PROVISIONAL SPECIFICATION.
An Improved Method of Suspending the Bodies of Perambulators
or similar Vehicles.
I, CHARLES EDWARD COWTAN of 84 Aldenham Street, Somers Town,
London, N.W., Blacksmith, do hereby declare the nature of this invention to be as
follows:-
This invention refers to children's carriages which have their bodies suspended
on chains or springs from the handle bars.
In my method the suspension is effected by interposing between the end of the
body and the handle-bar, a short connecting rod in which is a pivot joint. This
pivot joint is constructed with the pivot-pin working in a slot, so as to allow for the
rise and fall of the body within a distance regulated by the length of the slot.
One end of this jointed rod is attached to the body, and the other to the handle-
bar or to a cross-bar between the two handle bars.
A tension or other spring of india rubber or some suitable metal is fixed from the
handle-bar to the arm of the connecting rod in such a position as to support the
body at the proper height. The play of this spring affords the necessary projection
against jar when the carriage is in use.
By this method side play is prevented while any desired amount of vertical
elasticity is obtainable.
There is also less strain on the body and handle-bars than by the method now
in use.
Dated this 17th day of October 1892.

COMPLETE SPECIFICATION.
An Improved Method of Suspending the Bodies of Perambulators
or similar Vehicles.
I, CHARLES EDWARD COWTAN of 84 Aldenham Street, Somers Town,
London, N.W., Blacksmith 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 :-
This invention refers to children's carriages which have their bodies suspended
from the handle bars.
In my method the suspension is effected by interposing between the body of the
vehicle and the handle-bar, a short connecting rod or link-bar, at each end of which
is a pivot joint.
One of these pivot joints is constructed with the pivot-pin working in a slot, so as
to allow for the rise and fall of the body within a distance regulated by the length
of the slot. One end of this link bar is attached to the body, and the other to the
handle-bar or to a cross-bar upon the handle bar or between the two handle bars.
Tension or other springs of india-rubber or some suitable metal are fixed from
the handle-bars to the ends of the link bars in such a position as to support the body
at the proper height. The play of this spring affords the necessary protection
against jar when the carriage is in use.
I will now describe the invention with reference to the accompanying drawings
in which
Fig. 1 shows a side elevation of my improvements attached to a perambulator.

the two link-bars c, and spiral springs e.
Fig. 3 shows an enlarged plan view of my improvements.
Fig. 4 is an enlarged side elevation of the strap f, shewing the slot f¹, in same.
a, is the body of the perambulator.
b, is the handle bar. c, is the link-bar with forked ends d, d.
e, is the spiral spring with hooks e', e', at the two extremities. f, is the strap
which is screwed to the perambulator. 1, is a slot formed in the head of the
strap which allows the requisite play to the link-bar c. g, is a small pin
projecting at right angles from the link-bar c, on which the spring e, and strap f
are pivotted. ', 9', are nuts keeping the springs and straps in place. h, is a
connecting rod by which all vertical strain is equalised, and the perambulator kept
in a horizontal position. h', ', are small flanges keeping the forks d, in position.
-i, i, are nuts to secure the fork d.
By my suspension device side-play is prevented while any desired amount of
vertical elasticity is obtainable.
There is also less strain on the body and handle-bars than by the method now
in use.
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 :-
In a perambulator or similar vehicle with suspended body and two handle bars,
a horizontal bar rigidly connecting the handle bars the ends of which horizontal
bar are pivotally connected by link bars to two metal straps placed on the body of
the vehicle, the said straps having slotted eyes which engage with pivot pins in
ends of said link bars or the reverse; and two tension springs, connecting the outer
ends of the said link-bars or the body of the vehicle, to the said handle bars
at a level considerably above the said horizontal bar, as herein described and set
forth.
Dated this 14th day of July 1893.
