IN GAS, STEAM, OR WATER COCKS."
Sealed the 15th August 1871, and dated the 8th March 1871.
PROVISIONAL SPECIFICATION left by the said William George Cannon
at the Office of the Commissioners of Patents, with his Petition,
on the 8th March 1871.
I, WILLIAM GEORGE CANNON, of No. 52, New Kent Road, in the
3 County of Surry, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT IN GAS, STEAM, OR WATER COCкs," to be as follows:-
1st. A spindle passing through the center of the plug and through
the bottom of the barrel and held by a stop at the end of spindle fitting
between two ears E at the bottom of the barrel, the spindle A to be of
iron, steel, gun metal, or brass, and a cap F to screw on the bottom of
the barrel touching the spindle, keeping it firm between the two ears E
at the bottom of the barril to prevent the spindle from turning or shifting
when turning the cock off or on.

page_text: 2nd. The barrel C to be of the ordonary discription with the exception
of the bottom as above discribed and shown in Drawing Nomber One,
Fig. No. 1.
3rd. The plug B to be turned and well ground in the taper bore of
the barrel, and haveing a copper, brass, or other metal tubo G passing t
through center of the plug from top to bottom soldered or brazed to the
plug top and bottom, the bore of the tube allowing the spindle to pass
through freeley.
4th. A screwd nut H and a washer I to fit on the top of the spindle,
the spindle being scrowd to receive the same and holding the plug in 1
the barrel on its proper bearing.
5th. A cap J to be fitted on the top of the plug encloseing the nut
washer and top of spindle, and held to the plug by means of four screws
K (more or less), the screws entering in the top of the plug, the plug
being drilld and tapped to receave the same as shown on Drawing, Fig. 1, 1
the cap being drilld and countersunk to receave the heads of screws,
and screwed down firmley to top of the plug the top of the cap havcing
triangular, or square, or other shape projection for the purpose of
receaving a key to turn the cock on or off.
The advantages claimed is the vacility in takeing the plug from the 2
barrel for the purpose of greaseing and repairing, or in case of stoppage
in any pipes connected with the said cocks, and where cocks are fixed in
the walls without removcing or interfaring with any part of the barrel,
or cutting away any walls, plaster, or other materials where barrels are
fixed; these cocks may be made of brass, iron, or gun metal.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William George Cannon in the Great Seal Patont
Office on the 5th September 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GEORGE CANNON, of No. 52, New Kent Road, in the County of Surrey,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of March, in the year of

page_text: our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William George Cannon, Her special
licence that I, the said William George Cannon, my executors, admi-
nistrators, and assigns, or such others as I, the said William George
Cannon, my exccutors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVEMENT IN GAS, STEAM, OR WATER COCKS," upon the condition (amongst
others) that I, the said William George Cannon, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said William George Cannon, do hereby
declare the nature of the said Invention, and in what manner the samo
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :-
First. A spindle (A) passing through the centre of the plug (B) and
through the bottom of the barrel (C), and held by a stop (D) at the
end of the spindle, the said stop fitting between two cars (E) at the
bottom of the barrel, the spindle to be of iron, steel, gun metal, or
brass, and a cap (F) to screw on the bottom of the barrel, touching the
stop at the end of the spindle keeping the spindle firm between the
two ears at the bottom of the barrel to prevent the said spindle from
turning or shifting when turning the said cock off and on.
Second. The barrel may be of the ordinary shape or pattern with
the exception of the bottom as above described and shewn on Drawing
Figure No. 1.
Third. The plug is to be turned and well ground into the taper bore of the
barrel and having a copper, brass, or other metal tube (G) passing through
the centre of the plug from the top to the bottom, soldered or brazed to
the plug at the top and bottom, or cast with the plug and bored or drilled
out, the bore of the said tube allowing the spindle to pass through freely.

page_text: Fourth. A screwed nut (II) and a washer (1) to fit on the top of the
spindle, the spindle being screwed to receive the nut, the said nut to
touch the washer, the washer to pass over the screwed post of the
spindle, touching the plug and holding the plug in the barrel on its
proper bearings.

Fifth. A cap (J) to be fitted on the top of tho plug enclosing the
nut, and the washer and the top of the spindle held to the plug by four
scrows (R) (more or less), the screws entering the top of the pług, the
plug being drilled and tapped to receive the same as shown on Drawing
Figure 1, the cap being drilled and countersunk to receive the heads of 1
the screws, and screwed down firmly to the top of the plug, the top
of the cap having a square, triangular, or other shaped projection, or
sunk holes, for the purpose of receiving a key for turning the said cock
off and on.
Sixth. The said cock will serve for the purpose of a regulator by 1
having a dial fixed on the top of the barrel as shewn on Drawing
Figures Nos. 1, 2, and 3, letter (M), and having an indicator Figuro
No. 3, letter (P) screwed or fixed to the top part of the cap which
is fixed on the top of the plug and revolving with the plug when
turning the said cock off and on, the indicator being at a sufficient 2
distance not to touch the front part of the engraved or lettered dial.
Theso cocks may be made in brass, iron, gun, or other metal. The
front of these cocks may be made to any shape, pattern, or design or
made to any size required.
A Drawing is attached to this Specification showing section, Figuro 2
No. 1; clevation, Figure No. 2; plan, Figure No. 3; plan of washer,
Figure No. 4; plan of nut, Figure No. 5; key for turning the cock off
and on, Figure No. 6; spindle, Figure No. 7; bottom of cock with the
bottom cap off, Figure No. 8; bottom of cock with the bottom cap on,
Figure No. 9; the plug, Figure No. 10; top cap, Figure 11; plan of 3
the top of the plug, Figure 12. The Drawing represents the real size of
the 1-inch cock.
The advantage claimed is the facility in taking the plug from the
barrel for the purpose of greasing the bearings and grinding in the plug
when out of repair or in case of stoppage in any pipes connected with 3
the said cock without interfering with the barrel of the cock and to
take the plug from the barrel without cutting away any of the wall
-plaster or other materials where the said cocks are fixed.

page_text: What I claim in my Invention is the part or parts of the said cock
connected with the plug and the bottom of the barrel for keeping the
plug on its proper bearings in the barrel by the arrangements of the
spindle and the tube through the centre of the plug, the tube enclosing
part of the spindle in the plug and stopping the escape of gas, water,
or other fluid through the holes at the top and bottom of the plug
through which the spindle passes, also the arrangements of the ears at
the bottom of the barrel for the purpose of keeping the spindle in the
centre through the plug, and the screw and washer on the top of the
spindle pressing the top of the plug to keep the plug in the barrel on
its proper bearings.
In witness whereof, I, the said William George Cannon, have
hereunto set my hand and scal, this 5 day of September, in
the year of our Lord One thousand eight hundred and-seventy-
onc.
