page_text: I WILLIAM HENRY DUNKLEY of Jamaica Row Birmingham in the County of
Warwick Perambulator and Carriage Manufacturer do hereby declare the nature of
this Invention to be as follows:-
My invention consists of the improvements herein after described in suspending
the body of the perambulator and also of the improvements herein after described
in supporting and adjusting the position of the hood or canopy of the perambulator.
I support on brackets secured to the axles of the perambulator two parallel nearly
semi-circular springs or bars having scroll ends the said springs or bars extending
from one end to the opposite end of the body of the perambulator. To the scroll
ends of the said springs or bars cross handles are fixed by which the perambulator is
propelled. The ends of each propelling handle extend beyond the scroll ends of the
springs or bars and to each of the said extended ends of the propelling handles a
strong coiled suspending spring is connected the opposite end of each coiled spring
being connected to a plate fixed to the side of the body of the perambulator. The
parts for supporting and suspending the body of the perambulator thus consist of two
nearly semi circular springs or bars supporting the cross propelling handles and two
pairs of strong coiled springs one pair being fixed to each of the cross handles and to
the body of the perambulator for suspending the said body. By means of the said
strong coiled springs which have a great range of elasticity the body of the peram-
bulator is so suspended that it has great freedom of motion. I support the hood or
canopy over the body of the perambulator so that it can be adjusted towards either
end or either side of the body and fixed in its adjusted position by the following con-
struction and arrangement of parts. Crossing the top of the middle of the perambulator
body is a bar to which the supporting rod of the hood or canopy is jointed by a
double joint one joint above the other the upper joint permitting the canopy rod to
move towards either side of the perambulator body and the lower joint permitting the
canopy rod to move towards either end of the said body. The jointed parts of the
canopy rod are thus made capable of moving at right angles to one another. Each
joint consists of two discs serrated on their opposed faces one. of the serrated discs

The lower joint which permits of the end motion of the canopy,ród, consists of a short
vertical arm fixed to the cross-bar on the perambulator.body. This fixed arm carries
the fixed serrated disc to which the loose serrated disc is clamped by a screw. The
loose serrated disc of the lower joint also carries a short arm on the upper end of
which the fixed serrated disc of the upper joint is made. The loose serrated disc of
the upper joint carries the canopy rod which is connected to the middle of the hood
or canopy. The canopy is capable of a slight angular motion on the top of its
supporting rod.

I WILLIAM HENRY DUNKLEY of Jamaica Row Birmingham in the County of
Warwick Perambulator and Carriage Manufacturer do hereby declare the nature of
my invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention consists of the improvements hereinafter described in suspending the
body of the perambulator and also of the improvements herein after described in
supporting and adjusting the position of the hood or canopy of the perambulator.
I support on brackets secured to the axles of the perambulator two parallel nearly
semi-circular springs or bars having scroll ends, the said springs or bars extending
from one end to the opposite end of the body of the perambulator. To the scroll
ends of the said springs or bars cross handles are fixed by which the perambulator is
propelled. The ends of each propelling handle extend beyond the scroll ends of the
springs or bars and to each of the said extended ends of the propelling handles a
strong coiled suspending spring is connected, the opposite end of each coiled spring.
being connected to a plate fixed to the side of the body of the perambulator. The
parts for supporting and suspending the body of the perambulator thus consist of two
nearly semi-circular springs or bars supporting the cross propelling handles and two
pairs of strong coiled springs, one pair being fixed to each of the cross handles and to
the body of the perambulator for suspending the said body. By means of the
said strong coiled springs which have a great range of elasticity the body of the
perambulator is so suspended that it has great freedom of motion.
'I support the hood or canopy over the body of the perambulator so that it can be
adjusted towards either end or either side of the body and fixed in its adjusted position
by the following construction and arrangement of parts. Crossing the top of the
middle of the perambulator body is a bar to which the supporting rod of the hood or
canopy is jointed by a double joint one joint above the other, the upper joint per-
mitting the canopy rod to move towards either side of the perambulator body and the
lower joint permitting the canopy rod to move towards either end of the said body.
The jointed parts of the canopy rod are thus made capable of moving at right angles
to one another.

Each joint consists of two discs serrated on their opposed faces, one of the serrated
discs being loose and drawn and clamped to the fixed serrated disc by a clamping
screw. The lower joint which permits of the end motion of the canopy rod consists
of a short vertical arm fixed to the cross bar on the perambulator body. This fixed arm..
carries the fixed serrated disc to which the loose serrated disc is clamped by a screw.
The loose serrated diso of the lower joint also carries a short arm on the upper end of
which the fixed serrated disc of the upper joint is made. The loose serrated disc of the
upper joint carries the canopy rod which is connected to the middle of the hood or
canopy. The canopy is capable of a slight angular motion on the top of its
supporting rod.

page_text: I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in side elevation; Figure 2 in plan and Figure 3 in end
elevation a perambulator the body of which is suspended and the hood or canopy
supported and adjusted according to my invention; Figures 4 and 5 represent
elevations taken in planes at right angles to one another (partly in section) of the
supporting and adjustable rod of the bood or canopy drawn to a larger scale.
The same letters of reference indicate the same parts in the several Figures of the
drawings.
a is the body of the perambulator and b, b are the two parallel nearly semi-circular
springs or bars supported on the brackets d, d fixed to the axles c, c of the perambulator
wheels, the said springs or bars b, b extending from one end to the opposite end of the
body of the perambulator as seen in Figure 1. The ends of the semi-circular
springs b, b are made into scrolls at 63, 62 and to the scroll ends of the semi-circular
springs or bars cross handles e, e are fixed by which the perambulator is propelled,
the ends of the propelling handles ee extending beyond the said semi-circular springs
or bars as best seen in Figures 2 and 3; ff are the strong coiled springs by which
the body of the perambulator is suspended to the semi-circular springs or bars bb
through the propelling handles e e. It will be seen by an examination of the drawings
that to each of the extended ends of the propelling handles e, e a coiled suspending
spring is connected the opposite or inner end of each coiled spring being hooked
to a plate at g fixed to the side of the body of the perambulator. Thus, the parts
for supporting and suspending the body of the perambulator consist of two nearly
semi-circular springs or bars 6, 6 supporting the cross propelling handles ee and the
two pairs of strong coiled springs f, f, one pair being fixed to each of the cross
handles e and to the body of the perambulator the said coiled suspending springs
having a great range of elasticity so that the body suspended by them has great
freedom of motion.
Although I prefer to combine the suspending coiled springs with the semi-circular
springs or bars carrying the cross propelling handles as described and represented
yet the propelling handles to which the outer ends of the supporting coiled springs
are secured may be supported from the axles of the perambulator in other equivalent
ways.
I will now describe the mechanism for supporting and adjusting the hood or
canopy of the perambulator.
½ is the hood or canopy having by preference a nearly oblong figure in plan (see
Figure 2) and i, k is the double jointed or compound supporting rod of the canopy,
i being the upper jointed part to which the canopy is secured and k the lower jointed
part which is jointed to the fixed short upright on the middle of the cross bar m,
the ends of which are fitted into sockets at opposite sides of the body a of the
perambulator and fixed by set screws p, p. The two parts i, k of the jointed canopy
rod are so jointed together that the said parts are capable of moving at right angles
to one another for the purposes hereinafter described.
The joint of the lower part of the canopy rod consists of the two serrated
discs k², the disc 2 being formed on the short fixed upright and the other disc
being formed on the lower part of the rod k. The fixed disc 12 carries the joint
pin m on which the clamping screw p works. By driving home or relaxing the
clamping screw p the loose disc k on the rod k can be clamped to the other disc (2
or be released therefrom and permitted to turn upon the joint pin n. The parts of
the joint of the upper rod i are made in a similar way. That is, the upper part of the
lower rod k carries the serrated disc k³ and the upper part of the canopy rod
carries the serrated disc 2 and the fixed joint pin q at right angles to the joint
pin n the disc being clamped to or released from the disc k³ by the clamping
screw r.
By unclamping the upper jointed part from the lower jointed part k of the
canopy rod the same part i can be turned or inclined towards one or other side
of the perambulator body as indicated in dotted lines in Figure 3 and fixed in that

page_text: position by reclamping the joint and by unclamping the lower joint part of the
canopy rod the said part k together with the part i can be turned or inclined
towards either end of the perambulator body as indicated in dotted lines in Figure 1
and fixed in that position by reclamping the joint. The hood or canopy can thereby
be made to take at either side or at either end of the perambulator body the
inclined positions indicated with respect to one side and one end shown in the
Drawings.
Hoods or canopies of various constructions and shapes may be carried by canopy
rods constructed according to my invention. I prefer however to construct the
frame of the canopy or hood so that about one half of it can be closed and turned
back upon the other half as indicated at h³ ³ in Figure 2. For this purpose one
half of the canopy is divided at 2 Figure 2 and the ribs or supporting frame of that
half of the canopy are made capable of swivelling or turning horizontally on the
middle plates to which the several ribs or frame parts of the canopy are jointed.
Having now particularly described and ascertained the nature of my_inven-
tion and the manner in which the same is to be performed I declare that I claim
as my invention of "Improvements in perambulators"
:-
First Suspending the bodies of perambulators from the propelling handles of the
perambulator by means of strong coiled springs the said propelling handles being
supported preferably by semi-circular springs or bars fixed to the axles of the
perambulator substantially as herein before described and illustrated in the accom-
panying Drawings.
Secondly The double jointed or compound hood or canopy rods of perambulators
hereinbefore described and illustrated in the accompanying drawings, whereby the
hood or canopy can be fixed symmetrically over the body of the perambulator or be
turned or inclined towards either side or either end of the said body, the parts of
the said double jointed or compound hood or canopy rod being constructed and used
substantially as described and illustrated.
