GEORGE SCRUTON Cycle Agent & Repairer Bicycle House Normanton Yorks, do
hereby declare the nature of this invention to be as follows:
By placing a piece of steel or iron across the mud guard of hind wheel perpendicular
from the centre of the wheel bringing the said piece of iron down on each side to the
cone pin ends, and then bent back at right angles some inches having slots at
the ends, at the angles holes to go on the cone pin ends and fastened on
by the existing screws & nuts. The top of the above named iron over mud
guard supporting the seat or spring stayed from the front seat pillar. The
additional adjustable handle bar being placed on spring or attached to front seat pillar.
The lower ends of the before named Iron with slots being provided to connect two
links carrying triangular fork shaped bars one on each side of machine the said bars
being hung at the back ends with the above named links the front part near the ends
of the bars being placed on ordinary pedal pins on cranks and carrying the fore pedals
the other arms of same being at right angles rising some inches and having adjustable
sliding pedals the fore pedals describing an oval the back ones having a reciprocating
and pear shaped movment together more effectually contributing a continuous rotary
motion.

Attachment Applicable to Existing
GEORGE SCRUTON Cycle Agent & Repairer Bicycle House Normanton Yorkshire,
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 first part of the Invention consists of providing a second seat S to be placed
behind the foremost rider by adding two upright rods R one on each side or
otherwise bending one rod over the back wheel of a Safety Bicycle so as to form
two uprights one on each side and to carry the second seat in a manner adjustable
in height or otherwise the said uprights to be fixed on the cone pin ends behind
the existing nuts and bent back at right angles on each side or otherwise providing
two brackets B on the said pin ends one on each side to carry the said uprights,
but in cycles or Safeties where the said nuts do not exist, to be fixed where and
in such a manner to answer the same end. The brackets for ordinary Safeties
being about 6 inches long made of strong sheet metal and at one end having a
hole similar to the ordinary washers and are fastened behind the existing nuts in the
same manner, near to the forenamed holes a little more to the rear end a little
larger hole being made through sideways, through this is placed a stud D and the
inner end, betwixt the wheel and bracket presents a suitable hole upwards, so that
the rod can pass through and be adjusted to the proper height of the rear rider.

page_text: on the opposite end of the forenamed stud a strong and flat nut F is placed on
the outer end to draw tight on lock the upright after being adjusted the remaining
part of each bracket rearwards being cut with a long slot H hole for the bearing
the forenamed bearing when made plain or otherwise, being screwed on the
outside and placed through the slot hole, crossways, and by placing a nut on each
end is made adjustable backwards, forwards, inwardly or outwardly. The two
bearings described being necessary for the next part of my Invention (which
answers equally well for footrests and steps for the rear rider) which consists of
providing one link L on each side suspended from the bearings before named
each link having a pin P pass through the bearings above named and suspended
from these are also similar pins which pass through similar bearings at the lower
ends of the links, on the outside of the lower bearings provision is also made for
adjustment inwardly or outwardly.
The next part of my Invention being, two triangular forked shaped bars Tone
on each side of a Safety the rear ends being fixed on the bearings before named
on the lower ends of the links E. The foremost ends of the bars or near to,
being placed on ordinary pedal pins or otherwise fastened to the inner ends of the
pedals; betwixt the cranks and the pedals, by the existing pins passing through
the rubbers of the pedal or otherwise, the foremost ends of the bars 1 just specified
being about of an inch thick and a little longer than the width of the pedal
(where fastened by the pedal rubber pins) and then at the outside behind the
pedals, bent a little towards the outer end of the pedal and connected to the
remaining or the rear part of the bar, by a joint J so as to be more easily
removed also to allow for any inaccuracy in the machine but at the same time
causing the pedal to be added to the bar and act as one complete bar, still carried
by the pedal pin which we will call the fulcrum, the front part of the pedal or
bar alone being used as such, which has the effect of adding one half of the width
of pedal to the length of crank leverage but in the upward part of the circuit,
or on the return of the crank backwards, it places the end of the bar the width
of the pedal nearer the centre of the crank axle thereby causing the end of the
bar to move eccentrically round the crank axle. The other arms A forming the
triangles being two uprights riseing some inches from the lower or longitudinal
part of the aforesaid bars carrying the two adjustable 2 pedals provided for the rear
rider, the fore parts of the pedals or bar moving in an eccentric manner and the back
ones having a reciprocating and pear shaped movement together more effectually
contributing a continuous rotary motion. The other part of the Invention being a
stay rod Z or spring connected to the seat pillar carrying the handle bar and also.
staying the seat of the second rider on the upright rods.
The advantages I claim for the foregoing Invention being to enable an adult to
take, up a juvenile behind an ordinary Safety or other Cycle and at the same time the
Child being equally accomodated with the means of propulsion. It is otherwise
advantageous because the Child travels the same speed as the Adult not necessitating
the trouble of halting and other annoyances as in the case of a child having a separate
machine another advantage offered being that the saddle and handle bar of the rear
rider also the rod or spring being on a level are well suited for taking samples for
Travelers & Luggage for Tourists at the same time affording the extra amount of bar
leverage to propel the extra weight. It is also advantageous because of the attach-
ment being alike changable from one Safety to another being also adjustable. It can
also be used by two juveniles most advantageously because of their weight being so
much less and the front end of the bar being more suited in offering means to raise
the pedals and without the disadvantages of long cranks it enables two Juveniles to
keep pace with an Adult. It being also an attachment does not cost the same by rails
that a Childs Cycle would but can be taken without charge, a childs machine singly
costing equally as much as an Adults and might exceed the value of the machine. In
addition to the foregoing the longitudinal bars and links with suitable brackets added

page_text: behind the front forks of large ordinary Bicycles may be used with equal advantage
for one rider giving longer throw of crank same as before described also enabling a
small man to ride a large Cycle.
