PROVISIONAL SPECIFICATION.
Improvements in Ball Cocks.
Alfred CliffORD, Claremont House, Hawley Road, near Dartford, Kent,
Plumber and Sanitary Engineer, do hereby declare the nature of this invention to
be as follows:-
To more clearly describe my invention this Specification is accompanied by a
sheet of drawings having three views.
Fig. 1. is the section of apparatus.
Fig. 2. is a perforated metal disc and
Fig. 3. is an external view of ball cock.
It will be seen in section Fig. 1, that the lever end of arm C is perforated so
that pin of B can work loosely in same. B is a metal casing fitted with india
rubber or other pliable packing so as to cover nozzle of supply pipe, to shut off
water when the ball is raised, and A is the perforated disc which is fitted in a
groove or collar in pipe and serves to stop any grit or dirt from getting under the.
rubber valve or entering cistern. D is an adjustable portion of outer casing which
can be removed when necessary to facilitate the arrangements of the different
parts. The valve B can be adjusted to end of lever arm C as shown or fixed on a
pin, or in other suitable manner.
