I EDWARD NUNAN of 166 Fleet Street, London, Gentleman do hereby declare
the nature of my invention for "IMPROVED MEANS AND APPLIANCES FOR SECURING
THE FALL DOWN HEADS OF CHILDRENS AND OTHER CARRIAGES IN ANY DESIRED
ま to be as
POSITION SAID APPLIANCES BEING APPLICABLE TO OTHER ARTICLES
follows:-
The object of my invention is improved means and appliances for securing the
Fall down heads of Children's and other carriages in any desired position said
appliances being applicable to other articles.
For the purpose of my invention I form a bar of quadrant or segmental shape
and secure one or both ends of it to a fixed body. On this bar I arrange a move-
able arın containing a cain or eccentric free to fall by gravitation when moved in
one direction, and pressed home into contact with a flat surface of the segmental
bar by a spring when moved in the reverse direction, the cam forming a key or
lock to fasten instantaneously and retain the arin in a fixed position.
The arm is attached, to say, the head of a carriage and this can be at any angle
or at the open or closed state. A straight pressure or draw on said eccentric or
lock allows the required movement to occur freely.

I EDWARD NUNAN of 166 Fleet Street, London Gentleman, 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 form an instantaneous fastening for movements
rotating on a centre.
The inode is as follows, to wit, I form a quadrant or segment fast at either or
both ends to say, the body, and a movable part to say the head of a carriage
requiring to be held fast at any part of said segment or made to move on said
segment or quadrant. When the quadrant is fastened at both ends I form an
aperture in a movable arm to embrace the quadrant or segment and in said
aperture 1 fit a cam or eccentric key or lock so that when the movable arm is
drawn in one direction along the quadrant the key or lock opens freely and
instantaneous and automatically fastens either by its own gravitation or by a
spring and when required to be free'd or opened for a movement in the reverse
direction a straight pressure or draw on said eccentric or lock allows the required
movement to occur freely.
My invention will be understood by the annexed sheet of drawings in which
I show at Figure 1 an example suitable for a carriage head this figure being an
elevation and Figure 2 a perspective view of same.
A, A, are two plates fastened on the body B of the carriage such as will be
understood by the perambulators or "bath chair" Figures 3 and 4 showing the
two positions the key or lock appliance occupies with the head in an open and
a closed position respectively. These two plates A, A, have a bar a portion of
which forms a segment of a circle or quadrant from the point D the other part
or front portion E being bent as shown. The bar C has a fiat surface F against
which the key G in the holder or arm H Figures 2 and 5 bears by its eccentricity
under the action of a spring I said key being socketed or pinned in the base J of
the movable arm H which is attached to the front hoop K of the carriage head L.
The key G on the edge opposite to the spring I has a lip M to enable the key G
to be pushed in and out of contact with the flat part F of the bar C which it
otherwise bites with sufficient grip to hold the carriage head L at any desired
angle.
The key G is fitted between two side cheeks of the holder H a part N of which
embraces the bar C and has a finger piece P projecting from it which enables the
holder and the key appliance and also the carriage head L to be lifted when a pull
is put upon said finger piece P, the spring I being pressed in at the same time; this
is etfected by simply straddling two fingers across the bar C and pulling the holder,
which pull releases the grip of the key G and allows the holder H to travel on
said bar O.

page_text: When the carriage head L has to be lowered two fingers are straddled across the
bar C on the opposite side of the appliance and a pressure is exerted against
the finger piece P and against the lip M of the key G which is pushed in and its
grip released from the bar C. So soon as the fingers are released the key G is
forced back under the action of its spring I and fixes the head of the carriage
at that spot.
The examples given are only to illustrate my invention, the locking appliance
being applicable to straight or curved bars in various kinds of mechanism in which
a positive fixture of one piece of mechanism is desired at various points of another
portion of the mechanism.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The means and appliances herein before described for securing the fall down heads
of Childrens and other carriages or other articles at any desired position substan-
tially as shown in the annexed drawings.
