Improvements in Bicycles, Tricycles, and similar Vehicles.
I, JAMES PARR of 61 Friar Lane, Leicester, Tricycle Manufacturer, do hereby
declare the nature of this invention to be as follows:-
An objection in using a bicycle or tricycle, is that the vehicle is subject to
vibrations caused by the unevenness of the road, or by the wheels in surmounting
small obstacles; these vibrations are communicated through the steering handles
to the steerers hands. Now my invention is designed to remedy this objection, and
the steering bar which is the subject of this specification is constructed as follows.
A horizontal bar or tube is rigidly connected at the centre of its length to a bar
or tube fixed at any convenient angle, the lower end of which bar or tube is forked
to receive the steering wheel. Carried by the horizontal bar or tube and either
within or without, is another bar or tube which is free to revolve a portion of a
circle, the revolving bar or tube carries a projecting arm which engages with a stop
on the horizontal bar or tube when required, and is held to the stop either by metal
springs or elastic cushions carried at the upper end of the fork. The revolving
bar or tube may be made either in one continuous length, or two lengths meeting
at the centre of the horizontal tube. At the outer ends of the revolving tube or
tubes are fixed the steering handles either bent at right angles or any other con-
venient angle to the same; or each handle may be carried by a crank and so be
parallel to the steering bar. By the above it will be seen that the steering handles
revolve vertically a portion of a circle, the centre of which is the centre of the
horizontal steering bar; and that the springs or cushions receive and absorb the
vibrations which by these means are not imparted to the handles.
Dated this 11th day of January 1887.

Improvements in Bicycles, Tricycles, and similar Vehicles.
I, JAMES PARR, of 61 Friar Lané, Leicester Tricycle Manufacturer, 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 :-
An objection to using a Bicycle or Tricycle is that the vehicle is subject to
vibrations caused by the unevenness of the road and by the wheels in surmounting
small obstacles; these vibrations are communicated through the steering handles to
the steerers hands. Now my invention is designed to remedy this objection and
will be best described by the accompanying drawing, in which Fig. 1 is a lateral
sectional elevation, Fig. 2 an elevation at right angles to Fig. 1, Fig. 3 a plan of
Fig. 1, Fig. 4 a sectional plan of Fig. 2 through the line a. b. having the upper
part removed, and Fig. 5 a reduced plan of steering bar complete showing
handles I. 1. In these five views A is a portion of the steering tube or bar of a
bicycle or tricycle, which is forked at the lower end to receive the steering wheel,
the upper
end of A is formed into a tee-piece through which is secured the horizontal
tube B which is made of sufficient and necessary length.
•
Through B and free to revolve within the same passes another tube or bar C
which is made of sufficient length and cramped or curved to a convenient form to
carry the handles for steering as shown in Fig. 5.
These handles revolve together in a portion of a circlo the centre of which is the
centre of the tube or bar and in combination with a projecting arm D which is
secured to C and passes through a slot in the upper part of A.
The arm D engages with the upper end of the slot as shown in Fig. 1 thus acting
as a stop to arm D and the steering handles when required. The arm D is covered
by a casing E which may be secured to A by screws F. F. F as shown.
At the lower part of E is carried an adjusting screw G between G and the head
of the arm D is inserted.a metal spring or elastic cushion H the pressure from which
against D may be adjusted by the screw G thus absorbing the vibrations produced
on A and which would be carried to the steering handles but for the intervention of
the spring or cushion H.
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 :-
1. The cramped or curved steering handles which revolve in a portion of a circle
in combination with the arm projecting from the steering bar through a slot in the
frame of a Bicycle or Tricycle, and engaging with the upper end of the same slot
when required, substantially as shown and described.

page_text: 2. The projecting arm from the steering bar engaging with a metal spring or
elastic cushion, the pressure from which may be adjusted by a screw, substantially as
shown and described.
3. The casing or guard to carry the adjusting screw and enclose the arm and
spring or cushion in combination with the cramped or curved steering handles,
substantially as shown and described.
