1, HENRY LAMING, of 80, Well Street, South Hackney, Oil and Colorman do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is to provide means for preventing the very objectionable
vibration which takes place with ordinary velocipedes, and which vibration arises from
the rigidity of the back bone, whereby the numerous motions arising from the
unevenness of the road are communicated to the back bone and other parts of the
velocipede.
In carrying out my invention, I form a knuckle joint in the back bone, or any
other part of the velocipede where it will be most effectual; and, in some forms of
velocipedes two or more of such joints may be provided for more effectually absorbing
the vibration of the wheels, or some of them.
I form shoulders to the knuckle joint, whereby the angle of motion, relatively to
the joint as a centre may be limited, and prevented from extending to one of danger.
I also fit to the two portions of the frame so joined, a powerful spring (preferably a
flat coiled spring). The power or force of this spring acts upon the jointed portions
of the frame so as to impart a tendency to retain the normal form of a rigid frame ;
but, upon vibration taking place, the spring yields sufficiently to allow motion to arise
at the joint, and thus effectually to absorb the vibration and render the riding easy
and comfortable.

page_text: 1 HENRY LAMING of 80 Well Street South Hackney, in the County of Middlesex,
Oil and Colorman, do hereby declare the nature of my said invention 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 my invention is to provide means for preventing the very objectionable
vibration which takes place with rear-driving safety velocipedes, and which vibration
arises from the rigidity of the back bone, whereby the numerous motions arising from
the unevenness of the road are communicated to the back bone and other parts of the
velocipede.
In carrying out my invention I form a knuckle or other suitable joint, in the back
bone, and in some forms of velocipedes, two or more of such joints may be provided
for more effectually absorbing the vibration of the wheels or some of them.
I form shoulders to the knuckle joint, whereby the angle of motion, relatively to
the joint as a centre, may be limited, and prevented from extending to one of danger.
I also fit to the two portions of the frame so joined, a powerful spring of any
convenient form. The power or force of this spring acts upon the jointed portions of
the frame so as to impart a tendency to retain the normal form of a rigid frame;
but, upon vibration taking place, the spring yields sufficiently to allow motion to
arise at the joint, and thus effectually to absorb the vibration and render the riding
easy and comfortable. The spring or springs may be used either in tension or
compression or otherwise, and may also be enclosed in cases, cylinders, or sleeves, to
protect the same from the weather.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1. is an elevation of a safety bicycle fitted with my improvements. Fig. 2 is a
plan view of the joint drawn to an enlarged scale, and Fig. 3 is a section on the
line y of Fig. 2.
a is the back bone, having a joint at upon or at which joint a limited amount of
flexure takes place. The distances between the shoulders dd and ee regulate the
angles of motion of the two portions of the back bone. c is a spring, the tension of
which may be regulated by screws and nuts, or other ordir..ry means.
This spring
tends to counteract the downward pressure, arising from the weight of the rider, and
its tension is so regulated that the back bone assumes a straight line, when in its
normal position.
It is obvious that in applying my invention to the various forms of velocipedes,
such as rear-driving safety velocipedes, the nature and position of the joint band

page_text: spring e and the number of joints and springs and other details, require to be modified
to suit the construction of the velocipede to which it is applied."
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 method of preventing vibration arising from the rigidity of the back bone of
velocipedes, by fitting the same with a suitable joint or joints and spring or springs,
substantially as hereinbefore described and illustrated on the drawings.
2. In rear driving safety velocipedes the application of the joint & in combination
with a spring, as shown at eas and for the purposes substantially as described and
shewn on the drawings.
3. The general construction combination and arrangement of joints and springs
applied to the back bones of velocipedes, together constituting my improvements in
velocipedes, substantially as and for the purposes herein before described and illustrated
on the drawings.
