Sealed the 22nd September 1866, and dated the 27th March 1866.
PROVISIONAL SPECIFICATION left by the said Salom Henry Salom at
the Office of the Commissioners of Patents, with his Petition, on the
⚫ 27th March 1866.
I, SALOM HENRY SALOM, of Edinburgh, and also of Regent Street, London,
Optician, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE CONSTRUCTION OF GOGGLES TO BE USED FOR THE CURE OF 'STRABISMUS'
OR SQUINT, WHICH SAID IMPROVEMENTS ARE ALSO APPLICABLE TO THE STAGES OF
MICROSCOPES," to be as follows, that is to say :-
My Invention consists in the application of an improved mechanical
arrangement in the construction of goggles or spectacles used for the cure of
strabismus or squint, which said arrangement is also applicable to the con-
struction of the stages of microscopes.
In the application of my Invention to the construction of goggles I fix in

page_text: the
frame of the goggle a plate, preferably of metal, having in it a central
aperture or hole. This plate occupies the position and is similarly fixed and
placed as that of the glass in ordinary spectacles. On its outer surface is
another parallel plate, having also an orifice in its centre, but much smaller
than that in the first-mentioned oue, and attached to it in such a way that it
can be moved in any dirction in a plane parallel to the fixed plate. I effect
this motion by means of a pair of screws placed at right angles to each other,
so that I can vary the position of the aperture of the outer plate. Through
this aperture the rays of light pass to the iris of the eye, and by varying the
position of the aperture right or left, up or down, the iris gradually adapts
itself to a similar position; when the proper position of the aperture is
obtained it may be rigidly fixed if necessary by means of a clamping screw.
In microscopes I apply the same arrangement to the object stages, so that
by means of the motion given to the moveable plate the object under
inspection may be gradually brought under the lens.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Salom Henry Salom in the Great Seal Patent Office on the
27th September 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SALOM
HENRY SALOM, of Edinburgh, and also of Regent Street, London, Optician,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of March, in the year of our
Lord One thousand eight hundred and sixty-six, in the twenty-ninth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Salom Henry Salom, Her special licence that I, the
said Salom Henry Salom, my executors, administrators, and assigns, or
such others as 1, the said Salom Henry Salom, my exécutors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF GOGGLES TO BE
USED FOR THE CURE OF 'STRABISMUS' OR SQUINT, WHICH SAID IMPROVEMENTS ARE
ALSO APPLICABLE TO THE STAGES OF MICROSCOPES," upon the condition (amongst

page_text: thers) that I, the said Salom Henry Salom, my executors or administrators,
y an instrument in writing under my, or their, or one of their hands and
eals, should particularly describe and ascertain the nature of the said Inven-
ion, and in what manner the same was to be performed, and cause the same
o be filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Salom Henry Salom, do hereby
declare the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, that is to say:-
My Invention consists in the application of an improved mechanical
arrangement in the construction of goggles or spectacles used for the cure of
strabismus or squint, which said arrangement is also applicable to the con-
struction of the stages of microscopes.
.In the application of my.
Invention to the construction of goggles I fix in
the eye frame of the goggle a plate, preferably of metal, having in it a central
aperture or hole. This plate occupies the position and is similarly fixed and
placed as that of the glass in ordinary spectacles. On its outer surface is
another parallel plate having also an orifice in its centre, but much smaller'
than that in the first-mentioned one, and attached in such a way that it can
be moved in any direction in a plane parallel to the fixed plate. I effect this
motion by means of a pair of screws placed at right angles to each other, so
that I can vary the position of the aperture of the outer plate. Through this
aperture the rays of light pass to the pupil of the eye, and by varying the
position of the aperture to the right or left, up or down, the eye gradually
adapts itself to a similar position. When the proper position of the aperture
is obtained it may be rigidly fixed if necessary by means of a clamping
screw.
In microscopes 'I apply the same arrangement to the object stages, so that
by means of the motion given to the moveable plate the object under
inspection may be-gradually brought under the lens.
"
In order more clearly to illustrate the foregoing description I have appended
to this Specification the accompanying Drawings, which shew the most con
venient. mode of carrying out my Invention, though I reserve to myself the
right of substituting for any of the parts any other well-known details which
will effect the same movement, or making use of any modifications of the
same, providing the main principles of arrangement and construction are
retained.

page_text: DESCRIPTION OF DRAWINGS.
Figure 1 is a front elevation of my apparatus, being the eye of a pair of
goggles or spectacles, the scale being enlarged to about twice the ordinary
size for the purpose of illustrating more clearly the different parts; Figure 2
is an end view of Figure 1 ; and Figure 3 is a section of the same taken
through the line 1, 2. Similar letters indicate the same or similar parts in
the different Figures.
a is a metal plate which I form of any shape, but preferably round or oval,
and which I place in exactly the same position as the lens of au ordinary pair
of spectacles; in this plate are formed. a series of holes or slots 6, b, b, b, in
which are fixed the small blocks c, c, c, c; these blocks or bearings are formed
each with a shank or neck which passes through the plate a, and is fastened
with a-washer plate and pin d at the back of the plate a, and so that they can
slide easily backwards and forwards in the slots. The plate a has also a
circular and centrical hole e formed in it, shewn in the section (Figure 3);
covering this is the plate or cap f, which is held in its place by the arms or
spindles 9, 9.9.g, which pass through the small blocks or bearings c; on this
.cap or sliding cover are two studs h, h, with the screws i, i; turning in them,
two of the blocks or bearings c, c, being prolonged and tapped with a thread
for the purpose of forming nuts for the screws i, i. This will be more easily
seen on reference to the Figures 2 and 3. The action is as follows: -The
screws i, i, being turned by means of the milled heads k, k, the sliding cover
is brought either to the right or left, up or down, according as the screws are
turned, and the central aperture l in the cover f is moved farther or nearer to
the centre of the aperture or opening in the plate a; thus I am enabled to
cause the rays of light to pass to the iris of the eye in any direction, and by
the continual use of the goggles the eye gradually adapts itself to the desired
position, the action being in the case of strabismus or squint to arrange the
small central hole in the sliding cover, so as to almost coincide with the
direction of the iris of the eye, and gradually as the eyes get accustomed to
the use of the goggle to bring the hole nearer and nearer to the centre until
the right position is attained.
The application of a similar arrangement to the stages of microscopes will
-be perfectly apparent froin this description, so as to bring all parts of the
object under inspection successively under the lens.
Having now described my Invention, and how the same is constructed,
arranged, and applied, I wish it understood that what I claim and desire
secured to me by the before in part recited Letters Patent is, the application

page_text: and use of the mechanical arrangement here-within described in the con-
struction of goggles and spectacles when made use of for the cure of
strabismus or squint, and also when applied to the construction of the stages
of microscropes, substantially as here-within described and set forth and
illustrated in the Drawings accompanying this Specification.
In witness whereof, I, the said Salom Henry Salom, have hereunto set
my hand and seal, this Twenty-fourth day of September, in the year
of our Lord Oue thousand eight hundred and sixty-six.
SALOM HENRY SALOM. (L.S.)
