Improvements applicable to Swing Dressing-glass Frames and
similarly Suspended Articles,
I, THOMAS HARGREAVES BRIGG, of Bradford, Yorkshire, Manufacturer, 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 applicable to swing dressing or looking
glass frames and other similarly suspended articles, its object being to permit of such,
articles being readily set and to cause them to be automatically maintained in any
desired position suitable to or as desired by the user, and to attain such object by the
use of means which will avoid the disadvantages attendant upon the means usually
employed with the object of securing the article in the position in which it may
be set.
In the commoner varieties of swing glass frames or other similarly suspended
articles, the fixation thereof is ordinarily effected by thumb-screws inserted through
the side supports of the glass and screwing into the sides of the swing frame. This
method is disadvantageous in that by frequent use the screws and parts with which
they engage get quickly worn, and resort is had to plugging the enlarged holes and
other unsatisfactory ways of causing the desired fitting of the parts, but usually
with an unsatisfactory effect. In other methods various devices are applied to the
trunnions or pivots projecting from the swing frame or from the supporting standards
and from which the swing frame depends and upon which it swings, with the object
of more or less tightly nipping the same between opposite parts so as to obtain the
desired frictional hold, but in consequence of the relatively large leverage of the swing
frame and of its constant tendency to assume a vertical position, a much greater nip
has to be given by such devices to render them effective than can conveniently be
given by hand, and access has to be obtained to the back of the swing frame in order
that the device may be conveniently operated, and they are consequently of comparatively
little use and require constant alteration.
The improved device consists essentially of frictionally engaging parts respectively
pivotally attached to the top, upper or other convenient part of the swing frame and
to some convenient part of the supporting frame.
On the accompanying drawings,
Fig. 1, represents, in side elevation, a swing frame adapted with an embodiment of
the present improvements.
Fig. 2 represents a back elevation thereof.

Fig. represents a vertical section through the frictionally engaging parts.
Fig. represents a transverse section thereof, and
Fig. 5 represents a modification.
In the modification of the improved apparatus represented in Figs. 1 to 4 on the
accompanying drawings the frictional contact of the parts is effected by forming one
thereof as a rod 5, and the other thereof as a surrounding tube 6, split, as at 7, in
that portion of its length which engages with the rod 5, and slightly sprung or
distended so as to more or less automatically grip the rod when inserted therein.
The part 5 is pivotally attached to the swing frame 11 as at 12, and the part 6 is
pivotally attached to the supporting frame 13, as at 14, or in any other equivalent
manner. 15 represents the pivots upon which the frame 11 turns.
If the parts of the split tube do not possess sufficient resiliency to give the necessary
frictional contact to prevent slipping of the parts occasioned solely by the aforesaid
tendency of the glass to assume a vertical position, the split tube may be surrounded
by a movable split metal ring or by equivalent means of causing any required additional

page_text: formed or fitted with a surrounding grooved enlargement 8, adapted to receive a rubber
ring 9, or a split metal ring. The rod may be made of a circular, angular, flat,
corrugated or other suitable section, and the surrounding tube or other equivalent
adjacent part having frictional contact there with may be of a corresponding differential
formation.
As a further modification each of such parts 5-6 may be made with a frictionally
holding part 10, adapted to engage with the other of such parts so as in the same
appliance to duplicate the frictional holding parts vide Fig. 5.
The device may be made in metal, wood or any other suitable material.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what 1
claim is.
A device applicable to swing dressing or looking glass frames and other similarly
suspended articles to permit of such articles being readily set and to cause them to be
automatically maintained in any desired position, consisting of frictionally engaging
parts respectively pivotally attached to the top, upper or other convenient part of the
swing frame, and to some convenient part of the supporting frame, substantially as
herein before described.
