Improvements in Swing Looking Glass Pivots and Adjusters.
I, MARSHALL ROBINSON, of 3, Kingsley Road, Walthamstow, in the County of
Essex, Manager of Cabinet Factory, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improved means for supporting swing looking glasses
and for adjusting the angular positions of the same.
According to my invention 1 make each of the pivot plates, which is attached
to the swinging frame, with two pins and I construct each of the bearings, which
is attached to the usual fixed standards or frame, with substantially vertical
and horizontal slots in which the two pins on the pivot plate respectively slide,
the pin on the pivot plate which slides in the horizontal slot, and which when
the said plate is fixed in position should be at the centre of gravity of the swing-
ing frame, serving as the pivot proper whilst the other pin which slides in the
vertical slot serves as a guide or steadying pin.
With this arrangement as the angle of the glass is altered the pivot pin proper
simply slides more or less in the horizontal slot the weight of the glass retaining
the same in position with sufficient rigidity.
In practice the vertical and horizontal slots in the bearing bracket are in
communication so that when the two pins are in line with the vertical slot the
glass can be lifted out of the bearings.
It will be understood that with my invention there are no clamping parts or
screws which are liable to get out of order whilst at the same time the glass can
always be readily moved and will remain in any position in which it is placed.

Improvements in Swing Looking Glass Pivots and Adjusters.
I, MARSHALL ROBINSON, of 3, Kingsley Road, Walthamstow, in the County of
Essex, Manager of Cabinet Factory, 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 improved means for supporting swing looking-glasses
and for adjusting the angular positions of the same.

page_text: According to my invention I make each of the pivot plates, which is attached
to the swinging frame, with two pins and I construct each of the bearings, which
are attached to the usual fixed standards or frame, with substantially vertical
and horizontal slots in which the two pins on the pivot plate respectively slide;
the pin on the pivot plate which slides in the horizontal slot, and which when
the said plate is fixed on the frame is advantageously in such a position that a
horizontal line drawn through it passes through the centre of gravity of the
swinging frame, serves as the pivot proper whilst the other pin, which slides in
the vertical slot, serves as a guide or steadying pin.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which:
Figures 1 and 2 are elevations at right angles to one another of the pivot plate
of one of my improved devices for supporting swing looking-glasses and for
adjusting the angular positions of the same; and,
Figure 3 is a plan of the same.
Figures 4 and 5 are elevations at right angles to one another of the bearing
of the said device; and,
Figure 6 is a plan of the same; and
Figures 7 and 8 are respectively a side elevation and a front elevation of part
of one side of a swing looking-glass with one of my improved devices applied
thereto.
a is the pivot plate attached by screws or the like to the swinging frame c of
the looking-glass and d, e are the two pins thereon, the said plate, together with
the one on the other side of the frame, being in such a position that a horizontal
line drawn through the pins e on the said plates passes through the centre of
gravity of the looking-glass.
f
the bearing attached by screws g or the like to the looking-glass standard h
and i, are the vertical and horizontal slots therein with which engage the
pins d and e respectively of the pivot plate, the said slots and being advan-
tageously of T-shape and trough shape respectively, and the pin d also of a
T-shape to correspond and engage with the slot
the horizontal
slot may be corrugated or provided with teeth or the like if found desirable.
With this arrangement, as the inclination of the glass is altered the pivot
pins e at each side thereof simply slide in the horizontal slots j and the pins d
in the vertical slots i, the weight of the glass retaining the same in position with
sufficient rigidity.
By making the slots trough shaped it will be seen that the glass can be lifted
out of the bearings in any position it may be in.
It will be clear that with my invention clamping parts or screws which are
liable to get out of order are dispensed with whilst at the same time the glass
can always be readily moved and will remain in any position in which it is placed.
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:-
1. A device for supporting swing looking-glasses and for adjusting the augu-
lar positions thereof consisting of a fixed bearing and a pivot plate adapted to
slide relatively therewith in vertical and horizontal planes, substantally as herein-
before described.
2. A device for supporting swing looking-glasses and for adjusting the angular
positions of the same, comprising a pivot plate designed to be attached to the
frame of the glass and having two pins thereon and a bearing adapted to be
attached to a standard and having a vertical and a horizontal slot with which
the pins on the pivot plate respectively engage, substantially as described.
3. A device for supporting swing looking-glasses and for adjusting the angular
positions of the same, comprising a pivot plate designed to be attached to the
frame of the glass and having two pins thereon, one of which is T-shaped and the

page_text: other plain and a bearing adapted to be attached to a standard and having a
vertical T-shaped slot and a horizontal trough-shaped slot to engage with the
T-shaped and plain pins respectively of the pivot plate, substantially as described.
4. The improved device for supporting swing looking-glasses and for adjusting.
the angular positions of the same, hereinbefore described and illustrated in the
accompanying drawing.
