page_text: I THOMAS MADDOX of 13 Northcote Road Wandsworth in the county of Surrey
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide perambulators with springs that shall be
very easy and yielding and not at all liable to break or get out of order while if
renewal or repair is required it can easily be accomplished.
To carry out this object say in a four wheeled perambulator the axles of the wheels
are rigidly connected together by preferably two bars or rods and under the body of
the perambulator are fitted any of the usual or ordinary appliances or contrivances to
raise the same to the desired height off the ground. I preferably use flat springs or
bars the central parts whereof are secured on each side under the body while the ends
thereof are turned down somewhat in the shape of inverted Cs. Between the ends of
these inverted Cs or in similar positions under the other appliances or contrivances
and the axles of the wheels preferably over the two bars or rods that connect the same
are fitted four springs preferably metallic coiled or spiral springs arranged vertically
by which the body of the perambulator is entirely carried and which are obviously
very easy and yielding and can when required separately be renewed or repaired.
In a three wheeled perambulator these vertical springs, would be fitted in the same
manner but over the front wheel there may be either one or two of these vertical
springs according as the bars or rods below are made into a fork or otherwise for this
front wheel and according as the appliances or contrivances under the body of the
perambulator are arranged.

page_text: I THOMAS MADDOX of 13 Northcote Road Wandsworth in the county of Surrey
Engineer 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 my invention is to provide perambulators with springs that shall be
very easy and yielding and not at all liable to break or get out of order while if
renewal or repair is at any time required it can easily quickly and cheaply be
accomplished.
In the accompanying drawing I have shewn an ordinary four wheeled perambulator
as fitted with this my invention.
Figure 1 is a side elevation of the perambulator and Figure 2 is a side elevation
partly in section and on an enlarged scale of one form and style of the apparatus on
which the body of the perambulator is mounted shewing my springs.
The axles A on which the wheels of the perambulator are mounted are rigidly
connected together by preferably two bars or rods B formed of the desired and
suitable shape and under the body of the perambulator are fitted any of the usual or
ordinary appliances or contrivances to raise the same to the desired height off the
ground. As is shewn in the drawing I preferably use flat springs or bars C the
central parts whereof are secured under the body of the perambulator one being on
each side while the ends thereof are turned down semicircularly or thereabouts
whereby an apparatus somewhat similar to four inverted Cee springs is produced.
Between the ends of these inverted Cee springs C or thereabouts or in similar
positions under the other appliances or contrivances and the axles A of the wheels
and preferably if so fitted over the two bars or rods B that connect the axles A are
fitted four springs D preferably as shewn metallic coiled or spiral springs arranged
vertically by which springs D the body of the perambulator is entirely carried and
which springs Dare and obviously must be very easy and yielding and can when
required separately be renewed or repaired. Instead of the metallic coiled or spiral
springs shewn I could also use pieces of india rubber or other compressible material
arranged vertically in a similar manner. To save the springs D from any twisting or
lateral strain when the perambulator is being pushed along as is customary by an
handle attached to the body thereof I can very conveniently fit the bolts E which pass
through the axles A and preferably also through the bars or rods B or may surround
the same and pass up the centres of the springs D or it may be outside the same to
the ends of the inverted Cee springs C or to the other appliances or contrivances
under the body of the perambulator. The bolts E are firmly and rigidly attached to
the one part and can travel freely through or round the other part when and as the
springs give and play and I preferably as shewn attach the bolts E to the axles A and
the bars or rods B whereby they are rendered the more rigid allowing the other ends
thereof where they are fitted with caps or nuts to travel through the flat springs or
bars C.

page_text: In a three wheeled perambulator these vertical springs would be fitted in the same
manner but over or near the single wheel there may be either one or two of these
vertical springs according as the bars or rods below are made into a fork or otherwise
for this single wheel and according as the appliances or contrivances under the body
of the perambulator are arranged.
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
