Improvements in Artificial Eyes.
I LESLIE JEYES of 46 Orbel Street Battersea, in the County of London Civil
Engineer do hereby declare the nature of this invention to be as follows:
The object of this invention is to give to artificial eyes worn by patients the
same movements as those appertaining to natural ones. These movements are
attained by a combination joint piece or a joint piece of such shapes or designs as
will serve the required purpose.
The combination joint piece or joint piece, which are made of non oxydising
metal, are fused or cemented on at a high or low temperature or fixed or fastened
in any other suitable manner to the inner side of the artificial eye behind the iris or
to the inner walling of the outer cup of the eye, which outer cup represents the
convex surface of the eye-ball.
The artificial eye is made to set or fit correctly by the adjustment of the joints,
After the extraction of a natural eye there is always a stump left behind in the
cavity of the same together with the movement muscles which are connected with
the corresponding ones of the natural eye.
On this stump is set the artificial eye and by the close and exact fitting of the
joint or joints which may be represented either by a hollow or solid body and may
be shaped according to the directions of the oculist, the movement-muscles left in
the stump transmit or impart movement or motion to the artificial eye and it. will
move in the same direction as the natural one. By these means the fixed.gaze at
present attached to artificial eyes is done away with.

COMPLETE SPECIFICATION.
Improvements in Artificial Eyes.
I LESLIE JEYES of 46 Orbel Street Battersea in the County of London, Civil
Engineer, 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 :-
The object of this invention is to give to artificial eyes worn by patients the
same movements as those appertaining to natural ones. These movements are
attained by a combination joint piece or a joint piece, of such shapes or designs as
will serve the required purpose.
The combination joint piece or joint piece which are made of a non-oxydising
metal are fused or cemented on at a high or low temperature or fixed or fastened
in any other suitable manner to the inner side of the artificial eye behind the iris or
to the inner walling of the outer cup of the eye, which outer cup represents the
convex surface of the eyeball.
The artificial eye is made to set or fit correctly by the adjustment of the joints.
After the extraction of a natural eye there is always a stump left behind in
the cavity of the same, together with the movement muscles which are connected
with the corresponding ones of the natural eye.

be shaped according to the directions of the oculist, the movement muscles left in
the stump transmit or impart movement or motion to the artificial eye and it will
move in the same direction as the natural one. By these means the fixed gaze at
present attached to artificial eyes is done away with.
The accompanying drawings will more fully demonstrate and explain the improve-
ments in artificial
eyes.
Like letters represent like parts in the drawings which are drawn about twice
their natural size.
Fig. 1, represents a section of the artificial eye, when the joint piece A is in one
piece and fixed to the back of it.
Fig. 2, represents a plan of the same shewing the base B of the joint piece A
which bears upon or connects with the stump left behind in the cavity after the
extraction of the natural eye.
Fig. 3, represents a section of the artificial eye when the joint-piece C is formed
of two separate pieces or parts.
Fig. 4, represents a plan of the same shewing the base D of the joint piece C.
The joint piece A is made of glass or other suitable non-oxydising material and
is attached to the back of the artificial eye in such a position and of such a
depth that the base B may bear upon or be in connection with the stump left in the
cavity after the extraction of the natural eye.
The combination joint piece C consists of two parts E being a spiral of non
oxydising metal covered with a sheath F constructed of glass or other suitable
material. The spiral E is fixed at one end to the back of the artificial eye in a
position and of such a depth so that the base D of the sheath F covering the
spiral E may bear upon or be in connection with the stump left in the cavity after
the extraction of the natural eye. The shape and contour of the bases B or Dare
determined according to the requirements and directions of the oculist and the same
inay be said of the required positions and depths of the respective joint pieces A
and C. The fact of either of the bases B or D resting upon or coming in contact
with the stump which retains the power of movement as the muscles connected
therewith are still unimpaired the artificial eye receives a motion similar to the
natural eye.
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:
An artificial eye constructed with a joint piece A or with a combination joint
piece C as set forth and described and for the purposes specified.
