PROVISIONAL SPECIFICATION.
An Improved Swing Joint or Movement for Mirrors, Windows,
Ventilators, Book-rests, and other Swinging Articles.
We, HENRY ALEXANDER SQUIRE and JAMES EDMUND ALLDRITT SQUIRE,
trading together as Henry Squire & Sons, of New Invention, near Wolverhampton,
in the County of Stafford, Manufacturers and Brass Founders, do hereby declare
the nature of this invention to be as follows:-
-
This invention consists of the herein described improved swing joint or move-
ment for mirrors, windows, ventilators, book-rests, and other swinging articles.
The said swing joints as usually constructed are liable to wear and then the
swinging mirror or other article with which the joint is used cannot be pro-
perly retained by the joint at any desired angle. Our invention is so con-
structed that the parts are not liable to wear and thus the joint or movement
will securely hold at any desired angle the mirror or other article with which
it is used and at the same time allow of the mirror or other swinging article
being readily removed from its supports when required and readily replaced.
We will describe this invention as applied to a swinging mirror.
In carrying out this invention we provide a metal plate which by screws or
other means is fixed to the side of the mirror. Working against the face of
this plate is a metal disc which is secured to the plate by a central pivot pin
passing through the centre of the same and through the disc. The rounded
head of a spring pin or catch projects from the face of the plate and engages
with any one of a series of holes or notches formed in a circle round the face
of the disc. The plate is made with a hollow boss to receive the said pin and
the coiled wire or other spring which operates the pin. The head of the pivot
pin which secures the disc and the plate together is made of a taper dove-
tailed shape, smaller at the lower side than at the top, so as to engage with the
corresponding usual dovetailed slot which is formed to the stationary part of
the movement which is fixed to the stand.
It will be understood that our invention as above described is applied to both
sides of the swinging mirror and stand. When the mirror is turned about the
pivots the head of the spring pin or catch engages with one or other of the holes
or notches in the face of the disc and thus secures the looking-glass in an up-
right position or at the desired angle. When it is desired to remove the look-
ing-glass from the stand this is done in the usual way by simply lifting the
looking-glass so that the pivot pin heads rise up out of the stationary parts of
the movement which are fixed to the stand.
The improved swing joint or movement above described is or may be pro-
vided with a catch or other suitable device to prevent the dovetailed headed
pivot pin and parts fixed thereto from working out of the dovetailed stationary
part of the movement which
fixed to the stand.

We, HENRY ALEXANDER SQUIRE and JAMES EDMUND ALLDRITT Squire,
trading together as Henry Squire & Sons,.of New Invention, near Wolverhampton,
in the County of Stafford, Manufacturers and Brass Founders, 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 consists of the herein described improved swing joint or move-
ment for mirrors,' windows, ventilators, book-rests, and other swinging articles.
The said swing joints as usually constructed are liable to wear and then the
swinging mirror or other article with which the joint is used cannot be pro-
perly retained by the joint at any desired angle. Our invention is so con-
structed that the parts are not liable to wear and thus the joint or movement
will securely hold at any desired angle the mirror or other article with which
it is used and at the same time allow of the mirror or other swinging article
being readily removed from its supports when required and readily replaced.
We will describe this invention as applied to a swinging mirror and refer to
the accompanying drawings on which Fig. 1 is a front elevation of our im-
proved swing joint or movement and Fig. 2 is a front elevation of the ordinary
dovetailed slotted stationary part which is fixed to the stand; Fig. 3 is a sec-
tional elevation of the parts shewn by Figs. 1 and 2; Fig. 4 shews the separate
parts of which our invention illustrated in Figs. 1 and 3 is formed; Fig. 5
is a front elevation partly in section and Fig. 6 is a side elevation of a modi-
fication of our invention and Fig. 7 shews the separate parts of which the modi-
fication represented in Figs. 5 and 6 is formed.
-
The sanie letters of reference indicate the same or corresponding parts in all
the figures. We will first describe the arrangement illustrated by Figures 1
io 4 inclusive.
'
In carrying out this invention we provide a metal plate A which by screws
passing through the holes a¹ a² is fixed to the side of the mirror. Working
against the face of this plate A is the metal disc B which is secured to the
plate A by a central pivot pin C passing through the central hole a³ of the
plate A and also through the hole 61 of the disc B. The part cl
of the pivot pin C and the hole in the disc B are made square
or other shape than round so that the plate B and pin C will
turn together. The head of the pivot pin C is made of a taper dovė-
tailed shape as shewn smaller at the lower side than at the top so as to engage
with the corresponding slot which is formed in the ordinary stationary part D
of the movement which is fixed to the mirror stand. The back end of the
pivot pin C is rivetted over a washer g at the back of the plate A so as to secure
the parts together but allow of the pin C turning in the plate. The rounded
head e of a spring pin or catch E projects from the face of the plate A and
engages with any one of a series of holes or notches 62 formed in an arc of a
circle round the back face of the disc B. The plate A is made with a hollow
boss a to receive the spring pin E and the coiled wire or other spring f which
acts between the head e¹ of the pin and the interior end of the boss a¹ so as to
press the pin E forward to engage with one or other of the notches 62 as afore-
said.
It will be understood that our invention above described is applied to both
sides of the swinging mirror and stand. When the mirror is turned about

page_text: the pivots C the head e¹ of the spring pin or catch E engages with one or other
of the holes or notches 62 in the face of the disc B and thus secures the looking
glass in the desired position.
When it is desired to remove the looking glass from the stand this is done in
the usual way by simply lifting the looking glass so that the pivot pin heads
rise up out of the stationary parts D of the movement which are fixed to the
stand.
Instead of the spring pin E being arranged to engage with notches formed
in the face of the disc B as in the arrangement above described, the said spring
pin E may, as in the arrangement illustrated by Figs. 5, 6 and 7, be arranged
to engage with notches 6 formed round the upper part of the periphery of the
disc B. In this case the hollow boss at in which the spring pin E is contained
and works is formed on the front of the plate A immediately above the disc B
and the head e¹ of the pin E projects through a hole in the bottom of the boss
so as to engage with any one or other of the notches 64 in the disc B when
the latter is turned.
The disc B has two lateral projections 63 one at each side arranged as shewn
so that when the looking glass has been turned to its extreme position in either
direction one or other of these projections 63 will come in contact with the
projection a in Figs. 5, 6 and 7, or with the projection a³ in Figs. 1, 3 and 4
formed on the face of the plate A and thus form stops to prevent the swinging
mirror from being turned too far.
. Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:
In a swing joint or movement for mirrors, windows, ventilators, book rests
and other swinging articles, the combination of the plate A adapted to be fixed
to the side of the mirror or other swinging article, the disc B adapted to turn
on the face of the plate A, the pivot pin C turning with the disc and securing
the plate and disc together and provided with the taper dovetailed head to
engage in a slot in the stationary part D of the movement, the spring pin or
catch E contained in a boss of the plate A and adapted to engage with one or
other of a series of holes or notches formed in the disc and thus secure the
swinging mirror or other swinging article in the desired position, all substan-
tially as set forth.
