"AN IMPROVEMENT OR IMPROVEMENTS IN THE JOINTS OF PERAMBULATOR AND
CARRIAGE HOODS
"
The joints of perambulator and carriage hoods consist of two rods jointed
together at their inner ends the outer end of one rod being jointed to the
perambulator or carriage hood and the outer end of the other rod being jointed to
the body of the perambulator or carriage. By means of the middle joint the two
rods are brought into the same line on opening or expanding the hood and fold
upon one another on closing the hood.
The middle joint as ordinarily made consists of a pair of side knuckles on one
rod between which a single knuckle on the other rod is fitted the three knuckles
urning on a riveted axis passed through them. The stops for limiting the opening
of the two rods are situated at the edges of the knuckles.
According to my invention I construct the middle joint of the two jointed rods
in the following manner.
Instead of forming the joint of three knuckles engaged together as described I
make the said joint of two strong discs placed face to face and riveted together by
a joint pin passed through them. Into the edge of one disc the inner end of one
rod is screwed and into the edge of the other disc the inner end of the other rod
is screwed. The rods thus jointed together are brought nearly into the same line
on opening or expanding the hood and fold upon one another on closing the hood.
In order to limit the opening out of the rods I construct the stop in the following.

crossing the said groove is a bar or stop and on the inner face of the other disc I
make a stop pin having a size and shape and position proper to work in the groove
in the first named disc. When the rods are turned upon their joint for expanding
the hood the stop pin works in the groove and when the rods have been opened
out to their full extent their further motion is arrested by the said stop pin on one
disc coming against the cross bar or stop in the groove in the other disc.

"AN IMPROVEMENT OR IMPROVEMENTS IN THE JOINTS OF PERAMBULATOR AND
CARRIAGE HOODS
"
The joints of perambulator and carriage hoods consist of two rods jointed
together at their inner ends, the outer end of one rod being jointed to the
perambulator or carriage hood and the outer end of the other rod being jointed to
the body of the perambulator or carriage. By means of the middle joint the two
rods are brought into the same line on opening or expanding the hood and fold
upon one another on closing the hood.
The middle joint as ordinarily made consists of a pair of side knuckles on one
rod between which a single knuckle on the other rod is fitted, the three knuckles
turning on a riveted axis passed through them. The stops for limiting the opening
of the two rods are situated at the edges of the knuckles.
According to my invention I construct the middle joint of the two jointed rods
in the following manner.
Instead of forming the joint of three knuckles engaged together as described I
make the said joint of two strong discs placed face to face and riveted together by
a joint pin passed through them. Into the edge of one disc the inner end of one
rod is screwed and into the edge of the other disc the inner end of the other rod
is screwed. The rods thus jointed, together are brought nearly into the same line
on opening or expanding the hood and fold upon one another on closing the hood.
In order to limit the opening out of the rods I construct the stop in the following
manner. In the inner face of one of the discs I make a deep circular groove and
crossing the said groove is a bar or stop, and on the inner face of the other disc. I
make a stop pin having a size and shape and position proper to work in the groove
in the first named disc. When the rods are turned upon their joint for expanding
the hood, the stop pin works in the groove and when the rods have been opened
out to their full extent their further motion is arrested by the said stop pin on one
disc coming against the cross bar or stop in the groove in the other disc.
I will now proceed to described with reference to the accompanying Drawing the
manner in which my invention is to be performed.
Figure 1 represents the hood of a perambulator to which a joint constructed
according to my invention is applied, the two jointed rods being represented
opened out or brought nearly into the same line and the hood in its expanded
state.
Figure 2 represents in front elevation and side elevation the said jointed rods
drawn to a larger scale detached from the hood and Figure 3 represents the said
jointed rods folded for closing the hood.
Figure 4 represents in front elevation and side elevation the middle joint of the
said jointed rods drawn to a larger scale than Figures 2 and 3; and Figure 5
represents one portion of the middle joint separately and Figure 6 represents the
other portion of the middle joint separately.
The same letters of reference indicate the same parts in the several Figures of
the drawing.

the outer end of the
outer end of the rod b.
The middle joint by

page_text: which the two rods a, b are jointed together consists of two strong discs f, g placed
face to face and turning on the joint pin h which is passed through them and
riveted as represented. In the edge of the disc f the rod a is screwed or otherwise
fixed and into the edge of the disc g the other rod b is screwed or otherwise fixed.
The rods a, b thus jointed together when opened out for expanding the perambulator
hood are brought nearly into the same line as seen in Figure 2 and when the hood
is closed they fold upon one another as seen in Figure 3.
•
The stop for limiting the opening out of the jointed rods a, b is constructed as
follows:-
i and
In the inner face of the disc g. of the middle joint is a circular groove
crossing the said groove is a bar or stop k and on the inner face of the other, disc f
of the middle joint is a stop pin 7 which works in the groove in the disc g.
When the two rods a, b are turned upon their joint, pin h for expanding the
hood, the stop pin on the disc fworks in the groove i 'in the disc g and when the
two rods have been opened to their full extent as illustrated in Figures 1, 2 and 4
so as to bring them nearly into the same line, their further motion is arrested by
the said stop pin' coming against the cross bar or stop k in the groove in the
disc g as indicated in 'dotted lines in Figure 4.

I apply my invention to the joints of carriage hoods substantially in the manner
hereinbefore described and illustrated with respect to the joint of a perambulator
hood.

By my invention a very strong middle joint is made. The making of the said
joint is less costly than the ordinary joint and in consequence of the absence of
external stops the pinching of the hand between the stops which often occurs in
the use of the ordinary joint is prevented.
Having now described the nature of my invention and the manner in which
the same is to be performed I wish it to be understood that I claim as my
invention The improvement or improvements in the joints of perambulator and
carriage hoods herein before described and illustrated in the accompanying
Drawing; that is to say, constructing the middle joint by which the two rods
constituting the essential parts of the hood joint are jointed together, of two discs
placed face to face and turning on a joint pin the opening out of the two rods
being limited by means of a stop pin on one disc coming against a cross bar or
stop in a circular groove in the other disc, in which circular groove the stop pin
works substantially as and for the purposes herein before described and illustrated:
In witness whereof I the said James Collett have hereunto set my hand and
seal this Twenty second-day of August in the year of our Lord one thousand
