A communication from FLORENT HIROUX, of Braine-le-Comte, in the Kingdom of
Belgium, Accountant.
I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex, M.I.M.E.
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to secure the hanging of looking glasses reflectors,
and other objects which require to be similarly hung in such a manner that they shall
assume naturally the requisite inclination without requiring to be fixed by meaning of
the usual locking devices.
A looking glass is generally required to lie at an angle to the vertical and not in a
vertical plane and to secure this various devices have been used such as a rack into
the teeth of which a projection from the frame of the glass fits, or the commonest of
all a jointed bearing, the two parts of which are drawn tight upon the pivot of the
glass by a thumb screw. This latter device however quickly wears out and becomes
useless. In carrying out this invention the usual plan is reversed and instead of
fixing the glass at the required angle it is so hung that it naturally assumes that angle
and no fixing is needed. This is accomplished by bringing the swinging axis a little
in front and above the centre of the glass; it will then naturally hang in the desired
position. The degree of inclination may be varied by altering the position of the
swinging centre which may be readily done by making the plate which carries the
pivot adjustable. Or the pivot may be adjustable in the plate as by having various
recesses to receive it. A simple form of plate is a straight plate screwed to the frame
of the glass and having recesses like a rack the pivot being placed in whichever of the
recesses will give the required inclination to the glass.
The form of plate or equivalent hanging device may be greatly varied; or it may
be produced in the frame of the glass itself.
If it was desired to tilt the top of the glass forward as is sometimes desired the
swinging centre would be placed behind the glass instead of in front of it; this
position is frequently required for reflectors..

page_text: I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex, M.I.M.E.
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 :-
The object of this invention is to secure the hanging of looking glasses and other
objects which require to be similarly hung in such a manner that they shall assume
naturally the requisite inclination without requiring to be fixed by means of the usual
locking devices.
A looking glass is generally required to lie at an angle to the vertical and not in a
vertical plane and to secure this, various devices have been used such as a rack into
the teeth of which a projection from the frame of the glass fits, or the commonest of all
a jointed bearing the two parts of which are drawn tight upon the pivot of the glass
by a thumb-screw. This latter device however quickly wears out and becomes
useless.
In carrying out this invention instead of fixing the glass at the required angle it
is so hung that it naturally assumes that angle and no fixing is needed. This is
accomplished by bringing the swinging axis a little in front and above the centre of
the glass; it will then naturally hang in the desired position. The degree of inclina-
tion may be varied by altering the position of the swinging centre which may be
readily done by making the plate which carries the pivot or pivot-bearing adjustable.
Or the pivot may be adjustable in the plate as by having various recesses to receive it.
A simple form of plate is a straight plate screwed to the frame of the glass and
having recesses like a rack the pivot being placed in whichever of the recesses will
give the required inclination to the glass or the reverse of this arrangement inay
be used.
The form of plate or equivalent hanging device may be greatly varied; or it may
be produced in the frame of the glass itself.
If it was desired to tilt the top of the glass forward as is sometimes desired
the swinging centre would be placed behind the glass instead of in front of it.
In the accompanying drawings figure 1 is a transverse vertical section of a looking
glass hung in its stand according to this invention, figure 2 is a front elevation of
portion of the same, figures 3, 4 and 5 are views drawn to an enlarged scale of
modified means for hanging looking glasses according to this invention.
Like letters indicate like parts throughout the drawings.
In the arrangement shown at figures 1 and 2, the frame A of the looking glass A¹
has screwed or otherwise secured to each of its vertical sides or edges a plate B in

page_text: the manner and relative position indicated at figure 1. The plate B is perforated
so that the pivot screw C may pass through it and screw into one of the
standards A2; or, if desired the screws C need not screw into the standards A²
but merely pass through and at the outer sides thereof be provided with nuts.
In the arrangement shown at figure 3 C represents the pivot secured to one of
the standards A and B the plate secured to the looking glass A¹ as in the
previous example the said plate being provided with the slot B₁ which enables the
looking glass to be lifted off its pivots C for cleaning or other purposes.
. In the arrangement shown at figure 4 C and B respectively represent the before-
mentioned pivot and plate the said plate in this example being provided with two
recesses B2 B2 in either of which the pivot C can be placed for supporting the
looking glass at either of the two inclinations which the raising or lowering of its
point of support in this manner provides for.
Although it is preferred to allow the looking glass or mirror to hang free it might
be arranged by having the heads C₁ of the pivot C sufficiently large (or other means
might be devised) to provide friction sufficient to retain it in any position into which
it may be moved.
Should it be desired that the looking glass occasionally slope with its top part
forward as is sometime required with large cheval glasses the axis of its swinging
pivots might be supported so that they could be moved from the back to the front of
the looking glass or vice versa. An arrangement by which this may be effected is
shown at figure 5 in which the plate B which is pivotted at D to the side of
the frame at its upper part carries the pivot C its lower part being formed with the
curved slot B³. The thumb-screw E passes through the slot B³ and screws into the
side of the frame. By this arrangement the pivots C which are supported on bearing
plates secured to the standards can obviously be moved either to the front or back of
the looking glass or mirror.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
Suspending a looking glass or mirror from an axis in front of the glass
and above its centre of gravity substantially as and for the purpose herein
described.
