We CHARLES HENRY GUEST and LOUIS BARROW both of 280 Broad Street,
Birmingham in the county of Warwick Engineers do hereby declare the nature of
this invention to be as follows:-
This Invention relates to an improvement in Velocipedes or Cycles by the application
of one or more spring Joints in the Framework for the purpose of reducing the
Vibration on the rider.
In carrying out our invention we make the Framework which connects the back
& front wheels in two or more parts and join the parts together by any suitable means
so as to form one or more moveable Joints parallel with the axles of the wheels the
said parts of the Framework being supported at or near the Joints by means of one or
more springs.

page_text: We, CHARLES HENRY GUEST and LOUIS BARROW, both of 280, Broad Street,
Birmingham, in the county of Warwick, Engineers, 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 relates to an improvement in velocipedes or cycles by the application
of one or more spring joints in the frame-work for the purpose of reducing the
vibration transmitted to the rider.
In carrying out our invention we make the frame-work which connects the back
and front wheels, in two or more parts and join the parts together by any suitable
means so as to form one or more moveable joints whose axes are parallel with the
axles of the wheels, the said parts of the frame-work being supported at or near the
joints by means of one or more springs.
In order to enable our invention to be fully understood we will describe how the
same can be carried into practical effect by reference to the accompanying drawing in
which figure 1 illustrates by way of example a side elevation of a bicycle constructed
according to our invention; figures 2 and 3 are respectively a side elevation and a
plan drawn to a larger scale of a portion of the bicycle shewing the form of joint
which we have found most advantageous for connecting together the parts of the
frame. Similar letters of reference indicate similar parts throughout the figures of
the drawing.
a, represents the front or forward part of the frame-work and b, is the front fork
of ordinary construction, to which the frame a, jointed by what is generally known
as a "Stanley" head and neck c, to allow the machine to be steered. d, represents
the back fork or rear part of the frame-work and e, the moveable joint by which
we connect it with the front part of the frame-work a, the axis of the joint being
parallel with the axes of the wheels f, and g, of the bicycle. h, represents the spring
by which the parts a and d of the framework are supported in their normal positions.
,, represent clips for securing the middle portion of the spring h, to the frame a,
and j, j represent eyes for securing the ends of the said spring to the back fork d, as
shewn clearly in figures 2 and 3. k, figure 2, represents a bearing formed in the
back fork d, for receiving the crank axle 1, which is constructed in the ordinary
manner. m, figure 1, represents a bent rod or tube which can be raised and lowered
telescopewise in the frame a, and n, represents a pressure screw for securing the said
rod or tube at any desired height. 0, represents the saddle secured in the usual
manner. The wheels and g, are mounted in their respective forks b, and d, in the
ordinary manner.
By this construction should the front wheel of the bicycle, whilst the latter is being
ridden, pass over a stone or the like, the rider instead of being shaken or jolted up
and down as in velocipedes of ordinary construction, is only caused to move back-

page_text: wards and forwards through a part of a circle of which the axis of the joint e, forms
the centre, while in the event of the back wheel passing over a stone, but little, if
any, inconvenience is experienced by the rider as the said back wheel and the rear
end of the back fork in rising merely pivot upwards on the joint e, and are caused to
return to their normal positions by the spring h, without affecting the other parts of
the bicycle.
Although we have described and illustrated our invention adapted to a bicycle it
will be obvious that it is equally applicable with slight modifications to other
velocipedes. Also we have shown and described a form of spring joint which we
have found to answer well in practice but we do not confine ourselves to this
construction of joint and more than one of such joints can be employed if required.
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 :-
1. Constructing the frame-work connecting the back and front wheels of velocipedes
or cycles in two or more parts connected together by moveable spring joints
substantially as and for the purposes herein before described.
2. The improved spring joint for connecting together the divided parts of the
frame-work of a bicycle substantially as herein before described and represented in
the accompanying drawing.
3. The improved bicycle hereinbefore described and illustrated in figure 1 of the
accompanying drawing.

In carrying out our invention we make the frame-work which connects the back
and front wheels, in two or more parts and join the parts together by any suitable
means so as to formi one or more moveable joints whose axes are parallel with the
axles of the wheels, and situated near to the treadle crank axis the said parts of the
frame-work being supported at or near the joints by means of one or more springs.
In order to enable our invention to be fully understood we will describe how the
same can be carried into practical effect by reference to the accompanying drawing in
which figure 1 illustrates by way of example a side elevation of a bicycle constructed
according to our invention; figures 2 and 3 are respectively a side elevation and a
plan drawn to a larger scale of a portion of the bicycle shewing the form of joint
which we have found most advantageous for connecting together the parts of the

of ordinary construction, to which the frame a, is jointed by what is generally known
as a "Stanley" head and neck c, to allow the machine to be steered. d, represents,
the back fork or rear part of the frame-work and e, the moveable joint by which
we connect it with the front part of the frame-work a, the axis of the joint being
parallel with the axes of the wheels f, and g, of the bicycle. h, represents the spring
by which the parts a and d of the framework are supported in their normal positions.
i, i, represent clips for securing the middle portion of the spring , to the frame a,
and j,, represent eyes for securing the ends of the said spring to the back fork d, as
shewn clearly in figures 2 and 3. , figure 2, represents a bearing formed in the
back fork d, for receiving the crank axle 1, which is constructed in the ordinary
manner. m, figure 1, represents a bent rod or tube which can be raised and lowered
telescopewise in the frame a, and n, represents a pressure screw for securing the said

manner. The wheels and y, are mounted in their respective forks b, and d, in the
ordinary manner.

any, inconvenience is experienced by the rider as the said back wheel and the rear
end of the back fork in rising merely pivot upwards on the joint e, and are caused to
return to their normal positions by the spring h, without affecting the other parts of
the bicycle.
Although we have described and illustrated our invention adapted to a bicycle it
will be obvious that it is equally applicable with slight modifications to other
velocipedes. Also we have shown and described a form of spring joint which we
have found to answer well in practice but we do not confine ourselves to this
construction of joint and more than one of such joints can be employed if required as
for instance with a tricycle with two rear wheels on separate frames. We are aware
that various arrangements of cycles have been heretofore proposed having either a
jointed backbone, or the frame divided into portions joined together with one or more
joints. Such arrangements have been defective, owing to the nature of the joint or
joints used and its or their position in relation to the various portions of the cycle,
but we wish it to be understood that we make no general claim to the principle
of preventing vibration in cycles by the introduction of joints or springs into the
backbone.
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 :-
1. Constructing the frame-work connecting the back and front wheels of velocipedes
or cycles in two or more parts connected together by moveable spring joints
the front part carrying the front wheel or wheels, steering handle and saddle, the
back part carrying the hind wheel or wheels and the crank axis being situated
close to the axis of the joint, substantially as and for the purposes hereinbefore
described.
2. The improved spring joint for connecting together the divided parts of the
frame-work of a bicycle substantially as hereinbefore described and represented in
the accompanying drawing.
3. The improved bicycle hereinbefore described and illustrated in figure 1 of the
accompanying drawing.
