WILLIAM JOHN HINDE of No 31 Oseney Crescent, Camden Road, in the County
of Middlesex, Manager of Cabinet Works. "IMPROVEMENTS IN APPARATUS FOR
SUPPORTING AND FIXING SWING LOOKING GLASSES, SWING VENTILATORS AND OTHER
SWINGING ARTICLES
"
My Invention consists of the construction and combination of parts herein after
described of apparatus for supporting and fixing swing looking glasses, swing
ventilators and other swinging articles.
By my Invention the connection of the swing looking glass and other like
article with and its disconnection from the standards or uprights in which it is
supported and turns, are effected with great facility and the swing glass or article
is held firmly in any position to which it may have been adjusted.
I will describe my invention as applied to a swing looking glass. To the side of
the frame of the swing looking glass, I fix an axis on which the glass turns the
said axis being provided with a disc like head. The central portion of the inner
face of this head is cut away so as to leave the peripheral portion of the original
thickness, the uncut away part constituting a cylindrical rim. In the said rim is a
slot for the purpose herein after explained.
The bearing or support, which is fixed on the standard or upright of the swing
looking glass, consists of a plate carrying a slotted bracket parallel to the said
plate, the space between the bracket and plate being of a width somewhat greater
than that of the head of the axis fixed to the swing glass. On the inner face of
the bearing plate is a strong bow spring and on the inner face of the slotted
bracket is a pin or stud of a size suitable to pass through the slot in the rim of the
head of the axis.
In connecting the swing glass to its uprights or standards the swing glass is
inverted so as to bring the slot in the rim of the head opposite the stud on the
bracket fixed to the supright [sic].
The swing glass being lowered the head of the axis enters between the bearing
plate and bracket, compressing the bow spring, the axis at the same time passing
into the slot in the bracket. On the rim of the head of the axis meeting the
bottom of the bracket, the slot in the said rim of the head of the axis passes over
the pin or stud on the slotted bracket, and by giving the swing glass a semi-
rotation the said rim of the head engages with the pin or stud and the swing glass
is secured to the upright. By the binding action of the compressed bow spring
the head of the axis is forcibly pressed against the slotted bracket, the friction
between the said parts maintaining the swing glass in the position to which it
may have been adjusted. In order to remove the swing glass from its uprights it
is only necessary to invert the said glass so as to bring the slot in the rim of the:
head opposite the stud on the slotted bracket, when the said head may be lifted
from the bearing plate and the swing glass detached from the uprights.
The swing glass may be connected with the uprights in a horizontal position, the
glass in taking its normal position causing the rim on the head of the axis to
engage with the stud or pin on the bracket and secure the glass in its place; and
instead of a bow spring pressing the head of the axis against the slotted bracket, an

page_text: A
India rubber or other spring at the bottom of the bearing plate may be made to
press the rim of the head forcibly against the pin or stud on the bracket so as to
bind the parts together and exert frictional contact upon the said head.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in side elevation and Figure 2 the same partly in vertical
section, a portion of a swing looking glass containing supporting and fixing
apparatus constructed according to my invention, Figures 3 and 4 represent partly
in front elevation and partly in vertical section a portion of the upright and
looking glass, together with the apparatus, the sectional parts being taken in a
plane at right angles to that in which the section of Figure 2 is taken. In
Figure 3 the looking glass is represented in the act of being fixed to the upright
and in Figure 4 after it has been fixed to the upright, Figure 5, represents a side
elevation of the two parts of the apparatus detached, Figure 6 represents a vertical
section of the same and Figure 7 represents a front elevation of the same. The
same letters of reference indicate the same parts in Figures 1. 2. 3. 4. 5. 6 and 7.
As the apparatus at opposite sides of the swing looking glass is alike in
construction and action, I have only represented the apparatus applied to one side
of the looking glass.
a. is the swing looking glass and b is one of the uprights or standards. To the
outer side of the frame of the looking glass a, the axis c. is fixed on which the
glass turns, the said axis c having a disc like head d with a cylindrical rim d³.
In the said rim d. is a slot d³. for the purpose herein after described; e is the
bearing or support which is fixed on the standard or upright b of the swing
looking glass. The said bearing e consists of a box or case with a fixing back
plate, the front plate of the said bearing having a vertical slot f, in it for
receiving the axis c. on the swing glass. Instead of the box or case of the
bearing having closed sides as represented, it may be open at its sides, thus con-
stituting a bracket. On the inner face of the back plate of the bearing e, a strong
bow spring g is fixed and on the inner face of the slotted front plate of the bearing
and immediately below the slot g, is a pin or stud h, of a size suitable to pass
through the slot d³. in the cylindrical rim d. of the head of the axis c.
In securing the swing glass a to its upright or standard 6 by the use of the
apparatus described, the swing glass a is placed (by preference) in a horizontal
position so as to bring the slot d³ in the cylindrical rim d². into its lowest position
and over the fixed stud h on the bearing e. The swing glass being now lowered
in the position indicated, the head d of the axis c, enters the box or case of the
bearing e, thereby compressing the bow spring, g the axis cat the same time passing
into the slot in the front plate of the bearing. On the rim d. of the head d.
reaching the bottom of the bearing, the slot d³, of the said rim passes over the pin
or stud h as illustrated in Figure 3. By now giving the swing glass a. a motion
through a quadrant so as to bring it into a vertical position, the said rim d².
engages with the pin or stud h, as illustrated in Figures 2 and 4, thereby securing
the swing glass in its supports. That is to say, the pin or stud engaging with
the rim d² prevents the lifting of the glass from the uprights, but permits of the
rolling of the rim d². carried by the glass upon the pin when the glass is partly
rotated for adjusting its position, the binding action of the compressed bow spring g
upon the head & maintaining the swing glass in the position to which it has been
adjusted.
When it is desired to remove the swing glass a. from its uprights, the said glass
is turned into a horizontal position, thereby bringing the slot d³. in the cylindrical
rim opposite the pin or stud h, on the fixed bearing e. when the said glass may
be lifted vertically and removed from the uprights as will be understood by an
examination of Figure 3.
Instead of arranging the bow spring at the back of the box of the fixed bearing e.

page_text: it may be arranged at the front of the said box, the pin or stud with which the
cylindrical rim of the head engages being in this case situated at the back of the
box of the bearing.
This modification is illustrated in section in Figure 8 and parts separately in
Figure 9. In this modification the bow spring 9. is forked and the slotted front
plate e² of the bearing is extended downwards and between it and the back plate e.
of the bearing one end of the bow spring is fixed by the rivetting of the two
plates e. e. together. The cylindrical rin d. is made on the outer face of the
head d. so that it may engage with the pin or stud h. on the back plate e. (see
Figure 8). The action of this modification of my invention is essentially the same
as that first described, the frictional contact of the bow spring 3 being upon the
inner face of the head of the axis instead of upon the outer face of the said head,
the bow spring g in Figure 8 drawing the glass towards the upright, and the
bow spring in Figures 1. 2. 3 and 4 pressing the glass from the upright.
Figure 10 represents, in side elevation and Figure 11 in section a modification
of my invention in which the bow spring g is dispensed with; Figure 12 represents
a section of the apparatus taken in a plane at right angles to that in which the
section Figure 11 is taken and Figure 13 represents the parts of the apparatus
separately.
In this modification a piece or block of leather, india rubber or other elastic or
yielding material i is placed at the bottom of the hollow bearing e fixed on the
upright b. When the swing glass a. is secured in its place in the upright b. in the
manner herein before described, the weight of the said glass acting through the
rim d² of the head slightly compresses the india rubber or other yielding material i
which tends to press the said rim forcibly against the pin or stud / on the bearing e.
the frictional contact of the said india rubber or material i. with the rim d*.
maintaining the looking glass in the position to which it has beon adjusted.
To increase the bite or hold of the india rubber or material upon the rim d², the
outside of the said rim is by preference grooved or milled as seen in Figure 13.
The parts of this modified apparatus which I have not described are the same as
those already described and corresponding parts are marked with the same letters
of reference.
I apply my invention to swing ventilators, and other swinging articles substan-
tially in the manner herein before described and illustrated with respect to a swing
looking glass.
Having now described the nature of my Invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my invention
of "Improvements in apparatus for supporting and fixing swing looking glasses,
'swing ventilators and other swinging articles
"
First. The construction and combination of parts herein before described and
illustrated in the accompanying Drawings for connecting the swing looking glass
or other swinging article to and removing it from the uprights standards or
Eupports in which the said glass or article turns; that is to say; the construction of
the slotted rim d². d. on the disc like head of the supporting axis of the swing
looking glass or swinging article and the combination there with of the fixed stud
or pin on the bearing or support e, or e, e², for the purpose and substantially as
described and illustrated.
Secondly. The construction and combination of parts herein before described
and illustrated in the accompanying Drawings for maintaining the swing looking
glass or other swinging article in the position to which it has been adjusted; that
is to say, by means of the bow spring y in the pocket case or box of the support or
bearing pressing against the face of the disc like head of the supporting axis as
described and illustrated.
Thirdly. The modification described and illustrated in Figures 10 to 13 of the
accompanying Drawings in which the outer edge of the disc like head of the axis
