Improvements in Attaching and Fixing Adjustable Shop Window
Brackets and other like Brackets to Standards or Uprights.
I GEORGE CLARKE, Works Manager to Evered and Co. Limited Barnet
Works, Birmingham do hereby declare the nature of this invention to be as
follows:-
My invention consists of the construction and combination of the parts of the
appliances herein after described for attaching and fixing adjustable shop window
brackets and other like brackets to standards or uprights.
By my improvements the brackets are readily adjusted on their uprights or
standards without removal therefrom and are readily and securely fixed.
My improvements are specially applicable to adjustable shop window brackets
for supporting shelves in shop windows and I will describe them as applied to
such brackets.
I use a metal standard or upright on which the brackets slide and are fixed,
consisting of a flat bar and on the inner or fixing end of the bracket arm I form
a clamping box or frame for taking upon the flat standard or upright the said
clamping box or frame being provided with the clamping appliances hereinafter
described. The said clamping box or frame consists of two parallel branches or
plates the front plate being shorter than the back plate so as to form at the front
of the box a cleft or opening at which the clamping box can be passed onto the
standard or upright. The back of the clamping box is either formed of a continuous
plate or of a fork. The edge of the back plate or ends of the fork of the
clamping box are turned at right angles and constitute claws for the edge of the
flat standard or upright to bear against. Within the clamping box and lying
against the shorter front part, is a clamping plate having nearly the same length
and breadth as the said front part of the clamping box. By means of a pin on the
clamping plate taking into a hole in the front of the clamping box, the said clamping
plate is made capable of a slight sliding motion to and from the said front of the
box and the clamping plate is secured in its place by its ends being turned over
the ends of the front part of the clamping box. In the middle of the front part
of the clamping box is a screwed pummel or screw box in which a clamping screw
works, the inner end of the said screw bearing against the clamping plate. By
driving home the clamping screw it bears against the clamping plate and forces it
towards the back of the clamping box and causes the standard or upright
to be gripped firmly between the said clamping plate and the back of the clamping
box.
In order to attach the adjustable bracket to and fix it on the flat upright, the
clamping screw is relaxed so as to permit the clamping plate to bear closely against
the front of the clamping box. The clamping box is now passed by its cleft or
opening onto the standard and by driving home the clamping screw the bracket is
securely fixed to the standard. By relaxing the clamping screw, the clamping
plate no longer binds the clamping box to the standard and the bracket can by a
sliding motion be adjusted on the upright or standard and by afterwards driving
home the clamping screw the adjusted bracket is fixed in its place.

Improvements in Attaching and Fixing Adjustable Shop Window
Brackets and other like Brackets to Standards or Uprights.
I, GEORGE CLARKE, Works Manager to Evered and Co. Limited, Barnet
Works, Birmingham, 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 consists of the construction and combination of the parts of the
appliances hereinafter described for attaching and fixing adjustable shop window
brackets and other like brackets to standards or uprights.
By my improvements the brackets are readily adjusted on their uprights or
standards without removal therefrom and are readily and securely fixed. The
brackets are also capable of being readily placed on and removed from the uprights
or standards.
My improvements are specially applicable to adjustable shop window brackets
for supporting shelves in shop windows and I will describe them as applied to such
brackets.
I use a metal standard or upright on which the brackets slide and are fixed
consisting of a flat bar and on the inner or fixing end of the bracket arm 1 form a
clamping box or frame for taking upon the flat standard or upright, the said
clamping box or frame being provided with the clamping appliances hereinafter
described. The said clamping box or frame consists of two parallel branches or
plates the front plate being shorter than the back plate so as to form at the front of
the box a cleft or opening at which the clamping box can be passed onto the
standard or upright. The back of the clamping box is either formed of a
continuous plate or of a fork. The edge of the back plate or ends of the fork of
the clamping box are turned at right angles and constitute claws for the edge of the
flat standard or upright to bear against. Within the clamping box and lying
against the shorter front part is a clamping plate having nearly the same length
and breadth as the said front part of the clamping box. By means of a pin on
the clamping plate taking into a hole in the front of the clamping box, the said
clamping plate is made capable of a slight sliding motion to and from the said
front of the box and the clamping plate is secured in its place by its ends being
turned over the ends of the front part of the clamping box. In the middle of the
front part of the clamping box is a screwed pummel or screw box in which a
clamping screw works the inner end of the said screw bearing against the clamping
plate. By driving home the clamping screw it bears against the clamping plate
and forces it towards the back of the clamping box and causes the standard or
upright to be gripped firmly between the said clamping plate and the back of the
clamping box.
In order to attach the adjustable bracket to and fix it on the flat upright, the
clamping screw is relaxed so as to permit the clamping plate to bear closely
against the front of the clamping box. The clamping box is now passed by its
eleft or opening onto the standard and by driving home the clamping screw the
bracket is securely fixed to the standard. By relaxing the clamping screw, the
clamping plate no longer binds the clamping box to the standard and the bracket
can by a sliding motion be adjusted on the upright or standard and by afterwards
driving home the clamping screw the adjusted bracket is fixed in its place.
Figure 1 of the accompanying drawing represents in side elevation; Figure 2 in
plan of upperside and Figure 3 in vertical section, a shop window bracket attached
and fixed to the upright or standard according to my invention.
The same letters of reference indicate the same parts in Figures 1, 2 and 3.
a is the arm of the shop window bracket and b is the flat metal bar, standard or
upright on which the bracket slides and is fixed, the said standard or upright being

frame made preferably in one piece with the arm a of the bracket, for taking upon
the flat standard or upright b. The clamping box consists of two parallel branches.

back plate c so as to leave a cleft or opening d between them at the front of the
box, at which cleft the clamping box can be passed onto the standard or upright b.

It will be seen by an examination of the section Figure 3 that the clamping
plate e is capable of a slight sliding motion to and from the front of the box,
a guide pin f on the said front taking into a hole in the clamping plate. The
clamping plate e is secured in its place by its ends being turned over the ends
of the front part 2 of the clamping box in the manner seen in Figure 3; is.
the clamping screw working in a screwed pummel or screw box projecting
from the front part of the clamping box, the inner end of the clamping screw
bearing against the clamping plate e so that the said plate can be forced or:
advanced towards the back c of the clamping box or permitted to retire to the
front of the said box.
To attach the adjustable bracket a to and fix it on the flat upright b the clamping
screw g is relaxed so as to permit the clamping plate e to bear closely against the
front of the clamping box. The clamping box is now passed by its cleft or
opening at d onto the standard band by driving home the clamping screw git forces
the clamping plate e towards the back of the clamping box and causes the
standard or upright to be gripped firmly between the said clamping plate e and
the back c of the clamping box as seen in the drawing.
In order to adjust the position of the bracket a on the upright it is only
necessary to relax the clamping screw g. As the clamping plate e no longer binds.
the clamping box to the standard, the bracket can by a sliding motion be adjusted
on the standard and again fixed in its adjusted position by driving home the
clamping screw. Or when the clamping screw is in its relaxed position the
bracket can be wholly withdrawn from the standard.
The clamping plate may be dispensed with and the clamping screw be made
to bear directly on the upright. This modification is represented in side
elevation in Figure 4; plan of upper side in Figure 5 and vertical section in
Figure 6.
In this modification the inner end of the clamping screw g is provided
with a disc or enlargement i so as to increase its bearing surface upon the
standard.
The action of this modification is essentially the same as that of the bracket
first described and corresponding parts are marked with the same letters of
reference.
apply my improvements to brackets other than shop window brackets,
substantially as hereinbefore described and illustrated with respect to shop window
brackets.
Having now particularly described and ascertained the nature of my inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention;-
The improvements in attaching and fixing adjustable shop window brackets
and other like brackets to standards or uprights hereinbefore described and
illustrated in the accompanying drawing that is to say, the combination with the
inner end of the bracket arm of a clamping box or frame of the construction

page_text: described and illustrated for taking upon the flat upright or standard on which
the adjustable bracket is to be attached and fixed, and the use with the said
clamping box or frame of a clamping screw and clamping plate or a clamping
screw only for fixing the clamping box or frame to the said flat upright or standard,
the several parts being constructed and arranged and used substantially as described
and illustrated.
