COMPLETE SPECIFICATION.
An Improved Adjustable Joint for Hoods or Heads of Carriages.
I, THOMAS HENRY BROOKE HITCHING of 198 Oxford Street and 21 Ludgate
Hill, London, Perambulator Manufacturer 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 refers to the jointed stay rods employed for extending the hoods
of perambulators, bath chairs and carriages. It consists of the usual pivot or
knuckle joint composed of two discs or their equivalents and a knuckle working
between saine connected by a central pin or rivet, said joint being furnished with
the usual projecting stop which prevents it from opening beyond the straight or
extended position.
These joints are sometimes furnished with a quadrant and sleeve fitted with a
set screw, so that they can be fixed in any intermediate position.
can be
My invention supplies an improvement by means of which the arm
adjusted to any required angle without the liability to frequent breakage which
pertains to the quadrant arrangement.
On one half of the joint I form in the solid metal a semi-circular or crescent
shaped extension plate, fitted with recessed holes to receive the point of a set screw
which is mounted in a projecting boss on the other half of the joint. This arrange
ment I find far stronger and more reliable than the quadrant while it is more
compact and neater in appearance.
I will now describe the invention with reference to the accompanying drawings
in which,
Fig. 1 shows a plan view of my improved joint for adjusting perambulator or
other carriage hoods.
Fig. 2 shows a plan of the reverse side of same.
Fig. 3 shows an end view of same in the partly open position with the locking
screw and boss shown in section.
a, is one half or part of the joint and to which is attached the extension
plate c.
a', is a plate or washer attached to a, in which the pin or axis of the joint
is rivetted at one side.
b, is the other half of the joint formed with a boss d, which holds the set
screw e.
c, is the extension plate provided with holes c¹, on its face. It is formed
solid with the half a, of the joint.
d, is a small projecting boss cast on the half b of the joint and tapped to receive
the locking screw e.
e, is a locking screw working in the boss d, which engages at its lower end with
the holes c¹, in the extension plate c.
This screw is provided with a stop for preventing it dropping out when
unscrewed.
h, is a milled head to the screw e.
k, is the usual stop formed on the half joint a, the boss d forming the stop
on the other half joint b, permitting the rods to be opened out straight but not
farther.
I, I, are the rods which are operated by means of the joint a, b.

page_text: 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 :-
In a joint for an extension stay for hoods or heads of carriages and like purposes
the projecting plate e, and boss d, with its locking screw e, as herein described and
set forth.
