Apparatus connected with Supporting Adjustable Mirrors for
Dressing Tables and other like Mirrors.
HARMAN JOHN HOWLAND GRAVES, 1, Tamar Terrace, Devonport, Furnishing
Warehouseman, do hereby declare the nature of this invention to be as follows:-
This invention consists of the hereindescribed apparatus connected with sup-
porting adjustable mirrors.
To carry this invention into effect I provide a metal plate and a metal stock-
head.
The metal plate is longer than wide at its back surface and flat or concave
according to the outline of the side flat of the mirror frame it is required to
support its front surface is preferably circular and flat.
The stock-head has a front face corresponding to the front face of the metal
plate.
These parts are connected together preferably by a screw bolt passing hori-
zontally through each, they are connected in such a way that when the stock
head is pivotally connected to a suitable standard the plate part is itself free to
rotate on its horizontal axis.
To suspend a mirror the plate part of the apparatus is secured centrally against
the side flat of the mirror frame and the stock head part of the apparatus is
pivotally secured upon the apex or top of a vertical fixed standard.
The stock-head may be secured upon the apex of a suitable standard either by
means of a vertical dowell pin cast in one with it upon its underside being fitted
into a corresponding metal socket sunk down into the standard, or by being cast
with a vertical hole in its underside fitting down upon an upstanding dowell pin
rising from the standard top.
The angle adjustment of the mirror is secured preferably by the head of the
connecting bolt being recessed in the back surface of the metal plate, its opposite
end being in screw form projecting beyond the stock head this screw end is fitted
with a suitable thumb turn nut which upon being tightened up against the stock
head brings all the parts into strong frictional contact. The angle adjustment of
the mirror may also be secured by the following method, the head end of the
connecting bolt may be of ball shape projecting beyond the back surface of the
plate part of the apparatus in which case the other end of the bolt terminates in
and is made fast in the stock-head this projecting ball head is passed into a metal
socket which is let centrally into the side edge of the mirror frame, this socket
has one free side formed by a hinged grip plate this is screwed down tightly upon
the projecting ball head holding the same in a firm grip thus setting up frictional
contact sufficient to maintain the mirror at any desired inclination.

I, HARMAN JOHN HOWLAND GRAVES, of 1, Tamar Terrace, Devonport, in the
County of Devon, Furnishing Warehouseman, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
-
This invention relates to apparatus for supporting adjustable mirrors such as
those used for dressing tables.
According to the invention I construct the mirror support of a plate adapted
to be secured to the side of the mirror frame and of a stock-head which is pivotally
connected to the said plate and is provided with an upright stem adapted to fit
loosely in a socket in a suitable standard. The metal plate and the stock-head are
connected together by a horizontal pin or the like so that the mirror can swing
upon the said pin, means being provided for locking the pin.
With this arrangement, therefore, the mirror can be adjusted to any inclination
to the horizontal and vertical planes.
To enable the invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is a sectional elevation of a mirror movement made according to the
invention, the said device being shewn attached to a mirror:
Figure 2 is a side view thereof; and
Figure 3 is a view similar to Figure 1 of a slightly modified construction of
device.
A is the mirror (of which a portion only is shewn in the drawing) and a is
the metal plate which is secured to the frame of the mirror A by suitable means,
such for example as the bolts a¹, a¹ shewn in the drawing. b is the stock-head,
the said stock-head being provided with a downwardly extending pin b¹ and with
a horizontal hole formed through it so as to provide a horizontal pivot upon
which the mirror A can be swung.
Referring first to the arrangement illustrated in Figures 1 and 2 c is the pin
which is passed through a horizontal hole in the plate a, the said plate a being
provided on the face which is in contact with the frame of the mirror A with a
recess to receive the head c¹ of the said pin. The outer end of the pin is reduced
in diameter, a portion d of the reduced part being made square and the remaining
portion of the reduced end being formed with a screw-thread. A washer e fits
on to the square portion d of the pin c and also fits within a square recess in
the end of the stock-head 6 and a nut f is provided for screwing upon the screw-
threaded end d¹ of the pin c, (which said screwthreaded end projects beyond the
outer face of the stock-head) so as to secure the whole in position. The cylin-
drical extension 61 of the stock-head is adapted to loosely fit into a socket formed
in a suitable standard or support not shewn in the drawing.
With this arrangement it will be obvious that by screwing up the nut f the
head of the pin c presses the mirror plate a and the stock-head b tightly into
contact so as to hold the mirror A in the position in which it is adjusted, to alter
the inclination of the mirror it is simply turned upon the pin c with is rigidly
held in the stock-head b by means of the washer e The mirror A can also be
turned into any vertical plane by turning the cylindrical extension 6' in its socket.
In the arrangement illustrated in Figure 3 the plate a, instead of being
arranged to turn upon the pin c, has the said pin formed integral with it. The
pine is passed into a horizontal hole in the stock-head which is provided with

page_text: the downward extension 61 as hereinbefore described. The outer end of the
pin c is formed with a flat and projects beyond the outer face of the stock-
head so as to take a washer e; the outer end of the pin c is made hollow and is
provided with an internal screw-thread to enable it to receive a screw g. Or
instead of being made hollow and internally screw threaded the pin beyond the
flat can terminate in a screw adapted to receive a nut as in the arrangement
described in Figures 1 and 2.
With this arrangement when the screw g is tightened, all the parts of the
apparatus are brought into strong frictional contact sufficient to hold the mirror A
at any angle of inclination.
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:-
The manufacture and use of mirror supports constructed substantially as
herein before described and illustrated in the accompanying drawing
