do,
I, PHILIPPE AMÉDÉE DEVY, of 10, Old Jewry Chambers, Old Jewry; do
hereby declare the nature of the Invention for "IMPROVEMENTS IN THE FRAMES
OF SWING LOOKING GLASSES " to be as follows:---
This Invention consists of means of constructing frames of swing looking
glasses with a view to employ two looking glasses at one time, in order that
the back of the head may be reflected by the upper glass into the lower glass,
and in such manner that the person using the glasses may see the face as well
as the back of the head in the lower-of the two glasses.
For this purpose the lower of the two glasses is supported in a frame so, as
to be caused to assume any desired inclination, in like manner to ordinary swing.
looking glasses. The upper glass, it is preferred, should be mounted on 'a
sliding part of the frame, and to move on an axis, so as to bring the upper..

page_text: glass to a position behind the bead of the person looking into the other or
lower glass; and this is most conveniently done by mounting the upper glass
on a lever, carried by a sliding bar or rod held in an inclined position, and by
means of a cord and guide pulleys to move the upper glass to an inclined
position by the act of sliding out the inclined bar or rod; but the cord!
and pulleys may be dispensed with, and the lever retained in position by a
.catch.
