PROVISIONAL SPECIFICATION.
An Improved Movement for Swing Looking-glasses and the like.
We JOSEPH COOKE, WILLIAM EDWARD COOKE and ROBERT WOLSTEN-
HOLME COOKE, trading as Cooke Brothers, of 65A, Constitution Hill, Birmingham,
in the County of Warwick, Engineers, and HENRY SHAW, of Witton Road, Aston,
also in the County of Warwick, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in movements for swing looking-glasses
and the like whereby the latter can be adjusted and retained at any required angle
without the use of a screw or rack.
In carrying out our invention we provide a slotted plate or link adapted to be
pivotally connected to the looking-glass frame or to one of the standards supporting
the same and a stud passing through the slot in the said plate and provided with
a spring in such a manner that the head of the said stud will be in frictional
contact with the plate, the said stud being arranged in conjunction with a
plate adapted to be attached to the looking-glass frame if the slotted plate is
connected to the standard or to the standard if the slotted plate is connected to
the frame.
We sometimes arrange in conjunction with this frictional adjusting device means
for suspending the glass between its standards. For this purpose we form upon
the plate provided with the stud an aperture or socket designed to receive a
T-shaped or other pivot.

COMPLETE SPECIFICATION.
An Improved Movement for Swing Looking-glasses and the like.
We, JOSEPH COOKE, WILLIAM EDWARD COOKE and ROBERT WOLSTEN-
HOLME COOKE, trading as Cooke Brothers, of 135-145A, Constitution Hill,
Birmingham, in the County of Warwick, Engineers, and HENRY SHAW, of
Witton Road, Aston, also in the County of Warwick, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :—
This invention relates to improvements in movements for swing looking-glasses
and the like whereby the latter can be adjusted and retained at any required angle
without the use of a screw or rack.
In carrying out our invention we provide a slotted plate or link adapted to be
pivotally connected to the looking-glass frame or to one of the standards supporting
the same and a stud passing through the slot in the said plate and provided with
a spring in such a manner that the head of the said stud will be in frictional
contact with the plate, the said stud being arranged in conjunction with a plate
adapted to be attached to the looking-glass frame if the slotted plate is con-
nected to the standard or to the standard if the slotted plate is connected to
the frame.
In conjunction with this frictional adjusting device we sometimes provide special
means for suspending the glass between its standards, that is to say, we form upon
the plate provided with the stud a T-shaped or other pivot adapted to enter an

page_text: Figure 5 is a plan of the same :
Figure 6 is a face view of the other part of the means of suspension; and,
Figure 7 an edge view of the same:
Figures 8 and 9 are similar views to Figures 3 and 4 but illustrating the
movement when applied to a swing looking-glass provided with ordinary means
of suspension.
Similar letters in all the figures indicate similar parts.
a, Figures 1 and 2, is part of the frame, and part of one of the standards of a
swing looking-glass.
c, Figures 1 to 4, is the slotted plate or link of our movement, which plate or
link we connect to the looking-glass standard b (or to the frame a) by a pivot such
as d; e is the stud which passes through the slot f in the plate c and through a
plate g fixed in a recess in the looking-glass frame a (or in the standard b) by
screws h, h or by other suitable means. is the spring with which we provide the
stud e, which spring by bearing on the surface of the plate g causes the head of
the stud to be in frictional contact with the slotted plate c. j is the T-shaped
pivot which we form upon the plate g for suspending the glass between its
standards, the said pivot working in an aperture k in a bent plate 1, Figures 6
and 7, secured to the standard 6 (or to the frame a) by screws m, m or other
suitable means, the plate being formed with a slot n to allow of the edgewise
introduction of the neck of the pivot j into the aperture k and its easy removal
therefrom when required.
By this construction it will be obvious that when the looking-glass is swung
upon its pivot j from the vertical position shewn in full lines in Figure 2 to an
inclined position, as indicated by the dot and dash lines, the plate g in swinging
forward will cause the stud e to slide in the slotted plate f which will move on its
pivot d and the friction between the stud and slotted plate will cause the looking-
glass to remain in the position to which it has been adjusted.
If the looking-glass be provided with ordinary means of suspension we construct
the movement in the same way as that hereinbefore described except that, as
shewn in Figures 8 and 9, we form the plate g without the T-shaped pivot, and
the corresponding bent plate shewn in Figures 6 and 7 is of course not required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
a
1. A swing movement for looking glasses and the like having a slotted plate or
link adapted to be pivotally connected to the frame of such looking-glass or the
like or to one of the standards supporting the same and another plate carrying
stud passing through the slot in the said slotted plate, the said stud being pro-
vided with a spring so arranged that it will maintain the head of the said
stud in frictional contact with the slotted plate, substantially as hereinbefore
described.
2. The combination with a swing movement for looking-glasses and the like
having a spring-stud entering a slotted plate in the manner referred to in the

page_text: preceding claiming clause, of means for suspending such looking-glass or the like,
substantially as set forth.
3. The manufacture and use of the improved movements for swing looking-
glasses and the like hereinbefore described and illustrated in the accompanying
drawing.
