page_text: Improvements in Velocipedes.
We, WALTER PHILLIPS, of No. 34, Spon Street, Coventry, in the County of
Warwick, Manager to the Rudge Cycle Company Limited, and ROBERT WALKER
SMITH of No. 6 York Street, Coventry aforesaid, Machinist, 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 this invention is to obtain a velocipede that is comparatively safe from
the danger of capsizing or overturning and generally of an improved construction
and arrangement.
For this purpose we construct the machine with four wheels making two tracks
and we drive the two rear wheels through a differential gear of suitable construction,
which is by a chain wheel and chain connected with a chain wheel upon the axle of
which are fixed the usual cranks and pedals. The axle of the two rear wheels is
supported in bearings carried by a cross frame or carriage connected to the longi-
tudinal frame or backbone.
The pedal axle is mounted in bearings which are held or suspended by links pin-
jointed to the backbone or frame and the chain is strained or adjusted to the required
tension by means of rods or stays which are at one end hinged or pin-jointed to the
bearings or links and at the other end screw threaded and passed through holes formed
in brackets or offsets from the back of the cross frame or carriage, the required
adjustment being obtained by a nut or nuts screwing upon the ends of such rods
or stays.
The front or steering wheels are mounted upon short axles from which rise spindles
which work in long bearings carried by the front cross frame or carriago and to these
short axles are fixed the inner ends of short levers the outer ends of which are bent
or curved inwards towards the longitudinal frame or backbone and are coupled by
means of a connecting rod to which they are hinged or pin-jointed so that a differential
leverage or movement is imparted to the steering wheels by which means they are
caused to travel in circles or arcs of circles struck from one given centre.
connecting rod is, by a link pin-jointed thereto and by a universal joint connected to
a crank or offset from the steering rod or spindle which latter is mounted with
capability of turning upon or in a head or bearing carried by a short tube or support

And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed, aided by the accompanying drawings, more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1. is a side elevation of a velocipede constructed according to our invention
and arranged to carry a single rider.
Figure 2. is a plan thereof, and Figures 3. and 4. are respectively separate detail
views showing more clearly the method of mounting the front cross frame upon
its axle.
Figure 5. is a side elevation of a tandem machine constructed according to our
invention and arranged to accommodate three riders..
Figure 6. is a plan thereof Figures 7. and 8. aro detail views of a similar character
to those represented at Figures 3 and 4. Figure 9. is a part rear elevation and
Figure 10. is a part plan showing the connections from the steering spindle to the
connecting rod of the steering mechanism.
In the several Figures of the drawings like parts are indicated by similar letters of
reference.
Referring to Figures 1. to 4. a. represents the longitudinal framing of the machine
which is constructed at its rear end with a boss a' in which is fixed a cross tube frame
or carriage a¹ or the cross tube or frame a¹ might be otherwise rigidly connected to
the longitudinal frame a.
Projecting from the cross frame or.. carriago a¹ aro several brackets a³ carrying
bearings for the divided axle b. of the rear or driving wheels b* and connecting the
two parts of the divided axle b. is a differential gear b' of any suitable construction
which is by a chain wheel 6 carried thereby and a chain c. connected with a chain
wheel d. fixed upon the pedal axle d¹ which carries the usual cranks d and
pedals d³.
:
"
The pedal axle d' is mounted in bearings d which are held or suspended by links d³
hinged or pin-jointed to the longitudinal frame or backbone a. at d and the chain c. is
strained or adjusted to the required tension by means of rods or stays d' which are at
one. end hinged or pin-jointed to the links d or it might be to the bearings d* and at
the other end are screw threaded and pass through holes formed in two of the brackets
or offsets a³ from the cross tube or frame a¹ the required adjustment being obtained by
means of nuts d³ screwing upon the rods or stays d' and taking an abutment against
the offsets or brackets aª.
The front or steering wheels e* are mounted upon short axles e. from which riso
spindles e which work in long bearings e carried by the cross tube or frame f. and to
these short axles are fixed the inner ends of short levers e³ the outer ends of which are
curved or bent inwards and coupled by means of a connecting rod et to which they
are hinged or pin-jointed and the connecting rod e¹ is by a link one end of which is
pin-jointed to such connecting rod and the other end of which is furnished with a
universal joint connected to a crank or offset e from the steering rod or spindle e
which latter is fitted with steering handles es and, is mounted with capability of turning
upon a head or bearing f³ carried by a short tubular support f rising from a sleeve
fitted upon the longitudinal frame or backbone a.
This tubular support and the cross frame f. carrying the wheels e*
are all fixed

page_text: to the sleeve f¹ which fits upon the end a* of the longitudinal frame or backbone a.
with capability of partially revolving thereon and is secured in position by means of a
nut for it might be a key screwing onto or fitting into the end of the longitudinal
frame or backbone a.
By this construction the front or steering wheels e* are permitted to readily follow
the inequalities of the road and are capable of being easily removed together with the
cross frame and connected parts when desired.
The object of the peculiar formation of the lovers e³ is to cause the wheels e* in
steering to assume slightly different angles so arranged relatively to each other that
the wheels travel in circles or arcs of circles struck from one given centre.
The action of the steering mechanism is as follows:-
. The levers es being bent or curved inwards and pivotted to the connecting rod et it
follows, that when such rod is moved through the steering spindle and intermediate
connections so as to cause the vehicle to describe a curve the end of the lever e³
actuating that wheel taking the outside curve or circle will travel a less distance than
the opposite lever e³ and consequently the inside wheel will assume a greater angle
than the outside one.
By these means any tendency to the skidding of the wheels when the vehicle is
describing curves will be obviated.
The saddle.a is carried by a pillar a adjustably mounted in a standard a rising
from the longitudinal frame or backbone a.
In applying our invention to a tandem quadricycle constructed to carry several
riders as represented at Figures 5. 6. 7. and 8. we couple all the pedal axles d' by
means of chains c. and additional chain wheels d* in such manner that the combined
power of the several riders is conveyed from their several axles d' to the rear driving
wheels, rods or stays d' and connected parts being employed wherever necessary to
maintain the desired tension to the chains as previously described.
The main framing is provided with an extra pillar a to carry the additional
front saddle a and fixed handles a', and a detachable frame a*** to carry the additional
rear saddle a handles a' and pedal axle and connected parts is secured to the
main frame a. by means of a bracket fixed on the rear frame a*** and formed
with two lugs a provided with holes therethrough to fit onto studs a carried by
the cross frame a' the parts being securely bound together by nuts at.
The lower end of the detachable frame a*** is tied to the main frame a. by
means of a rod gl one end of which is secured to the frame a*** and the other
end of which is removably secured to the main frame a. by means of a nut or.
nuts..and a small guard or safety wheel g. is arranged at the rear of the
detachable frame a*** so that it is normally carried clear of the ground.
By removing the nuts a0 and 9 and uncoupling the rear chain the rear addi-
tional saddle and connected parts may be readily disconnected from and by the .
reverse operation connected with the machine when desired.
The sleeve carrying the cross frame f. is in this case mounted upon a stud
or short axle a fixed to the front part of the frame a. and the steering rod e
takes a bearing in, and its lower end passes out through, a vertical limb a** of
the frame a. and is by a crank or offset e connected with the link e and other parts
of the steering gear as described with respect to the previous figures.
We are aware that there are in existence. other machines arranged to carry
several riders and constructed with a device to enable the machine to follow the
inequalities of the road but such machines are formed with two driving axles and
corresponding driving wheels so that all wheels are driven but as each set of
wheels is independently driven and it is difficult for riders always to pedal in step
the machine is consequently caused to swerve when travelling fast...
Now according to our invention the riders all give motion to one, that is to
the rear driving, axle whilst the steering is effected by the front wheels by which
means we obtain steady driving and steering and the machine is entirely freed
from the danger of swerving from its course even when travelling at its greatest
speed..
