PROVISIONAL SPECIFICATION.
Certain Improvements in Safety Bicycles and other Velocipedes.
I, ROBERT WALKER SMITH, of The Eadie Manufacturing Company, Limited,
of Hunt End, Redditch, in the County of Worcester, Cycle Manufacturers'
Manager, do hereby declare the nature of this invention to be as follows:-
This invention has reference to safety bicycles tandem bicycles and other
velocipedes and this invention consists of the hereindescribed improved construction
of the front fork and steering head so as to strengthen the same and effectually
prevent their breaking through the vibration and strains to which these parts are
subjected when the machine is being ridden..
In carrying out my invention I strengthen the said front fork by fixing thereto
two side tubes which extend from the wheel axle to the top of the steering head.
Thus each arm of the fork is strengthened by being made of two tubes side by
side preferably of corresponding shape. The said outer strengthening tubes are at
their lower ends fixed to the fork where the axle passes through, and the said outer
tubes pass through holes in and are connected to the cross bar at the top of the
fork and the upper ends of the said outer tubes are connected to a cross head which
is fixed to the tubular steering pillar and turns with it. This cross head may be
and by preference is made so as to also serve as the clip to clip the tubular
steering pillar. The cross head is made in the form of a socket with two projecting
arms to which the ends of the two side strengthening tubes are respectively fixed.
The said socket part fits on the tubular bush part of the collar which forms the
top race of the ball bearing head, and this socket is split longitudinally so as to
clip the tubular steering pillar.

Certain Improvements in Safety Bicycles and other Velocipedes.
I, ROBERT WALKER SMITH, of The Eadie Manufacturing Company, Limited,
of Hunt End, Redditch, in the County of Worcester, Cycle Manufacturers'
Manager, 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:-
This invention has reference to safety bicycles tandem bicycles and other
velocipedes and this invention consists of the herein described improved con-
struction of the front fork and steering head so as to strengthen the same and
effectually prevent their breaking through the vibration and strains to which these
narts are subjected when the machine is being ridden.

I will describe my invention by referring to the accompanying drawing on
which
Fig. 1 is a side view of a safety bicycle with the front fork and steering head
strengthened in accordance with this invention;
Fig. 2 is a side view on an enlarged scale of the front fork and steering head of
the said machine;
Fig. 3 is a front view of the said front fork and steering head; Fig. 4 is a
sectional plan of the same on line X X of Fig. 3 and
Fig. 5 is a sectional elevation of the upper part of the said steering head on an
enlarged.scale.
The same letters of reference indicate the same parts in all the figures.
In carrying out my invention I strengthen the usual front fork A' A' by fixing
thereto two side tubes marked respectively B' B' which extend from the wheel
axle C to the top of the steering head D. Thus each arm of the front fork is
strengthened by being made of two tubes side by side preferably of corresponding
shape, that is to say, the tubes A 'B' form one side of the fork and the
two tubes A B form the other side of the fork. The outer strengthening
tubes B B are at their lower ends 1 fixed to the lower ends a of the
fork A A where the axle C passes through. 'The outer tubes B¹ B' pass
through holes e in and are brazed and connected to the cross bar or fork
crown E which is fixed to the lower end of the steering tube G in the bicycle
head D and the upper ends 6 of the outer tubes B' B' are connected to the cross
head F which is fixed to the upper end of the said steering tube G and turns with
it. "This cross 'head F is made with two projecting arms f¹ which are shouldered
down at their extreme ends and threaded through eyes in the top ends of the
tubes B B the latter being secured 'by the nuts g g which are screwed on to the
ends of the arms ff. The central portion of the cross head F is made to clip
the tubular steering pillar G and takes the place of the usual socket which fits on
the tubular bush H of the collar h which forms the top race of the ball bearing
head this socket H being split 'longitudinally as usual to clip the steering tube G
and the steering handle tube I which fits in the usual way within the tubular
steering tube G.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
-claim is :-
1. Strengthening the front fork and steering head of a safety bicycle or other
front steering velocipede, by the 'two extra tubes B₁ B' arranged at the sides of the
fork and extending from the lower ends of the front fork to the top of the steering
head and fixed to the front fork and fork crown and to a cross head on the steering
tube, substantially as hereinbefore described and illustrated by the accompanying
drawings.
2. The combination with the front fork and steering tube of a safety bicycle or
other frout steering velocipede of the two extra strengthening tubes B B arranged
at the sides of the fork and extending from the lower ends of the said front fork
. to the top of the steering head, the fork crown plate. E made to embrace and fixed
-to said extra tubes and the cross head Ffixed to the steering tube and to the upper
ends of the side tubes B' B' all substantially as hereinbefore described and
illustrated by the accompanying drawings.
