Improvements in or connected with Velocipedes.
I, ALFRED EBENEZER MAVOR, of The Northfleet Engineering Works, North-
fleet, in the County of Kent, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention refers to improvements in that type of velocipedes described
in British Patent Specification dated 13th August 1895, No. 15230 granted to
Birger Ljungstrom and wherein in addition to the seat for the person riding
and driving the machine, there is provided a seat located in the front of the
machine, for the accomodation of a passenger, and in the machine described
in the said specification, such front seat for a passenger was provided with
springs which latter were fixed directly to the fraine of the machine.
Now in practise it has been found that this direct fixing of the front seat
to the frame of the machine is inconvenient in that the seat or carriage of
the passenger or person carried is not caused to face the direction of travel.
when the vehicle is in the act of passing around a curve, and the object of this
invention is to so construct and arrange the parts whereby when the steering
wheels are operated, the seat or carriage for the passage will be turned to a proper
angle.
According to my invention upon carrying springs which are fixed to the
framework of the machine, I mount a horizontal frame, which is fixed to the
said springs, and such frame may be composed of tubular metal and may be
rectangular in plan or of other suitable form, and the horizontal frame has a
longitudinal bar or tube extending centrally across same and forming a part of
such frame.
Upon and about centrally of the cross bar or tube of the horizontal frame
there is fixed a ball bearing arranged with a vertical axis, and the said bearing
carries an upper frame, capable of partially revolving relatively to the lower
fixed frame, upon the said ball bearing, the upper frame being further supported
by parts which bear upon the side parts of the lower frame. The upper frame
may be formed with four or more radial arms, the extremities of which on their
under sides carry bearing pieces which rest upon the outer members of the
under frame upon which they slide as the upper frame is partially turned upon
its central ball bearing.
The seat or carriage for the passenger is located upon the top of the upper
frame, to which it is secured by bolts or screws or by other suitable means, and
the said seat is connected to the steering mechanism by links, flexible cords, or
the like, in such manner that when the steering handles are operated the said
seat or carriage with the passenger thereon or therein is turned to a proper
angle according to the curve around which the vehicle is passing.

I, ALFRED EBENEZER MAVOR, of The Northfleet Engineering Works, North-
fleet, in the County of Kent, 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 :-
This invention refers to improvements in that type of velocipedes described
in British Patent Specification dated 13th August 1895, No. 15230, granted to
Birger Ljungstrom and wherein in addition to the seat for the person riding
and driving the machine, there is provided a seat located in the front of the
machine, for the accomodation of a passenger, and in the machine described
in the said specification, such front seat for a passenger was provided with
springs which latter were fixed directly to the frame of the machine.
Now in practice it has been found that this direct fixing of the front seat
to the frame of the machine, is inconvenient, in that the seat or carriage of
the passenger or person carried, is not caused to face the direction of travel,
when the vehicle is in the act of passing around a curve, and the object of this
invention is to so construct and arrange the parts, whereby when the steering
wheels are operated, the seat or carriage for the passenger will be turned to a
proper angle.
In order that my invention may be readily understood, I will describe same
with reference to the accompanying drawings, whereon Fig. 1 shews in sectional
side elevation so much of a velocipede, or what I may call the "cab-cycle" of
the type described in Patent Specification No. 15230/95, aforesaid, as is necessary
to illustrate the application of my present invention thereto. Fig. 2 is a
plan view of the front part of the machine shewn at Fig. 1, the passenger's
seat or chair being removed in order to illustrate the turntable carriage for
same.
Fig. 3 is a vertical longitudinal section of the seat mounting, drawn to a
larger scale than the previous figures, and Fig. 4 is an inverted plan view of the
rotary frame detached.
Similar letters of reference refer to like parts in all the figures of the drawings.
According to my invention I fix upon the forward part of the framework of
the machine, a frame A, which may be composed of tubular material, and is
circular in plan. Such a circular frame A may be conveniently fixed upon the
lower longitudinal tube B of the framework, and supported laterally by being
fixed upon the members B of the framework, which extend from the tube B
to the lower ends of the steering socket tubes C.
The socket tubes C extend upwards and incline rearwards, and are connected
together by the tube D, from which the tube E extends to the rear framework of
the machine. Fis the saddle pillar to support the saddle for the rear rider, who
drives the machine.
Above the circular frame A, there is an upper frame, forming a turntable G,
and the latter may be conveniently constructed as a cross framework, being
provided centrally upon its under side, as shewn by Figs. 3 and 4, with a ball
race G¹.
Supported from the bracket containing the tubes B and B of the framework,
Fig. 3, is the fixed half of the ball race, and a pin extends through the ball
race G of the turntable G, from the lower ball race, whereby a ball bearing
is provided upon which the turntable G may be revolved.
Upon the under surfaces of the arms of the turntable G, rollers H are carried,

page_text: to bear upon the fixed circular frame A, the said frame A thus forming a track
to support the turntable laterally, while the central ball-bearing carries the
greater part of the weight.
Upon the arms of the turntable G, I fix springs J by which the seat K for
the passenger is carried.
It will now be understood that the seat K, together with the turntable G,
is capable of being partially revolved, relatively to the lower fixed frame A, and
in order that the seat K with the passenger thereon may be turned to a proper
angle according to the curvé around which the vehicle is passing, I provide
means such as links flexible cords, or the like, by which the seat K may be
connected to the steering mechanism, and turned to a proper angle by the
action of the said steering mechanism.
In the drawings I have shewn an example of such connecting means, con-
sisting of flexible connections, such as cords or chains M M, each being connected
at one end to the turntable G, and extending respectively to the lower ends of
the steering tubes. Upon each of the said steering tubes N N, I fix a pulley
or segment L L, upon the peripheries of which the ends of the connections M M
are fixed, so that upon the steering tubes N N being turned, by means of the
steering handles NN¹, the turntable G and the seat will also be turned to the
required angle.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed I declare that what
I claim is
1. In the type of velocipede referred to in the foregoing specification, pro-
viding a circular track fixed upon the framework of the machine, a turntable,
provided with bearing rollers and pivotted centrally, concentrically to the said
circular track, the bearing rollers running upon the circular track, the turntable
being provided with springs upon which the seat is supported, and connecting
means from the steering gear to the turntable or seat, whereby the movement
of the steering handles is so imparted to the seat as to turn the latter in the
direction of the curve around which the vehicle may be travelling, substantially
as set forth.
2. In the type of velocipede referred to in the foregoing specification, a circular
track fixed upon the framework of the machine, a turntable provided with a
central ball bearing, supported by the frame of the machine, concentrically with
the circular track, and bearing pieces or rollers carried by the turntable and
running on the track, springs on the turntable upon which the seat is supported,
and flexible connections from the turntable to the steering mechanism to turn
the seat by the motion of the steering mechanism to face the direction in which
the vehicle may be travelling, substantially as described.
3. The arrangement and combination of parts composing my improvements in
velocipedes, constructed and acting substantially as, and for the purposes, described
with reference to the accompanying drawings.
Dated this 12th day of July 1899.
