PROVISIONAL SPECIFICATION
Improvements in Cycles
I CHARIES BINKS Engineer Burton Lane York do hereby declare the nature
of this invention to bo is follows
My present invention is intended to strengthen the front part of cycles and is
accomplished as follows
Into the bottom part of the steering tube I insert a lining made preferably of
coiled sheet stecl This liner extends from about the bottom of the steering tube
upwards as far as may be necessary above the bottom row of ball bearings
1 he liner may be binzed, soldered, screwed pinned or driven into position in the
steering tube

CHARLES BINKS
I, CHARLES BINKS, of Burton Lane, in the City and County of York 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 present invention relates to cycles, and his foi its object to strengthen the
front part thereof more especially the steering tube and fork
It is accomplished as follows
Into the bottom part of the steering tube 1 inseit a lining made preferably of
coiled sheet steel This line extends from about the bottom of the steering tube
upwards as far as may be necessary above the bottom row of ball bearings
In the accompanying drawings
-
Figure 1 is a longitudinal section of the liner,
Figure 2 is a plan
Figure 3 the liner located in position in the steering tube ready for use
In these figures-
A is the liner or tube, B the steering tube, C the bottom row of ball bearing>
and D the steering fork The liner is made of coiled sheet steel, the number of its
coils being of course regulated by the strength required and its coils are by
preference graduated on the inside as shown at a in the sectional view, Figure 1,
ind by dotted lines in Figure 3 It will be seen that by graduating the coils of
the liner in this way, the liner at one end is tapered and its thickness gradually
reduced, while the full thicknes and strength of the liner is maintained at other
parts The object of forming the coils of the liner in this way will be obvious,
namely, that a steering tube ntted with a liner of one uniform thicknes throughout
might have a tendency to break off just at the point where the liner ended, this
tendency to break off increasing in proportion to the thickness of the liner
arrangement, therefore, of liner with graduated coils tapering to a
thickness at one end avoids the risk of the tube breaking at the point indicated

My
minimum

page_text: The liner formed as described is driven into the inside of the steering tube B the
length of the line being such that it extends from, say the bottom of the
steering tube upwards as far as may be necessary above the bottom low of ball
bearings C The liner or tube is held in place inside the steering tube by being
biazed, soldered, screwed, pinned or held in place by virtue of its resiliency, and
it is obvious that when thus fixed in place, it gently strengthens the front part of
the cycle, more especially the steering tube and fork
Having now particularly described and ascertained the nature of my said inven-
tion and 10 what manner the same is to be performed, I declare that what I
claim is
―
1 A cycle in which the inside of the steering tube is provided with a liner or
tube of coiled sheet steel, said liner being diven into position in the steering tube
and held in place therein by brazing, soldering, screwing, pinning or by virtue of its
resiliency
2 In a cycle having a steering tube, the combination therewith of a liner oi
tube of coiled sheet steel, the coils of said liner being graduated on the in-ide in
such a manner that the liner at one end is gradually tapered down to a minimum
thickness substantially as and for the purpose described
