page_text: We, SEPTIMUS ALEXANDER PARKES Gentleman, of Holbrook, Park Road,
Surbiton, Surrey, and ORLANDO HENRY WAGNER Gentleman, of 9, Winfrith Road,
Earlsfield do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in connection with ball cocks, and has
for its object to provide a simple construction in the Ball Cock commonly in use,
which will gradually shut off the water pressure from the plunger, so that when
the supply is cut off the plunger has been entirely relieved.
In carrying out our invention the plunger is hollow for the greater part of its
length and is formed with two sets of perforations or holes, one close to the upper
end and the other at the lower end. The casing is provided with a recess in its
upper side into which the hollow end of the plunger extends. When the cistern
is filled with water and the ball arm which actuates the plunger is raised, the
perforations are contained respectively within the recess and the passage of the
casing, the water being prevented from passing through the plunger. A small
rubber band is placed around the shoulder of the plunger, and the casing is pro-
vided with a small ring or lip lengthening the passage through which the plunger
passes.
When the plunger is fully raised the rubber ring bears against the lip and forms
a tight joint.
The plunger from the shoulder downwards may be solid, and below the shoulder
there is a slot through which passes the ball arm which actuates the plunger.
Owing to the water passages being in the side of the plunger they are gradually
closed as the latter is raised, so that the water supply is slowly stopped, and the
pressure on the plunger slowly taken off. The rubber band serves to prevent any
water trickling through, but the flow of water is stopped by the plunger itself,
all the apertures being concealed in the recess and passage. When the cock is
open the water passes into the upper apertures down inside the plunger and out
of the lower apertures of the plunger, and impinges against the sides of the casing
which is formed with a recess at its lower side to receive the lower end of the
plunger. The water thus falls between the plunger and the casing into the
cistern.

page_text: We, SEPTIMUS ALEXANDER PARKES Gentleman, of Holbrook, Park Road,
Surbiton, Surrey, and ORLANDO HENRY WAGNER Gentleman of 9, Winfrith Road,
Earlsfield, 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 relates to improvements in connection with ball cocks, and has
for its object to provide a simple .construction in the ball cock commonly in use,
which will gradually shut off the water pressure from the plunger, so that when
the supply is cut off the plunger has been entirely relieved.
In carrying out our invention the plunger is hollow for the greater part of its
length and is formed with two sets of nerforations or holes, one close to the upper
end and the other at the lower end. The casing is provided with a recess in its
upper side into which the hollow end of the plunger extends. When the cistern
is filled with water and the ball arm which actuates the plunger is raised, the
perforations are contained respectively within the recess and the passage of the
casing, the water being prevented from passing through the plunger. A small
rubber band or washer is placed around the shoulder of the plunger, and the casing
is provided with a small ring or lip lengthening the passage through which the
plunger passes. When the plunger is fully raised the rubber ring bears against
the lip and forms a tight joint.
The plunger from the shoulder downwards may be solid, and below the shoulder
there is a slot through which the ball arm passes which actuates the plunger.
Owing to the water passages being in the side of the plunger they are gradually
closed as the latter is raised, so that the water supply is slowly stopped, and the
pressure on the plunger slowly taken off. The rubber band serves to prevent any
water trickling through, but the flow of water is stopped by the plunger itself,
all the apertures being enclosed in and by the recess and passage. When the cock
is open the water passes into the upper apertures down inside the plunger and
impinges against the sides of the casing which is formed with a recess at its lower
side to receive the lower end of the plunger. The water thus falls between the
plunger and the easing into the cistern.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawings, in which Fig. 1 is a cross section of our improved
valve, and Fig. 2 is a detail view of the plunger showing it in cross section.
A is the casing formed with the central passage a and the vertical passage a¹
which extends into the upper side of the casing forming a recess. Within the
passage a¹ the plunger B is placed having the shoulder b close to its lower end.
The main part of this plunger is hollow and is provided with the upper and lower
water ways or holes 61 and 6. These holes are at the sides.
The passage a¹ is continued by the ring or extension a projecting a short dis-
tance below the body of the casing. On the shoulder 6 the rubber ring C or washer
is placed, and to keep this in proper position the small screw cap c is employed
screwed or fitted over the shoulder and keeping the ring in place by a flange.
When the plunger is fully raised the rubber ring will project against the edge
of the lin a forming a thoroughly water-tight joint. To the lower end of the
plunger the ball arm D is fitted passing through a slot in the plunger. The casing
extends at a³ so as to form a chamber or recess within which the lower part of
the plunger is contained, space being allowed for the water to pass away.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.-
(1) In an improved ballcock, the combination with a casing having a vertical
passage, which passage extends into the upper side of the casing forming a recess,
of a hollow plunger placed within the said passage and two sets of openings in the
side of the said plunger, one within the casing and the other adapted to slide and
close within it or to open beneath it substantially as described and for the purposes
specified.
(2) In an improved ballcock, the combination with a casing having a vertical
passage, which passage extends into the upper side of the casing forming a recess,
of a hollow plunger within the said passage, two sets of openings, one at the upper
and the other at the lower end of the said plunger, a shoulder beneath he lower
opening, and a band or washer of rubber or other suitable material on the said
shoulder forming a joint when the cock is closed, substantially as described and
for the purposes specified.
(3) In an improved ballcock the combination with a casing having a vertical
passage, and a tubular extension at the lower end of the said passage, of a hollow
plunger within the passage, two sets of openings in the side of the plunger a
shoulder at the lower end, and a rubber band or washer on the said shoulder
bearing against the tubular extension when the cock is closed substantially as
described and for the purposes specified.
(4) The improved ballcock having a casing provided with a vertical passage,
a tubular extension to the said passage, and an outer chamber, a hollow plunger
within the said passage, two sets of openings in the plunger, a shoulder at its lower
end and a rubber band or washer around the shoulder, the lower part being placed
within the chamber or recess, substantially as described and shown in the
accompanying drawings, and for the purposes specified.
