Improvements in Movements for Suspending and Adjusting Swing
Looking-glasses and other Swinging Frames.
I, CHARLES WEST, of Kenyon Street, in the City of Birmingham, Gas Fitter,
do hereby declare the nature of this invention to be as follows:-
This invention relates to means as herein-after described, for mounting, fixing,
and adjusting swing looking glasses; and which said means, are commonly called
movements, whereby a stiff joint is imparted to the object suspended and hung.
The principal object of my invention, is to simplify the construction of the said
movement, and to render the same more efficient when in use, and without the
liability of a determinate stiffness imparted to the joints, being lessened by wear.
The invention consists essentially in employing upon the middles of the two
opposite edges of the looking glass, pulleys, or fixed wheel-like bosses, encircled by
a metallic friction band, adjusted and kept up to the periphery of the pulley or
fixed boss, by a saddle clip, adapted to embrace the said band, near the upper part
of the pulley or wheel as aforesaid, whilst the connection of the saddle clip, with
the friction band or contact strap, is made by a transversely directed thumb screw,
passing through the shanks or upper parts of them.
In carrying out my invention, I will describe it in connection with a looking
glass, and as the two sides are alike in construction, I will only describe one of
them.
To the middle of the side of the frame of a looking glass, a flanged edged pulley
is rigidly secured, and around the circumferential edge of which, between the
Hanges, a friction band is connected, in manner adapted to embrace the said edge,
and create sufficient friction that the looking glass shall remain in any position, in
which it may have been placed.
The terminal ends of the friction band, are directed upwardly, and take between
the hollow of the bracket of a saddle clip, whose free ends embrace the band, at
points near the upper part of the pulley.
This bracket is secured to the inside face or part of the pillar or upright of
the glass.
To connect the free ends of the friction band to the bracket of the saddle clip,
a thumb screw takes through the bracket, and through holes near the ends of the
clips; or the said ends of the band, may be turned hook-wise, and. the part
immediately near the turn part, made to take within a socket of a separate attach-
ment plate.
It will thus be understood, that the glass is supported through. the intervention
of the pulleys upon its side, by means of a friction band, pressed home by the
springing free ends of a saddle clip, supported and hung from the pillar part of the
glass.
The band instead of being drawn home around the pulley, by the impressive
action of the free ends of the saddle clip, may be adjusted by means of a screw, or
like means.
As a modification, the band may be dispensed with, or may be substituted by
that of a saddle clip, whose free ends are made to pass below the centre of the
pulley of the glass, so as to be thus embraced by a three-quarter clip, which presses
upon the periphery of the pulley, sufficient to create the desired friction, in order
to make a stiff joint.
Instead of the saddle clip being hung downwards, the branches of it, may be
directed upwards, so that the looking glass is supported, instead of being suspended,
as in the previous arrangements

page_text: Looking-glasses provided with movements as described, are self-adjusting when
in use and on wear.
As a further modification, I may direct across the back of the looking-glass, a
bar, and around the ends of it, I pass friction bands, with semi-saddles made to
press upon the outer sides of the said band.

COMPLETE SPECIFICATION.
Improvements in Movements for Suspending and Adjusting Swing
Looking-glasses and other Swinging Frames.
I, CHARLES WEST, of Kenyon Street, in the City of Birmingham, Gas Fitter,
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:-
This invention relates to improvements in means, commonly called movements,
for mounting or supporting swing looking glasses, and swinging frames, for various
purposes, as hereinafter described.
My invention has for its object principally, a movement simple in its construction,
and automatic in its action, which is not liable to disarrangement, or become
inefficient when in use.
The said movement, consists essentially in employing upon the middles of the two
opposite edges of the looking glass, pulleys, or fixed wheel-like bosses, encircled by
metallic friction band, adjusted and kept up to the periphery of the pulley, or
fixed boss, by a pressure saddle-clip, adapted to embrace the said band, near its
upper part.
In carrying out my invention, I will describe it in connection with a looking
glass, and as the two sides are alike in construction, I will only describe one of
them.
To the middle of the side of the frame of a looking glass, a flanged edged pulley
is rigidly secured, and around the circumferential edge of which, (between the
flanges) a friction band clip takes, and is pressed home by a supplementary pressure
clip, of a spring construction, and adapted to press upon the said band clip, in
manner that the same is forcibly pressed upon the pulley edge or boss as aforesaid,
whereby a stiff joint is obtained.
The terminal ends of the band clip, are directed upwardly, and take between
arms of the pressure clip, which is connected to a bracket; or other means of
support.
The band instead of being drawn home around the pulley; by the impressive
action of the free ends of the saddle clip, may be adjusted by means of a screw, or
like means.
As a modification, the band may be dispensed with, or may be substituted by
that of a saddle clip, whose free ends are made to pass beyond tlie middle part of
the pulley.
Looking glasses supported, or provided with such movements, are retained in
any position in which they may be placed, by the pulleys aforesaid working within
the band clips, which are self adjusting on use, and on wear.
Figure 1 of the accompanying drawings, represents in perspective, a swing
looking glass, and accessory stand parts, provided with a pair of friction
movements, constructed and arranged according to my said improvements. The
said movements, are in themselves self-acting, and act in manner alike unto friction
clutches, whereby stiff joints of the parts in contact are made.
Figure 2 represents in front elevation, one of the said movements, upon an

page_text: movement, consists essentially of a metallic band, circumferentially directing
itself around a pulley or drum, and pressed home by a saddle or pressure clutch,
directed preferably upon two opposite sides of the band, and above the middle of
the pulley or drum, while the said appliance is suspended from extensions of the
said band and clutch, and made into a connection, which is adapted to fit or take
within a bracket, secured to the pillars or uprights of the glass, and by means of
which, the said glass, and movements cognate to it are supported.
Figure 3 represents a longitudinal vertical section of the movement Figure 2,
and its pillar, showing how the drum or pulley is affixed to the glass, and how the
band clip surrounds its circumferential edge, or that part, lying between the flanges
of the edges.
Figure 4 represents a vertical section of the movement, upon the dotted
lines A B Figure 2.
Figure 5 is an elevation of the same, with a portion of the glass frame.
Figure 6 is a side elevation of Figure 5;
Figure 7 is a transverse section on the dotted lines CD, Figure 3, and
Figure 8 is an elevation of the bracket, and part of the supporting pillar.
Figures 9, 10 and 11 represent modifications of my invention.
As the movements on both sides of the glass are alike in construction, I will
only describe one of them.
a is a swinging glass, ba drum or pulley, secured to the outer side of the frame
of the said glass, and encircled or circumferentially surrounded by a metallic
friction band c, whose upper ends ², are extended upwardly into suspenders, while
the upper part of the band above the middle of the pulley, is embraced by a half
hoop pressure clutch d, with upwardly directed arms d³, which embrace and
envelope the extensions c² of the band as aforesaid, while the outwardly directed
edges of the upright arms d², are turned at right angles into wing connections,
which take into the undercut recess e², of the attachment bracket e, secured to the
pillar f
The attachment of the movement to the bracket, is made by the passing of the
wing connections, through the open top e³.
A stiff joint is produced, and the glass retained in any position which it may
have been placed, by the resistance offered to the movement consequent upon the
parts being in intimate contact, with yielding pressure applied.
Figure 9 represents another form of my invention. In this arrangement the
band clip is drawn tight around the periphery of the drum or pulley, through
the intervention of a thumb screw, passed through the extension of the band clip,
and pressure clip respectively. The said band and pressure clips, are suspended
and connected in manner alike unto the preceding figures. is a drum or pulley,
secured to the framing of a glass, c is a band clip, with upper extensions c²,
pierced with plain holes c. d is a pressure clip or clutch, adapted to embrace the
said band clip at its upper part as aforesaid, and provided with a screwed hole d³,
through one of the arms d², while the other arm has a plain hole d', and through
which holes d³, d', and c, of both pressure clip and band, a thumb screw h passes,
with the wormed stem 2, screwing into the wormed hole d³, so that by rotating the
said screw, the sides of the pressure clip are brought closer together, and made to
impinge forcibly upon the band clip, whereby the same is pressed against the
periphery of the drum or pulley b, hence a stiff joint.
The drum or pulley is preferably of wood, and if desired, the periphery of same
may be V or taper grooved, wherein a like V shaped part, on the inner side of the
band clip, takes.
Figure 10 represents the movement Figures 2 and 3, inverted, so as to support
instead of to suspend the glass.
Figure 11 represents a further modified form of my invention, showing the
employment of the pressure clip or clutch only, without the band clip, for
acquiring the desired friction between the fixed and moving parts.

page_text: bis the drum or pulley, secured to the frame of glass and embraced circum-
ferentially by a three quarter pressure spring clip d, with upwardly directed
extension arms (2, connected to the pillar f, in manner already described."
Instead of the glass being suspended by the spring pressure clip, as in Figure 11,
the said clip may be inverted, so as to support the glass.
Instead of the band clip and its pressure means being carried by the pillar, they
may be carried by the glass, and the drum or pulley carried by the pillar.
It is understood that two movements are required to each glass, or in some cases,
a glass or swinging frame may be mounted upon a pivot on one side, and be
provided with one movement only on the other side.
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 :-
First: In a swing looking glass or other frame movement, consisting essentially
of a band clip of the one part, circumferentially surrounding a drum, pulley or
equivalent of the other part, whereby a looking glass, or frame as aforesaid, is
mounted and supported, and a stiff joint obtained, substantially as described and
set forth.
Secondly In a swing looking glass or other frame movement, consisting of a
band clip, and spring pressure clip or clutch, of the one part, circumferentially
surrounding and working upon the periphery or edge of a fixed drum or pulley, of
the other part, substantially as, and for the purpose as described and set forth in
Figures 1, 2, 3, 4, 5, 6, 7, 8, and 10.
Thirdly: In a swing glass or frame movement, constructed, arranged, and
combined, with the supporting brackets, as set forth in the same figures as in the
preceding claim.
Fourthly In a swing glass or frame movement, the combination with a fixed
drum or pulley, of the one part, and a circumferential band clip, and spring
pressure clip or clutch, drawn together, by a screw, of the other part, as set forth
in Figure 9.
-
Fifthly In a swing glass or frame movement, consisting of a spring embracing
pressure clip or friction clutch with spring embracing arms, of the one part, and
a fixed pulley or drum, of the other part, as set forth in Figure 11.
