Improvements in Perambulator Fittings.
We GEORGE MOORE Junior, and JOHN CLEMENT MOORE, both of Priory
Works, Aston, near Birmingham, Brassfounders do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in what are known as folding joints or
fittings for perambulators, and consists primarily in strengthening the ends of the
rods or tubes used in such fittings by means of external caps cast or stamped,
preferably the latter; also in providing an improved stamped joint plate; also the
method of securing the said caps carrying the joint pins, upon the rods or tubes;
and the method of pinning the whole together, all as hereinafter described.
Usually these fittings are made of two rods or tubes screwthreaded at each of
their ends and connected to each other by means of what is known as a cast rule
joint, the outer ends of such joint being screwthreaded to receive the one end of
each of the rods. Each of the other ends of these rods or tubes are similarly connected
to a cast end fitting having securing screw holes by which it is secured to the
perambulator or to the hood as the case may be.
In these cases much trouble is experienced by reason of their frequent breaking
at the junction of the rods with the joints and the end fitting; also the production
of such joints is expensive and troublesome.
In this our invention however, we produce a. very much stronger article of an
improved shape, and very much less costly.
and
We cut the rods or tubes to the required length. We now make a cap to fit
externally on each end of these tubes or rods. These caps may be of cast metal,
but we prefer to stamp or draw them from a sheet metal blank in the ordinary
manner that such articles are made, that is, of a tubular form, having their one
end closed. Its other (open) end is trimmed if necessary, and then forced on to
the end of this rod or tube aforesaid, its internal diameter being arranged so as to
fit tightly thereon. A central end wise slot is now cut in one end of each of these
capped rods for a given distance down. This slot thus cuts through the cap
through the tube. A metal joint plate is now stamped or cut out of suitable shape,
whose thickness is equal to the slot hole in the ends of the rods being in line with
and near to each other. A pin hole is now drilled through each of the caps, rods
and plate at right angles to the slot, when a pin is inserted and rivetted therein,
just forming the two joints upon the one plate. The said plate on the one side is
shaped concentrically from cach of the centres of the joint pins, so as to enable
the rods being part rotated on such pins, towards or parallel to each other, the
one way and back to a straight line with each other the other way, its shape being
such as to limit the latter movement thus far only.
A pin hole is similarly drilled at the other ends of the rods or tubes, through
which passes a joint pin which is rivetted or otherwise secured to a bracket, having
screw holes, by which it may be secured to the hood at the one end, (of the
complete fitting), and to the perambulator at the other end.

Improvements in Perambulator Fittings.
We GEORGE MOORE Junior, and JOHN CLEMENT MOORE, both of Priory
Works, Aston, near Birmingham, Brassfounders, 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 relates to improvements in what are known as folding joints or
fittings for perambulators, and consists as hereinafter described.
Usually these fittings are made of two rods or tubes screwthreaded at each of
their ends and connected to each other by means of what is known as a cast rule
joint, the outer ends of such joint being screwthreaded to receive the one end of
each of the rods. Each of the other ends of these rods or tubes are similarly
connected to a cast end fitting having securing screw holes by which it is secured
to the perambulator or to the hood as the case may be.
In these cases much trouble is experienced by reason of their frequent breaking
at the junction of the rods with the joints and the end fitting; also the production
of such joints is expensive and troublesome.
In this our invention however we produce a very much stronger article of an
improved shape, and very much less costly.
In order to more particularly explain this our invention we have appended
hereunto an illustrative sheet of drawings upon which are figures and numbers of
reference, similar numbers referring throughout the several views to the same
thing or part.
Fig. 1, is a general side view of the fitting complete.
Fig. 2, is a plan view of the fitting.
Figs. 3, 4, 5 & 6, are detached detail views of the parts forming this our
improved fitting.
Fig. 7, is a part sectional view showing the arrangement of construction.
We cut two rods or tubes 8, to the required length. We now make caps 9 & 10,
to fit externally on each end of these tubes or rods. These caps may be of cast
metal, but we prefer to stamp and draw them from a sheet metal blank in the
ordinary manner, that such articles are made, that is, of a tubular form, having
their one ends 11 & 12 closed. Their other (open) ends are trimmed if necessary
and then each cap is forced on to the end of the rod or tube 8, their internal
diameter being arranged so as to fit tightly thereon. A central endwise slot 13, is
now cut in the one end of each of these capped rods for a given distance down.
This slot thus cuts through the cap 9, and also through the tube 8. A metal joint
plate 14, is now stamped or cut out of suitable shape, whose thickness is equal to
the width of the slot hole 13, in the ends of the rods or tubes and caps. Pin
holes 15, are now drilled through each of the caps, rods and plate, at right angles
to the slot,, when a pin 16, is inserted and rivetted therein, thus forming the two
joints upon the one plate, as seen in Figs. 1, 2 & 7. The said plate 14, on the
one side at 17, 17, is shaped concentrically or thereabouts from each of the centres
of the joint pins, so as to enable the rods 8, 8, being part rotated on such. pius,
towards or parallel to each other the one way, and back to a straight line with
cach other the other way, its shape being such as to limit the latter movement
thus far only. A pin hole is similarly drilled at the other ends of the rods or
tubes, and through the caps 10, 10, through which is passed the joint pin 18,
which is rivetted or otherwise secured to a bracket 19, having screwholes 20, 20,
by which it may be secured to the hood at the one end, (of the complete fitting)
and to the perambulator at the other end.
Thus by these means we strengthen the ends and joints of such fittings, retaining
the full strength of the tubes at their junction with the caps, and at the same time
presenting a more uniform appearance.

page_text: Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
1. In perambulator hood fittings the combination with the rod 8, of an end cap
or caps by which the ends of such rods are jointed to their respective fittings
substantially as shown and described.
2. The general combination and arrangement with the rods 8, 8, and
brackets 19, 19, of the caps 9 & 10, and joint plate 14, constructed and operating
as shown and described.
