AN IMPROVED ARRANGEMENT FOR CARRYING A CHILD'S SEAT ON A TRICYCLE
Year: 1884

page_text: We, ALFRED HENRY CARTMALE, and WILLIAM DAY, at the Office for Patents
17 and 18 Southampton Buildings, in the County of Middlesex, Managers of
Public Companies, do hereby declaro the nature of our invention for "AN
IMPROVED ARRANGEMENT FOR CARRYING A CHILD'S SEAT ON A TRICYCLE " to be
as follows:-
This Invention has for its object an improved arrangement for carrying a child's
seat on a tricycle and has reference more especially to what is known as the
hay fork" pattern.
In these tricycles spoon brakes are commonly used, the brake rod oscillating in
a tube brazed to the back-bone.
We propose to utilize this tube in conjunction with our invention, or where this
tube is absent, to fit a hinged rod to the back-bone as its equivalent as hereafter
described.
We fit our seat preferably on two scroll springs, the ends of the springs being
secured by screwed bolts and nuts to two long parallel springs. These are made
straight for a considerable portion of their length and their ends are furnished with
clips, the other ends are bent round at an angle to the straight portion and are bent
at the extremities to form clips.
If desired these springs can be in two portions, one being slotted and secured to
the other by clamp nuts and bolts so as to render the spring capable of longitudinal
adjustment.
The parallel springs are tied together by cross pieces or struts.
The last named clips fit over the said brake-rod-tube or its equivalent the hinged
rod and so support the child's seat.
The hinged rod when used is preferably formed by arms having lugs at their ends
and having segmental portions attached thereto hinged one to the other and
furnished with a clamp screw so that it forms a collar to embrace the back-bone
which is opened to pass over the latter and then clamped up.
This arrangement can also be fitted to some other forms of tricyles inore especially
that known as the "Rover."
Footrests may be rivetted to the bottom of the seat and divided to clear the
backbone.

of Lancaster and WILLIAM DAY of 25 Overton Street Liverpool aforesaid,
Managers of Public Companies do hereby declare thature of our invention
for "AN IMPROVED ARRANGEMENT FOR CARRYING A CHIL T ON A TRICYCLE"
'
and in what manner the same is to bo performed to be partic
ascertained in and by the following statement:-
Ay described and
This invention has for its object an improved arrangement for carrying a child's
seat on a tricycle and has reference more especially to what is known as the
"hayfork" pattern.
In these tricycles spoon brakes are commonly used, the brake rod oscillating in
a tubo brazed to the backbone.
We propose to utilize this tube in conjunction with our invention or where this
tube is absent, to fit a rod preferably hinged to the backbone as its equivalent as
hereafter described.
We fit our seat preferably on two scroll springs the ends of the springs being
secured by screwed bolts and nuts to two long parallel springs or spring bars
These are inade straight for a considerable portion of their length and their ends
are furnished with clips, the other ends are bent round at an angle to the straight
portion and are bent at the extremities to form clips. If desired the springs or
spring bars can be in two portions secured to each other by screwed bolts or pins
Bo as to render the springs or spring bars capable of longitudinal adjustment.
The parallel springs or spring bars are tied together by cross pieces or struts.
The last named clips fit over the said brake rod tube or its equivalent the hinged
rod and so support the child's seat.
The hinged rod when used is preferably formed by arms having lugs at their ends
and having segmental portions attached thereto hinged one to the other and
furnished with a clamp screw so that it forms a collar to embrace the backbone and
which collar is opened to pass over the latter and then clamped up.
This arrangement can also be fitted to some other forms of tricycles such as the
"Rover."
Footrests may be rivetted to the bottom of the seat and divided to clear the
back-bone.
And in order that our invention may be understood and carried into practical
effect we have annexed to this specification the accompanying sheet of drawings
and now refer to the figures and letters of reference marked thereon.
In these figures Fig 1 shews an elevation of the arrangement fitted to a tricyclo
of the "Meteor" type.
Fig 2 a plan of same.

page_text: bars.
Fig 5 elevation of our seat arrangement adapted to a looped frame front steerer.
A is the seat, of any suitable variety.
BB¹ scroll springs supporting the same or other springs might be used,
OC¹ the long springs or spring bars.
D D' the extremities of same arranged for longitudinal adjustment.
The ends of D D' carry clips E E' arranged to clip over the bend F of the hay-
fork frame..
The other ends a G¹ of CC' are bent at an angle and carry clips H H' arranged
to clip on the spoonbrake rod tube I, or on its equivalent the hinged rod or tube
shewn in Fig 3, and formed by rods or tubes J J' with collars at their ends to
prevent the clips H H₁ slipping off, the said rods or tubes J J¹ being attached to
jaws K K¹ pivoted at L and one carrying a set screw M to clamp the rod or tube
on the backbone N.
Of course when the spoonbrake rod passes through a tube brazed or secured
to the backbone N this arrangement is not required, but it will be wanted if this
type of tricycle has band brakes as in more modern "Meteors," or for "Rover"
type machines.
In this latter case the child's seat must be put sufficiently behind the rider.
To adjust the length of the parallel springs or spring bars CC¹ we place collars
or clamps 0 0¹ on them and in which their ends and the ends of D D¹ enter,
screwed pins passing through the collars or clamps 0 0¹ to clamp the ends C C D D'
together at any desired position, by which means the seat can be adjusted to fit the
machine.
For a front steerer of loop-frame type we arrange our parallel springs or spring
bara C (see Fig 5) with clips E to clip the bottom of the loop frame P and the
otlier ends G³ with clips H to clip the footrests R(which in this case are equivalent
to the brake rod tube I or hinged tubes or rods J J on the rear steerer). The
springs or spring bars C³ can be made adjustable like that shewn on the rear-
steerer.
Where there is not a footrest on the front steering wheel head, we fit our hinged
rods or tubes J J¹ for the support purpose to the same.
In Figs 1 and 2 R R¹ are the child's footrests and C³ can carry the same if
desired.
It is desirable that the arrangement may have some degree of elasticity and so
we prefer to make CC DD¹ &c of material sufficiently elastic so as to counteract
vibration and we therefore designate such as "springs or spring-bars," though it
will be obvious they might be made of thicker material so as not to be so elastic or
non-elastic.
It will be seen that by our invention we use neither screws clamps or bolts to
secure the seat to the tricycle, it simply being clipped over the frame and the brake-
rod tube or its equivalent.
Having now particularly described and ascertained the nature of the said.
invention and in what manner the same is to be performed we declare that
what we claim is
Firstly. The improved arrangement for carrying a child's seat on a tricycle
consisting of parallel tied springs or spring bars, or beams C C C² C³ arranged
with clips at their ends to clip on the frame (without the aid of screws clamps or
their equivalent for the purpose) substantially as described and illustrated by the
accompanying drawings.
Secondly. Providing the springs or spring bars C C C C' with means for
adjusting the distance between the clips carried by the supporting ends of the
same substantially as described.

page_text: Thirdly. For a tricycle for the purpose of carrying one end of the improved
child's seat arrangement, the hinged rod or tube provided with clamping jaws or
'surfaces and clamp screw or its equivalent, so as to fit a backbone or other part
of the frame, when a brake rod tubo or footrest is not fitted, substantially as
described..
