IMPROVEMENTS IN VELOCIPEDES
Year: 1884

page_text: We CHARLES WHITCHURCH WASBROUGH of the City of Bristol in the County of
the same City Solicitor, and JOHN STROUD GWYER WILLIAM STROUD of Kingshill
House Knowle near the said City of Bristol Gentleman do hereby declare the
nature of our Invention for IMPROVEMENTS IN VELOCIPEDES to be as follows:-
The object of the Invention is to arrange parts in connection with a tricycle so
that the same may be readily converted into a sociable. For this purpose the
velocipede is arranged as a tricycle so that motion is obtained to the driving wheel
by means of the treddle operation by a chain wheel, a chain, which acts also on
another chain wheel on the hub of the driving wheel, all which separately
considered forms no part of our Invention but to convert the same into a sociable.
We apply an additional portion of axle and another bearing wheel outside of the
driving wheel with the additional seat for the additional rider and frame for extra
treddles and another chain wheel to actuate another chain wheel on the outside of
the driving wheel so that each occupant will then take part in the driving
operation of the same driving wheel and the instrument arranged as a sociable will
have four wheels one on each side of driving wheel and a steering wheel whilst as
a tricycle it will only be provided with three wheels a driving wheel and bearing
wheel in the same line and a steering wheel.
The additional parts for a sociable may be readily applied and removed when
desired.

Agent.

page_text: We CHARLES WHITCHURCH WASBROUGH of the City of Bristol in the County of
the same City Solicitor and JOHN STROUD GWYER WILLIAM STROUD of Kingshill
House Knowle near the said City of Bristol Gentleman do hereby declare the
nature of our Invention for IMPROVEMENTS IN VELOCIPEDES and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
The object of the Invention is to arrange parts in connection with a "tricycle,"
or velocipede adapted for one person to drive, so that the same may be readily
converted into a "sociable," or velocipede which may be driven by more than one
person riding thereon.
"
For this purpose the velocipede is arranged as a tricycle so that rotative motion
is obtained to the driving wheel by means of the treddles which operate by means
of a chain wheel upon a chain which again acts on another chain wheel on the hub
of the driving wheel or the mode of conveying the rotative motion from the
treddles to the axle or hub of the driving wheel may be of any ordinary con-
struction adapted to the purpose but all which separately considered forms no part
of our Invention. In order however to convert the tricycle or "single" machine
into a
" sociable machine or velocipede adapted to be driven by more than one
rider we apply an additional portion of axle and another bearing wheel outside of
the driving wheel or on the side thereof opposite to the bearing wheel generally
provided, together with an additional seat for the additional rider and an
additional frame for extra treddles and another or additional chain wheel to actuate
another or additional chain wheel on the outside of the driving wheel, which wheel
thus becomes a central driving wheel so that each rider will then be enabled to
take part in the driving operation of the same driving wheel and the apparatus
thus arranged as a sociable or velocipede to be driven by more than one rider will
have four wheels one bearing wheel on each side of the central driving wheel and
a steering wheel whilst when the additional parts have been removed and the
machine is used as a tricycle or single" machine, it will only be provided with
three wheels, a driving wheel and a bearing wheel on the same line of axis and a
steering wheel
<
The additional parts described adapted to fit the "single" machine for use as a
" sociable" machine may be readily applied to and removed from the "single"
machine when desired.
Having thus described the nature of our said Invention we will proceed by the
aid of the accompanying Drawings to describe the same more in detail in order to
the improvements being the better understood.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews the apparatus arranged as a "sociable" or velocipede adapted for
the use of more than one rider, Figure 2 shews the additional parts, for connection to
the "tricycle" portion in order to form a "sociable," separately, a indicates the axis
of the driving wheel b and chain wheels c and c¹. d is a bearing wheel carried by
a short arm or axis from framing a which forms the axis of the driving wheel b,
e is another chain wheel carried by a bearing e' attached to the part framing ƒ
which connects the steering wheel g by means of the fork g¹ and bearings g³ with
the driving wheel axle a. This chain wheel e is connected to and is driven by
means of the cranks e² e² of the arm es which has its bearings at e¹ and e³. The

page_text: chain h imparts motion given to the chain wheel e to the chain wheel c and
thereby to the axle and hub of the driving wheel b to drive the machine. i is the
handle lever for hand of the rider to rest on and j the break lever connected by
the rod to the break applied to the hub of the driving wheel b as in ordinary
machines of this description. k is a steering arm with handle for steering the
wheel g and thereby guiding the machine by the intervention of the usual rack
rod and arm k² attached to the fork g¹. is the riders seat.
We will now describe the additional parts which serve to enable the machine to
be used by two riders when combined with the parts described above. a¹ is an
additional length of axle or framing which is connected at a to the frame a by the
stem or spindle thereon passing into a hinged socket in the additional axle a¹ the
connection being retained by means of a screw, and this frame a¹ carries another
arm f which is connected at f³ to the socket there provided on the head of the
fork g¹ and the connection of this socket f³ to the arm f¹ may be secured by means
of a screw passed through said socket into a recess or groove around the end f* or
this may be otherwise attained. d¹ is an additional bearing wheel carried by a
short arm from the frame a¹. e* is an additional chain wheel carried by a crank
arm es which revolves in bearings el* upon motion being given thereto by means
of the treddle cranks e* actuated by the additional rider whose seat is at 11 and
whose handle levers are at . ¹ is an additional chain for imparting the motion
given to the additional chain wheel e* to the chain wheel c¹ applied to the hub of
the driving wheel b in aid of the driving.
"
"
To disconnect the additional parts and transpose the machine from a "sociable'
velocipede for more than one person to ride and assist in driving, into a " tricyclo
for one only to drive, all that is requisite is to remove the socket in the additional
axle a from engaging with the stem of the main axle a and the end or stem f* of
the additional arm f1 from the socket at f³ and to take away the chain h¹, or to
effect the reverse transposition the reverse mode of proceeding is adopted.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
The combination of additional parts with a "tricycle," or velocipede to be driven
by one rider, so that the same may be convertible into a "sociable," or velocipede
adapted to be driven by more than one rider, each rider operating on the central
driving wheel, in manner substantially as set forth.
