A New Chain Adjustment and Fork End for Velocipedes.
WILLIAM SAMUEL HOWELL, 80, Summer Hill, Birmingham, Cycle Finisher, do
hereby declare the nature of this invention to be as follows:-
I first place some teeth in back fork end or plate and then I make a cog wheel
which is put on the axle of back wheel with teeth facing fork end so that you have
only to give back wheel locknut half a turn inwardly and place spanner or peg
wrench on cog wheel and turn it round when it will immediately adjust chain
doing away with all unsightly pins and nuts and making a very neat, compact and
efficient adjustment.
In bringing my new chain adjustment into practice in the first place the axle
is put into the hub of back wheel in the usual way, and I screw a locknut up the
axle, I then make a cog wheel of either iron, steel, or any other suitable metal and
put it next to the locknut with the teeth facing the back fork end. I then cut
same teeth in the back fork end or plate fixed to same to correspond with those on
cog wheel. I then fix a nut or any suitable thing at end of axle so that after I
have put either fats or drilled holes into side of cog wheel for spanner or wrench
you can work cog up and down fork end thereby getting a perfect adjustment.
When the above is made it will be found to be neat compact very effective and doing
away with draw back bolts and other unsightly nuts. The adjustment will suit
either the ordinary or D shaped fork ends.

A New Chain Adjustment and Fork End for Velocipedes.
I, WILLIAM SAMUEL HOWELL, of 175, New Spring Street, Birmingham, in the
County of Warwick, late of 80, Summer Hill, Birmingham, Cycle Finisher, 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 invention has for its object a new chain adjustment and fork end for
velocipedes, by which I obviate the projection of the unsightly adjustment pins.
and nuts while at the same time the adjustment of the wheel in the back stays can
be adjusted smoothly and quickly without the possibility of any friction.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a sheet of drawings upon which I have fully
illustrated the nature of my said invention.

page_text: Figure 1 is a section through the spindle shewing one of the back fork ends in
elevation,
Figure 2 is an end elevation of Figure 1.
Figure 3 is an end elevation of the back fork end with the spindle removed.
Figure 4 is an elevation of the toothed washer.
A nut
In carrying my invention into effect in connection with D shaped back fork ends
I form the teeth a¹ on the fork end A or its equivalent plate. The spindle C is
first placed in the hub in the usual way, and a lock nut screwed on to end of spindle
after which I provide the toothed washer B which is placed next to the lock nut
with the teeth 61 in position to engage with the teeth a' on the fork ends.
washer or block F is then mounted on the end of the spindle and having a flat face f¹
to bear against the side of the fork end and the spindle C is inserted in the fork
end with the block F within the tube and the teeth of the washer B engaging with
the teeth of the fork end on the inside the whole being secured by the lock nut E
suitable holes or flats being provided on the toothed washers B to enable them to
be readily turned when required for the purpose of adjustment. I may apply my
invention quite as effectively and simply in the case of ordinary plain fork ends and
the toothed washer adjustment can be fixed on either or both sides of the fork end
as may be desired .a. in the case of a plain fork end the toothed washer B may.be
either on the outside or the inside of fork end or I may provide teeth on both sides
of the one fork end, and have a toothed washer B both on the inside & the outside
of the fork end.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is: -
1st. A new chain adjustment and fork end for velocipedes consisting of the
toothed fork end in combination with toothed washer operated substantially as and
for the purpose herein set forth and illustrated.
