PROVISIONAL SPECIFICATION left by the said John Preston at the Office
of the Commissioners of Patents on the 18th May 1882.
JOHN PRESTON of No: 28 Armagh Road in the Parish of St Mary Stratford
le Bow in the County of Middlesex Perambulator Maker. "IMPROVEMENTS IN
PERAMBULATORS."
The back irons of the Perambulator instead of being rigidly fixed to the body of
the Perambulator are made in four separate pieces moving upon suitable joints in
such a way that the handle may be brought down to near the level of the back
wheels. When the Perambulator is in use these back irons are held firmly in
position by means of suitable stops moving back against springs.
The lower ends of the lower pieces of the back irons work upon pins fixed in
the back springs of the Perambulator-These back springs instead of being rigidly
fixed to the body are attached to the body by hinge joints upon which the springs
turn when the handle is lowered.
The springs of the front wheel are attached to a moveable piece or plate which
can be turned round on a pivot.-By this mode of attachment of the front wheel
it can be brought round upon the pivot so as to come under the body of the
Perambulator. When in use the the wheel is held in position by a suitable stop
and spring, the same stop and spring serving to hold the plate and wheel in
position when the wheel is brought under the body of the Perambulator.-This
movement of the front wheel under the body of the Perambulator may also be
brought about by attaching the springs to a hinged plate and turning the wheel
upon this hinge under the body. In this case also the wheel can be held in the
desired position by suitable stops and springs. In order to fold up the Perambulator
the front wheel is brought round under the body where it is held in position by
the stops The retaining stops of the back irons are then turned round in opposition
to their springs and the jointed back irons easily fall into the required position.
By these means the front wheel and back wheel are brought near together, the
front of the body rests upon the ground or floor and the body itself stands vertically
over the wheels in their new position.

the said John Preston in the Great Seal Patent Office on the 6th October
1882.
JOHN PRESTON of 28 Armagh Road in the Parish of St Mary Stratford
le Bow in the County of Middlesex Perambulator Maker. "IMPROVEMENTS IN
PERAMBULATORS."
This Invention relates to the construction of Perambulators in such a way that
while retaining the ordinary form of body they may be folded up into a small
compass when not in use. The improved Perambulator is represented in the
accompanying drawings.-Figures 1 and 2 show the perambulator when ready
for use.
Figures 3 and 4 are respectively side and back elevation when folded.
The following is the construction. The back irons of the perambulator instead of
being rigidly fixed to the body of the perambulator are made in separate pieces
D, D, E, E, Figure 2. The upper pieces D, D, move upon pins or bolts at N, N,
in the ribbed plates Z, Z, fixed to the body of the perambulator. The lower pieces
E, E, move upon pins or bolts at R, R. The upper portion of the back springs
HR figures 1 and 3 move upon hinge joints at H H.
The upper pieces D, D, of the back irons are jointed to the lower portions E, E,
figure 2 at K, K. and when the perambulator is ready for use the back irons are
held rigidly in position by the retaining stops X, X, figure 2-These retaining
stops X, X, work in holes in the ribbed plates Z₁ Z, and tend to keep the position
shown in figures 2 and 4 owing to the action of springs.
The springs of the front wheel are attached to a plate P figure 1 which plate can
be turned round upon the pivot V. By this mode of attachment of the front
wheel it can be brought round upon the pivot or pin V so as to come under the
body of the perambulator.
When in use the wheel C is held in position by the stop Q which stop can be
moved back against its spring the latter being indicated in figure by dotted
lines above the stop Q. When the wheel C is brought under the body of the
perambulator the saine stop Q is forced by its spring into a hole in the plate and
thus serves to retain the wheel in its new position. As shown in figure 1 the
plate P is inclined upwards towards the back of the perambulator.
The axle W W of the hind wheels B B is cranked as shown in figures 2 and 4
so as to allow the front wheel to clear it when the perambulator is folded. In
order to fuld the perambulator the stop is pressed up against its spring the
plate P can now turn upon the pivot V and the wheel can be brought round under
the body of the body of the perambulator. When the wheel is brought to the
required position the stop Q is forced by its spring into the hole in the plate and
the wheel is retained. The retaining stops X, X, of the back irons are then turned
round in opposition to their springs and these jointed back irons easily fall into
the required position by turning upon the respective joints. By means of a little
adjustment the front wheel and back wheels are brought near together and the
perambulator assumes the form shown in figure 3. A small roller may be attached
to the plate P in such a way that it meets the ground when the perambulator is in
the position shown in figure 3 and by this means the perambulator can be more
easily moved from place to place when folded.
Having now described the nature of the said Invention and in what manner
the same is to be performed I hereby declare that I claim the arrangement or
combination of parts forming an improved perambulator substantially as herein-
before described and shewn in the accompanying drawings; the essential features

page_text: in the said arrangement being (1) The jointing of the back-irons and mode of
attachment of the same to the body of the perambulator (2) The attachment of
the front wheel so that it may be brought under the body of the perambulator all
substantially as described and shown. In witness whereof I the said John Preston
have hereunto set my Hand and Seal this fifth day of October, One thousand
eight hundred and eighty two.
JOHN PRESTON. (L.S.)
