An Improved Appliance for Adjusting Mirrors.
I, ELLIS CAMPBELL DRYDEN, of 15, Montpelier, Edinburgh, Draughtsman, da
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved appliance for adjusting mirrors.
It consists in fixing to the back of the mirror frame, a metal plate which has
a semicircular piece projecting therefrom, that is to say, which projects out from
the back of the mirror frame. Upon the back of the pillar or
standard which supports the axle or pivot of the mirror is a pivoted
lever, one arm of which engages with notches which are formed in the
semicircular metal plate or piece at the back of the mirror frame, the arrangement
being such that the mirror can be set and locked at any desired angle. The
lever arm may be kept within the notches by means of a spring, the other arm of the
lever being provided with a finger piece, the arrangement being such that by
pressing this end of the lever against the power of the spring, the other end of
the lever is disengaged from the teeth of the semicircular piece.
As a modification, the notched semicircular piece may be fixed at the side of the
mirror frame.
The notches in the semicircular piece may be rectangular or they may be curved.
under which latter arrangement, the semicircular piece. would disengage itself
from the lever, or adjust its position, upon moving the angle of the mirror and
without the necessity of actuating the lever. Similar modifications may be given
effect to in the carrying out of the principle of my invention.
An improved Appliance for Adjusting mirrors.
I, ELLIS CAMPBELL DRYDEN, of 15, Montpelier, Edinburgh, Draughtsman, 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 an improved appliance for adjusting mirrors and has
for its object to enable the angle at which the mirror is used to he regulated
and held in the desired position by easily actuated and reliable means; the applianee

page_text: being such that it is not conspicuously to view and does not become ineffective
through ordinary use.
The accompanying drawings illustrate the method of carrying out my invention,
Fig. 1 being a rear elevation and
Fig. 2 a sectional plan of a portion of a mirror and its supporting pillar or
standard, fitted with my improved appliance.
Fig. 3 is a side view of the portion of the mirror showing the notched regulating
segment or plate.

Fig. 4 is a view similar to Fig. 2, of a modification.
Referring to Figs. 1 and 3 of the said drawings, I fix to the side of the mirror
frame A a semicircular plate or piece B, the periphery of which is formed with
notches b.
Upon the back of the pillar or standard C which supports the pivot c of the
mirror is a lever D pivoted at d, the one arm of which engages with the notches b.
in the plate B. the arrangement being such that the mirror can be set and locked
at any desired angle. The lever arm may be kept within the notches by means
of a spring E. the other end of the lever being provided with a finger piece e so
that by pressing this end of the lever against the power of the spring, the other
end of the lever is disengaged from the notches of the semicircular piece.
To ensure the notched plate being fixed concentrically with the pivote it may
he marked with 3 arrows. Fig. 3, all of which point towards the centre with which
the circle of the plate B is described. The attachment is thereby facilitated.
Figs. 1 and 2 show the lever secured behind a circular pillar, the lever arm
being straight; as, however, the supporting pillars vary in design, the arm of the
lever may require to be curved, as shewn in Fig. 4, where the supporting pillar
is shown of a rectangular shape in cross section.
As a modification the notched regulator may be carried by a plate secured to
the back of the mirror frame in place of at the side, if found convenient.
The teeth in the semicircular piece may be rectangular as shewn, or they may
be rounded, under which latter arrangement, the semicircular piece would dis-
engage itself from the lever or adjust its position, upon altering the angle of the
mirror, without the necessity of actuating the lever. Similar modification may
he given effect to in the carrying out of the principle of my invention.
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
I claim is:-
The improved appliance for adjusting mirrors, whereby the mirror can be set
and locked at any desired angle; constructed, arranged and actuating, substan-
iially in the manner as hereinbefore described and shewn in the accompanying
drawings.
