Improvements in Cooks and Ball Valves.
I, EDWIN JOHN CHEYNEY 185 Cator Street Commercial Road Peckham
London Plumber, do hereby declare the nature of this invention to be as
follows:-
This invention rolates to improvements in cocks for taps and connections and
ball valves for cisterns and has for its object to provide an arrangement by means
of which the leather or other washers commonly employed may be dispensed with,
thereby overcoming the disadvantages continually experienced in connection with
such articles owing to their becoming loose and allowing the liquid to escape.
In carrying out my invention, I form the seating for the plug of a conical shape,
and the plug correspondingly conical, being ground in the scating to onsure a water
tight connection, For ball valves this plug is connected to the lover in the usual
manner taking the place of the present valves.
The cock according to my invention is formed with several conical sentiugs into
which fit correspondingly shaped pieces or plugs; the conical plug controlling the
passage for the water fits into a seating corresponding to that employed in the ball
valves and moves vertically being provented from turning by a projecting piece, on
each side sliding in vertical grooves in the casing.
The plug is furnished with a stem screwed at its upper end; which projects into
a tapped nut of double conical form which is constructed as an extension of the
handle.
The handle and conical nut are supported in a bearing pieco having n
conical seat on which the lower end of the nut resta being fastened in place by
a small cap screwing into the bearing piece, bevelled internally to fit on the upper
side of the nut and hold it in place. When the put or seating gots worn the cap
can be screwed down a little, tightening them to the required degree. The bearing
piece has a conical end which fits into the casing or projecting part of the tap or
pipe, which is screwed externally, a cap fitting over it and fixing the bearing piece
in place by means of a shoulder at its lower end. When the handle is turned the
nut will screw the plug up or down, opening or closing the passage, the projections
and grooves preventing it turning with the nut.
A number of conical seatings and corresponding plugs are thus provided, each of
which can be adjusted when worn by simply turning a screwed cap, all necessity
for washers or packing being thus dispensed with, as the water would require to
penetrate through three closely fitting conical joints before it could escape through
the npper part of the cook.

Improvements in Cooks and Ball Valves.
I, EDWIN JOHN CHEYNEY of 186, Cator Street, Commercial Road, Peckham,
London, Plumber, do. hereby declare the nature of this invention and in what
manner the same is to be performed, to bo particularly described and ascertained
in and by the following statement :—
This invention relates to improvements in cooks for taps and connections and
ball valves for cisterns, and has for its object to provide an arrangement by means
rn •

page_text: of which the leather or other washors commonly employed may be dispensed with,
thereby overcoming the disadvantages continually experienced in conuection with
such articles, owing to their becoming loose and allowing the liquid to escape. The
tap is especially adapted for hot water service.
In carrying out my invention I form the seating for the plug of a conical shape,
and the plug correspondingly conical being ground in the seating to ensure a water
tight connection. For ball valves this plug is connected to the lever in the usual
manuer taking the place of the present valve.
The cock according to my invention is formed with several conical seatings, into
which fit correspondingly shaped pieces or plugs, the conical plug controlling the
passage for the water fits into a seating corresponding to that employed in the ball
valve, and moves vertically, being prevented from turning by a projecting piece on
each side, sliding in vertical grooves in the casing. The plug is furnished with a
stem screwed at its upper end which projects into a tapped nat of conical form,
which is constructed as an extension of the handle. The handle and conical nut
are supported in a bearing piece having a conical sent on which the lower end of
the nut rests, being fastened in place by a small cap screwing into the bearing piece.
When the nut or seating gets worn, the cap can be screwed down a little, tightening
them to tho required degree. The bearing piece has a couical end which fits into
the casing or projecting part of the tap or pipe, which is screwed externally, a
cap fitting over it and fixing the bearing piece in place by means of a shoulder at
its lower end. When tho handle is turned, the nut will screw the plug up or down,
opening or closing the passage the projections and grooves proventing it turning
with the nut. A number of conical seatings and corresponding plugs are thus
provided, each of which can be adjusted when worn by simply turning a screwed
cap, all necessity for washers or packing being thus dispensed with, as tho wator
would require to penetrate through several closely fitting conical joints, before it
could escape through the upper part of the cock.
In order that the invention may be more clearly understooxi, reference is hail to
the accompanying shoot of drawings, in which
Fig. 1 is a section of the complete tap constructed in the manner above described,
Fig. 2 is a section showing part of the device, and
Fig. 3 shows the improved valve for cisterns and the like.
Referring to Figs. 1 & 2 A is the casing of the tap having a seating a inside of
similar or uearly similar form to that commonly employed in scrow taps. The
tubular extensions a' of this casing is screwed and furnished at its upper end with
a conical seating a³, and a vertical groove a' on each side for the purpose hereinafter
described. The plug B which I propose to employ in this cap is of truncated
conical form, as shown, and fits in the seating a. A very fine ridge is preferably
formed on the cone, at about the line where it meets the seat, which sorves to cut
away any deposit that might interfere with the proper working. This plug is
furnished with a cylindrical part B', which fits loosely in the tubular extension a,
and moves .vertically therein, wing pieces or ribs & taking into the grooves a³, to
prevent the plug turning. Projecting upwards is a serowed rod or stem b' by which
the plug is raised or lowered on turning the handle C of the tap. To effect this
movement the handle rod a is furnished with the tapped hole c', into which the
rod 'screws, so that if the handle is provented from moving vertically, on turning
it the rod will be screwed in or out of the tapped hole. The rode has also a
conical end the upper part of which forms a shoulder by which the rod is held in
place. The intermediate piece D has a conical seating d'in which the conical end
or nut c' turns, the piece 1 having bevelled edges resting in the conical seating a
in the part a' above referred to. This piece D is secured by the nut E bearing on
the shoulder d', and screwing on to the extension of the casing. The handle and
rod are secured in its seating by the nut F, bearing on the shoulder above mentioned,
and screwing into the intermediate picce D. Referring to Fig. 3 the supply pipe A'
is furnished with a conical soating a of suitable dimensions, and the downwardly
projecting part a' in which the plug B moves, the conical end of which fits in the

page_text: Beating a. The ball lever G turns on a pivot g on the end of the supply pipe or
other convenient part, and is connected to a loop & at the bottom of the plug,
raising or lowering the plug as the ball is raised or lowered by the liquid.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is.-
1. A cook for taps, having a conical plug resting when closed in a suitable
Beating in the casing of the tap, with a screw stem turning in a tapped hole in the
handle rod, the latter furnished with a conical end resting in a conical seating,
substantially as described and for the purposes specified.
2. A cock for taps in which a conical plug is employed, having a screwed stem
and a rib engaging with a groove in the casing of the tap to prevent the plug
turning, and a handle with conical end resting in a suitably coned bearing and
tapped hole in which the plug stem sorews, substantially as described.
3. In a cock for taps, the combination with the casing of the tap having a suitablo
plug seating, a screwed tubular extension with inner edge of top bevelled, and
furnished with a groove or grooves, of a conical plug with rib or ribs, and screwed
stem, a handle having rod with conical end and tapped hole, and an intermediate
piece fitting on top of tubular extension of casing, with a conical bearing in which
the end of handle rod rests, handle rod and intermediate piece both being fastened
by suitable nuts, substantially as described and shown.
4. The improved tap with conical seatings and plug constructed substantially as
described and illustrated in the accompanying drawings, and for the purposes
specified.
5. The improved valve for cisterns in which a conical seating is provided in the
end of the supply pipe, and a correspondingly conical plug is employed resting in
the seating and connected to the ball arm so as to be raised and lowered by it,
substantially as described and shown in Fig. 3 of the drawings, and for the
purposes specified.
