PROVISIONAL SPECIFICATION.
An Improved Watch for Indicating Speed of Bicycles.
I ARTHUR ANDERSON WATKINS of Bala Lodge Vanbrugh Park Blackheath
in the County of Kent Engineer, do hereby declare the nature of this invention.
to be as follows:-
My invention rélates to watches used by bicyclists and is such that they may be
made to indicate the speed of travelling.
Through the face of the watch I cut a sector, and under this face I have a hand
revolving (from the centre of the watch preferably) which hand is only visible as
it passes beneath the open sector in the face.
This hand is made to travel at such a pace, and the opening is made of such a
size that the hand is visible for a certain number of seconds only every minute or
part of a minute. This number of seconds is ascertained by calculation and will
depend upon the size of the wheel or the gearing of the bicycle and is such that
if the strokes of the pedal are counted while the hand is visible the number counted
will indicate the miles per hour the bicycle is travelling.
Such a watch can be similarly arranged for other measurements of distance such
as kilometers, leagues, or versts per hour. The manner of indicating can also be
otherwise arranged. The hand for instance could revolve on the surface of the
dial and the strokes counted while it passes between marks on the face of the
watch, or over a coloured segment; or a revolving dial could take the place of
the hand and in the same manner indicate regular intervals of time such as would
record speed by the counting of revolutions of the pedal.
Dated this 30th day of November 1892.

COMPLETE SPECIFICATION.
An Improved Watch for Indicating Speed of Bicycles.
I ARTHUR ANDERSON WATKINS of Bala Lodge Vanbrugh Park Blackheath
in the County of Kent 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 :-
My invention relates to watches used by bicyclists & other velocipedists and is
such that they may be made to indicate the speed of travelling. Through the face
of the watch I cut an open sector and under the face I have a hand revolving
in such a manner that it is only visible as it passes beneath the open sector in the
face. This hand is made to travel at such a pace & the opening is made of such a
size that the hand is visible for a certain number of seconds only during every
revolution; and the time it is visible is such that if the bicyclist counts the strokes
of the pedal while the hand is visible that number counted will indicate the number
of miles per hour he is travelling.
The manner of indicating can also be otherwise arranged. The hand for instance
could revolve on the surface of the dial instead of underneath it, and the strokes
of the pedal counted while it passed between the marks on the face of the watch,
or while it passed over a coloured segment, or a revolving dial could take the place
of the hand, or instead of a visible hand, mechanism in the watch might strike a
bell or gong at regular intervals to answer the same purpose. The other parts of
the watch not here described are the same as in an ordinary watch.

page_text: I will now describe my invention more fully by reference to the drawing..
B. B. is the dial or face, the centre part of which is figured and has hands as an
ordinary watch. Cut in the face or dial B. B. is an open sector A. A. and under
the face or dial travels the hand C which is only visible as it passes the
opening A. A.
The length of the opening and the pace the hand C travels are so arranged as
to answer the purpose herein described.
Having now fully described my invention I claim :—
: The combination of revolving hand C in connection with sector A. A. on
dial B. B. or other like attachments in connection with an ordinary watch
substantially as herein described, and actuated as described, and for the purpose
named.
