I WILLIAM FLETCHER of 30 & 31, Biggin Street Dover in the County of
Kent, Ironmonger do hereby declare the nature of my Invention for A NEW OR
IMPROVED, SAFETY LOOP OR CATCH FOR LOCKING OR HOLDING THE WHEELS OF
PERAMBULATORS, TRICYCLES AND OTHER LIGHT VEHICLES" to be as follows:-
My invention has for its object a ready and simple means of locking or holding
the wheels of perambulators, bicycles, tricycles and other. light vehicles whereby
such vehicles when unattended are safely secured and prevented from accidentally
leaving the position in which they have been placed.
My invention consists in the use of a safety loop or catch composed of two hooks
pivoted at their fulcrums and closing together at their hooked ends so as to form
a loop or eye. Each of these hooks is extended or formed on the other side of the
fulcrum with an arm or lever to one of which is secured a chain cord or other
attachment. Between the arms or levers is a spring which normally keeps them
apart and thereby closes the hooks. For ensuring a perfect closing of the latter
I rebate or bevel their hooked ends so that when closed they overlap and, thereby
prevent any accidental or opening thereof.
In applying my invention the chain or cord carrying the safety loop or catch
being suspended from or attached to any convenient part of the body or framing
of a perambulator or other vehicle the hooks are separated or opened by pressing
together their arms or levers and are then placed over the rim of one of the wheels
of the perambulator or other vehicle when the arms or levers being released the
action of the spring closes the books so as to form a loop or catch which surrounds
or embraces the rim and in conjunction with the chain or cord locks or prevents
the wheel.from turning and the vehicle thereby from moving.

By this invention in the case of perambulators all danger to children arising
from the carelessness of attendants is avoided and with other vehicles safety and
security from damage ensured.

page_text: I WILLIAM FLETCHER of 30 and 31 Biggin Street Dover in the County of Kent,
Ironmonger do hereby declare the nature of my said invention for "A NEW OR
IMPROVED SAFETY LOOP OR CATCH FOR LOCKING OR HOLDING THE WHEELS OF
PERAMBULATORS, TRICYCLES OR OTHER LIGHT VEHICLES" and in what manner
the same is to be performed to be particularly described and ascertained in
and by the following statement :—
My invention has for its object a ready and simple means of locking or, holding
the wheels of perambulators, bicycles, tricycles and other light vehicles whereby
such vehicles when unattended are safely secured, and prevented from accidentally
leaving the position in which they have been placed.
My invention is illustrated by figures 1, 2 and 3. on the accompanying drawing
like letters of reference indicating like parts in all the figures.
It consists in the use of a safety loop.or catch A composed of two hooks a. b
pivoted together at their common fulcrum c and closing together at their hooked
ends so as to form the loop or eye A-The hook a is.extended, or formed, on the
other side of the fulcrum c with an arm or lever d. to the end of which is attached
a chain (or cord) e-The hook b is also extended, or formed, on the other side of
the fulcrum c with an arm or lever f which is inclined outwards from the fulcrum c
at any desired angle to the arm or lever d. and between the arms or levers d
and f is a flat (or other) spring g which normally forces the arms or levers d and f
apart so as to keep the ends of the hooks a. and b closed, as shewn in figure 1.
For ensuring a perfect closure of the hooks a and b I rebate (or bevil) their ends
so that when closed together they overlap each other (see figure 3) and thereby
prevent any accidental separation or opening of the hooks a and b.
In applying my invention the chain (or cord) e carrying the safety loop or
catch A is suspended by a hook h, (screw clamp or otherwise). to any convenient
part of the body or framing of the perambulator or other vehicle to be secured.-
The hooks a and b are then separated or opened (as in dotted lines figure 1) by
pressing together the arms or levers d and f, and placed over the rim of one of the
wheels of the perambulator or other vehicle when the arms or levers d and f being
released the action of the spring g returns the arms d and f to their normal
position and closes the hooks a and b so that they embrace or surround the rim of
the wheel, which is thereby locked or prevented from turning and the perambulator
or other vehicle safely secured from the danger of leaving its position.
By my invention in the case of perambulators all danger to children arising
from the carelessness of their attendants is avoided and with other vehicles security
from damage ensured.

page_text: 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 construction and use of a safety loop or catch in combination with a chain
or cord substantially as and for the purpose hereinbefore described and illustrated
by the accompanying drawing.
