Improvements in or connected with the Chain Wheel Adjustment
of Cycles.
We, EDWARD WILSON, Managing Director, and HARRY HERBERT MOORE, Draughts-
man, both of The New Hudson Cycle Company Limited, of Summerhill Street,
in the City of Birmingham, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in or connected with the chain wheel
adjustment of cycles and consists as follows:-
The slot in the back fork end (on each side) is made somewhat wider than usual,
and further is made with one or more recesses or gaps in its sides. In this slot
is now fitted a removable piece, so that when placed therein no andwise move-
ment is permitted. In this piece is also an open ended slot whose two sides are
screwthreaded for some distance to receive a screw adjustment pin which is capable
of a
move-
rotating movement but is prevented from longitudinal
ment. A sliding plate is now provided which lies beside the said
piece, having in it a hole through which passes the end of the hub spindle
the nut of which lies against the outside of such plate. The hub spindle is pre-
vented from rotation by means of its having one or more flats (generally two)
formed upon it, where it passes through the removable piece in the fork ends.
The plate is further connected to the screw adjustment pin by having a portion
of its one end turned up at right angles and so shaped as to fit into a groove
turned in the pin near the head, and thus to form a bearing for the pin, and
further having a slitted portion also turned up and formed in a similar manner
to form a bearing for the end of said pin, which latter is again turned down
similarly for such purpose.
Hence the said plate covers and protects the adjustment pin and conceals the
fork end, while it may be readily moved in or out by the screw, carrying with it
of course the hub spindle to the required adjustment.
Dated this 24th day of December 1897.

page_text: the City of Birmingham, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to improvements in or connected with the chain wheel
adjustment of cycles' and consists as follows:--
In order to more clearly explain this our invention, we have appended here-
unto an illustrative drawing upon which are figures and numbers of reference,
similar numbers referring throughout the several views to the same thing or part.
Fig. 1, is a side view of a cycle back fork fitted with this our invention.
Fig. 2, is a plan view of the invention on line A-B Fig. 1.
Fig. 3, is an end view of the same.
Fig. 4, is a detailed view of the fork end.
Fig. 5, is a detailed view of the " removable piece" hereinafter referred to.
Figs. 6 and 7, are side and end views of the adjustment plate.
Fig. 8, is a detailed view of the adjustment pin.
11, is the back fork end of a cycle in which is made the slot 12, having the
gaps 13, 13. This slot 12, is made somewhat wider than usual, so that the remov-
able piece 14, may be fitted therein, with the projections 15, 15, taking into the
recesses 13, 13, so that when placed therein no endwise movement is permitted.
In this piece is also an open ended slot 16, whose two sides are screw-threaded for
some distance to receive a screw adjustment pin 17, which is capable of a rotating
movement. A sliding plate 18, is now provided which lies beside the said plate 14,
having in it a hole 19, through which passes the end 20, of the hub spindle
the nut 21, of which lies against the outside of such plate, see Figs. 1 and 2.
The hub spindle is prevented from rotation by means of its having one or more
flats 22 (generally two) formed upon it, where it passes through the removable
piece 14, in the fork ends. The plate 18, is further connected to the screw adjust-
ment pin 17, by having a portion 23, of its one end turned up at right angles
and so shaped as to fit into a groove 24 turned in the pin near the head, and
thus to form a bearing for the pin, and further having a slitted portion 25, also
turned up and formed in a similar manner to form a bearing for the end 26, of
said pin, which latter is again turned down similarly for such purpose.
Hence the said plate 18, protects the adjustment pin and conceals very much
of the forked end, whilst it may be readily moved in or out by the screw pin 17,
carrying with it of course the hub spindle to the required adjustment.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In cycle fork adjustments the combination with the fork end having the
slot 12, with gaps 13, 13, of the removable piece 14, fitting therein, and plate 18,
adjusted by pin 17, carried in piece 14, 'the hub spindle being carried in such
plate 18, all substantially as described and for the purposes specified.
