PROVISIONAL SPECIFICATION.
Improvements in Speculums for Medical and Surgical Purposes.
I, JAMES ARNOLD, of the firm of Arnold and Sons, of West Smithfield in
the City of London Surgical Instrument Makers do hereby declare the nature of
this invention to be as follows :-
Hitherto these instruments have been generally made cylindrical or tapering
throughout. their length, and when so made they are liable to get out of position
while in use or do not remain in situ unless held there by the hand of the operator.
Now the object of my invention is to remedy this defect, while at the same time
both hands of the operator are at liberty.
According to my invention I adapt or apply at or near to the base of the
instrument an enlargement which may be of globular or other equivalent form, and
this is protected by the usual flanged reflecting end, between which and the base
of the tubular portion of the instrument, the said enlargement is placed. By this
means when the instrument is in situ, the enlargement makes it self retaining.
The entrance end of speculums hitherto, when covered with elastic gum,
vulcanite, or other material, the covering has extended to and over the end, and
this end becomes roughened and broken away, which is not only unpleasant to the
patient, but is dangerous, as it is next to impossible to cleanse the roughened end
and render the instrument "aseptic;" to prevent this, the covering does not,
according to this part of my invention, extend to the extreme end, but the end
proper slightly projects beyond the said covering.
Speculums constructed according to my invention may be made of glass covered
with gum, vulcanite, or other material, or of metal, celluloid, or other substance
or combination.

COMPLETE SPECIFICATION.
Improvements in Speculums for Medical and Surgical Purposes.
I, JAMES ARNOLD, of the firm of Arnold and Sons, of West Smithfield, in the
City of London, Surgical Instrument Makers, 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 :-
Hitherto these instruments have been generally made cylindrical or tapering
throughout their length, and when so made they are liable to get out of position.
while in use, or do not remain in situ unless held there by the hand of the operator.
Now the object of my invention is to remedy this defect, while at the same time
both hands of the operator are at liberty.
According to my invention I adapt or apply at or near to the base of the
instrument an enlargement which may be of globular or other equivalent form,
and this is protected by the usual flanged reflecting end, between which and
the base of the tubular portion of the instrument the said enlargement is preferably
placed.
My invention will be readily understood by reference to the accompanying
drawing, on which is shewn a speculum constructed according to my invention,
Fig. 1 being a perspective side view of same, Fig. 2 a perspective end view, and
Fig. 3 a vertical section of same.
A is the enlargement of globular or other equivalent form, B is the flanged

page_text: reflecting end and C is the tubular portion of the instrument. By constructing the
instrument with the part A as set forth, when the same is in situ, the enlargement
makes it self-retaining.
The entrance end D of speculums hitherto, when covered with elastic gum,
vulcanite, or other material; the covering has extended to and over the end, and
this end becomes roughened and broken away, which is not only unpleasant to the
patient, but is dangerous, as it is next to impossible to cleanse the roughened end
and render the instrument "aseptic: t prevent this, the covering does not,.
according to this part of my invention, extend to the extreme end D, but the end
proper slightly projects beyond the said covering.
Speculums constructed according to my invention may be made of glass covered
with gum, vulcanite, or other material, or of metal, celluloid, or other substance or
combination.
Having now particularly described and ascertained the nature
said inven-
of my
tion, and in what manner the same is to be performed, I declare that what
claim is :
1. In speculums for medical and surgical purposes, the enlargement of globular
or other equivalent form situated at or near the base of the instrument, being
adjacent to and protected by the usual flanged reflecting end, substantially as and
for the purposes herein set forth.
2. In speculums for medical and surgical purposes having an enlargement of
globular or other equivalent form A, at or near the base of the instrument, causing
the end D of the cylindrical portion thereof to project beyond the usual outer
covering of elastic gum, vulcanite, or other material, substantially as and for the
purposes herein described with reference to the accompanying drawings.
Dated this 25th day of November 1892.
