Improvements in Velocipedes and other Road Vehicles.
I, JAMES BRINDLEY of 20 Eaton Street, Wilmorton in the County of Derby,
Hammer-man, 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 :-
The object of my said invention is to minimise the vibration experienced with
velocipedes and other road vehicles, and in order that my said invention may be
the more readily understood I have caused to be annexed to this Specification a.
sheet of drawings, the figures and letters of reference upon which will be hereafter
referred to.
"
I will first describe my invention as applied to a Safety" bicycle: Figure 1
being a side elevation of such a bicycle.
Upon the axles or spindles A. and B of the fore and hind wheels C and D and
upon both sides of the said wheels, I mount or fix blocks E adapted to slide up
and down the slotted extremities of the different parts of the frame of the bicycle,
or slotted bars or blocks adapted to receive and have secured to them the said
extremities and in the said slots 1 mount spiral springs F fitting around the
studs G and H upon the sliding blocks E and slotted bar or extremity of the frame
respectively.
:
It will be seen that by this means the whole of the weight of the rider and the
frame of the machine is poised upon and carried by the springs F which give
with the various inequalities of ground or surface over which the machine travels.
Instead of slotting the extremities of the frame as shewn in the case of the
fork I, I may construct a block as at J adapted to receive and have secured to it
in any desired manner the different parts K of the frame and supports L for the
mud guards, or any other portion desired.
Figure 2 is an enlarged elevation and Figure 3 an enlarged plan on line "a" ""
shewing my invention, the parts of the bicycle being in these two latter views
omitted..
I may employ spring or other packing as at M Figure 2 if desired to prevent
rattling or jarring upon the sudden return of the spring to the bottom of the slot.
It is evident that I may use this principle for supporting or poising the frames
or bodies of any velocipede or road vehicle by applying the sliding blocks E to
the axle or spindle or axles or spindles of the wheel or wheels upon or over which
the body or frame of the velocipede or vehicle may be placed, the said blocks
being adapted to slide in the slotted extremities of the frame or body of the
velocipede or vehicle or in slotted bars, blocks or devices adapted to receive the
said frame or body or the different parts thereof, the weight being taken by springs
as already described and illustrated.
Should the spring F become thoroughly broken and fall out of the slot the
studs G and H would bear upon each other and thus support the velocipede or
vehicle so as to avoid any serious accident therewith and in the case of velocipedes
the distance between these two studs would be adjusted so as to be less than that
between the tyres of the wheels and the mud guards or brakes so that the two studs
will meet before the mud guards or breaks touch the tyres.
I may form an opening N in the slotted extremity of the frame, bar or block
for the purpose of inserting the sliding block E without using screws or bolts and
nuts, the stud H having to be first bent out of the way. I may if desired make a
certain portion or portions of this slotted bar removeable for inserting the block E
and spring F but I prefer to adopt the method above described.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
The improved means of minimising vibration in velocipedes and other road
vehicles substantially as described herein and illustrated by the accompanying
sheet of drawings.
