SAMUEL TWEEDALE 183 Oldham Road Rochdale Cycle Maker JAMES CLEGG
131 Manchester Road Rochdale Cycle Maker do hereby declare the nature of this
invention to be as follows:-
-
Our invention relates to the fork-crown or junction of the two fork sides used in
carrying wheels in cycles or other vehicles. The improvement consists in the
manner of formation. It is made in two halves stamped or moulded to the required
shape. One half has two holes punched or made in it where it is essential for the
fork sides to pass into the crown and also one hole where the steering column is
required to come through. The other half has one hole only made in it where the
steering column is required to pass through. These two halves when fitted in their
required places and brazed or fastened in any other suitable manner, form one
hollow fork-crown.

On the drawing appended hereunto
Fig. 1 shows a view of the upper half of the improved crown as seen from
below;
Fig. 2 a side view on the left half and a longitudinal section on the right half
of the figure;
Fig. 3 a top view of the lower half of the crown.
The improved crown is made in two halves a and beach stamped, pressed or
moulded so as to form a trough or open box of a similar shape as shewn on the
drawings. The upper half a has one hole a¹ in the centre for the steering columu c
or equivalent part on which the fork is to be mounted to pass through, and is made
with enlarged ends of the internal shape required to fit to the fork sides d. The lower
half b has three holes punched into it, one 6' in the centre where the steering column
or its equivalent passes through, and one hole 6 at each end for the fork sides to
pass into it. These two halves a and b are fitted together at their edges and brazed

In some cases holes for the fork sides to pass through may be punched into
both halves.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
