PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Inspecting the Throat,
Eyes, or other Organs, and for similar purposes.
I, CHARLES SALOMON NEWMAN, of 13, Pembridge Crescent, in the County of
London, Gentleman, do hereby declare the nature of my said invention to be as
follows:-
This invention relates to improved means or apparatus for inspecting the throat,
eyes, or other organs or cavities of the body and for similar purposes.
It has for its object to provide means whereby a strong and concentrated light
is, or may be thrown upon the part, organ or object to be inspected whilst protecting
the eye of the observer from the glare of such light and my improved apparatus
will be less cumbersome and more convenient in use than those heretofore used for
similar purposes.
According to this invention I provide a baseplate suitably padded at the back
and provided with means for holding it in front of the eye, for instance a band may
be provided which passes round the operator's head....
The base plate has a perforation at its centre and either itself forms a diaphragm
to protect the operators eye or is fitted with a suitable diaphragm for this purpose.
A tube may project from the diaphragm for further protection.
Round the central aperture or tube is placed an annular incandescent electric
lamp supplied with current by any suitable means.
Now when the apparatus is placed in front of the operators eye, and current
passes through the filament of the lamp, the light is thrown directly upon the
object in front of the eye whilst the eye itself is entirely protected against the
glare the view of the object being at the same time entirely unobstructed.
At the back of the lamp a suitable reflecting surface may be provided to improve
the effect. In some cases the apparatus is doubled so that both eyes may be used
simultaneously.
I may also provide a lens or lenses, either in front of the light or behind the
diaphragm; for the purpose of aiding in the operators work and I may combine my
invention with mirrors and other subsidiary devices.
It will be evident that my invention may be used instead of an eye mirror, for
laryngoscopic, ophthalmic, and various other surgical examinations and operations.
It may also be used in engraving gems, or examining the same, and in fact
wherever a strong light is to be concentrated upon a comparatively small surface
for the purpose of minute examination or for carrying out delicate operations.

Eyes, or other Organs, and for similar purposes.
I, CHARLES SALOMON NEWMAN of 13 Pembridge Crescent in the County of
London Gentleman, 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 improved means or apparatus for inspecting the throat
eyes, or other organs and for similar purposes.
It has for its object to provide means whereby a strong and concentrated light
may be thrown upon the part, organ, or object to be inspected whilst protecting
the eye of the observer from the glare of such light, and my improved apparatus
will be less cumbersome and more convenient in use than those heretofore used for
similar purposes.
According to this invention provide a base plate suitably padded at the back
and provided with means for holding it in front of the eye, for instance a band may
be provided which passes round the operators head.
The base plate has a perforation at the centre and either itself forms a diaphragm
to protect the operators eye or is fitted with a suitable diaphragm for this purpose.
A tube may project from the plate or diaphragm for further protection.
Round the central aperture or tube is placed an annular incandescent electric
lamp supplied with current by any suitable means.
Now when the apparatus is placed in front of the operator's eye and the current
passes through the filament of the lamp, the light is thrown directly upon the object
in front of the eye whilst the eye itself is entirely protected against the glare aud
the view of the object is unobstructed.
At the back of the lamp a suitable reflecting surface may be provided to improve
the effect.
I may also provide a lens or lenses either in front of the eye or behind the
diaphragm for the operators work.

It will be evident that my invention may be used instead of an eye mirror; for
laryngoscopic, opthalmic and various other surgical examinations and operations,
it may also be used in engraving gems and examining the same, and in fact
wherever a strong light is to be concentrated upon a comparatively speaking small
surface for the purpose of minute examination or for carrying out delicate
operations.
My invention is illustrated in the accompanying drawings in which
Fig. 1 is a front view of, the apparatus.
Fig. 2 a rear view thereof.
Fig. 3 a side elevation.
Fig. 4 a section through the centre.
Fig. 5 shows a handle for use in connection with the same.
Figs. 6 & 7 are front view and side view of a frame for the apparatus; somewhat
similar to a spectacle frame.
Fig. 8 shows a. stand that may be conveniently used in connection with this
invention.
Fig. 9 a modification of part of the stand.
Like letters indicate like parts in all the figures.
A is the base plate upon which the parts are mounted.
B is a tube rising therefrom to prevent access of lateral rays to the eye, C C is
an incandesent lamp surrounding the tube B and c c are the terminals of the same.

page_text: heat I prefer to line the base plate and other parts surrounding the lamp with a
layer of asbestos cardboard marked 6 in the drawings and to fill the interstices 61
with asbestos wool. Though I prefer this manner of preventing access of heat to
the eye I may nevertheless use other means if preferred.
D is the rim of the base plate raised to surround the lamp and protect it but it
may be made separate and conveniently attached thereto.
At the rear of the base plate a padded cushion may be placed as herein above
referred to but I find it more convenient to provide an eye-piece E of known shape,
this eye piece is made in two pieces united by a bayonet joint e so as to allow ready
access to the lens F for the purposes herein above explained.
Gis a suitable knob serving to attach the apparatus to a handle, frame or
stand.
A convenient form of handle is shown in Fig. 5, this has a screwheaded end g¹
which allows it to be inserted in the threaded hole g in the stem of the knob G.
H, Figs. 6 & 7 shows a kind of spectacle frame to receive the apparatus and this
frame H has a socket in which the knob G is fixed so as to bring the eye-piece
into convenient position for either eye, h¹¹ are bands or ribbons for attaching
the whole to the operators head.
Fig. 8 is a stand of a construction substantially similar to that of an ordinary
stand, but fitted with a socket h similar to that shown in Fig. 6 and provided with
a joint that permits the apparatus to be lowered below the level of the table, say,
on which the stand J is placed.
Fig. 9 is a clamp that may form the base of the stand J in order to permit the
same to be firmly fixed in place on a table or the like.
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.) An apparatus for use in endoscopic or other surgical operations, in engraving
and other cases where a concentrated light is to be cast on a small surface, con-
sisting of a base-plate A carrying a circular or approximately circular incandesent
electric. lamp and having a perforation concentric with the lamp, the whole
arranged substantially as and for the purposes set forth.
(2.) An apparatus for inspecting small surfaces consisting of a base plate A, the
protecting tube B, the lamp C, (protected as described) and an eye-piece E, with
or without a lens F substantially as shown in the drawings.
(3.) In an apparatus for inspecting small surfaces, the means for preventing
access of heat to the eyes as set forth and illustrated in the drawings.
Dated this 10th day of March 1896.
