Improvements in and Connected with Looking Glass Centres and
like Centres.
I, CHARLES FREDERICK HALL 2 Crogsland Road Chalk Farm London N.W.
Storekeeper do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to improve the bearings on which dressing cheval
and other looking glasses are balanced centred and held in position. And it may be
used on any apparatus to which it can be suitably applied.
Fig. I on the drawings accompanying this specification represents a perspective
view of my apparatus attached to an ordinary dressing glass. The standard on which
the glass is balanced is shown at A and B shows the frame of the glass. The plate C
is attached to the standard A and is also shown at Fig. 2. The plate D which is
fastened to the glass frame B is also shown at Fig. 3 and is centred on the pin E
which enters the hole or socket F (Fig. 3). On this pin and socket the glass is centred
and balanced.
The screw Fig. 4 is tapped into the hole G on the plate C and is for the purpose of
pressing the 2 plates (and D together and is accompanied by a washer Fig. 5. When
the screw (which slides freely in the slot H H) is tightened it presses the 2 plates
together thus forming a kind of break so that the glass may be held in position yet
freely moved at any angle at discretion. When the glass is moved it is the plate D
which revolves while the pin and plate C and the screw and washer remain
stationary.
Instead of the washer Fig. 5 a plate as Fig. may be employed. The hole or
socket N fits on the pin E after the pin has passed through the plate D. The hole K
is for the screw to pass through in the same way as through the washer. The form
and shape of the plate D may be altered and modified suitable for its employment in
connection with the plate Fig. 6. The washer Fig. 5 may be made in section as
Fig. 7 so as to fit in the slot H H to prevent the washer turning with the screw.
The form of the screw need not be confined to the shape shown herewith but may
be made with a countersunk square sexagon or other head or a thumbscrew to turn

page_text: with the fingers may be used. Or a tapped pin may be fastened to plate C to slide in
slot H H and a loose nut of any description be used.
Two of the centerages above described may be employed on a glass or one only and
a simple socket and bearing as shown at Figs. 9 and 10 be used at the other end.
It sometimes happens that a greater distance is required between the standard A
and the glass frame B than is shown at Fig. I to make out this distance the plates C
and D are thickened or a pin and plate as shown at Fig. 8 is attached to the plate C.
On to this pin a washer or collar ornamental or otherwise may be added. The pin on
Fig. 9 to be treated in the same way. The letters S. S. show screw-holes which may
be worked in any position or any number on the plates.
The shapes and proportions of the various parts of my invention and their relation
to each other on the drawings herewith are not intended to illustrate the exact form
they shall take but I may modify diminish enlarge or re-arrange them in the manner
most suitable to effect my purpose. For instance the pin E may be attached to the
plate D instead of the plate C. Or plate D be fastened to the standard A and the
plate C to the glass frame. Or the screw may be tapped into the washer or into
the plate shown at Fig. 6.
They may be made in any material.

Improvements in and Connected with Looking Glass Centres and
like Centres.
I, CHARLES FREDERICK HALL (Storekeeper) No. 2 Crogsland Road Chalk Farm
London N.W., do hereby declare the nature of my said 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 my invention is to improve the bearings on which dressing, cheval
and other looking glasses are balanced centred & held in position and it may be used
on any contrivance to which it can be suitably applied.
Fig. I on the drawings accompanying this specification represents a perspective view
of my apparatus attached to an ordinary dressing glass. The standard on which the
glass is balanced is shown at A, and B represents the frame of the glass. The
plate C is attached to the standard A and is also shown at Fig. 2. The plate D which is
fastened to the glass frame B is also shown at Fig. 3 and centres on the pin E which
enters the hole or socket F (Fig. 3.) on this pin and socket the glass is centred and
balanced.
The screw Fig. 4 is tapped into the hole G on the plate Cand is for the purpose
of pressing the two plates C and D together and is accompanied by a washer Fig. 5.
When the screw (which slides freely in the slot H. H) is tightened it presses the two
plates C and D together thus forming a kind of break so that the glass may be held
in position yet be easily moved to any angle at discretion. When the glass is moved
it is the plate D which revolves the pin & plate C & the screw and washer remaining
stationary. Instead of the washer Fig. 5 a plate as Fig. 6 may be employed. The
hole or socket N fits on the pin E after the pin has passed through the plate D. The
hole K is for the screw to pass through & corresponds with the hole in the washer Fig. 5.
The form and shape of the plate D may be altered and modified for its employment in
connection with the plate Fig. 6. The washer Fig. 5 may be made in section as Fig. 7
so as to fit and slide in the slot H. H. this is to prevent the washer turning with the
screw.
The screw need not be confined to the shape shown at Fig. 4 but may be made with
a countersunk, square, sexagon or other head or a thumbscrew to turn with the fingers
may be used.
Or a tapped pin may be fastened on to plate C to slide in the
slot H H and a loose fly-nut or other nut of any description be employed.
It sometimes happens that a greater distance is required between the standard A
and the glass frame B than is shown at Fig. I. and to make out this distance the
plates and D are thickened or a pin & plate as shown at Fig. 8. is attached to
plate C. On to this pin and plate a washer or collar ornamental or otherwise may be
added. The pin on Fig. 9 to be treated in the same way. The letters S S show
scrow-holes which may be placed in any position on the plates and any number may
be used.

page_text: The plate C instead of being made as Fig. 2. may be shaped as Fig. 12 with a notch
worked on its edge as shown at L. This notch is intended for the tongue m on the
washer Fig. 13 to fit into so as to prevent the washer revolving.
Two of the centerages as above described may be used on a glass or only one may
be employed and a simple pin and socket as shown at Fig. 9 be substituted at the
other end.
The shapes and proportions of the various parts of my invention and their relation
to each other on the drawings herewith are not intended to illustrate the exact form
they shall take but I may modify diminish enlarge or re-arrange them in the manner
most suitable for my purpose.
For instance the pin E may be attached to the plate D instead of the plate C. Or
the plate D be fastened to the standard A and the plate C to the glass frame. Or the
screw may be tapped into the washer or into plate Fig. 6. Or a boss be put to thicken
the hole G on Fig. 2.
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 :-
1stly. The right to make a looking glass centre as shown in the drawings accom-
panying this specification.
2ndly. The right to alter modify diminish enlarge or re-arrange the shapes and
proportions as shown on the drawings accompanying this specification.
3rdly. The right to make the glass centre in any material.
