IMPROVEMENTS IN THE CONSTRUCTION OF VELOCIPEDES to be as follows
Year: 1885

page_text: I THOMAS HARRISON LAMBERT of Yew Tree Avenue, Carrington in the County
of Nottingham, Hosiery Manufacturer do hereby declare the nature of the said
invention for "IMPROVEMENTS IN THE CONSTRUCTION OF VELOCIPEDES
to be as
follows:-
"
This invention consists in a novel manner of constructing tricycles or other
velocipedes, particularly those suitable for two riders abreast and in the means of
converting the same into a safety bicycle at will.
According to this invention I may first construct a bicycle arranged to be driven
by the back wheel, preferably made the larger, by chain or band from hub and
spur wheel actuated by usual treadlo supported in suitable bearings attached to
frame placed between the front and back wheels, and steered by the front wheel-
preferably made the smaller-by handle attached to fork in which the said front
wheel is held. This fork turns in suitable sockets or eyes in frame, and is placed
at a convenient angle to bring the handle in the best position for hands of rider..
A third wheel of same diameter as the larger of the other two, carried in a
suitable separate frame is attached parallel to the other, by the frame to the other
frame, by cross stays or rods having shoulders and screw ends and nuts or other
known means that will admit of easy removal when required, suitable sockets
being made in the frames for the ends of the cross stays; or one end of the stays
may be rigidly fixed to the one wheel frame.
This third wheel is driven separately in the same manner as the other large
wheel by one of the riders.
The two saddles are arranged abreast to the frames preferably rather over the.
large wheels and suitably for the feet of the riders to work treadles.
"
By this manner of constructing a tricycle with the other known and usual parts
I am able to make one for two riders sitting abreast, of the kind known as
Sociables" much lighter and narrower than can now be done when made in the
usual way, and capable of much better propulsion, and having the advantage of
only running in two tracks and also capable of being quickly changed into a safety
bicycle, and by the addition of another small wheel to the one wheel frame, for
which purpose the latter may be suitably formed, into two safety bicycles.

I THOMAS HARRISON LAMBERT of Yew Tree Avenue, Carrington, Nottingham
Hosiery 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:―
"
"
This invention consists in a novel manner of constructing tricycles or other
velocipedes suitable for two or more riders abreast usually termed 'sociables
principally as regards the arrangement of the seats, and in the means of changing
such tricycles into a safety bicycle at will.
To enable my invention to be clearly understood I will proceed to describe the
same by aid of the accompanying drawings in which the same letters of reference
are used to denote corresponding parts in all the figures.
Figure 1 is a plan view of my improved "sociable" tricycle complete.
Figure 2 plan view of same disconnected.
Figure 3 side view of detached safety bicycle.
Figure 4 side view of an auxilliary driven wheel and frame for same.
Figure 5 side view of "sociable" complete according to this invention.
a is back or driven wheel of safety bicycle part, b driven wheel of an auxilliary.
part, c front and steering wheel of bicycle part, d, framo of same, e frame of
auxilliary part, f, f, spur wheels on axles of driving cranks, suitably mounted to
frames d, e; hh driving bands or chains, i, k, cross stays to connect the bicycle
part to the auxilliary frame and wheel to form a "sociable"; 1, sockets for ends of
cross stays i, k; m steering handle of bicycle part, n fixed handle of auxilliary part
represented straight in figures 2 and 4 and necessarily bent round in figures 1 and 5
p, eyes for stem g of steering handle to turn in.
According to this invention I provide a bicycle as represented at figure 3
arranged to be driven by the back wheel-preferably made the larger-by chain
or band h, from hub and spur wheel f, actuated by usual treadle arrangement
supported in suitable bearings attached to frame d, placed between the front and
back wheels, and steered by the front wheel c-preferably made the smaller-by
handle m, connected to stem q of fork in which the wheel c is carried. The stem q
turns in suitable eyes p, on frame d, and is placed at an angle to bring the handle
in the best position for hands of rider. A third or auxillary wheel b, of same
diameter as a, carried in a suitable separate frame c is attached parallel to the other
by the frame e, to the other frame d, by cross stays or rods i, k, having shoulders
and screw ends, and nuts or other known means to secure same that will admit of
easy removal when required: suitable sockets 7 being arranged in the frames do,
for the ends of the cross stays; or one end of the stays may be rigidly fixed to
the auxilliary frame e; or the stay i may be made to form part of it and bent
round as represented in figure 1.
The driven wheels a and b are driven separately in the same manner and as
before described by each of the riders. The two saddles are arranged abreast and
suitably connected in the usual way to the frames, preferably rather over the larger
wheels, and convenient for feet of riders to work treadles.

page_text: It will at once be understood from the above description, and by reference to
the drawings that the salient feature of this invention consists in placing the seats
rather over or in front of the driven wheels instead of between them as has hitherto
been done in "sociables"; and also that various modifications will readily suggest
themselves to any capable engineer in the mode of constructing a "sociable to
facilitate placing the seats over or in front of the driven wheels without departing
from the main principle of this invention viz:-the improved arrangement of the
seats, as herein before described and represented in the accompanying drawings.
By constructing a "sociable" tricyle-particularly as regards the position of.
the seats-as herein before described with the other known and usual parts I am
able to make one much lighter and narrower than can be done as now made, and
possessing the advantage of running in two tracks, and also capable of being
quickly changed into a safety bicycle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I would state that
I am aware that it has been proposed to connect two bicycles of the usual class
together in such manner that they can be disconnected at will, and in such con-
nected bicycles the riders sit over the driven wheels which are driven direct from
the foot and steered by such driven wheels in the usual way of ordinary bicycles;
but what I consider novel and declare that I claim is
1. In velocipedes of the class known as "sociables," arranging the seats rather
over or before the driven wheels when such wheels are driven from treadles
substantially in the manner hereinbefore described and represented in the accom-
panying drawings.
"
2.-Connecting an auxilliary wheel and frame fitted with means for driving
wheel, to a bicycle of the class known as safety" to form a tricycle sociable,
substantially as hereinbefore described and represented in the accompanying
drawings.
