WILLIAM JOHN HINDE, of No. 31, Oseney Crescent, Camden Road, in the
County of Middlesex, Manager of Cabinet Works. "IMPROVEMENTS IN APPARATUS
FOR SUPPORTING, FIXING, AND ADJUSTING SWING LOOKING GLASSES, SWING
FAN LIGHTS, AND OTHER SWINGING ARTICLES."
My Invention consists of the improvements hereinafter described in apparatus
for supporting, fixing, and adjusting swing looking glasses, swing fan lights, and
other swinging articles.
I will describe my Invention as applied to a swing looking glass. That part of
the apparatus or "movement" which is fixed to the pillar or standard of the swing
looking glass consists of a plate carrying a square or angular axis perpendicular
thereto. The said plate is fixed by screws to the face of the pillar or standard
which carries the glass frame.
The angles of the axis are screwed, and on the end of the said axis is a disc like
head. On the said axis is a washer capable only of a sliding motion thereon.
Situated between the sliding washer and the carrying plate is a binding screw nut
provided with two or with a series of arms, or with a circular rim for turning it.
By turning the said screw nut in one or other direction, the sliding washer may
be pressed towards or allowed to retire from the disc like head on the end of the
axis.
That part of the apparatus which is fixed to the frame of the swing looking
glass consists of a seat or pocket into which the disc like head on the looking glass
pillar is passed by a vertically sliding motion. The said seat or pocket is open,
and has a slot at its bottom or side into which the screwed axis passes.
The inside of the seat or pocket has the same curvature as the disc like head of
the screwed axis, so that the said head is capable of a swinging or partial rotary
motion in the said seat, which is also countersunk.
After the seat or pocket attached to the glass frame has been dropped over the
disc like head attached to the pillar or standard, the binding screw nut is turned
so as to force the washer towards the front of the said seat, and thereby draw the

page_text: head of the axis against the inside of the seat, the said seat being thus gripped
between the said head and washer with any required degree of tightness. The
frictional contact of the said head and washer with the seat is such that the swing
looking glass, while capable of moving through the required angle, is supported
firinly in any position to which it is brought. By tightening or driving home more
or less the binding screw nut, the swing looking glass may be fixed in any required
position. In order to remove the swing looking glass from its standards or uprights,
it is only necessary to relax the pressure of the binding screw nuts upon the
washers, when the latter retire from the seats, and the frame with the scats or
pockets attached can be lifted off the disc like heads attached to the standards or
uprights.
Instead of making the seat with an open bottom or side, the carrying plate may
be furnished with a large circular opening through which the disc like head is
passed preparatory to sliding it into its seat.
I prefer to fix the pocket or seat as nearly as convenient in a line about which
the glass is balanced.
My Invention may be applied to each side of the swing looking glass, or to one
side only. In the latter caso any ordinary axis may be used at one side of the
swing looking glass, and instead of fixing the seat or pocket to the frame of
the glass it may be attached to the pillar, and the disc like head to the frame of
the glass.
Apparatus constructed according to my Invention is very simple in construction
and efficient in action, no cutting away of the wood to fix the apparatus is required,
and there are no detachable parts.
