PROVISIONAL SPECH
An Improved Movement for Adjusting the Position of Swing
Looking Glasses, Sashes, Ventilators, Reading Desks, and the
like.
I, JAMES PERCY ERNEST PROUD, of Fortal, Killiney, in the County of Dublin,
Ireland, Student, Engineering School, Trinity College, Dublin, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the construction of a novel and simple movement for
adjusting swing looking glasses, sashes, ventilators, reading desks, and the like at any
desired angle or position.
The improved movement suitable for a looking glass is constructed of a worm or
screw mounted in bearings fixed to one of the side standards of the looking glass, and
adapted to work in a toothed segment fixed to the side of the looking glass concen-
trically with the pin on which the glass pivots.
By this arrangement if the worm or screw be turned by means of a milled head or
knob with which it is provided the rotation of the screw will cause the toothed segment
to turn thereby moving the looking glass on its pivots and allow of the glass to be
adjusted to any desired angle, and the glass will be held in this position until the
screw-be again turned.
The construction of the movement for adjusting swing-sashes, ventilators, reading
desks and the like will be substantially the same as that hereinbefore described.

An Improved Movement for Adjusting the Position of Swing
Looking Glasses, Sashes, Ventilators, Reading Desks, and the
like.
I, JAMES PERCY ERNEST PROUD, of Fortal, Killiney, in the County of Dublin,
Ireland, Student Engineering School Trinity College, Dublin, 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 the construction of a novel and simple movement for
adjusting swing looking glasses, sashes, ventilators, reading desks, and the like at any
desired angle or position.
The improved movement suitable for a looking glass is constructed of a worm or
screw mounted in a bearing or bearings fixed to one of the side standards of the.
looking glass, and adapted to work in a toothed segment fixed to the side of the
looking glass concentrically with the pin on which the glass pivots.

page_text: To enable my invention to be fully understood I will describe the same by reference
to the accompanying drawing, in which :-
Figure 1 is a sectional elevation of so much of a looking glass frame as is necessary
to illustrate the application of my invention thereto; and,
Figure 2 is a side elevation:
Figures 3, 4 and 5 are a face view, an edge view and a plan of one part of my
improved movement; and,
Figures 6, 7 and 8 are similar views of the other part of the movement.
a, b are two metal plates, one of which is provided with a pin or pivot c designed to
enter a hole d in the other. e is a toothed segment which, by preference, is cast in
one piece with the plate a, and is a worm carried in a bearing or bracket g on the
plate and designed to engage with the teeth of the segment e and to be rotated by
means of a milled head h fixed to the shank of the said arm.
In order that the worm shall not be unnecessarily small or the width of the
segment e unnecessarily great, the plates a and b are recessed on those parts adjacent
to the worm as at i, i, as clearly shewn in the drawing.
In fixing my improved adjuster the part a is fixed to the swinging frame j and the
part 6 to the support or standard k.
By this arrangement if the worm or screw be rotated by means of the milled head.
the consequent rotation of the worm will cause the toothed segment e to turn,
thereby moving the looking glass on its pivots so that it can be adjusted to any
desired angle, the glass being held in this position until the screw be again turned.
The construction of the movement for adjusting swing-sashes, ventilators, reading
desks and the like will be substantially the same as that hereinbefore described.
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 :-
1. A movement for adjusting swing looking glasses, swinging sashes, ventilators,
reading desks and the like, baving two plates pivoted together, one of which plates is
provided with a segmental rack whilst the other is formed with a bearing or bracket
carrying a worm which engages with the said rack, substantially as described.
2. The improved adjusting device for swing looking glasses and the like, consisting
of the parts constructed and combined substantially in the manner hereinbefore
described and illustrated in the accompanying drawing and operating as, and for the
purposes, set forth.
