Improvement in or relating to Ball Valves.
JAMES THOMAS GARRATT of 33 Leipsic Road, Camberwell in the County
of Surrey, Brass Founder, do hereby declare the nature of this invention to be as
follows:-
:-
The object of this invention is to construct ball valves so that they shall not be
liable to leak especially when employed for very high pressures as is now commonly
the case.
According to this invention I pass a short lever or arm through the slot in stem
of valve the fulcrum of said lever being at back of valve casting and the other end
of said lever extending through a slot in opposite side of the valve casting the
fulcrum of the lever that carries the ball being over the aforesaid short lever so
that as the ball rises and falls the lever thereof actuates the valve by pressing on
the tail end of the said short lever.
Dated this 16th day of March 1893.

Improvement in or relating to Ball Valves.
I JAMES THOMAS GARRATT of 33 Leipsic Road, Camberwell in the County of
Surrey, Brass Founder, 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 this invention is to construct ball valves so that they shall not be
liable to leak especially when employed for very high pressures as is now commonly
the case.
According to this invention I pass a short lever or arm through the slot in stem
of valve the fulcrum of said lever being at back of valve casting and the other end
of said lever extending through a slot in opposite side of the valve casting the
fulcrum of the lever that carries the ball being under the aforesaid short lever so
that as the ball rises and falls the lever thereof actuates the valve by pressing on
the tail end of the said short lever.
And in order that my said invention may be fully understood I will describe the
same with reference to the accompanying sheet of drawings which shews elevation
of ball cock constructed according to my said invention.
a shews the cock, b valve, e short arm or lever passing through a slot i in stem
of valve b. d lever to which the ball e is connected this lever is pivotted at f, to
arm k cast on cock a the tail end g, coming under the end of lever c, this lever is
pivotted at h.
It will easily be seen on reference to the drawing that upon the ball e floating the
tail g will act against the end of lever c and thus close the valve b.
By this invention the valve will be more securely closed than heretofore as the
leverage will be far greater.
