PROVISIONAL SPECIFICATION.
Improvements in and relating to the Steering Fork Crowns of
Velocipedes.
I, HARRY PARSONS, of Ferndale, Wren Street, Coventry, in the County of
Warwick, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improvement in the steering fork crowns of veloci-
pedes whereby a convenient and easy means of attaching the usual brake tube guide
and tail piece for attachment of the mudguard is provided and the velocipede is
finished in a detail part which up to the present has been most difficult and expen-
sive to finish properly.
According to the present invention, four blocks of hard wood or other suitable
material are so shaped as to enable them to fit in and fill up the spaces formed
between the fork stem, the fork blades and the crown plates. These blocks are
preferably held in position by means of transverse bolts or screwed studs which
also pass through a plate abutting on the front faces of the two front blocks which
carry the brake tube guide and through a similar plate abutting on the faces of the
two rear blocks carrying the tail piece or lug for attachment of the mudguard.
It will be understood that the primary object of this invention is to conceal or
hide a detail of construction which is necessarily extremely difficult to properly
finish. It will therefore be apparent that the visible faces of the blocks may
be finished in any desired manner and the two plates carrying the brake tube
guide piece and mudguard attachment piece may be dispensed with.

Improvements in and relating to the Steering Fork Crowns of
Velocipedes.
I, HARRY PARSONS, of Ferndale, Wren Street, Coventry, in the County of
Warwick, 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;
-

page_text: of velocipedes whereby a convenient and easy means of attaching the usual brake
rod guide and the tail piece for carrying the mudguard is provided, the crowns
rendered solid and greatly. strengthened and a finish is given to them.
In the accompanying drawing which illustrates this invention
Figure 1 is a broken view in side elevation.
Figure 2 is a similar view in front elevation.
Figure 3 is a view in sectional plan on line xx Figure 1.
Figure 4 is a view in plan showing a modification.
Throughout the views similar parts are marked with like letters of reference.
According to this invention, the space between the crown plates Z, Z, and between
the stem X of the fork and the members Y, Y, of the fork, is filled up with
blocks A, A, of hard wood or other suitable material. Usually four blocks are em-
ployed which are suitably shaped to fit in pairs on each side of the stem X of the
fork each pair being held in position by means of a transverse bolt B. Suitable
plates C and D are interposed between blocks A, A, etc. and the heads b and nuts b
respectively of the bolts B, B. These plates C and D carry the brake rod guide E
and the tail piece F for supporting the mudguard respectively as shown in Figures 1,
2 and 3.
When machines are not fitted with brakes and, or, mudguards, the plates C
and D may either be entirely dispensed with or may simply form washer plates.
When the plates are dispensed with two blocks only may be employed as shown
in Figure 4 the exterior parts of the said blocks conforming or approximately
conforming to the shape of the crown plates Z, Z, as shown in which case the two
blocks may be conveniently drawn together and held in place by a pair of wood
screws 22 as shown.
It will be understood that by this invention the crowns of forks are materially
strengthened and that a part which is extremely difficult and expensive to finish
properly is concealed and effectively finished off.

Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is;
(1) The improved method of strengthening and adding finish to the crowns of
the steering forks of velocipedes by filling the spaces in. the said crowns with blocks
of wood or other suitable material, as set forth.
(2) In a velocipede the combination with the steering fork, of blocks such as
A, A, etc., adapted to fill up the spaces in the said crown and to be fixed together
by transverse screws or bolts, as set forth.
(3) In a velocipede the combination with the steering fork, of blocks such as
A, A, etc., of plates such as C and D and of screw bolts such as B, as and for the
purpose set forth.
(4) In a velocipede the combination with the steering fork, of blocks such as
A, A, etc., of a plate such as C carrying a guide such as E for the brake rod, of a
plate such as D carrying a tail piece such as F for supporting a mudguard, and of
bolts such as B for holding the parts together, as set. forth.
Dated this 16th day of February, 1895.
