Improvements in Anti-vibrating Cycles or Velocipedes.
1, Hugo AUGUSIL BICKER of Godwith Cottage, Blaenavon in the County of
Monmouth Metallurgical Chemist, do hereby declare the nature of this invention to bo
as follows
1
The object of this invention is to provide an improved method of lessening o
removing vibration in cycles by means of a spring frame constructed as follows
The handles saddle and crank axle are kept in position in the usual way by a rigid
fame of any form of construction The front part of this fiame m or on which the
sieering rod acts may be connected to the head of the fork of the front wheel by two
connecting rods parallel to one another and hinged to the head of the front fork, and to
the sand fame so as to form a parallelogram with the frame and the head of the fork
Thus we have a vertical parallelogram every angle of which is formed by hinged
Joints The movement therefore is up and down and when pressure is applied from the
handles or any other part of the frame downwards, there is a tendency to alter the
angles of the parallelogram and consequently alter the distance between the sides of
the parallelogiam and especially between the head and frame This is prevented to a
certain extent, by a spring which can either be a tension spring or a coiled spring.
acting upon the sides of one angle, or a pressure sping on the top of the parallelogiam
The steering is effected by means of rods connecting the forks of the font wheel to
the steering 10d The ends of these rods are swivelled turning in any direction, their
centies being on the line or prolongation of the line, drawn through the axis of the
hinges of the respective sides that is to say the swivel on the steeing iod will be in
alue with the hinges on the frame
Instead of two connecting rods with four hinge joints forming a parallelogiam as
before described, one hinge joint may be used on the frame with one connecting piece
joming the head of the front forks to the flame This connecting piece must be gid
to the fork head but joined by the hinge to the frame In that case the steering is
nearly the same as before described
In safety Bievoles the rear part of the frame on which the saddle is placed, is con-
nected to the centre of the rear, and to the diving wheel by a horizontal 1od hinged
at the rank axle
From a higher point on the jointed part of the frame is another hinged connecting
Tod and this is again hinged on to the back fork which itself is hinged to another fork
near the centre of the wheel so as to form a quadrilateral frame, the angles of which are
formed of hinges and are in such a position that by pressure from the frame down-
wards there is a tendency to change the angles of the quadrilateral and therefore alter
the distance between the sides, which is prevented to a certain extent by a sping
counteracting this movement
These arrangements can be used on any cycles of any form of construction
By the foregoing aangement I obtain the following advantages
(1) Complete isolation from metallic vibration
(2) The distance from the handles saddle and pedals does not vary except so fai
as is allowed by the saddle spring, consequently there is no loss of power
(3) The front fork can easily he constructed in aux position and diverted from the
vertical line to aux angle at the fancy of the manufacturer
In the vertical position straight and vertical steeling is obtained, giving no play and
consequently no side shipping of swerving

Improvements in Anti-vibrating Cycles or Velocipedes.
1. HUGO AUGUSTE BLOKIR of Godwith Cottage, Blaenavon, in the County of
Monmouth, Metallurgial Chemist, 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
"
15
This invention has for object the lessening or overcoming of vibration in excles or
velocipedes of all kinds, and it is also applicable to other vehicles mounted on metal
wheels such as chats for invalids and the like
It consists of a vertical spring frame interposed between the body or seat of the
ycle on vehicle, and the wheel or wheels, and in the case of bicycles is intended to
be chiefly used on the back wheel, which carries the greater part of the riders weight,
although it is applicable to the front wheel also in a more or less modified form as
hereafter explamed
Safety
I will now proceed to describe my mvention as shewn in the accompanying drawings
which Fig 1 (Sheet I) shews a
Bicycle with an ordmary V body, one
part of which, namely thevertical seat support is utilised as one side of my spring frame,
which forms altogether a quadrilateral or foursided figure composed of angular
curved or straight connecting rods of varying length, which are hinged or pivotted
together at or near the points of contact These four rods are lettered respec-
tively A B C D and then points of contacts, or jomis, are denoted by the letter
It will be seen that the joints are rigid in a lateral or horizontal direction but work
easily in the vertical direction, thus vielding readily to any pressure, of blow, caused
by the wheel encountering an obstacle on the road
In this vertical motion the joints are controlled by the tension spring E which
muav be made in QUEN of the well known forms of springs suitable for such a
purpose
The front wheel of the bicycle is shewn attached to the body by the bar or tube F.
the connection taking place at the joint G, as at the other wheel, and being controlled
by the spring S
The Fork-head H is hollow, and allows the spindle of the Fork to turn inside it for
guiding purposes
The steeling 1ods K are attached to a horizontal pm or plus pro-
jecting from the colla of the Fork 1,
Fig 2 (Sheet II) shews another mode of arranging my quadrilateral frame which
can be varied in many ways to suit the shape of the cycle body, without departing from
the pinciple In this case the short connecting rod A is placed near the axle of the
wheel and below B instead of above it as in Fig 1 The sping E is also differently
placed, but the action of the whole frame is precisely similar in both cases
Fig (Sheet II) shews the front of a safety bu vole body with a modification of my
quadilateral spring frame the handle socket and fork-head being utilised as two sides
of the quadrilateral
It will be seen that the fork-head His prolonged to afford space for the upper con-
necting rod A Below this is the lower connecting rod C and on either side are the
equivalents of the other rods B and D Inside the frame is the tension spring 1,
which as before stated controls the movement of the frame, and can be placed mauv
position suitable for that purpose
The effect of this arrangement is that on an obstacle being encountered, the distance
between the sides of the quadrilateral, and between the centies of the wheels and the
body of the machine on the seat thereof will be altered, and the tension spring will
yield somewhat till it recoils and draws the frame back to its normal position
consequence the vibration caused by contact with the obstacle is taken up by the
spring and does not affect the 11de

page_text: Having now particularly described and ascertamed the nature of my said Inven-
tion, and in what manner the same is to be performed 1 declare that what I
claim is
1 In cycles or velocipedes or other vehicles in which rigid or metal wheels are
employed, an arrangement of jointed connecting rods moving vertically on horizontal
pivots at or near then points of contact, in combination with a controlling Spring, of
pings the whole forming in connection with the body of the machine or indepen-
dently thereof, a quadrilateral spring frame to absorb the jar or vibration arising from
obstacles on the road on other causes as herem explained and set forth
2 In veles o velocipedes or other vehicles using rigid or metal wheels, the inter-
position between the body or seat and the axle on axles of the wheel on wheels of a
vibrating sping frame containing in combination some or all of the parts herem
described for the purpose of counteracting on minusing metallic or other vibration
as herem explained and set forth
