An Improved Looking-glass Adjustment.
I, WILLIAM EDWARD Norris, of Wood Norton, East Dereham, Norfolk,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved adjustment for swinging or pivotted
looking-glasses and comprises a curved metal plate secured to the side of the
looking-glass frame and a spring attached to the support of or stand for the glass,
and adapted to engage with and press against the edge of the said metal plate
and by the friction between the two parts to hold the glass at any desired angle.
The curved edge of the said metal plate is struck with the pivot of the glass as
the centre and the edge is preferably milled or provided with shallow notches or
the like and the spring may have a tooth or two or more teeth to engage the said
notches and thereby increase the hold of the spring on the plate.
I preferably arrange one of my improved adjustments on both sides of the
looking-glass as in that case the springs may be lighter and moreover a more
symmetrical appearance is given to the looking-glass than if the device is arranged
only on one side thereof.
In some instances the curved plate is secured to the support or stand for the
glass, and the spring to the glass frame.
My improved adjustment is very cheap, is easily fixed to new or old glasses and
does not quickly wear out or get out of order.

I, WILLIAM EDWARD NORRIS, of Wood Norton, East Dereham, Norfolk,
Gentleman, 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:-
My invention relates to hinged or pivoted looking-glasses and provides an
improved device for retaining the looking-glass in any position to which it may be
set. The said device is hereinafter termed an adjustment and comprises a curved.
metal plate secured to the looking-glass frame and a spring attached to the support
or stand for the looking-glass, or rice versa that is to say the curved metal plate
may be attached to the support or stand and the spring to the looking-glass frame,
the spring in either case being adapted to engage with and thereby to hold the
glass at auy. desired angle.
The curved edge of the said metal plate is concentric with the pivot of the
looking-glass. It is preferably milled or provided with serrations or teeth or the
like, and the spring has a tooth or two or more teeth to engage with the serrations
and thereby ensure a firm hold between the spring and the plate.
I preferably arrange one of my improved adjustments on each side of the

page_text: looking-glass as in that case the device may be lighter and a more symmetrical
appearance is given to the looking-glass than if the device is arranged only on one
side thereof.
Referring to the accompanying drawings which illustrate my invention
Figure 1 is a side view of a looking-glass fitted with my improved adjustment.
Figure 2 is a rear view of a portion of the looking-glass.
Figures 3 and 4 are similar views illustrating a slightly modified form of my
improved device.
Like letters denote corresponding parts in the several figures.
A is the hinged or pivoted looking-glass; B is the support or stand therefor.
C is a curved metal plate which in Figures 1 and 2, is shown secured to the side
of the looking-glass frame, and in Figures 3 and 4 is shown secured to the support
or stand. In both cases the curved edge of the plate is concentric with the
pivot A of the looking-glass. D is a spring plate shown secured in Figures 1
and 2 to the support or stand, and in Figures 3 and 4 to the looking-glass.
The plate C has a serrated or notched or toothed curved edge as shown, and
the spring plate D is furnished with a tooth D₁ adapted to engage with the
notches or teeth of the plate C and thereby to hold the looking-glass at any
angle to which it may be set. The position of the looking-glass can be instantly
adjusted by simply turning the same, the spring plate D being sufficiently flexible
to allow the tooth D' to slide readily over the teeth of the plate C when the
looking-glass is being turned about its pivots. The shape of the spring plate may
be varied to suit its position of attachment to the stand or to the looking-glass.
Moreover any suitable form of spring may be used. In all cases the spring is
arranged to exert a pressure on the edge of the plate which pressure will be uniform
in all positions of the looking-glass. I may provide one of my improved adjustments
on one side only of the looking-glass or I may provide one on each side in which
case a lighter adjustment may be employed.
In some cases I dispense with the teeth of the plate and rely upon the pressure
of the spring on the plain curved edge of the plate for maintaining the looking-
glass in position. The curved edge of the plate may be a semi-circle or any
smaller fraction of a circle.
In some instances, for example when the looking glass frame and standard
are made of metal the curved plate and spring may be integral with the frame or
standard.
My improved adjustment is very cheap, it is easily fixed to new or old looking-
glasses, and does not quickly wear out or get out of order.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A looking-glass adjustment comprising a plate having a plain or serrated
curved edge concentric with the pivot of the looking glass, and a spring plate
adapted to press against said curved edge, one of the parts being attached to
the looking-glass frame and the other to the support or stand, substantially as
described.
2. A looking-glass adjustment constructed substantially as described with
reference to either of the forms illustrated in the accompanying drawings.
