I, FREDERICK JAMES BIGGS Merchant, of Leadenhall Buildings Gracechurch Street
in the City of London, do hereby declare the nature of this invention to be as
follows:-
The fitting up or combination of racing or field glasses with a stop watch in such a
way that the indicating hand of the stop watch may be set going or stopped by the
pressure or movement of the viewer's finger while the said glasses are being held at
the viewer's eyes.
In order to carry out this my invention I make a suitable chamber on the outside
of the Racing or Field Glasses on which the stop watch is mounted or in which it
will lie singly imbedded and in such a way that the watch may be removed from, or
made fast to, the said Glasses, and so that the face of the watch can be seen through
the outer or separate case in which the said Glasses are carried.

page_text: 1, FREDERICK JAMES BIGGS, Merchant, of Leadenhall Buildings, Gracechurch
Street, in the City of London 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 :-
Field, Racing, or other Binocular Glasses as hitherto made, have not been fitted or
provided with time indicators for registering the records of times consumed in
connexion with racing, general sports, naval, military, and scientific observations,
such records having always hitherto been taken by means of a distinct and separate
apparatus, necessitating additional assistance, or an interference with the continuous
visual observation of the object under consideration.
In order to enable one person to make telescopic observations, and simultaneously
to obtain with facility, a true record of the progress of time in conjunction with rates
of speed, distances traversed, or any data derivable from chronographic, registration,
I construct a combined apparatus, as follows:-
I attach to Binocular Glasses of any construction, the fittings requisite to hold a
stop-watch or chronograph in the position most convenient for starting or stopping
the indicator by a slight movement of the observer's finger without necessitating any
removal of the glass from the eyes.
This may be achieved in a variety of ways, but the means which I adopt, by
preference, is to affix to the back of the stop-watch or chronograph A a hollow loop or
catch of metal B to loop, clip, or take onto a corresponding piece, spring, or projection C
mounted centrally upon the Binocular Glasses, at any required angle.
In order to make the angle of elevation adjustable, I construct the spring, or
projecting piece C upon which the recording instrument engages, with a small hinge-
joint and set-screw C³. The combined apparatus is instantly detachable, if it be
desired to use either apparatus separately.
By another method, I make an extra case or chamber to hold the stop-watch or
chronograph, affixing to the back of the said case or chamber, a loop or other suitable
fastening, as herein before described.
I fit the outer or separate case in which my combined apparatus is carried, with a
glass panel, or other transparent centre-piece, so that the face of the stop-watch or
chronograph may be seen, without withdrawing the Instrument.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is
First. The combined arrangement of a chronograph or stop-watch mounted upon a
Binocular or other Field Glass, substantially as hereinbefore described.

page_text: Second. The construction and arrangement of parts for the attachment and
removal of the same, substantially as, and for the purpose hereinbefore described.
Third. The construction of the outer case, with a glass or other transparent panel,
substantially as herein before described.
In witness whereof, I the said Frederick James Biggs have hereunto set my
hand and seal, this Seventeenth day of November, One thousand eight hundred
and eighty seven.
