We, PHINEHAS EDWARD AYTON of the Firm of Thomas Pemberton and Sons of
Livery Street, Birmingham, in the County of Warwick Manufacturer and JOHN
PEARSON of Barford Road, Birmingham, aforesaid, Brassfounder, do hereby declare
the nature of said invention for "IMPROVEMENTS IN MOVEMENTS FOR SWING
LOOKING GLASSES, FANLIGHTS AND FOR SUCH LIKE OBJECTS," to be as follows:-
Our invention relates to appliances or means whereby a stiff or tight joint is
obtained which said appliances are commonly called glass movements employed for
suspending or supporting swing looking glasses and the like, such as for example,
fanlights, ventilators, banner screen arms and other like objects which are required
to be retained in any desired position to which they may have been placed.
We will describe our invention as applied to a swing looking glass, and as the
two movements or joints are alike in construction, we will only describe one
of them.
Our invention has reference to those kinds of joints which are commonly known
as Cope's movement; and our said invention consists in dispensing with the
ordinary binge joint, and substituting therefor, a socket, or short cylinder closed at
one end, and let into the pillar of the glass; and attached by ears. The said socket
is gapped or slotted longitudinally upon one side, so as to admit the stem or neck
of the other part of the movement. The closed end of the socket is formed into a
hemispherical head wherein the said head seats itself. The mouth of the socket is
internally wormed, wherein a screw plug or shank takes, having at its front end a
dished or spherical seat which bears upon the surface of the spherical head as
hereinafter described. The screw plug or shank is rotated by a fly turn or thumb
bit, or by a slotted or vice handle which is capable of moving or sliding upon the
end of the stem, so that the handle or turn can be moved so as to obtain greater
leverage, or be moved from one position to another in screwing up the plug to
clear the frame or pillar of the glass, as the case may be. The other part of the
movement consists of a spherical head on the end of a neck or stem fixed to an
attachment plate which is affixed to the frame of the glass by screws.
In using the movement, when the two parts are connected respectively to the
glass frame and pillar, the spherical head on the one part lies within the hollow of

page_text: the socket on the other part with the neck of the said head lying transversely
across the slot or opening and the head seating itself within the hemispherical
closed end. By screwing the plug into the mouth of the socket until its end
presses forcibly upon the spherical head, when the said head is pressed to its seat
and can only move or rotate between the closed end of the socket and the dished
end of the screw plug (which is provided with a fly turn or other means for forcing
it home) thereby producing a stiff or tight joint, which allows the glass to which
the movement is attached, to rest or remain in any desired position to which it may
have been placed.
As the parts wear or become loose by use, it is only necessary to rotate the plug,
when the desired binding or stiffness is made between the moving and fixed parts.
When the parts are required to be disconnected for transit, it is only necessary
to withdraw the screw plug from the socket or short barrel, when the parts can
be separated.

We, PHINEHAS EDWARD AYTON of the Firm of Thomas Pemberton and Sons of
Livery Street Birmingham in the County of Warwick Manufacturer, and JOHN
PEARSON of Barford Road Birmingham, aforesaid, Brass-founder, do hereby declare
the nature of said invention for "IMPROVEMENTS IN MOVEMENTS FOR SWING
LOOKING GLASSES, FANLIGHTS AND FOR SUCH LIKE OBJECTS," and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
Our invention relates to appliances or means whereby a stiff or tight joint is
obtained, which said appliances are commonly called glass movements, employed or
used for suspending or supporting swing looking glasses and the like, such for
example, as fanlights, ventilators, banner screen arms and other like objects which
are required to be retained in any desired position to which they may have been
placed.
We will describe our invention as applied to a swing looking glass, and as the
two movements or joints are alike in construction, we will only describe one
of them.
Our invention has reference. to those kinds of joints which are commonly known
as Cope's or sphere head movements; and our said invention consists in dispensing
with the ordinary hinge joint, and substituting therefor, a socket or short cylinder
closed at one end, and let into the pillar of the glass; and attached thereto by ears.
The said socket is gapped or slotted longitudinally upon one side, so as to admit

is formed into a hemispherical seat corresponding to the spherical head wherein the
said head seats itself. The mouth of the socket is internally wormed, wherein a
screw plug or shank takes, having at its front end a dished or hemispherical seat,
which bears upon the surface of the spherical head as hereinafter described. The
screw plug or shank is rotated by a fly turn or thumb bit; or by a slotted or vice
handle, which is capable of moving or sliding upon the end of the stem, so that the
handle or turn can be moved, so as to obtain greater leverage, or be moved from
one position to another, either in screwing up the plug, or to clear the frame or pillar
of the glass, as the case may be. The other part of the movement consists of a
spherical head on the end of a neck or stem fixed to an attachment plate which is
affixed to the frame of the glass by screws.
In using the movement, when the two parts are connected respectively to the
glass frame and pillar, the spherical head on the one part lies within the hollow of
the socket on the other part, with the neck of the said head lying transversely
across the slot or opening, and the head seating itself within the hemispherical
closed end. By, screwing the plug into the mouth of the socket until its end presses

only move or rotate between the closed end of the socket, and the dished end o
the screw plug, (which is provided with a fly turn' or other means for forcing i
home) thereby producing a stiff or tight joint by the friction thus created, which
allows the glass to which the movement is attached, to rest or remain in any desired
position to which it may have been placed.
As the parts wear or become loose by use, it is only necessary to rotate the plug
forward, when the desired binding or stiffness is made between the moving and
fixed parts.
When the parts are required to be disconnected for transit, it is only necessary
to withdraw the screw plug from the socket or short barrel, when the parts can
be separated.
We will now proceed to describe with reference to the accompanying Drawing
the manner in which the same is to be performed.
Figure 1 represents in back elevation, a swing glass movement constructed
according to our invention. Figure 2 is a transverse vertical section of the same,
on the dotted lines A B figure 1, looking towards the side of the pillar of the glass
that is, that portion of the movement which is attached to the pillar; the section
being taken through the suspending spindle. Figure 3 is a horizontal section on
the dotted lines CD figure 1 with the binding plug or expedient screwed home.
Figure 4 represents the plug removed from the socket, in order to admit of the
removal of that portion of the movement carried by the glass; the latter of which
is represented in elevation and plan in figures 5 and 6.
The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
a is a close ended socket or short cylinder, let into the pillar or support of a
swing looking glass, and affixed or secured thereto by attachment ears a² a². The
closed end of the socket is provided with a hemispherical seat a³, wherein the
spherical head c on the other part of the movement seats itself. a is a longitudinal
slot or opening, situated on the inside part of the said socket, as best seen in
figures 2 and 4. This side opening is for the purpose of allowing the stem or
neck c² of the spherical head c to pass into position, on the parts of the movements
being put together.
The seat on the bottom of the closed end is preferably of the same curvature as
the spherical head.
The bore of the socket is internally wormed with a screw thread a', and within
the said bore part, a screw plug d takes, having upon its front end, a dished or
hemispherical seat d², which said seat bears upon the surface of the spherical head c.
The screw plug d is rotated or turned by a fly turn or thumb bit d³. The glass
part of the movement is attached to the frame e by the bracket c³..
The pillar upon which the fixed side of the movement is attached is marked f
On the parts of the movement being put together; as represented in figuro 3, so
that the spherical head on the one part lies within the socket or hollow of the other
part, with the neck of the said head lying transversely across the slot. or gapped
opening, which admits of the passage of the head to its seat.
By now screwing home the screw plug d, the spherical head is enclosed between
the curved seating a³ of the socket a, and the hollowed part d' on the forepart of
the plug; thereby producing a stiff or tight joint, and the friction thus created,
allows a swing glass to rest or remain in any desired position to which it may
have been placed.
As the parts become worn by use, it is only necessary to rotate the plug in a
forward. direction, when the desired stiffness is created between the fixed and
moving parts.
When the parts are required to be disconnected for transit, it is only necessary
to withdraw the screw plug d from the internally wormed socket. as shown at
figure 4, when the glass can be removed from the supporting pillars..

leverage is required for the screwing up of the binding expedient.
dis the stem of the screw plug d, and g is a link or handle, capable of sliding
like a vice handle. This allows the said handle to be moved to one or the other
side of the pin g' so as to obtain greater leverage on the screwing up of the binding
expedient; but when the handle is not required to be used, it is made to slide on
one side, so as to be out of the way of the glass.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is
First. Swing-looking glass, fanlight and other like movements, consisting of an
internally screwed socket or short barrel (of the one part) having a concaved or
dished seating at its closed or bottom end; and within the open end of the said
socket or barrel, a screw plug with a concaved seating at its forward or front end
takes; and which said plug is made to advance forward, or retire, on being rotated;
and between the bottom or closed end of the said socket or barrel, and the concaved
forward end of the plug, a spherical head on the end of an axis of the other part of
the movement takes and works. The spherical head being introduced within, or
withdrawn from the socket, by means of a slotted or gapped side, through which
the neck or axis carrying the spherical head passes; substantially as described and
illustrated.
Secondly. Making the handles or turns, by which glass and other like move-
ments are screwed up, movable, or vice like; substantially as and for the purpose
herein described in figure 7.
