket
which is made of two half clips or semi-circular sections, adapted to be infibulated
with one another after having been introduced laterally around an upright, and
the objects of the improvements are, first, to provide a simple and efficient
means for connecting together the sections and secondly, to reduce the cost of
manufacture and simplify the process of production.
Figure 1 of the accompanying drawing represents an end elevation of an im-
proved attachment bracket constructed according to my invention.
Figure 2 shows the said bracket in topside plan whilst Figures 3 and 4
respectively represent back and front elevations thereof.
Figure 5 is a view showing an end elevation of the two detachable parts of the
bracket or fitting separately and Figure 6 represents them in plan.
Figure 7 shows a separate elevation of that part of the fitting which carries
the sockets for the reception of the turned-down of swinging shelf or like arms.
Figure 8 represents an elevation of the other part of the attachment carrying
the binding screw.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.
One section or half a, of the improved attachment consists of a semi-circular
body part a¹, or piece of metal of depth corresponding to that of the eye attach-
ment to be made and with the end or edge parts being turned into hollow sleeves
or sockets, for receiving the hooked or cranked short inner ends of swinging
window rods or brackets by or from which goods to be displayed, or shelves or the
like, are supported or suspended. At each of the webs or junction parts a³,
coming between these side sockets with the curved body part the band is slit
vertically downwards at a', to an extent about equal to one half of its depth, to
admit of the sliding therein of corresponding slit or hook-like ends b', of the other
clip section b, of the attachment, consisting of a semi-circular body 61, which is
or may be a counterpart of the first-named section, and is preferably cranked
slightly at 62, near its two ends 63, which are formed into the hooks 64, by making
slits or gaps b³, vertically upwards from the bottom edge 66, to an extent about
equal to one half the depth of the band.

page_text: On the sliding and infibulation of the one part within the other after the said
semi-circular parts have been arranged to embrace a standard or upright, the hook
parts of the one engages the gapped parts of the other and so effects their con-
nection, when on the turning of a binding screw c carried by one of the sections,
its inner end impinges against the upright and so locks the parts together.
Instead of employing sockets or long sleeves for the ends of display rods, shelf
brackets or the like, I may employ ears, eyes, rests or their equivalent in lieu
thereof.
The halves of the sectional clip may be made from a length of drawn metal
of suitable section, from which pieces are cut off transversely and where sockets
are employed, the metal at the edges of the rolled length is either made of the
desired section in the rolling or shaped by one or a succession of operations
to the desired figure.
Or the parts may be produced, shaped and fashioned from flat blanks by means
of dies or tools and pressure.
Thus the twin-socketted part a, may be made from a strip or blank of sheet
metal such as that represented in plan and edge view in Figure 9, which is
either fashioned by dies and pressure in the required shape with semi-circular
middle parts and sleeved ends as represented in Figure 10, after which gaps d,
are cut in the positions represented by the dotted lines, to receive the hooks of
the other section of the clip, or else the gaps may be cut whilst the strip is still
in the flat, as represented in Figure 11. The hooked section of the clip may,
in like manner, be fashioned from a metal blank such as that represented in
Figure 12, which is next gapped at the bottom edge to form the end hook con-
nections as shown in Figure 13. By suitable tools, the blank is then shaped
into a semi-circular figure as represented in Figure 14 and finally a screwed hole
is made at e, to receive the binding or clamping screw, as shown in elevation
in Figure 15 and in section in Figure 16.
Or instead of the hook gaps being cut out of the blank whilst in the flat, they
may be formed after the bending of the same into a semi-circular shape in
suitable parts of the ends, as represented by the dotted lines f, in Figure 16.
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:-
First: An attachment clip or bracket for window and analogous fittings,
comprising two separable sections, each coincidently gapped to form a hook
connection and made from sheet metal, substantially as herein described and
set forth.
Secondly:-
-The methods of producing or manufacturing attachment clips or
brackets for window and analogous fittings from sheet metal blanks, substantially
as herein described and set forth.
Dated this 29th day of August 1899.
