WILLIAM HARRISON, Machinist, of 128, Portland Street, and 69, Hyde Grove,
Manchester, in the County of Lancaster. "IMPROVEMENTS IN VELOCIPEDES OF
Two OR MORE WHEELS, PART OF WHICH IS APPLICABLE TO OTHER VEHICLES."
The object of my Invention is to prevent the cross binding of ball bearings, cone
bearings, or parallel bearings; also to prevent the extra friction of the bearing by
the constant cross binding caused by the twisting of the forks of velocipedes; also
to enable the rider to raise or lower the handle bar of the velocipede; also to
enable the rider to steer more easily; also to ring or whistle an aların when making
a journey; also to secure the rubbers more firmly upon velocipede wheels; also to
make the spring more easy for tho rider.
I construct a ball and socket joint at the lower end of the front forks of the
velocipede; the socket I make either upon the upper cap of the bearing or at the
lower end of the fork.
The ball I make at the bottom end of the front forks or at the upper end of the
front wheel bearing cap, which oscillates with the twisting of the forks whilst the
bearings remain unaffected.
I construct an adjustable handle bar by making an eccentric disc at the centre
of the handle bar. I fix the handle bar out from the centre, which, when turned
round by the rider, moves it to any desired point of a circle, which may be stopped
by a spring and stud; I also make two links and place one end of each upon studs
at the T part of a velocipede head and put the handle bar through the other ends
of the links.
I make an arc toothed or with holes, and a spring and stud to secure the handle
bar at any point of the circle.
I construct at the top and bottom of the centre steering of a velocipede of balls
and Vand U grooves. This said centre steering is placed inside the head of tho
velocipede which is made conically by other makers.
I make an alarm for velocipedes which I secure to the handle bar and fork.
I construct a tube and place a slide therein vertically.; at the right angle of the
slide I fix a bracket, and I fix an excentric upon this bracket and a bell dome

page_text: opposite, and a small hammer underneath the bell dome, which is struck with the
revolving excentric actuated by a rubber wheel coming in contact with the
driving wheel of the velocipede by means of pressing at the top of the slide. The
rubber wheel is brought out of action by means of a spiral spring pressing against
the underside of the thumb, dome, or cheese head fixed upon the vertical slide.
I also construct the alarm for the vertical rotary slide with the small rubber
wheel fixed at the bottom end horizontally, and I fix the hammer or excentric at
the top end, over or opposite which I fix a dome with a small spring hammer
facing the inside of the dome; when the rotary vertical slide is pressed down it
brings the rubber wheel fixed at the bottom end in contact with the wheel of the
velocipede, which causes the rotary vertical slide to revolve, and so causes the
excentric or hammer to strike the dome or spring hammer; I also fix a fan to
the same frame and whistle as an alarm. I make a small flat or round spring with
a hole in the centre; the ends of the spring are either shaped like a barbod fish
hook, or only pointed at the ends and bent in a suitable form to grip or hold the
rubber tyers upon the velocipede wheels; I hold the said spring down by putting
the wire spoke through the hole, in the centre of the head of which holds the
spring rubber fastener firmly down to the bottom of the rim, tyre, or feloe.
I make a spring coiled at the top end and a boss of rubber placed in the centre
of the coil; I place the stud through the rubber, which lessens the vibration to the
rider.
